phase: report number of non-public changeset alongside the new range When interacting with non-publishing repository or bundle, it is useful to have some information about the phase of the changeset we just pulled. This changeset updates the "new changesets MIN:MAX" output to also includes phases information for non-public changesets. Displaying extra data about non-public changesets means the output for exchange with publishing repository (the default) is unaffected.

tests: disable test-nointerrupt on Windows Per the followup discussion[1]. proc.send_signal(INT) in timeout.py raises a ValueError because of an unsupported signal. I don't like missing test coverage for this on Windows. But this is the last test failing on Windows, and red all the time hides new failures. [1] https://phab.mercurial-scm.org/D3716

tests: conditionalize an error message about unlinking a non empty directory The message on Windows comes from win32.unlink(). It looks like os.unlink() on posix platforms is a simple call to unlink(3), which turns into unlinkat(2). Since there's a comment in one of the tests that the message should be improved, I don't think it's worth adding a check in win32.unlink() to see if it's empty, if that function is always going to fail on a directory. (It seems like the POSIX spec allows unlinking directories though.)

ancestors: add nullrev to set from the beginning Differential Revision: https://phab.mercurial-scm.org/D4507

ancestor: filter out initial revisions lower than stoprev

ancestor: add test showing inconsistency between __iter__ and __contains__

ancestors: ensure a consistent order even in the "inclusive" case It seems odds to first issue the "source" revs and then the other ancestors. In addition, doing so can break the other contract of always issuing a child before its parent. We update the code to apply the same logic to all yielded revision. No tests break so we seem in the clear except where we explicitly test the order.

ancestors: actually iterate over ancestors in topological order (issue5979) This code previously used a dequeue logic, the first ancestors seen were the first ancestors to be emitted. In branching/merging situations, it can result in ancestors being yielded before their descendants, breaking the object contract. We got affected by this issue while working on the copy tracing code. At about the same time, Axel Hecht <axel@mozilla.com> reported the issue and provided the test case used in this changeset. Thanks Axel. Running `hg perfancestors` does not show a significant difference between the old and the new version.

doc: use modern import style in runrst

hgweb: do not audit URL path as working-directory path Since hgweb is an interface to repository data, we don't need to prohibit any paths conflicting within the filesystem. Still an access to working files is audited by filectx.
