py3: whitelist another 3 tests caught by the ratchet Differential Revision: https://phab.mercurial-scm.org/D4069

testrunner: allow multiple #testcases This lets you have multiple #testcases declarations and they're taken to be different dimensions of the test, so their cross product becomes the total set of test cases. For example: #testcases obsstore-on obsstore-off #testcases manifest-flat manifest-tree $ hg rebase ... ... #if obsstore-on $ hg log ... #endif Note that this is an excellent way to slow down the test suite, so use it with care. The feature is implemented by replacing most of the "case" variables that were strings before by an array of strings with each item a different dimension of the test case. The file names are created by joining the dimensions by "#" (e.g. test-foo.t#obsstore-on#manifest-flat). Differential Revision: https://phab.mercurial-scm.org/D4049

testrunner: use "#" for "test cases" suffix in .err filename too This seems like a natural follow-up to b865bba56db1 (run-tests: update the test case name format, 2018-05-13). Differential Revision: https://phab.mercurial-scm.org/D4052
