   Increase test coverage
       More tests need to be added to test the codes that not urrently being tested.

       It's pretty poor right now:

          http://pjcj.sytes.net/cover/latest/DBI-1.52/coverage.html

       Start with improving the subroutine coverage

          http://pjcj.sytes.net/cover/latest/DBI-1.52/blib-lib-DBI-pm--subroutine.html

   Test the proxy
       The current t/80proxy.t is isolated from the rest of the test suite so actually tests very little, and what it does test is duplicating
       other tests.

       Ideally the proxy should be tested in the same way as DBI::PurePerl.  In other words, by creating wrappers test files for each test file
       that set $ENV{DBI_AUTOPROXY} and run the original test. They'll also need to start and stop a proxy server.

   Fixing bugs
       The official bug list is here:

          http://rt.cpan.org/NoAuth/Bugs.html?Dist=DBI

       Naturally I'll offer direction and guidance on any you want to tackle.  I've also got a few that could be entered into rt.cpan.org.

   Others
       General:

           Protect trace_msg from SIGPIPE?
           prepare(...,{ Err=>my $isolated_err, ...})
           Add trace module that just records the last N trace messages into an array
               and prepends them to any error message to provide context for the error.
           Document DBI_PROFILE_FLOCK and LockFile attrib in DBI::ProfileData and DBI::ProfileDumper

       Performance:

           Move _new_sth to DBI::db::_new_sth (leave alias) and implement in C
               Or call _new_child and move to DBI::common?

           Implement FETCH_many() in C

           Add high-res dbi_time for windows - via Time::HiRes glob replace dbi_time()?

perl v5.12.1                                                        2009-06-08                                                            TASKS(3)
