Other version control systems simply treat text and binary files differently. No smart(ass) logic doing the wrong thing. A text file gets processed on check-in AND checkout depending on it's type and the client setting. Some heuristics may be applied when adding files. i.e look-up according to magic cookies or looking for bytes that simply do not occur in text files (e..g a nul byte). Those few systems that I know about treat the type as a file (as opposed to a version specific) attribute. Some systems have lots of file types, not just text and binary. Encoding is about the only thing that would interest me, although not terribly important (except the file name), but that may be off topic for this thread. The hash-on-the whole-tree might be a reason for making the attribute version-specific. Mercurial's filters sounds like a good way to implement file types in a generic way as long as git's excellent performance isn't hurt. > I'm absolutely _not_ suggesting merging that patch as-is or even in any > form very close to it.

Do people apply your patches right away, like it's some god-like commandments? -- robin - : send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
