Loading Monticello Packages Programmatically

Hi,

So, in my latest robot Roz:

http://www.huv.com/blog/2009/12/roz-walking-fast-and-smooth.html

I'm going to be replacing the current embedded board with a gumstix
Overo, running Squeak. I do development on a laptop, and then push the
code changes to the Overo.

The Overo will have wifi, and thus be on my local network. I want to
push code to it by sending a command (over a socket) to a running
headless image, and have it load a specific version of code from
Monticello from a network drive, into the live running image.

Is MczInstaller the proper way to do that?

I can see running something like this on the Overo:

MczInstaller
  installFileNamed: '/mnt/dns323/monticello/package-name.XXX.mcz'

to do it. Is there a better (or more appropriate) way to do this?

Thanks,
Jon

MczInstaller is meant to load the chunk-format code inside an mcz archive without using the normal Monticello machinery. This is useful for bootstrapping Monticello its self or for loading code inside an mcz archive without having to dig around inside the zip manually.

It sounds like you want to update existing code and not just load a package from scratch, right? If so, it would better to use Monticello rather than just MczInstaller. In that case, you'd do:

MCVersionReader loadVersionFile: '/mnt/dns323/monticello/package-name.XXX.mcz'

You should download
http://ftp.squeak.org/various_images/SqueakLight/MinimalMorphic.7246.zip as
the image have the logic for deal with monticello, .sar and more.
See examples of this in http://wiki.squeak.org/squeak/6056
Now MinimalMorphic have the same logic and is 7.3 mb
It's full 3.10 compatible and with help of all I hope in the future become
3.11 compatible.

Perfect - thanks...

So I need to have full Monticello loaded into my headless image,
right?

(Which is no trouble - the machine has 256 MB of RAM and 256 MB of
FLASH, and I'm booting off a 2 GB uSD card)

Later,
Jon

Sorry, one other question.

After looking into it, it appears that it is difficult to enable NFS
on my net drive. They do however, provide an FTP server, and I know
Monticello can read from FTP-based repositories.

Programatically, what is the simplest way to do that?

Thanks,
Jon

Try something like this:

MczInstaller installStream: (ReadStream on: ('ftp://google.com' asUrl
retrieveContents))

Yes, you'll need the Monticello loaded. It would be nice to have a no-UI programmatic core-library version of MC, but there's no such beast right now.

To load from an FTP server, you'll want something like this:

| repository |
repository := MCFtpRepository
        host: 'dns323.local'
        directory: 'monticello'
        user: 'roz'
        password: 'roz'.

(repository versionFromFileNamed: 'package-name.XXX.mcz') load.

That's great - exactly what I needed.
