The wirepeer class provides concrete implementations of peer interface methods for calling wire protocol commands. It makes sense for this class to inherit from the peer abstract base class. So we change that. Since httppeer and sshpeer have already been converted to the new interface, peerrepository is no longer adding any value. So it has been removed. httppeer and sshpeer have been updated to reflect the loss of peerrepository and the inheritance of the abstract base class in wirepeer. The code changes in wirepeer are reordering of methods to group by interface. Some Python code in tests was updated to reflect changed APIs. .. api:: peer.peerrepository has been removed. Use repository.peer abstract base class to represent a peer repository. Differential Revision: https://phab.mercurial-scm.org/D338

We need the same @property conversion of ui like we did for localpeer. We renamed _capabilities() to capabilities() to satisfy the new naming requirement. However, since we're inheriting from wireproto.wirepeer which inherits from peer.peerrepository and provides its own code accessing _capabilities(), we need to keep the old alias around. This wonkiness will disappear once wirepeer is cleaned up in subsequent commits. We also implement methods for basepeer that are identical to the defaults in peer.peerrepository in preparation for the removal of peerrepository.

We now have a formal abstract base class for peers. Let's transition the peer classes in localrepo to it. As part of the transition, we reorder methods so they are grouped by interface and match the order they are defined in the interface. We also had to change self.ui from an instance attribute to a property to satisfy the @abstractproperty requirement. As part of this change, we uncover the first "bug" as part of enforcing interfaces: stream_out() wasn't implemented on localpeer! This isn't technically a bug since the repo isn't advertising the stream capability, so clients shouldn't be attempting to call it. But I don't think there's a good reason why this is the case. We implement a dummy method to satisfy the interface requriements. We can make localpeer instances streamable as a future enhancement. # no-check-commit Differential Revision: https://phab.mercurial-scm.org/D335

These methods are part of the peer interface, are generic, and can be implemented in terms of other members of the peer interface. So we implement them on the peer base class as a convenience. The implementation is essentially copied from peer.py. The code in peer.py will eventually be deleted. Differential Revision: https://phab.mercurial-scm.org/D334

There are a well-defined set of commands constituting the wire protocol. Interaction with these and methods for calling them in batches are exposed via methods on peer instances. Let's formalize support for these features in abstract classes. The command parts come from the existing wireproto.wirepeer class. The batch methods come from peer.peerrepository. Ample documentation has been added as part of defining the interfaces. # no-check-commit Differential Revision: https://phab.mercurial-scm.org/D333

There are various interfaces for interacting with repositories and peers. They form a contract for how one should interact with a repo or peer object. The contracts today aren't very well-defined or enforced. There have been several bugs over the years where peers or repo types have forgotten to implement certain methods. In addition, the inheritance of some classes is wonky. For example, localrepository doesn't inherit from an interface and the god-object nature of that class means the repository interface isn't well-defined. Other repository types inherit from localrepository then stub out methods that don't make sense (e.g. statichttprepository re-defining locking methods to fail fast). Not having well-defined interfaces makes implementing alternate storage backends, wire protocol transports, and repository types difficult because it isn't clear what exactly needs to be implemented. This patch starts the process of attempting to establish more order to the type system around repositories and peers. Our first patch starts with a problem space that already has a partial solution: peers. The peer.peerrepository class already somewhat defines a peer interface. But it is missing a few things and the total interface isn't well-defined because it is combined with wireproto.wirepeer. Our newly-established basepeer class uses the abc module to declare an abstract base class with the properties and methods that a generic peer must implement. We create a new class that inherits from it. This class will hold our other future abstract base classes / interfaces so we can expose a unified base class/interface. We don't yet use the new interface because subsequent additions will break existing code without some refactoring first. A new module (repository.py) was created to hold the interfaces. I could have put things in peer.py. However, I have plans to eventually add interfaces to define repository and storage types. These almost certainly require a new module. And I figured having all the interfaces live in one module makes sense. So I created repository.py to be that future home. Differential Revision: https://phab.mercurial-scm.org/D332

279cd80059d4 made `util.nogc` a no-op. It was to optimize PyPy. But it slows down CPython if many objects (like 300k+) are created. For example, running `hg log -r .` without extensions in `hg-committed` with 14k+ obsmarkers have the following times: before | after hg | chg | hg | chg ----------------------------- 1.262 | 0.860 | 1.077 | 0.619 (seconds, best of 20 runs) Therefore let's re-enable nogc for CPython.

We have at least three types with a close() and a release() method where the close() method is supposed to be called on success and the release() method is supposed to be called last, whether successful or not. Two of them (transaction and dirstateguard) already have identical implementations of __enter__ and __exit__.

Previously `hg phabsend` was imitating `hg email` and won't mutate changesets. That works fine with reviewer-push workflow, reviewers run `phabread`, `import`. However, it does not work well with author-push workflow. Namely, the author needs to run extra commands to get the right commit message, and remove the local tag after push. This patch solves those issues by adding the `--amend` option, so local changesets will have the right commit message, and tags become unnecessary. Test Plan: Given the following DAG: o 17 o 16 | o 15 | @ 14 |/ o 13 o 12 Run `hg phabsend '(13::)-17' --amend`, check the new DAG looks like: o 21 | o 20 | @ 19 |/ o 18 | o 17 | x 16 | x 13 |/ o 12 And commit messages are updated to contain the `Differential Revision` lines. Use `phabread` to make sure Phabricator has the amended node recorded. Also check `phabsend .` followed by a `phabsend . --amend`, the commit message will be updated and the tag will be removed.

"defineparents" is the core algorithm of rebase. The old code has too many tech debts (like outdated comments, confusing assertions, etc) and is very error-prone to be improved. This patch rewrites "defineparents" to make the code easier to reason about, and solve a bunch of issues, including: - Assertion error: no base found (demonstrated by D212, issue5578) - Asymmetric result (demonstrated by D211, "F with one parent") - Wrong new parent (demonstrated by D262, "C':A'A'") - "revlog index out of range" (demonstrated by D262, issue5630) - "nothing to merge" (demonstrated by D262) As a side effect, merge base decision has been made more solid - rebase now prints out explicitly what could go wrong when it cannot find a unique suitable merge base. .. fix:: Issue 5578, Issue 5630 Core rebase algorithm has been rewritten to be more robust.

morestatus extension in fbext use to show more context about the state of the repo like the repository is in a unfinished merge state, or a rebase is going on, or histedit is going on, listing the files which need to be resolved and also suggesting ways to handle the situation. This patch moves the extension directly to core by plugging it into the --verbose flag of the status command. So now if you are in any unfinished state and you do hg status -v, it will show you details and help related to the state. The extension in fbext also shows context about unfinished update state which is not ported to core as that plug in hooks to update command which need to be tackled somewhat differently. The following configuration will turn the behaviour on by default [commands] status.verbose = 1 You can also skip considering some states like bisect as follows: [commands] status.skipstates=bisect This patch also adds test for the feature. .. feature:: ``hg status -v`` can now show unfinished state. For example, when in an unfinished rebase state, ``hg status -v`` might show:: # The repository is in an unfinished *rebase* state. # No unresolved merge conflicts. # To continue: hg rebase --continue # To abort: hg rebase --abort Differential Revision: https://phab.mercurial-scm.org/D219

Peer types are supposed to conform to a formal interface defined by peer.peerrepository and wireproto.wirepeer. Every "public" attribute on *peer types makes it harder to understand what attributes are part of the interface and what are instance specific. This commit converts a number of "public" instance attributes and methods on sshpeer to internal so they can't be confused to be part of the peer API. The URL-related instance attributes were introduced in 876333a295ff in 2005. AFAICT most of them aren't used and could potentially be removed. But I kept them around anyway. I also reorded some code to make things slightly easier to read. .. api:: Rename attributes on sshpeer to reflect peer API Differential Revision: https://phab.mercurial-scm.org/D331

The last use of this API was removed in b6e71f8af5b8 in 2016. While not formally deprecated, as of the last commit the code is no longer explicitly tested. I think the new API has existed long enough for people to transition to it. I also have plans to more formalize the peer API and removing batch() makes that work easier. I'm not convinced the current client-side API around batching is great. But it's the best we have at the moment. .. api:: remove peer.batch() Replace with peer.iterbatch().
