fix: allow fixer tools to return metadata in addition to the file content
With this change, fixer tools can be configured to output a JSON object that
will be parsed and passed to hooks that can be used to print summaries of what
code was formatted or perform other post-fixing work.
The motivation for this change is to allow parallel executions of a
"meta-formatter" tool to report back statistics, which are then aggregated and
processed after all formatting has completed. Providing an extensible mechanism
inside fix.py is far simpler, and more portable, than trying to make a tool
like this communicate through some other channel.

#require no-windows 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 __future__ import absolute_import > 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. $ cat >> fakepager.py <<EOF > import sys > printed = False > for line in sys.stdin: > sys.stdout.write(line) > printed = True > if not printed: > sys.stdout.write('paged empty output!\n') > EOF $ cat > $TESTTMP/wait-output.sh << EOF > #!/bin/sh > for i in \`$TESTDIR/seq.py 50\`; do > if [ -f "$TESTTMP/wait-for-touched" ]; > then > touch "$TESTTMP/touched"; > break; > else > sleep 0.1; > fi > done > EOF $ chmod +x $TESTTMP/wait-output.sh $ cat >> $HGRCPATH << EOF > [extensions] > logtoprocess= > pager= > [pager] > pager = "$PYTHON" $TESTTMP/fakepager.py > [logtoprocess] > commandfinish=$TESTTMP/wait-output.sh > EOF $ hg version -q --pager=always Mercurial Distributed SCM (version *) (glob) $ touch $TESTTMP/wait-for-touched $ sleep 0.2 $ test -f $TESTTMP/touched && echo "SUCCESS Pager is not waiting on ltp" || echo "FAIL Pager is waiting on ltp" SUCCESS Pager is not waiting on ltp
