py3: listify the return value of filter() filter() on Python 3 returns a filter object. Differential Revision: https://phab.mercurial-scm.org/D2515

sshpeer: factor out code for creating peers from pipes An upcoming commit will want to instantiate an SSH peer via an alternate mechanism that doesn't require running a new `ssh` command. To facilitate that, we extract the code for creating a peer from pipes to its own function. Differential Revision: https://phab.mercurial-scm.org/D2391

py3: add b'' prefixes in tests/test-rollback.t This makes the test run succesfully on Python 3. There is just a b'' prefix extra in the output. # skip-blame because we added just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D2510

py3: add b'' prefix in tests/test-revlog-v2.t After this, the test works on Python 3. There is some extra return value by open().write() I think which needs to be handled. # skip-blame because just b'' prefix Differential Revision: https://phab.mercurial-scm.org/D2509

py3: add b'' prefixes in tests/test-revlog.t # skip-blame because just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D2508

py3: make sure we open the file in bytes mode This makes the test pass on Python 3. Differential Revision: https://phab.mercurial-scm.org/D2507

py3: add b'' prefixes in tests/test-revlog-ancestry.py # skip-blame because just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D2506

py3: backout changeset 56635c506608 which wrongly added couple of b'' I am not sure what I was thinking when I added that but while fixing rebase tests, I revisited the file and found that I did wrong. I am sorry for this. Differential Revision: https://phab.mercurial-scm.org/D2504

narrow: drop safehasattr() checks for always-present repo.narrowmatch I've added checks for repo.narrowmatch().always() in order to restore some of the fast paths for non-narrow repos. Differential Revision: https://phab.mercurial-scm.org/D2495

narrow: move narrowmatch-related methods to localrepo This patch makes it so localrepo.narrowmatch() and a few more are always available, which will let us simplify the use sites a bit. narrowmatch() will return an always-matcher in non-narrow repos (just like it did when it lived in the narrow extension). Differential Revision: https://phab.mercurial-scm.org/D2494

narrow: remove dependency from narrowspec module to hg module Differential Revision: https://phab.mercurial-scm.org/D2493

narrow: reduce depedence on narrowspec.save() I think narrowspec should be a simple, low-level module and not depend on the hg module. This prepares for moving that dependency out of narrowspec. Differential Revision: https://phab.mercurial-scm.org/D2492

narrow: always wrap repo It's simpler to always wrap the repo. This prepares for moving narrowrepo.narrowmatch() onto localrepo by showing that it's now safe to always wrap the repo (and thus always define narrowmatch() etc.). Note that since narrowmatch() returns an always-matcher (rather than None) in non-narrow repos, this may mean a performance hit when the narrow extension is enabled because it adds a no-op filtering step in various places against the always-matcher. I'll restore some of that soon. Differential Revision: https://phab.mercurial-scm.org/D2491

narrow: consider both local and remote matchers in narrowchangegroup The existing code that picked one or the other seemed very suspicious. This patch makes us intersect the local matcher with the matcher from the remote, which seems better. It fixes one test case and makes another one that used to crash no longer crash, but instead silently succeed with a push that's lossy, so that remains to be fixed. The real reason for doing this now is that I'm going to move narrowrepo.narrowmatch() onto localrepo and then it will always be defined, which would otherwise break this code. Differential Revision: https://phab.mercurial-scm.org/D2490

narrow: move checking for narrow requirement into _narrowmatch() We want to move narrowmatch() and others into core, so we need to get rid of the dependence on the "narrow_opts" from the closure in narrowrepo.wraprepo(). We can simply check if the narrow requirement is set. I think that seems like an improvement regardless of moving narrowmatch(). Differential Revision: https://phab.mercurial-scm.org/D2489

narrow: move changegroup.supportedoutgoingversions() override to core Also document why we need cg3 or higher. Differential Revision: https://phab.mercurial-scm.org/D2488
