In v3.3.77 the byse uploads started failing with "getaddrinfo ENOTFOUND
s1065.filemoon" / "s1070.filemoon" / "s1075.filemoon". The hostname has no TLD,
so DNS cannot resolve it. Root cause: byse's GET /upload/server is INTERMITTENTLY
handing back a truncated upload-server host — "sNNNN.filemoon" with the TLD dropped
(consistent with byse's ongoing filemoon migration; their own docs already expose an
old_domain/new_domain embed switch). Some uploads still work because byse returns the
complete host on those; the failing ones got truncated. byse did not change the API
contract — this is malformed data from their server pool.
The correct upload domain is NOT externally verifiable: every TLD that resolves for
these server IDs is a parked/squatter domain (filemoon.art -> ParkLogic "lander" PTR;
filemoon.nl -> a shared catch-all cert for kaobei.cc/babesex.xyz/...). Appending a TLD
would point uploads at a parking page (or a third party) — so we do NOT guess one.
Instead, treat an obviously-truncated host as "no valid server": normalizeAbsoluteUrl
now returns null for any host ending in the bare ".filemoon" label (never a real TLD).
extractUploadServerUrl then yields nothing for that response, so getUploadServer falls
through to its existing machinery — it retries the lookup (SERVER_RETRY_ATTEMPTS) to get
a different server and, crucially, returns the last-known-good server from
LAST_UPLOAD_SERVERS once one has been cached. So after any single complete response, the
truncated ones transparently reuse the good server instead of uploading into a DNS void.
If byse's whole pool is truncating (cold cache), the lookup fails CLEAN as hosterTransient
(no cascade, no blacklist — the v3.3.77 behavior), and the next batch tries again.
This composes with v3.3.77: ENOTFOUND was already transient (retry same account, no
failover); this stops the unresolvable host from ever reaching the POST in the first place
when a working server is available.
Tests: extractUploadServerUrl rejects https://sNNNN.filemoon / bare sNNNN.filemoon /
https://filemoon and keeps a complete host (https://s1065.filemoon.sx/...) untouched.
