Greetings,
I have a deadlock on my application when I use multiple threads.
I use 3 thread classes, let call them ThreadA, ThreadB, ThreadC.
ThreadA opens a sqlite connection, then creates a ThreadB which opens a
sqlite connection then creates a ThreadC which also opens a sqlite
connection (all connections to the same database). The application
creates serveral concurrent ThreadA threads.
So this looks like this:
ThreadA (open) -> ThreadB (open) -> ThreadC (open)
ThreadA (open) -> ThreadB (open) -> ThreadC (open)
ThreadA (open) -> ThreadB (open) -> ThreadC (open)
ThreadA (open) -> ThreadB (open) -> ThreadC (open)
...
The deadlock happens on eithre ThreadB or ThreadC at the time when
sqlite3_open() is called. I don't get a return code, the application
just freeze somewhere within the open method.
Now if I run DIRECT concurrent instances of ThreadB (or ThreadC) it
doesn't happen, so I'm wondering if there is an issue with threads
creating other threads that open sqlite connections.
Thanks
Voxen
