René Scharfe	b482759983	grep: unset GREP_OPTIONS before spawning external grep While we're at it, also unset GREP_COLOR and GREP_COLORS in case colouring is not enabled, to be on the safe side. The presence of these variables alone is not sufficient to trigger coloured output with GNU grep, but other implementations may behave differently.

Brian Collins	5183bf6727	grep: Allow case insensitive search of fixed-strings "git grep" currently an error when you combine the -F and -i flags. This isn't in line with how GNU grep handles it. This patch allows the simultaneous use of those flags.

Matt Kraai	cfe370c647	grep: do not segfault when -f is used "git grep" would segfault if its -f option was used because it would try to use an uninitialized strbuf, so initialize the strbuf.

Clemens Buchacher	493b7a08d8	grep: accept relative paths outside current working directory "git grep" would barf at relative paths pointing outside the current working directory (or subdirectories thereof). Use quote_path_relative(), which can handle such cases just fine. [jc: added tests.] Signed-off-by: Clemens Buchacher <drizzd@aon.at> Signed-off-by: Junio C Hamano <gitster@pobox.com>	16 years ago
Michał Kiedrowicz	a91f453f64	grep: Add --max-depth option. 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.

René Scharfe	60ecac98ed	grep -p: support user defined regular expressions Respect the userdiff attributes and config settings when looking for lines with function definitions in git grep -p.

René Scharfe	2944e4e614	grep: add option -p/--show-function 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.

René Scharfe	046802d015	grep: print context hunk marks between files Print a hunk mark before matches from a new file are shown, in addition to the current behaviour of printing them if lines have been skipped. The result is easier to read, as (presumably unrelated) matches from different files are separated by a hunk mark. GNU grep does the same.

René Scharfe	dbb6a4ada6	grep: fix word-regexp at the beginning of lines After bol is forwarded, it doesn't represent the beginning of the line any more. This means that the beginning-of-line marker (^) mustn't match, i.e. the regex flag REG_NOTBOL needs to be set. This bug was introduced by `fb62eb7fab` ("grep -w: forward to next possible position after rejected match").

Nguyễn Thái Ngọc Duy	57d43466fb	grep: grep cache entries if they are "assume unchanged" "Assume unchanged" bit means "please pretend that I have never touched this file", so if user removes the file, we should not care. This patch teaches "git grep" to use cache version in such situations. External grep case has not been fixed yet. But given that on the platform that CE_VALID bit may be used like Windows, external grep is not available anyway, I would wait for people to raise their hands before touching it.

Jeff King	87539416fd	tests: grep portability fixes We try to avoid using the "-q" or "-e" options, as they are largely useless, as explained in `aadbe44f`. There is one exception for "-e" here, which is in t7701 used to produce an "or" of patterns. This can be rewritten as an egrep pattern. This patch also removes use of "grep -F" in favor of the more widely available "fgrep".

Junio C Hamano	a4d7d2c6db	log --author/--committer: really match only with name part When we tried to find commits done by AUTHOR, the first implementation tried to pattern match a line with "^author .AUTHOR", which later was enhanced to strip leading caret and look for "^author AUTHOR" when the search pattern was anchored at the left end (i.e. --author="^AUTHOR"). This had a few problems: When looking for fixed strings (e.g. "git log -F --author=x --grep=y"), the regexp internally used "^author .x" would never match anything; To match at the end (e.g. "git log --author='google.com>$'"), the generated regexp has to also match the trailing timestamp part the commit header lines have. Also, in order to determine if the '$' at the end means "match at the end of the line" or just a literal dollar sign (probably backslash-quoted), we would need to parse the regexp ourselves. An earlier alternative tried to make sure that a line matches "^author " (to limit by field name) and the user supplied pattern at the same time. While it solved the -F problem by introducing a special override for matching the "^author ", it did not solve the trailing timestamp nor tail match problem. It also would have matched every commit if --author=author was asked for, not because the author's email part had this string, but because every commit header line that talks about the author begins with that field name, regardleses of who wrote it. Instead of piling more hacks on top of hacks, this rethinks the grep machinery that is used to look for strings in the commit header, and makes sure that (1) field name matches literally at the beginning of the line, followed by a SP, and (2) the user supplied pattern is matched against the remainder of the line, excluding the trailing timestamp data.

Junio C Hamano	41ac414ea2	Sane use of test_expect_failure Originally, test_expect_failure was designed to be the opposite of test_expect_success, but this was a bad decision. Most tests run a series of commands that leads to the single command that needs to be tested, like this: test_expect_{success,failure} 'test title' ' setup1 && setup2 && setup3 && what is to be tested ' And expecting a failure exit from the whole sequence misses the point of writing tests. Your setup$N that are supposed to succeed may have failed without even reaching what you are trying to test. The only valid use of test_expect_failure is to check a trivial single command that is expected to fail, which is a minority in tests of Porcelain-ish commands. This large-ish patch rewrites all uses of test_expect_failure to use test_expect_success and rewrites the condition of what is tested, like this: test_expect_success 'test title' ' setup1 && setup2 && setup3 && ! this command should fail ' test_expect_failure is redefined to serve as a reminder that that test should succeed but due to a known breakage in git it currently does not pass. So if git-foo command should create a file 'bar' but you discovered a bug that it doesn't, you can write a test like this: test_expect_failure 'git-foo should create bar' ' rm -f bar && git foo && test -f bar ' This construct acts similar to test_expect_success, but instead of reporting "ok/FAIL" like test_expect_success does, the outcome is reported as "FIXED/still broken".

Junio C Hamano	d99ebf0817	Split grep arguments in a way that does not requires to add /dev/null. In order to (almost) always show the name of the file without relying on "-H" option of GNU grep, we used to add /dev/null to the argument list unless we are doing -l or -L. This caused "/dev/null:0" to show up when -c is given in the output. It is not enough to add -c to the set of options we do not pass /dev/null for. When we have too many files, we invoke grep multiple times and we need to avoid giving a widow filename to the last invocation -- otherwise we will not see the name. This keeps two filenames when the argv[] buffer is about to overflow and we have not finished iterating over the index, so that the last round will always have at least two paths to work with (and not require /dev/null). An obvious and the only exception is when there is only 1 file that is given to the underlying grep, and in that case we avoid passing /dev/null and let the external "grep -c" report only the number of matches.

Junio C Hamano	0d042fecf2	git-grep: show pathnames relative to the current directory By default, the command shows pathnames relative to the current directory. Use --full-name (the same flag to do so in ls-files) if you want to see the full pathname relative to the project root. This makes it very pleasant to run in Emacs compilation (or "grep-find") buffer. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
Junio C Hamano	f25b79397c	Fix "grep -w" We used to find the first match of the pattern and then if the match is not for the entire word, declared that the whole line does not match. But that is wrong. The command "git grep -w -e mmap" should find that a line "foo_mmap bar mmap baz" matches, by tring the second instance of pattern "mmap" on the same line. Problems an earlier round of "fix" had were pointed out by Morten Welinder, which have been incorporated in the t7002 tests. Signed-off-by: Junio C Hamano <junkio@cox.net>	19 years ago
