2016-01-21PER: Correct compilation of named INTEGERsBjörn Gustavsson
When a constrained INTEGER has more than 16536 values and named values, the compiler would crash when compiling to the PER format. Example: Longitude ::= INTEGER { oneMicrodegreeEast(10), oneMicrodegreeWest(-10), unavailable(1800000001) } (-1799999999..1800000001) Reported-by: Ingars

In most cases, we don't have to seed the random number generator, as the rand:uniform/1 takes care about that itself.

2015-03-17PER, UPER: Eliminate compiler warning for SeqPrim.asn1Björn Gustavsson
The BEAM compiler now warns more aggressively for expressions whose values are not used. For example, the generated Erlang code for the following ASN.1 code will now cause a warning: Seq ::= SEQUENCE { ..., os OCTET STRING (SIZE (17000..30000)) } The generated Erlang code looks similar to the following: Enc9@bin = iolist_to_binary(Enc9@output), Enc9@len = byte_size(Enc9@bin), [align|encode_fragmented(Enc9@bin, 8)] The variable Enc9@len is not used and the BEAM compiler will complain that the value returned from the byte_size/1 call is not used. Improve the optimization of the intermediate code to eliminate the assignment to the unused variable.

2015-01-12Reimplement storeindb/2 to avoid excessive process communicationBjörn Gustavsson
As currently implemented, there is one call to asn1db:dbget() and asn1db:dbput() for each type/value definitions in an ASN.1 specification. If we check for duplicate definitions locally, we can send all definitions in a single call.
2015-01-12Remove useless fields in #state{}Björn Gustavsson
Three fields ('type','value', and 'vname') are almost unused. They are set, but almost never read. Eliminate the last remaining uses and the fields themselves.

2015-01-12asn1ct_tok: Clean upBjörn Gustavsson
2015-01-12asn1ct_parser2: Remove expensive lookahead_assignment/1 functionBjörn Gustavsson
In the parsing of a value assignment, such as: value INTEGER ::= 42 there is call to a function called lookahead_assignment/1 that will ensure that the sequence of tokens that follows the value is a valid assignment. The problem is that if the next assignment is a value assignment, that too will look ahead to the next assignment. That means that the complexity will be quadratic if there are many value assignments following each other. The reason for the test in the first place is unclear; my guess is that it was an attempt to provide better error reporting.
2015-01-12asn1ct_parser2: Clean up error handling and reportingBjörn Gustavsson
Errors were reported using a throw like this: throw({asn1_error,{get_line(hd(Tokens)),get(asn1_module), [got,get_token(hd(Tokens)),expected,typereference]}}). The attempt to tell the user what was expected was often mis-leading. It is time-consuming and non-trival to provide correct information of what is expected. Therefore, we will not even try. Instead we will spend more effort to report the token where the error was discovered. We will replace each throw with a function call: parse_error(Tokens). Also add the syntax_SUITE test suite to test error reporting and to cover all error reporting code. Remove the old c_syntax/1 test case. Also remove all out-commented code.
2015-01-12asn1ct, asn1ct_parser2: Refactor the upper levels of error handlingBjörn Gustavsson
Responsibilities for parse error handling were split between asn1ct and asn1ct_parser2 in a confusing way. Let asn1ct_parser2 return structured_error tuples in the same way as the check pass.
2015-01-12asn1ct_parser2: Eliminate all uses of old-style 'catch'Björn Gustavsson
Most uses of 'catch' are not necessary. For example, parse_or/2 is typically called like this: case catch parse_or(Tokens, Flist) of {'EXIT',Reason} -> exit(Reason); {asn1_error,_}=AsnErr -> throw(AsnErr); Result -> Result end. Since {asn1_error,_} is always thrown (never returned) and a successful is always returned (never thrown), the 'case' and the 'catch' are not necessary. The code can be simplified too: parse_or(Tokens, Flist) In a few cases, we will need to replace the 'catch' with 'try'...'catch'.
2015-01-12asn1ct_parser2: Clean up parse_or/3 and parse_or_tag/3Björn Gustavsson
Use try...catch instead of catch.
2015-01-12asn1ct_parser2: Correct extraction of line number from tokenBjörn Gustavsson
The first position in a token tuple is always an atom, the second the line number. The code tested the third position.
2015-01-12asn1ct_parser2: Throw an {asn1_error,...} for *all* parse errorsBjörn Gustavsson
In a future commit, we want to tighten what we catch. Therefore, legitimate parsing errors should always throw a controlled exception, instead of arbitrarily crashing.
2015-01-12asn1ct_parser2: Simplify parse_Type/1Björn Gustavsson
The parse_Type/1 calls various type parse functions. Most of those functions return a #type record, but not all of them. If a #type{} record is not returned, parse_Type/1 will wrap the return value in a We can simplify the code in parse_Type/1 if we make sure that the type parsing functions called by parse_Type/1 always return a #type{} record.
2015-01-12asn1ct_parser2: Remove unsuccessful parsing of ValueSetFromObjectsBjörn Gustavsson
The TypeFromObject and ValueSetFromObjects grammar productions cannot be distinguished by the parser without the help of type information (which the parser does not have). Since the parser attempts to parse TypeFromObject before ValueSetFromObjects, the parsing of ValueSetFromObjects will always fail.
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.

2015-01-12BER: Fix ENUMERATED with negative valuesBjörn Gustavsson
The ASN.1 compiler would go into an infinite loop if a value in an ENUMERATED was negative.

2015-01-12Clean 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.
