Please give a stable solution. Thanks

Can you tell me more about how you are invoking SQLClient? I know you had some issues trying to make it a global method.

[ramsince88]

No, Now i am not trying to make it global. I am using in view did load method SQLClient* client = [SQLClient sharedInstance]; client.delegate = self; [client connect:sql_host username:db_user password:db_password database:db_name completion:^(BOOL success) { if (success) { NSString * sql = [[NSString alloc] initWithFormat:@"select * from NO_OF_PATROLS_ON_DUTY where DateField = ('%@ 00:00:00:000AM')",selected_date]; [client execute: sql completion:^(NSArray* results) { NSLog(@"%@",results); NSArray* anArray = [results objectAtIndex:0]; NSLog(@"%@",anArray); NSLog(@"No. of Businesses=%i",[anArray count]);

[client disconnect];

            }];

        }
    }];

[martinrybak]

OK thanks. Just to confirm, you are using the latest code (version 0.1.2)

[ramsince88]

Yes I update the code with changes which you told me last time.

[martinrybak]

Does it happen all the time or just sometimes? It seems like the last code fixed this for you. Any chance that you are running an old cached build?

[ramsince88]

Actually I am making a data analytic app. So fetching data from server and show in chart. User makes this process for may dates or may be for all dates of a month. So This crashing happens for some time not on every connection. I am always clean code and remove previous app for device then test. But getting same issue again.

[martinrybak]

Can you try using version 0.0.2 of the code? Tell me if you still see the issue.

https://github.com/martinrybak/SQLClient/archive/0.0.2.zip

[ramsince88]

ok.I have to import all classes or only .h and .m file?

[martinrybak]

Both

[ramsince88]

Now i test with new changes and in third trail i got crash and system indicating like this screen shot

[martinrybak]

OK so it seems to be happening in both. That's a good sanity check.

[ramsince88]

In

• (void)connectionSuccess:(void (^)(BOOL success))completion function if we comment on dbloginfree(login); then what effect happens?

[martinrybak]

Yes, that is a quick fix, but the login struct will never get deallocated so there is a memory leak. I'm working on a solution.

[ramsince88]

ok. I have tried with comment that line and test app then no crashing happen. So I think that I have to inform you. may be it help. Thanks

[martinrybak]

Like I said, it is not a permanent fix.

[ramsince88]

Ok. Please provide a permanent solution. Now I am going to sleep so please give a solution. And I will test in morning. Thanks to support me.

[martinrybak]

I just pushed a possible fix. Please download and see if you still get the crash.

[ramsince88]

Hi, Today on first time I got crash.

Saudi_Traffic_Department(1315,0xb43000) malloc: * error for object 0x1756efd0: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug

shall we use like this

• (void)disconnect { dbclose(connection); dbloginfree(login);

}

[martinrybak]

I think I found the error. Please pull the latest version and let me know, thanks.

[ramsince88]

ok. You have update code just now????

[martinrybak]

Yes, just now.

[ramsince88]

Hi, That is working perfectly. Thanks a lot

[martinrybak]

OK thank you for your contribution, please keep testing!

[martinrybak]

This fix has been tagged 0.1.3 and a new podspec has been published.

[rawaise]

Hi Martin pls can you show me how i use the latest fixed version of code as i have same problem some times

[martinrybak]

Please try the types branch. It has a lot of internal fixes, thanks.

[rawaise]

Hi Martin please i could not understand do you have mind if we can communicate in another way something like skype or fb ?
