Project/Component Working Name: Remove /usr/bin/printf from PSARC case 2008 094 1.2. Name of Document Author/Supplier: Author: Donald Cragun 1.3 Date of This Document: 17 September, 2008 4. Technical Description This case updates PSARC/2008/094 (ksh93 Update 1). While implementing PSARC/2008/094, which (among other things) planned to replace /usr/bin/printf with a link to the AT&T AST printf, the project team found some irregularities in standards conformance in both the default printf() function in libc and in the behavior of /usr/bin/printf. Since some of these issues may involve official interpretation requests against the POSIX Standards and the Single UNIX Specifications, they may take a long time to resolve. Therefore, this case removes the changes to /usr/bin/printf that were documented in PSARC/2008/094 from the deliverables provided by that case so PSARC/2008/094 changes can be integrated in a timely manner. Since the current /usr/bin/printf will not be changed by this case, there are no backwards compatibility issues. 6. Resources and Schedule 6.4. Steering Committee requested information 6.4.1.

The problem is that we don't have time anymore for _any_ discussions around the /usr/bin/printf since the code for PSARC/2008/094 must be ready by Friday (_last_ _date_). > That said, out of curiosity, where do the implementations differ such > that ksh93's s/ksh93/AST/ , ksh93 only offers the AST version of "printf" as builtin command > version can't stand as a replacement? It's the "precision" option of "%s" - does it count in "whole charatcers" (where "character" means "multi-byte character" (like all other ksh88/ksh93/bash2/bash3 string operators do)), "screen columns" (since _some_ multibyte characters occupy more than one screen column) or "bytes". The ksh93 builtin originally used "whole characters" but the POSIX/SUS standards indirectly define "bytes" (without having any "leeway" right now to allow "whole characters") and the Solaris command seems to use (accidently ?) "screen columns" (where I doubt whether this makes sense). In the meantime the ksh93 builtin has been changed to use "bytes" as defined by POSIX/SUS and we're now trying to investigate two things: 1. Why Solaris's /usr/bin/printf uses "screen columns" ? 2. How can we get a |printf()| formatting option for "whole characters" ("%s"'s precision option counting in bytes isn't very healthy for multibyte characters) ? We're currently digging around to get an answer for [1] but we don't have _any_ time anymore to hold-off the other parts of PSARC/2008/094 for that - people need the updated/fixed ksh93 _BADLY_, preferable checked-in yesterday or the day before that. ---- Bye, Roland -- __ . . __ (o.\ \/ /.o) roland.mainz@nrubsig.org \__\/\/__/ MPEG specialist, C&&JAVA&&Sun&&Unix programmer /O /==\ O\ TEL +49 641 3992797 (;O/ \/ \O;)
