Trac with cherokee, unmet dependency

[jevgenij.tsoi@…]

Hej!

I was installing trac with cherokee, following instructions on TracFastCgi. I could not get tracd to start. Cherokee was giving me 503 errors.

Running tracd by hand, i got this trace:

Traceback (most recent call last):
  File "/usr/local/bin/tracd", line 9, in <module>
    load_entry_point('Trac==0.12', 'console_scripts', 'tracd')()
  File "/usr/local/lib/python2.6/dist-packages/Trac-0.12-py2.6.egg/trac/web/standalone.py", line 290, in main
    serve()
  File "/usr/local/lib/python2.6/dist-packages/Trac-0.12-py2.6.egg/trac/web/standalone.py", line 272, in serve
    None, None, ['']).WSGIServer
ImportError: No module named flup.server.scgi

Anyway, installing python-flup fixed the problem. But it was in no way obvious.

I don't know, maybe you could add some directions in the scgi section, on this dependency.

Setup: Ubuntu 10.10 server python 2.6 trac 0.12 installed via easy_install cherokee 1.0.12 installed via ubuntu ppa

Thank you for a great app! /JT

Yes, the support for scgi and ajp via flup in tracd has somewhat sneaked in without being documented (r3081). Feel free to help improve the documentation, the TracFastCgi page is editable by all.

[jevgenij.tsoi@…]

TracFastCgi has been modified to reflect this dependency.

I do not know if this is needed for other protocol types. If so, it might be a good idea to make python-flup an explicit dependency.

Because the installation feature has been documented in TracFastCgi and given the specificity of the issue, marking this as an enhancement.

We could wrap the import statement in a try / except and report that python-flup needs to be installed when an ImportError is raised. Other than that, I don't see any actions that needs to be taken for this ticket.

Fixed on 1.0-stable in r16276, merged in r16277, r16278.

main in trac.web.standalone doesn't call translation.activate(get_console_locale()). The main shouldn't call it. Therefore, the following message never be localized.

            except ImportError:
                printerr(_("Install the flup package to use the '%(protocol)s' "
                           "protocol", protocol=options.protocol))
                sys.exit(1)

Thanks for noticing. I'll remove the translation marker.

Fixed on 1.0-stable in r16279, merged to 1.2-stable in r16280, merged to trunk in r16281.
