converted for now).
* Fix a vicious bug in the TCP buffering mecanism which leaded to message
loss when they were small enough to fit into the buffer and sent quickly
- enough so that they can all get received in one shoot.
+ enough so that they can all get received in one shoot.
+ * gras_datadesc_by_name and gras_msgtype_by_name: now raise an exception
+ if not found. Use the *_or_null() variant for the old semantic.
+ * In gras_msg_handle, do not discard messages without callback.
+ They are probably messages to be explicitly awaited later (ie, proofs of
+ mis-synchronization in userland since they are sent before being awaited)
+ No big deal usually.
+ * gras_socket_meas_send/recv: semantic changed!
+ The numerical arguments used to be (1) the total amount of data to send
+ and (2) msg_size. This was changed to (1) msg_size and (2) amount of
+ messages. This was need for the fool willing to send more than MAXINT
+ bytes on quite fat pipes.

AMOK:
* Do really rename the hostmanagement module to peermanagement. [Mt]
Ie, rename functions from amok_hm_* to amok_pm_*. This breaks the API,
but this is rather new and this was documented in the module
documentation (poor excuses, I admit)
+ * Bandwidth measurement semantic changed! This follows the changes to
+ gras_socket_meas_send/recv explained above.
+
+ SIMDAG:
+ * A sequential mode has been added to the workstations. When a workstation
+ is in sequential mode, it can execute only one task, and the other tasks
+ are waiting in a FIFO. [Christophe Thiery]
+
+ SURF:
+ * The KCCFLN05 workstation model now handles parallel tasks. It is the
+ model for SIMDAG. [Christophe Thiery]
+ * Bug fix in the maxmin solver: Some values were close to 0 instead of
+ equal to 0, which caused some bad behaviors in
+ saturated_constraint_set_update. I now use a threshold mechanism like in
+ surf. [AL]
+
+ XBT:
+ * When running manually src/testall, you select specific units [Mt]
+ testall is the result of our cunit mecanism, and should replace all
+ the scripty thingy around since bash don't run easily on billware.
+
+ * A mallocator system has been added. [Christophe Thiery]
+ Mallocators allow you to recycle your unused objects instead of freeing them
+ and allocating new ones.
Documentation update:
* FAQ reworking + New FAQs:
- "Valgrind spits tons of errors!" [Mt]
- "How to repport bugs" [Mt]
+ - "Cross-compiling a Windows DLL of SimGrid from Linux" [Mt]
+ - Communication time measurement within MSG [AL]
+ - I experience weird communication times when I change the latency [AL]
* GRAS tutorial [Mt]
It contains:
- an introduction to the framework and to the used communication model
. Lesson 7: Using internal timers
. Lesson 8: Handling errors through exceptions
. Lesson 9: Exchanging simple data
