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). --- lib/asn1/src/asn1ct_check.erl | 105 +++++--------- lib/asn1/src/asn1ct_constructed_ber_bin_v2.erl | 3 +- lib/asn1/src/asn1ct_constructed_per.erl | 71 ++++++--- lib/asn1/src/asn1ct_gen.erl | 44 +++++- lib/asn1/src/asn1ct_imm.erl | 23 ++- lib/asn1/src/asn1rtt_check.erl | 91 +++++++----- lib/asn1/src/asn1rtt_per_common.erl | 41 ++++++ lib/asn1/test/asn1_SUITE.erl | 36 ++--- lib/asn1/test/asn1_SUITE_data/Default.asn | 3 +- lib/asn1/test/asn1_SUITE_data/PrimStrings.asn1 | 8 +- lib/asn1/test/testParamBasic.erl | 7 +- lib/asn1/test/testPrimStrings.erl | 41 +++++- lib/asn1/test/testSeqSetDefaultVal.erl | 191 ++++++++++++++++++++++--- 13 files changed, 487 insertions(+), 177 deletions(-) (limited to 'lib/asn1') diff --git a/lib/asn1/src/asn1ct_check.erl b/lib/asn1/src/asn1ct_check.erl index eddcda0018..04227fd23b 100644 --- a/lib/asn1/src/asn1ct_check.erl +++ b/lib/asn1/src/asn1ct_check.erl @@ -2534,89 +2534,54 @@ normalize_integer(S,Int=#'Externalvaluereference'{value=Name},Type) -> normalize_integer(_,Int,_) -> exit({'Unknown INTEGER value',Int}). -normalize_bitstring(S,Value,Type)-> - %% There are four different Erlang formats of BIT STRING: - %% 1 - a list of ones and zeros. - %% 2 - a list of atoms. - %% 3 - as an integer, for instance in hexadecimal form. - %% 4 - as a tuple {Unused, Binary} where Unused is an integer - %% and tells how many bits of Binary are unused. - %% - %% normalize_bitstring/3 transforms Value according to: - %% A to 3, - %% B to 1, - %% C to 1 or 3 - %% D to 2, - %% Value can be on format: - %% A - {hstring, String}, where String is a hexadecimal string. - %% B - {bstring, String}, where String is a string on bit format - %% C - #'Externalvaluereference'{value=V}, where V is a defined value - %% D - list of #'Externalvaluereference', where each value component - %% is an identifier corresponing to NamedBits in Type. - %% E - list of ones and zeros, if Value already is normalized. +%% normalize_bitstring(S, Value, Type) -> bitstring() +%% Convert a literal value for a BIT STRING to an Erlang bit string. +%% +normalize_bitstring(S, Value, Type)-> case Value of {hstring,String} when is_list(String) -> - hstring_to_int(String);
