Own Id: OTP-9062

Shut off some dialyzer warnings

Own Id: OTP-9063

Crash in asn1ct_check, componentrelation_leadingattr fixed. (Thanks to Stephane Pamelard for finding the bug)

Own Id: OTP-9092

The encoding of ExtensionAdditionGroup (for PER and UPER) is corrected.

Own Id: OTP-8866 Aux Id: OTP-8797, SEQ-11557

A race condition when several processes in parallel start to do encode/decode using the driver could cause an error log regarding crashing port owner process. This race is now eliminated.

Own Id: OTP-8948 Aux Id: seq11733

Extension Addition Groups are now supported by the parser and in all backends.

Own Id: OTP-8598 Aux Id: seq-11557

Extension Addition Groups are now supported in nested types within a SEQUENCE and CHOICE as well (missed that in previous fix)

Own Id: OTP-8797 Aux Id: seq-11557

Bug in UNALIGNED PER regarding encoding and decoding of constrained numbers with a valuerange > 1024. (Thanks to Vincent de Phily)

Own Id: OTP-8779

Minor corrections in the User Guide.

Own Id: OTP-8829

By default, the ASN.1 compiler is now silent in the absence of warnings or errors. The new 'verbose' option or the '-v' option for erlc can be given to show extra information (for instance, about the files that are generated). (Thanks to Tuncer Ayaz.)

Own Id: OTP-8565

Harmless buffer overflow by one byte in asn1 and ram_file_drv.

Own Id: OTP-8451

Cross compilation improvements and other build system improvements.

Most notable:

(Thanks to Henrik Riomar for suggestions and testing)

(Thanks to Winston Smith for the AVR32-Linux cross configuration and testing)

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-8323

Add support for prefixing macro names generated by the compiler

This is useful when multiple protocols that contains macros with identical names are included in a single module.

Add the missing record_name_prefix compiler option to the documentation.

Own Id: OTP-8453

Cleanups suggested by tidier and modernization of types and specs.

Own Id: OTP-8455

Support for EXTENSIBILITY IMPLIED and SET/SEQ OF NamedType is added.

Own Id: OTP-8463

The documentation is now built with open source tools (xsltproc and fop) that exists on most platforms. One visible change is that the frames are removed.

Own Id: OTP-8256

A new option {n2n,TypeName} can be used to enable generation of conversion functions from name to number and vice versa for selected ENUMERATION types. The option can be repeated many times in order to specify several types in the same file.
If the TypeName specified does not exists or is not an ENUMERATION type, the compilation will be terminated with an error code.
Below follows an example on how to use the option from the command line with erlc:
erlc -bper_bin +optimize +driver +"{n2n,'CauseMisc'}" +"{n2n,'CausePcl'}" MyModyle.asn

Own Id: OTP-8136 Aux Id: seq11347

Range checks added for BIT STRING with fixed SIZE constraint.

Own Id: OTP-7972 Aux Id: seq11280

Now support multiple-line comments in asn1-specs as specified in ASN1 X.680 (07/2002), section 11.6.4

Own Id: OTP-8043

Now parses and adds abstract syntax for PATTERN subtype constraint. No other action is taken on this type of constraint.

Own Id: OTP-8046

The ASN1 subtype constraint CONTAINING Type, CONTAINING Type ENCODED BY Value and ENCODED BY Value now is parsed. Abstract syntax is added but no further action in generated code is taken.

Own Id: OTP-8047

A faulty receive case that catch-ed all messages in the initialization of the driver has been removed, the initialization has been restructured.

Own Id: OTP-7954 Aux Id: seq11220

The anonymous part of the decode that splits the ASN1 TLV into Tag Value tuples has been optimized.

Own Id: OTP-7953

Error that caused crash when drivers were loaded is now corrected. Parallel driver for asn1 now enabled.

Own Id: OTP-7904 Aux Id: seq11220

Optimized code for ENUMERATION type in encoder/decoder.

Own Id: OTP-7909

Removed parallel-driver functionality due to failure when loading the driver.

Own Id: OTP-7900 Aux Id: seq11220

Generated code now uses guards that is not obsolete, e.g. is_integer/1 instead of integer/1.

Own Id: OTP-7910

A BIT STRING with a size constraint that has a single value and an extension as in BIT STRING (SIZE (16,...)) was erroneous encoded/decoded. This is now corrected and follows X.691 Section 15.6.

Own Id: OTP-7876 Aux Id: seq11220

Now asn1 starts multiple drivers to enable simultaneous encode/decode in different processes for the asn1-backends using linked-in driver.

Own Id: OTP-7801

Decode of an open_type when the value was empty tagged type encoded with indefinite length failed. This is now corrected.

Own Id: OTP-7759 Aux Id: seq11166

Encode of BIT STRING with size of exact length, on compact_bit_string format in UNALIGNED PER failed when value had the right size, i.e. no padding needed.

Own Id: OTP-7763 Aux Id: seq11182

For a BIT STRING with SIZE constraint higher than 255 compiled with [per_bin,optimize, compact_bit_string] an improper io-list was created and sent to the c-driver for complete encoding. This error has been resolved.

Own Id: OTP-7734 Aux Id: seq11170

A a SEQUENCE OF with a type that is a CHOICE with ellipses occurred falsely a compile error. The error causing that is now removed.

Own Id: OTP-7708 Aux Id: seq11136

constrained number with a value-range greater than 512 now has the proper interpretation of the values that causes shift to the next number of units (bits), According to limit condition 2^m < "range" =< 2^(m + 1) then the number of bits are m + 1.

Own Id: OTP-7681 Aux Id: seq11114

Can now handle default values of simple types that is provided on its own format, i.e. not just as asn1_DEFAULT.

Own Id: OTP-7678 Aux Id: seq11114

comparison of two value definitions failed due to new module name field in valuedef record. It is now corrected.

Own Id: OTP-7608

Bug regarding propagation of parameters of parameterized type fixed.

Own Id: OTP-7174 Aux Id: seq10864

A bug, related to instantiation of a parameterized type with a type definition in the parameter-list, has been removed. The definition of the parameter type was in another module than the instance definition causing limited module info.

Own Id: OTP-7299 Aux Id: seq10864

Removed hard-coded name that may cause name collision.

Own Id: OTP-7322 Aux Id: seq10864

Object set of a class with id with properties UNIQUE OPTIONAL and the id field is lacking in the object is for now treated as a object without a unique identifier, i.e. no table is generated for this object.

Own Id: OTP-7332 Aux Id: seq10864

Compiler crashed when failed to handle a OID as ValueFromObject.

Own Id: OTP-7476 Aux Id: seq10999

A corrupted encoding may cause a loop when a buffer of at least two bytes of zero matches tag and length of a SET component. This behavior occurred only with decoder generated with ber or ber_bin options. Now a control breaks the loop.

Own Id: OTP-7533

Encode of BIT STRING longer than 255 bits with a SIZE(integer()) constraint caused a crash when spec was compiled with per_bin, optimize options.

Own Id: OTP-7602 Aux Id: seq11079

Now supports REAL type of base 2 and 10

Own Id: OTP-7166 Aux Id: seq10864

By the asn1 compiler option {record_name_prefix Name} a prefix is chosen to the name of the record generated in the .hrl and used in the generated .erl files.

Own Id: OTP-7204 Aux Id: seq10853

The TypeFromObject production now covered

Own Id: OTP-7295 Aux Id: seq10468

Extended support for ObjectSetFromObjects. Production occurred as a part of the RootElementSetSpec of the ObjectSetSpec. Added also support for Exclusion of Element in ObjectSetSpec.

Own Id: OTP-7306 Aux Id: seq10864

Now implements RELATIVE-OID

Own Id: OTP-7334 Aux Id: seq10864

Now is ordering, according to the canonical order, of components in a SET added. Canonical order is described in X.691 9.2 and X.680 8.6

Own Id: OTP-7375 Aux Id: unaligned PER

The precedence rules for extended constraints have been misinterpreted. The rule says for instance that if there are more than one constraint on a type that have extension-mark, only the last of the extension-marks would be kept. This affects the encoding of PER and is now corrected.

Own Id: OTP-7400 Aux Id: OTP-7335

A constrained number with a single-value constraint that is extensible was falsely encoded/decoded in aligned/unaligned PER. This is now corrected.

Own Id: OTP-7403

The ASN.1 compiler has got a new backend supporting PER UNALIGNED. Previously it was only support for PER ALIGNED.

Own Id: OTP-7335

Now the asn1-compiler handles unions and intersections of PermittedAlphabet constraints.

Own Id: OTP-7374 Aux Id: unaligned PER

With the undocumented option no_final_padding the whole encoded message is not padded to a border of a byte. Thus the returned encoded message is a bitstring.

Own Id: OTP-7407

When duplicates of object fields were removed only one table access function for each unique identifier value was generated. This can occur when several object sets are merged by use of ObjectSetFromObjects.

Own Id: OTP-7263 Aux Id: seq10864

DER: For some complex types and components with reference to type in several steps the default value check function was not generated. This is now fixed.

Own Id: OTP-7268 Aux Id: seq10684

Now is the tag in a tagged type as parameter propagated to the instance.

Own Id: OTP-7273 Aux Id: seq10864

Added type T61String that is similar to TeletexString

Own Id: OTP-7264 Aux Id: seq10864

A bug related to renaming of types has been fixed.This occurred using the .set.asn functionality.

Own Id: OTP-7149 Aux Id: seq10853

syntax error in ASN1 value now correctly shown

Own Id: OTP-7154 Aux Id: seq10864

Now a COMPONENTS OF construct in a parameterized type is expanded correctly

Own Id: OTP-7155 Aux Id: seq10864

Now the asn1-compiler also handles empty SEQUENCE DEFAULT values as {}.

Own Id: OTP-7169 Aux Id: seq10864

Now SelectionType gets the tag of the selected type.

Own Id: OTP-7171 Aux Id: seq10864

Correction of generated code for decode of an open type in a SEQUECNE OF/ SET OF

Own Id: OTP-7193 Aux Id: seq10875

Misc improvements and bug corrections regarding default values.

Own Id: OTP-7199 Aux Id: seq10864

Now generating records in .hrl file for instances of parameterized SEQUENCE or SET.

Own Id: OTP-6835

Optimization using bitstr in encode/decode functions. Active with [per_bin, optimize] options.

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-6882

Parsing and encoding/decoding of type constrained with SIZE with extension is now recovered.

Own Id: OTP-6763

inline failed because trying to use a removed module.

Own Id: OTP-6769

Fixed problem with a reference to a type from an object. The failure was caused bye change of type name when using inline option.

Own Id: OTP-6770

Handling of decode pattern for exclusive decode was false in the case when an un-decoded component had more than one following elements that should be decoded.

Own Id: OTP-6786

Now the asn1-compiler supports two root lists in SEQUENCE and SET according to alternative three in ComponentTypeLists (X.680 07/2002 section 24.1), i.e. with an extension list between two ellipses.

Own Id: OTP-5067 Aux Id: seq8452

Merging modules by inline earlier disabled the driver (used in modules generated with [optimized]/[optimized,driver] options). Now this is repaired.

Own Id: OTP-6601

Checking phase now aware of which module an INSTANCE OF is declared in.

Own Id: OTP-6702

The compiler now handle all forms of ObjectSetSpec according to ITU-T recommendation X.681 (ISO/IEC 8824-2:2002).
