In order to optimize the generated code, we will need data structures
that can be traversed in several passes before the actual code is
generated.
Refactor the code so that if first builds (essentially) a list of
funs that do the actual code generation, and a second function
that will call the funs one at the time.

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.
|
|
Decoding of a fragmented OCTET STRING with the size constrained to a
single value is implemented, but encoding is not implemented, and
decoding is not tested in any test case.
There is no urgent need to support encoding of fragmented OCTET STRINGs,
but not being able to encode such values complicates testing of decoding.
For example, eif we add the following type to PrimStrings.asn1 in the test
suite:
FixedOs65536 ::= OCTET STRING (SIZE (65536))
then asn1ct:test('PrimStrings') will fail because this value cannot
be encoded.
|
|
A long term goal is to eleminate the asn1ct_gen_per_rt2ct module
in favor of the asn1ct_gen_per module, so will have
asn1ct_gen_per_rt2ct call asn1ct_gen_per.

It is error-prone to have several copies of the same function.

Don't waste time calling a trivial function in the run-time library
for encoding and decoding of NULL values.

Currently, the generated code suppresses warnings for unusued variables
by assigning to the "_Val" variable, for example:
_Val = Tmpval5
To be completely safe, that should have been:
_ = Tmpval5
in case there happens to more than one such assignment in the same
scope.
However, a better way to suppress warnings is to simply use the
'nowarn_unused_vars' compiler option. That method will also work
for more complicated expressions there it would be cumbersome to
suppress warnings by assignment to "_".

While at it, also make the generated code for the attributes
more readable.

The NIF library is now mandatory.
The call to application:get_env/2 to find out whether the NIF
library is loaded is surprisingly expensive.

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.
|
|
|
|
Of the back-ends that we are going to keep, only the UPER back-end
support the obsolete {Typename,Value} notation. For consistency
with the PER and BER encodings, remove the support for UPER
encoding too. Also remove vestiges of the support for the
notation in the other back-ends.
|
|
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.

the values used for generating the range check in case of
a value range should be sorted and have duplicates removed.
For per with optimization (per_rt2ct), sorting has been
added. For both optimized and regular per, the sorting and
duplicate removal code has been simplified.
In case of value range, 'MIN' and 'MAX' is now also checked.
The sorting of constraint values in the check phase remains.

|

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.
