windows: use cpu-intensive task instead of real time in test Windows profiling breaks when using real time instead of cpu, but we need the extension function to show up, so make it do something instead of waiting. I've also duplicated the test cases so that explicit real and CPU times are tested (on platforms other than Windows) Differential Revision: https://phab.mercurial-scm.org/D11003

windows: use shell function instead of variable substitution This makes it compatible with Windows Differential Revision: https://phab.mercurial-scm.org/D11002

compat: normalise path before comparison in revlog splitting test This fixes the test on Window. Differential Revision: https://phab.mercurial-scm.org/D10999

windows: replicate the normalizing behavior of os.environ On Windows, `os.environ` normalizes environment variables to uppercase. Our current bytes-based environ substitution object is a simple dict, so we add the normalization behavior. This fixes test-http-peer.t on Windows.

encoding: move case-related utils up This will be useful for the next commit that needs this code earlier. Differential Revision: https://phab.mercurial-scm.org/D11024

dirstate: drop the last explicit `state` usage in the module The internal detail of the `state` bytes is not longer exposed to the dirstate layer. Differential Revision: https://phab.mercurial-scm.org/D10977

test: use a python script in `test-transaction-rollback-on-sigpipe.t` This still does not work on Windows, but at least this is a python script now. Differential Revision: https://phab.mercurial-scm.org/D10947

test: make sure we hit the SIGPIPE in test-transaction-rollback-on-sigpipe With a coming change, we might not hit the sig pipe without issue and extra line of output. We do this early to make the next change clearer. Differential Revision: https://phab.mercurial-scm.org/D10946

test: clarify some output in `test-transaction-rollback-on-sigpipe` We don't want a dirty transaction to remain, but need to check the transaction was aborted. Otherwise it is easy to have no abandoned transaction if the transaction succeed. Differential Revision: https://phab.mercurial-scm.org/D10945

tests: add test case for issue 6262 If you split a commit, prune one of the sides, and then try to revive that commit by adding a successor, it will incorrectly be considered divergence. Differential Revision: https://phab.mercurial-scm.org/D10916
