<translate: false>?
by Andreas Raab 17 Sep '09

17 Sep '09

Hi - I haven't been following all this stuff but do we nowadays have some pragma/annotation that actually prevents the code generator to translate a particular method? The reason I'm asking is that it would be quite helpful if one could augment a plugin with utility functions that map to standard (or included) C functions along the lines of: MyPlugin>>strlen: strPtr "Simulated function strlen(). Not translated." <translate: false> ^strPtr indexOf: 0 asCharacter ifAbsent:[self error: 'core dump']. Cheers, - Andreas

Alien/Win32
by Marco Schmidt 17 Sep '09

17 Sep '09

I tried to compile a VM with the Alien-Plugin (squeaksource) under win32. I found after much tweaking (using files from John McIntosh situated under Cross/*....) an unresolved symbol "int inIoProcessEvents" . I can not locate this symbol in my sources. - Where does the symbol come from? - Ok, I found it in the newspeak-vm! Is it possible to merge these files with the current "standard" implementation ( sqVirtualMachine.[ch] )? - I have some patches to compile the vm with gcc.exe (TDM-1 mingw32) 4.4.0. - What is the way to supply patches? Thanks, Marco Schmidt

Slang newbie question
by Ronald Spengler 16 Sep '09

16 Sep '09

Hello everyone. I have a named primitive, and I need to send a ByteString to it, to be processed and returned by an external library. To get a string into Slang, should I send it #asByteArray, and would that let me treat the bytes as integers on the stack? I'm basically trying to get a char* on the other side. -- Ron

[VM-team] SerialPort updates (M7266) actions required
by David T. Lewis 16 Sep '09

16 Sep '09

Updates to the platforms code and VMMaker are needed to provide named serial port access. This is a coordinated change affecting all platforms. Following are the steps required: Dave: - Update SerialPlugin in VMMaker with new prims and 64-bit clean declarations (done - this is in VMaker-dtl.136 on SqueakSource). Ian: - Apply patch to platforms/Cross/plugins/SerialPlugin/SerialPlugin.h to declare new functions and change signatures to avoid casting pointer to int. Patch is attached (M7266-SerialPlugin.h.diff). Note, the patches on Mantis are out of date now, use this one instead. - Apply patch to platforms/unix/plugins/SerialPlugin/sqUnixSerial.c to get rid of some unnecessary type casts. I believe that you have already applied the main part of Severin's changes, so this should complete the unix updates. Patch attached (M7266-sqUnixSerial.c.diff). Andreas: - Update platforms\win32\plugins\SerialPlugin\sqWin32SerialPort.c to match the modified signatures in SerialPort.h. This prevents passing pointer parameters as ints, required for running on 64 bit platforms. - Add stub functions for four new functions (serialPortCloseByName, serialPortOpenByName, serialPortReadIntoByName, serialPortWriteFromByName) to support the the new primitives. These can just fail the primitive. Function prototypes are in SerialPlugin.h. John: - Update platforms/Mac OS/plugins/SerialPlugin/sqMacSerialPort.c, same as for Windows (see above). - I don't know how OS X handles serial devices, but you may be able consider using the Unix code at this point. Thanks all! Dave --- background --- For reference is was the suggested "to-do" list that I posted a while back. We are working on step 2 now. 1) Closure support. - Priority: High, should be done as soon as possible - All major VM distributions should support images with closure bytecodes. - Current status: COMPLETE 2) Changes to support Etoys and teaching for kids. - Priority: High, supports large educational programs. - Mantis 7266: SerialPlugin doesn't handle arbitrary nodes names - Mantis 7103: Playing sounds in linux 64 bits causes a vm segmentation fault - Current status: These require changes to VMMaker and platforms sources, all platforms effected. Changes are straightforward but must be done in a coordinated manner for all platforms. 3) Some simple updates for 23/64 bit platforms. - Priority: Low - Mantis 7236: Make AsynchFilePlugin work on 32/64 bit images and 32/64 bit unix VMs - Mantis 6828: make FileCopyPlugin work on 32/64 bit images and 32/64 bit unix VMs - Current status: These are minor updates, low priority but easy to do. Patches are available but must be coordinated for all platforms. 4) 64-bit FFI (Interpreter updates as well as FFI) - Priority: Medium - Mantis 7237: Make FFI work on 64 bit platforms - Current status: Patches are available, but additional work and testing may be required on some platforms. I consider this update important because it effects the interpreter as well as FFI itself, e.g. these changes are a prerequisite to closing out the issues in Mantis 6987: "signed32BitValueOf:, signed64BitValueOf: etc. broken".
