Set errno to zero before calling any function where we may use its
errno, and check errno for zero before using it (as functions may
not set it even in error).
Simpler definition for LUA_STRFTIMEOPTIONS2023-02-07T13:48:39+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-02-07T13:48:39+00:00urn:sha1:5e08b41567c5723c9f599d02a7511aa398f7c646
There is no need for those intermediate definitions.
New macro LUA_USE_IOS2023-02-02T16:43:41+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-02-02T16:43:41+00:00urn:sha1:cf08915d62e338c987b71c078b148490510e9fe7
Do not try to detect automatically whether system is iOS; it is
simpler and more reliable to let the programmer inform that.
Fix absence of 'system' in iOS2023-01-24T18:04:17+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2023-01-24T18:04:17+00:00urn:sha1:d69789da1ccfa4db7c241de6b471d6b729f1561e
Despite claiming to be ISO, the C library in some Apple platforms
does not implement 'system'.
Small simplification in overflow check in 'getfield'2022-09-23T13:57:35+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2022-09-23T13:57:35+00:00urn:sha1:cfbe378f906061ee56f91acfbdf569d0d3fb9556
Subtracting a small non-negative int from a non-negative int cannot
overflow, and adding a non-negative int to INT_MIN cannot overflow.
Broadening the use of branch hints2021-02-24T14:14:44+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2021-02-24T14:14:44+00:00urn:sha1:59c88f846d1dcd901a4420651aedf27816618923
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).
'luaL_execresult' does not assume -1 status as error2020-05-22T18:39:29+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-05-22T18:39:29+00:00urn:sha1:efcf24be0c22cba57b298161bf4ab0561fd3c08e
ISO C is silent about the return of 'system'. Windows sets 'errno' in
case of errors. Linux has several different error cases, with different
return values. ISO C allows 'system' to set 'errno' even if there are no
errors. Here we assume that a status==0 is success (which is the case
on several platforms), otherwise it is an error. If there is an error
number, gives the error based on it. (The worst a spurious 'errno'
can do is to generate a bad error message.) Otherwise uses the normal
results.
Several details about 5.4.0 rc12020-04-23T17:48:15+00:00Roberto Ierusalimschyroberto@inf.puc-rio.br2020-04-23T17:48:15+00:00urn:sha1:0ddc0f47bd2a03678e1afbc384550aecb55a318f
Corrected several small details: added 'const', adjusts in tabs x
spaces, removed unused #includes and #defines, misspellings, etc.

- Range in date table extended to full 32 bits.
- Easier support for times represented as floats.
- Added more tests.
