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).
owl_mac_bytes_to_string() now uses a static buffer, so the caller do not
need to free the returned buffer manually. Because of this static
buffer, it is not thread-safe anymore, therefore we introduce
owl_mac_bytes_to_string_r() that is a thread-safe version.
Add some comments, add/remove some endianess conversions. That should be
OK now.
Noticeable changes in owlps.h:
- Type DIRECTION is now an alias for uint8_t instead of an enum.
- Type autocalibration_order now contains an uint8_t instead of an enum.
owl_timestamp_to_ms() did not convert properly the result to uint64_t.
This is now fixed, but time functions are still buggy, as we do not take
into account the length of tv_sec (owl_timestamp_round_to_ms() assumes
that it is 9-digit long).
The use of integer types from inttypes.h & stdint.h should help with
portability issues. It will also force the data transmission between
different architectures to work as intended (if we handle endianess
conversions correctly!).
Abandon the old struct timeval and gettimeofday(). We now use the new
struct timespec and clock_gettime().
struct timespec has a nanosecond resolution, but we lower the resolution
to keep only milliseconds. The code is inspired from the Timestamp class
of the owlps-positioning.
