Roberto Ierusalimschy 7923dbbf72 Bug: Recursion in 'getobjname' can stack overflow 
'getobjname' now broken in two, a basic version that handles locals,
upvalues, and constants, and a full version, which uses the basic
version to handle table accesses (globals and fields).

Roberto Ierusalimschy 81e4fce530 Simpler test in 'luaH_getint' 
The test whether key is inside the array part of a table uses a bit
trick to avoid computing the real size of the array part.
 2023-10-26 16:12:25 -03:00
Roberto Ierusalimschy 6baee9ef9d Removed test for "corrupted binary dump" 
Test is too non portable. (For instance, it does not work for
different number types.)

Roberto Ierusalimschy edd8589f47 Avoid casts from unsigned long to floating-point 
Old Microsoft compilers do not support those casts.

Roberto Ierusalimschy 07a9eab23a Cannot use 'getshrstr' before setting 'shrlen' 2023-08-25 15:55:14 -03:00
Roberto Ierusalimschy 9363a8b990 Documentation for "LUA_NOENV" 
Registry field "LUA_NOENV" (that signals to libraries that option -E
is on) now part of the "official" API of Lua stand-alone.

Roberto Ierusalimschy 5ab6a5756b Bug: Wrong line number for function calls 2023-08-23 13:49:27 -03:00
Roberto Ierusalimschy 9b4f39ab14 More disciplined use of 'getstr' and 'tsslen' 
We may want to add other string variants in the future; this change
documents better where the code may need to handle those variants.
 2023-08-17 15:59:28 -03:00
Roberto Ierusalimschy f4211a5ea4 More control over encoding of test files 
The few UTF-8 test files are commented as such, and there is only one
non UTF-8 test file (to test non UTF-8 sources).
 2023-08-17 10:42:56 -03:00
Roberto Ierusalimschy 1b3f507f62 Bug: Call hook may be called twice when count hook yields 
Took the opportunity and moved the code that controls call hooks
in 'luaV_execute' into a function.

Roberto Ierusalimschy 6b51133a98 Thread stacks resized in the atomic phase 
Although stack resize can be a little expensive, it seems unusual to
have too many threads needing resize during one GC cycle. On the other
hand, the change allows full collections to skip the propagate phase,
going straight from a pause to the atomic phase.

Roberto Ierusalimschy f623b96932 Bug: read overflow in 'l_strcmp' 
Equality according to 'strcoll' does not imply that strings have
the same length.
 2023-06-14 14:38:07 -03:00
Roberto Ierusalimschy 9be74ccc21 Several functions turned 'static' 
Several functions that were already being used only inside their
own file have been declared as 'static'.
 2023-05-22 14:47:54 -03:00
Roberto Ierusalimschy 09f3c2372f Option '-l' discards version sufix from file name 
Like 'require', the command-line option '-l' discards an optional
version suffix (everything after an hyphen) from a file name when
creating the module name.

Roberto Ierusalimschy 6443185167 "Emergency" new version 5.4.6 
'lua_resetthread' is back to its original signature, to avoid
incompatibilities in the ABI between releases of the same version.
New function 'lua_closethread' added with the "correct" signature.

Roberto Ierusalimschy ab859fe59b Bug: Loading a corrupted binary file can segfault 
The size of the list of upvalue names are stored separated from the
size of the list of upvalues, but they share the same array.

Roberto Ierusalimschy c4b71b7ba0 Details 
Comments in 'onelua.c'

these changes.

triggering an 'assert'.
 2023-02-08 14:15:41 -03:00
Roberto Ierusalimschy 5e08b41567 Simpler definition for LUA_STRFTIMEOPTIONS 
There is no need for those intermediate definitions.
 2023-02-07 10:48:39 -03:00
Roberto Ierusalimschy cf08915d62 New macro LUA_USE_IOS 
Do not try to detect automatically whether system is iOS; it is
simpler and more reliable to let the programmer inform that.
 2023-02-02 13:43:41 -03:00
Roberto Ierusalimschy c888ae0aea Small changes in hash of pointers 
When converting from pointer to integer, use 'uintptr_t' if available;
otherwise try 'uintmax_t', and use 'size_t' as last resource.
 2023-02-02 13:37:11 -03:00
Roberto Ierusalimschy d69789da1c Fix absence of 'system' in iOS

does not implement 'system'.
 2023-01-24 15:04:17 -03:00
Roberto Ierusalimschy 314745ed84 Avoid excessive name pollution in test files 
Test files are more polite regarding the use of globals when locals
would do, and when globals are necessary deleting them after use.
 2022-12-28 18:34:11 -03:00
Roberto Ierusalimschy 0825cf237d Detail in make file for testes/libs

Roberto Ierusalimschy 35e01ed21d Small improvements in 'lmem.c' 
Added some auxiliary macros + fixed a bug in compilation option

when it cannot run one.)
 2022-12-15 10:44:55 -03:00
Roberto Ierusalimschy 6aabf4b15e Details in some header files

before the object itself).
 2022-11-01 17:14:01 -03:00
Roberto Ierusalimschy ee645472eb Stack reallocation done with a single realloc 
To avoid the need of both the old and the new stack addresses valid
at the same time, to correct the pointers to the stack, these pointers
are changed to offsets before the reallocation and then changed back
to pointers after the reallocation.
 2022-10-31 15:06:20 -03:00
Roberto Ierusalimschy 413a393e62 Stack indices changed to union's 
That will allow to change pointers to offsets while reallocating
