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
Roberto Ierusalimschy	5aa36e894f	No more field 'lua_State.stacksize' The stack size is derived from 'stack_last', when needed. Moreover, the handling of stack sizes is more consistent, always excluding the extra space except when allocating/deallocating the array.	4 years ago
Roberto Ierusalimschy	9ecd446141	Avoid shrinking stacks to often Shrink a stack only when the final stack size can be at most 2/3 the previous size with half of its entries empty. This commit also improves the clarity of 'luaD_growstack'.	4 years ago
Roberto Ierusalimschy	fb172d0a92	No need for 'volatile' in string.pack/unpack Type punning an address to 'char *' should be always safe.	4 years ago
Roberto Ierusalimschy	0085db4596	Avoid GCs when testing stack overflow A GC step may invoke some finalizer, which may error and emit a warning due to stack overflfow.	4 years ago
Roberto Ierusalimschy	490d42b5f8	Correct handling of 'luaV_execute' invocations The previous stackless implementations marked all 'luaV_execute' invocations as fresh. However, re-entering 'luaV_execute' when resuming a coroutine should not be a fresh invocation. (It works because 'unroll' called 'luaV_execute' for each call entry, but it was slower than letting 'luaV_execute' finish all non-fresh invocations.)	4 years ago
Roberto Ierusalimschy	287b302acb	Revision of stackless implementation - more organized handling of 'nCcalls' - comments - deprecation of 'setcstacklimit'	4 years ago
Roberto Ierusalimschy	5d8ce05b3f	Back to a stackless implementation A "with stack" implementation gains too little in performance to be worth all the noise from C-stack overflows. This commit is almost a sketch, to test performance. There are several pending stuff: - review control of C-stack overflow and error messages; - what to do with setcstacklimit; - review comments; - review unroll of Lua calls.	4 years ago

Roberto Ierusalimschy	8496112a18	Better documentation for 'lctype.h' The old documentation said that 'ltolower' only works for alphabetic characters. However, 'l_str2d' uses it (correctly) also on dots ('.').	4 years ago
