evolve: add pre-check logic for content-divergence in rewriteutil.precheck() For now, pre-check will abort if rewriting a rev create divergence (and config experimental.evolution.allowdivergence is not set to True). But this behaviour can be improved where instead of abort maybe we can confirm the user to either proceed with divergence or some other options depends on what command user is running. Changes in test file are used to overrides the pre-check for testing purpose (using experimental.evolution.allowdivergence=yes).

topic: make in-memory rebase preserve topic The override code thought that `__init__` would return the runtime instance, but it's actually the first argument to the function (the `self` argument), so the code had no effect at all before this patch. I think the bug only affected in-memory rebase because the in-working-copy rebase used the current topic, which was set correctly since 5156a67f66a6 (topics: update current topic to the topic of newly rebased commit (issue5551), 2017-06-29).

Temporary commit for time measurement of test file + pandoc

ci: Add CI job for building the documentation

tutorial: compile the tutorial in rst so it can be included

tutorial: run the tutorial test file to update to latests ui messages

ignore: fix hgignore to point to the correct folder Files might have been imported initially as docs/training but were moved to docs/tutorial and the hgignore was likely forgotten.

stack: rename stack.revs into stack.indexedrevs They are accessible by an index, and are sorted. But they don't include all revisions for show in showstack().

stack: return from behindcount() early Reduces indentation.

stack: use self._revs in stack.behindcount() This code also doesn't care about the order of revisions, it just wants all revs except stack base, and that's what self._revs is.

stack: use self._revs in stack.heads() No code cares about the ordering of the heads anyway, so let's use the unordered property that doesn't need to be sliced (because it doesn't include base).

pick: Add a test to check that pick pick the right content

WIP on handling stacks

test: add a test for current behavior of precursors revset The precursors revset currently returns the closest predecessors of a revset. If these predecessors are not known locally, it returns an empty list.
