Re: [Pharo-project] [Seaside] Problem with announcements in Seaside when using Pharo 1.3
by Tudor Girba July 17, 2011

July 17, 2011

The issue described by Andrei seems to happen only in the context of an announcement. The on:fork: fixes proposed by Igor and Stef plus overriding DynamicVariable>>alwaysResuming, seem to solve the problem. Btw, how can we get the new implementation of on:fork:? It would be cool to get someone else to test them.

[Pharo-project] image freezes when setting time "back"
by Philippe Marschall July 17, 2011

July 17, 2011

Hi I have had the following experience. I'm running Pharo 1.3 on a Linux box where the time is set on start up using ntp. The hardware clock is set to the local time (because I'm dual booting). When there is no network connection during booting the system the clock is two hours "ahead" until I get network connection and set the time using ntp. When a Pharo image is running during this the UI freezes and doesn't react anymore. Does anybody else observe this? Is this a known limitation? Sorry if this message got sent twice. I had some trouble with the mailing list. Cheers Philippe

Is this class in dedicated package? I did not find it in PharoNonCore. If so I will revive it and put it there. Hilaire -- Education 0.2 -- http://blog.ofset.org/hilaire

[Pharo-project] funky ::

Hi guys I found that henrik succeeded to compile and get in MC you just need to define unprotectedExternalObjects:: foo self and after you can easily define clearExternalObjects "Clear the array of objects that have been registered for use in non-Smalltalk code." ProtectTable critical: [self unprotectedExternalObjects:: Array new]. I'm not convinced that it is good :) stef

[Pharo-project] SerialPort>>openPort:
by Schwab,Wilhelm K July 17, 2011

July 17, 2011

I am starting to build a 1.3 image, and taking the usual look around for things that would get lost. SerialPort>>openPort: appears to address named ports, but it looks like it will miss failures. What I did for 1.1 is capture the result of the primitives and raise an error if it is nil. Any interest? As an aside, does anyone know the state of serial ports on Linux? With Cog? I have been having good luck with native ports using Andreas' Windows VM. I have not done as well on my Linux laptop, but I can't tell whether that is related to Linux, the Linux VM, or (my lead theory) USB-serial converters. I need to get Ubuntu on a box with native ports and put it where I can stress test serial I/O; it has been a elusive combination, but I will get there. Bill

[Pharo-project] Bug in 1.3 - in Shout??
by Schwab,Wilhelm K July 16, 2011

July 16, 2011

Hello all, The recent 1.3 builds get upset with code such as anobject from:-1 to:3. Specifically, the problem is the "leading" negative sign. I *think* the problem is limited to Shout's highlighting of it; the compiler appears to handle it. Bill

[Pharo-project] Hanging connects, exhausted resources, memory leaks, bocked everything ... Unusable!
by Guido Stepken July 15, 2011

July 15, 2011

I am doing server tuning, building up fast server systems for a very long time now. Yesterday i installed 1.2.1, expecting to see a far more matured Pharo Smalltalk, stable, pretty nice new features. I opened up the Memory Grapher, hmmm.... works fine, watching memory pumping. A bit strange, seeing a Pharo consuming and freeing megabytes of memory space without any load. But ok! Then i opened up TestSuites, marked some tests, let them run. Ups! Desktop hanging. I expected to have with Pharo a well done, stable multitasking environment, but Pharo hangs everywhere, is leaking lots of memory, is keeping up connections, wasting resources unneccessarily, having problems with internal race conditions on semaphores, mutexes, feels same like "Big Kernel Lock", but even without MultiProcessing. The Pharo Team IMHO is very much missing important knowledge about modern Operating System Design, what Pharo Smalltalk OS is in fact, without being able to fulfill the minimum standards i expect from a usable Smalltalk OS. As system operator or enterprise i cannot offer such a system, that has to be restarted twenty times a day, due to hangs, memory leaks, sucking connection handles, ..., whatever! tnx for your understanding! regards, Guido Stepken

Thanks Danie. I don't have time to take a look right now, but maybe someone can. Anyway, you may know AutomaticMethodCategorizer much better than us. So you can just go ahead and commit and update ConfifugrationOfAutomaticMethodCategorizer On Wed, Jul 13, 2011 at 5:27 PM, Danie Roux <danie(a)danieroux.com> wrote: > Hi Mariano, > > We need the capability to set custom rules on > AutomaticMethodCategorizer.
