phases: stop using `repo.set` in `remotephasessummary`
The `repository.set` create changectx on the fly, an expensive operation. Using
`repo.revs` and a direct rev-num → node-id translation will be significantly
faster.
This is especially true as we prepare ourself to no longer do the rev-num →
node-id transalation there.
The speedup is a bit lost in the overall noisyness of the slow phase discovery algorithm, but it save a small amount of time in my benchmark.

#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 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 waits on a file to appear. If the script is awaited by hg, the script will die after the timeout before we could touch the file and the resulting file will not exist. 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 > $TESTTMP/wait-output.sh << EOF > #!/bin/sh > set -eu > "$RUNTESTDIR/testlib/wait-on-file" 10 "$TESTTMP/wait-for-touched" > touch "$TESTTMP/touched" > 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 $ "$RUNTESTDIR/testlib/wait-on-file" 5 "$TESTTMP/touched" $ 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
