Hi All,
my guess is that your problem is the reliability of a trading system deployment. Checksum does not ensure that deployment is successfull and the deployed system is working. It is just a help to troubleshoot an already failing system!
I think it should be addressed with a decent "design - code - test - build - deploy" development cycle. Source control tools are part of this process. They help coding, but they do not replace build and deloy phase.
Once this process is in place there is no need to use checksum. If you still find something suspectfull you can use windiff (compare files and directories) or other tools to quickly detect the problem.
To give you some hints, here is my cheep solution for AFLs:
I code in a work folder that AmiBroker do not use directly. (This is where I have my source control sw set up.)
When I'm done with coding I run a project build script (simples cmd file) that copies all afls in that project into a folder stucture similar to AmiBroker's folder structure.
This project folder stucture is DELETED AND RECREATED at each builds from the actual sources! After build has run I have a complete set of files for that project. It has a deploy command (simple cmd file) as well, that will copy all files to the local AB folders.
If I'm on my dev machine I run the build and deploy cmds one after another and I test my coding. If I find any coding error, I fix it in the work directory and start over again. (build and deploy is only 1 second.)
Once all bugs are removed, and project is tested, I need to label my source files, save and label the last project folder structure and copy it to target machines. There I run the SAME deploy.cmd as on the dev and test machines.
My "general includes" was a separate project. If I "touched" it, I rebuilt all other projects and tested them all. This project was always deployed with the other projects that used it.
It is now a plugin. This plugin's latest version is also deployed along any AFL project.
I keep the last deployed project structure on the target machines. If I would find any issue I just compare its files against files in AB's folder.
Regards,
Y
