* Avoid using large buffers in 'string.format'Roberto Ierusalimschy2019-04-121-8/+1
| | | | | | | 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.
* LUAI_MAXCCALLS renamed LUAI_MAXCSTACKRoberto Ierusalimschy2019-03-251-0/+15
| | | | | | | 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 Ierusalimschy2018-12-271-2/+2
| | | | | | | | | | * 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.)
* Visibility of non-API functions changed to "internal"Roberto Ierusalimschy2018-11-131-1/+1
| | | | | | | 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.
* Deprecated the emulation of '__le' using '__lt'Roberto Ierusalimschy2018-08-241-1/+7
| | | | | | | | | | | 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.
