Currently, version of pypi:Pygments is 2.0rc1. If it is installed, cannot load trac.mimeview.pygments.

Strange…

Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
Module readline not available.

>>> import trac.mimeview.pygments
>>> import pygments
>>> pygments.__version__
'2.0rc1'

(installed via easy_install pygments)

I then used pip to uninstall/install it again, same result, no error for me.

The issue is reproduced with 0.12-stable and 1.0-stable. No error with trunk.

I can reproduce the issue shown in comment:4 for Trac 0.12.6 and Trac 1.0.2 with Python 2.7.6 and Pygments 2.0rc1 on Ubuntu 14.04. No error with Trac 1.1.2.

Replying to jomae:

My bad, I checked trunk only.

Proposed changes in [4580ae4f/jomae.git] (jomae.git@t11796_1.0) and [930ea97a/jomae.git] (jomae.git@t11796_0.12). Confirmed with Pygments 0.6 through 2.0rc1.

What's your take on the question of having a last 0.12.7 bugfix release vs. keeping 0.12-stable as it is and save 0.12.7 for a security fix release, should the latter be needed?

Milestone: 0.12.71.0.3

Retargeting 1.0.3 for this is okay to me. The issue is minor and it's easy to prevent it by a user.

However, I think we should have a last 0.12.7 bugfix release. We didn't import latest translations for 0.12-stable contributed by translators on Transifex in releasing 0.12.6. This is that we ignore contributors' work and time, I think.

IMO, I have interest on 0.12-stable because our company still uses 0.12-stable for Trac hosting. Of course, we have a plan which these migrate to 1.0-stable….

Any chance we have 1.0.3 released sooner than January 2015?

It's usually just fine to install from source (even more so shortly after releases).

comment:11 by anonymous, 10 years ago

It's not so off topic, since this issue is a sort of breaking one.

Thanks for the reply, though.

See #11827 for information on the next release.

Just ran into this issue myself with Trac 0.12.7 —- wouldn't it be reasonable to backport this change to 0.12.8?
