Now that the simple/faster version of #take: was pushed down to ReadStream, do the same for ReadWriteStream.

Note that we still have to figure out whether we can set the readLimit from the beginning in those ReadWriteStreams.

Fixes Stream >> #take:. Unlike in #any:, we must not return nil values from #next here but the enumeration earlier. However, we can keep the fast behavior for ReadStreams in which #next: automatically stops the enumeration at the end of the receiver. See CollectionsTests-ct.361.

Supersedes Collections-ct.950. Thanks to Marcel for the fast review!

Merges latest fixes from Chronology-Core-dtl.68, after the update bug was fixed in (the kind of branch'd) Chronology-Core-mt.69.

Stop using classVar InitializeFromPrimitive before it gets removed in Chronology-Core-dtl.67.

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at July 05, 2021 06:58 AM

Merge Chronology-Core-ct.52

The 'Z' format in Java's SimpleDateFormat is documented as support for RFC 822 time zone specifications (used in email), whereas our DateAndTime class>>readFrom: is used to parse ISO 8601 format date strings. So on the face of it, this enhancement seems out of place for the Squeak parser. However, if we can believe Wikipedia, it would also be considered as a valid ISO 8601 offset specifier. Merged.

by David T. Lewis (lewis@mail.msen.com) at July 04, 2021 08:17 PM

Extends DateAndTime readFrom: to accept offset strings without colon. For example, java's zzzz format gives you such a string.

Test will be added on request.

by David T. Lewis (lewis@mail.msen.com) at July 04, 2021 08:14 PM

Cruft removal. DateAndTime no longer needs to be in the startUp list. The canInitializeFromPrimitive workaround is no longer needed. Do not use the no-argument call to primitiveUtcWithOffset, which works fine but is easier to understand in the image if we always use a single primitive interface.

DateAndTime>>#asMicroseconds and
DateAndTime class>>#fromMicroseconds:
- Rename Time class>>#localMicrosecondClock to #localMicrosecondClockValue to 1) be consistent with microsecondClockValue and 2) avoid overloading the "clock" nomenclature. It's a value, not an object!

MagmaVersionError needs to be resumable during DB version-upgrades. It's also helpful to know the dbVersion that was read from the DB.

by Chris Muller (ma.chris.m@gmail.com) at May 26, 2021 02:32 AM

- no longer necessary to #close / #open just to truncate.
- Less Delay garbage in one method.
- Let MagmaFileTraverser support a one or two-arg block. If a two-arg block is specified it is passed the graphBuffer (with access to the path of #buffers).
- Updating the DB's internal #version metafield is worth signaling a MagmaNotification.
- When running out of memory, only kill the worst non-__system session if it's NOT the only one because, in that case, it shouldn't be the cause of the memory issue.
- MagmaFileTraverser now supports either a one OR two argument "do" block. If two args, the 2nd is now the GraphBuffer, from which can be obtained the path to the current buffer (the first argument).
- Cleaner setting of loadProcess of luxury queries.
- More halts for recovery debugging.
- Better error handling of Magma version upgrades.
- RepositoryController now prints its location.
- deployment needs more work.
- Support upgrading of version 16 repositories.

Fixes a bottleneck when opening a yellow button menu on a morph that contains a very large number of subsub*morphs. On not-so-fast systems, this can be reproduced using:

self systemNavigation browseAllSelect: #notNil

On faster systems, you might need to write a small toolbuilder application to reproduce the bottleneck. I have an app with >10k list items in my image which actually blocked the image for several seconds when I yellow-clicked the window.

Fixed the problem without duplicating the logic of #allStringsAfter: by using a generator.

Complement Kernel-jar.1386 (Fix a list of termination bugs described in http://forum.world.st/Solving-multiple-termination-bugs-summary-amp-proposal-td5128285.html)

These basic tests illustrate the unwind semantics during termination implemented by the new #teminate..

Current implementation of #teminate will fail with these tests - they should accompany Kernel-jar.1386 (if accepted).

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at May 25, 2021 05:59 AM

Prevent VM crashes due to returning from #cannotReturn. The fix introduces a isRecursive variable to BlockCannotReturn to recognize an infinite loop.
#cannotReturn: loops to itself and notifies the user an infinite loop is starting. Returning from #cannotReturn: is no longer possible so that the user cannot crash the VM by accidentally pressing Proceed, by stepping over etc. #terminate can take advantage of this improved behavior.

This is a more sophisticated alternative to Kernel-jar.1404 for a discussion.

Examples like:

[^2] fork

or

[[self error] ensure: [^2]] fork

or even

a := [true ifTrue: [^ 1] yourself]
"and then do-it separately (c) Christoph:"
[a value] on: BlockCannotReturn do: [:ex | ex resume]

can no longer crash the image :)

Fix an issue when a process terminating another process is terminated in the middle of the unwind.

As a result the original process won't finish unwinding and will leave either a suspended process or a chain of unfinished contexts behind (to be GC'd).

Further improve #terminate: add comments, remove unnecessary code, fix minor issue, address Christoph's objection in [1] regarding nested errors inside unwind blocks: the following example will currently NOT execute any assignment to x:

x := ''.
[self error: 'x1'] ensure: [
[self error: 'x2'] ensure: [
[self error: 'x3'] ensure: [
x:=x,'3'].
x:=x,'2'].
x:=x,'1']

With the fix all three errors will be dealt with by opening a debugger even after abandoning the one opened on the previous error, and as a result all three assignments will be executed and the value of x will be '321'.

Revise exception handling so as to
- inactivate inner handler blocks when the exception is signalled in an outer handler
- except when the inner handler has been explicitely rearmed (see rearmHandlerDuring:)

Implementation notes: add a marker <primitive: 199> to handleSignal:, so as to detect the case when an exception is signalled within the execution of a handler block.

This induces a subtle difference:
- findNextHandlerContext might now return a handleSignal: context,
- while nextHandlerContext will only return a on:do: context (or nil).

The new workhorse for finding the proper handler is now #nextHandlerContextForSignal:
It finds and answers the (handler) context that will handle the exception, but if it finds a handleSignal: during the scan, it will restrict the search to rearmed handlers, until it reaches the handler of prior exception, at which step it continues to search normally.

Due to the scanning of inner blocks, we still need a marker for blocking re-entrancy (handlerActive temp in on:do:), but also a marker for rearmed blocks (handlerRearmed in on:do:). This can't be the same marker: an example is testHandlerReentrancy: when the rearmed inner handler pass the exception to its outer handler, the outer handler must still be inactive if it raised the Exception.

Borrow resumeEvaluating: to Cuis and use it in resignalAs:

Use many small methods in order to make the intention more explicit than with those mysterious tempAt: tempAt:put:

Small fix. On Linux, uses non-printable control characters when "map CTRL to CMD" is enabled but "map non-printable to printable" is disabled.

Due to limitations of physical modifier keys across platforms, this is not super important but it is nice to get consistent event data across platforms. I suppose that checking for non-printable control characters in keyboard handlers should be avoided to ensure cross-platform compatibility.

Another attempt at fixing #testHandlerFromAction. Unlike previous attempts, this one preserves the expectations of #testHandlerReentrancy.

The solution is to de-activate the handlers as we backtrack the stack, but to reactivate them before performing final exception handling actions (like resuming, resignalling or performing defaultAction). Indeed, those handlers must be able to handle a secondary exception raised in the course of this action.

I'd like to return to my original proposal in http://forum.world.st/The-Inbox-Kernel-nice-1391-mcz-tp5129040p5129084.html. The problem then was a bug in #outer that confused me. The bug has been fixed and the original proposal in my opinion makes sense again - to unify how the two kinds of exception return are implemented. Theoretically it's possible to change the #return definition in the future and then the two returns would diverge.

Given that we usually talk to external types or external structures (and unions ...) where #allocate: is the current pattern to prepare a list of such things, use #allocateExternal: to allocate external memory, not internal object memory.

While this conflicts with ExternalAddress class #allocate:, clients might not notice because they should usually not deal with the difference between handles being either ByteArray or ExternalAddress (or atomics). I suppose.

Let #free for handles being ExternAdress also null that address. Maybe we could establish a common prototype for a null-address?

Evaluate the new work block upon #sendNotificationsTo: in the context that sent the ProgressInitiationException signal

by Nicolas Cellier (nicolas.cellier.aka.nice@gmail.com) at April 27, 2021 11:59 AM

Fix ProgressInitiationException>>sendNotificationsTo: so that:
- the ProgressInitiationException remains inactive during workBlock evaluation
- unlesse explicitely rearmed
- active inner handlers remain active during workBlock evaluation

For the last goal, it is necessary to first resume, then evaluate the workBlock, hence usage of #resumeEvaluating:
This goes with Kernel-nice.1394 which implements this method as well as upgraded signal handling.

But if we resume, then we also reactivate current handler.
Generally, we do not want to reactivate current handler, unless explicit rearmHandlerDuring:, thus the intricated activate/deactivate dance.

- Revise use of #clearUserEdits and isUpdating
- Use the right #accept: return pattern (Boolean or False)
- Catch an edge case when you try to write something into a nested ClassBasedHelpTopic
- Mark saved methods with a #generated pragma; ask user before overwriting non-auto-generated methods to avoid discarding manual code (such as in SqueakToolsDebuggerHelp>>#usingTheDebugger)

Depends on Tools-ct.894.

Tweak browser re-use to only consider the current class if that new browser does not care, which is the case for ivoking browsers from the smart search.

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at April 26, 2021 07:56 AM

Avoid reusing a window if it is the requesting window. This is useful for the "browse" button in the system browser or even for the "hierarchy" button in the hierarchy browser if the hierarchy is the same. A common yet simple way to duplicate a window without using a halo. Since this is an explicit user interaction, it is not expected to interfere with the "re-use windows" preference. I suppose. :-)

Proposal: Revises usage and handling of primitive 19, also known as the simulation guard. Don't use it in #newProcess and variants since they don't involve any actual control logic. Instead, also show a simulation warning when debugging a control primitive (primitiveSignal primitiveWait primitiveResume primitiveSuspend). Improves integration of simulation guard warnings by signaling a Warning on the simulator stack rather than spawning a debugger on the debugged process. This also makes it easier to handle these warnings in a non-interactive context. See http://forum.world.st/Simulation-guard-lt-primitive-19-gt-crashes-the-image-td5127443.html and http://forum.world.st/Please-try-out-Fixes-for-debugger-invocation-during-code-simulation-td5127684.html for more information.

Reuploaded to resolve merge conflict with Kernel-mt.1381. Replaces Kernel-ct.1381, which can be moved into the treated inbox.

Don't hardcode Interval and LimitedPrecisionInterval so as to enable subclassing.

Note: a subclass wanting to handle limited precision bounds or increment by itself should define:

limitedPrecisionSpecies
^self.

This is not the case of TextLineInterval that only ever see Integer bounds.

Remaster Collections-nice.869 & Collections-nice.464: opimize RunArray

This should not be noticeable for Text, but as a general library, it's important for any other potential use.

- Move RunArray off ArrayedCollection which serves nothing to such subclass.
- Add the ability to remove: since it already has the hability to addFirst: and addLast:
- Fix a few missing lastIndex cache flush, and advertise about the necessity to do it in class comment.
- prefer replace: to mapValues:, as it is a more generic Collection idiom

Notice that this DOES NOT import one major change of Collections-nice.869:
the enumerating methods like #collect: will continue to iterate on each element, rather than only once per run, so as to preserve side effects.
Thus Collections-nice.869 remains in inbox until larger acceptation occurs.

Fix LimitedPrecisionInterval>>collect: it should avoid accumulating increments which also accumulates rounding errors and make collect: behavior diverge from do:.

Rather than modifying Interval>>collect:, implement the specific inexact arithmetic handling in specific subclass.

Do the same with do: and reverseDo:. This enables restoring the legacy Interval enumerations which perform only one operation per loop instead of two.

Do not check rangeIncludes: in indexOf:startingAt:. This is useless foe exact Interval, and now redundant for LimitedPrecisionInterval thanks to more carefull implementation of #size.

Distinguish questionable LimitedPrecisionInterval (those with Float bounds or step) from ordinary Interval of Integer, Fraction or ScaledDecimals.

The main interest of having a specific class is to avoid crippling Interval with Float workarounds, for the rare use case.

Explain some of the pitfalls of LimitedPrecisionInterval, and encourage alternatives in class comment, which is a second advantage of having a separate class.

Abandon fuzzy inclusion logic, which is considered to introduce more discrepancies than it tries to solve
See http://bugs.squeak.org/view.php?id=6455.
and method #testSurprisingFuzzyInclusion

Fix two other failing tests for Interval of Floats.

Fix size so that (0.3 to: 1.2 by: 0.1) includes: 1.2.
See https://github.com/dolphinsmalltalk/Dolphin/issues/1108
This makes size a bit less performant than super, a 3rd reason why a specific class is neat.

Huh, that's more comments than code ;).
