- Revision 0.1.8
- --------------
- - ObjectIdentifier codec fixed to work properly with arc 0 and arc 2 values.
- - Explicit limit on ObjectIdentifier arc value size removed.
- - Unicode initializer support added to OctetString type and derivatives.
- - New prettyPrintType() abstract method implemented to base pyasn1 types
- to facilitate encoding errors analisys.
- - The __str__() method implemented to Tag, TagSet and TagMap classes to
- ease encoding errors troubleshooting.
- easing encoding errors
- - Fix to SEQUENCE and SET types to give them their private componentTypes
- collection (which is a NamedTypes object) so that they won't collide in
- a MT execution environment.
- - Missing T61String,ISO646String character types and ObjectDescriptor useful
- type added.
- - Distribute is gone, switched to setuptools completely.
- - Missing NamedValues.__repr__() added.
- - The base.NoValue() class, that indicates uninitialized ASN.1 object,
- made public.
- - The base.NoValue() class instances now support __repr__() what makes
- possible to perform repr() on uninitialized pyasn1 types objects.
- - When comparing ASN.1 types, by-tag and/or by-constraints matching
- can now be performed with the isSuperTypeOf()/isSameTypeWith() optional
- flags.
- - Constructed types now verify their consistency by invoking
- isSameTypeWith(matchTags=True, matchConstraints=False) and
- isSuperTypeOf(matchTags=False, matchConstraints=True) for each of their
- components rather than isSuperTypeOf() as it used to be. Constriants check
- could be enforced to isSameTypeWith() with the strictConstraints=True
- constructed classes attribute.
- - Constructed types can now be initialized with new .setComponents() method
- which accepts both var-args and keyword-args. Default repr() modified to
- reflect this change.
- - NamedTypes() and NamedValues() made comparable.
- - Test coverage extended to cover pyasn1 types __repr__() function.
- - The abs(Integer()) & abs(Real()) operation now returns respective pyasn1
- type, not a Python type.
- - More Python magic methods implementations added to Integer & Real classes
- (e.g. __pos__, __neg__, __round__, __floor__, __ceil__, __trunc__)
- - The Integer.__invert__ Python magic method implemented.
- - The OctetString.__int__() and .__float__() magic methods implemented.
- - Handle the case of null writer at Debug printer.
- - BitString encoder/decoder performance improved.
- - Built-in debugging is now based on Python logging module.
- - Fix to NamedType.__repr__() to work properly.
- - Fixes to __repr__() implementation of many built-in ASN.1 types to take into
- account all of their initializers such as tagSet, subtypeSpec etc.
- - String typed float initializer to REAL type now supported.
- - Float typed mantissa initializer to REAL type for base 2 added.
- - Encoding bases 8 and 16 support for REAL type binary encoder added.
- - More strict CER/DER encoders added for GeneralizedTime and UTCTime types.
- - Asn1Item.hasValue() added to easily distinguish initalized ASN.1 objects
- from uninitialized ones (e.g. pure types).
- - Fix to REAL type binary decoder to handle different bases and scale factor.
- - Fix to TagSet.repr() to include [obsolete] baseTag information.
- - Fix to broken REAL type decoding handling.
- - Fix to BitString and OctetString decoders dealing with constructed
- encoding -- it used to be possible to embed other types in substrate.
- - Fix to end-of-octest sentinel handling:
- * require strict two-zeros sentinel encoding
- * recognize EOO sentinel only when explicitly requested by caller
- of the decoder via allowEoo=True parameter (warning: API change)
- - DER codec hardened not to tolerate indefinite length encoding/decoding.
- Revision 0.1.7
- --------------
- - License updated to vanilla BSD 2-Clause to ease package use
- (http://opensource.org/licenses/BSD-2-Clause).
- - Test suite made discoverable by unittest/unittest2 discovery feature.
- - Fix to decoder working on indefinite length substrate -- end-of-octets
- marker is now detected by both tag and value. Otherwise zero values may
- interfere with end-of-octets marker.
- - Fix to decoder to fail in cases where tagFormat indicates inappropriate
- format for the type (e.g. BOOLEAN is always PRIMITIVE, SET is always
- CONSTRUCTED and OCTET STRING is either of the two)
- - Fix to REAL type encoder to force primitive encoding form encoding.
- - Fix to CHOICE decoder to handle explicitly tagged, indefinite length
- mode encoding
- - Fix to REAL type decoder to handle negative REAL values correctly. Test
- case added.
- Revision 0.1.6
- --------------
- - The compact (valueless) way of encoding zero INTEGERs introduced in
- 0.1.5 seems to fail miserably as the world is filled with broken
- BER decoders. So we had to back off the *encoder* for a while.
- There's still the IntegerEncoder.supportCompactZero flag which
- enables compact encoding form whenever it evaluates to True.
- - Report package version on debugging code initialization.
- Revision 0.1.5
- --------------
- - Documentation updated and split into chapters to better match
- web-site contents.
- - Make prettyPrint() working for non-initialized pyasn1 data objects. It
- used to throw an exception.

- - Fix to decoder to support empty-payload INTEGER and REAL values
- - Fix to unit test suites imports to be able to run each from
- their current directory
- Revision 0.1.4
- --------------
- - Built-in codec debugging facility added
- - Added some more checks to ObjectIdentifier BER encoder catching
- posible 2^8 overflow condition by two leading sub-OIDs
- - Implementations overriding the AbstractDecoder.valueDecoder method
- changed to return the rest of substrate behind the item being processed
- rather than the unprocessed substrate within the item (which is usually
- empty).
- - Decoder's recursiveFlag feature generalized as a user callback function
- which is passed an uninitialized object recovered from substrate and
- its uninterpreted payload.
- - Catch inappropriate substrate type passed to decoder.
- - Expose tagMap/typeMap/Decoder objects at DER decoder to uniform API.
- - Obsolete __init__.MajorVersionId replaced with __init__.__version__
- which is now in-sync with distutils.
- - Package classifiers updated.
- - The __init__.py's made non-empty (rumors are that they may be optimized
- out by package managers).
- - Bail out gracefully whenever Python version is older than 2.4.
- - Fix to Real codec exponent encoding (should be in 2's complement form),
- some more test cases added.
- - Fix in Boolean truth testing built-in methods
- - Fix to substrate underrun error handling at ObjectIdentifier BER decoder
- - Fix to BER Boolean decoder that allows other pre-computed
- values besides 0 and 1
- - Fix to leading 0x80 octet handling in DER/CER/DER ObjectIdentifier decoder.
- See http://www.cosic.esat.kuleuven.be/publications/article-1432.pdf

- + drop explicit long integer type use
- + map()/filter() replaced with list comprehension

- Revision 0.0.5a
- ---------------
- - Integer BER codec reworked fixing negative values encoding bug.
- - clone() and subtype() methods of Constructed ASN.1 classes now

- performance reasons (this may affect backward compatibility).
- Performance penalty may be huge on deeply nested Constructed objects
- re-creation.
- - Base ASN.1 types (pyasn1.type.univ.*) do not have default values
- anymore. They remain uninitialized acting as ASN.1 types. In
- this model, initialized ASN.1 types represent either types with
- default value installed or a type instance.
- - Decoders' prototypes are now class instances rather than classes.
- This is to simplify initial value installation to decoder's
- prototype value.
- - Bugfix to BitString BER decoder (trailing bits not regarded).
- - Bugfix to Constraints use as mapping keys.
