templatekw: drop obsfateprinter() and obsfatelineprinter() They were unused (probably because their versions were already pushed to hg 4.4).

compat: drop isobsnotesupported() that checks if storing notes is supported The check is identical to checking if core has e27f1f04c2cf (hg 4.4).

templatekw: use literal set syntax According to https://www.mercurial-scm.org/wiki/SupportedPythonVersions, we don't support Python 2.6 since 4.3.

obshistory: remove obsfateverb/obsfateprinter patching compatibility obsutil.obsfateverb() was introduced in 3d0f8918351b (hg 4.4) and renamed in b81ad5b78a81 (hg 4.5). Considering the supported evolve versions, the first check is unnecessary (the condition is always True) obsutil.obsfateprinter() was introduced in e27f1f04c2cf (hg 4.4).

obshistory: drop unused keyword argument to _getobsfateandsuccs()

obshistory: use successorsandmarkers() from obsutil, drop local variant It's been in core since 4.4 and is identical to the version removed by this patch, except it returns None if ctx is not obsolete.

compat: drop code from 35b2d201eb71 (compatibility with hg 4.3)

tests: rename precursors to predecessors in test-evolve-templates.t

evolve: correct spelling of superseded everywhere else

evolve: use obsutil._getobsfate() directly It's been there since 4.5 (265cd9e19d26), we can safely rely on it. It's necessary though to use the correct spelling of superseded.

evolve: remove dead code

evolve: use utility._singlesuccessor() in _solveunstable()

evolve: preliminary indentation The whole code will end up in a try/except clause. We pre-indent the code to clarify the next patch.

evolve: provide cache argument to obsutil.successorssets() correctly After 68f3e819d41d (4.3) the 3rd argument to that function is `closest`.

pullbundle: random.sample() chokes on a spanset, turn it into a list instead On Python 3.

pullbundle: use % instead of .format() because % exists for bytes

tests: test that debugpullbundlecacheoverlap command works

pullbundle: compatibility for progress in hg <= 4.6

compat: add hg version to progress compatibility code

serverminitopic: ask pytype to disable import-error on a block handling hg 4.5

topic: ask pytype to disable import-error on a block handling hg 4.5

evolve: remove unused struct import

compat: ask pytype to ignore some warnings It's expected to have a bunch of import and attribute errors in this module because it's for compatibility with different versions of hg and Python. Although it doesn't explain why a function wouldn't have __code__ attribute? So far I think it's a quirk of pytype.

evolve: extract logic of pre-checking divergence risk to its own function Extracting the logic (which is used to check if rewriting an obsolete revision will create divergence) to a function. This function will be used in upcoming patches of pre-checking. This is how we check if rewriting an obsolete revision will create divergence. We need to check two cases: If there is any 1) non-obsolete successor. -> easily done by `obsutil.successorssets()` 2) precursor with non-obsolete successor. -> using `evolvecmd.divergentsets()`
