<h1>1 IDL Compiler Release Notes</h1>
<h3><a name="id61611">1.1
IC 4.2.31</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>
Fix bug where the ic pre-processor would ignore
whitespace quoting.</p>
<p>
Own Id: OTP-10109</p>
</li>
<li>
<p> A bug regarding spaces in C function prototypes has
been fixed. (Thanks to Richard O'Keefe.) </p>
<p>
Own Id: OTP-10138</p>
</li>
</ul>
<h3><a name="id61650">1.2
IC 4.2.30</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
Add generation of Erlang callback functions to generated
Erlang source code to avoid compiler warnings.</p>
<p>
Own Id: OTP-9998</p>
</li>
</ul>
<h3><a name="id61252">1.3
IC 4.2.29</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>Erlang/OTP can now be built using parallel make if you
limit the number of jobs, for instance using '<span class="code">make
-j6</span>' or '<span class="code">make -j10</span>'. '<span class="code">make -j</span>' does not
work at the moment because of some missing
dependencies.</p>
<p>
Own Id: OTP-9451</p>
</li>
</ul>
<h3><a name="id61293">1.4
IC 4.2.28</a></h3>

<p>
Own Id: OTP-9460 </p>
</li>
</ul>
<h3><a name="id62688">1.6
IC 4.2.26</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>
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.</p>
<p>
Own Id: OTP-8868 Aux Id: seq11633</p>

</li>
</ul>
<h3><a name="id62366">1.20
IC 4.2.12</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>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.</p>

<ul>
<li>
<p>Changed code generation to avoid warnings such as unused
variables.</p>
<p>Own Id: OTP-5930 Aux Id: </p>
</li>
</ul>
<h3><a name="id62430">1.22
IC 4.2.10</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>The FD_SETSIZE limit has been increased to 2048 for

<p>Own Id: OTP-5395 Aux Id: seq9751</p>
</li>
</ul>
<h3><a name="id62463">1.23
IC 4.2.9</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>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.</p>
<p>Own Id: OTP-5375 Aux Id: seq9740 </p>
</li>
</ul>
<h3><a name="id62496">1.24
IC 4.2.8</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>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.</p>
<p>Own Id: OTP-5205 Aux Id: seq9241 </p>
</li>
</ul>
<h3><a name="id62531">1.25
IC 4.2.7</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>A new compiler option <span class="code">c_report</span> has been introduced
for C back-ends (client and server). If that option is
set, encoding/decoding errors will be reported to
<span class="code">stderr</span>.</p>
<p>Own Id: OTP-4977</p>
</li>
</ul>
<h3><a name="id65232">1.26
IC 4.2.6</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>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.</p>
<p>Own Id: OTP-5036</p>
</li>
</ul>
<h4>Incompatibilities</h4>
<ul>
<li>
<p>The compile option <span class="code">multiple_be</span> is no longer supported.</p>
<p>Own Id: OTP-5049</p>
</li>
</ul>
<h3><a name="id65295">1.27
IC 4.2.5</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>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).</p>
<p>Accordingly a new compiler option <span class="code">{c_timeout, {SendTimeout, RecvTimeout}}</span> has been added. Timeouts
are specified in milliseconds.</p>
<p>A user that want to implement its own protocols with
function timeouts has to implement the following functions.</p>
<p>For C clients the functions <span class="code">int PFX_send_notification(CORBA_Environment *env, unsigned int send_ms)</span>, and <span class="code">int PFX_send_request_and_receive_reply(CORBA_Environment *env, unsigned int send_ms, unsigned int recv_ms)</span>
have to be additionally implemented, where PFX is the
user defined prefix.</p>
<p>For C servers no additional functions have to be
implemented, but a clone of the <span class="code">int oe_server_receive_tmo(CORBA_Environment *env, oe_map_t *map, unsigned int send_ms, unsigned int recv_ms)</span>
might be handy.</p>
<p>Own Id: OTP-4972</p>
</li>
</ul>
<h3><a name="id65364">1.28
IC 4.2.4</a></h3>
<h4>Improvements and new features</h4>
<ul>
<li>
<p>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. <br>
For C clients it means to replace the library functions
<span class="code">int oe_prepare_notification_encoding(CORBA_Environment *env)</span>, <span class="code">int oe_send_notification(CORBA_Environment *env)</span>, <span class="code">int oe_prepare_request_encoding(CORBA_Environment *env)</span>,
<span class="code">int oe_send_request_and_receive_reply(CORBA_Environment *env)</span>, and <span class="code">int oe_prepare_reply_decoding(CORBA_Environment *env)</span>,
with functions of the same signature, but with the prefix
"oe" replaced by a user defined prefix.
For C servers the functions <span class="code">int oe_prepare_request_decoding(CORBA_Environment *env)</span>,
and <span class="code">int oe_prepare_reply_encoding(CORBA_Environment *env)</span>, are similarly replaced. <br>
The new compiler option <span class="code">{user_protocol, Prefix}</span> has
been added.</p>
<p>Own Id: OTP-4834</p>
</li>
</ul>
<h3><a name="id65436">1.29
IC 4.2.3</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>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.</p>
<p>Own Id: OTP-4881</p>
</li>
</ul>
<h3><a name="id65470">1.30
IC 4.2.2</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>IDL long long and unsigned long long could not
be used in a struct for the Java backend.</p>
<p>All unsigned integer types for the Java backend
had broken marshalling for large values.</p>
<p>Own Id: OTP-4763</p>
</li>
</ul>
<h3><a name="id65652">1.31
IC 4.2.1</a></h3>
<h4>Fixed Bugs and Malfunctions</h4>
<ul>
<li>
<p>A scoping problem (IC could not find typedefs contained
inherited interfaces) in the C-backend solved.</p>
<p>Own Id: OTP-4758</p>
</li>
</ul>
<h3><a name="id65685">1.32
IC 4.2</a></h3>
<h4>Improvements and New Features</h4>
<ul>
<li>
<p>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.</p>
