[rainers]

Also:

• do not download some files if already existing (for local testing of the script)
• simplify space handling

Generally LGTM 👍

[wilzbach]

Suggested change

	LIBNAME=phobos.lib
	LIBNAME=phobos32.lib

[rainers]

phobos.lib is the name of the OMF library so far. That's why I had to special case it.

Do we have more free jobs on Azure? Testing a debug build would be nice, too.

[wilzbach]

Yes we have 10x parallelism (:

[PetarKirov]

Open-source projects have unlimited free jobs and up to 10 of them can execute in parallel ;)

Thanks, good to know.

I've restored the quotes and repaired the 64-bit build (it didn't do anything after my change).

To address the failure on azure, you'll probably need to add quotes around the compiler string when building the command string in d_do_test.d line 467:

< string command = compiler;
> string command = `"` ~ compiler ~ `"`;

Yeah, noticed that, too. Added now while trying to make sure no double quoting happens.

[marler8997]

Would this smaller version work?

if (str.startsWith(`"`) || str.indexOf(' ') < 0)
    return str;
return `"` ~ str ~ `"`;

[rainers]

Not with the current default:

dmd/test/tools/d_do_test.d

Line 634 in edc9b35

envData.ccompiler = `C:\"Program Files (x86)"\"Microsoft Visual Studio 10.0"\VC\bin\amd64\cl.exe`;

Jesus BATCH is friggin weird

If you want it to also handles spaces on posix systems, you'll probably need a different implementation for posix. But not a big deal since there's probably alot of other stuff that wouldn't work with the DMD build if there were spaces in the path.

I also wouldn't expect spaces in filenames on posix to be battle tested. It's also quite a mess dealing with them between bash, make and every other tool.
