r1114 Call to fopen() failed for '/srv/www/mysql.py'. WSGIImportScript

[gert]

I did it again :-) /srv/www/mysql.py does indeed not exist but the
error message takes down the whole wsgipythonpath again

WSGIImportScript /srv/www/mysql.py process-group=%{GLOBAL} application-
group=%{GLOBAL}

No access to source checkout at moment, but in wsgi_python_child_init(), find:

if (!module) {
module = wsgi_load_source(p, NULL, name, exists,
entry->handler_script,
entry->process_group,
entry->application_group);
}

Try changing that to:

if (!module) {
module = wsgi_load_source(p, NULL, name, exists,
entry->handler_script,
entry->process_group,
entry->application_group);

if (PyErr_Occurred())
PyErr_Clear();
}

Fix indenting as necessary.

If works, will fix code later.

Hmmm, I wander if the issue:

http://code.google.com/p/modwsgi/issues/detail?id=78

is also somehow related to mod_wsgi not clearing Python exception
state when it wants to ignore the error, this subsequently causing a
problem. For that issue wasn't getting a full error log output, so
don't know full context.

yep works also tested WSGIScriptAlias pointing to something that does
not exist

WSGIImportScript /srv/www/bogus.py process-group=%{GLOBAL} application-
group=%{GLOBAL}
WSGIScriptAlias /wsgi /srv/www/bogus.py

ps what does this mean ?

mod_wsgi.c: In function 'wsgi_log_script_error':
mod_wsgi.c:6727: warning: format not a string literal and no format
arguments

[Graham Dumpleton]

2008/11/12 gert <gert.c...@gmail.com>:

It means it should be:

ap_log_rerror(APLOG_MARK, WSGI_LOG_ERR(0), r, "%s", message);

I already fixed this in trunk a week or so ago.
