[Pharo-project] NativeBoost question
by GÃ¶ran Krampe Jan. 23, 2013

Jan. 23, 2013

Hey! I have a struct something like this: struct { const char * attribute; int size; int datatype; } ...and I am trying something like this to match an NBExternalStructure: fieldsDesc ^#( String attribute; int size; int datatype; ) ...or even this: ^#( NBExternalString attribute; int size; int datatype; ) All these give me some DNU (nil) for #asAJOperand when emitting code. The only one that works is when I use NBExternalAddress as can be seen in action in NBTestStructure2. Is this by design or am I simply an early adopter and support for String etc isn't there yet? regards, GÃ¶ran

Re: [Pharo-project] [Pharo-users] Pharo 2.0 - System Error Handling Failed
by Sven Van Caekenberghe Jan. 23, 2013

Jan. 23, 2013

I really think that for the process of polishing 2.0 from beta to release we need a new label for issues. Bugs like the one below are really important, they might be silly or easy to fix, but they leave a bad impression. We want as many people as possible to help, but UX failures like this will scare away many users, most won't be as helpful as Andy to even report the issue. We as developers know that 2.0 is OK because we use it every day, but occasional users who just try 2.0 for the first time can't know that. So not HorribleErrorBlockingEverything but maybe HorribleUXQualityBugScaringAwayNormalPeople as label ?

Re: [Pharo-project] iCal port to Magritte3
by Yanni Chiu Jan. 23, 2013

Jan. 23, 2013

Hmmm. It seems the ConfigurationOf is expecting GemStone and Squeak, not Pharo. Yikes, the differences in Date, Time, DateAndTime, timezones, etc. across dialects and versions is a *challenge*. I probably don't need Magritte3. I just want to create ical files. [Aside.

[Pharo-project] User Interrupt Broken?!
by Sean P. DeNigris Jan. 23, 2013

Jan. 23, 2013

Has anyone else noticed this? Open a fresh 2.0482 latest and hit Cmd-. a bunch of times. If the debugger opens on the first, close it and keep pressing the shortcut. Most presses seem to do nothing. -- View this message in context: http://forum.world.st/User-Interrupt-Broken-tp4664619.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Object>>#name
by Sven Van Caekenberghe Jan. 22, 2013

Jan. 22, 2013

Hi, Many people have hit the fact that Object implements #name, which then seems to conflict with some other class where one would really like to use name as an instance variable and thus accessor. Turns out that it seems that Object>>#name is actually not used (anymore). I just put a halt in it and tried a couple of tools and everything seems to work just fine. The comment talks about Inspector use, but there is #defaultLabelForInspector for that. It is a small thing, but it confuses everybody for no good reason, Any comments ?

Hi I'm trying the Temporaries read before written and I have the impression that I found a bug in the RBReadBeforeWrittenTester class because it flags connections (but connections is not a temp but an instance variable). Did anybody experience the same? Stef listenLoop "Private! This loop is run in a separate process. It will establish up to maxQueueLength connections on the given port." "Details: When out of sockets or queue is full, retry more frequently, since a socket may become available, space may open in the queue, or a previously queued connection may be aborted by the client, making it available for a fresh connection." "Note: If the machine is disconnected from the network while the server is running, the currently waiting socket will go from 'isWaitingForConnection' to 'unconnected', and attempts to create new sockets will fail. When this happens, delete the broken socket and keep trying to create a socket in case the network connection is re-established. Connecting and disconnecting was tested under PPP on Mac system 8.1. It is not if this will work on other platforms. Fixed to not accept the connection if the queue is full (gvc)." | newConnection | socket := Socket newTCP. "We'll accept four simultanous connections at the same time" socket listenOn: portNumber backlogSize: 4. "If the listener is not valid then the we cannot use the BSD style accept() mechanism." socket isValid ifFalse: [^self oldStyleListenLoop]. [true] whileTrue: [ socket isValid ifFalse: [ "socket has stopped listening for some reason" socket destroy. (Delay forMilliseconds: 10) wait. ^self listenLoop ]. [newConnection := socket waitForAcceptFor: 10] on: ConnectionTimedOut do: [:ex | newConnection := nil]. (newConnection notNil and: [newConnection isConnected]) ifTrue: [(accessSema critical: [connections size < maxQueueLength]) ^^^^^^^^^^ ifFalse: [newConnection close. newConnection := nil]] ifFalse: [newConnection := nil].

[Pharo-project] Fonts in Pharo By Example
by Sean P. DeNigris Jan. 22, 2013

Jan. 22, 2013

It would be great to have a section in PBE2 about fonts. I find them very confusing - TrueType, FreeType, Logical, etc. Understanding how they're handled in Pharo requires background knowledge, and an overview and a few specific examples could really do some good.
