1138031 - Seamonkey: reliable Version compatibility check for Language packs required

Status: RESOLVED DUPLICATE of bug 1084258

(SeaMonkey :: Build Config, defect)

Description

[Rainer Bielefeld]

Currently Seamonkey will allow installation of outdated Language pack versions without warning, and even worse, after an update of the Seamonkiy suite, obsolete Language Packs will remain and can be used without any warning. That might cause trouble as we see in "[Bug 1136767] With outdated unnecessary Language pack: Attempt to manage Feed Subscription fails with error message", "[Bug 1137600] With outdated unnecessary Language pack Browser shows xml error message instead of "timeout" for not existing web page".

Minor severity because I think most users do not use LP, but localized builds.

Hm, there is a Language Pack compatibility check, but may be it does not work reliably, or is not active in Candidates, or I simply do not understand that stuff?
The reported problem definitively does exist, but:
I launched an alternative 2.32 Seamonkey version what uses the same User Profile like my installed German Seamonkey 2.33.B1 Build 20150223174142 on German WIN7 64bit, and immediately SM recognized inappropriate 2.33 Language packs.

Steps how to reproduce:
1. German Seamonkey 2.33.B1 Build 20150223174142
2. on <http://ftp.mozilla.org/pub/mozilla.org/seamonkey/releases/2.31/langpack/>
   in Seamonkey Browser click seamonkey-2.31.ru.langpack.xpi
   And install Russian Language Pack
   Expected: warning or similar
   Actual: nothing unusual, outdated Language Pack will be installed and
           can be used.

This language pack has a maxVersion of 2.* meaning it will install in any version 2 of Seamonkey. The language packs themselves need to be fixed.

It's a build system failure, tracked in bug 1084258. I have a potential patch locally but don't get around to test it (as testing is slightly complicated) and it's unclear if mozilla-central will take the patch (as the offending code is there).
