[Wine Bugs]

           Summary: WriteFile fails on threaded applications
           Product: Wine
           Version: 20040309
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-kernel
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: tronb at bluesquirrel.com


Tested on: Fedora Core 1 and Fedora test 1.90
Version: Latest rpm and build from source 20040309

In threaded applications, which use CreateFile, WriteFile, CloseHandle heavily 
(logging) in a threaded application, the WriteFile will fail because of a bad 
fd even when the sequence (CreateFile, WriteFile, CloseHandle) is protected as 
a critical section.


Test Code:
#include "stdafx.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#endif

int Test();
DWORD WINAPI AThread(  LPVOID lpParameter );
int Log(const char * stuff);

// The one and only application object

CWinApp theApp;

using namespace std;

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
	int nRetCode = 0;

	// initialize MFC and print and error on failure
	if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
	{
		// TODO: change error code to suit your needs
		_tprintf(_T("Fatal Error: MFC initialization failed\n"));
		nRetCode = 1;
	}
	else
	{
		Test();
	}

	return nRetCode;
}

int Test()
{
#define NUM_THREADS 10
	int ThreadNo[NUM_THREADS];
	HANDLE ThreadHandles[NUM_THREADS];
  //Start 10 threads
	for(int i=0;i<NUM_THREADS;i++)
	{
		ThreadNo[i] = i;
		ThreadHandles[i] = CreateThread(NULL, 0, AThread, &(ThreadNo
[i]), 0, NULL);
		if (ThreadHandles[i] == NULL)
			printf("CreateThread failed to create thread %d with 
GetLastError:%d\n", i, GetLastError());
	}

  printf("Created %d Threads\n", NUM_THREADS);
	DWORD result = WaitForSingleObject(ThreadHandles[0], 2L*60L*1000L);
	if (result == WAIT_TIMEOUT)
		printf("Timed out waiting for thread 0\n");

	return(i);
}



DWORD WINAPI AThread(  LPVOID lpParameter )
{
	char buffer[100];
  while(1)
	{
		int *lpint = (int*)lpParameter;
		sprintf(buffer, "This is some stuff from thread %d\n", *lpint);
		Log(buffer);
	}
}

int Log(const char * stuff)
{
  HANDLE hMutex = CreateMutex(NULL, TRUE, NULL);
	if (hMutex == 0)
	  printf("Mutex failed\n");
	
	//Wait for 5 seconds
	DWORD dwWaitResult = WaitForSingleObject( hMutex, 5000L );
	if (dwWaitResult == WAIT_TIMEOUT)
		printf("Wait timed out\n");

	if (dwWaitResult == WAIT_ABANDONED)
		printf("Wait abandoned\n");


	HANDLE hFile = CreateFile("C:\\TESTLOG.LOG", FILE_WRITE_DATA, 
FILE_SHARE_WRITE, NULL, OPEN_ALWAYS, FILE_ATTRIBUTE_NORMAL, NULL);
  if (hFile == INVALID_HANDLE_VALUE)
	{
		printf("CreateFile Failed with GetLastError of %d\n", 
GetLastError());
	}

	DWORD NewLoc = SetFilePointer (hFile, 0, NULL, FILE_END); 

	DWORD bytes_written;
	BOOL write_file_result = WriteFile(hFile, stuff, (DWORD)strlen(stuff), 
&bytes_written, NULL);
	if (write_file_result == 0)
	{
		printf("WriteFile Failed with GetLastError of %d\n", 
GetLastError());
	}

	if (CloseHandle(hFile) == 0)
    printf("CloseHandle Failed with %d\n", GetLastError());

	BOOL release_mutex_result = ReleaseMutex(hMutex);
	if (release_mutex_result == 0)
		printf("ReleaseMutex failed with %d\n", GetLastError());

	return(0);
}
