Hi All,
I assume, it's the right place to send this mail regarding some issues that I
have notice while using sqlite latest version 3.6.16.
I have recently moved from sqlite version 3.6.1 to 3.6.16 and while executing
the command "attach database ':memory:' as db2" I experience the crash in my
application. "db2" is an alias for my in memory database. The crash occures
inside the function attachFunc( sqlite3_context *context, int NotUsed,
sqlite3_value **argv ) in the below code snippet at condition if(
sqlite3StrICmp(z, zName)==0 ).
for(i=0; i<db->nDb; i++){
char *z = db->aDb[i].zName;
assert( z && zName );
if( sqlite3StrICmp(z, zName)==0 ){
zErrDyn = sqlite3MPrintf(db, "database %s is already in use", zName);
goto attach_error;
}
}
When i is 0, z = "main" and zName = "db2" so its ok but when i is 1, z = NULL
and zName = "db2" so sqlite3StrICmp crashes. Same situation occure while I use
version 3.6.1 code but there the crash has been avoided by applying the
condition if( z && zName && sqlite3StrICmp(z, zName)==0 ). In the new code
condition for ( z && zName ) has been removed.
I am not sure, whether I am not using the current code properly or there is a
bug in sqlite code. If, anyone can help me out of this situation, will be great.
Thanks in advance
Gaurav Sharma
