Par2 sets, NZBs and SFVs were sniffed from their first segment and then
read whole, downloading that segment a second time.

SeedService looked up every file of a batch across all files partitions
after inserting it (15% of Postgres' active time); the merge job read
every release on each GC sweep.

Par2 naming needs the fingerprint inspection stores on a binary, and the
GC deleted seeded binaries (6 h unfingerprinted, 48 h stale) long before
the inspection queue reached them. binaries.awaiting_inspection protects
them for up to 7 days; the GC deletes use partial indexes so they don't
read past waiting rows. Seeding no longer creates binaries for files that
aren't inspected (~85% of a.b.ath), which only churned the table.

Half the live leases go to higher-priority ranges, the rest to the others,
so a slow recent gap runs beside older history. With no article
connections the article relay answers 503 instead of waiting forever.

Measured with 20 relay connections, plain and gzip both gave ~1.5 chunks/s
for 2026 a.b.ath articles; plain used many times the CPU and traffic.

For 2026 a.b.ath articles Eweka's gzip replies have a long tail (p90 12.4 s
per 20k vs 3.9 s plain; 6.1k vs 10.5k headers/s). SEED_NNTP_COMPRESS turns
compression back on; plain replies are deflated for nodes asynchronously.

Dense recent a.b.ath ranges produced batches over the 64 MB body limit
(413). The node now posts such a batch in halves; only the second moves
the range's resume point.

Copying all existing keys in the migration read the files rows from the
HDD for over half an hour and held up the deploy. gc:scheduler now copies
them in slices (FILE_KEYS_FILL_SECONDS per sweep) and FileStore checks
every partition until the fill is complete.

- seed:plan plans every part of a group's history no range covers (it
started below the lowest known range and left a.b.ath's 13 most recent
months out); seed_ranges.priority orders leases (seed:plan --priority).
- binaries.part_count, kept by the parts insert in the same statement:
claimCompleted compares it instead of counting parts every batch.
- file_keys: 64-bit hashes of all file keys; FileStore.insert asks it
before probing every files partition.
- worker:file stores 100 completed binaries per job with set-based queries.

matchPar2Releases checked every same-size release_files row's set and
date (18 s per batch of body-derived binaries); now an index on
release_files (release_id, size) drops the repeated sizes first: 0.16 s.
File inserts updated their release in four row triggers; one statement
trigger now updates each release once per INSERT. Completeness is noted
in release_dirty and recomputed by gc:scheduler every 30 minutes.

One process ran everything on one core. SEED_PROCESSES (default: the

release_complete() matched each par2-listed file through a correlated
subquery that scanned all binaries per listed file, run twice per
inserted release_files row: one insert of a few thousand rows ran for
20+ minutes. It now reads the release's files once by release id, and
release_files refreshes once per INSERT statement.
seed:node's SEED_CONNECTIONS/--connections is now SEED_RANGES/--ranges.

Inspection is split into prepare (database), probe (lib/content/probe:
downloads, decoding and parsing, no database) and apply (database).
worker:collection runs all three; seed:node with SEED_INSPECTORS leases
jobs from the same queues through the seed API (BullMQ manual leases),
fetches articles through the seed API and posts the probes back.
A node now needs only SEED_URL and SEED_TOKEN: the settings the app
requires but a node never uses get placeholders for seed:node.

One poster adds the same 22 GB hidden '.1917-….mkv' decoy to every 7z
upload; the largest-entry rule named 840 releases after it. Entries with
a hidden path part are skipped; release:rename --hidden renames the
existing ones from their stored listing.

85% of the 7z archives inspected have encrypted headers (-mhe). Their
encoded header lists the 7zAES coder, so the packed header stream is no

A batch of a dense range (over ~5,400 files) exceeded Postgres' 65,535

Inspection lists only the entries whose headers are in the first segment
of a first volume. A walk hops from header to header, fetching one segment
per entry and volume, in its own queue (one job per collection worker) on
NNTP connections inspection isn't waiting for. content:walk-archives queues
releases inspected earlier (CONCEPT D40).

The four ranges kept failing on fresh connections too: in gzip mode Eweka
stops some chunks partway (a.b.ath 49701720000: 19,672 of 20,000
overviews, the last line cut, then silence), while the same chunk without
compression comes in 0.3 s. A failed relay chunk is now retried once
without compression on a connection of its own (dead pooled connections are
covered by the same retry).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Five ranges "never answered" in 10 minutes, yet their chunk came back in
0.3 s on a fresh connection: the news server drops idle connections
without telling, and the pool's next request on one waited for the
10-minute inactivity timeout. Now: SEED_NNTP_TIMEOUT_MS 90 s (inactivity;
slow ranges keep streaming), one retry on a fresh connection, and pooled
connections idle over 60 s are replaced before use.

About 5% of seeded headers are fragments. They went through staging,
where they waited 30 minutes for parts that were never coming (the
neighbouring range is worked on by another node, often hours later) and
expired: the staging table grew to 22 GB and the NVMe part of the database
reached its 60 GB limit, which stopped leasing and the backfill. Files cut
by a range edge can still be completed by the neighbouring range, so
fragments within 50k articles of an edge go straight into binaries and
parts; the rest, files with articles missing for good, are dropped.

- A range reported to its end but not finished (its node went away at
the very end) was leased again with start past end; nodes asked for
"from 49208000000 to 49207999999", got 400, and the range failed after
five leases. The orchestrator now marks such ranges done before
leasing, and runRange reports them done without fetching.
- Some old ranges come so slowly that one XOVER of 20k headers takes over
two minutes: five ranges failed on "NNTP reply timed out". The relay
pool's timeout is SEED_NNTP_TIMEOUT_MS (default 10 minutes, the node's
HTTP timeout).

A failure after the old parent is dropped would leave files half-converted;

Seeding adds ~14M files a day; 32-bit ids run out at 2.1 billion in about
five months. Postgres can't change a partition key's type, so the
migration detaches the partitions, rewrites each as a plain table (a CHECK
added first spares the attach scan), and attaches them to a new 64-bit
parent with the same indexes, foreign keys and triggers. binaries.file_id
and the id sequence become 64-bit too. Meant to run with the writers
stopped and Postgres on wal_level=minimal (compose: PG_WAL_LEVEL,
PG_MAX_WAL_SENDERS).

New rows went into free space scattered through the 9.6 GB heap on the HDD
(left behind by inspection's updates): one random HDD read per insert, and
seed batches took a median 13 s to store. The existing table becomes the
first partition as it is (a CHECK scan, no rewrite; indexes, its foreign
key and the triggers are taken over by the partitioned parent); new
partitions of 4M ids go in the same tablespace and stay in memory while
they fill.
- Every partition has a unique file_key index; FileStore.insert looks keys
up in all partitions first (a key can't be unique across partitions).
- FilePartitions.ensure() (gc:scheduler) keeps two partitions ahead.
- Stats count files from the partitions; seed:node waits ~20 minutes for
the API before giving a range up.

The seed API keeps a pool of NNTP connections (SEED_NNTP_CONNECTIONS) and
serves GET /api/v1/seed/ranges/:id/chunk?from=&to= for leased ranges:
the gzip stream the news server sent, passed on unopened. seed:node fetches
that way by default (SEED_FETCH=relay), so a node needs only a token and
SEED_CONNECTIONS; SEED_FETCH=direct keeps its own NNTP connections. All
fetching then comes from the indexer's IP (the account allows two).

A failed NNTP login gives the range back uncounted (no attempt used), and a
node with nothing to lease holds no connection. Replaces log-in-before-lease,
which kept idle connections and logged in again every minute while idle.

- seed:node logs in to NNTP before taking a range and keeps the connection
across ranges (replaced after 2 minutes idle or a failed range). A node
that can't reach its news server takes no range: two ranges were set
aside as failed while an office node's tunnel was being set up
(ECONNREFUSED 127.0.0.1:1563, five leases each). After an IP-address
limit refusal it waits 5 minutes.
- NNTP_TLS_SERVERNAME: the hostname the TLS certificate is checked
against when NNTP_HOST is a tunnel ("Hostname/IP does not match
certificate's altnames: Host: localhost").
- seed-node/README: the IP-address limit and tunnelling.

A seeding node that waited over two minutes for the seed API (restarting)
had its idle NNTP connection closed by its own timeout, and gave its range

No new range while the database's NVMe part or the hdd tablespace is over
BACKFILL_MAX_NVME_GB / BACKFILL_MAX_HDD_GB; nodes ask again a minute later.

with a plan for all of a.b.ath queued.

At most two posts waiting; a failed post stops the chain, so nothing is

- seed_nodes (hashed bearer tokens) and seed_ranges (planned ranges with
lease, resume point and counts); migration …140.
- SeedOrchestrator: lease (oldest plan first, FOR UPDATE SKIP LOCKED; a
lease without a batch for 15 min passes to the next node and resumes at
next_id), batch (stores files and fragments, moves next_id), finish,
release, plan (from below live indexing / the backfill / earlier plans
down to N days back; takes over the group's backfill), status.
- Seed API under /api/v1/seed (lease, ranges/:id/batches|done|release,
status) behind a node-token middleware; JSON bodies up to 64 MB after
gzip.
- seed:node runs a node: no database or Redis, outgoing HTTPS only, N
connections, gzip batches, retries for network errors and 5xx, drops a
range on 409, gives its ranges back on SIGTERM. seed-node/ has a compose
file that builds the image from this repository.
- seed:token, seed:plan, seed:status for the operator. Header parsing moved
to lib/ingest and the range loop to lib/seed/runner, shared by seed:range
and seed:node.

- lib/nntp/xover_client: a minimal one-connection client for seed:range
with XFEATURE COMPRESS GZIP (a zlib stream after "224 … [COMPRESS=GZIP]",
then a "." line; 420 for an empty range). About 6x less header traffic.
Overviews come out with the field names nntp-js uses.
- SfvService.claimAll: one sfv_entries lookup per stored batch.
- Fragments go through the regular ingest path beside fetching (at most
two batches in flight); a failure fails the run at the end.

A seeding node fetches a range over one NNTP connection, parses headers
with the live rules, groups them into files in memory (lib/aggregate) and
stores per complete file its release, the file and a completed binary
(SeedService), instead of one parts row per article. What doesn't complete
within the window goes through the regular ingest path as fragments.
`--dry-run` only fetches and aggregates, to measure a node.

The first version matched extensions in search_text, which was wrong and
slow: file names enter search_text as stems without extension (so plainly
posted .mkv files were missed), and matching the TOASTed text took 3-4 s
for common types.
- Migration …130: releases.extensions text[] (two to four characters with
a letter; .7z.001 and .r00 count as 7z and rar), kept current by triggers
on files (name, release) and on releases (archive listing), filled with
one sequential pass over files, with a GIN index.
- Search: ext matches with `extensions && ?`.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- API: min_size and max_size in MB, ext as a comma-separated list. An
extension matches as a whole word in search_text (file and entry names,
dots as spaces), so "iso" finds .iso files but not "ISOLATION", which a
plain search word matched as a substring. The trigram index serves it.
- Web UI: a size range and an extension field in the filter row, kept in
the URL like the other filters.

Of 5,000 waiting inspection jobs, 3,212 were queued only because their
stem looked random, and 2,044 of those were later RAR volumes
(xyz.part47.rar, .r00) or par2 recovery volumes (.vol03+04.par2). Their
first segment adds nothing: the set is listed from its first volume and
named from its index .par2, as for readable names already. Each one cost a
~700 KB download; inspection pulled ~85 MB/s and fell behind the backfill.
- isCandidate() rejects later volumes (isLaterVolume) before the random-
name rule.
- worker:file only queues files that are candidates, so the ~30% that
inspection skips anyway no longer take queue slots.

Crossposts, reposts and backfill ranges keep bringing articles of files
that worker:file already created. Ingest inserted their header parts again,
and GC's copied-parts pass (which searched all binaries for parts on every
batch) removed only 150k-450k per sweep: parts grew to 68M rows, 56M of
them belonging to finished files, and the 23 GB table paused the backfill.
- Ingest skips header parts (no per-part CRC) for binaries with a file_id.
- GC drops copied parts with a cursor over binaries, 2000 per statement.

Spotnet (CONCEPT D29):
- Index free.pt fully and import spots with their descriptions, categories
and NZBs; a spot renames its release, since Spotnet names are more
trustworthy than names derived from subjects.
- Find passwords in spot descriptions too, and tell "needs a password we
have" from "needs a password we don't have".
Content inspection:
- List the contents of 7z (.7z.001) archives, SFV sets, nicovideo uploads
and other archive-like files; mark yEncBin .bin containers as encrypted.
- Take real names from yEnc headers for randomly named files, and merge
uploads that were split across posts.
Storage (D31, D32):
- Store segment lists zstd-compressed behind the FileStore accessor.
- group:backfill indexes older headers at low priority and pauses when
the NVMe or HDD part of the database gets too large.
Grouping (D35, D36):
- Lone header segments wait in staged_segments until a second segment of
their file arrives, which drops the per-article junk binaries.
- Counter grouping joins random-subject uploads by poster, [i/M] counter,
part count and day.
Search and maintenance (D33, D34):
- A trigram-indexed search_text column, smaller indexes, estimated stats.
- Passes that clean up nonsense names; weekly index maintenance; GC budgets
per kind.
- Web UI: grey out stale results while a search runs and cancel superseded
requests. Count only up to 1,000 matches for the page, which made filter
clicks take seconds (Newznab keeps the 10,000 cap).
