color: restore _style global after debugcolor ran Before this change, running 'debugcolor' would destroy all color style for the rest of the process life. We now properly backup and restore the variable content. Using a global variable is sketchy in general and could probably be removed. However, this is a quest for another adventure.

color: add basic documentation to 'debugcolor' This does not hurt.

tests: merge 'test-push-hook-lock.t' into 'test-push.t' That test file is very small and is merge with the new 'test-push.t'. No logic is changed. We don't register this as a copy because is actually a "ypoc" merging two file together without replacing the destination and Mercurial cannot express that.

tests: merge 'test-push-validation.t' into 'test-push.t' That test file is very small and is merge with the new 'test-push.t'. No logic is changed but repository name are update to avoid collision. We don't register this as a copy because is actually a "ypoc" merging two file together without replacing the destination and Mercurial cannot express that.

test: rename 'test-push-r.t' to 'test-push.t' We do not have a simple test for 'hg push' but we have multiple tiny tests for various aspect of it. We'll unify them into a single file, and we start with 'test-push-r.t'. The code is unchanged but we renamed the repository used to avoid collision with other tests we'll import in coming changesets. Test timing for the record: start end cuser csys real Test 1.850 2.640 0.650 0.090 0.790 test-push-validation.t 2.640 3.520 0.760 0.090 0.880 test-push-hook-lock.t 0.000 1.850 1.560 0.210 1.850 test-push-r.t

tests: simplify command script in 'test-push-r.t' I came across this code by chance. The script of this test is a bit messy with a lot of unnecessary intermediate commands. We simplify the script and unify repository access through '-R'. In the process the update after the unbundle is dropped as it does not add anything to the tests.

py3: use encoding.environ in ui.py Using source transformer we add b'' everywhere. So there are no chances that those bytes string will work with os.environ on Py3 as that returns a dict of unicodes. We are relying on the errors, even though no error is raised even in future, these pieces of codes will tend to do wrong things. if statements can result in wrong boolean and certain errors can be raised while using this piece of code. Let's not wait for them to happen, fix what is wrong. If this patch goes in, I will try to do it for all the cases. Leaving it as it is buggy.

py3: make scmposix.userrcpath() return bytes We are making sure that we deal with bytes as much we can. This is a part of fixing functions so that they return bytes if they have to. Used encoding.environ to return bytes. After this patch, scmposix.userrcpath() returns bytes and scmutil.osrcpath() will also return bytes if the platform is posix. Functions is scmposix returns bytes on Python 3 now.

adjustlinkrev: remove unnecessary parameters Since adjustlinkrev has "self", and is a method of a filectx object, it does not need path, filelog, filenode. They can be fetched from the "self" easily.

repair: make strip() return backup file path narrowhg wants to strip some commits and then re-apply them after applying another bundle. Having repair.strip() return the bundle path will be helpful for it.
