init/update catalog now need an installed trac

[nzoltan]

Trac is not installed on my build environment. r9786 is not built anymore.

[build]$ python setup.py update_catalog -l hu

Traceback (most recent call last):
  File "setup.py", line 33, in ?
    from trac.util.dist import get_l10n_js_cmdclass

  File "/usr/lib/python2.4/site-packages/pkg_resources.py", line 483, in resolve
    raise DistributionNotFound(req)  # XXX put more info here
pkg_resources.DistributionNotFound: Trac

Is it a bug or feature?

A bug …

Try replacing with:

try:
    __version__ = __import__('pkg_resources').get_distribution('Trac').version
except pkg_resources.DistributionNotFound:
    __version__ = '0.12dev'

[Christian Boos]

Ah wait, I suppose all you need to do is to issue a python setup.py egg_info command before init/update.

Ah yes, chicken … egg_info problem ;-)

So comment:1 seems the way to go.

Still no luck. :(

[build]$ python setup.py update_catalog -l hu

[Christian Boos]

Ok, no idea why there was a __import__('pkg_resources') - maybe there was a good reason…

If not, the following should do:

from pkg_resources import DistributionNotFound, get_distribution

try:
    __version__ = get_distribution('Trac').version
except DistributionNotFound:
    __version__ = '0.12dev'

The "python setup.py update_catalog -l hu" is now works fine, but:

[build]$ python setup.py init_catalog_js -l hu

usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: invalid command 'init_catalog_js'

and the "update_catalog_js" result is same. How can I create the messages-js.po file?

[Christian Boos]

Sorry, my instructions were not clear, comment:6 was a patch for source:/trunk/trac/__init__.py​, I'll write a real patch later today.

No, it's my fault, the traceback root is the __init__.py, I was careless, sorry. :) Now everything works fine with the modified __init__.py.

[Christian Boos]

Fix applied in [9806].

I suppose the __import__('pkg_resources') was preferred to import pkg_resources in order to keep the trac namespace clean, so we could add a del get_distribution, DistributionNotFound to reach the same effect, though I don't think it's worth the trouble.

I have the same problem with 0.12 AND 0.13
