Package: git-buildpackage
Version: 0.8.8
Severity: normal

Hi,

today I ran "gbp pq export" in our Debian systemd git repository.
This generated quite a bit of churn, in the form of

-index f2d8bf5..7f2d731 100644
+index f2d8bf57f..7f2d73199 100644


This seems to be a result of using git 2.11.0 [1]:

  The default abbreviation length, which has historically been 7, now
  scales as the repository grows, using the approximate number of
  objects in the repository and a bit of math around the birthday
  paradox.  The logic suggests to use 12 hexdigits for the Linux
  kernel, and 9 to 10 for Git itself.

I wonder, whether gbp pq should setup a default core.abbrev=12 i.e.
something which is reasonably large and constant.

Regards,
Michael

Description: 
 git-buildpackage-rpm - Suite to help with RPM packages in Git repositories
 git-buildpackage - Suite to help with Debian packages in Git repositories
Changes:
 git-buildpackage (0.8.11) experimental; urgency=medium
 .
   * [8bd74df] command_wrappers: Simplify RunAtCommand
   * [1140886] buildpackage: Don't set a compression level if unset and make
     this the default.  This allows compressors to use the their default
     compression level. Only applies when not using pristine-tar.
     Thanks to Antoine Beaupré for investigating (Closes: #820846)
   * [0fdff8e] buildpackage: Use commit instead of tree to create archive.
     This makes sure we use the timestamps of the commit when creating the
     tarball. Only applies when not using pristine-tar
     Thanks to Ximin Luo for investigating (Closes: #851645)
   * [3f4b9f8] make: Check if we can use parallel flake
   * [534c055] git-pbuilder: Don't remove changes file (Closes: #850478)
   * [b863399] pull: Allow to specify remote on the command line
     (Closes: #851844)
   * [d3cb4db] gbp-posttag-push: add missing dry-run for debian branch push
   * [f9a7640] buildpackage: verify generated tarballs when using pristine-tar
   * [b8ea662] pq: Hardcode commit abbrev to 7 when exporting patches.
     This avoids path churn with git >= 2.11.0 (Closes: #848354)
   * Test suite enhancements
