doc: don't use mutable default arguments It appears our mutable default arguments checker doesn't find arguments not on the first line of a function definition :( The arguments aren't used, so the default value is irrelevant.

tags: don't check for clean files when checking for dirty working copy We didn't request status for clean files so there should never be any entries in the list of clean files (at least not since dd773340a085), but it's misleading to check the list.

typing: add pseudo localstr.__init__() to help pytype Apparently, pytype failed to parse localstr.__new__()? This fixes the following errors: line 126, in __hash__: No attribute '_utf8' on localstr [attribute-error] line 188, in tolocal: Function localstr.__init__ was called with the wrong arguments [wrong-arg-types] Expected: (self, string: str, ...) Actually passed: (self, string: bytes, ...)

typing: fix argument type of encoding.localstr() It takes both utf-8 and local strings in bytes type.

typing: suppress error of py2 encoding.strtolocal() and .strfromlocal() I don't know how to conditionally get rid of these py2/py3 overloads from .pyi file. Instead, this patch makes pytype ignore the false-positives: line 271, in strtolocal: bad option in return type [bad-return-type] Expected: bytes Actually returned: str

typing: constrain argument/return types of encoding.toutf8b()

typing: fix argument type of encoding.tolocal() and .fromutf8b() Fixes various pytype errors.

typing: fix forward reference in _Tlocalstr type bound AFAIK, a quoted string in type position is translated to its ForwardRef. https://github.com/python/typing/issues/34 This fixes the following error: File "mercurial/encoding.py", line 38, in <module>: Name 'localstr' is not defined [name-error]

encoding: make getcols() raise exception explicitly This helps pytype. File "mercurial/encoding.py", line 329, in getcols: bad option in return type [bad-return-type] Expected: bytes Actually returned: None

setup: conditionalize access to `sys.dllhandle` when building extensions This code is only run on Windows, and was crashing PyOxidizer when running in `setup-py-install` mode. Now an oxidized binary can be built by simply pointing to setup.py. Something is slightly different now that it's not being built from a virtualenv. Previously, `hg version` could print to the screen, but now it aborts saying "Incorrect function". But I can see the output if redirected to a file, and it's not complaining about missing C extensions, so I think those are loading now (unlike from the virtualenv). The interesting this about this incorrect function output is that it failed when initially built. I then went back and did a `make clean` and `make local` with py3 and then py2 to ensure I didn't break the existing code. At that point I ran the oxidized executable again and it was able to print to the screen normally! So I ran `pyoxidizer build` again, it only output the following, and then running the executable failed to output again: (pyO2_venv) C:\Users\Matt\hg3\hg_pyO2>pyoxidizer build Finished dev [unoptimized + debuginfo] target(s) in 0.12s packaging application into C:/Users/Matt/hg3/hg_pyO2\build\apps\hg_pyO2\x86_64-pc-windows-msvc\debug purging C:/Users/Matt/hg3/hg_pyO2\build\apps\hg_pyO2\x86_64-pc-windows-msvc\debug copying C:/Users/Matt/hg3/hg_pyO2\build\target\x86_64-pc-windows-msvc\debug\hg_pyO2.exe to C:/Users/Matt/hg3/hg_pyO2\build\apps\hg_pyO2\x86_64-pc-windows-msvc\debug\hg_pyO2.exe resolving packaging state... writing license for [...] hg_pyO2 packaged into C:/Users/Matt/hg3/hg_pyO2\build\apps\hg_pyO2\x86_64-pc-windows-msvc\debug executable path: C:/Users/Matt/hg3/hg_pyO2\build\apps\hg_pyO2\x86_64-pc-windows-msvc\debug\hg_pyO2.exe Differential Revision: https://phab.mercurial-scm.org/D7444

util: remove datapath and swith users over to resourceutil The util module no longer needs the datapath for injecting it into the i18n module, so we can remove it from there and update other users. Differential Revision: https://phab.mercurial-scm.org/D7436

i18n: get datapath directly from resourceutil The new resourceutil module is lower in the dependency graph, so we can depend directly on it and won't have to depend on the util module to inject the datapath. Differential Revision: https://phab.mercurial-scm.org/D7435

util: move definition of datapath to resourceutil Since this means moving the function into a subdirectory, we have to compensate by adding another layer of os.path.dirname(). Differential Revision: https://phab.mercurial-scm.org/D7434

procutil: move mainfrozen() to new resourceutil.py The i18n module practically depends on procutil for mainfrozen() but since procutil depends on i18n, it would be a circular dependency if i18n depended directly on procutil. The cycle is currently resolved by having the higher-level util module calculate the "datapath" and inject it into i18n. Extracting mainfrozen() to a new module lets us clean up the dependencies.

histedit: render a rolled up description using the proper roll colours Users have rightfully complained that the old behaviour of completely removing the description of a rolled commit makes it difficult to remember what was in that commit. Instead, we now render the removed description in red. I couldn't think of a simpler way to do this. You can't just combine existing curses colours into new effects; only secondary effects like bold or underline can be logically OR'ed to generate a combined text effect. It seems easier to just redundantly keep track of what the roll colour should be.

histedit: define new colour pairs for roll action Red seems like a good colour to indicate removal, since that's the colour we use in diffs. We need three varieties with three different backgrounds corresponding to the possible ways we can display a rule.

histeditrule: split __bytes__ property into prefix and desc In order to be able to colourise the description of the rule, we need to have it as a separate bytestring. Curses doesn't make it easy to take existing text on the screen and give it different properties; we can only add new text with new properties.
