Nicholas,
Thanks again for your patience, i think were getting somewhere.
As an aside, can i just say that i dont understand why concurrency is
always such a point of confusion. I think it should be a basic
assumption that when people talk about accessing api's and data
structures in a multithr

Nicholas,
My oppologies, your right that explanation had been given.
But i didnt actually take it seriously, i guess i found it hard to
believe that it being the easier option was the only reason why this
limitation was in place.
If this is the case, then surely the fix is simple. Given that i

Hi Emerson,
I just hope you don't reinvent the wheel ;) I haven't yet had the need to
index things the way you describe it. May be I should take that as one of my
next pet projects to get a handle on this type of task.
The problem as I see it is basically, that any way you design this: If the

Michael,
Thanks for the advice. During the indexing process i need to select
and optionally insert records into a table so i cant ignore the
outcomes.
Basically the indexing process does compression, so for each document
it inserts words into a table and looks up keys. Every word in the

I respectfully disagree with the reader/writer concurrency based upon the
test_server.c model. The server thread executes each request independently and
serially. The requests may be intermingled but they are not concurrently
executed.
Maybe my definition of conccurency is different,

I think you created a column in table1 named "int" of type "id".
Try:
CREATE TABLE table2 (id int);
Then sum() should work.

I try this sql:
SELECT SUM(id) FROM table1
to sum the table rows but its return error
no such column: id

Unfortunately, since I have no way of knowing a priori what the relative
number of returned

work-around, it is
a "don't use indexes" rule.
I can't just arbitrarily assign the "plus" mark.

Emerson,
Now I understand your current implementation. You seemingly only partially
split up the work in your code. I'd schedule the database operation and not
wait on the outcome, but start on the next task. When the database finishes
and has retrieved its result, schedule some work package on a

I want to use SQLite's html output option to deliver query results as
a series of HTML rows. But I also want to insert extra HTML tags in

Michael,
Im not sure that atomic operations would be a suitable alternative.
The reason why im using events/conditions is so that the client thread
blocks until the server thread has processed the query and returned
the result. If i did not need the result then a simple queueing

Hi Emerson,
Another remark: On Windows using Events synchronization objects involves
additional kernel context switches and thus slows you down more than
necessary. I'd suggest using a queue, which makes use of the InterlockedXXX

OK Richard,
I've follow your steps and all is fine.
I've created libsqlite3.a, but how i create .so files?
Another questionwhen i compile a program using cross compile and the
libsqlite3.a lib, the executable file (in my case .cgi file) is too big!! Why?
If i strip it the size decrease a bit.
