Recurrent compilations create tmp subdirectories

[MartinHjelm]

I noticed that the compilation started going slower and slower and my computer losing more and more space. It seems that for me the command

ltx2any -lf pdf main

creates subdirectories on each run instead of overwriting the current tmp directory like,

main_tmp/main_tmp/main_tmp/main_tmp...

Is this how it should be? I know that I can set the -c to delete the tmp directory on every run.

I am on a Mac with OSX 10.12.6 and ruby 2.5.1p5 and pdfTeX 3.14159265-2.6-1.40.19 (TeX Live 2018)

No, that definitely shouldn't happen. I can not reproduce it here, either.

If you speak Ruby, note how the combination of this and this should prevent the tmp folder from being copied. Not sure why this would fail (on macOS?).

• Does it only happen with -lf pdf?

• Can you reproduce the issue with the version on branch dev?

• What's the output of

  ruby -e "puts Dir.entries('.')" | grep main
  

  in that folder?
