C++/boost core engine, devices to be I2C exposed over a distributed object architecture (enter CORBA potentially), and so on, to enable distributed development potentially off-device, as well as on-device in production. I am no stranger to distributed object technology stacks, like COM-family, web services including WCF, and even a little CORBA, but it has been several years for CORBA, so need a little practical guidance, specially for targeting cross-platforms. Development would occur on a Windows-based system and target ArchLinux/ARM. What are our options? We can build the ORB to run on either platform? Can it be statically linked with the client/server? Better to dynamically link and let it run as a service? However if performance suffers and the advantages of getting out of the middle tier protocol management business aren't there, like can we talk client/server over different asynchronous TCP/IP ports, then we may end up rolling </pre> Michael Powell 2013-02-15T12:11:37 http://permalink.gmane.org/gmane.comp.corba.mico.devel/1046 <pre>Hi, I've just implemented some collections realizing some CosCollection interfaces. A collection is typed at run-time through a CosCollection::Operations object. It offers a collection some methods for element type checking and for ordering. So there's really a lot of communication between a Collection and its Operations object. After a few seconds of intensive entering, removing or looking up elements in a collection things become slower and slower and slower, … Some debugging shows that after a few seconds about 40.000 MICO::GIOPSimpleProf objects where created in the context of the Operations process. This process only runs exactly 2 Operation objects as default servants of a POA with NON-RETAIN policy. After a code review of MICO 2.3.13 (the version in use) I found that profiles where entered - using IOR::add_profile() - into a container of type IOR::IORProfileVec but will only be erased - using IOR::del_profile() - on POA creation. I think computing will become slower due to the lookup loop in IOR</pre> Thomas Schmidt 2013-01-22T01:14:03 http://permalink.gmane.org/gmane.comp.corba.mico.devel/1045 <pre>Hi, I'm currently implementing some CosCollection based classes. When testing the implementation I'll receive about 20% or more BAD_OPERATION exceptions on methods sending to my collections created for tests. When debugging I found that my collection factory will receive messages (like add_element()) directed to its formerly created collection objects. After days of debugging and code review I didn't find the reason of this failure but found a workaround: Instead of activating my collections and other objects like collection iterators or Operations objects using POA::activate_object() which implicitly generates an ObjectId, I better use POA::activate_object_with_id(). When generating my own process-wide unique ID I'll never get BAD_OPERATIONS any more. I'm developing and testing on MacOSX 10.8 in 32-bit memory mode using Xcode with LLVM gcc 4.2 compiler-suite.

Interesting comments from the GCC community members. Whilst I agree with validation of the case values against the enum, I think this really should be an error not a warning, since it results in very different behaviour when you upgrade to that version of GCC. Do you know of any plans to release a new version of MICO to include all fixes currently in the MICO HEAD.

Sun Jan 3 18:59:34 CET 2010 Karel Gardas &lt;kgardas&lt; at &gt;objectsecurity.com&gt; * fix "miscompilation" of typecode.cc by GNU C++ &gt;= 4.4 This patch fixes typecode.cc to not use TK_RECURSIVE definition since this makes GNU C++ &gt;= 4.4 miscompiling several of typecode.cc's switch statements where it simply omits case blocks where TK_RECURSIVE is used, since TK_RECURSIVE provides value which is not defined in the TCKind enum type. Whole behaviour is completed by emitted warnings: typecode.cc:&lt;line&gt;: warning: case label value is less than minimum value for type Unfortunatelly GCC community members claim the compiler is right here so I enhanced tckind.h by a provided bootstrap patch to include tk_recursive value inside the TCKind enum definition which makes GNU C++ happy and resulting MICO working again. For more information about this issue see GCC PR#42576 (http://gcc.gnu.org/bugzilla/show_bug.cg</pre> Karel Gardas 2012-10-31T17:09:19 http://permalink.gmane.org/gmane.comp.corba.mico.devel/1040 <pre>Hi I have tracked this issue down and can confirm it is another problem caused by the upgrade to gcc version 4.4. A different problem with the same cause was reported in the issue "typecode assertion failed on gcc 4.4 &lt;https://sourceforge.net/mailarchive/message.php?msg_id=29183633&gt; ". The issue is caused by a change in behaviour of the switch statement. With this version of gcc the switch statement in CORBA::TypeCode::decode (DataDecoder &amp;dc, MapPosTC *_omap, ULong level), now enters the default block instead of the "case TK_RECURSIVE:" block. This is because the value of TK_RECURSIVE is outside the range of the TCKind enum. I made the relevant changes to typecode.cc and tckind.h, and the issue is resolved.
