mq/qqueue: commonalise the queue deletion code

mq: don't inherit default and default-push paths with --mq (issue2333) Configuration from the outer repo is inherited to the patches repo when --mq is used. In case the patches repo only has paths.default configured but the outer repo has paths.default-push then the inherited default-push will win. Very confusing. Inheriting the default paths is however wrong in all sane cases, so now we explicitly remove them.

test-subrepo-paths: use printf instead of echo Different shells have different opinions on how to backslashes must be escaped for echo, but printf is consistent across zsh, dash, bash, tcsh, and csh.

parendelta: fix computation of base rev (fixes issue2337) Refactor revlog._addrevision() and put the correct base rev in the parent-delta case: base(rev) should always be equal to the first full snapshot that is needed by the delta chain, in both parent-delta and tip-delta case. Before this fix, the base rev was in most case wrong (and in the case where p1 == nullid, this triggered the bug from issue2337). This means that repositories converted to parent-delta earlier are corrupted and needs to be reconverted.

revlog._addrevision(): make the parent of the cached delta explicit

subrepos: handle backslashes in subpaths

help: document stringify templatefilter

test-subrepo-paths: moved comment lines to where they belong

hgfixes: added a fixer to convert changes in the email package This patch adds a fixer that accounts for changes in python packages, as the framework provided by lib2to3 is only able to track changes in module names. This fixer (hopefully) can fix any change in one-level hierarchies. To exemplify, this fixer can successfully change an import from "email.MIMEMultipart" to "email.mime.multipart".

contrib/setup3k.py: added script to build hg with py3k This patch implements a script that inherits most of its functionality from hg's setup.py and adds support to calling 2to3 during invocation with python3. The motivation of having this script around is twofold: 1) It enables py3k crazies to test mercurial in py3k and, hopefully, patch it more easily, so it can improve the py3k support to eventually run there. 2) Being separated from the main setup.py eliminates the need to make hg's setup.py even more cluttered, and enables "independent" development until the port is done. Some considerations about the structure of this patch: Mercurial already overrides the behavior of build_py, this patch tweaks it a bit more to add support to call 2to3 with a custom fixer* location for Mercurial. There is also a need of having the core C modules built *before* the translation process starts, otherwise 2to3 will think those are global modules. * A fixer is a python module that transforms python 2.x code in python 3.x code.

mq: save qrefresh message for easy recovery in case it fails (issue2062) Currently, if you start editing a commit message from qrefresh -e and, for any reason: forget you were editing it, leave the editor open and start qpopping and qpushing, when you decide to save your commit message, it is going to fail. This patch copies the commit behavior of saving the message contents in $HGROOT/.hg/last-message.txt before continuing.

util: avoid using hashlib on Python < 2.5 (issue2278) The following patch allows the use of python2.4 with a standalone hashlib rather than assuming that python2.5 is in use when hashlib is imported successfully.

ui: differentiate empty configlist from None

revset: predicate to avoid lookup errors A query like head() and (descendants("bad") and not descendants("fix")) (testing if repo heads are affected by a bug) will abort with a RepoLookupError if either badrev or fixrev aren't found inside the repository, which is not very informative. The new predicate returns an empty set for lookup errors, so head() and (descendants(present("bad")) and not descendants(present("fix"))) will behave as wanted even if those revisions are not found.

inotify: show the exact command used to start the server

demandimport: store level argument on _demandmod instances The 'level' argument to __import__ was added in Python 2.6, and is specified for either relative or absolute imports. The fix introduced in e160f2312815 allowed such imports to proceed without failure, but effectively disabled demandimport for them. This is particularly unfortunate in Python 3.x, where *all* imports are either relative or absolute. The solution introduced here is to store the level argument on the demandimport instance, and propagate it to _origimport() when its value isn't None. Please note that this patch hasn't been tested in Python 3.x, and thus may not be complete. I'm worried about how sub-imports are handled; I don't know what they are, or whether the level argument should be modified for them. I've added 'TODO' notes to these cases; hopefully, someone more knowledgable of these issues will deal with them.

revert: use opts.get If you want to programatically perform a revert right now you need to include a date=False parameter due to the use of opt["date"] instead of opt.get("date").
