py3: split check of pygments-using files from the rest of the tree If we don't do this, people without pygments installed in their Python 3 environment silently stop checking test-check-py3-compat, which isn't really what we wanted. This preserves stability of the test output while still letting anyone with a recent-enough Python 3 run the majority of the Python 3 compat checking test.

version: change "place" field of extension to "bundled" flag The name "place" sounds odd. We can simply expose raw boolean values instead of switching external/internal literals.

extensions: use ismoduleinternal() thoroughly "ships-with-hg-core" would be long enough to typo.

lock: show more detail for new-style locks in lock waiting message (issue4752) Improve the lock waiting warning message by explicitly saying that a host and process are holding the lock. This nudges confused new users in the direction of investigating the other process instead of removing the lock.

formatter: add context manager interface for convenience And port "hg files" to test it. As you can see, extra indent is necessary to port to this API. I don't think we should switch every fm.formatter() call to "with" statement.

histedit: remove now unused 'constraints' related code Now that the one action that need different logic handle that using inheritance and overriding, we can remove that code.

histedt: use inheritance to override the constraints in 'base' All actions but one actually have the same constraints when it comes to validate the 'action.node' value. So we actually just add this code to a method that can be overwritten in the one action where it matters. The now unused 'contraints' related enum and class attribute will be cleaned up in the next changeset.

histedit: move constraint verification to the 'action.verify' method Action has a method dedicated to verifying its validity. So we move code related to constrains into that method. This requires a bit more context to the 'verify' method in the same fashion we were passing the 'prev' argument. This is an extra step before we can simplify the constraint handling code further.

histedit: directly use node in 'verifyactions' It does not seem useful to convert to hex: it is an extra step and they are longer strings. So we stick to node for the logic. We only convert to short hex for error when needed. As a nice side effect this remove the explicit constant usage in'[12:]'. This will also help moving the code around later as we just have to access action.node.

histedit: temporarily shorten name of 'constraints' variable An upcoming changeset will make the line where this variable is used slightly too long. Other later changesets will clean that up further and makes the variable unnecessary, so this is only temporary and it does seems useful to put anything more complicate in place.

histedit: drop the 'nodetoverify' local variable We can just use 'action.node'.

histedit: make 'constraints' a class attribute instead of a method There does not seem to be a reason for this to be a method. So we initialise the class attribute once and for all at creation time and drop the instance method.

histedit: drop the 'nodetoverify' method That method is just returning self.node and is never overridden. We just use the attribute directly instead and get rid of the method. This is the beginning of series to simplify and unify verification of constraints for actions.

test-gpg: start gpg-agent by gpg-connect-agent only if GnuPG v2.1+ detected Danek Duvall found that gpg-connect-agent of GnuPG 2.0 never starts gpg-agent daemon. The 2.1 way is documented as "gpg-coonect-agent /bye" [1], which appears to be different from the 2.0 way [2]. [1]: https://www.gnupg.org/documentation/manuals/gnupg/Invoking-GPG_002dAGENT.html [2]: https://www.gnupg.org/documentation/manuals/gnupg-2.0/Invoking-GPG_002dAGENT.html Since "gpg-agent --daemon" of GnuPG 2.1 never prints environment variables, "eval $(gpg-agent --daemon)" would be valid only for GnuPG < 2.1, and we'll need a different workaround for 2.0. I have no 2.0 environment, I won't implement it.

rebase: properly calculate total commits to rebase (issue5347) Before this, predecessor commits were being included in the count

mpatch: add setup_mpatch_cffi.py This file got dropped when the corresponding setup.py changes were made.

journal: rename on disk files to 'namejournal' The 'journal' naming is already used by the transaction journal. Having an unrelated group of file with such a close naming is confusing and error prone. We rename the file used by the 'journal' extension to use 'namejournal' as the extension track the location of various 'names'.

tests: guard demandimport segment of test-extension.t

tests: skip demandimport if disabled demandimport and setuptools and decorator (from ironpython) and pygments leads to lots of fail. If demandimport is disabled we should skip testing it...

hghave: add demandimport checking

hghave: make bzr checks stricter My bzr does not have bzrlib.revisionspec.RevisionSpec, and thus tests were failing because convert refused to believe in bzr, but hghave without this change thought it was available.

help: document wire protocol commands

help: document wire protocol "handshake" protocol There isn't a formal handshake protocol in the wire protocol. But clients almost certainly need to perform particular actions before they can communicate with a server optimally. So document what that is so people understand what's going on at connection establishment time.

help: document wire protocol capabilities All capabilities from the history of the project are now documented.

help: document wire protocol transport protocols The HTTP and SSH transport protocols are documented. This includes how commands and arguments are serialized as well as response types.

help: internals topic for wire protocol The Mercurial wire protocol is under-documented. This includes a lack of source docstrings and comments as well as pages on the official wiki. This patch adds the beginnings of "internals" documentation on the wire protocol. The documentation should have nearly complete coverage on the lower-level parts of the protocol, such as the different transport mechanims, how commands and arguments are sent, capabilities, and, of course, the commands themselves. As part of writing this documentation, I discovered a number of deficiencies in the protocol and bugs in the implementation. I've started sending patches for some of the issues. I hope to send a lot more. This patch starts with the scaffolding for a new internals page.

grep: add formatter support Several fields are renamed to be consistent with the annotate command, which doesn't mean the last call for the name unification [1]. Actually, I'd rather rename line_number to linenumber, linenum, lineno or line, but I want to port the grep command to formatter first. [1]: https://www.mercurial-scm.org/wiki/GenericTemplatingPlan#Dictionary I don't have any better name for the list of matched/unmatched texts, so they are just called as "texts".

grep: build list of all columns regardless of display options These columns should always be available in JSON or template outputs. The "change" column is excluded because it has no useful data unless --all is specified.

grep: build list of columns without "grep." label prefix Prepares for formatter support. We need field names without "grep.".

grep: factor out function that prints matched line with labels Prepares for formatter support.
