Handle wildcard in Directory to sys.path transfer
-------------------------------------------------
Key: MODPYTHON-63
URL: http://issues.apache.org/jira/browse/MODPYTHON-63
Project: mod_python
Type: Improvement
Versions: 3.1.3
Environment: gentoo Linux 2.4.20-gentoo-r8 apache-2.0.54-r8 mod_python-3.1.3-r1
Reporter: Kevin Quick
Priority: Minor
Below is a patch that does two things:
1) On module import failures, logfile contains additional information showing
system paths as well as module name.
2) Support of Python*Handler found in a wildcard-based directory. For example,
<IfModule mod_python.c>
<Directory /home/*/public_html/python>
AddHandler mod_python .py
PythonHandler helloworld
PythonDebug on
</Directory>
</IfModule>
which mirrors a corresponding perl setting and would allow the user to
place a mod_python handler in their $HOME/public_html/python directory.
In the current code, the wildcard is not translated, the sys.path update
will be invalid, and the user's module will not be accessible. The attached
patch provides a fix for this.
N.B. There are obvious security issues in using this type of configuration,
but this is very useful for dev environments, and security would implemented
via explicit alternatives anyhow.
