chore(test): add 2 tests reusing partial results

2026-08-31T06:26:32+00:00

Tests to show the socket isn't left in an undetermined state due to dataloss, since the partial results are returned to the user.

fix(receive): guard numeric pattern against size_t overflow on cast

2026-08-29T15:22:41+00:00

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.

fix(receive): guard maxsize against size_t overflow on cast

2026-08-29T15:22:29+00:00

Casting a double larger than SIZE_MAX to size_t is undefined behavior; bound-check maxsize before the cast.

feat(receive): add maxsize argument to bound memory usage

2026-07-30T20:06:04+00:00

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.

Changed buffer-per-socket to buffer-per-operation.

This is a difficult tradeoff to measure. I think large datagrams won't be used very frequently. So it is better to not lock a large buffer to each socket object and instead allocate and deallocate for each operation receiving a datagram larger than UDP_DATAGRAMSIZE.

Fixes suggested by @Florob in #147.

New agnostic IPv4 IPv6 functions.

2015-08-22T22:52:01+00:00

Also dealing with EPROTOTYPE Yosemite seems to be throwing at us for no reason.

New compat.h module implements luaL_setfuncs.

2015-08-21T18:39:34+00:00

Makes initialization code simpler everywhere.

Fix. Optional IPv6 test
