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

26 Finally, there are certain legal requirements and style issues which
27 all contributors need to be aware of.
31 All contributions must conform to the GNU Coding Standard.
32 http://www.gnu.ai.mit.edu/prep/standards_toc.html
33 Submissions which do not conform to the standards will be
34 returned with a request to reformat the changes.
36 For GDB, that standard is more tightly defined. GDB's
37 coding standard is determined by the output of
40 This situation came about because, by the start of '99,
41 GDB's coding style was so bad an inconsistent that it was
42 decided to restart things from scratch.
45 o Copyright Assignment
47 There are certain legal requirements
49 Before we can accept code contributions from you, we need a
50 copyright assignment form filled out.
52 If you've developed some addition or patch to GDB that you
53 would like to contribute, you should fill out a copyright
54 assignment form and send it in to the FSF. We are unable to
55 use code from you until this is on-file at the FSF, so get
56 that paperwork in! This form covers one batch of changes.
57 Ref: http://gcc.gnu.org/fsf-forms/assignment-instructions.html
59 If you think you're going to be doing continuing work on GDB, it
60 would be easier to use a different form, which arranges to
61 assign the copyright for all your future changes to GDB. It is
62 called assign.future. Please note that if you switch
63 employers, the new employer will need to fill out the
64 disclaim.future form; there is no need to fill out the
65 assign.future form again.
66 Ref: http://gcc.gnu.org/fsf-forms/assign.future
67 Ref: http://gcc.gnu.org/fsf-forms/disclaim.future
69 There are several other forms you can fill out for different
70 circumstances (e.g. to contribute an entirely new program, to
71 contribute significant changes to a manual, etc.)
72 Ref: http://gcc.gnu.org/fsf-forms/copyrights.html
74 Small changes can be accepted without a copyright assignment
77 This is pretty confusing! If you are unsure of what is
78 necessary, just ask the GDB mailing list and we'll figure out
81 Note: Many of these forms have a place for "name of
82 program". Insert the name of one program in that place -- in
88 Every patch must have several pieces of information before we
89 can properly evaluate it.
91 A description of the bug and how your patch fixes this
92 bug. A reference to a testsuite failure is very helpful. For
93 new features a description of the feature and your
96 A ChangeLog entry as plaintext (separate from the patch); see
97 the various ChangeLog files for format and content. Note that,
98 unlike some other projects, we do require ChangeLogs also for
99 documentation (i.e., .texi files).
101 The patch itself. If you are accessing the CVS repository at:
102 Cygnus, use "cvs update; cvs diff -c3p"; else, use "diff -c3p
103 OLD NEW" or "diff -up OLD NEW". If your version of diff does
104 not support these options, then get the latest version of GNU
107 We accept patches as plain text (preferred for the compilers
108 themselves), MIME attachments (preferred for the web pages),
109 or as uuencoded gzipped text.
111 When you have all these pieces, bundle them up in a mail
112 message and send it to gdb-patches@sourceware.cygnus.com. All
113 patches and related discussion should be sent to the
114 gdb-patches mailinglist. For further information on the GDB
115 CVS repository, see the Anonymous read-only CVS access and
116 Read-write CVS access page.
120 Supplemental information for GDB:
122 o Please try to run the relevant testsuite before and after
125 If the contributor doesn't do it then the maintainer will. A
126 contributor might include before/after test results in their
130 o For bug fixes, please try to include a way of
131 demonstrating that the patch actually fixes something.
133 The best way of doing this is to ensure that the
134 testsuite contains one or more test cases that
135 fail without the fix but pass with the fix.
137 People are encouraged to submit patches that extend
141 o Please read your patch before submitting it.
143 A patch containing several unrelated changes or
144 arbitrary reformats will be returned with a request
145 to re-formatting / split it.
148 o If ``gdb/configure.in'' is modified then you don't
149 need to include patches to the regenerated file
152 The maintainer will re-generate those files
153 using autoconf (2.13 as of 2000-02-29).
