Planet Squeak Code

Fix a crash in recursive invocations of primitive 118, [receiver:]tryPrimitive:withArgs:. THis is a bit of a hack. The primtiive failure wsill not be unwound correctly. We may have to revisit this, but at least the simple case of
6 tryPrimitive: 118 withArgs: {9. {}}
no longer crashes the VM.

This is tye justification for the many changes in VMMaker.oscog-eem.3103. WIthout those changes the real VM crashes while the simulator carried on without identifying the null pointer violation; an unacceptable infelicity.

SpurMemoryManager simulation:
Implement a null pointer trap by not including the first word in simulated memory. So instead of adding one to the reduced memory address in SpurNNBitMMLE[Co]Sim,ulator???>>longAt:[put:] et al, just divide by the word size. Hence 0 to wordSize - 1 map to zero, which is an invalid index.

This has pervasive effects in the surrogate classes. So refactor them, adding a new class CogSurrogate. Implement their code generators in the CogSurrogate hierarchy, invoked from the relevant classes in the VMStructType hierarchy. Have these surrogates access memory via objectMemory, rather than accessing an objectMemory's memory directly. This implies signed/unsigned conversions in places.

Although this is an enormous amount of work for a little change, it is worth it. Thie simulator has been missing null pointer references for ever. Not good ;-). And at least we get rid of the horrible little CogitFaker class which was used only to check the location of the cpicHasMNUCaseOrCMIsFullBlock flag bit.

Resolve, apparently reasonably correctly, the #addPaneHSplitterBetween:and: issue

by tim rowledge (tim@rowledge.org) at November 20, 2021 11:11 PM

Fix a bug: when debugging things like this:

[^2] ensure: [Transcript cr; show: 'done']

if we step into the protected block [^2] and then step over ^2, we incorrectly get a BlockCannotReturn error.

This is an alternative proposal to Kernel-jar.1421 (and Kernel-jar.1413); the solution remains the same but it attempts to present a cleaner code (trying to address Christoph's objection in [2] and [3]).

The bug is described in detail in Kernel-nice.1407 and discussed in [1] and most recently in [2] and [3]:

November 20, 2021 11:22 AM

Add a memoryOffset variable to the ProcessorSimulatorPlugin(s). Hence the SpurMemoryManager/ObjectMemory simulators are free to discard the first work in their memory array to implement a null pointer trap.

Correct an infelicity in the simulation of the ProcessorSimulatorPlugin(s) by passing the size of the argument, not the size of the simulator's memory, through to the real plugin, i.e. refactor rawPrimitive[Run|SingleStep]InMemory:offsetBy:minimumAddress:readOnlyBelow: to rawPrimitive[Run|SingleStep]InMemory:size:offsetBy:minimumAddress:readOnlyBelow:

CoInterpreterMT: implement "negative binding", binding a process to any thread /other than/ a specific thread. This is a much more elegant solution to the "don't tie up the event receiving thread" issue than using a separate, non-Smalltalk thread to receive events (and in fact that solution can't work because (some time in the near future) events must be deliverable as callbacks).

Merges two tests that are no-longer to do.

October 20, 2021 11:09 PM

Tests nullable closures that are introduced in Regex-Core-ct.70.

Note that #testHenry142 and #testHenry146 will time out until Regex-Core-ct.62 is loaded (fixes copying of cyclic RxmLink structures).
The second match in #testLookaroundNullable currently fails for the same reason as #testOptionalLookbehind2; see Regex-Tests-Core-ct.14.

October 20, 2021 10:36 PM

Adds support for nullable closures and eliminates the eponymous error message. Expressions like these are now parsed and matched correctly:

(a|b?)*
(a*)*
(a+){,3}
()*|
(?<=a)?

This design decision is inspired by the behavior of several existing regex implementations (such as Python's regex module, the ECMAScript standard, .NET, or Java). While some of the examples from above might be pretty useless in practice, especially the first example - conditional nullability - was a serious limitation in many cases before. See regex101.com and https://www.regular-expressions.info/ for further information.

Implementation summary:
Matching nullable closures is non-trivial as, considering the second example from above, the matcher might try to match the inner piece again and again while capturing empty strings for every repetition of the outer piece. We avoid such infinite loops by remembering all open branch positions temporarily while matching a certain path of links in the matcher. If an open branch is reached again at the same position, a match will not possible and is refused immediately. In the parser, #signalNullableClosureParserError and all sends to it are eliminated or replaced by finer-granular validity checks.

Depends indeed on Regex-Core-ct.63 to avoid another merge conflict in the parser.

October 20, 2021 10:26 PM

Fixes #testOptionalLookbehind2. It still fails, but this time for the real bug in the matcher instead of a lowercase slip in the test.

October 18, 2021 08:09 PM

Fixes #requestNextReleaseVersion to always assign both NextMajorVersion and NextMinorVersion. Since the 5.3 release, only the latter was initialized, causing "ReleaseBuilder versionString" to answer "Squeak6.3" without this patch.

Implements #cleanUp: on ReleaseBuilder. Also resets both variables immediately via postscript.

October 18, 2021 05:49 PM

Fixes CompiledMethod >> #(reads|writes)Ref: to honor nested code literals (i.e. CompiledBlocks) correctly. The literal index needs to be determined for every literal individually.

With this patch, also the "stores into"/"assignments..." button in tools works again. For example, browsing assignments to the variable NextMinorVersion in the class ReleaseBuilder does not report "no stores into" any longer.

For reference, the first attempt of refactoring these methods was made in Kernel-mt.1244.

The most significant 14 bits are the threadId; if negative, this means "bind to any thread other than the negation"; if positive, this means "bind to this thread". The least significant 14 bits are the thread the proces is affined to (temporarily bound to). If zero, the Process is not temporarily bound.

vnb := (best name subStrings: '-') second asInteger.
vne := (each name subStrings: '-') second asInteger.
vnb > vne
ifTrue: [best]
ifFalse: [each]].

Add primitiveFailFor:withSecondary: to allow the ThreadedFFIPlugin to fail with the new PrimErrFFIMarshallingError and its own specific marshalling error code as a parameter.

StackInterpreter: make sure primitiveCallout is loaded only once from SqueakFFIPrims. C initializer semantics may have meant it was being reloaded every time.

Changes to accompany VMMaker.oscog-eem.3075

by Eliot Miranda (eliot.miranda@gmail.com) at September 28, 2021 05:50 PM

StackInterpreter:
Major change to debug printing so that the platform error handlers can print the call stack to a specific FILE * stream, not simply hack stdout via pushOutputFile.

transcript now becomes a FILE * inst var of StackInterpreter; all printing goes to this file. withRedirectedOutputTo:do: is used to switch it to another stream and implement printCallStackOn: et al. See protocol "debug printing redirected".

Platform changes to follow.

P.S. this commit may be broken because it will be followed by one for ThreasdedFFIPlugin failure codes which is saved for the subsequent commit using the Ignore facility.

Merge. Adds dependency on NumberPrinter in Repository: http://ss3.gemstone.com/ss/NumberPrinter/

Name: Printf-nice.16
Author: nice
Time: 28 September 2021, 2:26:09.620217 am
UUID: 396fb662-1c87-464a-800f-cd7f3bd59d21
Ancestors: Printf-eem.15

This version of Printf use the (Versatile)FloatPrinter package so as to correctly print the float with %aefg.

Note that the output may still differ from C if many digits of precision are requested, because FloatPrinter uses an algorithm to print the shortest float that could be re-interpreted unchanged (roundtrip conversion). Hence it may change not significant trailing digits into zeros.

Example that prints trailing zeroes instead of exact value:
'%.57f' printf: 0.1.

One can retrieve C-like behavior by printing the (true) fraction though:
'%.57f' printf: 0.1 asTrueFraction.

But one shouldn't do that for hex '%a' format, nor for exceptional floats (inf/nan), so it's not a general solution.

Note that current implementation fails to render the requested case for the moment (operator aAeEfFgG). It could be easily solved though.

Note that C printf also force the plus sign when printing a Number rightFlush:
'%+5d' printf: 23.
If we don't want a +, we can use the space specification instead which forces a space:
'% d' printf: 23.
Previously, those rules were not honoured correctly.
To solve this, we introduce a plusSign inst. var., which is assigned by space and rightFlush (+) flags.
A possibly bad side effect, is that turning an agnostic format descriptor into a number format descriptor, would force the plus sign.
To avoid this side effect, the flush inst. var. is now initialized to a neutral #yourself.
Fortunately, alignment is either left or right, so testing == #leftFlush is always discriminating enough, no need to test for #rightFlush or #yourself when rendering.
Testing == #rightFlush is only ever useful for printing the descriptor itself.

Revised suggestion for adding 16 & 32 bit character types that preserves backwards compatibility.

Complements/prepares FFI-Kernel-mt.220. Integrates FFI-Pools-eem.39 from inbox.

16-bit and 32-bit character types will simply get type codes 14 and 15 to remain backwards compatible within plugin version 1.

Sketches possible #initializeTypeConstants_v2 for plugin version 2, using 5 bits instead of 4 bits for encoding type codes.

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at September 16, 2021 09:47 AM

No signed character types anymore. "char" and "uchar" (and "schar") have all the same type codes for the plugin.

Avoid dependency on type codes in #isCharType and #isIntegerType and #isSigned to support different plugin versions.

Minor fix in #initializeAtomicTypeCodes when removing (un-aliased) atomic type names (here: char8_t, char16_t, char32_t -- these are now aliases for uchar8_t, uchar16_t, uchar32_t).

Revert Fraction>>#= so that (Fraction numerator: 5 denominator: 1) = 5. Having this be false is as wrong as having 5.0 = 5 return false, IMO.

Kent Beckian purposefully plenk'd pretty printing.

Revert the changes introduced in Symbol>>#= (via Collections-nice.820) because it breaks the classic Proxy pattern.

Fix a dangerous part of the Chronology API.

- DateAndTime utcMicroseconds: Time utcMicrosecondClock offset: 0 looks reasonable, but it's very not. Notice how it's off, silently, by 68 years!!!
- Deprecate Time class>>#utcMicrosecondClock. Only soft-deprecate it for now due to its use in Kernel and Network packages. Will update them as needed.
- Replace it with Time class>>#primMicrosecondClockValue, where "prim" at least indicates implementation-specific properties may be present.
- Complement legacy Smalltalk-80 protocol, and expose the new microsecond-level precision in the VM for users with:
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!
- Remove unused DateAndTime class>>#millisecondClockValue.

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

- 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.

- Use Magma17To18Upgrader in this package to upgrade Magma databases from 1.62 to 1.63.
- The generic MagmaUpgrader superclass now has a 'log' to capture the various Notifications.
- It also includes a #enumerate:check:repair:perform: convenience method for invoking a MagmaDataRepair, as well as methods for doing different things for an upgrade.

- Trade #crashVm for #killVm, which uses linux command to "kill -9" the PID of the running Squeak vm.

After two days of debugging: Revert MaServerLocation>>#isLocalHost to its 2009 version. The 2018 "fix" was put in due to a VM bug which was then later apparently fixed.

Capture the series of messages sent to a MaBehaviorFinder into its 'log'. This way, a "logical" definition of behaviors, useful for systems that evolve.
Inspired by the GraphQL framwork for Squeak. It has a "SmalltalkEngine" which is intended to expose Smalltalk via GraphQL.

Since reverting Collection>>#asCollection back to Brent's original implementation, there were no issues experienced until MaxTrader needed to use Array's of Strings as input to a permutation, so that particular functionality that was lost is now restored by this new #asCollection override in String.

Eliot felt the need to rename my #addNewElement: to #ifAbsentAdd:. Make the same to MaIdentitySet.
