I think in all of the situations you had to call stat, we already construct the absolute path of the file (sometimes a little later in the code, but it can easily be moved), so this should be easy to fix. Rather than sprinkling portability code throughout notmuch-new, it seems like it would be simpler if this logic were wrapped in a separate function. For example, something along the (completely untested) lines of, static mode_t dirent_type (const struct *entry, const char *abspath) { struct stat statbuf; #ifdef _DIRENT_HAVE_D_TYPE static const mode_t modes[] = { [DT_BLK] = S_IFBLK, [DT_CHR] = S_IFCHR, [DT_DIR] = S_IFDIR, [DT_FIFO] = S_IFIFO, [DT_LNK] = S_IFLNK, [DT_REG] = S_IFREG, [DT_SOCK] = S_IFSOCK }; if (entry->d_type >= 0 && entry->d_type < sizeof(modes)/sizeof(modes[0]) && modes[entry->d_type]) return modes[entry->d_type]; #endif if (stat(abspath, &statbuf) == -1) return -1; return statbuf.st_mode & S_IFMT; } This has the added benefit of correctly handling DT_UNKNOWN, which we currently don't. Instead of taking the absolute path of the file, this could take the absolute path of the containing directory and construct the full path from that and d_name; that would probably be a nicer interface, but it would be redundant computation.
