The call to 'luaL_newmetatable' in 'newbox' can leave an incomplete
metatable in the registry, if 'luaL_setfuncs' raises a memory error.
More permissive use of 'errno'2024-06-05T14:50:42+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-06-05T14:50:42+00:00urn:sha1:7eb1ed21b7057ab5f1b921f8271eddcf13659737
Assume that no function will put garbage on errno (although ISO C allows
that). If any function during an operation set errno, and the operation
result in an error, assume that errno has something to say.
Bug: luaL_traceback may need more than 5 stack slots2024-06-04T19:40:53+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-06-04T19:40:53+00:00urn:sha1:2db966fcbf757775c842bc66449d7e697826aa1dMore disciplined use of 'errno'2024-06-04T15:48:29+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-06-04T15:48:29+00:00urn:sha1:d5212c13b081ed62d8e1ae436779e79c79edf564
Set errno to zero before calling any function where we may use its
errno, and check errno for zero before using it (as functions may
not set it even in error).
Panic functions should not raise errors2023-11-24T19:08:55+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-11-24T19:08:55+00:00urn:sha1:842a83f09caa2ebd4bc03e0076420148ac07c808
The standard panic function was using 'lua_tostring', which may raise
a memory-allocation error if error value is a number.
Changed the growth rate of string buffers2022-09-06T13:58:55+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-09-06T13:58:55+00:00urn:sha1:69b77b6fde32cdf5dcaeeb92996bf6c4697e0b4f
The growth rate of string buffers was reduced from 2 to 1.5 (3/2).
As string buffers start larger (256~1024 bytes), they don't need to
grow that fast. Moreover, a lower rate allows multiplicative growth up
to larger sizes (3/2 of the maximum). (After that, the growth becomes
linear, which is mostly useless.)
Simpler handling of Byte Order Mark (BOM)2022-08-23T19:08:53+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-08-23T19:08:53+00:00urn:sha1:02060b7a37d88d4e92cf64a008c0651eae432c12Better documentation for 'multires' expressions2022-08-19T17:10:18+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-08-19T17:10:18+00:00urn:sha1:c6cea857a4845940c833e39a149d20bb64a9af85
Manual has a new section explaining multires expressions, lists of
expressions, and adjustments. This commit also corrects some comments
in the code.
Bug: luaL_tolstring may get confused with negative index2021-07-22T16:48:43+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-07-22T16:48:43+00:00urn:sha1:439e45a2f69549b674d6a6e2023e8debfa00a2b8
When object has a '__name' metafield, 'luaL_tolstring' used the
received index after pushing a string on the stack.
