Fixes in commit f5a2724ae453f4a4b55ff848f4ad7e30efb6eef8.
For the record, the bug also impacted permissions on these directories,
which were not set to read-only for the owner (it was still read-only
for everyone else, fortunately):
--8<---------------cut here---------------start------------->8---
$ ls -ld /gnu/store/yn7dx3jkb18mc7dwnsn2izix2f62riw8-python-tables-3.4.4/lib/python3.7/site-packages/tables-3.4.4-py3.7.egg-info
drwxr-xr-x 2 root root 4096 Nov 13 00:32 /gnu/store/yn7dx3jkb18mc7dwnsn2izix2f62riw8-python-tables-3.4.4/lib/python3.7/site-packages/tables-3.4.4-py3.7.egg-info/
--8<---------------cut here---------------end--------------->8---
The bug occurred only on directories containing files that were
deduplicated.
(Remember that you’re not exposed at all if you do not use offloading.)
I’ll update the ‘guix’ package so everyone can deploy the fix.
Ludo’.
