2015-01-12Move checking of UNIQUE & DEFAULT error to asn1ct_checkBjörn Gustavsson
To keep the error reporting code in asn1ct_parser2 simple, we only want to handle pure syntactic errors. Therefore, move the check that UNIQUE and DEFAULT are not applied to the same field to asn1ct_check.
2015-01-12Makefile: Add missing dependency for asn1ct_gen_checkBjörn Gustavsson
asn1ct_gen_check.erl was added in 7df687d6.
2015-01-12Strengthen the test of selection typesBjörn Gustavsson
"SET OF id < Type" was not tested. Also make sure that all of assigned values are correct.
2015-01-12Remove code duplicationDan Gudmundsson
2015-01-12Remove unnecessary internal errorsBjörn Gustavsson
2015-01-12Modernize error handling for SEQUENCEDan Gudmundsson
While we are at it, also remove an unreachable (too many extensions) error case.
2015-01-12Modernize error handling for CHOICEDan Gudmundsson
2015-01-12Modernize error handling for BOOLEANDan Gudmundsson
2015-01-12Modernize error handling for named valuesDan Gudmundsson
2015-01-12Rewrite checking of ENUMERATEDBjörn Gustavsson
Clean up the checking of ENUMERATED and modernize the error reporting. Also eliminate the unused constraints argument for check_enumerated().
2015-01-12BER: Fix ENUMERATED with negative valuesBjörn Gustavsson
The ASN.1 compiler would go into an infinite loop if a value in an ENUMERATED was negative.
2015-01-12Modernize error handling for illicit tagsBjörn Gustavsson
2015-01-12Modernize error handling for instatiation of parameterized typesBjörn Gustavsson
2015-01-12Clean up get_unique_fieldname/2Dan Gudmundsson
get_unique_fieldname/2 would throw an exception that *all* callers would catch and handle. Since all callers catch the exception, it is much easier to return a special return value. Also use the new error reporting style. While we are at it, remove all catches of {asn1,Error} which are no longer thrown.
2015-01-12Clean up error reporting for duplicate tagsDan Gudmundsson
Split the test case duplicate_tags/1 into two parts. Do the error checking test in error_SUITE. Keep the SeqOptional2 specification and compile it from the per/1 and ber_other/1 test cases (for coverage).
2015-01-12asn1: Rewrite error handling for EXPORT to new styleDan Gudmundsson
2015-01-12asn1: Fix error reporting for the EXTERNAL typeDan Gudmundsson
Change to new error handling system and cover with tests.
2015-01-12asn1: Fix import checking codeDan Gudmundsson
All errors were not reported. Furthermore, get_referenced_type/2 will report errors if any module is missing, so the attempt to report additional errors in chained_import/4 would not find any errors.
2015-01-12Rewrite constraint handlingBjörn Gustavsson
The internal representation for constraints (and object sets) as produced by the parser was awkward, making further processing convoluted. Here follows some examples of the old representation for INTEGER constraints. The constraint 1..2 is represented as: {'ValueRange',{1,2}} If we extend the constraint like this: 1..2, ..., or like this: 1..2, ..., 3 the representation would be: {{'ValueRange',{1,2}},[]} and {{'ValueRange',{1,2}},{'SingleValue',3}} respectively. Note that the pattern {A,B} will match all these constraints. When combining constraints using set operators: 1..2 | 3..4 ^ 5..6 the representation will no longer be a tuple but a list: [{'ValueRange',{1..2}} union {'ValueRange',{3..4}} intersection {'ValueRange',{5..6}}] The parse has full knowledge of the operator precedence; unfortunately, the following pass (asn1ct_check) must also have the same knowledge in order to correctly evaluate the constraints. If we would change the order of the evaulation with round brackets: (1..2 | 3..4) ^ 5..6 there would be a nested listed in the representation: [[{'ValueRange',{1..2}} union {'ValueRange',{3..4}}] intersection {'ValueRange',{5..6}}] We will change the representation to make it more explicit. At the outer level, a constraint is always represented as {element_set,Root,Extension} Extension will be 'none' if there is no extension, and 'empty' if there is an empty extension. Root may also be 'empty' in an object set if there are no objects in the root. Thus the constraints: 1..2 1..2, ... 1..2, ..., 3 will be represented as: {element_set,{'ValueRange',{1,2}},none} {element_set,{'ValueRange',{1,2}},empty} {element_set,{'ValueRange',{1,2}},{'SingleValue',3}} We will change the set operators too. This constraint: 1..2 | 3..4 ^ 5..6 will be represented as: {element_set, {union, {'ValueRange',{1,2}}, {intersection, {'ValueRange',{3,4}}, {'ValueRange',{5,6}}}, none}} which is trivial to understand and evaluate. Similarly: (1..2 | 3..4) ^ 5..6 will be represented as: {element_set, {intersection, {union,{'ValueRange',{1,2}},{'ValueRange',{3,4}}}, {'ValueRange',{5,6}}}, none}
2015-01-12Strengthen the constraint_equivalence test caseBjörn Gustavsson
Instead of only compiling to the abstract format using 'abs', also compile to each of the back-ends.
2015-01-12Get rid of the test case for warnings_as_errorsBjörn Gustavsson
The warnings in the ASN.1 are being eliminated one by one and replaced with errors. Therefore, it is no longer possible to test warnings_as_errors. We will reimplement this test case in the future if we will introduce some new sensible warnings.
2015-01-12asn1ct_constructed_per: Remove useless argument 'NeedRest'Björn Gustavsson
NeedRest was introduced in df7bb30f, for unknown reasons (my guess is that the argument was needed at some point during the development of the commit). Found by dialyzer.
2015-01-12Add the other PKCS files to the rfcs test caseDan Gudmundsson
Changed the following from the original copies: PKCS-5 (renamed from PKCS-v21) PKCS-9 Import from CryptographicMessageSyntax-2009 instead of CryptographicMessageSyntax Since most of the files from the x420 directory are needed, copy all of them into the rfcs directory and remove the x420 directory and test case. Copy the test of OTP-7759 to the testRfcs test case.
2015-01-12asn1: Minor bug fixesDan Gudmundsson
Fixes needed to avoid a compiling asn1 files in order. For example the x420 directory in test now compiles with erlc *.asn Do not save class records without module information in asn1db files. Use recursive get_referenced_type in get_objclass_fields/2
2015-01-12Clean up checking of object setsBjörn Gustavsson
2015-01-12Fix several levels of inlined definitionsBjörn Gustavsson
2015-01-12Rewrite handling of ObjectSetFromObjectsBjörn Gustavsson
The ObjectSetFromObjects construct is implemented using the object_set_from_objects() function, which is similar to get_fieldname_element(). Rewrite the ObjectSetFromObjects handling to use get_fieldname_element() to share more code.
2015-01-12Clean up handling ObjectClassFieldTypeBjörn Gustavsson
2015-01-12Clean up and correct table constraint handlingBjörn Gustavsson
2015-01-12Correct another bug with instantiated typesBjörn Gustavsson
a1260b2ffa60581ce3af0728320b593cca3fd7b0 fixed a problem with expansion of parameterized types, but it didn't go all the way. The compiler would still crash if we attempted to define a value using the instantiated type.
2015-01-12Clean up matching of parametersBjörn Gustavsson
Introduce match_parameter/2 for matching a single parameter and match_parameters/2 for matching all of them.
2015-01-12Clean up handling of 'simpletable' and 'componentrelation'Björn Gustavsson
The constraint_member/2 function is used for looking up 'simpletable' and 'componentrelation' constraints. Both parts of its name are misleading. The "constraint" part makes you think that it is a general function for constraints, but it is not - it can only search for 'simpletable' and 'componentrelation'. The "member" part makes you think that it would return a boolean, but it returns either {true,Tuple} or false, making it more similar to lists:keysearch/3. Use lists:keyfind/3 (or lists:keymember/3) instead of constraint_member/2. Also use lists:keyfind/3 in one place where there was a direct matching of a 'simpletable' constraint.
2015-01-12Fix instantiation of an inlined type in a value definitionBjörn Gustavsson
2015-01-12Simplify and correct tag handlingBjörn Gustavsson
There is no reason to handle tags differently depending on the back-end. The PER back-end will simply ignore tags. There is also a bug in tags the ABSTRACT-SYNTAX and TYPE-IDENTIFIER pre-defined classes. So far it has not caused problems, but it could do in a future commit, such as the next commit...
2015-01-12Clean up constraint checkingBjörn Gustavsson
2015-01-12Use recursive get_referenced_type to get classdef directlyDan Gudmundsson
To be sure that indirect references to classes are solved.
2015-01-12Fix recursive get_referenced_typeDan Gudmundsson
2015-01-12Remove special case in parserBjörn Gustavsson
The parser handled the builtin ABSTRACT-SYNTAX and TYPE-IDENTIFIER classes specially, which caused problems. It turns out that there is no longer any need to handle those classes specially.
2015-01-12Improve handling of BIT STRING valuesBjörn Gustavsson
2015-01-12Check more errors in the simplified syntaxBjörn Gustavsson
An optional group must not contain mandatory class fields. All mandatory fields must be included in the simplified syntax.
2015-01-12Add the rfcs test caseBjörn Gustavsson
Add the ASN.1 specs from RFC-5911 and RFC-5912.
2015-01-12Handle CLASS.&field when checking valuesBjörn Gustavsson
2015-01-12Clean up and correct validation of OBJECT IDENTIFIER/RELATIVE-OIDDan Gudmundsson
Besides simplifying the code and doing better error checking and error reporting, fix the following bugs: Support retrieving an OBJECT IDENTIFIER/RELATIVE-OID from an object. Example: oid OBJECT IDENTIFIER ::= some-object.&some-field Allow an integer constant first in an OBJECT IDENTIFIER: integer INTEGER ::= 0 oid OBJECT IDENTIFIER ::= {integer 1}
2015-01-12Fix object set duplication testBjörn Gustavsson
Wrong fields in the record where checked when sorting, which caused duplicate objects to exist in constructed object sets and later caused an error.
2015-01-12per/uper: Fix code generation for nested types in objectsBjörn Gustavsson
2015-01-12Clean up use of asn1ct_gen:gen_types()Björn Gustavsson
asn1ct_gen:gen_types/3 is called by gen_encode_constructed/4 and generates encode *and* decode functions for any nested types. To faciliate future rewriting, where we might want to tweak code generation for encode and decode separately, refactor the code so that gen_encode_constructed/4 will only encode functions for nested types, and gen_deccode_constructed/4 will generate decode functions for nested types.
2015-01-12Correct recursion in OCTET STRING value definitionsBjörn Gustavsson
2015-01-12Fix BER code generationDan Gudmundsson
PKIX1Explicit-2009 did not compile.
2015-01-12Clean up get_fieldname_element/3Björn Gustavsson
Also add proper error handling.
2015-01-12Provide more reliable location of errorsBjörn Gustavsson
File names and line number information was not reliable available when producing error messages. Some items have embedded line number information, and sometimes the S#state.type and/or S#state.value could be used to retrieve the line number information. To make sure that we can always retrieve at least an approximate error location, store the top-level construct being checked in S#state.error_context. Example of top-level constructs: Seq ::= SEQUENCE {...} i INTEGER ::= 42 This is a short-term solution. In the long term, we would want the parser to include line number information in all items.
