|\ | | | | | | | | | | | | | | | | "git -c grep.patternType=extended log --basic-regexp" misbehaved because the internal API to access the grep machinery was not designed well. * jc/grep-commandline-vs-configuration: grep: further simplify setting the pattern type
| * grep: further simplify setting the pattern typeJunio C Hamano2016-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When c5c31d33 (grep: move pattern-type bits support to top-level grep.[ch], 2012-10-03) introduced grep_commit_pattern_type() helper function, the intention was to allow the users of grep API to having to fiddle only with .pattern_type_option (which can be set to "fixed", "basic", "extended", and "pcre"), and then immediately before compiling the pattern strings for use, call grep_commit_pattern_type() to have it prepare various bits in the grep_opt structure (like .fixed, .regflags, etc.). However, grep_set_pattern_type_option() helper function the grep API internally uses were left as an external function by mistake. This function shouldn't have been made callable by the users of the API. Later when the grep API was used in revision traversal machinery, the caller then mistakenly started calling the function around 34a4ae55 (log --grep: use the same helper to set -E/-F options as "git grep", 2012-10-03), instead of setting the .pattern_type_option field and letting the grep_commit_pattern_type() to take care of the details. This caused an unnecessary bug that made a configured grep.patternType take precedence over the command line options (e.g. --basic-regexp, --fixed-strings) in "git log" family of commands.

* grep: allow to use textconv filtersJeff King2013-05-10
| | | | | | | | | | | | | | | | | | | | Recently and not so recently, we made sure that log/grep type operations use textconv filters when a userfacing diff would do the same: ef90ab6 (pickaxe: use textconv for -S counting, 2012-10-28) b1c2f57 (diff_grep: use textconv buffers for add/deleted files, 2012-10-28) 0508fe5 (combine-diff: respect textconv attributes, 2011-05-23) "git grep" currently does not use textconv filters at all, that is neither for displaying the match and context nor for the actual grepping, even when requested by --textconv. Introduce an option "--textconv" which makes git grep use any configured textconv filters for grepping and output purposes. It is off by default.

| * grep: stop looking at random places for .gitattributesNguyễn Thái Ngọc Duy2012-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | grep searches for .gitattributes using "name" field in struct grep_source but that field is not real on-disk path name. For example, "grep pattern rev" fills the field with "rev:path", and Git looks for .gitattributes in the (non-existent but exploitable) path "rev:path" instead of "path". This patch passes real paths down to grep_source_load_driver() when: - grep on work tree - grep on the index - grep a commit (or a tag if it points to a commit) so that these cases look up .gitattributes at proper paths. .gitattributes lookup is disabled in all other cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our "grep" allows complex boolean expressions to be formed to match each individual line with operators like --and, '(', ')' and --not. Introduce the "--debug" option to show the parse tree to help people who want to debug and enhance it. Also "log" learns "--grep-debug" option to do the same. The command line parser to the log family is a lot more limited than the general "git grep" parser, but it has special handling for header matching (e.g. "--author"), and a parse tree is valuable when working on it. Note that "--all-match" is *not* any individual node in the parse tree. It is an instruction to the evaluator to check all the nodes in the top-level backbone have matched and reject a document as non-matching otherwise. Signed-off-by: Junio C Hamano <gitster@pobox.com>

The current values are "basic", "extended", "fixed", "perl" and "default" for setting -G, -E, -F, -P and the default behavior respectively. When grep.patternType is set to a value other than "default", the grep.extendedRegexp setting is ignored.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, patterns that contain newline characters don't match anything when given to git grep. Regular grep(1) interprets patterns as lists of newline separated search strings instead. Implement this functionality by creating and inserting extra grep_pat structures for patterns consisting of multiple lines when appending to the pattern lists. For simplicity, all pattern strings are duplicated. The original pattern is truncated in place to make it contain only the first line.

* | grep: respect diff attributes for binary-nessJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is currently no way for users to tell git-grep that a particular path is or is not a binary file; instead, grep always relies on its auto-detection (or the user specifying "-a" to treat all binary-looking files like text). This patch teaches git-grep to use the same attribute lookup that is used by git-diff. We could add a new "grep" flag, but that is unnecessarily complex and unlikely to be useful. Despite the name, the "-diff" attribute (or "diff=foo" and the associated diff.foo.binary config option) are really about describing the contents of the path. It's simply historical that diff was the only thing that cared about these attributes in the past. And if this simple approach turns out to be insufficient, we still have a backwards-compatible path forward: we can add a separate "grep" attribute, and fall back to respecting "diff" if it is unset.

* | grep: cache userdiff_driver in grep_sourceJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now, grep only uses the userdiff_driver for one thing: looking up funcname patterns for "-p" and "-W". As new uses for userdiff drivers are added to the grep code, we want to minimize attribute lookups, which can be expensive. It might seem at first that this would also optimize multiple lookups when the funcname pattern for a file is needed multiple times. However, the compiled funcname pattern is already cached in struct grep_opt's "priv" member, so multiple lookups are already suppressed.

* | grep: drop grep_buffer's "name" parameterJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before the grep_source interface existed, grep_buffer was used by two types of callers: 1. Ones which pulled a file into a buffer, and then wanted to supply the file's name for the output (i.e., git grep). 2. Ones which really just wanted to grep a buffer (i.e., git log --grep). Callers in set (1) should now be using grep_source. Callers in set (2) always pass NULL for the "name" parameter of grep_buffer. We can therefore get rid of this now-useless parameter.

* | grep: refactor the concept of "grep source" into an objectJeff King2012-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main interface to the low-level grep code is grep_buffer, which takes a pointer to a buffer and a size. This is convenient and flexible (we use it to grep commit bodies, files on disk, and blobs by sha1), but it makes it hard to pass extra information about what we are grepping (either for correctness, like overriding binary auto-detection, or for optimizations, like lazily loading blob contents). Instead, let's encapsulate the idea of a "grep source", including the buffer, its size, and where the data is coming from. This is similar to the diff_filespec structure used by the diff code (unsurprising, since future patches will implement some of the same optimizations found there). The diffstat is slightly scarier than the actual patch content. Most of the modified lines are simply replacing access to raw variables with their counterparts that are now in a "struct grep_source". Most of the added lines were taken from builtin/grep.c, which partially abstracted the idea of grep sources (for file vs sha1 sources). Instead of dropping the now-redundant code, this patch leaves builtin/grep.c using the traditional grep_buffer interface (which now wraps the grep_source interface). That makes it easy to test that there is no change of behavior (yet). Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The multi-threaded git-grep code needs to serialize access to the thread-unsafe read_sha1_file call. It does this with a mutex that is local to builtin/grep.c. Let's instead push this down into grep.c, where it can be used by both builtin/grep.c and grep.c. This will let us safely teach the low-level grep.c code tricks that involve reading from the object db. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
* | grep: make locking flag globalJeff King2012-02-02

That changed with 0579f91 (grep: enable threading with -p and -W using lazy attribute lookup, 2011-12-12), which pushed the lookup of funcname attributes (which is not thread-safe) into the low-level grep code. As a result, the low-level code learned about a new global "grep_attr_mutex" to serialize access to the attribute code. A multi-threaded caller (e.g., builtin/grep.c) is expected to initialize the mutex and set "use_threads" in the grep_opt structure. The low-level code only uses the lock if use_threads is set. However, putting the use_threads flag into the grep_opt struct is not the most logical place. Whether threading is in use is not something that matters for each call to grep_buffer, but is instead global to the whole program (i.e., if any thread is doing multi-threaded grep, every other thread, even if it thinks it is doing its own single-threaded grep, would need to use the locking). In practice, this distinction isn't a problem for us, because the only user of multi-threaded grep is "git-grep", which does nothing except call grep. This patch turns the opt->use_threads flag into a global flag. More important than the nit-picking semantic argument above is that this means that the locking functions don't need to actually have access to a grep_opt to know whether to lock. Which in turn can make adding new locks simpler, as we don't need to pass around a grep_opt. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

As a side effect of using kwset two grep tests are fixed by this patch. The first is fixed because kwset can deal with case-insensitive search containing NULs, something strcasestr cannot do. The second one is fixed because we consider patterns containing NULs as fixed strings (regcomp cannot accept patterns with NULs).

We however need to be a bit more clever when the user asks more than one "author" (or "committer"); because a commit has only one author (and one committer), they ought to be interpreted as asking for union to be useful. The current implementation simply added another author/committer pattern at the same top-level for ALL-MATCH to insist on matching all, finding nothing. Turn log --author=me --author=her \ --committer=him --committer=you \ --grep=this --grep=that into (ALL-MATCH (OR (HEADER-AUTHOR me) (HEADER-AUTHOR her)) (OR (HEADER-COMMITTER him) (HEADER-COMMITTER you)) (OR (PATTERN this) (PATTERN that))) instead.

| * enums: omit trailing comma for portabilityGary V. Vaughan2010-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX 5.1 fails to compile git. enum style is inconsistent already, with some enums declared on one line, some over 3 lines with the enum values all on the middle line, sometimes with 1 enum value per line... and independently of that the trailing comma is sometimes present and other times absent, often mixing with/without trailing comma styles in a single file, and sometimes in consecutive enum declarations. Clearly, omitting the comma is the more portable style, and this patch changes all enum declarations to use the portable omitted dangling comma style consistently. Signed-off-by: Gary V.

* | grep: support NUL chars in search strings for -FRené Scharfe2010-05-24
|/ | | | | | | | | | | Search patterns in a file specified with -f can contain NUL characters. The current code ignores all characters on a line after a NUL. Pass the actual length of the line all the way from the pattern file to fixmatch() and use it for case-sensitive fixed string matching.

The default for all three is no color, but they can be configured using color.grep.<slot>. The first two are similar to the corresponding options in GNU grep, except that GNU grep applies the color to the entire line, not just non-matching text.

| * grep: Colorize filename, line number, and separatorMark Lodato2010-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Colorize the filename, line number, and separator in git grep output, as GNU grep does. The colors are customizable through color.grep.<slot>. The default is to only color the separator (in cyan), since this gives the biggest legibility increase without overwhelming the user with colors. GNU grep also defaults cyan for the separator, but defaults to magenta for the filename and to green for the line number, as well. There is one difference from GNU grep: When a binary file matches without -a, GNU grep does not color the <file> in "Binary file <file> matches", but we do. Like GNU grep, if --null is given, the null separators are not colored. For config.txt, use a a sub-list to describe the slots, rather than a single paragraph with parentheses, since this is much more readable. Remove the cast to int for `rm_eo - rm_so` since it is not necessary. Signed-off-by: Mark Lodato <lodatom@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

However, the user almost always want to find commits "done by this person on that topic". With "--all-match" option, a series of grep patterns can be turned into a requirement that all of them must produce a match, but that makes it impossible to ask for "done by me, on either this or that" with: log --author=me --committer=him --grep=this --grep=that because it will require both "this" and "that" to appear. Change the "header" parser of grep library to treat the headers specially, and parse it as: (all-match-OR (HEADER-AUTHOR me) (HEADER-COMMITTER him) (OR (PATTERN this) (PATTERN that) ) ) Even though the "log" command line parser doesn't give direct access to the extended grep syntax to group terms with parentheses, this change will cover the majority of the case the users would want. This incidentally revealed that one test in t7002 was bogus. It ran: log --author=Thor --grep=Thu --format='%s' and expected (wrongly) "Thu" to match "Thursday" in the author/committer date, but that would never match, as the timestamp in raw commit buffer does not have the name of the day-of-the-week.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is useful to grep directories non-recursively, e.g. when one wants to look for all files in the toplevel directory, but not in any subdirectory, or in Documentation/, but not in Documentation/technical/. This patch adds support for --max-depth <depth> option to git-grep. If it is given, git-grep descends at most <depth> levels of directories below paths specified on the command line. Note that if path specified on command line contains wildcards, this option makes no sense, e.g. $ git grep -l --max-depth 0 GNU -- 'contrib/*' (note the quotes) will search all files in contrib/, even in subdirectories, because '*' matches all files. Documentation updates, bash-completion and simple test cases are also provided. Signed-off-by: Michał Kiedrowicz <michal.kiedrowicz@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | The new option -p instructs git grep to print the previous function definition as a context line, similar to diff -p. Such context lines are marked with an equal sign instead of a dash. This option complements the existing context options -A, -B, -C. Function definitions are detected using the same heuristic that diff uses. User defined regular expressions are not supported, yet.
