In our nearest plans is make an automated (Hudson based) build setup for Cog and Squeak VMs. All files, which used for building an artifacts should be included in source code repository. So, most probably i will add the 'hudson-build' dir at same level as 'platforms', where scripts and configs will be stored. Some changes which i going to do: - all generated code will be removed from version controlled tree. Instead of it i will add an information, which will be enough to reproduce the generated code by taking 3 separate config file(s) a) image version (or its URL(s) for download) b) script for loading VMMaker (of concrete version) + all addons like FFI , FT2 etc etc into image c) script for generating the source code using VMMaker image .. z) tell me if i miss anything here With removing generated source code from repo we now can make sure that any changes in VMMaker (including code generation itself) can be tested and can be reproduced by build server at any snapshot version. Also, we could test & see if VMMaker loads well and can generate code using different base images. So, we will instantly know if any changes in compiler, or other layers of system is breaking VMMaker. Because having a years old image where VMMaker works 100%, but at same time have 100% chances that it couldn't be loaded (or even if loaded, but can't run correctly) in latest image is not what i think good practice for keeping your house clean. So, by getting rid any intermediate artifacts from build chain we will be able to make sure that: - VMMaker loads w/o problems in latest/multiple image(s) - VMMaker works well and can generate code That's means that for any newcomer, loading and building VM will be much less tedious process, and for 99% of cases it can be fully automated error free process. And let me remind our motto: we're not trying to produce perfect system/setup from first lucky shot. We slowly but steady crawling towards improved state of art. Any comments, ideas and suggestions are welcome. -- Best regards, Igor Stasenko AKA sig.
