I'm not sure where the discussion leaves us, but at the end of the day
we're in the following situation:
1. I just svn up'ed a minute ago and built dmd. It shows version 2.048.
2. This program:
unittest
{
int x = printf("inside unittest\n");
assert(x == 100000);
}
void main(string args[])
{
writeln("inside main");
}
prints this:
inside unittest
test(7): unittest failure
inside main
and exits with error code zero.
Please advise.
I just tried it (on Windows and Ubuntu) and it does not print "inside
main". Also, it needs an "import std.stdio;"
I suggest verifying that druntime/src/core/runtime.d contains the
following code:
extern (C) __gshared unittest_errors = false;
extern (C) bool runModuleUnitTests()
{
static if( __traits( compiles, backtrace ) )
{
static extern (C) void unittestSegvHandler( int signum,
siginfo_t* info, void* ptr )
{
static enum MAXFRAMES = 128;
void*[MAXFRAMES] callstack;
int numframes;
numframes = backtrace( callstack, MAXFRAMES );
backtrace_symbols_fd( callstack, numframes, 2 );
}
sigaction_t action = void;
sigaction_t oldseg = void;
sigaction_t oldbus = void;
(cast(byte*) &action)[0 .. action.sizeof] = 0;
sigfillset( &action.sa_mask ); // block other signals
action.sa_flags = SA_SIGINFO | SA_RESETHAND;
action.sa_sigaction = &unittestSegvHandler;
sigaction( SIGSEGV, &action, &oldseg );
sigaction( SIGBUS, &action, &oldbus );
scope( exit )
{
sigaction( SIGSEGV, &oldseg, null );
sigaction( SIGBUS, &oldbus, null );
}
}
if( Runtime.sm_moduleUnitTester is null )
{
foreach( m; ModuleInfo )
{
if( m )
{
auto fp = m.unitTest;
if( fp )
fp();
}
}
return !unittest_errors;
}
return Runtime.sm_moduleUnitTester();
}
and druntime/src/core/exception.d contains the following code:
extern (C) extern __gshared bool unittest_errors;
extern (C) void onUnittestErrorMsg( string file, size_t line, string msg )
{
static char[] intToString( char[] buf, uint val )
{
assert( buf.length > 9 );
auto p = buf.ptr + buf.length;
do
{
*--p = cast(char)(val % 10 + '0');
} while( val /= 10 );
return buf[p - buf.ptr .. $];
}
static struct Console
{
Console opCall( in char[] val )
{
version( Windows )
{
uint count = void;
WriteFile( GetStdHandle( 0xfffffff5 ), val.ptr,
val.length, &count, null );
}
else version( Posix )
{
write( 2, val.ptr, val.length );
}
return this;
}
Console opCall( uint val )
{
char[10] tmp = void;
return opCall( intToString( tmp, val ) );
}
}
static __gshared Console console;
unittest_errors = true;
console( file )( "(" )( line )( "): " )( msg )( "\n" );
}
If they do, then make sure you really did delete the druntime lib and
rebuild it and you're not linking with an old one.
