testing: expand Hypothesis tests with branch commands This builds on the previous work to add Hypothesis based stateful testing to add branching commands to the model.

testing: generate tests operations using Hypothesis The idea of this patch is to expand the use of Hypothesis within Mercurial to use its concept of "stateful testing". The result is a test which runs a sequence of operations against a Mercurial repository. Each operation is given a set of allowed ways it can fail. Any other non-zero exit code is a test failure. At the end, the whole sequence is then reverified by generating a .t test and testing it again in pure mode (this is also useful for catching non-determinism bugs). This has proven reasonably effective at finding bugs, and has identified two problems in the shelve extension already (issue5113 and issue5112).

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.

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.

blackbox: store the blackbox ui object instead of the log file Without this, the last logged entry didn't have access to the repository, and thus couldn't report its version (and especially that an add or similar dirtied it). A side-effect is that one repo leaks until process exit...
