| * | Removed internal cache for closures | Roberto Ierusalimschy | 2018-11-01 | 1 | -1/+1 | |
| | | | | | | | | | | | | | | | | | | | | The mechanism of "caching the last closure created for a prototype to try to reuse it the next time a closure for that prototype is created" was removed. There are several reasons: - It is hard to find a natural example where this cache has a measurable impact on performance. - Programmers already perceive closure creation as something slow, so they tend to avoid it inside hot paths. (Any case where the cache could reuse a closure can be rewritten predefining the closure in some variable and using that variable.) - The implementation was somewhat complex, due to a bad interaction with the generational collector. (Typically, new closures are new, while prototypes are old. So, the cache breaks the invariant that old objects should not point to new ones.) | |||||
| * | First "complete" implementation of to-be-closed variables | Roberto Ierusalimschy | 2018-10-17 | 1 | -2/+2 | |
| | | | | | | | | Still missing: - handling of memory errors when creating upvalue (must run closing method all the same) - interaction with coroutines | |||||
| * | Removed extra information from RCS keyword strings | Roberto Ierusalimschy | 2018-08-23 | 1 | -1/+1 | |
| | | | | | | Version numbers and dates (mostly wrong) from RCS keyword strings removed from all source files; only the file name are kept. | |||||
| * | no need to check whether libraries and host use the same kernel; | Roberto Ierusalimschy | 2018-06-18 | 1 | -6/+5 | |
| | | | | | Lua should work correctly with several copies of the kernel | |||||

| | | | | | addresses of static variables | |||||
| * | no more 'luaO_nilobject' to avoid comparison of global variable addresses | Roberto Ierusalimschy | 2018-06-01 | 1 | -3/+2 | |

| * | no more 'stackless' implementation; 'luaV_execute' calls itself | Roberto Ierusalimschy | 2017-11-23 | 1 | -2/+26 | |
| | | | | | | recursively to execute function calls. 'unroll' continues all executions suspended by an yield (through a long jump) | |||||

| * | revamping the incremental collector | Roberto Ierusalimschy | 2017-05-26 | 1 | -10/+2 | |
