sha1_file: convert read_sha1_file to struct object_id

2018-03-14T16:23:50Z

Convert read_sha1_file to take a pointer to struct object_id and rename it read_object_file. Do the same for read_sha1_file_extended. Convert one use in grep.c to use the new function without any other code change, since the pointer being passed is a void pointer that is already initialized with a pointer to struct object_id. Update the declaration and definitions of the modified functions, and apply the following semantic patch to convert the remaining callers: @@ expression E1, E2, E3; @@ - read_sha1_file(E1.hash, E2, E3) + read_object_file(&E1, E2, E3) @@ expression E1, E2, E3; @@ - read_sha1_file(E1->hash, E2, E3) + read_object_file(E1, E2, E3) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1.hash, E2, E3, E4) + read_object_file_extended(&E1, E2, E3, E4) @@ expression E1, E2, E3, E4; @@ - read_sha1_file_extended(E1->hash, E2, E3, E4) + read_object_file_extended(E1, E2, E3, E4) Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

xdiff-interface: export comparing and hashing strings

2017-10-26T02:23:22Z

This will turn out to be useful in a later patch. xdl_recmatch is exported in xdiff/xutils.h, to be used by various xdiff/*.c files, but not outside of xdiff/. This one makes it available to the outside, too. While at it, add documentation. Signed-off-by: Stefan Beller Signed-off-by: Junio C Hamano

Merge branch 'bw/config-h'

2017-06-24T21:28:41Z

Fix configuration codepath to pay proper attention to commondir that is used in multi-worktree situation, and isolate config API into its own header file. * bw/config-h: config: don't implicitly use gitdir or commondir config: respect commondir setup: teach discover_git_directory to respect the commondir config: don't include config.h by default config: remove git_config_iter config: create config.h

config: don't include config.h by default

2017-06-15T19:56:22Z

Stop including config.h by default in cache.h. Instead only include config.h in those files which require use of the config system. Signed-off-by: Brandon Williams Signed-off-by: Junio C Hamano

Merge branch 'js/regexec-buf'

2016-09-26T23:09:19Z

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: use regexec_buf()

2016-09-21T20:56:15Z

The new regexec_buf() function operates on buffers with an explicitly specified length, rather than NUL-terminated strings. We need to use this function whenever the buffer we want to pass to regexec(3) may have been mmap(2)ed (and is hence not NUL-terminated). Note: the original motivation for this patch was to fix a bug where `git diff -G ` would crash. This patch converts more callers, though, some of which allocated to construct NUL-terminated strings, or worse, modified buffers to temporarily insert NULs while calling regexec(3). By converting them to use regexec_buf(), the code has become much cleaner. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

Convert read_mmblob to take struct object_id.

Since all of its callers have been updated, convert read_mmblob to take a pointer to struct object_id. Signed-off-by: brian m. carlson Signed-off-by: Junio C Hamano

xdiff: don't trim common tail with -W

2016-05-31T20:08:56Z

The function trim_common_tail() exits early if context lines are requested. If -U0 and -W are specified together then it can still trim context lines that might belong to a changed function. As a result that function is shown incompletely. Fix that by calling trim_common_tail() only if no function context or fixed context is requested. The parameter ctx is no longer needed now; remove it. While at it fix an outdated comment as well. Signed-off-by: Rene Scharfe Signed-off-by: Junio C Hamano

convert trivial cases to ALLOC_ARRAY

2016-02-22T22:51:09Z

Each of these cases can be converted to use ALLOC_ARRAY or REALLOC_ARRAY, which has two advantages: 1. It automatically checks the array-size multiplication for overflow. 2. It always uses sizeof(*array) for the element-size, so that it can never go out of sync with the declared type of the array. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano
