Report 1169 Actions Problem Report Number 1169 Submitter's Classification Test Suite problem State Resolved Resolution Rejected (REJ) Problem Resolution ID REJ.X.0371 Raised 1970-01-01 08:00 Updated 2003-03-13 08:00 Published null Product Standard Internationalised System Calls and Libraries Extended (UNIX 95) Certification Program The Open Brand certification program Test Suite VSU version 4.1.0 Test Identification CAPIbase/poll 25 Problem Summary PG4U.00097 This IR claims the test may fail with EPERM errors if the implementation does not support physical tty ports. Problem Text Test cases: base/poll25, base/readv22 The setup of these test cases presumes the existence of physical terminal ports and that the branding user has read and write access to these physical ports. There is no such requirement in the specification for the existence of physical terminals. I reference PG4U.00085 to prove that the test suite is in fact requiring physical terminals or devices for these tests: PG4U.00085: "Section 5.1.4 Terminal Devices, in the User's Guide, describes the requirements for VSU_TERMIOS_LOOP and VSU_TERMIOS_TTY. In all cases VSU_TERMIOS_LOOP and VSU_TERMIOS_TTY are required to be physical ports not pseudo-terminals." The first rationale is a reading of section 5.1.4, p. 29 of the User's guide, August 28, 1995. The only words used to describe VSU_TERMIOS_LOOP and VSU_TERMIOS_TTY are as follows: "The names of the special files for terminal devices" All the other wording pertains to Curses or XCurses tests. Under the main heading, also, the following statement: "The user running VSU must have read and write access for all three terminal devices configured." The words "physical ports" or "physical devices" does not appear. The second and main rationale is that this test cannot require the use of physical terminal ports as these are not part of the standard. The loopback functionality can be demonstrated with a software loopback program but no such program is provided. A loopback terminal cable method is provided for RS-232 asynchronous terminal ports, but such ports are also not required by the standard. In many of the existing test cases the words: "No portable means to induce the condition", or some variant thereof is used. I can think of no better example than the requirement of physical devices in a loopback configuration as a nonportable testing requirement. We are able to use software and pseudo-terminals to demonstrate functionality (a 20 line C program), but we feel that the test and the documentation in Section 5.1.4 of the user's guide is fundamentally flawed.

We agree that the spec does not require an implementation to support physical terminal ports. But, we believe the output above does not match the output one would expect from such an implementation. The EPERM errors indicate that a specified device was present but that there was insufficient privilege to open that device. We believe this is probably a configuration error. If no physical ports exist for an implementation then VSU_TERMIOS_TTY and VSU_TERMIOS_LOOP should be undefined.
