Convert to async MIB instrumentation API (#210)
MIB instrumentation API changed to allow for asynchronous
managed objects access. The MIB instrumentation methods
called by the state machine now return immediately and
resume once the callback is called.
The built-in SNMPv2-SMI objects are still synchronous.
This change is a prerequisite for fully asynchronous managed objects
implementation.
MIB instrumentation API changed to allow for asynchronous
managed objects access. Although built-in SNMPv2-SMI objects
are still synchronous, the MIB instrumentation API is async
what allows users to replace default MIB instrumentation
with their own, potentially asynchronous.
CommandResponder refactored to facilitate asynchronous
MIB instrumentation routines. The `readVars`, `readNextVars`
and `writeVars` MIB controller methods return immediately and
deliver their results via a call back.
SMI/MIB managed objects API overhauled for simplicity and
flexibility breaking backward compatibility.
* Add `hlapi.v1arch` API
Introduce new sub-package `pysnmp.hlapi.v1arch` which
wraps otherwise very detailed packet-level SNMP
messaging into a handful of convenience functions.
As a side effect, the `pysnmp.hlapi.*` sub-packages
moved under `pysnmp.hlapi.v3arch` though `pysnmp.hlapi`
still exposes `pysnmp.hlappi.v3arch.*` symbols to
retain some degree of backward compatibility.
The signature of the hlapi `.sendNotification()` call
has changed to accept `*varBinds` instead of a sequence
of `varBinds`. The rationale is to unify this method
call with similar methods of CommandGenerator.
* Add v1arch docs and reshuffle hlapi docs
Overhaul SMI/MIB instrumentation API
SMI/MIB managed objects API overhauled for simplicity and
flexibility breaking backward compatibility.
This change would allow way more control over custom MIB
managed objects and also is the prerequisite for
asynchronous MIB instrumentation.
* Asyncio and Twisted API moved entirely into high-level domain to
be aligned with other high-level APIs. This WILL BREAK backward
compatibility for those apps that use Twisted API.
