prhandle to the original pending request
reply_anonymity_levelanonymity level for the reply, UINT32_MAX for "unknown"
expirationwhen does data expire?
last_transmissionwhen was the last time we've tried to download this block? (FOREVER if unknown)

◆ GSF_current_priorities

double GSF_current_priorities

Typical priorities we're seeing from other peers right now.

Since most priorities will be zero, this value is the weighted average of non-zero priorities seen "recently". In order to ensure that new values do not dramatically change the ratio, values are first "capped" to a reasonable range (+N of the current value) and then averaged into the existing value by a ratio of 1:N. Hence receiving the largest possible priority can still only raise our "current_priorities" by at most 1.
