check-code: do not prepend "warning" to a failure message
The prefix has not been removed when this check changed from a warning to a
failure.
strip: make --keep option not set all dirstate times to 0
hg strip -k was using dirstate.rebuild() which reset all the dirstate
entries timestamps to 0. This meant that the next time hg status was
run every file was considered to be 'unsure', which caused it to do
expensive read operations on every filelog. On a repo with >150,000
files it took 70 seconds when everything was in memory. From a cold
cache it took several minutes.
The fix is to only reset files that have changed between the working
context and the destination context.
For reference, --keep means the working directory is left alone during
the strip. We have users wanting to use this operation to store their
work-in-progress as a commit on a branch while they go work on another
branch, then come back later and be able to uncommit that work and
continue working. They currently use 'git reset HARD^' to accomplish
this in git.
sshpeer: store subprocess so it cleans up correctly
When running 'hg pull --rebase', I was seeing this exception 100% of the
time as the python process was closing down:
Exception TypeError: TypeError("'NoneType' object is not callable",) in
<bound method Popen.__del__ of <subprocess.Popen object at 0x937c10>> ignored
By storing the subprocess on the sshpeer, the subprocess seems to clean up
correctly, and I no longer see the exception. I have no idea why this actually
works, but I get a 0% repro if I store the subprocess in self.subprocess,
and a 100% repro if I store None in self.subprocess.
Possibly related to issue 2240.
blackbox: fix exception when logging commands with format characters
When running commands like 'hg export -o mypatch-%N.patch', the blackbox
would throw an exception because it tried to format %N. This change
prevents it from trying to format the command string.
localrepo: always write the filtered phasecache when nodes are destroyed (
issue3827)
When the strip command is run, it calls repo.destroyed, which in turn checks if
we read _phasecache, and if we did calls filterunknown on it and flushes the
changes immediately. But in some cases, nothing causes _phasecache to be read,
so we miss out on this and the file remains the same on-disk.
Then a call to invalidate comes, which should refresh _phasecache if it
changed, but it didn't, so it keeps using the old one with the stripped
revision which causes an IndexError.
