| Summary | 0000261: Unnecessary restrictions on pax stdin and stdout | ||||
| Description | The STDIN section on the pax page says that when standard input is used in write mode, it "shall be a text file containing a list of pathnames, one per line, without leading or trailing <blank> characters." This has the following problems: 1. Text files (by definition) contain characters, but pathnames can contain byte sequences that do not correspond to any character in the codeset of the current locale. 2. A line (by definition) cannot contain more than LINE_MAX bytes, but pathnames can be longer than LINE_MAX bytes. 3. The pathnames themselves can contain leading or trailing <blank> characters. Thus the stated requirement places unnecessary restrictions on the type of pathnames that can be supplied to pax on stdin. The pax utility should accept any valid pathname on stdin (except, obviously, for pathnames containing newline characters, but that is a separate issue being dealt with elsewhere). There is a related problem at the end of the STDOUT section: "In list mode, standard output shall not be buffered more than a line at a time." This means that pathnames longer than LINE_MAX bytes cannot be output using a single write operation, but must be split into chunks of LINE_MAX bytes or fewer. Again, this is an unnecessary restriction. | ||||
| Desired Action | At line 99595 change It shall be a text file containing a list of pathnames, one per line, without leading or trailing <blank> characters. to It shall be a file containing a list of pathnames, each terminated by a <newline> character. At line 99655 change In list mode, standard output shall not be buffered more than a line at a time. to In list mode, standard output shall not be buffered more than a pathname (plus any associated information and a <newline> terminator) at a time. | ||||
