Why doesn't Ocsigen run my python file?

Question

The test.conf configuration file is as follows:

<ocsigen> <server> <port>*:8000</port> <logdir>/home/zaxis/tmp/log/</logdir> <datadir>/home/zaxis/tmp/data</datadir> <user>zaxis</user> <group>wheel</group> <charset>utf-8</charset> ...... <extension findlib-package="ocsigen_ext.cgimod"> <cgitimeout value="30"/> </extension> <extension findlib-package="ocsigen_ext.staticmod"/> ...... <site path="qachina" charset="utf-8"> <cgi root="cgi-bin" dir="/media/E/www/qachina/cgi-bin"/> <static dir="/media/E/www/qachina" /> </site> .... <commandpipe>/home/zaxis/tmp/ocsigen_command</commandpipe> </server> </ocsigen> 

Then I launched Ocsigen:

ocsigeocsigen -c test.conf

I can visit http://127.0.0.1:8000/qachina/index.htm . However, Ocsigen does not execute my python script in cgi-bin, but wants the browser to load it.

BTW, all python script files can be run directly in the shell.

 >head cgi-bin/nav.py #!/usr/bin/env python # -*- coding: utf-8 -*-enter code here ... 

I cannot visit the Ocsigen mailing list, so I am posting offers here.

Answer 1

What is your version of Ocsigen?

I just tried with ocsigen 1.3.4 (the version currently being tested by Debian) and there seems to be an error (on the Ocsigen side) with your config fragment. What you want can be achieved with:

 <cgi regexp="cgi-bin/([^/]*)" dir="/usr/lib/cgi-bin/" script="\1" /> 

I just checked all running Ocsigen instances that I have access to, and they all use the "regexp" attribute. However, the documentation permits your version, and the server accepts it. One of these two alternatives is a mistake.

FYI, ocsigen works with the -V option.

Answer 2

For each request on the site, Ocsigen tries the extensions listed in the order of the configuration file. In your case, it runs staticmod, which succeeds because cgi-bin is the directory existing in the directory specified by staticmod. If you want to try cgimod first, you must put <cgi ...> before <static ...> .

Answer 3

I don’t know any solid answer, because it seems to me that it should work, but I have some questions that may be useful.

When you receive a download request, have you really downloaded it? If so, are you loading the webpage from the script, or are you loading the script yourself? If this is the first, then this is just a mime type question. If it comes later, it will most likely be a problem for the static module serving the page, and not for the CGI. Have you tried removing <static dir="/media/E/www/qachina" /> to see if this contradicts?

After changing #!/usr/bin/env python to #!/usr/local/bin/python for each python file now it works!

thanks!
