log: fix order of revisions filtered by multiple OR options (issue5100) This is the simplest workaround for the issue of the ordering of revset, which is that the expression "x or y" takes over the ordering specified by the input set (or the left-hand-side expression.) For example, the following expression A & (x | y) will be evaluated as if (A & x) | (A & y) That's wrong because revset has ordering. I'm going to fix this problem in the revset module, but that wouldn't fit to stable. So, this patch just works around the common log cases. Since this change might have some impact on performance, it is enabled only if the expression built from log options has ' or ' operation.

demandimport: add _imp to ignore list Mozilla is seeing an issue with demand importing of _imp failing in pkg_resources/__init__.py:fixup_namespace_packages. It strangely only reproduces when using a modern version of setuptools/pip in certain scenarios. Adding _imp to the demand import ignore list seems to make the problem go away.

tests: rename regression tests

zeroconf: fix crash in "hg paths" when zeroconf server is up Running "hg paths" with zeroconf enabled and when a zeroconf server is up and running gives a traceback with "ValueError: rawloc must be defined". This is because zeroconf needs to wrap ui.configsuboptions(), introduced in dccbebcff075.

zeroconf: fix setsockopt() call on Solaris to send payload of correct length The zeroconf extension has been broken on Solaris since the beginning, but no one noticed until the testsuite started poking it after changeset 72f2a19c5f88, when it started running "hg paths" with the extension enabled. Solaris requires that, for IP_MULTICAST_{TTL,LOOP}, the argument passed in be of length 1. With the original code here, it gets passed in as an int -- length 4 -- and so the system call fails with EINVAL. Thankfully, Python's socket.setsockopt() allows you to pass in a string instead of an integer, and it passes that string to libc's setsockopt() with the correct value and length.

blackbox: properly replace ui class Without this, anyone creating a ui object using: uimod.ui() skips the blackbox. Also, anyone doing ui.copy() skipped the blackbox. Unfortunately, the ui object lifestyle is a bit messy, the first one that's created is never actually initialized with subclasses, instead pieces of the subclass are adopted into the primal ui object. In order to handle this, a _partialinit method will be called to ensure that the blackboxui is properly initialized.
