The Apache Tomcat Native - Miscellaneous Documentation

This is the Changelog for Tomcat Native. This changelog does not contain all updates and fixes to the Tomcat Native (yet). It should contain fixes made only after December 19th 2007, when the new documentation project for Tomcat Native was started.

• Unconditionally disable export Ciphers. Use the configure flag --enable-insecure-export-ciphers for a custom build supporting those insecure ciphers. (rjung)
• Improve ephemeral key handling for DH and ECDH. Parameter strength is by default derived from the certificate key strength. It can be overwritten by embedding custom parameters in the certificate file configured with SSLCertificateFile. (rjung)
• The APIs SSL.generateRSATempKey() and SSL.loadDSATempKey() are no longer supported. (rjung)
• Require minimum version 0.9.8m of OpenSSL. (rjung)
• Use APR pool pre-cleanup API if available to reduce possibility of JVM core on shutdown. (mturk, rjung)
• Add feature check for APR pre-cleanup API. (mturk, rjung)
• Don't destroy pools explicitly if we are inside an apr_terminate call. (mturk, rjung)
• Fix a small memory leak if Socket.recv() is used with big buffers and recv() gets an error. (costin, rjung)
• Pass back error to JVM if a threadsafe poller should be created but the underlying APR library was build without thread support. (costin, rjung)
• Fix compilation failures with master branch of OpenSSL. Replace access to OpenSSL internals by accessor functions. (billbarker, rjung)
• Let OpenSSL master handle thread IDs itself. (billbarker)
• Minor rework of "buildconf" script. (rjung)
• Fix APR dependency version expression and requirement expression in RPM spec file. (rjung)
• Try to make the changelog.xml served by SVN-HTTP viewable in a browser by adding a stylesheet reference. (kpreisser, rjung)
• Remove code that performs a read after a renegotiation that appears to be unnecessary with OpenSSL 1.0.2. (billbarker)

• Fix compilation failures with master branch of OpenSSL. Replace access to OpenSSL internals by accessor functions. (rjung/kkolinko)
• Fix a zero-boundary-check compiler warning and simplify code in the process. (rjung)

• Change return code when removing a socket from a poller, that was actually not in the poller from APR_SUCCESS to APR_NOTFOUND. (rjung)

• Java classes in package org.apache.tomcat.jni are now taken from Tomcat trunk using svn:externals. (rjung)
• Minimum supported APR version is now again 1.2.1. Version 1.3.0 of APR improves performance. (rjung)
