Subject: [RFC PATCH 2/4] builtin/repack.c: pass "cruft_expiration" to `write_cruft_pack`
Date: Wed, 29 Jun 2022 14:47:11 -0400	[thread overview]
Message-ID: <d346b65a43ba4f4c0c76f9483243e5277b411b11.1656528415.git.me@ttaylorr.com> (raw)
In-Reply-To: <cover.1656528343.git.me@ttaylorr.com>

`builtin/repack.c`'s `write_cruft_pack()` is used to generate the cruft
pack when `--cruft` is supplied. It uses a static variable
"cruft_expiration" which is filled in by option parsing.

A future patch will add an `--expire-to` option which allows `git
repack` to write a cruft pack containing the pruned objects out to a
separate repository. In order to implement this functionality, some
callers will have to pass a value for `cruft_expiration` different than
the one filled out by option parsing.

Prepare for this by teaching `write_cruft_pack` to take a
"cruft_expiration" parameter, instead of reading a single static
variable.

The (sole) existing caller of `write_cruft_pack()` will pass the value
for "cruft_expiration" filled in by option parsing, retaining existing
behavior. This means that we can make the variable local to
`cmd_repack()`, and eliminate the static declaration.
