Release Notes

Python Scripting

This updated version of GDB introduces the new Python API, allowing GDB to be automated using

scripts written in the Python Programming Language.

One notable feature of the Python API is the ability to format GDB output (normally referred to as

pretty-printing) using Python scripts. Previously, pretty-printing in GDB was configured using a

standard set of print settings. The ability to create custom pretty-printer scripts gives the user control

of the way GDB displays information for specific applications. Red Hat Enterprise Linux features a

complete suite of pretty-printer scripts for the GNU Standard C++ Library (libstdc++).

Enhanced C++ Support

Support for the C++ programming language in GDB has been improved. Notable improvements

include:

• Better handling of type names.

• Many improvements to expression parsing.

• The need for extraneous quoting has nearly been eliminated

• "next" and other stepping commands work properly even when the inferior throws an exception.

• GDB has a new "catch syscall" command. This can be used to stop the inferior whenever it makes a

system call.

Independent Thread Debugging

Thread execution now permits debugging threads individually and independently of each other;

enabled by new settings "set target-async" and "set non-stop".

14. Interoperability

14.1. Samba

Samba is a suite of programs which use NetBIOS over TCP/IP (NetBT) to enable the sharing of files,

printers and other information. This package provides a Server Message Block or SMB server (also

known as a Common Internet File System or CIFS server) which can provide network services to

SMB/CIFS clients.

Red Hat Enterprise Linux 6 provides the following significant enhancements to Samba:

• Internet Protocol version 6 support (IPv6)

• Support for Windows 2008 (R2) trust relationships.

• Support for Windows 7 domain members.

• Support for Active Directory LDAP signing/sealing policy.

• Improvements for libsmbclient

• Better support for Windows management tools (mmc and User Manager)

• Automatic machine password changes as domain member

• New registry based configuration layer
