DONOTMERGE: Investigating archlinux failure on circlecli

[dridi]

Not expecting much from the initial debugging attempt.

For some reason all directories created under _build/sub/ during distcheck have friendly permissions except the offending one:

$ awk '/^d/ {print $1}' /tmp/_build.txt | sort | uniq -c
     90 drwxr-xr-x
      1 dr-x------
$ awk '/^dr-/' /tmp/_build.txt
dr-x------  2 varnish varnish    4096 Feb  6 08:27 varnish-trunk/_build/sub/varnish-trunk/doc/sphinx/dev-guide

Why this directory and not another?

$ awk '/^d/ && $NF ~ "sphinx/" {print $1 " " $NF}' /tmp/_build.txt
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/dev-guide
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/glossary
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/include
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/installation
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/phk
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/reference
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/tutorial
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/users-guide
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/vcl-design-patterns
drwxr-xr-x varnish-trunk/_build/sub/doc/sphinx/whats-new
dr-x------ varnish-trunk/_build/sub/varnish-trunk/doc/sphinx/dev-guide
drwxr-xr-x varnish-trunk/_build/sub/varnish-trunk/doc/sphinx/include

The only other sub-directory that was created under varnish-trunk/_build/sub/varnish-trunk/ is include/ and it got the expected permissions. This directories are copied sequentially in a shell for loop, and dev-guide/ is the first directory in $(EXTRA_DIST). How did include/ show up first? Not via the offending cp -fpR, it is empty. Possibly because of the generated includes.

Is this racing with another target? It shouldn't since distdir-am appears to be called recursively (and not indirectly via the distdir target).

This one appears to be resolved, so either something changed on the archlinux side, or the docker setup part of #4063 made the race go away.
