revset: add public function to create matcher from evaluatable tree "hg debugrevspec" will use it to evaluate unoptimized tree.

revset: make analyze() a separate step from optimize() This will allow us to evaluate unoptimized tree and compare the result with optimized one. The private _analyze() function isn't renamed since I'll add more parameters to it.

revset: extract tree transformation from optimize() This patch separates the simple tree transformation from the optimization step, which is called as _analyze() since I'll extend this function to infer ordering flags. I want to avoid making _optimize() more complicated. This will also allow us to evaluate unoptimized tree.

hghave: fix has_bzr() to not try to import RevisionSpec as module Since RevisionSpec isn't a module, "import bzrlib.revisionspec.RevisionSpec" would always raise ImportError.

update: label bookmark name in message We label bookmark name as such in various messages. This will help them to standout (or at least give the user the option to make them stand out). We use a distinct label for the 'active' bookmark, this can help users to catch bookmark operation affecting their working copy.

discovery: explicitly check for None in outgoing init f09d0004481c introduced default params for discovery.outgoing(), but it used a falsy check instead of an explicit check for None. The result is that callers that passed in an empty list would have that list overridden by the defaults, which is not the expected behavior. This was discovered by changes to the test-pushrebase.t test in Facebook's repository of mercurial extensions.

import: report directory-relative paths in error messages (issue5224) Import uses paths relative to the root of the repository, so when user imports patch with paths relative to the current working directory import aborts with 'unable to find file for patching'. This patch improves this situation by warning the user that paths are relative to the root of repository when patching fails.

commands: remove unecessary copying of list in graft()

revset: do not partial-match operator and function names in optimize() It was error-prone, and actually there was a typo, s/ancestorspec/ancestor/.

revset: remove false condition to process 'negate' operator 'negate' is mapped to 'string' at the above clause.

revset: make optimize() reject unknown operators This should have caught the bug of 'keyvalue' operator fixed at 5004ef47f437. The catch-all pattern is useless since optimize() should be aware of all known operators.

help: show content for explicitly disabled extension (issue5228)

obsolete: fix minor module documentation issues

debugextensions: hide "ships-with-hg-core" magic string (BC) Since we have "bundled" flag, we no longer need to rephrase "ships-with-hg-core" to show as "internal".

debugextensions: show ships-with-hg-core state as a separate field This is less magical than rephrasing ships-with-hg-core as internal, and we can distinguish "internal" liar. "tested with: internal" will be hidden by the next patch.

test-debugextensions: add dummy extension to make ifcontains() test more solid If testedwith were a string, ifcontains("3.2", testedwith) would match "3.2.1". New test added to cover that.

py3: remove use of *L syntax The int in Python 3 behaves as long so no need of L's in py3. Moreover we dont need long here.

util: rename checkcase() to fscasesensitive() (API) I always read the name "checkcase(path)" as "do we need to check for case folding at this path", but it's actually (I think) meant to be read "check if the file system cares about case at this path". I'm clearly not the only one confused by this as the dirstate has this property: def _checkcase(self): return not util.checkcase(self._join('.hg')) Maybe we should even inverse the function and call it fscasefolding() since that's what all callers care about?

manifest: call m1.load and m2.load before writing a subtree As part of refactoring the manifest, certain test cases started failing because writesubtrees was called with p1 and p2 manifests that had not been loaded (so accessing m1._dirs resulted in an empty set). Let's call _load on these before attempting to access _dirs. This was caught by tests when future patches were applied.

histedit: correct output of error when 'base' is from the edit list This was made more obvious by marmoute's recent rearrangement of this code.

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.
