Roberto Ierusalimschy	aa8d4a782d	Details (more uniformity in error messages)	5 years ago
Roberto Ierusalimschy	efcf24be0c	'luaL_execresult' does not assume -1 status as error ISO C is silent about the return of 'system'. Windows sets 'errno' in case of errors. Linux has several different error cases, with different return values. ISO C allows 'system' to set 'errno' even if there are no errors. Here we assume that a status==0 is success (which is the case on several platforms), otherwise it is an error. If there is an error number, gives the error based on it. (The worst a spurious 'errno' can do is to generate a bad error message.) Otherwise uses the normal results.	5 years ago
Roberto Ierusalimschy	17dbaa8639	Improvements in the handling of signals Added 'volatile' to 'l_signalT' variables plus some minor changes.	5 years ago
Roberto Ierusalimschy	9514abc2da	Cleaner definition for 'TString' Use a variable-sized array to store string contents at the end of a structure 'TString', instead of raw memory.	5 years ago
Roberto Ierusalimschy	0be57b9b6d	Details in comments	5 years ago
Roberto Ierusalimschy	61a4e64a66	Back to old encoding of versions in binary files (Undoing part of commit f53eabeed8.) It is better to keep this encoding stable, so that all Lua versions can read at least the version of a binary file.	5 years ago
Roberto Ierusalimschy	9a6f47f0ed	C-Stack test does not assume minimum of 400 slots	5 years ago
Roberto Ierusalimschy	948fb628d9	Details When in test mode (#include "tests.h"), force Lua to use its own implementation of 'lua_strx2number' and 'lua_number2strx' to test them.	5 years ago
Roberto Ierusalimschy	a901c505ab	Fixed warning about casts between function pointers gcc now warns (with -Wextra) about casts between pointers to different function types. The type 'void()(void)' works as a 'void' for function pointers, cleaning the warning.	5 years ago
Roberto Ierusalimschy	0ddc0f47bd	Several details about 5.4.0 rc1 Corrected several small details: added 'const', adjusts in tabs x spaces, removed unused #includes and #defines, misspellings, etc.	5 years ago
Roberto Ierusalimschy	cac075a122	Small issue in 'exprstat' The code should not compute an instruction address before checking that it exists. (Virtually no machine complains of computing an invalid address, as long as the address is not used, but for ISO C that is undefined behavior.)	5 years ago
Roberto Ierusalimschy	9e0a8475cd	Added 'simplesect' sections to the manual 'simplesect' encloses the introductory text of sections with subsections, so that each section either is all text or is all subsections. (This commit also corrects a small brace error in the manual and extra spaces/tabs in some other files.)	5 years ago
Roberto Ierusalimschy	7ccc6d8290	Improvements in the manual Several small improvements, in particular a new subsection consolidating all status codes in the API.	5 years ago
Roberto Ierusalimschy	7288528a1e	Short strings always use all bytes in the hash Collisions in short strings occurr just by their existence, when internalizing them. (Collisions in long strings is caused/controlled by the program, when adding them as keys to the same table.)	5 years ago
Roberto Ierusalimschy	513559cc47	Fixed bug in 'string.format("%p")' The string "(null)" used for non-collectable values must be printed as a string, not as a pointer. (Bug introduced in commit `e0cbaa50fa`).	5 years ago
Roberto Ierusalimschy	e460752323	Fixed "conceptual" bug in 'luaK_setreturns' This function was computing invalid instruction addresses when the expression was not a multi-return instruction. (Virtually all machines don't raise errors when computing an invalid address, as long as the address is not accessed, but this computation is undefined behavior in ISO C.)	5 years ago
Roberto Ierusalimschy	92594f0939	Corrected direct use of 'snprintf' in 'lstrlib.c'	5 years ago
Roberto Ierusalimschy	e8a52281d9	Code style in 'ldump'/'lundump'. - function names start with lower case; - state is always the first parameter.	5 years ago
Roberto Ierusalimschy	6eb53b7526	Details Several details in code (e.g., moving a variable to the most inner scope that encloses its uses), comments, parameter names, extra tests.	5 years ago
Roberto Ierusalimschy	9b7987a9d1	OP_LOADFALSE broken in two instructions	5 years ago
Roberto Ierusalimschy	28ef7061bb	Tag values don't need to be different from type values Variants can use zero for first variant.	5 years ago
Roberto Ierusalimschy	46c3587a6f	Clearer distinction between types and tags LUA_T* represents only types; tags (types + Variants) are represented by LUA_V* constants.	5 years ago
Roberto Ierusalimschy	69c7139ff8	New macro 'makevariant' to codify variant tags	5 years ago
Roberto Ierusalimschy	5ff408d218	Changed internal representation of booleans Instead of an explicit value (field 'b'), true and false use different tag variants. This avoids reading an extra field and results in more direct code. (Most code that uses booleans needs to distinguish between true and false anyway.)	5 years ago
Roberto Ierusalimschy	e3c83835e7	Fixed bug in 'aux_rawset' In 'aux_rawset', top must be decremented after the barrier, which refers to top-1. (Bug introduced in commit c646e57fd.)	5 years ago
Roberto Ierusalimschy	bd1b87c579	Comments (mosty typos)	5 years ago
Roberto Ierusalimschy	d7bb8df841	Copyright year changed to 2020	5 years ago
Roberto Ierusalimschy	c646e57fd6	Joined common code in 'lua_rawset' and 'lua_rawsetp'	5 years ago
Roberto Ierusalimschy	e0ab13c62f	Easy way to allow Unicode characters in identifiers For those that want to try it...	5 years ago
Roberto Ierusalimschy	e0cbaa50fa	Added test for NULL in string.format("%p") ISO C states that standard library functions should not be called with NULL arguments, unless stated otherwise. 'sprintf' does not state otherwise, and it doesn't hurt to be on the safe side.	5 years ago
Roberto Ierusalimschy	3747487320	Small correction in assertion	5 years ago
Roberto Ierusalimschy	1e0ad018ce	Comment about LUA_COMPAT_LT_LE moved to proper place	5 years ago
Roberto Ierusalimschy	95735bda46	Simplifications in 'op_arith*' family of macros	5 years ago
Roberto Ierusalimschy	d30569c064	Using an enumeration for float->integer coercion modes	5 years ago
Roberto Ierusalimschy	2d92102dee	'l_mathlim' renamed to 'l_floatatt' That macro is applied to float attributes, not to limits.	5 years ago
Roberto Ierusalimschy	490ecfcaa1	Better comments about the use of 'k' in opcodes	5 years ago
Roberto Ierusalimschy	e174f43807	Manual a little more clear about string->number coersions	5 years ago
Roberto Ierusalimschy	81f2401c6d	Code reorganization for opcodes OP_FORPREP and OP_FORLOOP Parts of the code for opcodes OP_FORPREP and OP_FORLOOP were moved to functions outside the interpreter loop.	5 years ago
Roberto Ierusalimschy	508a705c1c	Removed some wrong comments Both 'tonumber' and 'tointeger' cannot change the out parameter when the conversion fails.	5 years ago
Roberto Ierusalimschy	6f1c033d72	More generic pattern when testing 'string.format' The result of 'string.format("%a", 0.0)' can have multiple zeros after the dot.	5 years ago
Roberto Ierusalimschy	5f83fb6582	Details	5 years ago
Roberto Ierusalimschy	679dc72c08	Using 'metavalues' for "metamethods" that are not methods Several "metamethods" are not required to be methods (functions), so it seems clearer not to call them metamethods. The manual now uses the word 'metavalue' for those values.	5 years ago
Roberto Ierusalimschy	1499680f9e	Comments in 'lopcodes.h' Both 'R' and 'K' are arrays, so the comments should use square brackets to index them.	5 years ago
Roberto Ierusalimschy	bdcfae2e1c	File 'bugs' no longer tracked by git The file 'bugs' reports bugs in several different versions (corresponding to different branches in the repository), without a clear division of "this bugs belongs to this version". So, it doesn't make sense to track it along with one (or many) versions.	5 years ago
Roberto Ierusalimschy	7d526e75a7	Fixed bug in tail calls of __call chains A tail call of a __call chain (a __call metamethod that itself is also not a function) was being perfomed as a regular call.	5 years ago
Roberto Ierusalimschy	c12983cf8a	Fixed warnings from Keil compiler	5 years ago
Roberto Ierusalimschy	ba9cd0d25a	Change in the prefix of messages from searchers The initial "\n\t" to properly indent a searcher message is being added by 'findloader' when building the error message, instead of being included in the original message by each searcher itself.	5 years ago
Roberto Ierusalimschy	b93f3b00bb	Added function 'luaL_buffsub'	5 years ago
Roberto Ierusalimschy	4c32d9300c	Several enhancements in the manual	5 years ago
Roberto Ierusalimschy	6e285e5392	More pious implementation of 'string.dump' In 'str__dump', the call to 'lua_dump' assumes the function is on the top of the stack, but the manual allows 'luaL_buffinit' to push stuff on the stack (although the current implementation does not). So, the call to 'luaL_buffinit' must come after the call to 'lua_dump'.	5 years ago
