D. Changes from Version (3.1.4)

New Features

New apache.register_cleanup() method.
New apache.exists_config_define() method.
New file-based session manager class.
Session cookie name can be specified.
The maximum number of mutexes mod_python uses for session locking can now be specifed at compile time using configure --with-max-locks.
New a version attribute in mod_python module.
New test handler testhandler.py has been added.

Improvements

Autoreload of a module using apache.import_module() now works if modification time for the module is different from the file. Previously, the module was only reloaded if the the modification time of the file was more recent. This allows for a more graceful reload if a file with an older modification time needs to be restored from backup.
Fixed the publisher traversal security issue
Objects hierarchy a la CherryPy can now be published.
mod_python.c now logs reason for a 500 error
Calls to PyErr_Print in mod_python.c are now followed by fflush()
Using an empty value with PythonOption will unset a PythonOption key.
req.path_info is now a read/write member.
Improvements to FieldStorage allow uploading of large files. Uploaded files are now streamed to disk, not to memory.
Path to flex is now discovered at configuration time or can be specifed using configure --with-flex=/path/to/flex.
sys.argv is now initialized to ["mod_python"] so that modules like numarray and pychart can work properly.

Bug Fixes

Fixed memory leak which resulted from circular references starting from the request object.
Fixed memory leak resulting from multiple PythonOption directives.
Fixed Multiple/redundant interpreter creation problem.
Cookie attributes with attribute names prefixed with $ are now ignored. See Section 4.7 for more information.
Bug in setting up of config_dir from Handler directives fixed.
mod_python.publisher will now support modules with the same name but in different directories
Fixed continual reloading of modules problem
Fixed big marshalled cookies error.
Fixed mod_python.publisher extension handling
mod_python.publisher default index file traversal
mod_python.publisher loading wrong module and giving no warning/error
apply_fs_data() now works with "new style" objects
File descriptor fd closed after ap_send_fd() in req_sendfile()
Bug in mem_cleanup in MemorySession fixed.
Fixed bug in _apache._global_lock() which could cause a segfault if the lock index parameter is greater number of mutexes created at mod_python startup.
Fixed bug where local_ip and local_host in connection object were returning remote_ip and remote_host instead
Fixed install_dso Makefile rule so it only installs the dso, not the python files
Potential deadlock in psp cache handling fixed
Fixed bug where sessions are used outside <Directory> directive.
Fixed compile problem on IRIX. ln -s requires both TARGET and LINK_NAME on IRIX. ie. ln -s TARGET LINK_NAME
Fixed ./configure problem on SuSE Linux 9.2 (x86-64). Python libraries are in lib64/ for this platform.
Fixed req.sendfile() problem where sendfile(filename) sends the incorrect number of bytes when filename is a symlink.
Fixed problem where util.FieldStorage was not correctly checking the mime types of POSTed entities
Fixed conn.local_addr and conn.remote_addr for a better IPv6 support.
Fixed psp_parser.l to properly escape backslash-n, backslash-t and backslash-r character sequences.
Fixed segfault bug when accessing some request object members (allowed_methods, allowed_xmethods, content_languages) and some server object members (names, wild_names).
Fixed request.add_handler() segfault bug when adding a handler to an empty handler list.
Fixed PythonAutoReload directive so that AutoReload can be turned off.
Fixed connection object read() bug on FreeBSD.
Fixed potential buffer corruption bug in connection object read().
