Subject:MySQL .net connector errors
View as plain text  



This is Sinyavin Anatoly from Intel (Moscow department). 

I attempt to use MySQL benchmark. ( Version 05 July 2005, ). 

I want to complain of MySQL .net connector. :-)


I describe symptom.

I launch MySQL benchmark with parameters


--target= --n_threads=100


and null reference exception in MySQL .net connector occurs. 

Source code investigation shows that exception rises in CharSetMap class and sometimes in 

method MySqlDataReader.GetFieldValue(). As is easy to see that benchmark provides 

multithread environment. I think that this MySQL connector is not thread safe library ...

It seems that it is very big problem as there are many multithread data base applications.


I hope that criticism helps to make MySQL software to do better.



Many thanks,

Anatoly Sinyavin
