Remove dead null checks, document CLOAKBROWSER_GEOIP_TIMEOUT_SECONDS
env var, credit contributor.
Fix review findings:
- Use timeout-bounded resolve_proxy_exit_ip in _resolve_webrtc_args
- Add missing timeout handler on tunneled HTTPS request in JS
- Reject nan/inf in Python timeout parsing (parity with JS)
- Recompute deadline after CONNECT succeeds in JS proxy tunnel
* fix(proxy): log when SOCKS5 credential auto-encoding rewrites URL (#157)
Auto URL-encoding of SOCKS5 credentials (added in v0.3.26 to fix Chromium's
'=' truncation bug) currently happens silently. Users debugging connectivity
have no way to know the wrapper rewrote their proxy URL — the original #157
thread took 8 round-trips to surface this exact ambiguity.
Emit a log when re-encoding actually changes the URL: INFO on Python's
'cloakbrowser' logger, console.debug in JavaScript. Stays silent on
already-encoded inputs and credential-less URLs to avoid false-positive
noise. Credentials are not included in the log message.
Tests: 3 new cases per language (Python caplog, JS vi.spyOn console.debug)
covering trigger / silent-when-encoded / silent-when-no-creds.
* fix(proxy): gate log on credential change, not full URL diff
Per Copilot review on #209: urlparse cosmetically lowercases scheme and
hostname, so comparing the full reconstructed URL to the input would emit
"Auto URL-encoded SOCKS5..." even for inputs like
`socks5://USER:pass@HOST.com:1080` where no credential encoding happened.
Compare raw vs encoded user/password substrings instead. Mirror the same
condition in JS for parity (JS's manual parser preserves case today, but the
credential-level compare is more robust against future changes).
Adds one regression test per language.
The humanize layer hardcoded timeout=2000ms for element lookups, causing
locator.click() and page.click() to fail instantly instead of retrying
for 30s like standard Playwright. Aligned all defaults to 30000ms across
Python sync/async, JS Playwright, and JS Puppeteer paths. Bumped the
outer retry sleep from 200ms to 500ms for DOM mutation settle time.
Chromium's --proxy-server parser truncates passwords at '=' and other
special chars, causing SOCKS5 auth to silently fail and fall back to
direct connection. The dict path already encoded creds; now the string
path does too. Idempotent: pre-encoded input stays encoded.
Python: add async counterpart to launch_context(). Forwards all kwargs to
browser.new_context() — enables storage_state, permissions, extra_http_headers,
etc. without needing a persistent profile folder.
JS: launchContext() and launchPersistentContext() silently dropped unknown
options. New contextOptions field in LaunchContextOptions is spread into
newContext() to forward arbitrary Playwright context options (e.g.
storageState, permissions, geolocation).
Route SOCKS5/SOCKS5h proxies via --proxy-server Chrome arg instead of
Playwright's proxy dict (which rejects SOCKS5 with credentials).
Handles string URLs, Playwright dicts, IPv6, bypass lists.
SOCKS5 geoip exit IP resolution uses socks-proxy-agent (optional peer
dep). Falls back to DNS if not installed.
Remove --disable-blink-features=AutomationControlled (dead, binary handles
navigator.webdriver at source level) and hardcoded GPU vendor/renderer flags.
Binary auto-generates diverse GPU profiles from fingerprint seed. Improves
fingerprint diversity -- previously every user shared the same GPU string.
Bump to v0.3.21.
viewport=None now disables viewport emulation via Playwright's
no_viewport=True, matching the JS wrapper's viewport: null behavior.
Uses a sentinel to distinguish "not provided" from explicit None.

Two ways to spoof WebRTC ICE candidate IPs:
1. --fingerprint-webrtc-ip=auto in args: resolves proxy exit IP via
HTTP call through the proxy (ipify.org). No extra deps needed.
2. geoip=True: auto-injects the flag for free (exit IP already
resolved during timezone/locale lookup, zero extra network cost).
Explicit IP (--fingerprint-webrtc-ip=1.2.3.4) also supported.
User-provided values always take precedence.
Python + JS wrappers, README docs, tests.
Spawns a separate Chrome process per unique fingerprint seed, all behind
a single port (9222). Clients specify seeds and fingerprint params via
query string on the CDP URL:
connect_over_cdp("http://host:9222?fingerprint=12345&timezone=Asia/Tokyo")
Supports all --fingerprint-* flags as query params, geoip=true for
auto timezone/locale from proxy IP, and proxy= for per-process proxies.
- Rewrite bin/cloakserve from 57-line wrapper to aiohttp CDP multiplexer
- Add ChromePool with per-seed process management and port allocation
- Bidirectional WebSocket proxy for CDP traffic
- URL rewriting for /json/version, /json/list, and WS paths
- Rename _build_args -> build_args, _maybe_resolve_geoip -> maybe_resolve_geoip
- Add aiohttp + websockets to serve optional deps
- Dockerfile installs .[serve] extras
- Add 20 unit tests for cloakserve (param parsing, CLI args, URL rewriting)
- Bump wrapper version to 0.3.17 (Python + JS)
- Update PLATFORM_CHROMIUM_VERSIONS: windows-x64 109.2 → 159.7
- Update patch counts in platform tables (Linux 33, Windows 33)
- Add Linux arm64 to JS README platform table
- Update CHANGELOG with all changes since v0.3.16
Headed mode (all platforms): Chromium's GPU blocklist disables WebGL on
software GPUs in Docker/VNC/Xvfb. Flag lets SwiftShader serve WebGL.
Harmless on real GPUs. Headless unaffected. Ref #56.
Windows (all modes): GPU blocklist also blocks WebGPU for the Microsoft
Basic Render Driver. Dawn's adapter_blocklist bypass alone isn't enough.

Adds install, info, update, and clear-cache subcommands with visible
download progress. Python: `python -m cloakbrowser install`. JavaScript:
`npx cloakbrowser install`. Useful for Dockerfiles where silent
first-use downloads are hard to debug. Closes#43.

guard console.debug behind DEBUG=cloakbrowser env var, strengthen caplog assertion.

Replaces logger.info() calls that were invisible by default.
Bump to v0.3.8.
- Rename timezone_id → timezone in launch_context(), launch_persistent_context(),
and launch_persistent_context_async() (Python)
