Poor stacktrace and no mad file?

Postby dors » Mon May 17, 2004 3:06 pm

I'm using madExcept with a NT Service, and the stack trace is very poor; what's also puzzling me is that I'm not seeing a .mad file -- shouldn't I find one? I do have a .map file though.

Here's an example report:

The error is triggered when calling a procedure called "TOracleSession.Logon" in a procedure of the Worker Thread called "DoDbLogin" which again is called in the Execute method of he thread, all in a unit called "main.pas". I cannot find any of that, but shouldn't I?

TIA,
Holger

The "mad" file is only there if you disable the option "append map file to binary". If you have that option enabled (which I do recommend) the map file information is stored into your exe file instead of into the external "mad" file.

Could you please update to 2.7b? That might improve the stack trace quality. You can also try the latest beta version.

http://madshi.net/madCollection.exe (2.7b)
http://madshi.net/madCollectionBeta.exe (2.7c beta 8)

The error is triggered when calling a procedure called "TOracleSession.Logon" in a procedure of the Worker Thread called "DoDbLogin" which again is called in the Execute method of he thread, all in a unit called "main.pas". I cannot find any of that, but shouldn't I?

If your description of the events is correct then you should see that, yes. However, the exception is definately raised in a thread named "hdos Worker", there's no doubt about that. That sounds a bit different to what you describe.

"hdos Worker" is the ThreadName I gave to the TWorkerThread. I have the option "append" enabled, but I think I tried also disabling this and still saw no *.mad file; will check that tomorrow.

I will also try 2.7b tomorrow and see if that improves the trace quality.

First, I found the reason why I didn't see the mad file: that extension is totally eaten by my system; the file type is something like "Link to Microsoft Access Modul", and it even has a small arrow in the icon.

Second, updating to 2.7b really helped:

Code: Select all
hread $720 (TWorkerThread):
004c1234 RMP2Service.exe Oracle        RaiseOracleError
004c445b RMP2Service.exe Oracle        TOracleSession.LogOn
0050d015 RMP2Service.exe main      332 TWorkerThread.DoDbLogin
0050d4e4 RMP2Service.exe main      464 TWorkerThread.Execute
0042ed06 RMP2Service.exe madExcept     HookedTThreadExecute
0044663c RMP2Service.exe Classes       ThreadProc
00404994 RMP2Service.exe System        ThreadWrapper
0042ec9b RMP2Service.exe madExcept     ThreadExceptFrame
>> created by thread $564 (TServiceThread) at:
0050c58a RMP2Service.exe main       94 TRMP2.ServiceStart


BTW: the reason I didn't update earlier was that I was under the impression that madExcept wasn't affected, as it wasn't mentioned in the announcement of the Yahoo! group message.

Anyway, thanks for the quick help and bearing with a noobie! :-)

Well, madDisAsm was improved in 2.7b and that indirectly helped the stack trace quality, since madExcept's stack tracing depends on a perfectly working disassembler.
