Well, I suppose this is one thing I would find very attractive, a sort of appeal to conservatism; since we are holding people's crown jewels, we should be extra careful. > > The major hassle of this solution is that requires sqlite + HDBC (or > something like that) as dependencies, but I think that this is > something we can work on (sqlite can be "embedded" as a large .c file > in any application). Seems like we would run into something like this in any case. Also... I'll add for the record that I have not learned how filesystems are implemented, so should you someday submit a patch for this feature, I would be inclined to pass up the code review to somebody more experienced. Out of curiosity, how does one encode something filesystem-like in something database-like? Do you do something stupid and simple like associating paths with whatevers "foo/bar/baz" => whatever1 "foo/bar/baz/quux" => whatever2 And write a bunch of wrapper code around it (if you delete 'foo/bar/baz' go hunt after everything that starts with 'foo/bar/baz/' and delete it too)? Or do you do something far more clever? Do feel free to answer the above question with a simple 'go learn about filesystems and the answer will be obvious'. I certainly do not expect you to sit down and educate me. Cheers, -- Eric Kow http://www.loria.fr/~kow PGP Key ID: 08AC04F9 Merci de corriger mon français.
