You should do it only on demand (like $mediawiki is created lazily).

Space after ",".

This line looks suspiciously similar to the previous one. Do you need
another variable for the same value?

Space after "," (many more instances after).

Indent the body of {} please.

Broken indentation.

Does this work on wiki configured in foreign languages, like french that
has Spécial:Téléverser instead?

This queries the wiki to get the last revision id. The existing code (to
deal with page) could get this from the response of the API to the edit
request, like this:

		$newrevid = $result->{edit}->{newrevid};

Your version is much more inefficient (many requests each time you
upload a file), and has a race condition (what happens if someone else
creates a revision at the same time?). Isn't there a better way?

It's not a matter of version, it's a matter of configuration.

> +sub get_reviId_filepage() {

Strange name (two consecutive i?). If this function fetches the last
wiki revision, why not call it get_last_mw_revid or something like this?
