Subject: repository: free main reference database
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=83f66846713850426bfce2a2b21567f55e647656;p=thirdparty%2Fgit.git

repository: free main reference database

While we release worktree and submodule reference databases when
clearing a repository, we don't ever release the main reference
database. This memory leak went unnoticed because its pointer is
kept alive by the "chdir_notify" subsystem.

Fix the memory leak.
