--- Begin Message ---Package: moreutils Version: 0.47 Severity: normal Dear Maintainer, I have found what seems to be a bug in "sponge", which does not propagate the write error when writing to its output file, failing silently. * What led up to the situation? $ echo | sponge /dev/full && echo OK OK * What exactly did you do (or not do) that was effective (or ineffective)? * What was the outcome of this action? It could not obviously write to /dev/full, but returned EXIT_SUCESS. * What outcome did you expect instead? I would expect it to return a non-zero return value and a message. * Debug details $ echo | strace sponge /dev/full [...] open("/dev/full", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4 lseek(3, 0, SEEK_SET) = 0 read(3, "\n", 8192) = 1 fstat(4, {st_mode=S_IFCHR|0666, st_rdev=makedev(1, 7), ...}) = 0 ioctl(4, SNDCTL_TMR_TIMEBASE or TCGETS, 0x7fff7e925e80) = -1 ENOTTY (Inappropriate ioctl for device) mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f8e389b8000 read(3, "", 8192) = 0 close(3) = 0 munmap(0x7f8e389b9000, 4096) = 0 write(4, "\n", 1) = -1 ENOSPC (No space left on device) close(4) = 0 munmap(0x7f8e389b8000, 4096) = 0 rt_sigprocmask(SIG_BLOCK, [HUP INT QUIT PIPE ALRM TERM XCPU XFSZ VTALRM PROF IO], [], 8) = 0 unlink("/tmp/sponge.wsOZkV") = 0 rt_sigprocmask(SIG_SETMASK, [], NULL, 8) = 0 exit_group(0) = ? [...] As you can see, the write() fails but the error is not propagated. I think this issue is potentially (although remotely probably) serious since sponge lends itself to be used to automatically edit files, but it will thrash them if the concerning filesystem happens to become full during the editing. Thank you.
