From: Jeff King Date: Thu, 12 Jun 2014 22:05:37 +0000 (-0400) Subject: provide a helper to free commit buffer X-Git-Tag: v2.0.2~4^2~10 X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/0fb370da9ca972f9571530f95c0dacb31368c280?hp=0fb370da9ca972f9571530f95c0dacb31368c280 provide a helper to free commit buffer This converts two lines into one at each caller. But more importantly, it abstracts the concept of freeing the buffer, which will make it easier to change later. Note that we also need to provide a "detach" mechanism for a tricky case in index-pack. We are passed a buffer for the object generated by processing the incoming pack. If we are not using --strict, we just calculate the sha1 on that buffer and return, leaving the caller to free it. But if we are using --strict, we actually attach that buffer to an object, pass the object to the fsck functions, and then detach the buffer from the object again (so that the caller can free it as usual). In this case, we don't want to free the buffer ourselves, but just make sure it is no longer associated with the commit. Note that we are making the assumption here that the attach/detach process does not impact the buffer at all (e.g., it is never reallocated or modified). That holds true now, and we have no plans to change that. However, as we abstract the commit_buffer code, this dependency becomes less obvious. So when we detach, let's also make sure that we get back the same buffer that we gave to the commit_buffer code. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano ---
