+   * mod_dbd: Rename functions and variables for consistency, and move
+     some functions around for readability, prior to making
+     functional changes for PRs 39985, 41302, and other issues.
+     Trunk version of patches:
+       http://svn.apache.org/viewvc?view=rev&revision=491729
+       http://svn.apache.org/viewvc?view=rev&revision=492394
+         (relevant portions only)
+       http://svn.apache.org/viewvc?view=rev&revision=521230
+     2.2.x version of patch:

+     +1: chrisd
+
+   * mod_dbd: Handle error conditions in dbd_construct() properly.
+     Simplify ap_dbd_open() and use correct arguments to apr_dbd_error()
+     when non-threaded.  Register correct cleanup data in non-threaded
+     ap_dbd_acquire() and ap_dbd_cacquire().  Clean up configuration data
+     and merge function.  Use ap_log_error() wherever possible.

+     +1: chrisd
+
+   * beos MPM: Create pmain pool and run modules' child_init hooks when
+     entering ap_mpm_run(), then destroy pmain when exiting ap_mpm_run().
+     Otherwise modules' child_init hooks appear to never be executed.
+     Also, destroying pmain ensures that cleanups registered in modules'
+     child_init hooks are performed (e.g., mod_log_config and mod_dbd).

+       http://svn.apache.org/viewvc?view=rev&revision=491922

+     +0: chrisd (abstaining; unable to test)
+
+   * netware MPM: Destroy pmain pool when exiting ap_mpm_run() so that
+     cleanups registered in modules' child_init hooks are performed (e.g.,
+     mod_log_config and mod_dbd).
+     Trunk version of patch:

+     +0: chrisd (abstaining; unable to test)
+
+   * mod_dbd: Create memory sub-pools for each DB connection and close
+     DB connections in a pool cleanup function.  Ensure prepared statements
+     are destroyed before DB connection is closed.  When using reslists,
+     prevent segfaults when child processes exit, and stop memory leakage
+     of ap_dbd_t structures.  Avoid use of global s->process->pool, which
+     isn't destroyed by exiting child processes in most multi-process MPMs.
+     See also the third section of:
+       http://marc.info/?l=apache-httpd-dev&m=116742014418304&w=2

+     dbd_setup() function.

+     +1: chrisd
+
+   * mod_dbd: Introduce configuration groups to allow inheritance by virtual
+     hosts of database configurations from the main server.  Determine the
+     minimal set of distinct configurations and share connection pools
+     whenever possible.  Allow virtual hosts to override inherited SQL
+     statements.  See also the fourth section of:
+       http://marc.info/?l=apache-httpd-dev&m=116742014418304&w=2
+     and the eventual solution as implemented in the dbd_post_config()
+     function.  Obviates r424798, r432560, r432562, and r466641.
+     Could be improved by the addition of <DBDGroup> configuration
+     sections.  (Any takers?  :-)
