Fix db exhaustion - 1.7.x #7745

heifner · 2019-08-09T18:47:53Z

Change Description

nodeos_under_min_avail_ram_lr_test periodically fails because we are not properly handling database_guard_exception in all places.
Add additional catch clauses for database_guard_exception via new catch macro in producer_plugin.
Also address std::bad_alloc in controller emit as mentioned in Several locations swallow std::bad_alloc #6979
fc exceptions still do not correctly handle std::bad_alloc. A different PR to fc repo needs to be created to address that.
