Roberto Ierusalimschy 024f9064f1 External strings
Strings can use external buffers to store their contents.
2023-11-09 17:05:42 -03:00
Roberto Ierusalimschy 9e99f3071d Merge branch 'master' into nextversion 2023-11-07 17:25:46 -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 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 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 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 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 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 02bab9fc25 Bug: Wrong line in error message for arith. errors
It also causes 'L->top' to be wrong when the error happens,
triggering an 'assert'.

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.

Roberto Ierusalimschy 0825cf237d Detail in make file for testes/libs
Everything depends on the Lua version (as given by 'lua.h')

Roberto Ierusalimschy 7d4c7ae2af Changes in opcodes for generic 'for'
Again, as the control variable is read only, the code doesn't need
to keep an internal copy of it.

Roberto Ierusalimschy 7d6a97e42b Dump doesn't need to reuse 'source'
All strings are being reused now, including 'source'.

Roberto Ierusalimschy d738c8d18b New function 'luaL_openselectedlibs'
Makes it easier to start Lua with only some standard libraries.

Roberto Ierusalimschy 8047b2d03e Tables have a 'lastfree' information only when needed
Only tables with some minimum number of entries in their hash part
have a 'lastfree' field, kept in a header before the node vector.

Roberto Ierusalimschy cfbe378f90 Small simplification in overflow check in 'getfield'
Subtracting a small non-negative int from a non-negative int cannot
overflow, and adding a non-negative int to INT_MIN cannot overflow.

Roberto Ierusalimschy 997f11f543 Bug: 'break' may not properly close variable in a 'for' loop
Function 'leaveblock' was generating "break" label before removing
variables from the closing block. If 'createlabel' created a 'close'
instruction (which it did when matching a goto/break that exited
the scope of an upvalue), that instruction would use the wrong level.

Roberto Ierusalimschy 4a00f61276 'lua_checkstack' doesn't need to check stack overflow
'luaD_growstack' already checks that. This commit also fixes an
internal bug in 'luaD_growstack': a large 'n' could cause an arithmetic
overflow when computing 'needed'.

Roberto Ierusalimschy 597a53bbc6 Bug: finalizer calling exit can corrupt finalization order
'os.exit' can call lua_close again, separating new finalizers
created after all previous finalizers were already separated.
2021-12-22 09:00:52 -03:00
Roberto Ierusalimschy 066e0f93c4 Fix debug information about finalizers
The flag CIST_FIN does not mark a finalizer, but the function that was
running when the finalizer was called. (So, the function did not call
the finalizer, but it looks that way in the stack.)
2021-12-14 12:50:05 -03:00
Roberto Ierusalimschy 0bfc572e51 Bug: GC is not reentrant
As the GC is not reentrant, finalizers should not be able to invoke it.

Roberto Ierusalimschy 48835c76c8 Wrong assert in 'collectvalidlines' 2021-11-25 10:11:05 -03:00
Roberto Ierusalimschy e8deac5a41 Avoid OP_VARARGPREP for active lines
when building the table 'activelines' for a vararg function, this
first instruction does not make the first line active.
2021-11-10 15:07:14 -03:00
Roberto Ierusalimschy bfbff3703e Bug: Wrong status in coroutine during reset
When closing variables during 'coroutine.close' or 'lua_resetthread',
the status of a coroutine must be set to LUA_OK; a coroutine should
not run with any other status. (See assertion in 'lua_callk'.)

After the reset, the status should be kept as normal, as any error
was already reported.

Roberto Ierusalimschy 74d99057a5 Bug: C stack overflow with coroutines
'coroutine.resume' did not increment counter of C calls when
continuing execution after a protected error (that is,
while running 'precover').
2021-11-03 15:04:18 -03:00
Roberto Ierusalimschy deac067ed3 Avoid overflows when incrementing parameters in C
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).
2021-09-22 13:10:39 -03:00
Roberto Ierusalimschy 9db4bfed6b Revamp of format validation in 'string.format'
When calling 'sprintf', not all conversion specifiers accept all
flags; some combinations are undefined behavior.

Roberto Ierusalimschy a393ac2554 Detail in 'testes/math.lua'

Roberto Ierusalimschy 65434b4d1b Option '-l' can give a name for the global variable.

Roberto Ierusalimschy 439e45a2f6 Bug: luaL_tolstring may get confused with negative index
When object has a '__name' metafield, 'luaL_tolstring' used the
received index after pushing a string on the stack.
