2021-12-15Merge branch 'ew/test-wo-fsync'Libravatar Junio C Hamano1-0/+5
Allow running our tests while disabling fsync. * ew/test-wo-fsync: tests: disable fsync everywhere
2021-10-29tests: disable fsync everywhereLibravatar Eric Wong1-0/+5
The "GIT_TEST_FSYNC" environment variable now exists for disabling fsync() even on packfiles and other "critical" data. Running "make test -j8 NO_SVN_TESTS=1" on a noisy 8-core system on an HDD, test runtime drops from ~4 minutes down to ~3 minutes. Using "GIT_TEST_FSYNC=1" re-enables fsync() for comparison purposes. SVN interopability tests are minimally affected since SVN will still use fsync in various places. This will also be useful for 3rd-party tools which create throwaway git repositories of temporary data, but remains undocumented for end users.

2021-09-01pkt-line: add stdio packet write functionsLibravatar Jacob Vosmaer1-0/+12
This adds three new functions to pkt-line.c: packet_fwrite, packet_fwrite_fmt and packet_fflush. Besides writing a pktline flush packet, packet_fflush also flushes the stdio buffer of the stream.

2021-06-05fsync(): be prepared to see EINTRLibravatar Junio C Hamano1-2/+3
Some platforms, like NonStop do not automatically restart fsync() when interrupted by a signal, even when that signal is setup with SA_RESTART. This can lead to test breakage, e.g., where "--progress" is used, thus SIGALRM is sent often, and can interrupt an fsync() syscall. Make sure we deal with such a case by retrying the syscall ourselves. Luckily, we call fsync() fron a single wrapper, fsync_or_die(), so the fix is fairly isolated. Reported-by: Randall S.

2018-04-11write_or_die.c: rename to use dashes in file nameLibravatar Stefan Beller1-0/+71
This is more consistent with the project style. The majority of Git's source files use dashes in preference to underscores in their file names. Signed-off-by: Stefan Beller <sbeller@google.com>
