1 ================================================================
4 * This file attempts to describe the rules to use when hacking
7 * Don't put this file into the distribution. Don't mention it in the
11 ================================================================
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 the
16 appropriate paperwork.
17 Second, be sure to add their name and email address to THANKS
19 * If a change fixes a test, mention the test in the ChangeLog entry.
21 * If somebody reports a new bug, mention his name in the ChangeLog entry
22 and in the test case you write. Put him into THANKS.
24 * The correct response to most actual bugs is to write a new test case
25 which demonstrates the bug. Then fix the bug, re-run the test suite,
26 and check everything in.
28 * Some files in the automake package are not owned by automake. These
29 files should never be edited here. These files are
31 INSTALL (autoconf-patches@gnu.org),
32 config.guess, config.sub (config-patches@gnu.org),
33 texinfo.tex (bug-texinfo@gnu.org),
34 Most of them are updated before release with `make fetch'.
36 * Changes other than bug fixes must be mentioned in NEWS
39 ================================================================
42 * We've adopted the convention that internal AC_SUBSTs should be
43 named with a leading `am__', and internally generated targets should
44 be named with a leading `am--'. This convention is very new
45 (as of Feb 7 2001) and so it isn't yet universally used. But all
46 new code should use it.
48 We used to use `_am_' as the prefix for an internal AC_SUBST.
49 However, it turns out that NEWS-OS 4.2R complains if a Makefile
50 variable begins with `_'. Yay for them. I changed the target
51 naming convention just to be safe.
53 ================================================================
56 * Always use $(...) and not ${...}
58 * Use `:', not `true'. Use `exit 1', not `false'.
60 * Use `##' comments liberally. Comment anything even remotely
63 * Never use basename or dirname. Instead use sed
65 * Do not use `cd' within back-quotes, use `$(am__cd)' instead.
66 Otherwise the directory name may be printed, depending on CDPATH.
68 * For install and uninstall rules, if a loop is required, it should be
69 silent. Then the body of the loop itself should print each
70 "important" command it runs. The printed commands should be preceded
74 ================================================================
75 = Editing automake.in and aclocal.in
77 * Indent using GNU style. For historical reasons, the perl code
78 contains portions indented using Larry Wall's style (perl-mode's
79 default), and other portions using the GNU style (cperl-mode's
80 default). Write new code using GNU style.
82 * Don't use & for function calls, unless required.
83 The use of & prevents prototypes from being checked.
84 Just as above, don't change massively all the code to strip the
85 &, just convert the old code as you work on it, and write new
91 ================================================================
94 * To regenerate dependent files created by aclocal and automake,
95 use the `bootstrap' script. It uses the code from the source
96 tree, so the resulting files (aclocal.m4 and Makefile.in) should
97 be the same as you would get if you install this version of
98 automake and use it to generate those files.
100 * Dependent files aclocal.m4, configure and Makefile.in in all
101 directories should be up to date in the CVS repository, so that
102 the changes in them can be easily noticed and analyzed.
105 ================================================================
108 * Use "make check" and "make maintainer-check" liberally
110 * Make sure each test file is executable
113 ================================================================
116 * Fetch new versions of the files that are maintained by the FSF.
117 Commit. Unfortunately you need an FSF account to do this.
118 (You can also use `make fetch', but that is still woefully incomplete.)
120 * Update NEWS. For an alpha release, update README-alpha.
122 * Update the version number in configure.ac.
123 (The idea is that every other alpha number will be a net release.
124 The repository will always have its own "odd" number so we can easily
125 distinguish net and repo versions.)
129 * Run ./bootstrap, ./configure, make.
131 * Run `make cvs-dist'.
132 This will run distcheck to create the tarball, commit the last
133 NEWS/configure.ac/ChangeLog changes, and tag the repository.
135 * Update version number in configure.ac to next alpha number.
136 Re-run ./bootstrap and commit.
138 * gpg -ba -o automake-VERSION.tar.gz.sig automake-VERSION.tar.gz
139 gpg -ba -o automake-VERSION.tar.bz2.sig automake-VERSION.tar.bz2
140 echo 'directory: automake' >automake-VERSION.tar.gz.directive
141 gpg --clearsign automake-VERSION.tar.gz.directive
142 cp automake-VERSION.tar.{gz,bz2}.directive.asc
144 scp automake-VERSION.tar.{gz,bz2}{,.sig} sources.redhat.com:~ftp/pub/automake
147 ncftpput ftp-upload.gnu.org /incoming/alpha \
148 automake-VERSION.tar.{gz,bz2}{,.directive.asc,.sig}
150 ncftpput ftp-upload.gnu.org /incoming/ftp \
151 automake-VERSION.tar.{gz,bz2}{,.directive.asc,.sig}
153 Send announcement at least to autotools-announce@gnu.org, and
154 automake@gnu.org. If not an alpha, announcement must also go to
