Please have a look at

http://code.google.com/p/metacello/

especially look at the FAQ that has two answers for your questions

http://code.google.com/p/metacello/wiki/FAQ#How_do_I_create_a_local_cache_repository_for_a_config?
http://code.google.com/p/metacello/wiki/FAQ#How_do_I_override_the_repository_for_a_config?

If you have further questions you can ask them in the metacello list:

Hi Norbert,

thank you for the links.

One question remains unanswered: is there a way to determine which .mcz files are needed without using #fetch (because fetch doesn't work behind the proxy)? I guess the answer is no, because I have no way of looking into the required Configurations that are unfetched. So I need to use a local directory and try step by step and download the mcz that is currently missing... oh my.

Or can I use a fresh image on a machine in another network to fetch all and copy the contents of my package cache onto the target machine???

Joachim,

You are on the right track with using fetch in an image that is outside the firewall ... zip up the directory of mcz files and you are off to the races.

BTW, you don't need an "empty" image if you set ignoreImage to true before doing the fetch:

version ignoreImage: true.

Re: Aw: Re: [Pharo-users] Using SqueakSource / Metacello "offline"

Why #fetch: cannot work behind a proxy? I didn't understand when he said "I can,
however, download packages using the Browser" which browser? firefox or monticello browser?

Why you #fetch: cannot go behind proxy if the proxy settings are defined in the image? There was a bug with Pharo 1.3 about this but it was fixed in latest version.

Which pharo version are you using? did you try to specify proxy settings?

cheers

Aw: Re: [Metacello] Aw: Re: [Pharo-users] Using SqueakSource / Metacello "offline"

Mariano,

I can download the mcz's using a web browser, but not from the Pharo Image. This has nothing to do with Pharo, but with the way the web proxy is set up here - it's a policy of the company. The same problem applies to any other application that's not accepted by the Proxy.

I don't have the proxy settings due to the company's policy, so I cannot tell if I have a Pharo problem.

Let's assume my machine is offline or I have too little bandwidth to download packages, but I can get them on a CD or USB stick, and I'd have the very same situation.

BTW: I am using 1.2.1 at the moment

Hi again,

I just wanted to let you know I could solve the problem with Norbert's and Dale' help.

And here is a little writeup of how I did it: http://joachimtuchel.wordpress.com/2011/07/21/pharo-how-to-load-a-metacello-configuration-into-an-offline-image/

Thanks guys!

In the meantime, I am wondering if the idea of having a tool that extracts a complete Configuration from a repo isn't helpful for more scenarios than the one I've mentioned here. In most companies, you have to hand the complete source code of a specific product version into a special version control system, so an extract of a repo that includes a complete ConfigurationOfXXX with all required packages in their specific versions is exactly what's needed for this.

yes ;)
And we need that for the distribution repository.

Re: Aw: Re: [Metacello] Aw: Re: [Pharo-users] Using SqueakSource / Metacello "offline"

Hi. I was thinking about this thread. The described solution works pretty well, but something you should be aware (I think) is that even if it doesn't fail, the generated results could be different than the expected. What I mean is that if you want to load something which at a certain point you do not make explicit WHICH version of a package to load (say you are using #bleedingEdge, or #latestVerison, or you let some defaults for project references or empty version, etc), then Metacello may find a different version in the local directory than the one that exist in the "real/online" repository.

To conclude...the resulting image will be always the same only if all versions of all packages are explicitly defined. I am right?

Thanks
