You seem to be using an old VM. /home/jpfersich/pharo64-6.0/pharo-vm/lib/pharo/5.0-201704181925/pharo Pharo VM version: 5.0-201704181925 Can you try with one of these... http://pharo.org/download i.e. Pharo6.0-linux.zip/pharo6.0/bin/lib/pharo/5.0-201705310241/pharo So actually yours is not so out of date that first glance at the "5.0" in your path implies. @Esteban, can this packaging be corrected? cheers -ben On Fri, Jun 9, 2017 at 12:21 PM, john pfersich <jpfersich(a)gmail.com> wrote: > I got a seg fault when I tried to execute some OSSubProcess code in Pharo > 6.0. > > Namely, > > | process | > process := OSSUnixSubprocess new > command: '/bin/cat'; > redirectStdin; > redirectStdout; > run. > process stdinStream > nextPutAll: 'we are testing!'; > nextPutAll: 'we again!'; > close. > process waitForExit. > process stdoutStream upToEndOfFile inspect. > process closeAndCleanStreams. > > Attached is the crash.dmp file >

Hi John, Was this using 64bits flavor ? If true, can you try with 32 and let me know? I ask because I know OSSubprocess doesn't work on 64 bits yet, but to fix this I need some pull requets merged in the VM...

Re: [Pharo-users] [Moose-dev] dynamic interaction with Mondriam

Hi! Simply using Mondrian is complicated to do this (Mondrian is not made to produce interactive & dynamic visualizations). Instead, it would be great that you could try DataStudio, which is exactly designed for this kind of situations. You can load DataStudio by using a dedicated plugin: You can try some examples: | c | c := CAArtwork new. c doAction: (CAAddElementAction new argument: (1 to: 7)). c doAction: (CAAddEdgeAction new argument: [ :e | e + 1 ]). c doAction: (CASwitchLabelAction new). c doAction: (CAShapeSizeAction new argument: 30). c doAction: (CAGridLayoutAction new). ^ c view Here another example: | c | c := CAArtwork new. c doAction: (CAAddElementAction new argument: (Collection withAllSubclasses)). c doAction: (CAAddEdgeAction new argument: #subclasses). c doAction: (CAShapeHeightAction new argument: [ :cls | cls numberOfMethods max: 5 ]). c doAction: (CAShapeWidthAction new argument: [ :cls | cls numberOfVariables * 5 max: 5 ]). c doAction: (CAShapeNormalizedColorAction new argument: [ :cls | cls numberOfLinesOfCode ]). c doAction: (CATreeLayoutAction new). c doAction: (CAAddGroupAction new argument: [ :cls | '*Array*' match: cls name ]). c doAction: (CASwitchLabelAction new). ^ c view You will end-up with something like: Let me know how it goes...

Re: [Pharo-users] Teapot: Managing authentication by a third party (Fossil)

by Attila Magyar

IMO it depends on how the API works. Most REST APIs are stateless and the authentication token or api key is sent in each request, there is no login/logout operation. In this case you can setup a before filter and check the authentication token in the filter. If you use normal form based login then using http sessions is the way to go. You can check the session attribute in a before filter similarly, and redirect the user to the login page if there is no session info. Teapot on before: '/secure/*' -> [:req | req session attributeAt: #user ifAbsent: [req abort: (TeaResponse redirect location: '/loginpage')]]; GET: '/loginpage' -> ...show login form... GET: '/secure' -> 'protected'; start. You should clean the session when the user logs out manually. As far as I know ZnServer automatically cleans up inactive sessions after a while, so there is no need to worry about cleanup. -- View this message in context: http://forum.world.st/Teapot-Managing-authentication-by-a-third-party-Fossi… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Its a great offer, but I'm not ready right now to try it, and in a few months I'll have forgotten. Or better, the Association should post here a monthly promotion flyer/newletter that lists deals like this. cheers -ben
