Description David Cook 2022-08-17 06:29:10 UTC
At the moment, Koha plugins run via Plack::App::CGIBin, which buffers responses and otherwise prevents plugins from fully leveraging the power of Plack and Mojolicious.

Bug 31380: Allow Koha Plugins to run using Mojolicious controllers

This patch adds a new mount point in plack.psgi, which makes Koha
able to run Mojolicious controllers. For example:
http://localhost:8081/cgi-bin/koha/staff/plugins/run

0a) Apply patch
0b) cp debian/templates/plack.psgi /etc/koha/sites/kohadev/plack.psgi
0c) koha-plack --restart
1) Upload Koha Plugin koha-plugin-mojolicious.kpz
2) koha-plack --restart
3) Go to
http://localhost:8081/cgi-bin/koha/plugins/plugins-home.pl
4) Next to "Mojolicious Test", click "Actions", then click "Run tool"
5) Note that the web page looks perfect
6) Note that the URL is a bit different to normal:
http://localhost:8081/cgi-bin/koha/staff/plugins/run?class=Koha%3A%3APlugin%3A%3AProsentient%3A%3AMojolicious&method=tool
instead of:
http://localhost:8081/cgi-bin/koha/plugins/run.pl?class=Koha%3A%3APlugin%3A%3AProsentient%3A%3AMojolicious&method=tool

Note: The test Koha plugin will only work with a Mojolicious controller,
but it could be easily made to work with both

Bug 31380: Add plugin hook for choosing Mojolicious or CGI script controller

This change checks for a "use_mojolicious" method in the plugin in order to
determine whether it should use a Mojolicious controller or a CGI script
controller.

Note that the check is for the existence of the method, so it is backwards
compatible with all existing Koha Plugins.
Comment 19 David Cook 2022-08-18 06:20:01 UTC
I'm pretty happy with these patches. The Koha::Mojo::Staff class will evolve over time, but I think that it's more than sufficient for running Koha Plugins now.

An additional signoff line only provides more evidence of testing. So never hesitate to add one :)
Comment 30 Marcel de Rooy 2022-08-29 12:07:34 UTC
David, just glancing over but this code looks very good.
Just thinking that Koha::Auth may be quite ambitiously named for now.
How long will we have C4::Auth and Koha::Auth side by side?
Do we actually need the 'staff' script or was it jusy easy while testing?

Thanks, Marcel :)

> Just thinking that Koha::Auth may be quite ambitiously named for now.
> How long will we have C4::Auth and Koha::Auth side by side?

Probably for a while, but Koha::Auth can be a target for any new auth work or for refactoring work. 

In Bug 31389, I've created Koha::Auth::Permissions, which contains a function to be used in C4::Auth. 

I suppose we could always use Koha::Mojo::Auth or some other Koha::Auth::* module instead of Koha::Auth.

> Do we actually need the 'staff' script or was it jusy easy while testing?

The "staff" script is for non-Plack enabled Koha instances. "api/v1/app.pl" works similarly. Although, in plack.psgi, the API gets loaded by loading that file whereas I just load the Koha::Mojo::Staff module as I think that's cleaner.

Comment 36 Martin Renvoize (ashimema) 2022-09-15 14:22:01 UTC
This one took me a little while to wrap my head around.. probably just too many bugs on the mind.

Anywho, now I have it looks great and all works as expected.. I think we'll need to carefully document it somewhere to showcase it.

Tests are passing and the changes are covered nicely.

Passing QA
Comment 37 Tomás Cohen Arazi (tcohen) 2022-09-22 12:08:28 UTC
We certainly need docs.
Comment 38 Tomás Cohen Arazi (tcohen) 2022-09-22 12:23:05 UTC
I like where this is headed to.

I think we need some more tests here, particularly for the 'staff_authorize' and 'prepare_template', unless I'm missing something. I noticed at first glance a subtle issue with __koha__user__ vs. __koha_user__ that is not caught by the provided tests.

Otherwise this is great!

It would be great (also) if you could perltidy some of this code. I usually select the code I want to tidy, and just ctrl+k ctrl+f on VScode. Please do it inline. Thanks!

Yep, can certainly do that, when I have some time.

What's the issue? I think it passed the QA tools, so that should've pointed out any perltidy issues?

Because I'm on Windows, I need to do all my editing within the Docker container, so no VScode for me. But it looks like KTD has a ":Tidy" command in Vim, so I could use that. 

But this is fresh code that I thought I was writing in accordance with the Koha Coding Guidelines? Do we need to update those or am I just out of date?

Good catch with __koha__user__. I hadn't used that return value anywhere yet. 

Following my unit tests on Bug 30962 and looking at t/Koha/REST/Plugin/Query.t, I think I now know how to write the tests you're talking about. I'll give it a go.

I think there's a problem with the perltidy vim macro in KTD but otherwise I'm open to it...

I've added a lot more tests, streamlined the code more, and resolved an issue with the authorization process.

I could probably add a couple more end-to-end tests but I've run out of time today and I'm away the next 5 days. 

Moving this back to "Needs Signoff" to get eyes on it in the meantime...

Several things the QA script complains about, all of which look like easy fixes:

FAIL	Koha/Mojo/Plugins/Core.pm
   FAIL	  forbidden patterns
		forbidden pattern: tab char (line 84)
		forbidden pattern: tab char (line 85)
		forbidden pattern: tab char (line 86)

And perltidy :)

Thanks for looking, Lucas. :)

Ran out of time today, but I'll try to get to those tomorrow.

Bug 31380: Allow Koha Plugins to run using Mojolicious controllers

This patch adds a new mount point in plack.psgi, which makes Koha
able to run Mojolicious controllers. For example:
http://localhost:8081/cgi-bin/koha/staff/plugins/run

0a) Apply patch
0b) cp debian/templates/plack.psgi /etc/koha/sites/kohadev/plack.psgi
0c) koha-plack --restart kohadev
1) Upload Koha Plugin koha-plugin-mojolicious.kpz
2) koha-plack --restart kohadev
3) Go to
http://localhost:8081/cgi-bin/koha/plugins/plugins-home.pl
4) Next to "Mojolicious Test", click "Actions", then click "Run tool"
5) Note that the web page looks perfect
6) Note that the URL is a bit different to normal:
http://localhost:8081/cgi-bin/koha/staff/plugins/run?class=Koha%3A%3APlugin%3A%3AProsentient%3A%3AMojolicious&method=tool
instead of:
http://localhost:8081/cgi-bin/koha/plugins/run.pl?class=Koha%3A%3APlugin%3A%3AProsentient%3A%3AMojolicious&method=tool

Note: The test Koha plugin will only work with a Mojolicious controller,
but it could be easily made to work with both

7) Run the above test using an unauthenticated user,
use a staff user without plugin permissions, try with a staff
user with plugin permissions, and try with a superlibrarian

8) Run tests
prove t/db_dependent/Koha/Auth.t
prove t/db_dependent/Koha/Mojo/Plugins/Core.t
prove t/db_dependent/Koha/Template.t

Bug 31380: Add plugin hook for choosing Mojolicious or CGI script controller

This change checks for a "use_mojolicious" method in the plugin in order to
determine whether it should use a Mojolicious controller or a CGI script
controller.

Note that the check is for the existence of the method, so it is backwards
compatible with all existing Koha Plugins.
Comment 52 David Cook 2023-11-07 02:31:44 UTC
Since writing this plugin, I've done more work on plugins, and maybe it's not a good idea.

I mean the framework for using Mojolicious is still good but maybe not the stuff for plugins...

For instance, opac/opac-account-pay-return.pl calls the "opac_online_payment_end" and passes a CGI object as the controller. There's no way of really making that a Mojolicious controller.

So this would really only work for "report" and "tool" plugins.
Comment 53 David Cook 2023-11-07 02:38:47 UTC
Despite my efforts to save these patches just now... it's probably best to mark this as RESOLVED WISHLIST.
