* Option 0 for step multiplier makes GC non-incrementalRoberto Ierusalimschy2023-12-201-2/+9
|
* Removed parameter in 'collectgarbage("step")'Roberto Ierusalimschy2023-12-011-41/+1
| | | | A call to 'collectgarbage("step")' always performs one GC basic step.
* Removed deprecated options in 'lua_gc'Roberto Ierusalimschy2023-11-301-7/+2
| | | | Options 'setpause' and 'setstepmul' were deprecated in Lua 5.4.
* Auxiliary buffer uses external stringsRoberto Ierusalimschy2023-11-132-11/+2
| | | | | The buffer system from the auxiliary library reuses its buffer as external memory when closing long strings.
* Fixed buffers save long strings as external.Roberto Ierusalimschy2023-11-101-5/+9
|
* External stringsRoberto Ierusalimschy2023-11-091-3/+23
| | | | Strings can use external buffers to store their contents.
* Merge branch 'master' into nextversionRoberto Ierusalimschy2023-11-072-14/+3

| * Bug: Recursion in 'getobjname' can stack overflowRoberto Ierusalimschy2023-11-011-0/+3
| | | | | | | | | | | | '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).
| * Removed test for "corrupted binary dump"Roberto Ierusalimschy2023-09-081-14/+0
| | | | | | | | | | Test is too non portable. (For instance, it does not work for different number types.)
* | Added suport for Fixed BuffersRoberto Ierusalimschy2023-09-051-5/+46
| | | | | | | | | | A fixed buffer keeps a binary chunk "forever", so that the program does not need to copy some of its parts when loading it.

| * Bug: Wrong line number for function callsRoberto Ierusalimschy2023-08-231-4/+4
| |
| * More control over encoding of test filesRoberto Ierusalimschy2023-08-176-28/+49
| | | | | | | | | | 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).
| * DetailsRoberto Ierusalimschy2023-07-031-1/+1

| * Option '-l' discards version sufix from file nameRoberto Ierusalimschy2023-05-151-0/+7
| | | | | | | | | | | | 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.
| * Small improvements in testsRoberto Ierusalimschy2023-05-152-21/+24
| |
| * Bug: Loading a corrupted binary file can segfaultRoberto Ierusalimschy2023-03-171-0/+14
| | | | | | | | | | 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.
| * Bug: Wrong line in error message for arith. errorsRoberto Ierusalimschy2023-02-081-0/+8
| | | | | | | | | | It also causes 'L->top' to be wrong when the error happens, triggering an 'assert'.
* | Merge branch 'master' into nextversionRoberto Ierusalimschy2022-12-2826-261/+335
|\|
| * Avoid excessive name pollution in test filesRoberto Ierusalimschy2022-12-2826-261/+335
| | | | | | | | | | Test files are more polite regarding the use of globals when locals would do, and when globals are necessary deleting them after use.

| * Detail in make file for testes/libsRoberto Ierusalimschy2022-12-231-5/+5
| | | | | | | | Everything depends on the Lua version (as given by 'lua.h')
* | Changes in opcodes for generic 'for'Roberto Ierusalimschy2022-12-221-2/+2
| | | | | | | | | | Again, as the control variable is read only, the code doesn't need to keep an internal copy of it.
* | Control variables in for loops are read onlyRoberto Ierusalimschy2022-12-213-16/+15
| |
* | Towards Lua 5.5Roberto Ierusalimschy2022-12-203-5/+5
| |
* | Dump doesn't need to reuse 'source'Roberto Ierusalimschy2022-12-201-0/+25
| | | | | | | | All strings are being reused now, including 'source'.
* | New function 'luaL_openselectedlibs'Roberto Ierusalimschy2022-12-072-7/+9
| | | | | | | | Makes it easier to start Lua with only some standard libraries.
* | Tables have a 'lastfree' information only when neededRoberto Ierusalimschy2022-11-011-2/+2
|/ | | | | Only tables with some minimum number of entries in their hash part have a 'lastfree' field, kept in a header before the node vector.
* Bug: stack overflow with nesting of coroutine.closeRoberto Ierusalimschy2022-10-251-0/+26
|
* Portability issue in a test for 'string.format'Roberto Ierusalimschy2022-10-191-2/+7
|
* Negation in constant folding of '>>' may overflowRoberto Ierusalimschy2022-09-231-0/+12
|
* Small simplification in overflow check in 'getfield'Roberto Ierusalimschy2022-09-231-0/+9
| | | | | Subtracting a small non-negative int from a non-negative int cannot overflow, and adding a non-negative int to INT_MIN cannot overflow.
* Bug: 'utf8.codes' accepts spurious continuation bytesRoberto Ierusalimschy2022-09-231-1/+11
|
* New test for table rehashRoberto Ierusalimschy2022-09-161-9/+29
|
* Bug: 'break' may not properly close variable in a 'for' loopRoberto Ierusalimschy2022-08-241-0/+20
| | | | | | | 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.
* Simpler handling of Byte Order Mark (BOM)Roberto Ierusalimschy2022-08-231-5/+30
|
* More checks and documentation for uses of EXTRA_STACKRoberto Ierusalimschy2022-05-261-0/+10
|
* Bug: 'lua_settop' may use an invalid pointer to stackRoberto Ierusalimschy2022-05-251-0/+22
|
* 'lua_checkstack' doesn't need to check stack overflowRoberto Ierusalimschy2022-05-231-9/+6
| | | | | | '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'.
* Bug: Wrong code generation in bitwise operationsRoberto Ierusalimschy2022-04-251-0/+25
|
* Bug: Lua can generate wrong code when _ENV is <const>Roberto Ierusalimschy2022-02-151-0/+10
|
* Bug: finalizer calling exit can corrupt finalization orderRoberto Ierusalimschy2021-12-221-0/+28
| | | | | 'os.exit' can call lua_close again, separating new finalizers created after all previous finalizers were already separated.
* Fix debug information about finalizersRoberto Ierusalimschy2021-12-142-2/+2
| | | | | | 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.)
* Bug: GC is not reentrantRoberto Ierusalimschy2021-12-132-5/+6
| | | | As the GC is not reentrant, finalizers should not be able to invoke it.
* Wrong assert in 'collectvalidlines'Roberto Ierusalimschy2021-11-251-1/+1
|
* Avoid OP_VARARGPREP for active linesRoberto Ierusalimschy2021-11-101-0/+43
| | | | | when building the table 'activelines' for a vararg function, this first instruction does not make the first line active.
* Bug: Wrong status in coroutine during resetRoberto Ierusalimschy2021-11-081-1/+43
| | | | | | | | | 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.
* Bug: C stack overflow with coroutinesRoberto Ierusalimschy2021-11-031-0/+14
| | | | | | 'coroutine.resume' did not increment counter of C calls when continuing execution after a protected error (that is, while running 'precover').
* Avoid overflows when incrementing parameters in CRoberto Ierusalimschy2021-09-222-0/+23
| | | | | | 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).
