miniSQL UDF issue

Recommended Posts

Case85

I do price comparison from web, I use Chrome browser with AutoIt and miniSQL UDF. After 1-2 hours continuously local MySQL server read/write I always got an error:
 

[ERROR] Can't initialize threads: error 1

--> ###   miniSQL v1. Debug dump   ###

--> ~ Basic information
--> Is the library active?: False
--> Do we have any errnos?: 0

--> ~ Query information
--> Input query  : 
--> Output query : 

--> Mysql error  : 

 

Please help me identify what's wrong. Looks like some buffer/memory overflow, but unfortunately I haven't enough experience to find/fix the issue.

 

Thank you.

You will need to give more info like your code and where you get the error for example

Unfortunately no more usable information.

This is a simple function as seen the error come from the miniSQL v1. Debug dump and in some case: "Is the library active?: False"
Basic questions:

- Which library?
- Why not active?
- What is changed?
- If I set a "rescue loop" (I mean, I set loop for create $MySql object)

$MySql = _miniSQL_LoadLibrary()

why not creating and returning with an error continuously (every loop produce the same error)?

How to possible monitoring or find the issue?

 

- The LAN is okay, 1Gbit/sec, no more usage.

- The function's first line of code is declare the empty variable:

Local $MySql = ""

Anyway, the script run (loop) up to 2 hours long time without any error, everything is fine, no errors, no large memory consumption, which errors can be have for use internet (site load issues, element load issues) it's already handled, the Chrome browser after each task is closed and re-opened when the next task starting.

@mLipok
Thank you for your helping hand....

Here is the UDF: 


I use as described.
My function looks like:

 

Function _GetDataFromDatabase()
    Local $MySql = ""
    $MySql = _miniSQL_LoadLibrary()
    
    ;Connect to database & Init library
    If Not $MySql.Startup("localhost", "user", "pass", "db", 3306) Then
        ConsoleWrite("Failed to start library " & $MySql.debug())
        Exit
    EndIf


- Of course I use correct connection details.
- The error message returned from here

I see my issue going to be "don't solved".
I fund as reference for my idea about "memory overflow issue", when I use larger data set to send or request from MySQL server then the load of  _miniSQL_LoadLibrary() become earlier fail like I use smallest data set between AutoIt script and MySQL server.
This is a proof for my idea about the memory overflow issue.

I'm ready to pay for your successful research and fix the issue. Please PM if interested.

Thanks.
