largefile: synchronise the dirstate within a `parentchange` context Semantically these changes are made to adjust the dirstate after a commit, so it should be in a `parentchange` context. Differential Revision: https://phab.mercurial-scm.org/D11103

upgrade_utils: fix crash for removecldeltachain action This fixes issue6383. Differential Revision: https://phab.mercurial-scm.org/D10914

windows: enforce the module policy to be c for test This is the same as what we do with the linux test. Differential Revision: https://phab.mercurial-scm.org/D11100

packaging: add command line flag to add extra vars to pyoxidizer This felt simpler than the previous incarnation of injecting content into the WiX build. I decided the easiest way to pass an arbitrary map into the process was some json - I may regret this, but time will tell on that. Differential Revision: https://phab.mercurial-scm.org/D11093

pyoxidizer: add hooks to inject extra python packages and install files We need this type of hook to inject our internal extension and resource files at Google. Presumably this could be useful to others, so instead of trying to carry an internal patch we've done this in a modular way that should be of value upstream. I'm extremely puzzled by the behavior of glob() on Windows, and I'll be filing at least one (probably two) bugs upstream about it. Differential Revision: https://phab.mercurial-scm.org/D11092

doc: wrap the help text for the purge extension Not sure why `black` or some other checker didn't complain about this. Differential Revision: https://phab.mercurial-scm.org/D11036

dummyssh: call python script with python We don't want windows to grab whatever python got configured to run .py file. We need the python used during the test to be used. Differential Revision: https://phab.mercurial-scm.org/D11083

dummyssh: use subprocess instead of os.call Welcome in 2020 Differential Revision: https://phab.mercurial-scm.org/D11082

run-test: rework the redirection script for python on windows This should get use something something overall simpler and clearer. Especially, we now have a `python.exe` script (even if by default Windows has `C:\Python27\python.exe` hardcoded in the register to open .py file) Differential Revision: https://phab.mercurial-scm.org/D11081

run-test: act that we requires MSYS to run the test on Windows If this ever change we can drop that constrains, however for now it seems clear to be clear about this limitation. Differential Revision: https://phab.mercurial-scm.org/D11080

sigpipe-remote: display more information about the non-py3 python If we are running the wrong things, it is useful to know which wrong thing we are running. Differential Revision: https://phab.mercurial-scm.org/D11079

sigpipe-remote: check for python version earlier in the script The should abort early, using the wrong python is a pretty bad sign. Differential Revision: https://phab.mercurial-scm.org/D11078

check-code: add a rules to catch os.path.abspath All previous usages have been migrated. So let us add a check-code rules to catch future usages. We restrict it to mercurial/ and hgext/ because multiple other script never depends on Mercurial modules. Differential Revision: https://phab.mercurial-scm.org/D11072

windows: use abspath in convert.subversion We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11071

windows: use abspath in convert.git We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11070

windows: use abspath in convert.bzr We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11069

windows: use abspath in the git extension We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11068

windows: use abspath in url We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11067

windows: use abspath in subrepoutil We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11066

windows: use abspath in subrepo We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11065

windows: use abspath in hgwebdir We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11064

windows: use abspath in mercurial/hg.py We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11063

windows: use abspath in extensions We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11062

windows: use abspath in commandserver We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11061

windows: use abspath in chgserver We replace `os.path.abspath` with `util.abspath`. This should solve more "drive capitalization" issue on Windows. Differential Revision: https://phab.mercurial-scm.org/D11060

windows: introduce a `util.abspath` to replace os.path.abspath This will let us mitigate the drive letter capitalization hell. See inline comment for details. Differential Revision: https://phab.mercurial-scm.org/D11059

windows: enforce upper case drive letter for getcwd in mercurial too This is affecting code that checks if a pull/push destination is the same as a configured one. For example the one creating divergent bookmark. Doing this fixes will help fixing `test-bookmarks.t` and `test-bookflow.t` on Windows. However, we also need to fix `abspath` invocation. Differential Revision: https://phab.mercurial-scm.org/D11058

hg-ssh: normalize the drive of the current working directory on windows For some reason os.getcwd() can return either `c:` or `C:`. We normalize this to `C:` and the like. This fix `test-ssh-bundle1.t` on windows. Differential Revision: https://phab.mercurial-scm.org/D11042

run-tests: enforce the drive letter from `getcwd` to upper case For some reason os.getcwd() can return either `c:` or `C:` depending of which binary you used on Windows. We normalize this to `C:` and the like. This fix `test-run-tests.t` on windows as the drive letter in "$TESTTMP" was "wrongly" set to 'c:/' if the test path wasn't explicitly specified. Differential Revision: https://phab.mercurial-scm.org/D11035

sigpipe-remote: simply delegate pipe forwarding to subprocess we can kill Instead of using sophisticated logics with thread a non blocking pipes, we simply spawn two new process in charge of reading the pipe and sending the result to the client. When it is time to cut the pipe we violently kill them without any remorse. This close the pipe regardless of any in progress `os.read` call. Ironically this is the very same things as what the initial shell setup was doing, but in Python. This makes the test pass run properly on Windows. This also reveal that the Windows behavior is broken as the transaction is not properly rollback. However this is an adventure for another time. Making the test behave properly was enough effort.
