https://git.lua4.win/lua/atom?h=v5.4.92026-07-22T17:42:55+00:00Bug: GC checks stack space before running finalizer2026-07-22T17:42:55+00:00Roberto Iroberto@inf.puc-rio.br2026-07-22T17:42:55+00:00urn:sha1:8511e90b7df5daf139aba290b9c9c1595927e7b3
If some stack does not have a minimum available space, the GC defers
calling a finalizer until the next cycle. That avoids errors while
running a finalizer that the programmer cannot control.
Bug: message handler can be overwritten2025-03-17T19:14:17+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-03-17T19:14:17+00:00urn:sha1:3fe7be956f23385aa1950dc31e2f25127ccfc0ea
A __close metamethod can overwrite a message handler in the stack
when closing a thread or a state.
Bug: 'luaD_seterrorobj' should not raise errors2025-03-12T19:01:03+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-03-12T19:01:03+00:00urn:sha1:25da574fcbb68bf507431a6091ab73ac434c9428
This function can be called unprotected, so it should not raise any
kind of errors. (It could raise a memory-allocation error when creating
a message).
More disciplined use of 'getstr' and 'tsslen'2023-08-17T18:59:28+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-08-17T18:59:28+00:00urn:sha1:9b4f39ab14fb2e55345c3d23537d129dac23b091
We may want to add other string variants in the future; this change
documents better where the code may need to handle those variants.
Several functions turned 'static'2023-05-22T17:47:54+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-05-22T17:47:54+00:00urn:sha1:9be74ccc214eb6f4d9d0b9496fd973542c7377d9
Several functions that were already being used only inside their
own file have been declared as 'static'.
"Emergency" new version 5.4.62023-05-02T19:41:43+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-05-02T19:41:43+00:00urn:sha1:6443185167c77adcc8552a3fee7edab7895db1a9
'lua_resetthread' is back to its original signature, to avoid
incompatibilities in the ABI between releases of the same version.
New function 'lua_closethread' added with the "correct" signature.
Threads are created like other objects2022-11-01T20:14:01+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-11-01T20:14:01+00:00urn:sha1:9ede317c70ad82279f2e3962eb52904a17bf4b55
Using a version of 'luaC_newobj' that allows offsets (extra space
before the object itself).
Stack indices changed to union's2022-10-29T15:06:37+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-10-29T15:06:37+00:00urn:sha1:413a393e6222482f46599e138bebac162610a572
That will allow to change pointers to offsets while reallocating
the stack.
Bug: stack overflow with nesting of coroutine.close2022-10-25T19:44:06+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-10-25T19:44:06+00:00urn:sha1:1e64c1391f9a14115b5cc82066dbf545ae73ee27Bug: GC is not reentrant2021-12-13T13:41:17+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-12-13T13:41:17+00:00urn:sha1:0bfc572e51d9035a615ef6e9523f736c9ffa8e57
As the GC is not reentrant, finalizers should not be able to invoke it.
