digitalmars.D.bugs - [Issue 11362] New: Unit test assertion failure messages not printed

           Summary: Unit test assertion failure messages not printed
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: regression
          Priority: P2
         Component: druntime
        AssignedTo: nobody puremagic.com
        ReportedBy: doob me.com



extern (C) int printf (in char*, ...);

unittest {
    printf("Reached unittest.\n");
    assert(0);
    printf("After failed assertion.\n");
}

void main () { }

The above code should print

Reached unittest
core.exception.AssertError main(7): unittest failure

And a stack trace. But after commit [1] it only prints "Reached unittest.".

I confirm this on Linux as well.

(At least the program returns non-zero status code.)

The sample program works correctly for me on Win32, Linux and OSX.

As of dmd 2.064 beta 4, that is.

Well, this is broken on git head then. The following session compares two
programs with a single assert expression.

One has it in main:

good.d:

void main()
{
    assert(false, "something is wrong");
}

The other has it in a unittest block:

unittest
{
    assert(false, "something is wrong");
}

void main()
{}

Under Linux (SL6), the former prints both the assertion failure message and the
stack trace; the latter does not do any of that. The consolation is that the
latter returns a non-zero error code.

Here is my interaction:

$ ./wbd | grep DMD
DMD64 D Compiler v2.064-devel-acc0cb0
$ cat good.d
void main()
{
    assert(false, "something is wrong");
}
$ ./wbd good.d
$ ./good
core.exception.AssertError good.d(3): something is wrong
----------------
./good() [0x401a65]
./good() [0x4019c1]
./good() [0x401ecc]
./good() [0x401c8e]
./good() [0x401e8b]
./good() [0x401c8e]
./good() [0x401c0f]
./good() [0x4019e3]
/lib64/libc.so.6(__libc_start_main+0xfd) [0x301621ecdd]
$ echo $?
1
$ cat bad.d
unittest
{
    assert(false, "something is wrong");
}

void main()
{}
$ ./wbd bad.d -unittest
$ ./bad
$ echo $?
1

Evidently. The commit identified above is not in the 2.064 beta. I'll reopen
then for 2.065.

P.S.
This issue is an example of how people like to kill "needless" safe utils and
start use of C standard library. Here we are happy it's just a coder mistake
that almost nobody of experienced developers discovered but there are also C
library bugs in our world.

IMO, we should kill the usage of C library instead and provide small fast
wrappers of OS API like the late `rt.util.console` did.
