Roberto Ierusalimschy	59c88f846d	Broadening the use of branch hints More uses of macros 'likely'/'unlikely' (renamed to 'l_likely'/'l_unlikely'), both in range (extended to the libraries) and in scope (extended to hooks, stack growth).	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	1ecfbfa1a1	Fixed bug: invalid mode can crash 'io.popen'	4 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	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	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	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	e888976bc6	Details (typos in comments)	5 years ago
Roberto Ierusalimschy	924bed7297	Methods separated from metamethods in 'io' In the 'io' library, changed the use of the metatable also as its own "method table", so that metamethods cannot be accessed as if they were methods. (For instance, 'io.stdin.__gc' does not result in the finalizer metamethod anymore.)	5 years ago
Roberto Ierusalimschy	b293ae0577	Details - new error message for "attempt to assign to const variable" - note in the manual about compatibility options - comments - small changes in 'read_line' and 'pushstr'	6 years ago
Roberto Ierusalimschy	0b63d79b36	Details - 'luaL_setfuncs' avoids creating closures for placeholders. - Fixed some warnings about unused values in comma expressions. - Comments.	6 years ago
Roberto Ierusalimschy	7f6f70853c	To-be-closed variable in 'for' loop separated from the state The variable to be closed in a generic 'for' loop now is the 4th value produced in the loop initialization, instead of being the loop state (the 2nd value produced). That allows a loop to use a state with a '__toclose' metamethod but do not close it. (As an example, 'f:lines()' might use the file 'f' as a state for the loop, but it should not close the file when the loop ends.)	6 years ago
Roberto Ierusalimschy	2fc6b55dae	Removed resource-related "emergency collections" New to-be-closed variables is a better way to ensure the proper release of resources.	6 years ago
Roberto Ierusalimschy	947a372f58	State in generic 'for' acts as a to-be-closed variable The implicit variable 'state' in a generic 'for' is marked as a to-be-closed variable, so that the state will be closed as soon as the loop ends, no matter how. Taking advantage of this new facility, the call 'io.lines(filename)' now returns the open file as a second result. Therefore, an iteraction like 'for l in io.lines(name)...' will close the file even when the loop ends with a break or an error.	6 years ago
Roberto Ierusalimschy	0a9aca56ca	Added a '__close' metamethod to file handles	6 years ago
Roberto Ierusalimschy	3d838f635c	Added "emergency collection" to 'io.tmpfile' and 'os.tmpname' These operations also can give errors for lack of resources, so they also will try "emergency collections" in case of resource errors. Because there are now two libraries with that kind of handling, 'resourcetryagain' was moved to the auxiliary library to be shared by the libraries.	6 years ago
Roberto Ierusalimschy	e885dee5ab	File operations try an "emergency collection" when failing If a file operation fails do to lack of resources (too many open files or not enough memory), it does a full garbage collection and tries the operation again. Lack of resources are "too many open files" (process wise and system wise) and "not enough memory". The code is full of '#if's because error codes are not part of the standard ISO C.	6 years ago
