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).
2013-09-18asn1_test_lib: Add roundtrip functions and use them everywhereBjörn Gustavsson
Even if the roundtrip functions are very simply, putting them here makes it possible to change its behavior in one place (e.g. if we are to change encode and decode not to wrap the result in a ok tuple in some future release).
2013-08-30PER, UPER: Optimize encoding using an intermediate formatBjörn Gustavsson
There are some minor incompatibilities for BIT STRING: {bit,Position} is now only only supported for a named BIT STRING type. Values longer than the maximum size for the BIT STRING type would be truncated silently - they now cause an exception.

2013-05-31PER: Fix aligments bugs for short stringsBjörn Gustavsson
The encoder wrongly assumed that a known multiplier string (such as IA5String) encoded as exactly 16 bits did not need to be aligned to an octet boundary. X.691 (07/2002) 27.5.7 says that it does. Since an OCTET STRING encoded to 16 bits (two octets) should not be aligned to an octet boundary, that means that asnct_imm:dec_string() needs an additional parameter to determine whether a string of a given length needs to be aligned. Furthermore, there is another subtle rule difference: An OCTET STRING which does not have fixed length is always aligned (in PER), but a known multiplier string is aligned if its upper bound is greater than or equal to 16. In encoding, make sure that short known multiplier strings and OCTET STRINGs with extensible sizes are not aligned when they are below the appropriate limit.

2013-01-23By default, encode BIT STRING to bitstringsBjörn Gustavsson
Add the option 'legacy_bit_string' to decode to the old list format.

2012-12-06Optimize decoding of OCTET STRINGsBjörn Gustavsson
Decoding of fragmented OCTET STRINGs was only implemented when the size was constrained to a single value. While at it, support decoding fragmented OCTET STRINGS in all circumstances.
2012-12-06testPrimString: Increase readability by introducing a roundtrip functionBjörn Gustavsson
Reduce verbosity and introduce readability by introducing the roundtrip/2 function. That will help us to do future extensions to this test suite.

2010-03-11asn1 tests: Don't refer to $ERL_TOP in compiler optionsBjörn Gustavsson
On Windows, $ERL_TOP contains a cygwin-style pathname that can be used in Makefiles to (for instance) include other Makefiles, but must not be passed to non-cygwin programs such as "erlc". Therefore, using compiler options such as "-I $(ERL_TOP)/lib/test_server/include" will not work on Windows. Fix this problem by include "test_server.hrl" using -include_lib() instead of -include(). That works because -include_lib() searches for include files in the code path without the need for any -I options.
