Save and restore the texts in the receiver and context inspectors when changing selection. Key the receiver text by the class of receiver. Key the context text by the method. Hence, much like the current Pharo debugger, text state stays around and can be extended as one investigates several methods in the stack.

Needs Morphic.eem.1591 (we hope cuz it ain't been committed yet).

Support for Tools-eem.915

by Marcel Taeumel (marcel.taeumel@hpi.uni-potsdam.de) at November 29, 2019 10:46 AM

Due to recurrent requests, add an #ifNil-check for the class argument in the label-formatting methods of all code holders. Still, also document the situation in a flag comment. At least, this makes this method more robust for the upcoming release. :-)

Debugger: Implements the idea of inbox Tools-eem.915, which preserves inspectors' states when toggling the selected context.

Because it is model-only, should work also in MVC debuggers. There might be a quick with #update:with: in PluggableTextView, though.

Spur:
Avoid inlining endCompaction to prevent duplication in compact.

by Eliot Miranda (eliot.miranda@gmail.com) at November 28, 2019 10:50 PM

Spur:
Make a minor refactoring to reinitializeScanFrom: to make it more readable (move assignment to firstMobileObject into scanForFirstFreeAndFirstMobileObjectFrom:).

Improve the ImageLeakChecker to bounds check objects while swizzling, and hence detect the damaged images produced by the issue 444 planning compactor bug as corrupted.

Refactor swizzleObj: to swizzleObj:in: so that ImageLeakChecker/SpurLeakCheckingSegmentManager can produce more informative diagnostics.

Improve the leak checker to first bounds check oops against the heap extent before probing the heap map. This prevents ImageLeakChecker from crashing on issue 444 corrupted images.

by Eliot Miranda (eliot.miranda@gmail.com) at November 28, 2019 10:34 PM

Fixed a fascinating bug in Planning compactor.

Sometimes Planning decides to go for a multi-pass compaction, but in one compaction it compacts it all, so that firstFreeObject is the last object on heap, on the object after firstFreeObject is outside of the heap. Planning gets confused in this case, while everything is compacted. So I changed to abort compaction in that case, since everything is already compacted.

Add FileAttributesPlugin>>primPathMax back in.

FileAttributesPlugin>>initialize uses it to store the PATH_MAX and FA_PATH_MAX, and interpreterProxy hasn't been set at that stage, so #primitivePathMax can't be used.

Slang for plugins.

Fix resultSendAlwaysFails: to include the two new failure sends, primitiveFailForFFIException:at: primitiveFailForOSError:.

As a micro optimization, if the enclosing method has type #sqInt then return the falures directly, as they're all typed as sqInt. That should save an instruction :-)

by Eliot Miranda (eliot.miranda@gmail.com) at November 22, 2019 09:21 PM

Speed up marshalling for the ProcessorSimulatorPlugins by using SmallInteger for the memory range arguments instead of Unsigned. Using the latest Slang changes this inlines a lot of code and reduces function calls to decode the range arguments. Given that the memory range arguments are always within the range of the memory byte array, SmallIntegers provide more than enough range.

More substantively use primitiveFailForOSError: to answer the failure error code, if any, on simulating.

by Eliot Miranda (eliot.miranda@gmail.com) at November 22, 2019 09:03 PM

Slang for plugins:

Generaet more efficient code for dereferencing SmallInteger type parameters in SmartSyntaxPlugins.
Avoid a stack variable access by assigning to the target variable in the validation expression, and referring to the variable in the conversion expression, e.g. instead of

sqInt v;

if (!(isIntegerObject(stackValue(0))))
return primitiveFailFor(PrimErrBadArgument);
v = stackIntegerValue(0);

generate

sqInt v;

if (!(isIntegerObject(v = stackValue(0))))
return primitiveFailFor(PrimErrBadArgument);
v = integerValueOf(v);

Allow the Cog ProcessorSimulationPlugins to use the inlined macro definitions for isIntegerObject:, integerObjectOf: & integerValueOf: even though they're external plugins (since in single steppng, marshalling performance is at a premium).

Let complex print the correct signBit of its imaginary part in case of negativeZero.

Note: the signBit are not preserved upon reinterpretation.
That's a problem of representation via arithmetic operation 1 + 2 i
because we have this
0.0 - 0.0 -> 0.0
0.0 + (-0.0) -> 0.0
(-0.0) + (-0.0) -> -0.0
(-0.0) - 0.0 -> -0.0

Fix union: and intersection: of CharacterSet

We must avoid using naive loops for huge sets that canBeEnumerated not.

An enumerationCost scale is introduced for that purpose.

The idea is that intersection: must be performed by the cheapest set, while union: must be performed by the most expensive. The most expensive eventually knows how to handle loops lazily.

When reporting VM parameters, enable formatting in the case of a parameter value that is represented as a Float rather than an Integer. This may happen if a VM parameter is defined in units of milliseconds but internally measured to microsecond precision by the VM, in which case the value may be returned as a Float in order to retain full precision.

Slang: avoid generating gcc3x-validImage.c. Including sqGnu.h only benefits something that has an interpret method.

by Eliot Miranda (eliot.miranda@gmail.com) at November 15, 2019 11:45 PM

Add an ImageLeakChecker that is only able to load an image (currently only Spur formats have been generated and tested). Do this with horrible Slang hackery to discard lots of stuff. Generate validImage.c in a stack vm directory. (N.B. this hasn't been run in the simulator yet; it'll take a little bit of work to get this to work, but in teh simulator it's easy to use the inbuilt facilities in a VM via setCheckForLeaks:)

As part of this effort clean up several methods scattered around the system so that they either are marked with <api> when they're exported, or they are always inlined, or use symbols for returnTypeC:, or have the correct return type, or no longer the sole method in a category.

Slang:
Get VMMaker to respect doInlining if imolemented by an interpreter. It used to only pay attention to a Cogit.

Enlarge and rationalize the kinds of "quick" mthods that will be inlined when doInlinign answers asSpecifiedAndQuick. Include any and all that just answer self or a constant (i.e. include those that take arguments). Include any and all that perform only a signle assignment, either answering the value or answering self.

Fix inlining of literal blocks vs inlining of two element statement lists created by the inliner. Do so by introducing a subclass of TStmtListNode called TLiteralBlockNode which has one method, isLiteralBlock and is used by BlockNode>>asTranslatorNodeIn:. Use asRootTranslatorNodeIn: to create top-level method statement lists. Better comment collectInlineList:.

Allow comma on strings to translate into ANSI C automatic literal string concatenation.

Next step is to update the stack makefiles to build validImage executables.

This update may be slow due to the package postscript processing.

Apply Kernel-mt.1278, which mergesKernel-mt.1266.

From Kernel-nice.1270, apply the BoxedFloat64>>truncated change to Float for V3.

Also update Behavior>>becomeCompact to ensure that a newly added compact class does not occupy a previously used slot in the compact classes table. This is a requirement for segment loading, as documented in the becomeCompact method comment.

Reference Levente's suggestion that ByteArray adoptInstance: 'aSting' could work in a V3 image if class ByteArray is added to the compact classes array:
http://lists.squeakfoundation.org/pipermail/squeak-dev/2019-October/204924.html

In the package postscript, make class ByteArray compact. This will allow the trunk version of StandardFileStream>>binary to work on V3, which in turn will eliminate the need for a separate V3 version of the Files package in the V3 update stream.

In SmallFloat64>>#truncated fallback, don't bother with Infinities and NaN, since all SmallFloat64 are finite, nor with Float fractionPart, since all non-integer Float value fits in SmallInteger in a 64bits image, and thus are already handled by the primitive.

It's legitimate to inject such implementation specific knowledge into this implementation specific class.

Also revise BoxedFloat64>>#truncated, mostly with comments. Dividing by SmallInteger maxVal + 1 / 2 would lead to an infinite loop in a 64bits image, fortunately this branch is unreachable then. Each time I read it, I have the shadow of a doubt ;)

Password was very specific for ServerDirectory.
Re-factor Password into a more generic password holder (usuable in other classes).
Create ServerPassword as a sub-class of Password with necessary specilizations moved down to it.
Make ServcieDirectory point to ServerPassword.

This allows us to use Password generally to store a password in memory (encoded) during a Squeak session, which is cleared out when saving. The intended use case is to not store passwords in code or in the file system - instead prompt the user at first use and cache it for the rest of the life of the session.

Quick fix for versions browser.

Note that I think that the interaction that results in selection changes should be implemented in the widgets, not the models.

Is [shift] pressed?
Is it a drag?
Is it a click on an already selected item?

All these things belong into widget code to keep model code simple. For example, I think that we should also move the logic behind range selection from MessageTrace into the AlternatePluggableListMorphOfMany. So other models (or tools) could benefit from it.

Fix issue 436 again

if msecs is usqInt, then the subtraction msecs - ioMsecs() is performed as unsigned 32bits, and can lead to high value instead of slightly negative value, which remain positive when converted to 64 bit signed long deltaMsecs...

That makes a near 48 days delay before waking up!

The expression must be evaluated with 64bits signed long arithmetic, what we obtain by declaring msecs as sqLong...

When we write C code, we must think in C language, not upper level language with exact integer arithmetic (no wrap, no overflow), that's a potential danger of Slang...

Fix the problem with small delays in old images, which occasionally break OpenSmalltalk CI as reported in issue 436

https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/436

The problem has been observed on a macos32x86/squeak.cog.v3 VM + Squeak-4.6 image still using millisecond clock to handle delays (and thus #primitiveSignalAtMilliseconds).
It happens with small delays that may be seen as slightly negative inside the primitive, and erroneously confused with a clock roll-over.

This should not happen in newer image that use microsecond clock, though I didn't perform any related analysis.
The problem can easily be triggered by this snippet (save you work first!):

s := Semaphore new.
Delay primSignal: s atMilliseconds: Time primMillisecondClock - 2.
s wait.

Now, the detailed explanations:

---------------------------------------------------

At image side, the absolute time msecs at which to wake up is usually formed by adding:

msecs := absolute_millisecond_clock1 + relative_delay_duration.

In #primitiveSignalAtMilliseconds, some time has elapsed since, and we subtract millisecond clock to retrieve the remaining duration to wait:

deltaMsecs := msecs - absolute_millisecond_clock2.

If ever the millisecond clock roll-over in between the two calls clock1 and clock2,
then we will have clock1 close to clock2 + MillisecondClockMask, and:

deltaMsecs := relative_delay_duration - already_elapsed_time + MillisecondClockMask

that is a huge delay, 1<<29 milliseconds, about 6 days!

A negative deltaMsecs means an already expired delay, it cannot happen because of rollover
(unless the VM hangs more than 3 days, case which we do not have to handle: the delay is then expired because we cannot handle such huge delays - see below).

Technically, the usage of #positive32BitValueOf: would allow passing msecs upTo: 1<<32-1, that is a huge delay (at least 1<<32 - (1<<29), about 48 days).

But how to distinguish a huge relative_delay_duration from a rollover?
We can't really. We might check if clock2 is small, and declare it's a rollover if under a threshold, else a big delay.
But there will always be edge cases when such oracle would give the wrong answer.
We could try and pass 3 arguments instead of 2, semaphore, clock1 , relativeDelay.
But are we going to need it? Not really.
With a clock that roll-over like this, the only sane thing is to cap the delay at midway:

limit := MillisecondClockMask >> 1.

Then reduce a positive deltaMsecs with centered modulo:

deltaMsecs > limit ifTrue: [deltaMsecs := deltaMsecs - MillisecondClockMask].

Only a strictly positive deltaMsecs need then to be honored as the next wake up time (nextWakeupUsecs).

---------------------------------------------------

But wait, this is only one face of the problem!

Due to current implementation of ioRelinquishProcessorForMicroseconds(),
the microsecond increment (deltaMsecs * 1000) must fit in a long.
If ever it overflows, and wrap over negated values, then bad consequences will happen via aioSleepForUsecs() and aioPoll().
This is including unresponsive runaway images spitting out errno 22; select: invalid argument in the console, as observed in bug report.
On 32bits unix VM, that further limit the maximum delay to about 2147 seconds!

IMO, it's urgent to protect ioRelinquishProcessorForMicroseconds() from such overflow,
But that will deserve another commit (it's platforms source code, not Smalltalk code).

Refactor Utilities' CommonRequestStrings: Instead of an obsolescent string, store the code itself.

This allows to benefit from senders and other refactoring tools. Also, it's impossible to compile invalid code. As you can see, I commented one line out as it contains a selector that is no longer present in modern Squeak.

This change should not affect overall performance, as #commonRequestStrings keeps caching the result.

Please note that when merging this commit into Trunk, a conflict with System-ct.1103 will be to solved manually.

Adds things for column-specific list filtering:

- backgroundColor for LazyListMorph
- optional filter-term indication for LazyListMorph
- column highlights for multi-column lists
- Character tab to cycle between columns

Note that I opted to not use the [space] key for column toggling because (a) we have to widget-focus cycling via [tab] at the moment and (b) the space character might be a valuable filter term.

Eliminate such a dependency in StdLiterals itsdelf by using a Symbol for performing literalEqual:. Remove Decompiler initialize from the comment; this method doesn;t do anything affected by VariableNode class>>#initialize anymore.

- Move log-file writing for low space to SmalltalkImage >> #lowSpaceWatcher.
- Adds Debugger >> #close, similar to Project >> #close.
- Moves #cmdDotEnabled preference check to StandardToolSet
