[Bug 54262] New: absolute-ordering

https://issues.apache.org/bugzilla/show_bug.cgi?id=54262

            Bug ID: 54262
           Summary: absolute-ordering
           Product: Tomcat 7
           Version: 7.0.33
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: rstoyanchev@yahoo.com
    Classification: Unclassified

The use of an <absolute-ordering> element does disable
ServletContainerInitializer classpath scanning as discussed also in issue
53619. However, it does seem to require having at least one web-fragment name
to be listed. In other words I would this:

<absolute-ordering />

To turn off all web-fragments since none are named. A workaround is to list a
web-fragment even if it doesn't exist but that shouldn't be necessary.

[Bug 54262] An empty should turn off all web-fragments

And what about {tomcat.dist}/lib dir? Because those services are loaded anyway.

Debugging and watching the code of "WebappServiceLoader" and a google search
with "containerSciFilter", I see that I can use a Pattern to exclude that
classes. Is the only way?

Thanks.

resources1.jar

Confirming.

Steps to reproduce with 7.0.34:
1. Download attached resources1.jar and put it into
webapps/examples/WEB-INF/lib

The file is based on test/webapp-3.0-fragments/WEB-INF/lib/resources.jar from
Tomcat sources. I
a) removed all resources except "resourceA.jsp" and
b) declared an instance of HelloWorldServlet in web-fragment.xml.

2. Edit webapps/examples/WEB-INF/web.xml:
a) change metadata-complete attribute s/true/false/
b) add <absolute-ordering />

3. Start Tomcat.
4. Actual result: The following two URLs work:
[1] http://localhost:8080/examples/resourceA.jsp
[2] http://localhost:8080/examples/resources1/HelloWorldExample

Expected result: [2] should return 404 as web-fragment.xml should be ignored
and the servlet mapping declared there should be ignored.

<quote from="Servet Spec 3.0 Rev a - page #67 (89/230)">
1.d. (..) If the
 <absolute-ordering> element does not contain an <others/> element,
 any web-fragment not specifically mentioned within <name /> elements
 MUST be ignored. (...)
</quote>

Regarding [1], I do not see any specific reference that such exclusion affects
static resources in META-INF/resources. Thus I think that the expected
behaviour of [1] is to display resourcesA.jsp page. 7.0.34 behaves correctly
here.
