@chapter Releasing @value{GDBN}
@cindex making a new release of gdb
-@section Before the branch
+@section Obsolete any code
-The most important objective at this stage is to find and fix simple
-changes that become a pain to track once the branch is created. For
-instance, configuration problems that stop @value{GDBN} from even
-building. If you can't get the problem fixed, document it in the
-@file{PROBLEMS} file.
+Before anything else, poke the other developers (and around the source
+code) to see there is anything that can be removed from @value{GDBN} (an
+old target, an unused file).
-@subheading Obsolete any code
+Obsolete code is identified by adding an @code{OBSOLETE} prefix to every
+line. Doing this means that it is easy to identify obsolete code when
+grepping through the sources.
-Mark as @kbd{OBSOLETE} any uninteresting targets or code files. This
-has a number of steps and is slow --- mainly to ensure that people have
-had a reasonable chance to respond. Remember, everything on the
-internet takes a week.

@end itemize
-@subheading Refresh any imported files.
+@emph{Maintainer note: Removing old code, while regrettable, is a good
+thing. Firstly it helps the developers by removing code that is either
+no longer relevant or simply wrong. Secondly since it removes any
+history associated with the file (effectively clearing the slate) the
+developer has a much freer hand when it comes to fixing broken files.}
-A number of files are taken from external repositories. They include:
-
-@itemize @bullet

-@file{texinfo/texinfo.tex}

@subheading Organize and announce the schedule.
@end itemize
As an aside, the branch tag name is probably regrettable vis:
-@file{gdb_N_M-YYYY-MM-DD-@{branch,branchpoint@}}.

+@subheading Prompt for @file{gdb/NEWS}
+
+People always forget. Send a post reminding them but also if you know
+something interesting happened add it your self.
+
+@subheading Review @file{gdb/README}
+
+Grab one of the nightly snapshots and then walk through the
+@file{gdb/README} looking for anything that can be improved.
+
+@subheading Check the ARI
+
+ARI is an @code{awk} script (Awk Regression Indicator?) that checks for a
+number of errors and coding conventions. The checks include things like
+using @code{malloc} instead of @code{xmalloc} and file naming problems.
+There shouldn't be any regressions.
+
+@section Cut the branch
+
+@subheading The dirty work
+
+I think something like the below was used:
+
+@example
+$ d=`date -u +%Y-%m-%d`
+$ echo $d
+2002-01-24
+$ cvs -f -d /cvs/src rtag -D $d-gmt \
+gdb_5_1-$d-branchpoint insight+dejagnu
+$ cvs -f -d /cvs/src rtag -b -r gdb_V_V-$d-branchpoint \
+gdb_5_1-$d-branch insight+dejagnu
+$
+@end example
+
+@itemize @bullet
+@item
+the @kbd{-D YYYY-MM-DD-gmt} forces the branch to an exact date/time.
+@item
+the trunk is first taged so that the branch point can easily be found
+@item
+Insight (which includes GDB) and dejagnu are tagged at the same time
+@end itemize
+
+@subheading Post the branch info
+
+@subheading Update the web and news pages
+
+@subheading Tweak cron to track the new branch
+
+@section Stabilize the branch
+
+Something goes here.
+
+@section Create a Release
+
+This procedure can be followed when creating beta and final final
+releases. With a beta many of the steps can be skipped.
@subheading Establish a few defaults.
@example
-$ b=gdb_5_1_0_1-2002-01-03-branch
-$ v=5.1.0.1
-$ cd /sourceware/snapshot-tmp/gdbadmin-tmp/$b
+$ b=gdb_5_1-2001-07-29-branch
+$ v=5.1.1
+$ t=/sourceware/snapshot-tmp/gdbadmin-tmp
+$ echo $t/$b/$v
+$ mkdir -p $t/$b/$v
+$ cd $t/$b/$v
+$ pwd
+/sourceware/snapshot-tmp/gdbadmin-tmp/gdb_5_1-2001-07-29-branch/5.1.1
$ which autoconf
/home/gdbadmin/bin/autoconf
+$
@end example
-NB: Check the autoconf version carefully. You want to be using
-@file{gdbadmin}'s version (which is really the version taken from the
-binutils snapshot). SWARE may have a different version installed.
+NB: Check the autoconf version carefully. You want to be using the
+version taken from the binutils snapshot directory. It is most likely
+that your system's installed version (@file{/usr/bin}?) is probably
+correct.
@subheading Check out the relevant modules:
@example
-$ for m in gdb insight dejagnu; do
+$ for m in gdb insight dejagnu
+do
( mkdir -p $m && cd $m && cvs -q -f -d /cvs/src co -P -r $b $m )
done
+$
@end example
NB: The reading of @file{.cvsrc} is disabled (@file{-f}) so that there
-isn't any confusion between what is written here and what CVS really
-does.
+isn't any confusion between what is written here and what your local CVS
+really does.
+
+@subheading Update relevant files.
-@subheading Update the file @file{gdb/version.in} where applicable.
+@subsubheading @file{gdb/NEWS}
+
+Major releases get their comments added as part of the mainline. Minor
+releases should probably mention any significant bugs that were fixed.
+
+Don't forget to update the ChangeLog.
@example
-$ for m in gdb insight; do echo $v > $m/src/gdb/version.in ; done
+$ emacs gdb/src/gdb/NEWS
+...
+c-x 4 a
+...
+c-x c-s c-x c-c
+$ cp gdb/src/gdb/NEWS insight/src/gdb/NEWS
+$ cp gdb/src/gdb/ChangeLog insight/src/gdb/ChangeLog
@end example
+@subsubheading @file{gdb/README}
-@subheading Mutter something about creating a @file{ChangeLog} entry. (both trunk and branch).
+You'll need to update: the version, the update date, and who did it.
@example
-$ emacs gdb/src/gdb/version.in
+$ emacs gdb/src/gdb/README
+...
c-x 4 a
-Bump version to 5.1.0.1.
+...
c-x c-s c-x c-c
+$ cp gdb/src/gdb/README insight/src/gdb/README
+$ cp gdb/src/gdb/ChangeLog insight/src/gdb/ChangeLog
@end example
-ditto for @file{insight/src/gdb/version.in}
+@emph{Maintainer note: Hopefully the README file was reviewed before the
+initial branch was cut so just a simple substitute is needed to get it
+updated.}
-@subheading Mutter something about updating @file{README}
+@emph{Maintainer note: Other projects generate @file{README} and
+@file{INSTALL} from the core documentation. This might be worth
+pursuing.}
-For dejagnu, edit @file{dejagnu/src/dejagnu/configure.in} and set it to
-gdb-$v and then regenerate configure. Mention this in the dejagnu
-@file{ChangeLog}.
+@subsubheading @file{gdb/version.in}
@example
-$ emacs dejagnu/src/dejagnu/configure.in
+$ echo $v > gdb/src/gdb/version.in
+$ emacs gdb/src/gdb/version.in
...
c-x 4 a
-Bump version to 5.1.0.1.
-* configure: Re-generate.
+...
c-x c-s c-x c-c
-$ ( cd dejagnu/src/dejagnu && autoconf )
+$ cp gdb/src/gdb/version.in insight/src/gdb/version.in
+$ cp gdb/src/gdb/ChangeLog insight/src/gdb/ChangeLog
@end example
-@subheading Build the snapshot:
+@subsubheading @file{dejagnu/src/dejagnu/configure.in}
+
+Dejagnu is more complicated. The version number is a parameter to
+@var{AM_INIT_AUTOMAKE}. Tweak it to read something like
+@var{gdb-5.1.1}.
+
+Re-generate configure.
+
+Add a ChangeLog.
+
+@subheading Do the dirty work
+
+This is identical to the process used when creating the daily snapshot.
@example
-$ for m in gdb insight dejagnu; do
+$ for m in gdb insight dejagnu
+do
( cd $m/src && gmake -f Makefile.in $m.tar.bz2 )
done
@end example
-@subheading Do another @kbd{CVS update} to see what the damage is.
+@subheading Check the source files
+
+You're looking for files that have mysteriously disappeared as the
+@kbd{distclean} has the habit of deleting files it shouldn't. Watch out
+for the @file{version.in} update @kbd{cronjob}.
@example
-$ ( cd gdb/src && cvs -q update )
+$ ( cd gdb/src && cvs -f -q -n update )
+M djunpack.bat
+? proto-toplev
+? gdb-5.1.1.tar.bz2
+M gdb/ChangeLog
+M gdb/NEWS
+M gdb/README
+M gdb/version.in
+? gdb/p-exp.tab.c
+? gdb/doc/gdb.info-11
+? gdb/doc/gdb.info-12
+? gdb/doc/gdb.info-13
+? gdb/doc/gdb.info-14
+? gdb/doc/gdb.info-15
+? gdb/doc/gdbint.info-4
+? gdb/doc/gdbint.info-5
+$
@end example
-You're looking for files that have mysteriously disappeared as the
-@kbd{distclean} has the habit of deleting files it shouldn't. Watch out
-for the @file{version.in} update cronjob.
+@emph{Don't worry about the @file{gdb.info-??} or
+@file{gdb/p-exp.tab.c}. They were generated (and yes @file{gdb.info-1}
+was also generated only something strange with CVS means that they
+didn't get supressed). Fixing it would be nice though.}
-@subheading Copy all the @file{.bz2} files to the ftp directory:
+@subheading Re-pack the release with @code{gzip}
@example
-cp */src/*.bz2 ~ftp/.....
+$ cp */*/*.bz2 .
+$ bunzip2 -k -v *.bz2
+$ gzip -9 -v *.tar
@end example
-@subheading Something about @kbd{gzip}'ing them.
+NB: A pipe such as @kbd{bunzip2 < xxx.bz2 | gzip -9 > xxx.gz} shouldn't
+be used since, in that mode, gzip doesn't know the file name information
+and consequently can't include it. This is also why the release process
+runs @code{tar} and @code{bzip2} as separate passes.
-@subheading Something about web pages?
+@emph{Maintainer note: The release process could be changed to create
+@file{.tar} rather than @file{.tar.bz2} files.}
-@subheading Something about documentation?
+@section Check the release
-@subheading Cleanup the release tree
+Grab the @file{gdb.tar.bz2}, copy it to your local machine and then try
+a simple build using it.
-In particular you'll need to:
+If this is a pre-release just copy the @file{.bz2} files to the snapshot
+directory and skip the remaining steps.
+
+If it is a final release, also make it available under a bogus name so
+that others can download and check it.
+
+@emph{Maintainer note: This adds an extra day to the release process but
+is very much worth it. Other developers are given the oportunity to
+check that things like your @file{NEWS} entries are correct or that
+other changes actually work.}
+
+@section Release the tar ball
+
+This is where, unfortunatly, the notes just get vague.
+
+@subheading Install on sware
+
+@example
+$ cp *.bz2 *.gz ~ftp/pub/gdb/releases
+@end example
+
+@subheading Create and update the web pages.
+
+Try the following:
@itemize @bullet
@item
-Commit the changes to @file{ChangeLog} and @file{version.in}
+create the directory @file{htdocs/@var{version}} (e.g., @file{htdocs/5.1.1}
+@item
+copy @file{index.html} and @file{ANNOUNCE} from the previous release
+into the @file{htdocs/@var{version}} directory and edit for content.
+Things like the MD5 sums, @kbd{ls -l} output, the version number and so
+on will need updating. Add NEWS entries to the @file{ANNOUNCE}. This
+ensures that the previous announcement is kept somewhere handy.
+@item
+copy the @file{NEWS} from the distro into the
+@file{htdocs/@var{version}} directory, trim down to just the most recent
+news items
@item
-Tag the repository.
+Add a short (identical) announcement to both @file{htdocs/index.html}
+and @file{htdocs/news/index.html}
+@item
+edit the script @file{htdocs/index.sh} to link in the new release
+number. Run it across all @file{index.html} files vis @kbd{./index.sh
+index.html */index.html}.
+@item
+grep the @file{htdocs} tree for references to the previous release
+version (@file{htdocs/download/index.html})
@end itemize
+@emph{Maintainer note: This step is too fragile --- it is too easy to
+mis one of the entries and forget to update it.}
+
+@subheading Generate online docs
+
+You need to find the magic command that is used to generate the online
+docs from the @file{.tar.bz2}. The best way is to look in the output
+from one of the nightly cronjobs and then just edit accordingly.
+Something like:
+
+@example
+$ ~/ss/update-web-docs \
+ ~ftp/pub/gdb/releases/gdb-5.1.1.tar.bz2 \
+ $PWD/www \
+ /www/sourceware/htdocs/gdb/5.1.1/onlinedocs \
+ gdb
+@end example
+
+@subheading Something about @file{ANNOUNCEMENT}
+
+Send the @file{ANNOUNCEMENT} file you created above to:
+
+@itemize @bullet
+@item
+@email{gdb-announce@@sources.redhat.com, GDB Announcement mailing list}
+@item
+The gnu announce list (but delay it a day or so to let things get out).
+@end itemize
+
+@subheading Install it on GNU
+
+At the time of writing, the GNU machine was @kbd{gnudist.gnu.org} in
+@file{~ftp/gnu/gdb} (I think, I'm still waiting for it to copy into my
+home directory).
+
+@section Cleanup
+
+@subheading Commit outstanding changes
+
+In particular you'll need to commit the changes to:
+
+@itemize @bullet
+@item
+@file{gdb/ChangeLog}
+@item
+@file{gdb/version.in}
+@item
+@file{gdb/NEWS}
+@item
+@file{gdb/README}
+@end itemize
+
+@subheading Tag the release
+
+Something like:
+
+@example
+$ d=`date -u +%Y-%m-%d`
+$ echo $d
+2002-01-24
+$ ( cd insight/src/gdb && cvs -f -q update )
+$ ( cd insight/src && cvs -f -q tag gdb_5_1_1-$d-release )
+@end example
+
+Insight is used since that contains more of the release than GDB (yes
+dejagnu doesn't get tagged but I think we can live with that.).
+
+@subheading Restart @file{gdb/version.in}
+
+If @file{gdb/version.in} does not contain an ISO date such as
+@kbd{2002-01-24} then the daily @code{cronjob} won't update it. Having
+committed all the release changes it can be set to
+@file{5.1.0_0000-00-00-cvs} which will restart things (yes the @kbd{_}
+is important - it affects the snapshot process).
+
+Don't forget the @file{ChangeLog}.
+
+@subheading Merge into trunk
-@section After the release
+The files committed to the branch may also need changes merged into the
+trunk.
-Remove any @kbd{OBSOLETE} code.
+@section Post release
+Remove any @code{OBSOLETE} code.
