Second-pass on the SOCKS5 inbound scaffold (PR #4452). This commit
ticks off two of the 'help wanted' items from the scaffold's TODO
list and tightens the existing dispatcher so that adding a new
protocol-without-link in the future is a one-line change instead
of an audit through every switch.
Backend (Go)
------------
* database/model/model.go: new IsSocksLike(p) helper that returns
true for both 'socks' and 'mixed'. Mirrors the existing IsHysteria
pattern (one helper, two underlying constants) so call sites
don't have to re-list both protocols every time they need to
treat 'this inbound speaks SOCKS5' uniformly.
* database/model/model_test.go:
- TestSocksProtocolConstant pins the wire value 'socks' so a
future refactor can't silently rename it (which would orphan
every stored inbound row).
- TestIsSocksLike covers Socks, Mixed, every other declared
protocol, the empty Protocol, and a wrong-case input.
* sub/subService.go GetLink:
- Replace bare string literals ('vmess', 'vless', …) with the
typed model.* constants so a typo can't silently fall through.
- Add an explicit link-less case for
Socks/Mixed/HTTP/Tunnel/WireGuard with a comment explaining
why we don't emit 'socks://…' URLs (follow-up #1 in the
scaffold PR description).
Frontend (JS/Vue)
-----------------
* frontend/src/models/dbinbound.js: add 'isSocks' getter (pure
SOCKS5 inbound) and 'isSocksLike' getter (Socks OR Mixed), matching
the pattern used by isMixed/isHTTP/isWireguard above.
* frontend/src/pages/inbounds/InboundInfoModal.vue: the existing
'Mixed' info block (auth/UDP/IP/accounts) now also renders for
the new SOCKS protocol via isSocksLike, since Xray's mixed and
socks inbounds accept the exact same settings keys. Without
this, opening the info modal for a SOCKS inbound would show an
empty body. Header comment updated to list SOCKS alongside
Mixed/HTTP/Tunnel.
Still outstanding from the scaffold's TODO list:
- Xray runtime AddUser hooks (web/service/inbound.go)
- Translations for the 'socks' label across all 13 locales
- Routing UI protocol == socks helper
UI stores v1 and v2 both as "hysteria" with settings.version, but
inbounds that came in from imports / manual SQL can carry the
literal "hysteria2" string and get silently dropped everywhere we
switch on protocol.
Add Hysteria2 constant + IsHysteria helper, use it in the places
that gate on protocol (sub SQL, getLink, genHysteriaLink, clash
buildProxy, json gen, inbound.go validation, xray AddUser).
Existing "hysteria" inbounds are untouched.
