System Information issue with pygments

[Thijs Triemstra]

When I visit /about on a trac 1.1.3dev-r13408 as admin user and look at the system information table I see the following version for pygments 2.0.1:

Failed to read PKG-INFO file for Pygments 2.0.1: [Errno 2] No such file or directory: '/home/thijs/.virtualenvs/collab-trac/lib/python2.7/site-packages/Pygments-2.0.1.dist-info/PKG-INFO'

I suggest to hide the version ('unknown') or fix the issue that causes this value.

Are you using ​wheel?

[Thijs Triemstra]

This was done in a virtualenv with pip. I checked out the svn trunk and installed trac in that virtualenv with python setup.py install. Not sure if it used a wheel file, there's a Pygments-2.0.1.dist-info and pygments folder in lib/python2.7/site-packages.

Replying to thijstriemstra:

there's a Pygments-2.0.1.dist-info and pygments folder in lib/python2.7/site-packages.

Could you post the ls output for lib/python2.7/site-packages and lib/python2.7/site-packages/pygments?

If pip is 1.5.6 (probably 1.4+), it seems pip installs compiled *.whl package.

Currently, Trac doesn't support ​Wheel package, e.g. *.dist-info.

Work around is to reinstall with ​https://pypi.python.org/packages/source/P/Pygments/Pygments-2.0.1.tar.gz.

$ pip uninstall -y Pygments
$ pip install https://pypi.python.org/packages/source/P/Pygments/Pygments-2.0.1.tar.gz#md5=e0daf4c14a4fe5b630da765904de4d6c

Proposed changes in jomae.git@t11877.

[Christian Boos]

Looks good! Is this all we need to do for supporting "wheels", just a different key for the metadata?

[OT] I see you're using [#<ticket>] as a prefix for your commit messages, probably for the same reason I'm using (#ticket), i.e. commit --amend or rebase's removal of comment-like lines, however in your case this formats to a link to the #<ticket> anchor…

[Thijs Triemstra]

A backport to your LTS version would be nice as well.

[Jun Omae]

Updated jomae.git@t11877, uses *.dist-info/RECORD file to detect that a resource is in installed files.

Looks good! Is this all we need to do for supporting "wheels", just a different key for the metadata?

The wheel uses ​metadata 2.0. According to the document and actually-installed metadata file, no different key is needed.

Another issue, bdist_wheel can compile Trac-1.0.2-py2-none-any.whl included compiled message catalogs. pip 1.5 and later with *.whl package installs correctly Trac library and script files. However, pip 1.4.x install only Trac library, script files aren't installed.
