Subject: [PATCH 4/4] diff-lib: parallelize run_diff_files for submodules
Date: Thu, 22 Sep 2022 23:29:47 +0000	[thread overview]
Message-ID: <20220922232947.631309-5-calvinwan@google.com> (raw)
In-Reply-To: <20220922232947.631309-1-calvinwan@google.com>

During the iteration of the index entries in run_diff_files, whenever
a submodule is found and needs its status checked, a subprocess is
spawned for it. Instead of spawning the subprocess immediately and
waiting for its completion to continue, hold onto all submodules and
relevant information in a list. Then use that list to create tasks for
run_processes_parallel. Finished subprocesses pipe their output to
status_finish which parses it and sets the relevant variables.

Add config option status.parallelSubmodules to set the maximum number
of parallel jobs.
