annotate: do not construct attr.s object per line while computing history
Unfortunately, good abstraction has a cost. It's way slower to construct
an annotateline() object than creating a plain tuple or a list. This patch
changes the internal data structure from row-based to columnar, so the
decorate() function can be instant (i.e. no Python in hot loop.)
For code readability, the outermost tuple is switched to an attr.s object
instead.
(original, row-based attr.s)
$ hg annot mercurial/commands.py --time > /dev/null
time: real 11.470 secs (user 11.400+0.000 sys 0.070+0.000)
$ hg annot mercurial/commands.py --time --line-number > /dev/null
time: real 39.590 secs (user 39.500+0.000 sys 0.080+0.000)
(this patch, columnar)
$ hg annot mercurial/commands.py --time > /dev/null
time: real 11.780 secs (user 11.710+0.000 sys 0.070+0.000)
$ hg annot mercurial/commands.py --time --line-number > /dev/null
time: real 12.240 secs (user 12.170+0.000 sys 0.090+0.000)
(cf. 4.3.3, row-based tuple)
$ hg annot mercurial/commands.py --time --line-number > /dev/null
time: real 19.540 secs (user 19.460+0.000 sys 0.080+0.000)
====================================
Testing head checking code: Case A-4
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category A: simple case involving a branch being superceeded by another.
TestCase 4: New changeset as children of the successor
.. old-state:
..
.. * 1-changeset branch
..
.. new-state:
..
.. * 2-changeset branch, first is a successor, but head is new
