Problem with log files when IE8 crashes :(

[sweetsyk00]

hi there! Firstly, thx to the author of "Grinder" cauz it's very usefull !! Need just a little fix about the log files as you can see below...

My config :

• Win XP SP3
• IE 8

The problem is when a crash occur, no log file is created or one with the first xml tag but nothing else. (fuzzer name="fuzz" browser="IE")

Stephen, did you have the same problem recently (or not) ?

Looks like a duplicate of #6 ?

oups yep u are right... did you find a solution ?

[sweetsyk00]

Hey ! So i found it ! Actually, just patched the file logger.c like below && rebuild grinder_logger.dll Enjoy ;)

VOID logMessage( wchar_t * cpMessageW ) { ...

if( !hLog && cpLogFile ) {

hLog = CreateFile( cpLogFile, GENERIC_WRITE, FILE_SHARE_READ, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, NULL );

//hLog = CreateFile( cpLogFile, GENERIC_WRITE, FILE_SHARE_READ, NULL, CREATE_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL );

...

} ... }

Thanks sweetsyk00, CreateFile is using CREATE_ALWAYS because Grinder needs to overwrite an existing log file when logging a new testcase (LOGGER_finishedTest will close and NULL out the handle), but it also needs to create the log file if it does not already exist. CREATE_ALWAYS should provide this whereas CREATE_NEW will fail if the file already exists.

I will setup an XP box and try to recreate this bug.

I just tested the latest Grinder trunk on fully patched XP SP3 with IE8 (and Ruby 1.9.3) and logging seems fine.

Does your fuzzer call logger.starting() and logger.finished() like in the example fuzzer? these two calls are important for logging to work.

I also noticed your console output doesn't show the jscript.dll being either loaded or hooked. The grinder node should print something like:

[+D+] Attached debugger to new process 1668
[+D+] Logger DLL loaded into process 1668 @ 0x10000000
[+D+] Logging process 1668 to log file 'C:\Documents and Settings\user\Local Settings\Temp\logger_1668.xml'
[+D+] jscript.dll DLL loaded into process 1668 at address 0x3D7A0000
[+D+] Resolved jscript!StrToDbl @ 0x3D7B751C
[+D+] Hooked JavaScript parseFloat() to grinder_logger.dll via proxy @ 0x02B90000

Does this step happen (perhaps you didn't cut and paste it)?

Actually, since the last fix, all is all right ! Thanks ;)

Ok, cheers. Closing this as I can't reproduce and you've now got it working! :)
