blackbox: guard against recursion from dirty check

tests: divorce blackbox test from test-dispatch.py I used test-dispatch.py to demonstrate what would happen if a log file changed from being readonly to writable, by having it replace a directory (proxy for readonly/not-writable) with a log file in between transactions of a running python process (proxy for Mercurial). This commit makes it easier for people to follow what the test is doing, by creating a real file that people can read.

templater: ignore orig/rej files If your mercurial/templates/ directory is dirty, then the template system would otherwise import duplicate templates from the .orig files and potentially try to parse .rej files. Since editing/reverting these templates isn't an unexpected action, and since they're in .hgignore, it's best that the template system know to skip them."

resolve: when pats do not match, hint about path: Suggest a command that would probably work.

shelve: changes getting opts values by get method When shelve is used by another extension that doesn't provide all necessary values in opts shelve raises KeyError exception. This patch fixes this by getting values from opts dictionary with get method.

contrib: remove references to 2to3 The custom porting fixers are removed. A comment related to 2to3 has been removed from the import checker. After this patch, no references to 2to3 remain.

check-code: remove redundant import style check We have a dedicated tool that checks for import conventions. Remove a redundant and less powerful check.

setup: remove support for 2to3 We want to run unaltered source on multiple Python versions. We won't be using 2to3 for Python 3 support.

run-tests: remove 2to3 support Our goal is to have 1 code base that works on 2.6, 2.7, and 3.5+. 2to3 won't be used. Stop passing it to setup.py.

histedit: adds hint how to reorder changesets at editor (issue3766)

revset: replace predicate by revsetpredicate of registrar To make all built-in predicates be known to hggettext, loading built-in predicates by loadpredicate() should be placed before fixing i18nfunctions but after all of predicate decorating.

revset: replace extpredicate by revsetpredicate of registrar This patch consists of changes below (these can't be applied separately). - replace revset.extpredicate by registrar.revsetpredicate in extensions - remove setup() on an instance named as revsetpredicate in uisetup()/extsetup() of each extensions registrar.revsetpredicate doesn't have setup() API. - put new entry for revsetpredicate into extraloaders in dispatch This causes implicit loading predicate functions at loading extension. This loading mechanism requires that an extension has an instance named as revsetpredicate, and this is reason why largefiles/__init__.py is also changed in this patch. Before this patch, test-revset.t tests that all decorated revset predicates are loaded by explicit setup() at once ("all or nothing"). Now, test-revset.t tests that any revset predicate isn't loaded at failure of loading extension, because loading itself is executed by dispatch and it can't be controlled on extension side.

registrar: define revsetpredicate to decorate revset predicate revsetpredicate is used to replace revset.predicate and revset.extpredicate in subsequent patches. This patch also adds loadpredicate() to revset, because this combination helps to figure out how the name of safe predicate is put into safesymbols. This patch still uses safesymbols set to examine whether the predicate corresponded to the 'name' is safe from DoS attack or not, because just setting func._safe property needs changes below for such examination. before: name in revset.safesymbols after: getattr(revset.symbols.get(name, None), '_safe', False) "automatic registration" described in help doc of revsetpredicate class will be achieved by the subsequent patch, which lists loadpredicate() up in dispatch.extraloaders.

registrar: introduce new class for registration to replace funcregistrar _funcregistrarbase differs from funcregistrar in points below: - every code paths should use same class derived from _funcregistrarbase to register functions in a same category funcregistrar expects (3rd party) extensions to use (a class derived from) delayregistrar. - actual extra setup should be executed in another function For example, marking revset predicate as "safe" is executed in a class derived from _funcregistrarbase, but putting name of "safe" predicate into safesymbols is executed in another function for it. funcregistrar expects derived classes to do so. New class is named as module private one, because code paths, which register functions, should use not it directly but one derived from it.

dispatch: make loading extra information from extension extensible This patch makes loading extra information from extension module at dispatching extensible. Factoring 'loadcmdtable()' into commands.py is a part of generalization of loading extra information. This extensibility assumes registration of new function like below, for example: - revset predicate - fileset predicate - template keyword - template filter - template function - internal merge tool - web command This patch requires not loader function itself but container module and the name of it, because listing loader function directly up implies actual loading module of it, even if it isn't used at runtime (for example, extensions don't always define revset predicate)

obsolete: fix n^2 marker computation behavior Previously, if you ran obsolete.createmarkers with a bunch of markers that did not have successors (like when you do a prune), it encountered a n^2 computation behavior because the loop would read the changelog (to get ctx.parents()), then add a marker, in a loop. Adding a marker invalidated the computehidden cache, and reading the changelog recomputed it. This resulted in pruning 150 commits taking 150+ seconds in a large repo. The fix is to break the reading part of the loop to be separate from the writing part.

bdiff: (pure) support array.array arrays (issue5130)

mq: restrict generated patch name to 75 characters (issue5117) Super long first line in description lead to very long file name that windows is unhappy about. We restrict the name to 75 char to avoid the issue. 75 seems fine and leave some extra room for '__#' suffix in case of conflict. I does not seems worthwhile to add a dedicated config option to configure the length. It can be done in the future if there is an actual user demand for it.

files: don't recurse into subrepos without a path or -S (issue5127) The 'm.always()' check was needed for when a path to 'sub1' is given, and 'sub1' contains a subrepo itself. But that also caused the automatic recursion when no path was given. Instead, force -S when printing a subrepo if the subpath is an exact match (which will unconditionally recurse once in the nested subrepo).

parsers: optimize filtered headrevs logic The old native head revs logic would iterate over every node, starting from 0, and check if every node was filtered (by testing it against the filteredrevs python set). On large repos with hundreds of thousands of commits, this could take 150ms. This new logic iterates over the nodes in reverse order, and skips the filtered check if we've seen an unfiltered child of the node. This saves approximately a bagillion filteredrevs set checks, which shaves the time down from 150ms to 20ms during every branch cache write.

destutil: choose non-closed branch head at first (BC) Before this patch, destupdate() returns the tipmost (descendant) branch head regardless of closed or not. But updating to closed branch head isn't reasonable for ordinary workflow, because: - "hg heads" doesn't show closed heads (= updated parent itself) by default - subsequent committing on it re-opens closed branch even if inactivation of closed head is needed, update destination isn't it, because it should be merged into to another branch in such case. This patch chooses non-closed descendant branch head as default update destination at first. If all descendant branch heads are closed, destupdate() returns the tipmost closed branch head. For simplicity, this patch chooses adding _destupdatebranchfallback() instead largely changing _destupdatebranch(). This patch changes not only normal lookup code path, but also the "no default branch" code path, for consistency.

formatter: make labels work with templated output To describe the bug this fix is addressing, one can do ``$ hg status -T "{label('red', path)}\n" --color=debug`` and observe that the label is not applied before my fix and applied with it.

graphmod: augment the graph to include more information about the edges The walker knows when an edge leads to a direct parent, a grandparent (skipping revisions not part of the revset) and parents that are missing altogether (neither it nor a grandparent is in the revset). Add this information to the parents sequence yielded.

graphmod: refactor state handling Move ASCII graph state to a dictionary, to clarify what is being tracked. Move the 'seen' state (tracking currently active edges) into this structure.

templater: move label() function from color extension ui.label() is no-op by default, so we can just call ui.label() by label() template function no matter if the color is enabled or not.

templater: make label() take unknown symbol as color literal Instead of the mapping hack introduced by b775a2029e8d, this patch changes the way how a label symbol is evaluated. This is still hackish, but should be more predictable in that it doesn't depend on the known color effects. This change is intended to eliminate the reference to color._effects so that color.templatelabel() can be merged with templater.label().
