devel: use the new 'config' argument for the dirstate develwarn

devel: use the new 'config' argument of the develwarn in deprecwarn Controling all deprecation warnings with the same config seems sensible. This mirror a fix (about missing gating) submitted for stable but with the new API.

develwarn: move config gating inside the develwarn function The config gating is almost always the same and contributor tend to forget it. We move the logic inside the function. Call site will be updated in later changeset. We might make the sub config mandatory in the future (once all old call sites are gone).

help: fix the display for `hg help internals.revlogs` (issue5227) It previously aborted saying the help section wasn't found. Credit to Yuya for figuring out the fix.

builddeb: add distroseries to tagged versions This is needed so that launchpad and friends have a unique version number for each distroseries (trusty, wily, xenial, etc). It was discovered when trying to upload 3.8 to launchpad.

debian: forgot to make debian/rules executable in 6b95a623ec90

debian: add wish to suggests Debian maintainers already have this and lintian warns us about not listing 'wish' as a dependency or suggestion so this patch does indeed just that. The issue, by the way, is that we are shipping hgk (which is written in tcl/tk) so we should be good citizens and list wish (a meta package for tcl/tk) as a dependency.

hg-ssh: copy doc string to man page This corrects a warning from lintian that we're shipping an executable without a man page. Since there is a doc string in the text, let's use that for the man page.

progress: stop excessive clearing (issue4801) The progress bar was being cleared on every write(), regardless of whether it was currently displayed. This could foul up the display of any writes that didn't include a linebreak. In particular, the win32 mode of the color extension was turning single prompt string writes into two writes, and the resulting clear/write/clear/write pattern was making the prompt invisible. We fix this by insisting that we have shown a progress bar and haven't just cleared it (setting lastprint to 0). Conveniently, the test suite already had instances of duplicate clears.. that are now cleared up.

chgserver: remove _clearenvaliases Since we expand environment variables in alias lazily, the _clearenvaliases hack is no longer necessary. This resolves an issue that a non-shell alias which has environment variables in its arguments and is set to use pager will not use pager running with chg.

dispatch: defer environment variable resolution in alias commands (BC) Before this patch, if there are environment variables in an alias command, they will be expanded immediately when we first see the alias. This will cause issues with chg, because environment variable updates will not propagate to expanded arguments. This patch makes "args" of "cmdalias" a property that will be calculated every time when accessed.

rollback: add a config knob for entirely disabling the command This is of pretty high value for organizations that used to use p4 (as an example), since `p4 rollback` is what we call `hg backout`.

templater: add separate() template function A pretty common pattern in templates is adding conditional separators like so: {node}{if(bookmarks, " {bookmarks}")}{if(tags, " {tags}")} With this patch, the above can be simplified to: {separate(" ", node, bookmarks, tags)} The function is similar to the already existing join(), but with a few differences: * separate() skips empty arguments * join() expects a single list argument, while separate() expects each item as a separate argument * separate() takes the separator first in order to allow a variable number of arguments after it

bookmarks: jettison bmstore's write() method per deprecation policy

merge with stable

deprecation: gate deprecation warning behind devel configuration Regular users are not supposed to be exposed to the API deprecation warnings. We now only issue them when the developper warnings are enabled.

crecord: update downarrowshiftevent() docstring, remove todo The phrasing is mostly taken from uparrowshiftevent().

crecord: remove things that don't happen in functions from their docstrings Scrolling screen is currently done in a different place. The things that had been described in the docstrings may still happen, but the functions touched by this patch don't do any scrolling, they only set self.currentselecteditem and nothing more.

crecord: remove skipfolded keyword argument from patchnode.previtem() It wasn't used, it wasn't implemented. Probably was a copy-paste bonus from patchnode.nextitem()

crecord: update a copy-pasted comment in downarrowshiftevent()

crecord: drop the version condition for amend The UI is now shipped in core, amend feature is always available.

crecord: add/remove blank lines (coding style)

localrepo: jettison parents() method per deprecation policy (API)

revset: define _parsealias() in _aliasrules class It's short. It doesn't make sense to define _parsealias() outside of the class.

revset: factor out common parsing function

revset: inline _tokenizealias() into _parsealias() This helps factoring out common part between _parsealias() and parse().

store: treat range as a generator instead of a list for py3 compat

ui: add new config option for help text width Before this patch, when printing help text using `hg help`, or `hg log -h`, the output will wrap at 78 chars even if the user has a bigger terminal width and there is no config option to change it, making the experience different from the commonly used `man` tool. This patch introduces a new config option `ui.textwidth`, which replaces the hardcoded number. It's set to 78 by default to maintain compatibility. When set to 0, `hg help` will behave more like `man`.
