- 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)
