Memory Leak in RHTTPSession (S60 2nd. FP2)

[fake777]

Hi,

as previously reported here: http://discussion.forum.nokia.com/fo...t=RHttpSession and here: http://discussion.forum.nokia.com/fo...t=RHttpSession, there seems to be a memory leak in RHTTPSession of the Series60 2nd. Ed. FP2, at least in the emulator.

the test case is easy: get the HTTP Client Example v1.0: http://www.forum.nokia.com/info/sw.n..._v1_0.zip.html, compile it, run it with Epoc32\wins{cw}\c\system\Bootdata\ErrRd in place.

You will get a thread panic: Alloc <Address> 0 if you run a successfull GET and then normally exit the application.

can someone please make an official statement regarding this? a 'jep, it's broken, we know it' would ease my memory leak nightmares a lot.

thanks in advance,

Thomas Jakobi

p.s.: this should be in the c++ section. sorry. maybe someone can move this thread?

edit: added the needed 'run successfull get and exit' instruction to the test case.

Could that be related also with:

i am has the same problem with you. i develop a HTTP UP and Down Load class base on the HTTP Client Example .when it uploaded or downloaded a file and quit my application it will raise a panic. Could some one can tell me what can i do now?is there any alternate method to down up load a file?

i'm not sure, but i think i read somewhere that this is a known issue - though i didn't find it in the S60 2nd platform errata docs...

[Dexterp37]

On my side, i just want to add a field to a remote database and that's why i have to query a web page. But that is just impossible with this problem... :| And i have to get it working soon

dexterp37:
i have the same situation with you,
i must rosolve the problem soon.
dos any body knows some docs about this problem?

hi, anybody Whether already solve the problem!

help, how to solve the problem??

thk...

[Dexterp37]

Not fixed it yet :|

[fake777]

i worked around this by creating mockups of the classes using RHTTPSession that didn't use http, but returned static data, that way i could de-memory-leak my application.

still, this sucks.

[Dexterp37]

Ouch, that's pain! can you give us any example ?

Another solution is to use the beta version of the FP2 SDK. Everything works fine with this SDK but it may not be available any more..?

I can confirm however, that this is just an emulator problem. Code works fine on the device. At least for me

Hi,

Same problem is also in S60 3rd edition 1.0 SDK. I tested weblient example and when exit application after succeddfull get, application crash.

[Dexterp37]

That is driving me crazy. How is that possible that no guru has experienced this issue and knows about it?

Hi,

i'm not sure, but can you try and call "CloseSTDLIB()" (in libc/sys/reent.h) before destruction of your last class ? i'm not sure what did it, but i'm not seeing the memory leak anymore, and adding that call was the most obvious change i made...

on the other hand, i only tried it on series80, 2nd ed., where i think i saw the leak too, but it may well be this is bogus..

Thank you, i'll give it a try but.. weird
