worker segfault & avfs split bug #59

Closed attuska closed 4 years ago

attuska commented 4 years ago
  1. Az avfs hasítása hibás, mert felrántja a glibc-dev -et is! Ez kiküszöbölhető könnyedén, de mit sem használ, mert az avfs egyedül a worker-nek kellene, az meg hibás.
  2. A worker szegmentációs hibával nem indul. Akkor sem, ha az avfs a fuse2 -vel van fordítva. a worker -O0 opimatizációval történt fordítása esetén is.

Csak az avfs downgrade és azzal a worker újraforgatása rakta rendbe. https://github.com/uhulinux/ub-ubk3/commit/1cc8bfc84ae8d84e3a4a74cad5c954029665bd82 https://github.com/uhulinux/ub-ubk3/commit/3b991197f073af571b962a09d8ea831af5298c1b
