install - python2.6 to 2.7 - virtualenv - index out of range - tag_svn - tickect 10658

[James Cook]

Hallo Folks,

I've had python/trac running on a hosted/managed server where I'm not
root etc. for quite a time.

Now the underlying system has been switched from python2.6 to 2.7.
Subversion has gone from 1.6 to 1.7

So I've updated the virtualenv - and now have:
# ~/virtualpython/lib/python2.7/site-packages/

In the old setup
#~/virtualpython/lib/python2.6/site-packages/
I had Trac-0.13dev_r11008-py2.6.egg

In ~/virtualpython/bin I do:
# easy_install -U Trac==dev
which begins to install - but flags up an Index out of Range Error at
the end ... which is a known problem
See http://trac.edgewall.org/ticket/10658

It seems the subversion/svn update to 1.7 leads to this error.
__________________________________________________________

I can see that I have to patch the setup.py file in the dev
distribution (of Trac) before installation. But I'm unclear how to
proceed.

My questions are:

* would directly copying the Trac-0.13dev_r11008-py2.6.egg to
~/virtualpython/lib/python2.7/site-packages/ just WORK?

If not:
* How/Where do I find the sources for dev?
** I can find 0.12, 0.11 as tar.gzs etc. but not dev
** Doing a trunk checkout :
svn co http://svn.edgewall.org/repos/trac/trunk trac
as advised on page
http://trac.edgewall.org/wiki/TracDownload#Tractrunk
seems to return 0.12!?

* Is it posible to (MUST I?) check out the exact revision 11008 to
match my previous running python2.6 installation?
* what is the easy-install command to install the patched source
directory?

Thanks for any pointers
JC

I've never been successful in doing this. Best I can tell, you must create the egg against the version of Python you are using.

What makes you think that checking out the trunk returns 0.12? The trunk is 1.0dev, the latest revision as of today being r11115. You should see 1.0dev-r11115 in the Trac footer.

svn co http://svn.edgewall.org/repos/trac/trunk trac

source ~/virtualpython/lib/python2.7/bin/activate
python setup.py install

Thanks for your reply.

I re-checked the svn co and you were right. I must have viewed the wrong directory

 

I applied the patch, but still got the same error.

So I deleted the tag_svn line as shown in http://trac.edgewall.org/ticket/10479.

At least that stopped the errors

The new egg is in the correct location. (BTW it's twice the size of the old 2.6/Trac egg - is that right?)

 

But when I access trac on the website I get:

# malformed header from script. Bad header= XXXXXX/virtualpython/l: index.cgi  

 

When I run ./trac.cgi (I know) directly in cgi-bin

It reports :

Trac detected an internal error: 'SERVER_PORT'

Traceback (most recent call last):

File "./trac.cgi", line 36, in <module>

cgi_frontend.run()

File "build/bdist.freebsd-8.3-RELEASE-p1-amd64/egg/trac/web/cgi_frontend.py", line 71, in run

return int(self.environ['SERVER_PORT'])

KeyError: 'SERVER_PORT'

 

Which I've seen in error messages.

I've checked the web/trac directory structure and it is 755 all the way down.
I've tried setting the SERVER_PORT to 80 in trac.cgi but then I just getting a SERVER_NAME error ...

I've tried setting the SERVER_NAME to xxxx in trac.cgi but then I just getting a REQUEST_METHOD error ...

so that doesn't seem like a good path to follow.

 

I even tried

# trac-admin ~/trac-sites/<instance name> upgrade

 

As I said, this trac instance has been up and running since Feb2012. It's on a managed server, hence all the virtualpython stuff.

I reckon I'm just missing a small detail somewhere here.

Errmm, not sure now, must have been checking the wrong directory(!)

svn co http://svn.edgewall.org/repos/trac/trunk trac

source ~/virtualpython/lib/python2.7/bin/activate

 

 

source ~/virtualpython/bin/activate the same thing?

 

 

python setup.py install
