util: whitelist apfs for hardlink support Seems to work fine for me. Differential Revision: https://phab.mercurial-scm.org/D3134

mq: avoid a silly conversion from binary nodeid to hex We generally deal with binary nodeids in code. In this case the hex nodeid was passed to strip.checksubstate() where it was passed to repo.__getitem__, which of course accepts a binary nodeid.

narrow: remove unused "cacheprop" stuff This is unused since D3046. I didn't even notice it then, but tests still pass so I hope it's still handled safely. Differential Revision: https://phab.mercurial-scm.org/D3142

tests: disable infinitepush tests for simple store Infinitepush relies heavily on bundles and bundlerepo. As such, it won't be easy to make compatible with alternate storage backends at this time. Let's disable the tests when running with our simple store. Differential Revision: https://phab.mercurial-scm.org/D3062

rebase: remove unnecessary and incorrect handling of nullid We used to write a nullid as hex to the rebase state file and interpret it as the "todo" state (value -1). However, when reading it, we compared the string value to (binary) nullid, which would of course not match. AFAICT, it still worked because when the read nodeid did not match nullid (which, again, it didn't), we'd use the normal path which did repo[<hex nullid>].rev(), and that also happens to return -1. It seems to have been this way ever since 9972758ab4c5 (rebase: handle revtodo as a special value when storing/restoring state, 2014-12-02).

rebase: convert "oldrev" to revnum earlier It was done in 3 places before, now just 1. Differential Revision: https://phab.mercurial-scm.org/D3139
