+SimGrid (3.0.2) unstable; urgency=low
+
+ XBT:
+ * New module: cunit (my jUnit implementation in ansi C) [MQ]
+ - Test units are placed directly into the library code, they get extracted
+ automatically and placed into the src/testall binary.
+ - Convert most of the XBT tests to this system.
+ * New functions: xbt_dynar_getfirst_as() and xbt_dynar_getlast_as() [MQ]
+ * XML parsing: rewrote parts of flexml to enable multiple xml parsers to
+ live in the same C code. This required to change a little bit the API
+ of surfxml parsing but shouldn't be an issue for end-users. [AL]
+ * New module: sparse graph structure with basic algorithms (this is work
+ in progress and the API is not considered to be frozen yet). [AL]
+ * Display more information on backtraces: source line & function names are
+ now displayed just like valgrind does (rely on addr2line tool) [MQ]
+ * New function: xbt_backtrace_display(). Sweet while debuging [MQ]
+ * Reworked a little bit some #include statements to load only required
+ headers. Some user code that relied on SimGrid to include stdlib or
+ stdio may need to include it by themselves. [AL]
+ * Fixed xbt/log.h. A missing SG_BEGIN_DECL prevented compilation with
+ g++. [AL]
+
+ SURF:
+ * complete rewrote of the KCCFLN05 workstation model. It is now an
+ extension of the classical CLM03 model that gracefully handles
+ failures. This is now the standard model for MSG and GRAS. It doesn't
+ handle parallel tasks yet however. [AL]
+ * Bug fix: Weights were not correctly set in the network part. This may
+ have resulted in incorrect results with simulations where there are
+ more than one flow on a given link. [AL]
+
+ MSG,GRAS:
+ * Bug fix: Processes were started in reverse order, wrt deployment file.
+ WARNING: if your code relies on this bug, please fix it. [AL]
+ * Bug fix: Add a test in MSG_task_execute to stop whenever a task is
+ being executed on two different locations. [AL]
+ * Bug fix: Failures are now better supported thanks to Derrick's tests
+ (there was many failure situations I hadn't thought of and that weren't
+ correctly handled). [AL]
+
+ GRAS:
+ * New! a real RPC mecanism, as it ought to be since too long. [MQ]
+ Exception occuring on server-side are propagated back to client (!).
+
+ API CHANGE: the callback changed their prototype. Change:
+ int my_handler(gras_socket_t expeditor, void *payload_data) {
+ to:
+ int my_handler(gras_msg_cb_ctx_t ctx , void *payload_data) {
+ gras_socket_t expeditor=gras_msg_cb_ctx_from(ctx);
+ and you're set.
+ * New! function: gras_msg_handleall to deal with all messages arriving
+ within a given period.
+
+ AMOK:
+ * Bandwidth module:
+ - Do not force experiment sizes to be expressed in kb, or it becomes
+ impossible to mesure the latency this way (needs one byte-long tests)
+ WARNING: this changes the amok_bw_* function semantic. [MQ]
+ - Implements the link saturation stuff. [MQ]
+ * Host management module:
+ New! module factorizing code that we wrote over and over [MQ].

SimGrid (3.0.1) unstable; urgency=low
XBT:
[AL]
* Bugfix: really disconnect fifo items which are remove_item()ed [AL]
* Documentation: xbt_log module unmercifully reworked [MQ]
+ * Bugfix: there was a problem with the ending of contexts with
+ the pthread backend. It caused some weird deadlock or behavior
+ depending on the pthread implementation. [AL]
+ * Bugfix: get the exceptions raised in the simulator repport where
+ and why they come from when they are not catched in time [AL, MQ]
+
+ SURF:
+ * Bugfix: Do repport the error when two non-connected hosts try to
+ exchange data (Thanks to Flavien for stumbling into this one) [AL]
+ SURF:
+ * Add additionnal checkings on communications. Assert that two
+ communicating hosts are connected by a set of links... [AL]
+
MSG:
- * Add addtionnal checkings on channel values in communication [AL]
- * New: MSG_task_get_source to see on which host a task was generated [HC]
+ * Add additionnal checkings on channel values in communication [AL]
+ * New: MSG_task_get_source to see on which host a task was generated [HC]
+ * New: int MSG_task_probe_from_host(int channel, m_host_t host): returns
+ the number of tasks waiting to be received on channel and sent
+ by host. [AL]
+ * New: MSG_error_t MSG_task_get_from_host(m_task_t * task, int channel, m_host_t host);
+ waits for the first task coming from a given host.. [AL]
+
+ GRAS new functionnalities: [MQ]
+ * Enhance the parsing macro to allow the size of multidimentional objects
+ to be given thru annotations.
+ * New example (and documentation): Matrix Multiplication a la RPC
+ (as when I was young!) and fix a bunch of bugs found on the way.
GRAS performance improvements: [MQ]
[DataDesc]
I'm not sure the potential performance gains justify the coding burden.
