[PATCH 08/10] run-command API & users: remove run_command_v_opt_tr2()

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

 



As noted in the preceding commit for run_command_v_opt_cd_env() that
function's users could more easily use the underlying run_command()
directly.

In the case of the "git.c" user that can be argued the other way,
given the slight line count increase here, but part of that's because
the "args" in "git.c" was being leaked, which we now don't have to
worry about.

That just leaves the spawn_daemon() user in "fsmonitor-ipc.c", it's
likewise slightly more verbose as a result, but by making it use
run_command() we can remove this entire part of the API. As noted in a
preceding commit run_command_v_opt*() should be aimed at handling
various common cases, not these one-offs.

The "fsmonitor-ipc.c" caller would be nicer with a hypothetical
run_command_l_opt_tr2(), but let's not maintain such a thing only for
it, as it would be its only user.
