[PATCH v5 26/36] hook: convert 'post-rewrite' hook in sequencer.c to hook.h

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Emily Shaffer <emilyshaffer@xxxxxxxxxx>

By using 'hook.h' for 'post-rewrite', we simplify hook invocations by
not needing to put together our own 'struct child_process'.

The signal handling that's being removed by this commit now takes
place in run-command.h:run_processes_parallel(), so it is OK to remove
them here.
