Merge branch 'js/regexec-buf' into maint

2016-09-29T23:49:45Z

Some codepaths in "git diff" used regexec(3) on a buffer that was mmap(2)ed, which may not have a terminating NUL, leading to a read beyond the end of the mapped region. This was fixed by introducing a regexec_buf() helper that takes a pair with REG_STARTEND extension. * js/regexec-buf: regex: use regexec_buf() regex: add regexec_buf() that can work on a non NUL-terminated string regex: -G feeds a non NUL-terminated string to regexec() and fails

regex: add regexec_buf() that can work on a non NUL-terminated string

2016-09-21T20:56:15Z

We just introduced a test that demonstrates that our sloppy use of regexec() on a mmap()ed area can result in incorrect results or even hard crashes. So what we need to fix this is a function that calls regexec() on a length-delimited, rather than a NUL-terminated, string. Happily, there is an extension to regexec() introduced by the NetBSD project and present in all major regex implementation including Linux', MacOSX' and the one Git includes in compat/regex/: by using the (non-POSIX) REG_STARTEND flag, it is possible to tell the regexec() function that it should only look at the offsets between pmatch[0].rm_so and pmatch[0].rm_eo. That is exactly what we need. Since support for REG_STARTEND is so widespread by now, let's just introduce a helper function that always uses it, and tell people on a platform whose regex library does not support it to use the one from our compat/regex/ directory.

Code cleanup. * rs/compat-strdup: compat: move strdup(3) replacement to its own file

add coccicheck make target

2016-09-15T19:23:37Z

Provide a simple way to run Coccinelle against all source files, in the form of a Makefile target. Running "make coccicheck" applies each .cocci file in contrib/coccinelle/ on all source files. It generates a .patch file for each .cocci file, containing the actual changes for effecting the transformations described by the semantic patches. Non-empty .patch files are reported. They can be applied to the work tree using "patch -p0", but should be checked to e.g. make sure they don't screw up formatting or create circular references. Coccinelle's diagnostic output (stderr) is piped into .log files. Linux has a much more elaborate make target of the same name; let's start nice and easy.

compat: move strdup(3) replacement to its own file

2016-09-07T17:41:45Z

Move our implementation of strdup(3) out of compat/nedmalloc/ and allow it to be used independently from USE_NED_ALLOCATOR. The original nedmalloc doesn't come with strdup() and doesn't need it. Only _users_ of nedmalloc need it, which was added when we imported it to our compat/ hierarchy. This reduces the difference of our copy of nedmalloc from the original, making it easier to update, and allows for easier testing and reusing of our version of strdup().

Merge branch 'ew/build-time-pager-tweaks'

2016-08-08T21:48:44Z

The build procedure learned PAGER_ENV knob that lists what default environment variable settings to export for popular pagers. This mechanism is used to tweak the default settings to MORE on FreeBSD. * ew/build-time-pager-tweaks: pager: move pager-specific setup into the build

Merge branch 'jk/pack-objects-optim'

2016-08-08T21:48:39Z

"git pack-objects" has a few options that tell it not to pack objects found in certain packfiles, which require it to scan .idx files of all available packs. The codepaths involved in these operations have been optimized for a common case of not having any non-local pack and/or any .kept pack. * jk/pack-objects-optim: pack-objects: compute local/ignore_pack_keep early pack-objects: break out of want_object loop early find_pack_entry: replace last_found_pack with MRU cache add generic most-recently-used list sha1_file: drop free_pack_by_name t/perf: add tests for many-pack scenarios

2016-08-08T21:21:43Z

Build clean-up. * nd/test-helpers: t/test-lib.sh: fix running tests with --valgrind Makefile: use VCSSVN_LIB to refer to svn library Makefile: drop extra dependencies for test helpers

pager: move pager-specific setup into the build

2016-08-04T20:51:02Z

Allowing PAGER_ENV to be set at build-time allows us to move pager-specific knowledge out of our build. This allows us to set a better default for FreeBSD more(1), which pretends not to understand ANSI color escapes if the MORE environment variable is left empty, but accepts the same variables as less(1) Originally-from: https://public-inbox.org/git/xmqq61piw4yf.fsf@gitster.dls.corp.google.com/ Helped-by: Junio C Hamano Helped-by: Jeff King Signed-off-by: Eric Wong Signed-off-by: Junio C Hamano
