phabricator: add the "Changes Planned" status name I noticed this when coloring the status output. But it looks like status names are also used in the pseudo revset language as well, and abort when parsing a name not in this list. Differential Revision: https://phab.mercurial-scm.org/D7607

cext-revlog: fixed __delitem__ for uninitialized nodetree This is a bug in a code path that's seldom used, because in practice (at least in the whole test suite), calls to `del index[i:j]` currently just don't happen before the nodetree has been initialized. However, in our current work to replace the nodetree by a Rust implementation, this is of course systematic. In `index_slice_del()`, if the slice start is smaller than `self->length`, the whole of `self->added` has to be cleared. Before this change, the clearing was done only by the call to `index_invalidate_added(self, 0)`, that happens only for initialized nodetrees. Hence the removal was effective only from `start` to `self->length`. The consequence is index corruption, with bogus results in subsequent calls, and in particular errors such as `ValueError("parent out of range")`, due to the fact that parents of entries in `self->added` are now just invalid. This is detected by the rebase tests, under conditions that the nodetree of revlog.c is never initialized. The provided specific test is more direct.

filemerge: drop a default argument to appease pytype The function slices and takes the length of this argument without internally setting it if not provided. There was no bug here because both callers passed the argument. Differential Revision: https://phab.mercurial-scm.org/D7464

fuzz: add a seed corpus for the dirs fuzzer I was hoping to trigger an asan violation under Python 3 that some internal tests at Google found, but for some reason that's beyond me I can't seem to manage. Differential Revision: https://phab.mercurial-scm.org/D7600
