Roberto Ierusalimschy	c63e5d212b	New macro 'completestate'	4 years ago
Roberto Ierusalimschy	dee6433a89	Forbid changing numerical types through compiler options 'luaconf.h' always defines options LUA_32BITS, LUA_C89_NUMBERS, LUA_INT_TYPE, and LUA_FLOAT_TYPE (using 0/1 for the first two), to avoid they being set through compiler options. (It is too easy to forget these options when compiling other software that interoperates with Lua.)	4 years ago
Roberto Ierusalimschy	2bfa13e520	Fixed some bugs around stack reallocation Long time without using HARDSTACKTESTS...	4 years ago
Roberto Ierusalimschy	e500892e18	Optimization/simplification of 'getbaseline' By producing absolute line information at regular intervals, a simple division can compute the correct entry for a given instruction.	4 years ago
Roberto Ierusalimschy	949187b049	Optimizations for line hook The function 'changedline' tries harder to avoid calling 'luaG_getfuncline' plus small changes in the use of 'L->oldpc'.	4 years ago
Roberto Ierusalimschy	58aa09a0b9	Small improvements in hooks - 'L->top' is set once in 'luaD_hook', instead of being set in 'luaD_hookcall' and 'rethook'; - resume discard arguments when returning after an yield inside a hook (arguments may interfere with the coroutine stack); - yield inside a hook asserts it has no arguments.	4 years ago
Roberto Ierusalimschy	1f81baffad	Janitorial work Comments, code details, identation.	4 years ago
Roberto Ierusalimschy	0e9254dfa0	Correct order of return hooks vs. close metamethods The return hook should be called only after closing variables (which are still part of the function). C functions were calling the hook before the metamethods.	4 years ago
Roberto Ierusalimschy	6ccd24eff5	Simpler handling of errors when creating tbc variables New field 'lua_State.ptbc' keeps to-be-closed variable until its upvalue is created, so that it can be closed in case of a memory-allocation error.	4 years ago
Roberto Ierusalimschy	d0f34d9137	Allow yields in '__close' metamethods ater errors Completes commit `b07fc10e91`. '__close' metamethods can yield even when they are being called due to an error. '__close' metamethods from C functions are still not allowed to yield.	4 years ago
Roberto Ierusalimschy	825ac8eca8	Corrected documentation for 'table.sort' The sort function must define a (strict) weak order for a correct sorting. A partial order is not enough.	4 years ago
Roberto Ierusalimschy	b07fc10e91	Allow yields inside '__close' metamethods Initial implementation to allow yields inside '__close' metamethods. This current version still does not allow a '__close' metamethod to yield when called due to an error. '__close' metamethods from C functions also are not allowed to yield.	4 years ago
Roberto Ierusalimschy	cc1692515e	New API function 'lua_closeslot' Closing a to-be-closed variable with 'lua_settop' is too restrictive, as it erases all slots above the variable. Moreover, it adds side effects to 'lua_settop', which should be a fairly basic function.	4 years ago
Roberto Ierusalimschy	ce101dcaf7	Handles '__close' errors in coroutines in "coroutine style" Errors in '__close' metamethods in coroutines are handled by the same logic that handles other errors, through 'recover'.	4 years ago
Roberto Ierusalimschy	553b37ce4f	Do not insert nil values into tables	4 years ago
Roberto Ierusalimschy	4bd10b6fe8	Better error messages for calling non-callable objects When available, use the calling code to find a suitable name for what was being called; this is particularly useful for errors of non-callable metamethods. This commit also improved the debug information for order metamethods.	4 years ago
Roberto Ierusalimschy	59e565d955	No need to recheck close method before calling it A to-be-closed variable is constant and it must have a close metamethod when it is created. A program has to go out of its way (e.g., by changing the variable's metamethod) to invalidate that check. So, it is not worth to test that again. If the program tampers with the metamethod, Lua will raise a regular error when attempting to call it.	4 years ago
Roberto Ierusalimschy	6188f3a654	Reset thread before panicking Before panicking, it is simpler to reset the thread instead of closing its variables and adjust the top manually.	4 years ago
Roberto Ierusalimschy	7af27ef59d	Cleaner handling of errors in '__close' metamethods Instead of protecting each individual metamethod call, protect the entire call to 'luaF_close'.	4 years ago
Roberto Ierusalimschy	0ceada8da9	Report last error in closing methods When there are multiple errors around closing methods, report the last error instead of the original.	4 years ago
Roberto Ierusalimschy	f9d29b0c44	Upvalues removed from 'openupval' before being closed Undo commit c220b0a5d0: '__close' is not called again in case of errors. (Upvalue is removed from the list before the call.) The common error that justified that change was C stack overflows, which are much rarer with the stackless implementation.	4 years ago
Roberto Ierusalimschy	409256b784	'coroutine.close'/'lua_resetthread' report original errors Besides errors in closing methods, 'coroutine.close' and 'lua_resetthread' also consider the original error that stopped the thread, if any.	4 years ago
Roberto Ierusalimschy	b17178b27a	Cleaner handling of floats in pack/unpack	4 years ago
Roberto Ierusalimschy	e1ceea5674	Cleaner definition for macro 'ttisclosure'	4 years ago
Roberto Ierusalimschy	748d6d4e7a	Review of asserts in 'ltests.c' The module 'ltests.c' must work correctly with asserts off, too.	4 years ago
Roberto Ierusalimschy	e2ea3b31c9	Details (do not affect regular code) * Avoids multiple definitions of 'lua_assert' in test file. * Smaller C-stack limit in test mode. * Note in the manual about the use of false * Extra test for constant reuse.	4 years ago
Roberto Ierusalimschy	23051e830a	Changes in the API of 'luaH_set' and related functions Functions to set values in a table (luaH_set, luaH_newkey, etc.) receive the new value, instead of returning a slot where to put the value.	4 years ago
Roberto Ierusalimschy	f15589f3b0	Added test cases for error messages about goto/label	4 years ago
Roberto Ierusalimschy	754ca0060f	n Windows, 'popen' accepts "[rw][bt]?" as valid modes Added the modifiers 'b' and 't' to valid modes for 'popen' in Windows.	4 years ago
Roberto Ierusalimschy	c36ced53c9	Avoid "bad programming habits" in the reference system References were using both 0 indices and nils as values in arrays. Both do not fit in the concept of a sequence, which is the kind of use that guides all Lua optimizations.	4 years ago
Roberto Ierusalimschy	d41c36bf67	'lua_assert' moved from 'lualib.h' to 'lauxlib.h' The macro is useful also in 'lauxlib.c', which does not include 'lualib.h'. Also, the definition was corrected to be "on" when LUAI_ASSERT is defined.	4 years ago
Roberto Ierusalimschy	d9d2904f09	Details Names in the parser and other details that do not change actual code.	4 years ago
Roberto Ierusalimschy	65d2294454	Changed access to global table in the registry The global table is always in the array part of the registry; we can use this fact to make its access slightly more efficient.	4 years ago
Roberto Ierusalimschy	131e3fd814	Avoid using 'signal' when 'sigaction' is available The semantics of 'signal' varies a lot among different implementations; 'sigaction' ensures a more consistent behavior.	4 years ago
Roberto Ierusalimschy	9d067ab73b	Optimization for 'n^2' Squares are much more common than other exponentiations, and 'n*n' is much more efficient than 'pow'.	4 years ago
Roberto Ierusalimschy	2f4162bc47	Compiler optimization back to '-O2' Undo commit `6a10f03ff`. Compiler performance is important, too.	4 years ago
Roberto Ierusalimschy	ab1aca94e8	Removed optimization for «if ... then goto» That optimization was too complex and caused some weird traces when debugging. The more common case «if ... then break» was kept.	4 years ago
Roberto Ierusalimschy	d282652561	Bug when growing a stack When a stack grows, its extra area can be in use, and it becomes part of the common area. So, the extra area must be kept correct all the times. (Bug introduced by commit 5aa36e894f5.)	4 years ago
Roberto Ierusalimschy	58216600eb	'luaL_newstate' should not allocate extra memory The allocation of a userdata for the state of the warn system can cause a panic if it fails; 'luaL_ref' also can fail. This commit re-implements the warn system so that it does not need an explicit state. Instead, the system uses different functions to represent the different states.	4 years ago
Roberto Ierusalimschy	94cbe46511	Details - small corrections in the manual - ldo.c: 'docall' -> 'ccall' ('docall' already used in 'lua.c') - comments	4 years ago
Roberto Ierusalimschy	69b71a6919	_PROMPT can have non-string values 'get_prompt' uses 'luaL_tolstring' to convert _PROMPT or _PROMPT2 value to a string. That conversion may invoke a '__tostring' metamethod.	4 years ago
Roberto Ierusalimschy	d742a193e5	Comments	4 years ago
Roberto Ierusalimschy	e4a38eb0e8	Fixed wrong trace of vararg functions Trace of vararg functions was skipping an instruction when returning from a call. (Bug introduced by commit 5d8ce05b3.)	4 years ago
Roberto Ierusalimschy	f07de22576	Fixed compiler option -DHARDSTACKTESTS to commit `5aa36e8`	4 years ago
Roberto Ierusalimschy	52c8679760	Fixed bug of keys removed from tables vs 'next' Fixed the bug that a key removed from a table might not be found again by 'next'. (This is needed to allow keys to be removed during a traversal.) This bug was introduced in commit `73ec04fc`.	4 years ago
Roberto Ierusalimschy	849b2ecbd2	New release number (5.4.2)	4 years ago
Roberto Ierusalimschy	30528049f1	'lua_upvalueid' returns NULL on invalid upvalue index	4 years ago
Roberto Ierusalimschy	9a89fb1c9d	Hash always use all characters in a long string Hashes for long strings are computed only when they are used as keys in a table, not a too common case. And, in that case, it is to easy to force collisions changing only the characters which are not part of the hash.	4 years ago
Roberto Ierusalimschy	c23cc86c54	Details - After converting a generic GCObject to a specific type ('gco2*'), avoid using the original GCObject (to reduce aliasing). - Small corrections in comments in 'lopcodes.h' - Added tests about who calls __close metamethods	4 years ago
Roberto Ierusalimschy	171dcd7d74	'recover' finish of 'luaD_pcall' should follow the original	4 years ago
