  Fix linking of the libB3DAcceleratorPlugin.dylib in the Pharo build.
There is no equivalent of -bundle_loader for dylibs so use the explicit
list of undefines approach passed throguh EXTRADYFLAGS.

  CogVM source as per VMMaker.oscog-eem.2211

StackInterpreter:
Simplify and make robust display bitmap access for display update.  The old code
required platforms that needed to redraw at arbitrary times to have to access
the display bits through interpreterProxy->displayObject, decoding it each time.
There exists a small window during compaction, etc, during whiuch such access
will fail and cause a VM crash.  The new code provides four variables to
reference the display, displayBits, displayWidth, displayHeight and
displayDepth, which are assigned appropriately in the primitiveBeDisplay
primitive.  After a GC the interpreter checks if the displayBits have changed
location and if so calls ioNoteDisplayChanged:width:height:depth:
(ioNoteDisplayChangedwidthheightdepth) to inform the platform of the change
(currently all platforms implement this as a null function).

On Spur the primitiveBeDIsplay primitive also pins the display bits.

This scheme allows displayBitsOf:Left:Top:Right:Bottom: to be simplified to
updateDisplayLeft:Top:Right:Bottom:.

On Mac OS X and X11, replace access to the display Dits via displayObject with
direct access to displayBits, displayWidth, displayHeight and displayDepth vars.

Spur:
Fix cloneInOldSpaceForPinning: to handle failed allocations correctly.
Have pinObject: only clone an old space object that is 1Mb or less, simply
pinning larger objects (whioch would include the display bitmap) where it sits.

Lift the limits on Spur image segments.  There is now no limit on the number of
objects in a segment, but the classes in the segment must occupy no more than
2 ^ 21 bytes (maxIdentityHash / 2 * 8 - which allows for about 1.4 million
11 slot classes), and the segment can have no more than 2 ^ 21 out pointers
(again maxIdentityHash / 2.  Tested for simple examples. Manages to export a
project but not load it yet.

Fail if the segment store args that are mutated are either immutable or pinned.

Fix bad bug in shorten:toIndexableSize: (which could affect Scorch/Sista).
The old code for addressAfter: would be fooled by an object with overflow
slows but fewer slots than numSlotsMask.  So fix addressAfter: so it will
still add the overflow header if there is one.

Rewrite objectBytesForSlots: to follow the fixed addressAfter:.  The code
should be cleaner.

Fix checkInterpreterIntegrity in the case of the primitiveDoPrimtiive code
setting newMethod to an integer.

Fix some translation-timer warnings by tweaking storeLiteralVariable:withValue:,
storePointerImmutabilityCheck:ofObject:withValue: & primitiveGetenv.

  Hmmm, don't know why but the v3 sources with the displayBits changes don't seem
to have been comitted.  Correct that omission.
Also nuke the erroneous copy of sqVirtualMachine.h in the win32 CameraPlugin.
It is out of date and builds /must/ pick up the proper definition from
platforms/Cross/vm.

  Fix Squeak build failures on travis-ci.  All Mac builds should include
common/Makefile.app.squeak to build Squeak.app et al.  Makefile.app.squeak.cog
is a misnomer.  cog refers to the VM internals (stack vs Cog etc).
Makefile.app.squeak defines the external name of the app produced.

  Change platform sources to refer to _WIN32 & _WIN64, not WIN32 & WIN64.
Change getSystemAttribute: 1005 (the Windowing system name) to answer 'Windows'
insrtead of 'Win32' (we are stuck with answering 'Win32' on 'Win64' unless we
want to break /lots/ of image platform-dependent code).  If this breaks things
then we'll have tio revert.  But fingers crossed it is not a problem; there are
no uses of 1005 assuming other than 'X11' in a base Squeak image.

Nuke spursistastacksrc; it's a misnomer.  Sista presupposes a Cogit.

  CogVM source as per VMMaker.oscog-eem.2217

Cogit:
The code for restoring saved registers after a CallRT: did a benign iteration
in excess.

Spur:
Never inline objectsReachableFromRoots:.  Fix a speeling rorre.

SoundPlugin:
Add the Terf SoundPlugin extensions (to deal with multiple devices, their names,
volumes, etc).  Provide a nearly full implementation on Mac OS X Cocoa (inc 64
bits, but no AEC as yet).  Provide stub implementations for Unix & WIn32.  Any
one interested in win32/win64 I have the Terf C code in C++ files which needs
to be recast as C files.

Slang/FilePlugin:
Avoid remapping oops on creating directory entries in the FilePlugin on Spur by using remapOop:in:.  Change Slang to avoid creating nested #if-#else-#endif structures for nested remapOop:in:'s.  Nuke an unused configuration.

Cogit/CoInterpreter interaction:
Use a special form of sigsetjmp to avoid stack unwinding on Windows 64.

Note 1: stack unwinding is for C++ exception handling (for example for calling
destructors).  We do not need it, and it requires the presence of specific
information on stack which is not honoured by our JIT frames.

Note 2: this patch is specific to Mingw-w64. It might not work for another
compiler (MSVC/Intel/...). Someone making the Vm compile with other tools
might have to amend this #preambleCCode again.

In mingw, there is a possibility to pass a 2nd parameter to a _setjmp, and if
this 2nd argument is NULL, there will be no context unwinding. This knowledge
is extracted from these references:

Build system:
Note that gcc beyond 4.8 does not work, at least on Debian linux.

  Fix possible race condition in unix FilePlugin sqFileOpen

From original post of Monty
http://forum.world.st/Please-review-and-merge-A-commit-to-fix-race-conditions-is-sqFileOpen-buffer-overflows-in-sqUnixFilee-td4920046.html

This commit fixes race conditions in sqFilePluginBasicPrims.c's sqFileOpen() and adds sqFileOpenNew() to support a new primitive to open only new files for IO atomically using open() with O_CREAT|O_EXCL and the equivalent on Windows, failing if they already exist. This will hopefully eventually replace any in-image code that tests for a file's existence before opening it for writing and creation/truncation, a classic race condition.

sqFileOpen() issues:

Look at the current implementation. It tries fopen() with "r+b", reading/writing of an existing file, then if that fails, with "w+b", reading/writing of a new or truncated file. If the file is created and modified elsewhere between the first and second fopen(), you get unintentional truncation with potential data loss. There's also a minor race condition involving the setting of Mac file characteristics. The fix is replacing use of fopen() with the more general sys call open() and fdopen() after and proper error checking throughout.

The patch provided by Monty was much more aggressive - see PR #82
https://github.com/OpenSmalltalk/opensmalltalk-vm/pull/82
Nobody had enough energy to review all implications, thus the minimalist replacement.

  CogVM source as per VMMaker.oscog-eem.2222

StackInterpreter:
Add time primitives to answer the UTC and local microsecond clocks as updated
by the heartbeat (as the Cog VM was originally before David changed the
primitives to access the time now).  This access is much faster (of the order
of 20 nsecs per invocartion vs 450 nsecs per invocatuon on a 2.3 GHz Mac Mini).
Terf demands very fast clock times but is not concerned with fine granularity.
The primitive numbers are 245 for UTC and 246 for local.

primitiveMakePoint should fail if its /argument/ is not a SmallInteger or
Float.  Since the primitive is on Number we know the receiver is valid, and
there is no point checking it.

Fix warnings for addIdleUsecs: on WIN32/64 (must not be marked exporrt to
avoid declspec being added).

Fix display pixel reversal (for debug).  Modern implementation of displayBits
is (void *).  We can't calculate an offset (dispalyBits + n) because we don't
know the size of void! At least it fails on MSVC compiler.  So it's necessary
to convert it to char *, int *, or just sqInt.  While at it, as calculated,
the range is a pixel range (assumed on the first display line) not a word
range, but this range will be rounded to a whole word boundary.

Cogit:
Modified with Sophie K the collectCogConstituents primitive to take a boolean
parameter "withDetails". If false or no parameter, the primitive does the same
thing as before. If true, the primitive maps each CogMethod that is frameful
to an array starting with the cogMethod address followed by a mapping between
the mcpc and the bcpc instead of just the cogMethod address.

Fix the method for getting the stack pointer in Win64 ABI.  The generated
ceCaptureCStackPointers must account for the 32 bytes reserved for saving
the 4 register parameters which are allocated whatever the real number of
parameters.

Minor fix in register in branchIfInstanceOf: in SistaCogit for Characters.

Plugins:
Fix slips in the SoundPlugin code.

Win64 build.  Do not define WIN32.  Fix the win32 sqConfig.h file to work around
the clang preprocessor's failure to default undefined identifiers to 0L.

Use genMarshallNArgs:arg:arg:arg:arg: when compiling an interpreter primitive
call to allow adding the shadow parameter space on Win64.

Remove a couple of unused and dubious methods in the CogAbstractInstruction
hierarchy.  Inline arg removal to match inlining of arg marshalling, since
removal is either no or one instruction.

Fix generation of JumpR on x64.  I forgot a rex byte.  This doesn't affect SysV
because we only ever jump through ClassReg (in an open PIC dispatch) which is
RCX (1) on SysV but R8 (8) on Win64.
With the fix to JumpR a Win64 image simulates correctly (with smashing of the
shadow parameter space).

Incorporate Monty's file plugin changes: add a new primitiveFileOpenNew to open an unexisting file atomically without race condition.

Interpreter:
Fix regression in VMMaker.oscog-eem.2222.  If primitiveMakePoint no longer
checks its receiver the inlined special selector form must.  Add isFloatOrInt:
to make checking simpler.

Provide a breakLookupClassTag check on full lookup sends for debugging.

Spur:
Implement an allocated bytes tally accessible via vmParameterAt: 34 (which used
to access statAllocationCount).  Do this by counting bytes allocated in eden
plus change in usage between scavenges.  Hence maintain
totalHeapSizeIncludingBridges in SpurSegmentManager. N.B. the parameter can be
reset, e.g. to 0, via vmParameterAt: 34 put: 0, hence it can be used to measure
allocation over a span of code.

Fix a bug in calculating heapSizeAtPreviousGC which simply calculated the extentof oldSpace, potentially a huge overestimate, not its size.

Add printOopsExcept: for debugging.  Add printMarkedOops: and printUnmarkedOops:
to get round an LLDB limitation with calling printOopsSuchThat:/Except:

VMMaker build scripts:
KlattResonatorIndices does need to be loaded.  classnamed: => classNamed:

Provided the changes are optional so that the default behaviour is unchanged then no objections from me.

That's a stretch… So here's the thing:

- Opting in to highdpi ist typically necessary very early in a process startup
  (at least when you want to stay platform-independend)
- For our vm that means, the image cannot simply use a primitive to say, hey I'm high-dpi ready
  in order to change that later.
- We _can_ typically control the behavior via vm-specific files (Info.plist/ .exe.manifest)
- So, to avoid surprises because the image may not yet react to highdpi or dpi changes,
  the default vms should come with high-dpi off.
- but When we add the code soon-ish, we could switch-on by default for the next image format change that would
  nevertheless need a new vm. This would be *drummroll* sista.

So what I propose is:
- Trunk receives code updates to handle high-dpi changes very soon (i got stuff in the pipeline but not yet fully ready)
- Cog remains low-dpi (except people opt *in* the _vm_ via files)
- Sista becomes high-dpi-aware (except people opt *out* the _vm_ via files)

This would need only few changes to the code base.

Eliot, what's newspeak's stance on high-dpi?

Best regards
        -Tobias

That's a stretch… So here's the thing:

- Opting in to highdpi ist typically necessary very early in a process startup
  (at least when you want to stay platform-independend)

Which is why on Mac we can use a setting from Info.plist.  Windows is already covered.  When the issue becomes relevant in Linux we could use
- an environment variable
- an ini file, e.g. in the lib dir
- a command line switch set in the launch script

 
- For our vm that means, the image cannot simply use a primitive to say, hey I'm high-dpi ready
  in order to change that later.

Understood.  That's not what I'm talking about.
 
- We _can_ typically control the behavior via vm-specific files (Info.plist/ .exe.manifest)
- So, to avoid surprises because the image may not yet react to highdpi or dpi changes,
  the default vms should come with high-dpi off.
- but When we add the code soon-ish, we could switch-on by default for the next image format change that would
  nevertheless need a new vm. This would be *drummroll* sista.

- Cog remains low-dpi (except people opt *in* the _vm_ via files)
- Sista becomes high-dpi-aware (except people opt *out* the _vm_ via files)

All of that is fine policy, but none of it addresses the implementation, which must
- not change the default behavior
- hence select hide via some suitable mechanism.  On Mac that means a setting in Info.plist.  Hell, there might even be a standard Mac option.  e.g. from http://blog.qt.io/blog/2013/04/25/retina-display-support-for-mac-os-ios-and-x11/

    Enabling high-dpi for OS X Applications

    High DPI mode is controlled by the following keys in the Info.Plist file:

    <key>NSPrincipalClass</key>
    <string>NSApplication</string>
    <key>NSHighResolutionCapable</key>
    <string>True</string> 

So please, let's make sure that the VM continues to function unchanged for existing images.


This would need only few changes to the code base.

Eliot, what's newspeak's stance on high-dpi?

Don't know.  I'm sure they'll be happy to follow our lead.

IMO this is something that one does only on a major release such as the Squeak 4.x to 5.0 and Pharo 5 to Pharo 6 V3 to Spur transition.  The VM should strive to be backward compatible, whereas images are forwards compatible.  This allows the VM to be upgraded to fix bugs & add new functionality.  And this policy is achievable in practice.  IME, both VisualWorks' HPS and Cog and the Squeak interpreter VM (& I'm sure other Smalltalk VMs) have always provided this approach.


I don't see the providing of a setting to enable high dpi as a good reason for changing the VM version mid-stream, with all the inconvenience for users that this implies:

For users, they have to maintain two VMs and the ability to launch them plus being able to tell which is which; easier for users of Pharo launcher, but not something to be complicated unnecessarily.

For VM maintainers dropping backwards compatibility implies adding another VM to maintain and back port fixes to.  It's already costly to maintain the V3/Spur VMs (e.g. adding the allocated bytes accounting for Spur requires a guard clause to avoid impacting the V3 vm).  So we have to keep the matrix to a minimum.

I'm happy to expand the matrix for experiments that look like offering my a large future payoff such as Sista and Lowcode (& indeed Spur) and to continue to support older versions for as long as we as a community think make sense.  But we should avoid doing this wherever possible.  Resources dictate.

Hi All, Hi Eliot

I'm sorry for being a drag on progress here…

Ok. So what happens is that I have these exact lines in my commits:
https://github.com/OpenSmalltalk/opensmalltalk-vm/commit/77b57ad8decb1a5835baa23405057b72bdf39db7#diff-e6a3e805182bc4de3d9ba3acdcf20c4dR380
(and so forth…)

For now this all would be _enabled_ was this stuff being merged, which I understand does not meet your criteria of "not change the default behavior"

It is however hard to go forward without having a clear breakpoint.
- There's no way for VM and image to communicate the hi-dpi-capablitiy without it being default-enabled in the VM.
  it is simply not enable-able at runtime (without extraordinary effort) nor disable-able at runtime (without fairly-more-than-ordianry effort).
- Telling users to "please edit this file which actually belongs somewhat to the vm" is a no-go, I'd say…

Thats why I'm proposing:

- Have the High-DPI-VM-Switch DISABLED for:
        * newspeak.cog.spur
        * newspeak.stack.spur
        * pharo.cog.spur
        * pharo.cog.spur.lowcode
        * pharo.stack.spur
        * pharo.stack.spur.lowcode
        * squeak.cog.spur
        * squeak.cog.spur+immutability
        * squeak.cog.v3
        * squeak.stack.spur
        * squeak.stack.v3
- Have the High-DPI-VM-Switch ENABLED for:
        * squeak.sista.spur

So, since sista requires an Image-format-chage, this could _at the same time_ communicate that image and vm know there's HighDPI.

In any case, changing the info.plist/manifest[1] would be possible for eg, people like us at HPI when producing custom All-in-ones.

So, does that meet your criteria? if not, I'm a bit lost…

HTH

[1]: that manifest thing is funny :( So, at some point mignw/cygwin crew decided to _always_ compile a mingw-specific manifest _into the binary_.
        Which means that a custom manifest will not be used.
        Which means, since its not possible to not use that manifest in a normal way, we have to do trickery like that:

I also think this.
But the necessity burdened upon us by the os'es to decide for or agains High-DPI at a point of program execution where typically not even the Interpreter has been started means that when we don't make a cut where vm and image both know that the high-dpi capa is there, we'll never have high-dpi vms since adoption won't happen.
