Access roles creation issues source access enabled and long list of sources

theCA

This is the scenario: multiple organizations using the same collective installation but isolated from each other.
For that purpose, as a test scenario, 5 *_sources lists where created with 65 items each belonging to the organizations:

collection_sources
entity_sources
loan_sources
object_sources
occurrence_sources

Steps:

Install new CA deb/php8 with main organization xml, removed *_sources lists, users and roles from the xml
in app.conf:

perform_source_access_checking = 1
ca_collections_acl_inherit_from_parent_default = 1
ca_objects_acl_inherit_from_ca_collections_default = 1
ca_objects_acl_inherit_from_parent_default = 1

Create clean lists xmlx and importers for those
Import lists: collection_source, entity_source, loan_source, object_source and occurrence_source. 65 item each
Create a new access role for later associate to an user, only filling the source tab
During creation, all the option boxes are in the position of Read/edit access. Hit save to save the new access role.
Go to edit the access role and now the option boxes for each source in the source tab are still in the Read/edit access until some point in which all the options are empty. See screenshot.

Options below this point are not selectable

We did several tests and depending upon the installation and the length of the description of the items the "position" from which the option boxes are empty differs. Some times that "position" falls in the object sources, some time in occurrence sources. its like it process until some point in the "page" and after that selections are not saved.
No logs or indication of errors
We also installed a new blank dublin2018, imported the lists and try to recreate the situation and its also happening but in a much more "low position" in the page

Any advice?

After some thoughts (obviously after posting this issue 😛) i went to check all the apache logs and i found this

[php:warn] [pid 336] [client 127.0.0.1:46794] PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0

After seeing that message, the issue became evident and matches with the behavior of the page being processed until some point. 😃

I went to php.ini
nano /etc/php/8.1/apache2/php.ini

Changed the value of max input vars.
max_input_vars = 1500

Then restarted apache and now looks working
systemctl restart apache2

Sorry for the post, but I hope it can be helpful to someone in the future. I also put all the commands for my future me...
