[FFI] Passing a null in argument
by Merwan Ouddane June 24, 2016

June 24, 2016

Hi, I wanted to call a function using null as argument but did not managed to do so. I tried to use an integer, but the FFI forbids it. I tried to use FFIExternalObject null, but the FFI vould not coerce the arguments. To make it work I had to duplicate the method and set 0 instead of an argument. void foo (0); Is it possible to do it the first way ? Regards, Merwan

SQLite on multiple images
by Hilaire June 23, 2016

June 23, 2016

Hi, I have a question regarding the use of the same SQLite DB from several Pharo images (all running in the same host, but likely on different cores). Is it safe in this scenario? I mean does lock on write operation correctly work? Thanks Hilaire -- Dr. Geo http://drgeo.eu

The commands are the same from classic interactive fiction games. But I think it would be nice to have a welcome message with the commands available.

File Policy
by Valentin Ryckewaert June 23, 2016

June 23, 2016

Hello everyone, i'm currently working on making Pharo able to manage if it writes on his files.I created a class which can define it, then I'm already able, for example, to define if Pharo writes on pharo.changes or not. The meaning of this is to make Pharo able to execute a script but without being modified by it, a script shouldn't let any trace of its execution on the image or on Pharo files. My problem concern PharoDebug.log, I would like to know what you prefer Pharo to do with it in the case we configured it to not write on his files (changes, source,image....). Should Pharo writes the logs in the terminal ? in a tmp file ? or just in PharoDebug.log ? Valentin
