As the GC is not reentrant, finalizers should not be able to invoke it.
Avoid overflows when incrementing parameters in C2021-09-22T16:10:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-09-22T16:10:39+00:00urn:sha1:deac067ed39a44c001599c0d15de09872496b2aa
Any C function can receive maxinteger as an integer argument, and
therefore cannot increment it without some care (e.g., doing unsigned
arithmetic as the core does).

More uses of macros 'likely'/'unlikely' (renamed to
'l_likely'/'l_unlikely'), both in range (extended to the
libraries) and in scope (extended to hooks, stack growth).

Added macro 'luaL_pushfail'2019-08-16T17:58:02+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2019-08-16T17:58:02+00:00urn:sha1:b96b0b5abbf40cbdbed7952bf35a5a27ddf75928
The macro 'luaL_pushfail' documents all places in the standard libraries
that return nil to signal some kind of failure. It is defined as
'lua_pushnil'. The manual also got a notation (@fail) to document those
returns. The tests were changed to be agnostic regarding whether 'fail'
is 'nil' or 'false'.
Added control messages to warnings2019-08-15T16:44:36+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2019-08-15T16:44:36+00:00urn:sha1:a1d8eb27431c02c4529be1efd92143ad65434f3a
Added the concept of control messages to the warning system, plus the
implementation of the controls "@on"/"@off" to turn warnings on/off.
Moreover, the warning system in the test library adds some other
controls to ease the test of warnings.
Function 'warn' is vararg2019-06-04T14:22:21+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2019-06-04T14:22:21+00:00urn:sha1:14edd364c3abcb758e74c68a2bdd4ddaeefdae2a
Instead of a 'tocont' flag, the function 'warn' in Lua now receives all
message pieces as multiple arguments in a single call. Besides being
simpler to use, this implementation ensures that Lua code cannot create
unfinished warnings.
'print' does not call 'tostring' to format its arguments2019-04-10T15:58:14+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2019-04-10T15:58:14+00:00urn:sha1:8ba4523cccf59093543cec988b07957193d55692Changes in the warning system2019-03-14T18:30:54+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2019-03-14T18:30:54+00:00urn:sha1:b56d4e570a60a8e84df8288c3122eb5bb5c20af6
- The warning functions get an extra parameter that tells whether
message is to be continued (instead of using end-of-lines as a signal).
- The user data for the warning function is a regular value, instead
of a writable slot inside the Lua state.
