- Introduce the SIMIX module: factorize code between MSG and GRAS.
- Until now, GRAS were using MSG as an interface to SURF. It was
- quite difficult because both interface have several differences
- (MSG channels vs GRAS sockets were the most notable point).
- This also opens the gate to SMPI, which should occur soon.
-
- DO NOT MIX 3.2 RESULTS WITH 3.3 ONES: Simix may changes simulations
- The point is that events occuring at the exact same timestamp are
- not scheduled in the same order with the old and new version. This
- may be enough to completely change the execution of simulations.
- Sorry for the inconvenience.
+ OVERALL CHANGES:
+ * Tested successfully on AIX
+
+ GRAS:
+ * fix a bug on struct sizeof computation, which prevented the
+ exchange of arrays of structs in some conditions
+ - added a regression test about this in datadesc_usage
+ * Allow the exchange of 0-long dynamic vectors.
+ - for that, use -1 as indicator of dynamic size instead of 0
+ - This implied to change any size from unsigned long to long,
+ reducing a bit communication abilities, but I guess that with
+ 64bits being quite common, this is more than enough.
+ - This also induce a protocol change, thus bumping network protocol
+ version from 0 to 1 (if we have external users, we have to get
+ clean on that point too ;)
+ - added two regression tests about this in datadesc_usage
+ * Be more verbose when propagating local exceptions
+ This helps debugging.
+ * Display the status of simulated processes when receiving SIGINT in
+ simulation mode
+
+ MSG:
+ * Allow to control the simulation from a trace file.
+ New functions MSG_action_register() and MSG_action_trace_run()
+ The first one allows to associate a function execution to each
+ kind of action while the second one parses a trace file and
+ triggers the corresponding actions within the system.
+ For now, only a toy example is provided in examples/msg/actions
+ * Add an exemple of process migration in examples/msg/migration
+ * Fix a bug in task exchange which broke MSG_task_get_sender()
+ Add a teshsuite regression test for that.
+ [Bug: if MSG_task_get_sender() is called after sender exit,
+ bad things happen]
+ * Fix a bug which prevented suspend/resume to work properly
+
+ SIMIX:
+ * Add SIMIX_process_set_name() to change the name of the current
+ process in the log messages.
+
+ XBT:
+ * Also include strbuff from xbt.h public header
+ * xbt_ex_display(): do not free the exception after displaying
+ This allows to do more with the given exception afterward.
+ Users should call xbt_ex_free() themselves.
+ * Do not allow malloc(0) since that's not portable
+
+ Build Chain:
+ * Do not require doxygen in maintainer mode
