ASP.NET validation controls produce invalid XHTML markup when referencing WebResource.axd

Doing some .NET work recently and came across an issue that was pretty frustrating.  I had valid XHTML output until I added a .NET validation control to the page.  The result was that there were some script tags added to the HTML that looked like this:

<script src="/WebResource.axd?d=BSOU...Q%3d_f&t=6346...00"
type="text/javascript"></script> 

Note that the "&" is not escaped.  I decided to override the page render and use a regex to escape the URLs.  My solution is below:

Installing the latest Mono 2.10 and MonoDevelop 2.8 on ubuntu 11.10 Oneiric

I recently had reason to begin working with .NET again and decided to use Mono so I could do most of my development on Linux.  I wanted to get a parallel mono setup so I could use the latest releases of Mono and MonoDevelop without impacting my distribution's files.

Based on the recommendations of this post:

http://askubuntu.com/questions/5304/upgrading-to-latest-stable-mono

I decided to download the 2.10.8 deb from:

http://sourceforge.net/projects/mono-parallel/files/

Which worked fine and was relatively painless.

Then, I wanted to get the latest version of MonoDevelop installed as well.  I found an install script for a previous version:

https://github.com/nathanb/iws-snippets/blob/master/mono-install-scripts/ubuntu/install_monodevelop-2.6.0.1.sh

and updated it some for the following reasons:

• Referenced new versions of the source files being compiled
• download & install xulrunner & libgluezilla debs because I had build problems without using these specific versions

The resulting script which worked fine is here:

I may try this build script next time:

Targeting development versions of required packages in setup.py

Our released packages should be able to be installed just like anything else:

AuthBWC
AuthBWC==0.1.9
AuthBWC>=0.1.9
AuthBWC>0.1.9

etc.

Development versions of our packages should also be able to be installed with easy_install/pip:

    easy_install AuthBWC==dev
    pip install AuthBWC==dev

or from a requirement in setup.py like the following:

    install_requires = [
        'AuthBWC==dev',
    ],

But, the above doesn't seem to work.  I was getting errors like:

    Searching for AuthBWC==dev
    Reading http://pypi.python.org/simple/AuthBWC/
    Reading http://bitbucket.org/rsyring/authbwc/
    Best match: authbwc dev
    Downloading http://bitbucket.org/rsyring/authbwc/get/tip.zip#egg=authbwc-dev
    Processing tip.zip
    Running rsyring-authbwc-1cb0cf6b2e0d/setup.py -q bdist_egg --dist-dir /tmp/easy_install-MEGCEK/rsyring-authbwc-1cb0cf6b2e0d/egg-dist-tmp-6iqb9D
    warning: no previously-included files matching '*.pyc' found under directory 'authbwc_ta'
    Adding AuthBWC 0.1.10dev to easy-install.pth file
   
    Installed /tmp/CompWeb-build-venv/lib/python2.6/site-packages/AuthBWC-0.1.10dev-py2.6.egg
    error: Could not find required distribution AuthBWC==dev

Note that even though the package was found and installed, setuptools/distribute does not recognize version 0.1.10dev as satisfying the "==dev" requirement. 

So, I also tried:

    install_requires = [
        'AuthBWC>=dev',
    ],

Which downloaded the last released version (0.1.9), not the tip development version (0.1.10dev).  I then tried:

    install_requires = [
        'AuthBWC>0.1.9',
    ],

But that didn't work either because there wasn't anything on the pypi page pointing to a package with a version greater than 0.1.9.  That, though, was easy enough to solve, by using the following code in my setup.py file:

    ...
   
    from authbwc import VERSION
   
    NEXT_VERSION = """
    Link to tip as next version (for setup.py requirements):
    http://bitbucket.org/rsyring/authbwc/get/tip.zip#egg=AuthBWC-{0}post1
    """.format(VERSION)
   
    cdir = os.path.abspath(os.path.dirname(__file__))
    README = open(os.path.join(cdir, 'readme.rst')).read()
    CHANGELOG = open(os.path.join(cdir, 'changelog.rst')).read()
   
    setup(
        name='AuthBWC',
        version=VERSION,
        description="A user authentication and authorization component for the BlazeWeb framework",
        long_description= '\n\n'.join((README, NEXT_VERSION, CHANGELOG)),
       
        ...
    )

So, that seemed to be the end of my problems until I tried to run:

    easy_install AuthBWC

and it installed the 0.1.9post1 version from tip!

Well, I don't want easy_install installing my tip by default (Distribute's easy_install and pip did not install that version, but the original setuptool's easy_install did).  I then found this:

http://tarekziade.wordpress.com/2011/02/15/do-not-upload-dev-releases-at-pypi/

which explained some things.  Finally, I figured out that I could put the following in my setup.py file:

  install_requires = [
      'AuthBWC ==dev, >0.1.9',
  ],

easy_install seems to understand this and the result is that it downloads the package referenced on the pypi page as the 'dev' version and setuptools sees the requirement as satisfied because my tip points to source with a version of 0.1.10dev (which is > 0.1.9).

Whew! I'll be happy when distutils2 helps solve all this packaging confusion.
