Subject: [PATCH 1/2] fast-import: plug leak of dirty trees in 'ls' command
Date: Thu, 8 Mar 2012 14:31:39 -0600 [thread overview]
Message-ID: <20120308203139.GB8992@burratino> (raw)
In-Reply-To: <20120308202721.GA8992@burratino>
When the named directory has changed since it was last written to
pack, "tree_content_get" makes a deep copy of the list of tree entries
which we forgot to free.
This memory leak has been present since the "ls" command was
introduced in v1.7.5-rc0~3^2~33 (fast-import: add 'ls' command,
2010-12-02).
