Bug ID: 37038
           Summary: wineserver leaks memory when running my network
                    communication program
           Product: WineHQ Bugzilla
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: bugzilla-unknown

          Reporter: [e-mail]

In 1.7.22 wine, wineserver leaks memory when running my network communication
program. memory leaks 128kB at few seconds intervals. My program uses
asynchronous
 function to receive video data.

I ran wineserver -f under valgrind --leak-check=yes to get memory leaks info,
but valgrind didn't catch anything useful.

Why do you think it's a wineserver that's leaking?

After 12 hours to run the program, the wineserver's memory is around  500MB.
Wineserver will not release its memory unless killing wineserver, or closing my
program and waiting for wineserver to quit on its own.

Well, a way to find the problem is to be able to reproduce it. Can you attach
the program and instructions or a subset of the program or sample C source code
that can reproduce the issue?

What is your application doing? winsock? wininet? Is it serving data or
downloading data?

Using the SDK of the camera device, my program downloads video data from
camera(4Mb/s). It uses asynchronous function such as WSARecv() in the SDK.

Please attach a +winsock log. Run the program like:

WINEDEBUG=+winsock wine your_program.exe >> /tmp/output.txt 2>&1

Then compress and attach /tmp/output.txt. Naturally "your_program.exe" should
be your program name =)

Let it run for 2 or 3 minutes.

I see 3 TCP sockets, all connecting to the same address. It looks like only one
of them is used most of the time, the other 2 very rarely do something. You are
using overlapped structures but without callbacks so I think I should see calls
to WSAGetOverlappedResult but there are none, there is probably other way to
receive overlapped data that I'm not aware of.

This bug may be true as long as bug 36662 still exists. That bug shows some
leaks we could not find yet.

You should fix your wine:
err:wincodecs:PngEncoder_CreateInstance Trying to save PNG picture, but PNG
support is not compiled in.

I view the source code,the function ws2_async_apc() should release the memory
which is allocated in WS2_recv_base(). I add some debug info and run my
program. The debug info don't output.

Does your program also leak memory in Windows when it runs for some time?
And can you please check if adding

WaitForSingleObjectEx(GetCurrentProcess(), 0, TRUE);

at some places in your programs works around the issue?

My program doesn't leak memory in Windows when it runs for some time.

Sorry, my program uses the SDK of the camera device, I can't add
WaitForSingleObjectEx() in the SDK.

It doesn't really matter where you add it, it should be sufficient to run it
from time to time (as part of a callback for example, ...). If modifying the
program is not possible, then please attach a +server log, this should also
allow to see this issue.

WINEDEBUG=+server wine your_program.exe >> output.log 2>&1

To explain why I'm suggesting that: For bug 36662 it turned out, that the
problem was, that the program never entered alertable state after adding an APC
call to the queue. Only specific API commands enter alertable state, you can
find more information about that on the MSDN:

Thank you very much. 
In addition, my program uses WSASend() function to send data as long as bug
36662.
Do you have any idea to solve this problem?

Could you please check again with current wine git (or 1.7.38 as soon as it is
released)? I guess that this should be fixed by

Is this still an issue in wine 1.9.17 or later?

No response to request for retest in current Wine in over a year, OR hasn't
been heard from in over 3 years.

Marking abandoned. Reopen if this is still an issue and you are willing and
able to provide requested information.
