-Assorted TODO notes:
-
-General:
- Protect trace_msg from SIGPIPE?
- prepare(...,{ Err=>\my $isolated_err, ...})
- Add trace modules that just records the last N trace messages into an array
- and prepends them to any error message.
- 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
-
-Gofer TODOs:
-
-Add server-side caching.
- combine these:
- my $request = $transport->thaw_request( $frozen_request, $serializer );
- my $response = $executor->execute_request( $request );
- my $frozen_response = $transport->freeze_response($response,
$serializer);
- into single method that first checks the cache and updates it if
appropriate.
- Different serializations will have different caches
-
-Add DBI::Gofer::Serialiser::MIME / Base64
-Add DBI::Gofer::Serialiser::JSON
-
-Gofer - allow dbh attrib changes after connect?
- note them and pass in request as STORE method calls
- but then gofer server need to reset them to restore dbh to original state
- Or, change the attr in the connect() call, but that risks
- bloating the number of cache dbh in the server.
-Gofer request flags for:
- - return current executor stats as an attribute - handy for tests
- - will accept streamed resultsets
-Add attr-passthru to prepare()? ie for gofer cache control & ReadOnly
-Define and document terminology for client and server ends
-Document user/passwd issues at the various levels of the gofer stack
- Remove "Password" from connect attr if the same as $password arg
-Extract policy settings by parsing the pod
-Policy for dbh attr FETCH (ie example_driver_path)
- or piggyback on skip_connect_check
- could also remember which attr have been returned to us
- so not bother FETCHing them (unless pedantic)
-Call method on transport failure so transport can cleanup/reset if it wants
-Gofer: gearman - need to disable coallesing for non-idempotent requests
-
-Add high-res time for windows - via Time::HiRes glob replace dbi_time().
-

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.
