There was a issue with BER encoding and the undec_rest option in generated decoders. An exception could be thrown instead of returning an error tuple.

Own Id: OTP-14786 Aux Id: ERL-518

The asn1ct:test functions crashed on decoders generated with options no_ok_wrapper, undec_rest.

Own Id: OTP-14787 Aux Id: ERL-518

Compiling an ASN.1 module using the option {n2n, EnumTypeName} when EnumTypeName contains a hypen like for example Cause-Misc caused syntax errors when compiling the generated Erlang code. This is now corrected.

Own Id: OTP-14495 Aux Id: ERL-437

Default values now work in extension for PER, so if you give the atom asn1_DEFAULT instead of a value it will become the default value.

Own Id: OTP-13011 Aux Id: ERIERL-60

Fixed compilation error of generated code caused by a missing quotation of function names as part of an external call for encoding.

Own Id: OTP-14519 Aux Id: ERIERL-49

Add compile option -compile(no_native) in modules with on_load directive which is not yet supported by HiPE.

Own Id: OTP-14316 Aux Id: PR-1390

The error tuple returned from the encode and decode functions will now include the stack backtrace to make it easier to understand what went wrong.

Own Id: OTP-13961

The deprecated module asn1rt has been removed. The deprecated functions asn1ct:encode/3 and asn1ct:decode/3 have been removed. The undocumented function asn1ct:encode/2 has been removed.

Compiling multiple ASN.1 modules in the same directory with parallel make (make -j) should now be safe.

Own Id: OTP-13624

Internal changes

Own Id: OTP-13551

When compiling to the PER format, the ASN.1 compiler would crash when attempting to compile an ASN.1 module with a constrained INTEGER with more than 65536 values and named values. (Thanks to Ingars for reporting this bug.)

Own Id: OTP-13257

The ASN.1 compiler will now emit Dialyzer suppressions for improper lists. Thus, there is no longer any need to use --Wno_improper_lists when analyzing modules generated by the ASN.1 compiler.

Own Id: OTP-13324

Trying to encode an empty named BIT STRING in BER would fail with a function_clause exception. (Thanks to Svilen Ivanov for reporting this bug.)

Own Id: OTP-13149

Many bugs have been eliminated in the the ASN.1 compiler so that it can now successfully compile many more ASN.1 specifications. Error messages have also been improved.

Own Id: OTP-12395

The documentation for asn1ct:test/1,2,3 and asn1ct:value/2 has been updated with information about the limitations of the functions.

Own Id: OTP-12765 Aux Id: seq12866, seq12867

The ASN.1 compiler would crash if a SEQUENCE ended with a double set of ellipses (...).

Own Id: OTP-12546 Aux Id: seq12815

When decoding BER, primitives with an indefinite length will be immediately rejected. (Thanks to Simon Cornish for reporting this bug.)

Own Id: OTP-12205

BER: A bug with compliance to X.680 (200811) s31.2.7 has been fixed. Basically, when TagDefault is AUTOMATIC then tags are IMPLICIT unless EXPLICIT is given.

Own Id: OTP-12318

Usage of the EXTERNAL 1994 variant type was broken.

Own Id: OTP-12326

Several problems where the ASN.1 compiler would crash when attempting to compile correct specifications have been corrected.

Own Id: OTP-12125

Robustness when decoding incorrect BER messages has been improved.

Own Id: OTP-12145

The ASN.1 compiler now generates code that don't trigger Dialyzer warnings. Along the way, a few minor bugs were fixed.

Own Id: OTP-11372 Aux Id: seq12397

Subtyping an extensible ENUMERATED would cause an compilation error. (Thanks to Morten Nygaard Åsnes for reporting this bug.)

Own Id: OTP-11700

When specifying the value for an OCTET STRING in a specification, the ASN.1 standard clearly states that the value must be either a bstring or an hstring, but NOT a cstring. The ASN.1 compiler will now generate a compilation error if the value of an OCTET STRING is given as a character string.

That is, the following example is now illegal:

string OCTET STRING ::= "Now illegal"

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-11727

Application upgrade (appup) files are corrected for the following applications:

asn1, common_test, compiler, crypto, debugger, dialyzer, edoc, eldap, erl_docgen, et, eunit, gs, hipe, inets, observer, odbc, os_mon, otp_mibs, parsetools, percept, public_key, reltool, runtime_tools, ssh, syntax_tools, test_server, tools, typer, webtool, wx, xmerl

A new test utility for testing appup files is added to test_server. This is now used by most applications in OTP.

(Thanks to Tobias Schlager)

Own Id: OTP-11744

By giving --enable-static-{nifs,drivers} to configure it is now possible to statically linking of nifs and drivers to the main Erlang VM binary. At the moment only the asn1 and crypto nifs of the Erlang/OTP nifs and drivers have been prepared to be statically linked. For more details see the Installation Guide in the System documentation.

Own Id: OTP-11258

Code generation for the per and uper backends has been somewhat improved.

Own Id: OTP-11573

The OCTET STRING and BIT STRING types now have a more natural mapping to Erlang types (binary and bitstring, respectively), which is more efficient and will avoid useless conversions between lists and binaries/bitstrings.

This is an incompatible change. To revert to the old mapping to support existing applications, use the legacy_erlang_types option.

Impact: There is a potential for better performance, as it is now possible to avoid conversions between lists and binaries both in the generated ASN.1 encode/decode code and in the application itself.

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-11594

All functions in the asn1rt module, as well as asn1ct:decode/3 and asn1ct:encode/3, are now deprecated.

Own Id: OTP-11731

Generated .hrl files are now protected from being included more than once.

Own Id: OTP-11804

The default value for a BIT STRING would not always be recognized, causing the encoding to be incorrect for the DER/PER/UPER encodings.

Own Id: OTP-11319

The ASN.1 application would fail to build if the .erlang file printed something to standard output.

Own Id: OTP-11360

An union of integer ranges in an INTEGER constraint could sometimes be interpreted as the intersection of the range.

Own Id: OTP-11411 Aux Id: seq12443

Extensible, multiple single value constraints (such as INTEGER (1|17, ...)) would be incorrectly encoded.

Own Id: OTP-11415

The ASN.1 compiler would fail to compile a constraint with values given for for the extension part (such as INTEGER (1..10, ..., 11..20)).

Own Id: OTP-11504

The new option 'no_ok_wrapper' generates M:encode/2 and M:decode/2 functions that don't wrap the return value in an {ok,...} tuple.

Own Id: OTP-11314

Open types greater than 16383 bytes will now be correctly encoded and decoded.

Own Id: OTP-11262 Aux Id: seq12386, OTP-11223

For the PER and UPER formats, code generation especially for encoding has been improved.

When encoding BIT STRINGs, values longer than the maximum size for the BIT STRING type would be truncated silently - they now cause an exception.

Open types greater than 16383 bytes will now be correctly encoded and decoded.

IMPORTANT NOTE: For ASN.1 specifications that depend on each other, such as the S1AP-* specifications, it is important to recompile all specifications (compiling some with this version of the compiler and some with an older version will not work).

Own Id: OTP-11300

Fix some Makefile rules that didn't support silent rules. Thanks to Anthony Ramine.

Own Id: OTP-11111

PER/UPER: A semi-constrained INTEGER with a non-zero lower bound would be incorrectly decoded. This bug was introduced in R16.

PER/UPER: Given INTEGER (10..MAX, ...), attempting to decode any integer below 10 would cause the encoder to enter an infinite loop.

PER/UPER: For a type with an extensible SIZE constraint, sizes outside of the root range were incorrectly encoded.

Given a constraint such as (SIZE (5, ...)), encoding a size less than 5 would fail (PER/UPER). Similarly, for BER decoding would fail.

PER: The encoder did not align a known multiplier string (such as IA5String) of length 16 bits (exactly) to an octet boundary.

In rare circumstances, DEFAULT values for the UPER backend could be wrongly encoded.

Own Id: OTP-11134

UPER: The compiler would crash when compiling an ENUMERATED having more than 63 extended values.

PER/UPER: A SEQUENCE with more 64 extended values could not be decoded.

Own Id: OTP-11153

When decoding a SEQUENCE defined inline inside a an extension addition group, the record named generated by the decoding code would not match the name in the generated .hrl file.

Own Id: OTP-11154 Aux Id: seq12339

Postscript files no longer needed for the generation of PDF files have been removed.

Own Id: OTP-11016

When an object set is an actual parameter, the extension marker for the object set could get lost (which would cause the decoding of unknown values to fail).

Own Id: OTP-10995 Aux Id: seq12290

The generated decoder for the 'per' and 'uper' backends did not correctly decode ENUMERATEDs with a single value.

The generated encoder for the 'per' and 'uper' backends generated an empty binary for a top-level type that did not need to be encoded (such as an ENUMERATED with a single value). The correct result should be a binary containing a 0 byte.

Own Id: OTP-10916 Aux Id: seq12270

Fixed broken table constraints within a SET OF or SEQUENCE OF for the BER backend.

Own Id: OTP-10853 Aux Id: seq12245

Encoding SEQUENCEs with multiple extension addition groups with optional values could fail (depending both on the specification and whether all values were provided).

Own Id: OTP-10664

The options for the ASN.1 compiler has been drastically simplified. The backend is chosen by using ber, per, or uper. The options optimize, nif, and driver are no longer needed. The old options will still work, but will issue a warning.

Another change is that generated encode/2 function will always return a binary (some backends used to return an iolist).

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-10410 Aux Id: kunagi-254 [165]

The ASN.1 compiler generates faster decode functions for PER and UPER. Some minor improvements have also been made for PER/UPER encoding, and to the BER backend.

Own Id: OTP-10519 Aux Id: kunagi-322 [233]

The ASN.1 compiler will now always include necessary run-time functions in the generated Erlang modules (except for asn1rt_nif which is still neeeded). If the option 'inline' is used the ASN.1 compiler will generate a warning. But if '{inline,OutputFile}' is use, the ASN.1 compiler will refuse to compile the file. (Use a .set.asn file if you need to remove the output file.)

The 'BIT STRING' type will now be decoded as Erlang bitstrings by default. Use the new legacy_bit_string option to encode as lists of ones and zeroes. (The compact_bit_string option still works as before.)

Open types are now always returned as binaries (when there is no information allowing them to be decoded).

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-10588 Aux Id: kunagi-341 [252]

ASN.1 decoders generated with the options -bber_bin +optimize +nif would decode open types with a size larger than 511 incorrectly. That bug could cause decoding by public_key to fail. The bug was in the NIF library asn1_erl_nif.so; therefore there is no need re-compile ASN.1 specifications that had the problem.

Own Id: OTP-10805 Aux Id: seq12244

Encoding SEQUENCEs with multiple extension addition groups with optional values could fail (depending both on the specification and whether all values were provided).

Own Id: OTP-10811 Aux Id: OTP-10664

Encoding and decoding of integer ranges can now be done with an upper bound larger than the previous limit of 16^10. The new upper bound in per encoding and decodings for constrained whole numbers is 2^2040 (close to 16^508)

Own Id: OTP-10128

Per encoding/decoding now works correctly for single value subtyping of an integer type where a subtype is a predefined value. Previously a predefined value could cause a non-valid range-check in the generated Erlang code for per encoding/decoding due to a bug in the constraint checking.

Own Id: OTP-9688

An INTEGER with a value constraint where unions are used e.g. X1 ::= INTEGER (1..4 | 6 | 8 | 10 | 20) is not handled correctly. For PER the value is encoded in wrong number of bits.

Own Id: OTP-9946

The linked-in driver used for ber decode and per encode has been replaced with nifs. To enable the usage of nifs pass the nif option to erlc or asn1rt:compile when compiling. If you previously used the linked-in driver, you have to recompile your ASN1 modules with the current version of asn1 application as the linked-in driver modules have been removed.

*** POTENTIAL INCOMPATIBILITY ***

Own Id: OTP-9419

A few of the heavy calculations which are done for encoding and decoding operations when dealing with SEQUENCE OF and DEFAULT in runtime have been moved to be done in compile time instead.

Own Id: OTP-9440

When compiling an ASN.1 ber module with the +nif option, the module will use a new nif for ber encoding, increasing performance by about 5%.

Own Id: OTP-9441

Tuple funs (a two-element tuple with a module name and a function) are now officially deprecated and will be removed in R16. Use 'fun M:F/A' instead. To make you aware that your system uses tuple funs, the very first time a tuple fun is applied, a warning will be sent to the error logger.
