System information

The routine printf() now supports vector format specifiers. (r. 2911015).

uudecode now will set execute bits on its output file if they are present in its uuencoded input. It will still not set

sticky bits nor set-id bits. (r. 2910030).

The Ruby scripting language is now installed with Mac OS X. (r. 2809964).

ntpd v4.1.71 is now installed with Mac OS X. (r. 2809093).

The routines inet_pton() and inet_ntop() have been added to Libc. (r. 2372291).

The curses library has been updated to the newer ANSI compliant ncurses library, which supports color and other

advanced text attributes as well as offering greatly increased compatibility with applications which rely on having

a standards-compliant curses library. One side effect of this change is that ALL APPLICATIONS WHICH USE CURSES

MUST BE RELINKED since ncurses is not backwards-compatible with the older version of curses that was shipped

in 10.1. The libncurses library is also now available separately from libSystem in order to minimize the memory

footprint of other applications which do not use curses, so applications using curses must explicitly link with

-lncurses. .

The default aliases and tab-expansion settings for tcsh have reverted to their factory defaults due to various

complaints with the previous highly-customized set of defaults shipped with 10.1 which made using tcsh different

under Mac OS X than on any other Unix platform. Users wishing to have some or all of these defaults back again are

urged to investigate /usr/share/examples/tcsh/README .

Carbon

Carbon is a set of programming interfaces for use in Mac OS applications, especially those being ported from Mac OS 9 to

Mac OS X. Carbon includes about 70 percent of the legacy Mac OS APIs and a number of new APIs for Mac OS X.

Alias Manager

The Alias Manager is the part of the operating system that communicates with the file system to maintain alias records that

are used to keep track of file and folder locations. The Alias Manager does not create Finder alias files; the Finder creates

these files and stores alias records created by the Alias Manager in them.

Aliases to mounted disk image volumes now reference the .img file. As a result, the disk image will be mounted

when the alias is resolved with appropriate mount flags. (r. 2783427).

Alias resolution now does a more thorough job of matching aliases, especially in cases where similar files can be

found on different volumes with the same name. (r. 2776704).

Two new APIs, FSMatchAlias and FSMatchAliasNoUI, have been introduced that provide FSRef based functionality

similar in function to the older MatchAlias routine. (r. 2744821).

A problem where ResolveAlias was incorrectly resolving minimal aliases on volumes that do not natively support

FileIDs has been corrected. (r. 2988555).

A new API, FSCopyAliasInfo, has been added that allows callers to retrieve detailed information from alias records.

(r. 2714855).

Alias resolution now begins with attempting to resolve the file path name first before attempting to resolve the

alias using the file id. This is a fundamental change in the way aliases are resolved and it corrects a problem that

would prevent aliases from working as expected on volumes restored from a back up copy. New flags have been

added to specify the previous behavior (where the file id would be tried first). Pass kARMTryFileIDFirst to calls

which accept a rulesMask or kResolveAliasTryFileIDFirst to calls which accept mountFlags to specify the file id

first behavior. (r. 2683228).

Appearance Manager

The Appearance Manager extends the facilities provided by the Control Manager, the Dialog Manager, the Menu Manager,

and the Window Manager to provide a consistent look and feel for all on screen user interface elements in the Mac OS

environment.

The new constants kThemeSystemFontDetail, kThemeSystemFontDetailEmphazid, kThemeTextColorSystemDetail

have been added in Apperance.h. (r. 2818428).
