[Pharo-project] question about keymapper
by StÃ©phane Ducasse Oct. 22, 2011

Oct. 22, 2011

Hi guillermo Can I with keymapper have a tool that define a set of binding that overrides the one defined globally? This way we could unify all the system to use only one mechanism for keymapping. Stef

Both InputEventFetcher and InputEventPollingFetcher are in the lists, going back to at least 1.3 Can't have that. Probably got there when switching InputFetcher (IE a _long_ time ago) due to being careless with receiver of #install / #deinstall... InputEventPollingFetcher should be removed. Cheers, Henry

[Pharo-project] Too many semaphores, image blocked
by Janko MivÅ¡ek Oct. 21, 2011

Hi guys I have nonstartable Pharo 1.3 image, is there any way to get it started? This image was running all the time, being on the net directly (Aida based web development image) and snapshoting every hour. The problem happens at such snapshot, raising Not enough space for external objects/too many semaphores error and block. After I killed it, snapshoted image is not startable anymore, more exactly: it starts in blank window and stays unresponsive. Is this too many semaphores error related to too many open sockets problem we discussed not to long ago? Any help greatly appreciated. Not to mention finding a bug and removing it forever, because Pharo should become stable as a rock, as VW for instance is :) Best regards Janko PharoDebug.log: THERE_BE_DRAGONS_HERE Error: Not enough space for external objects, set a larger size at startup! 4 October 2011 4:00:01 am VM: unix - i686 - linux-gnu - Croquet Closure Cog VM [CoInterpreter VMMaker-oscog.35] Image: Pharo1.3 [Latest update: #13299] SmalltalkImage(Object)>>error: Receiver: Smalltalk Arguments and temporary variables: aString: 'Not enough space for external objects, set a larger size at startup!'...etc...

[Pharo-project] When will Fuel file format stabilize?
by Janko MivÅ¡ek Oct. 21, 2011

Oct. 21, 2011

Hi guys, We are starting to use Fuel to exchange data daily, but without exactly the same version of Fuel loaded, exported data is just too frequently not importable anymore. And exception report is meaningless, you can only guess that Fuel version is to blame. So, it is more that a time to: - stabilize and freeze the file format - put a version info into a file and check it while importing - meaningful error reporting in such cases This is IMHO more than necessary for Fuel to become a production ready serializer and I'd say Fuel is now "old enough" to become such :) Best regards Janko -- Janko MivÅ¡ek Svetovalec za informatiko Eranova d.o.o.
