- Default compiler and linker flags were added silently. They are now
set in the cache if no previous values are present.
- Debug flags and regular flags have been merged.
- Position-independent code (doesn't appear in the cache because CMake
lacks variables like CMAKE_EXE_COMPILE_FLAGS):
- Shared libraries are compiled with -fPIC.
- Executables and static libraries are compiled with -fPIE.
- Executables are linked with -pie -fPIE.
libowlps-client and libowlps-resultreader were never built as shared
libraries, therefore we set their version number to 1.0.
For stable releases, the rule is to increase the minor version number
when changes are made to the library without changing the API, and to
bump the major version number (soname) in case of API change.
In the development branch and for development point releases, the soname
should not be increased, even in case of API break. The minor version
number should be bumped instead.
Following this rule, libowlps' version number is bumped to 3.1, as some
changes were made since version 3.0.
MAC addresses are more likely to vary in the right octets than in the
left octets, so we compare them starting from the end rather than from
the beginning.
The Aggregator now transmits the capture timestamp of each packet to the
positioning server. For now this timestamp is not stored, only displayed
(in verbose mode) when a request is received.
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port) has been replaced by the options -O (autocalibration order port)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.
