evolve: replace each obsolete sha1 in the description with its latest successor Obsolete csets are hidden by default and don't get pushed to the parent repo. In order to avoid broken references in commit messages, it makes sense to evolve those references to the latest and greatest successor, as each cset containing them is evolved. Of course, stale references can still occur if a commit in branch 'A' references something in branch 'B', and that something in 'B' is evolved but 'A' isn't subsequently evolved. This alleviates the user that is evolving a series of commits from having to 1) recognize that there is a hash that needs updating in any one of the series 2) look up the latest successor manually 3) hg amend -e The regular expression for matching and the logic for replacing are borrowed from the convert extension [1]. It might be nice for the output to state the reason that the reference couldn't be updated (it was pruned, split or diverged), but that may be excessive for something only displayed in verbose mode. (Maybe it should be a ui.status() instead?) [1] http://selenic.com/hg/rev/45562379ce4e

test: add parent hash to commit message in test-evolve.t This (slightly) reduces the changes to the test when hashes in the commit message are evolved in the next commit.

evolve: fix the 'grab' alias to work on Windows For some reason, the variable wasn't substituted on Windows in this case. From the test suite: $ hg grab 8 '' is not recognized as an internal or external command,\r (esc) operable program or batch file.\r (esc) This change seems hacky, but there isn't a readily available example of setting up a shell alias like this from a python module to know if there is a better way, and it seems like this is maybe just a convenience for tests, since there is no documentation for the aliases. The local copy of run-tests.py appears to predate the Windows support in the Mercurial repository's version, and fails each test with: The system cannot find the path specified. However, with this change and blacklisting test-simple4server.t, the tests can (mostly) be run on Windows like so: $ ../../hg/tests/run-tests.py --with-hg=../../hg/hg --blacklist windows Skipped test-simple4server.t: blacklisted Warned test-obsolete.t: no result code from test Warned test-tutorial.t: no result code from test Warned test-evolve.t: no result code from test Warned test-userguide.t: no result code from test Warned test-sharing.t: no result code from test Warned test-drop.t: no result code from test Failed test-prune.t: output changed # Ran 41 tests, 1 skipped, 6 warned, 1 failed.
