git-compat-util.h: remove unneccessary include of wildmatch.h

2023-06-21T20:39:54Z

The include of wildmatch.h in git-compat-util.h was added in cebcab189aa (Makefile: add USE_WILDMATCH to use wildmatch as fnmatch, 2013-01-01) as a way to be able to compile-time force any calls to fnmatch() to instead invoke wildmatch(). The defines and inline function were removed in 70a8fc999d9 (stop using fnmatch (either native or compat), 2014-02-15), and this include in git-compat-util.h has been unnecessary ever since. Remove the include from git-compat-util.h, but add it to the .c files that had omitted the direct #include they needed. Signed-off-by: Elijah Newren Signed-off-by: Junio C Hamano

wildmatch: remove unused wildopts parameter

2017-06-24T01:27:07Z

Remove the unused wildopts placeholder struct from being passed to all wildmatch() invocations, or rather remove all the boilerplate NULL parameters. This parameter was added back in commit 9b3497cab9 ("wildmatch: rename constants and update prototype", 2013-01-01) as a placeholder for future use. Over 4 years later nothing has made use of it, let's just remove it. It can be added in the future if we find some reason to start using such a parameter.

use QSORT

2016-09-29T22:42:18Z

Apply the semantic patch contrib/coccinelle/qsort.cocci to the code base, replacing calls of qsort(3) with QSORT. The resulting code is shorter and supports empty arrays with NULL pointers. 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

Merge branch 'nd/no-more-fnmatch'

2014-03-14T21:25:31Z

We started using wildmatch() in place of fnmatch(3); complete the process and stop using fnmatch(3). * nd/no-more-fnmatch: actually remove compat fnmatch source code stop using fnmatch (either native or compat) Revert "test-wildmatch: add "perf" command to compare wildmatch and fnmatch" use wildmatch() directly without fnmatch() wrapper

diffcore-order: export generic ordering interface

2014-02-24T22:44:57Z

diffcore_order() interface only accepts a queue of `struct diff_filepair`. In the next patches, we'll want to order `struct combine_diff_path` by path, so let's first rework diffcore-order to also provide generic low-level interface for ordering arbitrary objects, provided they have path accessors. The new interface is: - `struct obj_order` for describing objects to ordering routine, and - order_objects() for actually doing the ordering work.

use wildmatch() directly without fnmatch() wrapper

Make it clear that we don't use fnmatch() anymore. Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

Merge branch 'sb/diff-orderfile-config'

2014-01-10T18:32:42Z

Allow "git diff -O" to be configured with a new configuration variable. * sb/diff-orderfile-config: diff: add diff.orderfile configuration variable diff: let "git diff -O" read orderfile from any file and fail properly t4056: add new tests for "git diff -O"

diff: let "git diff -O" read orderfile from any file and fail properly

2013-12-19T00:29:05Z

The -O flag really shouldn't silently fail to do anything when given a path that it can't read from. However, it should be able to read from un-mmappable files, such as: * pipes/fifos * /dev/null: It's a character device (at least on Linux) * ANY empty file: Quoting Linux mmap(2), "SUSv3 specifies that mmap() should fail if length is 0. However, in kernels before 2.6.12, mmap() succeeded in this case: no mapping was created and the call returned addr. Since kernel 2.6.12, mmap() fails with the error EINVAL for this case." We especially want "-O/dev/null" to work, since we will be documenting it as the way to cancel "diff.orderfile" when we add that. (Note: "-O/dev/null" did have the right effect, since the existing error handling essentially worked out to "silently ignore the orderfile". But this was probably more coincidence than anything else.) So, lets toss all of that logic to get the file mmapped and just use strbuf_read_file() instead, which gives us decent error handling practically for free.
