移植版的 libuv:https://github.com/liigo/libuv-vc6 (支持VC6和XP,作者Liigo)。


我从一年前(大概2013年6,7月份)开始在业余时间做这项移植工作,走走停停,陆续用了一两个月的时间,才基本完成。这期间做了详细的移植记录,现在发布出来,希望对某些人有用。就在昨天(2014年7月12日),我又把移植的代码同步到最新的libuv(https://github.com/joyent/libuv)并发布到Github上;但是之前的移植记录没有变更,或许在一定程度上已经部分失效了。

我(Liigo)当初做这项移植工作的原始意图,是打算做一个封装 libuv 的易语言支持库。然而终究还没有做。理由是没有时间呢,缺乏需求呢,还是懒呢?我暂时不想下结论。

此移植版 libuv-vc6 的完整性和准确性尚未得到证明。但是我的tinyweb 已经基于该移植版编译,并且在Windows XP系统下运作正常。我想这能证明至少它是“基本可用”的。





VC6系统文件 MSWSOCK.H 编译时报错,说不认识“SOCKET”类型:
解决办法,在前面增加 typedef unsigned int  SOCKET;


uv-win.h 报错说 SRWLOCK 未定义,解决办法是在前面增加:
//http://blog.csdn.net/xiewneqi/article/details/4787156
typedef struct SRWLOCK {
void* ptr;
} SRWLOCK, *PSRWLOCK;



uv.h 未定义 sockaddr_storage,解决办法是在前面增加:
//http://stackoverflow.com/questions/1345109/why-sockaddr-storage-structure-defined-as-the-way-it-is-defined
struct sockaddr_storage {
short   ss_family;
char    __ss_pad1[6];
int64_t __ss_align;
char    __ss_pad2[112];
};


uv.h 报错说标识符 LPFN_CONNECTEX 语法错误,解决办法:
将 uv-win.h 内所有 " PASCAL (*" 替换为 " (PASCAL *" 。
把 LPFN_CONNECTEX 的定义从 uv-win.h 复制到 uv.h 报错行之前。


uv\src\winapi.h ‘_REPARSE_DATA_BUFFER‘重定义,解决办法:删除定义,或注释掉/*defined(_MSC_VER) ||*/
ULONG_PTR 未定义,加入 typedef unsigned int* ULONG_PTR;


uv\src\winapi.h 未定义LPOVERLAPPED_ENTRY?加入以下代码:
typedef struct _OVERLAPPED_ENTRY {
  ULONG_PTR    lpCompletionKey;
  LPOVERLAPPED lpOverlapped;
  ULONG_PTR    Internal;
  DWORD        dwNumberOfBytesTransferred;
} OVERLAPPED_ENTRY, *LPOVERLAPPED_ENTRY;


缺少文件iptypes.h? 在下面链接下载后放到uv\src\win
http://stuff.mit.edu/afs/athena/astaff/project/opssrc/nmap-2.54BETA34/mswin32/IPTypes.h


ERROR_INVALID_REPARSE_DATA未定义?修改为 0x00001128/*ERROR_INVALID_REPARSE_DATA*/

EAI_BADFLAGS等EAI_*未定义?加入以下代码:
/* Error codes from getaddrinfo() */
#define EAI_AGAIN           WSATRY_AGAIN
#define EAI_BADFLAGS        WSAEINVAL

#define EAI_NONAME          WSAHOST_NOT_FOUND
#define EAI_SERVICE         WSATYPE_NOT_FOUND
#define EAI_SOCKTYPE        WSAESOCKTNOSUPPORT
#define EAI_IPSECPOLICY     WSA_IPSEC_NAME_POLICY_ERROR


addrinfo/addrinfoW未定义?在uv.h前面加入以下代码:
//http://msdn.microsoft.com/en-us/library/windows/desktop/ms737530(v=vs.85).aspx
typedef struct addrinfo {
  int             ai_flags;
  int             ai_family;
  int             ai_socktype;
  int             ai_protocol;
  size_t          ai_addrlen;
  char            *ai_canonname;
  struct sockaddr  *ai_addr;
  struct addrinfo  *ai_next;
} ADDRINFOA, *PADDRINFOA;
//http://msdn.microsoft.com/en-us/library/windows/desktop/ms737529(v=vs.85).aspx
typedef struct addrinfoW {
  int              ai_flags;
  int              ai_family;
  int              ai_socktype;
  int              ai_protocol;
  size_t           ai_addrlen;
  PWSTR            ai_canonname;
  struct sockaddr  *ai_addr;
  struct addrinfoW  *ai_next;
} ADDRINFOW, *PADDRINFOW;


WT_EXECUTELONGFUNCTION未定义?替换为 0x00000010/*WT_EXECUTELONGFUNCTION*/
WT_EXECUTEONLYONCE未定义?替换为 0x00000008/*WT_EXECUTEONLYONCE*/


in6_addr未定义?在错误提示行前加入以下代码:
struct in6_addr {
  u_char  s6_addr[16];
};


FILE_FLAG_FIRST_PIPE_INSTANCE未定义?替换为 0x00080000/*FILE_FLAG_FIRST_PIPE_INSTANCE*/


JOBOBJECT_EXTENDED_LIMIT_INFORMATION未定义?在前面加入以下代码:
typedef struct _JOBOBJECT_EXTENDED_LIMIT_INFORMATION {
  JOBOBJECT_BASIC_LIMIT_INFORMATION BasicLimitInformation;
  IO_COUNTERS                       IoInfo;
  SIZE_T                            ProcessMemoryLimit;
  SIZE_T                            JobMemoryLimit;
  SIZE_T                            PeakProcessMemoryUsed;
  SIZE_T                            PeakJobMemoryUsed;
} JOBOBJECT_EXTENDED_LIMIT_INFORMATION, *PJOBOBJECT_EXTENDED_LIMIT_INFORMATION;


IO_COUNTERS未定义?在前面加入以下代码:
typedef struct _IO_COUNTERS {
  ULONGLONG ReadOperationCount;
  ULONGLONG WriteOperationCount;
  ULONGLONG OtherOperationCount;
  ULONGLONG ReadTransferCount;
  ULONGLONG WriteTransferCount;
  ULONGLONG OtherTransferCount;
} IO_COUNTERS, *PIO_COUNTERS;


JOB_OBJECT_LIMIT_BREAKAWAY_OK等未定义?在前面加入以下代码:
#define JOB_OBJECT_LIMIT_SCHEDULING_CLASS       0x80
#define JOB_OBJECT_LIMIT_PROCESS_MEMORY         0x100
#define JOB_OBJECT_LIMIT_JOB_MEMORY             0x200
#define JOB_OBJECT_LIMIT_DIE_ON_UNHANDLED_EXCEPTION 0x400
#define JOB_OBJECT_LIMIT_BREAKAWAY_OK           0x800
#define JOB_OBJECT_LIMIT_SILENT_BREAKAWAY_OK    0x1000
#define JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE      0x2000


NOINLINE未被识别?替换为 /*NOINLINE*/


((ULONG_PTR) req->event_handle | 1) 语法错误? 改为 ((DWORD) req->event_handle | 1)


IPPROTO_IPV6未定义?替换为 41/*IPPROTO_IPV6*/


IPV6_MULTICAST_HOPS未定义?替换为 10/*IPV6_MULTICAST_HOPS*/
IPV6_MULTICAST_LOOP未定义?替换为 11/*IPV6_MULTICAST_LOOP*/


WSAID_CONNECTEX未定义?替换为 {0x25a207b9,0xddf3,0x4660,{0x8e,0xe9,0x76,0xe5,0x8c,0x74,0x06,0x3e}}/*WSAID_CONNECTEX*/


JobObjectExtendedLimitInformation未定义?替换为 9/*JobObjectExtendedLimitInformation*/


UnregisterWait,UnregisterWaitEx,RegisterWaitForSingleObject等未定义?在winapi.h中加入以下代码:
typedef BOOL (WINAPI* sUnregisterWait) (HANDLE WaitHandle);
typedef BOOL (WINAPI* sUnregisterWaitEx) (HANDLE WaitHandle, HANDLE CompletionEvent);
typedef VOID (CALLBACK* WAITORTIMERCALLBACK) (PVOID lpParameter, BOOLEAN TimerOrWaitFired);
typedef BOOL (WINAPI* sRegisterWaitForSingleObject)
             (PHANDLE phNewWaitObject,
              HANDLE hObject,
              WAITORTIMERCALLBACK Callback,
              PVOID Context,
              ULONG dwMilliseconds,
              ULONG dwFlags);
然后在winapi.h/.c中参考原有代码补充必需的代码(定义函数指针变量、对其赋值等),然后把对UnregisterWait的调用改为pUnregisterWait(其他类推)。
对于其他在链接时找不到符号的Windows API函数,一并做如上处理。对于GetProcessMemoryInfo函数要做特殊处理,在两个系统DLL去找其实现函数地址:
-----------------------------------------------------
  //http://msdn.microsoft.com/en-us/library/windows/desktop/ms683219(v=vs.85).aspx
  pGetProcessMemoryInfo = (sGetProcessMemoryInfo)
    GetProcAddress(kernel32_module, "GetProcessMemoryInfo");
  if(pGetProcessMemoryInfo == NULL) {
    pGetProcessMemoryInfo = (sGetProcessMemoryInfo)
      GetProcAddress(GetModuleHandleA("Psapi.dll"), "GetProcessMemoryInfo");
  }
-----------------------------------------------------


找不到IPHlpApi.h?在这里下载:
https://docs.google.com/file/d/0B-VpknkVIm1fdnNabE1ScmlLazQ/edit?usp=sharing
为防止“重复定义IN6_ADDR”的编译错误,需要在 #include "Iphlpapi/iphlpapi.h" 之前先 #define s6_addr 。


找不到psapi.h?在这里下载:
https://docs.google.com/file/d/0B-VpknkVIm1fU3pDRTBDM3JXOWM/edit?usp=sharing


GlobalMemoryStatusEx未定义?在winapi.h加入以下代码:
typedef struct _MEMORYSTATUSEX {
  DWORD     dwLength;
  DWORD     dwMemoryLoad;
  DWORDLONG ullTotalPhys;
  DWORDLONG ullAvailPhys;
  DWORDLONG ullTotalPageFile;
  DWORDLONG ullAvailPageFile;
  DWORDLONG ullTotalVirtual;
  DWORDLONG ullAvailVirtual;
  DWORDLONG ullAvailExtendedVirtual;
} MEMORYSTATUSEX, *LPMEMORYSTATUSEX;
typedef BOOL (WINAPI* sGlobalMemoryStatusEx) (LPMEMORYSTATUSEX lpBuffer);
然后在winapi.h/.c中参考原有代码补充必需的代码(定义函数指针变量、对其赋值等),然后把对GlobalMemoryStatusEx的调用改为pGlobalMemoryStatusEx。


IP_ADAPTER_UNICAST_ADDRESS_XP未定义?替换为IP_ADAPTER_UNICAST_ADDRESS,然后
#include "Iphlpapi/iptypes.h" (来源见上文)
因为该头文件中定义的IP_ADAPTER_UNICAST_ADDRESS实质上就是IP_ADAPTER_UNICAST_ADDRESS_XP。


wmemcmp未定义?把原代码 wmemcmp(data_block->Signature, L"PERF", 4) 修改为:
memcmp(data_block->Signature, L"PERF", 4 * sizeof(TCHAR))


IF_TYPE_SOFTWARE_LOOPBACK未定义?替换为 24/*IF_TYPE_SOFTWARE_LOOPBACK*/


‘sin6_scope_id‘ : is not a member of ‘sockaddr_in6‘? 注释掉 uv-win.h 内的宏定义 UV_PLATFORM_HAS_IP6_LINK_LOCAL_ADDRESS。
或者加入下面的定义:
/* The ws2tcpip.h header included in VC6 doesn‘t define the
 * sin6_scope_id member of sockaddr_in6.  We define our own
 * version and redefine sockaddr_in6 to point to this one.
 */
struct liigo_sockaddr_in6 {
  short sin6_family;
  u_short sin6_port;
  u_long sin6_flowinfo;
  struct in6_addr sin6_addr;
  u_long sin6_scope_id;
};
#define sockaddr_in6 liigo_sockaddr_in6


调用swprintf参数过多?swprintf(path2, len + 3, fmt, pathw)改为swprintf(path2, fmt, pathw)


_set_invalid_parameter_handler是VC2005才加入到CRT函数,VC6里面没有。在libuv源代码里面直接注释掉对该函数的调用即可。


_BitScanReverse未定义?在前面加入以下代码,然后删除VC下对_BitScanReverse的调用,统一用GCC版代码即可:
//http://stackoverflow.com/questions/355967/how-to-use-msvc-intrinsics-to-get-the-equivalent-of-this-gcc-code
#ifndef __GNUC__
static unsigned int __declspec(inline) popcnt( unsigned int x )
{
    x -= ((x >> 1) & 0x55555555);
    x = (((x >> 2) & 0x33333333) + (x & 0x33333333));
    x = (((x >> 4) + x) & 0x0f0f0f0f);
    x += (x >> 8);
    x += (x >> 16);
    return x & 0x0000003f;
}
static unsigned int __declspec(inline) __builtin_clz( unsigned int x )
{
    x |= (x >> 1);
    x |= (x >> 2);
    x |= (x >> 4);
    x |= (x >> 8);
    x |= (x >> 16);
    return 32 - popcnt(x);
}
static unsigned int __declspec(inline) __builtin_ctz( unsigned int x )
{
    return popcnt((x & -x) - 1);
}
#endif
另外一个模拟实现_BitScanReverse的思路也是可行的:http://bbs.csdn.net/topics/350202744


_InterlockedOr8未定义?重新实现uv__atomic_exchange_set如下:
static char __declspec(inline) uv__atomic_exchange_set(char volatile* target) {
  //return _InterlockedOr8(target, 1);
  __asm mov ecx, target
  __asm mov al, byte ptr [ecx]
  __asm lock or byte ptr [ecx], 1
}


_aligned_malloc, _aligned_free, 等函数未定义?自己实现这两个函数,代码如下:
static void* _aligned_malloc(unsigned int size, unsigned int align) {
  unsigned int rem;
  unsigned char *op, *np;
  op = (unsigned char*) malloc(size + align);
  if(op == NULL) return NULL;
  rem = (unsigned int)op % align;
  np = op + align - rem;
  *(np-1) = (unsigned char)align - rem;
  return np;
}
static void _aligned_free(void* p) {
  if(p) {
    unsigned char n = *((unsigned char*)p - 1);
    free((unsigned char*)p - n);
  }
}


InterlockedCompareExchangePointer在新版VC中是编译器生成的函数,并不存在于kernel.dll里面,而VC6显然不可能生成该函数。解决办法:
pInterlockedCompareExchangePointer = (sInterlockedCompareExchangePointer) GetProcAddress(kernel32_module, "InterlockedCompareExchange");
//VC6 always create x86 programs. 因为VC6总是生成32位程序,不可能调用64位版的函数。


缺少常量IPPROTO_IPV6, IPV6_ADD_MEMBERSHIP, IPV6_DROP_MEMBERSHIP?在前面加入如下代码:
#ifndef IPPROTO_IPV6
#define IPPROTO_IPV6 41
#endif


#ifndef IPV6_MULTICAST_IF
#define IPV6_MULTICAST_IF 9
#endif
#ifndef IPV6_ADD_MEMBERSHIP
#define IPV6_ADD_MEMBERSHIP 12
#endif
#ifndef IPV6_DROP_MEMBERSHIP
#define IPV6_DROP_MEMBERSHIP 13
#endif


常量ERROR_INVALID_REPARSE_DATA没定义?改成下面这样:
4392/*ERROR_INVALID_REPARSE_DATA*/
