record: prevent commits that don't pick up dirty subrepo changes (issue6102)...
record: prevent commits that don't pick up dirty subrepo changes (issue6102) This path covers interactive mode for commit, amend, and shelve, as well as the deprecated record extension. Since shelf creation uses commit without -S in the non-interactive case, aborting here should be OK. (I didn't check what happens to non interactive shelve creation if `ui.commitsubrepos=True` is set.) subrepoutil.precommit() will abort on a dirty subrepo if the config option isn't set, but the hint recommends using --subrepos to commit. Since only the commit command currently supports that option, the error has to be raised here to omit the hint. Doing the check before asking about all of the hunks in the MQ test seems like an improvement on its own. There's probably an additional check on this path that can be removed.

"""Tool read primitive events from a pipe to produce a catapult trace.
Usage:
Terminal 1: $ catapipe.py /tmp/mypipe /tmp/trace.json
Terminal 2: $ HGCATAPULTSERVERPIPE=/tmp/mypipe hg root
<ctrl-c catapipe.py in Terminal 1>
$ catapult/tracing/bin/trace2html /tmp/trace.json # produce /tmp/trace.html
<open trace.html in your browser of choice; the WASD keys are very useful>
(catapult is located at https://github.com/catapult-project/catapult)
For now the event stream supports
START $SESSIONID ...
and
END $SESSIONID ...
events. Everything after the SESSIONID (which must not contain spaces)
is used as a label for the event. Events are timestamped as of when
they arrive in this process and are then used to produce catapult
traces that can be loaded in Chrome's about:tracing utility. It's
important that the event stream *into* this process stay simple,
because we have to emit it from the shell scripts produced by
run-tests.py.
Typically you'll want to place the path to the named pipe in the
HGCATAPULTSERVERPIPE environment variable, which both run-tests and hg
understand. To trace *only* run-tests, use HGTESTCATAPULTSERVERPIPE instead.
