[ast-developers] [patch] getconf(1) XATTR/SATTR(/ACL) support and cd -@ help text update...

[Roland Mainz]

Hi!

----

Attached (as "astksh20130913_getconf_xattr001.diff.txt") is a small
patch which adds XATTR_*/SATTR_* support to AST getconf(1) and updates
cd --man's help output for -@ to describe the options.

* Notes:
- The patch adds $ getconf ACL_ENABLED path # to getconf(1), too...
mostly for completeness
- XATTR support in getconf(1) is split into user-defineable attributes
(XATTR_*) and system attributes (SATTR_*, they are usually private to
the filesystem).
Use $ getconf XATTR_ENABLED /path/to/file.txt # to test whether the
filesystem for "/path/to/file.txt" supports extended attributes and $
getconf XATTR_EXISTS /path/to/file.txt # to test whether
"/path/to/file.txt" has any user-defineable extended attributes.

Comments/rants/etc. welcome... :-)

----

Bye,
Roland

*tilt*

How long does it take until XATTR support is feature complete in ksh93/AST?

Until the fsattr spec
[http://docs.oracle.com/cd/E19253-01/816-5175/6mbba7f02/index.html]
and the newer version from S11.1 is fully implemented? There isn't
much left to do for libcmd builtins, getconf already has two patches
(keys + fpathconf()) which Glenn forgot to apply, cp -p/mv, chmod -@
and ls - at .

If that all is implemented we're feature-complete for ksh93 and libcmd
builtins. After that AST pax (representing tar+cpio in the fsattr
spec) is the only task to implement left.
