3This file attempts to describe the rules to use when hacking Bison.
4Don't put this file into the distribution. Don't mention it in the
5ChangeLog.

7Everything related to the development of Bison is on Savannah:

12* Administrivia
13
14** If you incorporate a change from somebody on the net:
15First, if it is a large change, you must make sure they have signed
16the appropriate paperwork. Second, be sure to add their name and
17email address to THANKS.
18
19** If a change fixes a test, mention the test in the ChangeLog entry.
20
21** Bug reports
22If somebody reports a new bug, mention his name in the ChangeLog entry
23and in the test case you write. Put him into THANKS.
24
25The correct response to most actual bugs is to write a new test case
26which demonstrates the bug. Then fix the bug, re-run the test suite,
27and check everything in.

30* Hacking
31
32** Visible changes
33Which include serious bug fixes, must be mentioned in NEWS.
34
35** Translations
36Only user visible strings are to be translated: error messages, bits
37of the .output file etc. This excludes impossible error messages
38(comparable to assert/abort), and all the --trace output which is
39meant for the maintainers only.
40
41
42* Test suite
43
44** make check
45Use liberally.
46
47** Release checks
48Try to run the test suite with more severe conditions before a
49release:
50
51- Configure the package with --enable-gcc-warnings, so that one checks
52 that 1. Bison compiles cleanly, 2. the parsers it produces compile
53 cleanly too.
54
55- run `make maintainer-check' which:
56 - runs `valgrind -q bison' to run Bison under Valgrind.
57 - runs the parsers under Valdrind.
58 - runs the test suite with G++ as C compiler...
59
60- Change tests/atlocal/CFLAGS to add your preferred options. For
61 instance, `-traditional' to check that the parsers are K&R. Note
62 that it does not make sense for glr.c, which should be ANSI,
63 but currently is actually GNU C, nor for lalr1.cc, which anyway is
64 not exercised yet in the test suite.
65
66
67* Release Procedure
68
69** Tests
70See above.
71
72** Update the foreign files
73Running `make update' in the top level should make it all for you.
74This covers PO files too. Beware that it happens that some PO files
75contain serious problems and are rejected by recent Gettext releases:
76fix them all, and complain to the Translation Project!
77
78Note that there might be *new* PO files. Don't forget to update the
79whole machinery, which not only includes LINGUAS, but `cvs add'ing the
80PO files too.
81
82** Update NEWS
83The version number, *and* the date of the release (including for
84betas).
85
86** Update ChangeLog
87Should have an entry similar to `Version 1.49b.'.
88Check all this in once `make distcheck' passes.
89
90** make alpha
91Running `make alpha' is absolutely perfect for beta releases: it makes
92the tarballs, the xdeltas, and prepares (in /tmp/) a proto
93announcement. It is so neat, that that's what I use anyway for
94genuine releases, but adjusting things by hand (e.g., the urls in the
95announcement file, the ChangeLog which is not needed etc.).
96
97If it fails, you're on your own...
98
99It requires GNU Make.
100
101** Upload
102Put the tarballs/xdeltas where they should be. Or put it somewhere,
103and send the URL to ftp-upload@gnu.org.
104
105** Bump the version number
106In configure.ac. Run `make', check this in.
107
108** Announce
109Complete/fix the announcement file, and send it at least to
110info@gnu.org (if a real release, or a ``serious beta''),
111bison@gnu.org, and translation@iro.umontreal.ca.
