[Pharo-project] Pharo Wishlist (was Native Windows in Pharo)
by Sean P. DeNigris Dec. 6, 2010

Dec. 6, 2010

There was a ( hijacked ;-) ) thread on the user list about a feature wishlist. Although I think the "Benevolent Dictator" model is better suited for this stage of Pharo's evolution, it would be cool for the dictators (since they are benevolent and the opin-ers will not "disappear") to see what the community is passionate about. The reference was to the http://uservoice.com/ online app, which I've enjoyed using for PersonalBrain (http://www.thebrain.com/) Sean See relevant quotes below from http://forum.world.st/Native-Windows-in-Pharo-td3071794.html: Andres Fortier-2 wrote: > > Ok, I see.

[Pharo-project] Issue 3383 in pharo: [FIX] make String >> #subStrings: do less allocation
by pharo＠googlecode.com Dec. 6, 2010

Dec. 6, 2010

Status: Accepted Owner: philippe.marschall Labels: Type-Patch Difficulty-Easy Importance-Low New issue 3383 by philippe.marschall: [FIX] make String >> #subStrings: do less allocation http://code.google.com/p/pharo/issues/detail?id=3383 String >> #subStrings: does a lot of allocation. It allocates a new string for almost every character. So if you do something like '/alongUrl/withaPathElement/andSomethingMore' subStrings: '/' about forty strings are allocated. This can easily be avoided using write streams. The method could probably be made even faster by using #indexOfSubCollection:startingAt: and just copying with the correct size. I will post a patch but I first need an issue number that I can reference.

[Pharo-project] Debugger not closed issue ?
by laurent laffont Dec. 6, 2010

Dec. 6, 2010

Hi, can you check this please ? Take an image you work on (not a fresh one), and evaluate: Debugger closeAllDebuggers. Smalltalk garbageCollect. Debugger allInstances size. On a lot of my images 1 or 2 Debugger instances remains. It's a problem for Autotest, but it also may be a side effect of Autotest, so I want to check.

[Pharo-project] Image freeze because handleTimerEvent and Seaside process gone?!
by Adrian Lienhard Dec. 6, 2010

Dec. 6, 2010

Hi all, We've been experiencing an "interesting" problem: the image freezes and does not response to HTTP requests anymore after it has been running for days. Here some basic information about our setup: Squeak VM 4.0.3-2202 compiled with gcc 4.3.2 PharoCore 1.1 OS Debian Lenny amd64 (CPUs are 4 Intel Xeon E5530 2.40GHz) - We have never seen the problem with the Squeak VM 3.9-9 and Squeak 3.9 on the identical machine and with the same application source (modulo some adaptations to make it run on Pharo). - We run the VM with -mmap 512m -vm-sound-null -vm-display-null, and the UI process is suspended (Project uiProcess suspend) - VM does not hog the CPU and memory usage is normal - The meantime between failure is several weeks and we haven't managed to reproduce the problem - The application mainly serves HTTP requests. When the image does not receive requests for some time we send it a STOP signal, when a request comes in it is sent a CONT signal. - lsof shows TCP *:9093 (LISTEN) TCP server:9093->server:46930 (CLOSE_WAIT) Below is a GDB backtrace and the Smalltalk stacks from an image that was frozen (the VM had been running for almost 100 hours): ============================================================= (gdb) bt #0 0x08072020 in ?? () #1 <signal handler called> #2 0xb766f5e0 in malloc () from /lib/libc.so.6 #3 <function called from gdb> #4 0xb76c50c8 in select () from /lib/libc.so.6 #5 0x08071063 in aioPoll () #6 0xb778bb8d in ??

How comes these processes vanished? This may be related to Pharo or to the Squeak VM. Has anybody else seen this problem? Any idea how to debug/fix this issue is very much appreciated! Cheers, Adrian CCed to pharo-dev since this may be related to Pharo; please respond on the squeak-vm list

I guess you're barking up the wrong tree, because despite it's name squeaksource is run by the pharo guys. 2010/12/6 Casey Ransberger <casey.obrien.r(a)gmail.com> > > > -- > Casey Ransberger > > > >
