Re: svn commit: r1827439 - /ofbiz/ofbiz-framework/trunk/framework/common/servicedef/services.xml

[Michael Brohl-3]

Mmhhh, Jacques,

I think this is problematic because it ties a special implementation for
Tomcat to the service. I didn't see this anywhere else.

The issue (https://issues.apache.org/jira/browse/OFBIZ-10304) is a bit
unclear and I don't get the purpose of this change.

Can you please explain more clearly which problem this changes solves
and why we'll need org.apache.catalina.connector.RequestFacade as the type?

Thanks,

Michael

Michael,

I commited
http://svn.apache.org/viewvc/ofbiz/ofbiz-framework/trunk/framework/webapp/src/main/java/org/apache/ofbiz/webapp/control/ContextFilter.java?r1=1813679&r2=1813678&pathrev=1813679 


Where I added a wrapper. Then for "Tomcat SSO" (OFBIZ-10047) James committed
http://svn.apache.org/viewvc/ofbiz/ofbiz-framework/trunk/framework/common/servicedef/services.xml?r1=1819133&r2=1819132&pathrev=1819133

If I had not committed the wrapper in ContextFilter.java beforehand, James would not have been allowed to commit

<attribute name="request" mode="IN" type="javax.servlet.http.HttpServletRequest" optional="true"/>

Because it's then rejected, because then the userLogin service actually receive an org.apache.catalina.connector.RequestFacade (RequestFacade
implements HttpServletRequest.)

You can easily check by svn updating to r1819133 and removing the wrapper in ContextFilter.java.

You are right that it ties OFBiz to Tomcat. We took this decision sometimes ago and we no longer support other webapp servers OOTB, nor tools like Jetty.

So OFBiz OOTB totally depends on Tomcat as the build.gradle file shows. So I think it's safe to use a RequestFacade there.

If an user feels the need to use another webapp servers or Jetty, I think changing that would not be the most of the worries (the rest being much more
frightening, I know I did it once with Geronimo).

Since the check is done at the service level, it's hard to do otherwise But I must say I did not dig too much and it's maybe possible, we can discuss
that...

Jacques

Something else must be wrong Jacques, I can't understand what you're saying
in the ticket description or in your reply above but I do know the
following:
OFBiz is perfectly capable of knowing that
org.apache.catalina.connector.RequestFacade
implements the javax.servlet.http.HttpServletRequest and it should pass
type validation without errors.

Since we know that, this commit becomes unnecessary.

Regards
Scott

Not only is this commit unnecessary, but also breaks one of the best
features in Object Oriented Programming -- polymorphism -- for no value
that I can see anywhere at all.

Also by saying we depend fully on Tomcat and we should write code that
further enforces that idea instead of making our architecture more modular
is a real bad idea IMO.

Did you try what I said?

You can easily check by svn updating to r1819133 and removing the wrapper
in ContextFilter.java.

Maybe we need to revert Tomcat SSO then?

A thorough review of that feature is actually on my todo list since some
time, after I have noticed some potential design issues.

BTW, forgot to say but the proposed feature at OFBIZ-10307 could be also used locally (dropping the CORS part).
I tested it initially before crossing CORS (pun intended) and it works perfectly. It's safe because, like JSESSION, it's build upon safe AutoLogin
cookies
So we could use it instead of ExternalLoginKey or TomcatSSO. I did not test in a cluster environment though...

Anyway just saying for now.

I have issues with multiple decisions all around that same topic that
never got community consensus. Changes to cookies, http redirects,
authentication, and other commits that did not get a proper review
from the community. Such major design decisions need proper review IMO

I don't need to try anything, I *know* that the service engine is supposed
to accept a concrete class of an interface if the interface is specified as
the attribute type.

Either the service engine is broken by not accepting concrete
implementations, or the bug report is incorrect.

Neither, it's "unfortunate", and a bit complicated.

Tomcat servlet4preview was introduced with Tomcat 8.5
https://tomcat.apache.org/tomcat-8.5-doc/api/org/apache/catalina/servlet4preview/package-summary.html

Before James introduced Tomcat SSO, we had only one service passing a javax.servlet.http.HttpServletRequest to a service: payPalCheckoutUpdate.

AFAIK, we have actually always passed a org.apache.catalina.connector.RequestFacade to services when asking for javax.servlet.http.HttpServletRequest
in services definition.
Since Tomcat 8.5 RequestFacade implements javax.servlet.http.HttpServletRequest indirectly through
org.apache.catalina.servlet4preview.http.HttpServletRequest
https://tomcat.apache.org/tomcat-8.5-doc/api/org/apache/catalina/connector/RequestFacade.html

Since we have no tests on the payPalCheckoutUpdate service we did not spot that Tomcat servlet4preview was introduced with Tomcat 8.5

The classes check is done by the deeper interfaceOf() method of the ObjectType class using Class.getInterfaces()
https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getInterfaces--
Class.getInterfaces() does not recurse and stops at one level up. So in case of RequestFacade it returns only servlet4preview.http.HttpServletRequest
and not javax.servlet.http.HttpServletRequest
So when interfaceOf() compares the Classes it fails.

What happened with my introduction of the HttpServletRequestWrapper in ContextFilter is it hid the RequestFacade because HttpServletRequestWrapper
implements javax.servlet.http.HttpServletRequest
https://docs.oracle.com/javaee/7/api/javax/servlet/http/HttpServletRequest.html

So when James introduced Tomcat SSO and optionally passed a javax.servlet.http.HttpServletRequest to the userLogin service it did not break.
But when I removed HttpServletRequestWrapper from ContextFilter it popped up

Summary: it's unfortunate because we have no tests on the payPalCheckoutUpdate service.
Because I temporarily introduced HttpServletRequestWrapper James was able to pass a javax.servlet.http.HttpServletRequest, like in payPalCheckoutUpdate.
When I reverted (removed HttpServletRequestWrapper  from ContextFilter) I discovered that we had a problem with Tomcat 8.5.

I propose this fix which uses org.apache.commons.lang3.ClassUtils.getAllInterfaces() and works
http://commons.apache.org/proper/commons-lang/javadocs/api-release/src-html/org/apache/commons/lang3/ClassUtils.html

[Scott Gray-3]

So to summarize your long email ;-)

"The service engine has a limitation in that it only checks the interfaces
directly implemented by the object being tested.  Tomcat's RequestFacade
doesn't directly implement javax.servlet.http.HttpServletRequest so it
fails to pass the type validation."

On the surface your suggested fix looks fine to me, my only concern being
that we may need to do some performance testing.  For every service that
specifies an interface we'll now be checking the full type hierarchy which
I imagine will be more expensive but I'm not sure how expensive.

I'm also not even sure if our custom ObjectType methods for checking this
type of thing are necessary any more with so many new java versions since
it was decided these were needed for performance reasons.

Scott

[Paul Foxworthy]

Hi all,

The servlet4preview package in Tomcat 8.5 "provides early access to some of
the features of Servlet 4.0" (
https://tomcat.apache.org/tomcat-8.5-doc/api/org/apache/catalina/servlet4preview/package-summary.html
).

Does use of this package make OFBiz dependent on a preview version, and if
so is that a good idea? Should features that use some preview (like support
for Tomcat SSO, it appears) be contained in a branch or plugin until the
API has been stabilised?

Tomcat 9 was released in January, with support for Servlet 4.0. If we now
say OFBiz requires Servlet 4.0 and move to Tomcat 9, could we then use the
standard HttpServletRequest?

Thanks

Paul Foxworthy

Another option if we don't want to have to care about this service engine
limitation right now is the type-validation child element of attribute.

Just specify a class/method that takes the HttpServletRequest as an Object
parameter and then perform the "getAllInterfaces()" test inside there.
e.g.
UtilValidate.isHttpServletRequest(Object request) {
  // do the new test here
}

In the service definition:
<attribute name="request" mode="IN"
type="javax.servlet.http.HttpServletRequest"
optional="true">
  <type-validate class="org.apache.ofbiz.base.util.UtilValidate"
method="isHttpServletRequest"/>
</attribute>

That would solve the problem for now until the service engine is improved
and tested or the tomcat SSO login design is improved.

Regards
Scott

[Michael Brohl-3]

Hi Paul,

I agree, that's what I tried to express in my comments on
https://issues.apache.org/jira/browse/OFBIZ-10047:

"7. Someone should check this solution from an architectural view. I
appreciate the efforts but I am also in doubt if we should put this
feature into the new release. It's very fresh, deals with a very central
functionality and should be field tested more."

I really do think that we should have another process when we introduce
this kind of new  functionality, make use of new third party API etc..

You and Scott made valuable points in this discussion and if we would
have had some kind of voting for this, they might be brought up earlier.
The Jira discussions just slip through if there is no discussion on the
dev list.

Thanks,

Michael

What makes you think that Tomcat SSO depends on servlet4preview?
In the the analysis I did for https://issues.apache.org/jira/browse/OFBIZ-10304 I only found that using Tomcat 8.5 (hence servlet4preview) we no
longer can pass a standard HttpServletRequest  or HttpServletResponse with current code.
Did you find something else?

> Tomcat 9 was released in January, with support for Servlet 4.0. If we now
> say OFBiz requires Servlet 4.0 and move to Tomcat 9, could we then use the
> standard HttpServletRequest?
Yes, that would remove the problem and is IMO the best solution.

But after upgrading to Tomcat 8.5 at https://issues.apache.org/jira/browse/OFBIZ-9813 (we did not notice the possible issue with servlet4preview, I
must say it's not obvious in Tomcat 8.5 changelog: no warning) Michael tried to update to Tomcat 9 twice w/o  success:

  * https://issues.apache.org/jira/browse/OFBIZ-10026
  * https://issues.apache.org/jira/browse/OFBIZ-10036


So, I think we need now to continue the work initiated by Michael to definitely close the related dependent issues (by using Tomcat 9):

  * OFBIZ-10304 that made the problem to appear. Actually it was already existing for all services which were using standard HttpServletRequest  or
    HttpServletResponse as IN or OUT or IN/OUT attributes. Not much OOTB, but we don't know for users... Note that with OFBIZ-9813 R17.12 uses Tomcat
    8.5. So it's not only trunk and we need to consider this a bug and update R17.12 as well.
  * https://issues.apache.org/jira/browse/OFBIZ-10047 which IMO does not depend on Tomcat 8.5 but made me research and open OFBIZ-10304 after I could
    not revert the HttpServletRequestWrapper at http://svn.apache.org/viewvc?view=revision&revision=1827441
  * https://issues.apache.org/jira/browse/OFBIZ-10307 were I need to revert my previous work committed for
    https://issues.apache.org/jira/browse/OFBIZ-9833 which was partially wrong.

I purposely put the 1st appearance of a link inside the text. I think it's the easiest way to follow a thought put in an email.

We would need some profiling before making any decision, don't you think so?

[Jacques Le Roux]

That's indeed another option, but I'd prefer to update to Tomcat 9, to definitely get ride of servlet4preview and problems it brings

Michael,

AFAIK, Tomcat SSO does not directly relates to this issue. For me it was just a catalyseur which allowed me to find the servlet4preview issue due to
Tomcat 8.5 usage. And I can say it was not easy.

This said all reviews of https://issues.apache.org/jira/browse/OFBIZ-10047 are welcome. I agree we must be more careful about discussing things in dev
ML before putting in important new feature. This is something we agree about long ago, but tend to forget.

Like people asking user questions on dev ML (w/o not even being subscribed to this ML :/ OK I needed this rant). So yes, we need to continue to
educate ourselves and our users, for the good of the community, and it's not always easy.

Jacques
