Snapshots are not contiguous

[centromere]

Hello. I am trying to bootstrap a leap 5.0.0 node completely from the snapshots provided here. I want my blocks.log file to begin from genesis. Unfortunately, there does not seem to be a way to achieve this. I tried restoring from snapshot-2024-01-30-22-eos-v6-0354914962.bin, and while that worked successfully, it doesn't give me all the blocks prior to 354914963. When I tried to add the next snapshot in the list, I received this error:

error 2024-01-31T03:11:53.793 nodeos    main.cpp:209                  main                 ] 3190000 block_log_exception: Block log exception
Block log is provided with snapshot but does not contain the head block from the snapshot nor a block right after it
    {"snapshot_head_block":354893362,"block_log_first_num":354914963,"block_log_last_num":354937726}
    nodeos  controller.cpp:928 read_from_snapshot

    {}
    nodeos  chain_plugin.cpp:1158 plugin_startup

I am invoking leap as follows:

nodeos --data-dir=/var/db/leap --config-dir=/etc/leap/config --plugin=eosio::chain_plugin --plugin=eosio::chain_api_plugin --protocol-features-dir=/etc/leap/protocol_features --wasm-runtime=eos-vm-jit --abi-serializer-max-time-ms=10000 --chain-state-db-size-mb=8388608 --chain-threads=16 --eos-vm-oc-compile-threads=4 --disable-replay-opts --plugin=eosio::http_plugin --http-server-address=[::]:8888 --http-max-response-time-ms=1000 --verbose-http-errors --http-validate-host=false --http-threads=16 --plugin=eosio::net_plugin --plugin=eosio::net_api_plugin --p2p-listen-endpoint=:9876 --p2p-server-address=:9876 --p2p-peer-address=eos.seed.eosnation.io:9876 --p2p-peer-address=peer1.eosphere.io:9876 --p2p-peer-address=p2p.genereos.io:9876 --net-threads=8 --sync-fetch-span=5000 --plugin=eosio::producer_plugin --plugin=eosio::producer_api_plugin --snapshots-dir=/var/db/leap/snapshots --plugin=eosio::state_history_plugin --state-history-dir=/var/db/leap/block/state-history --trace-history --chain-state-history --state-history-endpoint=[::]:8080 --trace-history-debug-mode --logconf=/etc/leap/config/logging.json --snapshot=snapshots/snapshot-2024-01-30-19-eos-v6-0354893362.bin

Is this user error? Are the official snapshots intended to be non-contiguous? I do not want to wait months for the node to sync.

If you want the blocks to start from genesis, either you need to sync from genesis or download a blocks.log from someone. Snapshots only contain the state at exactly the time (block height) of the snapshot. No history.

@matthewdarwin how big is a full block log now for EOS?
