revset: narrow scope of "except ParseError" block in _parsealiasdecl() This helps to factor out a common function. "if True" will be removed soon.

obsstore: move delete function from obsstore class to repair module Since one of the original patches was accepted already and people on the mailing list still have suggestions as to how this should be improved, I'm implementing those suggestions in the following patches (this and the ones that might follow).

debugobsolete: style fixes to debugobsolete that slipped from original commit

import: document --exact behavior in more detail

util: add doctest to datestr()

date: fix boundary check of negative integer

chg: server exited with code 0 without being connectable is an error Before this patch, if the server started by chg has exited with code 0 without creating a connectable unix domain socket at the specified address, chg will exit with code 0, which is not the correct behavior. It can happen, for example, CHGHG is set to /bin/true. This patch addresses the issue by checking the exit code of the server and printing a new error message if the server exited normally but cannot be reached.

shelve: refactor directory name into constant Shelve directory name extracted into constant to avoid typos/duplication.

pycompat: switch to util.stringio for py3 compat

py3: use multi-line import in test-wireproto.py The reason I did it is that I had a later commit that was adding to the list.
