context: skip path conflicts by default when clearing unknown file (issue5776)
Prior to adding path conflict checking in 989e884d1be9, the test-audit-path.t
tests failed as shown here (but it was globbed away). 989e884d1be9 made it fail
with a message about the destination manifest containing a conflict (though the
no-symlink case wasn't updated). When the path conflict checking was gated
behind an experimental config in 2a774cae3a03^::2a774cae3a03, the update started
erroneously succeeding here. It turns out that the child of 989e884d1be9 is the
origin of this change when path conflict checking is disabled, as shown by
grafting the experimental config range on top of it.
What's happening here is merge.batchget() is writing the symlink 'back' to wdir
(but as a regular file for the no-symlink case), and then tries to write
'back/test', but calls wctx['back/test'].clearunknown() first. The code that's
gated here was removing the newly written 'back' file, allowing 'back/test' to
succeed. I tried checking for the dir components of 'back/test' in dirstate,
and skipping removal if present. But that didn't work because the dirstate
isn't updated after each file is written out.
This is the last persistent test failure on Windows, so the testbot should start
turning green now. \o/

Testing head checking code: Case A-1
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category A: simple case involving a branch being superceeded by another.
