Thank you for your fast reply. I'm using macport's python27, which was
upgraded on 18. Dec 2017 to 2.7.13. That is the system-wide python
installation, as the box I'm using is dedicated solely to development of
this one piece of software, so there is no virtualenv needed, so in
particular nothing like that is being used or activated in the wsgi script
file. This is the entirety of the wsgi script:
import os, sys
# make path to the project root the first entry in sys.path, so we can
# import params.py
sys.path.insert(0, os.path.dirname(
os.path.dirname(os.path.abspath(__file__))))
# this adds everything else to sys.path defined by the current
# profile, sets up os.environ
import params
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
That hasn't changed in any way in months. The mod_wsgi.so file is located
at /usr/local/apache2/modules/mod_wsgi.so. /usr/local/apache2 is the
local apache home, where the apache I compiled is installed. I compiled
mod_wsgi from source using the following configuration:
./configure --with-apxs=/usr/local/apache2/bin/apxs
--with-python=/opt/local/bin/python
/opt/local/bin/python is a soft link
to /opt/local/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7,
the macport global python installation binary. The apache configuration to
load mod_wsgi.so is:
LoadModule wsgi_module /usr/local/apache2/modules/mod_wsgi.so
The only further configuration happens under the <VirtualHost> directive,
which is:
WSGIApplicationGroup %{GLOBAL}
# WSGIDaemonProcess trunk.delphicloud.io user=erik group=staff
processes=1 display-name=%{GROUP} header-buffer-size=65536
WSGIDaemonProcess trunk.delphicloud.io user=erik group=staff
processes=1 display-name=%{GROUP}
WSGIProcessGroup trunk.delphicloud.io
WSGIScriptAlias /
/Users/erik/web/delphicloud.io/dc-django-app/trunk/delphi_cloud/delphicloud/wsgi.py
The commented out line was my attempt to try manually increasing the
header-buffer-size parameter to see whether that would fix the problem. It
didn't.
When I run otool, I get this:
$ otool -L mod_wsgi.so
mod_wsgi.so:
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Python
(compatibility version 2.7.0, current version 2.7.0)
/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation
(compatibility version 150.0.0, current version 1259.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
1226.10.1)
/opt/local/lib/libgcc/libgcc_s.1.dylib (compatibility version 1.0.0,
current version 1.0.0)
Please let me know if I can give you any other information to help. Thanks.
