NoMethodError: undefined method `call' for Mongo::WriteConcern::Unacknowledged

[zarqman]

Hi there. Today I tried to upgrade an existing app to the latest versions of mongo-ruby and mongo_ha. This resulted in numerous NoMethodError exceptions, like the one shown below.

Generates errors:

• mongo_ha 2.5.0
• mongo 2.5.1
• bson 4.3.0
• ruby 2.4.3

Prior versions that ran successfully:

• mongo_ha 2.4.2/0dc9055
• mongo 2.4.3
• bson 4.2.2

Let me know if there's anything I can do to help debug/test the issue.

It appears that between the mongo ruby driver 2.5.0 and 2.5.1 there were significant changes, including support for Mongo Sessions.

For now using mongo 2.5.0 will work. Researching how to fix the patching code to work with mongo 2.5.1

Published mongo_ha gem version 2.5.1 that is compatible with mongoldb Ruby driver v2.5.1
