Ole Solberg commented on DERBY-3982:
------------------------------------
A short writeup on usage:
a) -DderbyTesting.oldReleasePath=/usr/local/share/java/derby/lib
-DderbyTesting.oldVersionsPath=/usr/local/share/java/derby/lib/versions
Use jars at /usr/local/share/java/derby/lib and test upgrade from the
versions listed in /usr/local/share/java/derby/lib/versions
'versions' might look like this:
# Ignore lines not matching the regexp: "^[\\d]+\\.[\\d]+\\.[\\d]+\\.[\\d]"
10.0.2.1 // 10.0.2.1 (incubator release)
10.1.1.0 // 10.1.1.0 (Aug 3.2005 / SVN 208786)
10.1.2.1 // 10.1.2.1 (Nov 18.2005 / SVN 330608)
10.1.3.1 // 10.1.3.1 (Jun 30.2006 / SVN 417277)
10.2.1.6 // 10.2.1.6 (Oct 02.2006 / SVN 452058)
10.2.2.0 // 10.2.2.0 (Dec 12.2006 / SVN 485682)
10.2.2.1 // (Special test version / SVN 538595)
10.3.1.4 // 10.3.1.4 (Aug 1.2007 / SVN 561794)
10.3.3.0 // 10.3.3.0 (May 12.2008 / SVN 652961)
10.4.1.3 // 10.4.1.3 (April 24.2008 / SVN 648739)
10.4.2.0 // 10.4.2.0 (September 05, 2008 / SVN 693552)
10.4.2.1 // (Special test version / SVN 706043)
b) -DderbyTesting.oldReleasePath=/usr/local/share/java/derby/lib
Use jars at /usr/local/share/java/derby/lib and test upgrade from the
versions listed as defaults (currently as listed in 'VERSIONS').
c) -DderbyTesting.oldVersionsPath=/usr/local/share/java/derby/lib/versions
Use jars fetched from 'http://svn.apache.org/repos/asf/db/derby/jars' and
test upgrade from the versions listed in
/usr/local/share/java/derby/lib/versions.
Will warn that 10.2.2.1 and 10.4.2.1 are not available
d) None of -DderbyTesting.oldReleasePath and -DderbyTesting.oldReleasePath are
given
Use jars fetched from 'http://svn.apache.org/repos/asf/db/derby/jars' and
test upgrade from the versions listed as defaults (currently as listed in
'VERSIONS').
> Add a facility to override the default set of old versions to be tested in
> the upgrade tests.

> Project: Derby
> Issue Type: Improvement
> Components: Test
> Affects Versions: 10.5.0.0

> Priority: Minor

> In my testing I have seen a need for performing upgrade testing from
> local/internal non-public "versions" of Derby.
> That is, having local/internal changes to some older branch and allowing
> upgrade testing from this (not yet public) version.
> One solution is to locally modify the 'VERSIONS' table of the upgradetests
> '_Suite', but this means modifying the source for each such case.
> A more flexible solution is to override the default versions (given in
> 'VERSIONS') by using a property giving a file which lists the versions to
> test upgrade from. The location to local version jars can currently be given
> by the 'derbyTesting.oldReleasePath' property. The list of versions could be
> given by a property 'derbyTesting.oldVersionsPath'.
> This will also easily allow us to skip testing upgrade from a specific
> version. (This can already be done by not having the version jars available.)
> The list of versions given via the property should be used whether versions
> (jars) are available locally (as given by the 'derbyTesting.oldReleasePath'
> property or fetched from the Apache Derby svn repository
> ('http://svn.apache.org/repos/asf/db/derby/jars').
> I have a patch for this which I will submit for review.
