+1 as an alpha and congrats!

Overview:

- one crash in tcnative during unit tests
- MBeans indicate common loader is gone (is that expected?
  At least the common.loader entry still exists in catalina.properties)
- some MBean data gone (resource cache statistics, environment content)
- Catalina:j2eeType=WebModule,name=//localhost attribute
  workDir switched from work/Catalina/localhost/_
  to work/Catalina/localhost/ROOT
- new SEVERE and Exceptions in unit test output, maybe expected
- bayeaux and tomcat-lite modules not bundled


- MD5 OK
- signatures OK
- key in KEYS file
- gz and zip for src and bin consistent
! src consistent with svn tag except:
  - modules bayeux and tomcat-lite not in src
  - file
res/META-INF/tomcat-websocket.jar/services/javax.servlet.ServletContainerInitializer
    has Unix line ends in svn, but the src archives
    for Unix and Windows both contain it with DOS line ends
! builds fine but
  - several warning about unsafe or unchecked operations.
    See full list at end of mail.
- build result looks consistent with binaries
- no checkstyle complaints
- only few Javadoc warnings, I fixed those
! Unit tests few failures and errors:

  - Timing: TestWebSocketFrameClient.testConnectToServerEndpointSSL()
    took 63-66 seconds, but expects only 60 seconds.


  - On NIO in addition (same test):

java.lang.NullPointerException

  - On APR in addition a crash (core) in:

The reason for the crash is likely:

So dereferencing it in (*s->net->recv) gives a segfault.

- JMX MBean-Comparison with TC 7:

  - MBean Catalina:type=ServerClassLoader,name=common no longer exists
  - MBeans j2eeType=WebModule attribute
    parentClassLoader is no longer of type
    org.apache.catalina.loader.StandardClassLoader
    but instead java.net.URLClassLoader
  - MBeans j2eeType=Servlet and j2eeType=WebModule no longer
    have attributes eventProvider and statisticsProvider
  - MBeans j2eeType=WebModule no longer have attributes
    saveConfig, staticResources and mappingObject
  - MBeans type=Cache replaced by type=WebResourceRoot
    - old attributes accessCount, hitsCount, desiredEntryAccessRatio,
      cacheSize, maxAllocateIterations removed
    - new attributes cacheMaxObjectSize, cacheTtl, cachingAllowed,
      allowLinking, stateName, objectName, domain added

    repositoriesString and searchExternalFirst.
    Probably replaced by the new Resources impl.
  - MBeans type=WebappClassLoader no longer has attribute
    searchExternalFirst.
    Probably replaced by the new Resources impl.
  - ThreadPool, RequestProcessor and GlobalRequestProcessor now
    for nio instead of bio as default; corresponding name changes
    in thread names, class names etc. and increased maxConnections
  - nio based ThreadPools switch useComet, usePolling and
    useCometTimeout from "false" to "true", for http also
    useSendfile switched from "false" to "true".
    New attributes keepAliveCount, pollerThreadCount,
    pollerThreadPriority, selectorTimeout, selectorPool and
    oomParachute

    localhost_access_log. to localhost_access_log (prefix and
    fileDateFormat changes OK), resolveHosts attribute gone (unused),
    info attribute gone (not a big loss)
  - Catalina:type=Valve,host=localhost,name=ErrorReportValve
    attribute info gone (not a big loss)
  - Catalina:type=Engine attribute baseDir replaced by catalinaBase
  - Catalina:j2eeType=WebModule,name=//localhost attribute
    ignoreAnnotations switched from "true" to "false",
    attribute workDir switched from work/Catalina/localhost/_
    to work/Catalina/localhost/ROOT

    *.jarsToSkip replaced by t.u.s.StandardJarScanFilter.jarsToScan and
    t.u.s.StandardJarScanFilter.jarsToSkip



Build and tests were done using Java 1.7.0_25. OS was Solaris 10 Sparc,
tcnative was 1.1.27 based on APR 1.4.8 and OpenSSL 1.0.1e (plus a few
patches).

Unit test warnings (very similar to 7.0.35 and before, but two new ones,
one NPE in access log, one testResources warning):

- org.apache.tomcat.util.descriptor.web.TestWebXmlOrdering
  - (old) BIO, NIO and APR: [main]
    org.apache.tomcat.util.descriptor.web.WebXml.orderWebFragments
    Used a wrong fragment name z at web.xml absolute-ordering tag!
  - (new) BIO, NIO and APR: [main]
    org.apache.tomcat.util.descriptor.web.WebXml.setVersion
    Unknown version string [0.0]. Default version will be used.

- org.apache.tomcat.util.net.TestCustomSsl
  - (old) BIO twice "Exception getting SSL attributes"
    in org.apache.coyote.http11.Http11Processor actionInternal
    exception is:
    javax.net.ssl.SSLProtocolException: handshake alert: no_certificate
  - (old) NIO twice "Exception re-negotiating SSL connection"
    in org.apache.coyote.http11.Http11NioProcessor actionInternal

- org.apache.catalina.startup.TestHostConfigAutomaticDeployment
  - (new) BIO, NIO and APR: [main] 3 times each
    org.apache.catalina.startup.HostConfig deployDescriptor
    A docBase .../webapps/myapp inside the host appBase has been
    specified, and will be ignored
  - (new) BIO, NIO and APR: [main] 2 times each
    org.apache.catalina.startup.HostConfig deployWARs
    The directory [.../webapps/myapp] will be ignored because the WAR
    [.../webapps/myapp.war] takes priority and unpackWARs is false

- tribes: several warnings (41), numbers up by 22 from 7.0.42.
  Mostly same types of messages.

Unit test SEVERE messages: 439 total (+218 rel TC 7).

About 200 of those are of types not observed for TC 7:

The rest looks very similar to TC 7:

Most of those are of type "Servlet.service() for servlet ... threw
exception" (137 times, unchanged).

Second biggest block (unchanged):

Count    message
  27     [junit] TIMESTAMP SEVERE [main]
org.apache.tomcat.util.digester.Digester.startElement Begin event threw
exception
   3     [junit] TIMESTAMP SEVERE [main]
org.apache.tomcat.util.digester.Digester.endElement End event threw
exception

Third biggest block is 15 (-4) messages from the mem leak detection
during context unload (same types as before), but in addition one new
message

The web application [] is still processing a request that has yet to
finish. This is very likely to create a memory leak. You can control the
time allowed for requests to finish by using the unloadDelay attribute
of the standard Context implementation.

in org.apache.catalina.connector.TestMaxConnections for BIO, NIO, APR 2
times each.


"Exception" in output of unit tests: 475 times (+256 rel. TC 7).

Top exception counts (some new entries):

I'm not claiming that any of the SEVERE or Exception messages are
important.
