* dgud/asn1/fix-seqtag/OTP-12326:
asn1: Fix EXTERNAL (1994 variant) type conversion
|
|
Missed to add seqtag handling for EXTERNAL type conversion,
bug introduced in c266196c016fc1156c7a18cfeec4920ee4075519
|
|
|
|
According to the BER encoding rules, only constructed values may
have indefinite lengths. A primitive value must be encoded with
a definite length.

The following type of code would crash the compiler:
OSET SOME-CLASS ::= {OSET1, ..., OSET2}
|
|
Attempting to compile:
SomeType{SOME-CLASS-NAME, SOME-CLASS-NAME:SomeSet} ::= ...
SEQUENCE {
something SOME-CLASS-NAME.&id({SomeSet})
}
would crash the compiler, because the actual parameter for
SOME-CLASS-NAME was not substituted into the governor for
the SomeSet parameter.
While we are at it, combine the functionality of is_class/2
and get_class_def/2 (eliminating is_class/2). Most callers
call both function.

|
|
The code generator would crash.

If SetIn is defined like this:
SetIn ::= SET {
boolIn BOOLEAN,
intIn INTEGER
}
then it may not be used with an empty DEFAULT value like this:
SetDef1 ::= SET {
set1 SetIn DEFAULT {}
}
The ASN.1 compiler prints an warning message, but still generates
code. (That should be fixed.)
Fix the incorrect ASN.1 specification by making the
components in SetIn optional:
SetIn ::= SET
{
boolIn BOOLEAN OPTIONAL,
intIn INTEGER OPTIONAL
}
|
|
|
|
This will also eliminate a dialyzer warning for unmatched returns,
and increase the coverage.

Attempting to subtype an extensible ENUMERATED like this:
BaseType ::= { foo, bar, ... }
SubType ::= BaseType ( foo )
would fail to compile with a message that 'foo' was undefined.

* bjorn/asn1/fix-integer-constraint/OTP-11504:
PER/UPER: Handle a range in the extension part of the constraint
|
|
Constraints such as:
INTEGER (1..10, ..., 11..20)
would fail to compile. Make sure it is properly ignored.
|

* bjorn/asn1/fix-union-bug/OTP-11411:
Fix complicated union of INTEGER constraints
|

* bjorn/asn1/fix-extensible-single-values/OTP-11415:
PER/UPER: Correct encoding for single-value extensible constraints
asn1ct_value: Handle named INTEGERs with constraints
|
|
A constraint that was an union of integer ranges:
Type ::= INTEGER (lb1..ub1 | ... | lbN..ubN)
would sometimes (depending on the values) not all always be properly
combined to a single effective range, but would become:
Type ::= INTEGER (lb2..ub2) (lb3..ub3)
If that type was used in a SEQUENCE:
S ::= SEQUENCE {
v Type
}
the constraint would be simplified, taking the intersection of the
ranges.

For DER/PER/UPER, a value equal to the DEFAULT is not supposed to
be encoded.
BIT STRINGs values can be represented as Erlang terms in four
different ways: as an integer, as a list of zeroes and ones,
as a {Unused,Binary} tuple, or as an Erlang bitstring.
When encoding a BIT STRING, only certain representations of
BIT STRINGs values were recognized. All representations must
be recognized.
When decoding a DEFAULT value for a BIT STRING, the actual value
given in the decoding would be either an integer or a list
of zeroes and one (depending on how the literal was written in
the specification). We expect that the default value should be
in the same representation as any other BIT STRING value (i.e.
by default an Erlang bitstring, or a list if the 'legacy_bitstring'
option has been given, or as compact bitstring if 'compact_bitstring'
has been given).

An extensible constraint which is a union of single values, such as:
INTEGER (1|17, ...)
would be incorrectly encoded.

asn1_test_lib is supposed to be a general-purpose helper module for
test cases. Move all specific test cases into asn1_SUITE.
|
|
|
|
|
|
|
|
|
|
Also extend the test suite with more tests of inlined constructs
in object sets.

* bjorn/asn1/not-small-bugs/OTP-11153:
PER/UPER: Correct decoding of SEQUENCEs with more than 64 extensions
testConstraints: Improve tests of semi-constrained INTEGERs
Test ENUMERATED with many extended values
UPER: Correct encoding of ENUMERATED with more than 63 extended values
Add asn1_test_lib:hex_to_bin/1

When a SEQUENCE was defined inline inside extension addition group
like this:
InlinedSeq ::= SEQUENCE {
...,
[[
s SEQUENCE {
a INTEGER,
b BOOLEAN
}
]]
}
the decoding code would return the contents of the SEQUENCE in a
record named 'InlinedSeq_ExtAddGroup1_s', while the record definition
in the generated HRL file would be 'InlinedSeq_s'.
Since there is no reason to use the longer record name (no risk for
ambiguity), correct the name in the decoding code.

Simplify the backends by letting asn1ct_check replacing a
with the actual type.
|
|
Given:
Semi ::= INTEGER (Lb..MAX, ...)
where Lb is an arbitrary integer, attempting to encode an
integer less than Lb would cause the encoder to enter an
infinite loop.
|
|
A semi-constrained INTEGER with a non-zero lower bound would be
incorrectly decoded. This bug was introduced in R16.
|
|
While at it, also test more integer values.
|
|
|
|
For the PER backends, generate code for accessing deep table
constraints at compile-time in the same way as is done for BER.
While at it, remove the complicated indentation code.
Also modernize the test suite and add a test for a deeper nested
constraint.

Unify the code for checking an enumeration value named in a
DEFAULT and in an ENUMERATED value. There is no need to handle
those cases differently. That also will also make sure that
the following works:
E ::= ENUMERATED { x, ..., y }
e E ::= x
(Extensible ENUMERATEDs were not handled when defining values.)
Always generate an error when an unknown enumeration value is
given (used in a DEFAULT, a message would be printed, but the
compilation would succeed). Also make sure that we always include
the line number for the incorrect enumeration.
Write a new test case and remove the extremely rudimentary
value_bad_enum_test/1 test case.
|
|
The list of files to remove was obtained by running "ls -lut"
after running the test cases and comparing the atime for each
file with the start of the test run.
|
|
For the example from X.691, make sure to test that our encoded
value is the same as given in X.691.
Run the test for BER, too.
