`b2 sync`: Empty regular files are created for path components, with workaround

[matt-hayden]

I don't have a log, but consider on dest the path some/path/filename.ext.

b2 sync --threads=1 --max-download-streams-per-file 1 --exclude-regex '(.*[.]tmp)' --incremental-mode $src $dest

This will create an empty regular file some/path, so on Linux some/path/filename.ext errors.

A workaround is to exclude trailing /:

b2 sync --threads=1 --max-download-streams-per-file 1 --exclude-regex '(.*[.]tmp)|(.*/$)' --incremental-mode $src $dest

Note that my /tmp is mounted noexec, so I'm running like:

TMPDIR=~/tmp b2 version
b2 command line tool, version 4.6.0 (b2sdk version 2.10.3)

@matt-hayden I was not able to reproduce your issue. Could you share a bit more details?

In the following command:

b2 sync --threads=1 --max-download-streams-per-file 1 --exclude-regex '(.*[.]tmp)' --incremental-mode $src $dest

What are the specified $src and $dest?
Does the exclude pattern filter out all the files in the destination folder?

And what is the exact error output that you're getting?
