Subject: [RFC PATCH 0/4] Improvements to sha1_file
Date: Fri, 9 Jun 2017 12:23:22 -0700 [thread overview]
Message-ID: <cover.1497035376.git.jonathantanmy@google.com> (raw)
I was investigating how to adapt my existing patch for missing blob
support [1] to consult a manifest of missing blobs, and found it
difficult to further modify sha1_file.c without doing some further
refactoring. So here are some patches to do that.
I think patch 1 is an independently good change - it makes the code
clearer and is also a net reduction in lines. If none of the other
patches here make it, maybe patch 1 should go in independently.
Patches 2-3 are also collectively independent, but more invasive. The
commit messages explain what's going on in more detail, but basically
there are 3 functions doing similar things (getting information for an
object regardless of where it's stored) with duplicated mechanisms, and
for maintainability, it is better to combine them into one function.
Patch 4 is my adaptation of [1] after all the refactoring - notice that
I just needed to edit 1 storage-agnostic object info function instead
of previously needing to edit 3. It is still a work in progress - the
code looks complete, but I would probably need to at least document the
missing blob manifest format. I am providing it here just to show the
effectiveness of the refactoring in patches 2-3.
I am hoping for reviews on patches 1-3 to be included into the tree.
