The inner transport therefore still pooled idle connections across requests on the same client instance — so the flag only avoided cross-test client reuse, not stale-conn races within a single test. Plumb the flag end-to-end: - Add Browser.DisableKeepAlives (client.go) — Browser is the boundary the flag flows through into newRoundTripper. - Add roundTripper.DisableKeepAlives, set in newRoundTripper from the Browser field. - Bind all 4 http.Transport literals in roundtripper.go to rt.DisableKeepAlives instead of the hardcoded false. - In getOrCreateClient: when enableConnectionReuse=false, set browser.DisableKeepAlives = true before constructing the client. Default behaviour is preserved: when the flag is absent or true, DisableKeepAlives ends up false on every transport, exactly as before. Tests: golang/roundtripper_test.go pins propagation through Browser → roundTripper, exercises the HTTP-scheme transport via getTransport, and asserts the source-level invariant that no DisableKeepAlives: false hard binding remains. * ci: re-trigger after rebase on slim-matrix main * ci: trigger after base change to main * ci: re-trigger after rebase on action-bumps main --- golang/client.go | 21 +++++++++-- golang/roundtripper.go | 15 +++++--- golang/roundtripper_test.go | 70 +++++++++++++++++++++++++++++++++++++ 3 files changed, 100 insertions(+), 6 deletions(-) diff --git a/golang/client.go b/golang/client.go index f91189c..edd98a8 100644 --- a/golang/client.go +++ b/golang/client.go @@ -94,6 +94,14 @@ type Browser struct { ForceHTTP1 bool ForceHTTP3 bool + // DisableKeepAlives, when true, disables HTTP keep-alives at the + // inner http.Transport layer for every request that uses this Browser. + // Set this when the caller passes enable_connection_reuse=false from + // Python so that connection reuse really is disabled — bypassing the + // global client cache alone is not sufficient because the underlying + // transport otherwise still pools idle connections per address. + DisableKeepAlives bool + // TLS 1.3 specific options TLS13AutoRetry bool @@ -243,10 +251,19 @@ func generateClientKey(browser Browser, timeout int, disableRedirect bool, proxy return key } -// getOrCreateClient retrieves a client from the pool or creates a new one +// getOrCreateClient retrieves a client from the pool or creates a new one. +// +// When enableConnectionReuse is false the caller wants no connection reuse +// at all, so we both bypass the global client pool *and* propagate +// DisableKeepAlives onto the Browser.

Replacing them with the proper types lets utls own the wire encoding (including any future bugfixes) and removes hand-rolled byte payloads: - ID 17 (status_request_v2): GenericExtension -> StatusRequestV2Extension (proper RFC 6961 encoding instead of zero-length GenericExtension) - ID 17613 (TLS ALPS new codepoint): GenericExtension -> ApplicationSettingsExtensionNew Hand-rolled 5-byte payload {0x00,0x03,0x02,0x68,0x32} replaced by SupportedProtocols-driven encoding identical to ID 17513. - ID 30032 (Channel ID): GenericExtension(Id:0x7550, Data:{0}) -> FakeChannelIDExtension{}. Wire format also corrected: real Chrome ChannelID is a 4-byte zero-payload extension, the previous GenericExtension emitted 5 bytes (length=1). ID 51 (KeyShare), ID 43 (SupportedVersions), IDs 10/11 (curves/points) remain populated by callers because they depend on per-call inputs (version, GREASE flag, JA3 curves). ID 65037 (GREASE_ECH) is already correctly using utls.BoringGREASEECH().

The Go transport (loaded as a shared library) caches TLS connections in a global pool; the next test reuses the already-closed connection, causing "use of closed network connection". Setting enable_connection_reuse=False per request forces a fresh roundTripper with empty cachedConnections, matching how the blocking tests already work. * fix: handle TrackMe HTTP/2 POST rejection and unpatched clients in live tests - test_post_method: TrackMe rejects non-GET via HTTP/2 RST_STREAM causing timeout; skip gracefully instead of failing - test_multiple_clients: explicitly pass enable_connection_reuse=False since these clients are created directly in the test body, bypassing the fixture wrapper * test: mark external-resource tests as live; add Python matrix to live CI Move test files that hit tls.peet.ws / scrapfly.io to the live test suite by adding `pytestmark = pytest.mark.live`, so they no longer run in the unit-test workflow (which has no network access to those endpoints). Expand the live-tests workflow to a Python 3.10–3.13 matrix (ubuntu-only, since TrackMe requires Docker) matching the breadth of the unit-test matrix. Affected test files: - test_async_ja3.py - test_force_http1.py - test_frame_headers.py - test_http2.py - test_http2_fingerprint.py - test_integration.py - test_ja3_fingerprints.py - test_ja4_fingerprints.py * fix: apply _no_reuse pattern to all live test fixtures hitting TrackMe TrackMe closes the TLS connection after every response. The global Go transport caches the closed connection; the next test gets "use of closed network connection". Fix by injecting enable_connection_reuse=False via setdefault in: - conftest.py cycletls_client (covers test_integration, test_http2_fingerprint, test_tls13) - test_force_http1.py client fixture - test_http2.py cycle fixture - test_ja3_fingerprints.py cycle_client fixture - test_ja4_fingerprints.py cycle_client fixture - test_async_ja3.py: add enable_connection_reuse=False to 5 individual requests that were missing it (async tests can't use the wrapper pattern) * refactor(tests): rename TRACKME_URL env var to TLSFP_URL Tests now read the local-server endpoint from TLSFP_URL instead of the TrackMe-specific TRACKME_URL. Default remains https://tls.peet.ws so local devs without the local server still hit production. The renamed fixture (trackme_url -> tlsfp_url) and updated docstrings reflect that the local target is Danny-Dasilva/tlsfingerprint.com (the source of tls.peet.ws), not the third-party TrackMe image. * ci(tests): launch Danny-Dasilva/tlsfingerprint.com Docker container for live tests Replaces the third-party TrackMe Docker setup that this PR originally added with the user's own tlsfingerprint.com server (the open-source code that powers tls.peet.ws). Both blocking-tests and live-tests workflows now: 1. Check out Danny-Dasilva/tlsfingerprint.com@master into .tlsfingerprint-server/ 2. Generate a self-signed cert via openssl 3. Patch config.example.json to disable mongo/log_to_db 4. Build + start the container via the upstream docker-compose.yml (NET_ADMIN/NET_RAW caps, ports 80/443/443-udp) 5. Wait up to 90s for /api/clean to respond 6. Inject TLSFP_URL=https://localhost and SSL_CERT_FILE so tests trust the self-signed cert and target the local server 7. Tear the container down at the end of the run Tests still fall back to https://tls.peet.ws when TLSFP_URL is unset, so local developers without Docker keep working against production. Adds tests/README.md documenting the local-dev path and test markers. * ci: re-trigger after rebase on slim-matrix main * ci: re-trigger * ci: re-trigger after rebase on action-bumps main * test(ja4): match JA4_r structurally to handle production vs local server padding * test(blocking): apply JA4_r structural matcher to test_tlsfingerprint_blocking too The previous commit (7ad1723) only patched tests/test_ja4_fingerprints.py. The blocking test module (tests/test_tlsfingerprint_blocking.py) still contained 5 exact-equality JA4_r assertions, including test_ja4r_tls12_fingerprint_exact_match which was the actual CI failure (production tls.peet.ws emits 't12d128h2' for 12 ciphers + 8 extensions unpadded; the local tlsfingerprint.com Docker emits the spec-padded 't12d1208h2'; equality fails). Promote parse_ja4r and assert_ja4r_equivalent helpers from test_ja4_fingerprints.py into tests/conftest.py as public names so they can be reused. Both test files now import from conftest. Replace the five JA4_r equality assertions in test_tlsfingerprint_blocking.py with structural matcher calls. * test: scope _no_reuse to TLSFP_URL so httpbin tests keep keep-alive The session-wide `enable_connection_reuse=False` wrapper was forcing fresh TLS handshakes for *every* request, including ones against httpbin.org. httpbin closes idle HTTP/1.1 connections aggressively, so disabling reuse there causes "server closed idle connection" / EOF errors on multi-request flows like: - test_http1_with_cookies (set cookie -> get cookie) - test_http1_with_redirects (redirect chain) These two tests fail consistently across all 4 Python versions in the Live Tests workflow. Fix: only force `enable_connection_reuse=False` when the URL is the local tlsfingerprint.com server (TLSFP_URL). Public endpoints (httpbin.org) keep the default keep-alive behaviour. --------- Co-authored-by: Stefan Meinecke --- .github/workflows/blocking-tests.yml | 41 +++++ .github/workflows/live-tests.yml | 52 +++++- .gitignore | 3 + tests/README.md | 60 +++++++ tests/conftest.py | 162 +++++++++++++++++- tests/integration/test_api.py | 11 +- tests/test_async_ja3.py | 54 +++--- tests/test_force_http1.py | 27 ++- tests/test_frame_headers.py | 29 ++-- tests/test_http2.py | 18 +- tests/test_http2_fingerprint.py | 14 +- .../test_http2_fingerprint_tlsfingerprint.py | 31 +++- tests/test_integration.py | 15 +- tests/test_integration_tlsfingerprint.py | 56 ++++-- tests/test_ja3_fingerprints.py | 50 ++++-- tests/test_ja3_fingerprints_tlsfingerprint.py | 43 +++-- tests/test_ja4_fingerprints.py | 152 ++++++++++------ tests/test_ja4_fingerprints_tlsfingerprint.py | 31 +++- tests/test_module_api.py | 12 +- tests/test_tls13.py | 14 +- tests/test_tlsfingerprint_blocking.py | 54 +++--- 21 files changed, 721 insertions(+), 208 deletions(-) create mode 100644 tests/README.md diff --git a/.github/workflows/blocking-tests.yml b/.github/workflows/blocking-tests.yml index cca0d67..2d37d18 100644 --- a/.github/workflows/blocking-tests.yml +++ b/.github/workflows/blocking-tests.yml @@ -40,5 +40,46 @@ jobs: - name: Install dependencies run: uv sync --locked --all-extras --dev + - name: Checkout Danny-Dasilva/tlsfingerprint.com + uses: actions/checkout@v4 + with: + repository: Danny-Dasilva/tlsfingerprint.com + ref: master + path: .tlsfingerprint-server + + - name: Generate TLS certificates and config + working-directory: .tlsfingerprint-server + run: | + mkdir -p certs + openssl req -x509 -newkey rsa:4096 \ + -keyout certs/key.pem \ + -out certs/chain.pem \ + -sha256 -days 365 -nodes \ + -subj "/CN=localhost" \ + -addext "subjectAltName=IP:127.0.0.1,DNS:localhost" + jq '.log_to_db = false | .mongo_url = "" | .device = ""' \ + config.example.json > config.json + cat /etc/ssl/certs/ca-certificates.crt certs/chain.pem > /tmp/combined-test-cas.crt + + - name: Build and start tlsfingerprint.com server + working-directory: .tlsfingerprint-server + run: | + docker compose up -d --build + echo "Waiting for tlsfingerprint.com server to become ready..." + if ! timeout 90 bash -c 'until curl -sk --max-time 3 https://localhost/api/clean -o /dev/null; do sleep 2; done'; then + echo "Server did not become ready in time.

Do() silently dropped ServerName, TLS13AutoRetry, and DisableGrease when building the Browser struct. These fields were added to processRequest() in upstream commits 36f5171 (Draft Release #400, adds ServerName+TLS13AutoRetry) and a483b68 (Release 2.0.4 #390, adds DisableGrease) but were never propagated to Do(). 2. dispatchSSEAsync used bare `break` inside `for { select { ... } }`, which only breaks out of the select, not the outer loop — causing an infinite spin on context cancellation, EOF, or read errors. Introduced in upstream 5990fef (Major Release 2.0.0 #387). Fixed by adding a `sseLoop:` label and using `break sseLoop`. * fix(go): preserve JA3 supported_groups in TLS13AutoRetry proactive upgrade convertJA3ForTLS13 was hard-coding tokens[3] = "29-23", silently dropping P-384 (24), P-521 (25), FFDHE2048 (256), FFDHE3072 (257) and any other groups from the JA3 string before the first handshake attempt. This made TLS13AutoRetry (enabled by default) corrupt the fingerprint being applied. Fix: filter the groups field using isTLS13CompatibleCurve() instead of replacing it, preserving all RFC 8446 §4.2.7 compatible NamedGroups in their original order. Also extend isTLS13CompatibleCurve() to include FFDHE groups (256-260) which are valid TLS 1.3 NamedGroups per RFC 7919 and are advertised by Firefox/Safari in the supported_groups extension. * docs+test: document local_address in api.py kwargs; add schema, validation and live tests * docs(changelog): note Go core fixes from #65 * fix(go-core): apply localAddress to SOCKS/HTTPS-proxy/HTTP3 dial paths The PR #40 / #65 localAddress implementation silently dropped the local-IP bind on three proxy/transport paths. This change closes those gaps so the LocalAddr the user provided actually controls the kernel-level bind on the client->proxy socket on every supported scheme. Gaps addressed (identified in the code-trace and network-research reports at .claude/cache/agents/{code-trace,network-research}-localaddress-proxy): 1. SOCKS proxies (connect.go) The localAddress -> baseDialer block ran AFTER the scheme switch's socks5/socks5h/socks4 early returns, so the SOCKS dialers never saw LocalAddr. baseDialer is now built before the switch and: - socks5/socks5h: passed as the forward Dialer to proxy.SOCKS5, so the TCP-to-proxy connect honors LocalAddr. - socks4: when localAddress is set, h12.io/socks (which always uses net.DialTimeout internally with no LocalAddr hook) is bypassed via a small in-package socks4ContextDialer that performs the CONNECT handshake over a baseDialer.DialContext'd conn. With localAddress unset, the existing h12.io/socks path is preserved verbatim. 2. HTTPS proxies (connect.go) The default TLS-to-proxy step used tls.Dial(network, addr, &tlsConf), which bypasses any custom net.Dialer and silently dropped LocalAddr. Replaced with c.tlsDialer.DialContext (LocalAddr-aware) followed by tls.Client + HandshakeContext so the bind takes effect on the client->HTTPS-proxy TCP socket. 3. HTTP/3 / QUIC (http3.go) net.ListenPacket("udp", "") ignored localAddress entirely. Threaded LocalAddress through Browser -> roundTripper -> http3Dial; when set, the UDP socket is bound to :0. Empty localAddress preserves the prior kernel-chooses behavior. Also expands the cycleTLSRequestOptions.LocalAddress field comment to document that, when a Proxy is in the path, the bind applies to the client->proxy hop only — the proxy host always sees this IP, but the destination server never does. This is routing/interface control, not an anonymizer against the proxy itself. Verified: go build ./..., go vet ./...

- version-conditional equivalent; slots are still used on Python 3.10+ - - `_batcher.py`: removed `zip(..., strict=True)` (Python 3.10+); the - length mismatch is already guarded by an explicit check above the loop - - Dev dependencies: added Python-version-conditional variants for - `pytest` and `pytest-asyncio` so the lock file resolves on Python 3.9 - - CI: added Python 3.9 to the unit-test and live-test matrices +- `local_address` parameter to bind outgoing TCP connections to a specific local IP for outbound interface/IP selection (#65) + +### Fixed +- `Do()` dropped `ServerName`, `TLS13AutoRetry`, and `DisableGrease` request fields when constructing the underlying request (#65) +- `TLS13AutoRetry` proactive upgrade corrupted JA3 `supported_groups`; the original JA3 ordering is
