Some issue with interrupts during delay
by Thiede, Christoph 15 Dec '23

15 Dec '23

For the second time in two days, I was stuck in the following situation after pressing interrupt multiple times and my image froze irrecoverably: [cid:bf8bfc45-aff3-4132-9510-d8802537c162] I don't know what's going on here. Did the interrupt block a critical section that is used by a higher-level process such as the timer event loop? Unfortunately no SqueakDebug.log was produced. How can we investigate & fix this? Best, Christoph

Adapting WebUtils to use the Json class
by Tim Rowledge 13 Nov '23

13 Nov '23

At a recent SOB meeting we decided to take a look at adapting the WebUtils class to use Json instead of its own slightly idiosyncratic json encode/decode code. It seems daft to have multiple bits of code doing the same thing. The basics are trivial - change the WebUtils class>>#jsonDecode: & WebUtils class>>#jsonEncode: methods. However, we then have a few unit tests failing, almost all because of what looks like very minor disagreements about how the output of encoding something should be formatted. For example, does it in any way matter if #(#() #()) ) gets output as '[[], []]' or '[[],[]]'? I suspect not. Similarly, is it crucial whether decoding '{[}' raises Error or a Json specific Error subclass? A slightly more serious issue is whether decoding {} (that's json dictionaries) should create a Dictionary or a JsonObject. JsonObjects are quite useful because they handle being a dictionary as well as allowing use of keys as access messages. More complex is the question of the WebClientServerTest>>#testNilTrueFalse & #testNumbers tests. Should 'falsef' be an error or return 'false' etc? And is '-0123' valid json or not? As far as I can tell from trying to look up json syntax details, leading zeros are supposed to be an error and falsef should likewise. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Useful random insult:- Moves his lips to pretend he's reading.

On the rejection of Promises due to errors
by Jakob Reschke 09 Nov '23

09 Nov '23

Hi all, Tony has recently fixed our Promise implementation to make it more Promises/A+ compliant, thank you! In the discussion that lead to this fix [1], I already pointed out a difference between exceptions in Smalltalk and in JavaScript, where the Promises/A+ specification originates: Smalltalk exceptions can be resumed, while JavaScript exceptions cannot be resumed and always unroll the stack. The spec [2] says that if the onFulfilled or onRejected callback of a #then call on a promise throws an exception, then the promise returned by the #then call shall be rejected with the exception thrown. Our current Promise implementation matches this for the blocks supplied to #then:, #ifRejected: or #then:ifRejected, by catching all Errors in the blocks and rejecting the promise. But this does not allow a Squeak user to deal with exceptions in a debugger if they are signalled in the callbacks, because they are caught. The same also applies to #future promises. The latter are not really covered by the Promises/A+ spec (because it does not force the resolution or rejection of a promise that is not the result of a #then, and there is no #future in JavaScript), but futures exhibit the same problem of not being resumable in the debugger. Example: promise := 1 future / 0. "<= inspect it => promise is rejected, regardless of your actions in the debugger" Number compile: 'methodWithTypo ^ self asstring'. promise := 1 future methodWithTypo. "<= inspect it => promise is rejected, no chance to fix the misspelling of asString in the debugger and proceed" I could imagine instead letting all exceptions pass during the future or callback block evaluation, and only reject the promise if the evaluation is eventually curtailed due to the exception (be it an Error or not, think of Warning or ModificationForbidden). Example expectations: promise := 1 future / 0. "<= inspect it, press Proceed in the debugger, => promise is resolved" promise := 1 future / 0. "<= inspect it, press Abandon in the debugger, => promise is rejected" promise := 1 future methodWithTypo. "<= inspect it, fix the typo of asString in the debugger, proceed, => promise is resolved with '1'" It could be done by fulfilling a Promise about aBlock similar to this: [ self resolveWith: aBlock value ] on: Exception do: [ :ex | | resumed | resumed := false. [ | result | result := ex outer. resumed := true. ex resume: result] ifCurtailed: [resumed ifFalse: [self future rejectWith: ex]]] (Find the current implementations here: Promise>>#fulfillWith:passErrors: and Promise>>#then:ifRejected:) Note that the #outer send would only trigger handlers in the Project/World loop, or the defaultAction of the exception. The #future in front of #rejectWith: is there to avoid curtailing the unwind block context of ifCurtailed: itself if there are further errors in the rejection callbacks of the promise. The behavior of non-local exits from unwind contexts is undefined in the Smalltalk ANSI standard (just like resume: or return: in a defaultAction, or not sending resume: or return: in an on:do: exception handler at all -- VA Smalltalk interprets that as resume, while Squeak does return, for example). This implementation would also allow all deferred Notifications to pass and not reject the promise. That is because true notifications just resume silently if they are not handled. promise := [Notification signal: 'hi there'. 42] future value. "<= inspect it => Expected: resolved with 42. Actual (today): it is needlessly rejected with Notification 'hi there'" Pressing Proceed in the debugger on officially non-resumable errors (which is possible) would also not reject the promise. But further errors/debuggers are likely to appear, of which one may eventually be used to abort the execution. If the execution finishes after repeatedly pressing Proceed, then fine, resolve the promise with whatever the outcome was. promise := [self error: 'Fatal error'. 42] future value. "<= inspect it, proceed after the so-called fatal error, => Expected: resolved with 42. Actual: there is no debugger, the promise is immediately rejected." promise := [1 / 0 + 3] future value. "<= Cannot be resumed/proceeded because if ZeroDivide is resumed, it will return the exception, and ZeroDivide does not understand +, which cannot be resumed without changing the code. So you'd have to curtail the block execution => Expected: rejected with ZeroDivide or MessageNotUnderstood (depending on when you press Abandon or recompile the DoIt)." promise := [1 / 0 + 3] future value. "... or instead of changing the code or aborting, you could choose 'return entered value' in one of the debuggers, and thereby complete the evaluation of the block => Expected: resolved with whatever you entered to return in the debugger" Promises with whenRejected:/ifRejected: callbacks would no longer swallow errors, and would only be rejected when the user aborts in the debuggers, or if the future execution catches errors by itself and converts them to rejected promises, so the future promise will also be rejected. This could pose a compatibility problem for existing code. promise := (1 future / 0) then: [:result | result + 3] ifRejected: [:reason | #cancelled]. "<= inspect it => Actual: resolved with #cancelled immediately. Expected with my proposed changes: it would first show the ZeroDivide debugger, which you can abandon to resolve with #cancelled, or proceed to a MessageNotUnderstood +. If you abandon the MNU, the promise would be rejected with the MNU, not #cancelled, in accordance with the Promises/A+ spec." How to get back a catch-all->reject-immediately future under these circumstances: promise := [[1 / 0] on: Error do: [:e | e return: (Promise new rejectWith: e)]] future value. promise := [1 future + 1 then: [:n | [n / 0] on: Error do: [:e | e return: (Promise new rejectWith: e)]] future value. We could also introduce a convenience constructor for immediately-rejected promises like in JavaScript: Promise rejected: e. Or a convenience exception handler: [...] rejectOn: Error. Or [...] rejectIfCurtailed (the fullfill/then methods would probably use this as well). What do you think? As Tom Beckmann has already suggested in the last thread on the topic [1], I could also use a custom class of Promise to get just the behavior I want. But then I cannot solve it for the use of #future. At least not without patching something about the compiler in my package preamble... ;-) [1] http://lists.squeakfoundation.org/pipermail/squeak-dev/2020-April/208546.ht… [2] https://promisesaplus.com/ Kind regards, Jakob

Running Seaside in Squeak 6.1 trunk
by Tim Rowledge 03 Nov '23

03 Nov '23

I'm seeing if Seaside can load & run in the 6.1 trunk image. So far there are some issues - When trying one example operation Seaside offered to open a Debugger in-image. Initially that trapped on a deprecation warning Process>>#debug:title:full:contents: triggered from GRPharoPlatform>>#openDebuggerOn: The obvious first question is why the deprecation and what would we prefer to see used? The intent of the #openDebuggerOn: is to debug a specific context rather than simply the suspended context; so the Process>>#debugWithTitle:full:contents: seems inappropriate. One could simply fudge-in the use of ToolSet debugProcess... but there was clearly some considerable thought about this and I have no wish to trample like around like a Heffalump on double-espressos. Marcel & CT - you guys have your IDs on much of this stuff recently, what do you think? The actual error that triggered this was a dNU on #isImmediateObject, which is a moderately recent Pharo thing. It looks pretty reasonable to me (see https://github.com/pharo-project/pharo/pull/7594/commits/9688140be284c3ce2f…) and come from Marcus Denker, who is pretty good at this stuff. It's really a short-circuit on asking an object if its class isImmediateClass. The question is whether we like the idea enough to embrace it, or does one leave it to Seaside support categories? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim A hacker does for love what others would not do for money.

Inbox cleaned up
by Chris Muller 03 Nov '23

03 Nov '23

source.squeak.org had an outage last month which caused an issue related to previously processed Inbox items re-appearing once the server was restored. The reason is now well understood. I just applied a patch that should be effective in ensuring the issue doesn't happen again. As its first "test", the below were just cleared out of Inbox because they were determined to already exist (by UUID) in either /trunk or /treated. I believe this is a sound approach, and will occur automatically if/when the server has to recover again. This was an annoying and energy-sapping issue that won't dog squeak-dev again.

SqueakMap, checksums, and which version is in use
by Tim Rowledge 02 Nov '23

02 Nov '23

I'm trying to work out why SqueakMap appears to dislike my attempts to create packages. The issue appears to centre around the generation of the sha1 checksum for the uploaded package loading script. Digging around revealed the SMServer package on source.squeak.org which is dated 12 years ago. Which I *think* means we are probably looking at the image being used to provide SM being 4.3 or 4.4 one? The server code appears to rely on a couple of packages that I can't find anywhere, which is what makes me think it probably hasn't been updated since circa 2012. One aspect of the issue is that just a few weeks ago I was able to add a new version of the MQTT package. The proximate cause looks like being SMAccountPackageView>>#updateServerCache: which seems to be the place where a checksum is calculated for the uploaded file, which is then set for the 'release'. So far as I can see, that means the file that we create when making a new release, ie the script to install all the other bits. Once that is set, and the package info updated in your SqueakMap UI, loading can't succeed since the checksum simply doesn't match what is created by the current image. One of the problems is that all this SM server code relies upon HVRootView - which is a class I don't remember but is part of the very out of date HttpView2 package. Which relies upon DynamicBindings, KomServices, KomHttpServer, HTMLBuilder, some of which I can't find in any repository. That could be a fun problem. Which image version is SM based on? Can I get a copy of the SM server image to try to debug? Can we actually make a new version? Can we, should we, make a new version built on Seaside for future maintenance? Why would the checksum calculation differ across the two systems? Why do Lions? tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: PRM: PRint Money

[Whisper] [RED] Progress update
by rabbit 01 Nov '23

01 Nov '23

Hey y'all, I hope you're well. Here is an update... Sadly I am having many many errors, trying to get the stack established from the SessionConfig. I've gotten off my tush and gotten back into Whisper, refactoring like I'm crazy. Hello somebody. Here is a Hierarchy of Crypto-Network, with Layers 4, 5 & 6 segmented. Below is all the work I've been doing this month, having skipped September for other projects. My proximal focus is getting Layer4 Socket and InMemory stacks connected and talking... A concern is how to allow for SessionConfiigs for Layers 4, 5 & 6 as a spec stack, possibly negotiable (protocol, cipher, encoder)??? I subsclassed BaseConfig with TransportConfig, SessionConfig and PresentationConfig. I think a SessionConfig holds a TransportConfig and a PresentationConfig holds a SessionConfig which holds a TransportConfig. So a net stack config stack. Or something. --- Package comments since August --- MASSIVE refactoring. Working on - SessionIdentity - InMemoryListener - SessionConfig - Gate / Gozer operation. SPECed SessionConfig with protocols, ciphers and encoders. Refactor. Pruned GateKeeper and fleshed out Protocol. Extruding GhostbustersProtocol heirarchy. Extended SessionConfig to capture protocol, cipher and encoder. MASSIVE splitting Procol heirarchy out of GateKeepers, heading toward eliminating all subclasses of GateKeeper and having a provided Protocol in a SessionConfig to install into the GateKeeper of Gozer to rendezvous through dispatch to the Protocol, with the KeyMasterSecurityOps along for that ride. Working to cleanup the protocol creation / intiialization of several classes (Protocol, SessionConfig, GateKeeper). I split off GateKeeper ivars appropriately. Collapsed SessionConfig, MASSIVE Heirarchy pruning. Established BaseListener heirarchy. Reorged into Crypto-Network-Whisper. Test reorg. ELinda cleanup.
