JSON into Trunk? =)
by Marcel Taeumel 16 Feb '22

16 Feb '22

Hi all! I think it would be nice to have JSON as part of Squeak Trunk. This would make parsing the content of web requests easier. Recently, I got lucky to find the last-modified date in the HTTP header for the public TravisCI badge. But usually, one would have to query the official endpoint/API to then get XML or JSON content. http://www.squeaksource.com/JSON What do you think? The project is + Self-contained + Stable since 2016 + Not that big o Adding the extension #jsonWriteOn: to the system Latest maintainers seem to be: Hannes Hirzel (hjh, 2010) Levente Uzonyi (ul, 2010) Tony Garnock-Jones (tonyg, 2016) Fabio Niephaus (FabN, 2016) Best, Marcel

Solving multiple termination bugs - summary & proposal
by Jaromir Matas 16 Jan '22

16 Jan '22

Hi All, here's a summary of bugs in the current termination procedure: 1. #isTerminated and #isSuspended fail to report correctly - in [1] 2. active process termination bug causing an image crash - in [2] 3. nested unwind bug: skipping some ensure blocks - in [3] 4. likely a bug: a failure to complete nested unwind blocks halfway thru execution - also in [3] 5. Christoph's discovery: a failure to correctly close the debugger in case of error or non-local return in unwind - in [4] 6. inconsistent semantics of unwinding protected blocks during active vs. suspended process termination (not reported yet - different sets of unwind blocks are executed depending on whether a process terminates itself or whether some other process initiates its termination; the proposed solution unifies active and suspended process termination and is consistent with Visual Works semantics (and goes beyond)) [1] http://forum.world.st/The-Inbox-Kernel-jar-1376-mcz-td5127335.html#a5127336 [2] http://forum.world.st/A-bug-in-active-process-termination-crashing-image-td… [3] http://forum.world.st/Another-bug-in-Process-terminate-in-unwinding-context… [4] http://forum.world.st/Bug-in-Process-gt-gt-terminate-Returning-from-unwind-… I'd like to propose a solution - a rewrite of #terminate - addressing all of the above issues. Main points of the solution are: (i) why differentiate active and suspended process termination? I propose to unify the two: to suspend the active process and terminate it as a suspended process. As a result the semantics/outcome of the unwind algorithm will be the same in both cases. Fixes 2 and 6. (ii) the above leads to a susbstantial simplification of #isTerminated - a process is terminated when at the last instruction of its bottom context. Fixes 1. (iii) unwind algorithm for incomplete unwind blocks is extended to execute the outer-most instead of the inner-most incomplete unwind context. Fixes 3 and 4. (iv) indirect termination via #popTo is replaced with a analogue of #unwindTo: using Eliot's ingenious #runUntilErrorOrReturnFrom: the same way as in (iii). I'd very much appreciate if someone commented this part because I haven't found any clue why the indirect termination has implemented using #popTo and not #runUntilErrorOrReturnFrom. Fixes 5. I enclose a set of examples used to compare the current Squeak semantics with the proposed one (and with VW) that can be used to build test cases. Here's a commented code. I'll be happy to provide detailed step-by-step guidance if you find this whole idea interesting and worth implementing. I'm convinced at least parts of the proposal should be integrated as simple fixes of the current bugs. Thank you for your patience if you're still reading :) Any feedback extremely welcome.

Catching (Error, Warning, Halt) is a common pattern to be (relatively) sure that no debugger will occur during an operation. For related usages, see Morph >> #fullBounds, WorldState >> #displayWorldSafely:, and many other places. IMO it is no desired behavior that the whole test execution, i.e. in a TestRunner, is interrupted because any method under test contains a halt or raises a DeprecationWarning, for example. Instead, the test should be listed as red. For a similar discussion, see https://github.com/hpi-swa/smalltalkCI/issues/470.

deprecation policy
by Nicolas Cellier 10 Jan '22

10 Jan '22

Hi all, 60Deprecated refers to WindowColorSpec But WindowColorSpec was in 51Deprecated which is no more in the update map. So we must clarify a bit... Deprecated(n) cannot refer to Deprecated(n-1), otherwise we can never remove the deprecated packages... I suggest we move WindoColorSpec from 51Deprecated to 60Deprecated and emit a new version for each of these... Thoughts? Nicolas
