Re: [Pharo-project] [NativeBoost] calls to munmap always fail on OS X 10.8.2

Nov. 18, 2012


      most probably this is fine, I would not know why mmap and munmap should use
a different lookup...

It seems I found a fix. I simply copied the code from the "mmap" call over to "munmap". Can somebody (Igor?) *please* confirm that this is ok to do? My tests are green but I'm really not sure about thisâ¦
Here's the new code for NBMacExternalHeapManager>>unmap:length:
NBMacExternalHeapManager >>unmap: addr  length: len
<primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode>
"unmap memory page"
^ NBFFICallout
      cdecl: #( int (uint addr, ulong  len)  ) 
      emitCall:  [:gen | | munmap |
      	munmap := NativeBoost forCurrentPlatform getGlobalSymbolPointer: 'munmap'.
      	gen asm mov: munmap asUImm32 to: gen asm EAX.
      	gen asm call: gen asm EAX
      	]
      options: #( - optDirectProxyFnAddress )

A followup on the munmap issue:
I think it has something to do with how NativeBoost does the lookup. I looked at the way that "mmap" is called and noticed that the selector #getGlobalSymbolPointer: is being used. Resolving "munmap" with this selector succeeds while doing
NativeBoost loadSymbol: 'munmap' aName fromModule: -2
(which is what happens when the heap manager tries to call "munmap") results the stack trace shown below.
I'll keep digging...

Hi
When NativeBoost tries to call munmap to free a page (happens because a pointer I freed was the last reserved one in that page) it will throw a NBFFICalloutError (every time) because (I think) it can't find the symbol. I have absolutely no clue how to fix this so I'm in need of help.
