Since key refresh is prone to failure, retry using exponential |
| 2 |
backoff with random jitter. This adds the following sync-openpgp-* |
| 3 |
configuration settings: |
| 4 |
|
| 5 |
sync-openpgp-key-refresh-retry-count = 40 |
| 6 |
|
| 7 |
Maximum number of times to retry key refresh if it fails. Between |
| 8 |
each key refresh attempt, there is an exponential delay with a |
| 9 |
constant multiplier and a uniform random multiplier between 0 and 1. |
| 10 |
|
| 11 |
sync-openpgp-key-refresh-retry-delay-exp-base = 2 |
| 12 |
|
| 13 |
The base of the exponential expression. The exponent is the number |
| 14 |
of previous refresh attempts. |
| 15 |
|
| 16 |
sync-openpgp-key-refresh-retry-delay-max = 60 |
| 17 |
|
| 18 |
Maximum delay between each retry attempt, in units of seconds. This |
| 19 |
places a limit on the length of the exponential delay. |
| 20 |
|
| 21 |
sync-openpgp-key-refresh-retry-delay-mult = 4 |
| 22 |
|
| 23 |
Multiplier for the exponential delay. |
| 24 |
|
| 25 |
sync-openpgp-key-refresh-retry-overall-timeout = 1200 |
| 26 |
|
| 27 |
Combined time limit for all refresh attempts, in units of seconds. |
