dir2pi normalization broken for some wheel packages

[dhagrow]

I'm looking specifically at the wheel for python-dateutil. I did the following:

$ pip2tgz pkgs/ python-dateutil

I then tried dir2pi with all the different normalization options (-n, -N, -a). pip installing from this index does not work in any case:

$ pip install --index-url file:///<blah>/pkgs/simple/ python-dateutil -v
...
Looking in indexes: file:///<blah>/pkgs/simple/
Collecting python-dateutil
  1 location(s) to search for versions of python-dateutil:
  * file:///<blah>/pkgs/simple/python-dateutil/
  Getting page file:///<blah>/pkgs/simple/python-dateutil/
   file: URL is directory, getting file:///<blah>/pkgs/simple/python-dateutil/index.html
  Analyzing links from page file:///<blah>/pkgs/simple/python-dateutil/index.html
    Skipping link file:///<blah>/pkgs/simple/python-dateutil/python-dateutil-2.7.2-py2.py3-none-any.whl (from file:///<blah>/pkgs/simple/python-dateutil/index.html); wrong project name (not python-dateutil)

However, if I manually rename the package name in simple/python-dateutil to use an underscore: python_dateutil-2.7.2-py2.py3-none-any.whl, and edit index.html to point to it, everything works:

$ pip install --index-url file:///<blah>/pkgs/simple/ python-dateutil -v
...
  Analyzing links from page file:///<blah>/pkgs/simple/python-dateutil/index.html
    Found link file:///<blah>/pkgs/simple/python-dateutil/python_dateutil-2.7.2-py2.py3-none-any.whl (from file:///<blah>/pkgs/simple/python-dateutil/index.html), version: 2.7.2

The problem seems to be with the way Wheel parses the filenames.

I can confirm everything above. In my case I created a package with package name yaml_cfg.

Here is what is generated in /path/packages/wheels/simple/yaml-cfg/ (using dir2pi):

.
├── index.html
└── yaml-cfg-0.1.2-py2.py3-none-any.whl -> ../../yaml_cfg-0.1.2-py2.py3-none-any.whl

Note yaml-cfg-0.1.2-py2.py3-none-any.whl is a symlink pointing to /path/packages/wheels/yaml_cfg-0.1.2-py2.py3-none-any.whl.

Here is the content of index.html:

<a href='yaml-cfg-0.1.2-py2.py3-none-any.whl'>yaml-cfg-0.1.2-py2.py3-none-any.whl</a><br />

and here is the error upon invoking pip install yaml-cfg or pip install yaml_cfg:

Getting page file:///path/packages/wheels/simple/yaml-cfg/
   file: URL is directory, getting file:///path/packages/wheels/simple/yaml-cfg/index.html
  Analyzing links from page file:///path/packages/wheels/simple/yaml-cfg/index.html
    Skipping link file:///path/packages/wheels/simple/yaml-cfg/yaml-cfg-0.1.2-py2.py3-none-any.whl (from file:///path/packages/wheels/simple/yaml-cfg/index.html); wrong project name (not yaml-cfg)

If I modify index.html as such:

<a href='yaml_cfg-0.1.2-py2.py3-none-any.whl'>yaml-cfg-0.1.2-py2.py3-none-any.whl</a><br />

and do mv /path/packages/wheels/simple/yaml-cfg/yaml-cfg-0.1.2-py2.py3-none-any.whl /path/packages/wheels/simple/yaml-cfg/yaml_cfg-0.1.2-py2.py3-none-any.whl, then I can install using pip.

It seems crucial for pip that the name used in the link located in index.html be the same as the package name.

I hadn't noticed before, but it appears there's been a pull request (#67) for some time now that fixes this issue.
