internal/eusupply replaces the old Node scraper (eu-supply.js) for
uk.eu-supply.com. The site has no API, so it posts the public search
form, which now needs the form's current defaults and reads the HTML
with golang.org/x/net/html. Each tender not stored yet has its own
page read too, for its description, contract type, CPV codes and
buyer address. Tenders are stored with the source "EU Supply - UK"
as eusupply-uk-<tender id>, with one release holding the tender as
read.
The site publishes no rate limit, so the client sets its own: one
request at a time, with a random wait between
sources.eu_supply.request_min_gap and request_max_gap (2s to 10s).
The source has the same 7-day backfill as Find a Tender's.
Most of its tenders are also on Find a Tender, so a new one is stored
Hidden and Skipped when another source's opportunity released within
30 days has a title at least 90% alike, and its buyer or description
matches too (80% of the shorter one's significant words).
which runs a plain TCP server for receiving websocket hub clients, with
server config, CSRF and rate limit middleware.
- internal/websocket: Hub pushing messages to WebSocket clients (ServeHTTP,
example.com/ws upgrade with optional CSRF check) and plain TCP clients (ServeTCP,
newline-delimited JSON envelopes); ping/pong keepalive, per-client message
rate limit, slow consumer handling, graceful Shutdown, debug logging of
messages sent and received
- internal/websocket/tcpserver: standalone TCP server for a hub, with accept
back-off, a per-IP connection limit (server.websocket.connection_limit) and
graceful shutdown
- internal/cli/wsserve: `wsserve` command running the TCP server, with
--listen/--host/--port overrides
- internal/middleware: keyed token bucket rate limiter, real client IP from
trusted proxies
- internal/httpx: RFC 9457 problem responses, request IDs in context
- internal/config: server section (host, port, shutdown timeout, rate limiter
idle TTL, websocket); util.ByteSize settings (e.g. "32KiB"); lists of
sections as single keys; empty lists stored as nil; isExplicitlySet for
printLoadedConfig; JobSearchConfigSource renamed to JSCSourcesSource;
TestSections checks every section's methods
- internal/util: ByteSize, parsed and formatted with go-humanize
