* Bug #610: Decorate models appropriately when `HierarchicalMachine`
is passed to `add_state` (thanks @e0lithic)
* Bug #647: Let `may_<trigger>` check all parallel states in processing
order (thanks @spearsear)
* Bug: `HSM.is_state` works with parallel states now
* Experimental features:
+ Add `model_override` to Machine constructor to determine the mode of
operation. With `model_override=Fale` (default), `transitions` will
not override already defined methods on a model just as it did before.
For workflows relying on typing, `model_override=True` will override
methods already defined on the model and only those (!). This allows
to control which convenience methods shall be assigned to the model
and keeps the statically 'assumed' model in sync with its runtime
counterpart. Since defining each and every method manually is rather
tiresome, `transitions.experimental.utils.generate_base_model`
features a way to convert a machine configuration into a `BaseClass`
with all convenience functions and callbacks.
+ Add `transitions.experimental.utils.{add_transitions, event,
with_model_definitions, transition}` to define trigger methods in a
class model for more convenient type checking. `add_transitions`
can be used as a function decorator and is stackable. `event` returns
a placeholder object for attribute assigment. `add_transitions` and
`event` have the same signature and support transition definition like
machine constructors. The function `transition` can used for better
typing and returns a dictionary that can be passed to the utility
functions but also to a machine constructor. `add_transitions` and
`event` require a machine decorated with `with_model_definitions`.
Decorating a machine `with_model_definitions` implies `model_override=True`.
* Feature: Add `may_trigger` to models to check whether transitions can
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-transitions?expand=0&rev=24
* removed legacy implementation of `HierarchicalMachine` from
the package
* Bug #551: Fix active state styling in `GraphMachine` (thanks
@betaboon)
* Bug #554: Fix issues related to scopes and queueing in
`HierachicalMachine` (thanks @jankrejci)
* Bug #568: Reflexive transitions (dest: '=') had not been
resolved correctly when source was a wildcard (thanks @jnu)
* Bug #568: HSM did not detect reflexive transitions if src was
a parent state (thanks @lostcontrol)
* Bug #569: Fix implicit fallback to `graphviz` when
`pygraphviz` was not installed (thanks @FridjofAmundsen)
* Bug #580: Fix `on_timeout` callback resolution when timeout
had been initialized with `timeout=0` (thanks @Rysbai)
* Bug #582: Last label in `GraphSupport` was not correctly
aligned when `show_attributes=True` (thanks @spagh-eddie)
* Feature: Add pyi stub files for better type hinting. Since
many functions and constructors allow rather arbitrary
arguments time will tell whether typing should be strict (and
cause more mypy issues) or more relaxed (and thus less
precise).
* Feature: Reviewed and improved method documentation
* Feature #549: Add `may` transition check to transitions
(thanks @artofhuman)
* Feature #552: Refactored error handling to be able to handle
`MachineError` in `on_exception` callbacks (thanks @kpihus)
* Feature: Add `mypy` to test workflow
* PR #461: Add `Retry` state to supported state stereotypes
(thanks @rgov)

- Update to version 0.8.10
* Feature #545: The literal 'self' (default model parameter of
Machine) has been replaced by the class variable
Machine.self_literal = 'self'. Machine now performs an identity
check (instead of a value check) with mod is self.self_literal
to determine whether it should act as a model. While 'self'
should still work when passed to the model parameter, we
encourage using Machine.self_literal from now on. This was done
to enable easier override of Machine.__eq__ in subclasses
(thanks @VKSolovev).
* Bug #547: Introduce HierarchicalMachine.prefix_path to resolve
global state names since the HSM stack is not reliable when
queued=True (thanks @jankrejci).
* Bug #548: HSM source states were exited even though they are
parents of the destination state (thanks @wes-public-apps).
- Don't test optional extra graphviz on python36: pygraphviz
dropped Python 3.6 support

OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-transitions?expand=0&rev=18
- Update to version 0.8.9
Bugfix
* NestedEvent now wraps the machine's scope into partials passed
to HierarchicalMachine._process. This prevents queued
transitions from losing their scope.
Feature
* (A)Graph.draw function (object returned by
GraphMachine.get_graph()) can be passed a file/stream object
as first parameter or None. The later will result in draw
returning a binary string. (thanks @Blindfreddy).
* Use id(model) instead of model for machine-bound caches in
LockedMachine, AsyncMachine and GraphMachine. This might
influence pickling.

- Update to version 0.8.8
Bugfix
* AsyncMachine does not remove models when remove_models is
called.
Feature
* Introduce try/except for finalize callbacks in Machine and
HierachicalMachine. Thus, errors occurring in finalize
callbacks will be suppressed and only the original error will
be raised.
* Show references in graphs and markup. Introduce
MarkupMachine.format_references to tweak reference formatting.
* Introduce Machine.on_exception to handle raised exceptions in
callbacks.
* Machine.get_triggers now supports State and Enum as arguments.
* NestedState and HierachicalMachine.add_states now accept
(lists of) states and enums as initial parameter.
- Update to version 0.8.7
* State configuration dictionaries passed to HierarchicalMachine
can also use states as a keyword to define substates. If
children and states are present, only children will be
considered.
* HierarchicalMachine with custom separator now adds
is_state partials for nested states (e.g. is_C.s3.a()) to
models.
* Use model_attribute consistently in AsyncMachine.
* HierarchicalMachine now checks whether state_cls, event_cls
and transition_cls have been subclassed from nested base
classes (e.g. NestedState) to prevent hard to debug
inheritance errors
- Update to version 0.8.6
OBS-URL: https://build.opensuse.org/request/show/883668
OBS-URL: https://build.opensuse.org/package/show/devel:languages:python/python-transitions?expand=0&rev=15
- Update to version 0.8.2
* Improved testing without any optional graphviz package
* _check_event_result failed when model was in parallel state
* Only allow explicit dest=None in Machine.add_transition (not
just falsy) for internal transitions
* Fix state creation of nested enums
* HierarchicalGraphMachine did not find/apply styling for
parallel states
* Bugfix: Model.trigger now considers the machine's and current
state's ignore_invalid_triggers attribute and can be called
with non-existing events
* Child states may not have been exited when the executed
transition had been defined on a parent
* Introduced transitions.extensions.asyncio.AsyncTimeout as a
state decorator to avoid threads used
in transitions.extensions.state.Timeout
* Use sets instead of lists to cache already covered transitions
in nested state machines
* Improve handling of unresolved attributes for easier inheritance
* Refactored AsyncMachine to enable trio/anyio override
