Re: [HiveMind] implementing module dependencies

[Luke Blanshard]

Sure, I have an opinion.  I think the Eclipse-type all-possible-relationships is overkill.  However, I don't like Howard's two relationships as the set HiveMind supports either. I'd like to see your "compatible" as the default meaning: the major number must match and whatever part of the rest of the number is given is the minimum version within that major version.  Maybe we should also support an exact match, perhaps by prefixing the version number with "=". The whole world seems to be moving toward a common definition of software version numbers, with a change to the major number meaning that backward compatibility is not preserved, and the lesser numbers meaning that it is.  Let's do our part to fit in with that model, and help spread it.

The former would be "perfect", the later would be "greaterequal". You may have noticed that in general I prefer more complex solutions but in this case, my gut feeling is that "less is more". Need to come up with percise, codable defintiions of all those match types. I think it could be useful to distinguish between more than just "perfect" and "greaterequal" matches. For instance it is quite common to use the major version to indicate a refactored and backwards incompatible version. And minor versions often just indicate added features, but otherwise backwards compatible. Thus for a dependency the following would be possible: - no version or match attribute -- any version of "other.module" required - only version given -- would use the default "compatible" match for given version - version and match="greaterequal" -- all 3 parts of the version must be greater or equal - version and match="compatible" -- major must match and others must be greater or equal - version and match="equivalent" -- major and minor must match and last is greater or equal - version and match="perfect" -- all 3 parts of the version must match --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
