Subject: [PATCH v5 03/11] maintenance: replace run_auto_gc()
Date: Thu, 17 Sep 2020 18:11:44 +0000	[thread overview]
Message-ID: <3cbdeeafb56d0cddabbcef7d9ac301704e2616e6.1600366313.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.695.v5.git.1600366313.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The run_auto_gc() method is used in several places to trigger a check
for repo maintenance after some Git commands, such as 'git commit' or
'git fetch'.

To allow for extra customization of this maintenance activity, replace
the 'git gc --auto [--quiet]' call with one to 'git maintenance run
--auto [--quiet]'. As we extend the maintenance builtin with other
steps, users will be able to select different maintenance activities.

Rename run_auto_gc() to run_auto_maintenance() to be clearer what is
happening on this call, and to expose all callers in the current diff.
Rewrite the method to use a struct child_process to simplify the calls
slightly.

Since 'git fetch' already allows disabling the 'git gc --auto'
subprocess, add an equivalent option with a different name to be more
descriptive of the new behavior: '--[no-]maintenance'. Update the
documentation to include these options at the same time.
