If the hub does not directly support the client's locale, it should attempt to fall back to the same language group (e.g. hub supports en-US but not en-AU, so falls back to en-US), and if this is not available, then fall back to the hub's own locale.

 === BLOM- Bloom filter
 
 Bloom filters allow the hub to filter certain searches using bitmap that represents the hashes of the files in the users share. BLOM is an extension that allows hub software to create a map (bloom filter) of the shared files on the hub, but with minimal effort, e.g. the hub doesn't keep a list of files, but a filter that never produces false negatives but only possible false positives. This can potentially save bandwidth and effort on the client side. When the user updates the share, the client must send an INF containing the flag SF. The hub may at any time request that the client sends an updated version of its bloom filter by sending a GET command to the client. The client will then respond using SND and send the bloom filter binary data.

 Once the hub has received the bloom filter bit array, for each search command it processes, if it contains a hash search term, it can skip broadcasting the search to a particular client if at least one of the k bits in that clients bit array is "0", calculating positions as the client does when setting bits to "1". The hub has to evaluate the filter for each client that it has a bloom filter for, for each search. 
 
 ==== Probability calculations 
-p = (1 - (1 - 1 / m)\^(k * n))\^k, thus p becomes smaller as m grows and larger as n grows. Larger m means more bits to transfer but also fewer false positives. The optimum value for k given m and n is (m / n) * ln 2. The largest k supported by a hash of a certain size is b / h, so if the hub wants the smallest p possible, it should choose the smallest possible h which gives the largest k, and then calculate m = k * n/ln 2, checking that the resulting m < 2\^h. 2^h should much be larger than m (at least 3-4 times), because of how the modulo operator works. Also, with m grows the required bandwidth to transfer the bloom filter, so the hub may wish to cap m. In that case, it should still choose k according to m / n * ln 2, but send an h as big as possible to alleviate biasing problems.

 For TTH roots, b is 192 and a reasonable value for h is 24, giving a maximum k = 8 which means that m = 8 * n / ln 2 ≈ 11.5 * n. The required bandwidth then becomes 11.5 * n / 8 bytes, so approximately 1.44 bytes per file in the users share. For 20000 files, m should then be 230016 (taking into account the modulo 64 requirement), giving a p = 0.004, in other words ~99.6% of all searches that don't match a users share would not be sent, saving valuable upload bandwidth for the hub. The client calculates i valid positions, if x is an array of bytes containing the hash of the file, on a little-endian machine, by doing pos = x[0+i*h/8] | (x[1+i*h/8] << 8) | (x[2+i*h/8] << 16) for i = [0;k). This is of course a special case where h % 8 = 0, the actual algorithm has to take into consideration values for h where the integer crosses byte boundaries.

+
+== Version history
+The latest draft of the next version of this document as well as intermediate

+This version corresponds to $Revision: 1 $.

+=== Version 1.0.0
+* Initialize release
+
+== General recommentations
+
+Message length
+Messages can be constructed to be long or short with varying complexity. All messages that contain a positional parameter can also contain additional named parameters. This mean that implementations must be able to read enough data to accuratley be aware of additional data. This also means that it may be in the implementations' interest to stop processing after an excessive amount of data, but implementations should strive to be as resiliant as possible. Certain messages that require parsing of specific parts, their context and content (e.g. regular expressions) may very well be short but nontheless pose a security issue if not dealt with appropriately.
+
+== STA recommendations
+Clients should display text messages appropriately depending on context, severity and error code. It is recommended to display the error message regardless of the error code. Hubs must not depend on where clients display error codes.
+
+While STA messages require a severity to accompany the error code, the severity may not be of importance to some error codes or are simply implied by the actual error code. However, it is important that the severity is sent as appropriate and is accurate. STA messages with 0 (success) for severity can usually be regarded by implementations that the information require little or no counter-action.
+The following list include error codes that make no or little sense in one or many severities, and a description why they are best used in one or only some severities. The descriptive text for the error codes can be seen in the STA specification, but may be re-stated as part of the description why they can have severity restriction(s).
+
+11 | If the hub is full, it makes little sense in keeping the client in some "connected" state. The recommended severity is to use 2 (fatal) to force the client to reconnect at a later time.
+12 | Similar to error code 11.

 Once the hub has received the bloom filter bit array, for each search command it processes, if it contains a hash search term, it can skip broadcasting the search to a particular client if at least one of the k bits in that clients bit array is "0", calculating positions as the client does when setting bits to "1".

The largest k supported by a hash of a certain size is b / h, so if the hub wants the smallest p possible, it should choose the smallest possible h which gives the largest k, and then calculate m = k * n/ln 2, checking that the resulting m < 2^h. 2^h should much be larger than m (at least 3-4 times), because of how the modulo operator works. Also, with m grows the required bandwidth to transfer the bloom filter, so the hub may wish to cap m. In that case, it should still choose k according to m / n * ln 2, but send an h as big as possible to alleviate biasing problems.

+=== BLOM
+
+Bloom filters allow the hub to filter certain searches using bitmap that represents the hashes of the files in the users share. BLOM is an extension that allows hub software to create a map (bloom filter) of the shared files on the hub, but with minimal effort, e.g. the hub doesn't keep a list of files, but a filter that never produces false negatives but only possible false positives. This can potentially save bandwidth and effort on the client side. When the user updates the share, the client must send an INF containing the flag SF. The hub may at any time request that the client sends an updated version of its bloom filter by sending a GET command to the client. The client will then respond using SND and send the bloom filter binary data.

+

+|=====
+|BK |Specify 'k'.
+|BH |Specify 'h'.
+|=====
+
+==== Algorithm 
+The client constructs the bloom filter by creating a bit array of m bits set to 0 (zero). For each file it then sets to "1" k positions constructed from the file hash. Seeing the file hash as a stream of bits (starting from the lowest bit of the first byte, ending at the highest bit of the last byte), the client should use h bits starting at the first bit of the first byte to create an integer and apply modulo m to get the position in the bit array, then redo the process k times advancing the starting position by h each time. 
+
+Once the hub has received the bloom filter bit array, for each search command it processes, if it contains a hash search term, it can skip broadcasting the search to a particular client if at least one of the k bits in that clients bit array is "0", calculating positions as the client does when setting bits to "1". The hub has to evaluate the filter for each client that it has a bloom filter for, for each search. 
+
+==== Probability calculations 
+p = (1 - (1 - 1 / m)^(k * n))^k, thus p becomes smaller as m grows and larger as n grows. Larger m means more bits to transfer but also fewer false positives. The optimum value for k given m and n is (m / n) * ln 2. The largest k supported by a hash of a certain size is b / h, so if the hub wants the smallest p possible, it should choose the smallest possible h which gives the largest k, and then calculate m = k * n/ln 2, checking that the resulting m < 2^h. 2^h should much be larger than m (at least 3-4 times), because of how the modulo operator works. Also, with m grows the required bandwidth to transfer the bloom filter, so the hub may wish to cap m. In that case, it should still choose k according to m / n * ln 2, but send an h as big as possible to alleviate biasing problems. 
+
+==== Sample implementations
+===== Tiger
+For TTH roots, b is 192 and a reasonable value for h is 24, giving a maximum k = 8 which means that m = 8 * n / ln 2 ≈ 11.5 * n. The required bandwidth then becomes 11.5 * n / 8 bytes, so approximately 1.44 bytes per file in the users share. For 20000 files, m should then be 230016 (taking into account the modulo 64 requirement), giving a p = 0.004, in other words ~99.6% of all searches that don't match a users share would not be sent, saving valuable upload bandwidth for the hub. The client calculates i valid positions, if x is an array of bytes containing the hash of the file, on a little-endian machine, by doing pos = x[0+i*h/8] | (x[1+i*h/8] << 8) | (x[2+i*h/8] << 16) for i = [0;k). This is of course a special case where h % 8 = 0, the actual algorithm has to take into consideration values for h where the integer crosses byte boundaries.

-= ADC Extensions
-Jacek Sieka <arn...@gm...>
-1.0, May 2008
-
-== Abstract
-These are the official extensions to ADC. This document is based on the
-information contained in the ADC wiki - spefications from there are moved here
-when they are mature and stable enough.
-
-== Version history
-The latest draft of the next version of this document as well as intermediate
-and older versions can be downloaded from
-$URL$.
-
-This version correspods to $Revision$.
-
-=== Version 1.0
-* Initial release created from original ADC 1.0 text
-* Added PING extension
-
-== Extensions
-
-=== TIGR - Tiger tree hash support
-
-==== General
-
-This extension adds Tiger tree hash support to the base protocol. It is
-intended to be used both for identifying files and for purposes such as CID
-generation and password negotiation
-
-==== TIGR for shared files
-All files shared by TIGR supporting clients must have been hashed using Merkle
-Hash trees, as defined by
-http://www.open-content.net/specs/draft-jchapweske-thex-02.html.  The Tiger
-algorithm, as specified by http://www.cs.technion.ac.il/~biham/Reports/Tiger/,
-functions as the hash algorithm. A base segment size of 1024 bytes must be
-used when generating the tree, but clients may then discard parts of the tree
-as long as at least 7 levels are kept or a block granularity of 64 KiB is
-achieved.
-
-Generally, the root of the tree (TTH) serves to identify a file uniquely.
-Searches use it and it must be present in the file list. Further, the root of
-the file list must also be available and discoverable via GFI. A client may
-also request the rest of the tree using the normal client-client transfer
-procedure. The root must be encoded using base32 encoding when converted to
-text.
-
-In the file list, each File element carries an additional attribute "TTH"
-containing the base32-encoded value of the Tiger tree root.
-
-In the GET/GFI type, the full tree may be accessed using the "tthl" type.
-
-"tthl" transfers send the largest set of leaves available) as a binary stream
-of leaf data, right-to-left, with no spacing in between them.  <start_pos>
-must be set to 0 and <bytes> to -1 when requesting the data.  <bytes> must
-contain the total binary size of the leaf stream in SND; by dividing this
-length by the individual hash length, the number of leaves, and thus the leaf
-level, can be deducted. The received leaves can then be used to reconstruct
-the entire tree, and the resulting root must match the root of the file (this
-verifies the integrity of the tree itself). Identifier must be a TTH root
-value from the "TTH/" root.
-
-In the GET/GFI namespace, files are identified by 
-"TTH/<base32-encoded tree root>".
-
-In SCH and GFI, the following attributes are added:
-
-[separator="|"]
-``_
-TR | Tiger tree Hash root, encoded with base32.
-TD | Tree depth, index of the highest level of tree data available, root-only = 0, first level (2 leaves) = 1, second level = 2, etc...
-___
-
-=== BZIP – File list compressed with bzip2
-This extension adds a special file "files.xml.bz2" in the unnamed root of the
-share which contains "files.xml" compressed with bzip2 1.0.3+ (www.bzip.org).
-
-=== ZLIB - Compressed communication
-There are two variants of zlib support, FULL and GET, and only one should be
-used on a each communications channel set up.
-
-==== ZLIB-FULL
-If, during SUP negotiation, a peer sends "ZLIF" in its support string, it must
-accept two additional commands, ZON and ZOF. Upon reception of ZON the peer
-must start decompressing the incoming stream of data with zlib before
-interpreting it, and stop doing so after ZOF is received (in the compressed
-stream). The compressing end must partially flush the zlib buffer after each
-chunk of data to allow for decompression by the peer.
-
-==== ZLIB-GET
-The alternative is to send "ZLIG" to indicate that zlib is supported for
-binary transfers using the GET command, but not otherwise. A flag "ZL1" is
-added to the to the SND command to indicate that the data will come
-compressed, and the client receiving requests it by adding the same flag to
-GET (the sending client may ignore a request for a compressed transfer, but
-may also use it even when not requested by the receiver). The <bytes>
-parameter of the GET and SND commands is to be interpreted as the number of
-uncompressed bytes to be transferred.
-
-=== PING - Pinger extension
-Added 2008-03-14, based on ADC 1.0
-
-This extension can be supported by both clients and hubs, and when present, if hub
-supports it, it must send additional information to the client ( otherwise normal
-base client).
-
-It's purpose is to send to hublist pingers additional information about the hub
- that otherwise it would be impossible to get as a normal user (eg. minimum share, 
- maximum user count, etc).
-
-==== INF
-
-Contexts : F
-
-When the client supporting the PING extension connects, the hub must send its
-normal INF along with the following added fields ( none mandatory, if not present,
-it means hub has no restrictions in that matter, or non existent):
-
-[separator="|"]
-```_
-Code | Type    | Description
-___
-HH   | string  | Hub Host address ( DNS or IP )
-WS   | url     | Hub Website
-NE   | string  | Hub Network
-OW   | string  | Hub Owner name
-UC   | integer | Current User count
-SS   | integer | Total share size
-SF   | integer | Total files shared
-MS   | integer | Minimum share required to enter hub ( bytes )
-XS   | integer | Maximum share for entering hub ( bytes )
-ML   | integer | Minimum slots required to enter hub
-XL   | integer | Maximum slots for entering hub
-MU   | integer | Minimum hubs connected where clients can be users
-MR   | integer | Minimum hubs connected where client can be registered
-MO   | integer | Minimum hubs connected where client can be operators
-XU   | integer | Maximum hubs connected where clients can be users
-XR   | integer | Maximum hubs connected where client can be registered
-XO   | integer | Maximum hubs connected where client can be operators
-MC   | integer | Maximum possible clients ( users ) who can connect
-UP   | integer | Hub uptime (seconds)
-NI   | string  | Hub name (from BASE)
-DE   | string  | Hub description (from BASE)
-VE   | string  | Hub software version (from BASE)
-___
-
-The hub must continue to send the user list as for a normal user (move to
-NORMAL state). The pinger may decide to go through or disconnect (eg. if it
-doesn't require additional information about the users).

- - (pinger may disconnect)
- -..
-----
-
-==== Hub - Hublist communication
-
-The same extension goes for hub- hublist communication. This way, the hub
-takes the role of the client and the hublist of the server.
-
-The hublist may send INF about itself with NI field which would become hublist
-name and WS hublist web address.
-
