bisect: move the 'extendrange' to the 'hbisect' module We have a module ready to host any bisect logic. That logic was already isolated in a function so we just migrate it as is.

bisect: extract the 'reset' logic into its own function This is part of small clean up movement. The bisect module seem more appropriate to host the bisect logic. The cleanup itself is motivated by some higher level cleanup around vfs and locking.

bisect: access the filesystem through vfs when reseting We have nice and shiny abstractions now.

util: remove the copypasta unquote function The _urlunquote function was added back in the day to improve startup performance, but this version is a) not compatible with Python 3 and b) has quadratic performance issues that Python core solved eons ago. Moreover, the function moved from urllib to urlparse (cheaper to import) *and* that module is already imported into pycompat. As a result, removing this function improves perf now. Before: ! wall 0.066773 comb 0.000000 user 0.000000 sys 0.000000 (best of 100) After: ! wall 0.065990 comb 0.000000 user 0.000000 sys 0.000000 (best of 100)

merge: add conflict labels to merge command Now that we present the conflict labels in prompts, it's useful to have better names than "local" and "other" for every command.

check-commit: allow underscore as commit topic It's currently not possible to commit with a changeset topic like 'bash_completion'. This change fixes that.

merge: use labels in subrepo merge This is the last place that doesn't respect conflict labels in merge output. Teach subrepos to use subrepo merge output too.

registrar: make format strings unicodes and not bytes Fixes issues on Python 3, wherein docstrings are unicodes. Shouldn't break anything on Python 2.

extensions: move the "import" logic out from "load" The "load" method does too many things: on-demand import and check version. This patch moves the import logic out from "load" so it could be wrapped to change the import behavior, for example, chg will use it to pre-import extensions.

hgmanpage: stop using raw-unicode strings These don't exist in Python 3, and this ends up looking a little more explicit to Martijn and me anyway.

revset: define _symletters in terms of _syminitletters

revset: remove doubled space

util: use string.hexdigits instead of defining it ourselves This resolves some Python 3 weirdness.

util: correct check of sys.version_info sys.version is a string, and shouldn't be compared against a tuple for version comparisons. This was always true, so we were never disabling gc on 2.6. >>> (2, 7) >= '2.7' True >>> (2, 6) >= '2.7' True

py3: switch to .items() using transformer .iteritems() don't exist in Python 3 world. Used the transformer to replace .iteritems() to .items()
