Python version and Apache mod_python mismatching version
Hello, I have a Centos7 web server with python 2.7 installed and I want Apache to serve python scripts so I figure I have to install mod_python: i know that this module is deprecated, but I need it only for internal pourposes. Is the mod_python version (which is 3.5 with Python 3 support) somehow related to the python interpreter the web server? Is there any problem if the mod_python version and python version didn't match? -- https://mail.python.org/mailman/listinfo/python-list
Apache/mod_python: Registering a request handler dynamically
Hi,
Is there a way to dynamically overwrite the request handler from within
mod_python scripts? Something along those lines:
---
from mod_python import apache
def myhandler(request):
request.content_type = 'text/plain'
request.write('Hello world')
apache.set_default_handler(myhandler)
---
I specifically want to avoid changing the Apache directive, as this code
is supposed to function in a place where the user has no permission to
override the Apache directive.
The reason is that I am trying to hide the difference between different
environments (such as mod_python or CGI) from the developer, such that
the following is possible:
---
#!/usr/bin/python
import os, os.path
os.chdir(os.path.dirname(__file__))
from PleaseHideMyEnvironment import RequestHandler
def index(request):
request.write('Hello World')
RequestHandler(index)
---
So at the time at which RequestHandler() is created, I need a way to make
sure that mod_python calls to the RequestHandler instead of the normal
handler, whenever a new request is made.
Any idea?

Hi,
I should get a non-empty "form".
With the following html
...and the following "upload.py":
from mod_python import util, apache
def index(req):
form = util.FieldStorage(req, keep_blank_values=1)
try:
some_text = form.get('some_text', None);
return form.items
except Exception, e:
return 'Fail: ' + str(e)
...I get (writting "Python" in the text box)
[('some_text', Field('some_text', 'Python'))]
So, I have a "form" with a non-empty structure of (key, value), and
I'm able to get the value I'm looking for:
...
some_text = form.get('some_text', None) # It's not empty anymore
...
Thanks

Which is the correct result for the code you are using.
The problem is that you appear to be using mod_python.publisher which
does its own form handling before you are even getting a chance, thus
it is consuming the request content.

Apache & mod_python: I don't receive anything with POST method
Hi,
I'm using a simple form to make possible the users of our site upload
files.
The "upload.py" looks like this:
from mod_python import apache, util;
def index(req):
form = util.FieldStorage(req, keep_blank_values=1)
try:
# form is empty here
# return form --> I get "{}"
ufile = form.get('upfile', None)
if not form.has_key('upfile'):
return ":( No 'upfile' key"
# some checks. I never get beyond here
ufile = form['upfile']
if ufile.file:
return ufile.file.name
else:
return ":( It's not a file"
except Exception, e:
return 'Fail: ' + str(e)
I'm getting an empty 'form'. No 'upfile' key at all. I've tried to add
some other text fields but the result is the same: empty. If I use GET
method with text fields, it works properly.
Currently I'm using:
Apache 2.2.9 (initially I used Apache 2.2.3 too)
mod_python 3.3.1 (initially I used mod_python 3.2.10 too)
Python 2.5.2
Thanks

the problem isn't that you can get a number, it's that the number you
get has no *direct* correlation to the amount of memory your process can
actually allocate -- or at least allocate without causing excessive
swapping or triggering the OOM killer or otherwise annoying all the
other processes on the machine.

unless you do utterly trivial things, a process allocates memory from a
lot of different resource pools (i/o buffers, virtual memory buffers,
network buffers, graphics resources, etc). there's simply no way for
the process itself to know how much memory it uses. if you want to
know, ask the operating system.

as I said, use standard process monitoring tools (i.e. "ps" and "top"
etc on Unix, the task manager on Windows) takes you a long way.

it doesn't have to be harder than this:
# problematic area of code
raw_input("before: check memory here")
for i in xrange(100):
x = foo()
raw_input("after: check memory here")
on unix, you can also do e.g. os.system("ps ux") or os.system("ps -F -p
%d" % os.getpid()) or some variation thereof.

running individual modules/classes/functions under test harnesses, so
you can analyze their behaviour under well-known conditions.

Not me. I didn't (still don't actually) recognise Ilias' name. I was actually thinking: (d) Python is so great that there can never be any memory leaks! but I guess that's probably wishful thinking. So... how do you measure memory usage in Python? Every programming language I've used before (not a huge range, I'll admit) had *some* sort of facility to measure memory usage, typically things like: * how much memory is free in the stack? * how much memory is free in the heap? * how big a block does this pointer point to? * how much memory does this record/struct/object/string use? Unless I've missed something, I don't believe Python does *any* of that. It could be quite useful. The timeit module is good for measuring the time taken for code to run, but as near as I can tell, there's no way to optimize memory use except prematurely. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list

Detecting memory leaks on apache, mod_python
How to detect memory leaks of python programms, which run in an environment like this: * Suse Linux 9.3 * Apache * mod_python The problem occoured after some updates on the infrastructure. It's most possibly caused by trac and it's dependencies, but several components of the OS where updated, too. Any nice tools which play with the above constellation?

Doing that would probably be considered bad practice. I think the
problem was I neglected to mention you would have to change your
RewriteRule to add a slash when used in Directory directive. Ie., use:
RewriteEngine On
# If its not here...
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Look here instead...
RewriteRule (.*) /py/$1 [PT]
Note the slash after /py.
This works for me when I test it.

Thank you.
the RewriteCond just needs the absolute path:
RewriteEngine On
# If its not here...
RewriteCond /var/www/btsgroup.de/htdocs/%{REQUEST_FILENAME} !-f
RewriteCond /var/www/btsgroup.de/htdocs/%{REQUEST_FILENAME} !-d
# Look here instead...
RewriteRule (.*) /py$1 [PT]

I did say you would probably need to restrict the scope of the
mod_rewrite rule to a specific context. In particular, put it inside
of a Directory directive corresponding to the file system directory
where your files live. Where you have it as the moment,
REQUEST_FILENAME probably will not resolve to anything as Apache
hasn't yet matched it to the filesystem. Thus:
RewriteEngine On
# If its not here...
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Look here instead...
RewriteRule (.*) /py$1 [PT]

The rewrite rule works, but now every request ist send to /py.
This is my .conf:
DocumentRoot /var/www/mydomain.com/htdocs
ServerName mydomain.com
ServerAlias www.mydomain.com
SetHandler python-program
PythonHandler django.core.handlers.modpython
PythonPath "['/var/www/mydomain.com/htdocs/py'] + sys.path"
SetEnv DJANGO_SETTINGS_MODULE myapp.settings
PythonDebug Off
RewriteEngine On
# If its not here...
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Look here instead...
RewriteRule (.*) /py$1 [PT]
ErrorLog /var/www/mydomain.com/logs/error.log
CustomLog /var/www/mydomain.com/logs/access.log common

For the more general case of where a HTTP 404 error would otherwise be
returned, indicating that a resource could not be found, as opposed to
an actual physical file, you can just use:
ErrorDocument 404 /py
This would be simpler than using mod_rewrite. I can't remember though
whether the handler when triggered in this case can change the
response status to something other than 404.
You could use mod_rewrite if you really must, but not sure how it
would interact with virtual resources managed by some handler where no
actual file exists. To be practical you would probably want to
restrict the scope of mod_rewrite to specific contexts.
Quoting an example from very good book "The Definitive Guide to Apache
mod_rewrite", you can do something similar to:
RewriteEngine On
# If its not here ...
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Look here instead ...
RewriteRule ^/images/(.*) /pics/$1 [PT]
In this case it is causing lookups for images to be made in two
places, but your case wouldn't be much different.

There are no issues with the thread safety of the Python interpreter per-se. However, as with any Python application, whether mod_python is used or not, if multiple threads are being used your application code may have to be written so as to cope with access to code/data from multiple threads at the same time. This is not anything unique to mod_python. Whether this will be an issue or not is dependent on which Apache MPM is used, not that the Apache MPM is used as one will always be used. The specific Apache MPMs where multithreading has to be taken into consideration are "winnt" on Windows platforms and "worker" on UNIX platforms. What this all means is that when these MPMs are used there can be concurrent request handlers executing in distinct threads within the same Apache processes. Thus, where common data is accessed, it has to be adequately protected. For further details on the Apache/mod_python process/interpreter/thread model, see: http://www.dscpl.com.au/wiki/ModPython/Articles/TheProcessInterpreterModel That said, there are sometimes threading issues with mod_python but it is more to do with the fact that mod_python can use multiple interpreter instances within a single process. Also, the problems are not a problem in mod_python, but result from third party C modules for Python being used which take the simple path of using the simplified thread API for working with the GIL. Such modules often will not work properly when used from secondary Python interpreter instances. In these cases it is a simple matter of telling mod_python to handle requests which are dependent on those modules within the main Python interpreter, ie., the very first one which gets created. Where third party C modules use the full thread API for Python properly, it doesn't matter which interpreter instance they are used from. Graham -- http://mail.python.org/mailman/listinfo/python-list

If you can get that working, then try something harder. You are also better off asking mod_python questions on the mod_python mailing list.

apache mod_python problem
Hi all, I have succesfully installed apache+mod_python (ubuntu 5.10 (Breezy), libapache2-mod-python2.4 Version: 3.1.3-3ubuntu1, apache2 Version: 2.0.54-5ubuntu4, python2.4 Version: 2.4.2-1). It seems apache and everything functions fine. I tried to run the example application from the mod_python site (http://www.modpython.org/examples/psp_site.tgz) by decompressing the tgz file in a place where apache can find it, and then access it via mozilla firefox (simply http://127.0.0.1/psp_site/ where 'psp-site' is the name of the directory.) However, instead of running the index.py page like it shoud, I just get the list of files, as in: Index of /psp_site Icon NameLast modified Size Description[DIR] Parent Directory - [TXT] PyFontify.py15-Feb-2006 23:02 4.3K [DIR] images/ 15-Feb-2006 23:02- [TXT] index.py15-Feb-2006 23:02 3.4K [ ] index.pyc 15-Feb-2006 23:02 4.1K [TXT] py2html.py 15-Feb-2006 23:02 13K [DIR] styles/ 15-Feb-2006 23:02- [DIR] templates/ 15-Feb-2006 23:02- [TXT] view.py 15-Feb-2006 23:02 726 and clicking any of the .py files just opens the 'open/save' menu. The .htaccess file contains: SetHandler mod_python PythonHandler mod_python.publisher PythonDebug On everything is exactly as it is on "http://www.modpython.org/examples/";, I didn't change anything. Anyone has any idea as to what went wrong? Thank you in advance, Ido Yehieli. -- http://mail.python.org/mailman/listinfo/python-list

problem running a python script using apache,mod_python on linux
hi,
i m trying to integrate python with apache on linux.For this i m using
mod_python.
I dont see any problem with the versions of python,apache and
mod_python i m using.
the versions i m using are
apache version2.
mod_python v3.1.14
python2.4
The problem is,when i m running my python script,after starting apache
,it is showing me the code it has.
My error_log is showing the following message
[Tue Oct 18 19:01:06 2005] [notice] Apache/2.0.55 (Unix)
mod_python/3.1.4 Python/2.4.2 configured -- resuming normal operations
[Tue Oct 18 19:01:06 2005] [info] Server built: Oct 17 2005 13:07:52
[Tue Oct 18 19:01:06 2005] [debug] prefork.c(956): AcceptMutex: sysvsem
(default: sysvsem)
the access_log is showing this message:
127.0.0.1 - - [18/Oct/2005:19:01:14 +0530] "GET /apache_pb.gif
HTTP/1.1" 200 2326
127.0.0.1 - - [18/Oct/2005:19:01:19 +0530] "GET /test/mptest.py
HTTP/1.1" 200 110
from the python script,i m returning an apache.OK ,so i think it goin
on fine,as i m getting 200i.e the hhtp processing is goin on fine.
I have made the required changes to the httpd.conf file
***
LoadModule python_module /home/ngupta/Apache2/modules/mod_python.so
DocumentRoot "/home/ngupta/Apache2/htdocs"
AllowOverride FileInfo
***
I m using a .htaccess file placed under Apache2/htdocs/test/
The .htaccess file has the following code
**
AddHandler mod_python .py
PythonHandler mptest
PythonDebug On
**
where mptest is python script and is as follows
**
from mod_python import apache
def handler(req):
req.send_http_header()
req.write("Hello")
return apache.OK
**
so if anyone knows where the problem lies ,please tell me.
thanks.

The documentation is a bit lacking, and I've I use mod_python for all my web stuff, including several live production sites - no problems so far. Admittedly, I don't use anything too complicated - usually just the handler and publisher syntax and a little bit of authentication. Plus MySQL on the back end. >From what I've been told, the one gotcha is that you want to make sure that different on-server users aren't sharing the same copy of mod_python, since they'll have a shared context. Which would only a problem where you're running a server open for lots of people to set up their own pages.

Apache/mod_python & MySQLdb
AIUI, global variables are supposed to be preserved within each Apache thread/prcoess. However, I'm importing and using MySQLdb within a class in a separate module, which is in turn imported and used within a _function (ie. not "published"). So, AFAICT, it's not supposed to be preseved. But unless I specifically close() the database connection, it gets stranded and I eventually run out of connections, even if I del the connection and cursor objects. What gives? What happened to GC? Also, is there an easy way to run pychecker on mod_python scripts? It fails since _apache doesn't exist outside of Apache regards, Confused & tired of PHP. -- http://mail.python.org/mailman/listinfo/python-list
