eh? No, it does not truncate debug.log at startup.
util.cpp:
Code:
void ShrinkDebugFile()
{
// Scroll debug.log if it's getting too big
string strFile = GetDataDir() + "/debug.log";
FILE* file = fopen(strFile.c_str(), "r");
if (file && GetFilesize(file) > 10 * 1000000)
{
// Restart the file with some of the end
char pch[200000];
fseek(file, -sizeof(pch), SEEK_END);
int nBytes = fread(pch, 1, sizeof(pch), file);
fclose(file);
if (file = fopen(strFile.c_str(), "w"))
{
fwrite(pch, 1, nBytes, file);
fclose(file);
}
}
}
{
// Scroll debug.log if it's getting too big
string strFile = GetDataDir() + "/debug.log";
FILE* file = fopen(strFile.c_str(), "r");
if (file && GetFilesize(file) > 10 * 1000000)
{
// Restart the file with some of the end
char pch[200000];
fseek(file, -sizeof(pch), SEEK_END);
int nBytes = fread(pch, 1, sizeof(pch), file);
fclose(file);
if (file = fopen(strFile.c_str(), "w"))
{
fwrite(pch, 1, nBytes, file);
fclose(file);
}
}
}
init.cpp (at startup, just before writing the debug.log "header"):
Code:
if (!fDebug && !pszSetDataDir[0])
ShrinkDebugFile();
printf("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");
printf("Bitcoin version %s%s beta\n", FormatVersion(VERSION).c_str(), pszSubVer);
ShrinkDebugFile();
printf("\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n");
printf("Bitcoin version %s%s beta\n", FormatVersion(VERSION).c_str(), pszSubVer);
This feature actually annoys me, since I like to archive my debug.log. (I've disabled it on mine.)
