<note>The product build related sections of this document are still 
quite thin - they're mainly bullet points almost in checklist style.  
If you don't fully understand the procedures in this document, then 
you probably should ask for help first!</note> 


<anchor name="intro"/>
<s2 title="Introduction">
  <p>A selection of brief checklists for committers and developers 
  about build procedures for the &xslt4j; community.  Community input 
  is appreciated; if you have questions, please ask on xalan-dev.</p> 
</s2>


<anchor name="developers"/>
<s2 title="Developer Guidelines">
<note>This section is meant to become a set of guidelines for all &xslt4j;
committers and developers who wish to submit patches.  It's still in progress; 
suggestions to xalan-dev@xml.apache.org appreciated.</note> 
  <p>The project's technical mailing list for all committers and developers 
  interested in the API and inner workings is 
  <jump href="mailto:xalan-dev@xml.apache.org">xalan-dev@xml.apache.org</jump>; 
  it's a good idea to subscribe if you plan to work on &xslt4j;.  Logs of all CVS 
  commits are automatically sent to <jump href="mailto:xalan-cvs@xml.apache.org">xalan-cvs@xml.apache.org</jump>, although 
  discussions should happen on xalan-dev.  You can read more <jump href="http://xml.apache.org/mail.html">about mailing lists.</jump></p>
  <p>&xslt4j; is a fairly mature project; one where most committers and many 
  users expect that the daily build will be mostly functional.  Very risky changes 
  or major architecture updates should be discussed ahead of time or committed onto 
  branches.</p> 
  <p>Developers should always run the Smoketest before checking in files or 
  submitting patches to the list.  If the Smoketest does not pass, you should 
  either fix whatever you broke or get consensus from xalan-dev that 
  it's OK to break the Smoketest temporarily.  The Smoketest is a selection of 
  API functionality tests and a pass through a wide variety of XSLT conformance 
  tests that ensure basic functionality.  You can also read a full set of 
  <jump href="http://xml.apache.org/xalan-j/test/overview.html">documentation about the tests</jump>.</p>
  <p>
  (Smoketest doc is TBD!)
<source>cvs co xml-xalan/java xml-xalan/test
cd xml-xalan/java
build smoketest
# Ant build will fail if smoketest fails.
</source>
</p>
</s2>


<anchor name="gump"/>
<s2 title="Nightly GUMP builds">
  <p>GUMP is... there really is no easy way to define 'GUMP'.  It's basically 
  a meta-build system designed to do CVS updates and Ant builds of multiple 
  projects simultaneously.  Luckily, GUMP is a subproject of jakarta-alexandria that 
  includes a complete set of <jump href="http://jakarta.apache.org/gump/">GUMP documentation</jump>.</p> 
  <p>Some committers at jakarta also provide a GUMP service, which runs actual 
  builds nightly of nearly all xml and jakarta projects.  The 
  <jump href="http://jakarta.apache.org/builds/gump/">results of nightly builds</jump> 
  are posted daily, and the actual 
  <jump href="http://xml.apache.org/dist/xalan-j/nightly/">&xslt4j; nightly build</jump> is also posted (when it succeeds).</p>
  <p>Discussions about GUMP itself happen on the alexandria-dev@jakarta.apache.org mailing list.  
  Note: nightly builds are just that - automated builds run nightly, without human intervention.  
  Use them at your own risk!</p>
</s2>


<anchor name="builds"/>
<s2 title="Running Product Builds - Overview">
<p>Official builds of &xslt4j; require a few more steps than simply doing 
'build dist smoketest'.  This is a quick checklist of the steps; if you are 
not comfortable following this list, then please seek help on xalan-dev.</p> 

<s3 title="Release Types">
<p>Official builds come in several flavors:</p>
<ul>
<li>Major version releases: when significant new or changed functionality comes out, 
we bump up the major build number; i.e. from 2.3 to 3.0.  This is fairly rare; 
anyone reading xalan-dev will know when this is happening.<br/><br/></li>
<li>Minor version releases happen when we fix bugs or make moderate improvements to 
the product.  These are moving from 2.3 to 2.4; they should be planned out.<br/><br/></li>
<li>Maintenance point releases are when we find bugs in an existing version and fix them without 
adding new functionality; these go from 2.3 to 2.3.1.  They should be done on a 
branch if the mainline development has already moved forward; the point is to 
make critical bugfixes for existing customers who want to stay on the stable release.<br/><br/></li>
<li>Developer releases are very ad hoc; they represent a chunk of progress along the 
HEAD of our CVS tree towards a new major or minor release. The developer release 
versions would be going from 2.3 to a new 2.4.D1 - the developer release can is somewhat 
like a 'beta' towards a new 2.4 minor version release.  Quality standards for developer 
releases are much less stringent than other releases.<br/><br/></li>
</ul>
</s3>

<s3 title="Condensed Build Checklist">
<p>A very brief list of stages in running a build.</p>
<ol>
<li>Email xalan-dev with build plan.<br/><br/></li>
<li>Verify all code changes are checked in.<br/><br/></li>
<li>Verify any doc updates for code changes are in.<br/><br/></li>
<li>Update build numbers in doc, code, and build scripts.<br/><br/></li>
<li>Do a clean checkout and tag the sources.<br/><br/></li>
<li>build dist smoketest -logfile ..\dist.log<br/><br/></li>
<li>Verify smoketest passed; check docs built with new build numbers.<br/><br/></li>
<li>PGP/GPG sign all .zip/.tar.gz distribution files (distros).<br/><br/></li>
<li>Copy distros up to the website.<br/><br/></li>
<li>Update website documentation set.<br/><br/></li>
<li>Email xalan-dev with build notice!<br/><br/></li>
</ol>
</s3>

</s2>

<anchor name="builds2"/>
<s2 title="Running Product Builds - Details">
<p>This section is still in progress, but should have all the basics. 
You should already have read the <link anchor="builds">build overview</link> above and you should already be 
familiar with our build.xml script and development processes.</p> 

<s3 title="Pre-Build Steps">
<p>Preparation before you run a build.</p>
<ul><!-- I'd prefer to use ol's, but the start="num" attr isn't supported in Stylebook -->
<li>Email xalan-dev with build plan.</li>
</ul>
<p>Apache projects are communities: you should always let the community know what 
the plans for builds are.  The xalan-dev mailing list is the primary communication 
mechanisim for committers and developers working on &xslt4j;; you may also wish 
to cc: the xalan-j-users list to let other users and folks know what's coming. 
For major releases you may also want to cc: the general@xml.apache.org list so that 
other xml.apache.org projects know our plans, although this is not required.</p>
<ul>
<li>Verify all code changes are checked in.</li>
</ul>
<p>Ensure that any code changes you're planning to have in this release are actually 
checked in; make sure any open work by other committers is in a stable state. 
You should also review any other projects we're dependent on and make sure 
that (when possible) we've updated to the latest version of their .jar files: 
like xercesImpl.jar, ant.jar, etc.  Note that occasionally we will have a specific 
development need to stay with a different version of these projects.</p>
</s3>

<s3 title="Updating Doc And Version Numbers">
<p>Getting documentation and version numbers in sync.</p>
<ul>
<li>Verify any doc updates for code changes are in.</li>
</ul>
<p>Check that the documentation is up to date.  Make sure that any new 
features or major functionality changes are properly documented.</p>
<p>Update the commits list and the 'what was done' list in xdocs/sources/xalan/readme.xml 
and whatsnew.xml.  Note that currently some of the status information for the 
xsltc portion of &xslt4j; is stored separately in xsltc_history.xml and XSLTCDONE
</p>
<p>Check in all your work!</p>

<ul>
<li>Update build numbers in doc, code, and build scripts.</li>
</ul>
<p>Currently the actual version number is stored in several places in 
the CVS tree - we hope to improve this in the future by using the Ant 
build system's filtering capabilities.</p>
<p>Once you know what the version number should be, you'll need to update 
it in a number of places - both for the product itself, for the build 
system, and for the documentation.  If you don't understand how to update 
any of these files, then please get help - <b>don't</b> just try to wing it.</p>
<note>Version.java should replace XSLProcessorVersion.java; we just haven't 
gotten around to doing it yet... -Shane</note>
<ul>
<li>src/org/apache/xalan/Version.java  (The NEW 2.2+ actual code version of the processor - currently just a wrapper for XSLProcessorVersion, which is deprecated and will be removed after 2.2 gold ships in favor of the simpler Version class, which uses static accessor methods instead of static strings)<br/><br/></li>
<li>src/org/apache/xalan/processor/XSLProcessorVersion.java  (The old 2.2 and earlier actual code version of the processor)
Update the int format VERSION, RELEASE, MAINTENANCE, and DEVELOPMENT numbers, each as an integer. The version string will be automagically built from these.<br/><br/></li>
<li>build.xml 
Update the following lines for each version field:<br/>
&lt;property name="version.VERSION" value="2"/><br/>
&lt;property name="version.RELEASE" value="4"/><br/>
&lt;property name="version.DEVELOPER" value="D"/>&lt;!-- Set this to "D" if a developer release; blank "" if maintenance point release -->
&lt;property name="version.MINOR" value="1"/>&lt;!-- EITHER the developer release number, or a maintenance point release number -->
<br/><br/></li>
<li>src/org/apache/xalan/xpath/xml/XSLTInfo.properties (only if needed for an XSLT spec change, this will be very rare. This is not the processor version, but the spec version)  
You probably shouldn't even <b>think</b> about updating this one, so pretend I 
never mentioned it, OK?<br/><br/></li>

<li>xml-xalan\java\xdocs\sources\entities.ent (xslt4j-current) documentation updates<br/><br/></li>
<li>xml-xalan\java\xdocs\sources\xalan-jsite (document id="index" label="Xalan-Java x.x")<br/><br/></li>

<li>If you updated xercesImpl.jar or any other dependent .jar files, 
make sure you update the documentation to reflect this. xml-xalan\java\xdocs\sources\entities.ent (xml4j-used)<br/><br/></li>
</ul>
<p>I did remind you to check in all your work, didn't I?</p>
</s3>


<s3 title="Run A Candidate Distribution Build">
<p>Get clean sources and build a distribution and (at least) the smoketest.</p>
<ul>
<li>Do a clean checkout and tag the sources.</li>
</ul>
<p>Of course, you checked in all your earlier work to the CVS repository, right?</p>
<p>The safest way to perform a build for distribution is to check out a fresh 
new copy of the repository from CVS.  This avoids any potential problems with 
uncommitted changes or extra files on your local machine.</p>
<p>Check out a new copy of both xml-xalan/java and xml-xalan/test repositories 
to a blank directory on your local machine.  You then need to tag the files in 
the repository with a marker noting that these versions are the actual ones 
being used in the build (you could actually do this after running the build below). 
Use the CVS tag command to add the tag to both repositories (/java and /test). 
The tag name should be something like 'xalan-j_2_4'; look at the log of any file 
to see the exact format of previous builds.</p>


<ul>
<li>build dist smoketest -logfile ..\dist.log</li>
</ul>
<p>The above command will build the 'dist' or distribution .zip/.tar.gz 
files, as well as building the full product plus all documentation.  It will then 
run the smoketest, and saves all of it's output in ..\dist.log.  Note that this 
will take up a moderate amount of space, especially when building the .tar.gz files, 
so ensure you have plenty of disk space first.</p>

<ul>
<li>Verify smoketest passed; check docs built with new build numbers.</li>
</ul>
<p>Review the dist.log quickly to ensure there were no build errors.  
Note that you can ignore any 'warnings' from the javadoc target; however any 
'error's in the documentation must be fixed.</p>
<p>The logfile should also report the Smoketest results at the end; if it does 
not say that the Smoketest passed, then you must fix the test results before 
posting the build.  Even for developer's builds, we must ensure that at least 
the Smoketest passes.  For major or minor releases, we should also perform more 
testing to ensure stability.  More detailed log files for the Smoketest can 
be found in the xml-xalan/test/smoketest/ directory.</p>
<p>You should also test that the documentation built properly, and that it 
has the proper build or release number that you edited above.</p>
<p>IMPORTANT: if you changed any files at all, be sure to check in your work 
and re-start this process!</p>

</s3>

<s3 title="Code Signing and Posting">
<p>Sign the distribution units so end-users can trust them, then copy to the website.</p>
<ul>
<li>PGP/GPG sign all .zip/.tar.gz distribution files (distros).</li>
</ul>
<p>As a security measure, all xml.apache.org projects must sign or otherwise 
ensure the integrity of their public distributions.  This is most commonly done 
by signing the actual .zip/.tar.gz files with your personal PGP or GPG key. 
Note that you must sign the files before copying them up to the website.</p>
<p>Two prerequisites to signing the distribution are: 1) you must have a 
personal PGP or GPG key, and 2) the public half of your key must be in the 
appropriate KEYS file before you begin a build.  If you hadn't previously checked 
in your public key to the KEYS file before beginning this whole process, you'll 
have to go back and start again.</p>
<note>We need some good links on getting <jump href="http://web.mit.edu/network/pgp.html">PGP</jump> 
and <jump href="http://www.gnupg.org/">GPG</jump>, and on actually 
code signing and verifying signatures.  Jakarta has some, but they're 
scattered. This would be a good volunteer project for someone.</note>
<p>Sign every .zip and .tar.gz file with your personal key, and make a detached 
text file with the signature - this will usually create a 
foo.zip.asc or foo.zip.sig file for each foo.zip file you sign.</p>
<ul>
<li>Copy distros up to the website.</li>
</ul>
<p>You'll need to copy all of the distros plus all of your 
detached signature files to the website so people can download them.  Note 
that apache.org machines generally do not allow inbound ftp, so you'll need to 
either scp them or login to the apache machines and use scp or pftp from there 
outbound to some server that you've copied them to.</p>
<p>(Subject to change as www.apache.org/dist gets ready for mirroring) 
You'll need to log on to xml.apache.org (which is a separate machine 
from cvs.apache.org) and upload the files to /www/xml.apache.org/xalan-j/dist</p>
<p>You should also update the distribution directory's html files 
to note the new build numbers.  Carefully edit the .htaccess file 
to update the 'Latest Stable Build' and 'Latest Developers Build' lines  
as needed.  If you don't understand the format of this file, ask for help.</p>

</s3>

<s3 title="Post-Build Docs and Email">
<p>Update the live website doc and let the community know you're done!</p>
<ul>
<li>Update website documentation set.</li>
</ul>
<p>Now that the distribution is available for downloading, you should also 
update the static copy of the documentation that's posted to xml.apache.org.  
I'll leave this to Donald Leslie to document, since he has 
it all organized.  (Plus I'm out of time!)</p>

<ul>
<li>Email xalan-dev with build notice!</li>
</ul>
<p>After everything is posted, you need to let the community know that 
a new build is available.  Write up a short email announcing this with just 
a couple of the highlights of the new build, and a link to the 
distribution area.</p>

<p>Make the subject something like:  [ANN] Xalan-J 2.x Point/Developers/Whatever Release posted to xml.apache.org
and send your email to:  general@xml.apache.org, xalan-dev@xml.apache.org, xalan-j-users@xml.apache.org.  Note 
that for developers releases, you can omit the general@xml.apache.org address if you 
don't think it will be of interest to the larger audience.
