I'm sponsoring this fast-track request on behalf of April Chin and the
ksh93 project team. Please note that this is an *open* case.
The release binding is the same as with the previous ksh93 project: a
patch/micro release of Solaris delivering through ON. ksh93 has not
yet delivered into any release of Solaris. Stability levels are as
described below.
Additional materials (man pages and diffs) can be found in the
'materials' subdirectory.
This project is an amendment to the Korn Shell 93 Integration project
(PSARC/2006/550) specifying the following additional interfaces:
1) a ksh93 built-in getconf command and
2) AT&T components for building message files for localization
Bug/RFE Number(s):
6505835 AST tools and library (libpp) required for creating l10n messages
for ksh93
Description
The AT&T built-in version of the getconf utility in ksh93 contains
extensions not present in the Solaris getconf utility, which are
required to run the AT&T ksh93 tests; these tests are critical to the
verification of ksh93 builds. The getconf built-in allows users to
write ksh93 scripts which are portable across different systems and
which can take advantage of AT&T extensions to ksh93 [1,2].
Like other built-in commands named in PSARC/2006/550, the getconf
built-in in ksh93 will be bound to the /bin pathname. The built-in
getconf in ksh93 will only be invoked if called with no pathname
prefix, and if a /bin/getconf or /usr/bin/getconf executable is found
first on the user's path.
The stability of the getconf built-in command-line interface and the
system variables documented in getconf(1) is Committed; its pathname
binding to /bin is Volatile. The getconf built-in supports additional
system variables not available for /usr/bin/getconf; these variables
are Project Private, and include names prefixed with "AST" and "_AST".
All options and system variables supported by /usr/bin/getconf produce
identical output values using the ksh93 built-in getconf. Additions
to the ksh93 test suite and to /usr/bin/getconf testing will ensure
that ksh93 built-in getconf continues to provide functionality
compatible with /usr/bin/getconf.
The second portion of this project specifies the addition of AT&T
message-building components--a library, ksh93 scripts, and a set of
binaries--required for the ksh93 project to build its message files
for localization.
The message-building tools and proposed AT&T library, libpp, have a
strong dependency on libast, one of the new AT&T libraries specified
in PSARC/2006/550. Therefore these components should be kept in sync
with libast on Solaris.
These components will initially be used only by the Korn Shell 93
Integration Project (PSARC/2006/550). The proposed location of the
tools in /usr/ast/bin is consistent with the location used within
AT&T.
If the interface stability level of the shared libraries listed in
PSARC/2006/550 (libshell, libast, libdll, and libcmd) is promoted from
Project Private, the stability of the /usr/ast/bin components listed
below should be promoted to at least the same level, to allow
consumers of the former to build the appropriate message files.
Interface Description Stability
--------- ----------- ---------
/usr/lib/libpp.so.1 AT&T ANSI C preprocessor library Project Private
/usr/ast/bin directory for AT&T commands Volatile
/usr/ast/bin/msgadmin ksh93 script for message catalog Volatile
file administration
/usr/ast/bin/msgcc ksh93 script for generating message Volatile
catalog files
binaries used by msgcc and msgadmin
for message formatting, converting:
/usr/ast/bin/msgcpp Volatile
/usr/ast/bin/msgcvt Volatile
/usr/ast/bin/msggen Volatile
/usr/ast/bin/msgget Volatile
A new package for AST (Advanced Software Technology) developer tools,
SUNWastdev, will be created, which includes all of the above
message-building components. These tools have a dependency on ksh93
and its libraries, as listed in PSARC/2006/550, and shall not be
integrated before the Korn Shell 93 Integration project.
Dynamic library dependencies of msgcpp, msgcvt, msggen, and msgget:
libpp.so.1 => /usr/lib/libpp.so.1
libast.so.1 => /usr/lib/libast.so.1
libm.so.2 => /lib/libm.so.2

libmd.so.1 => /usr/lib/libmd.so.1
libscf.so.1 => /usr/lib/libscf.so.1
libuutil.so.1 => /usr/lib/libuutil.so.1
