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.
