test-extdiff: narrow the range of an '#if execbit' block
Now that output can be conditionalized, the few `chmod +x` specific outputs can
be conditionalized, and the rest of the tests run as normal. Disable one test
that is failing on Windows for now.
policy: eliminate ".pure." from module name only if marked as dual
So we can switch cext/pure modules to new layout one by one.
policy: add "cext" package which will host CPython extension modules
I'm going to restructure cext/pure modules and get rid of our hgimporter
hack. C extension modules will be moved to cext/ directory so old and new
compiled modules can coexist in development tree. This is necessary to
run 'hg bisect' without recompiling.
New extension modules will be loaded by an importer function:
base85 = policy.importmod('base85') # select pure.base85 or cext.base85
This will also allow us to split cffi from pure modules, which is currently
difficult because pure modules can't be imported by name.
policy: mark all string literals as sysstr or bytes
The policy module won't be imported early in future, which means string
literals will be processed by our Python 3 loader.
debuginstall: check C extensions only if they are loadable per policy
This check is useless in pure installation and I want to make it directly
import C extension modules.
osutil: proxy through util (and platform) modules (API)
See the previous commit for why. Marked as API change since osutil.listdir()
seems widely used in third-party extensions.
The win32mbcs extension is updated to wrap both util. and windows. aliases.
win32mbcs: wrap underlying pycompat.bytestr to use checkwinfilename safely
win32mbcs wraps some functions, to prevent them from unintentionally
treating backslash (0x5c), which is used as the second or later byte
of multi bytes characters by problematic encodings, as a path
component delimiter on Windows platform.
This wrapping assumes that wrapped functions can safely accept unicode
string arguments.
Unfortunately,
d1937bdcee8c broke this assumption by introducing
pycompat.bytestr() into util.checkwinfilename() for py3 support. After
that, wrapped checkwinfilename() always fails for non-ASCII filename
at pycompat.bytestr() invocation.
This patch wraps underlying pycompat.bytestr() function to use
util.checkwinfilename() safely.
To avoid similar regression in the future, another patch series will
add smoke testing on default branch.
