+ - Main loop and datastructures of SURF. A cpu resource object is
+ functionnal. Surf can thus be used to create cpu's with variable
+ performance on which you can execute some actions.

+ - Port to ARM. Simply added the alignment and size descriptions. Should
+ work, but the ARM machines are so slow that I didn't had the opportunity
+ to 'make check' overthere yet.
+

+ - Trace manager now written. It uses a heap structure and is therefore
+ expected to be efficient. It may however be speeded up (particularly
+ when many events occur at the same date) by using red and black
+ trees. One day maybe...
+ - Max-min linear system solver written. It uses a sparse matrix
+ structure taking advantage of its expected use. Most operations are
+ O(1) and free/calloc are called as few as possible. The computation of
+ the minimum could however be improved by using a red and black tree
+ (again ! ;).
+

+ - Rename every gras_* function that was in xbt/ to its xbt_
+ counterpart.
+ - Add a heap and a doubly-linked list to xbt
+ - Added a dichotomy to the dictionnaries. make check works as well before
+ so I assume that the patch is correct. I do not know however if things
+ run effectively faster than before now. :)

+ - Introduction of the remote errors.
+ They are the result of a RMI/RPC on the remote machine.
+ ErrCodes being scalar values, you can't get the host on which those
+ errors did happen. Extending the error mecanism as in Gnome is possible.
+ No idea yet whether it is a good idea.
+
+2004-10-28 Martin Quinson
+ - Interface revolution: the Starred Structure Eradication.
+ I used to do typedef struct {} toto_t; and then handle *toto_t.
+ Arnaud (and Oli) didn't like it, and I surrendered. Now, you have:
+ - ???_t is a valid type (builded with typedef)
+ - s_toto_t is a structure (access to fields with .)
+ - s_toto is a structure needing 'struct' keyword to be used
+ - e_toto_t is an enum
+ - toto_t is an 'object' (struct*)
+ Exemple:
+ typedef struct s_toto {} s_toto_t, *toto_t;
+ typedef enum {} e_toto_t;
+ Moreover, only toto_t (and e_toto_t) are public. The rest (mainly
+ s_toto_t) is private.
+
+ - While I was at it, all gras_<obj>_free() functions want a gras_<obj>_t*
+ so that it can set the variable to NULL. It was so for dicts and sets,
+ it changed for dynars.
+
+ - Fix a bunch of memleaks in dict_remove
+ - Fix a bug in sg/server_socket opening: it failed all the time.
+
+2004-10-07 Martin Quinson
+ - Speed up dynar lookup operation a bit.
+
+ gras_dynar_get is dead.
+
+ Now, you can choose between gras_dynar_get_cpy (the old gras_dynar_get
+ but should be avoided for efficiency reasons) and gras_dynar_get_ptr
+ (which gives you the address of the stored data).
+
+ gras_dynar_get_as is an helpful macro which allows you to retrieve a
+ copy of the data using an affectation to do the job and not a memcpy.
+
+ int toto = gras_dynar_get_as(dyn,0,int); rewrites itself to
+ int toto = *(int*)gras_dynar_get_ptr(dyn,0);
+
+ It does not really speedup the dynar test because they are
+ setting elements all the time (and look them seldom). But the dict does
+ far more lookup than setting.
+
+ So, this brings the dict_crash test from ~33s to ~25s (200000 elms).
+
+2004-10-05 Martin Quinson
+ - Allow to (en/dis)able the cycle detection at run time.
+
+ Whether we should check for cycle or not is now a property of each
+ datatype. When you think there may be some cycle, use datadesc_cycle_set.
+ datadesc_cycle_unset allow to remove this property when previously set.
+
+ Note that the cycle detection is off by default since it impacts the
+ performance. Watch the data you feed GRAS with ;)
+
+ This property is hereditary. Any element embeeded in a structure having it
+ set have it set for the time of this data exchange.
+
+ You should set it both on sender and receiver side. If you don't set it on
+ sender side, it will enter an endless loop. If you forget on receiver
+ side, the cycles won't be recreated after communication.
+
+ - Header reorganization.
+ Kill gras_private.h, each submodule must load the headers it needs.
+
+2004-10-04 Martin Quinson
+ - Interface revolution: do not try to survive to malloc failure.
+
+ Now, gras_malloc and friends call gras_abort() on failure.
+ As a conclusion, malloc_error is not a valid error anymore, and all
+ functions for which it was the only gras_error_t return value are
+ changed. They now return void, or there result directly.
+ This simplify the API a lot.
+
+2004-09-29 Martin Quinson
+ - Re-enable raw sockets.
+ Created by gras_socket_{client,server}_ext;
+ Used with gras_raw_{send,recv}
+ No select possible.
+
+ It should allow to kill the last bits of gras first version soon.
+
+ This is not completely satisfactory yet (dupplicate code with
+ chunk_{send,recv}; a bit out of the plugin mecanism), but it should
+ work.
+
+ - Simplify transport plugin (internal) interface by not passing any
+ argument to _server and _client, but embeeding them in the socket
+ struct directly.
+
+2004-09-28 Martin Quinson
+ - Finish the port to AIX.
+ autoconf was my problem (segfault within the malloc replacement
+ function. No idea why)
