Issue 6172

[garslo]

Append random string of numbers to temporary .rdmd directory (see Issue 6172).

Why not use mkstemp?

[garslo]

mkstemp hadn't occurred to me, however sticking to D seems far simpler. Also, the additional overhead of a Random() seems unimportant, especially since that portion is run only once.

[kennytm]

It's not just a problem of simplicity, but correctness. Random does not guarantee /tmp/.rdmd.[random] doesn't exist. Actually I should say mkdtemp, as mkstemp creates a file, not a directory.

And Phobos should add support for these functions in std.stdio or std.file.

And Phobos should add support for these functions in std.stdio or std.file.

Yes, definitely, I was surprised to learn that we don't have something like that (there is File.tmpfile, but it's limited and can't be used with directories).

[garslo]

Thanks for the critique, kennytm. Maybe this should wait until Phobos integrates has the indicated functions.
