rather than being cached in the StaticRTree. This means we
can freely apply traffic data and not have stale values lying
around. It reduces the size of the RTree on disk, at the expense
of some additional data in RAM.
The need for this is that:
- On OS X if libraries are stored in custom locations (not /usr/lib or /usr/local)
and they do not embed an rpath (which is common to not have) then the developer
needs to set DYLD_LIBRARY_PATH to ensure that osrm tools can find dependent libraries
at runtime (this is normal and common).
- But as of OS X > 10.11 DYLD_LIBRARY_PATH no longer is inherited. While it works in
the main shell when running a command like `osrm-extract` you will find that when
`osrm-extract` is run by cucumber (ruby child process) then DYLD_LIBRARY_PATH
is blocked and the command cannot start.
- So, this introduces the ability to pass in a variable that the cucumber tests will
understand and can manually forward along to ensure that DYLD_LIBRARY_PATH is respected
where it counts.
The intended usage of this is therefore:
# set the environment variable
export OSRM_SHARED_LIBRARY_PATH=${DYLD_LIBRARY_PATH}
# then run cucumber tests
cucumber -p verify
- Otherwise, currently, if osrm-extract crashes at startup then
the tests continue on and will crash many many times.
- This also tests that --help returns an exit code of zero and will
catch if this behavior ever changes or is inconsistent between
the command line programs
Fixes issue #1864. Given the simple set-up:
a --> b --> c
^-----------|
This would translate into an edge based graph (ab) -> (bc),
(bc) -> (ca), (ca) -> (ab).
Starting at the end of the one-way street (ab) and going to
the beginning, the query has to find a self-loop within the
graph (ab) -> (bc) -> (ca) -> (ab), as both nodes map to the
same segment (ab).
