Re: [Pharo-dev] Metacello-ToolBox-dkh.131.mcz missing on smalltalkhub?

by Sven Van Caekenberghe

This is a typical, understandable problem. I had the same problem with my http://mc.stfx.eu Monticello repos once. The thing is that http://smalltalkhub.com/mc/dkh/metacello/main should redirect to http://smalltalkhub.com/mc/dkh/metacello/main/ not just serve the same content, because else the relative links are all wrong. You can try http://mc.stfx.eu/ZincHTTPComponents to see how it should work. And yes this is a StHub bug that can be fixed quite easily. Sven On 23 Jun 2013, at 22:04, "Dale K.

I got an EOCD error loading Metacello-ToolBox-dkh.131 into GemStone during a travis ci job[2]... A month ago I reported a bug[1] and figured that the error was possibly related so I went to the site and used the http://smalltalkhub.com/mc/dkh/metacello/main/ url to look at the available packages (like I do with all of the other mcz repositories) to confirm that the package was there and that it was not corrupted ... when they all turned up giving me errors I figured that something else was broken and sent the mail ... I didn't realize that this listing has always been broken in smalltalkhub ... The EOCD error was probably just a transient problem and I was fooled into thinking that the site was truly broken ... sorry about that...

rewind, what exactly are you doing? in which image? => the listing has some issues with the relative links, AFAIK that has also been there for a while doing adding a trailing slash usually solves this problem: http://smalltalkhub.com/mc/dkh/metacello/main/ On 2013-06-23, at 21:39, "Dale K.
