grep: don't search past the end of the searched string '*' causes the resulting RE to match 0 or more repetitions of the preceding RE: >>> bool(re.search('.*', '')) >>> True This causes an infinite loop because currently we're only checking if there was a match without looking at where we are in the searched string.

convert: fix a too-long line nag

convert: add support for converting git submodule (issue3528) Previously, convert aborted upon encountering a git submodule. This patch changes it so that it now succeeds. It modifies convert_git to manually generate '.hgsub' and '.hgsubstate' files for each git revision, so as to convert git sub modules to non-mercurial subrepositories.

run-tests.py: remove runqueue's results parameter since it is now a global

makefile: don't use system hgrc when running hg in-place This suppresses the printing of spurious error messages if a global hgrc refers to extensions that the in-place hg can't access.

setup: print subprocess stderr if there is any I just spent 1.5 days trying to debug a failing buildbot because setup.py was silently dropping the errors that were being printed by in-place hg.

run-tests: open child-parent pipes in binary mode Python's pickle is a binary format.

amend: force editor only if old message is reused (issue3698) This regression was added by 9732473aa24b. It triggered the editor even if --message or --logfile were provided.

grep: don't search past the end of the searched string '*' causes the resulting RE to match 0 or more repetitions of the preceding RE: >>> bool(re.search('.*', '')) >>> True This causes an infinite loop because currently we're only checking if there was a match without looking at where we are in the searched string.

bookmarks: introduce a bmstore to manage bookmark persistence Bookmarks persistence still showed a fair amount of its legacy as a monkeypatching extension. This encapsulates all bookmarks serialization and parsing in a single class, and offers a single location where other bookmarks storage engines can be substituted in. As a result, many files no longer import the bookmarks module, which strikes me as an encapsulation win. This doesn't do anything to the current bookmark state yet, but I'm hoping put that in the bmstore class as well.

run-tests: add --time option to log times for each test --time also prints out the wall-clock time each test takes in descending order.

run-tests: remove resultslock since it serves no useful purpose Each child process has its own copy of the results dict, so all access to the results dict is serial.

run-tests: use pickle to send results from children to parent JSON would probably be preferable, but it isn't available for Python 2.4 or 2.5.

bookmark: remove useless line in `validdest` This case is already covered by the `if old == new:` conditional at the start of the function.

bookmark: issue a single call to `allsuccessors` per loop Update to this code was minimalist when `allsuccessors` argument were changed from a list to a set. As this code is getting my attention again I realised we can drastically simplify this part of the code by issue a single call to `allsuccessors`.
