Subject: Prevent send-pack from segfaulting (backport from 'master')
X-Git-Tag: v1.5.3.5~9
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=b6c9fb5100f8cd4081f1c6df5aea7335a11e9659;p=git.git

Prevent send-pack from segfaulting (backport from 'master')

4491e62ae932d5774f628d1bd3be663c11058a73 (Prevent send-pack from
segfaulting when a branch doesn't match) is hereby cherry-picked
back to 'maint'.

If we can't find a source match, and we have no destination, we
need to abort the match function early before we try to match
the destination against the remote.
