py3: use pycompat.strkwargs() to convert kwargs' key to str Differential Revision: https://phab.mercurial-scm.org/D2043

py3: add __bytes__() for mq.patchheader and make sure __str__ returns str Before this patch, __str__() function for mq.patchheader class return bytes which is not str on Python 3. So let's move that logic to __bytes__() and for __str__() convert the return value of __bytes__() to str. Differential Revision: https://phab.mercurial-scm.org/D2042

py3: use "%d" to convert integer to bytes Differential Revision: https://phab.mercurial-scm.org/D2041

py3: use .startswith() instead of bytes[0] Differential Revision: https://phab.mercurial-scm.org/D2040

py3: slice on bytes to prevent getting the ascii values Differential Revision: https://phab.mercurial-scm.org/D2039

py3: add r'' to convert keys to keyword arguments to str # skip-blame as we are just adding r'' Differential Revision: https://phab.mercurial-scm.org/D2038

py3: add b'' to tweakdefaults config string The tweakdefaults config string is enclosed inside triple quotes and the transformer does not adds b'' there. # skip-blame because we are just adding b'' Differential Revision: https://phab.mercurial-scm.org/D2037

cmdutil: introduce deprecated aliases c8e2d6ed1f9e moved some objects used by Evolve and hence broke the latest Evolve revision. Next Evolve version will use the new objects when available but introduce deprecated aliases so users using older version of Evolve won't have a broken Evolve extension.

makefile: remove Ubuntu Yakkety and Zesty docker targets Yakkety (16.10) was supported until 2017-07-20 and Zesty (17.04) was supported until 2018-01-13.

merge: use operation-provided labels (ex: dest/source) in several merge-tools Tools that did not use labels already, used only one, or used some label other than the exact strings of "local" or "other" were unmodified. Cases that used the label "base" were modified as well, if they were otherwise changed in this CL; "merged" was *not* changed. There are other possible changes we might want to make, but I didn't: - bcompare (linux and osx) uses the labels "parent1" and "parent2" instead of "local" and "other", so it was left alone, even though beyondcompare3 (windows) *was* changed. - araxis used the labels "Other", "Base", and "Local :$local", so it was also left alone. - UltraCompare didn't provide a label for 'local', just for 'base' and 'other', so it was left alone.

filemerge: support passing labels to external merge tools This adds $labellocal, $labelother, and $labelbase to the replacement set for merge-tools.<tool>.args config variables, and to the environment as HG_MY_LABEL, HG_OTHER_LABEL, and HG_BASE_LABEL, respectively. We also add merge-tools.<tool>.mergemarkers and merge-tools.<tool>.mergemarkertemplate config variables as counterparts of the variables available in [ui]. We are intentionally *not* respecting ui.mergemarkers when calling out to external merge programs; too often the default template will be too wide to display comfortably in most GUIs.

bookmarks: drop deprecated methods (API) The ProgrammingError prevents accidental usage of the dict base class methods. .. api:: The following deprecated methods have been removed from bookmarks: __setitem__(), __delitem__(), update(), and recordchange(). Use bookmarks.applychanges() instead.

archive: rewrite default metadata template as a multi-line bytes literal This fixes test-directaccess.t on Python 3.

py3: drop b'' from repr() of smartset cmdutil._maybebytestr() is moved to pycompat.

py3: always drop b'' prefix from repr() of bytestr Perhaps this is what we wanted for py2-3 compatibility.

py3: format revision number as '%d' in debugrevspec Now "hg debugrevspec" works on Python 3.

py3: build repr() of smartset as bytes then convert to str This isn't pretty, but we have no way to teach Python 3 that our __repr__() would like to return a byte string.

py3: factor out helpers to apply string conversion recursively

py3: replace "if ispy3" by pycompat.sysbytes() or util.forcebytestr()

py3: replace "if ispy3" by pycompat.bytestr()

py3: replace "if ispy3" by encoding.strtolocal()

localrepo: drop the deprecated walk() method (API) .. api:: The deprecated localrepo.walk() has been removed, and replaced by repo[node].walk().

dirstate: drop deprecated methods (API) .. api:: beginparentchange() and endparentchange() have been replaced by the parentchange context manager.

templatekw: drop the deprecated '{troubles}' keyword

obsutil: drop deprecated methods (API) .. api:: The following deprecated methods have been removed from obsutil: marker.precnode() and allprecursors(). Use marker.prednode() and allpredecessors() instead.
