Description Denis Descheneaux 2017-03-26 12:46:30 UTC

sys-fs/btrfs-progs-4.10 breaks app-backup/snapper

snapper affected includes -9999 version

snapper: symbol lookup error: /usr/lib64/libbtrfs.so.0: undefined symbol: __error

Downgrading + masking sys-fs/btrfs-progs-4.10 fixes the issue

snapper --version
snapper 0.4.4
flags btrfs,lvm,ext4,xattrs,rollback,btrfs-quota,no-selinux

Please attach a full build log.

Oh, I see. This is runtime breakage due to missing symbols.

This should be reported to the developers upstream.

Ugh. My apologies!

Not the first time I've pushed broken libbtrfs.

Assuming unresolved __error is an omission
(and not the way one supposed to override error implementation)
pushed the fix for snapper as btrfs-progs-4.10-r1 bump:

    https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=a061e9c01024a2b9890cacb0a159e646463553bb

While at it added missing 'sizes.h' header. Will send out
the same patches upstream shortly.

and was released as 4.10.2. I've pushed a bump as:
    https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=60dd05244af80e39bafe998ca0ee3847ebb7fdfe
