mercurial: Changelog

hgweb: implement json-graph It's essentially a copy of json-log with graph-related things added (col, row, color, edges).

rebase: replace --inmemory flag with rebase.experimental.inmemory config Differential Revision: https://phab.mercurial-scm.org/D1666

tests: add some commentary and diagnostics to test-run-tests.t Hopefully this will give us a shot at fixing it on the Windows builder. Differential Revision: https://phab.mercurial-scm.org/D1653

templater: fix "one arguments"

tests: add commit hashes to log commands in rebase tests Commit hashes are a useful way to ensure the content of commits made in the tests are not changing, even if we don't query every aspect of every commit. (And some properties, like extras, are rarely printed at all.) Many of the rebase log -G calls didn't show hashes; by adding hashes to places that weren't showing them we can help protect those tests from unwanted changes. Differential Revision: https://phab.mercurial-scm.org/D1650

tests: add a simple test for in-memory rebase This is just a very simple start, but verifies some of the basic cases of an in-memory rebase. Differential Revision: https://phab.mercurial-scm.org/D1652

patch: do not break up multibyte character when highlighting word This changes {\W} to {\W - any 8bit characters} so that multibyte sequences are taken as words. Since we don't know the encoding of user content, this is the most sensible definition of a non-word.

run-tests: accept '\' vs '/' path differences without '(glob)' Having to constantly adjust these is a hassle. It's easy for this to slip by when not testing on Windows, and then when it happens on stable, the tests fail for the next 3 months if we follow the rules for stable. This works the same way the EOL differences are ignored, namely to adjust on the fly and recheck on Windows. I can't think of any situation where there would be a '\' on Windows, a '/' elsewhere, and the '/' should be considered a failure on Windows. This fixes the obvious output problems where (glob) is missing. Without this, test-alias.t, test-remotenames.t and test-largefiles-misc.t are failing. The flip side (not handled by this) is the case where an unnecessary glob is present. There seems to be two separate behaviors. cf300c1ad7bf is an example of where the test has been autocorrecting (with output differences), and d4ec69ff652a is an example where the test fails and reports 'no result code from test'. Hopefully those cases will become even more rare if people don't need to guess at when a glob is needed for a Windows path. It's probably unreasonable to submit a single patch that wipes out all of the (glob) instances that were only used to hide path differences, given the churn from other contributors. Since their presence isn't harming the tests, these can be removed through attrition.

run-tests: suggest a (glob) for os.path.sep mismatches with '\r\n' EOL too We already do this for lines ending in '\n', such that the test only needs to be run with --interactive and the changes accepted at the end. But that wasn't working with list-tree.py output for example, and required manual fixup.
