if the sieve script being compiled has read-only permissions, using save_mode in sieve_storage_setup_bin_path will cause the created directory to have permission bits 0555 (executable bit added by mkdir_get_executable_mode), resulting in pigeonhole being unable to save the compiled sieve binary

I wonder if we should instead create a new mkdir_get_wx_mode() that adds +w and +x bits for every +r. @stephanbosch do you remember if there's a reason we want to get the mode from the sieve script rather than hardcoding to 0700?

No. Likely, this code is borrowed from core/lib-storage somewhere.

@sirainen thank you for the review, do you think this patch would gain more traction on the dovecot mailing list? If so I can try submitting it there |

This patch fixes a permission issue that occurs when saving compiled sieve scripts sourced from the nix store. Instead of reusing the read-only permission bits from the nix store, it explicitly uses `0700` for the directory in which compiled sieve scripts should be saved.

When a sieve script is saved as read-only, calling
sieve_storage_setup_bin_pathwithmkdir_get_executable_mode(save_mode)where - if I understand everything correctly -save_modeis derived from the original sieve script's permissions, will result in a read-only (technically0555,mkdir_get_executable_modeadds the executable bit) storage directory. This will cause pigeonhole to fail when saving the compiled script, as the directory has permissions0555:Explicitly using
0700when callingsieve_storage_setup_bin_pathfixes this.Extra context:
