This patch series implements an entirely alternate method of achieving
some of the same ends as the MIDX, using the approach suggested by
Jeff King from the RFC thread back in January[1]. You can now do:
core.abbrev = 20
core.validateAbbrev = false
Or:
core.abbrev = +2
core.validateAbbrev = false
On linux.git `git log --oneline --raw --parents` with 64MB packs gives
this improvement with core.abbrev=15 & core.validateAbbrev=false
(v.s. true):
Test HEAD~ HEAD
----------------------------------------------------------------------------------------
0014.1: git log --oneline --raw --parents 95.68(95.07+0.53)
42.74(42.33+0.39) -55.3%
While cleaning up the RFC version of this which I sent in [2] I
discovered that almost none of the existing functionality was tested
for, and was very inconsistent since we have 4 different places where
the abbrev config is parsed.
See 19/20 and 20/20 for what this whole thing is building towards, the
rest is all tests, cleanup, and preparatory work.
(There's still other long-standing issues with the existing behavior
which this doesn't change, but I had to stop somewhere to make this
digestible).
