typing: ensure that error.Abort is given bytes There's a bunch more typing to be done here, but the list of things to fix is already long, and I know there are instances where this is being used incorrectly. Differential Revision: https://phab.mercurial-scm.org/D10166

typing: fix a suppression directive that was mangled by black formatting It looks like black is moving comments needed by pytype out of position, and causing some things that should be disabled to be enforced anyway. Differential Revision: https://phab.mercurial-scm.org/D10165

commit: reorder if-else conditional to give mergestate info priority Looking at the code now, I was unable to find a good reason as why we only rely on mergestate extras info after checking whether a filelog parent is ancestor of other or not. I mean if we have stored in mergestate that `other` was chosed, we should blindly pick that one. This cleanup will also help introduce more cases when both `fparent1` and `fparent2` are non-null but using info from mergestate, we can fastpath. The test change actually demonstrates the point of the patch. During merge we were getting the other side of the file but on commit we were marking that as merged.

enclink: check contents of symlinks not just size in case of fcrypt Check content of symlinks because st_size may indicate the size of encrypted data which does not match actual link value. Differential Revision: https://phab.mercurial-scm.org/D10146

rebase: inline simple function for finding obsolete subset of commits `_filterobsoleterevs()` is just one line long. It was introduced in 2d294dada4f8 (rebase: small refactoring to allow better extensibility from extensions, 2016-01-14), for use by the "inhibit" extension. That extension was removed from the evolve repo in 87e87881059d (compat: drop the inhibit hacky extension, 2017-10-24). Differential Revision: https://phab.mercurial-scm.org/D10198

ci: hook network-io tests into the pipeline This runs the "pip install" tests once for Python 2 and 3 each. Differential Revision: https://phab.mercurial-scm.org/D10075

merge: with stable

test: update expected output in test-http.t The output was introduced in a4c19a162615 and is wrong and unstable. So we glob it as other part of these tests already do. Differential Revision: https://phab.mercurial-scm.org/D10153

remotefilelog: remove unused import This is no longer used since a4c19a162615. Differential Revision: https://phab.mercurial-scm.org/D10152

wireprotov1peer: don't raise internal errors in some cases Specifically, when the peer is closed in the middle of a batch of rpcs. Differential Revision: https://phab.mercurial-scm.org/D10074

sshpeer: don't fail forwarding output from closed connections The test still shows an internal error, but one that happens further along. Differential Revision: https://phab.mercurial-scm.org/D10073

test: show internal exception with batchable rpcs over ssh Differential Revision: https://phab.mercurial-scm.org/D10072

rhg: Ignore trailing newlines in .hg/sharedpath Differential Revision: https://phab.mercurial-scm.org/D10132

tests: Add `--rhg` and `--with-rhg=<path>` options for `run-tests.py` They are mostly equivalent to the corresponding `chg` options. For now, many tests are still failing in this configuration. It is *not* run on CI. Differential Revision: https://phab.mercurial-scm.org/D10095
