stablerangecache: sanity check subranges Try to detect invalid conditions on insert as would result in deep recursions and final aborts much later. This has been observed on two different machines and the check makes it hopefully possible to find the origin of the problem.

obslog: use unfiltered repo for --no-graph implementation too repo.unfiltered() is used for graph version of obslog, because if we want to filter non-local changesets, we only have to provide --filternonlocal flag on the command line and _nodesandmarkers() will handle filtering. But that means for obslog without -f to work correctly we need to provide unfiltered repo to that function. With this patch both implementations of obslog (--graph and --no-graph) see the same repo.

tests: don't assume that echo will unescape \\

tests: avoid non-portable sed command sed -i is a GNU extension and the i command without newline as well. Just create the file from scratch with printf to side-step the issue.

tests: check for file existance in a portable way The precise output of ls is highly OS specific, so just use the simpler test command.

tests: deal with "ls" vs "ls -A" difference on 2BSD derived systems ls on 2BSD derived systems historically defaults to -A for root, so use it unconditionally for consistent results.

tests: silence potential warnings about uname -o The option is not supported on the BSDs, but also not relevant as it is only used to detect msys.

evolve: remove unused divergenceflag and splitflag of MultipleSuccessorsError

evolve: consider all obsolete ancestors when finding new parent for orphan Both the old and the new logic have in common that the orphan changeset is moved to the tipmost successor of one or more ancestors of the orphan changeset. The previous logic considered only the first non-pruned ancestor of the orphan changeset. The new logic considers all obsolete ancestors of the orphan changeset. The logic in _possibledestination() had to be changed to be consistent with the new logic.

py3: fix debugstablerangecache

topic: provide cache to successorssets() in _singlesuccessor() Since we're using obsutil.successorssets() in a loop, it may help performance to have cache.

obslog: support --all with --no-graph

obslog: support --filternonlocal with --no-graph

obshistory: restructure templates a bit, drop default verb ("pruned") We always have a verb provided to the templates now, this should be fine.

obshistory: prepare data for displaymarkers() in a separate function

obshistory: make patchavailable() handle predecessors too

tests: make sure not to test the same thing twice A block under this one already tests obslog --no-graph with -f. Right now there's no difference in output, but maybe some day obslog --no-graph will actually support --filternonlocal.

obshistory: rename precursors to predecessors in displayrevs()

obshistory: rename _debugobshistorydisplaymarker() to displaymarkers() Apart from the obvious change, the function now can show multiple markers, not just one.

obshistory: rename graph/revs-displaying functions Same idea as the previous patch, but with a "display" prefix.

obshistory: rename node/ctx-displaying functions Not just for debug, and yes we know it's obshistory-related.

branching: merge with stable

topic: use generationssubrel less directly, because it was recently renamed

auto-publish: issue the capabilities in all cases It seems better to message client that we support the capabilities in all cases.

packaging: add an entry to debian/changelog mentioning the previous change

packaging: bump minimum required version of mercurial in debian/control

[debian] package 9.3.1-3 for bionic ubuntu

tests: update output to match 1b8fd4af3318 in core CORE-TEST-OUTPUT-UPDATE: 1b8fd4af3318
