The installer has its own TWiki::Configure::UI::getUrl() utility to dowload packages from twiki.org using a socket. This code is not aware of the proxy settings of TWiki.

I think it would be better to use the existing TWiki::Net::getUrl() instead, it is aware of the proxy settings.

(Although TWiki::Net::getUrl() is trying to use LWP, it falls back to its internal socket based code.)

TWiki stores proxy information in TWiki preferences. Access to those preferences requires a fully configured twiki, which may not be available during configure. So a prerequisite would be to remove any dependency from Net on those preferences.

Besides, I really don't want to add dependencies from the configure code on twiki core code, as it would be too easy for a minor core change to mysteriously wreck configure. It's a chicken and egg situation; configure has to be able to run with a badly broken twiki, so every dependency is a risk.

It might be easier to simply make TWiki::Configure::UI::getUrl use the proxy settings from $TWiki::cfg.

Set to Actioning, as the analysis and solution are clear.


I think we can distinguish between first time install and maintenance mode.

During first time install, settings are off, and as Crawford noticed, we should not introduce a dependency on the core (for example lib path could be incorrect.)

During maintenance mode one can assume that TWiki is running. In this mode, extensions are installed. Therefore, I find it helpful (and not an issue) that the extension installer is aware of the proxy settings.

Well, I put in support; however I have no way to test it, as I don't have any proxies. However it certainly doesn't break anything, so I think it's safe to release; it's modelled on TWiki::Net.
