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.

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.
