Subject: Merge branch 'ps/refs-avoid-chdir-notify-reparent' into jch
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=227b9af17431ddd3825bba20c26711120bab68cf;p=thirdparty%2Fgit.git

Merge branch 'ps/refs-avoid-chdir-notify-reparent' into jch

The reference backends have been converted to always use absolute
paths internally. This allows dropping the calls to
`chdir_notify_reparent()` and fixes a memory leak in how the
reference database is constructed with an "onbranch" condition.

* ps/refs-avoid-chdir-notify-reparent:
  refs: protect against chicken-and-egg recursion
  refs/reftable: lazy-load configuration to fix chicken-and-egg
  reftable: split up write options
  refs/files: lazy-load configuration to fix chicken-and-egg
  refs: move parsing of "core.logAllRefUpdates" back into ref stores
  repository: free main reference database
  chdir-notify: drop unused `chdir_notify_reparent()`
  refs: unregister reference stores from "chdir_notify"
  setup: don't apply "GIT_REFERENCE_BACKEND" without a repository
  setup: stop applying repository format twice
  setup: inline `check_and_apply_repository_format()`
