==================== Summary ====================

Name: System-mt.1093
Author: mt
Time: 17 September 2019, 12:10:14.798406 pm
UUID: 5eb2c78e-ce42-654d-b764-57fc1e4d0521
Ancestors: System-mt.1092

Refactors process debugging in general, which makes MVC debugging work again:

-  adds MorphicDebugger and MVCDebugger as subclasses of Debugger to untangle debugging for those different GUI frameworks
- removes the intermediate role of UIManager for debugging purposes -- focus on Project, (Standard)ToolSet, and Process
- treat unhandled warnings the same as unhandled errors, which is through the current ToolSet
- let SyntaxError tool use tool builder
- clarify #handle* and #debug* methods in ToolSet's 'debugging' category
- adds comments to ToolSet and StandardToolSet

Strange. If I file in the cmd-dot menu, it still works as expected in recent trunk.

Best,

I just did a complete Trunk update, accepted all conflict and then re-installed your changeset. When I press cmd+dot, I can see the dialog, but when I press an arbitrary key then, my image hangs up ...

There is no DebugLog. Any ideas?

Hello Marcel

I can confirm that with your changes as of update 5.3-18978 'debug
it' in a workspace works fine.
First time for how many years? 5? 7?

Dave Lewis has put into the inbox
ReleaseBuilder-dtl.198.mcz
where he proposess

"arrange for the home Morphic project to have a parent MVC project.
The MVC project supports emergency debugging in the event of
unrecoverable Morphic problems, and will fall back on the traditional
emergency evaluator if MVC debugging fails.
"

Could this also be commited to trunk. How would a test case look like?
Some change which breaks Morphic and then an MVC project is activated
which allows to fix the cause of breaking.

Regards
Hannes

I found my mistake.

Some days ago, I had pressed the "Reparent" button multiple times on Trunk commits but did not load them ... I suppose this made Metacello to load the updates incompletely. After reparenting many packages again and merging everything manually (*sigh*), everything seems to work.

Is there any way to check that I did not miss any package? :)

Best,

Christoph

Strange. If I file in the cmd-dot menu, it still works as expected in recent trunk.

It would be great if you could create an updated version of the menu :)

Otherwise, how can I safely unload the cmdDot menu to install this commit?

==================== Summary ====================

Ancestors: System-mt.1092

Refactors process debugging in general, which makes MVC debugging work again:

-  adds MorphicDebugger and MVCDebugger as subclasses of Debugger to untangle debugging for those different GUI frameworks
- removes the intermediate role of UIManager for debugging purposes -- focus on Project, (Standard)ToolSet, and Process
- treat unhandled warnings the same as unhandled errors, which is through the current ToolSet
- let SyntaxError tool use tool builder
- clarify #handle* and #debug* methods in ToolSet's 'debugging' category
- adds comments to ToolSet and StandardToolSet

Hi Hannes!

This morning I've just run into this exact same situation: putting a halt into a method, called by a morph's #drawOn:

makes the image unusable.

The problem stems from WorldState >> displayWorldSafely: being safe only for Errors and not for other kind of

Exceptions, and Halt being only an Exception not an Error.

For a quick fix add Halt to the handled exceptions in #displayWorldSafely:

[aWorld displayWorld. finished := true] on: Error, Halt do: [:ex |

Why isn't it sufficient to test for UnhandledError instead? Otherwise, we would also need to test for Warning etc. ...
