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

    51 

    52   $ cat >> sleepext.py << EOF

    53   > import time

    54   > from mercurial import cmdutil, commands

    55   > cmdtable = {}

    56   > command = cmdutil.command(cmdtable)

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

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

    59   >     time.sleep(0.1)

    60   > EOF

    61 

    62   $ cat >> $HGRCPATH << EOF

    63   > [extensions]

    64   > sleep = `pwd`/sleepext.py

    65   > EOF

    67 statistical profiler works

    68 

    69   $ HGPROF=stat hg --profile sleep 2>../out

    70   $ grep Sample ../out

    71   Sample count: \d+ (re)

    72 

    73 Various statprof formatters work

    74 

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

    76   $ head -n 1 ../out

    77     %   cumulative      self          

    78   $ grep Sample ../out

    79   Sample count: \d+ (re)

    80 

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

    82   $ head -n 1 ../out

    83     %   cumulative      self          

    84   $ grep Sample ../out

    85   Sample count: \d+ (re)

    86 

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

    88   $ grep Sample ../out

    89   Sample count: \d+ (re)

    90 

    91   $ HGPROF=stat hg --profile --config profiling.statformat=json sleep 2>../out

    92   $ cat ../out

    93   \[\[\d+.* (re)
