Subject: find_pack_entry(): do not keep packed_git pointer locally
X-Git-Tag: v1.7.9.2~14^2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/c01f51cc750dbd76e50919bf4e3b94e1b47d2e23?ds=inline;hp=c01f51cc750dbd76e50919bf4e3b94e1b47d2e23

find_pack_entry(): do not keep packed_git pointer locally

Commit f7c22cc (always start looking up objects in the last used pack
first - 2007-05-30) introduce a static packed_git* pointer as an
optimization.  The kept pointer however may become invalid if
free_pack_by_name() happens to free that particular pack.

Current code base does not access packs after calling
free_pack_by_name() so it should not be a problem. Anyway, move the
pointer out so that free_pack_by_name() can reset it to avoid running
into troubles in future.
