GRVASTPlatform class>>#shutDown throws an exception

Marten Feldtmann-2
While playing with the 8.5 I have now for the second time the problem, that the method above throws an exception, when I want to leave/save the image.

In this method "ShutDownList" is nil (!).

ShutDownList is only initialized in GRVASTPlatform>>addToShutDownList:, but I have not found any senders in my image of this method.

Hi Marten,
Sounds like a bug to me. I've changed GRVASTPlatform>>#shutDown and GRVASTPlatform>>#startUp to the following to solve it:


GRVASTPlatform>>#shutDown 
ShutDownList ifNotNil: [:list | list do: [:ea | ea shutDown]]

GRVASTPlatform>>#startUp

StartUpList ifNotNil: [:list | list do: [:ea | ea startUp]].

I don't have any sender but once loaded "Platform Portabiltiy" configuration map the image can't be saved without this changes.

Regards,
Gabriel

Marten, WAServerManager class>>initialize is sending #addToShutDownList: in my image in the application SeasideCoreServer.  One more app to make sure is in your package?

Hello Thomas,

what about using the portability layer stuff without any Seaside code (e.g. Announcement did this) ????

Marten -
 
In a Seaside development image you should see 1 sender (WAServerManager); in a Seaside development image with tests loaded, you should see a 2ndd sender (GRPlatformTest).
 
That being said, it would make thing more resilient to implement Gabriel's suggestion (thanks Gabriel).

Marten, personally, I'd never have implemented the class like this.  I would have created accessors for for ShutDownList and StartUpList, and either built lazy initializers, or, more likely, set their values in the class #initialize method.  You could still set the values in #initialize without modifying any code.

That is actually how I fixed it in case 48770.  This was ancient code written in the early days of Seaside 3.0 support without a lot of thought to use of the portaility code outside Seaside (which is probably obvious since it has held up until now).
