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.
67 More generally, do not ever use plain `cd' together with a relative
68 directory that does not start with a dot, or you might end up in one
71 * For install and uninstall rules, if a loop is required, it should be
72 silent. Then the body of the loop itself should print each
73 "important" command it runs. The printed commands should be preceded
77 ================================================================
78 = Editing automake.in and aclocal.in
80 * Indent using GNU style. For historical reasons, the perl code
81 contains portions indented using Larry Wall's style (perl-mode's
82 default), and other portions using the GNU style (cperl-mode's
83 default). Write new code using GNU style.
85 * Don't use & for function calls, unless required.
86 The use of & prevents prototypes from being checked.
87 Just as above, don't change massively all the code to strip the
88 &, just convert the old code as you work on it, and write new
94 ================================================================
95 = Working with git/CVS
97 * To regenerate dependent files created by aclocal and automake,
98 use the `bootstrap' script. It uses the code from the source
99 tree, so the resulting files (aclocal.m4 and Makefile.in) should
100 be the same as you would get if you install this version of
101 automake and use it to generate those files.
103 * Dependent files aclocal.m4, configure and Makefile.in in all
104 directories should be up to date in the git repository, so that
105 the changes in them can be easily noticed and analyzed.
107 * Avoid merge commits on the master branch of the public git repository.
108 For unpublished changes in your development tree, it's easiest to
109 rebase against the current master before applying them, this preserves
112 * For changes to appear in more than one branch, apply them to the
113 master branch and then cherry-pick them to the stable branch from
114 master if possible. This keeps the master uncluttered and preserves
115 meta-data on the stable branches.
118 ================================================================
121 * Use "make check" and "make maintainer-check" liberally
123 * Make sure each test file is executable
125 * Use `keep_testdirs=yes' to keep test directories for successful
128 ================================================================
131 * Fetch new versions of the files that are maintained by the FSF.
132 Commit. Unfortunately you need an FSF account to do this.
133 (You can also use `make fetch', but that is still woefully incomplete.)
135 * Update NEWS. For an alpha release, update README-alpha.
137 * Update the version number in configure.ac.
138 (The idea is that every other alpha number will be a net release.
139 The repository will always have its own "odd" number so we can easily
140 distinguish net and repo versions.)
144 * Run ./bootstrap, ./configure, make.
146 * Run `make release-stats' if release statistics in doc/automake.texi
147 have not been updated yet.
149 * Run `make git-release'.
150 This will run distcheck to create the tarballs, commit the last
151 NEWS/configure.ac/ChangeLog changes, tag the repository, sign
152 the tarballs, and upload them.
153 Use `make GNUPLOADFLAGS="--user key" git-release' to sign with
156 * Update version number in configure.ac to next alpha number.
157 Re-run ./bootstrap and commit.
159 * Don't forget to `git push' your changes so they appear in the public
162 * Update the web pages at sources.redhat.com:
163 - bump version in index.rst,
164 - add entry to news.rst,
165 - run `make' to update .html files,
169 make html MAKEINFOFLAGS=--no-split
170 - copy automake.html and automake.pdf to web cvs,
171 - add ChangeLog entry and commit.
173 * Update the manuals at www.gnu.org:
176 wget "http://savannah.gnu.org/cgi-bin/viewcvs/~checkout~/texinfo/texinfo/util/gendocs.sh"
177 wget "http://savannah.gnu.org/cgi-bin/viewcvs/~checkout~/texinfo/texinfo/util/gendocs_template"
178 sh ./gendocs.sh automake "GNU Automake"
179 - copy manuals recursively to web cvs,
181 - Check for link errors, fix them, recheck until convergence:
182 <http://validator.w3.org/checklink>
184 * Send announcement at least to autotools-announce@gnu.org, and
185 automake@gnu.org. If not an alpha, announcement must also go to
186 info-gnu@gnu.org. Copy this announcement into the NEWS feed at
187 <https://savannah.gnu.org/projects/automake>.
