J'utilise Stackdumps avec Win32, écrire tout retour dans mon fichier journal adresses. Je correspondent à ceux-ci avec un mapfile plus tard (voir mon article [Post Mortem Debugging] [1]).
EDIT :: Problème résolu - voir ma réponse ci-dessous
.Avec Windows x64 je ne trouve pas un moyen fiable pour écrire que le retour dans le fichier journal adresses. J'ai essayé plusieurs façons:
Essai 1: pointeur Arithmétique:
CONTEXT Context;
RtlCaptureContext(&Context);
char *eNextBP = (char *)Context.Rdi;
for(ULONG Frame = 0; eNextBP ; Frame++)
{
char *pBP = eNextBP;
eNextBP = *(char **)pBP; // Next BP in Stack
fprintf(LogFile, "*** %2d called from %016LX (pBP at %016LX)\n", Frame,
(ULONG64)*(char **)(pBP + 8), (ULONG64)pBP);
}
Cela fonctionne bien dans la version de débogage - mais il se bloque dans la version. La valeur de Context.Rdi n'a pas de valeur utilisable là. J'ai vérifié les différences dans les paramètres du compilateur (Studio 2005) visuelle. Je ne l'ai pas trouvé quelque chose de suspect.
Essai 2: Utilisation StackWalk64
RtlCaptureContext(&Context);
STACKFRAME64 stk;
memset(&stk, 0, sizeof(stk));
stk.AddrPC.Offset = Context.Rip;
stk.AddrPC.Mode = AddrModeFlat;
stk.AddrStack.Offset = Context.Rsp;
stk.AddrStack.Mode = AddrModeFlat;
stk.AddrFrame.Offset = Context.Rbp;
stk.AddrFrame.Mode = AddrModeFlat;
for(ULONG Frame = 0; ; Frame++)
{
BOOL result = StackWalk64(
IMAGE_FILE_MACHINE_AMD64, // __in DWORD MachineType,
GetCurrentProcess(), // __in HANDLE hProcess,
GetCurrentThread(), // __in HANDLE hThread,
&stk, // __inout LP STACKFRAME64 StackFrame,
&Context, // __inout PVOID ContextRecord,
NULL, // __in_opt PREAD_PROCESS_MEMORY_ROUTINE64 ReadMemoryRoutine,
SymFunctionTableAccess64, // __in_opt PFUNCTION_TABLE_ACCESS_ROUTINE64 FunctionTableAccessRoutine,
SymGetModuleBase64, // __in_opt PGET_MODULE_BASE_ROUTINE64 GetModuleBaseRoutine,
NULL // __in_opt PTRANSLATE_ADDRESS_ROUTINE64 TranslateAddress
);
fprintf(gApplSetup.TraceFile, "*** %2d called from %016LX STACK %016LX FRAME %016LX\n", Frame, (ULONG64)stk.AddrPC.Offset, (ULONG64)stk.AddrStack.Offset, (ULONG64)stk.AddrFrame.Offset);
if(! result)
break;
}
Cela ne vidage non seulement les adresses de retour, mais l'ensemble de la pile. Je reçois environ 1000 lignes dans mon fichier journal en utilisant cette approche. Je peux l'utiliser, mais je dois rechercher les creux lignes et certaines données des piles se trouve être une adresse de code valide.
Essai 3: Utilisation Backtrace
static USHORT (WINAPI
*s_pfnCaptureStackBackTrace)(ULONG, ULONG, PVOID*, PULONG) = 0;
if (s_pfnCaptureStackBackTrace == 0)
{
const HMODULE hNtDll = ::GetModuleHandle("ntdll.dll");
reinterpret_cast<void*&>(s_pfnCaptureStackBackTrace)
= ::GetProcAddress(hNtDll, "RtlCaptureStackBackTrace");
}
PVOID myFrames[128];
s_pfnCaptureStackBackTrace(0, 128, myFrames, NULL);
for(int ndx = 0; ndx < 128; ndx++)
fprintf(gApplSetup.TraceFile, "*** BackTrace %3d %016LX\n", ndx, (ULONG64)myFrames[ndx]);
Les résultats en aucune information utile.
Quelqu'un at-il mis en œuvre une telle promenade de pile dans x64 qui n'écrit que les adresses de retour dans la pile? Ive vu les approches [StackTrace64] [2], [StackWalker] [3] et autres. Ils ne soit compilent et ne ils sont beaucoup trop comlicated. Il est essentiellement une tâche simple!
Sample StackDump64.cpp
#include <Windows.h>
#include <DbgHelp.h>
#include <Winbase.h>
#include <stdio.h>
void WriteStackDump()
{
FILE *myFile = fopen("StackDump64.log", "w+t");
CONTEXT Context;
memset(&Context, 0, sizeof(Context));
RtlCaptureContext(&Context);
RtlCaptureContext(&Context);
STACKFRAME64 stk;
memset(&stk, 0, sizeof(stk));
stk.AddrPC.Offset = Context.Rip;
stk.AddrPC.Mode = AddrModeFlat;
stk.AddrStack.Offset = Context.Rsp;
stk.AddrStack.Mode = AddrModeFlat;
stk.AddrFrame.Offset = Context.Rbp;
stk.AddrFrame.Mode = AddrModeFlat;
for(ULONG Frame = 0; ; Frame++)
{
BOOL result = StackWalk64(
IMAGE_FILE_MACHINE_AMD64, // __in DWORD MachineType,
GetCurrentProcess(), // __in HANDLE hProcess,
GetCurrentThread(), // __in HANDLE hThread,
&stk, // __inout LP STACKFRAME64 StackFrame,
&Context, // __inout PVOID ContextRecord,
NULL, // __in_opt PREAD_PROCESS_MEMORY_ROUTINE64 ReadMemoryRoutine,
SymFunctionTableAccess64, // __in_opt PFUNCTION_TABLE_ACCESS_ROUTINE64 FunctionTableAccessRoutine,
SymGetModuleBase64, // __in_opt PGET_MODULE_BASE_ROUTINE64 GetModuleBaseRoutine,
NULL // __in_opt PTRANSLATE_ADDRESS_ROUTINE64 TranslateAddress
);
fprintf(myFile, "*** %2d called from %016I64LX STACK %016I64LX AddrReturn %016I64LX\n", Frame, stk.AddrPC.Offset, stk.AddrStack.Offset, stk.AddrReturn.Offset);
if(! result)
break;
}
fclose(myFile);
}
void funcC()
{
WriteStackDump();
}
void funcB()
{
funcC();
}
void funcA()
{
funcB();
}
int main(int argc, char *argv[])
{
funcA();
}

La solution
J'ai finalement trouvé un moyen fiable pour connecter les cadres de pile en x64, en utilisant la fonction Windows CaptureStackBackTrace (). Comme je ne voulais pas mettre à jour mon SDK, je l'appelle via GetProcAddress (LoadLibrary ());
typedef USHORT (WINAPI *CaptureStackBackTraceType)(__in ULONG, __in ULONG, __out PVOID*, __out_opt PULONG);
CaptureStackBackTraceType func = (CaptureStackBackTraceType)(GetProcAddress(LoadLibrary("kernel32.dll"), "RtlCaptureStackBackTrace"));
if(func == NULL)
return; // WOE 29.SEP.2010
// Quote from Microsoft Documentation:
// ## Windows Server 2003 and Windows XP:
// ## The sum of the FramesToSkip and FramesToCapture parameters must be less than 63.
const int kMaxCallers = 62;
void* callers[kMaxCallers];
int count = (func)(0, kMaxCallers, callers, NULL);
for(i = 0; i < count; i++)
printf(TraceFile, "*** %d called from %016I64LX\n", i, callers[i]);
Cela fonctionne sans problème.
Autres conseils
Nous utilisons exclusivement minidumps ici. Vous pouvez générer un dépouillée qui comprend tout empilement d'informations et vider une trace de la pile d'un débogueur décent plus tard.
Il ne résout pas votre problème directement, mais je pense qu'il vous fournira un mécanisme de rapport post-mortem beaucoup mieux.
Dans l'essai 3, vous pouvez utiliser CaptureStackBackTrace () de manière incorrecte. Selon la documentation, sous Windows XP et Windows Server 2003, la somme des premier et second paramètres doit être inférieur à 63, mais dans votre cas, la somme serait 128.

Regardez, je ne sais pas si elle est pertinente:

Travailler avec le Code de l'Assemblée
Code de montage est simple au port à AMD64 et Windows 64 bits et vaut la peine pour des raisons de performance! Par exemple, vous pouvez tirer parti des nouveaux registres à usage général 64 bits (r8-r15), et nouveau en virgule flottante et 128 bits SSE / SSE2 / registres à virgule flottante (xmm8-xmm15). Cependant, il y a de nouveaux cadres de pile 64 bits et les conventions d'appel, vous devriez en apprendre davantage sur les spécifications ABI (Application binary Interface).
...
L'astuce consiste à cesser d'appeler StackWalk64 quand il retourne 0 dans stk.AddrReturn.Offset. Cela signifie qu'il n'y a plus de cadres sur la pile. Si stk.AddrReturn.Offset est non nul, vous pouvez utiliser cette valeur comme l'adresse de retour.
Si vous continuez à appeler StackWalk64 après, je suppose qu'il va essayer d'interpréter ce qui est dans les emplacements de mémoire comme une pile et renvoyer des données imprévisibles.
StackWalk64 est le bon choix, le premier appel vous donnera l'adresse de l'appelant.
Votre problème pourrait être que dans la version que vous avez beaucoup de inline en cours. L'adresse de retour ne peut pas être ce que vous attendez.
edit: il vous suffit de mettre AddrPC et AddrFrame. Assurez-vous que votre RBP et RIP sont celles correspondant à votre contexte callee.
En ce qui concerne la première question: désactiver « Omettre cadres de pile » dans la version, et le code de traçage de la pile « trivial » fonctionne
.En ce qui concerne RtlCaptureStackBackTrace, une chose que j'ai remarqué sur 32 bits de Windows est qu'il échoue si vous passez un trop grand nombre pour en FramesToCapture. Expérimentalement J'ai identifié 61 comme la valeur maximale, sans raison que je peux comprendre!
Je ne sais pas si elle est la même en 64 bits, mais cela pourrait expliquer pourquoi vous obtenez pas d'info sur.
Désassemblage RtlCaptureStackBackTrace () I a remarqué que la valeur maximale transmise à RtlCaptureStackBackTrace () doit être: framesToSkip + framesToCapture + 1 doit être inférieure à 64. sinon il retourne 0 et il n'y a pas d'autres codes d'erreur.
Lors de l'utilisation StackWalk64 vous Itère toute la pile du fil s'il existe des données valides ou non. Une fois que vous frappez une adresse de retour de 0, vous devez mettre fin à la marche, comme suit:
for (ULONG Frame = 0; ; Frame++)
{
if (FALSE == StackWalk64(...))
{
printf("Stack walk failed!\n");
break;
}
if (stackFrame.AddrPC.Offset == 0)
{
printf("Stack walk complete!\n");
break;
}
do_something();
}
