Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Graham Dumpleton]

You maybe should read:

https://modwsgi.readthedocs.io/en/develop/user-guides/reloading-source-code.html
 


Source code is not automatically reloaded.

You can also have issues if you have .pyc file which have incorrect 
modification time such that they appear newer. This can arise if you copy 
source code and .pyc files from another system and don't preserve time stamps.

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Jeremy Hawkins]

not 100% sure why, but the issue is resolved.

I think there is an issue with the mod_wsgi not updating when changes are 
made to the application.
There was a change to the form to make a field optional instead of required 
and that change didn't seem to push through.
I finally was able to get errors from the form validation.  restarting the 
Apache process then testing again and it seems to be working.

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Jeremy Hawkins]

I hope this is what you're asking for.

The form is in a dialog inside of a page that is located at 
online/admin/faculty/
the form action is set to {{url_for('admin.update_faculty', 
id=faculty.facultyno)}} which converts to /online/admin/faculty/ and 
the method is post.

The headers for the request is:


   1. Request URL: 
   https://sy-devsophia.hccs.edu/online/admin/faculty/901162977
   2. Request Method: 
   POST
   
The location is the response header is:
Location: 
https://sy-devsophia.hccs.edu/online/admin/faculty/901162977


The url rules for both of these locations are:


blueprint.add_url_rule(
'/faculty/', endpoint='get_faculty', view_func=get_faculty)

blueprint.add_url_rule('/faculty/', endpoint='update_faculty',
view_func=update_faculty, methods=['POST'])

The update_faculty does end with a return 
redirect(url_for('admin.get_faculty',id=id))
I am wondering if this is the reason the response code is 302 instead of 
200.
I do have logger statements at the start of the update_faculty method which 
runs, but additional logger statements in the method do not run.

And what was the original URL the POST request was made against?

How is the Flask handler defined which is meant to handle the URL for the POST 
request?

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Jay Rat]

The alias in the Apache config I'll have to look at monday. Think its
/online but cant recall of there is at the end or not

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Graham Dumpleton]

You didn't answer my other questions.

What does the Location header in responses say?

How do you have WSGIScriptAlias set in the Apache config?

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Jay Rat]

The http response is 302.

Using blueprints. For the posts the end point is admin/faculty/
I added a logger into that method and the logger statement at the front of
the method runs bit the statements in the form processing sections never
run

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Graham Dumpleton]

At what sub path to the site are the post requests being targeted?

Sounds more like you have an issue where handler is at /subpath/, but you are 
using /subpath, and so trailing slash redirection is being tripped.

What does the Location header in responses say?

How do you have WSGIScriptAlias set in the Apache config?

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Jeremy Hawkins]

Thank you.  Removing the app.run() and changing the app to application 
(using a factory so changed app = create_app() --> application = 
create_app())

Now when running the site via apache the post requests don't seem to be 
running.  They all return the http code of 302 (found) instead of 200 like 
they do when I run the app directly in python.  I am not seeing any errors 
in any logs and the path the post is using is being formed correctly by the 
url_for function.  I'd almost say the post request aren't passing data to 
the wsgi application?

Re: [modwsgi] RHEL 7 mod_wsgi s.bind Permission denied errors

[Graham Dumpleton]

You shouldn't be invoking app.run() when hosting under mod_wsgi as that is 
trying to start its own server.

You should use a check like:

if __name__ == "__main__":


around the parts of the Flask code where the Flask development server is 
started so that it isn't run when that file is imported in a context other than 
being a main program.

What mod_wsgi is expecting is a WSGI application entry point called 
"application". See:

https://flask.palletsprojects.com/en/1.1.x/deploying/mod_wsgi/
