logtoprocess: sends the canonical command name to the subprocess
One of the use-case of logtoprocess is to monitor command duration. With the
current code, we only get whatever command name the user typed (either
abbreviated or aliased).
This makes analytics on the collected data more difficult. Stores the
canonical command name in the request object. Pass the stored canonical name
in the `req.ui.log("commandfinish", ...)` call as keyword argument to not
break potential string formatting.
Pass the value as the environment variable named `LTP_COMMAND` to the called
script.

#require no-windows 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 __future__ import absolute_import > from mercurial import registrar > cmdtable = {} > command = registrar.command(cmdtable) > configtable = {} > configitem = registrar.configitem(configtable) > configitem('logtoprocess', 'foo', > default=None, > ) > @command(b'foobar', []) > def foo(ui, repo): > ui.log('foo', 'a message: %s\n', '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") > $TESTTMP/command.log > commandfinish=(echo 'logtoprocess commandfinish output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "\$MSG2"; > echo "\$MSG3"; > echo "canonical: \$OPT_CANONICAL_COMMAND") > $TESTTMP/commandfinish.log > foo=(echo 'logtoprocess foo output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "\$MSG2") > $TESTTMP/foo.log > EOF 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 fooba $ sleep 1 $ cat $TESTTMP/command.log | sort command fooba fooba logtoprocess command output: #if no-chg $ cat $TESTTMP/commandfinish.log | sort 0 canonical: foobar commandfinish fooba fooba exited 0 after * seconds (glob) logtoprocess commandfinish output: $ cat $TESTTMP/foo.log | sort a message: spam foo logtoprocess foo output: spam #endif 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" > $TESTTMP/uiblocked.log > [ui] > logblockedtimes=True > EOF $ hg log $ sleep 1 $ cat $TESTTMP/uiblocked.log uiblocked stdio [0-9]+.[0-9]* ms command [0-9]+.[0-9]* ms (re) Try to confirm that pager wait on logtoprocess: Add a script that wait on a file to appears for 5 seconds, if it sees it touch another file or die after 5 seconds. If the scripts is awaited by hg, the script will die after the timeout before we could touch the file and the resulting file will not exists. If not, we will touch the file and see it. $ cat > $TESTTMP/wait-output.sh << EOF > #!/bin/sh > for i in \`$TESTDIR/seq.py 50\`; do > if [ -f "$TESTTMP/wait-for-touched" ]; > then > touch "$TESTTMP/touched"; > break; > else > sleep 0.1; > fi > done > EOF $ chmod +x $TESTTMP/wait-output.sh $ cat >> $HGRCPATH << EOF > [extensions] > logtoprocess= > pager= > [logtoprocess] > commandfinish=$TESTTMP/wait-output.sh > EOF $ hg version -q --pager=always Mercurial Distributed SCM (version *) (glob) $ touch $TESTTMP/wait-for-touched $ sleep 0.2 $ test -f $TESTTMP/touched && echo "SUCCESS Pager is not waiting on ltp" || echo "FAIL Pager is waiting on ltp" SUCCESS Pager is not waiting on ltp
