bypassing the cache response stage and uniquifying mesh states. Four EDNS option lists were added to module_qstate (module_qstate.edns_opts_*) to store EDNS options from/to front/back side. - Added two flags to module_qstate (no_cache_lookup, no_cache_store) that control the modules' cache interactions. - Added code for registering inplace callback functions. The registered functions can be called just before replying with local data or Chaos, replying from cache, replying with SERVFAIL, replying with a resolved query, sending a query to a nameserver. The functions can inspect the available data and maybe change response/query related data (i.e. append EDNS options). - Updated Python module for the above. - Updated Python documentation. git-svn-id: file:///svn/unbound/trunk@3947 be551aaa-1e26-0410-a405-d3ace91eadb9

=====================================
|
|
|
|
Unlike the libUnbound, pyUnbound is able to handle IDN queries.
|
|
|
|
Automatic IDN DNAME conversion
|
|
-------------------------------
|
|
|
|
If we use unicode string in :meth:`unbound.ub_ctx.resolve` method,
|
|
the IDN DNAME conversion (if it is necessary) is performed on background.

IDN converted attributes
|
|
------------------------
|
|
|
|
The :class:`unbound.ub_data` class contains attributes suffix which converts
|
|
the dname to UTF string. These attributes have the ``_idn`` suffix.
|
|
|
|
Apart from this aproach, two conversion functions exist
|
|
(:func:`unbound.idn2dname` and :func:`unbound.dname2idn`).
