Clash and v2ray set ALL_PROXY=socks5h://..., which ureq reads before
HTTPS_PROXY. Enable the socks-proxy feature so that entry is used instead
of skipped, and cover a socks5h tunnel with a fake SOCKS5 server.
ureq is built without socks-proxy, so an ALL_PROXY=socks5h entry failed
every request and a socks5 entry silently connected directly, while also
suppressing the Windows system proxy. Pick the first HTTP or HTTPS proxy
from the environment ourselves, keep NO_PROXY on it, and fall back to the
system proxy when none is usable.
Replace the WinHTTP client with a ureq agent that keeps the same
Client/Response surface: status errors come back as responses, gzip,
60 s connect / 30 s receive / 120 s total timeouts, rustls with the
platform verifier and a per-request User-Agent override.
Environment proxies come from ureq. On Windows, when none is set, the
static Internet Settings proxy is read from HKCU and parsed by a pure
core module (per-scheme ProxyServer, ProxyOverride globs and <local>);
bypassed hosts go through a direct agent. PAC/WPAD is not evaluated.
The usage providers and credential sources compile again on every
platform. Refresh keeps the Windows candidates and CREATE_NO_WINDOW;
Unix spawns claude/codex from PATH plus the usual per-user install
directories and reaps the child on a detached thread. An empty
CODEX_HOME now counts as unset and a float expiresAt is truncated
instead of ignored.
Fixture tests cover the OAuth usage body, rate-limit headers (including
a 429 over loopback), the ChatGPT envelope, ISO 8601 edge cases,
credential JSON and proxy strings. An ignored live_poll test polls the
real providers.
