[PATCH 1/2] object-file: lift ODB reprepare out of packfile flush

From
Justin Tobler <jltobler@gmail.com>
Date
Sep 13, 2026, 20:26 UTC
Message-ID
<cf14416f224f48475dfc9f79d8ec62756b9fdedf.1789328612.git.jltobler@gmail.com>
In-Reply-To
<cover.1789328612.git.jltobler@gmail.com>

When flushing a packfile via `flush_packfile_transaction()`, `odb_reprepare()` is invoked so the written packfile becomes visible in the current process. In a subsequent commit, repreparing the ODB is slightly deferred when committing a "files" ODB transaction.

Lift ODB reprepare out of `flush_packfile_transaction()` and instead require callers to explicitly invoke `odb_reprepare()` if required.
