Overview:
- One special observation in unit tests: Test
org.apache.catalina.core.TestDefaultInstanceManager throws 3
NullPointerExceptions, that seem to indicate a broken test (see below).
- JMX shows that websocket filter is configured for all default apps.
I didn't check, where this comes from, but should it really be
active by default?
- MBeans "Catalina:context=/...,host=localhost,type=WebResourceRoot"
and
"Catalina:context=/...,host=localhost,name=Cache,type=WebResourceRoot"
very similar in name (same type).
All of the numeric data moved from the first to the second
(plus additional interesting data in the second), in the first it
is only left traceLockedFiles, stateName, cachingAllowed,
traceResources and allowLinking which is all boolean or enum type.
Should we make the two MBeans differ by "type"?
- Same MBean: new attributes traceLockedFiles (boolean) and
traceResources (Array): should the second be named tracedResources
(additional "d") to distinguish the Array list of resources from the
boolean to trace or not to trace switch?
- MD5 OK
- signatures OK
- key in KEYS file
- gz and zip for src and bin consistent
- src consistent with svn tag
- builds fine but
- Very few warnings about unsafe or unchecked operations,
a little less than for RC5.
See full list at end of mail.
- build result looks consistent with binaries
- no checkstyle complaints
- no Javadoc warnings
- No unit test failures, great!
- Warnings a bit lower than RC 5, errors and exception counts during
unit tests higher than for RC 5, mostly in
TestHostConfigAutomaticDeployment.
- JMX MBean-Comparison with RC 5:
- 5 new MBeans
Catalina:context=/...,host=localhost,name=Cache,type=WebResourceRoot
- Old MBeans Catalina:context=/...,host=localhost,type=WebResourceRoot
dropped attributes cacheMaxObjectSize, cacheTtl and cacheMaxSize
moved to the new MBean, attributes objectName and domain completely
removed, attributes traceLockedFiles (boolean) and
traceResources (Array) added.
- ordering of tokens in ObjectName and attributes "objectName",
"children" and "servlets" changed to be more logical
- some filter name changes
- from "org.apache.tomcat.websocket.server.WsFilter" to
"Tomcat WebSocket (JSR356) Filter"
- from "Timing filter" to "Timing Filter" (upper case "f")
- MBean j2eeType=WebModule removed attribute antiJARLocking,
added attribute tldValidation with value false
- MBean ThreadPool added attribute executorTerminationTimeoutMillis
with value 5000
- MBean WebappClassLoader removed attributes jarPath and
antiJARLocking
For the examples webapp also changed order of URLs
(jstl.jar and standard.jar switched position)
- MBean Loader attribute loaderRepositoriesString simple path names
like "/WEB-INF/classes/" changed to file URLs like
"file:/.../output/build/webapps/examples/WEB-INF/classes/".
The same in the loaderRepositories array.
- MBean OperatingSystem attribute OpenFileDescriptorCount up
from 86 to 87
Build and tests were done using Java 1.7.0_45. OS was Solaris 10 Sparc,
tcnative was 1.1.29 based on APR 1.4.8 and OpenSSL 1.0.1e (plus a few
patches).
