[Pharo-project] UDP Broadcast Problems on Mac
by Philippe Marschall Sept. 5, 2010

Sept. 5, 2010

Hi I have some code that listens to UDP broadcasts. It works on Linux but on the Mac it never receives anything (the first element in the array is zero *sigh*). This is with Pharo 1.1 and Cog but also happens on Pharo 1.0 without Cog. The code looks more or less like this: socket := Socket newUDP. socket setPort: 23364. buffer := String new: 65507. [ socket isValid ] whileTrue: [ | datagramm | datagramm := socket receiveUDPDataInto: buffer ] The broadcast happens to 224.0.1.105 on port 23364, tcpdump picks up the packes on lo0. I could provide tcpdump output or steps to set up sever that sends the broadcasts. Cheers Philippe

Re: [Pharo-project] [Moose-dev] glamorous theme :)

The contrast between the gray text and the blue background is too low. It could be improved by using outline style. - The gradient is blue is much stronger than that in black. I would say the black needs more lights. The buttons contrast too much with the light gray background. - The disabled checkbox misses a line at the top - Borders of button, checkbox and radiobutton should look similarly sharp. Now the button looks sharp, while the others look blurry. The same goes for drop lists, normal lists and text editor. - Vertical spacing between the radiobuttons is inconsistent. - Text Entry looks like it has more height when disabled. This is due to the top gradient of the non-disabled one. - Disabled slider handle is too dark. - Backgound color for Text Entry, Slider, List (s) and Text editor should be the same for disabled state. The same goes for disabled text foreground color. Why has disabled drop list a different text color than a disabled text entry? - Lists should have the same corner as text entry. - Drop list button has the V a-symmetrical. - Difference between normal list and disabled list is too small. - The border between scroll bar buttons and light gray background is not enough pronounced.

[Pharo-project] Key bindings bug in Windows
by Stanislav Paskalev Sept. 5, 2010

Sept. 5, 2010

Hi, using the 1.1 image, whenever I type shift+"Ð¾" (Cyrillic/Bulgarian letter O) on Windows, instead creating a character, it looks like it's recognized as shift+upper arrow - it moves a line above selecting text. (it works fine when I type it in say notepad, also works ok when pasted into Pharo) If I remember correctly - this didn't happen when I was using Pharo under debian, so it's probably a platform issue. Regards, Stanislav Paskalev

[Pharo-project] Is there a way to limit taskbar
by StÃ©phane Ducasse Sept. 5, 2010

Sept. 5, 2010

Hi guys in one of our server we got that! - two reactions - we should limit the number of taskbar elements - would be good to have also a real logger (if this is not the case here) instead of transcript to report structured log I will have a look at SimpleLog of goran Stef Begin forwarded message: > From: Damien Pollet <damien.pollet(a)inria.fr> > Date: September 4, 2010 8:00:33 PM GMT+02:00 > To: notre liste <lsehub-staff(a)lists.gforge.inria.fr> > Subject: Re: [Lsehub-staff] apparently http://rmod.lille.inria.fr/ does not answer... anymore. > Reply-To: notre liste <lsehub-staff(a)lists.gforge.inria.fr> > > VNC works, but here's what it looks like.

[Pharo-project] Memory problems on Windows
by Jimmie Houchin Sept. 4, 2010

Sept. 4, 2010

Hello, I am developing an application which processes and generates a large amount of data. In a recent attempt I encountered an Space is Low error. This is occurring in a Pharo 1.1 image using the latest Pharo and Cog VMs. I am opening the vm with the -memory: 1000 parameter. The below code I have applied the from the Squeak list from the 100 Million Objects thread. But the problem occurs at about 500mb of ram on a computer with 3 (or 6) gb of ram, with only 65% of physical ram in use. The os is Vista. Any help in using more memory, as much as necessary for the app, would be greatly appreciated. initializeMemorySettings "Initialize the memory and GC settings to be more in line with QF requirements" "The following settings affect the rate incremental GCs and tenuring" "Limit incremental GC activity to run every 40k allocations" SmalltalkImage current vmParameterAt: 5 put: 40000. "allocations between GCs (default: 4000)" "Limit tenuring threshold to only tenure w/ > 10k survivors" SmalltalkImage current vmParameterAt: 6 put: 10000. "tenuring threshold (default: 2000)" "These settings affect overall memory usage" "Only give memory back to the OS when we have more than 16MB free" SmalltalkImage current vmParameterAt: 24 put: 16*1024*1024. "default 8MB" "Try to keep 8MB headroom at all times" SmalltalkImage current vmParameterAt: 25 put: 8*1024*1024. "default 4MB" "These settings describe what to do when we're close to running out of free space" "Tell the VM that we'd rather grow than spinning in tight GC loops" SmalltalkImage current gcBiasToGrow: true. "default: false" "Tell the VM to do a fullGC for good measure if the above growth exceeded 16MB" SmalltalkImage current gcBiasToGrowLimit: 16*1024*1024. "default: 0" Thanks, Jimmie Houchin

[Pharo-project] Loop while debugging #expectedFailures
by Mariano Martinez Peck Sept. 4, 2010

Sept. 4, 2010

Hi. There is a loop when trying to debug #expectedFailures. To reproduce, just put a "self halt" at the beggining of a #expectedFailures method and then run of the tests of that class. The problem is that when you put the self halt, in an #expectedFailures, it brings a debugger, of course. But the debuggers needs to send the printOn to all the stuff in the context. TestResult implements printOn: in this way: printOn: aStream aStream nextPutAll: self runCount printString; nextPutAll: ' run, '; nextPutAll: self expectedPassCount printString; nextPutAll: ' passes, '; nextPutAll: self expectedDefectCount printString; nextPutAll:' expected failures, '; nextPutAll: self unexpectedFailureCount printString; nextPutAll: ' failures, '; nextPutAll: self unexpectedErrorCount printString; nextPutAll:' errors, '; nextPutAll: self unexpectedPassCount printString; nextPutAll:' unexpected passes'. which...as you can see sends the message #expectedPassCount which at the ends...sends #expectedFailure.....sooo....loop :) I am still thinking which could be the better solution. I will try to come up with it later. Cheers Mariano

I yearn for package comments, especially when hunting for a starting point in a new package. What say you? Sean p.s.
