Description

We need to add an option to the interface of the extension to allow selecting php 7.4 - a radio button would be ok.

Then we need to work on the backend, basically adding to modules/profile/files/trafficserver/x-wikimedia-debug-routing.lua some lines to add PHP_ENGINE=7.4 to the cookies in the request if we find the relevant string.

I'd appreciate another pair of eyes on the patch I uploaded. I cannot get the debug header to actually contain anything but the debug host; none of the other options such as readonly have any effect. This was already like this in 2.4.6, so it's not something I did.

Instructions on how to test it are in the readme.

I've checked the other three, and those appear to work fine, e.g. inline profile, XHGui, and Verbose log. There appears to be something funky with the readonly option indeed.

Hi! When do you think we can make a release of the extension? What will be sent over the wire?

Submitted to web stores yesterday (T314108) and is live now. It sets a php74 attribute, similar to other XWD attributes. E.g.

X-Wikimedia-Debug; backend=; php74
X-Wikimedia-Debug: backend=mwdebug1001.eqiad.wmnet; php74
X-Wikimedia-Debug: backend=mwdebug1001.eqiad.wmnet; log; php74; querysort
