<H3> 15.1.1 Version Identifiers </H3>
<!--docid::SEC131::-->
<P>
GDB's version is determined by the file <TT>`gdb/version.in'</TT>.
</P><P>
GDB's mainline uses ISO dates to differentiate between
versions. The CVS repository uses <VAR>YYYY</VAR>-<VAR>MM</VAR>-<VAR>DD</VAR>-cvs
while the corresponding snapshot uses <VAR>YYYYMMDD</VAR>.
</P><P>
GDB's release branch uses a slightly more complicated scheme.
When the branch is first cut, the mainline version identifier is
prefixed with the <VAR>major</VAR>.<VAR>minor</VAR> from of the previous release
series but with .90 appended. As draft releases are drawn from the
branch, the minor minor number (.90) is incremented. Once the first
release (<VAR>M</VAR>.<VAR>N</VAR>) has been made, the version prefix is updated
to <VAR>M</VAR>.<VAR>N</VAR>.0.90 (dot zero, dot ninety). Follow on releases have
an incremented minor minor version number (.0).
</P><P>
Using 5.1 (previous) and 5.2 (current), the example below illustrates a
typical sequence of version identifiers:
</P><P>
<DL COMPACT>
<DT>5.1.1
<DD>final release from previous branch
<DT>2002-03-03-cvs
<DD>main-line the day the branch is cut
<DT>5.1.90-2002-03-03-cvs
<DD>corresponding branch version
<DT>5.1.91
<DD>first draft release candidate
<DT>5.1.91-2002-03-17-cvs
<DD>updated branch version
<DT>5.1.92
<DD>second draft release candidate
<DT>5.1.92-2002-03-31-cvs
<DD>updated branch version
<DT>5.1.93
<DD>final release candidate (see below)
<DT>5.2
<DD>official release
<DT>5.2.0.90-2002-04-07-cvs
<DD>updated CVS branch version
<DT>5.2.1
<DD>second official release
</DL>
<P>
Notes:
</P><P>
<UL>
<LI>
Minor minor minor draft release candidates such as 5.2.0.91 have been
omitted from the example. Such release candidates are, typically, never
made.
<LI>
For 5.1.93 the bziped tar ball <TT>`gdb-5.1.93.tar.bz2'</TT> is just the
official <TT>`gdb-5.2.tar'</TT> renamed and compressed.
</UL>
<P>
To avoid version conflicts, vendors are expected to modify the file
<TT>`gdb/version.in'</TT> to include a vendor unique alphabetic identifier
(an official GDB release never uses alphabetic characters in
its version identifer).
</P><P>
Since GDB does not make minor minor minor releases (e.g.,
5.1.0.1) the conflict between that and a minor minor draft release
identifier (e.g., 5.1.0.90) is avoided.

<H3> 15.1.2 Branches </H3>
<!--docid::SEC132::-->
<P>
GDB draws a release series (5.2, 5.2.1, <small>...</small>) from a single
release branch (gdb_5_2-branch). Since minor minor minor releases
(5.1.0.1) are not made, the need to branch the release branch is avoided
(it also turns out that the effort required for such a a branch and
release is significantly greater than the effort needed to create a new
release from the head of the release branch).
</P><P>
Releases 5.0 and 5.1 used branch and release tags of the form:
</P><P>
<TABLE><tr><td>&nbsp;</td><td class=smallexample><FONT SIZE=-1><pre>gdb_N_M-YYYY-MM-DD-branchpoint
gdb_N_M-YYYY-MM-DD-branch
gdb_M_N-YYYY-MM-DD-release
</FONT></pre></td></tr></table></P><P>
Release 5.2 is trialing the branch and release tags:
</P><P>
<TABLE><tr><td>&nbsp;</td><td class=smallexample><FONT SIZE=-1><pre>gdb_N_M-YYYY-MM-DD-branchpoint
gdb_N_M-branch
gdb_M_N-YYYY-MM-DD-release
</FONT></pre></td></tr></table></P><P>
<EM>Pragmatics: The branchpoint and release tags need to identify when
a branch and release are made. The branch tag, denoting the head of the
branch, does not have this criteria.</EM>

<H2> 15.2 Branch Commit Policy </H2>
<!--docid::SEC133::-->
<P>
The branch commit policy is pretty slack. GDB releases 5.0,
5.1 and 5.2 all used the below:
</P><P>
<UL>
<LI>
The <TT>`gdb/MAINTAINERS'</TT> file still holds.
<LI>
Don't fix something on the branch unless/until it is also fixed in the
trunk. If this isn't possible, mentioning it in the <TT>`gdb/PROBLEMS'</TT>
file is better than committing a hack.
<LI>
When considering a patch for the branch, suggested criteria include:
Does it fix a build? Does it fix the sequence <KBD>break main; run</KBD>
when debugging a static binary?
<LI>
The further a change is from the core of GDB, the less likely
the change will worry anyone (e.g., target specific code).
<LI>
Only post a proposal to change the core of GDB after you've
sent individual bribes to all the people listed in the
<TT>`MAINTAINERS'</TT> file <TT>;-)</TT>
</UL>
<P>
<EM>Pragmatics: Provided updates are restricted to non-core
functionality there is little chance that a broken change will be fatal.
This means that changes such as adding a new architectures or (within
reason) support for a new host are considered acceptable.</EM>

<H2> 15.3 Obsoleting code </H2>
<!--docid::SEC134::-->
<P>
Before anything else, poke the other developers (and around the source
code) to see if there is anything that can be removed from GDB
(an old target, an unused file).
</P><P>
Obsolete code is identified by adding an <CODE>OBSOLETE</CODE> prefix to every
line. Doing this means that it is easy to identify something that has
been obsoleted when greping through the sources.
</P><P>
The process is done in stages -- this is mainly to ensure that the
wider GDB community has a reasonable opportunity to respond.
Remember, everything on the Internet takes a week.
</P><P>
<OL>
<LI>
Post the proposal on <A HREF="mailto:gdb@sources.redhat.com">the GDB mailing
list</A> Creating a bug report to track the task's state, is also highly
recommended.
<LI>
Wait a week or so.
<LI>
Post the proposal on <A HREF="mailto:gdb-announce@sources.redhat.com">the GDB
Announcement mailing list</A>.
<LI>
Wait a week or so.
<LI>
Go through and edit all relevant files and lines so that they are
prefixed with the word <CODE>OBSOLETE</CODE>.
<LI>
Wait until the next GDB version, containing this obsolete code, has been
released.
<LI>
Remove the obsolete code.
</OL>
<P>
<EM>Maintainer note: While removing old code is regrettable it is
hopefully better for GDB's long term development. 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.</EM>

<H2> 15.4 Before the Branch </H2>
<!--docid::SEC135::-->
<P>
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 GDB from even
building. If you can't get the problem fixed, document it in the
<TT>`gdb/PROBLEMS'</TT> file.

<H3> Prompt for <TT>`gdb/NEWS'</TT> </H3>
<!--docid::SEC136::-->

People always forget. Send a post reminding them but also if you know
something interesting happened add it yourself. The <CODE>schedule</CODE>

<H3> Review <TT>`gdb/README'</TT> </H3>
<!--docid::SEC137::-->

Grab one of the nightly snapshots and then walk through the

These pages also need to be regenerate using <CODE>index.sh</CODE>.

<DT><TT>`download/onlinedocs/'</TT>
<DD>You need to find the magic command that is used to generate the online
docs from the <TT>`.tar.bz2'</TT>. The best way is to look in the output
from one of the nightly <CODE>cron</CODE> jobs and then just edit accordingly.
Something like:

The release is out but you're still not finished.
</P><P>
<A NAME="SEC168"></A>
<H4> Commit outstanding changes </H4>
<!--docid::SEC168::-->
<P>
In particular you'll need to commit any changes to:

<UL>
<LI>
<TT>`gdb/ChangeLog'</TT>

<TT>`gdb/version.in'</TT>
<LI>
<TT>`gdb/NEWS'</TT>

</UL>
<P>
<A NAME="SEC169"></A>
<H4> Tag the release </H4>
<!--docid::SEC169::-->
<P>
Something like:
</P><P>
<TABLE><tr><td>&nbsp;</td><td class=smallexample><FONT SIZE=-1><pre>$ d=`date -u +%Y-%m-%d`
$ echo $d
2002-01-24

$ ( cd insight/src &#38;&#38; cvs -f -q tag gdb_5_2-$d-release )
</FONT></pre></td></tr></table></P><P>
Insight is used since that contains more of the release than
GDB (<CODE>dejagnu</CODE> doesn't get tagged but I think we can live
with that).
</P><P>
<A NAME="SEC170"></A>
<H4> Mention the release on the trunk </H4>
<!--docid::SEC170::-->
<P>
Just put something in the <TT>`ChangeLog'</TT> so that the trunk also
indicates when the release was made.
</P><P>
<A NAME="SEC171"></A>
<H4> Restart <TT>`gdb/version.in'</TT> </H4>
<!--docid::SEC171::-->
<P>
If <TT>`gdb/version.in'</TT> does not contain an ISO date such as
<KBD>2002-01-24</KBD> then the daily <CODE>cronjob</CODE> won't update it. Having
committed all the release changes it can be set to
<TT>`5.2.0_0000-00-00-cvs'</TT> which will restart things (yes the <KBD>_</KBD>
is important - it affects the snapshot process).
</P><P>
Don't forget the <TT>`ChangeLog'</TT>.
</P><P>
<A NAME="SEC172"></A>
<H4> Merge into trunk </H4>
<!--docid::SEC172::-->
<P>
The files committed to the branch may also need changes merged into the
trunk.
</P><P>
<A NAME="SEC173"></A>
<H4> Revise the release schedule </H4>
<!--docid::SEC173::-->
<P>
Post a revised release schedule to <A HREF="mailto:gdb@sources.redhat.com">GDB
Discussion List</A> with an updated announcement. The schedule can be
generated by running:
</P><P>
<TABLE><tr><td>&nbsp;</td><td class=smallexample><FONT SIZE=-1><pre>$ ~/ss/schedule `date +%s` schedule
</FONT></pre></td></tr></table></P><P>
The first parameter is approximate date/time in seconds (from the epoch)
of the most recent release.
</P><P>
Also update the schedule <CODE>cronjob</CODE>.
