[fdo-internals] RE: SDF feature reader

[Badreddine Karoui]

The SDF provider is per connection threaded which means only one thread can access a reader at a time. You can have many threads using their own connections/readers at the same time.

Subject: [fdo-internals] SDF feature reader

Hi,
I have issue when when more than one feature reader is created against same SDF connection
It looks like same buffer ( created by sqlite cursor ) is shared betwean feature readers.
This will cause that data returned from feature reader with function GetGeometry will be corrupted when another reader is used.
Is this a bug or I am not looking into it correctly ?

I would like to be able to use multi thread access to sqlite database.
If I am right, SDF provider is not "thread safe" ? if so, what are main reasons for  it ?

Thank you,
Haris
