tests: inform on Windows about unnecessary glob lines When glob lines directly match on windows, "/" (and not "\") was output in the path on the line. No glob matching is necessary in this case. The test output will look like this (when 5 tests have passed and no 4 has an unnecessary glob): ... Info, unnecessary glob: info about some/thing (glob) ..

tests: quickly check if the glob line already matches the output This happens when a path with "/" as only glob char is matched on a non windows platform. (Currently one third of all glob matches.) The slowdown on windows and the speedup on other os are neglectable.

tests: append glob to filename output when required (windows) This lines were introduced in cd403d6d96ef and made the test fail on windows.

util: make ensuredirs safer against races

blackbox: only show new heads on incoming 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.

blackbox: fix copyright

blackbox: fix a failing pyflakes test

blackbox: tests for the blackbox extension A few tests to cover the blackbox extension. Covers commands, hooks, and incoming changes.

blackbox: adds a 'blackbox' command for viewing recent logs Adds a 'hg blackbox' command for viewing the latest entries in the blackbox log. By default it shows the last 10 entries, but -l allows the user to specify.

blackbox: log incoming changes via ui.log() Logs incoming changes to a repo to ui.log(). Includes the number of changes and the hashes of the heads after the new changes. Example log line: 2013/02/09 08:35:19 durham> 1 incoming changes - new heads: cb9a9f314b8b Currently the blackbox logs the unix user that is performing the push/pull. It would be nice to log the http authorized user as well so it works with hgweb, but that's outside the scope of this commit.

blackbox: logs python and extension hooks via ui.log() Logs python and extension hooks to ui.log() for viewing in the blackbox. Example log lines: 2013/02/09 08:35:19 durham> pythonhook-preupdate: hgext.eol.preupdate finished in 0.01 seconds 2013/02/09 08:35:19 durham> exthook-update: echo hooked finished in 0.02 seconds

blackbox: log the commands that are run Uses ui.log to log which commands are run, their exit code, the time taken, and any unhandled exceptions thrown. Example log lines: 2013/02/09 08:35:19 durham> add foo 2013/02/09 08:35:19 durham> add exited 0 after 0.02 seconds Updates the progress tests because they use a mocked time.time() which these changes affect.

blackbox: adds a blackbox extension Adds a blackbox extension that listens to ui.log() and writes the messages to .hg/blackbox.log. Future commits will use ui.log() to log commands, unhandled exceptions, incoming changes, and hooks. The extension defaults to logging everything, but can be configured via blackbox.track to only log certain events. Log lines are of the format: "date time user> message" Example log line: 2013/02/09 08:35:19 durham> 1 incoming changes - new heads: d84ced58aaa

scmutil: create directories in a race-safe way during update With the new parallel update code, it is possible for multiple workers to try to create a hierarchy of directories at the same time. This is hard to trigger in general, but most likely during initial checkout. To deal with these races, we introduce a new ensuredirs function whose contract is to ensure that a directory hierarchy exists - it will ignore a failure that implies that the desired directory already exists.
