CHANGELOG.md

naz changelog:

most recent version is listed first.

version: v0.7.6

version: v0.7.4

• Fix a bug that prevented enquire_link and deliver_sm from been sent: #179
• Enforce naz message protocol in code: #179
• make naz.Client.logger to be a python logging.Handler: #181
• carry out fuzzy testing: #178
• re-run benchmarks: #182

version: v0.7.3

• make naz.SimpleCorrelater.delete_after_ttl() private: #172
• rename naz.broker.BaseOutboundQueue to naz.broker.BaseBroker: #174
  this is the more idiomatic name for what it is.
• re-run benchmarks after renmaing Queue to Broker: #176

version: v0.7.2

• fix infinite loop bug, which could occur while re-establishing connection & re-binding to SMSC: #171

version: v0.7.1

• add ability to start naz even when SMSC is down: #168
  this may be important when you want to deploy naz when the mno/SMSC is down and you want naz to automatically connect when the SMSC comes back online.

version: v0.7.0

• Use python 3.7 since it has better async/await support: #166

version: v0.6.8

• add target level to Breachandler: #163

version: v0.6.7

• make available to hooks the raw pdu as sent/received to/from SMSC: #159
• rename the naz.hooks.BaseHook methods: #159 The new names are more correct and indicate what is actually taking place.
• use github actions for CI: #162
• Add heartbeat to BreachHandler: #161

version: v0.6.6

• make sure that naz reads exactly the first 4bytes of an smpp header: #153
  • if naz is unable to read exactly those bytes, it unbinds and closes the connection
  • this is so as to ensure that naz behaves correctly and does not enter into an inconsistent state.
• make sire that naz reads exacly the first 16bytes of the smpp header: #155
  • this builds on the earlier work but now naz takes it a step further and will unbind & close connection if it is unable to read the entire SMPP header
  • this is done to prevent inconsistency and also to try and be faithful to the smpp spec.
• enhance type annotations of naz.log: #156

version: v0.6.5

• Simplify Breach log handler: #152

version: v0.6.4

• added a logging BreachHandler: #149
• renamed naz.logger to naz.log: #150
• fix documentation styling: #151

version: v0.6.3

• added static analysis support using pytype: #148

version: v0.6.2

• If naz were to encounter an SMPP protocol error, it now bails early by unbinding and closing connection: #147

version: v0.6.1

• all the changes in v0.6.0-beta.1
• fix a number of logging issues: #105
• cleanly handle termination signals like SIGTERM: #106

• added naz benchmarks and related fixes that came from the benchmark runs: #127
  • when smsc returns ESME_RMSGQFUL(message queue is full), naz will now call the throttling handler.
  • fixed a potential memory leak bug in naz.correlater.SimpleCorrelater
  • added a configurable connection_timeout which is the duration that naz will wait, for connection related activities with SMSC, before timing out.
  • naz is now able to re-establish connection and re-bind if the connection between it and SMSC is disconnected.
• renamed connection_timeout to socket_timeout: #141
• added benchmarks results: #141
• updated documentation and moved it to komuw.github.io/naz; #146

version: v0.6.0-beta.1

• Bug fix: #98
  the way naz was handling correlations was:

  • when sending submit_sm we save the sequence_number
  • when we get submit_sm_resp we use its sequence_number and look it up from Correlater
  • when we get a deliver_sm request, we use its sequence_number and look it up from Correlater

  The way naz now does it after the fix is;

  • when sending submit_sm we save the sequence_number
  • when we get submit_sm_resp we lookup sequence_number and use it for correlation
  • Additionally, submit_sm_resp has a message_id in the body. This is the SMSC message ID of the submitted message.
  • We take this message_id and save it.
  • when we get a deliver_sm request, it includes a receipted_message_id in the optional body parameters.
  • we get that receipted_message_id and use it to lookup from where we had saved the one from submit_sm_resp

• This release also features an enhancement(and better tests) of correlation: #98

version: v0.5.0-beta.1

• Start tracking changes in a changelog
• Add more type hints and also run mypy across the entire repo: #92
• It's now possible to bring your own logger: #93
• Made the various interfaces in naz to inherit from abc.ABC: #95
• Fixed a few stylistic issues raised by codacy: #96
