1.7  IC 4.3.1

Fixed Bugs and Malfunctions

  • Revert the structs erlang_pid, erlang_port and erlang_ref as they were before R16A (without node_org_enc) in order to be backward compatible with user code that accesses the fields of these structs.

1.8  IC 4.3

Improvements and New Features

  • Misc build updates

    Own Id: OTP-10784

  • Adapt ic for changes in erl_interface and jinterface due to utf8 atom support. This change makes ic dependent on erl_interface-3.7.10 (R16) or later in order to build.

1.9  IC 4.2.31

Fixed Bugs and Malfunctions

  • Fix bug where the ic pre-processor would ignore whitespace quoting.

    Own Id: OTP-9998

1.11  IC 4.2.29

Improvements and New Features

  • Erlang/OTP can now be built using parallel make if you limit the number of jobs, for instance using 'make -j6' or 'make -j10'. 'make -j' does not work at the moment because of some missing dependencies.

    Own Id: OTP-9451

1.12  IC 4.2.28

Fixed Bugs and Malfunctions

  • Incorrect use of ets:match changed to ets:match_object.

    Own Id: OTP-9630

    Own Id: OTP-9460

1.14  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.

    Own Id: OTP-8868 Aux Id: seq11633

    Own Id: OTP-5395 Aux Id: seq9751

1.31  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

1.32  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

1.33  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

1.34  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


  • The compile option multiple_be is no longer supported.

    Own Id: OTP-5049

1.35  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

1.36  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

1.37  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

1.38  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

1.39  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

1.40  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.
