Subject: [PATCH 01/16] list-objects: mark tree as unparsed when we free its buffer
Date: Tue, 25 Jun 2013 01:22:58 +0200 [thread overview]
Message-ID: <1372116193-32762-2-git-send-email-tanoku@gmail.com> (raw)
In-Reply-To: <1372116193-32762-1-git-send-email-tanoku@gmail.com>
From: Jeff King <peff@peff.net>
We free the tree buffer during traversal to save memory.
However, we do not reset the "parsed" flag, which leaves a
landmine for the next person to use the tree. When they call
parse_tree it will do nothing, and they will segfault when
they try to access the buffer.
This hasn't mattered until now because most rev-list
traversals would exit the program immediately afterwards,
but the bitmap writer wants to access the trees twice.
