When we process pending channel updates, it can cause the node_announcement to be moved. Then, we process a new node_announcement and go to delete the old one, but it's already moved! Do the obvious thing, and refresh gossmap if necessary each time around the loop. ``` 2024-05-17T02:56:12.701Z **BROKEN** gossipd: gossip_store: get delete entry offset 554921761/585584347 (version v24.02.1-151-g6e2ab02-modded) 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: common/daemon.c:38 (send_backtrace) 0x55b4c962518b 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: common/status.c:221 (status_failed) 0x55b4c962e83e 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: gossipd/gossip_store.c:466 (gossip_store_get_with_hdr) 0x55b4c961b6e3 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: gossipd/gossip_store.c:491 (check_msg_type) 0x55b4c961b75d 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: gossipd/gossip_store.c:509 (gossip_store_set_flag) 0x55b4c961b8e0 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: gossipd/gossip_store.c:561 (gossip_store_del) 0x55b4c961bb26 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: gossipd/gossmap_manage.c:913 (process_node_announcement) 0x55b4c961c472 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: gossipd/gossmap_manage.c:1111 (reprocess_queued_msgs) 0x55b4c961d6a6 2024-05-17T02:56:12.701Z **BROKEN** gossipd: backtrace: gossipd/gossmap_manage.c:670 (gossmap_manage_handle_get_txout_reply) 0x55b4c961d840 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: gossipd/gossipd.c:585 (recv_req) 0x55b4c9619e6a 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: common/daemon_conn.c:35 (handle_read) 0x55b4c9625436 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: ccan/ccan/io/io.c:59 (next_plan) 0x55b4c96b8506 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: ccan/ccan/io/io.c:407 (do_plan) 0x55b4c96b898d 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: ccan/ccan/io/io.c:417 (io_ready) 0x55b4c96b8a26 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: ccan/ccan/io/poll.c:453 (io_loop) 0x55b4c96ba315 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: gossipd/gossipd.c:683 (main) 0x55b4c961a84c 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: ../csu/libc-start.c:308 (__libc_start_main) 0x7f3931a3dd09 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: (null):0 ((null)) 0x55b4c9616d39 2024-05-17T02:56:12.702Z **BROKEN** gossipd: backtrace: (null):0 ((null)) 0xffffffffffffffff 2024-05-17T02:56:12.702Z **BROKEN** gossipd: STATUS_FAIL_INTERNAL_ERROR: gossip_store: get delete entry offset 554921761/585584347 ``` Reported-by: Vincenzo Palazzo Fixes: ElementsProject#7320 Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
