Memory Debugging Tools


The gdb debugger has been extended with new commands that make it easier to track down and fix excessive memory usage within programs and libraries.

This functionality was created by Fedora contributor David Malcolm, and we believe it is unique to Fedora.

Detailed Description

Benefit to Fedora

This feature could be of great use to developers and system administrators: it provides a new way of analyzing how a process uses memory, without requiring advance planning.

It is unique to Fedora (it makes heavy use of the gdb/python integration we have in Fedora), and was developed by a Fedora contributor (who is a Red Hat engineer).


How To Test

User Experience


There's a baseline of functionality that I'm developing on top of Fedora 13's gdb.

Some features require additional work in gdb, which I've filed RFE bugs for. Naturally this will require coordination with gdb to ensure that they land in Fedora 14:

  • RHBZ #610241: RFE: please expose "info symbol ADDRESS" in the python API
  • RHBZ #610249: RFE: notification about changes in the inferior process

Contingency Plan

None necessary, simply remove the package
