description	Manual end-to-end verification of started -> completed peer lifecycle using the HTTP tracker announce/scrape endpoints with curl (or browser for stats).

Manual HTTP Download-Completion E2E

Purpose

This skill verifies manually that an HTTP peer transition from started to completed updates tracker state correctly:

• announce response changes from leecher view to seeder view
• scrape stats change (incomplete -> complete, downloaded increments)
• global tracker stats change (seeders and completed increment)

This is a fast diagnostic workflow. It complements automated E2E (for example, src/bin/qbittorrent_e2e_runner.rs).

This same started-to-completed scenario can also be exercised with the HTTP tracker client, similar to the UDP workflow in .github/skills/dev/testing/manual-udp-download-completion-e2e/SKILL.md. This skill intentionally documents a generic HTTP client approach (curl/browser), so contributors can reproduce the flow without relying on a specific tracker client binary.

Prerequisites

Run all commands from repository root.

• HTTP tracker: http://127.0.0.1:7070
• Stats API: http://127.0.0.1:1212/api/v1/stats?token=MyAccessToken

Optional clean baseline:

rm -f ./storage/tracker/lib/database/sqlite3.db

1. Start tracker

In terminal A:

cargo run

Expected startup excerpt:

Loading extra configuration from default configuration file: `./share/default/config/tracker.development.sqlite3.toml` ...
... HTTP TRACKER: Started on: http://0.0.0.0:7070
... API: Started on: http://0.0.0.0:1212

2. Define test values

In terminal B:

INFO_HASH='TTTTTTTTTTTTTTTTTTTT'
PEER_ID='HTTPCLIENTPEERID0000'
BASE='http://127.0.0.1:7070'
STATS='http://127.0.0.1:1212/api/v1/stats?token=MyAccessToken'

Notes:

• INFO_HASH must be exactly 20 bytes in this curl workflow.
• PEER_ID must be exactly 20 bytes.

3. Baseline checks

3.1 Global stats

  "leechers": 0,
  "tcp4_connections_handled": 0,
  "tcp4_announces_handled": 0,
  "tcp4_scrapes_handled": 0,

  "udp_requests_banned": 0,
  "udp_banned_ips_total": 0,
  "udp_avg_connect_processing_time_ns": 0,
  "udp_avg_announce_processing_time_ns" 
   
   
   
   
   
   
   
   
   
   
   
   
   

3.2 Torrent scrape

Command:

curl -sG "$BASE/scrape" --data-urlencode "info_hash=$INFO_HASH"

Output captured during validation:

d5:filesd20:TTTTTTTTTTTTTTTTTTTTd8:completei0e10:downloadedi0e10:incompletei0eeee

4. Announce started

Command:

curl -sG "$BASE/announce" \
  --data-urlencode "info_hash=$INFO_HASH" \
  --data-urlencode "peer_id=$PEER_ID" \
  --data-urlencode "port=6881" \
  --data-urlencode "uploaded=0" \
  --data-urlencode "downloaded=0" \
  --data-urlencode "left=1000" \
  --data-urlencode "event=started" \
  --data-urlencode "compact=1" \
  --data-urlencode "numwant=0"

Output captured during validation:

d8:completei0e10:incompletei1e8:intervali120e12:min intervali120e5:peers0:6:peers60:e

Then verify scrape and global stats:

curl -sG "$BASE/scrape" --data-urlencode "info_hash=$INFO_HASH"
curl -s "$STATS"

Outputs captured during validation:

d5:filesd20:TTTTTTTTTTTTTTTTTTTTd8:completei0e10:downloadedi0e10:incompletei1eeee

{
  "torrents": 1,
  "seeders": 0,
  "completed": 0,
  "leechers": 1,
  "tcp4_connections_handled": 3,
  "tcp4_announces_handled": 1,
  "tcp4_scrapes_handled": 2,
  "tcp6_connections_handled": 0,
  "tcp6_announces_handled": 0,
  "tcp6_scrapes_handled": 0,
  "udp_requests_aborted": 0,
  "udp_requests_banned": 0,
  "udp_banned_ips_total": 0,
  "udp_avg_connect_processing_time_ns": 0,
  "udp_avg_announce_processing_time_ns" 
   
   
   
   
   
   
   
   
   
   
   
   
   

Expected meaning:

• incomplete became 1
• global leechers became 1
• global completed still 0

5. Announce completed

Command:

curl -sG "$BASE/announce" \
  --data-urlencode "info_hash=$INFO_HASH" \
  --data-urlencode "peer_id=$PEER_ID" \
  --data-urlencode "port=6881" \
  --data-urlencode "uploaded=0" \
  --data-urlencode "downloaded=1000" \
  --data-urlencode "left=0" \
  --data-urlencode "event=completed" \
  --data-urlencode "compact=1" \
  --data-urlencode "numwant=0"

Output captured during validation:

d8:completei1e10:incompletei0e8:intervali120e12:min intervali120e5:peers0:6:peers60:e

Then verify scrape and global stats:

curl -sG "$BASE/scrape" --data-urlencode "info_hash=$INFO_HASH"
curl -s "$STATS"

Outputs captured during validation:

d5:filesd20:TTTTTTTTTTTTTTTTTTTTd8:completei1e10:downloadedi1e10:incompletei0eeee

{
  "torrents": 1,
  "seeders": 1,
  "completed": 1,
  "leechers": 0,
  "tcp4_connections_handled": 5,
  "tcp4_announces_handled": 2,
  "tcp4_scrapes_handled": 3,
  "tcp6_connections_handled": 0,
  "tcp6_announces_handled": 0,
  "tcp6_scrapes_handled": 0,
  "udp_requests_aborted": 0,
  "udp_requests_banned": 0,
  "udp_banned_ips_total": 0,
  "udp_avg_connect_processing_time_ns": 0,
  "udp_avg_announce_processing_time_ns" 
   
   
   
   
   
   
   
   
   
   
   
   
   

Expected meaning:

• scrape complete: 0 -> 1
• scrape downloaded: 0 -> 1
• scrape incomplete: 1 -> 0
• global seeders: 0 -> 1
• global completed: 0 -> 1

6. Browser option

You can open global stats directly in a browser:

http://127.0.0.1:1212/api/v1/stats?token=MyAccessToken

Use page refresh between steps to observe the counter changes.

Troubleshooting

If announce fails with peer-id validation, check peer-id length.

Example failure output captured during validation (peer_id had 21 bytes):

d14:failure reason269:Bad request. Cannot parse query params for announce request: invalid param value HTTPCLIENTPEERID00001 for peer_id in too many bytes for peer id: got 21 bytes, expected 20 ...e
