I'm calling Ns_TclAllocateInterp() from a callback in SQLite. I want to write SQLite functions using Tcl, which should be pretty easy.
The problem is that I do not know the Tcl_Interp that called 'ns_db select'. Things get complicated when current thread has no connection (otherwise I can get an interp using Ns_ConnGetInterp()).
Anyway, the problem is that Ns_TclDeAllocateInterp() does cleaning up, which also happens to delete all connection handles and local variables.
Here's an example:
test8008:nscp 1> set h [ns_db gethandle sqlite];
set s [ns_db select $h "SELECT 1"];
while {[ns_db getrow $h $s]} {}
ns_set free $stest8008:nscp 2> set h [ns_db gethandle sqlite];
set s [ns_db select $h "SELECT NOW()"];
while {[ns_db getrow $h $s]} {}
ns_set free $s
could not allocate 1 handle from pool "sqlite"So the real question is do I always have to call Ns_TclDeAllocateInterp? From the 3.4.2 sources it seems that it only does some cleaning up, so there shouldn't be any problems and there aren't any refcount checks.
