test-revlog-mmapindex: make it compatible with chg The test misses an explicit flush(). Differential Revision: https://phab.mercurial-scm.org/D918

test-profile: gate chg-incompatible part with '#if chg' chg has a different extension loading logic, which affects the profiler extension test case. Gate the block with '#if chg' so the test passes with chg. Differential Revision: https://phab.mercurial-scm.org/D916

test-logtoprocess: make it compatible with chg chg runs more commands and outputs more lines. This patch matches them. Differential Revision: https://phab.mercurial-scm.org/D914

test-globalopts: make the test compatible with chg The test fails when run with the '--chg' option. Therefore, this commit modifies the test to make it compatible with chg. Test Plan: Ran 'test-globalopts.t' with and without the '--chg' option. Differential Revision: https://phab.mercurial-scm.org/D913

test-pager: make it compatible with chg chg's runpager implementation is different. It behaves differently for the "shell=False, command not found" case. Differential Revision: https://phab.mercurial-scm.org/D911

changelog: use a Factory for default value for files The default value is compiled into the generated type. This means that default values are shared between instances. For immutable types like bool, str, int, and tuple, this is fine. But for mutable types like list and dict, we need to use attr.Factory() to instantiate a new instance of the default for each object.

cext: wrap before brace for functions This is our prevailing style. Differential Revision: https://phab.mercurial-scm.org/D910

cext: put case statements on separate line This seems to be the prevailing style, even though it is a bit more verbose for very simple switch statements. Differential Revision: https://phab.mercurial-scm.org/D909

cext: reorder #include We mostly abide by this style. In one case, a blank line was inserted to prevent a local `#include "file"` from coming before a `#include <file>`. Differential Revision: https://phab.mercurial-scm.org/D908

cext: move braces for control statements to same line This seems to be the prevailing style in the code by a wide margin. Differential Revision: https://phab.mercurial-scm.org/D907

registrar: fixing typo in comment I was just going through the module and noticed the typo. This commit fixes 'onfalure' -> 'onfailure'. Differential Revision: https://phab.mercurial-scm.org/D906

style: never put multiple statements on one line Differential Revision: https://phab.mercurial-scm.org/D905

annotate: mark lines affected by skip-annotate with * This is to prevent weird surprises from happening with skips being attributed to the wrong changeset. .. feature:: `hg annotate --skip` now prints a `*` on lines with skipped revisions Differential Revision: https://phab.mercurial-scm.org/D900

annotate: track whether a particular annotation was the result of a skip We're going to expose this information in the UI in an upcoming patch. Differential Revision: https://phab.mercurial-scm.org/D899

annotate: introduce attr for storing per-line annotate data We're going to extend this a bit -- at first by simply adding whether this was a skipped child. We're well on our way to outgrowing tuples, though -- adding more and more fields to tuples becomes annoying very quickly. Differential Revision: https://phab.mercurial-scm.org/D898

context: rename local 'attr' to 'attr_' In the next diff we're going to import mercurial.thirdparty.attr, and pyflakes complains about this if this rename isn't done. Differential Revision: https://phab.mercurial-scm.org/D897

annotate: move annotatepair unit tests to a separate file In upcoming patches the output is going to be significantly longer than it is today, and doctests don't allow wrapping the output. Differential Revision: https://phab.mercurial-scm.org/D896

check-code: allow an exception for camelcase where required unittest has a `maxDiff` parameter which has to be set to `None` in order for large enough failure diffs to be displayed. Add a comment to disable the camelcase check for `self.maxDiff = None` lines. Differential Revision: https://phab.mercurial-scm.org/D895

keepalive: python 3 portability tweaks Differential Revision: https://phab.mercurial-scm.org/D888

httppasswordmgrdbproxy: specify exact arguments We only ever call these functions in a single way, so let's just actually specify them. We need to do some string/bytes encoding dancing here for Python 3, so it'll help to know what arguments we need to convert. # no-check-commit because I'm modifying functions that check-commit does not like. Differential Revision: https://phab.mercurial-scm.org/D885

formatter: fix default list/dict generator to be evaluated more than once Before, _hybrid.gen must be a generator which could be consumed only once. It was okay in templatekw.py since template keywords are functions which create temporary hybrid objects, but the formatter doesn't work in that way. To work around the issue, this patch makes _hybrid.gen optionally be a function returning a generator. Thanks to Pulkit for finding this issue.

doctest: drop hack to run py2/3 tests selectively All doctests pass on Python 3.
