Add a function to determine whether a path is owned by the current user

2022-03-21T12:16:26Z

This function will be used in the next commit to prevent `setup_git_directory()` from discovering a repository in a directory that is owned by someone other than the current user. Note: We cannot simply use `st.st_uid` on Windows just like we do on Linux and other Unix-like platforms: according to https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/stat-functions this field is always zero on Windows (because Windows' idea of a user ID does not fit into a single numerical value). Therefore, we have to do something a little involved to replicate the same functionality there. Also note: On Windows, a user's home directory is not actually owned by said user, but by the administrator. For all practical purposes, it is under the user's control, though, therefore we pretend that it is owned by the user. Signed-off-by: Johannes Schindelin

mingw: avoid fallback for {local,gm}time_r()

2022-03-17T11:52:12Z

mingw-w64's pthread_unistd.h had a bug that mistakenly (because there is no support for the *lockfile() functions required[1]) defined _POSIX_THREAD_SAFE_FUNCTIONS and that was being worked around since 3ecd153a3b (compat/mingw: support MSys2-based MinGW build, 2016-01-14). The bug was fixed in winphtreads, but as a side effect, leaves the reentrant functions from time.h no longer visible and therefore breaks the build. Since the intention all along was to avoid using the fallback functions, formalize the use of POSIX by setting the corresponding feature flag and compile out the implementation for the fallback functions.

Streamline the codepath to fix the UTF-8 encoding issues in the argv[] and the prefix on macOS. * tb/precompose-prefix-simplify: macOS: precompose startup_info->prefix precompose_utf8: make precompose_string_if_needed() public

precompose_utf8: make precompose_string_if_needed() public

2021-04-06T00:30:04Z

commit 5c327502 (MacOS: precompose_argv_prefix(), 2021-02-03) uses the function precompose_string_if_needed() internally. It is only used from precompose_argv_prefix() and therefore static in compat/precompose_utf8.c Expose this function, it will be used in the next commit. While there, allow passing a NULL pointer, which will return NULL. Signed-off-by: Torsten Bögershausen Signed-off-by: Junio C Hamano

Merge branch 'jk/open-dotgitx-with-nofollow'

2021-03-22T21:00:22Z

It does not make sense to make ".gitattributes", ".gitignore" and ".mailmap" symlinks, as they are supposed to be usable from the object store (think: bare repositories where HEAD:.mailmap etc. are used). When these files are symbolic links, we used to read the contents of the files pointed by them by mistake, which has been corrected. * jk/open-dotgitx-with-nofollow: mailmap: do not respect symlinks for in-tree .mailmap exclude: do not respect symlinks for in-tree .gitignore attr: do not respect symlinks for in-tree .gitattributes exclude: add flags parameter to add_patterns() attr: convert "macro_ok" into a flags field add open_nofollow() helper

git-compat-util.h: drop trailing semicolon from macro definition

2021-03-13T23:56:13Z

Make CALLOC_ARRAY usable like a function by requiring callers to supply the trailing semicolon, which all of the current ones already do. With the extra semicolon e.g. the following code wouldn't compile because it disconnects the "else" from the "if": if (condition) CALLOC_ARRAY(ptr, n); else whatever(); Signed-off-by: René Scharfe Signed-off-by: Junio C Hamano
