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 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 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.

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 14e416355f Added suport for Fixed Buffers

Roberto Ierusalimschy 1b3f507f62 Bug: Call hook may be called twice when count hook yields

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 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

creating the module name.

of randomness.
