When both 'int' and 'l_obj' have 32 bits, an unsigned int needs a
cast to be assigned to 'l_obj'. (As long as 'l_obj' can count the
total memory used by the system, these casts should be safe.)
Randomness added to table length computation2025-07-18T19:18:30+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-07-18T19:18:30+00:00urn:sha1:303f4155593721dfd57dadc6e56122e465ce9efb
A bad actor could fill only a few entries in a table (power of twos in
decreasing order, see tests) and produce a small table with a huge
length. If your program builds a table with external data and iterates
over its length, this behavior could be an issue.

'l_uint32' is enough for unicode codepoints (versus unsigned long),
and the utf-8 library already uses that type.

Comments, small changes in the manual, an extra test for errors in
error handling, small changes in tests.
Fixed conversion warnings from clang2025-01-14T19:24:46+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2025-01-14T19:24:46+00:00urn:sha1:3cdd49c94a8feed94853ba3a6adaa556fb34fd8d
Plus some other details. (Option '-Wuninitialized' was removed from
the makefile because it is already enabled by -Wall.)
New function 'lua_numbertostrbuff'2024-10-23T20:16:17+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-10-23T20:16:17+00:00urn:sha1:e3ce88c9e850b7e79751083014699c5eae1bff31
It converts a Lua number to a string in a buffer, without creating
a new Lua string.
No errors in 'luaO_pushvfstring'2024-09-20T18:56:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2024-09-20T18:56:39+00:00urn:sha1:20d42ccaaed9a84783d548d76633a5a38f0091f1
Any call to 'va_start' must have a corresponding call to 'va_end';
so, functions called between them (luaO_pushvfstring in particular)
cannot raise errors.
