Subject Request to move IncludeTransformer into next release
Date Thu, 15 Sep 2005 21:10:08 GMT

We use the org.apache.cocoon.transformation.IncludeTransformer class
from the scratchpad block in Cocoon 2.1.6. We've just looked closely at
2.1.7 and discovered that the scratchpad block is not part of the

I understand why this has been done, but I would like to request that
this class is shifted to a more "stable" block/core area for the next
release, so that we don't need to add it in explicitly. What is the
proper way to initiate this?

I believe this class belongs in the next release because:

- we have used it successfully in production for several months, under
high load

- it provides critical (for us) cache functionality not provided by
CIncludeTransformer or XIncludeTransformer:  it retains or "takes on"
the cache validity of its included content. CInclude only provides
expiry/time-based validity - the included content's validity is ignored.
XInclude isn't Cacheable.

IncludeTransformer enables us to tweak our caching very finely for
content coming from our database - updates to the database trigger a
cache clear event on the Cocoon server. With the scratchpad
IncludeTransformer _any_ pipeline that includes that data at any point
will be removed from the cache immediately. This is exactly the
functionality we require.

In the meantime of course we will pull this class from trunk.
