This extension lets you direct specific ui.log() information to shell commands, spawned in the background. This can be used to, say, capture timings, commandfailure tracebacks, etc., making the output available to other command-line tools.

ATTENTION: logtoprocess runs commands asynchronously. Be sure to append "| cat"
|
|
to hg commands, to wait for the output, if you want to test its output.
|
|
Otherwise the test will be flaky.
|
|
|
|
Test if logtoprocess correctly captures command-related log calls.
|
|
|
|
$ hg init
|
|
$ cat > $TESTTMP/foocommand.py << EOF
|
|
> from mercurial import cmdutil
|
|
> from time import sleep
|
|
> cmdtable = {}
|
|
> command = cmdutil.command(cmdtable)
|
|
> @command('foo', [])
|
|
> def foo(ui, repo):
|
|
> ui.log('foo', 'a message: %(bar)s\n', bar='spam')
|
|
> EOF
|

$ cp $HGRCPATH $HGRCPATH.bak

Running a command triggers both a ui.log('command') and a
|
|
ui.log('commandfinish') call. The foo command also uses ui.log.
|
|
|
|
Use sort to avoid ordering issues between the various processes we spawn:
|
|
$ hg foo | cat | sort
|
|
|
|
|
|
|
|
0
|
|
a message: spam
|
|
command
|
|
commandfinish
|
|
foo
|
|
foo
|
|
foo
|
|
foo
|
|
foo exited 0 after * seconds (glob)
|
|
logtoprocess command output:
|
|
logtoprocess commandfinish output:
|
|
logtoprocess foo output:
|
|
spam
|
|
|
|
Confirm that logging blocked time catches stdio properly:
|
|
$ cp $HGRCPATH.bak $HGRCPATH
|
|
$ cat >> $HGRCPATH << EOF
|
|
> [extensions]
|
|
> logtoprocess=
|
|
> pager=
|
|
> [logtoprocess]
|
|
> uiblocked=echo "\$EVENT stdio \$OPT_STDIO_BLOCKED ms command \$OPT_COMMAND_DURATION ms"
|
|
> [ui]
|
|
> logblockedtimes=True
|
|
> EOF
|
|
|
|
$ hg log | cat
|
|
uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re)
