This adds a new root hghave to test against. Almost all of these are a
subset of unix-permissions, but that is also used for checking exec
bit handling.
Previously the blackbox wrapped runcommand, but this failed to see the error
codes that were created if an exception occurred. I moved that logging to now
wrap _runcatch, so it can observe and log the actual error code (such as when
a user ctrl+c's during a command).
Updated the tests as well. Tested the change by running all the tests with the
blackbox extension enabled and verifying nothing broke (aside from things that
printed what extensions were enabeld).
The progress tests are affected by calls to time.time() so they needed to be
updated to pass.
The windows and vfat test runs were failing due to read/write permissions not
working the same on those systems. On vfat, permissions can't be changed
at all, and on windows it seems the chmod emulation doesn't remove read
permissions. We could theoretically get the 'cannot write to blacklog.log'
test to pass on windows but there's no #if condition to let us exclude vfat
only.
Verified that test-blackbox passes on windows now.
If enabled, log rotation prevents the amount of space used by the
blackbox log from growing without bound. This becomes important in
cases where there are a lot of busy repositories managed by humans
and automation on many machines.
In large deployments, we cannot reasonably track all the repos where
blackbox logs need to be managed, so it is safer to have blackbox
manage its own logs than to move responsibility to an external tool
such as logrotate.
This change adds two configuration keys:
* blackbox.maxsize is the maximum allowable size of the current log
* blackbox.maxfiles is the number of log files to maintain
Writes the backup bundle paths to the blackbox so it's easy to see which
backup bundle is associated with which command when you are debugging an
issue.
Example output:
2013/03/13 10:39:56 durham> strip tip
2013/03/13 10:39:59 durham> saved backup bundle to /data/users/durham/www-hg/.hg/strip-backup/e5fac262363a-backup.hg
2013/03/13 10:40:03 durham> strip tip exited 0 after 7.97 seconds
The blackbox was logging every head after every incoming group.
Now we only log the heads that have changed.
Added a test. Moved the hooks test to the bottom of the file since
the hooks interfer with the tests after it.
