This document describes what has changed in Turbine on a
particular date. When we release these changes can be tracked
on a release to release basis, but for now we'll just use
the date to keep track of major changes.
The following changes are a result of trying to order the
initialization of the services according to order they
are listed in the TR.props file. To effect this change, the
Configuration class from Velocity was used because it
internally keeps properties in order. Variants of the
Configuration are used in three projects now so we should
work on putting it somewhere so it can be reused. For
now it's being pulled from the Velocity JAR included in
the Turbine distribution but this will change when we
find a home for the Configuration class.
-
Email classes
Added ability to set SMTP-From headers, to direct all 'delivery
failed' messages to a separate mailbox.
TR.props also changed to allow for an address for all messages
with failed delivery.
-
Pull Service
Added getTool() method to allow access to request level
tools in the context without having to do an annoying cast.
-
Scheduler Service
Cleaned up logging in the WorkerThread class.
-
HttpUtils class added
A place to hang HTTP utility routines. Currently provides date
formatting and cache header control. Unfortunate name conflict
with HttpUtils class in the javax.servlet package
,
but consistant with current utility class naming scheme.
-
Configuration functionality add to services.
Services now have access to a Configuration object that
can be used instead of a Properties object. Hopefully
we can eliminate the use of Properties all together.
Right now the Velocity Service is the example of how
to use the Configuration object inside a service.
-
Torque
The Torque tasks have been cleaned up. Tried to place
as much of the information required for generation
in a configuration file. Hopefully this will allow
us to add functionality to the generating process without
having to alter the ant task code.
-
Velocity Service
Updated to keep in step with the changes that are
being made as Velocity moves to 1.0. Velocity can
now be fully configured from the TR.props. In the
Velocity service the subset of the TR.props that
pertain to the Velocity service are extracted
and passed on to the Velocity Runtime. This should
make the Velocity service easier to configure.
-
Template Services
TemplateService was reworked to associate template file name
extensions with TemplateEngineService implementations and
delegate to the appropriate registered service. The easiest
wasy to write such a TemplateEngineService implementation is to
extend the new BaseTemplateEngineService class.
-
BasePeer
Added database.query.debug
flag for control of
query logging at the DEBUG
level.
-
SQL Logging Facility
A new SQL logging facility has been defined, initially set to
ERROR level. Currently, the logging level must be loosened to
DEBUG to produce logging output.
-
BasePeer
Dropped database.query.debug
from BasePeer in favor
of logging SQL queries to the sql
facility instead.
at DEBUG level.
-
Added SequencedHashtable and BufferCache Collections classes
SequencedHashtable
is a Hashtable whose keys are
sequenced. The sequencing of the keys allow easy access to the
values in the order which they were added in. Thread safe.
BufferCache
is a fixed length object cache
implementing the LRU algorithm. Convenient for buffering
recently used objects.
-
Service Names and TurbineResources.properties
Each service's SERVICE_NAME constant has been changed from the
name of Turbine's implemtating class to the name of the
service's interface.
-
TurbineServices
Bug fix to getProperties(String name) to properly handle
internal use of Configuration class for multi-value keys. A
ClassCastException was being thrown erroneously, contradicting
the behavior noted in the JavaDoc. JavaDoc was updated to
recommend getConfiguration(String name) for multi-value keys.
-
TurbineUploadService
Bug fix to close FileItem OutputStream after data has been
written into it.
-
MultiPartEmail and FileItem (upload service)
Made FileItem implement the javax.activation.DataSource
interface, and had MultiPartEmail accept DataSource
specified attachments.
-
HtmlEmail
Now will only form a multipart/alternative body part if
both the HTML and text parts are specified. If either is
omitted, only the other will be used as the body.
-
StringUtils and VelocityEmail
Text wrapping capabilities added to StringUtils. Hooks added to
VelocityEmail to make use of this new StringUtils functionality.
-
Security
Users/Roles/Groups security was extensively revamped in a
branch. Now merged back into the HEAD.
-
BaseUnicastRemoteService
Added a base implementation of a java.rmi.server.UnicastRemoteObject
as a Turbine Service.
-
TimeSelector
Integrated a new org.apache.turbine.util.TimeSelector component
into org.apache.turbine.util.parser.BaseValueParser.
