Everything related to the development of Bison is on Savannah:

* Administrivia
which demonstrates the bug. Then fix the bug, re-run the test suite,
and check everything in.
+** You may find it useful to install the git-merge-changelog merge driver:
+
+ http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/git-merge-changelog.c
+
+When following the generic installation instructions there, keep in mind that
+your clone of Bison's git repository already contains appropriate
+.gitattributes files, and running Bison's bootstrap script will make the
+necessary changes to .git/config.
+
* Hacking
meant for the maintainers only.
+* Working from the repository
+
+These notes intend to help people working on the checked-out sources.
+These requirements do not apply when building from a distribution tarball.
+
+** Requirements
+
+We've opted to keep only the highest-level sources in the repository.
+This eases our maintenance burden, (fewer merges etc.), but imposes more
+requirements on anyone wishing to build from the just-checked-out sources.
+For example, you have to use the latest stable versions of the maintainer
+tools we depend upon, including:
+
+- Automake <http://www.gnu.org/software/automake/>
+- Autoconf <http://www.gnu.org/software/autoconf/>
+- Flex <http://www.gnu.org/software/flex/>
+- Gettext <http://www.gnu.org/software/gettext/>
+- Gzip <http://www.gnu.org/software/gzip/>
+- Perl <http://www.cpan.org/>
+- Rsync <http://samba.anu.edu.au/rsync/>
+- Tar <http://www.gnu.org/software/tar/>
+
+Valgrind <http://valgrind.org/> is also highly recommended, if
+Valgrind supports your architecture.
+
+Bison is written using Bison grammars, so there are bootstrapping
+issues. The bootstrap script attempts to discover when the C code
+generated from the grammars is out of date, and to bootstrap with an
+out-of-date version of the C code, but the process is not foolproof.
+Also, you may run into similar problems yourself if you modify Bison.
+
+Only building the initial full source tree will be a bit painful.
+Later, after synchronizing from the repository a plain `make' should
+be sufficient.
+
+** First checkout
+
+Obviously, if you are reading these notes, you did manage to check out
+this package from the repository. For the record, you will find all the
+relevant information on:
+
+ http://savannah.gnu.org/git/?group=bison
+
+Bison uses Git submodules: subscriptions to other Git repositories.
+In particular it uses gnulib, the GNU portability library. To ask Git
+to perform the first checkout of the submodules, run
+
+ $ git submodule update --init
+
+Git submodule support is weak before versions 1.6 and later, you
+should probably upgrade Git if your version is older.
+
+The next step is to get other files needed to build, which are
+extracted from other source packages:
+
+ $ ./bootstrap
+
+And there you are! Just
+
+ $ ./configure
+ $ make
+ $ make check
+
+At this point, there should be no difference between your local copy,
+and the master copy:
+
+ $ git diff
+
+should output no difference.
+
+Enjoy!
+
+** Updating
+
+The use of submodules make things somewhat different because git does
+not support recursive operations: submodules must be taken care of
+explicitly by the user.
+
+*** Updating Bison
+
+If you pull a newer version of a branch, say via `git pull', you might
+import requests for updated submodules. A simple `git diff' will
+reveal if the current version of the submodule (i.e., the actual
+contents of the gnulib directory) and the current request from the
+subscriber (i.e., the reference of the version of gnulib that the
+Bison reporitory requests) differ. To upgrade the submodules (i.e.,
+to check out the version that is actually requested by the subscriber,
+run `git submodule update'.
+
+ $ git pull
+ $ git submodule update
+
+*** Updating a submodule
+To update a submodule, say gnulib, do as follows:
+
+Get the most recent version of the master branch from git.
+
+ $ cd gnulib
+ $ git fetch
+ $ git checkout -b master --track origin/master
+
+Make sure Bison can live with that version of gnulib.
+
+ $ cd ..
+ $ ./bootstrap
+ $ make distcheck
+
+Register your changes.
+
+ $ git checkin ...
+
+
* Test suite
** make check
- Change tests/atlocal/CFLAGS to add your preferred options. For
instance, `-traditional' to check that the parsers are K&R. Note
that it does not make sense for glr.c, which should be ANSI,
- but currently is actually GNU C, nor for lalr1.cc, which anyway is
- not exercised yet in the test suite.
+ but currently is actually GNU C, nor for lalr1.cc.
* Release Procedure
causes it to be rejected by recent Gettext releases; please report
these to the Translation Project.
+** Update README
+Make sure the information in this file is current. Most notably, make sure it
+recommends a version of GNU M4 that is compatible with the latest Bison
+sources.
+
** Update NEWS
The version number, *and* the date of the release (including for
betas).
** Update ChangeLog
Should have an entry similar to `Version 1.49b.'.
-Check all this in once `make distcheck' passes.
+
+** Update configure.ac
+Be sure PACKAGE_COPYRIGHT_YEAR is up-to-date.
+
+** Tag the release
+Before Bison will build with the right version number, you must tag the release
+in git. Do this after all other changes. The command is similar to:
+
+ git tag -a v2.3b
+
+The log message can be simply:
+
+ Bison 2.3b
+
+** make distcheck
+Be sure to use automake 1.10.3, 1.11.1, or later in order to avoid the
+security issue described here:
+
+ http://thread.gmane.org/gmane.comp.sysutils.autotools.announce/131
+
+** Push
+Once `make distcheck' passes, push your changes and the tag.
+`git push' without arguments will not push the tag.
** make alpha
+FIXME: `make alpha' is not maintained and is broken. These
+instructions need to be replaced or removed.
+
Running `make alpha' is absolutely perfect for beta releases: it makes
the tarballs, the xdeltas, and prepares (in /tmp/) a proto
announcement. It is so neat, that that's what I use anyway for
genuine releases, but adjusting things by hand (e.g., the urls in the
announcement file, the ChangeLog which is not needed etc.).
-FIXME: `make alpha' is not maintained and is broken. These
-instructions need to be replaced or removed.
If it fails, you're on your own...
It requires GNU Make.
** Upload
-Put the tarballs/xdeltas where they should be. Or put it somewhere,
-and send the URL to ftp-upload@gnu.org.
+The generic GNU upload procedure is at:
-** Bump the version number
-In configure.ac. Run `make', check this in.
+ http://www.gnu.org/prep/maintain/maintain.html#Automated-FTP-Uploads
+
+Follow the instructions there to register your information so you're permitted
+to upload. Make sure your public key has been uploaded at least to
+keys.gnupg.net. You can upload it with:
+
+ gpg --keyserver keys.gnupg.net --send-keys F125BDF3
+
+where F125BDF3 should be replaced with your key ID.
+
+Here's a brief reminder of how to roll the tarballs and upload them:
+
+*** make distcheck
+*** gpg -b bison-2.3b.tar.gz
+*** In a file named `bison-2.3b.tar.gz.directive', type:
+
+ version: 1.1
+ directory: bison
+ filename: bison-2.3b.tar.gz
+
+*** gpg --clearsign bison-2.3b.tar.gz.directive
+*** ftp ftp-upload.gnu.org # Log in as anonymous.
+*** cd /incoming/alpha # cd /incoming/ftp for full release.
+*** put bison-2.3b.tar.gz # This can take a while.
+*** put bison-2.3b.tar.gz.sig
+*** put bison-2.3b.tar.gz.directive.asc
+*** Repeat all these steps for bison-2.3b.tar.bz2.
+
+** Update Bison manual on www.gnu.org.
+
+*** You need a non-anonymous checkout of the web pages directory.
+
+ $ cvs -d YOUR_USERID@cvs.savannah.gnu.org:/web/bison checkout bison
+
+*** Get familiar with the instructions for web page maintainers.
+http://www.gnu.org/server/standards/readme_index.html
+http://www.gnu.org/server/standards/README.software.html
+especially the note about symlinks.
+
+*** Build the web pages.
+Assuming BISON_CHECKOUT refers to a checkout of the Bison dir, and
+BISON_WWW_CHECKOUT refers to the web directory created above, do:
+
+ $ cd $BISON_CHECKOUT/doc
+ $ make stamp-vti
+ $ ../build-aux/gendocs.sh -o "$BISON_WWW_CHECKOUT/manual" \
+ bison "Bison - GNU parser generator"
+ $ cd $BISON_WWW_CHECKOUT
+
+Verify that the result looks sane.
+
+*** Commit the modified and the new files.
+
+*** Remove old files.
+Find the files which have not been overwritten (because they belonged to
+sections that have been removed or renamed):
+
+ $ cd manual/html_node
+ $ ls -lt
+
+Remove these files and commit their removal to CVS. For each of these
+files, add a line to the file .symlinks. This will ensure that
+hyperlinks to the removed files will redirect to the entire manual; this
+is better than a 404 error.
+
+There is a problem with 'index.html' being written twice (once for POSIX
+function 'index', once for the table of contents); you can ignore this
+issue.
** Announce
+To generate a template announcement file:
+
+ make RELEASE_TYPE=alpha gpg_key_ID=F125BDF3 announcement
+
+where alpha can be replaced by beta or major and F125BDF3 should be replaced
+with your key ID. For an example of how to fill out the template, search the
+mailing list archives for the most recent release announcement.
+
Complete/fix the announcement file, and send it at least to
info-gnu@gnu.org (if a real release, or a ``serious beta''),
bug-bison@gnu.org, help-bison@gnu.org, bison-patches@gnu.org,
throw away anything cross-posted or Cc'ed. It really needs to be a
separate message.
+** Bump the version number
+In configure.ac. Run `make'. So that developers don't accidentally add new
+items to the old NEWS entry, create a new empty NEWS entry something like:
+
+ Changes in version ?.? (????-??-??):
+
+Push these changes.
