Hi robert Describe a scenario: with reproduceable steps. Because you know we are a lot of load code from MC and we do not have problem.

[Pharo-project] ODBCWarning

by Schwab,Wilhelm K

The porting continues... It is getting closer to doing something. It just raised an ODBCWarning about the server changing the language to us_english. Any ideas? Either I do not care or should set it up front?? One thing really surprised me, and note that I might have brought this on myself (though I think that is unlikely) by messing with startup and shutdown: the ODBCLibrary was stubbornly clinging to the Linux library from my home machine. I finally used ODBCLibrary default initialize. which seemed to put an end to the separation anxiety. Is there a better fix? I suppose I should try this in a clean image to see if there is really a problem therein, but that will be a little hard to do without a lot of my code, almost any of which either depends on changes I have made or could have caused the problem. Maybe I should ask whether some of you use ODBC on Windows and Linux and have no problems moving between the machines. Bill

However as a thank you and for my own records, a small tutorial for your google code wiki: =Command-line Scripts with a Headless Pharo= For some tasks like benchmarking and automated testing, an integration with other tools comes in handy. For such use cases, Pharo can be used headless, i.e., without its graphical user interface. This brief tutorial will demonstrate how to use the Debian Language Shootout benchmarks with a fresh Pharo image. ==Step 1: Setup Pharo and a Fresh Image== * download a Pharo image, the sources file, and a VM from the [http://www.pharo-project.org/pharo-download download page] * extract all archives in the same folder * start Pharo, from the commandline, on a MacOSX it should look like this: {{{ "Squeak 4.2.1beta1U.app/Contents/MacOS/Squeak VM Opt" \ pharo1.0-10418-BETAdev09.08.3.image }}} ==Step 2: Load OSProcess== For output on the shell, we need an extra package from the SqueakSource repository. It can be loaded by simply executing the following code in a workspace window: {{{ ScriptLoader loadLatestPackage: 'OSProcess' from: 'http://www.squeaksource.com/OSProcess' }}} To execute this code snippet, select it and press cmd+d or use the "do it" item in the context menu. ==Step 3: Load Common Benchmark Code== Now we can load the common parts of all shootout benchmarks into our image. * On way to do this is to grab the code shown [http://shootout.alioth.debian.org/gp4/benchmark.php?test=all&lang=squeak&la… here ] and save it to a file called `common.st`. * Open the file browser from the Menu -> Tools -> File Browser. * Select `common.st` and press `filein` to load the code. Now you can close all windows in your image and save and quit it. ==Step 4: Run a Benchmark== * Grab the code of a benchmark like [http://shootout.alioth.debian.org/gp4/benchmark.php?test=fannkuch&lang=sque… Fannkuch ] * Save it to a file named like `fannkuch.st` * Add a run script to the end of the code in `fannkuch.st`, like this: {{{ Tests fannkuch. SmalltalkImage current snapshot: false andQuit: true. }}} * Run it with a headless Pharo: {{{ "Squeak 4.2.1beta1U.app/Contents/MacOS/Squeak VM Opt" \ -headless pharo1.0-10418-BETAdev09.08.3.image \ $PWD/fannkuch.st 6 }}} Best regards Stefan > > > -- > Damien Cassou > http://damiencassou.seasidehosting.st > > "Lambdas are relegated to relative obscurity until Java makes them > popular by not having them."
