incoming: fix incoming when a local head is remotely filtered (issue3805) In its current state discovery may return (remotely) filtered elements in "common". This has usually no impact as "missing" is kept clear of filtered elements. However when the "remote" repo is a local repo (disk accessible, and directly created in memory) the incoming code takes a shortcut and directly uses the "remote" repo to generate the incoming output. When some common elements are filtered this led to a crash. We now ensure we use an unfiltered repository to generate the incoming output. This does not change the behavior as missing is clear of filtered revision. Now that we have proper low level filtering, incoming code needs a deeper cleanup but it is already planned.

dirstate: move pure python dirstate packing to pure/parsers.py

bookmark: don't allow integers as bookmark/branch/tag names Bookmarks/branches/tags shouldn't be allowed to be integers because that overlaps with revision numbers. Right now if a user created one they can't use it anyway because the revision numbers take precedence. The check only happens when creating a new bookmark/etc from a command so it shouldn't affect existing bookmarks/branches/tags or importing branches from git. This fix was prompted by us having a user create a bookmark named "404" then accidentally checkout a very old version of our repository.

run-tests: do not fail on empty tsttest file Initialize n for not failing on empty tsttest files.

hgweb: make 'summary' work with hidden changesets (issue3810) Since the 'summary' view used by e.g. gitweb and monoblue shows both a changelog and a bookmarks list, the same changes are needed here as were made to the 'changelog' and 'bookmarks' web commands (56ca4443a343 and 886936ecc21b, respectively).

hgk: support the old way of getting the current Ttk theme (issue3808) It seems like the API has changed somewhere around 8.5.7, so the preferred way of getting the current theme is now [ttk::style theme use], while the deprecated (but still working) is $::ttk::currentTheme.

addremove: don't perform m.exact/rel until needed Moves the m.exact and m.rel calls within the conditionals they are used in. On a large repo this brings addremove from 7.1 seconds down to 6.3 (13%).

addremove: don't call lexists, isdir, and islink The dirstate walk results contain the stat information for each path, so we don't need to query it again. On a large repo this makes addremove go from 8.35 seconds to 7.1 (15%).

addremove: only query dirstate once per path Previously the addremove code queried the dirstate 4 times per path. Now it only does so once. On a large repo this brings addremove from 9.5 seconds to 8.35 seconds (12%).

largefiles: don't crash when trying to find default dest for url without path b32e55e6c3c7 introduced a crash when cloning a url without path - where util.url().path would be None. This None will now be handled as ''. clone will thus abort with 'repository / not found' as before.

hgweb.cgi: fix internal WSGI emulation (issue3804) The internal WSGI emulation in wsgicgi.py was not fully WSGI compliant and assumed that all responses sent a body. With 3fbdbeab38cc that caused a real bug when using hgweb.cgi. wsgicgi.py will now make sure headers always are sent, using the pattern from PEP 333 and similar to how it is done in c007e5c54b16.

bdiff: simplify overflow checks Rather than check that each delta start, end, and length is within 32 bits, we simply check that the input strings are under 4GB.

rebase: derive node from target rev (issue3802) dest.rev() is the same as target when a new rebase is run, but dest isn't set when rebase --continue is run. Bug introduced in 2a1fac3650a5, which fixed issue3685.

profiling: introduce limit configuration option The number of output lines was hardcoded to 30. There was a 'nested' configuration options that controlled something else related to counting the number of output lines. This introduces the profiling.limit configuration option for controlling the number of profiling output to show.

largefiles: make verify --lfa and --lfc work without --large The slightly obscure --lfa and --lfc only worked as modifiers to --large and could be combined. The documentation was however not clear what they did. Instead they now imply --large and the description is updated.

largefiles: verify status should be written as status, not as write Make 'hg verify --large -q' quiet when no errors.

largefiles: report localstore errors with single line warnings messages The actual hash is also not relevant to report. This makes verify output with multiple failures easier to process.

merge: inline act() The act function had become very trivial and mainly shuffled arguments around and made it harder to see what really was going on.

merge: don't indent "local changed %s which remote deleted" prompt It was usually not shown in a context where indentation helped readability and it was inconsistent with other prompts.

merge: backout manifest sorting and workarounds for cost of it Backout 8a811fa9a9c0 and 760c0d67ce5e which no longer are needed.

merge: delay debug messages for merge actions Show messages at a point where the actions have been sorted, thus preparing for backout of 760c0d67ce5e. This makes manifestmerge more of a silent operation, just like 'copies' is. Indent 'preserving' messages to make them subordinate to the action logging so they fit in the new context. (The 'preserving' messages are quite redundant and could also be removed completely.)

merge: make all action tuples have the same length - keep args as tuple
