streamclone: new server config and some API changes for narrow stream clones This patch introduces a new server config `experimental.server.stream-narrow-clones` which if set to True will advertise that the server supports narrow stream clones. This patch also pass on the includes and excludes from getbundle command to streamclone generation code. There is a test added to show that the includepats and excludepats are correctly passed. Upcoming patches will implement storage layer filtering for streamclones and then we can remove the temporary error and plug in the whole logic together to make narrow stream clones working.

narrow: only send the narrowspecs back if ACL in play I am unable to think why we need to send narrowspecs back from the server. The current state adds a 'narrow:spec' part to each changegroup which is generated when narrow extension is enabled. So we are sending narrowspecs on pull also. There is a problem with sending the narrowspecs the way we are doing it right now. We add include and exclude as parameter of the 'narrow:spec' bundle2 part. The the len of include or exclude string increase 255 which is obvious while working on large repos, bundle2 generation code breaks. For more on that refer issue5952 on bugzilla. I was thinking why we need to send the narrowspecs back, and deleted the 'narrow:spec' bundle2 part generation code and found that only narrow-acl test has some failure. With this patch, we will only send the 'narrow:spec' bundle2 part if ACL is enabled because the original narrowspecs in those cases can be a subset of narrowspecs user requested. There are phase related output change in couple of tests. The output change shows that we are now dealing in public phases completely. So maybe sending the narrow:spec bundle2 part was preventing phases being exchanged or phase bundle2 data being applied. Differential Revision: https://phab.mercurial-scm.org/D4931

zsh_completion: add -l/--list flag for hg bookmarks completion Flags in parentheses are mutually exclusive. Logic is taken from commands.py: selactions = [k for k in ['delete', 'rename', 'list'] if opts.get(k)] if len(selactions) > 1: raise error.Abort(_('--%s and --%s are incompatible') % tuple(selactions[:2])) ... if rev and action in {'delete', 'rename', 'list'}: raise error.Abort(_("--rev is incompatible with --%s") % action) if inactive and action in {'delete', 'list'}: raise error.Abort(_("--inactive is incompatible with --%s") % action) Differential Revision: https://phab.mercurial-scm.org/D5142

zsh_completion: use $_hg_remote_opts after it is defined Before this patch, zsh wouldn't complete --ssh, --remotecmd or --insecure for hg clone. While at it, replace --uncompressed by --stream. Differential Revision: https://phab.mercurial-scm.org/D5140

exchange: support declaring pull depth Upcoming commits will teach exchangev2 how to perform a shallow clone. This commit teaches hg.clone(), exchange.pull(), and exchange.pulloperation to recognize a request for a shallow clone by having the caller specify a numeric depth of the maximum number of ancestor changesets to fetch. There are certainly other ways we could control shallow-ness. But this one is simple to implement and is also how the narrow extension controls things. So it seems to make sense to start here.
