source.squeak.org timeouts
by Chris Muller 10 Nov '16

I thought the timeouts were due to the indexing, but then they continued even after it was done. Now I've identified the real cause of the timeouts and testing a fix. Thanks for your patience.

[Question] How do I add a morph to the ObjectsTool?
by H. Hirzel 08 Nov '16

08 Nov '16

Hello This is a question about how to add a morph to the ObjectsTool. Some instructions are in the class comment it is too terse for me. 1. Flaps ---------------- There is red flap on to of the screen which is shown when flaps are enabled. I'd like to add a new tool to the flap. 2. Adding a morph to the red flap ---------------------------------------------------------- The ObjectsTool manages the red flap. The class comment has instructions how to add a new morph type to the objects tool. [1] 3. Code to add to the class of the Morph to be added to the flap ---------------------------------------------------------------------------------------------- So I follow the instructions and implement a method descriptionForPartsBin ^ self partName: 'TagTool' categories: #('Text') documentation: 'A tool which offers tags for projects' in my on the class side of my class TagTool. This is not yet sufficient to have an instance of TagTool appearing in the objects tool flap. It seems that I have to call an initialisation method. 4. Question --------------------- The methods #initializeToStandAlone and #authoringPrototype are mentioned. Do I need to use them, and if yes how? Thank you for the answer in advance. Hannes ------------------------------------------------------------------------------------------------------------------- [1] I am a Master Parts Bin that allows the user to drag out a new Morph from a voluminous iconic list. Choose "objects" from the world menu, or type Alt-o (Cmd-o on the Mac). To add a new kinds of Morphs: In the class of the Morph, implement the message: descriptionForPartsBin ^ self partName: 'Rectangle' categories: #('Graphics' ' Basic 1 ') documentation: 'A rectangular shape, with border and fill style' The partName is the title that will show in the lower pane of the Object Tool. When is categories mode, an object can be seen in more than one category. The list above tells which ones. Documentation is what will show in the balloon help for each object thumbnail. The message #initializeToStandAlone creates the actual instance. To make a second variant object prototype coming from the same class, implement #supplementaryPartsDescriptions. In it, you get to specify the nativitySelector. It is sent to the class to get the variant objects. Often it is #authoringPrototype. (A class may supply supplementaryPartsDescriptions without implementing descriptionForPartsBin. This gives you better control.)

Seaside3.2 on Squeak5.1 is working well.
by Tobias Pape 08 Nov '16

08 Nov '16

Hi all I just want to report that Seaside3.2 works well on Squeak5.1 with 1422 passing tests. [1] Thanks for everyone developing Seaside and/or Squeak for taking care! Yay! Best regards -Tobias [1]: There's only one Test error because "'Seaside-Pharo-Continuation' depends on unknown package 'Grease-Pharo-Core'" which is obviously not loaded on Squeak, but gladly that does not hamper functionality.

MNU: Character>>greaseInteger when loading Seaside in Squeak Trunk
by Bernhard Pieber 08 Nov '16

08 Nov '16

Hi, I tried to load the latest stable Seaside into Squeak Trunk (latest update: #16830) using the installation instructions from https://github.com/SeasideSt/Seaside. Metacello installed fine. However, both script variants (SmalltalkHub and GitHub) result in a MNU: Character>>greaseInteger. [2] I am on macOS Sierra Version 10.12.1 and used the latest OpenSmalltalk 32bit Cog Spur VM. [1] Can someone confirm this? Should this even work, or is it recommended to stay on 5.1 when working with Seaside?

trouble with the new Mutex
by Chris Muller 08 Nov '16

08 Nov '16

Hi Eliot, I noticed you revamped Mutex earlier this year, and I'm having an issue where they're stopped even though there are no other processes inside the critical block. Those processes were background processes that ended up opening a debugger, which was closed. The Mutex is stuck and I have no internal "semaphore" I can signal anymore, it appears to be coupled straight to the VM (for better performance, I assume). Even when I restart the process in a frame totally above the method whcih even enters the #critical:, it still halts there.
