clawbot	281d162e27	Show figures of the routing table on the home page (closes #154) ... The home page gets cards for the newest and oldest kept route, the newest and oldest updated AS, the AS with the most prefixes, the ASes with a single prefix and fifteen well-known networks. Two more cards count the bogon announcements and the prefixes with several origin ASes. They link to the new pages /bogons and /multiple-origins, which list up to 1,000 entries each. The new package internal/bogon tells reserved prefixes and AS numbers, from the IANA special-purpose and address space registries. Table.Overview walks the table and lets the read lock go every 10,000 prefixes. The server works the cards out once a minute and serves that copy. A new index on asns(last_seen) finds the newest and oldest updated AS. Model: opus-5-5	2026-10-27 18:27:01 +01:00
clawbot	bac531c76d	Write the routing table every second and read it at startup (part of #122) ... The prefix handler applies each update to the routing table in memory as it handles it, sorted into announcements and withdrawals as for the live route tables. Each flush first writes at most 20,000 of the table's changed pairs, with every new peer; the rest follow in the next flushes. A failed write puts its changes and new peers back in the table. Stop makes one last flush, and logs the changed pairs left. Startup reads the table before the streamer connects, and logs its pairs, peers and time. The per-peer counts are a slice, so the read takes about a third less time. The health check's start period is 60 seconds, so a full table's read fits before upaas looks.

clawbot	eda37da369	Store the routing table in the database (part of #122) ... A new routes table holds one row per prefix and origin AS: the peer set as the bitset's bytes, and the two kept routes, each with its peer's number, AS path and time in seconds. A new route_peers table holds each peer's number and address. WriteRouteChanges writes one TakeChanges result in a transaction. ReadRouteTable reads both tables into a new routing table, through the new Table.Load, which records no change. It fails on a row that names a peer number missing from route_peers. Nothing uses them yet. Model: opus-5-5	2026-10-27 08:54:57 +01:00
clawbot	7a34a46c4d	Add internal/routetable, the routing table in memory (part of #122) ... A new package holds every prefix some peer carries. For each prefix and origin AS it keeps the set of peers that carry it, one bit per peer, and the two newest of their routes in full. It applies announcements, withdrawals and peers' sessions going down by the rule confirmed on the issue, and records which pairs changed for the database writes to come. It answers the IP lookup, an AS's prefixes, a prefix's origins, a sample of one mask length, and the counts the stats show. Nothing uses it yet. The peer sets use github.com/bits-and-blooms/bitset. The kept routes' times are held in order in github.com/google/btree, so the oldest and newest need no scan. Model: opus-5-5	2026-10-27 07:51:55 +01:00
