That writing input/output filters in Python using mod_python is easy I will accept. Part of my concerns though are that in making it so simple it has abstracted away too much and you have lost the ability to properly deal with the buckets in the underlying bucket brigade. The result is that although it may work in most cases, there seems to be a small subset where mod_python may not be dealing

Even though writing filters in python might not be optimal, they are hugely easier to do than implementing in C. The relevant Apache APIs are poorly documented, and there do not appear to be any useful examples you ca start from.

After trying the C implementation for a while I switched to python and had an output filter up and running quickly.

@laurence

Ahhh, but then I remembered all the other reasons why implementing Apache input/output filters in Python is bad. I'll try and blog about why mod_wsgi is unlikely to support them and why in general Python is bad for implementing them. Even so, do still come over to the mod_wsgi list if want to discuss it.

@laurence

Python isn't particularly the best language for writing Apache input/output filters as the performance hit is quite significant. So, although it wouldn't be that hard to add support for writing input/output filters in Python, I am dubious about whether it is something that should be encouraged.

@florian
I much prefer mod_wsgi in general, but mod_python still has one feature that mod_wsgi lacks: the ability to write apache filters in python.

And as for the general statements on bloat... surely you have nginx and varnish in front of anything that serves a serious amount of traffic.

@florian

One final thing about what is getting labelled here as bloat in mod_python. The extra stuff I am talking about represents at most 1MB of memory and it stays constant and doesn't increase over time. This amount isn't that much when Python web applications quite often are 30MB+ in size in their own right. In some cases the Python web applications would actually drag in the same

@florian

It matters because in some ways mod_wsgi works very similar to mod_python.

If people think that mod_python works in a certain way, when it doesn't, or that mod_python has certain problems, which may not actually be its fault directly, then they will assume that the same applies to mod_wsgi.

This isn't fiction. I have already come across people doing exactly

@Graham

so since you basically agree with the raised points, and add a few of your own like that mod_python is kinda bloated and that its development is stagnant, why does it matter who spreads what kind of missinformation about it?

The bottom line is nobody should use it.

the build in module/function dispatch algorithm

Not sure exactly what you mean here. If you mean how it supplies both a low level handler mechanism and the high level publisher dispatch mechanism then would in part agree.

I believe that mod_python should have stopped at the low level handler mechanism and made it as simple as possible. All the other high

mod_python still sucks because

- weird configuration
- need to re-configure from apache default
- fails to reload properly when configured thus (which wouldn't matter if...)
- poor hosting choices, apache only (as opposed to wsgi which you run on apache and nginx as mod_wsgi, on flup as fscgi, scgi or ajp, with

That site is the same turkey who is selling "Django 2.0". His attempts at sowing name-brand confusion (pypi.info?!) are legendary, too, unfortunately.

Good to have this information laid out clearly, but there might be an argument for not feeding the trolls in the future for that particular site.
