Feedback on my project proposal

I have posted my application on the GSOC site for the project "Convert
tomcat valves to filters" , Can anyone give their comment on the same.......

Thanks

Really? Where did you find those? I'm not aware of any.

That sounds like a sensible approach. Some valves will be easier than others.

You will need to think about configuration. Valves are configured at Engine,
Host and Context level with Tomcat specific configuration. Filters are
configured at Context level with servlet spec configuration. You'll also need to
consider how they will interact with the new Async support in the Servlet 3.0 spec.

The info on http://wiki.apache.org/general/SummerOfCode2009 is the best source
of information.

I suggest that you familiarise yourself with the Tomcat source code, starting
with building trunk (Tomcat 7 development branch) from
http://svn.apache.org/repos/asf/tomcat/trunk

There aren't really any valve bugs that need fixing so I suggest you take a look

Feedback provided in the GSOC app and repeated below. Feel free to discuss your
ideas regarding these questions on the dev list.

Mark

Feedback:
Good first draft. There are a couple of areas where I would like to see a little
more information:

   1. There are many more valves than the 6 you listed.
   2. The filter requires a ServletContext at initialisation. How might you
handle this for a filter defined at the Engine/Host level?
   3. Authentication will require access to Tomcat internals. Is a filter the
right solution for these valves? What might a better approach be? What about JSR
196?

tomcat 6 session replication issues

Hi,

I've been having issues with tomcat session replication. I have 20 tomcat servers running in a cluster mode, behind an Apache load balancer. The tomcat version is 6.0.18 on CentOS 5.1. Running the cluster using the DeltaManager seems to be working fine, however when I try to use the BackupManager for session replication, I get the following entries in the logs:

Of course the above entry is just one of many, for the different hosts. Searching the mailing lists, I found this post http://markmail.org/message/jv4dykh7fdhr4mvp which looks like the same problem I am having. The outcome of that thread states that the problem is fixed by a patch in revision 618823, so I compiled a version of the current 6.x trunk (rev 759722) and deployed it to all the servers. However, the problem is still appearing. I've attached a copy of the current server.xml ( it is common to all tomcat instances ).

I've done a thread dump on one of the servers when these errors started appear ing, and the output is attached, thread_dump.txt (removed threads that were running by our application).

This problem is reproducable each time I restart the servers. At this stage, I'm clueless on what to try next, so I'm looking forward to your replies.


Regards,
Jim.

Attached: server.xml, thread_dump.txt

Re: my proposal for "re implement tomcat valves as filters"

Feedback provided in the GSOC app and repeated below. Feel free to discuss your
ideas regarding these questions on the dev list.

Mark

Feedback:
Good first draft. There are a coupe of areas I would like to see more detail on:

   1. Impact of Servlet 3 and async processing.
   2. The filter requires a ServletContext at initialisation. How might you
      handle this for a filter defined at the Engine/Host level?
   3. Authentication will require access to Tomcat internals. Is a filter the
      right solution for these valves? What might a better approach be? What
      about JSR 196?

I would also suggest you spend a little time to build Tomcat from source
(http://svn.apache.org/repos/asf/tomcat/trunk). Once you have Tomcat building,
I'd suggest looking at the AccessLogValve and how that might be converted to a
Filter to give you a better ide of the issues involved and how long things might
take.

When a part of a webapp requires an SSL connection with a client certificate
there should be an SSL renegotiation to request a client certificate from the
browser.

This is the configuration I added to an webapp that already uses an SSL
connector:

<login-config id="LoginConfig_1">
                <auth-method>CLIENT-CERT</auth-method>
                <realm-name>WPS</realm-name>
</login-config>

<security-constraint id="SecurityConstraint_1">
                <web-resource-collection id="WebResourceCollection_1">
                        <web-resource-name/>   
                        <url-pattern>/LoginWithCert.do</url-pattern>
                        <http-method>DELETE</http-method>
                        <http-method>GET</http-method>
                        <http-method>POST</http-method>
                        <http-method>PUT</http-method>
                        <http-method>HEAD</http-method>
                </web-resource-collection>
                <user-data-constraint id="UserDataConstraint_4">
                        <transport-guarantee>CONFIDENTIAL</transport-guarantee>
                </user-data-constraint>
</security-constraint>

Requests to /LoginWithCert.do require an SSL connection, if there isn't one,
but no client certificate is requested.

10th anniversary

Hi,

Seems this  year Tomcat has 10 year anniversary since
being part of ASF. I plan to create some artwork and
edit the heritage.html page, probably add few more.

It would be nice to list all the initial committers
on that page and get some more info on the history
from the early days.

If anyone has some nice story to share, I'd love
to publish that as well, so she/he can just mail me
or whatever.

Regards

Great initiative, ++1
(though I can't contribute anything about the relevant time).
