		GDB Maintainers
		===============


		   Overview
		   --------

This file describes different groups of people who are, together, the
maintainers and developers of the GDB project.  Don't worry - it sounds
more complicated than it really is.

There are four groups of GDB developers, covering the patch development and
review process:

  - The Global Maintainers.

    These are the developers in charge of most daily development.  They
    have wide authority to apply and reject patches, but defer to the
    Responsible Maintainers (see below) within their spheres of
    responsibility.

  - The Responsible Maintainers.

    These are developers who have expertise and interest in a particular
    area of GDB, who are generally available to review patches, and who
    prefer to enforce a single vision within their areas.

  - The Authorized Committers.

    These are developers who are trusted to make changes within a specific
    area of GDB without additional oversight.

  - The Write After Approval Maintainers.

    These are developers who have write access to the GDB source tree.  They
    can check in their own changes once a developer with the appropriate
    authority has approved the changes; they can also apply the Obvious
    Fix Rule (below).

All maintainers are encouraged to post major patches to the gdb-patches
mailing list for comments, even if they have the authority to commit the
patch without review from another maintainer.  This especially includes
patches which change internal interfaces (e.g. global functions, data
structures) or external interfaces (e.g. user, remote, MI, et cetera).

The term "review" is used in this file to describe several kinds of feedback
from a maintainer: approval, rejection, and requests for changes or
clarification with the intention of approving a revised version.  Review is
a privilege and/or responsibility of various positions among the GDB
Maintainers.  Of course, anyone - whether they hold a position but not the
relevant one for a particular patch, or are just following along on the
mailing lists for fun, or anything in between - may suggest changes or
ask questions about a patch!

There's also a couple of other people who play special roles in the GDB
community, separately from the patch process:

  - The GDB Steering Committee.

    These are the official (FSF-appointed) maintainers of GDB.  They have
    final and overriding authority for all GDB-related decisions, including
    anything described in this file.  The committee is not generally
    involved in day-to-day development (although its members may be, as
    individuals).

  - The Release Manager.

    This developer is in charge of making new releases of GDB.

  - The Patch Champions.

    These volunteers make sure that no contribution is overlooked or
    forgotten.

Most changes to the list of maintainers in this file are handled by
consensus among the global maintainers and any other involved parties.
In cases where consensus can not be reached, the global maintainers may
ask the Steering Committee for a final decision.


			The Obvious Fix Rule
			--------------------

All maintainers listed in this file, including the Write After Approval
developers, are allowed to check in obvious fixes.

An "obvious fix" means that there is no possibility that anyone will
disagree with the change.

A good mental test is "will the person who hates my work the most be
able to find fault with the change" - if so, then it's not obvious and
needs to be posted first. :-)

Something like changing or bypassing an interface is _not_ an obvious
fix, since such a change without discussion will result in
instantaneous and loud complaints.


	     GDB Steering Committee
	     ----------------------

The members of the GDB Steering Committee are the FSF-appointed
maintainers of the GDB project.

The Steering Committee has final authority for all GDB-related topics;
they may make whatever changes that they deem necessary, or that the FSF
requests.  However, they are generally not involved in day-to-day
development.

The current members of the steering committee are listed below, in
alphabetical order.  Their affiliations are provided for reference only -
their membership on the Steering Committee is individual and not through
their affiliation, and they act on behalf of the GNU project.

	Jim Blandy (CodeSourcery)
	Andrew Cagney (Red Hat)
	Robert Dewar (AdaCore, NYU)
	Klee Dienes (Apple)
	Paul Hilfinger (UC Berkeley)
	Dan Jacobowitz (CodeSourcery)
	Stan Shebs (Apple)
	Richard Stallman (FSF)
	Ian Lance Taylor (C2)
	Todd Whitesel


		  Global Maintainers
		  ------------------

The global maintainers may review and commit any change to GDB, except in
areas with a Responsible Maintainer available.  For major changes, or
changes to areas with other active developers, global maintainers are
strongly encouraged to post their own patches for feedback before
committing.

The global maintainers are responsible for reviewing patches to any area
for which no Responsible Maintainer is listed.

Global maintainers also have the authority to revert patches which should
not have been applied, e.g. patches which were not approved, controversial
patches committed under the Obvious Fix Rule, patches with important bugs
that can't be immediately fixed, or patches which go against an accepted and
documented roadmap for GDB development.  Any global maintainer may request
the reversion of a patch.  If no global maintainer, or responsible
maintainer in the affected areas, supports the patch (except for the
maintainer who originally committed it), then after 48 hours the maintainer
who called for the reversion may revert the patch.

No one may reapply a reverted patch without the agreement of the maintainer
who reverted it, or bringing the issue to the GDB Steering Committee for
discussion.

At the moment there are no documented roadmaps for GDB development; in the
future, if there are, a reference to the list will be included here.

The current global maintainers are (in alphabetical order):

Jim Blandy			jimb@codesourcery.com
Kevin Buettner			kevinb@redhat.com
Andrew Cagney			cagney@gnu.org
Fred Fish			fnf@ninemoons.com
Daniel Jacobowitz		dan@debian.org
Mark Kettenis           	kettenis@gnu.org
Stan Shebs			shebs@apple.com
Michael Snyder			msnyder@redhat.com
Elena Zannoni			ezannoni@redhat.com
Eli Zaretskii			eliz@gnu.org


			Release Manager
			---------------

The current release manager is: Joel Brobecker  <brobecker@adacore.com>

His responsibilities are:

    * organizing, scheduling, and managing releases of GDB.

    * deciding the approval and commit policies for release branches,
      and can change them as needed.


			Patch Champions
			---------------

These volunteers track all patches submitted to the gdb-patches list.  They
endeavor to prevent any posted patch from being overlooked; work with
contributors to meet GDB's coding style and general requirements, along with
FSF copyright assignments; remind (ping) responsible maintainers to review
patches; and ensure that contributors are given credit.

Current patch champions (in alphabetical order):

	Randolph Chung     <tausq@debian.org>
	Daniel Jacobowitz  <dan@debian.org>


			Responsible Maintainers
			-----------------------

These developers have agreed to review patches in specific areas of GDB, in
which they have knowledge and experience.  These areas are generally broad;
the role of a responsible maintainer is to provide coherent and cohesive
structure within their area of GDB, to assure that patches from many
different contributors all work together for the best results.

Global maintainers will defer to responsible maintainers within their areas,
as long as the responsible maintainer is active.  Active means that
responsible maintainers agree to review submitted patches in their area
promptly; patches and followups should generally be answered within a week.
If a responsible maintainer is interested in reviewing a patch but will not
have time within a week of posting, the maintainer should send an
acknowledgement of the patch to the gdb-patches mailing list, and
plan to follow up with a review within a month.  These deadlines are for
initial responses to a patch - if the maintainer has suggestions
or questions, it may take an extended discussion before the patch
is ready to commit.  There are no written requirements for discussion,
but maintainers are asked to be responsive.

If a responsible maintainer misses these deadlines occasionally (e.g.
vacation or unexpected workload), it's not a disaster - any global
maintainer may step in to review the patch.  But sometimes life intervenes
more permanently, and a maintainer may no longer have time for these duties.
When this happens, he or she should step down (either into the Authorized
Committers section if still interested in the area, or simply removed from
the list of Responsible Maintainers if not).

If a responsible maintainer is unresponsive for an extended period of time
without stepping down, please contact the Global Maintainers; they will try
to contact the maintainer directly and fix the problem - potentially by
removing that maintainer from their listed position.

If there are several maintainers for a given domain then any one of them
may review a submitted patch.

Target Instruction Set Architectures:

The *-tdep.c files.  ISA (Instruction Set Architecture) and OS-ABI
(Operating System / Application Binary Interface) issues including CPU
variants.

The Target/Architecture maintainer works with the host maintainer when
resolving build issues.  The Target/Architecture maintainer works with
the native maintainer when resolving ABI issues.

All developers recognized by this file can make arbitrary changes to
OBSOLETE targets.

The Bourne shell script gdb_mbuild.sh can be used to rebuild all the
above targets.


Host/Native:

The Native maintainer is responsible for target specific native
support - typically shared libraries and quirks to procfs/ptrace/...
The Native maintainer works with the Arch and Core maintainers when
resolving more generic problems.

The host maintainer ensures that gdb can be built as a cross debugger on
their platform.

		Authorized Committers
		---------------------

These are developers working on particular areas of GDB, who are trusted to
commit their own (or other developers') patches in those areas without
further review from a Global Maintainer or Responsible Maintainer.  They are
under no obligation to review posted patches - but, of course, are invited
to do so!
