retryp
From the Jargon File:
The -P Convention Turning a word into a question by appending the syllable ‘P’; from the LISP convention of appending the letter ‘P’ to denote a predicate (a boolean-valued function). The question should expect a yes/no answer, though it needn't. (See T and NIL.)
retryp is yet another retry decorator, with nothing particularly special about it other than it being both well-featured and not rewriting or hiding the calling signature of the wrapped method (allows for accurate code introspection – a Big Deal for me).
Thanks go to Graham Dumpleton and his wrapt package for that latter.
Arguments
- count
Default: 10
Number of times to retry the wapped item. If set to “0”, will retry 1073741823 times because a) that’s a lot, b) give up already, and c) nothing lasts forever.
- delay
Default: 10 (seconds)
The base delay between retry attempts.
- backoff
Default: 10
A multiplicative factor applied to the delay, used to provide increasing backoff as subsequent attempts continue to fail.
- jitter
Default 0
Extra random seconds will be added to each retry delay, ranging from 0 to the value of jitter.
- refuse_rc_fn
Default: None
If provided, the return of the wrapped item will be passed as the only argument to this function. If refuse_rc_fn (rc) evaluates to True, then no further retries will be made.
- refuse_exc_fn
Default: None
If provided, any exception raised by the wrapped item will be passed as the only argument to this function. If refuse_exc_fn (e) evaluates to True, then the exception will be raised again and retry attempts will cease.
- expose_last_exc
Default: False
By default retryp will raise retryp.FailedTooOften if the wrapped item continues to fail after the requested number of attempts. If expose_last_exc is set, then the exception raised by the wrapped item will be raised if the last attempt results in an exception.
- log_faults
Default: False
Log every exception raised by the wrapped item using logtool.log_fault.
- log_faults_level
Default: logging.DEBUG
Logging level at which exceptions will be logged by logtool.log_fault() when log_faults is set.
