2014-07-13git: add performance tracing for git's main() function to debug scriptsLibravatar Karsten Blees1-0/+2
Use trace_performance to measure and print execution time and command line arguments of the entire main() function. In constrast to the shell's 'time' utility, which measures total time of the parent process, this logs all involved git commands recursively. This is particularly useful to debug performance issues of scripted commands (i.e. which git commands were called with which parameters, and how long did they execute). Due to git's deliberate use of exit(), the implementation uses an atexit routine rather than just adding trace_performance_since() at the end of main(). Usage example: > GIT_TRACE_PERFORMANCE=~/git-trace.log git stash list Creates a log file like this: 23:57:38.638765 trace.c:405 performance: 0.000310107 s: git command: 'git' 'rev-parse' '--git-dir' 23:57:38.644387 trace.c:405 performance: 0.000261759 s: git command: 'git' 'rev-parse' '--show-toplevel' 23:57:38.646207 trace.c:405 performance: 0.000304468 s: git command: 'git' 'config' '--get-colorbool' 'color.interactive' 23:57:38.648491 trace.c:405 performance: 0.000241667 s: git command: 'git' 'config' '--get-color' 'color.interactive.help' 'red bold' 23:57:38.650465 trace.c:405 performance: 0.000243063 s: git command: 'git' 'config' '--get-color' '' 'reset' 23:57:38.654850 trace.c:405 performance: 0.025126313 s: git command: 'git' 'stash' 'list' Signed-off-by: Karsten Blees <blees@dcon.de> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2014-06-23verify-commit: scriptable commit signature verificationLibravatar Michael J Gruber1-0/+1
Commit signatures can be verified using "git show -s --show-signature" or the "%G?" pretty format and parsing the output, which is well suited for user inspection, but not for scripting. Provide a command "verify-commit" which is analogous to "verify-tag": It returns 0 for good signatures and non-zero otherwise, has the gpg output on stderr and (optionally) the commit object on stdout, sans the signature, just like "verify-tag" does.

2014-06-20git: avoid magic number with skip_prefixLibravatar Jeff King1-2/+2
After handling options, any leftover arguments should be commands. However, we pass through "--help" and "--version", so that we convert them into "git help" and "git version" respectively. This is a straightforward use of skip_prefix to avoid a magic number, but while we are there, it is worth adding a comment to explain this otherwise confusing behavior.

2014-06-20use skip_prefix to avoid magic numbersLibravatar Jeff King1-10/+8
It's a common idiom to match a prefix and then skip past it with a magic number, like: if (starts_with(foo, "bar")) foo += 3; This is easy to get wrong, since you have to count the prefix string yourself, and there's no compiler check if the string changes. We can use skip_prefix to avoid the magic numbers here. Note that some of these conversions could be much shorter. For example: if (starts_with(arg, "--foo=")) { bar = arg + 6; continue; } could become: if (skip_prefix(arg, "--foo=", &bar)) continue; However, I have left it as: if (skip_prefix(arg, "--foo=", &v)) { bar = v; continue; } to visually match nearby cases which need to actually process the string. Like: if (skip_prefix(arg, "--foo=", &v)) { bar = atoi(v); continue; } Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2014-06-10git potty: restore environments after alias expansionLibravatar Nguyễn Thái Ngọc Duy1-4/+49
Commit 4ad8332 (t0001: test git init when run via an alias - 2010-11-26) noted breakages when running init via alias. The problem is for alias to be used, $GIT_DIR must be searched, but 'init' and 'clone' are not happy with that. So we start a new process like an external command, with clean environment in this case. Env variables that are set by command line (e.g. "git --git-dir=.. ") are kept. This should also fix autocorrecting a command typo to "init" because it's the same problem: aliases are read, then "init" is unhappy with $GIT_DIR already set up because of that.

The motivation of this patch is to get closer to a goal of being able to have a core subset of git functionality built in to git.

This patch is meant to be mostly a literal translation of the git-repack script; the intent is that later patches would start using more library facilities, but this patch is meant to be as close to a no-op as possible so it doesn't do that kind of thing.

2013-09-09git: run in a directory given with -C optionLibravatar Nazri Ramliy1-1/+12
This is similar in spirit to "make -C dir ..." and "tar -C dir ...". It takes more keypresses to invoke git command in a different directory without leaving the current directory: 1. (cd ~/foo && git status) git --git-dir=~/foo/.git --work-dir=~/foo status GIT_DIR=~/foo/.git GIT_WORK_TREE=~/foo git status 2. (cd ../..; git grep foo) 3. for d in d1 d2 d3; do (cd $d && git svn rebase); done The methods shown above are acceptable for scripting but are too cumbersome for quick command line invocations. With this new option, the above can be done with fewer keystrokes: 1. git -C ~/foo status 2. git -C ../.. grep foo 3. for d in d1 d2 d3; do git -C $d svn rebase; done A new test script is added to verify the behavior of this option with other path-related options like --git-dir and --work-tree.

Not having an open FD in the 0--2 range can lead to strange results, for example, a subsequent open() may return 2 (stderr) and then a die() would clobber this file. git-daemon and git-shell already guarded against this, but apparently users also manage to trip over it in other git commands.

2013-07-15pathspec: support :(glob) syntaxLibravatar Nguyễn Thái Ngọc Duy1-0/+8
:(glob)path differs from plain pathspec that it uses wildmatch with WM_PATHNAME while the other uses fnmatch without FNM_PATHNAME. The difference lies in how '*' (and '**') is processed. With the introduction of :(glob) and :(literal) and their global options --[no]glob-pathspecs, the user can: - make everything literal by default via --noglob-pathspecs --literal-pathspecs cannot be used for this purpose as it disables _all_ pathspec magic. - individually turn on globbing with :(glob) - make everything globbing by default via --glob-pathspecs - individually turn off globbing with :(literal) The implication behind this is, there is no way to gain the default matching behavior (i.e. fnmatch without FNM_PATHNAME). You either get new globbing or literal. The old fnmatch behavior is considered deprecated and discouraged to use.

2013-04-28sparse: Fix mingw_main() argument number/type errorsLibravatar Ramsay Jones1-1/+2
Sparse issues 68 errors (two errors for each main() function) such as the following: SP git.c git.c:510:5: error: too many arguments for function mingw_main git.c:510:5: error: symbol 'mingw_main' redeclared with different type \ (originally declared at git.c:510) - different argument counts The errors are caused by the 'main' macro used by the MinGW build to provide a replacement main() function. The original main function is effectively renamed to 'mingw_main' and is called from the new main function. The replacement main is used to execute certain actions common to all git programs on MinGW (e.g. ensure the standard I/O streams are in binary mode). In order to suppress the errors, we change the macro to include the parameters in the declaration of the mingw_main function. Unfortunately, this change provokes both sparse and gcc to complain about 9 calls to mingw_main(), such as the following: CC git.o git.c: In function 'main': git.c:510: warning: passing argument 2 of 'mingw_main' from \ incompatible pointer type git.c:510: note: expected 'const char **' but argument is of \ type 'char **' In order to suppress these warnings, since both of the main functions need to be declared with the same prototype, we change the declaration of the 9 main functions, thus: int main(int argc, char **argv) Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2013-03-08setup: suppress implicit "." work-tree for bare reposLibravatar Jeff King1-0/+1
If an explicit GIT_DIR is given without a working tree, we implicitly assume that the current working directory should be used as the working tree. E.g.,: GIT_DIR=/some/repo.git git status would compare against the cwd. Unfortunately, we fool this rule for sub-invocations of git by setting GIT_DIR internally ourselves. For example: git init foo cd foo/.git git status ;# fails, as we expect git config alias.st status git status ;# does not fail, but should What happens is that we run setup_git_directory when doing alias lookup (since we need to see the config), set GIT_DIR as a result, and then leave GIT_WORK_TREE blank (because we do not have one). Then when we actually run the status command, we do setup_git_directory again, which sees our explicit GIT_DIR and uses the cwd as an implicit worktree. It's tempting to argue that we should be suppressing that second invocation of setup_git_directory, as it could use the values we already found in memory. However, the problem still exists for sub-processes (e.g., if "git status" were an external command). You can see another example with the "--bare" option, which sets GIT_DIR explicitly. For example: git init foo cd foo/.git git status ;# fails git --bare status ;# does NOT fail We need some way of telling sub-processes "even though GIT_DIR is set, do not use cwd as an implicit working tree". We could do it by putting a special token into GIT_WORK_TREE, but the obvious choice (an empty string) has some portability problems. Instead, we add a new boolean variable, GIT_IMPLICIT_WORK_TREE, which suppresses the use of cwd as a working tree when GIT_DIR is set. We trigger the new variable when we know we are in a bare setting. The variable is left intentionally undocumented, as this is an internal detail (for now, anyway). If somebody comes up with a good alternate use for it, and once we are confident we have shaken any bugs out of it, we can consider promoting it further.

This works in a similar manner to git-check-attr. Thanks to Jeff King and Junio C Hamano for the idea: http://thread.gmane.org/gmane.comp.version-control.git/108671/focus=108815 Signed-off-by: Adam Spiers <git@adamspiers.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-12-19add global --literal-pathspecs optionLibravatar Jeff King1-0/+8
Git takes pathspec arguments in many places to limit the scope of an operation. These pathspecs are treated not as literal paths, but as glob patterns that can be fed to fnmatch. When a user is giving a specific pattern, this is a nice feature. However, when programatically providing pathspecs, it can be a nuisance. For example, to find the latest revision which modified "$foo", one can use "git rev-list -- $foo". But if "$foo" contains glob characters (e.g., "f*"), it will erroneously match more entries than desired. The caller needs to quote the characters in $foo, and even then, the results may not be exactly the same as with a literal pathspec. For instance, the depth checks in match_pathspec_depth do not kick in if we match via fnmatch. This patch introduces a global command-line option (i.e., one for "git" itself, not for specific commands) to turn this behavior off. It also has a matching environment variable, which can make it easier if you are a script or porcelain interface that is going to issue many such commands. This option cannot turn off globbing for particular pathspecs. That could eventually be done with a ":(noglob)" magic pathspec prefix. However, that level of granularity is more cumbersome to use for many cases, and doing ":(noglob)" right would mean converting the whole codebase to use "struct pathspec", as the usual "const char **pathspec" cannot represent extra per-item flags.

2012-10-29Move setup_diff_pager to libgit.aLibravatar Nguyễn Thái Ngọc Duy1-33/+0
This is used by diff-no-index.c, part of libgit.a while it stays in builtin/diff.c. Move it to diff.c so that we won't get undefined reference if a program that uses libgit.a happens to pull it in. While at it, move check_pager from git.c to pager.c. It makes more sense there and pager.c is also part of libgit.a Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Jeff King <peff@peff.net>
2012-06-25add 'git credential' plumbing commandLibravatar Javier Roucher Iglesias1-0/+1
The credential API is in C, and not available to scripting languages. Expose the functionalities of the API by wrapping them into a new plumbing command "git credentials". In other words, replace the internal "test-credential" by an official Git command.

2012-06-03move git_version_string into version.cLibravatar Jeff King1-2/+0
The global git_version_string currently lives in git.c, but doesn't have anything to do with the git wrapper. Let's move it into its own file, where it will be more appropriate to build more version-related functions. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
