Also fixes a comparison in the unit tests that would fail if you did not have a particular environment variable set. --- src/win32/utf-conv.c | 23 ++++++++++------------- tests-clar/core/env.c | 6 +++++- 2 files changed, 15 insertions(+), 14 deletions(-) diff --git a/src/win32/utf-conv.c b/src/win32/utf-conv.c index 76f1e4237..0a705c0ad 100644 --- a/src/win32/utf-conv.c +++ b/src/win32/utf-conv.c @@ -32,19 +32,16 @@ void gitwin_set_utf8(void) wchar_t* gitwin_to_utf16(const char* str) { wchar_t* ret; - size_t cb; + int cb; if (!str) return NULL; - cb = strlen(str) * sizeof(wchar_t); + cb = MultiByteToWideChar(_active_codepage, 0, str, -1, NULL, 0); if (cb == 0) return (wchar_t *)git__calloc(1, sizeof(wchar_t)); - /* Add space for null terminator */ - cb += sizeof(wchar_t); - - ret = (wchar_t *)git__malloc(cb); + ret = (wchar_t *)git__malloc(cb * sizeof(wchar_t)); if (!ret) return NULL; @@ -59,7 +56,8 @@ wchar_t* gitwin_to_utf16(const char* str) int gitwin_append_utf16(wchar_t *buffer, const char *str, size_t len) { - int result = MultiByteToWideChar(_active_codepage, 0, str, -1, buffer, (int)len); + int result = MultiByteToWideChar( + _active_codepage, 0, str, -1, buffer, (int)len); if (result == 0) giterr_set(GITERR_OS, "Could not convert string to UTF-16"); return result; @@ -68,23 +66,22 @@ int gitwin_append_utf16(wchar_t *buffer, const char *str, size_t len) char* gitwin_from_utf16(const wchar_t* str) { char* ret; - size_t cb; + int cb; if (!str) return NULL; - cb = wcslen(str) * sizeof(char); + cb = WideCharToMultiByte(_active_codepage, 0, str, -1, NULL, 0, NULL, NULL); if (cb == 0) return (char *)git__calloc(1, sizeof(char)); - /* Add space for null terminator */ - cb += sizeof(char); - ret = (char*)git__malloc(cb); if (!ret) return NULL; - if (WideCharToMultiByte(_active_codepage, 0, str, -1, ret, (int)cb, NULL, NULL) == 0) { + if (WideCharToMultiByte( + _active_codepage, 0, str, -1, ret, (int)cb, NULL, NULL) == 0) + { giterr_set(GITERR_OS, "Could not convert string to UTF-8"); git__free(ret); ret = NULL; diff --git a/tests-clar/core/env.c b/tests-clar/core/env.c index bd1a94244..abe7bf87c 100644 --- a/tests-clar/core/env.c +++ b/tests-clar/core/env.c @@ -15,12 +15,16 @@ static char *cl_getenv(const char *name) cl_assert(name_utf16); alloc_len = GetEnvironmentVariableW(name_utf16, NULL, 0); - if (alloc_len < 0) + if (alloc_len <= 0) return NULL; + cl_assert(value_utf16 = git__calloc(alloc_len, sizeof(wchar_t))); + value_len = GetEnvironmentVariableW(name_utf16, value_utf16, alloc_len); cl_assert_equal_i(value_len, alloc_len - 1); + cl_assert(value_utf8 = gitwin_from_utf16(value_utf16)); + git__free(value_utf16); return value_utf8; -- cgit v1.2.3 From 349fb6d7acd2d57fb5c0039e7f1228cff1702b13 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Vicent=20Mart=C3=AD?= Date: Thu, 24 May 2012 23:04:41 +0200 Subject: windows: Properly expand all environment variables --- src/fileops.c | 154 +++++++++++++++++++--------------------------------------- 1 file changed, 51 insertions(+), 103 deletions(-) diff --git a/src/fileops.c b/src/fileops.c index 6dd9270b5..0e7d43bab 100644 --- a/src/fileops.c +++ b/src/fileops.c @@ -354,110 +354,22 @@ int git_futils_rmdir_r(const char *path, git_directory_removal_type removal_type } #ifdef GIT_WIN32 -static char *win32_getenv(const wchar_t *name) -{ - char *val_utf8; - wchar_t *val_utf16; - DWORD len = GetEnvironmentVariableW(name, NULL, 0); - - if (len <= 0) - return NULL; - - val_utf16 = git__calloc(len, sizeof(wchar_t)); - if (!val_utf16) - return NULL; - - if (GetEnvironmentVariableW(name, val_utf16, len) != len - 1) { - giterr_set(GITERR_OS, "Could not read environment variable"); - git__free(val_utf16); - return NULL; - } - - val_utf8 = gitwin_from_utf16(val_utf16); - - git__free(val_utf16); - - return val_utf8; -} -#endif - -int git_futils_find_global_file(git_buf *path, const char *filename) -{ - char *home; - -#ifdef GIT_WIN32 - home = win32_getenv(L"HOME"); - - if (!home) - home = win32_getenv(L"USERPROFILE"); - - if (home) - git_path_mkposix(home); -#else - home = getenv("HOME"); -#endif - - if (home == NULL) { - giterr_set(GITERR_OS, "Global file lookup failed.

This was caused by reusing the "fnmatch" parsing code from ignore and attribute files to interpret the "pathspec" that constrained the files to apply the status to. In that code, unescaped whitespace was considered terminal to the pattern, so a file with internal whitespace was excluded from the matched files. The fix was to add a mode to that code that allows spaces and tabs inside patterns. This mode only comes into play when parsing in-memory strings. * The other issue was undetected, but it was in the recently added code to reload gitattributes / gitignores when they were changed on disk. That code was not clearing out the old values from the cached file content before reparsing which meant that newly added patterns would be read in, but deleted patterns would not be removed. The fix was to clear the vector of patterns in a cached file before reparsing the file. --- src/attr.c | 11 ++++++-- src/attr_file.c | 26 +++++++++++------ src/attr_file.h | 3 ++ src/diff.c | 1 + tests-clar/attr/attr_expect.h | 7 +++-- tests-clar/attr/file.c | 2 +- tests-clar/attr/lookup.c | 2 +- tests-clar/attr/repo.c | 2 +- tests-clar/core/env.c | 5 +++- tests-clar/status/worktree.c | 65 +++++++++++++++++++++++++++++++++++++++++++ 10 files changed, 105 insertions(+), 19 deletions(-) diff --git a/src/attr.c b/src/attr.c index 093f64d5c..fb6651196 100644 --- a/src/attr.c +++ b/src/attr.c @@ -403,9 +403,14 @@ int git_attr_cache__push_file( goto finish;

The underlying bug was that git__strcmp_cb, which is used by git_path_with_stat_cmp to sort entries in the working directory, compares strings based on unsigned chars (this is confirmed by the strcmp(3) manpage), while git__prefixcmp, which is used by workdir_iterator__entry_cmp to search for a path in the working directory, compares strings based on char. So the sort puts this path at the end of the list, while the search expects it to be at the beginning. The fix was simply to make git__prefixcmp compare using unsigned chars, just like strcmp(3). The rest of the change is just adding/updating tests. --- src/util.c | 2 +- tests-clar/diff/iterator.c | 8 +++++--- tests-clar/diff/workdir.c | 20 ++++++++++---------- "tests-clar/resources/status/\350\277\231" | 1 + tests-clar/status/status_data.h | 16 ++++++++++++---- 5 files changed, 29 insertions(+), 18 deletions(-) create mode 100644 "tests-clar/resources/status/\350\277\231" diff --git a/src/util.c b/src/util.c index ce770203a..3093cd767 100644 --- a/src/util.c +++ b/src/util.c @@ -179,7 +179,7 @@ void git__strtolower(char *str) int git__prefixcmp(const char *str, const char *prefix) { for (;;) { - char p = *(prefix++), s; + unsigned char p = *(prefix++), s; if (!p) return 0; if ((s = *(str++)) != p) diff --git a/tests-clar/diff/iterator.c b/tests-clar/diff/iterator.c index be29bea66..eee84810a 100644 --- a/tests-clar/diff/iterator.c +++ b/tests-clar/diff/iterator.c @@ -474,13 +474,14 @@ static const char *status_paths[] = { "subdir/current_file", "subdir/modified_file", "subdir/new_file", + "\xe8\xbf\x99", NULL }; void test_diff_iterator__workdir_1(void) { workdir_iterator_test( - "status", NULL, NULL, 12, 1, status_paths, "ignored_file"); + "status", NULL, NULL, 13, 1, status_paths, "ignored_file"); } static const char *status_paths_range_0[] = { @@ -527,13 +528,14 @@ static const char *status_paths_range_4[] = { "subdir/current_file", "subdir/modified_file", "subdir/new_file", + "\xe8\xbf\x99", NULL }; void test_diff_iterator__workdir_1_ranged_4(void) { workdir_iterator_test( - "status", "subdir/", NULL, 3, 0, status_paths_range_4, NULL); + "status", "subdir/", NULL, 4, 0, status_paths_range_4, NULL); } static const char *status_paths_range_5[] = { @@ -551,7 +553,7 @@ void test_diff_iterator__workdir_1_ranged_5(void) void test_diff_iterator__workdir_1_ranged_empty_0(void) { workdir_iterator_test( - "status", "z_does_not_exist", NULL, + "status", "\xff_does_not_exist", NULL, 0, 0, NULL, NULL); } diff --git a/tests-clar/diff/workdir.c b/tests-clar/diff/workdir.c index 1ea1af86a..42152f1ad 100644 --- a/tests-clar/diff/workdir.c +++ b/tests-clar/diff/workdir.c @@ -37,12 +37,12 @@ void test_diff_workdir__to_index(void) * - git diff * - mv .git .gitted */ - cl_assert_equal_i(12, exp.files); + cl_assert_equal_i(13, exp.files); cl_assert_equal_i(0, exp.file_adds); cl_assert_equal_i(4, exp.file_dels); cl_assert_equal_i(4, exp.file_mods); cl_assert_equal_i(1, exp.file_ignored); - cl_assert_equal_i(3, exp.file_untracked); + cl_assert_equal_i(4, exp.file_untracked); cl_assert_equal_i(8, exp.hunks); @@ -87,12 +87,12 @@ void test_diff_workdir__to_tree(void) cl_git_pass(git_diff_foreach( diff, &exp, diff_file_fn, diff_hunk_fn, diff_line_fn)); - cl_assert(exp.files == 13); + cl_assert(exp.files == 14); cl_assert(exp.file_adds == 0); cl_assert(exp.file_dels == 4); cl_assert(exp.file_mods == 4); cl_assert(exp.file_ignored == 1); - cl_assert(exp.file_untracked == 4); + cl_assert(exp.file_untracked == 5); /* Since there is no git diff equivalent, let's just assume that the * text diffs produced by git_diff_foreach are accurate here.

There is no code that automatically toggles core.filemode based on the capabilities of the current platform, so the user still needs to be careful in their .git/config file. --- include/git2/status.h | 2 +- src/diff.c | 41 +++++--- src/diff.h | 5 +- src/diff_output.c | 13 ++- tests-clar/clar_helpers.c | 24 +++++ tests-clar/clar_libgit2.h | 3 + tests-clar/diff/workdir.c | 109 ++++++++++++++++++++- tests-clar/resources/filemodes/.gitted/HEAD | 1 + tests-clar/resources/filemodes/.gitted/config | 6 ++ tests-clar/resources/filemodes/.gitted/description | 1 + .../filemodes/.gitted/hooks/commit-msg.sample | 24 +++++ tests-clar/resources/filemodes/.gitted/index | Bin 0 -> 528 bytes .../resources/filemodes/.gitted/info/exclude | 6 ++ tests-clar/resources/filemodes/.gitted/logs/HEAD | 1 + .../filemodes/.gitted/logs/refs/heads/master | 1 + .../99/62c8453ba6f0cf8dac7c5dcc2fa2897fa9964a | Bin 0 -> 139 bytes .../a5/c5dd0fc6c313159a69b1d19d7f61a9f978e8f1 | Bin 0 -> 21 bytes .../e7/48d196331bcb20267eaaee4ff3326cb73b8182 | Bin 0 -> 99 bytes .../resources/filemodes/.gitted/refs/heads/master | 1 + tests-clar/resources/filemodes/exec_off | 1 + tests-clar/resources/filemodes/exec_off2on_staged | 1 + tests-clar/resources/filemodes/exec_off2on_workdir | 1 + tests-clar/resources/filemodes/exec_off_untracked | 1 + tests-clar/resources/filemodes/exec_on | 1 + tests-clar/resources/filemodes/exec_on2off_staged | 1 + tests-clar/resources/filemodes/exec_on2off_workdir | 1 + tests-clar/resources/filemodes/exec_on_untracked | 1 + tests-clar/status/worktree.c | 66 +++++++++++++ 28 files changed, 289 insertions(+), 23 deletions(-) create mode 100644 tests-clar/resources/filemodes/.gitted/HEAD create mode 100644 tests-clar/resources/filemodes/.gitted/config create mode 100644 tests-clar/resources/filemodes/.gitted/description create mode 100755 tests-clar/resources/filemodes/.gitted/hooks/commit-msg.sample create mode 100644 tests-clar/resources/filemodes/.gitted/index create mode 100644 tests-clar/resources/filemodes/.gitted/info/exclude create mode 100644 tests-clar/resources/filemodes/.gitted/logs/HEAD create mode 100644 tests-clar/resources/filemodes/.gitted/logs/refs/heads/master create mode 100644 tests-clar/resources/filemodes/.gitted/objects/99/62c8453ba6f0cf8dac7c5dcc2fa2897fa9964a create mode 100644 tests-clar/resources/filemodes/.gitted/objects/a5/c5dd0fc6c313159a69b1d19d7f61a9f978e8f1 create mode 100644 tests-clar/resources/filemodes/.gitted/objects/e7/48d196331bcb20267eaaee4ff3326cb73b8182 create mode 100644 tests-clar/resources/filemodes/.gitted/refs/heads/master create mode 100644 tests-clar/resources/filemodes/exec_off create mode 100755 tests-clar/resources/filemodes/exec_off2on_staged create mode 100755 tests-clar/resources/filemodes/exec_off2on_workdir create mode 100644 tests-clar/resources/filemodes/exec_off_untracked create mode 100755 tests-clar/resources/filemodes/exec_on create mode 100644 tests-clar/resources/filemodes/exec_on2off_staged create mode 100644 tests-clar/resources/filemodes/exec_on2off_workdir create mode 100755 tests-clar/resources/filemodes/exec_on_untracked diff --git a/include/git2/status.h b/include/git2/status.h index 6a424dfd6..69b6e47e0 100644 --- a/include/git2/status.h +++ b/include/git2/status.h @@ -102,7 +102,7 @@ enum { GIT_STATUS_OPT_INCLUDE_UNTRACKED = (1 << 0), GIT_STATUS_OPT_INCLUDE_IGNORED = (1 << 1), GIT_STATUS_OPT_INCLUDE_UNMODIFIED = (1 << 2), - GIT_STATUS_OPT_EXCLUDE_SUBMODULED = (1 << 3), + GIT_STATUS_OPT_EXCLUDE_SUBMODULES = (1 << 3), GIT_STATUS_OPT_RECURSE_UNTRACKED_DIRS = (1 << 4), }; diff --git a/src/diff.c b/src/diff.c index 90baa9588..e3167b90e 100644 --- a/src/diff.c +++ b/src/diff.c @@ -214,7 +214,9 @@ static int diff_delta__from_two( git_diff_list *diff, git_delta_t status, const git_index_entry *old_entry, + uint32_t old_mode, const git_index_entry *new_entry, + uint32_t new_mode, git_oid *new_oid) { git_diff_delta *delta; @@ -224,19 +226,22 @@ static int diff_delta__from_two( return 0; if ((diff->opts.flags & GIT_DIFF_REVERSE) != 0) { - const git_index_entry *temp = old_entry; + uint32_t temp_mode = old_mode; + const git_index_entry *temp_entry = old_entry; old_entry = new_entry; - new_entry = temp; + new_entry = temp_entry; + old_mode = new_mode; + new_mode = temp_mode; } delta = diff_delta__alloc(diff, status, old_entry->path); GITERR_CHECK_ALLOC(delta); - delta->old_file.mode = old_entry->mode; + delta->old_file.mode = old_mode; git_oid_cpy(&delta->old_file.oid, &old_entry->oid); delta->old_file.flags |= GIT_DIFF_FILE_VALID_OID; - delta->new_file.mode = new_entry->mode; + delta->new_file.mode = new_mode; git_oid_cpy(&delta->new_file.oid, new_oid ?

145e696b498a046762e4df9045c9b71440308486 Mon Sep 17 00:00:00 2001 From: Russell Belfer Date: Fri, 8 Jun 2012 11:56:24 -0700 Subject: Minor fixes, cleanups, and clarifications There are three actual changes in this commit: 1. When the trailing newline of a file is removed in a diff, the change will now be reported with `GIT_DIFF_LINE_DEL_EOFNL` passed to the callback. Previously, the `ADD_EOFNL` constant was given which was just an error in my understanding of when the various circumstances arose. `GIT_DIFF_LINE_ADD_EOFNL` is deprecated and should never be generated. A new newline is simply an `ADD`. 2. Rewrote the `diff_delta__merge_like_cgit` function that contains the core logic of the `git_diff_merge` implementation. The new version doesn't actually have significantly different behavior, but the logic should be much more obvious, I think. 3. Fixed a bug in `git_diff_merge` where it freed a string pool while some of the string data was still in use. This led to `git_diff_print_patch` accessing memory that had been freed. The rest of this commit contains improved documentation in `diff.h` to make the behavior and the equivalencies with core git clearer, and a bunch of new tests to cover the various cases, oh and a minor simplification of `examples/diff.c`. --- examples/diff.c | 4 +- include/git2/diff.h | 91 ++++++++++++++----- src/diff.c | 63 ++++++++----- src/diff_output.c | 11 +-- tests-clar/diff/diff_helpers.c | 7 +- tests-clar/diff/tree.c | 2 +- tests-clar/diff/workdir.c | 195 +++++++++++++++++++++++++++++++++++------ 7 files changed, 291 insertions(+), 82 deletions(-) diff --git a/examples/diff.c b/examples/diff.c index 1b4ab549b..b72a75e1c 100644 --- a/examples/diff.c +++ b/examples/diff.c @@ -185,9 +185,7 @@ int main(int argc, char *argv[]) /* open repo */ - check(git_repository_discover(path, sizeof(path), dir, 0, "/"), - "Could not discover repository"); - check(git_repository_open(&repo, path), + check(git_repository_open_ext(&repo, dir, 0, NULL), "Could not open repository"); if (treeish1) diff --git a/include/git2/diff.h b/include/git2/diff.h index 46b80d872..d4d0eac47 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -29,6 +29,10 @@ */ GIT_BEGIN_DECL +/** + * Flags for diff options.

This also has placeholder support for core.symlinks and core.ignorecase, but those flags are not implemented (well, symlinks has partial support for preserving mode information in the same way that git does, but it isn't tested). --- include/git2/index.h | 29 ++++++ src/diff.c | 4 +- src/index.c | 88 ++++++++++++++---- src/index.h | 5 + src/repository.c | 3 + tests-clar/clar_helpers.c | 9 +- tests-clar/clar_libgit2.h | 2 +- tests-clar/index/filemodes.c | 212 +++++++++++++++++++++++++++++++++++++++++++ 8 files changed, 327 insertions(+), 25 deletions(-) create mode 100644 tests-clar/index/filemodes.c diff --git a/include/git2/index.h b/include/git2/index.h index 0fb0f955a..b8897ea91 100644 --- a/include/git2/index.h +++ b/include/git2/index.h @@ -90,6 +90,14 @@ typedef struct git_index_entry_unmerged { char *path; } git_index_entry_unmerged; +/** Capabilities of system that affect index actions. */ +enum { + GIT_INDEXCAP_IGNORE_CASE = 1, + GIT_INDEXCAP_NO_FILEMODE = 2, + GIT_INDEXCAP_NO_SYMLINKS = 4, + GIT_INDEXCAP_FROM_OWNER = (unsigned int)-1 +}; + /** * Create a new bare Git index object as a memory representation * of the Git index file in 'index_path', without a repository @@ -126,6 +134,27 @@ GIT_EXTERN(void) git_index_clear(git_index *index); */ GIT_EXTERN(void) git_index_free(git_index *index); +/** + * Read index capabilities flags. + * + * @param index An existing index object + * @return A combination of GIT_INDEXCAP values + */ +GIT_EXTERN(unsigned int) git_index_caps(const git_index *index); + +/** + * Set index capabilities flags. + * + * If you pass `GIT_INDEXCAP_FROM_OWNER` for the caps, then the + * capabilities will be read from the config of the owner object, + * looking at `core.ignorecase`, `core.filemode`, `core.symlinks`. + * + * @param index An existing index object + * @param caps A combination of GIT_INDEXCAP values + * @return 0 on success, -1 on failure + */ +GIT_EXTERN(int) git_index_set_caps(git_index *index, unsigned int caps); + /** * Update the contents of an existing index object in memory * by reading from the hard disk. diff --git a/src/diff.c b/src/diff.c index 02b89b46e..bc8708e33 100644 --- a/src/diff.c +++ b/src/diff.c @@ -456,10 +456,10 @@ static int maybe_modified( if (!diff_path_matches_pathspec(diff, oitem->path)) return 0; - /* on platforms with no symlinks, promote plain files to symlinks */ + /* on platforms with no symlinks, preserve mode of existing symlinks */ if (S_ISLNK(omode) && S_ISREG(nmode) && !(diff->diffcaps & GIT_DIFFCAPS_HAS_SYMLINKS)) - nmode = GIT_MODE_TYPE(omode) | (nmode & GIT_MODE_PERMS_MASK); + nmode = omode; /* on platforms with no execmode, just preserve old mode */ if (!(diff->diffcaps & GIT_DIFFCAPS_TRUST_MODE_BITS) && diff --git a/src/index.c b/src/index.c index f1ae9a710..3fedcd27a 100644 --- a/src/index.c +++ b/src/index.c @@ -15,6 +15,7 @@ #include "hash.h" #include "git2/odb.h" #include "git2/blob.h" +#include "git2/config.h" #define entry_size(type,len) ((offsetof(type, path) + (len) + 8) & ~7) #define short_entry_size(len) entry_size(struct entry_short, len) @@ -124,11 +125,27 @@ static unsigned int index_create_mode(unsigned int mode) { if (S_ISLNK(mode)) return S_IFLNK; + if (S_ISDIR(mode) || (mode & S_IFMT) == (S_IFLNK | S_IFDIR)) return (S_IFLNK | S_IFDIR); + return S_IFREG | ((mode & 0100) ? 0755 : 0644); } +static unsigned int index_merge_mode( + git_index *index, git_index_entry *existing, unsigned int mode) +{ + if (index->no_symlinks && S_ISREG(mode) && + existing && S_ISLNK(existing->mode)) + return existing->mode; + + if (index->distrust_filemode && S_ISREG(mode)) + return (existing && S_ISREG(existing->mode)) ? + existing->mode : index_create_mode(0666); + + return index_create_mode(mode); +} + int git_index_open(git_index **index_out, const char *index_path) { git_index *index; @@ -208,6 +225,45 @@ void git_index_clear(git_index *index) index->tree = NULL; } +int git_index_set_caps(git_index *index, unsigned int caps) +{ + assert(index); + + if (caps == GIT_INDEXCAP_FROM_OWNER) { + git_config *cfg; + int val; + + if (INDEX_OWNER(index) == NULL || + git_repository_config__weakptr(&cfg, INDEX_OWNER(index)) < 0) + { + giterr_set(GITERR_INDEX, + "Cannot get repository config to set index caps"); + return -1; + } + + if (git_config_get_bool(&val, cfg, "core.ignorecase") == 0) + index->ignore_case = (val != 0); + if (git_config_get_bool(&val, cfg, "core.filemode") == 0) + index->distrust_filemode = (val == 0); + if (git_config_get_bool(&val, cfg, "core.symlinks") == 0) + index->no_symlinks = (val != 0); + } + else { + index->ignore_case = ((caps & GIT_INDEXCAP_IGNORE_CASE) != 0); + index->distrust_filemode = ((caps & GIT_INDEXCAP_NO_FILEMODE) != 0); + index->no_symlinks = ((caps & GIT_INDEXCAP_NO_SYMLINKS) != 0); + } + + return 0; +} + +unsigned int git_index_caps(const git_index *index) +{ + return ((index->ignore_case ?

This can be applied to URLs as well as file paths which can be useful. As part of this, I made the drive-letter detection apply on all platforms, not just windows. If you give a path that looks like "c:/..." on any platform, it seems like we might as well detect that as a rooted path. I suppose if you create a directory named "x:" on another platform and want to use that as the beginning of a relative path under the root directory of your repo, this could cause a problem, but then it seems like you're asking for trouble. --- src/path.c | 69 +++++++++++++++++++++++++++++++++++++++++++++++--- src/path.h | 23 +++++++++++++++++ tests-clar/core/path.c | 51 +++++++++++++++++++++++++++++++++++++ 3 files changed, 140 insertions(+), 3 deletions(-) diff --git a/src/path.c b/src/path.c index 9c88240e0..e9bc4871c 100644 --- a/src/path.c +++ b/src/path.c @@ -17,9 +17,7 @@ #include #include -#ifdef GIT_WIN32 #define LOOKS_LIKE_DRIVE_PREFIX(S) (git__isalpha((S)[0]) && (S)[1] == ':') -#endif /* * Based on the Android implementation, BSD licensed. @@ -172,11 +170,11 @@ int git_path_root(const char *path) { int offset = 0; -#ifdef GIT_WIN32 /* Does the root of the path look like a windows drive ? */ if (LOOKS_LIKE_DRIVE_PREFIX(path)) offset += 2; +#ifdef GIT_WIN32 /* Are we dealing with a windows network path? */ else if ((path[0] == '/' && path[1] == '/') || (path[0] == '\\' && path[1] == '\\')) @@ -464,6 +462,71 @@ int git_path_find_dir(git_buf *dir, const char *path, const char *base) return error; } +int git_path_resolve_relative(git_buf *path, size_t ceiling) +{ + char *base, *to, *from, *next; + size_t len; + + if (!path || git_buf_oom(path)) + return -1; + + if (ceiling > path->size) + ceiling = path->size; + + /* recognize drive prefixes, etc. that should not be backed over */ + if (ceiling == 0) + ceiling = git_path_root(path->ptr) + 1; + + /* recognize URL prefixes that should not be backed over */ + if (ceiling == 0) { + for (next = path->ptr; *next && git__isalpha(*next); ++next); + if (next[0] == ':' && next[1] == '/' && next[2] == '/') + ceiling = (next + 3) - path->ptr; + } + + base = to = from = path->ptr + ceiling; + + while (*from) { + for (next = from; *next && *next != '/'; ++next); + + len = next - from; + + if (len == 1 && from[0] == '.') + /* do nothing with singleton dot */; + + else if (len == 2 && from[0] == '.' && from[1] == '.') { + while (to > base && to[-1] == '/') to--; + while (to > base && to[-1] != '/') to--; + } + + else { + if (*next == '/') + len++; + + if (to != from) + memmove(to, from, len); + + to += len; + } + + from += len; + + while (*from == '/') from++; + } + + *to = '\0'; + + path->size = to - path->ptr; + + return 0; +} + +int git_path_apply_relative(git_buf *target, const char *relpath) +{ + git_buf_joinpath(target, git_buf_cstr(target), relpath); + return git_path_resolve_relative(target, 0); +} + int git_path_cmp( const char *name1, size_t len1, int isdir1, const char *name2, size_t len2, int isdir2) diff --git a/src/path.h b/src/path.h index fd76805e5..d68393b3d 100644 --- a/src/path.h +++ b/src/path.h @@ -185,6 +185,29 @@ extern int git_path_prettify_dir(git_buf *path_out, const char *path, const char */ extern int git_path_find_dir(git_buf *dir, const char *path, const char *base); +/** + * Resolve relative references within a path. + * + * This eliminates "./" and "../" relative references inside a path, + * as well as condensing multiple slashes into single ones.

If you pass this flag as true, then setting the workdir to something other than the default workdir (i.e. the parent of the .git repo directory), will create a plain file named ".git" with the standard gitlink contents "gitdir: ", and also update the "core.worktree" and "core.bare" config values. Setting the workdir to the default repo workdir will clear the core.worktree flag (but still permanently set core.bare to false). BTW, the libgit2 API does not currently provide a function for clearing the workdir and converting a non-bare repo into a bare one. --- include/git2/repository.h | 5 ++- src/repository.c | 92 +++++++++++++++++++++++++++++++++++++++----- tests-clar/repo/setters.c | 31 +++++++++++++-- tests-clar/status/worktree.c | 4 +- 4 files changed, 116 insertions(+), 16 deletions(-) diff --git a/include/git2/repository.h b/include/git2/repository.h index 0b56a0870..ff81b75ec 100644 --- a/include/git2/repository.h +++ b/include/git2/repository.h @@ -194,9 +194,12 @@ GIT_EXTERN(const char *) git_repository_workdir(git_repository *repo);

The rules are: * A callback terminates the loop by returning any non-zero value * Once the callback returns non-zero, it will not be called again (i.e. the loop stops all iteration regardless of state) * If the callback returns non-zero, the parent fn returns GIT_EUSER * Although the parent returns GIT_EUSER, no error will be set in the library and `giterr_last()` will return NULL if called. This commit makes those changes across the library and adds tests for most of the iteration APIs to make sure that they follow the above rules. --- include/git2/attr.h | 21 ++++---- include/git2/branch.h | 4 +- include/git2/config.h | 4 +- include/git2/diff.h | 18 +++++++ include/git2/errors.h | 1 + include/git2/notes.h | 16 +++--- include/git2/odb.h | 7 +-- include/git2/refs.h | 5 +- include/git2/remote.h | 5 +- include/git2/status.h | 4 +- src/attr.c | 9 ++-- src/config_file.c | 4 +- src/diff_output.c | 103 +++++++++++++++++++++---------------- src/notes.c | 45 +++++++--------- src/odb.c | 5 +- src/odb_loose.c | 14 ++--- src/odb_pack.c | 9 ++-- src/pack.c | 11 ++-- src/path.h | 1 + src/refs.c | 22 +++++--- src/status.c | 22 +++++--- src/transports/git.c | 6 +-- src/transports/http.c | 6 +-- src/transports/local.c | 4 +- tests-clar/attr/repo.c | 22 ++++++++ tests-clar/config/read.c | 2 +- tests-clar/diff/index.c | 50 ++++++++++++++++++ tests-clar/notes/notes.c | 30 ++++++++++- tests-clar/odb/foreach.c | 18 +++++++ tests-clar/refs/branches/foreach.c | 25 +++++++++ tests-clar/refs/foreachglob.c | 22 ++++++++ tests-clar/status/worktree.c | 33 ++++++++++-- 32 files changed, 401 insertions(+), 147 deletions(-) diff --git a/include/git2/attr.h b/include/git2/attr.h index fad7183da..73a625a7e 100644 --- a/include/git2/attr.h +++ b/include/git2/attr.h @@ -172,18 +172,17 @@ GIT_EXTERN(int) git_attr_get_many( * * @param repo The repository containing the path. * @param flags A combination of GIT_ATTR_CHECK... flags. - * @param path The path inside the repo to check attributes.

Thus we could have the memory-mapped window information thread-local and avoid any locking. This is not practical in a few environments, such as Apple's GCD which allocates threads arbitrarily or the .NET CLR, where the OS-level thread can change at any moment. Make the control structure global and protect it with a mutex so we don't depend on the thread currently executing the code. --- src/global.c | 5 +++++ src/global.h | 4 ++-- src/mwindow.c | 48 +++++++++++++++++++++++++++++++++++++----------- src/mwindow.h | 1 - 4 files changed, 44 insertions(+), 14 deletions(-) diff --git a/src/global.c b/src/global.c index 368c6c664..691f0d4f6 100644 --- a/src/global.c +++ b/src/global.c @@ -9,6 +9,9 @@ #include "git2/threads.h" #include "thread-utils.h" + +git_mutex git__mwindow_mutex; + /** * Handle the global state with TLS * @@ -47,12 +50,14 @@ void git_threads_init(void) _tls_index = TlsAlloc(); _tls_init = 1; + git_mutex_init(&git__mwindow_mutex); } void git_threads_shutdown(void) { TlsFree(_tls_index); _tls_init = 0; + git_mutex_free(&git__mwindow_mutex); } git_global_st *git__global_state(void) diff --git a/src/global.h b/src/global.h index 6e7373fa3..0ad41ee63 100644 --- a/src/global.h +++ b/src/global.h @@ -12,12 +12,12 @@ typedef struct { git_error *last_error; git_error error_t; - - git_mwindow_ctl mem_ctl; } git_global_st; git_global_st *git__global_state(void); +extern git_mutex git__mwindow_mutex; + #define GIT_GLOBAL (git__global_state()) #endif diff --git a/src/mwindow.c b/src/mwindow.c index 1a5446b9c..4da5badb6 100644 --- a/src/mwindow.c +++ b/src/mwindow.c @@ -32,14 +32,20 @@ static struct { DEFAULT_MAPPED_LIMIT, }; +/* Whenever you want to read or modify this, grab git__mwindow_mutex */ +static git_mwindow_ctl mem_ctl; + /* * Free all the windows in a sequence, typically because we're done * with the file */ void git_mwindow_free_all(git_mwindow_file *mwf) { - git_mwindow_ctl *ctl = &GIT_GLOBAL->mem_ctl; + git_mwindow_ctl *ctl = &mem_ctl; unsigned int i; + + git_mutex_lock(&git__mwindow_mutex); + /* * Remove these windows from the global list */ @@ -67,6 +73,8 @@ void git_mwindow_free_all(git_mwindow_file *mwf) mwf->windows = w->next; git__free(w); } + + git_mutex_unlock(&git__mwindow_mutex); } /* @@ -82,7 +90,7 @@ int git_mwindow_contains(git_mwindow *win, git_off_t offset) /* * Find the least-recently-used window in a file */ -void git_mwindow_scan_lru( +static void git_mwindow_scan_lru( git_mwindow_file *mwf, git_mwindow **lru_w, git_mwindow **lru_l) @@ -107,11 +115,12 @@ void git_mwindow_scan_lru( /* * Close the least recently used window.

This also adds tests for much of the new functionality to the existing `repo/init.c` test suite. Also, this adds a bunch of new utility functions including a very general purpose `git_futils_mkdir` (with the ability to make paths and to chmod the paths post-creation) and a file tree copying function `git_futils_cp_r`. Also, this includes some new path functions that were useful to keep the code simple. --- include/git2/config.h | 12 + include/git2/repository.h | 47 +-- src/attr_file.c | 15 +- src/config.c | 25 ++ src/fileops.c | 338 ++++++++++++++++----- src/fileops.h | 83 ++++- src/path.c | 46 ++- src/path.h | 14 + src/posix.h | 7 + src/repository.c | 222 +++++++++----- src/repository.h | 1 - src/unix/posix.h | 1 + src/win32/posix.h | 8 + tests-clar/core/copy.c | 123 ++++++++ tests-clar/core/mkdir.c | 169 +++++++++++ tests-clar/repo/init.c | 82 ++++- tests-clar/resources/template/branches/.gitignore | 2 + tests-clar/resources/template/description | 1 + .../resources/template/hooks/applypatch-msg.sample | 15 + .../resources/template/hooks/commit-msg.sample | 24 ++ .../resources/template/hooks/post-commit.sample | 8 + .../resources/template/hooks/post-receive.sample | 15 + .../resources/template/hooks/post-update.sample | 8 + .../resources/template/hooks/pre-applypatch.sample | 14 + .../resources/template/hooks/pre-commit.sample | 46 +++ .../resources/template/hooks/pre-rebase.sample | 169 +++++++++++ .../template/hooks/prepare-commit-msg.sample | 36 +++ tests-clar/resources/template/hooks/update.sample | 128 ++++++++ tests-clar/resources/template/info/exclude | 6 + 29 files changed, 1481 insertions(+), 184 deletions(-) create mode 100644 tests-clar/core/copy.c create mode 100644 tests-clar/core/mkdir.c create mode 100644 tests-clar/resources/template/branches/.gitignore create mode 100644 tests-clar/resources/template/description create mode 100755 tests-clar/resources/template/hooks/applypatch-msg.sample create mode 100755 tests-clar/resources/template/hooks/commit-msg.sample create mode 100755 tests-clar/resources/template/hooks/post-commit.sample create mode 100755 tests-clar/resources/template/hooks/post-receive.sample create mode 100755 tests-clar/resources/template/hooks/post-update.sample create mode 100755 tests-clar/resources/template/hooks/pre-applypatch.sample create mode 100755 tests-clar/resources/template/hooks/pre-commit.sample create mode 100755 tests-clar/resources/template/hooks/pre-rebase.sample create mode 100755 tests-clar/resources/template/hooks/prepare-commit-msg.sample create mode 100755 tests-clar/resources/template/hooks/update.sample create mode 100644 tests-clar/resources/template/info/exclude diff --git a/include/git2/config.h b/include/git2/config.h index f415fbd9d..58a23833b 100644 --- a/include/git2/config.h +++ b/include/git2/config.h @@ -90,6 +90,18 @@ GIT_EXTERN(int) git_config_find_system(char *system_config_path, size_t length); */ GIT_EXTERN(int) git_config_open_global(git_config **out); +/** + * Open the global and system configuration files + * + * Utility wrapper that finds the global and system configuration files + * and opens them into a single prioritized config object that can be + * used when accessing config data outside a repository. + * + * @param out Pointer to store the config instance + * @return 0 or an error code + */ +GIT_EXTERN(int) git_config_open_outside_repo(git_config **out); + /** * Create a configuration file backend for ondisk files * diff --git a/include/git2/repository.h b/include/git2/repository.h index afef612c8..a986859d4 100644 --- a/include/git2/repository.h +++ b/include/git2/repository.h @@ -89,8 +89,11 @@ GIT_EXTERN(int) git_repository_discover( * * GIT_REPOSITORY_OPEN_NO_SEARCH - Only open the repository if it can be * immediately found in the start_path.

This also fixes a couple of bugs in the iterators that had not been noticed before - one with iterating when there is a gitlink (i.e. separate-work-dir) and one where I was treating anything even vaguely submodule-like as a submodule, more aggressively than core git does. --- include/git2/diff.h | 15 ++ include/git2/oid.h | 2 + include/git2/submodule.h | 177 ++++++++++---------- src/diff_output.c | 19 +++ src/iterator.c | 21 +-- src/repository.c | 9 +- src/submodule.c | 367 ++++++++++++++++++++--------------------- src/submodule.h | 18 +- tests-clar/status/submodules.c | 8 +- tests-clar/submodule/status.c | 286 ++++++++++++++++++++++++++++++-- 10 files changed, 606 insertions(+), 316 deletions(-) diff --git a/include/git2/diff.h b/include/git2/diff.h index 79ef7a49b..088e1ecfa 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -391,6 +391,21 @@ GIT_EXTERN(int) git_diff_print_patch( void *cb_data, git_diff_data_fn print_cb); +/** + * Query how many diff records are there in a diff list. + * + * You can optionally pass in a `git_delta_t` value if you want a count + * of just entries that match that delta type, or pass -1 for all delta + * records. + * + * @param diff A git_diff_list generated by one of the above functions + * @param delta_t A git_delta_t value to filter the count, or -1 for all records + * @return Count of number of deltas matching delta_t type + */ +GIT_EXTERN(int) git_diff_entrycount( + git_diff_list *diff, + int delta_t); + /**@}*/ diff --git a/include/git2/oid.h b/include/git2/oid.h index 887b33e50..9e54a9f96 100644 --- a/include/git2/oid.h +++ b/include/git2/oid.h @@ -185,6 +185,8 @@ GIT_EXTERN(int) git_oid_streq(const git_oid *a, const char *str); /** * Check is an oid is all zeros. + * + * @return 1 if all zeros, 0 otherwise. */ GIT_EXTERN(int) git_oid_iszero(const git_oid *a); diff --git a/include/git2/submodule.h b/include/git2/submodule.h index 6cd66465e..fe7f26cfe 100644 --- a/include/git2/submodule.h +++ b/include/git2/submodule.h @@ -60,84 +60,68 @@ typedef enum { GIT_SUBMODULE_IGNORE_ALL = 3 /* never dirty */ } git_submodule_ignore_t; -/** - * Status values for submodules. - * - * One of these values will be returned for the submodule in the index - * relative to the HEAD tree, and one will be returned for the submodule in - * the working directory relative to the index.

This ended up being a bit more code change than I had thought since I had to reorganize some of the diff logic to minimize peak memory use when filtering blobs in a diff. This also adds a cap on the maximum size of data that will be loaded to diff. I set it at 512Mb which should match core git.

When this happens, the object is loaded and then disposed of immediately, which makes it difficult to efficiently use the header information to decide if the object should be loaded (since attempting to do so will often result in loading the object twice). This commit takes the existing code and reorganizes it to have two new functions: - `git_odb__read_header_or_object` which acts just like the old read header function except that it returns the object, too, if it was forced to load the whole thing. It then becomes the callers responsibility to free the `git_odb_object`. - `git_object__from_odb_object` which was extracted from the old `git_object_lookup` and creates a subclass of `git_object` from an existing `git_odb_object` (separating the ODB lookup from the `git_object` creation). This allows you to use the first header reading function efficiently without instantiating the `git_odb_object` twice. There is no net change to the behavior of any of the existing functions, but this allows internal code to tap into the ODB lookup and object creation to be more efficient. --- src/diff_output.c | 13 ++++++-- src/object.c | 98 ++++++++++++++++++++++++++++++------------------------- src/object.h | 39 ++++++++++++++++++++++ src/odb.c | 24 ++++++++++++-- src/odb.h | 8 +++++ src/repository.h | 25 ++------------ 6 files changed, 135 insertions(+), 72 deletions(-) create mode 100644 src/object.h diff --git a/src/diff_output.c b/src/diff_output.c index 8873a4dc7..dbef7ddc1 100644 --- a/src/diff_output.c +++ b/src/diff_output.c @@ -292,6 +292,7 @@ static int get_blob_content( git_blob **blob) { int error; + git_odb_object *odb_obj = NULL; if (git_oid_iszero(&file->oid)) return 0; @@ -303,7 +304,8 @@ static int get_blob_content( /* peek at object header to avoid loading if too large */ if ((error = git_repository_odb__weakptr(&odb, ctxt->repo)) < 0 || - (error = git_odb_read_header(&len, &type, odb, &file->oid)) < 0) + (error = git_odb__read_header_or_object( + &odb_obj, &len, &type, odb, &file->oid)) < 0) return error; assert(type == GIT_OBJ_BLOB); @@ -317,7 +319,14 @@ static int get_blob_content( if (ctxt->delta->binary == 1) return 0; - if ((error = git_blob_lookup(blob, ctxt->repo, &file->oid)) < 0) + if (odb_obj != NULL) { + error = git_object__from_odb_object( + (git_object **)blob, ctxt->repo, odb_obj, GIT_OBJ_BLOB); + git_odb_object_free(odb_obj); + } else + error = git_blob_lookup(blob, ctxt->repo, &file->oid); + + if (error) return error; map->data = (void *)git_blob_rawcontent(*blob); diff --git a/src/object.c b/src/object.c index 5130d97ac..2e45eb86a 100644 --- a/src/object.c +++ b/src/object.c @@ -77,6 +77,58 @@ static int create_object(git_object **object_out, git_otype type) return 0; } +int git_object__from_odb_object( + git_object **object_out, + git_repository *repo, + git_odb_object *odb_obj, + git_otype type) +{ + int error; + git_object *object = NULL; + + if (type != GIT_OBJ_ANY && type != odb_obj->raw.type) { + giterr_set(GITERR_ODB, "The requested type does not match the type in the ODB"); + return GIT_ENOTFOUND; + } + + type = odb_obj->raw.type; + + if ((error = create_object(&object, type)) < 0) + return error; + + /* Initialize parent object */ + git_oid_cpy(&object->cached.oid, &odb_obj->cached.oid); + object->repo = repo; + + switch (type) { + case GIT_OBJ_COMMIT: + error = git_commit__parse((git_commit *)object, odb_obj); + break; + + case GIT_OBJ_TREE: + error = git_tree__parse((git_tree *)object, odb_obj); + break; + + case GIT_OBJ_TAG: + error = git_tag__parse((git_tag *)object, odb_obj); + break; + + case GIT_OBJ_BLOB: + error = git_blob__parse((git_blob *)object, odb_obj); + break; + + default: + break; + } + + if (error < 0) + git_object__free(object); + else + *object_out = git_cache_try_store(&repo->objects, object); + + return error; +} + int git_object_lookup_prefix( git_object **object_out, git_repository *repo, @@ -148,53 +200,11 @@ int git_object_lookup_prefix( if (error < 0) return error; - if (type != GIT_OBJ_ANY && type != odb_obj->raw.type) { - git_odb_object_free(odb_obj); - giterr_set(GITERR_ODB, "The given type does not match the type on the ODB"); - return GIT_ENOTFOUND; - } - - type = odb_obj->raw.type; - - if (create_object(&object, type) < 0) { - git_odb_object_free(odb_obj); - return -1; - } - - /* Initialize parent object */ - git_oid_cpy(&object->cached.oid, &odb_obj->cached.oid); - object->repo = repo; - - switch (type) { - case GIT_OBJ_COMMIT: - error = git_commit__parse((git_commit *)object, odb_obj); - break; - - case GIT_OBJ_TREE: - error = git_tree__parse((git_tree *)object, odb_obj); - break; - - case GIT_OBJ_TAG: - error = git_tag__parse((git_tag *)object, odb_obj); - break; - - case GIT_OBJ_BLOB: - error = git_blob__parse((git_blob *)object, odb_obj); - break; - - default: - break; - } + error = git_object__from_odb_object(object_out, repo, odb_obj, type); git_odb_object_free(odb_obj); - if (error < 0) { - git_object__free(object); - return -1; - } - - *object_out = git_cache_try_store(&repo->objects, object); - return 0; + return error; } int git_object_lookup(git_object **object_out, git_repository *repo, const git_oid *id, git_otype type) { diff --git a/src/object.h b/src/object.h new file mode 100644 index 000000000..bc12aad04 --- /dev/null +++ b/src/object.h @@ -0,0 +1,39 @@ +/* + * Copyright (C) 2009-2012 the libgit2 contributors + * + * This file is part of libgit2, distributed under the GNU GPL v2 with + * a Linking Exception.

This causes the ODB to become stale if the directory and packfile are written within the same clock millisecond, as when cloning a fairly small repo. This method tries to find the object in the cached packs, and forces a refresh when that fails. This will cause extra stat'ing on a miss, but speeds up the success case and avoids this race condition. --- src/odb_pack.c | 36 ++++++++++++++++++++++++++++-------- tests-clar/clone/clone.c | 2 +- 2 files changed, 29 insertions(+), 9 deletions(-) diff --git a/src/odb_pack.c b/src/odb_pack.c index b4f958b6f..5d3f0e6e5 100644 --- a/src/odb_pack.c +++ b/src/odb_pack.c @@ -233,10 +233,11 @@ static int packfile_load__cb(void *_data, git_buf *path) return git_vector_insert(&backend->packs, pack);

This is the initial implementation of this revised API - it is still broken, but at least builds cleanly. --- include/git2/diff.h | 62 ++- src/diff.c | 46 +- src/diff.h | 32 +- src/diff_output.c | 1066 +++++++++++++++++++--------------------- src/diff_output.h | 86 ++++ src/submodule.c | 7 +- tests-clar/diff/diff_helpers.c | 75 +-- tests-clar/diff/diffiter.c | 275 ++++++++--- tests-clar/diff/tree.c | 75 +-- tests-clar/diff/workdir.c | 69 +-- 10 files changed, 967 insertions(+), 826 deletions(-) create mode 100644 src/diff_output.h diff --git a/include/git2/diff.h b/include/git2/diff.h index 2a5cdacc0..d216c1303 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -98,6 +98,9 @@ enum { GIT_DIFF_FILE_FREE_PATH = (1 << 1), GIT_DIFF_FILE_BINARY = (1 << 2), GIT_DIFF_FILE_NOT_BINARY = (1 << 3), + GIT_DIFF_FILE_FREE_DATA = (1 << 4), + GIT_DIFF_FILE_UNMAP_DATA = (1 << 5), + GIT_DIFF_FILE_NO_DATA = (1 << 6), }; /** @@ -425,7 +428,7 @@ GIT_EXTERN(int) git_diff_print_patch( * @param diff A git_diff_list generated by one of the above functions * @return Count of number of deltas in the list */ -GIT_EXTERN(size_t) git_diff_entrycount(git_diff_list *diff); +GIT_EXTERN(size_t) git_diff_num_deltas(git_diff_list *diff); /** * Query how many diff deltas are there in a diff list filtered by type. @@ -438,7 +441,7 @@ GIT_EXTERN(size_t) git_diff_entrycount(git_diff_list *diff); * @param type A git_delta_t value to filter the count * @return Count of number of deltas matching delta_t type */ -GIT_EXTERN(size_t) git_diff_entrycount_of_type( +GIT_EXTERN(size_t) git_diff_num_deltas_of_type( git_diff_list *diff, git_delta_t type); @@ -469,7 +472,7 @@ GIT_EXTERN(size_t) git_diff_entrycount_of_type( */ GIT_EXTERN(int) git_diff_get_patch( git_diff_patch **patch, - const git_diff_delta **delta, + git_diff_delta **delta, git_diff_list *diff, size_t idx); @@ -482,43 +485,76 @@ GIT_EXTERN(void) git_diff_patch_free( /** * Get the delta associated with a patch */ -GIT_EXTERN(void) git_diff_patch_get_delta( - const git_diff_delta **delta, +GIT_EXTERN(const git_diff_delta *) git_diff_patch_delta( git_diff_patch *patch); /** * Get the number of hunks in a patch */ -GIT_EXTERN(size_t) git_diff_patch_hunks( +GIT_EXTERN(size_t) git_diff_patch_num_hunks( git_diff_patch *patch); /** * Get the information about a hunk in a patch + * + * Given a patch and a hunk index into the patch, this returns detailed + * information about that hunk.

But core git's status has the notion of a T (typechange) flag for a file. This introduces that into our status APIs and modifies the diff code so it can be forced to not split type changes. --- include/git2/diff.h | 4 +++- include/git2/status.h | 23 +++++++++++++---------- src/diff.c | 26 ++++++++++++++------------ src/status.c | 14 ++++++++++++-- 4 files changed, 42 insertions(+), 25 deletions(-) diff --git a/include/git2/diff.h b/include/git2/diff.h index 121c40307..24556db73 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -49,6 +49,7 @@ enum { GIT_DIFF_DISABLE_PATHSPEC_MATCH = (1 << 11), GIT_DIFF_DELTAS_ARE_ICASE = (1 << 12), GIT_DIFF_INCLUDE_UNTRACKED_CONTENT = (1 << 13), + GIT_DIFF_DONT_SPLIT_TYPECHANGE = (1 << 14), };

v1.2.3 From 0d64bef941928046d114c4da1acb70bd2907855e Mon Sep 17 00:00:00 2001 From: Russell Belfer Date: Fri, 5 Oct 2012 15:56:57 -0700 Subject: Add complex checkout test and then fix checkout This started as a complex new test for checkout going through the "typechanges" test repository, but that revealed numerous issues with checkout, including: * complete failure with submodules * failure to create blobs with exec bits * problems when replacing a tree with a blob because the tree "example/" sorts after the blob "example" so the delete was being processed after the single file blob was created This fixes most of those problems and includes a number of other minor changes that made it easier to do that, including improving the TYPECHANGE support in diff/status, etc. ---

Just as `git_diff_merge` can be used as a post-pass on diffs to emulate certain command line behaviors, there is a new API `git_diff_detect` which will update a diff list in-place, adjusting some deltas to RENAMED or COPIED state (and also, eventually, splitting MODIFIED deltas where the change is too large into DELETED/ADDED pairs). This also adds a new test repo that will hold rename/copy/split scenarios. Right now, it just has exact-match rename and copy, but the tests are written to use tree diffs, so we should be able to add new test scenarios easily without breaking tests. --- include/git2/diff.h | 58 +++++++- src/diff.c | 147 +++++++++++++++++++++ src/diff.h | 3 + tests-clar/diff/blob.c | 76 ++++++----- tests-clar/diff/diff_helpers.c | 17 +-- tests-clar/diff/diff_helpers.h | 9 +- tests-clar/diff/index.c | 12 +- tests-clar/diff/rename.c | 105 +++++++++++++++ tests-clar/diff/tree.c | 50 +++---- tests-clar/diff/workdir.c | 134 +++++++++---------- tests-clar/repo/head.c | 2 - tests-clar/resources/renames/.gitted/HEAD | 1 + tests-clar/resources/renames/.gitted/config | 7 + tests-clar/resources/renames/.gitted/description | 1 + tests-clar/resources/renames/.gitted/index | Bin 0 -> 272 bytes tests-clar/resources/renames/.gitted/info/exclude | 6 + tests-clar/resources/renames/.gitted/logs/HEAD | 2 + .../renames/.gitted/logs/refs/heads/master | 2 + .../03/da7ad872536bd448da8d88eb7165338bf923a7 | Bin 0 -> 90 bytes .../2b/c7f351d20b53f1c72c16c4b036e491c478c49a | Bin 0 -> 173 bytes .../31/e47d8c1fa36d7f8d537b96158e3f024de0a9f2 | Bin 0 -> 131 bytes .../61/8c6f2f8740bd6049b2fb9eb93fc15726462745 | Bin 0 -> 106 bytes .../66/311f5cfbe7836c27510a3ba2f43e282e2c8bba | Bin 0 -> 1155 bytes .../ad/0a8e55a104ac54a8a29ed4b84b49e76837a113 | Bin 0 -> 415 bytes .../resources/renames/.gitted/refs/heads/master | 1 + tests-clar/resources/renames/sevencities.txt | 49 +++++++ tests-clar/resources/renames/sixserving.txt | 24 ++++ tests-clar/resources/renames/songofseven.txt | 49 +++++++ 28 files changed, 589 insertions(+), 166 deletions(-) create mode 100644 tests-clar/diff/rename.c create mode 100644 tests-clar/resources/renames/.gitted/HEAD create mode 100644 tests-clar/resources/renames/.gitted/config create mode 100644 tests-clar/resources/renames/.gitted/description create mode 100644 tests-clar/resources/renames/.gitted/index create mode 100644 tests-clar/resources/renames/.gitted/info/exclude create mode 100644 tests-clar/resources/renames/.gitted/logs/HEAD create mode 100644 tests-clar/resources/renames/.gitted/logs/refs/heads/master create mode 100644 tests-clar/resources/renames/.gitted/objects/03/da7ad872536bd448da8d88eb7165338bf923a7 create mode 100644 tests-clar/resources/renames/.gitted/objects/2b/c7f351d20b53f1c72c16c4b036e491c478c49a create mode 100644 tests-clar/resources/renames/.gitted/objects/31/e47d8c1fa36d7f8d537b96158e3f024de0a9f2 create mode 100644 tests-clar/resources/renames/.gitted/objects/61/8c6f2f8740bd6049b2fb9eb93fc15726462745 create mode 100644 tests-clar/resources/renames/.gitted/objects/66/311f5cfbe7836c27510a3ba2f43e282e2c8bba create mode 100644 tests-clar/resources/renames/.gitted/objects/ad/0a8e55a104ac54a8a29ed4b84b49e76837a113 create mode 100644 tests-clar/resources/renames/.gitted/refs/heads/master create mode 100644 tests-clar/resources/renames/sevencities.txt create mode 100644 tests-clar/resources/renames/sixserving.txt create mode 100644 tests-clar/resources/renames/songofseven.txt diff --git a/include/git2/diff.h b/include/git2/diff.h index 1932db029..f9dbb67e0 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -33,7 +33,7 @@ GIT_BEGIN_DECL * Flags for diff options.

garrisoned with Amazons invincible in war. + +All the world went softly when it walked before my Cities— +Neither King nor Army vexed my peoples at their toil, +Never horse nor chariot irked or overbore my Cities, +Never Mob nor Ruler questioned whence they drew their spoil. + +Banded, mailed and arrogant from sunrise unto sunset; +Singing while they sacked it, they possessed the land at large. +Yet when men would rob them, they resisted, they made onset +And pierced the smoke of battle with a thousand-sabred charge. + +So they warred and trafficked only yesterday, my Cities. +To-day there is no mark or mound of where my Cities stood. +For the River rose at midnight and it washed away my Cities. +They are evened with Atlantis and the towns before the Flood. + +Rain on rain-gorged channels raised the water-levels round them, +Freshet backed on freshet swelled and swept their world from sight, +Till the emboldened floods linked arms and, flashing forward, drowned them— +Drowned my Seven Cities and their peoples in one night! + +Low among the alders lie their derelict foundations, +The beams wherein they trusted and the plinths whereon they built— +My rulers and their

db106d01f093b3e61170e3738d6651a2866cb76e Mon Sep 17 00:00:00 2001 From: Russell Belfer Date: Tue, 30 Oct 2012 09:40:50 -0700 Subject: Move rename detection into new file This improves the naming for the rename related functionality moving it to be called `git_diff_find_similar()` and renaming all the associated constants, etc. to make more sense. I also moved the new code (plus the existing `git_diff_merge`) into a new file `diff_tform.c` where I can put new functions related to manipulating git diff lists. This also updates the implementation significantly from the last revision fixing some ordering issues (where break-rewrite needs to be handled prior to copy and rename detection) and improving config option handling. --- include/git2/diff.h | 48 +++-- src/diff.c | 342 +++------------------------------- src/diff.h | 2 + src/diff_tform.c | 466 +++++++++++++++++++++++++++++++++++++++++++++++ src/vector.c | 30 +++ src/vector.h | 3 + tests-clar/diff/rename.c | 10 +- 7 files changed, 559 insertions(+), 342 deletions(-) create mode 100644 src/diff_tform.c diff --git a/include/git2/diff.h b/include/git2/diff.h index f9dbb67e0..439215575 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -263,31 +263,41 @@ typedef struct git_diff_patch git_diff_patch; * Flags to control the behavior of diff rename/copy detection. */ typedef enum { - /** should we look for renames */ - GIT_DIFF_DETECT_RENAMES = (1 << 0), - /** should we look for copies */ - GIT_DIFF_DETECT_COPIES = (1 << 1), - /** should we consider unmodified files as possible copy sources */ - GIT_DIFF_DETECT_COPIES_FROM_UNMODIFIED = (1 << 2), - /** should we split large rewrites into delete / add pairs */ - GIT_DIFF_DETECT_BREAK_REWRITES = (1 << 3), -} git_diff_detect_t; + /** look for renames?

A new config callback function to refresh the config was added. The modified time and file size are used to test if the file needs to be reloaded (and are now stored in the disk backend object). In writing tests, just using mtime was a problem / race, so I wanted to check file size as well. To support that, I extended `git_futils_readbuffer_updated` to optionally check file size in addition to mtime, and I added a new function `git_filebuf_stats` to fetch the mtime and size for an open filebuf (so that the config could be easily refreshed after a write). Lastly, I moved some similar file checking code for attributes into filebuf. It is still only being used for attrs, but it seems potentially reusable, so I thought I'd move it over. --- include/git2/config.h | 14 ++++++++++ src/attr.c | 34 ++++++++++------------- src/attr_file.h | 9 ++---- src/config.c | 14 ++++++++++ src/config_file.c | 49 +++++++++++++++++++++++++++++---- src/filebuf.c | 23 ++++++++++++++++ src/filebuf.h | 1 + src/fileops.c | 45 ++++++++++++++++++++++++++---- src/fileops.h | 25 ++++++++++++++++- src/index.c | 2 +- src/refs.c | 3 +- tests-clar/config/refresh.c | 67 +++++++++++++++++++++++++++++++++++++++++++++ 12 files changed, 245 insertions(+), 41 deletions(-) create mode 100644 tests-clar/config/refresh.c diff --git a/include/git2/config.h b/include/git2/config.h index 67408f90f..e417cb379 100644 --- a/include/git2/config.h +++ b/include/git2/config.h @@ -56,6 +56,7 @@ struct git_config_file { int (*set_multivar)(git_config_file *cfg, const char *name, const char *regexp, const char *value); int (*del)(struct git_config_file *, const char *key); int (*foreach)(struct git_config_file *, const char *, int (*fn)(const git_config_entry *, void *), void *data); + int (*refresh)(struct git_config_file *); void (*free)(struct git_config_file *); }; @@ -242,6 +243,19 @@ GIT_EXTERN(int) git_config_open_level( git_config *cfg_parent, unsigned int level); +/** + * Reload changed config files + * + * A config file may be changed on disk out from under the in-memory + * config object.

If checkout is given only a very limited strategy mask (e.g. just GIT_CHECKOUT_CREATE_MISSING) then it is possible for typechange/rename modifications to leave it unable to complete the request. That's okay, but the existing code did not have enough information not to generate an error (at least for tree/blob conflicts). This led me to a significant reorganization of the code to handle the failing case, but it has three benefits: 1. The test case is handled correctly (I think) 2. The new code should actually be much faster than the old code since I decided to make checkout aware of diff list internals. 3. The progress value accuracy is hugely increased since I added a fourth pass which calculates exactly what work needs to be done before doing anything. --- src/checkout.c | 349 +++++++++++++++++++++++++++++--------------- tests-clar/checkout/index.c | 33 ++++- 2 files changed, 262 insertions(+), 120 deletions(-) diff --git a/src/checkout.c b/src/checkout.c index b9a5399cc..e4a397cd5 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -21,6 +21,7 @@ #include "repository.h" #include "filter.h" #include "blob.h" +#include "diff.h" struct checkout_diff_data { @@ -43,20 +44,23 @@ static int buffer_to_file( int file_open_flags, mode_t file_mode) { - int fd, error, error_close; + int fd, error; if ((error = git_futils_mkpath2file(path, dir_mode)) < 0) return error; - if ((fd = p_open(path, file_open_flags, file_mode)) < 0) + if ((fd = p_open(path, file_open_flags, file_mode)) < 0) { + giterr_set(GITERR_OS, "Could not open '%s' for writing", path); return fd; + } - error = p_write(fd, git_buf_cstr(buffer), git_buf_len(buffer)); - - error_close = p_close(fd); - - if (!error) - error = error_close; + if ((error = p_write(fd, git_buf_cstr(buffer), git_buf_len(buffer))) < 0) { + giterr_set(GITERR_OS, "Could not write to '%s'", path); + (void)p_close(fd); + } else { + if ((error = p_close(fd)) < 0) + giterr_set(GITERR_OS, "Error while closing '%s'", path); + } if (!error && (file_mode & 0100) != 0 && @@ -160,8 +164,8 @@ static int checkout_submodule( } static void report_progress( - struct checkout_diff_data *data, - const char *path) + struct checkout_diff_data *data, + const char *path) { if (data->checkout_opts->progress_cb) data->checkout_opts->progress_cb( @@ -176,12 +180,19 @@ static int checkout_blob( const git_diff_file *file) { git_blob *blob; - int error; + int error = 0; git_buf_truncate(data->path, data->workdir_len); if (git_buf_joinpath(data->path, git_buf_cstr(data->path), file->path) < 0) return -1; + /* If there is a directory where this blob should go, then there is an + * existing tree that conflicts with this file, but REMOVE_UNTRACKED must + * not have been passed in.

This contains three main things: 1. Share the function diff uses to calculate the OID for a file in the working directory (now named `git_diff__oid_for_file` 2. Add a `git_diff__paired_foreach` function to iterator over two diff lists concurrently. Convert status to use it. 3. Move all the string/prefix/index entry comparisons into function pointers inside the `git_diff_list` object so they can be switched between case sensitive and insensitive versions. This makes them easier to reuse in various functions without replicating logic. As part of this, move a couple of index functions out of diff.c and into index.c. --- src/attr_file.h | 1 + src/diff.c | 166 ++++++++++++++++++++++++++++++------------------------ src/diff.h | 8 +++ src/diff_output.c | 55 ++++++++++++++++++ src/diff_output.h | 6 ++ src/index.c | 20 ++++++- src/index.h | 5 +- src/iterator.c | 2 +- src/status.c | 83 ++++++++++++--------------- src/submodule.c | 2 +- src/util.h | 5 ++ 11 files changed, 226 insertions(+), 127 deletions(-) diff --git a/src/attr_file.h b/src/attr_file.h index 3ea13d273..5bdfc7054 100644 --- a/src/attr_file.h +++ b/src/attr_file.h @@ -7,6 +7,7 @@ #ifndef INCLUDE_attr_file_h__ #define INCLUDE_attr_file_h__ +#include "git2/oid.h" #include "git2/attr.h" #include "vector.h" #include "pool.h" diff --git a/src/diff.c b/src/diff.c index f3dfdd9dc..015c77edd 100644 --- a/src/diff.c +++ b/src/diff.c @@ -327,24 +327,39 @@ void git_diff_list_addref(git_diff_list *diff) GIT_REFCOUNT_INC(diff);

The checkout code is now sensitive to the contents of the HEAD tree and the new options allow you to update the working tree so that it will match the index content only when it previously matched the contents of the HEAD. This allows you to, for example, to distinguish between removing files that are in the HEAD but not in the index, vs just removing all untracked files. Because of various corner cases that arise, etc., this required some additional capabilities in rmdir and other utility functions. This includes the beginnings of an implementation of code to read a partial tree into the index based on a pathspec, but that is not enabled because of the possibility of creating conflicting index entries. --- include/git2/checkout.h | 155 ++++++++++--- include/git2/errors.h | 1 + src/checkout.c | 466 ++++++++++++++++++++++++++------------- src/fileops.c | 48 +++- src/fileops.h | 2 + src/index.c | 53 +++++ src/index.h | 3 + src/path.c | 5 +- src/reset.c | 5 +- src/stash.c | 4 +- tests-clar/checkout/index.c | 74 ++++--- tests-clar/checkout/tree.c | 5 +- tests-clar/checkout/typechange.c | 13 +- tests-clar/clone/network.c | 2 +- 14 files changed, 610 insertions(+), 226 deletions(-) diff --git a/include/git2/checkout.h b/include/git2/checkout.h index 390d2f215..a9314c2cb 100644 --- a/include/git2/checkout.h +++ b/include/git2/checkout.h @@ -25,20 +25,117 @@ GIT_BEGIN_DECL * Checkout behavior flags * * These flags control what checkout does with files.

The Visual Studio IDE automatically inserts this dependency when it sees the right combination of "/Y" parameters.

This makes it more robust at ignoring .git files. This also makes iterators always check ".git" case insensitively regardless of the properties of the system. This will make libgit2 skip ".GIT" and the like. This is different from core git, but on systems with case insensitive but case preserving file systems, allowing ".GIT" to be added is problematic. --- src/iterator.c | 27 ++++++++++++++++++---- tests-clar/diff/iterator.c | 56 ++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 79 insertions(+), 4 deletions(-) diff --git a/src/iterator.c b/src/iterator.c index ee83a4fda..75985355f 100644 --- a/src/iterator.c +++ b/src/iterator.c @@ -10,6 +10,7 @@ #include "ignore.h" #include "buffer.h" #include "git2/submodule.h" +#include #define ITERATOR_BASE_INIT(P,NAME_LC,NAME_UC) do { \ (P) = git__calloc(1, sizeof(NAME_LC ## _iterator)); \ @@ -465,6 +466,23 @@ static int git_path_with_stat_cmp_icase(const void *a, const void *b) return strcasecmp(path_with_stat_a->path, path_with_stat_b->path); } +GIT_INLINE(bool) path_is_dotgit(const git_path_with_stat *ps) +{ + if (!ps) + return false; + else { + const char *path = ps->path; + size_t len = ps->path_len; + + return len >= 4 && + tolower(path[len - 1]) == 't' && + tolower(path[len - 2]) == 'i' && + tolower(path[len - 3]) == 'g' && + path[len - 4] == '.' && + (len == 4 || path[len - 5] == '/'); + } +} + static workdir_iterator_frame *workdir_iterator__alloc_frame(workdir_iterator *wi) { workdir_iterator_frame *wf = git__calloc(1, sizeof(workdir_iterator_frame)); @@ -531,6 +549,9 @@ static int workdir_iterator__expand_dir(workdir_iterator *wi) CASESELECT(wi->base.ignore_case, workdir_iterator__entry_cmp_icase, workdir_iterator__entry_cmp_case), wf->start); + if (path_is_dotgit(git_vector_get(&wf->entries, wf->index))) + wf->index++; + wf->next = wi->stack; wi->stack = wf; @@ -574,8 +595,7 @@ static int workdir_iterator__advance( next = git_vector_get(&wf->entries, ++wf->index); if (next != NULL) { /* match git's behavior of ignoring anything named ".git" */ - if (STRCMP_CASESELECT(wi->base.ignore_case, next->path, DOT_GIT "/") == 0 || - STRCMP_CASESELECT(wi->base.ignore_case, next->path, DOT_GIT) == 0) + if (path_is_dotgit(next)) continue; /* else found a good entry */ break; @@ -658,8 +678,7 @@ static int workdir_iterator__update_entry(workdir_iterator *wi) wi->entry.path = ps->path; /* skip over .git entries */ - if (STRCMP_CASESELECT(wi->base.ignore_case, ps->path, DOT_GIT "/") == 0 || - STRCMP_CASESELECT(wi->base.ignore_case, ps->path, DOT_GIT) == 0) + if (path_is_dotgit(ps)) return workdir_iterator__advance((git_iterator *)wi, NULL); wi->is_ignored = -1; diff --git a/tests-clar/diff/iterator.c b/tests-clar/diff/iterator.c index 368903200..1d8396099 100644 --- a/tests-clar/diff/iterator.c +++ b/tests-clar/diff/iterator.c @@ -668,3 +668,59 @@ void test_diff_iterator__workdir_1_ranged_empty_2(void) "status", NULL, "aaaa_empty_before", 0, 0, NULL, NULL); } + +void test_diff_iterator__workdir_builtin_ignores(void) +{ + git_repository *repo = cl_git_sandbox_init("attr"); + git_iterator *i; + const git_index_entry *entry; + int idx; + static struct { + const char *path; + bool ignored; + } expected[] = { + { "dir/", true }, + { "file", false }, + { "ign", true }, + { "macro_bad", false }, + { "macro_test", false }, + { "root_test1", false }, + { "root_test2", false }, + { "root_test3", false }, + { "root_test4.txt", false }, + { "sub/", false }, + { "sub/.gitattributes", false }, + { "sub/abc", false }, + { "sub/dir/", true }, + { "sub/file", false }, + { "sub/ign/", true }, + { "sub/sub/", false }, + { "sub/sub/.gitattributes", false }, + { "sub/sub/dir", false }, /* file is not actually a dir */ + { "sub/sub/file", false }, + { NULL, false } + }; + + cl_git_pass(p_mkdir("attr/sub/sub/.git", 0777)); + cl_git_mkfile("attr/sub/.git", "whatever"); + + cl_git_pass( + git_iterator_for_workdir_range(&i, repo, "dir", "sub/sub/file")); + cl_git_pass(git_iterator_current(i, &entry)); + + for (idx = 0; entry != NULL; ++idx) { + int ignored = git_iterator_current_is_ignored(i); + + cl_assert_equal_s(expected[idx].path, entry->path); + cl_assert_(ignored == expected[idx].ignored, expected[idx].path); + + if (!ignored && S_ISDIR(entry->mode)) + cl_git_pass(git_iterator_advance_into_directory(i, &entry)); + else + cl_git_pass(git_iterator_advance(i, &entry)); + } + + cl_assert(expected[idx].path == NULL); + + git_iterator_free(i); +} -- cgit v1.2.3 From 2d96fce20b5ab0dd04d66165be6e067312ff19e6 Mon Sep 17 00:00:00 2001 From: Eduardo Bart Date: Mon, 19 Nov 2012 23:12:20 -0200 Subject: update win32 lstat comment --- src/win32/posix_w32.c | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/src/win32/posix_w32.c b/src/win32/posix_w32.c index 06da7ca95..d0e366e28 100644 --- a/src/win32/posix_w32.c +++ b/src/win32/posix_w32.c @@ -106,12 +106,9 @@ static int do_lstat( errno = ENOENT; - /* ERROR_PATH_NOT_FOUND can mean either that a parent directory is - * missing or that an expected directory is a regular file.

There are still some index and tree APIs that cannot take const pointers because we sort our `git_vectors` lazily and so we can't reliably bsearch the index and tree content without applying a `git_vector_sort()` first. This also fixes some missed places where size_t can be used and where const can be applied to a couple internal functions. --- include/git2/index.h | 10 ++++++---- include/git2/tree.h | 17 +++++++---------- src/index.c | 38 ++++++++++++++++++++------------------ src/index.h | 2 +- src/iterator.c | 8 +++++--- src/tree.c | 33 +++++++++++++++++++-------------- src/tree.h | 3 ++- src/util.c | 2 +- src/vector.c | 35 ++++++++++++++++++----------------- src/vector.h | 20 ++++++++------------ tests-clar/core/vector.c | 2 +- 11 files changed, 88 insertions(+), 82 deletions(-) diff --git a/include/git2/index.h b/include/git2/index.h index 195e5b13f..9d1fd17d0 100644 --- a/include/git2/index.h +++ b/include/git2/index.h @@ -258,7 +258,7 @@ GIT_EXTERN(int) git_index_write_tree_to(git_oid *out, git_index *index, git_repo * @param index an existing index object * @return integer of count of current entries */ -GIT_EXTERN(unsigned int) git_index_entrycount(git_index *index); +GIT_EXTERN(unsigned int) git_index_entrycount(const git_index *index); /** * Clear the contents (all the entries) of an index object. @@ -282,7 +282,8 @@ GIT_EXTERN(void) git_index_clear(git_index *index); * @param n the position of the entry * @return a pointer to the entry; NULL if out of bounds */ -GIT_EXTERN(const git_index_entry *) git_index_get_byindex(git_index *index, size_t n); +GIT_EXTERN(const git_index_entry *) git_index_get_byindex( + git_index *index, size_t n); /** * Get a pointer to one of the entries in the index @@ -298,7 +299,8 @@ GIT_EXTERN(const git_index_entry *) git_index_get_byindex(git_index *index, size * @param stage stage to search * @return a pointer to the entry; NULL if it was not found */ -GIT_EXTERN(const git_index_entry *) git_index_get_bypath(git_index *index, const char *path, int stage); +GIT_EXTERN(const git_index_entry *) git_index_get_bypath( + git_index *index, const char *path, int stage); /** * Remove an entry from the index @@ -443,7 +445,7 @@ GIT_EXTERN(void) git_index_conflict_cleanup(git_index *index); * * @return 1 if at least one conflict is found, 0 otherwise. */ -GIT_EXTERN(int) git_index_has_conflicts(git_index *index); +GIT_EXTERN(int) git_index_has_conflicts(const git_index *index); /**@}*/ diff --git a/include/git2/tree.h b/include/git2/tree.h index 0104ba144..2d3534fab 100644 --- a/include/git2/tree.h +++ b/include/git2/tree.h @@ -127,7 +127,7 @@ GIT_EXTERN(const git_tree_entry *) git_tree_entry_byindex( * @return the tree entry; NULL if not found */ GIT_EXTERN(const git_tree_entry *) git_tree_entry_byoid( - git_tree *tree, const git_oid *oid); + const git_tree *tree, const git_oid *oid); /** * Retrieve a tree entry contained in a tree or in any of its subtrees, @@ -351,18 +351,15 @@ typedef enum { } git_treewalk_mode; /** - * Traverse the entries in a tree and its subtrees in - * post or pre order + * Traverse the entries in a tree and its subtrees in post or pre order. * - * The entries will be traversed in the specified order, - * children subtrees will be automatically loaded as required, - * and the `callback` will be called once per entry with - * the current (relative) root for the entry and the entry - * data itself. + * The entries will be traversed in the specified order, children subtrees + * will be automatically loaded as required, and the `callback` will be + * called once per entry with the current (relative) root for the entry and + * the entry data itself. * * If the callback returns a positive value, the passed entry will be - * skipped on the traversal (in pre mode).

Nov 2012 09:58:48 -0800 Subject: Consolidate text buffer functions There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM). --- src/buf_text.c | 208 ++++++++++++++++++++++++++++++++++++++++ src/buf_text.h | 100 +++++++++++++++++++ src/buffer.c | 114 ++-------------------- src/buffer.h | 56 ++++------- src/config.c | 3 +- src/config_file.c | 16 ++-- src/crlf.c | 13 +-- src/diff_output.c | 2 +- src/filter.c | 69 ------------- src/filter.h | 29 +----- src/path.c | 2 +- src/pathspec.c | 5 +- src/submodule.c | 3 +- tests-clar/core/buffer.c | 25 ++--- tests-clar/object/blob/filter.c | 32 ++++--- 15 files changed, 388 insertions(+), 289 deletions(-) create mode 100644 src/buf_text.c create mode 100644 src/buf_text.h diff --git a/src/buf_text.c b/src/buf_text.c new file mode 100644 index 000000000..3c5024e6c --- /dev/null +++ b/src/buf_text.c @@ -0,0 +1,208 @@ +/* + * Copyright (C) 2009-2012 the libgit2 contributors + * + * This file is part of libgit2, distributed under the GNU GPL v2 with + * a Linking Exception.

It reduces the memory needs in some cases, but delta objects still need to be completely in memory and the old inefficent method is still used for that. --- src/indexer.c | 157 ++++++++++++++++++++++++++++++++++++++++++++++++---------- src/odb.c | 6 +-- src/odb.h | 4 ++ 3 files changed, 137 insertions(+), 30 deletions(-) diff --git a/src/indexer.c b/src/indexer.c index a51d903ed..c331a4483 100644 --- a/src/indexer.c +++ b/src/indexer.c @@ -38,15 +38,19 @@ struct git_indexer { struct git_indexer_stream { unsigned int parsed_header :1, - opened_pack;

Adjust the logic so we read them as they come, just as we do for full objects. This also allows us to simplify the logic and have less nested code. The delta resolving phase still needs to decompress the whole object into memory, as there is not yet any streaming delta-apply support, but it helps in speeding up the downloading process and reduces the amount of memory allocations we need to do. --- src/indexer.c | 127 ++++++++++++++++++++++++++++++++++++---------------------- 1 file changed, 78 insertions(+), 49 deletions(-) diff --git a/src/indexer.c b/src/indexer.c index c331a4483..726667665 100644 --- a/src/indexer.c +++ b/src/indexer.c @@ -39,7 +39,8 @@ struct git_indexer { struct git_indexer_stream { unsigned int parsed_header :1, opened_pack :1, - have_stream :1;

If you have: * An object that is not a delta; both type and size are available in the packfile header. * An object that is a delta. The packfile type will be OBJ_*_DELTA, and you have to resolve back to the base to find the real type. That means potentially a lot of packfile index lookups, but each one is relatively cheap. For the size, you inflate the first few bytes of the delta, whose header will tell you the resulting size of applying the delta to the base. For simplicity, we just decompress the whole delta for now. --- src/pack.c | 50 ++++++++++++++++++++++++++++++++++++++++++++++++++ src/pack.h | 6 ++++++ 2 files changed, 56 insertions(+) diff --git a/src/pack.c b/src/pack.c index 6cb46d37b..d7d39392f 100644 --- a/src/pack.c +++ b/src/pack.c @@ -277,6 +277,56 @@ int git_packfile_unpack_header( return 0; } +int git_packfile_resolve_header( + size_t *size_p, + git_otype *type_p, + struct git_pack_file *p, + git_off_t offset) +{ + git_mwindow *w_curs = NULL; + git_off_t curpos = offset; + size_t size; + git_otype type; + git_off_t base_offset; + int error; + + error = git_packfile_unpack_header(&size, &type, &p->mwf, &w_curs, &curpos); + git_mwindow_close(&w_curs); + if (error < 0) + return error; + + if (type == GIT_OBJ_OFS_DELTA || type == GIT_OBJ_REF_DELTA) { + size_t base_size; + git_rawobj delta; + base_offset = get_delta_base(p, &w_curs, &curpos, type, offset); + git_mwindow_close(&w_curs); + error = packfile_unpack_compressed(&delta, p, &w_curs, &curpos, size, type); + git_mwindow_close(&w_curs); + if (error < 0) + return error; + error = git__delta_read_header(delta.data, delta.len, &base_size, size_p); + git__free(delta.data); + if (error < 0) + return error; + } else + *size_p = size; + + while (type == GIT_OBJ_OFS_DELTA || type == GIT_OBJ_REF_DELTA) { + curpos = base_offset; + error = git_packfile_unpack_header(&size, &type, &p->mwf, &w_curs, &curpos); + git_mwindow_close(&w_curs); + if (error < 0) + return error; + if (type != GIT_OBJ_OFS_DELTA && type != GIT_OBJ_REF_DELTA) + break; + base_offset = get_delta_base(p, &w_curs, &curpos, type, base_offset); + git_mwindow_close(&w_curs); + } + *type_p = type; + + return error; +} + static int packfile_unpack_delta( git_rawobj *obj, struct git_pack_file *p, diff --git a/src/pack.h b/src/pack.h index 9fb26b6a9..c1277fdfb 100644 --- a/src/pack.h +++ b/src/pack.h @@ -83,6 +83,12 @@ int git_packfile_unpack_header( git_mwindow **w_curs, git_off_t *curpos); +int git_packfile_resolve_header( + size_t *size_p, + git_otype *type_p, + struct git_pack_file *p, + git_off_t offset); + int git_packfile_unpack(git_rawobj *obj, struct git_pack_file *p, git_off_t *obj_offset); int packfile_unpack_compressed( git_rawobj *obj, -- cgit v1.2.3 From bfb8bcc1df18431e8e7cf2a9dce8acc95cd312e3 Mon Sep 17 00:00:00 2001 From: David Michael Barr Date: Mon, 3 Dec 2012 10:36:32 +1100 Subject: odb-pack: resurrect pack_backend__read_header --- src/odb_pack.c | 19 +++++++++---------- 1 file changed, 9 insertions(+), 10 deletions(-) diff --git a/src/odb_pack.c b/src/odb_pack.c index 35bf1580d..fc282dd14 100644 --- a/src/odb_pack.c +++ b/src/odb_pack.c @@ -384,19 +384,18 @@ cleanup: * ***********************************************************/ -/* -int pack_backend__read_header(git_rawobj *obj, git_odb_backend *backend, const git_oid *oid) +static int pack_backend__read_header(size_t *len_p, git_otype *type_p, struct git_odb_backend *backend, const git_oid *oid) { - pack_location location; + struct git_pack_entry e; + int error; - assert(obj && backend && oid); + assert(len_p && type_p && backend && oid); - if (locate_packfile(&location, (struct pack_backend *)backend, oid) < 0) - return GIT_ENOTFOUND; + if ((error = pack_entry_find(&e, (struct pack_backend *)backend, oid)) < 0) + return error; - return read_header_packed(obj, &location); + return git_packfile_resolve_header(len_p, type_p, e.p, e.offset); } -*/ static int pack_backend__read(void **buffer_p, size_t *len_p, git_otype *type_p, git_odb_backend *backend, const git_oid *oid) { @@ -579,7 +578,7 @@ int git_odb_backend_one_pack(git_odb_backend **backend_out, const char *idx) backend->parent.read = &pack_backend__read; backend->parent.read_prefix = &pack_backend__read_prefix; - backend->parent.read_header = NULL; + backend->parent.read_header = &pack_backend__read_header; backend->parent.exists = &pack_backend__exists; backend->parent.foreach = &pack_backend__foreach; backend->parent.free = &pack_backend__free; @@ -616,7 +615,7 @@ int git_odb_backend_pack(git_odb_backend **backend_out, const char *objects_dir) backend->parent.read = &pack_backend__read; backend->parent.read_prefix = &pack_backend__read_prefix; - backend->parent.read_header = NULL; + backend->parent.read_header = &pack_backend__read_header; backend->parent.exists = &pack_backend__exists; backend->parent.foreach = &pack_backend__foreach; backend->parent.writepack = &pack_backend__writepack; -- cgit v1.2.3 From 7ea3a79f0cc157980cbc0c4117f2458cc535a0d8 Mon Sep 17 00:00:00 2001 From: Vicent Marti Date: Mon, 3 Dec 2012 16:04:39 +0100 Subject: Vade retro satana --- src/config_cache.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/config_cache.c b/src/config_cache.c index ca9602e56..244202351 100644 --- a/src/config_cache.c +++ b/src/config_cache.c @@ -24,7 +24,7 @@ struct map_data { * core.eol * Sets the line ending type to use in the working directory for * files that have the text property set.

Goldman" Date: Sun, 9 Dec 2012 21:24:47 -0800 Subject: Fix mark_parents() to account for bad luck traversals If commit timestamps are off, we're more likely to hit a traversal where the first path ends up traversing past the root commit of the tree. If that happens, it's possible that the loop will complete before the second path marks some of those final parents. This fix keeps track of the root nodes that are encountered in the traversal, and verify that they are properly marked. In the best case, with accurate timestamps, the traversal will continue to terminate when all the commits are STALE (parents of a merge-base), as it did before. In the worst case, where one path makes a complete traversal past a root commit, we will continue the loop until the root commit itself is marked. --- src/graph.c | 20 ++++++++++++++++++-- 1 file changed, 18 insertions(+), 2 deletions(-) diff --git a/src/graph.c b/src/graph.c index ee4fee72d..2fc50ea6e 100644 --- a/src/graph.c +++ b/src/graph.c @@ -10,7 +10,7 @@ #include "merge.h" #include "git2/graph.h" -static int interesting(git_pqueue *list) +static int interesting(git_pqueue *list, git_commit_list *roots) { unsigned int i; /* element 0 isn't used - we need to start at 1 */ @@ -20,6 +20,12 @@ static int interesting(git_pqueue *list) return 1; } + while(roots) { + if ((roots->item->flags & STALE) == 0) + return 1; + roots = roots->next; + } + return 0; } @@ -28,6 +34,7 @@ static int mark_parents(git_revwalk *walk, git_commit_list_node *one, { int error; unsigned int i; + git_commit_list *roots = NULL; git_pqueue list; /* if the commit is repeated, we have a our merge base already */ @@ -52,11 +59,13 @@ static int mark_parents(git_revwalk *walk, git_commit_list_node *one, return -1; /* as long as there are non-STALE commits */ - while (interesting(&list)) { + while (interesting(&list, roots)) { git_commit_list_node *commit; int flags; commit = git_pqueue_pop(&list); + if (commit == NULL) + break; flags = commit->flags & (PARENT1 | PARENT2 | STALE); if (flags == (PARENT1 | PARENT2)) { @@ -78,8 +87,15 @@ static int mark_parents(git_revwalk *walk, git_commit_list_node *one, if (git_pqueue_insert(&list, p) < 0) return -1; } + + if (commit->out_degree == 0) { + if (git_commit_list_insert(commit, &roots) == NULL) + return -1; + } } + if (roots) + git_commit_list_free(&roots); git_pqueue_free(&list); return 0; -- cgit v1.2.3 From 7d26c410bf6f5ba3be18c60d789d064219f9aca6 Mon Sep 17 00:00:00 2001 From: "Scott J.

One proposal changes all iterator APIs to use git_iterator** so we can reallocate the iterator at will, but that seems unexpected. This commit makes it so that an iterator can be changed in place. The callbacks are isolated in a separate structure and a pointer to that structure can be reassigned by the spoolandsort extension. This means that spoolandsort doesn't create a new iterator; it just allocates a new block of callbacks (along with space for its own extra data) and swaps that into the iterator. Additionally, since spoolandsort is only needed to switch the case sensitivity of an iterator, this simplifies the API to only take the ignore_case boolean and to be a no-op if the iterator already matches the requested case sensitivity. --- src/checkout.c | 4 +- src/diff.c | 19 ++---- src/iterator.c | 206 +++++++++++++++++++++++++++++++++------------------------ src/iterator.h | 46 ++++++------- 4 files changed, 148 insertions(+), 127 deletions(-) diff --git a/src/checkout.c b/src/checkout.c index 972366fbb..66eb698ab 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -452,9 +452,7 @@ static int checkout_get_actions( goto fail; if ((diff->opts.flags & GIT_DIFF_DELTAS_ARE_ICASE) != 0 && - !hiter->ignore_case && - (error = git_iterator_spoolandsort( - &hiter, hiter, diff->entrycomp, true)) < 0) + (error = git_iterator_spoolandsort_push(hiter, true)) < 0) goto fail; if ((error = git_iterator_current(hiter, &he)) < 0) diff --git a/src/diff.c b/src/diff.c index 9c0b45f8e..83e73cd03 100644 --- a/src/diff.c +++ b/src/diff.c @@ -589,18 +589,13 @@ int git_diff__from_iterators( goto fail; if (diff->opts.flags & GIT_DIFF_DELTAS_ARE_ICASE) { - /* If one of the iterators doesn't have ignore_case set, - * then that's unfortunate because we'll have to spool - * its data, sort it icase, and then use that for our - * merge join to the other iterator that is icase sorted */ - if (!old_iter->ignore_case && - git_iterator_spoolandsort( - &old_iter, old_iter, diff->entrycomp, true) < 0) - goto fail; - - if (!new_iter->ignore_case && - git_iterator_spoolandsort( - &new_iter, new_iter, diff->entrycomp, true) < 0) + /* If either iterator does not have ignore_case set, then we will + * spool its data, sort it icase, and use that for the merge join + * with the other iterator which was icase sorted.

This allows us to use the HEAD and the index content to know what files can / should safely be reset. Unfortunately, there are still some cases where the behavior of this revision differs from core git. Notable, a file which has been added to the index but is not present in the HEAD is considered to be tracked by core git (and thus removable by a reset command) whereas since this loads the target state into the index prior to resetting, it will consider such a file to be untracked and won't touch it.

I've thrown away flags in the checkout API that seemed like clutter and added some new ones. Also, I've converted the conflict callback to a general notification callback so we can emulate "git checkout" output and display "dirty" files. As of this commit, the new behavior is not working 100% but some of that is probably baked into tests that are not testing the right thing.

See notes below on + * emulating `git checkout-index` for some of the subtleties of this. + * + * - `GIT_CHECKOUT_FORCE` is like `git checkout -f` and will update the + * working directory to match the target content regardless of conflicts, + * overwriting dirty and conflicting files. + * + * + * There are some additional flags to modified the behavior of checkout: + * + * - GIT_CHECKOUT_ALLOW_CONFLICTS can be added to apply safe file updates + * even if there are conflicts. Normally, the entire checkout will be + * cancelled if any files are in category 4. With this flag, conflicts + * will be skipped (though the notification callback will still be invoked + * on the conflicting files if requested). + * + * - GIT_CHECKOUT_REMOVE_UNTRACKED means that files in the working directory + * that are untracked (but not ignored) should be deleted. The are not + * considered conflicts and would normally be ignored by checkout. + * + * - GIT_CHECKOUT_REMOVE_IGNORED means to remove ignored files from the + * working directory as well. Obviously, these would normally be ignored. + * + * - GIT_CHECKOUT_UPDATE_ONLY means to only update the content of files that + * already exist. Files will not be created nor deleted. This does not + * make adds and deletes into conflicts - it just skips applying those + * changes. This will also skip updates to typechanged files (since that + * would involve deleting the old and creating the new). + * + * - Unmerged entries in the index are also considered conflicts. The + * GIT_CHECKOUT_SKIP_UNMERGED flag causes us to skip files with unmerged + * index entries. You can also use GIT_CHECKOUT_USE_OURS and + * GIT_CHECKOUT_USE_THEIRS to proceeed with the checkout using either the + * stage 2 ("ours") or stage 3 ("theirs") version of files in the index. + * + * + * To emulate `git checkout`, use `GIT_CHECKOUT_SAFE` with a checkout + * notification callback (see below) that displays information about dirty + * files (i.e. files that don't need an update but that no longer match the + * expected content). The default behavior will cancel on conflicts. + * + * To emulate `git checkout-index`, use `GIT_CHECKOUT_SAFE_CREATE` with a + * notification callback that cancels the operation if a dirty-but-existing + * file is found in the working directory.

This updates stash to preserve the original error code more reliably along with a variety of other error handling tweaks. I believe this is an improvement, but arguably, preserving the underlying error code may result in values that are harder to interpret by the caller who does not understand the internals.

UNTRACKED/IGNORED - Files in the working directory that are untracked + or ignored (i.e. only in the working directory, not the other places). + +Right now, this classification is done via 3 iterators (for the three +trees), with a final lookup in the index. At some point, this may move to +a 4 iterator version to incorporate the index better. + +The actual checkout is done in five phases (at least right now). + +1.

One is with untracked working directory entries that are prefixes of tree entries but not in a meaningful way (i.e. "read" is a prefix of "readme.txt" but doesn't interfere in any way). The second bug is actually a redo of 07edfa0fc640f85f95507c3101e77accd7d2bf0d where directory entries in the index that are not in the diff were not being removed correctly. That fix remedied one case but broke another. --- src/checkout.c | 69 +++++++++++++++++++++++++++------------------ tests-clar/checkout/index.c | 25 ++++++++++++++++ 2 files changed, 66 insertions(+), 28 deletions(-) diff --git a/src/checkout.c b/src/checkout.c index 261dee112..cf0a8b8e7 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -220,19 +220,34 @@ static int checkout_action_wd_only( { bool remove = false; git_checkout_notify_t notify = GIT_CHECKOUT_NOTIFY_NONE; - const git_index_entry *entry; if (!git_pathspec_match_path( pathspec, wd->path, false, workdir->ignore_case)) return 0; /* check if item is tracked in the index but not in the checkout diff */ - if (data->index != NULL && - (entry = git_index_get_bypath(data->index, wd->path, 0)) != NULL) - { - notify = GIT_CHECKOUT_NOTIFY_DIRTY; - remove = ((data->strategy & GIT_CHECKOUT_FORCE) != 0); + if (data->index != NULL) { + if (wd->mode != GIT_FILEMODE_TREE) { + if (git_index_get_bypath(data->index, wd->path, 0) != NULL) { + notify = GIT_CHECKOUT_NOTIFY_DIRTY; + remove = ((data->strategy & GIT_CHECKOUT_FORCE) != 0); + } + } else { + /* for tree entries, we have to see if there are any index + * entries that are contained inside that tree + */ + size_t pos = git_index__prefix_position(data->index, wd->path); + const git_index_entry *e = git_index_get_byindex(data->index, pos); + + if (e != NULL && data->diff->pfxcomp(e->path, wd->path) == 0) { + notify = GIT_CHECKOUT_NOTIFY_DIRTY; + remove = ((data->strategy & GIT_CHECKOUT_FORCE) != 0); + } + } } + + if (notify != GIT_CHECKOUT_NOTIFY_NONE) + /* found in index */; else if (git_iterator_current_is_ignored(workdir)) { notify = GIT_CHECKOUT_NOTIFY_IGNORED; remove = ((data->strategy & GIT_CHECKOUT_REMOVE_IGNORED) != 0); @@ -418,8 +433,6 @@ static int checkout_action_with_wd_dir( return checkout_action_common(data, action, delta, wd); } -#define EXPAND_DIRS_FOR_STRATEGY (GIT_CHECKOUT_FORCE | GIT_CHECKOUT_REMOVE_UNTRACKED | GIT_CHECKOUT_REMOVE_IGNORED) - static int checkout_action( checkout_data *data, git_diff_delta *delta, @@ -431,7 +444,6 @@ static int checkout_action( int cmp = -1, act; int (*strcomp)(const char *, const char *) = data->diff->strcomp; int (*pfxcomp)(const char *str, const char *pfx) = data->diff->pfxcomp; - bool expand_dirs = (data->strategy & EXPAND_DIRS_FOR_STRATEGY) != 0; /* move workdir iterator to follow along with deltas */ @@ -452,18 +464,21 @@ static int checkout_action( if (cmp < 0) { cmp = pfxcomp(delta->old_file.path, wd->path); - if (wd->mode == GIT_FILEMODE_TREE && (cmp == 0 || expand_dirs)) { - /* case 2 or untracked wd item that might need removal */ - if (git_iterator_advance_into_directory(workdir, &wd) < 0) - goto fail; - continue; - } - if (cmp == 0) { - /* case 3 - wd contains non-dir where dir expected */ - act = checkout_action_with_wd_blocker(data, delta, wd); - *wditem_ptr = git_iterator_advance(workdir, &wd) ?

Since we explicitly check if master is existing in `update_head_to_remote` and error out if it doesn't, a repository without master branch could not be cloned. In fact this was later clobbered by what is fixed in #1194. However, this patch introduces a `found` member in `head_info` and sets it accordingly. That also saves us from checking the string length of `branchname` a few times. --- src/clone.c | 26 ++++++++++++++++---------- 1 file changed, 16 insertions(+), 10 deletions(-) diff --git a/src/clone.c b/src/clone.c index ff586a68a..0cf7b4dcc 100644 --- a/src/clone.c +++ b/src/clone.c @@ -105,6 +105,7 @@ struct head_info { git_oid remote_head_oid;

This adds a test that exercises that case inside diff and fixes the code path where we would try to do that. The fix turns out not to be a lot of code since our default file content is already initialized to "" which works in this case.

At this point, the flags are not supported on tree iterators (i.e. there is no functional change over the old API), but the API changes are all made to accomodate this. By the way, I went with a flags parameter because in the future I have a couple of other ideas for iterator flags that will make it easier to fix some diff/status/checkout bugs. --- src/checkout.c | 16 +++--- src/diff.c | 24 ++++----- src/diff_output.c | 10 ++-- src/iterator.c | 118 ++++++++++++++++++++++++++++++--------------- src/iterator.h | 66 +++++++++++++++++++------ tests-clar/diff/iterator.c | 12 +++-- 6 files changed, 165 insertions(+), 81 deletions(-) diff --git a/src/checkout.c b/src/checkout.c index d5a471d0c..411bf3be7 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -224,7 +224,7 @@ static int checkout_action_wd_only( if (!git_pathspec_match_path( pathspec, wd->path, (data->strategy & GIT_CHECKOUT_DISABLE_PATHSPEC_MATCH) != 0, - workdir->ignore_case)) + git_iterator_ignore_case(workdir))) return 0;

This will make it a little easier to emulate `git diff --stat` and the like. Right now, this relies on generating the `git_diff_patch` object, which is a pretty heavyweight way to get stat information. At some future point, it would probably be nice to be able to get this information without allocating the entire `git_diff_patch`, but that's a much larger project. --- include/git2/diff.h | 22 +++++++++++++++++ src/buffer.h | 7 ++++++ src/diff_output.c | 34 +++++++++++++++++++++++++- tests-clar/diff/patch.c | 65 +++++++++++++++++++++++++++++++++++++++++++++++++ 4 files changed, 127 insertions(+), 1 deletion(-) diff --git a/include/git2/diff.h b/include/git2/diff.h index c052f34f8..81c41df04 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -703,6 +703,28 @@ GIT_EXTERN(const git_diff_delta *) git_diff_patch_delta( GIT_EXTERN(size_t) git_diff_patch_num_hunks( git_diff_patch *patch); +/** + * Get line counts of each type in a patch. + * + * This helps imitate a diff --numstat type of output.

Also, I reformatted all of the comments down to 80 cols (and in some cases, slightly updated the wording). --- examples/general.c | 353 +++++++++++++++++++++++++++++++---------------------- 1 file changed, 207 insertions(+), 146 deletions(-) diff --git a/examples/general.c b/examples/general.c index a042be011..c7853fa62 100644 --- a/examples/general.c +++ b/examples/general.c @@ -1,19 +1,20 @@ -// [**libgit2**][lg] is a portable, pure C implementation of the Git core methods -// provided as a re-entrant linkable library with a solid API, allowing you -// to write native speed custom Git applications in any language which -// supports C bindings. +// [**libgit2**][lg] is a portable, pure C implementation of the Git core +// methods provided as a re-entrant linkable library with a solid API, +// allowing you to write native speed custom Git applications in any +// language which supports C bindings. // // This file is an example of using that API in a real, compilable C file. -// As the API is updated, this file will be updated to demonstrate the -// new functionality. +// As the API is updated, this file will be updated to demonstrate the new +// functionality. // -// If you're trying to write something in C using [libgit2][lg], you will also want -// to check out the generated [API documentation][ap].

All the ones fixed in this commit are actually false positives, but I've reorganized the code to hopefully make it easier for static analysis tools to correctly understand the structure. I wouldn't do this if I felt like it was making the code harder to read or worse for humans, but in this case, these fixes don't seem too bad and will hopefully make it easier for better analysis tools to get at any real issues. --- src/checkout.c | 10 +++++++--- src/diff_output.c | 11 ++++++----- src/notes.c | 2 +- src/refs.c | 2 +- src/transports/winhttp.c | 2 +- tests-clar/clar_libgit2.c | 16 ++++++++++------ tests-clar/core/env.c | 2 ++ 7 files changed, 28 insertions(+), 17 deletions(-) diff --git a/src/checkout.c b/src/checkout.c index 0ce283beb..59cd218a9 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -64,6 +64,7 @@ static int checkout_notify( { git_diff_file wdfile; const git_diff_file *baseline = NULL, *target = NULL, *workdir = NULL; + const char *path = NULL; if (!data->opts.notify_cb) return 0; @@ -81,6 +82,8 @@ static int checkout_notify( wdfile.mode = wditem->mode; workdir = &wdfile; + + path = wditem->path; } if (delta) { @@ -101,11 +104,12 @@ static int checkout_notify( baseline = &delta->old_file; break; } + + path = delta->old_file.path; } return data->opts.notify_cb( - why, delta ? delta->old_file.path : wditem->path, - baseline, target, workdir, data->opts.notify_payload); + why, path, baseline, target, workdir, data->opts.notify_payload); } static bool checkout_is_workdir_modified( @@ -683,7 +687,7 @@ static int blob_content_to_file( { int error = -1, nb_filters = 0; mode_t file_mode = opts->file_mode; - bool dont_free_filtered = false; + bool dont_free_filtered; git_buf unfiltered = GIT_BUF_INIT, filtered = GIT_BUF_INIT; git_vector filters = GIT_VECTOR_INIT; diff --git a/src/diff_output.c b/src/diff_output.c index 26b073aad..88ccc9d45 100644 --- a/src/diff_output.c +++ b/src/diff_output.c @@ -1280,14 +1280,15 @@ static void set_data_from_buffer( { file->size = (git_off_t)buffer_len; file->mode = 0644; + map->len = buffer_len; - if (!buffer) + if (!buffer) { file->flags |= GIT_DIFF_FILE_NO_DATA; - else + map->data = NULL; + } else { + map->data = (char *)buffer; git_odb_hash(&file->oid, buffer, buffer_len, GIT_OBJ_BLOB); - - map->len = buffer_len; - map->data = (char *)buffer; + } } typedef struct { diff --git a/src/notes.c b/src/notes.c index eff80bc82..f5537db3f 100644 --- a/src/notes.c +++ b/src/notes.c @@ -147,7 +147,7 @@ static int manipulate_note_in_tree_r( int fanout, int current_error)) { - int error = -1; + int error; git_tree *subtree = NULL, *new = NULL; char subtree_name[3]; diff --git a/src/refs.c b/src/refs.c index 7dabfefae..866c230e6 100644 --- a/src/refs.c +++ b/src/refs.c @@ -1493,7 +1493,7 @@ int git_reference_foreach( /* list all the packed references first */ if (list_flags & GIT_REF_PACKED) { const char *ref_name; - void *ref; + void *ref = NULL; GIT_UNUSED(ref); if (packed_load(repo) < 0) diff --git a/src/transports/winhttp.c b/src/transports/winhttp.c index 64bfece34..970fa53bd 100644 --- a/src/transports/winhttp.c +++ b/src/transports/winhttp.c @@ -88,7 +88,7 @@ static int apply_basic_credential(HINTERNET request, git_cred *cred) git_cred_userpass_plaintext *c = (git_cred_userpass_plaintext *)cred; git_buf buf = GIT_BUF_INIT, raw = GIT_BUF_INIT; wchar_t *wide = NULL; - int error = -1, wide_len; + int error = -1, wide_len = 0; git_buf_printf(&raw, "%s:%s", c->username, c->password); diff --git a/tests-clar/clar_libgit2.c b/tests-clar/clar_libgit2.c index 63efd5954..698aa90f0 100644 --- a/tests-clar/clar_libgit2.c +++ b/tests-clar/clar_libgit2.c @@ -86,14 +86,18 @@ int cl_setenv(const char *name, const char *value) git__utf8_to_16(name_utf16, GIT_WIN_PATH, name); - if (value != NULL) + if (value) { git__utf8_to_16(value_utf16, GIT_WIN_PATH, value); + cl_assert(SetEnvironmentVariableW(name_utf16, value_utf16)); + } else { + /* Windows XP returns 0 (failed) when passing NULL for lpValue when + * lpName does not exist in the environment block.

This also separates the text and binary hash calculators into two separate functions instead of have more if statements inside the loop.

In so doing, I realized that the use of git_buf in the hashsig API was not needed and actually just made it harder to use, so I tweaked that API as well. Note that the similarity metric is still not hooked up in the find_similarity code - this is just setting out the function that will be used. --- include/git2/diff.h | 30 +++++++++++++++++++++-- src/diff_tform.c | 64 ++++++++++++++++++++++++++++++++++++++++++++++++ src/hashsig.c | 5 ++-- src/hashsig.h | 6 +++-- tests-clar/core/buffer.c | 22 ++++++++--------- 5 files changed, 110 insertions(+), 17 deletions(-) diff --git a/include/git2/diff.h b/include/git2/diff.h index d90fedfbd..c0f48368e 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -387,20 +387,46 @@ typedef enum { /** split large rewrites into delete/add pairs (`--break-rewrites=/M`) */ GIT_DIFF_FIND_AND_BREAK_REWRITES = (1 << 4), + + /** measure similarity ignoring leading whitespace (default) */ + GIT_DIFF_FIND_IGNORE_LEADING_WHITESPACE = 0, + /** measure similarity ignoring all whitespace */ + GIT_DIFF_FIND_IGNORE_WHITESPACE = (1 << 6), + /** measure similarity including all data */ + GIT_DIFF_FIND_DONT_IGNORE_WHITESPACE = (1 << 7), } git_diff_find_t; /** * Pluggable similarity metric */ typedef struct { - int (*calc_signature)(void **out, const git_diff_file *file, void *payload); + int (*file_signature)( + void **out, const git_diff_file *file, + const char *fullpath, void *payload); + int (*buffer_signature)( + void **out, const git_diff_file *file, + const char *buf, size_t buflen, void *payload); void (*free_signature)(void *sig, void *payload); - int (*calc_similarity)(int *score, void *siga, void *sigb, void *payload); + int (*similarity)(int *score, void *siga, void *sigb, void *payload); void *payload; } git_diff_similarity_metric; /** * Control behavior of rename and copy detection + * + * These options mostly mimic parameters that can be passed to git-diff. + * + * - `rename_threshold` is the same as the -M option with a value + * - `copy_threshold` is the same as the -C option with a value + * - `rename_from_rewrite_threshold` matches the top of the -B option + * - `break_rewrite_threshold` matches the bottom of the -B option + * - `target_limit` matches the -l option + * + * The `metric` option allows you to plug in a custom similarity metric. + * Set it to NULL for the default internal metric which is based on sampling + * hashes of ranges of data in the file.

This replaces that (with no net change in structure size) with a full set of flags. The flag values that were already in use for individual git_diff_file objects are reused for the delta flags, too (along with renaming those flags to make it clear that they are used more generally). This (a) makes things somewhat more consistent (because I was using a -1 value in the "boolean" binary field to indicate unset, whereas now I can just use the flags that are easier to understand), and (b) will make it easier for me to add some additional flags to the delta object in the future, such as marking the results of a copy/rename detection or other deltas that might want a special indicator. While making this change, I officially moved some of the flags that were internal only into the private diff header. This also allowed me to remove a gross hack in rename/copy detect code where I was overwriting the status field with an internal value. --- include/git2/diff.h | 54 +++++++-------- src/checkout.c | 2 +- src/diff.c | 8 +-- src/diff.h | 10 ++- src/diff_output.c | 147 ++++++++++++++++++++--------------------- src/diff_tform.c | 16 ++--- tests-clar/diff/diff_helpers.c | 5 +- tests-clar/diff/diffiter.c | 8 +-- 8 files changed, 128 insertions(+), 122 deletions(-) diff --git a/include/git2/diff.h b/include/git2/diff.h index c0f48368e..7f165041a 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -88,10 +88,9 @@ typedef enum { GIT_DIFF_INCLUDE_UNTRACKED = (1 << 8), /** Include unmodified files in the diff list */ GIT_DIFF_INCLUDE_UNMODIFIED = (1 << 9), - /** Even with the GIT_DIFF_INCLUDE_UNTRACKED flag, when an untracked - * directory is found, only a single entry for the directory is added - * to the diff list; with this flag, all files under the directory will - * be included, too. + /** Even with GIT_DIFF_INCLUDE_UNTRACKED, an entire untracked directory + * will be marked with only a single entry in the diff list; this flag + * adds all files under the directory as UNTRACKED entries, too. */ GIT_DIFF_RECURSE_UNTRACKED_DIRS = (1 << 10), /** If the pathspec is set in the diff options, this flags means to @@ -120,6 +119,11 @@ typedef enum { GIT_DIFF_INCLUDE_TYPECHANGE_TREES = (1 << 16), /** Ignore file mode changes */ GIT_DIFF_IGNORE_FILEMODE = (1 << 17), + /** Even with GIT_DIFF_INCLUDE_IGNORED, an entire ignored directory + * will be marked with only a single entry in the diff list; this flag + * adds all files under the directory as IGNORED entries, too. + */ + GIT_DIFF_RECURSE_IGNORED_DIRS = (1 << 10), } git_diff_option_t; /** @@ -133,20 +137,18 @@ typedef enum { typedef struct git_diff_list git_diff_list; /** - * Flags for the file object on each side of a diff. + * Flags for the delta object and the file objects on each side. * - * Note: most of these flags are just for **internal** consumption by - * libgit2, but some of them may be interesting to external users. + * These flags are used for both the `flags` value of the `git_diff_delta` + * and the flags for the `git_diff_file` objects representing the old and + * new sides of the delta.

The existing tests all pass, but the new functionality isn't currently well tested. The integration does go through the pluggable metric interface, so it should be possible to drop in an alternative to the internal metric that libgit2 implements. This comes along with a behavior change for an existing interface; namely, passing two NULLs to git_diff_blobs (or passing NULLs to git_diff_blob_to_buffer) will now call the file_cb parameter zero times instead of one time. I know it's strange that that change is paired with this other change, but it emerged from some initialization changes that I ended up making. --- include/git2/diff.h | 16 ++-- src/diff_output.c | 56 +++++++++--- src/diff_tform.c | 235 +++++++++++++++++++++++++++++++++++++------------ tests-clar/diff/blob.c | 4 +- 4 files changed, 235 insertions(+), 76 deletions(-) diff --git a/include/git2/diff.h b/include/git2/diff.h index 7f165041a..379f4694e 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -379,7 +379,7 @@ typedef struct git_diff_patch git_diff_patch; typedef enum { /** look for renames?

There is still more testing to do - these tests are just partially covering the cases. There is also one bug fix in this where a change set with only MODIFY being broken into ADD/DELETE (due to low self-similarity) without any additional RENAMED entries would end up not processing the split requests (because the num_rewrites counter got reset). --- include/git2/diff.h | 3 + src/diff_tform.c | 2 - tests-clar/diff/rename.c | 117 ++++++++++++++++++++- tests-clar/resources/renames/.gitted/index | Bin 272 -> 352 bytes tests-clar/resources/renames/.gitted/logs/HEAD | 2 + .../renames/.gitted/logs/refs/heads/master | 2 + .../19/dd32dfb1520a64e5bbaae8dce6ef423dfa2f13 | 1 + .../1c/068dee5790ef1580cfc4cd670915b48d790084 | Bin 0 -> 176 bytes .../36/020db6cdacaa93497f31edcd8f242ff9bc366d | Bin 0 -> 431 bytes .../3c/04741dd4b96c4ae4b00ec0f6e10c816a30aad2 | Bin 0 -> 159 bytes .../42/10ffd5c390b21dd5483375e75288dea9ede512 | Bin 0 -> 1145 bytes .../4e/4cae3e7dd56ed74bff39526d0469e554432953 | Bin 0 -> 452 bytes .../5e/26abc56a5a84d89790f45416648899cbe13109 | Bin 0 -> 163 bytes .../9a/69d960ae94b060f56c2a8702545e2bb1abb935 | Bin 0 -> 464 bytes .../d7/9b202de198fa61b02424b9e25e840dc75e1323 | Bin 0 -> 421 bytes .../ea/f4a3e3bfe68585e90cada20736ace491cd100b | 5 + .../f9/0d4fc20ecddf21eebe6a37e9225d244339d2b5 | Bin 0 -> 441 bytes .../resources/renames/.gitted/refs/heads/master | 2 +- tests-clar/resources/renames/ikeepsix.txt | 27 +++++ tests-clar/resources/renames/sevencities.txt | 49 --------- tests-clar/resources/renames/sixserving.txt | 43 ++++---- tests-clar/resources/renames/songof7cities.txt | 49 +++++++++ tests-clar/resources/renames/songofseven.txt | 49 --------- tests-clar/resources/renames/untimely.txt | 24 +++++ 24 files changed, 251 insertions(+), 124 deletions(-) create mode 100644 tests-clar/resources/renames/.gitted/objects/19/dd32dfb1520a64e5bbaae8dce6ef423dfa2f13 create mode 100644 tests-clar/resources/renames/.gitted/objects/1c/068dee5790ef1580cfc4cd670915b48d790084 create mode 100644 tests-clar/resources/renames/.gitted/objects/36/020db6cdacaa93497f31edcd8f242ff9bc366d create mode 100644 tests-clar/resources/renames/.gitted/objects/3c/04741dd4b96c4ae4b00ec0f6e10c816a30aad2 create mode 100644 tests-clar/resources/renames/.gitted/objects/42/10ffd5c390b21dd5483375e75288dea9ede512 create mode 100644 tests-clar/resources/renames/.gitted/objects/4e/4cae3e7dd56ed74bff39526d0469e554432953 create mode 100644 tests-clar/resources/renames/.gitted/objects/5e/26abc56a5a84d89790f45416648899cbe13109 create mode 100644 tests-clar/resources/renames/.gitted/objects/9a/69d960ae94b060f56c2a8702545e2bb1abb935 create mode 100644 tests-clar/resources/renames/.gitted/objects/d7/9b202de198fa61b02424b9e25e840dc75e1323 create mode 100644 tests-clar/resources/renames/.gitted/objects/ea/f4a3e3bfe68585e90cada20736ace491cd100b create mode 100644 tests-clar/resources/renames/.gitted/objects/f9/0d4fc20ecddf21eebe6a37e9225d244339d2b5 create mode 100644 tests-clar/resources/renames/ikeepsix.txt delete mode 100644 tests-clar/resources/renames/sevencities.txt create mode 100644 tests-clar/resources/renames/songof7cities.txt delete mode 100644 tests-clar/resources/renames/songofseven.txt create mode 100644 tests-clar/resources/renames/untimely.txt diff --git a/include/git2/diff.h b/include/git2/diff.h index 379f4694e..ca3484332 100644 --- a/include/git2/diff.h +++ b/include/git2/diff.h @@ -390,6 +390,9 @@ typedef enum { /** split large rewrites into delete/add pairs (`--break-rewrites=/M`) */ GIT_DIFF_FIND_AND_BREAK_REWRITES = (1 << 4), + /** turn on all finding features */ + GIT_DIFF_FIND_ALL = (0x1f), + /** measure similarity ignoring leading whitespace (default) */ GIT_DIFF_FIND_IGNORE_LEADING_WHITESPACE = 0, /** measure similarity ignoring all whitespace */ diff --git a/src/diff_tform.c b/src/diff_tform.c index 48332d3e5..ae0fd36d6 100644 --- a/src/diff_tform.c +++ b/src/diff_tform.c @@ -561,8 +561,6 @@ int git_diff_find_similar( /* next rewrite the diffs with renames / copies */ - num_rewrites = 0;

So, this started with me recreating a couple of hooks, including a sample and symlink, and adding tests that they got created correctly in the various circumstances, including with the SHARED modes, etc. Unfortunately this uncovered some issues with how directories and symlinks were copied and chmod'ed. Also, there was a FIXME in the code related to the chmod behavior as well. Going back over the directory creation logic for setting up a repository, I found it was a little difficult to read and could result in creating and/or chmod'ing directories that the user almost certainly didn't intend. So that let to this work which makes repo initialization much more careful (and hopefully easier to follow). It required a couple of extensions / changes to core fileops utilities, but I also think those are for the better, at least for git_futils_cp_r in terms of being careful about what actions it takes. --- src/fileops.c | 123 +++++++++++++++------- src/fileops.h | 14 +-- src/repository.c | 96 ++++++++++++----- tests-clar/repo/init.c | 117 ++++++++++++++++++-- tests-clar/resources/template/hooks/link.sample | 1 + tests-clar/resources/template/hooks/update.sample | 9 ++ 6 files changed, 278 insertions(+), 82 deletions(-) create mode 120000 tests-clar/resources/template/hooks/link.sample create mode 100755 tests-clar/resources/template/hooks/update.sample diff --git a/src/fileops.c b/src/fileops.c index 3531e75b8..2b2db4b37 100644 --- a/src/fileops.c +++ b/src/fileops.c @@ -272,6 +272,10 @@ int git_futils_mkdir( } /* if we are not supposed to made the last element, truncate it */ + if ((flags & GIT_MKDIR_SKIP_LAST2) != 0) { + git_buf_rtruncate_at_char(&make_path, '/'); + flags |= GIT_MKDIR_SKIP_LAST; + } if ((flags & GIT_MKDIR_SKIP_LAST) != 0) git_buf_rtruncate_at_char(&make_path, '/'); @@ -303,34 +307,34 @@ int git_futils_mkdir( int already_exists = 0; switch (errno) { - case EEXIST: - if (!lastch && (flags & GIT_MKDIR_VERIFY_DIR) != 0 && - !git_path_isdir(make_path.ptr)) { - giterr_set( - GITERR_OS, "Existing path is not a directory '%s'", - make_path.ptr); - error = GIT_ENOTFOUND; - goto fail; - } - - already_exists = 1; - break; - case ENOSYS: - /* Solaris can generate this error if you try to mkdir - * a path which is already a mount point.

This rearranges the order of parameters, simplifies the naming of a number of functions, and makes somewhat better use of macros internally to clean up the iterator code. This also expands the test coverage of iterator functionality, making sure that case sensitive range-limited iteration works correctly. --- src/checkout.c | 39 ++-- src/diff.c | 41 ++-- src/index.c | 51 ---- src/index.h | 3 - src/iterator.c | 257 +++++++++++---------- src/iterator.h | 97 ++++---- src/notes.c | 6 +- src/submodule.c | 12 +- tests-clar/diff/iterator.c | 74 +++--- tests-clar/repo/iterator.c | 210 +++++++++++++++++ tests-clar/resources/icase/.gitted/HEAD | 1 + tests-clar/resources/icase/.gitted/config | 7 + tests-clar/resources/icase/.gitted/description | 1 + tests-clar/resources/icase/.gitted/index | Bin 0 -> 1392 bytes tests-clar/resources/icase/.gitted/info/exclude | 6 + tests-clar/resources/icase/.gitted/logs/HEAD | 1 + .../resources/icase/.gitted/logs/refs/heads/master | 1 + .../3e/257c57f136a1cb8f2b8e9a2e5bc8ec0258bdce | Bin 0 -> 114 bytes .../4d/d6027d083575c7431396dc2a3174afeb393c93 | Bin 0 -> 61 bytes .../62/e0af52c199ec731fe4ad230041cd3286192d49 | Bin 0 -> 19 bytes .../76/d6e1d231b1085fcce151427e9899335de74be6 | 3 + .../d4/4e18fb93b7107b5cd1b95d601591d77869a1b6 | Bin 0 -> 21 bytes .../resources/icase/.gitted/refs/heads/master | 1 + tests-clar/resources/icase/B | 1 + tests-clar/resources/icase/D | 1 + tests-clar/resources/icase/F | 1 + tests-clar/resources/icase/H | 1 + tests-clar/resources/icase/J | 1 + tests-clar/resources/icase/L/1 | 1 + tests-clar/resources/icase/L/B | 1 + tests-clar/resources/icase/L/D | 1 + tests-clar/resources/icase/L/a | 1 + tests-clar/resources/icase/L/c | 1 + tests-clar/resources/icase/a | 1 + tests-clar/resources/icase/c | 1 + tests-clar/resources/icase/e | 1 + tests-clar/resources/icase/g | 1 + tests-clar/resources/icase/i | 1 + tests-clar/resources/icase/k/1 | 1 + tests-clar/resources/icase/k/B | 1 + tests-clar/resources/icase/k/D | 1 + tests-clar/resources/icase/k/a | 1 + tests-clar/resources/icase/k/c | 1 + tests-clar/status/worktree.c | 3 + 44 files changed, 524 insertions(+), 310 deletions(-) create mode 100644 tests-clar/repo/iterator.c create mode 100644 tests-clar/resources/icase/.gitted/HEAD create mode 100644 tests-clar/resources/icase/.gitted/config create mode 100644 tests-clar/resources/icase/.gitted/description create mode 100644 tests-clar/resources/icase/.gitted/index create mode 100644 tests-clar/resources/icase/.gitted/info/exclude create mode 100644 tests-clar/resources/icase/.gitted/logs/HEAD create mode 100644 tests-clar/resources/icase/.gitted/logs/refs/heads/master create mode 100644 tests-clar/resources/icase/.gitted/objects/3e/257c57f136a1cb8f2b8e9a2e5bc8ec0258bdce create mode 100644 tests-clar/resources/icase/.gitted/objects/4d/d6027d083575c7431396dc2a3174afeb393c93 create mode 100644 tests-clar/resources/icase/.gitted/objects/62/e0af52c199ec731fe4ad230041cd3286192d49 create mode 100644 tests-clar/resources/icase/.gitted/objects/76/d6e1d231b1085fcce151427e9899335de74be6 create mode 100644 tests-clar/resources/icase/.gitted/objects/d4/4e18fb93b7107b5cd1b95d601591d77869a1b6 create mode 100644 tests-clar/resources/icase/.gitted/refs/heads/master create mode 100644 tests-clar/resources/icase/B create mode 100644 tests-clar/resources/icase/D create mode 100644 tests-clar/resources/icase/F create mode 100644 tests-clar/resources/icase/H create mode 100644 tests-clar/resources/icase/J create mode 100644 tests-clar/resources/icase/L/1 create mode 100644 tests-clar/resources/icase/L/B create mode 100644 tests-clar/resources/icase/L/D create mode 100644 tests-clar/resources/icase/L/a create mode 100644 tests-clar/resources/icase/L/c create mode 100644 tests-clar/resources/icase/a create mode 100644 tests-clar/resources/icase/c create mode 100644 tests-clar/resources/icase/e create mode 100644 tests-clar/resources/icase/g create mode 100644 tests-clar/resources/icase/i create mode 100644 tests-clar/resources/icase/k/1 create mode 100644 tests-clar/resources/icase/k/B create mode 100644 tests-clar/resources/icase/k/D create mode 100644 tests-clar/resources/icase/k/a create mode 100644 tests-clar/resources/icase/k/c diff --git a/src/checkout.c b/src/checkout.c index 19ac913d3..0be87b4a3 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -456,7 +456,7 @@ static int checkout_action( while (1) { if (!wd) return checkout_action_no_wd(data, delta); - + cmp = strcomp(wd->path, delta->old_file.path); /* 1. wd before delta ("a/a" before "a/b") @@ -473,9 +473,9 @@ static int checkout_action( if (cmp == 0) { if (wd->mode == GIT_FILEMODE_TREE) { /* case 2 - entry prefixed by workdir tree */ - if (git_iterator_advance_into_directory(workdir, &wd) < 0) + if (git_iterator_advance_into(&wd, workdir) < 0) goto fail; - + *wditem_ptr = wd; continue; } @@ -484,14 +484,14 @@ static int checkout_action( if (delta->old_file.path[strlen(wd->path)] == '/') { act = checkout_action_with_wd_blocker(data, delta, wd); *wditem_ptr = - git_iterator_advance(workdir, &wd) ?

Previously the working directory iterator behaved differently from the other two. Each iterator can now operate in one of three modes: 1. *No tree results, auto expand trees* means that only non- tree items will be returned and when a tree/directory is encountered, we will automatically descend into it. 2. *Tree results, auto expand trees* means that results will be given for every item found, including trees, but you only need to call normal git_iterator_advance to yield every item (i.e. trees returned with pre-order iteration). 3. *Tree results, no auto expand* means that calling the normal git_iterator_advance when looking at a tree will not descend into the tree, but will skip over it to the next entry in the parent. Previously, behavior 1 was the only option for index and tree iterators, and behavior 3 was the only option for workdir. The main public API implications of this are that the `git_iterator_advance_into()` call is now valid for all iterators, not just working directory iterators, and all the existing uses of working directory iterators explicitly use the GIT_ITERATOR_DONT_AUTOEXPAND (for now). Interestingly, the majority of the implementation was in the index iterator, since there are no tree entries there and now have to fake them. The tree and working directory iterators only required small modifications. --- src/checkout.c | 3 +- src/diff.c | 24 +++- src/iterator.c | 315 ++++++++++++++++++++++++++++++++++++--------- src/iterator.h | 57 ++++---- tests-clar/diff/iterator.c | 12 +- tests-clar/repo/iterator.c | 197 ++++++++++++++++++++++++++-- 6 files changed, 498 insertions(+), 110 deletions(-) diff --git a/src/checkout.c b/src/checkout.c index 41de0d7d4..68ebbe31d 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -1243,7 +1243,8 @@ int git_checkout_iterator( if ((error = git_iterator_reset(target, data.pfx, data.pfx)) < 0 || (error = git_iterator_for_workdir( - &workdir, data.repo, iterflags, data.pfx, data.pfx)) < 0 || + &workdir, data.repo, iterflags | GIT_ITERATOR_DONT_AUTOEXPAND, + data.pfx, data.pfx)) < 0 || (error = git_iterator_for_tree( &baseline, data.opts.baseline, iterflags, data.pfx, data.pfx)) < 0) goto cleanup;

If case insensitivity resulted in member elements being equivalent to one another, and those member elements were trees, then the children of the colliding elements would be processed in sequence instead of in a single flattened list. This meant that the tree iterator was not truly acting like a case-insensitive list. This completely reworks the tree iterator to manage lists with case insensitive equivalence classes and advance through the items in a unified manner in a single sorted frame. It is possible that at a future date we might want to update this to separate the case insensitive and case sensitive tree iterators so that the case sensitive one could be a minimal amount of code and the insensitive one would always know what it needed to do without checking flags. But there would be so much shared code between the two, that I'm not sure it that's a win. For now, this gets what we need. More tests are needed, though. --- src/hashsig.c | 21 +- src/iterator.c | 487 ++++++++++++++++++++++++--------------------- src/posix.h | 3 +- src/unix/posix.h | 1 + src/util.c | 30 +++ src/util.h | 4 + tests-clar/repo/iterator.c | 210 ++++++++++++++----- 7 files changed, 467 insertions(+), 289 deletions(-) diff --git a/src/hashsig.c b/src/hashsig.c index e9c5164a4..3a75aaaed 100644 --- a/src/hashsig.c +++ b/src/hashsig.c @@ -6,6 +6,7 @@ */ #include "hashsig.h" #include "fileops.h" +#include "util.h" typedef uint32_t hashsig_t; typedef uint64_t hashsig_state; @@ -19,7 +20,7 @@ typedef uint64_t hashsig_state; #define HASHSIG_HEAP_SIZE ((1 << 7) - 1) -typedef int (GIT_STDLIB_CALL *hashsig_cmp)(const void *a, const void *b); +typedef int (*hashsig_cmp)(const void *a, const void *b, void *); typedef struct { int size, asize; @@ -53,15 +54,17 @@ static void hashsig_heap_init(hashsig_heap *h, hashsig_cmp cmp) h->cmp = cmp; } -static int GIT_STDLIB_CALL hashsig_cmp_max(const void *a, const void *b) +static int hashsig_cmp_max(const void *a, const void *b, void *payload) { hashsig_t av = *(const hashsig_t *)a, bv = *(const hashsig_t *)b; + GIT_UNUSED(payload); return (av < bv) ?

This points out a behavior quirk in the current version that I'd like to fix - namely, all tree entries get mapped to one version of the case pattern in the ci code - i.e. even if you have A/1.txt and a/2.txt, both will be reported as a/1.txt and a/2.txt because we only copy the name of a file at a given frame once. It would be nice to fix this, but I'm worried about how complex that is if you get a/B/c/1.txt and A/b/C/2.txt. It may require a walk up the frames whenever you advance to the next item in a blended equivalence class. --- tests-clar/repo/iterator.c | 93 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 93 insertions(+) diff --git a/tests-clar/repo/iterator.c b/tests-clar/repo/iterator.c index 3d72d7a49..63613e903 100644 --- a/tests-clar/repo/iterator.c +++ b/tests-clar/repo/iterator.c @@ -1,6 +1,7 @@ #include "clar_libgit2.h" #include "iterator.h" #include "repository.h" +#include static git_repository *g_repo; @@ -24,11 +25,19 @@ static void expect_iterator_items( const git_index_entry *entry; int count; int no_trees = !(git_iterator_flags(i) & GIT_ITERATOR_INCLUDE_TREES); + bool v = false; + + if (expected_flat < 0) { v = true; expected_flat = -expected_flat; } + if (expected_total < 0) { v = true; expected_total = -expected_total; } count = 0; cl_git_pass(git_iterator_current(&entry, i)); + if (v) fprintf(stderr, "== %s ==\n", no_trees ?

The tree_iterator_entry objects are now kept as pointers that are allocated from a git_pool, so that we may use git__tsort_r for sorting (which is better than qsort, given that the tree is likely mostly ordered already). Those tree_iterator_entry objects now keep direct pointers to the data they refer to instead of keeping indirect index values. This simplifies a lot of the data structure traversal code. This also adds bsearch to find the start item position for range- limited tree iterators, and is more explicit about using git_path_cmp instead of reimplementing it. The git_path_cmp changed a bit to make it easier for tree_iterators to use it (but it was barely being used previously, so not a big deal). This adds a git_pool_free_array function that efficiently frees a list of pool allocated pointers (which the tree_iterator keeps). Also, added new tests for the git_pool free list functionality that was not previously being tested (or used). --- src/iterator.c | 352 ++++++++++++++++++++++--------------------------- src/path.c | 29 +--- src/path.h | 8 +- src/pool.c | 24 +++- src/pool.h | 7 + src/tree.c | 21 +-- tests-clar/core/pool.c | 50 +++++++ 7 files changed, 251 insertions(+), 240 deletions(-) diff --git a/src/iterator.c b/src/iterator.c index 1ac6a4919..b15bcedd8 100644 --- a/src/iterator.c +++ b/src/iterator.c @@ -148,8 +148,7 @@ int git_iterator_for_nothing( const char *start, const char *end) { - empty_iterator *i = git__calloc(1, sizeof(empty_iterator));

Behind the scenes, I changed the logic for finding files to have a notion of a git_strarray that represents a search path and to store a separate search path for each of the three tiers of config file. For each tier, I implemented a function to initialize it to default values (generally based on environment variables), and then general interfaces to get it, set it, reset it, and prepend new directories to it. Next, I exposed these interfaces through the git_libgit2_opts interface, reusing the GIT_CONFIG_LEVEL_SYSTEM, etc., constants for the user to control which search path they were modifying. There are alternative designs for the opts interface / argument ordering, so I'm putting this phase out for discussion. Additionally, I ended up doing a little bit of clean up regarding attr.h and attr_file.h, adding a new attrcache.h so the other two files wouldn't have to be included in so many places. --- include/git2/common.h | 46 +++++++++-- include/git2/strarray.h | 30 ++++++- src/attr.c | 43 ++++++---- src/attr.h | 20 +---- src/attr_file.c | 1 + src/attr_file.h | 1 + src/attrcache.h | 24 ++++++ src/common.h | 6 ++ src/config.c | 88 +++++++------------- src/config.h | 7 +- src/fileops.c | 161 +++++++++++++++++++++++++------------ src/fileops.h | 46 +++++++++-- src/ignore.c | 3 +- src/ignore.h | 5 ++ src/repository.h | 2 +- src/util.c | 106 ++++++++++++++++++++++-- src/win32/findfile.c | 208 +++++++++++++++++++++++++++++++++++------------- src/win32/findfile.h | 12 +-- tests-clar/core/env.c | 104 ++++++++++++++++++++++-- 19 files changed, 672 insertions(+), 241 deletions(-) create mode 100644 src/attrcache.h diff --git a/include/git2/common.h b/include/git2/common.h index 7066d5ea3..137ffa0a4 100644 --- a/include/git2/common.h +++ b/include/git2/common.h @@ -128,7 +128,10 @@ enum { GIT_OPT_GET_MWINDOW_SIZE, GIT_OPT_SET_MWINDOW_SIZE, GIT_OPT_GET_MWINDOW_MAPPED_LIMIT, - GIT_OPT_SET_MWINDOW_MAPPED_LIMIT + GIT_OPT_SET_MWINDOW_MAPPED_LIMIT, + GIT_OPT_GET_SEARCH_PATH, + GIT_OPT_SET_SEARCH_PATH, + GIT_OPT_PREPEND_SEARCH_PATH, }; /** @@ -136,17 +139,44 @@ enum { * * Available options: * - * opts(GIT_OPT_MWINDOW_SIZE, size_t): - * set the maximum mmap window size + * opts(GIT_OPT_GET_MWINDOW_SIZE, size_t *): + * Get the maximum mmap window size * - * opts(GIT_OPT_MWINDOW_MAPPED_LIMIT, size_t): - * set the maximum amount of memory that can be mapped at any time + * opts(GIT_OPT_SET_MWINDOW_SIZE, size_t): + * Set the maximum mmap window size + * + * opts(GIT_OPT_GET_MWINDOW_MAPPED_LIMIT, size_t *): + * Get the maximum memory that will be mapped in total by the library + * + * opts(GIT_OPT_SET_MWINDOW_MAPPED_LIMIT, size_t): + * Set the maximum amount of memory that can be mapped at any time * by the library * - * @param option Option key - * @param ... value to set the option + * opts(GIT_OPT_GET_SEARCH_PATH, const git_strarray **, int level) + * Get a strarray of the search path for a given level of config + * data.

This makes it simpler to get and set the value. I also added code to expand "$PATH" when setting a new value to embed the old value of the path.

Fix sort order problem with submodules where "mod" was sorting after "mod-plus" because they were being sorted as "mod/" and "mod-plus/". This involved pushing the "contains a .git entry" test significantly lower in the stack. 2. Reinstate behavior that a directory which contains a .git entry will be treated as a submodule during iteration even if it is not yet added to the .gitmodules. 3. Now that any directory containing .git is reported as submodule, we have to be more careful checking for GIT_EEXISTS when we do a submodule lookup, because that is the error code that is returned by git_submodule_lookup when you try to look up a directory containing .git that has no record in gitmodules or the index. --- src/diff.c | 10 ++- src/diff_output.c | 5 ++ src/iterator.c | 4 +-

They attempt to minimize the number of reallocations done and they directly write the buffer data as needed if they know that there is enough memory allocated to memcpy data. Tests are added for these new functions. The crlf.c code is updated to use the new functions. Removed the include of buf_text.h from filter.h and just include it more narrowly in the places that need it. --- src/blob.c | 1 + src/buf_text.c | 77 ++++++++++++++++++++++++++++++++++++++ src/buf_text.h | 14 +++++++ src/checkout.c | 1 + src/crlf.c | 80 +++++++++------------------------------- src/diff_output.c | 1 + src/filter.h | 1 - tests-clar/core/buffer.c | 82 +++++++++++++++++++++++++++++++++++++++++ tests-clar/object/blob/filter.c | 1 + 9 files changed, 194 insertions(+), 64 deletions(-) diff --git a/src/blob.c b/src/blob.c index 3ff141c7f..c0514fc13 100644 --- a/src/blob.c +++ b/src/blob.c @@ -12,6 +12,7 @@ #include "common.h" #include "blob.h" #include "filter.h" +#include "buf_text.h" const void *git_blob_rawcontent(const git_blob *blob) { diff --git a/src/buf_text.c b/src/buf_text.c index 3a8f442b4..443454b5f 100644 --- a/src/buf_text.c +++ b/src/buf_text.c @@ -60,6 +60,83 @@ void git_buf_text_unescape(git_buf *buf) buf->size = git__unescape(buf->ptr); } +int git_buf_text_crlf_to_lf(git_buf *tgt, const git_buf *src) +{ + const char *scan = src->ptr; + const char *scan_end = src->ptr + src->size; + const char *next = memchr(scan, '\r', src->size); + char *out; + + assert(tgt != src); + + if (!next) + return GIT_ENOTFOUND; + + /* reduce reallocs while in the loop */ + if (git_buf_grow(tgt, src->size) < 0) + return -1; + out = tgt->ptr; + tgt->size = 0; + + /* Find the next \r and copy whole chunk up to there to tgt */ + for (; next; scan = next + 1, next = memchr(scan, '\r', scan_end - scan)) { + if (next > scan) { + size_t copylen = next - scan; + memcpy(out, scan, copylen); + out += copylen; + } + + /* Do not drop \r unless it is followed by \n */ + if (next[1] != '\n') + *out++ = '\r'; + } + + /* Copy remaining input into dest */ + memcpy(out, scan, scan_end - scan + 1); /* +1 for NUL byte */ + out += (scan_end - scan); + tgt->size = out - tgt->ptr; + + return 0; +} + +int git_buf_text_lf_to_crlf(git_buf *tgt, const git_buf *src) +{ + const char *start = src->ptr; + const char *end = start + src->size; + const char *scan = start; + const char *next = memchr(scan, '\n', src->size); + + assert(tgt != src); + + if (!next) + return GIT_ENOTFOUND; + + /* attempt to reduce reallocs while in the loop */ + if (git_buf_grow(tgt, src->size + (src->size >> 4) + 1) < 0) + return -1; + tgt->size = 0; + + for (; next; scan = next + 1, next = memchr(scan, '\n', end - scan)) { + size_t copylen = next - scan; + /* don't convert existing \r\n to \r\r\n */ + size_t extralen = (next > start && next[-1] == '\r') ? 1 : 2; + size_t needsize = tgt->size + copylen + extralen + 1; + + if (tgt->asize < needsize && git_buf_grow(tgt, needsize) < 0) + return -1; + + if (next > scan) { + memcpy(tgt->ptr + tgt->size, scan, copylen); + tgt->size += copylen; + } + if (extralen == 2) + tgt->ptr[tgt->size++] = '\r'; + tgt->ptr[tgt->size++] = '\n'; + } + + return git_buf_put(tgt, scan, end - scan); +} + int git_buf_text_common_prefix(git_buf *buf, const git_strarray *strings) { size_t i; diff --git a/src/buf_text.h b/src/buf_text.h index 458ee33c9..58e4e26a7 100644 --- a/src/buf_text.h +++ b/src/buf_text.h @@ -55,6 +55,20 @@ GIT_INLINE(int) git_buf_text_puts_escape_regex(git_buf *buf, const char *string) */ extern void git_buf_text_unescape(git_buf *buf); +/** + * Replace all \r\n with \n (or do nothing if no \r\n are found) + * + * @return 0 on success, GIT_ENOTFOUND if no \r\n, -1 on memory error + */ +extern int git_buf_text_crlf_to_lf(git_buf *tgt, const git_buf *src); + +/** + * Replace all \n with \r\n (or do nothing if no \n are found) + * + * @return 0 on success, GIT_ENOTFOUND if no \n, -1 on memory error + */ +extern int git_buf_text_lf_to_crlf(git_buf *tgt, const git_buf *src); + /** * Fill buffer with the common prefix of a array of strings * diff --git a/src/checkout.c b/src/checkout.c index e52649aec..5a2698e41 100644 --- a/src/checkout.c +++ b/src/checkout.c @@ -23,6 +23,7 @@ #include "blob.h" #include "diff.h" #include "pathspec.h" +#include "buf_text.h" /* See docs/checkout-internals.md for more information */ diff --git a/src/crlf.c b/src/crlf.c index cd6d9825f..81268da83 100644 --- a/src/crlf.c +++ b/src/crlf.c @@ -9,6 +9,7 @@ #include "fileops.h" #include "hash.h" #include "filter.h" +#include "buf_text.h" #include "repository.h" #include "git2/attr.h" #include "git2/blob.h" @@ -105,35 +106,6 @@ static int crlf_load_attributes(struct crlf_attrs *ca, git_repository *repo, con return -1; } -static int drop_crlf(git_buf *dest, const git_buf *source) -{ - const char *scan = source->ptr, *next; - const char *scan_end = git_buf_cstr(source) + git_buf_len(source); - - /* Main scan loop.

There are two core things fixed here: 1. When you had an ignore like "/bin" which is rooted at the top of your tree, instead of immediately adding the "bin/" entry as an ignored item in the diff, we were returning all of the direct descendants of the directory as ignored items. This changes things to immediately ignore the directory. Note that this effects the behavior in test_status_ignore__subdirectories so that we no longer exactly match core gits ignore behavior, but the new behavior probably makes more sense (i.e. we now will include an ignored directory inside an untracked directory that we previously would have left off). 2. When a submodule only contained working directory changes, the diff code was always considering it unmodified which was just an outright bug. The HEAD SHA of the submodule matches the SHA in the parent repo index, and since the SHAs matches, the diff code was overwriting the actual status with UNMODIFIED. These fixes broke existing tests test_diff_workdir__submodules and test_status_ignore__subdirectories but looking it over, I actually think the new results are correct and the old results were wrong. @nulltoken had actually commented on the subdirectory ignore issue previously. I also included in the tests some debugging versions of the shared iteration callback routines that print status or diff information. These aren't used actively in the tests, but can be quickly swapped in to test code to give a better picture of what is being scanned in some of the complex test scenarios. --- src/diff.c | 28 +++++++++++----- tests-clar/diff/diff_helpers.c | 10 ++++++ tests-clar/diff/diff_helpers.h | 5 +++ tests-clar/diff/workdir.c | 25 ++++++++++++--- tests-clar/status/ignore.c | 66 +++++++++++++++++++++++++++++--------- tests-clar/status/status_helpers.c | 48 +++++++++++++++++++++++++++ tests-clar/status/status_helpers.h | 4 +++ tests-clar/status/submodules.c | 51 +++++++++++++++++++++++++++++ 8 files changed, 209 insertions(+), 28 deletions(-) diff --git a/src/diff.c b/src/diff.c index 61fd18d89..7152683e7 100644 --- a/src/diff.c +++ b/src/diff.c @@ -572,7 +572,13 @@ static int maybe_modified( return -1; use_noid = &noid; } - if (omode == nmode && git_oid_equal(&oitem->oid, use_noid)) + + /* if oid matches, then mark unmodified (except submodules, where + * the filesystem content may be modified even if the oid still + * matches between the index and the workdir HEAD) + */ + if (omode == nmode && !S_ISGITLINK(omode) && + git_oid_equal(&oitem->oid, use_noid)) status = GIT_DELTA_UNMODIFIED; } @@ -725,14 +731,20 @@ int git_diff__from_iterators( recurse_into_dir = false; } - if (contains_oitem || recurse_into_dir) { - /* if this directory is ignored, remember it as the - * "ignore_prefix" for processing contained items - */ - if (delta_type == GIT_DELTA_UNTRACKED && - git_iterator_current_is_ignored(new_iter)) - git_buf_sets(&ignore_prefix, nitem->path); + /* if directory is ignored, remember ignore_prefix */ + if ((contains_oitem || recurse_into_dir) && + delta_type == GIT_DELTA_UNTRACKED && + git_iterator_current_is_ignored(new_iter)) + { + git_buf_sets(&ignore_prefix, nitem->path); + delta_type = GIT_DELTA_IGNORED; + /* skip recursion if we've just learned this is ignored */ + if (DIFF_FLAG_ISNT_SET(diff, GIT_DIFF_RECURSE_IGNORED_DIRS)) + recurse_into_dir = false; + } + + if (contains_oitem || recurse_into_dir) { /* advance into directory */ error = git_iterator_advance_into(&nitem, new_iter); diff --git a/tests-clar/diff/diff_helpers.c b/tests-clar/diff/diff_helpers.c index a1f75ce39..19c005e2e 100644 --- a/tests-clar/diff/diff_helpers.c +++ b/tests-clar/diff/diff_helpers.c @@ -42,6 +42,16 @@ int diff_file_cb( return 0; } +int diff_print_file_cb( + const git_diff_delta *delta, + float progress, + void *payload) +{ + fprintf(stderr, "%c %s\n", + git_diff_status_char(delta->status), delta->old_file.path); + return diff_file_cb(delta, progress, payload); +} + int diff_hunk_cb( const git_diff_delta *delta, const git_diff_range *range, diff --git a/tests-clar/diff/diff_helpers.h b/tests-clar/diff/diff_helpers.h index a43847b79..674fd8e19 100644 --- a/tests-clar/diff/diff_helpers.h +++ b/tests-clar/diff/diff_helpers.h @@ -30,6 +30,11 @@ extern int diff_file_cb( float progress, void *cb_data); +extern int diff_print_file_cb( + const git_diff_delta *delta, + float progress, + void *cb_data); + extern int diff_hunk_cb( const git_diff_delta *delta, const git_diff_range *range, diff --git a/tests-clar/diff/workdir.c b/tests-clar/diff/workdir.c index f67f09ae8..fc95cf8b4 100644 --- a/tests-clar/diff/workdir.c +++ b/tests-clar/diff/workdir.c @@ -953,16 +953,31 @@ void test_diff_workdir__submodules(void) cl_git_pass(git_diff_foreach( diff, diff_file_cb, diff_hunk_cb, diff_line_cb, &exp)); - /* the following differs from "git diff 873585" by two "untracked" file - * because the diff list includes the "not" and "not-submodule" dirs which - * are not displayed in the text diff. + /* so "git diff 873585" returns: + * M .gitmodules + * A just_a_dir/contents + * A just_a_file + * A sm_added_and_uncommited + * A sm_changed_file + * A sm_changed_head + * A sm_changed_index + * A sm_changed_untracked_file + * M sm_missing_commits + * A sm_unchanged + * which is a little deceptive because of the difference between the + * "git diff " results from "git_diff_tree_to_workdir".
