Roberto Ierusalimschy	e2c07dcbf7	Improved documentation for 'lua_getinfo'	3 years ago
Roberto Ierusalimschy	8a32e0aa4a	Correction on documentation of string-buffer operations All string-buffer operations can potentially change the stack in unspecified ways; the push/pop documentation in the manual should reflect that.	3 years ago
Roberto Ierusalimschy	c0ed74c1e1	Avoid the term "undefined behavior" in the manual	3 years ago
Roberto Ierusalimschy	bef250eb8d	Details Comments and small improvements in the manual.	4 years ago
Roberto Ierusalimschy	511d53a826	lua_settop/lua_pop closes to-be-closed variables The existence of 'lua_closeslot' is no reason for lua_pop not to close to-be-closed variables too. It is too error-prone for lua_pop not to close tbc variables being popped from the stack.	4 years ago
Roberto Ierusalimschy	e7803f7dbc	New release number (5.4.3)	4 years ago
Roberto Ierusalimschy	b7eb21c1ef	Normalization of metamethod typography in the manual	4 years ago
Roberto Ierusalimschy	bc970005ce	'__close' methods can yield in the return of a C function When, inside a coroutine, a C function with to-be-closed slots return, the corresponding metamethods can yield. ('__close' metamethods called through 'lua_closeslot' still cannot yield, as there is no continuation to go when resuming.)	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	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	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	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	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	94cbe46511	Details - small corrections in the manual - ldo.c: 'docall' -> 'ccall' ('docall' already used in 'lua.c') - comments	4 years ago
Roberto Ierusalimschy	287b302acb	Revision of stackless implementation - more organized handling of 'nCcalls' - comments - deprecation of 'setcstacklimit'	4 years ago
Roberto Ierusalimschy	fbaf040f5e	Details in the manual	4 years ago
Roberto Ierusalimschy	e51564d1be	Details in comments and documentation	4 years ago
Roberto Ierusalimschy	613513d09f	Better documentation for the GC of strings in the C API Plus some other small changes.	4 years ago
Roberto Ierusalimschy	c33b1728ae	Details Added as incompatibility, in the manual, the extra return of 'io.lines'.	4 years ago
Roberto Ierusalimschy	69e84805e4	Details	4 years ago
Roberto Ierusalimschy	50523b107d	Improvements in the manual - more consistent nomenclature for error handling - more precise definition for dead objects - added algorithm used by 'math.random' - added luaL_pushfail - some other minor changes	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	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	d7bb8df841	Copyright year changed to 2020	5 years ago
Roberto Ierusalimschy	e174f43807	Manual a little more clear about string->number coersions	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	b93f3b00bb	Added function 'luaL_buffsub'	5 years ago
Roberto Ierusalimschy	4c32d9300c	Several enhancements in the manual	5 years ago
Roberto Ierusalimschy	6c0e44464b	Improvements in the manual around metamethods	5 years ago
Roberto Ierusalimschy	03cde80b58	'setCstacklimit' renamed to 'setcstacklimit' Function names in the API use only lowercase letters.	5 years ago
Roberto Ierusalimschy	be78aeae4c	Default for warnings changed to "off" Warnings are mostly a tool to help developers (e.g., by showing hidden error messages); regular users usually don't need to see them.	5 years ago
Roberto Ierusalimschy	45948e7e55	Manual corrected with the new syntax for attributes Commit `0d52913804`, with the change in the syntax of attributes, did not update the manual accordingly.	5 years ago
Roberto Ierusalimschy	b96b0b5abb	Added macro 'luaL_pushfail' The macro 'luaL_pushfail' documents all places in the standard libraries that return nil to signal some kind of failure. It is defined as 'lua_pushnil'. The manual also got a notation (@fail) to document those returns. The tests were changed to be agnostic regarding whether 'fail' is 'nil' or 'false'.	5 years ago
Roberto Ierusalimschy	ca13be9af7	Supressed errors in '__close' generate warnings	5 years ago
Roberto Ierusalimschy	a1d8eb2743	Added control messages to warnings Added the concept of control messages to the warning system, plus the implementation of the controls "@on"/"@off" to turn warnings on/off. Moreover, the warning system in the test library adds some other controls to ease the test of warnings.	5 years ago
Roberto Ierusalimschy	09b4e527a0	Detail in the manual (method 'file:setvbuf') ANSI C is vague about 'setvbuf'; most details are implementation defined. So, the manual cannot give any guaranties, either.	5 years ago
Roberto Ierusalimschy	223bb04090	Correction in the documentation of 'io.lines' The loop does not end on end of file, but when the iterator function fails to read a value. (In particular, the format "a" never fails, so a loop with 'io.lines(fname, "a")' never ends.)	5 years ago
Roberto Ierusalimschy	f645d31573	To-be-closed variables must be closed on initialization When initializing a to-be-closed variable, check whether it has a '__close' metamethod (or is a false value) and raise an error if if it hasn't. This produces more accurate error messages. (The check before closing still need to be done: in the C API, the value is not constant; and the object may lose its '__close' metamethod during the block.)	5 years ago
Roberto Ierusalimschy	2f22c6bb79	'math.randomseed' always returns the two seed components	5 years ago
Roberto Ierusalimschy	4eefef07ab	'math.randomseed()' returns the seeds it used A call to 'math.randomseed()' returns the two components of the seed it set, so that they can be used to set that same seed again.	5 years ago
Roberto Ierusalimschy	c220b0a5d0	'__close' method may be called again in case of error An error in a closing method may be caused by a lack of resources, such as memory or stack space, and the error may free enough resources (by unwinding the stack) to allow the method to work if called again. If the closing method is already running after some error (including its own), it is not called again.	5 years ago
Roberto Ierusalimschy	f6aab3ec1f	First implementation of constant propagation Local constant variables initialized with compile-time constants are optimized away from the code.	5 years ago
Roberto Ierusalimschy	4d46289331	Local attributes can be used in list of local variables The syntax for local attributes ('const'/'toclose') was unified with the regular syntax for local variables, so that we can have variables with attributes in local definitions with multiple names; for instance: local <toclose> f, <const> err = io.open(fname) This new syntax does not implement constant propagation, yet. This commit also has some small improvements to the manual.	5 years ago
Roberto Ierusalimschy	be73f72fcc	New function 'setCstacklimit' Added new functions to dynamically set the C-stack limit ('lua_setCstacklimit' in the C-API, 'debug.setCstacklimit' in Lua).	5 years ago
Roberto Ierusalimschy	d2a9b4ffb8	Detail in the manual More precision describing the variables that won't be closed if a coroutine yields forever.	5 years ago
Roberto Ierusalimschy	f39e8c06d6	Updated the documentation for the API function 'lua_gc'	6 years ago
