how much does it cost to run all of anime tosho?

Thanks!

Correct, it's only intended to match the first file in the torrent.

Correct.

Oh, I see the problem now. Thanks for your explanation. The last block of the file might contain information from the next file, and since that would be included in the block hash, it wouldn't be useful for detecting duplicates.

My thought process was to split the file into blocks and hash the partial last block, but I didn't consider the interaction with torrents containing multiple files.

Sorry to be a bother, but if I understand correctly, this would also not allow for detecting duplicate files that aren't aligned to block boundaries, is that the case?

It would also be nice to know the rich text formatting used on this feedback page. Figured it out, it's pseudo-HTML.

Another minor question: the documentation says "CRC32" a lot sometimes, which CRC polynomial is actually used here? The Ethernet one?

As opposed to including the partial block at the end? If so, I don't see how you could make it work.

Keep in mind that the point is to provide an indicator to detect duplicates. Arguably it's not 100% accurate, but it should be close.
You don't know how the partial block at the end will be filled - if it's the last block of the torrent, it isn't padded, if it's not the last block, it's filled with the contents of the next file. There's no way to compute the hash for the latter case, since you can't anticipate what file will be concatenated onto the end. The former case is computable, but would only be useful to match against torrents where that file is at the end and the file's offset is block aligned - basically it'd only be useful for matching against single file torrents, but useless for matching batches.

(Does this use BBCode?)

Ah, of course, my bad. Ditto for duplicate detection though, files with different trailing data will hash equal. Is there a reason it's done this way? In any case, it's not like it can be changed at this point, and even if, it would be of small benefit, if any. Thanks for the quick response.
