On macOS BigSur, the sandbox-exec command behaves slightly different than on Catalina when firm links are present. Resolving symlinks can prevent the sandbox for allowing write operations to the sandbox base. This effectively reverts a piece of 656a0ba on macOS, namely: > When using --experimental_sandbox_base, ensure that symlinks in the path are > resolved. Before this, you had to check whether on your system /dev/shm is a > symlink to /run/shm and then use that instead. Now it no longer matters, as > symlinks are resolved. but I think this is okay since macOS doesn't have /dev/shm or /run. See bazelbuild#13766 for full details.

@Wyverald I think this should go in a 5.x release. |

(I realize that this is closed -- I'm still keeping track of it for 5.1 -- I'm trying a few things and seeing what's best for release management) |
