* Clearer handling of gray lists when entering generational modeRoberto Ierusalimschy2020-08-031-0/+1
| | | | | | | | When entering generational mode, all objects are old. So, the only objects that need to be in a gray list are threads, which can be assigned without barriers. Changes in anything else (e.g., weak tables) will trigger barriers that, if needed, will add the object to a gray list.
* Function 'printobj' in 'ltests.c' made publicRoberto Ierusalimschy2020-07-271-1/+7
| | | | It helps to have this function available for debugging.
* Macro LUAI_ASSERT eases turning assertions onRoberto Ierusalimschy2020-07-081-3/+1
|
* DetailsRoberto Ierusalimschy2020-04-301-5/+9
| | | | | When in test mode (#include "tests.h"), force Lua to use its own implementation of 'lua_strx2number' and 'lua_number2strx' to test them.
* DetailsRoberto Ierusalimschy2020-02-271-3/+0
| | | | | Several details in code (e.g., moving a variable to the most inner scope that encloses its uses), comments, parameter names, extra tests.
* Clearer distinction between types and tagsRoberto Ierusalimschy2020-01-311-1/+1
| | | | | LUA_T* represents only types; tags (types + Variants) are represented by LUA_V* constants.
* Small changes around C-stack limitRoberto Ierusalimschy2019-06-261-1/+1
| | | | | | | | | - 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'.
* New function 'setCstacklimit'Roberto Ierusalimschy2019-06-181-1/+1
| | | | | Added new functions to dynamically set the C-stack limit ('lua_setCstacklimit' in the C-API, 'debug.setCstacklimit' in Lua).
* LUAI_MAXCCALLS renamed LUAI_MAXCSTACKRoberto Ierusalimschy2019-03-251-2/+2
| | | | | | | 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.
* Changes in the control of C-stack overflowRoberto Ierusalimschy2018-12-271-1/+1
| | | | | | | | | | * 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.)
* Added opcodes for arithmetic with K operandsRoberto Ierusalimschy2018-11-231-1/+0
| | | | | | | | Added opcodes for all seven arithmetic operators with K operands (that is, operands that are numbers in the array of constants of the function). They cover the cases of constant float operands (e.g., 'x + .0.0', 'x^0.5') and large integer operands (e.g., 'x % 10000').
* Deprecated the emulation of '__le' using '__lt'Roberto Ierusalimschy2018-08-241-0/+1
| | | | | | | | | | | 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).
* Removed extra information from RCS keyword stringsRoberto Ierusalimschy2018-08-231-1/+1
| | | | | Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept.
