3 This file attempts to describe the rules to use when hacking Bison.
4 Don't put this file into the distribution. Don't mention it in the
7 Everything related to the development of Bison is on Savannah:

14 ** If you incorporate a change from somebody on the net:
15 First, if it is a large change, you must make sure they have signed
16 the appropriate paperwork. Second, be sure to add their name and
17 email address to THANKS.
19 ** If a change fixes a test, mention the test in the ChangeLog entry.
22 If somebody reports a new bug, mention his name in the ChangeLog entry
23 and in the test case you write. Put him into THANKS.
25 The correct response to most actual bugs is to write a new test case
26 which demonstrates the bug. Then fix the bug, re-run the test suite,
27 and check everything in.
33 Which include serious bug fixes, must be mentioned in NEWS.
36 Only user visible strings are to be translated: error messages, bits
37 of the .output file etc. This excludes impossible error messages
38 (comparable to assert/abort), and all the --trace output which is
39 meant for the maintainers only.
48 Try to run the test suite with more severe conditions before a
51 - Configure the package with --enable-gcc-warnings, so that one checks
52 that 1. Bison compiles cleanly, 2. the parsers it produces compile
55 - run `make maintainer-check' which:
56 - runs `valgrind -q bison' to run Bison under Valgrind.
57 - runs the parsers under Valgrind.
58 - runs the test suite with G++ as C compiler...
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.
69 ** Try to get the *.pot files to the Translation Project at least one week
70 before a stable release, to give them time to translate them.
75 ** Update the foreign files
76 Running `./bootstrap' in the top level should update them all for you.
77 This covers PO files too. Sometimes a PO file contains problems that
78 causes it to be rejected by recent Gettext releases; please report
79 these to the Translation Project.
82 The version number, *and* the date of the release (including for
86 Should have an entry similar to `Version 1.49b.'.
87 Check all this in once `make distcheck' passes.
90 Running `make alpha' is absolutely perfect for beta releases: it makes
91 the tarballs, the xdeltas, and prepares (in /tmp/) a proto
92 announcement. It is so neat, that that's what I use anyway for
93 genuine releases, but adjusting things by hand (e.g., the urls in the
94 announcement file, the ChangeLog which is not needed etc.).
96 If it fails, you're on your own...
101 Put the tarballs/xdeltas where they should be. Or put it somewhere,
102 and send the URL to ftp-upload@gnu.org.
104 ** Bump the version number
105 In configure.ac. Run `make', check this in.
108 Complete/fix the announcement file, and send it at least to
109 info-gnu@gnu.org (if a real release, or a ``serious beta''),
110 bug-bison@gnu.org, help-bison@gnu.org, bison-patches@gnu.org,
111 and translation@iro.umontreal.ca.
113 Send the same announcement on the comp.compilers newsgroup by sending
114 email to compilers@iecc.com. Do not make any Cc as the moderator will
115 throw away anything cross-posted or Cc'ed. It really needs to be a
