36bb3ece64 If no neighbor is found, we listen for announcements. Cleaned up debug output. 2009-02-16 01:18:53 +00:00

aaa8c9d2c9 Construct the X-MAC header on the stack instead of directly in the packet header, because the packet header may be misaligned. A bit of cleanup in the code too. 2009-02-15 22:05:06 +00:00

bed1b4cc4f Changed to use sky-checkpoint.c instead of sky-shell.c since checkpointing was disabled in sky-shell.c 2009-02-15 08:45:30 +00:00
adamdunkels
0d699abe79 Disabled checkpointing for the default sky-shell build to reduce object code size, instead added a separate sky-checkpoint build with checkpointing but without the 'sky-alldata' command 2009-02-14 22:53:00 +00:00

7781bbea58 Enabled X-MAC announcements by default, disabled polite broadcast announcements by default 2009-02-14 22:52:24 +00:00

e4b1ff461e Added MAC-layer announcement beacons to X-MAC. Configuratble through XMAC_CONF_ANNOUNCEMENTS 2009-02-14 20:35:03 +00:00

883d10e136 GC fix: isolated pages must always be allocated. 
page allocation: increased utilization because the algorithm failed to
count all space before.

style: renamed and simplified some code and names.

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.

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

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

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

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

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

98f7f9a06a sizeof on coffee_fd_set is no longer suitable since it has become a

f1fc4c879f cfs_coffee_get_fd_set() was renamed 2009-02-09 10:09:13 +00:00

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

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.

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.
