| Summary | 0000635: Clarify that uudecode ignores chmod() errors | ||||
| Description | The description of uudecode states: If the pathname of the file to be produced exists, and the user does not have write permission on that file, uudecode shall terminate with an error. If the pathname of the file to be produced exists, and the user has write permission on that file, the existing file shall be overwritten. I think the intention is that this is meant to override the general rules about error conditions, so that if the file exists and has a different owner, but is writable, uudecode should still overwrite the file (and exit with status zero), even though it can't change the permissions. This is long-standing existing practice. It would be better if the standard were to state explicitly that if uudecode can't change the permissions it is not an error. A minor editorial correction should also be made to "If the pathname of the file to be produced exists", since strictly speaking the pathname itself always exists; the condition should be on whether the pathname resolves to an existing file. | ||||
| Desired Action | Change: If the pathname of the file to be produced exists, and the user does not have write permission on that file, uudecode shall terminate with an error. If the pathname of the file to be produced exists, and the user has write permission on that file, the existing file shall be overwritten. to: If the pathname of the file resolves to an existing file and the user does not have write permission on that file, uudecode shall terminate with an error. If the pathname of the file resolves to an existing file and the user has write permission on that file, the existing file shall be overwritten and, if possible, the mode bits of the file (other than standard output) shall be set as described above; if the mode bits cannot be set, uudecode shall not treat this as an error. | ||||

Interpretation response ------------------------ The standard states that an error has to be raised if the mode change fails, and conforming implementations must conform to this. However, concerns have been raised about this which are being referred to the sponsor. Rationale: ------------- The current standard does not match existing (and desired) behavior. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- Make the suggested changes. |

GNU shar's script will complain, but continue and exit based on any following conditions. > chmod 0644 'shar-1.in' > if test $? -ne 0 > then ${echo} "restore of shar-1.in failed" > fi Leastwise for scripts. The uudecode program itself, on the other hand *WILL* die if (UU_CHMOD(outname, fileno (fp), mode) != 0) { error (0, errno, _("chmod of %s"), outname); return EXIT_FAILURE; } the output file is truncated and no data are written. This has been so for a long time. |
