General Information

Author: Exp & Epoximator
Version: 0.03.035 (2007-05-06)
Version number used for protover parameter: "3"

IMPORTANT INFORMATION FOR ALL INTERESTED:

  • If you are mainly interested in notifications and private messaging, check out our Jabber and RSSRDF support first.
  • The UDP API is not an appropriate choice if you desire to download a local copy of the AniDb database.
  • If you want to create a client you have to register it here and here.
    • Check out the clients that are being developed. There exists usable code in many different languages already.
  • If you have suggestions for improvements or new features use the development page.
  • Please also take a look at the API page.

Formats used in this Spec

  • {vartype varname} - Specifies what shall be inserted at this point and its type.
  • [...] - Everything between [ and ] is optional.

Used types

  • int2 - 2 byte Integer (in string representation)
  • int4 - 4 byte Integer (in string representation)
  • boolean - true or false - use '1' for true, '0' for false
  • str - String (UDP packet length restricts string size to 1400 bytes)
  • hexstr -- a hex representation of a decimal value, two characters per byte. If multiple bytes are represented, byte one is the first two characters of the string, byte two the next two, and so on.

Content Encoding

  • Default character encoding: ASCII
  • Escape scheme for option values (to server): html form encoding + newline
    • This means you have to encode at least & in your option values in html form encoding style (&) before sending them to the api server. All other html form encodings are optional.
    • All newlines should be replaced by <br />
  • Escape scheme for returned data fields (from server): ', | and newline
    • Newlines are encoded as <br />, ' is encoded as ` and | is not allowed in data fields.

Basics

General

The network communication is packet and line based. Each ANIDB API command is exactly one UDP packet containing one line. Results are sent as one packet but may consist out of multiple lines. A return value always starts with a 3 byte result code followed by a human redable version of the result code. Be aware that important data fields may be returned directly after the return code (see: 200,201,271,272,504). The meaning for all result codes can be found in this document. If there is more than one entry returned, it's one entry per line. Lines are terminated by a \n (no dos linefeed \r). The elements of a format string are seperated by a "|" character.

{three digit return code} {str return string}\n
{data field 0}|{data field 1}|...|{data field n}

IMPORTANT:

  • All commands except PING, ENCRYPT, ENCODING, AUTH and VERSION requires login, meaning that the session tag must be set (s=xxxxx).
  • A client should ignore any additional trailing data fields it doesn't expect. Additional fields are going to be added to the output of some commands from time to time. Those additional fields will simply be appended to the end of the existing output. A client should be written in a way so that it is not affected by such new fields.
  • Due to the length constraints of an UDP package (over PPPoE) the replies from the server will never exceed 1400 bytes. String fields will be truncated if necessary to ensure this. No warnings are given when this happens.
  • A client should handle all possible return codes for each command.
    • Possible return codes for all commands:
      • 505 ILLEGAL INPUT OR ACCESS DENIED
      • 555 BANNED
        {str reason}
      • 598 UNKNOWN COMMAND
      • 600 INTERNAL SERVER ERROR
      • 601 ANIDB OUT OF SERVICE - TRY AGAIN LATER
      • 602 SERVER BUSY - TRY AGAIN LATER
    • Additional return codes for all commands that require login:
      • 501 LOGIN FIRST
      • 502 ACCESS DENIED
      • 506 INVALID SESSION
NOTE: The '555 BANNED' message should not be expected by the client. This message is only enabled temporary to help developers understand what they are doing wrong.
NOTE: While in daily maintenance the AniDB API will reply with

601 ANIDB OUT OF SERVICE - TRY AGAIN LATER

to all commands. If a client recieves such a return value it should wait at least 30 minutes before trying again.

Server / UDP Connection

The Client has to send data packets to:

  • Server: api.anidb.info
  • Port: 9000/UDP

The servername and port should not be hardcoded into a frontend but should be read from a configuration file.

Server Errors

  • At any time the API might return a fatal error of the form:
6xx ERROR DESCRIPTION
  • Possible codes are 600-699.
  • Occurrences of these errors (except 601) should be reported to Ommina.
NOTE: 6XX messages do not always return the tags given with the command which caused the error!

Connection Problems

There are many ways for a client to end up banned or the API might currently be handling too many concurrent connections. If a client does not get any reply to an AUTH command it should start to increase the retry delay exponentially with every failed login attempt. (i.e. try again after 30 seconds if the first login attempt failed, if the second fails too retry after 2 minutes, then 5 minutes, then 10 minutes, then 30 minutes, ... until you reach a retry delay of ~2-4h.)

Local Port

A client should select a fixed local port >1024 at install time and reuse it for local UDP Sockets. If the API sees too many different UDP Ports from one IP within ~1 hour it will ban the IP. (So make sure you're reusing your UDP ports also for testing/debuging!)

The local port may be hardcoded, however, an option to manually specify another port should be offered.

Note when behind a NAT/masquerading router:
A session between the server and a client is identified by the ip and port used by the client. So when the port (or ip) changes within a session the client has to authenticate again. If a client is behind a nat router it can’t actually control the local port used for the connection. The router will normally translate the port to support several computers on a lan to share the internet connection. The public port (as determined by the router and seen by the server) which has been assigned to the connection will only be reserved for as long as it is in use. This means that the router will usually deallocate the port after a fixed timeout period (i.e. 5, 10 or 15 minutes). Once that happens the client will no longer be able to receive UDP messages from the server (the messages will be discarded as undeliverable by the router) and a new port will be selected once the client tries to send a message to the server (which will result in a new connection session - NOTE: this could get you banned!, see above). So in order to keep a session over a NAT router alive, the client has to ping the server within this period to prevent a timeout.

The client can decide whether it is behind a NAT router or not by adding nat=1 to the AUTH command. This will cause the response to include the ip and port as seen by the server. If the port differs from the port reported by the local socket, the connection subject to NAT and the client should issue PING commands in regular intervals. Please do not send pings more often then once every 5 minutes and only on connections via NAT routers or if the user has explicitly enabled regular keepalive pings via a configuration setting (default setting should be OFF).

Flood Protection

To prevent high server load the UDP API server enforces a strict flood protection policy.

  • Short Term:
    • A Client MUST NOT send more than 0.5 packets per second.
    • The server will start to enforce the limit after the first 5 packets have been recieved.
  • Long Term:
    • A Client MUST NOT send more than one packet every 30 seconds over an extended amount of time.
    • An extended amount of time is not defined. Use common sense.

Once a client exceeds a rate limit all further UDP packets from that client will be dropped without feedback until the client's packet rate is back down to acceptable levels.

NOTE: Dropped packets are still taken into account for the packet rate. Meaning if you continuously send packets your client will be banned forever.

Generally clients should be written in a way to minimize server and network load. You should always keep that in mind.

Abusive clients may be banned completly.

NOTE: If you suddenly stop getting replies from the AniDB API or you normally don't have a noteable packetloss and from one point on you suddenly note a high packetloss percentage you have most likely entered a critical flood ratio.

If the AniDB API isn't answering at all it might either be down or you have been banned, this is normally caused by vialoating the API specs (i.e. too many connections using different ports from one ip, too many auth failures, ...) (usually lasts 30 minutes). If you're experiencing packet loss you have probably reached the rate limit and the API starts to randomly drop incoming packets from your IP. (can be solved by enforcing a delay between multiple commands when you're sending a batch)

Anti Leech Protection

The API should not be used to "download" AniDB. If such attempts are detected you will get banned.

Caching

To minimize server and network load a client should use local caching in order to prevent repeated API requests for the same data.

A client should locally cache FILE/EP/ANIME/GROUP/... info wherever possible for extended amounts of time. (I.e. if a client is used to scan a local folder with anime files and add them via API to a users mylist then it shall only ask for all files in the first run and cache the info for all files known to AniDB. If run again over the same folder it shall only check those files which were unknown to anidb at the time of the last check.)

Later versions of the API might enforce this by banning clients which ask for the same information more than once every week/month.

Tag option

The api will add a user defined string at the beginning of each reply line seperated with a space, if desired.

  • To enable add the tag={str usertag} option to a command.
  • A tag is only valid for the command it was send with, meaning it is not persistent. If you want to have tags in front of all reply lines you will have to append the tag option to each command you send to the server.
  • Tags are ment to enable a client to handle more than one request/reply at a time.

Usage example:

 AUTH user=baka&pass=baka&protover=25&client=someclient&clientver=1&tag=abc123
 abc123 200 Jxqxb LOGIN ACCEPTED

or

 LOGOUT s=Jxqxb&tag=byebye
 byebye 203 LOGGED OUT
NOTE: The tag option is valid for all api commands and is thus not explicitly listed in the description of each command.

Data Indexes (fid,aid,eid,gid,lid)

  • All indexes start at 1 (not 0).
  • It is possible for table entries to have id fields with a value of 0 (i.e. gid). Those are to be interpreted as "NONE" or "NULL".
  • An ID is never reused. That means after an entry is deleted no new entry will ever have that ID again.
  • Mylist IDs (lid) are globally unique, not per-user unique.

Authing Commands

NOTE: _ANY_ command which requires parameters may return: 505 ILLEGAL INPUT OR ACCESS DENIED

AUTH: Authing to the AnimeDB

Command String:

  • AUTH user={str username}&pass={str password}&protover={int4 apiversion}&client={str clientname}&clientver={int4 clientversion}[&nat=1&comp=1&enc={str encoding}&mtu{int4 mtu value}]

Possible Replies:

  • 200 {str session_key} LOGIN ACCEPTED
  • 201 {str session_key} LOGIN ACCEPTED - NEW VERSION AVAILABLE
  • 500 LOGIN FAILED
  • 503 CLIENT VERSION OUTDATED
  • 504 CLIENT BANNED - {str reason}
  • 505 ILLEGAL INPUT OR ACCESS DENIED
  • 601 ANIDB OUT OF SERVICE - TRY AGAIN LATER

when nat=1

  • 200 {str session_key} {str ip}:{int2 port} LOGIN ACCEPTED
  • 201 {str session_key} {str ip}:{int2 port} LOGIN ACCEPTED - NEW VERSION AVAILABLE

Info:

NOTE: The password is the normal AniDB website password! The password listed in the profile as API Password in only used for the optional encryption feature.
  • The session_key is a String containing only a-z,A-Z,0-9 chars of a length of 4-8 characters.
It has to be stored by the client and needs to be sent as parameter with every command which requires the user to logged in.
  • The session_key String is appended as parameter "s", i.e. "PUSH notify=1&msg=1&s={str session_key}".
  • On a 500 LOGIN FAILED message the client should request the user to enter username and password again.
  • In case of a 501 LOGIN FIRST message the client should silently resend an auth command and send the failed command again.
  • A 502 ACCESS DENIED message should abort the current action on the client side and display a message to the user.
  • A 503 CLIENT VERSION OUTDATED message states that the udp server has been updated and does not support your client any longer. (protover is too low). A 201 message referes to a new version of the client software.
  • A 506 INVALID SESSION means that either the session key parameter "s" was not provided with a command that requires it or the session key is no longer valid. The client should reissue an AUTH command.
NOTE: A frontend shall expect 501 and 502 messages to be returned on ANY command.
NOTE: Anidb usernames are always lowercase and may only contain characters (a-z) and numbers (0-9).
  • The client should silently convert all entered usernames to lowercase before sending them to the API.
  • The client should send the apiversion of the AnimeDB API version it supports as value of the protover parameter.
  • The client MAY NOT send anything but the version of the API Specs the author used to write the client! (as it is stated at the top of this file @ "Version number used for protover parameter")
The API will compare that value to it's own version of the API and if the version of the client is older the API will decide wheter the changes were significant enough to deny the old client access to the DB.
  • The clientname shall be a lowercase string containing only the chars a-z of 4-16 chars length which identifies the client. (i.e. mykickassclient)
  • The clientversion shall be a number starting with 1, increased on every change in the client.
clientname and clientversion might be used by the API to distinguish between different clients and client versions if that should ever become nessecary.
IMPORTANT:
  • DO NOT use the clientname of another existing client.
  • ALWAYS increase the clientversion number if you release a new client version.
  • A Login and its assigned session_key is valid until the virtual UDP connection times out or until a LOGOUT command is issued.
  • The virtual UDP connection times out if no data was recieved from the client for 35 minutes.
  • A client should issue a UPTIME command once every 30 minutes to keep the connection alive should that be required.
  • If the client does not use any of the notification/push features of the API it should NOT keep the connection alive, furthermore it should explicitly terminate the connection by issueing a LOGOUT command once it finished it's work.
  • If it is very likely that another command will be issued shortly (within the next 20 minutes) a client may keep the current connection open, until it times out on it's own, by not sending a LOGOUT command.
  • The client shall notify the user if it recieved a 201 message at login.
This means a new version of the client is available, however the old version is still supported otherwise a client banned message would have been returned.
  • The user should get a popup message on 503 and 504 messages telling him to update his client software.
(NOTE: 504 means that this version of the client is banned, not the user!)
  • The 'nat' option makes the client able to detect whether it is behind a nat router or not. When the client is behind a nat router it should keep the "connection" alive with the PING command.
IMPORTANT: Make sure your client handels ALL possible AUTH return codes before giving out any versions!
  • When enc=x is defined the server will change the encoding used to x.
    • If the encoding is supported it will change right away (including the response) and be reset on logout/timeout.
    • If not supported then the argument will be silently ignored. Use ENCODING to test what works.
    • Supported encodings are these.
  • comp=1 means that the client supports compression (DEFLATE).
    • The server will compress (instead of truncating) the datagrams when needed if this option is enabled.
    • The first two bytes of compressed datagrams will always be set to zero. (So tags should never start with that.)
  • Default MTU is 1400. Minimum allowed is 400, maximum 1400, due PPPoE.

LOGOUT: Logout

Command String:

  • LOGOUT

Possible Replies:

  • 203 LOGGED OUT
  • 403 NOT LOGGED IN

Info:

  • This command only works if you are already logged in.
  • A logout should ALWAYS be issued if the client is currently logged in and is either exiting or not expecting to send/receive any anidb api packets for the next >= 30 minutes.

ENCRYPT: Start Encrypted Session

Will cause all future messages from the server, except the first (the reply to the ENCRYPT command itself), to be encrypted (128 bit AES). The client will also have to encrypt all future requests sent to the server. All non-encrypted messages will be discarded by the server. The encryption key is the MD5 hash of a special API Password (defined in the users profile) concatenated with the salt string as given in the reply to the ENCRYPT message. A normal AUTH message is still necessary to authenticate and should follow the ENCRYPT command once the API has acknowledged the encryption.

Command String:

  • ENCRYPT user={str name}&type={int2 type}

Possible Replies:

  • 209 {str salt} ENCRYPTION ENABLED
  • 309 API PASSWORD NOT DEFINED
  • 509 NO SUCH ENCRYPTION TYPE
  • 394 NO SUCH USER

Info:

  • user is the user name.
  • type is the type of encryption; 1 => 128 bit AES (only one defined).
  • API Password is the one defined in the profile settings page.
  • It is not possible to disable the encryption once enabled while staying logged in.
    • A logout (the logout message needs to be correctly encrypted) or timeout will disable the encryption.
  • In order to minimize server load, encryption should be disabled by default and should have to be enabled manually by the user in the configuration options.
  • The encryption key is md5(api_password_of_user+salt).
  • Padding of the message needs to be done according to the PKCS5Padding scheme.


Notify Commands

Introduction

Broadly speaking, notifications provide an indication to the client that some event has occurred within the AniDB database.

There are three types:

  • New file notification. (Only anime type supported.)
  • New private message notification.
  • New buddy event notification.

Note that, while a user can subscribe to multiple 'new file' events (see notifications), at present, the UDP API only supports notifications of new files by anime. New files by group, or new files by producer, are NOT presently supported. Just the same, keeping in mind that the API is designed to potentially support such notifications in the future will help in understanding why some of the commands are structured the way they are.

The word "notification" is also used a bit inconsistently in this document. An AniDB notification is originally a "new file notification". It might be more correct to use the term "event" for the original "happening" and then "notification" as the means to notify the user (client). New-file, new-message, buddy-* and going-down are all events that results in notifications. Only the first two type of events are persistent, though, meaning they exist and remain in the same state until some user action affects them.

Getting Notifications

Clients that wish to receive notifications have two routes available to them. They are by no means mutually exclusive and selecting one does not imply a client is unable to use commands from another.

Method One: Polling

With this method, the client contacts the server at some interval (no more than once every 20 minutes) to see if there are new file notifications waiting. If there are, the client can the get further details of the files in question. This is analogous to checking an email server every half hour to see if new email has arrived.

Its principal advantage is that it is easy to design and code. Blocking sockets are sufficient as the client can expect the reply received to correspond with the command sent.

The disadvantage of this approach is that it introduces a delay and some uncertainty in receiving notifications. If, for example, the user clears the notification on the website before the client collects it, the client will not learn of the new file. Similarly, if the user does not dismiss notifications via the site, the client will have an increasing amount of stale data to work though. Finally, notifications cleared by the client also clears them from the website, so users will need to be made aware of what is going on.

A polling HOWTO:

  • Use NOTIFY (no more than once every 20 minutes) to get the number of pending notifications
  • IF there are new notifications pending, use NOTIFYLIST to get a list of notification types and associated IDs.
  • Use NOTIFYGET to receive a notification, suppling the ID provided by NOTIFYLIST
  • Use NOTIFYACK to acknowledge a notification, suppling the ID provided by NOTIFYLIST (if desired)


NOTE The ID supplied by NOTIFYLIST will be the ID of the affected notification type. Since, at present, only the anime type is supported, this value is always an aid. In the future, it may represent a group or producer ID. In these cases, the str type value will indicate what entity the ID represents.

Method Two: Server PUSH

With this method, the server takes the active role in advising the client that a new file has arrived. The client must register with the server to receive these advisements, and will be responsible for keeping the login session from timing out, and any NAT router ports open. The UDP packet is sent to the ip and port from which the AUTH command was recieved.

This method compensates for the disadvantages of the polling method, but is more difficult to code. Blocking sockets are no longer an option, nor can a client make any assumptions that an incoming packet will necessarily be a reply to the last command sent. The tag option may be helpful here.

A PUSH HOWTO:

  • PUSH to register your client session.
  • Listen for 271-274 NOTIFICATIONs (not 290).
  • Use PUSHACK to to acknowledge the notification using the nid supplied with NOTIFICATION
  • Use NOTIFYGET to receive a notification, suppling the relid provided by NOTIFICATION (NOT the packet ID)
  • Use NOTIFYACK to acknowledge a notification, suppling the relid provided by NOTIFICATION (if desired)
  • Use UPTIME (with an interval between 30 and 35 minutes) to keep login session valid


It is probably a good idea to use tags to separate NOTIFICATIONs from the other communication. NOTIFICATIONs will never have tags.


PUSH: UDP Notification Registration

Register your client as an observer for anidb notification events for the current user. If you are registered for one or more event types the anidb server will send an UDP packet (format see below) on each change which affects the current user.

Command String:

  • PUSH notify={boolean on_new_file}&msg={boolean on_new_private_message}[&buddy={boolean on_buddy_event}]

Possible Replies:

  • 270 NOTIFICATION ENABLED

OR (if both values are 0)

  • 370 NOTIFICATION DISABLED

Info:

  • A client which has registered to recieve UDP notification packets must:
    • Issue a PUSHACK command for each notification received with notify_packet_id provided in the notification packet.
    • Use PING to keep the connection alive (< 30 min).
    • Use UPTIME to ensure that the session is OK (>= 30 min).
  • Every notification generated is resent 3 times unless acknowleged. After that the client is logged out.

Notification Packet Format

New File Notify:

 271 {int4 notify_packet_id} NOTIFICATION
 {int4 relid}|{int4 date}|{int4 count}|{str relname}|{int2 reltype}|{int2 priority}
  • relid is the id of the related entry (anime, group)
  • date is the time of the event (in seconds since 1.1.1970)
  • count is the number of events pending for type
  • relname is the name of the related entry
  • reltype is: 1 = anime, 2 = group, 3 = producer
  • priority is: 0 = low, 1 = medium, 2 = high
NOTE Group (and producer) related file notifications are not implemented yet.

New Private Message Notify:

 272 {int4 notify_packet_id} NOTIFICATION
 {int2 type}|{int4 date}|{int4 sent_by_uid}|{str sent_by_name}|{str subject}|{str body}|{int mid}
  • type is the type of the message (0=normal msg, 1=annonymous, 2=system msg, 3=mod msg)
  • date is the time the message was sent (in seconds since 1.1.1970)
  • senderuid/sendername are the user id and username of the sender
  • subject is the message subject
  • body is message body (can be truncated)
  • mid is message id and can be used with NOTIFYACK

Buddy Event Notify:

 273 {int4 notify_packet_id} NOTIFICATION
 {int4 buddy uid}|{int2 event type}
  • Possible event types:
    • 0 => LOGIN
    • 1 => LOGOUT
    • 2 => ACCEPTED
    • 3 => ADDED

Going Down Event Notify:

 274 {int4 notify_packet_id} NOTIFICATION
 {int4 time offline}|{int4 comment}
  • Clients with any notification on will receive the GOINGDOWN message before the API goes offline.
  • Time offline is the time in minutes the API will be down, 0 if indefinite (client can direct user to the anidb site for status updates).
  • The comment is a short explanation for the downtime.
  • Only one datagram will be sent, and the server will not listen for replies.

PUSHACK: UDP Notification Acknowledge

Used to acknowledge notification packets (271-274). A client must be prepared to issue this command before using PUSH.

Command String:

  • PUSHACK nid={int4 notify_packet_id}

Possible Replies:

  • 280 PUSHACK CONFIRMED
  • 380 NO SUCH PACKET PENDING

Info:

  • See: PUSH

NOTIFY: Notifications

Get number of pending notifications (and number of online buddies).

Command String:

  • NOTIFY [buddy=1]

Possible Replies:

  • 290 NOTIFICATION
{int4 pending_file_notifications}|{int4 number_of_unread_messages}

when buddy=1

  • 290 NOTIFICATION
{int4 pending_file_notifications}|{int4 number_of_unread_messages}|{int4 number_of_online_buddies}

Info:

  • If the client did send a NOTIFY within the last 35 minutes and it was confirmed by AniDB then recieving a 501 LOGIN FIRST message for the next NOTIFY command shows that AniDB logged the client out because it did not respond to a PUSH Notification packet.
  • There is no command to retrieve missed PUSH Notifications.
NOTE This command MUST NOT be issued more than once every 20 minutes.

NOTIFYLIST: List Notification/Message IDs

List id of all pending (not acknowledged) new private message and new file notifications. Buddy events are not acknowledgeable.

Command String:

  • NOTIFYLIST

Possible Replies:

  • 291 NOTIFYLIST
{str type}|{int4 id}
{str type}|{int4 id}
...

Info:

  • type is:
M for message entries
N for notification entries
  • id is the identifier for the notification/message as required by NOTIFYGET. For messages it is the actual message id, for notifications it is the id of the related type; anime, group or producer. Since only file notifications related to anime is implemented atm, it is the anime id (aid).
  • NOTIFYLIST returns one line per entry, if no entries are available only the first line of the reply is returned.
NOTE This command MUST NOT be issued regulary but should only be triggered by either a push message recieved by the client or a reply to a NOTIFY command which tells you that there are messages/notifications waiting.

NOTIFYGET: Get Notification/Message

  • 393 NO SUCH ENTRY

Info:

  • type is:
M for message entries
N for notification entries
  • id is the identifier for the notification/message as given by NOTIFYLIST (or relid from 271 NOTIFICATION and mid from 272 NOTIFICATION)
  • for message entries (M):

  • 322 MULTIPLE FILES FOUND
{int4 fid 0}|{int4 fid 1}|...|{int4 fid n}
  • 320 NO SUCH FILE

Info:

  • fid, aid, eid, gid are the unique ids for the file, anime, ep, group entries at anidb.
You can use those to create links to the corresponding pages at anidb.
  • anidbfilename is the anidb filename for the file.
However this name does not contain all the extra information of the filenames on AniDB and might be composed slightly different.
  • fmask and amask are hexidecimal strings where each bit corresponds to a data field related to the specified file (see below). The data list received is sorted in the same order as the tables (and fmask before amask). There is no provision to retrieve all fields. Further, requesting a 'unusued' or 'reserved' bit will return an "illegal input" error.
  • Only the first matching file is returned when aname, gname and epno is used.

State:

bit / int value 	meaning
1 / 1 		FILE_CRCOK: file matched official crc (displayed with green background in anidb)
2 / 2 		FILE_CRCERR: file DID NOT match official crc (displayed with red background in anidb)
3 / 4 		FILE_ISV2: file is version 2
4 / 8 		FILE_ISV3: file is version 3
5 / 16 		FILE_ISV4: file is version 4
6 / 32 		FILE_ISV5: file is version 5
7 / 64 		FILE_UNC: file is uncensored
8 / 128		FILE_CEN: file is censored

examples:

  • 321 NO SUCH ENTRY

Info:

  • The state field provides information about the location and sharing state of a file in mylist.
  • If files are added after hashing, a client should specify the state as 1 (on hdd) (if the user doesn't explicitly select something else).
  • eps is a list of episodes, e.g. "1-12,14-16,T1"

States:

 0 - unknown - state is unknown or the user doesn't want to provide this information
 1 - on hdd - the file is stored on hdd (but is not shared)
 2 - on cd - the file is stored on cd
 3 - deleted - the file has been deleted or is not available for other reasons (i.e. reencoded)

Filestates: (for normal files, ie. not generic)

 0   => normal/original
 1   => corrupted version/invalid crc
 2   => self edited
 10  => self ripped
 11  => on dvd
 12  => on vhs
 13  => on tv
