* Deprecated the emulation of '__le' using '__lt'Roberto Ierusalimschy2018-08-241-12/+9
| | | | | | | | | | | 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).
* Added "emergency collection" to 'io.tmpfile' and 'os.tmpname'Roberto Ierusalimschy2018-07-271-0/+14
| | | | | | | | These operations also can give errors for lack of resources, so they also will try "emergency collections" in case of resource errors. Because there are now two libraries with that kind of handling, 'resourcetryagain' was moved to the auxiliary library to be shared by the libraries.
