Call to undefined function _drush_sql_get_db_spec() [#2448147]

I installed cache warmer per the fairly straight forward instructions on the project page. I also created the hub pages text file in ~/.drush/ but am getting an error when trying to run the command...

drush cache-warmer --updated-last='-24 hours' --timeout=15 --hub-pages-file=~/.drush/hub_pages.txt http://www.example.tld

Cannot open hub pages file ~/.drush/hub_pages.txt.                    [error]
Cannot determine base URI to be crawled.                             [error]

PHP Fatal error:  Call to undefined function _drush_sql_get_db_spec() in /root/.drush/cache_warmer/cache_warmer.drush.inc on line 287

Drush command terminated abnormally due to an unrecoverable error.   [error]

I switched hubpages.txt to be owned by lighttpd (the web server and the php-fpm process owner) after receiving this error, assuming drush couldn't read it for whatever reason, and still get the same error.

I then tried moving the hub_pages.txt file to the local root folder of drupal where I am running the drush command.

drush cache-warmer --latest-n=3000 --hub-pages-file=./hub_pages.txt --timeout=30 http://www.example.tld

PHP Fatal error:  Call to undefined function _drush_sql_get_db_spec() in /root/.drush/cache_warmer/cache_warmer.drush.inc on line 287

Drush command terminated abnormally due to an unrecoverable error.  [error]

Error: Call to undefined function _drush_sql_get_db_spec() in /root/.drush/cache_warmer/cache_warmer.drush.inc, line 287

Am I missing something very obvious?

Update: It appears as though this issue is more specific to Drush versioning. Drush 6.x-stable and below use "_drush_sql_get_db_spec()" which was removed in Drush 7.x. Given that Drush 7.x is required for Drupal 8.x, I would recommend forward compatibility. I found https://www.drupal.org/node/2261469#comment-8757125 which suggests a patch for Drush 7.x but would break Drush 6.x and below. Is there perhaps some logic you could add to check the drush version and execute the proper function?
