2010-07-02 19:46 <paepke> i have a question regarding the ir.attachment. that collision field is for the case that two files have the same md5sum?
2010-07-02 19:48 <paepke> thats how i read the code. just wanna be sure

2010-07-02 20:33 <cedk> paepke: yes
2010-07-02 20:34 <paepke> cedk, are you satisfied with that functionality?
2010-07-02 20:35 <paepke> i'm currently looking into enhancing that module for a customer
2010-07-02 20:51 <paepke> cedk, have you already thought about changing the hashing algorithm to sha1? I'd like to allow a single instance storage with that.
2010-07-02 20:58 <paepke> cedk, i wanna ask if you would accept such a patch
2010-07-02 21:07 <cedk> paepke: why changing?
2010-07-02 21:11 <paepke> cedk, cause sha1 has currently no exploit for generating the same hash. for single instance storage i don't wanna use that collition field.
2010-07-02 21:12 <paepke> with md5 its possible to have the same md5 for different files.
2010-07-02 21:37 <cedk> paepke: with sha1 also
2010-07-02 21:38 <cedk> paepke: and it will be for any hash algorithm
2010-07-02 21:38 <paepke> cedk, but its nearly impossible. other projects like mercurial are also relying for file checks
2010-07-02 21:39 <paepke> cedk, i agree that its possible with any hashing algorithm.
2010-07-02 21:40 <cedk> paepke: I don't see any goals with this change
2010-07-02 21:40 <cedk> paepke: the hash is only used to detect same data and then store only one
2010-07-02 21:40 <paepke> cedk, with the current collition system we aren't able to implement a single instance storage.
2010-07-02 21:41 <cedk> paepke: with any hash, you will still need to collision check
2010-07-02 21:41 <paepke> cedk, really?
2010-07-02 21:41 <cedk> paepke: except if you accept the risk
2010-07-02 21:41 <cedk> paepke: still I don't see any goals
2010-07-02 21:42 <paepke> cedk, really stored only once? i assumed it has a -1 on that file name?
2010-07-02 21:42 <cedk> paepke: what do you call "single instance storage"?
2010-07-02 21:42 <paepke> cedk, to store it only once. thats what you said. but i can't read that in the code.
2010-07-02 21:42 <paepke> cedk, maybe i'm to dumb to find the correct snippet
2010-07-02 21:43 <cedk> paepke: it is the case
2010-07-02 21:44 <cedk> paepke: just try
2010-07-02 21:44 <paepke> cedk, i'm doing :-)
2010-07-02 21:53 <paepke> cedk, ok. you were again totally right. i misinterpreted how the collision occurs.
2010-07-02 21:54 <paepke> i shouldn't doubt the tryton code you guys wrote ;-)
