Gdb Debugger Internals

Every now and then I dig into PHP internals with gdb, typically to debug issues with the Gearman Pecl extension as I'm currently primary maintainer for the project. It's a fairly low time demand, despite the handful of issues lingering at the moment, so I'll poke at it maybe 3 or 4 times a year since completing the migration to PHP 7 and adding some tests in 2015.

The documentation is also available for download in a number of different formats including HTML, DVI, PS and PDF.

1. Overview In this article we will use GDB debugger to trace the internals of Postgres and observe how an input query passes through several levels of transformation Parser -gt Analyzer -gt Rewriter -gt Planner -gt Executor and eventually produces an output. This article is based on PG12 running on Ubuntu 18.04, and we will

Check out the GDB Internals Manual, which covers some of the important aspects. There's also an older PDF version of this document. From the manual This document documents the internals of the GNU debugger, gdb. It includes description of gdb's key algorithms and operations, as well as the mechanisms that adapt gdb to specific hosts and targets.

When you run GDB in the GDB source directory, it will read a .gdbinit' file that sets up some simple things to make debugging gdb easier. The info command, when executed without a subcommand in a GDB being debugged by gdb, will pop you back up to the top level gdb.

This document documents the internals of the GNU debugger, GDB. It includes descrip-tion of GDB's key algorithms and operations, as well as the mechanisms that adapt GDB to specic hosts and targets. 1 Requirements Before diving into the internals, you should understand the formal requirements and other expectations for GDB.

This is the first of a two-part series describing the implementation of a generic debugging tool. Part one covers the core internals of a debugger part two will focus on extending a debugger to support a specific programming language - Go. Implementing a debugging tool may seem like a monumental task. gdb, one of the most popular debuggers, is over 500,000 SLOC according to cloc it's
