svnwrap: fix handling of quotable URLs (fixes #197, refs #132)
The way hgsubversion handles URLs that may or may not be quoted is
somewhat fragile. As part of fixing issue 132 in 925ff8c5989c, the
path component of URLs was always quoted. The URL has been attempted
encoded since the initial check-in.
The fix from 925ff8c5989c was incomplete; reverting it allows us to
clone a URL with a '~' in it.[1] Encoding the URL as UTF-8 seldom
works as expected, as the default string encoding is ASCII, causing
Python to be unable to decode any URL containing an 8-bit
character.
The core problem here is that we don't know whether the URL specified
by the user is quoted or not. Rather than trying to deal with this
ourselves, we pass the problem on to Subversion. Then, we obtain the
URL from the RA instance, where it is always quoted. (It's worth
noting that the editor interface, on the other hand, always deals with
unquoted paths...)
Thus, the following invariants should apply to SubversionRepo
attributes:
- svn_url and root will always be quoted.
- subdir will always be unquoted.
Tests are added that verify that it won't affect the conversion
whether a URL is specified in quoted or unquoted form. Furthermore, a
test fixture for this is added *twice*, so that we can thoroughly test
both quoted and unquoted URLs. I'm not adding a test dedicated to
tildes in URLs; it doesn't seem necessary.

.. -*-restructuredtext-*- ============ hgsubversion ============ hgsubversion is an extension for Mercurial that allows using Mercurial as a Subversion client. At this point, hgsubversion is usable by users reasonably familiar with Mercurial as a VCS. It's not recommended to dive into hgsubversion as an introduction to Mercurial, since hgsubversion "bends the rules" a little and violates some of the typical assumptions of early Mercurial users. Installation ------------ You need to have either have Subversion 1.5 (or later) installed along with either Subvertpy 0.7.3 (or later) or the Subversion SWIG Python bindings. You need Mercurial 1.3 or later. .. _mercurial: http://selenic.com/repo/hg .. _mercurial-stable: http://selenic.com/repo/hg-stable .. _crew: http://hg.intevation.org/mercurial/crew .. _crew-stable: http://hg.intevation.org/mercurial/crew-stable If you are unfamiliar with installing Mercurial extensions, please see the UsingExtensions_ page in the Mercurial wiki. Look at the example for specifying an absolute path near the bottom of the page. You want to give the path to the top level of your clone of this repository. .. _UsingExtensions: http://mercurial.selenic.com/wiki/UsingExtensions Before using hgsubversion, I *strongly* encourage you to run the automated tests. Just use nose_ if you have it (or ``easy_install nose`` if you want it), or use ``python tests/run.py`` to run the suite with the conventional test runner. Note that because I use nose, there's a lot of stdout spew in the tests right now. The important part is that all the tests pass. .. _nose: http://code.google.com/p/python-nose/ You can check that hgsubversion is installed and properly activated using the following command:: $ hg version --svn Mercurial Distributed SCM (version ...)
