Writing files - Mac OS or Pharo change?

by Arturo Zambrano

Hi All, I'm porting (no big changes) code from pharo 4 to pharo5. In (*) the resulting file handle is nil. Not sure why, may it be something related to the recent Mac OS X upgrade to Sierra? The same code was working with Pharo 4 on El Capitan. The calling code is a Fuel serialization. openForWrite: writeMode "Open the file with the given name.

Re: [Pharo-users] Announce: whisper updated

by Robert Withers

Though the whisper code is currently language inter-inoperable, the latest code is being hosted on gitlab with International Rabbits, as voix-basse-mourde. Here is the code: https://gitlab.com/des-lapins-internationale. If you would like to help, Java could be brought forwards adding PBEReader/PBEWriter, dataEncoding negotiation, SecureSessionSpecification with filtered cryptoProtocolNames, dataEncoderNames, scopeMaker and the traceDomains to parameterize the server behavior. On the Smalltalk side, Whisper_json, Whisper_magma and Whisper_fuel could be implemented. Matching JSON on the Java side. FEC Reed-Solomon could be tested and repaired (it's broken). kerkkutatti is the Java code for remote promises and has the Smalltalk porcini code too. With Whisper's new SecureServerSpecification, the injection of a scopeMaker and encoder is all the config after push into the stack. Lots of work there on both sides, to get them talking. If you want to help, have a beer and I'll match you, let me know what you want to work on and I can add you as a gitlab rabbit.
