Alex Sharov	d41d523050	Downloader: add ProhibitNewDownloads() (#8939) ... "whitelisting" mechanism (list of files - stored in DB) - which protecting us from downloading new files after upgrade/downgrade was broken. And seems it became over-complicated with time. I replacing it by 1 persistent flag inside downloader: "prohibit_new_downloads.lock" Erigon will turn downloader into this mode after downloading/verification of first snapshots. ``` //Corner cases: // - Erigon generated file X with hash H1. User upgraded Erigon. New version has preverified file X with hash H2. Must ignore H2 (don't send to Downloader) // - Erigon "download once": means restart/upgrade/downgrade must not download files (and will be fast) // - After "download once" - Erigon will produce and seed new files ``` ------ `downloader --seedbox` is never "prohibit new downloads"	2023-12-12 16:05:56 +07:00
