Tagged and released mod_wsgi 1.2 and 2.0c1.

[Graham Dumpleton]

I have tagged and release mod_wsgi 1.2, plus a first release candidate
for 2.0. Files are available from:

http://code.google.com/p/modwsgi/downloads/list

Details for mod_wsgi 1.2 are in:

http://code.google.com/p/modwsgi/wiki/ChangesInVersion0102

It is highly recommended that all users of Apache 1.3 and Apache 2.0
upgrade to this version as it includes a fix for an issue whereby if
default for WSGIApplicationGroup is used, or %{RESOURCE} is used, that
particular URLs could result in a second Python sub interpreter
instance being created for each resource/application. This would have
the affect of doubling the amount of memory in use for that
application which in a constrained memory environment could cause
physical memory to be used up and swapping to occur, or cause you to
unexpectedly reach any VPS memory limit. This issue does not affect
users of Apache 2.2.

Details for mod_wsgi 2.0c1 are in:

http://code.google.com/p/modwsgi/wiki/ChangesInVersion0200

This should only be used by those who like to test out the latest
version and give feedback.

Primary thing of interest in this version is 'Process' option for
WSGIReloadMechanism to make it easier to restart an application
running in a mod_wsgi daemon process when code changes are made. When
enabled, only need to touch the WSGI script file when you want
application to be reloaded.

Other significant changes include ability to hook into Apache 2.2 auth
provider mechanism, support for Python virtual environments and the
beginning of some hooks to be able to work with the internal Apache
APIs. Check out the changes file for further details.

Bernd and Adal, feel free to make Debian and Windows binaries. The
2.0c1 version should probably target just the unstable tree of Debian
release tree.

Thanks.

I've made available a Mercurial repository of my Portage overlay,
which currently only contains a mod_wsgi-1.2 ebuild. You can clone it
or download a tarball from the web, at
http://hg.xavamedia.nl/portage/.

PKGBUILD for Archlinux for stable version is updated too :
<http://aur.archlinux.org/packages.php?do_Details=1&ID=13394>

I need to tweak a little bit how the package is named so that mod_wsgi
1.x & 2.x are not in conflit within AUR.

Should be fixed soon :-)

[Adal Chiriliuc]

I have updated the Windows binaries. The 2.0c1 version builds only
after moving the "DispatchObject *adapter = NULL;" declaration from
around line 5495 to the start of the block.

Couldn't test them though.

I'm getting this error, can't figure out why since the path seems to
be ok (and I can run "from paste.deploy import loadapp" in the CLI
python). I'm not testing on my usual computer, so it could be a
configuration problem.

[Graham Dumpleton]

Are you setting WSGIPythonPath directive?

This behaves a bit differently now and calls site.addsitedir() instead
of just setting PYTHONPATH environment variable. It may be screwing
things up.

Graham

[Graham Dumpleton]

BTW, if you are using WSGIPythonPath, create a hello world program
which echos back sys.path. In looking at value for WSGIPythonPath I
split it into separate directories and for Windows it should split on
';' and not ':', but if I am stuffing up somehow then any drive
specifier could be causing an issue. Also, not sure whether I may have
changed the behaviour in respect of how backslashes are treated. I
could well have changed it inadvertently without realising.

So, look carefully at sys.path and adjust backslash escaping, or use
forward slashes.

I'm not using WSGIPythonPath.

Here's my configuration:

LoadModule wsgi_module "../mod_wsgi/win32/
mod_wsgi_py25_apache22_Release/mod_wsgi.so"

WSGIOutputBuffering On
WSGIScriptReloading Off

WSGIScriptAlias / X:/Project/Anim/Website/AnimWeb/anim.wsgi

I think I had this problem before, but I don't remember the details.

Graham,

mod_wsgi 1.2 was uploaded to Debian's unstable.

While preparing 2.0c1 for experimental we hit the following problem:

The 1.X packages were all built using the apache-threaded-dev package,
which provides the necessary environment to build modules for all
threaded workers (like apache-mpm-worker). So far the package suggested
to use threaded workers and did not explicitly conflict with the
apache-mkm-prefork, as mod_wsgi worked well in the preforking
environment, even when it was built against the threaded-dev package.

With 2.0c1 I run into the problem that mod_wsgi doesn't work anymore if
it was built using the threaded-dev, if you run it with the preforking
worker.
/usr/lib/apache2/modules/mod_wsgi.so: undefined symbol: ap_thread_stacksize
Although this sounds obvious, the real problem for me is that I can't
install apache2-prefork-dev and apache2-threaded-dev at the same time,
which means I can't use them both as build-dependencies.

So the options I have now are:

- Build against -threaded-dev, conflict with the prefork worker. This
will probably make the php lovers upset, as their broken ******* doesn't
work with the threaded worker.

- Build against -prefork-dev. I didn't try if the module would work in
the preforking environment, but that wouldn't make me happy anyway.

- Put the source of mod-wsgi into Debian twice (not an acceptable
option, but I wanted to mention it).

- Build two packages and copy the apache-threaded-dev files into a
temporary directory and patch them so they look like apache-prefork-dev
and build against them. Pretty ugly way, and it needs to follow chances
in the -dev packages.

- Ask the apache maintainer to modify the -dev packages so they're
installable at the same time, probably using dpkg-alternatives, but this
is not really an easy task, so I'm looking for alternatives first.

Best regards,

Bernd

Patch mod_wsgi.c and delete:

#if defined(AP_MPM_WANT_SET_STACKSIZE)
else {
if (ap_thread_stacksize != 0) {
apr_threadattr_stacksize_set(thread_attr, ap_thread_stacksize);
}
}
#endif

It is not critical. I was just trying to inherit stack size from
ThreadStackSize directive. Just means that someone will need to set
both ThreadStackSize and stack-size option to WSGIDaemonProcess. Since
rare that this would required, not too concerned in dropping it if it
causes problems.

It doesn't work for me anymore, and i don't see any error's in my log
file ?
Has it to do with the built notification ?

[Graham Dumpleton]

Define doesn't work. What do you see from browser, a 500 page?

Can you add to your WSGI script file at start before anything else:

import sys
print >> sys.stderr, 'module #1'

Does this appear in error logs? Sprinkle such debug at end of script
file and also in the application function so can work out where
execution gets to.

> Has it to do with the built notification ?

No.

You are using WSGIPythonPath. Can you comment that out and set
sys.path in the WSGI script instead and see if it works. There may be
an issue with WSGIPythonPath on Windows in this version.
