Memory Leak when using winsock.shutdown ?

[priamos]

I'm using Wine 1.0 on Puppy Linux 3.01

I wrote an application with a http-server and a socket-server for windows
and I like to use this on linux. (Delphi with Indy components)

My application works fine on windows without any memory leak.

But running with wine the VmRSS-value is permanently increased.

I use following bash-script to check this:

Code: Select all

while true; do    cat /proc/"`pidof tcpc`"/status|grep -E "VmRSS";sleep 5; done

Result:
VmRSS: 4084 kB
VmRSS: 4084 kB
VmRSS: 4084 kB
VmRSS: 4084 kB
VmRSS: 4104 kB
VmRSS: 4104 kB
VmRSS: 4108 kB
VmRSS: 4108 kB
VmRSS: 4108 kB
VmRSS: 4108 kB
VmRSS: 4108 kB
VmRSS: 4112 kB
VmRSS: 4112 kB
....
If I stop the http-requests of the client-application the VmRSS-growth of
my server-application stops too.

I found, that opening and closing of a tcp-socket is the cause of memory growth.

I detected that the api-function (used by indy components)

winsock.shutdown(FLastsocket,1);
is the cause of the memory leak.

All other functions of my application work fine.

Is there any solution ?

I'm using Wine 1.0

Upgrade, that's a really old version. Latest version is wine-1.1.18.

Sorry for the long delay.

meanwhile I upgraded my linux to wine-1.1.18.
But there is no change.

VmRSS of my application is still permanently increased.

VmRSS of my application is still permanently increased.

Then compile Wine from source and run it under valgrind with memory leak detector enabled.

Hi Vitamin

my knowledge of linux is still poor. I am not a wine developer.
This is the reason for asking of support at this place.

I can offer the source of my delphi-application for further investigations.

I will support the wine-developers in every way.

But I see no change to solve this issue for myself in a sustainable time frame.
