Hmm.. a frustrating results: 1 tinyBenchmarks - VM built with gcc-2.95.2 '178025034 bytecodes/sec; 5308098 sends/sec' '174268209 bytecodes/sec; 5502853 sends/sec' - VM built with latest gcc, available from mingw binaries gcc 3.4.2 (mingw-special) '99843993 bytecodes/sec; 4512903 sends/sec' '101105845 bytecodes/sec; 4512903 sends/sec' Interesting, that it feels more responsive when built with 3.4.2 :) ----- P.S. To ones, who might want try to build Hydra VM. Here the list of plugins which known to be able to build with: ADPCMCodecPlugin B3DAcceleratorPlugin B2DPlugin BitBltPlugin BMPReadWriterPlugin ZipPlugin DropPlugin DSAPrims FFTPlugin FilePlugin FloatArrayPlugin FloatMathPlugin GeniePlugin HostWindowPlugin JoystickTabletPlugin JPEGReaderPlugin JPEGReadWriter2Plugin Klatt LargeIntegers LocalePlugin Matrix2x3Plugin MiscPrimitivePlugin Mpeg3Plugin RePlugin SecurityPlugin SocketPlugin StarSqueakPlugin SurfacePlugin UUIDPlugin - external SqueakFFIPrims -- Best regards, Igor Stasenko AKA sig.

HTTPClient that can return the http code, headers and response?
by Danie Roux 25 Dec '07

25 Dec '07

All, Is anyone aware of a HTTPClient that can return the following: - The HTTP code (404, 200 etc.) - The HTTP headers - The HTTP response ... and also supports the HTTP methods DELETE, OPTIONS and HEAD. The standard HTTPClient throws away all that and just return the HTTP response as a string. -- Danie Roux *shuffle* Adore Unix - http://danieroux.com

Testing equality of blocks
by Keith Hodges 24 Dec '07

24 Dec '07

I am wanting to test the equality of blocks, as are the two blocks that I have defined in the same method context. I vaguely remember some mention of a "fix" for this... any pointers would be appreciated thanks in advance Keith

OSProcess weirdness
by Jon Hylands 23 Dec '07

23 Dec '07

Hi everyone, (I tried to send this message to David last night, but bounced, so I'm reposting it to the list...) I'm using OSProcess on my gumstix (Linux) to run some external commands like ps, and it fails after the first command. I have tracked down the reason it is failing, and it appears to be a bad lingering dependent for the ThisOSProcessAccessor singleton. I log the following when I start: Starting server... OSProcessAccessor forThisOSProcess: a UnixOSProcessAccessor on pid 2040 ..dependents: #(a WindowsProcess with pid 2040 a UnixProcess with pid 2040) So it looks like the release for dependents isn't working in OSProcessAccessor >> #startUp: I'm using OSProcess version 4.3.3 on Squeak 3.7, doing development on Windows, and copying the image over to the gumstix to start it headless. Any thoughts? Have you seen this before? Later, Jon -------------------------------------------------------------- Jon Hylands Jon(a)huv.com http://www.huv.com/jon Project: Micro Raptor (Small Biped Velociraptor Robot) http://www.huv.com/blog

[ANN] CommandShell 4.2.1
by David T. Lewis 23 Dec '07

23 Dec '07

CommandShell 4.2.1 is now on SqueakMap and the Squeak 3.10 Universe. - Home page: http://wiki.squeak.org/squeak/1914 - CommandShell overview: http://wiki.squeak.org/squeak/2153 - Using Squeak as a unix shell: http://wiki.squeak.org/squeak/6023 This is a substantial rewrite of CommandShell 3. It uses event driven I/O when the AioPlugin is available; otherwise it relies on polling loops similar to CommandShell 3. Shell syntax is now separated from the CommandShell, and different views permit graphical windows based on Transcript (Morphic and MVC), or an external teletype style view for interacting with a headless Squeak from a command line. CommandShell 4.2.1 works with GraphViz, but has not been tested with any other packages that may depend on it. OSProcess version 4.3.5 or greater is recommended, as a concurrency bug has been addressed that previously caused intermittent failures in the CommandShell test suite. If AioPlugin is used, version 2.2 or greater is recommended. Earlier versions had a bug that limited the number of file handles to 19, causing intermittent problems in the CommandShell test suite. Note that AioPlugin may not be included with your VM, even if OSProcessPlugin is present. VM builders may find AioPlugin, OSProcessPlugin, and XDisplayControlPlugin on SqueakMap, SqueakSource, and on the swiki. The MVC environment is broken on some Squeak images (notably Squeak 3.10), so CommandShell does not work under MVC in those images. The prior version (CommandShell 3.0.5) remains available on SqueakMap and the Squeak 3.10 Universe. - Dave
