From d445c30ea6f9693454ca96bae9089ba8738a6f78 Mon Sep 17 00:00:00 2001 From: Chris Marusich Date: Thu, 4 Jun 2020 23:26:19 -0700 Subject: daemon: Handle EXDEV when moving to trash directory. Fixes . Reported by Stephen Scheck . * nix/libstore/gc.cc (LocalStore::deletePathRecursive): When we try to move a dead directory into the trashDir using rename(2) but it returns an EXDEV error, just delete the directory instead. This can happen in a Docker container when the directory is not on the "top layer". --- nix/libstore/gc.cc | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/nix/libstore/gc.cc b/nix/libstore/gc.cc index 8bc4e01eb0..e1d0765154 100644 --- a/nix/libstore/gc.cc +++ b/nix/libstore/gc.cc @@ -455,7 +455,10 @@ void LocalStore::deletePathRecursive(GCState & state, const Path & path) throw SysError(format("unable to rename `%1%' to `%2%'") % path % tmp); state.bytesInvalidated += size; } catch (SysError & e) { - if (e.errNo == ENOSPC) { + /* In a Docker container, rename(2) returns EXDEV when the source + and destination are not both on the "top layer".
