Profiling of HTTP requests works

  $ $prof --config profiling.format=text --config profiling.output=../profile.log serve -d -p $HGPORT --pid-file ../hg.pid -A ../access.log

  $ cat ../hg.pid >> $DAEMON_PIDS

A single profile is logged because file logging doesn't append

  $ grep CallCount ../profile.log | wc -l

Install an extension that can sleep and guarantee a profiler has time to run

  $ cat >> sleepext.py << EOF

  > import time

  > from mercurial import registrar, commands

  > cmdtable = {}

  > command = registrar.command(cmdtable)

  > @command('sleep', [], 'hg sleep')

  > def sleep(ui, *args, **kwargs):

  >     time.sleep(0.1)

  > EOF

  $ cat >> $HGRCPATH << EOF

  > [extensions]

  > sleep = `pwd`/sleepext.py

statistical profiler works

  $ grep Sample ../out

Various statprof formatters work

  $ hg --profile --config profiling.statformat=byline sleep 2>../out

  $ head -n 1 ../out

    %   cumulative      self          

  $ grep Sample ../out

  Sample count: \d+ (re)

  $ hg --profile --config profiling.statformat=bymethod sleep 2>../out

  $ head -n 1 ../out

  $ grep Sample ../out

  $ hg --profile --config profiling.statformat=hotpath sleep 2>../out

  $ grep Sample ../out

statprof can be used as a standalone module

  $ $PYTHON -m mercurial.statprof hotpath

  must specify --file to load
