Back in prehistoric times, our decision on whether or not to show color by default relied on using a config callback that either did or didn't load color config like color.diff. When we introduced color.ui, we put it in the same boat: commands had to manually respect it by using git_color_config() or its git_color_default_config() convenience wrapper. But in 4c7f1819 (make color.ui default to 'auto', 2013-06-10), that changed. Since then, we default color.ui to auto in all programs, meaning that even plumbing commands like "git diff-tree --pretty" might colorize the output. Nobody seems to have complained in the intervening years, presumably because the "is stdout a tty" check does a good job of catching the right cases. But that leaves an interesting curiosity: color.ui defaults to auto even in plumbing, but you can't actually _disable_ the color via config. So if you really hate color and set "color.ui" to false, diff-tree will still show color (but porcelain like git-diff won't). Nobody noticed that either, probably because very few people disable color. One could argue that the plumbing should _always_ disable color unless an explicit --color option is given on the command line. But in practice, this creates a lot of complications for scripts which do want plumbing to show user-visible output. They can't just pass "--color" blindly; they need to check the user's config and decide what to send. Given that nobody has complained about the current behavior, let's assume it's a good path, and follow it to its conclusion: supporting color.ui everywhere. Note that you can create havoc by setting color.ui=always in your config, but that's more or less already the case. We could disallow it entirely, but it is handy for one-offs like: git -c color.ui=always foo >not-a-tty when "foo" does not take a --color option itself.

Refactor calls to the grep machinery to always pass opt.ignore_case & opt.extended_regexp_option instead of setting the equivalent regflags bits. The bug fixed when making -i work with -P in commit 9e3cbc59 ("log: make --regexp-ignore-case work with --perl-regexp", 2017-05-20) was really just plastering over the code smell which this change fixes. The reason for adding the extensive commentary here is that I discovered some subtle complexity in implementing this that really should be called out explicitly to future readers. Before this change we'd rely on the difference between `extended_regexp_option` and `regflags` to serve as a membrane between our preliminary parsing of grep.extendedRegexp and grep.patternType, and what we decided to do internally. Now that those two are the same thing, it's necessary to unset `extended_regexp_option` just before we commit in cases where both of those config variables are set. See 84befcd0 ("grep: add a grep.patternType configuration setting", 2012-08-03) for the code and documentation related to that. The explanation of why the if/else branches in grep_commit_pattern_type() are ordered the way they are exists in that commit message, but I think it's worth calling this subtlety out explicitly with a comment for future readers. Even though grep_commit_pattern_type() is the only caller of grep_set_pattern_type_option() it's simpler to reset the extended_regexp_option flag in the latter, since 2/3 branches in the former would otherwise need to reset it, this way we can do it in one place.

In builtin/grep.c we parse the config before evaluating the command line options. This makes the task of teaching grep to respect the new config option 'submodule.recurse' very easy by just parsing that option. As an alternative I had implemented a similar structure to treat submodules as the fetch/push command have, including * aligning the meaning of the 'recurse_submodules' to possible submodule values RECURSE_SUBMODULES_* as defined in submodule.h. * having a callback to parse the value and * reacting to the RECURSE_SUBMODULES_DEFAULT state that was the initial state. However all this is not needed for a true boolean value, so let's keep it simple. However this adds another place where "submodule.recurse" is parsed.

Skip the administrative overhead of using pthreads when only using one thread. Instead take the non-threaded path which would be taken under NO_PTHREADS. The threading support was initially added in commit 5b594f45 ("Threaded grep", 2010-01-25) with a hardcoded compile-time number of 8 threads. Later the number of threads was made configurable in commit 89f09dd3 ("grep: add --threads=<num> option and grep.threads configuration", 2015-12-15). That change did not add any special handling for --threads=1. Now we take a slightly faster path by skipping thread handling entirely when 1 thread is requested.

Change the pattern compilation logic under threading so that grep doesn't compile a pattern it never ends up using on the non-threaded code path, only to compile it again N times for N threads which will each use their own copy, ignoring the initially compiled pattern. This redundant compilation dates back to the initial introduction of the threaded grep in commit 5b594f45 ("Threaded grep", 2010-01-25). There was never any reason for doing this redundant work other than an oversight in the initial commit. Jeff King suggested on-list in <20170414212325.fefrl3qdjigwyitd@sigill.intra.peff.net> that this might be needed to check the pattern for sanity before threaded execution commences. That's not the case. The pattern is compiled under threading in start_threads() before any concurrent execution has started by calling pthread_create(), so if the pattern contains an error we still do the right thing. I.e. die with one error before any threaded execution has commenced, instead of e.g. spewing out an error for each N threads, which could be a regression a change like this might inadvertently introduce. This change is not meant as an optimization, any performance gains from this are in the hundreds to thousands of nanoseconds at most. If we wanted more performance here we could just re-use the compiled patterns in multiple threads (regcomp(3) is thread-safe), or partially re-use them and the associated structures in the case of later PCRE JIT changes. Rather, it's just to make the code easier to reason about. It's confusing to debug this under threading & non-threading when the threading codepaths redundantly compile a pattern which is never used. The reason the patterns are recompiled is as a side-effect of duplicating the whole grep_opt structure, which is not thread safe, writable, and munged during execution. The grep_opt structure then points to the grep_pat structure where pattern or patterns are stored. I looked into e.g. splitting the API into some "do & alloc threadsafe stuff", "spawn thread", "do and alloc non-threadsafe stuff", but the execution time of grep_opt_dup() & pattern compilation is trivial compared to actually executing the grep, so there was no point. Even with the more expensive JIT changes to follow the most expensive PCRE patterns take something like 0.0X milliseconds to compile at most[1]. The undocumented --debug mode added in commit 17bf35a3 ("grep: teach --debug option to dump the parse tree", 2012-09-13) still works properly with this change. It only emits debugging info during pattern compilation, which is now dumped by the pattern compiled just before the first thread is started. 1. http://sljit.sourceforge.net/pcre.htmlSigned-off-by: NÆvar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Change the grep_{lock,unlock} functions to assert that num_threads is true, instead of only locking & unlocking the pthread mutex lock when it is. These functions are never called when num_threads isn't true, this logic has gone through multiple iterations since the initial introduction of grep threading in commit 5b594f45 ("Threaded grep", 2010-01-25), but ever since then they'd only be called if num_threads was true, so this check made the code confusing to read. Replace the check with an assertion, so that it's clear to the reader that this code path is never taken unless we're spawning threads.

Add a die(...) to a default case for the switch statement selecting between grep pattern types under --recurse-submodules. Normally this would be caught by -Wswitch, but the grep_pattern_type type is converted to int by going through parse_options(). Changing the argument type passed to compile_submodule_options() won't work, the value will just get coerced. The -Wswitch-default warning will warn about it, but that produces a lot of noise across the codebase, this potential issue would be drowned in that noise. Thus catching this at runtime is the least bad option. This won't ever trigger in practice, but if a new pattern type were to be added this catches an otherwise silent bug during development. See commit 0281e487 ("grep: optionally recurse into submodules", 2016-12-16) for the initial addition of this code.

When a sha1 lookup returns the tree path via "struct object_context", it just copies it into a fixed-size buffer. This means the result can be truncated, and it means our "struct object_context" consumes a lot of stack space. Instead, let's allocate a string on the heap. Because most callers don't care about this information, we'll avoid doing it by default (so they don't all have to start calling free() on the result). There are basically two options for the caller to signal to us that it's interested: 1. By setting a pointer to storage in the object_context. 2. By passing a flag in another parameter. Doing (1) would match the way that sha1_object_info_extended() works. But it would mean that every caller would have to initialize the object_context, which they don't currently have to do. This patch does (2), and adds a new bit to the function's flags field. All of the callers that look at the "path" field are updated to pass the new flag.

Commit 0281e487 ("grep: optionally recurse into submodules") added functions grep_submodule() and grep_submodule_launch() which use "struct work_item" which is defined only when thread support is available. The original implementation of grep_submodule() used the "struct work_item" in order to gain access to a strbuf to store its output which was to be printed at a later point in time. This differs from how both grep_file() and grep_sha1() handle their output. This patch eliminates the reliance on the "struct work_item" and instead opts to use the output function stored in the output field of the "struct grep_opt" object directly, making it behave similarly to both grep_file() and grep_sha1().

When using the --recurse-submodules flag with a relative pathspec which includes "..", an error is produced inside the child process spawned for a submodule. When creating the pathspec struct in the child, the ".." is interpreted to mean "go up a directory" which causes an error stating that the path ".." is outside of the repository. While it is true that ".." is outside the scope of the submodule, it is confusing to a user who originally invoked the command where ".." was indeed still inside the scope of the superproject. Since the child process launched for the submodule has some context that it is operating underneath a superproject, this error could be avoided. This patch fixes the bug by passing the 'prefix' to the child process. Now each child process that works on a submodule has two points of reference to the superproject: (1) the 'super_prefix' which is the path from the root of the superproject down to root of the submodule and (2) the 'prefix' which is the path from the root of the superproject down to the directory where the user invoked the git command. With these two pieces of information a child process can correctly interpret the pathspecs provided by the user as well as being able to properly format its output relative to the directory the user invoked the original command from.

git-grep has always disallowed grepping in a tree (as opposed to the working directory) with both --untracked and --no-index. But we traditionally did so by first collecting the revs, and then complaining when any were provided. The --no-index option recently learned to detect revs much earlier. This has two user-visible effects: - we don't bother to resolve revision names at all. So when there's a rev/path ambiguity, we always choose to treat it as a path. - likewise, when you do specify a revision without "--", the error you get is "no such path" and not "--untracked cannot be used with revs". The rationale for doing this with --no-index is that it is meant to be used outside a repository, and so parsing revs at all does not make sense. This patch gives --untracked the same treatment. While it _is_ meant to be used in a repository, it is explicitly about grepping the non-repository contents. Telling the user "we found a rev, but you are not allowed to use revs" is not really helpful compared to "we treated your argument as a path, and could not find it".

We disallow the use of revisions with --no-index, but we don't actually check and complain until well after we've parsed the revisions. This is the cause of a few problems: 1. We shouldn't be calling get_sha1() at all when we aren't in a repository, as it might access the ref or object databases. For now, this should generally just return failure, but eventually it will become a BUG(). 2. When there's a "--" disambiguator and you're outside a repository, we'll complain early with "unable to resolve revision". But we can give a much more specific error. 3. When there isn't a "--" disambiguator, we still do the normal rev/path checks. This is silly, as we know we cannot have any revs with --no-index. Everything we see must be a path. Outside of a repository this doesn't matter (since we know it won't resolve), but inside one, we may complain unnecessarily if a filename happens to also match a refname. This patch skips the get_sha1() call entirely in the no-index case, and behaves as if it failed (with the exception of giving a better error message).

If we see "git grep pattern rev -- file" then we apply the usual rev/pathspec disambiguation rules: any "rev" before the "--" must be a revision, and we do not need to apply the verify_non_filename() check. But there are two bugs here: 1. We keep a seen_dashdash flag to handle this case, but we set it in the same left-to-right pass over the arguments in which we parse "rev". So when we see "rev", we do not yet know that there is a "--", and we mistakenly complain if there is a matching file. We can fix this by making a preliminary pass over the arguments to find the "--", and only then checking the rev arguments. 2. If we can't resolve "rev" but there isn't a dashdash, that's OK. We treat it like a path, and complain later if it doesn't exist. But if there _is_ a dashdash, then we know it must be a rev, and should treat it as such, complaining if it does not resolve. The current code instead ignores it and tries to treat it like a path. This patch fixes both bugs, and tries to comment the parsing flow a bit better. It adds tests that cover the two bugs, but also some related situations (which already worked, but this confirms that our fixes did not break anything).

We loop over the arguments, but every branch of the loop hits either a "continue" or a "break". Surely we can make this simpler. The final conditional is: if (arg is a rev) { ... handle rev ... continue; } break; We can rewrite this as: if (arg is not a rev) break; ... handle rev ...

"git grep" has always tried to first interpret "--" as a rev for at least a few years, but this issue was upgraded from a pessimization to a bug in commit 59332d13 ("Resurrect "git grep --no-index"", 2010-02-06), which calls get_sha1 regardless of whether --no-index was specified. This bug appeared to be benign until commit b1ef400e ("setup_git_env: avoid blind fall-back to ".git"", 2016-10-20) when Git was taught to die in this situation. (This "git grep" bug appears to be one of the bugs that commit b1ef400e is meant to flush out.) Therefore, always interpret "--" as signaling the end of options, instead of trying to interpret it as a rev first.

Originally, we set up the threads for grep before parsing the non-option arguments. In 53b8d931 (grep: disable threading in non-worktree case, 2011-12-12), the thread code got bumped lower in the function because it now needed to know whether we got any revision arguments. That put a big block of code in between the parsing of revs and the parsing of pathspecs, both of which share some loop variables. That makes it harder to read the code than the original, where the shared loops were right next to each other. Let's bump the thread initialization until after all of the parsing is done.

If a submodule was renamed at any point since it's inception then if you were to try and grep on a commit prior to the submodule being moved, you wouldn't be able to find a working directory for the submodule since the path in the past is different from the current path. This patch teaches grep to find the .git directory for a submodule in the parents .git/modules/ directory in the event the path to the submodule in the commit that is being searched differs from the state of the currently checked out commit. If found, the child process that is spawned to grep the submodule will chdir into its gitdir instead of a working directory. In order to override the explicit setting of submodule child process's gitdir environment variable (which was introduced in '10f5c526') `GIT_DIR_ENVIORMENT` needs to be pushed onto child process's env_array. This allows the searching of history from a submodule's gitdir, rather than from a working directory.

Teach grep to recursively search in submodules when provided with a <tree> object. This allows grep to search a submodule based on the state of the submodule that is present in a commit of the super project. When grep is provided with a <tree> object, the name of the object is prefixed to all output. In order to provide uniformity of output between the parent and child processes the option `--parent-basename` has been added so that the child can preface all of it's output with the name of the parent's object instead of the name of the commit SHA1 of the submodule. This changes output from the command `git grep -e. -l --recurse-submodules HEAD` from: HEAD:file <commit sha1 of submodule>:sub/file to: HEAD:file HEAD:sub/file Signed-off-by: NBrandon Williams <bmwill@google.com> Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Allow grep to recognize submodules and recursively search for patterns in each submodule. This is done by forking off a process to recursively call grep on each submodule. The top level --super-prefix option is used to pass a path to the submodule which can in turn be used to prepend to output or in pathspec matching logic. Recursion only occurs for submodules which have been initialized and checked out by the parent project. If a submodule hasn't been initialized and checked out it is simply skipped. In order to support the existing multi-threading infrastructure in grep, output from each child process is captured in a strbuf so that it can be later printed to the console in an ordered fashion. To limit the number of theads that are created, each child process has half the number of threads as its parents (minimum of 1), otherwise we potentailly have a fork-bomb.

This reverts commit 4d552005 (grep: make it clear i-t-a entries are ignored, 2015-12-27) and adds an alternative fix to maintain the -L --cached behavior. 4d552005 caused 'git grep' to no longer find matches in new files in the working tree where the corresponding index entry had the "intent to add" bit set, despite the fact that these files are tracked. The content in the index of a file for which the "intent to add" bit is set is considered indeterminate and not empty. For most grep queries we want these to behave the same, however for -L --cached (files without a match) we don't want to respond positively for "intent to add" files as their contents are indeterminate. This is in contrast to files with empty contents in the index (no lines implies no matches for any grep query expression) which should be reported in the output of a grep -L --cached invocation. Add tests to cover this case and a few related cases which previously lacked coverage.
