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.
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.
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.
We had some confusion between two error codes, meaning we would log an
error (and treat as a failure) a pure ocean 1x1 area, even though this
was entirely correct and expected behaviour.
Terrasync.cxx expected REPO_ERROR_NOT_FOUND, we need to convert the
file-level error to that, and avoid logging a warning.
- 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).
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.
For Windows, default file mode is TEXT.
If binary files should be created _O_BINARY shall be or'ed to the open
flags. This is not necessary on *nixes.
Introduce a SGBinaryFile as extension to SGFile which adds the flag
upon construction on Windows.
This should keep existing behaviour for all other usages of SGFile.
Avoids very long pauses blocking the terrasync thread, while existing
file trees are verified.
Also split the request queue so we don’t submit vary large numbers of
requests from a single repository, and hence block other repositories
from getting traffic.
For HTTP repositories, support some additional metrics about ongoing
transfers. Not currently exposed via properties / TerraSync API, but
will be shortly.
