API webservices : Extensions with numbers in their name are not shown in call List of Component Configs:

[ThomasFinnern]

Problem identified

When i want to see the configuration parameters of my rsgallery2 extension (just alive but barely working) then i get a resource not not found

When i call curl apiPath: 'v1/config/com_rsgallery2' then it responds with

{
    "errors": [
        {
            "title": "Resource not found",
            "code": 404
        }
    ]
}

I found the error in file plugins/webservices/config/src/Extension/Config.php at the end

new Route(['GET'], 'v1/config/:component_name', 'component.displayList', ['component_name' => '([A-Za-z_]+)'], $getDefaults),
new Route(['PATCH'], 'v1/config/:component_name', 'component.edit', ['component_name' => '([A-Za-z_]+)'], $defaults),

Proposed solution

The regex [A-Za-z_] should be [A-Za-z0-9_] on both lines
It has worked on my tests

Open questions

[brianteeman]

My question would be is that regex an oversight or was there a specific reason it was restricted to alpha

[ThomasFinnern]

It is checking the component name. So are component names with numbers allowed in joomla ?

The restriction is: component names could not start with number

[brianteeman]

so a better regex would be https://regex101.com/r/FYHAN9/1 ?

[ThomasFinnern]

@brianteeman Your solution would allow numbers at the end which would suffice my extension name ;-)

In this particulat point of regex using we can allow the first solution. WE expect that the component is already installed and there is no need to restrict to "no number" at the start of the of the string

[brianteeman]

from what @dgrammatiko said I am assuming that the restriction already exists preventing extensions being installed beginning with a number. Someone would need to review the code to verify that

[ThomasFinnern]

Just for info: i do remember component "j2xml" which can be found in JED

[ThomasFinnern]

So i did some tests

• Yes, J!5 installs components with starting number (com_2comptest/2comptest.xml)
• Yes a number in front of the name is not a good idea
  • A starting number in namespace is not allowed
  • A starting number in class names are not allowed

Conclusion:
There probably will be no extension with a starting number installed. Otherwise it is not prevented. So it is sufficient to check the complete name for A-z and 0-9.
