Verify the static hosts mapping (HostMapper) overrides DNS: a mapped
hostname resolves to the configured IP and reaches the echo server,
while an unmapped hostname fails to resolve.
Verify HTTP proxy authentication for both inline single-user auth and a
named auther with multiple users. Covers valid credentials, wrong
password, missing credentials, and any-user-in-auther acceptance.
Verify service-level admission control gating by client source IP, in
both whitelist and blacklist modes. Contrasts a loopback client (curl
inside the gost container) against an external client (curl inside the
echo container) to exercise both admit and deny paths.
Verify both blacklist and whitelist bypass modes: a matching destination
skips the dead chain node and connects directly to the echo server, while a
non-matching destination is forced through the dead node and never reaches it.
Merge parallel_selector_test.go into selector_test.go and add e2e coverage
for the round-robin + fail filter, fifo sticky fallback, and backup filter
strategies. Each test drives requests through a hop with one dead node and
asserts the selector marks and skips it so traffic converges on the live node.

Add tests/e2e/http2_test.go covering the http2 handler/listener/connector/dialer
end-to-end through the canonical gost-as-client pattern (8 subtests: forward,
auth, bypass, probeResist/metadata, h2 stream multiplexing). Include
testdata/http2/{server,server_auth,server_bypass,server_proberesist,client,
client_auth}.yaml. Note that h2/h2c listeners pair with the tunnel handler
and only http2 listener pairs with handler http2 (reads r/w from metadata).
Tighten TestDNSHostMapper by pointing the handler at an unreachable upstream
so unmapped names fail at the exchanger, confirming the host-mapper path was
the sole reason mapped names resolved. Fix http_idle_timeout.py to speak HTTP
through the CONNECT tunnel rather than a raw ping, matching the echo backend.

Adds 22 DNS e2e subtests across 8 test methods covering: upstream
resolution (A, AAAA, multi-A), TCP mode, bypass rules, host mapper,
exchange failure (graceful error recovery), rate limiter wiring,
invalid query handling, and DNS over TLS (mode: tls).
Includes two authoritative DNS responders (UDP/TCP), a standalone
DNS query client, and a TLS DNS query script.
Adds 5 test methods (7 test cases) for the file handler:
GET existing file, GET nonexistent file, GET index.html, PUT upload,
PUT without permission, and auth (no-auth-401, with-auth-success).
Includes test data files and server YAML configs under
tests/e2e/testdata/file/.
Adds 12 new HTTP handler test scenarios: HTTP connector (no-auth, auth, TLS
upstream), CONNECT tunnel (no-sniffing, bypass-403), probeResist (host, web,
file, knock), idleTimeout, and UDP relay over HTTP. Introduces
RunGostContainerWithFiles helper for mounting extra files into test containers.
- Replace bare int with atomic.Int32 to fix data race on ret
- Replace wg.Add/go/defer wg.Done pattern with wg.Go (Go 1.22+)
- Pass context by value instead of pointer
- Add ctx.Err() guard to suppress fatal on cancellation errors
- Add ProcessState nil check before accessing ExitCode
- Move cancel() after wg.Wait() to avoid race where a successful
worker's deferred cancel kills siblings and triggers log.Fatal
Move xmetrics.Enable(true) from run() to Start(), before loader.Load(),
so that listener wrappers can observe the enabled state at Init time
rather than after wrapper decisions have already been made.
Introduce -R <duration> flag (e.g., -R 30s, -R 1m) that triggers
periodic config reload. Combined with -C URL support, this enables
centralized fleet management where nodes poll a remote config server.
The reload goroutine reuses the existing SIGHUP reloadConfig path:
parser.Parse() → loader.Load() → p.run(cfg). When -R is zero
(default) behavior is unchanged; SIGHUP still works independently.
Docker-in-Docker containers cannot reach the internet via the default
bridge network, causing 'apk add' in the Dockerfile to hang indefinitely
and e2e tests to timeout after 10 minutes.
Add BuildOptionsModifier with NetworkMode=host to all FromDockerfile
definitions so the build step uses the host's network stack. This has
no negative impact on non-DinD environments where bridge networking
already works.
Also move GostBinPath flag and init() from main_test.go to utils.go
(non-test file) so the symbol is accessible across the package.
UPX --best/--lzma/--brute adds ~3s startup time on low-spec systems
(linux/arm) due to in-memory decompression on every invocation of gost -V.
Disabled by default; opt in via GORELEASER_UPX=true for release builds
that need it.
