Those torrents are still stored on the Torrent FTP server. Could we
possibly just re-add those torrents/hashes back into the database. It
may take a while but I imagine it is still is possible.

In an attempt to copy the data that the torrent team entered into the
old database, I managed to wipe out the last 6 days of data. Go me!
So, this means that now everything from 5/23 to 5/30 is going to say
that it's real no mater what you use, since there aren't entries in the
database for it.


Anything that is being tested should be checked for mod 137 to determine
if it is ours or not for the next few weeks if the identifiers say it's
real. (The mod 137 check, of course, doesn't need to be done if it
returns that it is ours.) There is no way around this, since there is
no way to get the data back.


I'm also going to make a change to the hash identifier/torrent interface
that will screen out the garbage that some sites add to the torrent file
(which was causing false negatives). Expect the new versions tomorrow.
For now, just use the torrent interface (and stop using the hash
identifier already).

        Q: Dan asked what caused case 1.

        A: Some data was entered into the old database by Rendy and
Gerald (they must have been using the old version of the interface). I
am going to do another dump from the old database to the new database
for several tables (should only take a couple hours.) Will email when
the dump is finished.

                Oh ok, we can wait for the new version...

                But these errors are caused by the torrent interface
that's supposed to point to the correct DB. We're not just seeing errors
with the QA hash identifier.

                I sent an email last week to Dan that, I think, was CCed
to the QA team saying not to use QA's torrent hash identifier until I
had a chance to update it. The work around was to get the torrent
interface, since that is pointing to the correct database.


                I will make a new version of the hash identifier today
and email QA team when it is ready.

                        The hash identifier is reporting the hashes
incorrectly and reporting some errors. See below for details.

                        Here are the mislabeled hashes that I found on
the Universal Pictures 5-29-07 torrent results. Also currently getting
a "Database query error! (0x100B) bt_generator_maininfo" error when
trying to check hashes in the BT Interface.


                        1: Marked as Real by the BT Interface but
marked as Old Skool in the Hash Identifier






                        2: Marked as Real by the Hash Identifier but
marked as Old-Skool by the BT








                        3: Marked as Real by the Hash Identifier but
marked as Regular Decoys by the BT










                        4: Marked as Real by the Hash Identifier but
marked as 90% Decoy by the BT Interface
