---------------------------------------------------------------------- (0005857) geoffclare (manager) - 2022-06-21 09:16 https://austingroupbugs.net/view.php?id=1538#c5857 ---------------------------------------------------------------------- Suggested new resolution (note that bug https://austingroupbugs.net/view.php?id=1563 already fixed STDOUT, so this should just be about -s) ... Interpretation response ------------------------ The standard is unclear on this issue, and no conformance distinction can be made between alternative implementations based on this. This is being referred to the sponsor. Rationale: ------------- The use of the word "quit" can be interpreted as allowing <i>what</i> to exit without processing later files, whereas the intention is that it skips to the next file. Notes to the Editor (not part of this interpretation): ------------------------------------------------------- On page 3437 line 116032 section what, after applying bug 1563 change:<blockquote>The <i>what</i> utility shall write to standard output what follows until the first occurrence ...</blockquote>to:<blockquote>The <i>what</i> utility shall write to standard output the identification string that follows up to, but not including, the first occurrence ...</blockquote> On page 3437 line 116038 section what (-s option), change:<blockquote>Quit after finding the first occurrence of the pattern in each file.</blockquote>to:<blockquote>Write at most one identification string for each file. After locating and writing to standard output the identification string following the first pattern (if any) in a file, no further data shall be read from that file and the search shall recommence from the beginning of the next file, if any</blockquote> On page 3438 line 116099 section what, change RATIONALE from:<blockquote>None.</blockquote>to:<blockquote>The standard requires that when the <b>-s</b> option is used, <i>what</i> does not continue reading from the current file after writing the first identification string. This might seem an unimportant detail, but applications would experience different behavior if a <i>file</i> operand names a FIFO special file and <i>what</i> waited for an end-of-file condition rather than closing the file straight away.</blockquote> Issue History Date Modified Username Field Change ====================================================================== 2021-12-05 06:48 andras_farkas New Issue 2021-12-05 06:48 andras_farkas Name => Andras Farkas 2021-12-05 06:48 andras_farkas Section => what 2022-02-17 09:02 Don Cragun Page Number => 3437 2022-02-17 09:02 Don Cragun Line Number => 116041 2022-02-17 09:02 Don Cragun Interp Status => --- 2022-02-17 15:57 geoffclare Note Added: 0005674 2022-02-17 17:00 geoffclare Note Added: 0005675 2022-02-17 17:02 geoffclare Final Accepted Text => https://austingroupbugs.net/view.php?id=1538#c5675 2022-02-17 17:02 geoffclare Status New => Interpretation Required 2022-02-17 17:02 geoffclare Resolution Open => Accepted As Marked 2022-02-17 17:03 geoffclare Interp Status --- => Pending 2022-02-17 17:03 geoffclare Tag Attached: tc3-2008 2022-02-18 09:14 kre Note Added: 0005680 2022-02-18 09:39 geoffclare Note Added: 0005681 2022-02-18 14:39 andras_farkas Note Added: 0005682 2022-02-18 15:07 andras_farkas Note Added: 0005683 2022-02-18 19:20 kre Note Added: 0005687 2022-02-18 19:27 kre Note Added: 0005688 2022-03-25 17:08 agadmin Interp Status Pending => Proposed 2022-03-25 17:08 agadmin Note Added: 0005764 2022-04-26 11:08 geoffclare Note Added: 0005821 2022-06-20 15:02 kre Note Added: 0005854 2022-06-20 15:17 kre Note Edited: 0005854 2022-06-20 16:57 kre Note Edited: 0005854 2022-06-20 17:00 kre Note Edited: 0005854 2022-06-21 08:54 geoffclare Relationship added related to 0001563 2022-06-21 09:16 geoffclare Note Added: 0005857 ======================================================================
