Core data error attempt to write a readonly database programs

And there are many great new features and improvements. Prior to query types, it was possible to write queries against database views and to execute stored procedures with EF Core, but there were limitations. You could create entities that were part of your DbContext model, create DbSets for those entities and then write queries against those DbSets.

Parsing it from apt. Parsing 20MB of text data each launch is still kind of crazy, though Collecting it from many XML files would also be slow, but there's a general point that we should be decoupling availability from loading.

Cache initialization Usually, the navdb will only be compiled once during the first start of the simulator - however, some changes may require rebuilding the cache on disk see below for details.

Touching the navdata files will cause a rebuild, so rebuilds need to take a 'reasonable' amount of time. Shipping the binary data improves first-launch perceptions, but many applications do additional work on their first launch after an install, so it's not a top concern for the time being.

This means when the search paths or order changes, we have to completely rebuild, because there's no way to restore the unmodified prior to XML overlay version.

That time will be dramatically reduced if we get the taxiway data out of apt. Usually the navdb should be under MB and normally even a rebuild should not take much longer than a few minutes. The DB schema version is tracked internally in the file, and if the schema changes during a development version 3.

The naming scheme is why the first run of a new stable release of FG always does a cache rebuild - which means you can run stable and dev versions side by side without continual cache rebuilds of course.

There are no guarantees made about the format of the file, the SQL scheme or anything. There is a version field of course, and we're not planning or expecting any changes, but we really don't want to be tied to the current scheme if we discover problems or want to add something else in the future.

This has led James to think the issue is permissions, not corruption of the DB. Of course, there could be multiple issues.

If you can find the suspect navcache, please upload it to: I also had the idea of running this subsystem in a thread. This avoids adding more strain to the main loop, making FGPythonSys even more inconspicuous. Think about searching the NavDB or appending a waypoint to a flightplan.

The funny thing is that SQLite itself is obviously based on the whole "server-less" notion. From a design standpoint, the NavDB is basically an "environmental" subsystem, i.Windows Error Codes (MSDN) - Free ebook download as PDF File .pdf), Text File .txt) or read book online for free.
