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.

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.}

@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

|
||||
/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:

@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

|

@subheading Update relevant files.
|
||||
|

@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
|

@end example
|

|

|

@subheading Mutter something about creating a @file{ChangeLog} entry. (both trunk and branch).
|
||||
|
||||
@example
|
||||
$ emacs gdb/src/gdb/version.in
|
||||
c-x 4 a

Bump version to 5.1.0.1.

@end example
|

|
||||
ditto for @file{insight/src/gdb/version.in}
|
||||
|
||||
@subheading Mutter something about updating @file{README}
|
||||
|
||||
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}.
|
||||
|
||||
@example
|
||||
$ emacs dejagnu/src/dejagnu/configure.in
|
||||
$ emacs gdb/src/gdb/NEWS
|
||||
...
|
||||
c-x 4 a
|
||||
Bump version to 5.1.0.1.

@subheading Build the snapshot:

@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.}
|
||||
|
||||
@emph{Maintainer note: Other projects generate @file{README} and
|
||||
@file{INSTALL} from the core documentation. This might be worth
|
||||
pursuing.}

|

@subsubheading @file{gdb/version.in}

@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
|
||||
( 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.
|
||||
|
||||
@example
|
||||
$ ( cd gdb/src && cvs -q update )
|

@end example
|
||||
@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 cronjob.
|
||||
|
||||
@subheading Copy all the @file{.bz2} files to the ftp directory:
|
||||
for the @file{version.in} update @kbd{cronjob}.

@subheading Something about @kbd{gzip}'ing them.
|
||||
@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 Something about web pages?
|
||||
@subheading Re-pack the release with @code{gzip}
|
||||
|
||||
@subheading Something about documentation?
|
||||
@example

||||
$ cp */*/*.bz2 .
|
||||
$ bunzip2 -k -v *.bz2
|
||||
$ gzip -9 -v *.tar
|
||||
@end example
|
||||
|
||||
@subheading Cleanup the release tree
|
||||
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.
|
||||
|
||||
In particular you'll need to:
|
||||
@emph{Maintainer note: The release process could be changed to create
|
||||
@file{.tar} rather than @file{.tar.bz2} files.}
|
||||
|
||||
@section Check the release
|
||||
|
||||
Grab the @file{gdb.tar.bz2}, copy it to your local machine and then try
|
||||
a simple build using it.
|
||||
|
||||
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

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

news items

Remove any @kbd{OBSOLETE} code.

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.

@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
|
||||
|
||||
The files committed to the branch may also need changes merged into the
|
||||
trunk.
|
||||
|
||||
@section Post release
|
||||
|
||||
Remove any @code{OBSOLETE} code.
