upgrade: allow upgrade to repository using sidedata
Repository can now be migrated to support sidedata. More requirements and
migration will be needed to actual side-data usage. This is a step in that
direction.
To test the feature, we leverage the test extension. It make sure the `update`
part of the side-data migration actually works.

============================================================================================ Test cases where there are race condition between two clients pushing to the same repository ============================================================================================ This file tests cases where two clients push to a server at the same time. The "raced" client is done preparing it push bundle when the "racing" client perform its push. The "raced" client starts its actual push after the "racing" client push is fully complete. A set of extension and shell functions ensures this scheduling. $ cat >> delaypush.py << EOF > """small extension orchestrate push race > > Client with the extensions will create a file when ready and get stuck until > a file is created.""" > > import errno > import os > import time > > from mercurial import ( > exchange, > extensions, > registrar, > ) > > configtable = {} > configitem = registrar.configitem(configtable) > > configitem(b'delaypush', b'ready-path', > default=None, > ) > configitem(b'delaypush', b'release-path', > default=None, > ) > > def delaypush(orig, pushop): > # notify we are done preparing > ui = pushop.repo.ui > readypath = ui.config(b'delaypush', b'ready-path') > if readypath is not None: > with open(readypath, 'w') as r: > r.write('foo') > ui.status(b'wrote ready: %s\n' % readypath) > # now wait for the other process to be done > watchpath = ui.config(b'delaypush', b'release-path') > if watchpath is not None: > ui.status(b'waiting on: %s\n' % watchpath) > limit = 100 > while 0 < limit and not os.path.exists(watchpath): > limit -= 1 > time.sleep(0.1) > if limit <= 0: > ui.warn(b'exiting without watchfile: %s' % watchpath) > else: > # delete the file at the end of the push > def delete(): > try: > os.unlink(watchpath) > except OSError as exc: > if exc.errno != errno.ENOENT: > raise > ui.atexit(delete) > return orig(pushop) > > def uisetup(ui): > extensions.wrapfunction(exchange, b'_pushbundle2', delaypush) > EOF $ waiton () { > # wait for a file to be created (then delete it) > count=100 > while [ ! -f $1 ] ; > do > sleep 0.1; > count=`expr $count -
