GNU Libidn 0.2.3 alpha released

[Simon Josefsson]

GNU Libidn is an implementation of the Stringprep, Punycode and IDNA
specifications defined by the IETF Internationalized Domain Names
(IDN) working group, used for internationalized domain names.  The
package is available under the GNU Lesser General Public License.

The library contains a generic Stringprep implementation that does
Unicode 3.2 NFKC normalization, mapping and prohibitation of
characters, and bidirectional character handling.  Profiles for iSCSI,
Kerberos 5, Nameprep, SASL and XMPP are included.  Punycode and ASCII
Compatible Encoding (ACE) via IDNA are supported.

The Stringprep API consists of two main functions, one for converting
data from the system's native representation into UTF-8, and one
function to perform the Stringprep processing.  Adding a new
Stringprep profile for your application within the API is
straightforward.  The Punycode API consists of one encoding function
and one decoding function.  The IDNA API consists of the ToASCII and
ToUnicode functions, as well as an high-level interface for converting
entire domain names to and from the ACE encoded form.

The library is used by, e.g., GNU SASL and Shishi to process user
names and passwords.  Libidn can be built into GNU Libc to enable a
new system-wide getaddrinfo flag for IDN processing.

Libidn is developed for the GNU/Linux system, but runs on over 20
platforms including most major Unix platforms and Windows, and many
kind of devices including iPAQ handhelds and S/390 mainframes.
Libidn is written in C and (parts of) the API is accessible from C,
C++, Emacs Lisp, Python and Java.

The project page of the library is available at:

Noteworthy changes since version 0.2.0 (last version announced here):

* Version 0.2.3 (released 2003-08-26)

** Example 4 was the same as example 3, now changed to demo ToUnicode.

** Documentation improvements.

** Prototype cleanups.
The proper enum types (Stringprep_rc, Idna_rc, etc) are now used in
several places where plain int where used before.  String lengths are
handled by (s)size_t instead of int.

** API and ABI is backwards compatible with the previous version.

* Version 0.2.2 (released 2003-08-13)

** Fixed problem with strings longer than 4GB in punycode functions.
The punycode code cannot handle strings longer than 4GB.  The code now
return PUNYCODE_BAD_INPUT on too long input, instead of failing in an
unknown way.

** The "idn --idna-to-unicode" command now output locale encoded strings.

** Build fixes, bug fixes.

** API and ABI is backwards compatible with the previous version.

* Version 0.2.1 (released 2003-07-04)

** Don't reject zero-length trailing labels as in, e.g., "www.example.org.".
The IDNA RFC is not clear on this topic, zero-length labels in general
are forbidden by the ToASCII algorithm in section 4.1 step 8, but the
terminology section define, inside a parenthesis, that the zero-length
root label is in fact not considered a label at all in IDNA.

** Bug fixes.

** API and ABI is backwards compatible with the previous version.

2003-08-13  Simon Josefsson <address@hidden>

        * punycode.c: Revert to RFC code: use punycode_uint and enum
        punycode_status.  However, we do continue to use size_t to promote
        use of sizeof() by application writers.  We return
        punycode_bad_input if a size_t value exceeds the largest
        punycode_uint, since the code presumably cannot handle that.  If
        size_t is smaller than punycode_uint, it seems unlikely that an
        application could be able to pass a string that is longer than
        SIZE_MAX anyway, but should it happen the worst that occur is that
        the punycode code will only see the beginning of the string, which
        isn't unreasonable on a platform with a small SIZE_MAX.
