credentials: add "cache" helper If you access repositories over smart-http using http authentication, then it can be annoying to have git ask you for your password repeatedly. We cache credentials in memory, of course, but git is composed of many small programs. Having to input your password for each one can be frustrating. This patch introduces a credential helper that will cache passwords in memory for a short period of time. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

unix-socket: add backlog size option to unix_stream_listen() Update `unix_stream_listen()` to take an options structure to override default behaviors. This commit includes the size of the `listen()` backlog. Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

unix-socket: disallow chdir() when creating unix domain sockets Calls to `chdir()` are dangerous in a multi-threaded context. If `unix_stream_listen()` or `unix_stream_connect()` is given a socket pathname that is too long to fit in a `sockaddr_un` structure, it will `chdir()` to the parent directory of the requested socket pathname, create the socket using a relative pathname, and then `chdir()` back. This is not thread-safe. Teach `unix_sockaddr_init()` to not allow calls to `chdir()` when this flag is set.
