To be consistent with the other modules, the positioning server must be
called OwlPS Positioner instead of Positioning, and the executable
owlps-positionerd (even if the daemon mode is not implemented yet).
That's a big commit for a tiny change.
Differentiate the port on which the autocalibration hello messages are
sent to the aggregator by the listeners, and the one on which the
autocalibration orders are sent by the aggregator to the listeners.
This will allow to run a listener and an aggregator on the same machine
with autocalibration enabled.
Both in the listener and the aggregator, the option -a (autocalibration
port) has been replaced by the options -O (autocalibration order port)
and -H (autocalibration hello port). In the listener, the option -H was
previously used to set the hello delay; this is now the role of the -T
option.
The autocalibration requests are now sent on the same port as the
positioning request, by default. There was no real reason to send them
on a different port.
Modify the *time*() functions to avoid passing structures in arguments
(using const pointers instead) or returning structures (using result
arguments instead).
"start_time" was meaningless in the global data structures of owlps.h,
and could lead to errors in the aggregator, since it defines a field
start_time in one of its internal structures.
On *BSD, usleep() does not accept an argument greater than 1'000'000 (1
second). owl_msleep() decomposes its arguments to use sleep() and
usleep() calls.
This new type of request will only be used in owlps-positioning, to
distinct the calibration requests that are issued from a real
measurement and those that are generated by the self-calibration
process.
Instead of #define DEBUG, we now prefer to use either verbose levels
or, when needed, NDEBUG. Each Makefile was modified to be able to pass
-D NDEBUG to the compiler (but the corresponding lines are commented),
except in the modules where assert is never used, in which case the
Makefile passes -D DEBUG.
Long story short: to totally disable debugging code, comment-out the
"-D DEBUG" lines and uncomment the "-D NDEBUG" lines, in every Makefile.
Use snprintf() instead of sprintf() in mac_bytes_to_string_r(). This is
really useless, but I want to satisfy the snprintf BSD zealots and get
rid of the warning GCC gives me on OpenBSD.
-lrt is now added as needed in each module Makefile, but not directly in
the library. Furthermore, the Makefiles add -lrt only if the platform is
Linux.
* libowlps, libowlps-client & owlps-listener:
Add Makefiles to compile for OpenWrt 10.03 (Backfire). (owlps-client had
one already.)
* libowlps & libowlps-client:
Update the Makefiles for OpenWrt 8.09 (Kamikaze).
