luxos.asyncops.RETRIES = 0#

default number (>1) of retries on a failed operation

luxos.asyncops.RETRIES_DELAY = 1.0#

delay (s) between retries

luxos.asyncops.TIMEOUT = 3.0#

default timeout (s) for operations

async luxos.asyncops.rexec(host: str, port: int, cmd: str, parameters: str | int | float | bool | list[Any] | dict[str, Any] | None = None, timeout: float | None = None, retry: int | None = None, retry_delay: float | None = None) → dict[str, Any] | None#

Send a command to a host.

Parameters:

  • host – A string representing the host IP or a name.

  • port – An integer representing the port number to connect to.

  • cmd – A string representing the command to execute.

  • parameters – Any additional parameters for the command.

  • timeout – A float representing the maximum time in seconds to wait for a response before timing out.

  • retry – Optional. An integer representing the number of times to retry the command execution in case of failure.

  • retry_delay – Optional. A float representing the delay in seconds between each retry attempt.

Returns:

A dictionary containing the response from the execution of the command.

Raises:

Any exception that occurs during the execution of the command. –

Notes

If timeout/retry/retry_delay aren’t provided (or None), they will default to the module level values (TIMEOUT, RETRIES, and RETRIES_DELAY).

This function will handle logon/logoff automatically.

luxos.asyncops.validate(res: dict[str, Any], extrakey: str | None = None, minfields: None | int = None, maxfields: None | int = None) → Any#

Validate a message returned from a miner.

Parameters:

  • res – The dictionary returned from a miner.

  • extrakey – if present it will try to extract it from res.

  • cmd – A string representing the command to execute.

  • minfields – The min length of the field extrakey.

  • maxfields – The max length of the field extrakey.

Returns:

A dictionary containing the response from the execution of the command if extrakey is None, else a dict or a list of items.

Raises:
