{{Short description|Low-level debugger}}

The '''modular debugger''' ('''mdb''') is an extensible, low-level debugger developed by [[Sun Microsystems]] for the [[Solaris (operating system)|Solaris]] 7 operating system. It is now open sourced, under the [[Common Development and Distribution License]] (CDDL).

It'sIts source code is now available in all open source derivatives of Solaris, such as [[Illumos]].<ref>{{cite web|url=http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/mdb/common/mdb/|title=mdb source in Illumos}}</ref>

==History==

The mdb project was started in 1997 by [[Mike Shapiro (programmer)|Mike Shapiro]] and others when the Solaris operating system was adding support for 64-bit architectures. Up until that point, Solaris was using the aging [[Advanced Debugger|adb]] debugger developed by [[Steve Bourne]] (initially for the[[Seventh AT&TEdition SVR4 Unix distributionUNIX]]<ref>{{man|1|adb|v7}}</ref>).

It was very difficult to simply port adb from a 32-bit architecture to a 64-bit architecture, so Sun engineers decided to make a new debugger that would feature enhanced debugging capabilities, while being backward compatible with adb.
