import: make help clearer. suggested by asak.

mq: fix qparents to return the correct parent when no patches are applied

mq: hg qnew -f should refresh the new patch qnew -f was originally meant to just skip the localchanges check. But, it currently discards the local changes, which is not at all what people expect. This patch changes qnew -f to create the new patch and then run hg qrefresh on it. The local changes will be in the new patch.

merge with crew.

merge with wsgi changes.

Put support for persistent connections back in.

Fix two small bugs that would've prevented the web interface and IPv6 from working.

This patch make several WSGI related alterations. First, it changes the server to be almost a generic WSGI server. Second, it changes request.py to have wsgiapplication and _wsgirequest. wsgiapplication is a class that creates _wsgirequests when called by a WSGI compliant server. It needs to know whether or not it should create hgwebdir or hgweb requests. Lastly, wsgicgi.py is added, and the CGI scripts are altered to use it to launch wsgiapplications in a WSGI compliant way. As a side effect, all the keepalive code has been removed from request.py. This code needs to be moved so that it is exclusively in server.py

Fix server to set up a more WSGI compliant environment.

import: parse email messages

Don't require opts['dry_run'] to be set to fix external tools like tailor.

Allow using default values with ui.configlist, too, and add a test for this.

Make "[web] allow_push, deny_push" and "[http_proxy] no" use ui.configlist.

Fixed [web] allow_archive for comma separated parameters by using ui.configlist. Changed tests/test-archive to use allow_archive instead of the deprecated allowzip, allowgz and allowbz2.

Added ui.configlist method to get comma/space separated lists of strings. For example: users = alice, bob colors = red green blue

Fix ui.expandpath problem and broken test introduced by 4a2a4d988ead.

do not try to package lsprof if not available.

add test for default-push.

push, outgoing, bundle: fall back to "default" if "default-push" not defined

print message after backout that tells that backout adds new head.

Test case for #295

Fix localrepo.changes() Correctly decide if we are diffing the working dir

Change revlog.heads to walk the revision graph using revision numbers On the kernel repo: $ hg heads -q before after RevlogNG 1.11 0.52 Revlogv0 0.80 0.69 Since the current code for tags has to find all the heads of the repo, this also helps there: $ hg tags before after RevlogNG 2.35 1.76 Revlogv0 2.04 1.90

Add revlog.parentrevs function. This allows one to walk the revision graph using only revision numbers, which can be faster than using revision hashes, especially for RevlogNG, where the parents of a revision are stored as revision numbers.

mq: add qimported patches if patch dir is a repo
