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

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.

e346d8cf95 Reverted the timer_expired() back to the previous version (which should be correct). Removed the definition of CLOCK_LT() because it seems to only cause problems. 2009-01-24 15:20:11 +00:00

3a4a961ff5 Fixed the CLOCK_LT again. The previous revert was incorrect: the conditional was missing due to a bad copy-and-paste on my part :( 2009-01-24 10:54:44 +00:00

229d60d691 Neighbor ETX should accumulate over retransmission timeouts;
Best neighbor has minimum sum of routing metric and neighbor ETX. Previously best neighbor prioritizes routing metric before neighbor ETX, which often causes a poor neighbor with a good upstream path to be selected.
