hg: raise Abort on invalid path...
hg: raise Abort on invalid path Currently, some os.path functions when opening repositories may raise an uncaught TypeError or ValueError if the path is invalid. Let's catch these exceptions and turn them into an Abort for convenience. Differential Revision: https://phab.mercurial-scm.org/D5772

# produces two repositories with different common and missing subsets
#
# $ discovery-helper.sh REPO NBHEADS DEPT
#
# The Goal is to produce two repositories with some common part and some
# exclusive part on each side. Provide a source repository REPO, it will
# produce two repositories REPO-left and REPO-right.
#
# Each repository will be missing some revisions exclusive to NBHEADS of the
# repo topological heads. These heads and revisions exclusive to them (up to
# DEPTH depth) are stripped.
#
# The "left" repository will use the NBHEADS first heads (sorted by
# description). The "right" use the last NBHEADS one.
#
# To find out how many topological heads a repo has, use:
#
# $ hg heads -t -T '{rev}\n' | wc -l
#
# Example:
#
# The `pypy-2018-09-01` repository has 192 heads. To produce two repositories
# with 92 common heads and ~50 exclusive heads on each side.
#
# $ ./discovery-helper.sh pypy-2018-08-01 50 10
