GitHub issue: #539.

Contributed by Carl Hörberg.

GitHub issue: #534.

Contributed by Andrew Babichev.

Changes between Bunny 2.7.0 and 2.8.0 (Dec 18th, 2018)

This release has minor breaking public API changes.

Bunny::Channel#close on a Closed Channel Now Raises a Sensible Exception

Bunny::Channel#close on an already closed channel will now raise a sensible exception. If the channel was closed due to a channel-level protocol exception, that exception will be mentioned.

GitHub issue: #528, see 9df7cb for details.

JRuby 9K Compatibility

A JRuby 9K compatibility issue was corrected by Marian Posăceanu. Note that JRuby users are recommended to use March Hare, a JRuby-oriented client, instead of Bunny.

GitHub issue: #529

Connection Exceptions are Logged as Warning with Automatic Recovery

When automatic recovery is enabled, connection errors are now logged as warnings and not errors.

Contributed by Merten Falk.

GitHub issue: #531

Server Heartbeat Value as a String

It is now possible to specify a server-defined heartbeat value as a string ("server"), not just a symbol. This makes it easier to load settings from YAML files.

Contributed by Tyrone Wilson.

GitHub issue: #524

Changes between Bunny 2.7.0 and 2.7.1 (Sep 25th, 2017)

Sensible Socket Read Timeouts When RabbitMQ is Configured to Disabled Heartbeats

Bunny now correctly handles scenarios where server is configured to disable heartbeats (which is a terrible idea, don’t do it!)

GitHub issue: #519.

Bunny::Channel#basic_get Usability

Bunny::Channel#basic_get invoked with a non-existent queue now throws a channel exception instead of a generic operation timeout.

GitHub issue: #518.

Spec Suite Improvements

BUNNY_CERTIFICATE_DIR environment variable now can be used to override local CA and client certificate/key pair directory. The directory is expected to be the result directory generated by the basic tls-gen profile.

TLSv1.0 is no longer used in tests because it’s being disabled by default by more and more installations as it has known vulnerabilities and is no longer considered to be acceptable by several compliance standards (e.g. PCI DSS).

Improved Synchronisation for channel.close Handlers

channel.close handler will now acquire a lock . This avoids concurrency hazards in some rare scenarios when a channel is closed due a protocol exception by the server and concurrently opened by user code at the same time.

More Meaningful Error Messages in Bunny::Session#create_channel

Sometimes users attempt to open a channel on a connection that isn’t connected yet because Bunny::Session#start was never invoked.

Bunny::Session#create_channel will now provide a more sensible exception message in those cases.
