This file describes the external changes and important bug fixes between different libcddb releases. These changes might impact the programs that use this library. It does not describe every single change made to the code tree. An overview of the CVS changes can be found in the Changelog file. CHANGES 1.2.1 -> 1.2.2 * [BUGFIX] Correctly specify the character set (UTF-8) when submitting data to a server. CHANGES 1.2.0 -> 1.2.1 * [NEW] It is now possible to fine tune the text search by specifying which fields and categories to consider. * [BUGFIX] Fixed cddb_sites function returning random values due to uninitialized value. * [UPDATE] The value of the LIBCDDB_VERSION_NUM defined variable is now 121. CHANGES 1.1.0 -> 1.2.0 * [NEW] Support for searching the FreeDB database using a text string has been added. This feature has a similar API as the query command but uses a string instead of actual disc data. * [UPDATE] The value of the LIBCDDB_VERSION_NUM defined variable is now 120. CHANGES 1.0.2 -> 1.1.0 * [IMPORTANT] The installed header files now no longer contain any actual structure definitions. All libcddb structures are now truly opaque for the user of the library. Some of the structures have also been updated. This means that the library is not binary compatible with the previous version. It should however be possible to just recompile any software using libcddb and link it against this new library. The API is backwards compatible so no changes to the software should be necessary. * [NEW] Support for the FreeDB sites command that can be used to get a list of mirror servers. A function was also added to initialize the libcddb server connection data using one of the servers returned by this command * [NEW] A new error code was added (CDDB_ERR_INVALID) that is returned when invalid input parameters are passed to one of the library functions. * [UPDATE] The value of the LIBCDDB_VERSION_NUM defined variable is now 110. CHANGES 1.0.1 -> 1.0.2 * [NEW] Added cddb_set_http_proxy_credentials function that allows you to specify proxy user name and password in one go. It also does not store the user's credentials as cleartext in memory. * [FIX] An extra error code/message has been added to signal proxy authentication failure. CHANGES 1.0.0 -> 1.0.1 * [NEW] Added --without-cdio option to the configure script so you can manually disable CD access support for the example program. * Fixed iconv compiler warnings for Solaris and Cygwin. * Fixed regex compilation issue on MacOS X. CHANGES 0.9.6 -> 1.0.0 * [NEW] Added support for proxy authentication. * [BUGFIX] Memory leaks fixed in regular expression handling. * Iconv compilation fixes for Solaris. CHANGES 0.9.5 -> 0.9.6 * Libcddb now uses the FreeDB protocol version 6. The difference with version 5 is that now the responses from the FreeDB server are in UTF-8 format instead of ISO8859-1. So if the CD you query contains non-US-ASCII characters the results will be different in this new version of libcddb. * [NEW] It is now possible to set the character set that libcddb has to use when returning disc data (see also above). Use the cddb_set_charset function to set the user's character set. The example program, cddb_query, now also has a command-line option for specifying the character set. * [BUGFIX] FreeDB changed the specs of their CDDB file format. The results for certain discs failed to parse correctly because the libcddb parser was too strict. This should be fixed now. * [BUGFIX] When writing disc to cache, fill in category if genre is not specified. * [BUGFIX] When in CACHE_ONLY mode, do not perform network access when writing disc record. CHANGES 0.9.4 -> 0.9.5 * It is now possible to query CD entries if you only know the track length. Previous versions of libcddb needed the track offsets from the CD. Track offsets will be calculated automatically when a length is specified and the offset is missing. This is less precise than using the actual frame offsets. So whenever possible use the offsets instead. * Fixed some possible buffer overflows. The internal buffer size has also been increased from 257 to 1024 bytes. It is now also possible to change this buffer size in the cddb_cmd.h. * Updated regression tests with less strict testing. Changes in the queried CDDB entries should no longer trigger a test failure. * Improved support for Win32 platforms (thx to Rocky Bernstein). * Improved support for Mac OS X (thx to Rocky Bernstein and Derk-Jan Hartman). * It is now possible to specify the CD-ROM device to be used in the example program. CHANGES 0.9.3 -> 0.9.4 * The libcddb now installs a pkg-config(1) configuration file. * Support for tilde-expansion (~) in the local cache directory has been added. If the cache directory starts wit a tilde and the $HOME environment variable is defined, then the tilde will be replaced by the value of $HOME. * All the networking code (DNS query, connect, read, write) now supports time-outs to prevent blocking indefinitely. By default this time-out is set to ten seconds. See the cddb_conn_t structure for more information. * A logging framework was added. This framework supports different log levels and provides the possibility to install a custom log handler. (based on a similar framework in libcdio, thx Rocky) Because of this new framework, the --enable-debug configure parameter has been obsoleted by --enable-loglevel=LVL. * Added support for extended disc and track data. The parsing has been updated and getters and setters were added to the disc and track structures. * If the DTITLE field of a CDDB entry does not contain both an artist name and a disc title, libcddb assumes that they are equal. * Extra regression tests were updated and added. The test framework was also improved to skip proxy tests if the http_proxy environment variable is not defined. CHANGES 0.9.2 -> 0.9.3 * [SECURITY] The default values for the user name and the host name that is used when contacting a CDDB server have been changed to 'anonymous@localhost'. Libcddb used to take the values from the $USER and $HOSTNAME environment variables if they were present. This would reveal confidential information about a user without that person knowing it. It is still necessary to use a valid e-mail address when submitting a new or updated CDDB entry to the server. The libcddb write command will fail if the default value are still present. * Extra regression tests were added to test caching behaviour. * Some getters and setters were added for fields in the connection structure. * It is now possible to customize the program name and version that is used when contacting a CDDB server. This used to default to 'libcddb' and the version number of the library being used. Now it is possible for a developer to use the name of the program using the library. CHANGES 0.9.1 -> 0.9.2 * [BUGFIX] There was a problem with multi-line track titles. The title was being appended to title of the disc instead of to the one from the track. This should now work correctly. * [BUGFIX] The parsing state machine did not correctly detect the end of the stream if there was no extended data present. This has been fixed by putting the state machine in the STOP state when the end of the stream is encountered. * [BUGFIX] Fixed some memory leaks reported by Valgrind. * The example program now returns the libcddb error code when exiting after a failure. Proxy support has also been implemented. * The regression tests have been expanded to include scripts that test the libcddb CDDB entry parser and networking code. These networking tests need Internet connectivity and a working proxy server enabled through the http_proxy environment variable. CHANGES 0.9.0 -> 0.9.1 * A Gentoo Linux ebuild file has been added in the misc/ directory. * It is now possible to delete a disc/track title and artist name by setting it to NULL using one of the set functions for these fields. * [BUGFIX] In the previous release, when reusing a CDDB disc structure for subsequent read operations, the disc and artist name were appended to what was already present in the structure. This has been fixed by reseting those strings before setting the new values. * The example program has been improved. It now supports two extra commands. One can be used to calculate the disc ID. The other will query a CDDB server and report any matches that are found. Support was also added to retrieve the necessary disc information from a CD in the CD-ROM drive. To use this feature you will need an extra library, i.e. libcdio. Information about this library can be found at: http://savannah.nongnu.org/projects/libcdio/. * Extra getters and setters were added and the documentation of other library functions has been updated. CHANGES 0.1.6 -> 0.9.0 * The src/ directory has been removed from the distribution. But a new examples/ directory was added. Currently the example program only supports the CDDB read command. This example will be expanded in order to demonstrate every public function of the library. * Local CDDB cache semantics have been expanded. Next to the option to enable and disable caching that was already present, it is now also possible to force the use of the cache. When this functionality is enabled and an entry is not found in the local cache a CDDB_ERR_DISC_NOT_FOUND error is returned. Three functions have also been added to set the desired caching mode: - cddb_cache_enable(c) - cddb_cache_only(c) - cddb_cache_disable(c) All three functions expect a CDDB connection structure as a parameter. * Several get and set functions have been added to the API. It is my intention to have such functions for every possible field that a user is allowed to alter in the different library structures. This will prevent problems in the future if the internal structures should change. * When the length of a CD track is not set when you call the cddb_track_get_length function, it will be calculated. The calculation uses the frame offsets of the current and next track and possibly the disc length. The current implementation does not do any rounding of the calculated value to the nearest second. Therefore it is possible that the sum of the track lengths does not equal the disc length. If the length can not be calculated -1 is returned. * The network access code has been rewritten to use the network sockets directly instead of wrapping them in file descriptors. This should enable BeOS users to use the library without having to change any code. I don not have a BeOS system myself and am still waiting for a confirmation whether the changes were enough. * Support has been added for reading CDDB entries that have multi-lined fields. Support to also split certain fields into multiple lines when writing them (to the network or disc) is not yet present. The FreeDB spec states that no line should be longer than 256 characters. This limit is not yet checked. * Support to parse the year field of a CDDB entry has been added. |
