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 $ cat >> $HGRCPATH << EOF > [extensions] > logtoprocess= > foocommand=$TESTTMP/foocommand.py > [logtoprocess] > command=echo 'logtoprocess command output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "\$MSG2" > commandfinish=echo 'logtoprocess commandfinish output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "\$MSG2"; > echo "\$MSG3" > foo=echo 'logtoprocess foo output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "\$OPT_BAR" > EOF Running a command triggers both a ui.log('command') and a ui.log('commandfinish') call. The foo command also uses ui.log. Use head to ensure we wait for all lines to be produced, and sort to avoid ordering issues between the various processes we spawn: $ hg foo | head -n 17 | 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 uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re)
