phase: add an archived phase
This phase allows for hidden changesets in the "user space". It differs from
the "internal" phase which is intended for internal by-product only. There
have been discussions at the 4.8 sprint to use such phase to speedup cleanup
after history rewriting operation.
Shipping it in the same release as the 'internal-phase' groups the associated
`requires` entry. The important bit is to have support for this phase in the
earliest version of mercurial possible. Adding the UI to manipulate this new
phase later seems fine.
The current plan for archived usage and user interface are as follow. On a
repository with internal-phase on and evolution off:
* history rewriting command set rewritten changeset in the archived phase.
(This mean updating the cleanupnodes method).
* keep `hg unbundle .hg/strip-backup/X.hg` as a way to restore changeset for
now
(backup bundle need to contains phase data)
* [maybe] add a `hg strip --soft` advance flag
(a light way to expose the feature without getting in the way of a better
UI)
Mercurial 4.8 freeze is too close to get the above in by then.
We don't introduce a new repository `requirement` as we reuse the one
introduced with the 'archived' phase during the 4.8 cycle.

#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('logtoprocess', 'foo', > default=None, > ) > @command(b'foobar', []) > def foo(ui, repo): > ui.log('foo', 'a message: %s\n', '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") > $TESTTMP/command.log > commandfinish=(echo 'logtoprocess commandfinish output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "\$MSG2"; > echo "\$MSG3"; > echo "canonical: \$OPT_CANONICAL_COMMAND") > $TESTTMP/commandfinish.log > foo=(echo 'logtoprocess foo output:'; > echo "\$EVENT"; > echo "\$MSG1"; > echo "\$MSG2") > $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 fooba logtoprocess command output: #if no-chg $ cat $TESTTMP/commandfinish.log | sort 0 canonical: foobar commandfinish fooba fooba exited 0 after * seconds (glob) logtoprocess commandfinish output: $ cat $TESTTMP/foo.log | sort a message: spam foo logtoprocess foo output: spam #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 > $TESTTMP/wait-output.sh << EOF > #!/bin/sh > for i in \`$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 >> $HGRCPATH << EOF > [extensions] > logtoprocess= > pager= > [logtoprocess] > commandfinish=$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
