MobileC User's Guide Updated 2010-03-29  

  • The Mobile-C User's guide has been updated to reflect changes in version 1.10.10. The new documentation has also been updated with more information regarding setting up custom build environments for building Mobile-C.

MobileC v1.10.10 Released 2010-03-16  

  • Renamed the 'ComposeAgent' family of functions to 'ComposeAgentS'. Reverted the API functions argument list to old form, without workgroup codes. This was done to preserve backward compatability with Mobile-C versions 1.10.8 and prior.

MobileC v1.10.9 Released 2010-01-07  

  • Improved performance of the Mobile-C Networking code. Agent migrations now occur at an improved rate.
  • Improved performance of running a large number of agents at a time.
  • Added conceptual agent "workgroups" where each agent may store a secret "workgroup code". Only agents that share a certain workgroup code may perform certain operations on each other, such as agent deletion and data retrieval. This prevents random, malicious agents from interacting with workgroup-enabled agents in a bad way.
  • Mobile-C now pre-initialized a number of interpreters for increased performance. Number of preloaded interpreters may be adjusted in the Mobile-C Options structure passed into MC_Initialize().
  • Numerous bugfixes.

MobileC v1.10.8 Released 2009-4-29  

  • Added new Security Module written by Najmus Malik. Use the "--enable-security=yes" option during the configure step to enable the security module. See the demos in demos/hello_world_secure and demos/multi_task_example_secure , as well as Chapter 9 in the User's guide.
  • Added MC_MigrateAgent() and mc_MigrateAgent(). These functions allow an agent to dynamically choose where and when it wants to migrate from within the agent code space.
  • Fixed bug where if an agent has multiple tasks on the same host (in succession), the agent will be renamed due to a spurious name collision.

MobileC v1.10.7 Released 2009-1-9  

  • Changed the way agent migration message files are parsed and sent. Before, the files were not parsed at all before being sent. Now, agent xml files are fully parsed before being sent. This means that the syntax checking for the agent xml files will be more strict. Some agent xml files in the demos have been updated to reflect this.
  • Added more documentation regarding persistent agents and the Ch Mobile-C Package, which is required for agent FIPA ACL communication.

MobileC v1.10.6 Released 2008-12-12  

  • Changed the way agent migration message files are sent. The XML files are now fully parsed into agents before being sent.
  • Fixed a number of memory leaks.

MobileC v1.10.5 Released 2008-11-12  

  • Fixed MC_RetrieveAgent() : The function no longer returns a shallow copy of the retrieved agent, but a pointer to the actual agent.
  • Added a new demo example at "demos/multi_data_retrieval"

MobileC v1.10.4 Released 2008-10-24  

  • Added function MC_CallAgentFunc which takes a variable number of arguments.

MobileC v1.10.3 Released 2008-07-31  

  • Added documentation about Mobile-C and 64 bit architecture machines.
  • Added example for MC_ComposeAgent API function at demos/mc_compose_agent_example/

MobileC v1.10.2 Released 2008-07-11  

  • Fixed a bug regarding large agents and http/tcp protocol causing EOF errors, particularly on Gumstix systems.
  • Added FIPA enumerations to libmc.h so that they may be accessed by including only libmc.h.
  • Updated documentation to reflect previous change.
  • Upgraded included xyssl package from version 0.7 to 0.9. This fixes a Mac compile-time error regarding xyssl.

MobileC v1.10.1 Released 2008-07-01

  • Updated Windows version. Rudimentary testing of all demos in Windows is a success.
  • Ran everything through a memory leak checker again. Some memory leaks and errors fixed.
  • Created two seperate Windows project directories for VCNET 2003 and VCNET 2005.
  • Added new agent feature: Agents may now contain seperate blocks of code a la version 1.0. See agents in 'demos/multi_task_example' for an example.

MobileC v1.9.0 Released 2007-08-30

    • Files are more clearly named and organized.
    • Rewrote XML parser
    • Reorganized agent XML format
    • Extensive use of C macros for declaring/defining multiple queue objects. This is good and bad: Makes the code a little weirder to read, but saves a lot of debugging trouble, as only the macros need to be modified if there is any bug with the queues.
  • Added simple symmetric encryption option for added security.
  • Added MobileC Barriers: Execution based on MPI Barriers. See demos/agent_squad_test

  • The standalone build option is now deprecated. The functionality the standalone Mobile-C program is now entirely emulated by the mc_sample_app application, located in demos/libmc/mc_sample_app/. By enabling the command prompt thread (CP_THREAD), mc_sample_app execution becomes identical to the old standalone MobileC app.
  • Agents may now specify their own initial execution status with the 'status' attribute in the node.
  • All configure scripts now use GNU Autotools and libtool.
  • Removed standalone compile option. 'demos/libmc/mc_sample_app' offers identical functionality using the MobileC library, libmc.
  • Changed naming conventions of MobileC API functions: i.e. mc_handle_init() is now MC_HandleInit() .
  • Added CDATA section in XML Agent files to hold source code.
  • Added agent persistence
