Previously the PagedLoD range for OBJECT_STATIC etc. was purely
measured from the object reference point. For large meshes from
osm2city this was problematic, particular at DETAILED LOD ranges,
where the range of (say) 1500m would result in the mesh being
rendered at 500m distance from the edge. We fudged this by adding
1400m to the DETAILED LOD range.
Now, such meshes can specify their radius in the STG file, ensuring
they are loaded at the correct distance.
- scoped locks using lock_guard are better
- because of this the exception handler can also be removed;
although this was originally intended to manage the locks
it never did work properly with C++ exceptions.
- Remove prepending shader filenames with Compositor/.
- Always check for fallback effects in Effects/schemes.xml.
- Shadow mapping can now be disabled at night.
- New clustered shading implementation for older systems (GLSL 120 compatible).
- Miscellaneous bug fixes.
Create Uniforms for the tile_level, tile_width and tile_height.
These can be used by the fragment shader to determine the level
of detail to render and also to perform samples for borders of
landclasses.
Fixes crashes where a request times-out, but then is completed by
UDN sometime afterwards, with a free-d object. Have the DNS::Client own
requests, and be able to retrieve the udns_query to cancel them, in
the timeout case.
Fixes a couple of Sentry reports.
As of 2020-08-01, OpenBSD's system zlib is 1.2.3 which doesn't
have gzoffset(). However we can get away with this by making
gzfilebuf::approxOffset() always return zero.
Avoid a central hash cache becoming enormous, now we use the selective
download scheme for the tile dirs.
Hash name is changed to co-exist with older versions.
Use the top-level dirIndex files to determine if a 1x1 tile dir
exists, instead of proving the server via a 404. This reduces the
number of requests we make considerably, which is … important.
Add a process() method to HTTPRepository, and use this to
incrementally validate subdirs after the .dirIndex is received. This
avoids large pauses of the TerraSync thread, when all of Airports/
is validated at once.
When doing a catalog migration to a new ID (eg, 2018 -> 2020), also
mark the installed packages for installation, on the new catalog.
Related to this, when manually removing a catalog, record this fact,
so we don’t re-add it automatically due to migration.
Add unit-tests covering both of these cases.
Trying to fix a reported crash, in this code. malloc() returning null
seems unlikely but worth checking for. ALso use a unique_ptr with
a custom deleter to avoid a leak if we throw.

If TerraSync/Airports is missing, download Airport_archive.tgz instead.
In all other cases update as normal. This has the effect, that fresh
installs make many fewer requests to TerraSync servers.
Re-add (with some tweaks) the persistent tile-cache code, so that
TerraSync checks the server at most once per 24 hour period, for a
given repository path.
(Disbale the cache by setting /sim/terrasync/enable-persistent-cache=0)
