Indicate padding bytes explicitly in all the structures. Some of the
structures could have their size reduced by reordering their fields by
size (especially in owlps.h).
It is useless to handle a client structure on recvfrom() or accept()
when nothing is done with this information.
Changed in Aggregator, Listener, Positioner and UDP-to-HTTP.
Use the new terminology "capture point" (CP) instead of "access point"
(AP) everywhere in Aggregator. The only user-visible change is that the
ap_keep_timeout option is now called cp_keep_timeout.
The first field of the Aggregator's CSV output files is now an unsigned
integer that announces the version of the CSV format used. Current
version is 1 and the subsequent fields are not modified, so that an
aggregation file generated with a previous version can still be used by
adding "1;" at the beginning of each line.
The Positioner has been adapted to handle this new format.
Add the option -G (like "Generate configuration file") that dumps the
current configuration on the standard output, so the user can call
owlps-aggregatord [custom options] -G >owlps-aggregator.conf
to generate the configuration file owlps-aggregator.conf.
The file libowlps/owlps-config.h.in was added to allow CMake to pass the
installation prefix variable to the programs. That allows the programs
to look for their configuration file at the right position (i.e. in the
etc/owlps directory under the installation prefix).
We chose a centralised approach, since threads are needed in several
modules: the find_package() is done only once in the rood directory.
Not sure it's the best approach though, but this test is several lines
long so doing that avoids duplication of this code.
- 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.
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.
