largefiles: omit redundant isstandin() before splitstandin()
There are many isstandin() invocations before splitstandin().
The former examines whether specified path starts with ".hglf/". The
latter returns after ".hglf/" of specified path if it starts with that
prefix, or returns None otherwise.
Therefore, value returned by splitstandin() can be used for
replacement of preceding isstandin(), and this replacement can omit
redundant string comparison after isstandin().
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 cmdutil
> from time import sleep
> cmdtable = {}
> command = cmdutil.command(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)
