In 1119a15b5c8 (http: drop support for curl < 7.11.1, 2021-07-30) support for curl versions older than 7.11.1 was removed, and we currently require at least version 7.19.4, see 644de29e220 (http: drop support for curl < 7.19.4, 2021-07-30). In those changes this Makefile-specific check added in 0890098780f (Decide whether to build http-push in the Makefile, 2005-11-18) was missed, now that we're never going to use such an ancient curl version we don't need to check that we have at least 7.9.8 here. I have no idea what in http-push.c broke on versions older than that. This does not impact "NO_CURL" setups, as this is in the "else" branch after that check.

2021-09-05make: add INSTALL_STRIP option variableLibravatar Bagas Sanjaya1-3/+12
Add $(INSTALL_STRIP), which allows passing stripping options to $(INSTALL). For this to work, installing executables must be split to installing compiled binaries and scripts portions, since $(INSTALL_STRIP) is only meaningful to the former. Users can set this variable depending on their system. For example, Linux users can use `-s --strip-program=strip`, while FreeBSD users can simply set to `-s` and choose strip program with $STRIPBIN.

2021-09-03developer: enable pedantic by defaultLibravatar Carlo Marcelo Arenas Belón1-2/+2
With the codebase firmly C99 compatible and most compilers supporting newer versions by default, it could help bring visibility to problems. Reverse the DEVOPTS=pedantic flag to provide a fallback for people stuck with gcc < 5 or some other compiler that either doesn't support this flag or has issues with it, and while at it also enable -Wpedantic which used to be controversial[1] when Apple compilers and clang had widely divergent version numbers. Ideally any compiler found to have issues with these flags will be added to an exception, and indeed, one was added to safely process windows headers that would use non standard print identifiers, but it is expected that more will be needed, so it could be considered a weather balloon.

2021-09-03gettext: remove optional non-standard parens in N_() definitionLibravatar Ævar Arnfjörð Bjarmason1-19/+1
Remove the USE_PARENS_AROUND_GETTEXT_N compile-time option which was meant to catch an inadvertent mistake which is too obscure to maintain this facility. The backstory of how USE_PARENS_AROUND_GETTEXT_N came about is: When I added the N_() macro in 65784830366 (i18n: add no-op _() and N_() wrappers, 2011-02-22) it was defined as: #define N_(msgid) (msgid) This is non-standard C, as was noticed and fixed in 642f85faab2 (i18n: avoid parenthesized string as array initializer, 2011-04-07). I.e. this needed to be defined as: #define N_(msgid) msgid Then in e62cd35a3e8 (i18n: log: mark parseopt strings for translation, 2012-08-20) when "builtin_log_usage" was marked for translation the string concatenation for passing to usage() added in 1c370ea4e51 (Show usage string for 'git log -h', 'git show -h' and 'git diff -h', 2009-08-06) was faithfully preserved: - "git log [<options>] [<since>..<until>] [[--] <path>...]\n" - " or: git show [options] <object>...", + N_("git log [<options>] [<since>..<until>] [[--] <path>...]\n") + N_(" or: git show [options] <object>..."), This was then fixed to be the expected array of usage strings in e66dc0cc4b1 (log.c: fix translation markings, 2015-01-06) rather than a string with multiple "\n"-delimited usage strings, and finally in 290c8e7a3fe (gettext.h: add parentheses around N_ expansion if supported, 2015-01-11) USE_PARENS_AROUND_GETTEXT_N was added to ensure this mistake didn't happen again. I think that even if this was a N_()-specific issue this USE_PARENS_AROUND_GETTEXT_N facility wouldn't be worth it, the issue would be too rare to worry about. But I also think that 290c8e7a3fe which introduced USE_PARENS_AROUND_GETTEXT_N misattributed the problem. The issue wasn't with the N_() macro added in e62cd35a3e8, but that before the N_() macro existed in the codebase the initial migration to parse_options() in 1c370ea4e51 continued passsing in a "\n"-delimited string, when the new API it was migrating to supported and expected the passing of an array.

2021-08-19Makefile: remove archives before manipulating them with 'ar'Libravatar SZEDER Gábor1-2/+2
The rules creating the $(LIB_FILE) and $(XDIFF_LIB) archives used to be: $(QUIET_AR)$(RM) $@ && $(AR) $(ARFLAGS) $@ $^ until commit 7b76d6bf22 (Makefile: add and use the ".DELETE_ON_ERROR" flag, 2021-06-29) removed the '$(RM) $@' part, claiming that "we can rely on the "c" (create) being present in ARFLAGS", and (I presume) assuming that it means that the named archive is created from scratch. Unfortunately, that's not what the 'c' flag does, it merely "Suppress the diagnostic message that is written to standard error by default when the archive is created" [1]. Consequently, all object files that are already present in an existing archive and are not replaced will remain there. This leads to linker errors in back-to-back builds of different revisions without a 'make clean' between them if source files going into these archives are renamed in between: # The last commit renaming files that go into 'libgit.a': # bc62692757 (hash-lookup: rename from sha1-lookup, 2020-12-31) # sha1-lookup.c => hash-lookup.c | 14 +++++++------- # sha1-lookup.h => hash-lookup.h | 12 ++++++------ $ git checkout bc62692757^ HEAD is now at 7a7d992d0d sha1-lookup: rename `sha1_pos()` as `hash_pos()` $ make [...] $ git checkout 7b76d6bf22 HEAD is now at 7b76d6bf22 Makefile: add and use the ".DELETE_ON_ERROR" flag $ make [...] AR libgit.a LINK git /usr/bin/ld: libgit.a(hash-lookup.o): in function `bsearch_hash': /home/szeder/src/git/hash-lookup.c:105: multiple definition of `bsearch_hash'; libgit.a(sha1-lookup.o):/home/szeder/src/git/sha1-lookup.c:105: first defined here collect2: error: ld returned 1 exit status make: *** [Makefile:2213: git] Error 1 Restore the original make rules to first remove $(LIB_FILE) and $(XDIFF_LIB) and then create them from scratch to avoid these build errors.

2021-08-05Makefile: normalize clobbering & xargs for tags targetsLibravatar Ævar Arnfjörð Bjarmason1-8/+9
Since the "tags", "TAGS" and "cscope.out" targets rely on piping into xargs with an "echo <list> | xargs" pattern, we need to make sure we're in an append mode. Unlike my recent change to make use of ".DELETE_ON_ERROR" in 7b76d6bf221 (Makefile: add and use the ".DELETE_ON_ERROR" flag, 2021-06-29), we really do need the "rm $@+" at the beginning (note, not "rm $@"). This is because the xargs command may decide to invoke the program multiple times. We need to make sure we've got a union of its results at the end. For "ctags" and "etags" we used the "-a" flag for this, for cscope that behavior is the default. Its "-u" flag disables its equivalent of an implicit "-a" flag. Let's also consistently use the $@ and $@+ names instead of needlessly hardcoding or referring to more verbose names in the "tags" and "TAGS" rules. These targets could perhaps be improved in the future by factoring this "echo <list> | xargs" pattern so that we make intermediate tags files for each source file, and then assemble them into one "tags" file at the end. The etags manual page suggests that doing that (or perhaps just --update) might be counter-productive, in any case, the tag building is fast enough for me, so I'm leaving that for now.

2021-08-05Makefile: remove "cscope.out", not "cscope*" in cscope.out targetLibravatar Ævar Arnfjörð Bjarmason1-2/+2
Before we generate a "cscope.out" file, remove that file explicitly, and not everything matching "cscope*". This doesn't change any behavior of the Makefile in practice, but makes this rule less confusing, and consistent with other similar rules. The cscope target was added in a2a9150bf06 (makefile: Add a cscope target, 2007-10-06). It has always referred to cscope* instead of to cscope.out in .gitignore and the "clean" target, even though we only ever generated a cscope.out file. This was seemingly done to aid use-cases where someone invoked cscope with the "-q" flag, which would make it create a "cscope.in.out" and "cscope.po.out" files in addition to "cscope.out". But us removing those files we never generated is confusing, so let's only remove the file we need to, furthermore let's use the "-f" flag to explicitly name the cscope.out file, even though it's the default if not "-f" argument is supplied. It is somewhat inconsistent to change from the glob here but not in the "clean" rule and .gitignore, an earlier version of this change updated those as well, but see [1][2] for why they were kept. 1. https://lore.kernel.org/git/87k0lit57x.fsf@evledraar.gmail.com/ 2. https://lore.kernel.org/git/87im0kn983.fsf@evledraar.gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-07-30t0001: fix broken not-quite getcwd(3) test in bed67874e2Libravatar Ævar Arnfjörð Bjarmason1-0/+1
With a54e938e5b (strbuf: support long paths w/o read rights in strbuf_getcwd() on FreeBSD, 2017-03-26) we had t0001 break on systems like OpenBSD and AIX whose getcwd(3) has standard (but not like glibc et al) behavior. This was partially fixed in bed67874e2 (t0001: skip test with restrictive permissions if getpwd(3) respects them, 2017-08-07). The problem with that fix is that while its analysis of the problem is correct, it doesn't actually call getcwd(3), instead it invokes "pwd -P". There is no guarantee that "pwd -P" is going to call getcwd(3), as opposed to e.g. being a shell built-in. On AIX under both bash and ksh this test breaks because "pwd -P" will happily display the current working directory, but getcwd(3) called by the "git init" we're testing here will fail to get it. I checked whether clobbering the $PWD environment variable would affect it, and it didn't. Presumably these shells keep track of their working directory internally. There's possible follow-up work here in teaching strbuf_getcwd() to get the working directory with whatever method "pwd" uses on these platforms. See [1] for a discussion of that, but let's take the easy way out here and just skip these tests by fixing the GETCWD_IGNORES_PERMS prerequisite to match the limitations of strbuf_getcwd(). 1. https://lore.kernel.org/git/b650bef5-d739-d98d-e9f1-fa292b6ce982@web.de/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2021-07-26tests: exercise the RUNTIME_PREFIX featureLibravatar Johannes Schindelin1-0/+5
Originally, we refrained from adding a regression test in 7b6c6496374 (system_path(): Add prefix computation at runtime if RUNTIME_PREFIX set, 2008-08-10), and in 226c0ddd0d6 (exec_cmd: RUNTIME_PREFIX on some POSIX systems, 2018-04-10). The reason was that it was deemed too tricky to test. Turns out that it is not tricky to test at all: we simply create a pseudo-root, copy the `git` executable into the `git/` subdirectory of that pseudo-root, then copy a script into the `libexec/git-core/` directory and expect that to be picked up.

To pave the way for non-Windows platforms to define trace2_collect_process_info(), reorganize the stub-or-definition schema to something which doesn't directly reference Windows. Platforms which want to collect parent process information in the future should: 1. Add an implementation to compat/ (e.g. compat/somearch/procinfo.c) 2. Add that object to COMPAT_OBJS to config.mak.uname (e.g. COMPAT_OBJS += compat/somearch/procinfo.o) 3. Define HAVE_PLATFORM_PROCINFO in config.mak.uname In the Windows case, this definition lives in compat/win32/trace2_win32_process_info.c, which is already conditionally added to COMPAT_OBJS; so let's add HAVE_PLATFORM_PROCINFO to hint to the build that compat/stub/procinfo.c should not be used.

2021-07-07oidtree: a crit-bit tree for odb_loose_cacheLibravatar Eric Wong1-0/+3
This saves 8K per `struct object_directory', meaning it saves around 800MB in my case involving 100K alternates (half or more of those alternates are unlikely to hold loose objects). This is implemented in two parts: a generic, allocation-free `cbtree' and the `oidtree' wrapper on top of it. The latter provides allocation using alloc_state as a memory pool to improve locality and reduce free(3) overhead. Unlike oid-array, the crit-bit tree does not require sorting. Performance is bound by the key length, for oidtree that is fixed at sizeof(struct object_id). There's no need to have 256 oidtrees to mitigate the O(n log n) overhead like we did with oid-array. Being a prefix trie, it is natively suited for expanding short object IDs via prefix-limited iteration in `find_short_object_filename'. On my busy workstation, p4205 performance seems to be roughly unchanged (+/-8%). Startup with 100K total alternates with no loose objects seems around 10-20% faster on a hot cache. (800MB in memory savings means more memory for the kernel FS cache). The generic cbtree implementation does impose some extra overhead for oidtree in that it uses memcmp(3) on "struct object_id" so it wastes cycles comparing 12 extra bytes on SHA-1 repositories. I've not yet explored reducing this overhead, but I expect there are many places in our code base where we'd want to investigate this.

Use the GNU make ".DELETE_ON_ERROR" flag in our main Makefile, as we already do in the Documentation/Makefile since db10fc6c09f (doc: simplify Makefile using .DELETE_ON_ERROR, 2021-05-21). Now if a command to make X fails X will be removed, the default behavior of GNU make is to only do so if "make" itself is interrupted with a signal. E.g. if we now intentionally break one of the rules with: - mv $@+ $@ + mv $@+ $@ && \ + false We'll get output like: $ make git CC git.o LINK git make: *** [Makefile:2179: git] Error 1 make: *** Deleting file 'git' $ file git git: cannot open `git' (No such file or directory) Before this change we'd leave the file in place in under this scenario. As in db10fc6c09f this allows us to remove patterns of removing leftover $@ files at the start of rules, since previous failing runs of the Makefile won't have left those littered around anymore. I'm not as confident that we should be replacing the "mv $@+ $@" pattern entirely, since that means that external programs or one of our other Makefiles might race and get partial content. I'm not changing $(REMOTE_CURL_ALIASES) since that uses a ln/ln -s/cp dance, and would require the addition of "-f" flags if the "rm" at the start was removed. I've also got plans to fix that ln/ln -s/cp pattern in another series. For $(LIB_FILE) and $(XDIFF_LIB) we can rely on the "c" (create) being present in ARFLAGS. I'm not changing "$(ETAGS_TARGET)", "tags" and "cscope" because they've got a messy combination of removing "$@+" not "$@" at the beginning, or "$@*". I'm also addressing those in another series.

2021-06-28promisor-remote: teach lazy-fetch in any repoLibravatar Jonathan Tan1-0/+1
This is one step towards supporting partial clone submodules. Even after this patch, we will still lack partial clone submodules support, primarily because a lot of Git code that accesses submodule objects does so by adding their object stores as alternates, meaning that any lazy fetches that would occur in the submodule would be done based on the config of the superproject, not of the submodule. This also prevents testing of the functionality in this patch by user-facing commands. So for now, test this mechanism using a test helper. Besides that, there is some code that uses the wrapper functions like has_promisor_remote(). Those will need to be checked to see if they could support the non-wrapper functions instead (and thus support any repository, not just the_repository).

2021-06-08t: use user-specified utf-8 locale for testing svnLibravatar Đoàn Trần Công Danh1-0/+7
In some test-cases, UTF-8 locale is required. To find such locale, we're using the first available UTF-8 locale that returned by "locale -a". However, the locale(1) utility is unavailable on some systems, e.g. Linux with musl libc. However, without "locale -a", we can't guess provided UTF-8 locale. Add a Makefile knob GIT_TEST_UTF8_LOCALE and activate it for linux-musl in our CI system. Rename t/lib-git-svn.sh:prepare_a_utf8_locale to prepare_utf8_locale, since we no longer prepare the variable named "a_utf8_locale", but set up a fallback value for GIT_TEST_UTF8_LOCALE instead. The fallback will be LC_ALL, LANG environment variable, or the first UTF-8 locale from output of "locale -a", in that order.

Simple IPC always requires threads (in addition to various platform-specific IPC support). Fix the ifdefs in the Makefile to define SUPPORTS_SIMPLE_IPC when appropriate. Previously, the Unix version of the code would only verify that Unix domain sockets were available.

Since 07d90eadb50 (Makefile: add Perl runtime prefix support, 2018-04-10) PERL_DEFINES has been a simply-expanded variable, let's make it recursively expanded instead. This change doesn't matter for the correctness of the logic. Whether we used simply-expanded or recursively expanded didn't change what we wrote out in GIT-PERL-DEFINES, but being consistent with other rules makes this easier to understand.

Change the logic of the i18n functions I added in 5e9637c6297 (i18n: add infrastructure for translating Git with gettext, 2011-11-18) to use pass-through functions when NO_GETTEXT is defined. This speeds up the compilation time of commands that use this library when NO_GETTEXT=Y is in effect.

Since 07d90eadb50 (Makefile: add Perl runtime prefix support, 2018-04-10) we have been declaring PERL_DEFINES right after assigning to it, with the effect that the first PERL_DEFINES was ignored. That bug didn't matter in practice since the first line had all the same variables as the second, so we'd correctly re-generate everything. It just made for confusing reading. Let's remove that first assignment, and while we're at it split these across lines to make them more maintainable.

2021-04-19parallel-checkout: make it truly parallelLibravatar Matheus Tavares1-0/+1
Use multiple worker processes to distribute the queued entries and call write_pc_item() in parallel for them. The items are distributed uniformly in contiguous chunks. This minimizes the chances of two workers writing to the same directory simultaneously, which could affect performance due to lock contention in the kernel. Work stealing (or any other format of re-distribution) is not implemented yet. The protocol between the main process and the workers is quite simple. They exchange binary messages packed in pkt-line format, and use PKT-FLUSH to mark the end of input (from both sides). The main process starts the communication by sending N pkt-lines, each corresponding to an item that needs to be written. These packets contain all the necessary information to load, smudge, and write the blob associated with each item. Then it waits for the worker to send back N pkt-lines containing the results for each item. The resulting packet must contain: the identification number of the item that it refers to, the status of the operation, and the lstat() data gathered after writing the file (iff the operation was successful). For now, checkout always uses a hardcoded value of 2 workers, only to demonstrate that the parallel checkout framework correctly divides and writes the queued entries. The next patch will add user configurations and define a more reasonable default, based on tests with the said settings.

2021-04-19unpack-trees: add basic support for parallel checkoutLibravatar Matheus Tavares1-0/+1
This new interface allows us to enqueue some of the entries being checked out to later uncompress them, apply in-process filters, and write out the files in parallel. For now, the parallel checkout machinery is enabled by default and there is no user configuration, but run_parallel_checkout() just writes the queued entries in sequence (without spawning additional workers). The next patch will actually implement the parallelism and, later, we will make it configurable. Note that, to avoid potential data races, not all entries are eligible for parallel checkout. Also, paths that collide on disk (e.g. case-sensitive paths in case-insensitive file systems), are detected by the parallel checkout code and skipped, so that they can be safely sequentially handled later. The collision detection works like the following: - If the collision was at basename (e.g. 'a/b' and 'a/B'), the framework detects it by looking for EEXIST and EISDIR errors after an open(O_CREAT | O_EXCL) failure. - If the collision was at dirname (e.g. 'a/b' and 'A'), it is detected at the has_dirs_only_path() check, which is done for the leading path of each item in the parallel checkout queue. Both verifications rely on the fact that, before enqueueing an entry for parallel checkout, checkout_entry() makes sure that there is no file at the entry's path and that its leading components are all real directories. So, any later change in these conditions indicates that there was a collision (either between two parallel-eligible entries or between an eligible and an ineligible one). After all parallel-eligible entries have been processed, the collided (and thus, skipped) entries are sequentially fed to checkout_entry() again. This is similar to the way the current code deals with collisions, overwriting the previously checked out entries with the subsequent ones. The only difference is that, since we no longer create the files in the same order that they appear on index, we are not able to determine which of the colliding entries will survive on disk (for the classic code, it is always the last entry).
