[Pharo-project] old windows in image not responding
by Ben Coman Oct. 22, 2011

Oct. 22, 2011

I have just opened a Pharo image on Windows 7 that I haven't touched in months. This was originally derived from the Pharo.1.2.1.OneCick, and the TitleBar > 'Display Version Information' indicates "About Pharo on Win32 - Pharo4.1.1 from Mar 3 2011". I assume the image was left it in good working order, but now the 16 open windows (including a pinned World Menu) are not responding to any mouse click. Clicking over them brings up a fresh World Menu as if I just clicked on the background. From this fresh World Menu, I can open a properly functioning Workspace and Browser. It seems like a snapshot "old" windows has become the background image, except that from the window-bar and bottom of screen going "Windows > Collapse All Windows" does collapse the "old" windows - and "Windows > Expand All Windows" restores them, but they still cannot be selected. One of the "old" windows is a dialog box "Question: Save changes before quitting Yes/No/Cancel" which is the single "old" window I can select. Choosing Yes or No closes the image and choosing Cancel keeps me in the image, but still with none of the "old" windows selectable. I naively speculate that I was closing the image and walked away while "save changes" dialog was open, and in the meantime the power dropped out to the machine. It would be nice to regain access to some code snippets in the "old" Workspace, but just closing all the "old" of them would be okay. Your thoughts on possible causes and alternatives to fix would be appreciated. cheers, Ben

[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

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...
