Tmtccmd

Changed

- Renamed `FsfwTmTcPrinter.get_validity_buffer` to `FsfwTmTcPrinter.get_validity_buffer_str`
- Renamed `ObjectId<$TY>.from_bytes` to `ObjectId<$TY>.from_bytes_typed` to avoid invalid override.

Added

- Added `fsfw.tmtc_printer.get_validity_buffer_str` function.

Removed

- Broken FSFW PUS 3, PUS 20, PUS 8 TM unpackers.

- Bumped `spacepackets` to release range >=0.24, <0.25.
- Bumped `cfdp-py` to v0.1.1.

Changed

- Renamed `DefaultProcedureParams` to `TreeCommandingParams`.
- Renamed `TcParams` to `CommandingParams`.
- Renamed `DefaultProcedureInfo` to `TreeCommandingProcedure`.
- Renamed `add_default_procedure_arguments` to `add_tree_commanding_arguments`.
- Renamed `TcProcedureType.DEFAULT` to `TcProcedureType.TREE_COMMANDING`.
- Replaced `TelemetryListT` by `List[bytes]`.
- Renamed `TcpSpacePacketsComIF` to `TcpSpacepacketsClient`.
- Renamed `UdpComIF` to `UdpClient`.

Removed

- `CoreServiceList` enumeration.
- `DEFAULT_APID` and `DEBUG_MODE` globals.

Fixed

- TCP client implementation re-worked to be thread-safe. Also added more graceful shut-down
handling. Consequently, the thread spawned by the TCP client is not daemonic anymore.

Fixed

- Fixed bug for acknowledged file transfer cancellation in the destination handler.

Removed

- The `tmtccmd.util.countdown` and `tmtccmd.util.seqcnt` module were moved to the `spacepackets`
library.
- Most of the `tmtccmd.cfdp` module was moved to the
[`cfdp-py` library](https://github.com/us-irs/cfdp-py).

Added

- Added new command tree mechanism which allows to specify the telecommand structure in a more
flexible way. This mechanism deprecated the old service/op code combination. The user can now
specify the whole command structure as a tree, and specify commands as a slash separated path
through that tree.

Removed

- Removed high level CFDP handler and CFDP in CCSDS handler which are not generic enough
and do not work in their current form. These handlers might be re-added with a proper
implementation which also allow building a CFDP daemon / full CFDP entity more easily.

Changed

- Move `tmtccmd.tmtc.base` to `tmtccmd.tmtc.tm_base` and deprecate it.

Added

- The CFDP source and destination handler can now also handle cancel requests.
- The CFDP source handler can handle acknowleded mode transfers now.
- New `from_seconds` classmethod for `Countdown` class.

Changed

- All CFDP exceptions are now exposed via the `tmtccmd.cfdp.exceptions` module.
- Both CFDP source destination handler now expect a `RemoteEntityCfgTable` for remote configuration
setup.
- CFDP source and dest handler now both have the `entity_id` property to retrieve the local ID.
- CFDP handler transmission mode and CFDP state are separate from each other now. The
transmission mode can be retrieved using a new `transmission_mode` property for both handlers,
and the `CfdpState` `BUSY_CLASS_2_ACKED` and `BUSY_CLASS_1_NACKED` variants were merged into a
`BUSY` variant.
- Setting a sequnce of space packet IDs for TCP space packet parsing is now mandatory
for the TCP communication interface. This avoids confusing errors during run-time.
- Removed some global usage for the TCP communication interface
- The CFDP source and destination handlers can now only handle one packet at a time. This makes
reasoning about the logic of those handlers, and subsequently extending and adapting them
a lot easier. Multiple packets can still be inserted by calling the `insert_packet` and
`state_machine` function consecutively.
- Moved all `pus_*` modules located inside the `tm` and `tc` module to the new`pus/tm` `pus/tc`
submodule.
- Renamed all `pus_*` modules to `s_*` modules (service)
- Renamed `funccmd` PUS modules to `action`.
- Unified `tc` and `tm` module into `tmtc` module. All `tmtccmd.tm` and `tmtccmd.tc` imports
needs to be replaced with `tmtccmd.tmtc`.
- The `CheckLimitProvider` abstraction must now be explicitely passed to the CFDP entity instead
of being passed via the remote configuration.
- `Countdown` class `timeout` property now returns a `timedelta` object to avoid inconsistency
of getter and setter property. There is a new `timeout_ms` property to returns the timeout
as milliseconds.

Removed

- Removed `serial_fixed_frame` module and `SerialFixedFrameComIF` class which has been
deprecated since v4.0.0a0.
- `SerialCommunicationType`: Removed `FIXED_FRAME_BASED` variant.
- Hardcoded AT91 paths in `QEMUComIF`.
- Removed deprecated TM modules.

Fixed

- Various fixes for the `QEMUComIF`.
- Fixed the check timer and check limit mechanism for CFDP. The `RemoteEntityCfg` not only
expects a `check_limit` integer field which defaults to 2.

- Changed package license from Apache-2.0 to dual Apache-2.0 or MIT.
- spacepackets version v18.0.0

Fixed

- Bugfix for destination handler: Clear out file data queue when handling it.

Changed

- TCP communication interface:
- Frame limit is optional now.
- Small change to allow handling more than 4096 bytes in one polling cycle.
- Renamed `args_to_params_tmtc` to `args_to_all_params_tmtc` and `args_to_params_cfdp` to
`args_to_all_params_cfdp`
- `PutRequest` model now stores both destination and source file path as a Python `Path`.

Added

- Added new `cfdp_args_to_cfdp_params` function which only performs the conversion of CFDP
argparse arguments to the internalized `CfdpParams` type.
- Explicit functions to convert internalized CFDP parameters to a put request:
1. `cfdp_req_to_put_req_get_req`
2. `cfdp_req_to_put_req_proxy_put_req`
3. `cfdp_req_to_put_req_regular`
- Generic `generic_cfdp_params_to_put_request` conversion function which converts the
internalized CFDP parameters to a put request based on heuristics.
