The union may have alignment requirements stricter than some of its
members. Some checking tools (e.g., gcc with options -fsanitize) can
then complain that the result of a cast from pointer to member to
pointer to the union is misaligned.
More effort in avoiding errors in finalizers2026-01-11T18:36:03+00:00Roberto Iroberto@inf.puc-rio.br2026-01-11T18:36:03+00:00urn:sha1:2a7cf4f319fc276f4554a8f6364e6b1ba4eb2ded
Before calling a finalizer, Lua not only checks stack limits, but
actually ensures that a minimum number of slots are already allocated
for the call. (If it cannot ensure that, it postpones the finalizer.)
That avoids finalizers not running due to memory errors that the
programmer cannot control.
Removed code for compatibility with version 5.32025-08-20T19:10:54+00:00Roberto Iroberto@inf.puc-rio.br2025-08-20T19:10:54+00:00urn:sha1:06c5d3825f03eafc90b56d43f70f70048b785bc8Detail in 'obj2gco'2025-08-20T17:18:12+00:00Roberto Iroberto@inf.puc-rio.br2025-08-20T17:18:12+00:00urn:sha1:c688b00f73205273c46d7cf5656ff5a27e90ce36
Its check should use the type of the object, not its tag. (Change only
relevant in test mode.)
Correction in definition of CIST_FRESH2025-07-07T18:03:45+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-07-07T18:03:45+00:00urn:sha1:848568790826b7e201f84682185b5b605c473016
The cast must be made before the shift. If int has 16 bits, the shift
would zero the value and the cast would cast 0 to 0.
'lua_State.nci' must be an integer2025-02-26T14:31:10+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-02-26T14:31:10+00:00urn:sha1:f9e35627ed26dff4114a1d01ff113d8b4cc91ab5
Lua can easily overflow an unsigned short counting nested calls.
(The limit to this value is the maximum stack size, LUAI_MAXSTACK,
which is currently 1e6.)
Main thread is a regular field of global_State2025-01-31T16:51:38+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-01-31T16:51:38+00:00urn:sha1:fa1382b5cd504bdfc5fc3f5c447ed09a4c9804fd
They were already allocated as a single block, so there is no need
for the global_State to point to its main thread.
New type 'TStatus' for thread status/error codes2025-01-30T14:41:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-01-30T14:41:39+00:00urn:sha1:d1e677c52be3b107a7a29fdc482158f6d9251e79CallInfo bit CIST_CLSRET broken in two2025-01-28T14:45:45+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-01-28T14:45:45+00:00urn:sha1:39a14ea7d7b14172595c61619e8f35c2614b2606
Since commit f407b3c4a, it was being used for two distinct (and
incompatible) meanings:
A: Function has TBC variables (now bit CIST_TBC)
B: Interpreter is closing TBC variables (original bit CIST_CLSRET)
B implies A, but A does not imply B.
