digitalmars.D.learn - name of map file

Just a quick question, why does the map file have a long name like so:

file_test-d-40DA973DB4C6AD075993AB5CD9866DDE.map ?

Because you're using rdmd and not using -of. rdmd comes up with an executable filename by hashing the source file's content (I'm not 100% sure why, something about filename-uniqueness or caching and change-tracking, I'd imagine). And dmd always uses the executable filename as the name of the map file (which makes sense when you consider executables made from multiple modules). If you use -of, or if you just use dmd directly, then that hash value doesn't get added.

Yeah but using -of creates an executable in the directory I provide.
RDMD is supossed to be used with hiding the executable in a temp dir,
afaik.

So it's hashing at play, ok. Just wanted to know why.

Personally I'd like RDMD to hide the map and deps files as well, I
don't know why it only hides the executable and leaves the rest of the
trash behind. (okay it's not trash, but for quick compile-test cycles
I don't need the map and dependancy files).

Hinding the exe isn't the point, having files act like scripts is. Putting the exes in some other common place allows better caching.

I also like to use RDMD as an alternate to rebuild/xfbuild (especially since xfbuild's been giving me trouble since I moved to D2).

are problems I have to re-run xfbuild several times until it finally
builds properly.

I wonder if this issue is caused by D1's shared-by-default state.

That's not the issue I'm having. xfbuild only uses one thread on my machine by default and I still had problems: http://d.puremagic.com/issues/show_bug.cgi?id=4687 Always seemed to work fine on D1/Tango though.
