Bison is written using Bison grammars, so there are bootstrapping
issues. The bootstrap script attempts to discover when the C code
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.,
+Bison repository requests) differ. To upgrade the submodules (i.e.,
to check out the version that is actually requested by the subscriber,
run "git submodule update".

-The autoconf files we use are currently:
+The Autoconf files we use are currently:
m4/m4.m4
lib/m4sugar/m4sugar.m4
** make check
Use liberally.
+** make maintainer-check-valgrind
+This target uses valgrind both to check bison, and the generated parsers.
+
+This is not mature on Mac OS X. First, Valgrind does support the way bison
+calls m4, so Valgrind cannot be used to check bison on Mac OS X.
+
+Second, there are many errors that come from the platform itself, not from
+bison. build-aux/darwin11.4.0.valgrind addresses some of them.
+
+Third, valgrind issues warnings such as:
+
+ --99312:0:syswrap- WARNING: Ignoring sigreturn( ..., UC_RESET_ALT_STACK );
+
+which cause the test to fail uselessly. It is hard to ignore these errors
+with a major overhaul of the way instrumentation is performed in the test
+suite. So currently, do not try to run valgrind on Mac OS X.
+
** Release checks
Try to run the test suite with more severe conditions before a
release:
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
-betas).
+** Update NEWS, commit and tag.
+See do-release-commit-and-tag in README-release. For a while, we used
+beta names such as "2.6_rc1". Now that we use gnulib in the release
+procedure, we must use "2.5.90", which has the additional benefit of
+being properly sorted in "git tag -l".
-** Mention the release name in a commit message
-Should have an entry similar to "Version 2.3b.".
-
-** 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 -m "Bison 2.3b."
-
-** Push
-Once "make distcheck" passes, push your changes and the tag.
-"git push" without arguments will not push the tag.
-
-** make alpha, beta, or release
+** make alpha, beta, or stable
See README-release.
** Upload
*** Using gnupload
You need "ncftp".
-At the end "make release" (or alpha/beta) will display the prodecure
-to run. Just copy and paste it in your shell.
+At the end "make stable" (or alpha/beta) will display the procedure to
+run. Just copy and paste it in your shell.
*** By hand
issue.
** Announce
-To generate a template announcement file:
+The "make stable" (or alpha/beta) command just created a template,
+$HOME/announce-bison-X.Y. Otherwise, to generate it, run:
make RELEASE_TYPE=alpha gpg_key_ID=F125BDF3 announcement
the moderator will 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:
+** Prepare NEWS
+So that developers don't accidentally add new items to the old NEWS
+entry, create a new empty entry in line 3 (without the two leading
+spaces):
- Changes in version ?.? (????-??-??):
+ * Noteworthy changes in release ?.? (????-??-??) [?]
Push these changes.
