2012-05-10Merge branch 'jc/install-no-hardlinks'Libravatar Junio C Hamano1-1/+11
Your build platform may support hardlinks but you may prefer not to use them, e.g. when installing to DESTDIR to make a tarball and untarring on a filesystem that has poor support for hardlinks. The Makefile in git-gui project may need to learn to honor the same setting; it unconditionally creates git-citool by hardlinking git-gui. * jc/install-no-hardlinks: Makefile: NO_INSTALL_HARDLINKS
2012-05-07index-pack: support multithreaded delta resolvingLibravatar Nguyễn Thái Ngọc Duy1-1/+1
This puts delta resolving on each base on a separate thread, one base cache per thread. Per-thread data is grouped in struct thread_local. When running with nr_threads == 1, no pthreads calls are made. The system essentially runs in non-thread mode. An experiment on a Xeon 24 core machine with git.git shows that performance does not increase proportional to the number of cores. So by default, we use maximum 3 cores.

Document the default pager and editor chosen at compile time in the git-var(1) manpage so users curious about what command _this_ copy of git will fall back to when EDITOR, VISUAL, and PAGER are unset can find the answer quickly. In builds leaving those settings uncustomized, this patch makes the manpage continue to say "usually vi" and "usually less" so the formatted documentation is usable for a wide audience including users of custom builds that change those settings. If you would like your copy of the docs to be less noncommittal, you will need to set DEFAULT_PAGER=less and DEFAULT_EDITOR=vi explicitly.

2012-04-09xdiff: load full words in the inner loop of xdl_hash_recordLibravatar Thomas Rast1-0/+12
Redo the hashing loop in xdl_hash_record in a way that loads an entire 'long' at a time, using masking tricks to see when and where we found the terminating '\n'. I stole inspiration and code from the posts by Linus Torvalds around https://lkml.org/lkml/2012/3/2/452 https://lkml.org/lkml/2012/3/5/6 His method reads the buffers in sizeof(long) increments, and may thus overrun it by at most sizeof(long)-1 bytes before it sees the final newline (or hits the buffer length check). I considered padding out all buffers by a suitable amount to "catch" the overrun, but * this does not work for mmap()'d buffers: if you map 4096+8 bytes from a 4096 byte file, accessing the last 8 bytes results in a SIGBUS on my machine; and * it would also be extremely ugly because it intrudes deep into the unpacking machinery. So I adapted it to not read beyond the buffer at all. Instead, it reads the final partial word byte-by-byte and strings it together. Then it can use the same logic as before to finish the hashing. So far we enable this only on x86_64, where it provides nice speedup for diff-related work: Test origin/next tr/xdiff-fast-hash ----------------------------------------------------------------------------- 4000.1: log -3000 (baseline) 0.07(0.05+0.02) 0.08(0.06+0.02) +14.3% 4000.2: log --raw -3000 (tree-only) 0.37(0.33+0.04) 0.37(0.32+0.04) +0.0% 4000.3: log -p -3000 (Myers) 1.75(1.65+0.09) 1.60(1.49+0.10) -8.6% 4000.4: log -p -3000 --histogram 1.73(1.62+0.09) 1.58(1.49+0.08) -8.7% 4000.5: log -p -3000 --patience 2.11(2.00+0.10) 1.94(1.80+0.11) -8.1% Perhaps other platforms could also benefit.

2012-04-03Use SHELL_PATH from build system in run_command.c:prepare_shell_cmdLibravatar Ben Walton1-0/+7
During the testing of the 1.7.10 rc series on Solaris for OpenCSW, it was discovered that t7006-pager was failing due to finding a bad "sh" in PATH after a call to execvp("sh", ...). This call was setup by run_command.c:prepare_shell_cmd. The PATH in use at the time saw /opt/csw/bin given precedence to traditional Solaris paths such as /usr/bin and /usr/xpg4/bin. A package named schilyutils (Joerg Schilling's utilities) was installed on the build system and it delivered a modified version of the traditional Solaris /usr/bin/sh as /opt/csw/bin/sh. This version of sh suffers from many of the same problems as /usr/bin/sh. The command-specific pager test failed due to the broken "sh" handling ^ as a pipe character. It tried to fork two processes when it encountered "sed s/^/foo:/" as the pager command. This problem was entirely dependent on the PATH of the user at runtime. Possible fixes for this issue are: 1. Use the standard system() or popen() which both launch a POSIX shell on Solaris as long as _POSIX_SOURCE is defined. 2. The git wrapper could prepend SANE_TOOL_PATH to PATH thus forcing all unqualified commands run to use the known good tools on the system. 3. The run_command.c:prepare_shell_command() could use the same SHELL_PATH that is in the #! line of all all scripts and not rely on PATH to find the sh to run. Option 1 would preclude opening a bidirectional pipe to a filter script and would also break git for Windows as cmd.exe is spawned from system() (cf. v1.7.5-rc0~144^2, "alias: use run_command api to execute aliases, 2011-01-07). Option 2 is not friendly to users as it would negate their ability to use tools of their choice in many cases. Alternately, injecting SANE_TOOL_PATH such that it takes precedence over /bin and /usr/bin (and anything with lower precedence than those paths) as git-sh-setup.sh does would not solve the problem either as the user environment could still allow a bad sh to be found. (Many OpenCSW users will have /opt/csw/bin leading their PATH and some subset would have schilyutils installed.) Option 3 allows us to use a known good shell while still honouring the users' PATH for the utilities being run. Thus, it solves the problem while not negatively impacting either users or git's ability to run external commands in convenient ways. Essentially, the shell is a special case of tool that should not rely on SANE_TOOL_PATH and must be called explicitly. With this patch applied, any code path leading to run_command.c:prepare_shell_cmd can count on using the same sane shell that all shell scripts in the git suite use. Both the build system and run_command.c will default this shell to /bin/sh unless overridden.

2012-02-17Introduce a performance testing frameworkLibravatar Thomas Rast1-1/+21
This introduces a performance testing framework under t/perf/. It tries to be as close to the test-lib.sh infrastructure as possible, and thus should be easy to get used to for git developers. The following points were considered for the implementation: 1. You usually want to compare arbitrary revisions/build trees against each other. They may not have the performance test under consideration, or even the perf-lib.sh infrastructure. To cope with this, the 'run' script lets you specify arbitrary build dirs and revisions. It even automatically builds the revisions if it doesn't have them at hand yet. 2. Usually you would not want to run all tests. It would take too long anyway. The 'run' script lets you specify which tests to run; or you can also do it manually. There is a Makefile for discoverability and 'make clean', but it is not meant for real-world use. 3. Creating test repos from scratch in every test is extremely time-consuming, and shipping or downloading such large/weird repos is out of the question. We leave this decision to the user. Two different sizes of test repos can be configured, and the scripts just copy one or more of those (using hardlinks for the object store). By default it tries to use the build tree's git.git repository. This is fairly fast and versatile. Using a copy instead of a clone preserves many properties that the user may want to test for, such as lots of loose objects, unpacked refs, etc. Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-02-13Makefile: Change the default compiler from "gcc" to "cc"Libravatar Ævar Arnfjörð Bjarmason1-1/+1
Ever since the very first commit to git.git we've been setting CC to "gcc". Presumably this is behavior that Linus copied from the Linux Makefile. However unlike Linux Git is written in ANSI C and supports a multitude of compilers, including Clang, Sun Studio, xlc etc. On my Linux box "cc" is a symlink to clang, and on a Solaris box I have access to "cc" is Sun Studio's CC. Both of these are perfectly capable of compiling Git, and it's annoying to have to specify CC=cc on the command-line when compiling Git when that's the default behavior of most other portable programs. So change the default to "cc". Users who want to compile with GCC can still add "CC=gcc" to the make(1) command-line, but those users who don't have GCC as their "cc" will see expected behavior, and as a bonus we'll be more likely to smoke out new compilation warnings from our distributors since they'll me using a more varied set of compilers by default.

2012-02-06Fix build problems related to profile-directed optimizationLibravatar Theodore Ts'o1-18/+35
There was a number of problems I ran into when trying the profile-directed optimizations added by Andi Kleen in git commit 7ddc2710b9. (This was using gcc 4.4 found on many enterprise distros.) 1) The -fprofile-generate and -fprofile-use commands are incompatible with ccache; the code ends up looking in the wrong place for the gcda files based on the ccache object names. 2) If the makefile notices that CFLAGS are different, it will rebuild all of the binaries. Hence the recipe originally specified by the INSTALL file ("make profile-all" followed by "make install") doesn't work. It will appear to work, but the binaries will end up getting built with no optimization. This patch fixes this by using an explicit set of options passed via the PROFILE variable then using this to directly manipulate CFLAGS and EXTLIBS. The developer can run "make PROFILE=BUILD all ; sudo make PROFILE=BUILD install" automatically run a two-pass build with the test suite run in between as the sample workload for the purpose of recording profiling information to do the profile-directed optimization. Alternatively, the profiling version of binaries can be built using: make PROFILE=GEN PROFILE_DIR=/var/cache/profile all make PROFILE=GEN install and then after git has been used for a while, the optimized version of the binary can be built as follows: make PROFILE=USE PROFILE_DIR=/var/cache/profile all make PROFILE=USE install Signed-off-by: "Theodore Ts'o" <tytso@mit.edu> Cc: Andi Kleen <ak@linux.intel.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2012-01-27Merge branch 'svn-fe' of git://repo.or.cz/git/jrn into jn/svn-feLibravatar Junio C Hamano1-19/+40
This simplifies svn-fe a great deal and fulfills a longstanding wish: support for dumps with deltas in them, and incremental imports. The cost is that commandline usage of the svn-fe tool becomes a little more complicated since it no longer keeps state itself but instead reads blobs back from fast-import in order to copy them between revisions and apply deltas to them. Also removes a couple of custom data structures and replaces them with strbufs like other parts of Git. * 'svn-fe' of git://repo.or.cz/git/jrn: (32 commits) vcs-svn: reset first_commit_done in fast_export_init vcs-svn: do not initialize report_buffer twice vcs-svn: avoid hangs from corrupt deltas vcs-svn: guard against overflow when computing preimage length vcs-svn: cap number of bytes read from sliding view test-svn-fe: split off "test-svn-fe -d" into a separate function vcs-svn: implement text-delta handling vcs-svn: let deltas use data from preimage vcs-svn: let deltas use data from postimage vcs-svn: verify that deltas consume all inline data vcs-svn: implement copyfrom_data delta instruction vcs-svn: read instructions from deltas vcs-svn: read inline data from deltas vcs-svn: read the preimage when applying deltas vcs-svn: parse svndiff0 window header vcs-svn: skeleton of an svn delta parser vcs-svn: make buffer_read_binary API more convenient vcs-svn: learn to maintain a sliding view of a file Makefile: list one vcs-svn/xdiff object or header per line vcs-svn: avoid using ls command twice ...

2012-01-27i18n: Do not force USE_GETTEXT_SCHEME=fallthrough on NO_GETTEXTLibravatar Junio C Hamano1-1/+1
It should merely be the default used when the builder does not say anything about USE_GETTEXT_SCHEME. Even with NO_GETTEXT, USE_GETTEXT_SCHEME=gnu may be a way to avoid possibly slower emulation in our shell scripts.

2012-01-23add a Makefile switch to avoid gettext translation in shell scriptsLibravatar Alex Riesen1-1/+5
Some systems have gettext.sh (GNU gettext) installed, but it is either broken or misconfigured in such a way so its output is not usable. In case the users of these systems are unable or not interested in fixing them, setting the new Makefile switch should help: make USE_GETTEXT_SCHEME=fallthrough This will replace the translation routines with fallthrough versions, that does not use gettext from the platform.
