update-server-info: avoid needless overwrites Do not change the existing info/refs and objects/info/packs files if they match the existing content on the filesystem. This is intended to preserve mtime and make it easier for dumb HTTP pollers to rely on the If-Modified-Since header. Combined with stdio and kernel buffering; the kernel should be able to avoid block layer writes and reduce wear for small files. As a result, the --force option is no longer needed. So stop documenting it, but let it remain for compatibility (and debugging, if necessary). v3: perform incremental comparison while generating to avoid OOM with giant files. Remove documentation for --force. Signed-off-by: Eric Wong <e@80x24.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>

test_description='Test git update-server-info'
leak tests: mark some misc tests as passing with SANITIZE=leak As in 7ff24785cb7 (leak tests: mark some misc tests as passing with SANITIZE=leak, 2021-10-12) continue marking various miscellaneous tests as passing when git is compiled with SANITIZE=leak. They'll now be listed as running under the "GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI target).
