| 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 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 | |
