NEWS
====
+---------------------------------------------------
+0.4.0 (to be announced) "simultaneous independence"
+---------------------------------------------------
+
+Two significant changes which require the new version number: The
+improved authentication dialog and the fact that the database code
+has been moved to a library, libosl. To use the new version, you have
+to generate new RSA keys, see INSTALL for details. A shell script is
+provided for conversion of the 0.3 database to the new 0.4 format.
+
+ - stronger crypto for client authentication
+ - the database code has been moved to a library
+ - improved status item handling
+ - cleanup of the build system
+ - The "-V" option now also prints the git version
+ - the new parser-friendly listing mode for the ls and stat commands
+ - mandatory rc4 encryption
+ - major audio format handler cleanups
+ - (id3,...) tags are no longer stored as a combined string in the database
+ - new mood methods: artist_matches, title_matches, comment_matches,
+ album_matches, year_maches, year.
+
--------------------------------------------
0.3.5 (2009-09-21) "symplectic separability"
--------------------------------------------
a set of *mood lines* containing expressions in terms of attributes
and other data contained in the database.
-A mood defines a subset of audio files called the *admissible audio
-files* for that mood. At any time, at most one mood can be *active*
-which means that para_server is going to select only files from that
-subset of admissible files.
+A mood defines a subset of audio files called the *admissible audio files*
+for that mood. At any time, at most one mood can be *active* which
+means that para_server is going to select only files from that subset
+of admissible files.
So in order to create a mood definition one has to write a set of
mood lines. Mood lines come in three flavours: Accept lines, deny
Takes no arguments and matches an audio file if and only if no
attributes are set.
- played_rarely
-
-Takes no arguments and matches all audio files where the number of
-times this audio file was selected is below the average.
-
- is_set attribute_name
+ is_set <attribute_name>
Takes the name of an attribute and matches iff that attribute is set.
- path_matches pattern
+ path_matches <pattern>
Takes a filename pattern and matches iff the path of the audio file
matches the pattern.
+ artist_matches <pattern>
+ album_matches <pattern>
+ title_matches <pattern>
+ comment_matches <pattern>
+
+Takes an extended regular expression and matches iff the text of the
+corresponding tag of the audio file matches the pattern. If the tag
+is not set, the empty string is matched against the pattern.
+
+ year ~ <num>
+ bitrate ~ <num>
+ frequency ~ <num>
+ channels ~ <num>
+ num_played ~ <num>
+
+Takes a comparator ~ of the set {<, =, <=, >, >=, !=} and a number
+<num>. Matches an audio file iff the condition <val> ~ <num> is
+satisfied where val is the corresponding value of the audio file
+(value of the year tag, bitrate in kbit/s, frequency in Hz, channel
+count, play count).
+
+The year tag is special as its value is undefined if the audio file
+has no year tag or the content of the year tag is not a number. Such
+audio files never match. Another difference is the special treatment
+if the year tag is a two-digit number. In this case either 1900 or
+2000 are added to the tag value depending on whether the number is
+greater than 2000 plus the current year.
+
----------
Mood usage
In any case you need
+ - libosl: If you are compiling from git the osl sources should
+ have been cloned automatically. It is also available for
+ download from http://git.tuebingen.mpg.de/osl. Or run the
+ command "git clone git://git.tuebingen.mpg.de/osl"
- gcc, the gnu compiler collection (shipped with distro): gcc-3.3
or newer is required.
- gnu make (shipped with disto, might be called gmake)

-## Script to convert the database of paraslash 0.2.x to version 0.3.x.
-##
-## Assumptions:
-## - para_server 0.2.x is running and the mysql selector is active
-## - para_server 0.3.x is running on another port
-## - The database of paraslash 0.3.x has been initialized (i.e.
-## para_client init has successfully been executed)
-## - All audio files in the mysql database of paraslash 0.2.x. have
-## already been added to the 0.3.x database (execute para_client add
-## /my/audio/file/dir to do that)
-##
-## The script converts the attribute table, the set attributes for each audio
-## file, the image table and all image ids, and finally the lastplayed and the
-## numplayed data.
-##
-## However, it does not convert the paraslash stream definitions from 0.2.x to
-## the moods of 0.3.x. You'll have to do this by hand.
