# Rails has a circular dependency in SchemaCache.
|
||
|
|
# In certain situation SchemaCache can carry a @connection
|
||
|
|
# from a different thread. This causes potential concurrency bugs
|
||
|
|
# in Sidekiq.
|
||
|
|
#
|
||
|
|
# This patches it so it is less flexible (theoretically) but always bound to the current connection
|
||
|
|
|
||
|
|
# This patch needs to be reviewed in future versions of Rails.
|
||
|
|
# We should consider upstreaming this optionally.
