Subject: [PATCH 00/20] object_id part 7
Date: Sat, 18 Mar 2017 21:19:34 +0000
Message-ID: <20170318211954.564030-1-sandals@crustytoothpaste.net> (raw)

This is part 7 in the continuing transition to use struct object_id.

This series focuses on two main areas: adding two constants for the
maximum hash size we'll be using (which will be suitable for allocating
memory) and converting struct sha1_array to struct oid_array.

The rationale for adding separate constants for allocating memory is
that with a new 256-bit hash function, we're going to need two different
items: a constant for allocating memory that's as large as the largest
hash, and a global variable telling us size the current hash is.  I've
opted to provide GIT_MAX_RAWSZ and GIT_MAX_HEXSZ for allocating memory,
and leave GIT_SHA1_RAWSZ and GIT_SHA1_HEXSZ as values that can be later
replaced by the aforementioned global.

Replacing struct sha1_array with struct oid_array necessarily involves
converting the shallow code, so I did that.  The structure now handles
objects of struct object_id.  While I renamed the documentation (since
people will search for that), I chose not to rename the sha1-array.[ch]
files or the test helper because I didn't think it was worth the hassle,
especially for people who don't have rename support turned on by
default.  Of course, if the consensus is that they should be, I'll do so
in v2.

I chose to use Coccinelle quite a bit in this series, as it automates a
lot of the manual work and aides in review.  There is also some use of
Perl one-liners.

This series is available at https://github.com/bk2204/git under
object-id-part7; it may be rebased.  Future series are available in
various states as the object-id-part8, object-id-part9, and
object-id-part10 series.
