Hi
Just for educational purposes I have been experimenting a little with the
Northwind Sqlite database contained on the sqlite official site.
Download link: http://download.vive.net/Northwind.zip.
Am I misunderstanding here or are the dates in the wrong format for sqlite
within this converted
Hello
I am still working away at this porting exercise, I have a couple of general
questions please that I would value some comments on.
The absence of a file locking mechanism in MQX means the best I can do is a
"dot lock" type locking strategy. I have implemented this now, but what is
having read the locking bits of osUnix.c numerous
times, I am still pretty much lost.

Hi
Now I have got a half ported version of Sqlite up and running on MQX I cant
put off any longer the question of file locking and how I tackle that ? For
the moment i had made the xLock() and xUnlock() the same as in osWin.c
version but with the Windows lock() and unlock() function calls

I thought I had better update this and confess to my sins. Good job no one
is reading this thread as it is an embarassingly stupid mistake :rules:
I cant believe I did this and then took so long to spot it.
int sqlite3_os_init(void)
{
static sqlite3_vfs mqxVfs = {
1,
jfpd where pMethods <> 0
This call to releaseAllSavepoints has the pMethods pointer pointing at the
sqlite3_io_methods mqxIoMethod structure, so a call to mqxClose() occurs
and a the db file is erroneously closed.
Any ideas on this would be greatly appreciated. Thanks

hello Dan
Thanks for the very speedy reply. I have just been experimenting with the
working Windows version.
I only get one hit of the winOpen() function and that is with a filename
parameter of the full path to my test.db file
So maybe it is not a temporary journal file or maybe I am

MQX is an Operating system from Freescale available for a number of their
Mid range processors. I have started the task of porting Sqlite to run on a
Coldfire V4. MQX is not as full featured as the Windows, Unix etc ports, so
it is going to be a challenge. If I ever manage to get this to
