    Submitter's Classification Minor System Fault
    State Resolved
    Resolution Minor System Fault (MSF)

    Published 1996-01-09 08:00
    Expiry Date 1997-01-04
    Product Standard Commands and Utilities V2 (UNIX 95)
    Certification Program The Open Brand certification program
    Test Suite VSC version 4.1.4
    Test Identification POSIX.upe/vi 139
    Problem Summary MSF4C.00006 A MSF is requested because '.' does not repeat the 'p' commands.
    Problem Text
    The test in question verifies the assertion:
    When [count] . is entered in command mode, then vi repeats the last
    command that changed the buffer and uses count as the number of
    iterations of the command being repeated. (Default 1 when count not
    specified) The values of current line and column are set as specified by
    the command which is repeated.
    TESTING REQUIREMENT:
    Test for each of the buffer changing commands !, &, <, >, ~,
    a, A, c, C, d, D, i, I, J, o, O, p, P, r, R, s, S, u, U, x and X.

    There is an error in the existing test (recognized by waiver
    #TSD4C.00091) in that some of the expected output files are incorrect.
    However, on our implementation the assertion fails for the "p" and "P"
    commands independently of this error (subtest number 7 in the
    assertion test). This behavior (a failure to repeat a "p" or "P") is
    longstanding; according to Keith Bostic, it is the historical behavior
    of vi. Nevertheless, he views it as a bug, as do POSIX.2-1990, XPG4
    Issue 2, and (draft) POSIX.2b.

    We request a waiver on the grounds that this is a Minor System Fault.
    In support of this request we wish to point out that:
    (a) The current test suite, because of its own bug, does not exhibit
    this failure.
    (b) This is the historical behavior of the vi utility.
    (c) A workaround (using "p" or "P" instead of ".") is always available
    to the user.

    Test Information:
    Assertion #139 (C): count . command
    Note: The testing requirements include testing for the dot and
    ampersand commands. This violates historical practice and may
    be changed in a future revision of POSIX.2, but it remains a
    normative requirement of the current standard.

    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    A temporary waiver for a minor system fault is recommended.

    We believe this issue is minor and limited to interactive use of
    the repeat command (.). Users can work around this by
    re-entering the command sequence again rather than using the .
    as a shortcut.
