Project Refactorings (was: [squeak-dev] The Trunk: System-mt.827.mcz)

Marcel,

This is a great batch of improvements, and I think it will make the projects
mechanism much easier to work with in the future.

Thanks!
Dave

Have you tried it on the latest 64 bit Trunk?

I tried it on my 64 bit boot and got some errors. If you don't have a 64 bit cogspur running, I will get back to you with the errors later today.

Hi,

those changes should not affect 64-bits at all. I don't have a 64-bits image at hand.

Best,
Marcel

In reply to this post by tty

I updated my working trunk image, which is 32 bit Spur with lots of other
stuff loaded. I had no problems, but it's possible we might need to do
something with update maps, so please do report back if you see errors.

I would not expect any issues related to 64 bit image, but you never know.

Launch squeak....

Create project, enter it, exit it.

Tools->File List->projects-refactoring-may.cs

'From Squeak5.1 of 30 April 2016 [latest update: #15862] on 1 May 2016 at 6:49:39 pm'!

INSTALL button clicked.

Mouse click->World menu->Save

Debugger launches with title bar: MessageNotUnderstood: MorphicProject>>isMVC

I don't know how to print the stack trace for you, but the method that threw DNU is

CrontrolManager class >>shutDown

shutDown
Project current isMVC
ifTrue: [Project current invalidate]

Exit the debugger. Attempt to enter the project I created successfully fails and launches a debugger: MessageNotUnderstood: SoundService clas >>stop

Let me know if I can be of help.

cheers.

Re: Re: Project Refactorings (was: [squeak-dev] The Trunk: System-mt.827.mcz)

Hi, Timothy.

Your image is too old. Trunk update number is #15923 at the moment.

Do not load the change set I gave you several days ago but update from the update stream.

What happens then?

Best,
Marcel

I have been using Eliots Cog Blog here->http://www.mirandabanda.org/files/Cog/SpurImages/

Re: Re: Project Refactorings (was: [squeak-dev] The Trunk: System-mt.827.mcz)

Hi Timothy,

Dave mentioned that there may be a separate update map for 64-bit images? Even if there is, the update button should load the latest code.

Did you try updating your downloaded image? Via "Squeak" -> "Update" or by do-it "MCMcmUpdater updateFromServer".

Best,
Marcel

No, it's the same.

Hi Marcel.

Thanks. I ran Squeak->Update Squeak.

I have not loaded the changeset you provided. I assume it is included in the update.

Save image works fine.

The Project >> is MVC method exists.

Thanks for your help.

Yes, they are definitely the same. I only meant to say that if someone
/does/ find a problem doing a trunk update for some reason, then we would
probably want to check the update maps. But I did not see any problems
myself, and I see no reason for concern.
