Hi Guido, I have Samsung Galaxy Pad for a week now and I'm really interested to have a Smalltalk on it. So, you have all my moral support for your work!

[Pharo-project] Waste of CPU Power by polling events?

by Guido Stepken

I am just porting squeak/Etoys to Samsung-PAD and i noticed some strange things: In Pharo 1.1 network connections seemed to be limited to 4 connections: In the listenLoop backlogSize is set to 4. Means - Pharo is limited to max. of four simultaneous TCP Connections? But: Some MacIntel VM seem to run Squeak with additional worker thread for event processing. Maybe this limitation may not occur here? Carbon ports of Pharo use ioPeekKeystroke, ioGetKeystroke, ioMousePoint, ioGetButtonState instead of kEventRawKeyModifiersChanged and kEventMouseMoved event Found in Pharo so far: isDraggingEvent isDropEvent isEditEvent isKbdEvent isMorphicEvent isNoteEvent isTempoEvent isWindowEvent Hmmm ... quite a lot of events being polled: Need additional: isOnMouseOverEvent isMouseGestureEvent isTouchGestureEvent isNetworkEvent isUSBEvent isSerialEvent isParallelPortEvents isCtrl-C-Event ... I fear, that this costs a lot of wasted VM Power by polling. UNIX, especially Linux is changing towards a event machine, driven by interrupts. So - Interpreters should also migrated from polling to interrupt driven event-machines. I am missing that in Pharo. Pharo still has too much polling code/algorithm running, that slows down Pharo/Squeak/Etoys ... unneccessarily. Any ideas appreciated ... tnx, regards Guido Stepken

Re: [Pharo-project] FileDirectory default is wrong in MacOS

by John M McIntosh

Likely a bit of history is needed here. The original file logic for macintosh OS 7.5.5 worked with HFS, later I guess it was 8.x Apple introduced HFS+ which allowed for files names to be longer than N where N was mmm 26 or 32? That would be the check for 255 characters. So we had to deal with pre HFS and post HFS+ systems. Later when os-x came out I had to rewrite the file lookup logic to properly handle symbolic links and os-9 aliases, then earlier in the last decade it became apparent that Apple was moving the developer community from using OS-7.x.x file naming conventions to unix naming convention. So again some nasty bit of logic to help the image and the VM sort between is it HFS, HFS+, pre os-x names, or post os-x names (255 chars & case insensitive). In all this Apple decided to go with case insensitive file names, but on the os-x server case sensitive. Now of course you can switch but that sometimes leads to interesting problems. So one is that you can have four volumes mounted, each of which has different case sensitivity, so it's not the operating system that drives case or no, it's the volume. When I looked at this 10 years back it was *difficult* to drag the information about the volume out of the OS, now it's easier, but mounting NFS etc perhaps makes things a bit fuzzy again. However this issue is a problem because you can't do "FileSystem isCaseSensitive" it's more like "FileSystem isCaseSensitiveForVolume: volume" Clouding that is of course the fact what is a volume across different OS? and of course in unix you can have mount points so it's unclear how you know... Anyway as you see a bit of restructuring would need to be done because you have to consider each file path differently.

Comment #12 on issue 1594 by patchi...(a)gmail.com: refactor to use #ifNil: http://code.google.com/p/pharo/issues/detail?id=1594 It would be great to review this issue cause it's on Accepted state and i lots of ppl don't agree with it. Ocurrences of = nil or ~= nil were no more than ten but there're at least 800+ ocurrences of == nil or ~~ nil in PharoCore image so far.
