wsgi issue in 5.0.4

[Adam Weremczuk]

Hi all,

Trying to install on Debian 11 with Apache2 and MariaDB.

After site installation and apache configuration the html doesn't render
and I'm getting:



 
  HTTP 500 - Review Board is taking a nap
(...)

Error log:

It looks like a problem with wsgi.

dpkg -l | grep -i wsgi
ii  libapache2-mod-wsgi-py3   4.7.1-3+deb11u1amd64
   Python 3 WSGI adapter module for Apache

How do I fix the error?

Adam

Re: wsgi issue in 5.0.4

[Adam Weremczuk]

I'm running WSGI in the default embedded mode:

# mod_wsgi Embedded Mode configuration
#
# This default configuration enables Embedded Mode, but you can remove
# this and uncomment Daemon Mode below.
#
# Embedded mode is simpler to configure, but daemon mode is recommended
# in production environments.

Re: wsgi issue in 5.0.4

[Laurent Marechal]

Hello,

Had a similar issue in the past. The error is kind of generic but in my
case it appeared after moving to Python3 for ReviewBoard while Python2 was
still the OS installation (thanks old RH).

The root cause was not having the WSI setup correctly. You need to update
the wsgi file with:

WSGIDaemonProcess ...
WSGIProcessGroup ...

You need to set them-up in the wsgi that you are using (reviewboard.wsgi I
think), the template created by the installation does not contain them.
Note you might get the same error if you try to run multiple wsgi
applications on the same http server.

Regards,

Laurent\

Re: wsgi issue in 5.0.4

[Adam Weremczuk]

Hi Laurent,

I have an existing and fully working 3.0.18 site. I've never had to do
anything special about WSGI, just "sudo apt install libapache2-mod-wsgi"
and copy the template config files.

I've compared 3.0.18 and 5.0.4 and key config files differ significantly
(apache-wsgi.conf, reviewboard.wsgi).

What struck me is one apache2 config line:

3.0.18:  *WSGIScriptAlias "/"
"/var/www/rebo.mydomain.com/htdocs/reviewboard.wsgi/
"*

5.0.4:  *WSGIScriptAlias "/"
"/var/www/rebo.mydomain.com/htdocs/reviewboard.wsgi
"*

Note the lack of trailing slash in the latter. Unfortunately adding a slash
and rebooting hasn't fixed my problem.

Could somebody running 5.0.X on Debian 10 / 11 care to share their working
apache2 config and reviewboard.wsgi?

Not sure how much Red Hat version would differ but no harm sharing that as
well please.

Regards,
Adam

Re: wsgi issue in 5.0.4

[Astro Jetson]

I installed on Ubuntu 20.04, Apache + wsgi.  I added logging config as 
described in the Admin Guide. the doc. I had to add 1 line to the generated 
file

This is my Apache .conf file for a 5.0.3 upgraded to 5.0.4.  Note:  I 
configured my site with an rbrd01 prefix.  ignore them.   

Hope this helps.

Re: wsgi issue in 5.0.4

[Christian Hammond]

Hi Adam,

This is not an error you should be hitting. It's hard to say what may be
triggering it, but it does seem environmental (and is before any real
Review Board code gets loaded).

Can you verify the version of Python that Review Board is installed with,
and the version mod_wsgi is using (it should be in Apache's error_log).

Also, if I could see your $sitedir/htdocs/reviewboard.wsgi, that would help.

Christian

As per the error message there is a generic runtime error being thrown
"RuntimeError:

Check below SO link which helps identify real problem.

 Hello,

 Had a similar issue in the past. The error is kind of generic but in my
 case it appeared after moving to Python3 for ReviewBoard while Python2 was
 still the OS installation (thanks old RH).

 The root cause was not having the WSI setup correctly. You need to
 update the wsgi file with:

 WSGIDaemonProcess ...
 WSGIProcessGroup ...

 You need to set them-up in the wsgi that you are using
 (reviewboard.wsgi I think), the template created by the installation does
 not contain them.
 Note you might get the same error if you try to run mul

Re: wsgi issue in 5.0.4

[Christian Hammond]

We have a lot of familiarity with this internal layer of Django and the
sort of issues that can cause it, but it’s not something that should happen
in a typical Review Board setup unless there’s something happening before
our initialization code gets to run or if there’s a system packaging issue
breaking some part of that initialization.

This will take some investigation involving copies of some files (the
aforementioned ones, and some log files and potentially Python package
listings).

Under a support contract, we can also send custom builds with additional
logging, and gather this information privately, but if anyone affected on
the mailing list is in a position to publicly provide these copies of these
files, we’ll take a look.

 Hi Laurent,

 I have an existing and fully working 3.0.18 site. I've never had to do
 anything special about WSGI, just "sudo apt install libapache2-mod-wsgi"
 and copy the template config files.

 I've compared 3.0.18 and 5.0.4 and key config files differ
 significantly (apache-wsgi.conf, reviewboard.wsgi).

 What struck me is one apache2 config line:

 3.0.18:  *WSGIScriptAlias "/"
 "/var/www/rebo.mydomain.com/htdocs/reviewboard.wsgi/
 "*

 5.0.4:  *WSGIScriptAlias "/"
 "/var/www/rebo.mydomain.com/htdocs/reviewboard.wsgi
 "*

 Note the lack of trailing slash in the latter. Unfortunately adding a
 slash and rebooting hasn't fixed my problem.

Re: wsgi issue in 5.0.4

[Christian Hammond]

To get the list in one place, this set of information will help:

* $sitedir/htdocs/reviewboard.wsgi
* $sitedir/logs/error_log
* $sitedir/logs/reviewboard.log
* Result of `pipX.Y list` (where X.Y corresponds to the version of Python
being used by mod_wsgi)
* That Python version number
* The OS and version
* Whether or not any extensions are enabled (and which ones), particularly
if there are any third-party or in-house ones enabled.

Also, we can learn a lot from running:

$ rb-site manage $sitedir shell
from reviewboard import initialize
initialize()


If that shows any errors or warnings, seeing those can point us in the
right direction.

Thanks 🙂

Christian

 I installed on Ubuntu 20.04, Apache + wsgi.  I added logging config as
 described in the Admin Guide. the doc. I had to add 1 line to the generated
 file

 This is my Apache .conf file for a 5.0.3 upgraded to 5.0.4.  Note:  I
 configured my site with an rbrd01 prefix.  ignore them.

 Hope this helps.
