2017-08-16Fix broken handling of default values in extensions for PERBjörn Gustavsson
Default values have never worked in extension for PER. Note that for default values in the root part of SEQUENCE, giving a value equal to the DEFAULT value, will result in the same encoding as if asn1_DEFAULT was given. However, that behavior is not promised by the documentation. The documentation says that asn1_DEFAULT should be used for default values. For DEFAULT in extensions, only implement what the documentation promises and nothing more. ERIERL-60

2017-07-04Corrected behavior of option {n2n, EnumTypeName} whenKenneth Lundin
EnumTypeName contains a hypen like fore example Cause-Misc. This caused syntax errors when compiling the generated Erlang code.

2017-03-27Add a no_native option wherever there is an on_loadKostis Sagonas
This is a poor man's solution that allows to build and test the system with all files compiled to native code simply by setting the ERL_COMPILER_OPTS environment variable. Better solutions, like automatically setting the no_native option whenever the compiler sees an on_load attribute, obviously exist but require more time to implement.
2017-03-15Remove default clauses that cause exceptions for internal errorsBjörn Gustavsson
Just crash if there is an internal error.

2017-03-14Clean up use of asn1ct_gen:emit/1Björn Gustavsson
Stop up using asn1ct_gen:emit/1 with a tuple instead of a list. Also remove the remaining uses of asn1ct_gen:demit/1.

That will make code slightly easier to read.
2017-03-14asn1ct_gen_ber_bin_v2: Remove unused codeBjörn Gustavsson
The code is not covered. The code is also not present in the PER backend. Here is a somewhat more formal proof that the code cannot be reached: asn1ct_gen_ber_bin_v2:gen_encode_user/3 calls asn1ct_gen:gen_encode_constructed/4 where Typename is a list of one element. asn1ct_gen:gen_encode_constructed/4 will call asn1ct_gen_ber_bin_v2:gen_encode/3 via asn1ct_gen:gen_types/4. Note that if InnerType in asn1ct_gen:gen_encode_constructed/4 is 'SEQUENCE OF' or 'SET OF', Typename will be extended to a list with two elements. If InnerType in asn1ct_gen:gen_encode_constructed/4 is 'SET', 'SEQUENCE', or 'CHOICE', then asn1ct_gen_ber_bin_v2:gen_encode/3 will be called with the last argument being a #'ComponentType'{}. asn1ct_gen_ber_bin_v2:gen_encode/3 will in that cause extend Typename before calling itself recursively. Therefore, Typename is always a list with at least two elements when the removed code is called.
2017-03-14asn1ct_gen_per: Fix broken dialyzer suppression functionBjörn Gustavsson
ce431409d0daba broke generation of dialyzer suppressions for per and uper. While we are it, add type tests to asn1ct_func:is_used/1 to avoid similar problems in the future.

2017-02-21encode/decode: Include the stack trace in error returnsBjörn Gustavsson
The generated encode/2 and decode/2 functions can return cryptic error messages. Consider this ASN.1 spec: T DEFINITIONS AUTOMATIC TAGS ::= BEGIN S ::= SEQUENCE { b BOOLEAN, i INTEGER (1..100), j INTEGER (0..7), s OCTET STRING } END In OTP 19, the error terms will look like this: Eshell V8.2 (abort with ^G) 1> asn1ct:compile('T', [ber]). ok 2> rr('T'). ['S'] 3> 'T':encode('S', #'S'{}). {error,{asn1,{encode_boolean,undefined}}} 4> 'T':encode('S', #'S'{b=false}). {error,{asn1,{encode_integer,undefined}}} 5> 'T':encode('S', #'S'{b=false,i=7,j=0}). {error,{asn1,function_clause}} Some error terms are clearer than other. In the first error term, it is clear that the error refers to the 'b' field, since there is only one BOOLEAN in 'S'. The second error term could refer to either 'i' or 'j'. The last error term... well... in this case we can infer that it must refer to 's'. The easiest way to provide more information is to include the stack trace with line numbers in the error term: 3> 'T':encode('S', #'S'{b=false}). {error,{asn1,{{encode_integer,undefined}, [{'T',encode_integer,2,[{file,"T.erl"},{line,240}]}, {'T',enc_S,2,[{file,"T.erl"},{line,102}]}, {'T',encode,2,[{file,"T.erl"},{line,36}]}, {erl_eval,do_apply,6,[{file,"erl_eval.erl"},{line,674}]}, {shell,exprs,7,[{file,"shell.erl"},{line,686}]}, {shell,eval_exprs,7,[{file,"shell.erl"},{line,641}]}, {shell,eval_loop,3,[{file,"shell.erl"},{line,626}]}]}}} By looking at the generated Erlang code, we can see that encoding failed for 'i'. This is an compatible change. All that the documentation says is that the format of the error tuple is: {error,{asn1,Description}} With this change, Description is always a tuple: {ErrorDescription,StackTrace} Alternatives considered: Providing more information in the error term itself and make sure there can be no 'function_clause', 'badarg', or 'badmatch' exceptions. That would be possible, but it would require a lot of work and it would increase the size of the generated code and make it slower. Therefore, this solution was rejected.
2017-02-21PER decoding: Be less verbose for invalid ENUMERATEDBjörn Gustavsson
When an invalid value is encountered when trying to decode an ENUMERATED, the exception can be quite verbose. Here is an actual example from NBAP-PDU-Contents: _ -> exit({error,{asn1,{decode_enumerated,{V4@V3,[chCode1div1,chCode2div1,chCode2div2,chCode4div1,chCode4div2,chCode4div3,chCode4div4,chCode8div1,chCode8div2,chCode8div3,chCode8div4,chCode8div5,chCode8div6,chCode8div7,chCode8div8,chCode16div1,chCode16div2,chCode16div3,chCode16div4,chCode16div5,chCode16div6,chCode16div7,chCode16div8,chCode16div9,chCode16div10,chCode16div11,chCode16div12,chCode16div13,chCode16div14,chCode16div15,chCode16div16]}}}}) Listing the possible values for an ENUMERATED when decoding fails is not helpful and increases the code size (it would have made somewhat more sense to list the possible values if *encoding* failed).
2017-02-17PER encoding: Emit comments about each attributeBjörn Gustavsson
To make it easier to find your way in the generated code, add a comment about each attribute in the generated code for SEQUENCE and SET.
2017-02-17PER: Slightly improve error reporting for encodingBjörn Gustavsson
Generate slightly better error reasons when encoding of INTEGER, ENUMERATED, or BOOLEAN fails.

2017-02-06Teach the ASN.1 compiler the 'maps' optionBjörn Gustavsson
When the 'maps' option is given, the SEQUENCE and SET types are represented as maps instead of as records. Optional and default values must be not be given as asn1_NOVALUE or asn1_DEFAULT in a map passed to the M:encode/2 function; they must be omitted from the map. Similarly, when decoding missing values will be omitted from the map. No .hrl files will be generated when the 'maps' options is used. That means values in an ASN.1 module must be retrieved by calling the appropriate function in generated module. Since we one day hope to get rid of the options 'compact_bit_string', 'legacy_bit_string', and 'legacy_erlang_types', we will not allow them to be combined with the 'maps' option.
2017-02-03Refactor decoding as a preparation for handling mapsBjörn Gustavsson
2017-02-03Refactor encoding of optional valuesBjörn Gustavsson
As a preparation for supporting maps in a future commit, refactor the functions for encoding optional values.
2017-02-03Clean up filtering of optionsBjörn Gustavsson
2017-02-03Refactor code generation optionsBjörn Gustavsson
Most options to the code generation pass are passed through the process dictionary. At the same time, an Erule or Erules argument is passed to most code generation functions. The Erule argument is only an atom indicating the encoding rules ('ber', 'per', or 'uper'). Introduce a new record #gen{} to contain code generation options and parameters. Pass it as the Erule argument (renaming it to Gen in functions that we will have to touch anyway). In this commit, eliminate the use of the variable 'encoding_options' in the process dictionary.
2017-02-03Simplify gen_enc_components_call() and friendsBjörn Gustavsson
2017-02-03asn1ct_check: Number the components in INSTANCE OFBjörn Gustavsson
asn1ct_check numbers all components in SEQUENCEs and SETs, except for the associated sequence for INSTANCE OF. Remove this exception so that the code generation pass can depend on SEQUENCEs being numbered.
2017-02-03Refactor gen_encode_constructed_imm/3Björn Gustavsson
Introduce helper functions to simplify and reduce the size of gen_encode_constructed_imm/3.
2017-02-03Clean up handling of textual orderBjörn Gustavsson
The to_encoding_order/1 function can be eliminated if we incorporate its functionality into textual_order/2. textual_order/2 has a workaround for TermList being longer than OrderList. Remove the workaround, because the code being generated would certainly be wrong (better let the compiler crash and receive a bug report if it happens). The workaround was not necessary to successfully compile the entire Erlang/OTP and to run the asn1 test suite.
2017-02-03Break apart function with 6 argumentsBjörn Gustavsson
As a preparation for future changes, simplify gen_dec_constructed_imm_2/6 by breaking it apart to two functions.
2017-01-13asn1: Remove deprecated functionsBjörn Gustavsson
Remove the entire asn1rt module. All functions in it were deprecated in OTP 17. In asn1ct, remove the deprecated functions asn1ct:encode/3 and asn1ct:decode/3. Also remove asn1ct:encode/2, which has not been formally deprecated but is undocumented.
