2014-02-21Deprecate asn1 functionsBjörn Gustavsson
Those asn1 functions are no longer needed because they all have better alternatives.

2014-02-18Fix library application appup filesTobias Schlager
As discussed in issue #240 *all* OTP library applications use the '.*' wildcard as up and down version. This makes library applications always up- and downgradeable. Using the wildcard version obsoletes all maintenance tasks regarding library applications' appup files. Additionally, it prevents upgrade problems caused by automatically included application dependencies when using reltool to create releases. Missing copyright headers are now consistently present.
2014-02-13Correct subtyping of extensible ENUMERATEDBjörn Gustavsson
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. Reported-by: Morten Nygaard Åsnes
2014-01-31asn1ct_check: Use a return value to silence a dialyzer warningBjörn Gustavsson
Unfortunately the code in question is not covered by our test suites, but it should be correct to do the same thing as in the clause above.
2014-01-31asn1ct_check: Remove useless call to check_integer/3Björn Gustavsson
check_integer/3 can check nothing for an INTEGER without any named values. Remove the useless call to silence a dialyzer warning for unmatched return.
2014-01-31asn1ct_check: Correct error handling for illegal OCTET STRING valuesBjörn Gustavsson
The value for an OCTET STRING must be specified as either a bstring or an hstring. Everything else (including character strings) is illegal. This correction also removes the offending code that caused an unmatched return warning from dialyzer.
2014-01-31asn1ct: Silence dialyzer warnings for unmatched returnsBjörn Gustavsson
2014-01-31asn1ct_table: Remove unused flexibility in table creationBjörn Gustavsson
Unused flexibility complicates the code and can hide bugs. new/1 is never called with a table name that already exists, so we should remove the code that allows for that. That will increase the coverage of asn1ct_table to 100%. Also remove the new/2 and new_reuse/2 functions which are never called externally.
2014-01-31asn1ct_table: Silence a dialyzer warning for unmatched returnBjörn Gustavsson
Change the code so that delete/1 always returns 'true'. While at it, also remove the TODO comment and explain in a comment why we want to keep the delete/1 function.
2014-01-31asn1ct_gen: Silence dialyzer warnings for unmatched returnsBjörn Gustavsson
2014-01-31asn1ct_value: Silence a dialyzer warning for unmatched returnBjörn Gustavsson
2014-01-31asn1ct_tok: Check return value from file:close/1Björn Gustavsson
This will silence a dialyzer warning for unmatched return.

2014-01-20Optimize code surrounding calls to complete/1Björn Gustavsson
complete/1 is used when encoding open types (as well as in the encode/2 function in a generated module). The use of complete/1 for encoding open types used to be optimized in two different places. One place was in the alignment optimization pass, where we attempted to replace the call to complete/1 with a call to iolist_to_binary/1. That optimization was taken out in a previous commit that introduced the {list,_,_} intermediate instruction. The other place was when creating the intermediate representation for the encoding of the open type. When attempting to wrap primitive types in an open type, we would attempt to optimize the encoding of the length decscriptor. We will remove that optimization in this commit. Since the previous two optimizations did not optimize encoding of open types as much as we would want, we will introduce a new optimization in a separate pass that will go further than the previous optimizations.
2014-01-20asn1ct_imm: Add the intermediate instruction {list,List,Dst}Björn Gustavsson
The {list,List,Dst} instruction gives us as general way to capture the building of something into a variable. That will make inlining of intermediate code much easier. It also allows us to eliminate the versions of the apply, call_gen, and cond instructions that takes a target variable. Also remove the optimization in the alignment optimization pass that attempts to replace calls to complete/1 with calls to iolist_to_binary/1. That optimization will not work anymore without rewriting, so we will remove it in this commit and introcude a more powerful optimization in a future commit.
2014-01-20Generate intermediate code that is easier to optimizeBjörn Gustavsson
Instead of generating: {assign,Dst,"element(2, Val)"} generate: {call,erlang,element,[2,{var,"Val"}],Dst} The latter expression is easier to understand since there is no need to parse a string which may contain an arbitrary expression. While at it, also discontinue the practice to treat "naked" atoms as variables. A variable must always be given as {var,String}.
2014-01-20asn1ct_imm: Add the {set,{var,Src},{var,Dst}} instructionBjörn Gustavsson
The {assign,Dst,Src} instruction is difficult to cope with when doing advanced optimizations, since its source argument is a string which may contain any expression. Instead of changing how {assign,_,_} works, we will introduce new instructions that can be used instead of {assign,_}, and remove {assign,_,_} in a later commit when it is no longer used. The first new instruction we will introduce is: {set,{var,Src},{var,Dst}} It is useful for common sub-expression elemination among other things. For the moment, we will only allow a variable as a source argument, but we could extend it in the future to allow constants as well.
2014-01-20Keep type information in the apply intermediate instructionBjörn Gustavsson
To facilitate inlining of apply calls in the intermediate format.
2014-01-20asn1ct_imm: Add a field for intermediate code for call_genBjörn Gustavsson
It will greatly facilitate further optimizations if we include the intermediate code (if available) in the call_gen tuple.

2014-01-20Improve construction of {cons,H,T} instructionsBjörn Gustavsson
Make sure that we don't construct: {cons,{integer,I},{cons,{binary,B},T}} - OR - {cons,{binary,B},{cons,{integer,I},T}} but: {cons,{binary,[{put_bits,I,8,[1]}|B]},T} - OR - {cons,{binary,B++[{put_bits,I,8,[1]}]},T}
2014-01-20Teach asn1ct_func:call_gen/4 to quote the generated function nameBjörn Gustavsson
The function name could contain hyphens or other characters not allowed in non-quoted function names.

2013-10-17Fix complicated union of INTEGER constraintsBjörn Gustavsson
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.
2013-10-01Fix broken handling of default values for BIT STRINGsBjörn Gustavsson
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).
2013-09-30Cope with .erlang files that print to stdoutBjörn Gustavsson
Don't redirect standard output when auto-generating the asn1ct_rtt.erl and asn1ct_eval*.erl source files, because anything printed form .erlang will end up in them, probably causing a compilation error.
2013-09-30PER/UPER: Correct encoding for single-value extensible constraintsBjörn Gustavsson
An extensible constraint which is a union of single values, such as: INTEGER (1|17, ...) would be incorrectly encoded.
2013-09-30asn1ct_value: Handle named INTEGERs with constraintsBjörn Gustavsson
The asn1ct:value/2 function would crash for name INTEGERs with constraints, such as INTEGER {a(2),b(3),z(17)} (2|3|17, ...).

* maint: Teach the ASN.1 compiler the no_ok_wrapper option Optimize the generated decode/2 function
2013-09-27Teach the ASN.1 compiler the no_ok_wrapper optionBjörn Gustavsson
Add the no_ok_wrapper option so that the generated M:encode/2 and M:decode/2 functions will not wrap a successful return value in an {ok,...} tuple. Errors will cause exceptions. Eliminating the wrapping tuple allows simpler nesting of calls.
2013-09-27Optimize the generated decode/2 functionBjörn Gustavsson
Use 'try' instead of 'catch', and don't match anything that cannot actually be returned from the generated encoding code.
