I tested pharo-core 1.2 as well as a seaside image based on pharo 1.1 with Glorp and PostgreSQL: everything worked as expected. I did a quick benchmark on that last image: where I used to get 70 requests/second I now get 230 requests/second. This is really amazing. Thanks Eliot, John and everybody else who made this possible. I hope the linux VM is equally fast. Sven

Thanks John. It seems this is even a little faster (at least with tinyBenchmarks) than the image produced by Eliot john 10 tinyBenchmarks '721126760 bytecodes/sec; 55015015 sends/sec' 10 tinyBenchmarks '717589348 bytecodes/sec; 55483560 sends/sec' 10 tinyBenchmarks '706206896 bytecodes/sec; 55562428 sends/sec' eliot 10 tinyBenchmarks '626682986 bytecodes/sec; 54326849 sends/sec' 10 tinyBenchmarks '625152625 bytecodes/sec; 54251448 sends/sec' 10 tinyBenchmarks '630153846 bytecodes/sec; 54326849 sends/sec' A difference I found with Eliot VM and your previous ones is shortcuts. In eliot image, to select words, I do shift + ctrl + narrow, or shift + command + narrow. In yours, I only can do shift + command + narrow. And if I do shift + ctrl + narrow the mouse cursos doesn't even move. cheers mariano On Thu, Aug 26, 2010 at 12:12 AM, John M McIntosh < johnmci(a)smalltalkconsulting.com> wrote: > I've stuck a version (5.8b3) of the cocoa based os-x squeak cog JIT based > VM in my experimental folder. > > http://homepage.mac.com/johnmci/.Public/experimental/Squeak%205.8b3.app.zip > > This VM is built from the Cog sources (with some minor changes for the > iPhone) & revised & fixed Socket Plugin. > It currently does NOT contain any external plugins.

Re: [Pharo-project] String to Number conversion

by Schwab,Wilhelm K

'3foo' asInteger probably should fail, because there is no stream to be tested for #atEnd. Reading '3foo' from a stream *probably* should be ok by default, becauuse the stream will clearly not be a the end, one could easily want to read integers out of formatted strings. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Johan Brichau [johan(a)inceptive.be] Sent: Thursday, August 26, 2010 8:43 AM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] String to Number conversion On 25 Aug 2010, at 09:26, StÃ©phane Ducasse wrote: >> Did you mean to let the dirty stuff to #squeezeOutNumber and throw the error in the #readFrom:? > > Yes. Now we should identify user of readFrom: that in fact are expecting squeezeOutNumber and fix them. Well, it seems that the current readFrom: only requires the string to _start_ with a valid format. This means that: '3foo' asInteger = 3 Should we not fail here too? What are the opinions?
