testrunner: fix updating of .testtimes file We attempt to write the 5 most recent test timings to a file called .testtimes, but we read previous results from a file called .testtimes- (including the hyphen), so we ended up no more than a single time per test. Differential Revision: https://phab.mercurial-scm.org/D1961

testrunner: make reading of test times work with #testcases Due to a bug that will be fixed in the next patch, we never actually read back .testcases, so we didn't notice that it could not be parsed successfully when there are #testcases tests. The parsing failed on lines like "test-amend-subrepo.t (case obsstore-off) 32.420" because we used a simple string.split() call and expected all parts but the first to be floating point numbers (and "(case" isn't, for example). Fix by using a regex instead. Differential Revision: https://phab.mercurial-scm.org/D1960

tests: allow [Errno] in output I'm not sure why, but my system is printing "[Errno -5]" before the "No address associated with hostname" message. I suspect a modern version of Python improved errno tracking or something. Add an "[Errno ...]" pattern as optional output to make the test pass.

setdiscovery: don't call "heads" wire command when heads specified Our custom server has too many heads to announce (one per code review, plus a public head), but it still lets the user request one of them by doing hg pull -r <some expression> After the client has resolved the expression to a set of nodeids by calling the "lookup" wire command, it will start the discovery phase. Before this patch, that doesn't take the requested heads into account and unconditionally calls the server's "heads" command to find all its heads. One consequence of that the "all remote heads known locally" case triggers if the client already had the public head and the user will see a "no changes found" message that's unrelated to the head they requested. That message confused me for a while. More imporantly, it also means that pullop.cgresult incorrectly (given our arguably misbehaving server) gets set to 0 (no changesets added), which confused some of our extensions. This patch makes it so the client skips the "heads" command if the user requested specific revisions. Since the "heads" command is normally batched with the first "known" command and calculating the list of heads is probably cheap, I don't expect much improvement in speed from this.

testrunner: on error, color the "(case xxx)" part the same as filename When using #testcases, the lines that read something like ERROR: test-split.t (case obsstore-off) output changed get colored red and the filename gets highlighted with a brighter red. This makes it harder to notice the "case obsstore-off" part, but it does seem important, so let's highlight it. Differential Revision: https://phab.mercurial-scm.org/D1959
