narrow: allow repo.narrowmatch(match) to include exact matches from "match" Differential Revision: https://phab.mercurial-scm.org/D4900

narrow: filter files by narrowspec in ctx.matches() This has no effect yet because 1) for committed changes, ctx.matches() just calls ctx.walk(), which we updated in the previous patch, and 2) for the working copy, the filtering is also done in the overridden dirstate.walk() in narrowdirstate. Differential Revision: https://phab.mercurial-scm.org/D4899

narrow: only walk files within narrowspec also for committed revisions Narrow has been walking only paths matching the narrowspec when walking the working copy. We have not done the same filtering when walking committed revisions (e.g. "hg files -r "), which seems a little odd. Let's make it consistent. Differential Revision: https://phab.mercurial-scm.org/D4898

status: intersect matcher with narrow matcher instead of filtering afterwards I seem to have done a very naive move of the code from the narrow extension into core in e411774a2e0f (narrow: move status-filtering to core and to ctx, 2018-08-02). It seems obvious that a better way is to intersect the matchers. Note that this means that when requesting status for the working directory in a narrow repo, we now pass the narrow matcher (possibly intersected with a user-provided matcher) into _buildstatus() and then into dirstate.status() and dirstate.walk(), which will the intersect it again with the narrow matcher. That's functionally fine, but wasteful. I hope to later remove the dirstate wrapping that adds the second layer of matcher intersection. Differential Revision: https://phab.mercurial-scm.org/D4897

localrepo: allow narrowmatch() to accept matcher to intersect with It's pretty common that we need to intersect a matcher we already have (usually from the user) with the narrow matcher. Let's make repo.narrowmatch() take an optional matcher to intersect with. Differential Revision: https://phab.mercurial-scm.org/D4896

obsolete: fix ValueError when stored note contains ':' char (issue5783) The newer version of `amend -n 'Some some'` accepts containing ':' char. The information contained in this note 'Testing::Obstore' gives ValueError, because we are trying to store more than 2 values in key and value.

narrow: update TODO.rst now that we share format with sparse The narrowspec format was unified with the sparse format in f64ebe7d2259 (narrowspec: use sparse.parseconfig() to parse narrowspec file (BC), 2018-08-03). Differential Revision: https://phab.mercurial-scm.org/D4904

narrow: update TODO.rst now that we filter status in ctx The comment referred to was addressed in e411774a2e0f (narrow: move status-filtering to core and to ctx, 2018-08-02). I also think 84092edd5c88 (narrow: drop unnecessary overrides of patch, 2018-09-28) suggests that it was the right thing to do. Differential Revision: https://phab.mercurial-scm.org/D4903

narrow: update TODO.rst now that the narrowspec is in .hg/store We no longer have the unfortunate wrappostshare() and unsharenarrowspec() since 576eef1ab43d (narrow: move .hg/narrowspec to .hg/store/narrowspec (BC), 2018-08-02). Differential Revision: https://phab.mercurial-scm.org/D4902

py3: add 8 new passing tests to whitelist found by buildbot We are getting close! Differential Revision: https://phab.mercurial-scm.org/D4893

py3: use '%f' for floats instead of '%s' I remember Yuya saying we need to use bytestr() or '%r' because '%s' was clever. Not sure it applies to this or not. Differential Revision: https://phab.mercurial-scm.org/D4894

narrow: move adding of narrow server capabilities to core We use the experimental.narrow config option introduced in one of the previous patch and move the functionality of adding narrow server capabilities to core. Differential Revision: https://phab.mercurial-scm.org/D4891

wireprotoserver: move narrow capabilities to wireprototypes.py This is done because wireprotoserver import wireprotov1server, so you cannot import wireprotoserver in wireprotov1server to use the capabilities constants. Differential Revision: https://phab.mercurial-scm.org/D4890

narrow: introduce a config option to check if narrow is enabled or not This patch introduces a new config option experimental.narrow which is set to False by default and set to True by the narrow extension. While moving narrow related logic into core, we need to know at places whether narrow extension is enabled or not. Checking the list of extension enabled is one solution but once narrow is inbuilt, we will definitely want a config option to check whether narrow is turned on or not. So this patch introduces a config option, which will evolve to the main point to turn narrow capability on and off once all the narrow is in core.

narrow: start returning bundle2 from widen_bundle() Differential Revision: https://phab.mercurial-scm.org/D4838

narrow: the first version of narrow_widen wireprotocol command This patch introduces a wireprotocol command narrow_widen() which will be used to widen a narrow copy using `hg tracked` command provided by narrow extension. The wireprotocol command takes the old and new includes and excludes, common heads, changegroup version, known revs, and a boolean ellipses and generates a bundle2 of the required data and send it. The clients receives the bundle2 and applies that. A bundle2 instead of changegroup because in future we might want to add more things to send while widening. Thanks for martinvonz for the suggestion. I am not sure whether we need changegroup version as an argument to the command as I *think* narrow needs changegroup3 already. The tests shows that we don't exchange phase data now while widening which is nice. Also we don't check for pushkeys, rbc-cache, bookmarks etc. This does not support ellipses cases for now but will be supported in future patches. Since we send bundle2, it won't be hard to plug the ellipses logic in here. The existing code for widening a non-ellipses case is also dropped in this patch.

remotenames: abort if literal revset pattern matches nothing This is the convention of the other namespace revsets such as tag(). Let's make the remote variants do the same.

remotenames: remove unneeded sorted() from revset implementation The order is constrained by the subset.

remotenames: don't call a set of nodes as "revs"

remotenames: use util.always instead of handcrafted lambda

remotenames: inline _parseargs() into _revsetutil() The _parseargs() function gets quite simple, and the 0/1 loop can be rewritten as "if".

repo: create changectx in a single place in localrepo.__getitem__ Differential Revision: https://phab.mercurial-scm.org/D4885

repo: remove the last few "pass" statements in localrepo.__getitem__ In case of IndexError or LookupError, we used "pass" statements and fell through to the end of localrepo.__getitem__. I find the pass statements easy to miss. Consistently raising and catching exceptions seems easier to follow. Oh -- and I didn't plan this before I wrote the above -- that probably also lets us reuse the "return context.changectx(self, rev, node)" in a later patch.
