Reddit example

Thanks for the pointers. I've got it working in Pharo 4 but had to change this method as I was getting a database session connection error. It appears to be losing the Glorp session, so I changed this class method thus: RedditDatabaseResource login>> "^ DefaultLogin ifNil: [ DefaultLogin := self createLogin ]" ^ DefaultLogin := self createLogin.

Detecting image (pharo process) hang?
by David June 3, 2015

June 3, 2015

I am making a little watchdog (in C++) for spawning forked pharo image processes and detecting when they crash (for ex, memory exhausted and/or killed) so it can restart the image. It works, but for now I have only 1 remaining thing: How can I detect from outside, when pharo process is hanged and not responsive? I am thinking something like sending SIGUSR1 (which should output a backtrace) and if nothing is produced, then kill the pid. The problem is that when I do so, then image is completelly unresponsive (all is blank and not responsive to any event, click and so). Is there anything better?

RWView signalUpdate
by Lusa Nicolas June 3, 2015

June 3, 2015

Hi, I noticed that with the recent changes that you made the view isn't updating anymore so I would like to update it by myself. I saw that in RWView there is the method called signalUpdate which is supposed to update the view but when I call it actually nothing happens. The situation that I have when I use it: - I have some objects in gray color displayed in my view. - I change the color and update the element. At this point the view doesn't update automatically so they stay gray even though I changed the color - I call signalUpdate on my view but nothing refreshes, the objects stay gray. At first I thought the problem was that the instance variable signalUpdateCallback was not initialised since in the initialisation is set to be nothing. But then I noticed it is actually initialised in RWViewWindow so that should be fine. I also have to say that my focus is not on the window that displays my objects but on another window in the same pharo image (just beside the window that contains the objects). Might that be the problem? Even though I have this situation I really would like to update the view even though the focus is not on that window. Any idea on how to make it work? Thanks Nicolas. P.S. any news on the possibility to distinguish different buttons interactions (i.e. distinguish left from right click of the mouse)?

PUngLite can't query large database
by Gareth Cox June 3, 2015

June 3, 2015

Hi I've managed to create a large database, with PUnqLite, that is 562.1MB. I can't seem to query it though. I've set fetchBufferSize: (1024*1024*1023). I've set SmalltalkImage current vm extraVMMemory: (1024*1024*1023). I've played around in the info.plist setting the SqueakMaxHeapSize to ridiculous things. But I keep getting either out of memory or PqFetchError (probably because it can't fit the whole stream into the image?). This is why I was asking about the JX9 query and running a query like that to only return to the image with results I want. Any suggestions on how I can handle this? Info.plist: > <key>SqueakMaxHeapSize</key> > <integer>1073741824</integer> Pharo: > Image > ----- > *****/Pharo4.0.image > Pharo4.0 > Latest update: #40611 > Unnamed > > Operating System/Hardware > ------------------------- > Mac OS 1093 intel Kind Regards -- Gareth Cox IT Manager/Developer Inspired Org (PTY) Ltd

sorting repositories in monticello browser
by Peter UhnÃ¡k June 2, 2015

June 2, 2015

Hi, is it possible to sort repositories in monticello browser? When I have many (20+) packages it is quite hard to find any one. :( Or perhaps even swap repository names around... so instead of http://smalltalkhub.com/#!/~Moose/PetitParser/ github://Uko/QualityAssistant:v0.4.1 gitfiletree:///home/.../me/my-project master there would be something like Moose/PetitParser (SmalltalkHub) Uko/QualityAssistant [v0.4.1] (GitHub) me/my-project [master] (GitFileTree) and of course sorted by alphabet. Thanks, Peter

Re: [Pharo-users] Slot questions
by Paul Davidowitz June 2, 2015

June 2, 2015

To Camillo Bruni: I'm not using any slot image (I only looked over the paper). According to the Pharo book, 'pvt' should be implemented in the mainstream image. To Marcus Denker: There are actually several methods in the image with the 'pvt' prefix. Please update the doc (Pharo book) to remove talking about 'pvt'. It would have saved me a little headache :)
