1 asn1 Release Notes
This document describes the changes made to the asn1 application.
1.1 Asn1 1.6.2
1.1.1 Fixed Bugs and Malfunctions
-
comparison of two value definitions failed due to new
module name field in valuedef record. It is now
corrected.
Own Id: OTP-7608
1.2 Asn1 1.6.1
1.2.1 Fixed Bugs and Malfunctions
-
Bug regarding propagation of parameters of parameterized
type fixed.
Own Id: OTP-7174 Aux Id: seq10864
-
A bug, related to instatiation of a parameterized type
with a type definition in the parameterlist, has been
removed. The defininition of the parameter type was in
another module than the instance definition causing
limited module info.
Own Id: OTP-7299 Aux Id: seq10864
-
Removed hardcoded 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 behaviour occured only with decoder
generated with ber or ber_bin optionsNow 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
1.2.2 Improvements and New Features
-
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 choosen 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
occured 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
1.3 Asn1 1.6
1.3.1 Fixed Bugs and Malfunctions
-
Now is ordering, accordering 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
extensionmark, only the last of the extensionmarks 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 singlevalue constraint that
is extensible was falsely encoded/decoded in
aligned/unaligned PER. This is now corrected.
Own Id: OTP-7403
1.3.2 Improvements and New Features
-
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
1.4 Asn1 1.5.2
1.4.1 Fixed Bugs and Malfunctions
-
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.

[per_bin, optimize] options.
*** POTENTIAL INCOMPATIBILITY ***
Own Id: OTP-6882
1.7 Asn1 1.4.6
1.7.1 Fixed Bugs and Malfunctions
-
Parsing and encoding/decoding of type constrained with
SIZE with extension is now recovered.
Own Id: OTP-6763

Handling of decode pattern for exclusive decode was false
in the case when an undecoded component had more than one
following elements that should be decoded.
Own Id: OTP-6786
1.7.2 Improvements and New Features
-
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
1.8 Asn1 1.4.5
1.8.1 Fixed Bugs and Malfunctions
-
Merging modules by inline earlier disabled the
driver (used in modules generated with
[ptimized]/[optimized,driver] options). Now this is
repaired.
Own Id: OTP-6601

Support for parameterized object in an object set.
Own Id: OTP-6717
1.9 Asn1 1.4.4.14
1.9.1 Improvements and New Features
-
Data in info/0 in generated code is moved to attribute
asn1_info, thus vsn value remains the same if compiler
options for asn1-spec differs but the generated code is
the same.
Own Id: OTP-6462
-
Dialyzer warnings on asn1 are removed, i.e. dead code
removed.
Own Id: OTP-6506
1.10 Asn1 1.4.4.13
1.10.1 Improvements and New Features

options together. It is also possible to use 'inline' on
a single file like:
asn1ct:compile("MyASN1spec.asn",[inline]).
Own Id: OTP-6405
1.11 Asn1 1.4.4.12
1.11.1 Improvements and New Features
-
As a complement to the option "{inline,OutputFile}" it is
now possible to use the option "inline". Then asn1 creats
an output file with the name of the source .set file.
Own Id: OTP-6314
1.12 Asn1 1.4.4.11
1.12.1 Fixed Bugs and Malfunctions
-
When copiling an asn1 source that reference a type in
another source the compiler uses the asn1db file of the
other source to resolve the reference. It also tests
whether the other source has been updated since the
asn1db file was generated. This last test was to brutal
in that it exits compilation when no source was found,
even though a asn1db file existed. Changed behaviour from
a brutal exit to a warning.
Own Id: OTP-6143
1.13 Asn1 1.4.4.10
1.13.1 Fixed Bugs and Malfunctions
-
asn1 encoding failed on BIT STRING with constraint
(SIZE (32..MAX)).
Own Id: OTP-5932
-
Race condition removed in server for variable names for
generated code.
Own Id: OTP-6111
1.14 Asn1 1.4.4.9
1.14.1 Fixed Bugs and Malfunctions
-
Now exists a default function clause for table lookup of
a table constraint. This causes a nice error instead of a
crash. Did also remove some obsolete funs ({Mod,Fun}) in
generated code.
Own Id: OTP-5783
-
ASN1-compiler faild to derive a value out of an external
reference in some certain cases, when compiling specs so
that the spec with the reference was compiled before the
spec with the defined value.
Own Id: OTP-5812 Aux Id: seq10133
-
The documentation of how records of embedded types are
named is extended and made clearer by examples and rules.
The section "Naming of Records in .hrl Files" in the
User's Guide is added.
Own Id: OTP-5831 Aux Id: seq10133
-
The compiler failed to give right name to record/function
of a parametrized type that was referenced through
another instance of a parameterized type in another
module. The fault occured when modules were compiled in a
certain order. Now the compiler resolves the name
correctly.
Own Id: OTP-5832 Aux Id: seq10133
1.15 Asn1 1.4.4.8
1.15.1 Fixed Bugs and Malfunctions
-
The dynamic sort of SET OF values now correctly handles
values encoded in the "ber_bin, der, optimize" mode, the
value of a SET OF is a list of binaries.
Own Id: OTP-5687
-
Bad code was generated for an INTEGER with valuerange. If
the value that was encoded had a lower bound with
negative value it caused a crash. This bug is now
removed.
Own Id: OTP-5688 Aux Id: seq10049
-
Compiler now handles wrong include paths by returning an
error if a referenced module is not available.
Own Id: OTP-5689
-
The bug causing a runtime error when encoding a type
defined by: BIT STRING {a(1),b(2)} with the value
[] in per_bin mode is now removed.

-
Better handling of filename paths
Own Id: OTP-5701
1.16 Asn1 1.4.4.7

instance INTEGER (0|15..269) didn't work properly.
Own Id: OTP-5477 Aux Id: OTP-5511
-
Adjusted compiler so that functions in generated code
only are exported once.
Own Id: OTP-5509
-
Fixed the compiler failure when handling a value range
constraint with an extension mark that had the Lower
bound and/or Upper bound values as an external reference
to a defined value.
Own Id: OTP-5511 Aux Id: OTP-5466
-
Removed sorting of elements for SEQUENCE OF. It shall
only be done in SET OF.
Own Id: OTP-5602
-
Corrected code that generated code causing badarith
warning.
Own Id: OTP-5616
1.17 Asn1 1.4.4.6
1.17.1 Known Bugs and Problems
-
Compiler now correctly crashes when compiling bad values.
Failed for instance on INTEGER value that was a reference
to a defined value. Also solved problem with a union
constraint on an INTEGER.
Own Id: OTP-5457
-
Additional coverage of object set syntax.
Own Id: OTP-5466
1.18 Asn1 1.4.4.5
1.18.1 Fixed Bugs and Malfunctions
-
A bug due to representation of open_type values is now
fixed. It could cause problem if one used the EXTERNAL
type.
Own Id: OTP-5302
-
Due to an internal error the same code could have been
generated more than one time. This happened for the
exclusive deocode functionality.
Own Id: OTP-5378
1.19 Asn1 1.4.4.4
1.19.1 Fixed Bugs and Malfunctions
-
Empty objects caused problems. There was trouble when an
object set referenced imported objects that in turn
referenced imported types. Lacked support of
SelectionType in object. All these have been attended.
Own Id: OTP-5240
1.19.2 Improvements and New Features
-
Now it is possible to inline asn1 run-time functionality
in the module generated by the asn1 compiler. Thus, it
will be only one module doing all encoding/decoding.
Own Id: OTP-5243
1.20 Asn1 1.4.4.3
1.20.1 Fixed errors and malfunctions
-
A class that was referenced in two steps caused a
compiler failure. It is now corrected.
Own Id: OTP-5103
1.20.2 Improvements and new features

in missing tag in some table constraint cases. This error is
now corrected. Error occured during decode in
ber_bin optimized version.
Own Id: OTP-5022
1.22 Asn1 1.4.4.1
1.22.1 Fixed errors and malfunctions
-
When a referenced value in another module in turn referenced a
defined value the compilation crashed. This is due to the new
rutines for compilation, that external referencies are resolved
during compilation, and not by the order in which modules are
compiled. This error is now corrected.
Own Id: OTP-4970
1.23 Asn1 1.4.4
1.23.1 Fixed errors and malfunctions
-
Functionality for parameterized class is added. Parsing failures on
WithSyntax spec is corrected.

set is corrected.
Own Id: OTP-4894
Aux Id: OTP-4893
-
Object Identifier values with two components and teh first was a
value reference failed due to parsing conflicts. Now it is
corrected.
Own Id: OTP-4895
-
The errorounus comparison of file name and asn1 module name could
cause compilation failure. The situation for this failure is rare,
it requires that other processes modifies the compiled file during
the compilation procedure. It is now fixed.
Own Id: OTP-4944
Aux Id: seq8429
-
Selective decode was ignored when exclusive decode spec in asn1
configfile was missing. Selective decode failed when the selected
type was the top type. These bugs are now removed.
Own Id: OTP-4953
Aux Id: seq8436
-
The test interface asn1ct:test/1,2,3 and asn1ct:value/2 failed for
open type and EXTERNAL. The bug is now removed.
Own Id: OTP-4955
Aux Id: seq8438)

constrained with names from the names list.
Own Id: OTP-4917
-
Now there is support for SelectionType (X 680 section 29)
Own Id: OTP-4918
-
The compiler now resolves circular dependencies. When asn1 specs
IMPORTS from each other so that there are circular dependencies.
Own Id: OTP-4919
