From: Dave Borowitz Date: Tue, 1 Aug 2017 12:53:33 +0000 (-0400) Subject: Support force writing reflog on a per-update basis X-Git-Tag: v4.9.0.201710071750-r~7 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=refs%2Fchanges%2F96%2F102396%2F5;p=jgit.git Support force writing reflog on a per-update basis Even if a repository has core.logAllRefUpdates=true, ReflogWriter does not create reflog files unless the refs are under a hard-coded list of prefixes, or unless the forceWrite bit is set. Expose the forceWrite bit on a per-update basis in RefUpdate/BatchRefUpdate/ReceiveCommand, creating RefLogWriters as necessary.
