tests: don't load strip extension via mq extension for remotefilelog tests The proper way to get the `hg strip` command has been via the "strip" extension since 2013. Differential Revision: https://phab.mercurial-scm.org/D5250

remotefilelog: remove unused configs for {data,history}pack version Differential Revision: https://phab.mercurial-scm.org/D5249

tests: remove obsolete PYTHONPATH override from remotefilelog tests They were added in https://bitbucket.org/facebook/hg-experimental/commits/fdcad37a6a68cfbaf5920f3eeaa0cc9cae42bd26, which says this: When remotefilelog moved from its own repo, the tests needed to be updated to adjust the PYTHONPATH to ensure the in-repo remotefilelog was loaded instead of the system one. This meant any local runs of remotefilelog tests would've been using the system remotefilelog unless the user had manually set the PYTHONPATH themselves. That doesn't seem relevant with remotefilelog in core. Differential Revision: https://phab.mercurial-scm.org/D5248

tests: drop obsolete "hginit" alias in remotefilelog tests Differential Revision: https://phab.mercurial-scm.org/D5247

fix: add extra field to fixed revisions to avoid creating obsolescence cycles The extra field prevents sequential invocations of fix from producing the same hash twice. Previously, this could cause problems because it would create an obsolescence cycle instead of the expected new successor. This change also adds an explicit check for whether a new revision should be committed. Until now, the code relied on memctx.commit() to quietly do nothing if the node already exists. Because of the new extra field, this no longer covers the case where we don't want to replace an unchanged node. Differential Revision: https://phab.mercurial-scm.org/D5245

cleanup: use revision numbers instead of hashes in test output This allows changes to the hashes produced by fix to not needlessly modify this area of the test. Differential Revision: https://phab.mercurial-scm.org/D5244

tests: make the commands.resolve.confirm tests not pollute the test-wide hgrc I want to add tests after these tests that create a new repo and use it, and was confused for a bit as to why they were seeing different behavior than I expected.

tests: fix a couple typos in test-resolve.t comments and add a comment Differential Revision: https://phab.mercurial-scm.org/D5241

fix: add suboption for configuring execution order of tools This could be accomplished by using wrapper scripts, but that would diminish the usefulness of the incremental formatting logic. Configuring execution order along with other things in the hgrc is probably more convenient anyway. This change highlights some awkwardness with suboptions and default values, which should be addressed separately. Differential Revision: https://phab.mercurial-scm.org/D5237

tests: fix up some import statements caught by Python 3 I'm curious how the import checker manages to be so much more pedantic in Python 3, but not enough to bother exploring. Differential Revision: https://phab.mercurial-scm.org/D5240
