Roberto Ierusalimschy 74b4013538 Removed macro 'changeage' 
It is simpler to use always 'setage'. The saving from 'changeage'
is too irrelevant.

Roberto Ierusalimschy b719ff9399 Removed parameter in 'collectgarbage("step")' 
A call to 'collectgarbage("step")' always performs one GC basic step.

Roberto Ierusalimschy 35a2fed2d1 Removed deprecated options in 'lua_gc' 
Options 'setpause' and 'setstepmul' were deprecated in Lua 5.4.

Roberto Ierusalimschy 842a83f09c Panic functions should not raise errors 
The standard panic function was using 'lua_tostring', which may raise
a memory-allocation error if error value is a number.

Roberto Ierusalimschy 52b899d60d Simpler coding for new representation for arrays 
With the tags comming first in a cell, we can define the whole cell
as a C type and let C do part of the address computations.

Roberto Ierusalimschy 25cd3d377e Buffer in 'luai_makeseed' measured in bytes 
In the (rare) cases when sizeof(void*) or sizeof(time_t) are not
multiples of sizeof(int), we still can use all their bytes in the seed.

Roberto Ierusalimschy 1028f296a8 Default paths stored as external strings 2023-11-13 13:41:59 -03:00
Roberto Ierusalimschy 6d042a178f Auxiliary buffer uses external strings 
The buffer system from the auxiliary library reuses its buffer
as external memory when closing long strings.

Roberto Ierusalimschy eabf425c76 Correct anchoring and GC barriers in 'loadString' 
Call to 'luaH_setint' could call the GC with the string unanchored.
Moreover, previously saved strings were being assigned to the prototype
without a barrier.

Roberto Ierusalimschy 3b57e37e48 Fixed buffers save long strings as external. 2023-11-10 12:35:48 -03:00
Roberto Ierusalimschy 024f9064f1 External strings 
Strings can use external buffers to store their contents.
 2023-11-09 17:05:42 -03:00
Roberto Ierusalimschy 7f4906f565 Towards external strings 
Long strings have a pointer to string contents.

Roberto Ierusalimschy 19afd91687 Solving merge issue with use of tables in dump/undump 
The use of tables in dump/undump to reuse strings did not exist in
the version that changed the representation of arrays, so it was not
corrected for the new API for tables.

Roberto Ierusalimschy 08a077d673 Full implementation of new representation for arrays 2023-11-03 15:26:13 -03:00
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 b8b709b6d4 Avoid direct accesses to the array part of a table 2023-10-27 16:32:49 -03:00
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.)
 2023-09-08 16:19:21 -03:00
Roberto Ierusalimschy edd8589f47 Avoid casts from unsigned long to floating-point 
Old Microsoft compilers do not support those casts.
 2023-09-08 11:34:39 -03:00
Roberto Ierusalimschy 14e416355f Added suport for Fixed Buffers 
A fixed buffer keeps a binary chunk "forever", so that the program
does not need to copy some of its parts when loading it.

Roberto Ierusalimschy f33cda8d6e New macro 'getlstr' 
Accesses content and length of a 'TString'.

Roberto Ierusalimschy 96f7714237 Field 'Proto.is_vararg' uses only one bit 
So that the other bits can be used for other purposes.

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).

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 ea39042e13 Removed redundancy in definitions of version/release 
String rendering now derived from the numeric original definitions.

Roberto Ierusalimschy f623b96932 Bug: read overflow in 'l_strcmp' 
Equality according to 'strcoll' does not imply that strings have
the same length.

Roberto Ierusalimschy 9be74ccc21 Several functions turned 'static' 
Several functions that were already being used only inside their
own file have been declared as 'static'.

Roberto Ierusalimschy 819bd51d87 Some cleaning in the new table API 2023-05-16 16:53:29 -03:00
Roberto Ierusalimschy f8d30826dd New table API for 'set' functions 2023-05-16 14:55:49 -03:00
Roberto Ierusalimschy 351ccd7332 Towards a new implementation of arrays 
The array part of a table wastes too much space, due to padding.
To avoid that, we need to store values in the array as something
different from a TValue. Therefore, the API for table access
should not assume that any value in a table lives in a *TValue.
This commit is the first step to remove that assumption: functions
luaH_get*, instead of returning a *TValue where the value lives,
receive a *TValue where to put the value being accessed.
(We still have to change the luaH_set* functions.)

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.

- Better comments about short strings in opcodes.
- luaH_newkey made static.
