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 Submissions which do not conform to the standards will be
33 returned with a request to reformat the changes.

37 GDB has certain additional coding requirements. Those
38 requirements are explained in the GDB internals documentation.

43 o Copyright Assignment
45 Before we can accept code contributions from you, we need a
46 copyright assignment form filled out and filed with the FSF.
48 See some documentation by the FSF for details and contact us
49 (either via the GDB mailing list or the GDB maintainer that is
50 taking care of your contributions) to obtain the relevant
53 Small changes can be accepted without a copyright assignment form

61 Every patch must have several pieces of information before we
62 can properly evaluate it.
64 A description of the bug and how your patch fixes this
65 bug. A reference to a testsuite failure is very helpful. For
66 new features a description of the feature and your
69 A ChangeLog entry as plaintext (separate from the patch); see
70 the various ChangeLog files for format and content. Note that,
71 unlike some other projects, we do require ChangeLogs also for
72 documentation (i.e., .texi files).
74 The patch itself. If you are accessing the git repository, use
75 "git diff", remembering first to update to the current master;
76 else, use "diff -up OLD NEW". If your version of diff does not
77 support these options, then get the latest version of GNU diff.
79 We accept patches as plain text (preferred for the compilers
80 themselves), MIME attachments (preferred for the web pages),
81 or as uuencoded gzipped text.
83 When you have all these pieces, bundle them up in a mail
84 message and send it to gdb-patches@sourceware.org. All
85 patches and related discussion should be sent to the
86 gdb-patches mailinglist. For further information on the GDB
87 git repository, see the Anonymous read-only git access and
88 Read-write git access page.
92 Supplemental information for GDB:
94 o Please try to run the relevant testsuite before and after
97 If the contributor doesn't do it then the maintainer will. A
98 contributor might include before/after test results in their
102 o For bug fixes, please try to include a way of
103 demonstrating that the patch actually fixes something.
105 The best way of doing this is to ensure that the
106 testsuite contains one or more test cases that
107 fail without the fix but pass with the fix.
109 People are encouraged to submit patches that extend
113 o Please read your patch before submitting it.
115 A patch containing several unrelated changes or
116 arbitrary reformats will be returned with a request
117 to re-formatting / split it.
120 o If ``gdb/configure.ac'' is modified then you don't
121 need to include patches to the regenerated file
124 The maintainer will re-generate those files
125 using autoconf (2.64 as of 2009-08-22).
128 o If ``gdb/gdbarch.sh'' is modified, you don't
129 need to include patches to the generated files
130 ``gdbarch.h'' and ``gdbarch.c''.
132 See ``gdb/configure.ac'' above.
135 o When submitting a patch that fixes a bug
136 in GDB's bug database a brief reference
137 to the bug can be included in the ChangeLog
140 * CONTRIBUTE: Mention PR convention.
143 The text ``PR gdb/4705'' should also be included
144 in the git commit message. That causes the
145 patch to automatically be archived with the PR.
