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.

The "simple-ipc" did not compile without pthreads support, but the build procedure was not properly account for it. * jh/simple-ipc-sans-pthread: simple-ipc: correct ifdefs when NO_PTHREADS is defined

simple-ipc: correct ifdefs when NO_PTHREADS is defined

2021-05-20T22:55:00Z

Simple IPC always requires threads (in addition to various platform-specific IPC support). Fix the ifdefs in the Makefile to define SUPPORTS_SIMPLE_IPC when appropriate. Previously, the Unix version of the code would only verify that Unix domain sockets were available. This problem was reported here: https://lore.kernel.org/git/YKN5lXs4AoK%2FJFTO@coredump.intra.peff.net/T/#m08be8f1942ea8a2c36cfee0e51cdf06489fdeafc Reported-by: Randall S.

Portability fix. * js/access-nul-emulation-on-windows: msvc: avoid calling `access("NUL", flags)`

msvc: avoid calling `access("NUL", flags)`

2021-04-16T19:05:32Z

Apparently this is not supported with Microsoft's Universal C Runtime. So let's not actually do that. Instead, just return success because we _know_ that we expect the `NUL` device to be present. Side note: it is possible to turn off the "Null device driver" and thereby disable `NUL`. Too many things are broken if this driver is disabled, therefore it is not worth bothering to try to detect its presence when `access()` is called.

Merge branch 'tb/precompose-prefix-simplify'

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
