This is a clean up commit prior to the subsystem API standardisation to simplify
the diffs. It includes all SGSubsystem and SGSubsystemGroup derived classes.
- remove the old svn properties; a scan of FGAddon and FGdata showed these are not in use except for the dialog
- new property "active" - which is true when the worker thread is running.
- changes to enabled now take effect immediately; whereas before a reinit had to be issued. This could lead to confusing GUI state as the enabled property would be true but without closing the dialog (e.g. cancelling it) terrasync could be in a different state.
- use property nodes (performance optimisation)
- Rename zfstream.cxx (resp. zfstream.hxx) to gzfstream.cxx (resp.
gzfstream.hxx)
This is because these files only deal with the gzip format (RFC 1952),
while zlib can actually read and write two slightly different formats:
this one and the "ZLIB Compressed Data Format" (RFC 1950). Since I am
going to add std::streambuf and std::istream subclasses able to deal
with both formats (and supporting data sources that are general
std::istream instances, not just files), this renaming will make
things a bit clearer, I hope.
- Add new folder simgear/io/iostreams and move the following files to
this folder:
simgear/misc/gzcontainerfile.cxx
simgear/misc/gzcontainerfile.hxx
simgear/misc/gzfstream.cxx
simgear/misc/gzfstream.hxx
simgear/misc/sgstream.cxx
simgear/misc/sgstream.hxx
simgear/misc/sgstream_test.cxx
- Adapt other files accordingly (mainly #includes and CMakeLists.txt
files).
set /sim/terrasync/scenery-version=ws30 to filter the DNS NAPTR
records for service=ws30
current default (and only available) scenery version is ws20
This enables usage of multiple scenery repositories
Allows repositories to be initialised based on data in the install.
This avoids duplicate downloading of the Model and Airport data,
and the starting scenery.
Requires a corresponding FlightGear change to be functional.
Let terrasync use the http repository if
/sim/terrasync/http-server == "automatic"
resolve DNS NAPTR RR for terrasync.flightgear.org with service "ws20"
and flags "U". Pick one of the returned entries with lowest order
and preference. If more than one entry with the same order and
preference is returned, pick a random entry of those returned.
or if
/sim/terrasync/http-server != "automatic"
explicitly use the value of that property as the http server
if
/sim/terrasync/http-server is empty, fall back to the legacy
SVN repository
- since the root-level request for an HTTP repo is small, and static,
it doesn’t make sense to use the same persistent cache, especially
for initial testing.
This is some initial pieces to synchronise other pieces of base
data than scenery via the sync mechanism. An additional sync slot is
added to avoid scenery or other data blocking each other.
