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 mercurial import registrar

  > cmdtable = {}

  > command = registrar.command(cmdtable)

  > configtable = {}

  > configitem = registrar.configitem(configtable)

  > configitem(b'logtoprocess', b'foo',

  >     default=None,

  > )

  > @command(b'foobar', [])

  > def foo(ui, repo):

  >     ui.log(b'foo', b'a message: %s\n', b'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") > $TESTTMP/command.log

  > commandfinish=(echo 'logtoprocess commandfinish output:';

  >     echo "\$EVENT";

  >     echo "\$MSG1";

  >     echo "canonical: \$OPT_CANONICAL_COMMAND") > $TESTTMP/commandfinish.log

  > foo=(echo 'logtoprocess foo output:';

  >     echo "\$EVENT";

  >     echo "\$MSG1") > $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

  logtoprocess command output:

#if no-chg

  $ cat $TESTTMP/commandfinish.log | sort

  canonical: foobar

  commandfinish

  fooba exited 0 after * seconds (glob)

  logtoprocess commandfinish output:

  $ cat $TESTTMP/foo.log | sort

  a message: spam

  foo

  logtoprocess foo output:

#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.
