Author	SHA1	Message	Date
Roberto Ierusalimschy	7ceb2154ed	Fixed small bugs/issues - In 'readutf8esc' (llex.c), the overflow check must be done before shifting the accumulator. It was working because tests were using 64-bit longs. Failed with 32-bit longs. - In OP_FORPREP (lvm.c), avoid negating an unsigned value. Visual Studio gives a warning for that operation, despite being well defined in ISO C. - In 'luaV_execute' (lvm.c), 'cond' can be defined only when needed, like all other variables.	6 years ago
Roberto Ierusalimschy	1e0c73d5b6	Changes in the validation of UTF-8 All UTF-8 encoding functionality (including the escape sequence '\u') accepts all values from the original UTF-8 specification (with sequences of up to six bytes). By default, the decoding functions in the UTF-8 library do not accept invalid Unicode code points, such as surrogates. A new parameter 'nonstrict' makes them accept all code points up to (2^31)-1, as in the original UTF-8 specification.	6 years ago
Roberto Ierusalimschy	57f5b81da9	Bug: Long brackets with a huge number of '=' causes overflow A long bracket with too many equal signs can overflow the 'int' used for the counting and some arithmetic done on the value. Changing the counter to 'size_t' avoids that. (Because what is counted goes to a buffer, an overflow in the counter will first raise a buffer-overflow error.)	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
