| * | No more to-be-closed functions | Roberto Ierusalimschy | 2019-01-04 | 1 | -0/+1 | |
| | | | | | | | | | | | | | | | | | | | | To-be-closed variables must contain objects with '__toclose' metamethods (or nil). Functions were removed for several reasons: * Functions interact badly with sandboxes. If a sandbox raises an error to interrupt a script, a to-be-closed function still can hijack control and continue running arbitrary sandboxed code. * Functions interact badly with coroutines. If a coroutine yields and is never resumed again, its to-be-closed functions will never run. To-be-closed objects, on the other hand, will still be closed, provided they have appropriate finalizers. * If you really need a function, it is easy to create a dummy object to run that function in its '__toclose' metamethod. This comit also adds closing of variables in case of panic. | |||||
| * | Changes in the control of C-stack overflow | Roberto Ierusalimschy | 2018-12-27 | 1 | -24/+16 | |
| | | | | | | | | | | | * 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.) | |||||
| * | New functions 'lua_resetthread' and 'coroutine.kill' | Roberto Ierusalimschy | 2018-12-13 | 1 | -0/+4 | |
| | | | | | | | New functions to reset/kill a thread/coroutine, mainly (only?) to close any pending to-be-closed variable. ('lua_resetthread' also allows a thread to be reused...) | |||||
| * | Details | Roberto Ierusalimschy | 2018-12-11 | 1 | -16/+13 | |
| | | | | | | | | | - in 'luaB_tonumber', do not need to "checkany" when argument is a number. - in 'lua_resume', the call to 'luaD_rawrunprotected' cannot return a status equal to -1. | |||||
| * | Some bugs with stack reallocation by 'luaF_close' | Roberto Ierusalimschy | 2018-11-24 | 1 | -3/+6 | |
| | | | | | | | | (Long time without testing with '-DHARDSTACKTESTS'...) With the introduction of to-be-closed variables, calls to 'luaF_close' can move the stack, but some call sites where keeping pointers to the stack without correcting them. | |||||
| * | To-be-closed variables in the C API | Roberto Ierusalimschy | 2018-10-25 | 1 | -13/+19 | |

| * | Complete implementation of to-be-closed variables | Roberto Ierusalimschy | 2018-10-22 | 1 | -3/+6 | |

| * | First "complete" implementation of to-be-closed variables | Roberto Ierusalimschy | 2018-10-17 | 1 | -7/+13 | |
| | | | | | | | | Still missing: - handling of memory errors when creating upvalue (must run closing method all the same) - interaction with coroutines | |||||
| * | Towards "to closed" local variables | Roberto Ierusalimschy | 2018-10-08 | 1 | -2/+1 | |
| | | | | | | | | | | | | | Start of the implementation of "scoped variables" or "to be closed" variables, local variables whose '__close' (or themselves) are called when they go out of scope. This commit implements the syntax, the opcode, and the creation of the corresponding upvalue, but it still does not call the finalizations when the variable goes out of scope (the most important part). Currently, the syntax is 'local scoped name = exp', but that will probably change. | |||||
| * | Added "cost" for the use of C stack by a coroutine invocation. | Roberto Ierusalimschy | 2018-09-11 | 1 | -2/+8 | |
| | | | | | | | | | | Resuming a coroutine uses more C stack than other operations (such as function calls or recursive syntax). So, to avoid stack overflow in recursive coroutine invocations, either LUAI_MAXCCALLS must be too small or a coroutine invocation must "pay" a higher price. New constant LUAL_COROCSTK ("COROutine C STaK") defines how much is this price. | |||||
| * | Bug: wrong 'nCcalls' when resuming a coroutine | Roberto Ierusalimschy | 2018-07-11 | 1 | -3/+6 | |
| | | | | | | | | | The counter 'nCcalls' now includes the number of CallInfo structures pre-allocated (so that these "potential" C calls can be made without checking 'nCcalls'). So, when copying this value from a thread to another, in 'lua_resume', it must be corrected to the number of CallInfo structures in the thread being resumed. | |||||
| * | new macros 'likely'/'unlikely' with hints for jump predictions | Roberto Ierusalimschy | 2018-05-30 | 1 | -9/+9 | |

| * | in return hook, 'top' must be corrected only if smaller than 'ci->top'. | Roberto Ierusalimschy | 2018-02-17 | 1 | -2/+3 | |
| | | | | | | (It may be larger when returning multiple values, and then it must be larger to preserve that stack slice.) | |||||
