std.file.FileException@std/file.d(1364): /tmp/.rdmd-1000: File exists

What is the command line you are using?

Just plain simple $ rdmd test.d

gives me this error. The error disappears once I remove the directory /tmp/.rdmd-1000 manually. But reappears when I run rdmd again. I have tried running on various machines (all ubuntu 13.10 systems).

I can also confirm that the error appears with the github version
   git://github.com/D-Programming-Language/tools.git
   SHA1: 1f39ed7b6e1cbb0695d7e9b48ad559efd4193bcb
   rdmd: Use a lock file to synchronize concurrent builds in the same workDir

But does not come with rdmd compiled from one previous version

   Merge pull request #101 from andralex/rdmd

Is there a stack trace?

It's likely triggered by one of the three mkdirRecurse calls in RDMD, which calls mkdir on Posix, which is the origin of std/file.d(1364) in git-head.

Maybe there should be a check first via:

if (!path.exists())
    path.mkdirRecurse();

Andrej you are right. I tried creating a stack report, but somehow I was not able to manage that even I used a version of rdmd compiled with -g flag.

So I patched the rdmd.d as per your suggestion and it works. I have created a pull request.

My suggestion had a race condition. Looks like this pull will fix the issue: https://github.com/D-Programming-Language/phobos/pull/1818

Sorry, you're right, rdmd pull #99 depended on Phobos #1818. I moved mkdirRecurse (then called ensurePathExists) from rdmd to Phobos at Andrei's suggestion. The rdmd pull was merged, and I didn't say anything because I thought the Phobos one would be merged promptly too.
