2015-12-08Merge branch 'ad/sha1-update-chunked' into maintLibravatar Junio C Hamano1-0/+13
Apple's common crypto implementation of SHA1_Update() does not take more than 4GB at a time, and we now have a compile-time workaround for it. * ad/sha1-update-chunked: sha1: allow limiting the size of the data passed to SHA1_Update() sha1: provide another level of indirection for the SHA-1 functions

2015-11-05sha1: allow limiting the size of the data passed to SHA1_Update()Libravatar Atousa Pahlevan Duprat1-0/+13
Using the previous commit's inredirection mechanism for SHA1, support a chunked implementation of SHA1_Update() that limits the amount of data in the chunk passed to SHA1_Update(). This is enabled by using the Makefile variable SHA1_MAX_BLOCK_SIZE to specify chunk size. When using Apple's CommonCrypto library this is set to 1GiB (the implementation cannot handle more 4GiB).

2015-10-21Makefile: make curl-config path configurableLibravatar Remi Pommarel1-2/+6
There are situations, e.g. during cross compilation, where curl-config program is not present in the PATH. Make the makefile use a configurable curl-config program passed through CURL_CONFIG variable which can be set through config.mak. Also make this variable tunable through use of autoconf/configure. Configure will set CURL_CONFIG variable in config.mak.autogen to whatever value has been passed to ac_cv_prog_CURL_CONFIG.

2015-10-21Makefile: link libcurl before zlibLibravatar Remi Pommarel1-4/+5
For static linking especially library order while linking is important. For example, libcurl wants symbols from zlib when building http-push, http-fetch and remote-curl. So for these programs libcurl has to be linked before zlib.

2015-08-25generate-cmdlist: re-implement as shell scriptLibravatar Eric Sunshine1-2/+2
527ec39 (generate-cmdlist: parse common group commands, 2015-05-21) replaced generate-cmdlist.sh with a more functional Perl version, generate-cmdlist.perl. The Perl version gleans named tags from a new "common groups" section in command-list.txt and recognizes those tags in "command list" section entries in place of the old 'common' tag. This allows git-help to, not only recognize, but also group common commands. Although the tests require Perl, 527ec39 creates an unconditional dependence upon Perl in the build system itself, which can not be overridden with NO_PERL. Such a dependency may be undesirable; for instance, the 'git-lite' package in the FreeBSD ports tree is intended as a minimal Git installation (which may, for example, be useful on servers needing only local clone and update capability), which, historically, has not depended upon Perl[1]. Therefore, revive generate-cmdlist.sh and extend it to recognize "common groups" and its named tags. Retire generate-cmdlist.perl.

2015-08-19submodule: implement a config API for lookup of .gitmodules valuesLibravatar Heiko Voigt1-0/+2
In a superproject some commands need to interact with submodules. They need to query values from the .gitmodules file either from the worktree of from certain revisions. At the moment this is quite hard since a caller would need to read the .gitmodules file from the history and then parse the values. We want to provide an API for this so we have one place to get values from .gitmodules from any revision (including the worktree). The API is realized as a cache which allows us to lazily read .gitmodules configurations by commit into a runtime cache which can then be used to easily lookup values from it. Currently only the values for path or name are stored but it can be extended for any value needed. It is expected that .gitmodules files do not change often between commits. Thats why we lookup the .gitmodules sha1 from a commit and then either lookup an already parsed configuration or parse and cache an unknown one for each sha1. The cache is lazily build on demand for each requested commit. This cache can be used for all purposes which need knowledge about submodule configurations. Example use cases are: * Recursive submodule checkout needs to lookup a submodule name from its path when a submodule first appears. This needs be done before this configuration exists in the worktree. * The implementation of submodule support for 'git archive' needs to lookup the submodule name to generate the archive when given a revision that is not checked out. * 'git fetch' when given the --recurse-submodules=on-demand option (or configuration) needs to lookup submodule names by path from the database rather than reading from the worktree. For new submodule it needs to lookup the name from its path to allow cloning new submodules into the .git folder so they can be checked out without any network interaction when the user does a checkout of that revision.

2015-08-04builtin-am: implement skeletal builtin amLibravatar Paul Tan1-0/+1
For the purpose of rewriting git-am.sh into a C builtin, implement a skeletal builtin/am.c that redirects to $GIT_EXEC_PATH/git-am if the environment variable _GIT_USE_BUILTIN_AM is not defined. Since in the Makefile git-am.sh takes precedence over builtin/am.c, $GIT_EXEC_PATH/git-am will contain the shell script git-am.sh, and thus this allows us to fall back on the functional git-am.sh when running the test suite for tests that depend on a working git-am implementation. Since git-am.sh cannot handle any environment modifications by setup_git_directory(), "am" is declared with no setup flags in git.c. On the other hand, to re-implement git-am.sh in builtin/am.c, we need to run all the git dir and work tree setup logic that git.c typically does for us. As such, we work around this temporarily by copying the logic in git.c's run_builtin(), which is roughly: prefix = setup_git_directory(); trace_repo_setup(prefix); setup_work_tree(); This redirection should be removed when all the features of git-am.sh have been re-implemented in builtin/am.c.

2015-05-29Makefile: silence perl/PM.stamp recipeLibravatar Jeff King1-1/+1
Every time we run "make", we update perl/PM.stamp, which contains a list of all of the perl module files (if it's updated, we need to rebuild perl/perl.mak, since the Makefile will not otherwise know about the new files). This means that every time "make" is run, we see: GEN perl/PM.stamp in the output, even though it is not likely to have changed. Let's make this recipe completely silent, as we do for other auto-generated dependency files (e.g., GIT-CFLAGS).

However, we actually update the file's timestamp each time the recipe is run, whether anything changed or not. As a result, any files which depend on it (for example, all of the perl scripts, which need to know whether NO_PERL was set) will be re-built every time. Let's do our usual trick of writing to a tempfile, then doing a "cmp || mv" to update the file only when something changed.

2015-04-16strbuf_getwholeline: use getdelim if it is availableLibravatar Jeff King1-0/+6
We spend a lot of time in strbuf_getwholeline in a tight loop reading characters from a stdio handle into a buffer. The libc getdelim() function can do this for us with less overhead. It's in POSIX.1-2008, and was a GNU extension before that. Therefore we can't rely on it, but can fall back to the existing getc loop when it is not available. The HAVE_GETDELIM knob is turned on automatically for Linux, where we have glibc. We don't need to set any new feature-test macros, because we already define _GNU_SOURCE. Other systems that implement getdelim may need to other macros (probably _POSIX_C_SOURCE >= 200809L), but we can address that along with setting the Makefile knob after testing the feature on those systems. Running "git rev-parse refs/heads/does-not-exist" on a repo with an extremely large (1.6GB) packed-refs file went from (best-of-5): real 0m8.601s user 0m8.084s sys 0m0.524s to: real 0m6.768s user 0m6.340s sys 0m0.432s for a wall-clock speedup of 21%.

2015-01-12gettext.h: add parentheses around N_ expansion if supportedLibravatar Kyle J. McKay1-0/+17
The gettext N_ macro is used to mark strings for translation without actually translating them. At runtime the string is expected to be passed to the gettext API for translation. If two N_ macro invocations appear next to each other with only whitespace (or nothing at all) between them, the two separate strings will be marked for translation, but the preprocessor will then silently combine the strings into one and at runtime the string passed to gettext will not match the strings that were translated so no translation will actually occur. Avoid this by adding parentheses around the expansion of the N_ macro so that instead of ending up with two adjacent strings that are then combined by the preprocessor, two adjacent strings surrounded by parentheses result instead which causes a compile error so the mistake can be quickly found and corrected. However, since these string literals are typically assigned to static variables and not all compilers support parenthesized string literal assignments, allow this to be controlled by the Makefile with the default only enabled when the compiler is known to support the syntax. For now only __GNUC__ enables this by default which covers both gcc and clang which should result in early detection of any adjacent N_ macros. Although the necessary tests make the affected files a bit less elegant, the benefit of avoiding propagation of a translation- marking error to all the translation teams thus creating extra work for them when the error is eventually detected and fixed would seem to outweigh the minor inelegance the additional configuration tests introduce.
