No, the intent of the language was only to make clear that the
delegation order must be honoured when loading SCI implementations.
To quote from the Servlet EG discussion on this topic:
If the same ServletContainerInitializer is both on the container classpath
and in a jar in WEB-INF/lib, which one should be used?
Will this be by the normal inverted classloading priority
of web applications?
The result of the discussion was "Yes." and the language was added to
the end of 8.2. It went on to discuss some edge cases but no conclusion
was reached and no further clarification was added to the spec.

I'll take another look at r1524727 as that isn't want was intended. What
should happen is:
- List all SCIs defined by the container
- List all SCIs defined by the application (may only be from a subset of
JARs if absolute ordering is present)
- Load all the SCIs defined by the container (note some may be loaded
from the application if the application ships with an alternative
implementation and the application first delegation model is being used)
- Load all the SCIs defined by the application

No. It would still be loaded from the application (for that webapp).

I disagree. The specification uses adding frameworks as an example of a
use case the an SCI can support, but nowhere does it say that it may not
be used by applications or that it isn't intended for applications.

[Bug 55582] New: Concurrent issue of TagFileProcessor
https://issues.apache.org/bugzilla/show_bug.cgi?id=55582
Bug ID: 55582
Summary: Concurrent issue of TagFileProcessor
Product: Tomcat 7
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
Assignee: dev@tomcat.apache.org

Unsynchronized getting wrapper from RuntimeContext
The following code has concurrent issue.
JspRuntimeContext rctxt = ctxt.getRuntimeContext();
JspServletWrapper wrapper = rctxt.getWrapper(wrapperUri);
synchronized (rctxt) {
if (wrapper == null) {
It creates duplicated JspServletWrapper in this scenario,
A.jsp --> C.tag
B.jsp --> C.tag
A.jsp and B.jsp are both compiling and come to the given lines.
Two threads all get null from JspRuntimeContext(JspServletWrapper == null).
So two instances of JspServletWrapper was created.

Issue in AprEndpoint detected by TestCoyoteAdapter

The following patch seems to fix it for me, at least 150 test runs for
TestCoyoteAdapter were successful:

fd.desc_type = APR_POLL_SOCKET;
fd.desc.s = s->sock;
I'll let the full test suite for APR run a couple of times as a more
thorough check. I hope the change doesn't break the correctnes of the
connection counting which is only done after succesful return of remove.

I see only failures in TestCoyoteOutputStream when running the full test
suite for APR, all other tests look OK.
When running TestCoyoteOutputStream alone in a loop it also occasionally
(2/10) fails for bio and nio, for apr somewhat more often (4/10), so the
failure seems unrelated to the poll.c change. Actually there's two types
of failures for TestCoyoteOutputStream, mostly a 300 seconds read
timeout in testNonBlockingWriteNoneBlockingWriteOnce and once for nio
"java.io.IOException: Bogus chunk size" in
testNonBlockingWriteOnceBlockingWriteOnce

For two versions of the *same* implementation, yes. But if they used *different* implementations of the *same functionality,* the container's would always get precedence. For example, if an application included Tyrus's WebSocket implementation it would always be invoked after Tomcat's. Or for JAX-RS, if the container was configured with CXF and the application included Jersey, Jersey would not be able to register its Servlets for the REST endpoints as CXF would have already mapped them. The issue here is that programmatic registrations cannot modify the existing configuration. Once a framework has registered a servlet, filter, listener or mapping it cannot be replaced by another. Frameworks that applications bundle in WEB-INF/lib need to have a chance to perform their initialization before an equivalent but different implementation provided by the container. -- Jeremy signature.asc Description: Message signed with OpenPGP using GPGMail

Re: Issue in AprEndpoint detected by TestCoyoteAdapter

I debugged around my occasional failures for TestCoyoteAdapter when
using APR.
Error is:
SEVERE [http-apr-127.0.0.1-auto-13-Poller]
org.apache.tomcat.util.net.AprEndpoint$Poller.run Poller failed with
error [81] : [File descriptor in bad state]

Not sure whether the problem is more in the concurrent poll plus remove,
or the following code in poll.c:
TCN_IMPLEMENT_CALL(jint, Poll, remove)(TCN_STDARGS, jlong pollset,
jlong socket)
{
apr_pollfd_t fd;
apr_status_t rv;
tcn_pollset_t *p = J2P(pollset, tcn_pollset_t *);
tcn_socket_t *s = J2P(socket, tcn_socket_t *);
UNREFERENCED_STDARGS;
TCN_ASSERT(socket != 0);
if (s->pe == NULL) {
/* Already removed */
return APR_SUCCESS;
}
Here we return APR_SUCCESS and the code calling Poll.remove in
AprEndpoint always does:
rv = Poll.remove(pollers[i], socket);
if (rv != Status.APR_NOTFOUND) {
pollerSpace[i]++;
connectionCount--;
break;
}
So the pollerSpace and connectionCount numbers are (in/de)cremented.
The following patch seems to fix it for me, at least 150 test runs for
TestCoyoteAdapter were successful:
Index: ../native/branches/1.1.x/native/src/poll.c

The patch seems fine. I mean any return value should do in theory.
The main question is why is particular socket removed twice
from the Poller. This is called directly from java code
so wrapper seems to call it twice (or more).
I suspect that the socket is first closed and then Poller loop removes it.
Or it can be removed by poll with doRemove == true or during pollset maintain.
In any case after removed either by poll or maintain returned set of removed
sockets must be invalidated from pollset so it doesn't use it again in explicit
remove.
