4GDB is a collaborative project and one which wants to encourage new
5development.  You may wish to fix GDB bugs, improve testing, port GDB
6to a new platform, update documentation, add new GDB features, and the
7like. To help with this, there is a lot of documentation
8available.. In addition to the user guide and internals manual
9included in the GDB distribution, the GDB web pages also contain much
10information.
11
12You may also want to submit your change so that can be considered for
13conclusion in a future version of GDB (see below).  Regardless, we
14encourage you to distribute the change yourself.
15
16If you don't feel up to hacking GDB, there are still plenty of ways to
17help!  You can answer questions on the mailing lists, write
18documentation, find bugs, create a GDB related website (contribute to
19the official GDB web site), or create a GDB related software
20package. We welcome all of the above and feel free to ask on the GDB
21mailing lists if you are looking for feedback or for people to review
22a work in progress.

26Finally, there are certain legal requirements and style issues which
27all contributors need to be aware of.
28
29o	Coding Standards
30
31	All contributions must conform to the GNU Coding Standard.
32	Submissions which do not conform to the standards will be
33	returned with a request to reformat the changes.
34
35	GDB has certain additional coding requirements.  Those
36	requirements are explained in the GDB internals documentation
37	in the gdb/doc directory.
38
39	Ref: http://www.gnu.org/prep/standards_toc.html

41
42o	Copyright Assignment
43
44	Before we can accept code contributions from you, we need a
45	copyright assignment form filled out and filed with the FSF.
46
47	See some documentation by the FSF for details and contact us
48	(either via the GDB mailing list or the GDB maintainer that is
49	taking care of your contributions) to obtain the relevant
50	forms.
51
52	Small changes can be accepted without a copyright assignment form on file.
53
54	Ref: http://www.gnu.org/prep/maintain.html#SEC6

56
57o	Submitting Patches
58
59	Every patch must have several pieces of information before we
60	can properly evaluate it.
61
62	A description of the bug and how your patch fixes this
63	bug. A reference to a testsuite failure is very helpful. For
64	new features a description of the feature and your
65	implementation.
66
67	A ChangeLog entry as plaintext (separate from the patch); see
68	the various ChangeLog files for format and content. Note that,
69	unlike some other projects, we do require ChangeLogs also for
70	documentation (i.e., .texi files).
71
72	The patch itself. If you are accessing the CVS repository use
73	"cvs update; cvs diff -cp"; else, use "diff -cp OLD NEW" or
74	"diff -up OLD NEW". If your version of diff does not support
75	these options, then get the latest version of GNU diff.
76
77	We accept patches as plain text (preferred for the compilers
78	themselves), MIME attachments (preferred for the web pages),
79	or as uuencoded gzipped text.
80
81	When you have all these pieces, bundle them up in a mail
82	message and send it to gdb-patches@sourceware.org. All
83	patches and related discussion should be sent to the
84	gdb-patches mailinglist. For further information on the GDB
85	CVS repository, see the Anonymous read-only CVS access and
86	Read-write CVS access page.

90Supplemental information for GDB:
91
92o	Please try to run the relevant testsuite before and after
93	committing a patch
94
95	If the contributor doesn't do it then the maintainer will.  A
96	contributor might include before/after test results in their
97	contribution.
98
99
100o	For bug fixes, please try to include a way of
101	demonstrating that the patch actually fixes something.
102
103	The best way of doing this is to ensure that the
104	testsuite contains one or more test cases that
105	fail without the fix but pass with the fix.
106
107	People are encouraged to submit patches that extend
108	the testsuite.
109
110
111o	Please read your patch before submitting it.
112
113	A patch containing several unrelated changes or
114	arbitrary reformats will be returned with a request
115	to re-formatting / split it.
116
117
118o	If ``gdb/configure.in'' is modified then you don't
119	need to include patches to the regenerated file
120	``configure''.
121
122	The maintainer will re-generate those files
123	using autoconf (2.13 as of 2000-02-29).
124
125
126o	If ``gdb/gdbarch.sh'' is modified, you don't
127	need to include patches to the generated files
128	``gdbarch.h'' and ``gdbarch.c''.
129
130	See ``gdb/configure.in'' above.
131
132
133o	When submitting a patch that fixes a bug
134	in GDB's bug database a brief reference
135	to the bug can be included in the ChangeLog
136	vis
137
138	* CONTRIBUTE: Mention PR convention.
139	Fix PR gdb/4705.
140
141	The text ``PR gdb/4705'' should also be included
142	in the CVS commit message.  That causes the
143	patch to automatically be archived with the PR.
