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. These cases were: * builtin/credential-cache.c * builtin/pull.c * builtin/send-pack.c Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

"cd sub && git grep -f patterns" tried to read "patterns" file at the top level of the working tree; it has been corrected to read "sub/patterns" instead. * jc/grep-f-relative-to-cwd: grep: -f <path> is relative to $cwd

Since 3e230fa1b2 (grep: use parseopt, 2009-05-07) git grep has been accepting the option --no-or. It does the same as --or: nothing. That's confusing and unintended. Forbid negating --or. Signed-off-by: René Scharfe <l.s.r@web.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2023-09-06grep: use OPT_INTEGER_F for --max-depthRené Scharfe
a91f453f64 (grep: Add --max-depth option., 2009-07-22) added the option --max-depth, defining it using a positional struct option initializer of type OPTION_INTEGER. It also sets defval to 1 for some reason, but that value would only be used if the flag PARSE_OPT_OPTARG was given. Use the macro OPT_INTEGER_F instead to standardize the definition and specify only the necessary values. This also normalizes argh to N_("n") as a side-effect, which is OK.

The tree_entry_interesting() function takes base_offset, allowing its callers to potentially pass a non-zero number to skip the early part of the path string.

alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for dynamic array allocation. Moving these macros to git-compat-util.h with the other alloc macros focuses alloc.[ch] to allocation for Git objects and additionally allows us to remove inclusions to alloc.h from files that solely used the above macros.

2023-06-29config: pass kvi to die_bad_number()Glen Choo
Plumb "struct key_value_info" through all code paths that end in die_bad_number(), which lets us remove the helper functions that read analogous values from "struct config_reader". As a result, nothing reads config_reader.config_kvi any more, so remove that too. In config.c, this requires changing the signature of git_configset_get_value() to 'return' "kvi" in an out parameter so that git_configset_get_<type>() can pass it to git_config_<type>(). Only numeric types will use "kvi", so for non-numeric types (e.g. git_configset_get_string()), pass NULL to indicate that the out parameter isn't needed. Outside of config.c, config callbacks now need to pass "ctx->kvi" to any of the git_config_<type>() functions that parse a config string into a number type. Included is a .cocci patch to make that refactor. The only exceptional case is builtin/config.c, where git_config_<type>() is called outside of a config callback (namely, on user-provided input), so config source information has never been available. In this case, die_bad_number() defaults to a generic, but perfectly descriptive message. Let's provide a safe, non-NULL for "kvi" anyway, but make sure not to change the message.

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.

2022-09-23builtin/grep.c: integrate with sparse indexShaoxuan Yuan
Turn on sparse index and remove ensure_full_index(). Before this patch, `git-grep` utilizes the ensure_full_index() method to expand the index and search all the entries. Because this method requires walking all the trees and constructing the index, it is the slow part within the whole command. To achieve better performance, this patch uses grep_tree() to search the sparse directory entries and get rid of the ensure_full_index() method. Why grep_tree() is a better choice over ensure_full_index()? 1) grep_tree() is as correct as ensure_full_index(). grep_tree() looks into every sparse-directory entry (represented by a tree) recursively when looping over the index, and the result of doing so matches the result of expanding the index. 2) grep_tree() utilizes pathspecs to limit the scope of searching. ensure_full_index() always expands the index, which means it will always walk all the trees and blobs in the repo without caring if the user only wants a subset of the content, i.e. using a pathspec. On the other hand, grep_tree() will only search the contents that match the pathspec, and thus possibly walking fewer trees. 3) grep_tree() does not construct and copy back a new index, while ensure_full_index() does. This also saves some time. ---------------- Performance test - Summary: p2000 tests demonstrate a ~71% execution time reduction for `git grep --cached bogus -- "f2/f1/f1/*"` using tree-walking logic. However, notice that this result varies depending on the pathspec given. See below "Command used for testing" for more details. Test HEAD~ HEAD ------------------------------------------------------- 2000.78: git grep ... (full-v3) 0.35 0.39 (≈) 2000.79: git grep ... (full-v4) 0.36 0.30 (≈) 2000.80: git grep ... (sparse-v3) 0.88 0.23 (-73.8%) 2000.81: git grep ... (sparse-v4) 0.83 0.26 (-68.6%) - Command used for testing: git grep --cached bogus -- "f2/f1/f1/*" The reason for specifying a pathspec is that, if we don't specify a pathspec, then grep_tree() will walk all the trees and blobs to find the pattern, and the time consumed doing so is not too different from using the original ensure_full_index() method, which also spends most of the time walking trees. However, when a pathspec is specified, this latest logic will only walk the area of trees enclosed by the pathspec, and the time consumed is reasonably a lot less. Generally speaking, because the performance gain is acheived by walking less trees, which are specified by the pathspec, the HEAD time v.s. HEAD~ time in sparse-v[3|4], should be proportional to "pathspec enclosed area" v.s. "all area", respectively. Namely, the wider the <pathspec> is encompassing, the less the performance difference between HEAD~ and HEAD, and vice versa. That is, if we don't specify a pathspec, the performance difference [1] is indistinguishable: both methods walk all the trees and take generally same amount of time (even with the index construction time included for ensure_full_index()).

This patch adds a command line option analogous to that of GNU grep(1)'s -m / --max-count, which users might already be used to. This makes it possible to limit the amount of matches shown in the output while keeping the functionality of other options such as -C (show code context) or -p (show containing function), which would be difficult to do with a shell pipeline (e.g. head(1)).

2022-02-16grep: simplify config parsing and option parsingÆvar Arnfjörð Bjarmason
Simplify the parsing of "grep.patternType" and "grep.extendedRegexp". This changes no behavior, but gets rid of complex parsing logic that isn't needed anymore. When "grep.patternType" was introduced in 84befcd0a4a (grep: add a grep.patternType configuration setting, 2012-08-03) we promised that: 1. You can set "grep.patternType", and "[setting it to] 'default' will return to the default matching behavior". In that context "the default" meant whatever the configuration system specified before that change, i.e. via grep.extendedRegexp. 2. We'd support the existing "grep.extendedRegexp" option, but ignore it when the new "grep.patternType" option is set. We said we'd only ignore the older "grep.extendedRegexp" option "when the `grep.patternType` option is set to a value other than 'default'". In a preceding commit we changed grep_config() to be called after grep_init(), which means that much of the complexity here can go away. As before both "grep.patternType" and "grep.extendedRegexp" are last-one-wins variable, with "grep.extendedRegexp" yielding to "grep.patternType", except when "grep.patternType=default". Note that as the previously added tests indicate this cannot be done on-the-fly as we see the config variables, without introducing more state keeping. I.e. if we see: -c grep.extendedRegexp=false -c grep.patternType=default -c extendedRegexp=true We need to select ERE, since grep.patternType=default unselects that variable, which normally has higher precedence, but we also need to select BRE in cases of: -c grep.extendedRegexp=true \ -c grep.extendedRegexp=false Which would not be the case for this, which select ERE: -c grep.patternType=extended \ -c grep.extendedRegexp=false Therefore we cannot do this on-the-fly in grep_config without also introducing tracking variables for not only the pattern type, but what the source of that pattern type was. So we need to decide on the pattern after our config was fully parsed. Let's do that by deferring the decision on the pattern type until it's time to compile it in compile_regexp(). By that time we've not only parsed the config, but also handled the command-line options. Those will set "opt.pattern_type_option" (*not* "opt.extended_regexp_option"!). At that point all we need to do is see if "grep.patternType" was UNSPECIFIED in the end (including an explicit "=default"), if so we'll use the "grep.extendedRegexp" configuration, if any. See my 07a3d411739 (grep: remove regflags from the public grep_opt API, 2017-06-29) for addition of the two comments being removed here, i.e. the complexity noted in that commit is now going away. 1. https://lore.kernel.org/git/patch-v8-09.10-c211bb0c69d-20220118T155211Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2022-02-16grep API: call grep_config() after grep_init()Ævar Arnfjörð Bjarmason
The grep_init() function used the odd pattern of initializing the passed-in "struct grep_opt" with a statically defined "grep_defaults" struct, which would be modified in-place when we invoked grep_config(). So we effectively (b) initialized config, (a) then defaults, (c) followed by user options. Usually those are ordered as "a", "b" and "c" instead. As the comments being removed here show the previous behavior needed to be carefully explained as we'd potentially share the populated configuration among different instances of grep_init(). In practice we didn't do that, but now that it can't be a concern anymore let's remove those comments. This does not change the behavior of any of the configuration variables or options. That would have been the case if we didn't move around the grep_config() call in "builtin/log.c". But now that we call "grep_config" after "git_log_config" and "git_format_config" we'll need to pass in the already initialized "struct grep_opt *". See 6ba9bb76e02 (grep: copy struct in one fell swoop, 2020-11-29) and 7687a0541e0 (grep: move the configuration parsing logic to grep.[ch], 2012-10-09) for the commits that added the comments.

2022-02-16grep.c: don't pass along NULL callback valueÆvar Arnfjörð Bjarmason
Change grep_cmd_config() to stop passing around the always-NULL "cb" value. When this code was added in 7e8f59d577e (grep: color patterns in output, 2009-03-07) it was non-NULL, but when that changed in 15fabd1bbd4 (builtin/grep.c: make configuration callback more reusable, 2012-10-09) this code was left behind. In a subsequent change I'll start using the "cb" value, this will make it clear which functions we call need it, and which don't.

2022-02-16built-ins: trust the "prefix" from run_builtin()Ævar Arnfjörð Bjarmason
Change code in "builtin/grep.c" and "builtin/ls-tree.c" to trust the "prefix" passed from "run_builtin()". The "prefix" we get from setup.c is either going to be NULL or a string of length >0, never "". So we can drop the "prefix && *prefix" checks added for "builtin/grep.c" in 0d042fecf2f (git-grep: show pathnames relative to the current directory, 2006-08-11), and for "builtin/ls-tree.c" in a69dd585fca (ls-tree: chomp leading directories when run from a subdirectory, 2005-12-23). As seen in code in revision.c that was added in cd676a51367 (diff --relative: output paths as relative to the current subdirectory, 2008-02-12) we already have existing code that does away with this assertion. This makes it easier to reason about a subsequent change to the "prefix_length" code in grep.c in a subsequent commit, and since we're going to the trouble of doing that let's leave behind an assert() to promise this to any future callers. For "builtin/grep.c" it would be painful to pass the "prefix" down the callchain of: cmd_grep -> grep_tree -> grep_submodule -> grep_cache -> grep_oid -> grep_source_name So for the code that needs it in grep_source_name() let's add a "grep_prefix" variable similar to the existing "ls_tree_prefix". While at it let's move the code in cmd_ls_tree() around so that we assign to the "ls_tree_prefix" right after declaring the variables, and stop assigning to "prefix". We only subsequently used that variable later in the function after clobbering it. Let's just use our own "grep_prefix" instead. Let's also add an assert() in git.c, so that we'll make this promise about the "prefix" to any current and future callers, as well as to any readers of the code. Code history: * The strlen() in "grep.c" hasn't been used since 493b7a08d80 (grep: accept relative paths outside current working directory, 2009-09-05). When that code was added in 0d042fecf2f (git-grep: show pathnames relative to the current directory, 2006-08-11) we used the length. But since 493b7a08d80 we haven't used it for anything except a boolean check that we could have done on the "prefix" member itself.

2021-10-23grep: fix a "path_list" memory leakÆvar Arnfjörð Bjarmason
Free the "path_list" used in builtin/grep.c, it was declared as STRING_LIST_INIT_NODUP, let's change it to a STRING_LIST_INIT_DUP since an early user in cmd_grep() appends a string passed via parse-options.c to it, which needs to be duplicated. Let's then convert the remaining callers to use string_list_append_nodup() instead, allowing us to free the list. This makes all the tests in t7811-grep-open.sh pass, 6/10 would fail before this change. The only remaining failure would have been due to a stray "git checkout" (which still leaks memory). In this case we can use a "git reset --hard" instead, so let's do that, and move the test_when_finished() above the code that would modify the relevant file.

Currently, struct repository objects corresponding to submodules are allocated on the stack in grep_submodule().

grep_source_init() can create "struct grep_source" objects and, depending on the value of the type passed, some void-pointer parameters have different meanings.

2021-07-01dir.[ch]: replace dir_init() with DIR_INITÆvar Arnfjörð Bjarmason
Remove the dir_init() function and replace it with a DIR_INIT macro. In many cases in the codebase we need to initialize things with a function for good reasons, e.g. needing to call another function on initialization. The "dir_init()" function was not one such case, and could trivially be replaced with a more idiomatic macro initialization pattern. The only place where we made use of its use of memset() was in dir_clear() itself, which resets the contents of an an existing struct pointer. Let's use the new "memcpy() a 'blank' struct on the stack" idiom to do that reset. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
