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 time import sleep

  > 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 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)
