For example:
AttributeTypeAndValues ::= SEQUENCE {
type OBJECT IDENTIFIER,
values SET OF ANY DEFINED BY type
}
This patch adds support of the above ASN.1 syntax to BER/DER/CER
codecs.
It appears that to implement this feature properly, `SetOf`/`SequenceOf`
pyasn1 types need to have `.componentType` wrapped into something
similar to `NamedType` that `Set`/`Sequence` have. That additional
layer would then carry the open type meta information. Without it,
`Sequence`/`Set` codec needs to signal `SetOf`/`SequenceOf` codec
of the open type being processed, which is a slight hack.
A other inconvenience is that when `SetOf`/`SequenceOf` deal with
an open type component, they should not verify types on component
assignment. Without open type property in `SetOf`/`SequenceOf`,
the code checks for `Any` component type which is another hack.
The above shortcomings should be addressed in the follow up patch.

- Added support for subseconds CER/DER encoding edge cases in
`GeneralizedTime` codec
- Fixed 3-digit fractional seconds value CER/DER encoding of
`GeneralizedTime`

The new exception classes names are `PyAsn1UnicodeDecodeError`
and `PyAsn1UnicodeEncodeError`.
Also, unit tests added.
|
| |
|

This change helps telling unicode-related exceptions from other PyAsn1Error exceptions.

Fixes `AnyDecoder` to accept `TagMap` as `asn1Spec`.
The use-case is to make `AnyDecoder` operational when
dumping raw value on error condition is enabled

* Add `omitEmptyOptionals` encoder option
Added `omitEmptyOptionals` option which is respected by `Sequence`
and `Set` encoders. When `omitEmptyOptionals` is set to `True`, empty
initialized optional components are not encoded. Default is `False`.
* Change `SequenceOf`/`SetOf` behaviour
- New elements to `SequenceOf`/`SetOf` objects can now be added at any
position - the requirement for the new elements to reside at the end
of the existing ones (i.e. s[len(s)] = 123) is removed.
- Removed default initializer from `SequenceOf`/`SetOf` types to ensure
consistent behaviour with the rest of ASN.1 types. Before this change,
`SequenceOf`/`SetOf` instances immediately become value objects
behaving like an empty list. With this change, `SequenceOf`/`SetOf`
objects remain schema objects unless a component is added or
`.clear()` is called.
- Added `.reset()` method to all constructed types to turn value object
into a schema object.

When SEQUENCE has defaulted component of constructed type,
recursively instantiate defaulted component and assign instantiated
asn1 object to SEQUENCE field.

More debug logging added to BER family of codecs to
ease encoding problems troubleshooting.
Also:
* code layout made a bit more sparse
* potential bug in open type decoding in indefinite mode
fixed
|
| |
|
|
|
|
|
|

Debug logging refactored for more efficiency when
disabled and for more functionality when in use.
Specifically, the global LOG object can easily be used
from any function/method, not just from codec main loop
as it used to be.

When calling `.prettyPrint()` on Sequence/Set components,
make sure the component is a value object (not schema)
because calling `.prettyPrint` on a schema object is
likely to fail.

It appears that Python 3.7 use in Travis-CI is finally
fixed. However, it requires use of xenial distribution
and sudo: true. Those have now been added to the matrix.

The type map should include all ASN.1 types rather
than just ambiguous ones for performance reasons.
Incomplete type ID map triggers building a new
TagSet out of the value being encoded. If that
value does not have base tags set, that leads to
a crash.

The wheel package format supports including the license file. This is
done using the [metadata] section in the setup.cfg file. For additional
information on this feature, see:

Not all implementations have to implement getsizeof() and may raise
TypeError instead. Notably, Pypy will always raise TypeError (unless a
default value is provided).

localize explicit tag slitting to chunked mode at OctetString and BitString encoders
The inner chunks tagging logic is to be researched -- I'm not certain it works as it supposed to

* __str__() of ASN.1 types reworked to serve instead of .prettyPrint()
Related changes: `str()` on enumerations and boolean will return
a string label rather than a number.
