Bug #: 51912
Summary: Failures in
org.apache.coyote.http11.TestInternalInputBuffer with
NIO + debug logging
Product: Tomcat 7
Version: trunk
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: dev@tomcat.apache.org
ReportedBy: knst.koli...@gmail.com
Classification: Unclassified
I encountered the following while testing 7.0.22 RC.
To reproduce:
1. Replace conf/logging.properties with the following:
===============
handlers = 1catalina.org.apache.juli.FileHandler
.handlers = 1catalina.org.apache.juli.FileHandler
1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.
1catalina.org.apache.juli.FileHandler.bufferSize=20000
.level=FINE
===============
Note that level=FINE enables debug logging.
2. Run testsuite for NIO + org.apache.coyote.http11.TestInternalInputBuffer
by adding the following to build.properties:
execute.test.bio=false
execute.test.nio=true
execute.test.apr=false
test.entry=org.apache.coyote.http11.TestInternalInputBuffer
3. The test fails:
==============
Testsuite: org.apache.coyote.http11.TestInternalInputBuffer
Tests run: 7, Failures: 2, Errors: 0, Time elapsed: 50,357 sec
Testcase: testBug48839 took 9,594 sec
Testcase: testBug51557NoColon took 1,217 sec
FAILED

Testcase: testBug51557Separators took 22,807 sec
Testcase: testBug51557Ctl took 13,104 sec

Testcase: testBug51557Continuation took 1,248 sec
Testcase: testBug51557BoundaryStart took 1,185 sec
Testcase: testBug51557BoundaryEnd took 1,186 sec
==============
4. It is the only test in testsuite that is failing in this logging
configuration. The rest of testsuite did run successfully.
This test also succeeds when it is run with BIO or APR. Only NIO fails.
In the log file the following exception occurs 3 times:
==============
28.09.2011 17:50:38 org.apache.coyote.http11.AbstractHttp11Processor process
FINE: Error parsing HTTP request header
java.lang.StringIndexOutOfBoundsException: String index out of range: -40

at
java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
at java.lang.Thread.run(Thread.java:662)
==============
It is caused by debug logging in
org.apache.coyote.http11.InternalNioInputBuffer.skipLine(InternalNioInputBuffer.java:672)
671 if (log.isDebugEnabled()) {
672 log.debug(sm.getString("iib.invalidheader", new String(buf,
673 headerData.start,
674 headerData.lastSignificantChar - headerData.start + 1,
675 DEFAULT_CHARSET)));
676 }
InternalInputBuffer and InternalAprInputBuffer have similar debug logging in
their skipLine() methods, but they do not fail.
