Support in BER was removed in 3d1279f3cebfdd2483c3afea9f225613fe45cd00.

Add the option 'legacy_bit_string' to decode to the old list format.
|
|
There are two different definitions of the EXTERNAL data type in ASN.1:
the original from 1990 and an updated from 1994. Both defintions
are encoded in the same way (in BER). There are still
systems in use that use the old definition of EXTERNAL, so the
asn1 application must still support both.
It has been decided that the asn1 application should handle both
the forms without any compiler options. Internally the asn1 application
uses the 1990 definition. The encode functions will accept both
definitions, but translate the 1994 format to the 1990 format
if needed. When decoding, it will decode to the 1990 definition format
first and then translate to the 1994 defintion format.
One problem with this approach is that the conversion to the 1994
format may not be loss-less (where the 1990 defintion had a CHOICE
between an OPEN TYPE, OCTET STRING, or BIT STRING, the 1994 definition
only supports an OCTET STRING), and therefore it might not be possible
to correctly re-encode the data in the 1990 format.
It seems that the only reliable way to handle that problem is to not
do the conversion to the 1994 format if the conversion is not
loss-less. (There is an attempt when translating to the 1990 format
to recover the CHOICE alternative based on the Erlang type of
the data value, but that is neither reliable nor future-proof.)
That is, when decoding an EXTERNAL value, the resulting
tuple could either conform to the 1990 or 1994 definition, and
applications must be prepared to handle that.

Always pre-encode the values for the enumeration. Clean up the
code and let the per and uper back-ends share the code.
|
|
enif_make_new_binary() cannot return NULL, so while at it,
remove the check for return value of enif_make_new_binary()
being NULL.
|
|
Also make sure that the error handling is contained within the
asn1rt_nif module and does not leak out to generated code.

The template modules (asn1rtt_*.erl) are based on the existing
run-time modules, but with some simplifications and improvements,
for example:
The run-time functions for BER encoding took a Constraint argument which
was not used. It has been eliminated, along with the unused StringType
argument for the encode_restricted_string function.
The Range argument for decode_enumerated() has been dropped since it
was not used.

* bjorn/asn1/extension-addition-groups/OTP-10664:
Fix a bug for multiple extension addition groups
|
|
Encoding would fail.
|
|
|
|
Support for the notation was removed in 6ef8cbdaaaa1c30a7dc462063.
|
|
The constraint simplification pass need to be seriously rethought
and rewritten.
As a starting point, add a test case to test that equivalent ways
to write a constraint are reduced to the same simplified constraint.
Fix a few obvious bugs to make the test cases to pass.
|
|
Extensions following a double bracket group were not skipped correctly.
Fix this bug and add tests to ensure that extensions are skipped
correctly.
|
|
|
|
Also run the test case for all back-ends.
|
|
|
|
|
|
|
|
Make the test suite more readable by introducing and using a
roundtrip/2 function.
|
|
|
|
|
|
Eliminate the spawning of the process since the original bug is
fixed.
|
|
|
|
Decoding of fragmented OCTET STRINGs was only implemented when the size
was constrained to a single value. While at it, support decoding
fragmented OCTET STRINGS in all circumstances.
|
|
|
|
Reduce verbosity and introduce readability by introducing the roundtrip/2
function. That will help us to do future extensions to this test suite.

It is time to clean up the mess of back-ends.
Remove all the obsolete back-ends and simplify the options used
to select them.
New Option Old Equivalent
---------- --------------
ber ber_bin,optimize,nif
per per,optimize,nif
uper uper_bin
The old options will still be recognized and translated to the
new options, but will also print a warning.
That implies that deprecated features that only are implemented
in the old 'ber' back-end will no longer work (e.g. the
{Typename,Value} notation).
Also make the return type for the generated encode/2 function
consistent. It used to be a binary for per and uper, and an iolist
for ber. Always make it a binary.
|
|
As a preparation for removing obsolete back-ends, remove tests
for the {TypeName,Value} notation to avoid having those test cases
fail.
|
|
The 'keyed_list' was only supported for the 'ber' and 'ber_bin'
backends and has been undocumented for a long time. Also remove
the note in the documentation about the feature.

Use ct:timetrap/1 instead of test_server:timetrap/1 for really long
test_cases.
Commontest sets up a default timetrap on 30 min, which is not cancelled
if testserver:timetrap called.

Fix a bug where a subtyped single value integer type where one or more values
were predefined would result in generated encoding code having faulty range

Encoding and decoding of integer ranges can now be done
with an upper bound larger than the previous limit of 16^10.
The new upper bound in per encoding and decodings for constrained
whole numbers is 2^2040 (close to 16^508) which is the limit if
the length field encoding in the encoding of a constrained
whole number is limited to a single octet.
