NT 8.34 to 8.35 ... 8.38

[Alberto]

Hi, I have an app compiled with 8.34 and it works ok.
When I update to 8.35, 8.36 ... or even 8.38 I get a gpf whith the following data
If I go back to 8.34 all is ok.
I double check the dlls, etc
Any Idea?
The app only uses NT to read some web pages.
Thanks

[Bruce]

I recommend you run your program with the debug version of the clarion runtime (ie \clarion9\bin\debug\clarun.dll)

Indeed I recommend you copy the clarun.dll from \bin\debug to \bin so it's always just used.

Once you have that in, post your report again - this time it will contain line numbers etc.

cheers

With NT 8.38 and debug clarun.dll

Back to 8.34 all is ok
Thanks

Hi Alberto,

ok I forgot to mention this, but you need to be compiling your program in debug mode. If you compile your program in debug mode, and then use the debug runtime DLL, then this part of the call stack (which is the bit that is interesting) contains more useful information.

Call Stack:
0101BDB6  ClaRUN.dll:0001BDB6
004592FF
004B6A54
0044F9A9
004B7525
004277A9
00427030
010CC223  ClaRUN.dll:000CC223
010CBD0D  ClaRUN.dll:000CBD0D
77779F72

As a general tip, while developing you should aim to have debug mode turned on. It tells you lots of things that might be wrong with your code, especially if you use the debug runtime dll as a matter of habit.

cheers
Bruce

ok, thanks. I've added some code for the 8.39 build to avoid this problem.

[Alberto]

Thanks, and when will it be available?

Same with 8.39...

Hi Alberto,

an example would be the ideal so I can duplicate here.
But I'm guessing you just need to extend the test in netwww.clw on line 1360.
Perhaps do that and give us some feedback.

Or, as I say, an example would be most useful.

cheers
Bruce

[Alberto]

Bruce..
I was looking at the code in 8.34 and 8.39 and they are very different.
In 8.39 the error happens in line 1361, please see images

I run my trace proc and realized it happens the second time I read a big web page.
This is what happens first time I read it:

Fetch de: http://200.68.94.242/xoc?F=S&S=O&M=PES&Z=1
Fetch ok
Procesa lectura... 4
PortIt / Opciones 4 http://200.68.94.242/xoc?F=S&S=O&M=PES&Z=1 PageLen  : 384342
Termina Proceso lectura... 4 , segundos: 0.15

500000is the length of the PageString var in the web reading proc

When I read it again

Fetch de: http://200.68.94.242/xoc?F=S&S=O&M=PES&Z=1

As you can see there no Fetch OK and the GPF appears instead.

Ive added some lines in the Netwww.clw StoreData ROTUINE like:

StoreData           Routine
        setclipboard(clip(self._LastURLRequested)&'|'&self.PageLen &' + '& self.packet.binDataLen &' > '& self._AllocatedPageLen&'|'&|
                '['&(self.pagelen + 1)&' : '&(self.PageLen + self.packet.BinDataLen)&'] = self.packet.binData [1 : '&self.packet.binDataLen&']')

Then, when the GPS appears I get:

http://200.68.94.242/xoc?F=S&S=O&M=PES&Z=1
211208 + 1460 > 384632
[211209 : 212668] = self.packet.binData [1 : 1460]

but...212668-211209=1459 , which is OK, then What happened?!?!?

Any other code to add to debug it?


Thanks

Your debug code was exactly what I would have done - and it shows that the statement should definitely not be producing a problem.

Unless the number in self._AllocatedPageLen was incorrect for some reason. I found a recent change to the Unicode stuff which may have resulted in this value being wrong, so I've tweaked that to cope. So hopefully this is sorted in 8.40

cheers

Hi Bruce, same thing with 8.40

And here goes my setcliboard...
self.page [(208289) : (208288 + 1460)] = self.packet.binData [1 : 1460]
len(self.page)=209287

self.page len is not enought, you need at least 208288 + 1460=209748
