Re: [Pharo-project] How to encrypt a password?
by Paul DeBruicker Nov. 22, 2013

Nov. 22, 2013

Hi Mariano, I've made a FFI library on Squeaksource that works on Linux. http://www.squeaksource.com/Cryptography/PasswordHashingFFI-PaulDeBruicker.… You need to install the 32 bit versions of libcrypt and libxcrypt if you're using a 64 bit linux os. Using crypt can hash passwords using MD5, DES, SHA256, SHA512. Using libxcrypt can hash passwords using bcrypt. If its for a new installation use bcrypt or SHA512 to hash the passwords. bcrypt is better because its slower, and allegedly future proof. to get a hashed password use BCryptLinuxFFI bcrypt:'mypassword' to check it against a stored hash use: BCryptLinuxFFI check:'mypassword' against: storedHash

[Pharo-project] TextAttribute, TextAction and TextDoIt or TextURL: not working
by phil＠highoctane.be Nov. 6, 2013

Nov. 6, 2013

I've been investigating with text. I found things that do work like: ((Text withAll: 'foo') , (Text string: '*' attribute: (TextAnchor new anchoredMorph: EllipseMorph new)) , (Text withAll: 'bar')) asMorph openInWorld. ((Text withAll: 'foo') , (Text string: '*' attribute: (TextAnchor new anchoredMorph: ThemeIcons confirmIcon)) , (Text withAll: 'bar')) asMorph openInWorld. But doing: ((Text withAll: 'foo') , (Text string: 'some link' attribute: (TextURL new url:'http://philippeback.eu')) , (Text withAll: 'bar')) asMorph openInWorld. gives me a nice purple 'some link' bit but clicking on it fails with MessageNotUnderstood: TextURL>>actOnClick:for:in:editor: Damn! Ideas on how to tackle this? TIA Philippe Back

[Pharo-project] Render images - Porting from Cincom VW to Pharo
by Emilia Oct. 15, 2013

Oct. 15, 2013

Hello! I'm porting code from Cincom Smalltalk to Pharo. It's a web application so I've got several WAComponent instances and one component which inherits from WAFileLibrary that renders images. In the original code ( the one that runned in VW) i had the following instance method in the component that inherits from WAFileLibrary: logoJpg ^ByteArray asPackagedString: '?=#?8@@PR$YIQ @A@ D@X@A @@C?8P))QW!)Y @@RT$*@@ @@@@G@AHA@0@......etc etc' But now when i run it in Pharo the debbugger doesn't recognize #asPackagedString: message. Does anyone know which method should I use in order to render that image? Thanks in advance! Mercy beaucoup! Emilia

[Pharo-project] Issue 3015: When a test is restarted in the debugger, #tearDown and #setUp and not send
by Hernan Wilkinson Aug. 28, 2013

Aug. 28, 2013

Hi, I added a new issue (that I think it could be see as an improvement, not an issue) that is related to debugging a test case written with SUnit. The problem is that when you restart a test in the debugger (either by pressing the restart button or compiling the method again) the changes made by the test to the objects initialized in the #setUp are not rollbacked. This change sends the messages #tearDown and #setUp to the test when restarting it, therefore letting the test in the same state as when it was run in the first place. I uploaded the solution to this issue (or improvement) to pharo inbox under SLICE-Issue-3015-RestartingATestFromTheDebuggerSendsTearDownAndSetUp-HernanWilkinson.2 I hope you like it!

[Pharo-project] Pharo VM - More Memory on Mac
by Dennis Schenk July 24, 2013

July 24, 2013

Hi all, I know there is already a related question about the Pharo VM on Windows. But as it seems, it is kind of hard to get over 512MB there, so I'm trying to do stuff on Mac. When using Cog I was able to use Cog.app --args -memory 2000m to allow Cog to run with 2GB of memory. Which then works fine with the same data I want to work with in Pharo. But I would like to use Pharo 2.0 and the Pharo VM, instead of Pharo 1.4 and the Cog VM. How would I achieve giving the Pharo VM more memory on Mac? If I am not mistaken, I currently only have 1GB, which is not enough, my image crashed when dealing with large data. Also, is there a way to check how much memory the VM has available in the workspace? I tried some arguments, but could only find out if they had any effect by getting to a crash after letting it do some work. Cheers, Dennis

[Pharo-project] Understanding NBOpenGL
by kilon July 4, 2013

July 4, 2013

Ok so I tried to learn Opengl ES 2 (and opengl 4) during my eastern vacations because I realised that I dont really need Athens or vector graphics for my GUI , since I will be dealing mostly with 3d graphics anyway. (My project "ephestos" will be an effort of creating a 3d app for pharo, see also "blender") So when I tried to run the demos i get an error with NBMacGLContextDriver>>supportsCurrentPlatform "obviously, for Mac intel-32 only :)" ^ NativeBoost platformId = NativeBoostConstants mac32PlaformId My mac is "obviously" not 32-bit but 64 bit, but I dont know if that matters since pharo is only 32 bit anyway. The bug is also obvious it should be mac32PlatformId and not mac32PlaformId. I correct and proceed and gives me a new error this time in NBMacGlApi>>glApiCall: fnSpec index: fnIndex attributes: attributes context: contextToRetry ^[ (NBCallFailureHandler for: contextToRetry) retryWith: [ :targetClass :targetMethod | (NBFFICallout targetClass: targetClass targetMethod: targetMethod fnSpec: fnSpec) stdcall; generate: [ :gen | self emitCall: fnIndex generator: gen ] ] ] on: NBNativeCodeError do: [:err :handler | err errorCode = ErrorFnNotAvailable ifTrue: [ "Native code is installed, but function pointer not loaded yet. Try to load function and retry the call" (self tryGetFunctionPointer: (self class glFunctions at: fnIndex)) ifFalse: [ ^ err pass ]. ^ handler retrySend ]. err pass ] The problem here that NBCallFailureHandler is nowhere to be found. At first I though my NB was lagging behind in version so I download from smalltalk Hub and did ConfigurationOfNativeboost loadStable. it updated without errors but still that class is nowhere to be found. So my question is this, does it really worth it to struggle with NBOpengl or will it better to learn how Nativeboost works and use Opengl myself ? -- View this message in context: http://forum.world.st/Understanding-NBOpenGL-tp4686514.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

Zinc problem with PUT requests
by Damien Cassou June 18, 2013

June 18, 2013

It looks like Zinc has a problem handling PUT requests (at least ZnZincServerAdaptor). If I replace ZnZincServerAdaptor by WAKom, then things work fine. To reproduce: Setting up the Server 1- Download a SmalltalkHub image (https://ci.inria.fr/pharo-contribution/job/SmalltalkHub/) 2- Install mongodb on your computer (for Debian: apt-get install mongodb) 3- Launch the SmalltalkHub image 4- Evaluate: ZnZincServerAdaptor startOn: 8080 5- Visit http://localhost:8080/tools/hub, create an account and a project Setting up the Client 6- In a different image, start monticello 7- add the repository of your new project to Monticello (something like http://localhost:8080/mc/YourUser/YourProject/main) don't forget the username and password 8- copy an existing package of your cache to the new repository You will get an error in the client: a ZnStringEntity(text/plain 512B file is too short) If you install Seaside-Adaptors-Kommanche and use WAKom, things will work just fine. You can configure Seaside to open a server-side error: just setup the WAExceptionFilter to WADebugErrorHandler in http://localhost:8080/config/mc -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."

Auto-Subscribe in Fogbugz

I was wondering if it could be set up like google was where you were automatically subscribed to issues you created... it can (and more)! 'My Settings'->Subscribe->'Add New Subscription'->'ANY ITEM I CREATE' You can also subscribe to a particular project's cases (e.g. Opal), wiki edits, discussions, or 'ANY ITEM I EDIT' ----- Cheers, Sean -- View this message in context: http://forum.world.st/Auto-Subscribe-in-Fogbugz-tp4690614.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
