[OpenSmalltalk/opensmalltalk-vm] HowToBuild doesn't have to mention missing libssl (#186)
by Nicolas Cellier 18 Oct '18

18 Oct '18

Because we don't need to link against libssl. Keep the hint from Eliot for an hypothetical libfoobar.dylib missing.

FFI exception failure support on Win64 (Win32 also?)
by Eliot Miranda 31 Aug '18

31 Aug '18

Hi Windows Experts, I'm trying to have the FFI exception failure support work across the board. What I see now is that the 64-bit StackVM works, while the 64-bit CogVM does not, even though they have exactly the same exception handling machinery in place (the new squeakExceptionHandler machinery; thank you whoever wrote it, it looks very nice), and the same essential architecture for jumping back into the interpreter. I expect the issue is that the machinery for maintaining a chain through the stack and/or the stack search used in exception delivery is broken my careless management of the C stack in the Cog VM, whereas in the StackVM the C stack remains undisturbed. To reproduce the crash in the Cog VM and the successful failure in the StackVM in an updated trunk image simply - load the FFI (script attached; it does a snapshot and quit) - run the example at the end of ExceptionInFFICallError's class comment Any help on debugging this appreciated. _,,,^..^,,,_ best, Eliot

FilePlugin>>primitiveFileStdioHandles fails incorrectly?
by Alistair Grant 27 Aug '18

27 Aug '18

Hi Everyone, FilePlugin>>primitiveFileStdioHandles is responsible for opening stdio in the VM. The basic behaviour is to call sqFileStdioHandlesInto() which does the actual work and returns a mask indicating which streams were successfully opened (stdin, stdout, stderr). However primitiveFileStdioHandles regards a mask of 0, i.e. no files available, as a primitive failure: sHFAfn ~= 0 ifTrue: [(self cCode: ' ((sqInt (*)(void))sHFAfn)()' inSmalltalk: [true]) ifFalse: [^interpreterProxy primitiveFailFor: PrimErrUnsupported]]. self cCode: '' inSmalltalk: [fileRecords := Array new: 3]. validMask := self sqFileStdioHandlesInto: fileRecords. validMask = 0 ifTrue: [^interpreterProxy primitiveFailFor: PrimErrUnsupported]. This doesn't cause a problem in squeak since all primitive errors are handled by simply assuming that the stdio files can't be opened and ignoring any other errors. Pharo currently raises an unhandled exception. On Windows not having stdio available is a normal condition, so I think the correct behaviour is for the primitive to succeed, but return an array of 3 nils, i.e. successfully determined that none of the stdio files are available (this is effectively what happens in the Squeak image anyway). It would then mean that a primitive failure can be treated as something going wrong, rather than the normal (on Windows) situation of no stdio files being available. The other (minor) benefit is that at the moment there are two situations in which the primitive fails with PrimErrUnsupported: sHFAfn ~= 0 and validMask = 0. This change would make it easier to interpret the failure. Any objections? Thanks, Alistair

Indirectly I hope to help debug this. I am nearly finished with an error handling facility in the VM for FFI calls that will fail an FFI callout primitive with an error code indicating the kind of exception and the pc. This should at least stop the system from crashing and give us an improved ability to make sense of the exception; at least we'll be able to examine the arguments to the call. More details as I roll out the facility. It will require integrating some support code, rewriting FFI callout signatures to include an error code, etc. p.s.
