* fix(receive): a receive 0 should immediately return, not blockThijs Schreijer5 days1-10/+13
| | | | | | | | The fix is slightly more complex because reading from a closed socket should still return a closed-error. fixes: #427 fixes: https://github.com/ledgetech/lua-resty-http/pull/313
* fix(receive): guard numeric pattern against size_t overflow on castThijs Schreijer5 days1-1/+2
| | | | | | Same class of bug as the maxsize cast: a double larger than SIZE_MAX cast to size_t is undefined behavior. Bound-check the numeric receive pattern before the cast, and cover it with a test.

* feat(receive): add maxsize argument to bound memory usageThijs Schreijer2026-07-301-20/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | client:receive("*l") and receive("*a") are unbounded: a peer that never sends a newline, or never closes, makes LuaSocket buffer until the process runs out of memory (e.g. src/http.lua reading response headers in a loop). Add an optional maxsize argument that caps the payload a single call may accumulate, including prefix. - Hoist all argument validation ahead of timeout_markstart() so bad calls (maxsize < 1, #prefix >= maxsize, numeric pattern > maxsize) raise before any I/O and leave the socket untouched. - recvline/recvall take a budget and return a new internal BUF_OVERSIZED code, surfaced to Lua as the "oversized" error alongside "timeout"/"closed", with the partial held in the 3rd return value. - recvraw is left untouched: argument checks make the cap unreachable for numeric patterns. - Preserve three invariants: a timeout partial is always shorter than maxsize (safe to retry as prefix), completion beats the cap for *a, and no bytes are lost or skipped on overflow. - tcp.c, unixstream.c and serial.c all share this code path unchanged. Adds test coverage (argument errors, *l/*a boundaries, timeout/close at the cap, the drain idiom, numeric patterns, unix-stream mirror) and documents the new argument, error, and recovery idioms in docs/tcp.html.
