Roberto Ierusalimschy	69b77b6fde	Changed the growth rate of string buffers The growth rate of string buffers was reduced from 2 to 1.5 (3/2). As string buffers start larger (256~1024 bytes), they don't need to grow that fast. Moreover, a lower rate allows multiplicative growth up to larger sizes (3/2 of the maximum). (After that, the growth becomes linear, which is mostly useless.)	2 years ago
Roberto Ierusalimschy	4a00f61276	'lua_checkstack' doesn't need to check stack overflow 'luaD_growstack' already checks that. This commit also fixes an internal bug in 'luaD_growstack': a large 'n' could cause an arithmetic overflow when computing 'needed'.	2 years ago
Roberto Ierusalimschy	1e6918d553	Details - Removed unused (and trivial) definition LUA_UNSIGNEDBITS - Alignment structure in pack/unpack moved to a narrower scope	4 years ago
Roberto Ierusalimschy	eadd8c7178	Added option LUA_NOBUILTIN This option allows external code to avoid the use of gcc builtin macro '__builtin_expect' in the Lua API.	4 years ago
Roberto Ierusalimschy	a7b8b27dd3	Uses of "likely" in macros active to all users The use of 'l_likely' in auxlib macros 'luaL_argcheck' and 'luaL_argexpected' should not be restricted to Lua's own code. For that, 'l_likely' was renamed to 'luai_likely' to be exported to external code.	4 years ago
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	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	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	2d92102dee	'l_mathlim' renamed to 'l_floatatt' That macro is applied to float attributes, not to limits.	5 years ago
Roberto Ierusalimschy	e888976bc6	Details (typos in comments)	5 years ago
Roberto Ierusalimschy	8b7cfee26b	Small changes around C-stack limit - Better documentation in 'testes/cstack.lua' about using 'debug.setCstacklimit' to find a good limit. - Constant LUAI_MAXCSTACK gets added CSTACKERR (extra stack for error handling), so that it is compatible with the argument to 'debug.setCstacklimit'.	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	347d6961ac	Define LUA_MAXUNSIGNED as a preprocessor constant The previous definition of LUA_MAXUNSIGNED used a typecast, making it unsuitable for constant expressions in the preprocessor.	6 years ago
Roberto Ierusalimschy	279c3a6961	A few changes in tests about number of bits in integers - The preprocessor must work with at least 'long', and therefore must do shifts of up to 31 bits correctly. - Whenever possible, use unsigned types in shifts.	6 years ago
Roberto Ierusalimschy	49c42f3615	Some improvements in 'luaconf.h' Added '#if !defined' in some definitions to allow external definitions; more comments; other small changes.	6 years ago
Roberto Ierusalimschy	7c5786479c	A few more improvements in 'luaO_pushvfstring' - 'L' added to the 'BuffFS' structure - '%c' does not handle control characters (it is not its business. This now is done by the lexer, who is the one in charge of that kind of errors.) - avoid the direct use of 'l_sprintf' in the Lua kernel	6 years ago
Roberto Ierusalimschy	3da34a5fa7	Revamp of 'lua_pushfstring' / 'luaO_pushvfstring' The function 'luaO_pushvfstring' now uses an internal buffer to concatenate small strings, instead of pushing all pieces on the stack. This avoids the creation of several small Lua strings for each piece of the result. (For instance, a format like "n: '%d'" used to create three intermediate strings: "n: '", the numeral, and "'". Now it creates none.)	6 years ago
Roberto Ierusalimschy	2d3f095448	Avoid using large buffers in 'string.format' The result of "string.format("%.99f", -1e308) is 410 characters long, but all other formats have much smaller limits (at most 99 plus a fex extras). This commit avoids 'string.format' asking for a buffer ~400 chars large when ~100 will do.	6 years ago
Roberto Ierusalimschy	0443ad9e28	LUAI_MAXCCALLS renamed LUAI_MAXCSTACK The limit LUAI_MAXCCALLS was renamed LUAI_MAXCSTACK, which better represents its meaning. Moreover, its definition was moved to 'luaconf.h', given its importance now that Lua does not use a "stackless" implementation.	6 years ago
Roberto Ierusalimschy	ba7da13ec5	Changes in the control of C-stack overflow * unification of the 'nny' and 'nCcalls' counters; * external C functions ('lua_CFunction') count more "slots" in the C stack (to allow for their possible use of buffers) * added a new test script specific for C-stack overflows. (Most of those tests were already present, but concentrating them in a single script easies the task of checking whether 'LUAI_MAXCCALLS' is adequate in a system.)	6 years ago
Roberto Ierusalimschy	d40cd315f5	Visibility of non-API functions changed to "internal" The visibility for functions marked as LUAI_FUNC was changed from "hidden" to "internal". These functions cannot be called from outside the Lua kernel, and "internal" visibility offers more chances for optimizations.	6 years ago
Roberto Ierusalimschy	8c8a91f2ef	Deprecated the emulation of '__le' using '__lt' As hinted in the manual for Lua 5.3, the emulation of the metamethod for '__le' using '__le' has been deprecated. It is slow, complicates the logic, and it is easy to avoid this emulation by defining a proper '__le' function. Moreover, often this emulation was used wrongly, with a programmer assuming that an order is total when it is not (e.g., NaN in floating-point numbers).	6 years ago
Roberto Ierusalimschy	f99509581e	Removed extra information from RCS keyword strings Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.	6 years ago
Roberto Ierusalimschy	f59e6a93c0	opening functions must be exported!	6 years ago
Roberto Ierusalimschy	b43300c14f	change in 'LUAI_DDEC' to allow variables to be static in 'onelua' + change in 'LUAMOD_API' as opening functions do not need to be global	6 years ago

Roberto Ierusalimschy	de3fd8ab83	Handling of LUA_PATH/LUA_CPATH moved from package library to stand alone interpreter (so that 'lua.c' concentrates all handling of environment variables)	8 years ago

Roberto Ierusalimschy	48098c42ff	generic definitions for float types moved to before variable definitions (so that specific cases can redefine these generic definitions if needed)	9 years ago
