2014-06-03Merge branch 'ks/tree-diff-nway'Libravatar Junio C Hamano1-0/+8
Instead of running N pair-wise diff-trees when inspecting a N-parent merge, find the set of paths that were touched by walking N+1 trees in parallel. These set of paths can then be turned into N pair-wise diff-tree results to be processed through rename detections and such. And N=2 case nicely degenerates to the usual 2-way diff-tree, which is very nice. * ks/tree-diff-nway: mingw: activate alloca combine-diff: speed it up, by using multiparent diff tree-walker directly tree-diff: rework diff_tree() to generate diffs for multiparent cases as well Portable alloca for Git tree-diff: reuse base str(buf) memory on sub-tree recursion tree-diff: no need to call "full" diff_tree_sha1 from show_path() tree-diff: rework diff_tree interface to be sha1 based tree-diff: diff_tree() should now be static tree-diff: remove special-case diff-emitting code for empty-tree cases tree-diff: simplify tree_entry_pathcmp tree-diff: show_path prototype is not needed anymore tree-diff: rename compare_tree_entry -> tree_entry_pathcmp tree-diff: move all action-taking code out of compare_tree_entry() tree-diff: don't assume compare_tree_entry() returns -1,0,1 tree-diff: consolidate code for emitting diffs and recursion in one place tree-diff: show_tree() is not needed tree-diff: no need to pass match to skip_uninteresting() tree-diff: no need to manually verify that there is no mode change for a path combine-diff: move changed-paths scanning logic into its own function combine-diff: move show_log_first logic/action out of paths scanning
2014-03-27Portable alloca for GitLibravatar Kirill Smelkov1-0/+8
In the next patch we'll have to use alloca() for performance reasons, but since alloca is non-standardized and is not portable, let's have a trick with compatibility wrappers: 1. at configure time, determine, do we have working alloca() through alloca.h, and define #define HAVE_ALLOCA_H if yes. 2. in code #ifdef HAVE_ALLOCA_H # include <alloca.h> # define xalloca(size) (alloca(size)) # define xalloca_free(p) do {} while(0) #else # define xalloca(size) (xmalloc(size)) # define xalloca_free(p) (free(p)) #endif and use it like func() { p = xalloca(size); ... xalloca_free(p); } This way, for systems, where alloca is available, we'll have optimal on-stack allocations with fast executions. On the other hand, on systems, where alloca is not available, this gracefully fallbacks to xmalloc/free. Both autoconf and config.mak.uname configurations were updated. For autoconf, we are not bothering considering cases, when no alloca.h is available, but alloca() works some other way - its simply alloca.h is available and works or not, everything else is deep legacy. For config.mak.uname, I've tried to make my almost-sure guess for where alloca() is available, but since I only have access to Linux it is the only change I can be sure about myself, with relevant to other changed systems people Cc'ed. NOTE SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations. I've changed that to now-common HAVE_ALLOCA_H=YesPlease which should be correct.

2014-03-11configure.ac: link with -liconv for locale_charset()Libravatar Dmitry Marakasov1-1/+1
On e.g. FreeBSD 10.x, the following situation is common: - there's iconv implementation in libc, which has no locale_charset() function - there's GNU libiconv installed from Ports Collection Git build process - detects that iconv is in libc and thus -liconv is not needed for it - detects locale_charset in -liconv, but for some reason doesn't add it to CHARSET_LIB (as it would do with -lcharset if locale_charset() was found there instead of -liconv) - git doesn't build due to unresolved external locale_charset() Fix this by adding -liconv to CHARSET_LIB if locale_charset() is detected in this library.

2012-12-19git-compat-util.h: do not #include <sys/param.h> by defaultLibravatar Junio C Hamano1-6/+0
Earlier we allowed platforms that lack <sys/param.h> not to include the header file from git-compat-util.h; we have included this header file since the early days back when we used MAXPATHLEN (which we no longer use) and also depended on it slurping ULONG_MAX (which we get by including stdint.h or inttypes.h these days). It turns out that we can compile our modern codebase just file without including it on many platforms (so far, Fedora, Debian, Ubuntu, MinGW, Mac OS X, Cygwin, HP-Nonstop, QNX and z/OS are reported to be OK). Let's stop including it by default, and on platforms that need it to be included, leave "make NEEDS_SYS_PARAM_H=YesPlease" as an escape hatch and ask them to report to us, so that we can find out about the real dependency and fix it in a more platform agnostic way.

2012-11-27configure.ac: fix pthreads detection on Mac OS XLibravatar Max Horn1-1/+11
The configure script checks whether certain flags are required to use pthreads. But it did not consider that *none* might be needed (as is the case on Mac OS X). This lead to configure adding "-mt" to the list of flags (which does nothing on OS X except producing a warning). This in turn triggered a compiler warning on every single file. To solve this, we now first check if pthreads work without extra flags. This means the check is now order dependant, hence a comment is added explaining this, and the reasons for it. Note that it might be possible to write an order independent test, but it does not seem worth the extra effort required for implementing and testing such a solution, when this simple solution exists and works.

Thanks to our 'GIT_CONF_SUBST' layer in configure.ac, a make variable 'VAR' can be defined to a value 'VAL' at ./configure runtime in our build system simply by using "GIT_CONF_SUBST([VAR], [VAL])" in configure.ac, rather than having both to call "AC_SUBST([VAR], [VAL])" in configure.ac and adding the 'VAR = @VAR@' definition in config.mak.in.

2012-05-30docs: drop asciidoc7compatible flagLibravatar Jeff King1-7/+0
When we made the switch to supporting asciidoc 8 in 4c7100a (Documentation: adjust to AsciiDoc 8, 2007-06-14), we were able to leave most of the documentation intact by defining asciidoc7compatible. Since commit 6cf378f (docs: stop using asciidoc no-inline-literal, 2012-04-26), we don't support versions of asciidoc older than 8.4.1, which is when inline literals were introduced. Therefore there is not much point in keeping our documentation compatible with asciidoc 7. So we are now free to drop the asciidoc7compatible flag and update the documentation itself to assume asciidoc8. Fortunately, doing the latter is very easy; we weren't using any of the constructs impacted by asciidoc7compatible, so there are no changes to make. The reason is somewhat subtle. The asciidoc7compatible affects only super/sub-scripts ("^" and "~") and index terms. We don't use the latter at all. Nor we do we use the former, but we did have to protect them from accidental expansion in constructs like "rev^1". However, all of our uses of "~" and "^" are either in code blocks (which are rendered literally), or inside backticks. Prior to 6cf378f, backticks were not inline literals, and needed proper quoting. But post-6cf378f, we don't have to worry whether we are using the old or new rules, as those characters are not interpreted at all in either case. I verified that the result of "make install-html install-man" is identical before and after this patch on asciidoc 8.6.7.

2012-03-26configure: be more idiomaticLibravatar Stefano Lattarini1-89/+87
Lots of code in Git's configure.ac doesn't follow the typical formatting, idioms and best practices for Autoconf input files. Improve the situation. There are probably many more similar improvements to be done, but trying to clump all of them in a single change would make it unreviewable, so we content ourselves with a partial improvement. This change is just cosmetic, and should cause no semantic change. The most relevant of the changes introduced by this patch are: - Do not add trailing '\' characters for line continuation where they are not truly needed. - In several (but not all) macro calls, properly quote the arguments. - Few cosmetic changes in spacing and comments.

2012-03-09configure: allow user to prevent $PATH "sanitization" on SolarisLibravatar Stefano Lattarini1-0/+17
On a Solaris 10 system with Solaris make installed as '/usr/xpg4/bin/make', GNU make installed as '/usr/local/bin/make', and with '/usr/local/bin' appearing in $PATH *before* '/usr/xpg4/bin', I was seeing errors like this upon invoking "make all": Usage : make [ -f makefile ][ -K statefile ]... make: Fatal error: Unknown option `-C' This happenes because the Git's Makefile, when running on Solaris, automatically "sanitizes" $PATH by prepending '/usr/xpg6/bin' and '/usr/xpg4/bin' to it in order to avoid using non-POSIX /bin/sh from being used. In the setup described above, however, this has an unintended consequence of forcing the use of Solaris make in recursive make invocations -- even if the $(MAKE) macro is being correctly used in them! When building without using the autoconf machinery, this can be solved by overriding $(SANE_TOOL_PATH). Teach the autoconf machinery to also allow users of ./configure to override it from the command line with a new --with-sane-tool-path option.

2011-12-05i18n: add infrastructure for translating Git with gettextLibravatar Ævar Arnfjörð Bjarmason1-0/+19
Change the skeleton implementation of i18n in Git to one that can show localized strings to users for our C, Shell and Perl programs using either GNU libintl or the Solaris gettext implementation. This new internationalization support is enabled by default. If gettext isn't available, or if Git is compiled with NO_GETTEXT=YesPlease, Git falls back on its current behavior of showing interface messages in English. When using the autoconf script we'll auto-detect if the gettext libraries are installed and act appropriately. This change is somewhat large because as well as adding a C, Shell and Perl i18n interface we're adding a lot of tests for them, and for those tests to work we need a skeleton PO file to actually test translations. A minimal Icelandic translation is included for this purpose. Icelandic includes multi-byte characters which makes it easy to test various edge cases, and it's a language I happen to understand. The rest of the commit message goes into detail about various sub-parts of this commit. = Installation Gettext .mo files will be installed and looked for in the standard $(prefix)/share/locale path. GIT_TEXTDOMAINDIR can also be set to override that, but that's only intended to be used to test Git itself. = Perl Perl code that's to be localized should use the new Git::I18n module. It imports a __ function into the caller's package by default. Instead of using the high level Locale::TextDomain interface I've opted to use the low-level (equivalent to the C interface) Locale::Messages module, which Locale::TextDomain itself uses. Locale::TextDomain does a lot of redundant work we don't need, and some of it would potentially introduce bugs. It tries to set the $TEXTDOMAIN based on package of the caller, and has its own hardcoded paths where it'll search for messages. I found it easier just to completely avoid it rather than try to circumvent its behavior. In any case, this is an issue wholly internal Git::I18N. Its guts can be changed later if that's deemed necessary. See <AANLkTilYD_NyIZMyj9dHtVk-ylVBfvyxpCC7982LWnVd@mail.gmail.com> for a further elaboration on this topic. = Shell Shell code that's to be localized should use the git-sh-i18n library. It's basically just a wrapper for the system's gettext.sh. If gettext.sh isn't available we'll fall back on gettext(1) if it's available. The latter is available without the former on Solaris, which has its own non-GNU gettext implementation. We also need to emulate eval_gettext() there. If neither are present we'll use a dumb printf(1) fall-through wrapper. = About libcharset.h and langinfo.h We use libcharset to query the character set of the current locale if it's available. I.e. we'll use it instead of nl_langinfo if HAVE_LIBCHARSET_H is set. The GNU gettext manual recommends using langinfo.h's nl_langinfo(CODESET) to acquire the current character set, but on systems that have libcharset.h's locale_charset() using the latter is either saner, or the only option on those systems. GNU and Solaris have a nl_langinfo(CODESET), FreeBSD can use either, but MinGW and some others need to use libcharset.h's locale_charset() instead. =Credits This patch is based on work by Jeff Epler <jepler@unpythonic.net> who did the initial Makefile / C work, and a lot of comments from the Git mailing list, including Jonathan Nieder, Jakub Narebski, Johannes Sixt, Erik Faye-Lund, Peter Krefting, Junio C Hamano, Thomas Rast and others.

So now C99-challenged platforms can build git without provoking warnings or errors from printf, even if pointers do not have the same size as an int or long.

2011-02-14configure: use AC_LANG_PROGRAM consistentlyLibravatar Ralf Wildenhues1-37/+19
Avoid warnings from Autoconf 2.68 about missing use of AC_LANG_PROGRAM and friends. Quoting autoconf-2.68/NEWS: ** The macros AC_PREPROC_IFELSE, AC_COMPILE_IFELSE, AC_LINK_IFELSE, and AC_RUN_IFELSE now warn if the first argument failed to use AC_LANG_SOURCE or AC_LANG_PROGRAM to generate the conftest file contents. A new macro AC_LANG_DEFINES_PROVIDED exists if you have a compelling reason why you cannot use AC_LANG_SOURCE but must avoid the warning. The underlying reason for that change is that AC_LANG_{SOURCE,PROGRAM} take care to supply the previously computed set of #defines (and include standard headers if so desired) for preprocessed languages like C and C++. In some cases, AC_LANG_PROGRAM is already used but not sufficiently m4-quoted, so we just need to add another set of [quotes] to prevent the autoconf warning from being triggered bogusly. Quoting all arguments (except when calling special macros that need to be expanded before recursion) is better style, anyway. These and more rules are described in detail in 'info Autoconf "Programming in M4"'. No change in the resulting config.mak.autogen after running ./configure intended.

When the ASCIIDOC8 and ASCIIDOC_NO_ROFF knobs were built, many people were still on asciidoc 7 and using older versions of docbook-xsl. These days, even the almost 2-year-old Debian stable needs these knobs turned. So let's turn them by default. The new knobs ASCIIDOC7 and ASCIIDOC_ROFF can be used to get the old behavior if people are on older systems.

2010-10-06Makefile & configure: add a NO_FNMATCH_CASEFOLD flagLibravatar Ævar Arnfjörð Bjarmason1-0/+22
On some platforms (like Solaris) there is a fnmatch, but it doesn't support the GNU FNM_CASEFOLD extension that's used by the jj/icase-directory series' fnmatch_icase wrapper. Change the Makefile so that it's now possible to set NO_FNMATCH_CASEFOLD=YesPlease on those systems, and add a configure probe for it. Unlike the NO_REGEX check we don't add AC_INCLUDES_DEFAULT to our headers. This is because on a GNU system the definition of FNM_CASEFOLD in fnmatch.h is guarded by: #if !defined _POSIX_C_SOURCE || _POSIX_C_SOURCE < 2 || defined _GNU_SOURCE One of the headers AC_INCLUDES_DEFAULT includes ends up defining one of those, so if we'd use it we'd always get NO_FNMATCH_CASEFOLD=YesPlease on GNU systems, even though they have FNM_CASEFOLD. When checking the flags we use: ifdef NO_FNMATCH ... else ifdef NO_FNMATCH_CASEFOLD ... endif endif The "else" so that we don't link against compat/fnmatch/fnmatch.o twice if both NO_FNMATCH and NO_FNMATCH_CASEFOLD are defined.

2010-10-06Makefile & configure: add a NO_FNMATCH flagLibravatar Ævar Arnfjörð Bjarmason1-0/+6
Windows and MinGW both lack fnmatch() in their C library and needed compat/fnmatch, but they had duplicate code for adding the compat function, and there was no Makefile flag or configure check for fnmatch. Change the Makefile it so that it's now possible to compile the compat function with a NO_FNMATCH=YesPlease flag, and add a configure probe for it.

2010-09-01Add global and system-wide gitattributesLibravatar Petr Onderka1-1/+9
Allow gitattributes to be set globally and system wide. This way, settings for particular file types can be set in one place and apply for all user's repositories. The location of system-wide attributes file is $(prefix)/etc/gitattributes. The location of the global file can be configured by setting core.attributesfile. Some parts of the code were copied from the implementation of the same functionality in config.c.

If the platform regex cannot match null bytes, we might as well use the glibc version instead.

Windows does not have strtok_r (and while it does have an identical strtok_s, but it is not obvious how to use it). Grab an implementation from glibc. The svn-fe tool uses strtok_r to parse paths.
