Last time I tried this (1 year or so) that was not enough, you also had to compile with an increased max path define because the IO system. I reported a bug on it at the time.

So, in my tests reentrancy seems to work, I can do various SQLite calls from inside a callback/handler. setjmp/throw out of a callback seems to work sometimes, but not always, sqlite3_exec() leaves un-finalized statements around if you do that. And it seems like that is asking for trouble in general, so I will definately disallow exceptions in callbacks in my language binding.

[sqlite] binding to parameters in PRAGMA statements doesn't work
Although it is certainly not a critical thing, it would be nice if binding a table-name parameter in a PRAGMA statement worked. executing "PRAGMA table_info (?)" produces a SYNTAX error.

[sqlite] Are callbacks re-entrant and can you setjmp/throw?
I am working on a language binding to SQLite, and I am trying to figure out what features can safely be made available to untrusted code. And I am trying to figure out if I can make callbacks/handlers/authorizer safe for untrusted code, I suspect not. So, is it safe to make normal SQLite API calls from inside a SQLite callback/handler? Is it safe to setjmp/throw out of a callback/handler? Basically is the state of the statement and database in a consistent state when callbacks/handlers are called?

[sqlite] binding to missing indexes with ?NNN parameters is odd
If I have parameters like "?3, ?" then the parameter count is 4, but I can still bind to indexes 1 and 2. Is this on purpose? Is this a good thing? Is there any way to detect that the missing indexes are missing, parameter_index and parameter_name don't provide any indication? Thanks.
