Name: ToolsTests-jar.109
Author: jar
Time: 19 December 2021, 6:47:42.938686 pm
UUID: 62c82ef6-3dee-aa46-9eba-de210be19a62
Ancestors: ToolsTests-ct.108
supersede ToolsTests-jar.105
modified tests to reflect the change in the default "close" debugger action to #terminateAggresively introduced in Kernel-ct.1434 (ct);
"standard" termination of the debugged process remains available in the debugger window menu; these tests explore this form of termination of the debugged process (i.e. not via the "close" button).
Please remove ToolsTests-jar.105 from the Inbox

- I am an SUnit Test of BlockClosure and some of Context's simulation machinery'. See also MethodContextTest.

- aBlockClosure - just some trivial block, i.e., [100@100 corner: 200@200].
- homeOfABlockClosure - the home context of the block

- NOTES ABOUT AUTOMATING USER INPUTS
-
- When executing non-interactive programs you will inevitably run into programs (like SqueakMap or Monticello installation packages -- and other programs, to be fair) that require user input during their execution and these sort of problems shoot the whole non-interactiveness of your enclosing program.
-
- BlockClosure helper methods have been made available and tests of these helpers are provided in this class to demonstrate that it can intercept PopUpMenu and FillInTheBlankMorph requests for user interaction. Of course, PopUpMenu and FillInTheBlankMorph were modified to first signal a ProvideAnswerNotification and if someone handles that (e.g. the enclosing block) then the user interaction will be circumvented and the provided answer of the enclosing block will be used. The basic syntax looks like:
-
- [self confirm: 'Install spyware?'] valueSupplyingAnswer: #('Install spyware?' false)
-
- There a few variants on this theme making it easy to provide a literal list of answers for the block so that you can handle a bunch of questions in a block with appropriate answers.
-
- Additionally, it is possible to suppress Object>>inform: modal dialog boxes as these get in the way of automating anything. After applying this changeset you should be able to tryout the following code snippets to see the variants on this theme that are available.
-
- Examples:
-
- So you don't need any introduction here -- this one works like usual.
- [self inform: 'hello'. #done] value.
-
- Now let's suppress all inform: messages.
- [self inform: 'hello'; inform: 'there'. #done] valueSuppressingAllMessages.
-
- Here we can just suppress a single inform: message.
- [self inform: 'hi'; inform: 'there'. #done] valueSuppressingMessages: #('there')
-
- Here you see how you can suppress a list of messages.
- [self inform: 'hi'; inform: 'there'; inform: 'bill'. #done] valueSuppressingMessages: #('hi' 'there')
-
- Enough about inform:, let's look at confirm:. As you see this one works as expected.
- [self confirm: 'You like Squeak?'] value
-
- Let's supply answers to one of the questions -- check out the return value.
- [{self confirm: 'You like Smalltalk?'. self confirm: 'You like Squeak?'}]
- valueSupplyingAnswer: #('You like Smalltalk?' true)
-
- Here we supply answers using only substrings of the questions (for simplicity).
- [{self confirm: 'You like Squeak?'. self confirm: 'You like MVC?'}]
- valueSupplyingAnswers: #( ('Squeak' true) ('MVC' false) )
-
- This time let's answer all questions exactly the same way.
- [{self confirm: 'You like Squeak?'. self confirm: 'You like Morphic?'}]
- valueSupplyingAnswer: true
-
- And, of course, we can answer FillInTheBlank questions in the same manner.
- [FillInTheBlank request: 'What day is it?']
- valueSupplyingAnswer: 'the first day of the rest of your life'
-
- We can also return whatever the initialAnswer of the FillInTheBlank was by using the #default answer.
- [FillInTheBlank request: 'What day is it?' initialAnswer: DateAndTime now dayOfWeekName]
- valueSupplyingAnswer: #default
-
- Finally, you can also do regex matches on any of the question text (or inform text) (should you have VB-Regex enhancements in your image).
- [FillInTheBlank request: 'What day is it?']
- valueSupplyingAnswers: { {'What day.*\?'. DateAndTime now dayOfWeekName} }

- A Mutex is a light-weight MUTual EXclusion object being used when two or more processes need to access a shared resource concurrently. A Mutex grants ownership to a single process and will suspend any other process trying to aquire the mutex while in use. Waiting processes are granted access to the mutex in the order the access was requested.

==================== Summary ====================
Name: KernelTests-jar.433
Author: jar
Time: 7 June 2022, 6:24:58.053964 pm
UUID: b2a35851-6470-a643-9f6f-e939501100b6
Ancestors: KernelTests-mt.425
Bundle together all new Process and Semaphore tests from:
KernelTests-jar.431, 432 (multiple termination and NLR)
KernelTests-jar.429, 430 (unwind errors test)
KernelTests-jar.428 (more tests)
KernelTests-jar.426, 427 (priority before suspendedContext)
Complements Kernel-jar.1476 (updated terminate with sync) and Kernel-jar.1473 (priority set before suspendedContext).

One more Process test; this verifies that if a terminating process gets stopped and terminated again, all unwinds execute correctly and the original terminator process terminates as well.
Such a situation may occur e.g. when a terminating process encounters an error and opens a debugger (or calls another recovery machinery). In such case it's legitimate to terminate the terminating process again (by closing the debugger or as a termination by another recovery tool).
Note: it's a different situation than in 'testTerminateTerminatingProcess' where the second termination is invoked "too early" and may cause unpredictable outcome - that test is still WIP.
Add testTerminateWithDelayInUnwind to the expectedFailures for the moment. Adopting #teminate for that scenario is WIP.

More Process and Semaphore tests. These explore boundary scenarios like termination of process with suspendedContext = nil, or with just a single ensure context, or with two ensure contexts directly on top of each other, or a process running at the highest priority etc. These scenarios bit me when working on #terminate so let's share them.
One of the tests: 'testTerminateWithDelayInUnwind' will require a small update of #terminate I'll be sending later today. A process that invokes termination of another process is expected to wait until the terminating process finishes unwinding itself. A delay or yield inside unwind blocks may cause control be handed over to the original process which may be assuming the termination has finished. This scenario will have been fixed in the above mentioned #terminate update.
