test: split test-largefile.t in multiple file
The `test-largefiles.t` unified test is significantly longer (about 30%) than
any other tests in the mercurial test suite. As a result, its is alway the last
test my test runner is waiting for at the end of a run.
In practice, this means that `test-largefile.t` is wasting half a minute of my
life every times I'm running the mercurial test suites. This probably mean more
a few cumulated day by now.
I've finally decided to split it up in multiple smaller tests to bring it back in
reasonable length.
This changeset extracts independent test cases in two files. One dedicated to
wire protocole testing, and another one dedicated to all other tests that could
be independently extracted.
No test case were haltered in the making of this changeset.
Various timing available below. All timing have been done on a with 90 jobs on a
64 cores machine. Similar result are shown on firefly (20 jobs on 12 core).
General timing of the whole run
--------------------------------
We see a 25% real time improvement for no significant cpu time impact.
Before split:
real 2m1.149s
user 58m4.662s
sys 11m28.563s
After split:
real 1m31.977s
user 57m45.993s
sys 11m33.634s
Last test to finish (using run-test.py --time)
----------------------------------------------
test-largefile.t is now finishing at the same time than other slow tests.
Before split:
Time Test
119.280 test-largefiles.t
93.995 test-mq.t
89.897 test-subrepo.t
86.920 test-glog.t
85.508 test-rename-merge2.t
83.594 test-revset.t
79.824 test-keyword.t
78.077 test-mq-header-date.t
After split:
Time Test
90.414 test-mq.t
88.594 test-largefiles.t
85.363 test-subrepo.t
81.059 test-glog.t
78.927 test-rename-merge2.t
78.021 test-revset.t
77.777 test-command-template.t
Timing of largefile test themself
-----------------------------------
Running only tests prefixed with "test-largefiles".
No significant change in cumulated time.
Before:

58.673 test-largefiles.t
2.931 test-largefiles-cache.t
0.583 test-largefiles-small-disk.t
After:
