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 encoder to produce empty-payload INTEGER values for zeros +- 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 + +Revision 0.1.3 +-------------- + +- Include class name into asn1 value constraint violation exception. +- Fix to OctetString.prettyOut() method that looses leading zero when + building hex string. + +Revision 0.1.2 +-------------- + +- Fix to __long__() to actually return longs on py2k +- Fix to OctetString.__str__() workings of a non-initialized object. +- Fix to quote initializer of OctetString.__repr__() +- Minor fix towards ObjectIdentifier.prettyIn() reliability +- ObjectIdentifier.__str__() is aliased to prettyPrint() +- Exlicit repr() calls replaced with '%r' + +Revision 0.1.1 +-------------- + +- Hex/bin string initializer to OctetString object reworked + (in a backward-incompatible manner) +- Fixed float() infinity compatibility issue (affects 2.5 and earlier) +- Fixed a bug/typo at Boolean CER encoder. +- Major overhawl for Python 2.4 -- 3.2 compatibility: + + get rid of old-style types + + drop string module usage + + switch to rich comparation + + drop explicit long integer type use + + map()/filter() replaced with list comprehension + + apply() replaced with */**args + + switched to use 'key' sort() callback function + + support both __nonzero__() and __bool__() methods + + modified not to use py3k-incompatible exception syntax + + getslice() operator fully replaced with getitem() + + dictionary operations made 2K/3K compatible + + base type for encoding substrate and OctetString-based types + is now 'bytes' when running py3k and 'str' otherwise + + OctetString and derivatives now unicode compliant. + + OctetString now supports two python-neutral getters: asOcts() & asInts() + + print OctetString content in hex whenever it is not printable otherwise + + in test suite, implicit relative import replaced with the absolute one + + in test suite, string constants replaced with numerics + +Revision 0.0.13 +--------------- + +- Fix to base10 normalization function that loops on univ.Real(0) + +Revision 0.0.13b +---------------- + +- ASN.1 Real type is now supported properly. +- Objects of Constructed types now support __setitem__() +- Set/Sequence objects can now be addressed by their field names (string index) + and position (integer index). +- Typo fix to ber.SetDecoder code that prevented guided decoding operation. +- Fix to explicitly tagged items decoding support. +- Fix to OctetString.prettyPrint() to better handle non-printable content. +- Fix to repr() workings of Choice objects. + +Revision 0.0.13a +---------------- + +- Major codec re-design. +- Documentation significantly improved. +- ASN.1 Any type is now supported. +- All example ASN.1 modules moved to separate pyasn1-modules package. +- Fix to initial sub-OID overflow condition detection an encoder. +- BitString initialization value verification improved. +- The Set/Sequence.getNameByPosition() method implemented. +- Fix to proper behaviour of PermittedAlphabetConstraint object. +- Fix to improper Boolean substrate handling at CER/DER decoders. +- Changes towards performance improvement: + + all dict.has_key() & dict.get() invocations replaced with modern syntax + (this breaks compatibility with Python 2.1 and older). + + tag and tagset caches introduced to decoder + + decoder code improved to prevent unnecessary pyasn1 objects creation + + allow disabling components verification when setting components to + structured types, this is used by decoder whilst running in guided mode. + + BER decoder for integer values now looks up a small set of pre-computed + substrate values to save on decoding. + + a few pre-computed values configured to ObjectIdentifier BER encoder. + + ChoiceDecoder split-off SequenceOf one to save on unnecessary checks. + + replace slow hasattr()/getattr() calls with isinstance() introspection. + + track the number of initialized components of Constructed types to save + on default/optional components initialization. + + added a shortcut ObjectIdentifier.asTuple() to be used instead of + __getitem__() in hotspots. + + use Tag.asTuple() and pure integers at tag encoder. + + introduce and use in decoder the baseTagSet attribute of the built-in + ASN.1 types. + +Revision 0.0.12a +---------------- + +- The individual tag/length/value processing methods of + encoder.AbstractItemEncoder renamed (leading underscore stripped) + to promote overloading in cases where partial substrate processing + is required. +- The ocsp.py, ldap.py example scripts added. +- Fix to univ.ObjectIdentifier input value handler to disallow negative + sub-IDs. + +Revision 0.0.11a +---------------- + +- Decoder can now treat values of unknown types as opaque OctetString. +- Fix to Set/SetOf type decoder to handle uninitialized scalar SetOf + components correctly. + +Revision 0.0.10a +---------------- + +- API versioning mechanics retired (pyasn1.v1 -> pyasn1) what makes + it possible to zip-import pyasn1 sources (used by egg and py2exe). + +Revision 0.0.9a +--------------- + +- Allow any non-zero values in Boolean type BER decoder, as it's in + accordnance with the standard. + +Revision 0.0.8a +--------------- + +- Integer.__index__() now supported (for Python 2.5+). +- Fix to empty value encoding in BitString encoder, test case added. +- Fix to SequenceOf decoder that prevents it skipping possible Choice + typed inner component. +- Choice.getName() method added for getting currently set component + name. +- OctetsString.prettyPrint() does a single str() against its value + eliminating an extra quotes. + +Revision 0.0.7a +--------------- + +- Large tags (>31) now supported by codecs. +- Fix to encoder to properly handle explicitly tagged untagged items. +- All possible value lengths (up to 256^126) now supported by encoders. +- Fix to Tag class constructor to prevent negative IDs. + +Revision 0.0.6a +--------------- + +- Make use of setuptools. +- Constraints derivation verification (isSuperTypeOf()/isSubTypeOf()) fixed. +- Fix to constraints comparation logic -- can't cmp() hash values as it + may cause false positives due to hash conflicts. + +Revision 0.0.5a +--------------- + +- Integer BER codec reworked fixing negative values encoding bug. +- clone() and subtype() methods of Constructed ASN.1 classes now + accept optional cloneValueFlag flag which controls original value + inheritance. The default is *not* to inherit original value for + 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. +- Bugfix to Integer & BitString clone() methods +- Bugix to the way to distinguish Set from SetOf at CER/DER SetOfEncoder +- Adjustments to make it running on Python 1.5. +- In tests, substrate constants converted from hex escaped literals into + octals to overcome indefinite hex width issue occuring in young Python. +- Minor performance optimization of TagSet.isSuperTagSetOf() method +- examples/sshkey.py added + +Revision 0.0.4a +--------------- + +* Asn1ItemBase.prettyPrinter() -> *.prettyPrint() + +Revision 0.0.3a +--------------- + +* Simple ASN1 objects now hash to their Python value and don't + depend upon tag/constraints/etc. +* prettyIn & prettyOut methods of SimplleAsn1Object become public +* many syntax fixes + +Revision 0.0.2a +--------------- + +* ConstraintsIntersection.isSuperTypeOf() and + ConstraintsIntersection.hasConstraint() implemented +* Bugfix to NamedValues initialization code +* +/- operators added to NamedValues objects +* Integer.__abs__() & Integer.subtype() added +* ObjectIdentifier.prettyOut() fixes +* Allow subclass components at SequenceAndSetBase +* AbstractConstraint.__cmp__() dropped +* error.Asn1Error replaced with error.PyAsn1Error + +Revision 0.0.1a +--------------- + +* Initial public alpha release -- cgit v1.2.3
