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.

rebase: check for conflicts before continuing When there are unresolved merge conflicts, there is no reason to make the user wait for rebase to process all of the already rebased commits just to complain that it cannot do anything. Abort early.

cmdutil: refactor checkunresolved localrepo.commit had code to check for unresolved merge conflicts, it would be helpful for at least rebase to be able to use that code without calling commit().

rebase: rename merge to mergemod

context: make sure __str__ works, also when there is no _changectx Before, it could crash when trying to print the wrong kind of object at the wrong time.

largefiles: clarify variable name holding file mode A follow-up to c01acee367ec. 'st' sounds like the whole stat result while 'mode' is a better name for the actual file mode.

changegroup: use changelogrevision() Using offsets for accessing changelog entries isn't very readable. As a bonus, changelog.changelogrevision() also accepts a revision, so we don't need to perform the inline node resolution either.

changegroup: cache changelog and manifestlog outside of loop History has taught us that repo.changelog can add significant overhead to loops. So cache the changelog instance outside of the loop to avoid the lookup. While we're here, do the same for manifestlog, since each loop would otherwise initialize a new manifestlog instance.

make: targets for building packages for ubuntu yakkety Ubuntu 16.10 Yakkety Yak is out. Let's support it.

util: put compression code next to each other ctxmanager was injecting itself between the compression and decompression code. Let's restore some order.

hgweb: make log streams compatible with command server Even though it would be useless to start a web server by a command server, it should be doable in principle. Also, we can't use sys.stdout/err directly on Python 3 because they are unicode streams.

cmdserver: write channel header and payload by a single write() call This makes a channeledoutput thread-safe as long as the underlying fwrite() is thread-safe. Both POSIX and Windows implementations are documented as MT-safe. MT-safety is necessary to use ui.fout and ui.ferr in hgweb.

histedit: use ui.fin to read commands from stdin stdin is wrapped by channeledinput in command-server session.

convert: have debugsvnlog obtain standard streams from ui This will help porting to Python 3, where sys.stdin/out/err are unfortunately unicode streams so we can't use them directly.

convert: remove superfluous setbinary() calls from debugsvnlog a3fe91b4f6eb made standard streams set to binary mode globally.

tests: explicitly use ls profiler In preparation for making the statprof profiler the default.

statprof: pass data structure to display functions Currently, statprof maintains a global "state" variable that is used by several functions. Global variables hinder adaptability of code. So pass state to display functions so we can make changes to how "state" works in future patches.

statprof: use print function

statprof: use absolute_imports As part of this, we modify import order to satisfy our import checker.

statprof: require paths to save or load profile data Upstream appears to aggressively save statprof data in a well-defined home directory path. Change the code to not do that. We also change file saving to fail if an error has occurred instead of silently failing. Callers can catch the exception. This behavior is more suitable for a generic "library" module.
