* Administrivia
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+generated from the grammars is out of date, and to bootstrap with an
+out-of-date version of the C code, but the process is not foolproof.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
that 1. Bison compiles cleanly, 2. the parsers it produces compile
cleanly too.
+- Build with -DGNULIB_POSIXCHECK. It suggests gnulib modules that can
+ fix portability issues.
+
- run `make maintainer-check' which:
- runs `valgrind -q bison' to run Bison under Valgrind.
- runs the parsers under Valgrind.
that it does not make sense for glr.c, which should be ANSI,
but currently is actually GNU C, nor for lalr1.cc.
+- Test with a very recent version of GCC for both C and C++. Testing
+ with older versions that are still in use is nice too.
+
* Release Procedure
-** Try to get the *.pot files to the Translation Project at least one week
-before a stable release, to give them time to translate them.

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.

+
+** Check copyright years.
+We update years in copyright statements throughout Bison once at the
+start of every year by running `make update-copyright'. However, before
+a release, it's good to verify that it's actually been run. Besides the
+copyright statement for each Bison file, check the copyright statements
+that the skeletons insert into generated parsers, and check all
+occurrences of PACKAGE_COPYRIGHT_YEAR in configure.ac.
** Update NEWS
The version number, *and* the date of the release (including for
** Update ChangeLog
Should have an entry similar to `Version 1.49b.'.
-** 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:
http://www.gnu.org/prep/maintain/maintain.html#Automated-FTP-Uploads
-After following the instructions there to register your information so you're
-permitted to upload, here's a brief reminder of how to roll the tarballs and
-upload them:
+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
*** 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.
+where alpha can be replaced by beta or stable and F125BDF3 should be
+replaced with your key ID.
-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,
-and coordinator@translationproject.org.
+Complete/fix the announcement file. The generated list of recipients
+(info-gnu@gnu.org, bug-bison@gnu.org, help-bison@gnu.org,
+bison-patches@gnu.org, and coordinator@translationproject.org) is
+appropriate for a stable release or a ``serious beta''. For any other
+release, drop at least info-gnu@gnu.org. For an example of how to fill
+out the rest of the template, search the mailing list archives for the
+most recent release announcement.
-Send the same announcement on the comp.compilers newsgroup by sending
-email to compilers@iecc.com. Do not make any Cc as the moderator will
-throw away anything cross-posted or Cc'ed. It really needs to be a
-separate message.
+For a stable release, send the same announcement on the comp.compilers
+newsgroup by sending email to compilers@iecc.com. Do not make any Cc as

** Bump the version number
In configure.ac. Run `make'. So that developers don't accidentally add new
