Mac OS Performance
by Bert Freudenberg 21 Mar '05

21 Mar '05

I just did some tinyBenchmarks on the latest Mac VMs (attached below). It appears that bytecode speed is higher for Ian's VM, but went down a tad from 3.6 to 3.7. More importantly though, send speed is higher in John's VMs, and even though it went up in Ian's latest it still is not at the level of John's. In both cases it's a 10-15% difference, which is not that important, but still significant ... - Bert - This is an iMac G5 1.6 GHz, using the precompiled VMs Ian 3.6-3 '127744510 bytecodes/sec; 4655980 sends/sec' '128837443 bytecodes/sec; 4665225 sends/sec' '130545639 bytecodes/sec; 4662139 sends/sec' '130346232 bytecodes/sec; 4550777 sends/sec' '129685916 bytecodes/sec; 4527395 sends/sec' Ian 3.7-7 '112974404 bytecodes/sec; 4788828 sends/sec' '113374667 bytecodes/sec; 4811709 sends/sec' '111111111 bytecodes/sec; 4785577 sends/sec' '113174182 bytecodes/sec; 4898648 sends/sec' '113174182 bytecodes/sec; 4746905 sends/sec' John 3.7.5Beta3 '108658743 bytecodes/sec; 5141615 sends/sec' '108566581 bytecodes/sec; 5156660 sends/sec' '106224066 bytecodes/sec; 5252723 sends/sec' '105960264 bytecodes/sec; 5141615 sends/sec' '105090311 bytecodes/sec; 5175591 sends/sec' John 3.8.7Beta1 '108291032 bytecodes/sec; 5256640 sends/sec' '111401218 bytecodes/sec; 5115497 sends/sec' '111401218 bytecodes/sec; 5300116 sends/sec' '107292539 bytecodes/sec; 5002948 sends/sec' '107925801 bytecodes/sec; 5344317 sends/sec'

For auto-detection of X11 library and header locations to work, you (an anonymous, generic 'you') must have /usr/X11R6/bin (or equivalent) in your PATH and you must have a working 'xmkmf' in that location. In other words: to build Squeak with X11 support your compilation environment must be capable of building X11 clients from source. (Sounds obvious when put like that, no?) Otherwise you can bypass X11 auto-detection by running configure manually: mkdir bld .../config/configure --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib make (assuming the required X11 headers and libraries are installed). If you get compilation errors after configuring with '--without-x' (including OpenGL-related errors on Mac OS X) then let me know, because you've found a real bug. Cheers, Ian PS: I only saw the above email because of a broken imap server. Send VM build problems to VM-Dev or to the maintainer of the affected VM. Thanks.

[VM][ENH][VMMaker] CPP directive translation for SLANG
by David T. Lewis 21 Mar '05

21 Mar '05

This change set adds support for the C preprocessor to SLANG. Two new methods are supported: Object>>cppDirective Object>>cppIfDef:inSmalltalk:comment:ifTrue:ifFalse: Examples: The Smalltalk expression: self cppDirective: 'ifdef HAS_FOO'. self doFooStuff. self cppDirective: 'endif'. is translated to: # ifdef HAS_FOO doFooStuff(); # endif The Smalltalk expression: self cppIfDef: 'HAVE_FOO' inSmalltalk: [if self haveFoo] comment: 'some platforms do not support foo properly' ifTrue: [self doThingsThatWorkIfFooIsPresent] ifFalse: [self doSomethingElseInstead]. is translated to: # ifdef SOMETHING // system supports foo doThingsThatWorkIfFooIsPresent(); # else doSomethingElseInstead(); # endif // SOMETHING Here is an example of a method that uses the C preprocessor: primitiveUnsetEnv "Unset an environment variable." | cStringPtr keyString | self export: true. self var: 'cStringPtr' declareC: 'char *cStringPtr'. keyString _ interpreterProxy stackObjectValue: 0. cStringPtr _ self transientCStringFromString: keyString. self cppIfDef: 'HAVE_UNSETENV' inSmalltalk: [true] comment: 'unsetenv() is not portable' ifTrue: [self unsetenv: cStringPtr] ifFalse: [interpreterProxy primitiveFail]. interpreterProxy pop: 1 The generated C code in the plugin is: EXPORT(int) primitiveUnsetEnv(void) { int keyString; char *cStringPtr; keyString = interpreterProxy->stackObjectValue(0); cStringPtr = transientCStringFromString(keyString); # ifdef HAVE_UNSETENV // unsetenv() is not portable unsetenv(cStringPtr); # else interpreterProxy->primitiveFail(); # endif // HAVE_UNSETENV interpreterProxy->pop(1); } Dave

Mpeg3Plugin
by Ian Piumarta 20 Mar '05

20 Mar '05

The Mpeg3Plugin will not compile using vendor tools on Solaris. (One function is inlined out of existence, then referenced without declaration from within another file, causing the link to fail.) Unless someone objects within the next 30 minutes, I am committing a change to platforms/Cross/plugins/Mpeg3Plugin/libmpeg/video/motion.c as follows: -INLINE void mpeg3video_calc_dmv(mpeg3video_t *video, +#if !defined(sun) +INLINE +#endif +void mpeg3video_calc_dmv(mpeg3video_t *video, Time is now Sat Mar 19 12:28:26 PST 2005. You have until 12:58:26 to complain. Ian

Proposal: utf32Code in sqKeyboardEvent
by Andreas Raab 19 Mar '05

19 Mar '05

Folks, Since I'm not sure all of you have followed the discussion about scroll events (which then went into keyboard events) here's my proposal again: I would like to add a utf32Code field to sqKeyboardEvent which serves the purpose to provide a UTF-32 value if the VM provides extended input services (the Mac VM already does; others will surely follow). The utf32Code field only needs to be filled in for EventKeyChar events (e.g., neither for EventKeyDown or EventKeyUp since those are used for reporting keys not characters). John is already playing with this but I want to make sure there is general agreement on this issue. Ian, Tim? Any extra comments? Cheers, - Andreas

Scroll events
by Bert Freudenberg 19 Mar '05

19 Mar '05

Scroll events really should be mouse events (*). This hasn't been too much of a problem in Morphic where we have a focus-follows-mouse policy. But in Tweak, for example, the keyboard scroll events go to the focused pane even when I point the mouse somewhere else. AFAIK no host platform originally delivers scroll events as keyboard events, so it appears as the Right Thing to do, rather then hacking around it on the image side. However, I'm not sure about the best way to actually hand this to the image ... Any opinions? As a further data point, there are mice having both vertical and horizontal scroll capabilities, something that users may want to put to use. Not sure if we should support the additional buttons, too, but why not? My mouse has 8 of them in total, all of which do something reasonable - yes I'm on a Mac ;-) [OT] Rumor has it that Apple is going to introduce a new mouse soon, which may have two buttons or an iPod-like wheel or both ... - Bert - (*) Yes, I'm guilty for coming up with the arrow-key hack in the first place, but it was TSTTCPW
