🚀 Xray-knife v11.2.0 (JOIN THE TELEGRAM CHANNEL)

https://t.me/lilendian0x00

Deduplication was quietly eating good configs, and subscription fetching now has limits you control. 🛠️

✅ Nothing breaks. No flags moved, no names changed — upgrade and carry on.

🕳️ Dedup dropped configs that weren't duplicates

xray-knife http -f deduplicates by connection identity (--dedup-semantic, on by default). The identity it built ignored fields that decide which server you actually reach:

• 🔑 REALITY public key (pbk) — different REALITY servers looked identical
• 👤 SOCKS / Shadowsocks username and password — two accounts on one host collapsed into one
• ❓ any parameter the parser didn't already know about

A list of REALITY configs sharing one host:port could shrink to a single entry, and the rest were never tested. 😬

Semantic dedup removed 49 duplicate config link(s). Testing 1 unique configs.

Identity is now a SHA-256 over the whole parsed link minus the #remark — unknown options included. Re-skinned duplicates still collapse; distinct configs survive.

📥 Subscription fetching is bounded

A subscription used to be read with no ceiling: whole body into memory, no deadline on the read. A small gzip response that expanded to gigabytes took the process with it. 💥

Per source, defaults are 64 MiB, 100,000 links and 30s. Raise them when you need to:

xray-knife subs fetch --all --max-bytes 134217728 --max-links 200000 --fetch-timeout 2m

• 🗜️ the size limit applies after decompression
• ⏱️ the timeout covers the body read, not just the connect
• 🧾 a malformed body now fails loudly instead of returning half a list

🧩 New: pkg/subscription for Go programs

Fetching and decoding moved into a standalone package — no CLI flags, no database, no globals. Bring your own http.Client, context and limits:

res, err := subscription.Fetch(ctx, client, url, subscription.FetchOptions{})

core.ConnectionFingerprint(core, link) is exported alongside it, so you can dedupe against your own storage with the same identity the tester uses.
