context: delete mistaken comment about return value of renamed() The comment seems to think that the return value of renamed() is a tuple of source pathsx in the parents, but it's actually a pair of (rename source path, file nodeid). Differential Revision: https://phab.mercurial-scm.org/D5639

copies: get working copy parents from wctx, not dirstate, to make in-mem work Before this patch, `run-tests.py test-rebase-conflicts.t --extra-config-opt rebase.experimental.inmemory=1` would have some lines that say "searching for copies back to rev 3" changed to "... rev 1". I don't know of a better way of testing this patch than doing that manually. There are many other differences, so we're not ready to use #testcases syntax on the entire test-rebase-conflicts.t yet.

copies: pass contexts into _findlimit() Just a little refactoring to make the next patch simpler. Differential Revision: https://phab.mercurial-scm.org/D5595

copies: consider nullrev a common ancestor I've seen many bugs in the git codebase that were caused by it not having a null revision and being forced to treat root commits differently. Mercurial has a null revision and I think it's generally a bug to treat it differently from other commits in graph algorithms. This effectively undoes 83cfa1baf8ad (copies: don't report copies with unrelated branch, 2010-01-01). The test cases that that commit added still passes. I suspect some other fix after that commit made it unnecessary. Differential Revision: https://phab.mercurial-scm.org/D5594

py3: new tests from the ratchet Thanks to indygreg for doing the work on these! Differential Revision: https://phab.mercurial-scm.org/D5705

dagop: check if stopdepth is greater than or equal to maxlogdepth Might prevent off-by-one errors.

revset: move dagop.maxlogdepth usage to generationsrel() Not all subscript operations would want (maxlogdepth - 1) in place of None.

test-revset: check that #generations[1:-1] doesn't result in any errors

py3: fix a bytes/str mingling in test-install.t

tests: conditionalize Windows difference in test-dispatch.t The output matches the comment added 6 years ago in ef60083b5536, so I'm assuming that difference was the reason for the over-globbing removed in 93a7539a546e. There's still a bit of py3 instability here, but I assume those are just more Windows issues: @@ -95,7 +95,7 @@ [255] $ hg log -b --cwd=inexistent default - abort: $ENOENT$: 'inexistent' + abort: $ENOENT$: inexistent [255] $ hg log -b '--config=ui.traceback=yes' 2>&1 | grep '^Traceback' @@ -189,7 +189,7 @@ $ hg -R a archive '' abort: $ENOENT$: '' (no-windows !) - abort: $ENOTDIR$: '' (windows !) + abort: $ENOTDIR$ [255] #if no-outer-repo

util: cast memoryview to bytes Python 3 uses readinto() instead of read() in places. And taking a slice of the buffer passed to readinto() will produce a memoryview. _writedata() then gets confused when testing for `b'\n' in data` because memoryview is an iterable over ints instead of 1 character bytes. We work around by casting a memoryview to bytes. Differential Revision: https://phab.mercurial-scm.org/D5704

tests: add b'' prefixes to ui.configbool() call Otherwise the call fails due to using str on Python 3. # skip-blame: just b'' prefixes Differential Revision: https://phab.mercurial-scm.org/D5703

commands: check for modheads being None Python 2 allows the > operator to be used with a None and an int. Python 3 does not. So we need to ensure the value isn't None before comparing with >. Differential Revision: https://phab.mercurial-scm.org/D5702
