Personally, I'd rather have createContext: taking a crossplatform pixel/buffer format as argument, the platform context transcribe that into the native object needed as parameter for context creation, and some sort of way to check if the context created actually matched your specification. Makes the whole "Your context was invalid for those operations" class of errors a lot more transparent, which I've found to be the source of trouble multiple times at least. Cheers, Henry

Hi Igor, i have a question regarding the design of NBOpenGL. Why does the following offscreen method, deals with windows? NBOffscreenDisplay >>createOpenGLContext ctx := NBHostWindowContext createSpecificForPlatform. ctx createWindow: extent. ctx createContext: ctx defaultPixelFormat. I'm trying to include in the framework, support for MacOSX, starting with offscreen drawables support using CGL, therefore i would like to modify it to: NBOffscreenDisplay >>createOpenGLContext ctx := NBDisplayContext createSpecificForPlatform. ctx createContext: ctx defaultPixelFormat. NBGLDisplay NBDisplayContext NBOffscreenDisplay NBWindowedDisplay NBWinContext NBUnixContext NBMacOSXContext What do you think? Fernando

Re: [Pharo-project] Help: Zodiac secure server.

I was able to successfully make a server copying most of the server part from Zinc Http server. Then, I tried replacing the SocketStream with your ZnSecureSocketStream but that didnât workâ¦ I havenât read much on SSL yet so I assumed whatever was sent from the secure stream of the client would be decrypted on the server using ZnSecureSocketStream â like a toggle mostly but I guess I am wrong. Iâd appreciate it if you could give me some pointers or if you had a sample of such a secure server implementation. > > Thank you, > Prasad Thanks a lot for your interest in Zn+Zdc, this is a good area to work on. I haven't done this myself yet, for a couple of reasons: - lack of time - debugging Zdc was higher priority - client side was/is higher priority That being said, it would be nice if you could do a proof of concept. To make this work you have to do wrap a ZdcSecureSocketStream on: the socket that you get back from #waitForAcceptFor: The place to do this is in ZnSingleThreadedServer>>#socketStreamOn: It would be best to do this in a subclass from either ZnSingleThreadedServer or ZnMultiThreadedServer Then you have to set the server certificate on the stream by getting the #sslSession from the ZdcSecureSocketStream that you just created and calling #certificateName: (this won't work on Mac OS X due to missing functionality in the plugin). Finally you should do a #accept on the ZdcSecureSocketStream, if that works, the server should work transparently with the secure stream as if it is a regular one. Apart from debugging, there is no reason this should not work ;-) Good luck and please let me know how it goes! Regards, Sven

[Pharo-project] A possible bug in GZip streams
by Martin Dias Dec. 9, 2011

Dec. 9, 2011

Hi, I get a SubscriptOutOfBounds error when I evaluate: | aStream zipStream | aStream := ByteArray new writeStream binary. zipStream := GZipWriteStream on: aStream. zipStream nextStringPut: ''. zipStream nextStringPut: ''. zipStream close. aStream close. aStream := aStream contents readStream binary. zipStream := GZipReadStream on: aStream. zipStream nextString. zipStream nextString. zipStream close. aStream close. The error doesn't happen when I put just one string (instead of two). Do you see something wrong in the code? Should I report a bug? Thanks, MartÃn

[Pharo-project] ZdcSecurePOP3Client and ZdcSecureSMTPClient
by Sven Van Caekenberghe Dec. 8, 2011

Dec. 8, 2011

This week I found some time to finish two small examples, ZdcSecurePOP3Client and ZdcSecureSMTPClient. These are subclasses from the POP3Client and SMTPClient already present, but open a ZdcSecureSocketStream to the POP3/SMTP server and connect it at the SSL level. This means you can now receive and/or send email securely over SSL, to GMail for example: "Retrieve (but not delete) your last 5 messages" ZdcSecurePOP3Client retrieveMessagesFromGMailAccount: '<your-name>@gmail.com' password: '<your-password>' limit: 5. (Note that you have to enable POP3 access in your GMail account) "Send a message" | mailMessage | mailMessage := MailMessage empty. mailMessage setField: 'subject' toString: 'ZdcSecureSMTPClient Test'. mailMessage body: (MIMEDocument contentType: 'text/plain' content: 'This is test from Pharo Smalltalk'). ZdcSecureSMTPClient sendUsingGMailAccount: '<your-name>@gmail.com' password: '<your-password>' to: '<email-address>' message: mailMessage The code is in the 'Zodiac-Extra' package in the http://www.squeaksource.com/Zodiac repository. Of course, you also have to install Zodiac and a plugin, see http://zdc.stfx.eu/ for more details. Sven

>From the Collaboractive book: a tool to inspect live events If you want to inspect events generated by an announcer without a priori knowledge about the kind and frequency of events, you can always open a spy on an announcer to track its events. announcer open or AnnouncementSpy openOn: announcer This opens a window which displays the sequence of events emitted by the announcer (after the spy has been launched). You can open/inspect each event individually using the contextual menu. you can also clear the list view. Try it on World announcer open (in Pharo 1.1 or later), then add and close windows to see events generated. -- View this message in context: http://forum.world.st/COTDC-93-AnnouncementSpy-tp4173986p4174271.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.
