v2.2.9

What's Changed

• Update codes.go by @helderjnpinto in #214 and #215
• Expire session if SessionExpiryInterval is 0 by @thedevop in #216
  • Corrects an issue where SessionExpiryInterval was not correctly honoured if the value is absent.
• Add packet ID exhausted hook by @mochi-co in #217
  • Corrects an issue where the hook had not been added to the code 😊
• Use context to signal client open state by @mochi-co in #218
  • Replaces the client.State.done atomic int with a context which can be cancelled, for better concurrency in #202
• Refactor server keepalive for hook access by @mochi-co in #220
  • Refactors the implementation of Server Keep Alive. Previously, the server keep alive value was used if the client keepalive value was 0, however this was incorrect. The server keep alive value override has been removed, and is now set if necessary using the OnConnect hook. See examples/paho.testing/main.go for an example.

• Add OnPacketIDExhausted hook by @mochi-co in #211 per #201
• Add lock to client writes by @mochi-co in #212
  • Fixes an issue in which writes could be written in a concurrency unsafe manner (#196)
• Lock on close outbound by @mochi-co in #213
  • Fixes an issue in which writes could continue to be written to the outbound channel after the channel was closed (#202)

• Simplified code by @wind-c in #195
  • Adds a convenient ToPacket method on storage.Message
• #78 storage hook should not execute the relevant code if the client has been reconnected by @werbenhu in #198

v2.2.6

What's Changed

• Common subscriptions issued by different clients at the same time may be lost by @ffa500 in #186
  • Uses additional locks within topics to resolves an issue in which subscriptions could be lost due to concurrent writes.
• Configurable client bufio reader/writer sizes by @mochi-co in #190

Addresses #189 by making the client bufio.Reader and bufio.Writer sizes configurable as server options. The new default value for the reader and writer buffers is 2048. Different values can be configured as such:

server := mqtt.New(&mqtt.Options{
    ClientNetWriteBufferSize: 1024,
    ClientNetReadBufferSize: 1024,
})
