## IC 4.2.26

### Improvements and New Features

Partial support for recursive structs and unions. Only available for the erl_corba backend and requires that Light IFR is used. I.e. the IC option {light_ifr, true} and that Orber is configured in such a way that Light IFR is activated. Recursive TypeCode is currently not supported.

## IC 4.2.12

### Improvements and New Features

Dead code was deleted from the following modules: ic_cclient, ic_code, ic_cserver, ic_erlbe, ic_java_type, ic_noc, ic_plainbe, ic_pp, ic_pragma, icscan, icstruct, ictype, icunion.

## IC 4.2.11

### Improvements and New Features

Changed code generation to avoid warnings such as unused variables.

Own Id: OTP-5930 Aux Id:

## IC 4.2.10

### Fixed Bugs and Malfunctions

The FD_SETSIZE limit has been increased to 2048 for VxWorks/PPC603.

Own Id: OTP-5395 Aux Id: seq9751

## IC 4.2.9

### Fixed Bugs and Malfunctions

In C back-ends, the compiler crashed when generating C code for error reports when a scoped name was used as a type in a union.

Own Id: OTP-5375 Aux Id: seq9740

## IC 4.2.8

### Fixed Bugs and Malfunctions

In C back-ends, when decoding a sequence of "small" integers, which from Erlang is sent as a string (i.e. each element between 0 and 255), each string element was considered to be of signed character type. Each such element is now correctly treated as an unsigned character type.

Own Id: OTP-5205 Aux Id: seq9241

## IC 4.2.7

### Improvements and New Features

A new compiler option c_report has been introduced for C back-ends (client and server). If that option is set, encoding/decoding errors will be reported to stderr.

Own Id: OTP-4977

## IC 4.2.6

### Improvements and New Features

The size of modules, used then registering data in the IFR DB (e.g., oe_MyModule:oe_register()), can be minimized if the compile option light_ifr is used and Orber is configured to use Light IFR. Requires that orber-3.5.1, or later, is used.

Own Id: OTP-5036

### Incompatibilities

The compile option multiple_be is no longer supported.

Own Id: OTP-5049

## IC 4.2.5

### Improvements and New Features

Send and receive functions with timeouts have been added to the C back-ends for the standard protocol (i.e. Erlang distribution + gen_server protocol).

Accordingly a new compiler option {c_timeout, {SendTimeout, RecvTimeout}} has been added. Timeouts are specified in milliseconds.

A user that want to implement its own protocols with function timeouts has to implement the following functions.

For C clients the functions int PFX_send_notification(CORBA_Environment *env, unsigned int send_ms), and int PFX_send_request_and_receive_reply(CORBA_Environment *env, unsigned int send_ms, unsigned int recv_ms) have to be additionally implemented, where PFX is the user defined prefix.

For C servers no additional functions have to be implemented, but a clone of the int oe_server_receive_tmo(CORBA_Environment *env, oe_map_t *map, unsigned int send_ms, unsigned int recv_ms) might be handy.

Own Id: OTP-4972

## IC 4.2.4

### Improvements and new features

The C back-ends has been opened up, so that a user can define his own protocol, differing from the Erlang distribution + gen_server protocol.
For C clients it means to replace the library functions int oe_prepare_notification_encoding(CORBA_Environment *env), int oe_send_notification(CORBA_Environment *env), int oe_prepare_request_encoding(CORBA_Environment *env), int oe_send_request_and_receive_reply(CORBA_Environment *env), and int oe_prepare_reply_decoding(CORBA_Environment *env), with functions of the same signature, but with the prefix "oe" replaced by a user defined prefix. For C servers the functions int oe_prepare_request_decoding(CORBA_Environment *env), and int oe_prepare_reply_encoding(CORBA_Environment *env), are similarly replaced.
The new compiler option {user_protocol, Prefix} has been added.

Own Id: OTP-4834

## IC 4.2.3

### Fixed Bugs and Malfunctions

In generated code for the C server back-end, the naming scope was in error for prototypes in C header files for interfaces inheriting base interfaces.

Own Id: OTP-4881

## IC 4.2.2

### Fixed Bugs and Malfunctions

IDL long long and unsigned long long could not be used in a struct for the Java backend.

All unsigned integer types for the Java backend had broken marshalling for large values.

Own Id: OTP-4763

## IC 4.2.1

### Fixed Bugs and Malfunctions

A scoping problem (IC could not find typedefs contained inherited interfaces) in the C-backend solved.

Own Id: OTP-4758

## IC 4.2

### Improvements and New Features

The CORBA stub/skeleton-files generated by IC have been improved, i.e., depending on the IDL-files, reduced the size of the erl- and beam-files and decreased dependencies off Orber's Interface Repository. It is necessary to re-compile all IDL-files and use COS-applications, including Orber, compiled with IC-4.2.
