For unknown reasons this seems to alleviate the word-wrap / min-height
bug on Windows. Committing so we can test and verify this is really
the case before the next release.
Move the existing aircraft history to a more obvious place, and follow
the same pattern for the complete location history. This makes restoring
a previously used configuration much simpler.
Load every file matching the pattern NavData/apt/*.dat[.gz] inside each
scenery path. These files are loaded in the same order as the components
of globals->get_unmangled_fg_scenery() they reside in. Inside a given
component, the order is determined by pathSortPredicate() in
simgear/misc/sg_dir.cxx (lexicographic order at the time of this
writing). For compatibility with existing scenery,
$FG_ROOT/Airports/apt.dat.gz is also loaded last.
The idea is that such files will have the same precedence order as the
globals->get_unmangled_fg_scenery() scenery components they come from.
This commit doesn't handle this fully yet, though: it blindly loads all
these files. A future commit will ensure that no airport is loaded twice
due to overlapping apt.dat files. This commit however handles all the
logic of navdata cache rebuilding when the list, the order of apt.dat
files, or any of their timestamps changes.
Although only apt.dat files receive a new treatment in this commit, the
changes to NavDataCache.[ch]xx are already generic so that extension of
this method to fix.dat, nav.dat, etc. will require almost no change to
NavDataCache.[ch]xx (however, changes will probably be needed in the
various loaders: in fixlist.[ch]xx, navdb.[ch]xx, etc.).
src/Navaids/CacheSchema.h:
- increment the SCHEMA_VERSION by 1. This ensures among others that if
someone uses a FlightGear version posterior to this change with
new-style scenery (having NavData/apt/*.dat[.gz] files inside
scenery paths), then goes back to a FlightGear version anterior to
this change, his NavCache is rebuilt ignoring the in-scenery-paths
NavData/apt/*.dat[.gz] files, as expected with the old FlightGear
version.
src/Navaids/NavDataCache.cxx:
- NavDataCachePrivate: replace aptDatPath (SGPath) with aptDatPaths
(PathList).
- NavDataCachePrivate::getDatFilesPaths(): new method that returns the
list of $scenery_path/NavData/<type>/*.dat[.gz] files found inside
scenery paths (where <type> is one of 'apt', 'fix', etc.), plus the
historical file (e.g., $FG_ROOT/Airports/apt.dat.gz for the 'apt'
type).
- NavDataCachePrivate::areDatFilesModified(): new method that tells
whether any of these files (for a given type) has changed since the
last NavCache rebuild, or if their ordered list has changed.
- NavDataCachePrivate::isCachedFileModified(): minor changes.
- NavDataCache::updateListsOfDatFiles(): new method that updates the
lists of dat files used for NavCache freshness checking and
rebuilding, i.e. currently sets/updates d->aptDatPaths using the new
method d->getDatFilesPaths(), and d->metarDatPath, d->navDatPath,
d->fixDatPath, d->poiDatPath, etc. as usual. This method will be
useful for instance in the built-in launcher after updating scenery
paths and before calling NavDataCache::isRebuildRequired().
- NavDataCache::NavDataCache(): use
NavDataCache::updateListsOfDatFiles() to initialize d->aptDatPaths,
d->metarDatPath, d->navDatPath, d->fixDatPath, d->poiDatPath, etc.
- NavDataCache::isRebuildRequired(): use
NavDataCachePrivate::areDatFilesModified() instead of just checking
$FG_ROOT/Airports/apt.dat.gz.
- NavDataCache::doRebuild(): load all apt.dat files listed in
d->aptDatPaths, instead of only $FG_ROOT/Airports/apt.dat.gz. Write
their ordered list and timestamps in the NavCache.
src/Navaids/NavDataCache.hxx:
- declare the new method NavDataCache::updateListsOfDatFiles().
- NavDataCache::DatFileType: new enum with values DATFILETYPE_APT,
DATFILETYPE_METAR, DATFILETYPE_AWY, DATFILETYPE_NAV,
DATFILETYPE_FIX, DATFILETYPE_POI, DATFILETYPE_CARRIER and
DATFILETYPE_TACAN_FREQ. Maybe some of the corresponding files won't
have to be moved to scenery paths, but simply listing them in the
enum doesn't change how they are dealt with. Those for which
per-scenery-path locations doesn't make sense can just be removed
from the enum.
- NavDataCache::datTypeStr: new static string_list giving an
std::string such as 'apt' for each value of the
NavDataCache::DatFileType enum.
- NavDataCache::defaultDatFile: new static string_list giving a path
(relative to $FG_ROOT) to the historical/default file for each value
of the NavDataCache::DatFileType enum.
src/Airports/apt_loader.cxx and src/Airports/apt_loader.hxx:
- always include a path to the apt.dat file being processed in log
messages, since they can now apply to many files;
- be clearer about code 99: it should normally be at the end of
apt.dat files, but technically, it is not an EOF;
- use the expression "row code" consistently with the apt.dat format
spec (for now: only in places where there is another change to do).
src/GUI/QtLauncher.cxx and src/GUI/QtLauncher_private.hxx:
- turn QtLauncher::setSceneryPaths() into a static method and call it
in runLauncherDialog() before instantiating NavDataCache, so that
NavDataCache::updateListsOfDatFiles() (called from NavDataCache's
constructor) can see all configured scenery paths.
- add a button to the main dialog, explaining how to adjust the
fg-root path via the GUI
- tweak the GUI flow to support explicitly changing the path even
when the default path is acceptable.
- change launcher to examine the scenery paths and hence load
ground-net files for airports to populate parking data.
- refactor ground-net XML parsing to use FGGroundNetwork only, not
AirportDynamics.
- change parenting of GroundNetwork to Airport, since it contains
immutable data now.
