Testing & Quality
View on GitHub

Manual end-to-end verification of started -> completed peer lifecycle using the HTTP tracker announce/scrape endpoints with curl (or browser for stats). Use when contributors want a fast, transparent simulation of download completion without containerized clients. Triggers on "manual http e2e", "http announce completed test", "simulate completion with curl", or "verify completed counter http".

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.

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

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
