Subject: [PATCH v3 00/30] Create a reference backend for packed refs
Date: Sat,  1 Jul 2017 20:30:38 +0200	[thread overview]
Message-ID: <cover.1498933362.git.mhagger@alum.mit.edu> (raw)

This is v3 of a patch series creating a `packed_ref_store` reference
backend. Thanks to Peff and Junio for their comments about v2 [1].

Changes since v2:

* Delete some debugging `cat` commands in t1408.

* Add some tests of reading packed-refs files with bogus contents.

* When reporting corruption in packed-refs files, distinguish between
  unterminated lines and other corruption.

* Fixed a typo in a commit message.

This patch series can also be obtained from my GitHub fork [2] as
branch packed-ref-store.
