adamdunkels 13a3029435 Rewrote the random_rand() pseudo random number generator to use the libc rand() function instead 2009-02-11 11:09:59 +00:00
adamdunkels 585620c102 Reverted the recent change from random_rand() to rand(). It turned out that
since libc rand() returns a signed int, there were frequently problems with
timer values wrapping. By reverting to random_rand(), we can provide a
random generator that returns an unsigned and the timer problems are solved.

adamdunkels b80d3cfdb9 Added a . to the SOURCEDIRS variable so that system files can be overridden by having a file with the same name in a local directory 2009-02-11 09:03:52 +00:00
adamdunkels 9d75781a78 Added packet attributes for energy spent on a packet (RIMEBUF_ATTR_LISTEN_ENERGY and RIMEBUF_ATTR_TRANSMIT_ENERGY) 2009-02-10 23:51:12 +00:00
adamdunkels b15198b9a8 Bugfix: the Chameleon header parser modules should not clear the packet attributes, because the MAC or radio layers may have added attributes already 2009-02-10 23:49:58 +00:00
adamdunkels e1ef13dad6 Reduced the size of the packet cache from four to two to avoid falseley dismissing fresh packets (the header field that hold sequence numbers is only two bits wide, hence all sequence numbers fits in a four-entry cache...) 2009-02-10 00:44:50 +00:00
adamdunkels 6c95bd895a Added default initialization of polite announcements. Not sure where the best place for this is, but this at least allow us to start experimenting with this. 2009-02-09 22:05:33 +00:00
adamdunkels 3efb83c338 Added announcement includes 2009-02-09 21:09:42 +00:00
adamdunkels 0de445e035 Initialize the announcement module 2009-02-09 21:08:12 +00:00
adamdunkels 3670ef2f44 Rewrote the collect module so that it uses the announcement module rather than the neighbor-discovery module. This makes it possible to implement other annoumcement back-ends than the traditional broadcast-based neighbor discovery 2009-02-09 20:58:25 +00:00
adamdunkels 37e15ab537 Use C rand() instead of random_rand() 2009-02-09 20:54:49 +00:00
fros4943 51006b3f8d webserver bugfix, caused nightly wget test to fail:
* too many timer_reset will naively increase the start-time, even though timer has not expired. use timer_restart instead

nvt-se 98f7f9a06a sizeof on coffee_fd_set is no longer suitable since it has become a
pointer.

fros4943 f1fc4c879f cfs_coffee_get_fd_set() was renamed 2009-02-09 10:09:13 +00:00
fros4943 4f7f3c97b5 * added coffee_files to the protected memory needed during cfs-based checkpointing operations
* renamed cfs_coffee_get_fd_set() to cfs_coffee_get_protected_memory() to highlight that not only fd_set is protected

adamdunkels 085df6b630 Improved version of LPP with support for broadcasts as well as announcement data in the probes 2009-02-08 19:30:18 +00:00
adamdunkels 37b86b9236 Added cr/nl to end of prompt to make scripting easier 2009-02-08 19:28:57 +00:00
fros4943 2d671a1265 Nimbus look and feel is not fully supported on many linux platforms:
* changing default look and feel to cross platform l&f on linux systems

nvt-se d0a546b049 A long refactoring session yielded the following.
Technical changes:

* Factored out file specific information from the file descriptor
  structure into a new file structure.

  - Useful file metadata can be stored after the file is closed.
  - File descriptors become much smaller.
  - Significantly reduces the need to scan for the file end.

* Use correct types in all function signatures.
* Removed the directory cache.

Results:

* Enormous speed increase when opening cached files (10x-20x.)
* Multiple fd:s pointing to the same file have the correct semantics.
* About 100 bytes smaller ROM size.
* Slightly smaller static RAM size.

adamdunkels 9c4d2da561 Bugfix: it is etimer_reset() that makes timer behavior stable, not etimer_restart() 2009-02-07 22:38:01 +00:00
adamdunkels 67f649c4aa Use etimer_restart() to avoid synchronization effects from the abc_send() invocation taking time to complete 2009-02-07 22:28:25 +00:00
adamdunkels 91d280c4c9 Reverted to the old behaviour on broadcasts: send strobes for both unicast and broadcast packets. 2009-02-07 18:45:50 +00:00

adamdunkels be846d8c90 A new experimental network primitive called an 'announcement'. An
announcement is an (ID, value) tuple that is disseminated to local
area neighbors. An application or protocol can explicitly listen to
announcements from neighbors. When an announcement is heard, a
callback is invoked.

Announcements can be used for a variety of network mechanisms such as
neighbor discovery, node-level service discovery, or routing metric
dissemination.

Application programs and protocols register announcements with the
announcement module. An announcement back-end, implemented by the
system, takes care of sending out announcements over the radio, as
well as collecting announcements heard from neighbors.
