2023-12-28Merge branch 'jc/checkout-B-branch-in-use'Junio C Hamano
"git checkout -B <branch> [<start-point>]" allowed a branch that is in use in another worktree to be updated and checked out, which might be a bit unexpected. The rule has been tightened, which is a breaking change. "--ignore-other-worktrees" option is required to unbreak you, if you are used to the current behaviour that "-B" overrides the safety. * jc/checkout-B-branch-in-use: checkout: forbid "-B <branch>" from touching a branch used elsewhere checkout: refactor die_if_checked_out() caller

Each of these were checked with gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE} to ensure that removing the direct inclusion of the header actually resulted in that header no longer being included at all (i.e. that no other header pulled it in transitively). ...except for a few cases where we verified that although the header was brought in transitively, nothing from it was directly used in that source file.

2023-12-13checkout: forbid "-B <branch>" from touching a branch used elsewhereJunio C Hamano
"git checkout -B <branch> [<start-point>]", being a "forced" version of "-b", switches to the <branch>, after optionally resetting its tip to the <start-point>, even if the <branch> is in use in another worktree, which is somewhat unexpected. Protect the <branch> using the same logic that forbids "git checkout <branch>" from touching a branch that is in use elsewhere. This is a breaking change that may deserve backward compatibliity warning in the Release Notes. The "--ignore-other-worktrees" option can be used as an escape hatch if the finger memory of existing users depend on the current behaviour of "-B".

2023-12-09config: handle NULL value when parsing non-boolsJeff King
When the config parser sees an "implicit" bool like: [core] someVariable it passes NULL to the config callback. Any callback code which expects a string must check for NULL. This usually happens via helpers like git_config_string(), etc, but some custom code forgets to do so and will segfault. These are all fairly vanilla cases where the solution is just the usual pattern of: if (!value) return config_error_nonbool(var); though note that in a few cases we have to split initializers like: int some_var = initializer(); into: int some_var; if (!value) return config_error_nonbool(var); some_var = initializer(); There are still some broken instances after this patch, which I'll address on their own in individual patches after this one.

2023-11-24orphan/unborn: fix use of 'orphan' in end-user facing messagesJunio C Hamano
"orphan branch" is not even grammatical ("orphaned branch" is), and we have been using "unborn branch" to mean the state where the HEAD points at a branch that does not yet exist. Update end-user facing messages to correct them. There are cases other random words are used (e.g., "unparented branch") but now we have a glossary entry, use the term "unborn branch" consistently.

2023-11-23checkout: refactor die_if_checked_out() callerJunio C Hamano
There is a bit dense logic to make a call to "die_if_checked_out()" while trying to check out a branch. Extract it into a helper function and give it a bit of comment to describe what is going on. The most important part of the refactoring is the separation of the guarding logic before making the call to die_if_checked_out() into the caller specific part (e.g., the logic that decides that the caller is trying to check out an existing branch) and the bypass due to the "--ignore-other-worktrees" option. The latter will be common no matter how the current or future callers decides they need this protection. Signed-off-by: Junio C Hamano <gitster@pobox.com>

2023-08-01checkout: allow "checkout -m path" to unmerge removed pathsJunio C Hamano
"git checkout -m -- path" uses the unmerge_marked_index() API, whose implementation is incapable of unresolving a path that was resolved as removed. Extend the unmerge_index() API function so that we can mark the ce_flags member of the cache entries we add to the index as unmerged, and replace use of unmerge_marked_index() with it. Now, together with its unmerge_index_entry_at() helper function, unmerge_marked_index() function is no longer called by anybody, and can safely be removed. This makes two known test failures in t2070 and t7201 to succeed. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Recreating unmerged index entries using resolve-undo data, recreating conflicted working tree files using unmerged index entries, and writing data out of unmerged index entries, make sense only when we are checking paths out of the index and not when we are checking paths out of a tree-ish. Add an extra check to make sure "--merge" and "--ours/--theirs" options are rejected when checking out from a tree-ish, update the document (especially the SYNOPSIS section) to highlight that they are incompatible, and add a few tests to make sure the combination fails.

2023-07-06Merge branch 'gc/config-context'Junio C Hamano
Reduce reliance on a global state in the config reading API. * gc/config-context: config: pass source to config_parser_event_fn_t config: add kvi.path, use it to evaluate includes config.c: remove config_reader from configsets config: pass kvi to die_bad_number() trace2: plumb config kvi config.c: pass ctx with CLI config config: pass ctx with config files config.c: pass ctx in configsets config: add ctx arg to config_fn_t urlmatch.h: use config_fn_t type config: inline git_color_default_config
2023-06-29config: add ctx arg to config_fn_tGlen Choo
Add a new "const struct config_context *ctx" arg to config_fn_t to hold additional information about the config iteration operation. config_context has a "struct key_value_info kvi" member that holds metadata about the config source being read (e.g. what kind of config source it is, the filename, etc). In this series, we're only interested in .kvi, so we could have just used "struct key_value_info" as an arg, but config_context makes it possible to add/adjust members in the future without changing the config_fn_t signature. We could also consider other ways of organizing the args (e.g. moving the config name and value into config_context or key_value_info), but in my experiments, the incremental benefit doesn't justify the added complexity (e.g. a config_fn_t will sometimes invoke another config_fn_t but with a different config value). In subsequent commits, the .kvi member will replace the global "struct config_reader" in config.c, making config iteration a global-free operation. It requires much more work for the machinery to provide meaningful values of .kvi, so for now, merely change the signature and call sites, pass NULL as a placeholder value, and don't rely on the arg in any meaningful way. Most of the changes are performed by contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every config_fn_t: - Modifies the signature to accept "const struct config_context *ctx" - Passes "ctx" to any inner config_fn_t, if needed - Adds UNUSED attributes to "ctx", if needed Most config_fn_t instances are easily identified by seeing if they are called by the various config functions. Most of the remaining ones are manually named in the .cocci patch. Manual cleanups are still needed, but the majority of it is trivial; it's either adjusting config_fn_t that the .cocci patch didn't catch, or adding forward declarations of "struct config_context ctx" to make the signatures make sense. The non-trivial changes are in cases where we are invoking a config_fn_t outside of config machinery, and we now need to decide what value of "ctx" to pass. These cases are: - trace2/tr2_cfg.c:tr2_cfg_set_fl() This is indirectly called by git_config_set() so that the trace2 machinery can notice the new config values and update its settings using the tr2 config parsing function, i.e. tr2_cfg_cb(). - builtin/checkout.c:checkout_main() This calls git_xmerge_config() as a shorthand for parsing a CLI arg. This might be worth refactoring away in the future, since git_xmerge_config() can call git_default_config(), which can do much more than just parsing. Handle them by creating a KVI_INIT macro that initializes "struct key_value_info" to a reasonable default, and use that to construct the "ctx" arg.

2023-06-21merge-ll: rename from ll-mergeElijah Newren
A long term (but rather minor) pet-peeve of mine was the name ll-merge.[ch]. I thought it made it harder to realize what stuff was related to merging when I was working on the merge machinery and trying to improve it. Further, back in d1cbe1e6d8a ("hash-ll.h: split out of hash.h to remove dependency on repository.h", 2023-04-22), we have split the portions of hash.h that do not depend upon repository.h into a "hash-ll.h" (due to the recommendation to use "ll" for "low-level" in its name[1], but which I used as a suffix precisely because of my distaste for "ll-merge"). When we discussed adding additional "*-ll.h" files, a request was made that we use "ll" consistently as either a prefix or a suffix. Since it is already in use as both a prefix and a suffix, the only way to do so is to rename some files. Besides my distaste for the ll-merge.[ch] name, let me also note that the files ll-fsmonitor.h, ll-hash.h, ll-merge.h, ll-object-store.h, ll-read-cache.h would have essentially nothing to do with each other and make no sense to group. But giving them the common "ll-" prefix would group them. Using "-ll" as a suffix thus seems just much more logical to me. Rename ll-merge.[ch] to merge-ll.[ch] to achieve this consistency, and to ensure we get a more logical grouping of files.

2023-06-21add: modify add_files_to_cache() to avoid globalsElijah Newren
The function add_files_to_cache() is used by all three of builtin/{add, checkout, commit}.c. That suggests this is common library code, and should be moved somewhere else, like read-cache.c. However, the function and its helpers made use of two global variables that made straight code movement difficult: * the_index * include_sparse The latter was perhaps more problematic since it was only accessible in builtin/add.c but was still affecting builtin/checkout.c and builtin/commit.c without this fact being very clear from the code. I'm not sure if the other two callers would want to add a `--sparse` flag similar to add.c to get non-default behavior, but exposing this dependence will help if we ever decide we do want to add such a flag. Modify add_files_to_cache() and its helpers to accept the necessary arguments instead of relying on globals.

2023-03-07parse-options: consistently allocate memory in fix_filename()Jeff King
When handling OPT_FILENAME(), we have to stick the "prefix" (if any) in front of the filename to make up for the fact that Git has chdir()'d to the top of the repository. We can do this with prefix_filename(), but there are a few special cases we handle ourselves. Unfortunately the memory allocation is inconsistent here; if we do make it to prefix_filename(), we'll allocate a string which the caller must free to avoid a leak. But if we hit our special cases, we'll return the string as-is, and a caller which tries to free it will crash. So there's no way to win. Let's consistently allocate, so that callers can do the right thing. There are now three cases to care about in the function (and hence a three-armed if/else): 1. we got a NULL input (and should leave it as NULL, though arguably this is the sign of a bug; let's keep the status quo for now and we can pick at that scab later) 2. we hit a special case that means we leave the name intact; we should duplicate the string. This includes our special "-" matching. Prior to this patch, it also included empty prefixes and absolute filenames. But we can observe that prefix_filename() already handles these, so we don't need to detect them. 3. everything else goes to prefix_filename() I've dropped the "const" from the "char **file" parameter to indicate that we're allocating, though in practice it's not really important. This is all being shuffled through a void pointer via opt->value before it hits code which ever looks at the string. And it's even a bit weird, because we are really taking _in_ a const string and using the same out-parameter for a non-const string. A better function signature would be: static char *fix_filename(const char *prefix, const char *file); but that would mean the caller dereferences the double-pointer (and the NULL check is currently handled inside this function). So I took the path of least-change here. Note that we have to fix several callers in this commit, too, or we'll break the leak-checking tests. These are "new" leaks in the sense that they are now triggered by the test suite, but these spots have always been leaky when Git is run in a subdirectory of the repository. I fixed all of the cases that trigger with GIT_TEST_PASSING_SANITIZE_LEAK. There may be others in scripts that have other leaks, but we can fix them later along with those other leaks (and again, you _couldn't_ fix them before this patch, so this is the necessary first step).

2023-02-27restore: fault --staged --worktree with merge optsAndy Koppe
The 'restore' command already rejects the --merge, --conflict, --ours and --theirs options when combined with --staged, but accepts them when --worktree is added as well. Unfortunately that doesn't appear to do anything useful. The --ours and --theirs options seem to be ignored when both --staged and --worktree are given, whereas with --merge or --conflict, the command has the same effect as if the --staged option wasn't present. So reject those options with '--staged --worktree' as well, using opts->accept_ref to distinguish restore from checkout. Add test for both '--staged' and '--staged --worktree'.

2023-01-08*: fix typos which duplicate a wordAndrei Rybak
Fix typos in code comments which repeat various words. Most of the cases are simple in that they repeat a word that usually cannot be repeated in a grammatically correct sentence. Just remove the incorrectly duplicated word in these cases and rewrap text, if needed. A tricky case is usage of "that that", which is sometimes grammatically correct. However, an instance of this in "t7527-builtin-fsmonitor.sh" doesn't need two words "that", because there is only one daemon being discussed, so replace the second "that" with "the".

2022-12-26read-tree: add "--super-prefix" option, eliminate globalÆvar Arnfjörð Bjarmason
The "--super-prefix" option to "git" was initially added in [1] for use with "ls-files"[2], and shortly thereafter "submodule--helper"[3] and "grep"[4]. It wasn't until [5] that "read-tree" made use of it. At the time [5] made sense, but since then we've made "ls-files" recurse in-process in [6], "grep" in [7], and finally "submodule--helper" in the preceding commits. Let's also remove it from "read-tree", which allows us to remove the option to "git" itself. We can do this because the only remaining user of it is the submodule API, which will now invoke "read-tree" with its new "--super-prefix" option. It will only do so when the "submodule_move_head()" function is called. That "submodule_move_head()" function was then only invoked by "read-tree" itself, but now rather than setting an environment variable to pass "--super-prefix" between cmd_read_tree() we: - Set a new "super_prefix" in "struct unpack_trees_options". The "super_prefixed()" function in "unpack-trees.c" added in [5] will now use this, rather than get_super_prefix() looking up the environment variable we set earlier in the same process. - Add the same field to the "struct checkout", which is only needed to ferry the "super_prefix" in the "struct unpack_trees_options" all the way down to the "entry.c" callers of "submodule_move_head()". Those calls which used the super prefix all originated in "cmd_read_tree()". The only other caller is the "unlink_entry()" caller in "builtin/checkout.c", which now passes a "NULL". 1. 74866d75793 (git: make super-prefix option, 2016-10-07) 2. e77aa336f11 (ls-files: optionally recurse into submodules, 2016-10-07) 3. 89c86265576 (submodule helper: support super prefix, 2016-12-08) 4. 0281e487fd9 (grep: optionally recurse into submodules, 2016-12-16) 5. 3d415425c7b (unpack-trees: support super-prefix option, 2017-01-17) 6. 188dce131fa (ls-files: use repository object, 2017-06-22) 7. f9ee2fcdfa0 (grep: recurse in-process using 'struct repository', 2017-08-02) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2022-11-21built-ins & libs & helpers: add/move destructors, fix leaksÆvar Arnfjörð Bjarmason
Fix various leaks in built-ins, libraries and a test helper here we were missing a call to strbuf_release(), string_list_clear() etc, or were calling them after a potential "return". Comments on individual changes: - builtin/checkout.c: Fix a memory leak that was introduced in [1]. A sibling leak introduced in [2] was recently fixed in [3]. As with [3] we should be using the wt_status_state_free_buffers() API introduced in [4]. - builtin/repack.c: Fix a leak that's been here since this use of "strbuf_release()" was added in a1bbc6c0176 (repack: rewrite the shell script in C, 2013-09-15). We don't use the variable for anything except this loop, so we can instead free it right afterwards. - builtin/rev-parse: Fix a leak that's been here since this code was added in 21d47835386 (Add a parseopt mode to git-rev-parse to bring parse-options to shell scripts., 2007-11-04). - builtin/stash.c: Fix a couple of leaks that have been here since this code was added in d4788af875c (stash: convert create to builtin, 2019-02-25), we strbuf_release()'d only some of the "struct strbuf" we allocated earlier in the function, let's release all of them. - ref-filter.c: Fix a leak in 482c1191869 (gpg-interface: improve interface for parsing tags, 2021-02-11), we don't use the "payload" variable that we ask parse_signature() to populate for us, so let's free it. - t/helper/test-fake-ssh.c: Fix a leak that's been here since this code was added in 3064d5a38c7 (mingw: fix t5601-clone.sh, 2016-01-27). Let's free the "struct strbuf" as soon as we don't need it anymore. 1. c45f0f525de (switch: reject if some operation is in progress, 2019-03-29) 2. 2708ce62d21 (branch: sort detached HEAD based on a flag, 2021-01-07) 3. abcac2e19fa (ref-filter.c: fix a leak in get_head_description, 2022-09-25) 4. 962dd7ebc3e (wt-status: introduce wt_status_state_free_buffers(), 2020-09-27).

2022-11-21cocci: apply "pending" index-compatibility to some "builtin/*.c"Ævar Arnfjörð Bjarmason
Apply "index-compatibility.pending.cocci" rule to "builtin/*", but exclude those where we conflict with in-flight changes. As a result some of them end up using only "the_index", so let's have them use the more narrow "USE_THE_INDEX_VARIABLE" rather than "USE_THE_INDEX_COMPATIBILITY_MACROS". Manual changes not made by coccinelle, that were squashed in: * Whitespace-wrap argument lists for repo_hold_locked_index(), repo_read_index_preload() and repo_refresh_and_write_index(), in cases where the line became too long after the transformation. * Change "refresh_cache()" to "refresh_index()" in a comment in "builtin/update-index.c". * For those whose call was followed by perror("<macro-name>"), change it to perror("<function-name>"), referring to the new function.

2022-11-21cocci & cache.h: apply variable section of "pending" index-compatibilityÆvar Arnfjörð Bjarmason
Mostly apply the part of "index-compatibility.pending.cocci" that renames the global variables like "active_nr", which are a shorthand to referencing (in that case) a struct member as "the_index.cache_nr". In doing so move more of "index-compatibility.pending.cocci" to "index-compatibility.cocci". In the case of "active_nr" we'd have a textual conflict with "ab/various-leak-fixes" in "next"[1]. Let's exclude that specific case while moving the rule over from "pending". 1. 407b94280f8 (commit: discard partial cache before (re-)reading it, 2022-11-08) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-11-21cocci & cache.h: apply a selection of "pending" index-compatibilityÆvar Arnfjörð Bjarmason
Apply a selection of rules in "index-compatibility.pending.cocci" tree-wide, and in doing so migrate them to "index-compatibility.cocci". As in preceding commits the only manual changes here are the macro removals in "cache.h", and the update to the '*.cocci" rules. The rest of the C code changes are the result of applying those updated rules. Move rules for some rarely used cache compatibility macros from "index-compatibility.pending.cocci" to "index-compatibility.cocci" and apply them.

2022-11-21cocci & cache.h: remove rarely used "the_index" compat macrosÆvar Arnfjörð Bjarmason
Since 4aab5b46f44 (Make read-cache.c "the_index" free., 2007-04-01) we've been undergoing a slow migration away from these macros, but haven't made much progress since f8adbec9fea (cache.h: flip NO_THE_INDEX_COMPATIBILITY_MACROS switch, 2019-01-24). Let's move forward a bit by changing the users of those macros that are rare enough that we can convert them in one go, and then remove the compatibility shim. The only manual change to the C code here is to "cache.h", the rest is all the result of applying the new "index-compatibility.cocci". Even though it's a one-off, let's keep the coccinelle rules for now. We'll extend them in subsequent commits, and this will help anything that's in-flight or out-of-tree to migrate.

2022-09-01git-compat-util.h: use "UNUSED", not "UNUSED(var)"Ævar Arnfjörð Bjarmason
As reported in [1] the "UNUSED(var)" macro introduced in 2174b8c75de (Merge branch 'jk/unused-annotation' into next, 2022-08-24) breaks coccinelle's parsing of our sources in files where it occurs. Let's instead partially go with the approach suggested in [2] of making this not take an argument. As noted in [1] "coccinelle" will ignore such tokens in argument lists that it doesn't know about, and it's less of a surprise to syntax highlighters. This undoes the "help us notice when a parameter marked as unused is actually use" part of 9b240347543 (git-compat-util: add UNUSED macro, 2022-08-19), a subsequent commit will further tweak the macro to implement a replacement for that functionality. 1. https://lore.kernel.org/git/220825.86ilmg4mil.gmgdl@evledraar.gmail.com/ 2. https://lore.kernel.org/git/220819.868rnk54ju.gmgdl@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
