2021-08-03lua fix potential null warningWilliam Wilgus1-2/+4
I'm not sure this would happen but I suspect its possible to get malformed data back from lineinfo as this is how the error system tracks code flow and this is a hacked add-on to allow RLE (run length encoding) of said code flow data Change-Id: I4b914c632935f8b1a9fa960212c58e810b2db738
2019-08-08lua LCD (Lua Compact Debug) patchWilliam Wilgus1-0/+103
LCD developed 9/2015 by Terry Ellison We've already discarded the ldebug module from lua it only makes sense to discard the debug info as well adds 1.5 K to the binary saves 8 Kb on the base state once scripts start getting called i've seen 10-50Kb savings but it all depends on what exactly you are running Change-Id: Ibb74f344df1c4c96380ec6c98b010a810e9ae9cc

2018-06-05Fix lua failure to catch divide by zero and NaN exceptionsWilliam Wilgus1-5/+8
I can only assume in the course of the original conversion to fixed point math in RbLua the fact that division by zero and NaN handling was to be caught as a graceful exception by the floating point handler was overlooked. As a result lua doesn't handle these exceptions and instead results in a panic on the device. This patch fixes this handling in the lexer for compile time Inf and Nan results and in the luavm for runtime division by zero (Inf) I missed the runtime exception of n%0 added checks for that as well..

2014-04-02Revert "Update lua plugin to 5.2.3"Marcin Bukat1-221/+179
FILE typedef to *void needs more work to not break sim and application builds. I checked only a few random native builds unfortunately. Sorry for inconvenience.
2014-04-02Update lua plugin to 5.2.3Richard Quirk1-179/+221
Prior to this patch the Lua plugin used version 5.1.4. This change reduces the number of modifications in the Lua source using some new defines and because the upstream source is now more flexible. Unless otherwise stated, l*.[ch] files are taken unmodified from the upstream lua-5.2.3. fscanf.c: file descriptors in rockbox are just ints, they are hidden behind a void* now so liolib requires less modifications. fscanf is updated to use void* too. getc.c: this is a new file required for getc implementation in lauxlib.c lauxlib.c: LoadF replaced FILE* with int, the rockbox file descriptor int are cast to FILE* (actually void* due to typedef). getc uses the PREFIX version. stdin is not used, as per 5.1.4. lbaselib.c: now uses strspn in the number parsing. print uses DEBUGF now rather than being commented out. lbitlib.c: use the built-in version from 5.2.3 rather than Reuben Thomas's external library. Backwards compatible and adds some new bit operations. ldo.c: the LUAI_THROW/TRY defines are now in the core lua code, so have been removed from rockconf.h liolib.c: here the implementation has changed to use the LStream from the original source, and cast the FILE* pointers to int. This has reduced the number of modifications from the upstream version. llex.c: the only change from upstream is to remove the locale include. lmathlib.c: updated from the 5.2.3 version and re-applied the changes that were made vs 5.1.4 for random numbers and to remove unsupported float functions. loadlib.c: upstream version, with the 5.1.4 changes for missing functions. lobject.c: upstream version, with ctype.h added and sprintf changed to snprintf. loslib.c: upstream version with locale.h removed and 5.1.4 changes for unsupportable functions. lstrlib.c: sprintf changed to snprintf. ltable.c: upstream with the hashnum function from 5.1.4 to avoid frexp in luai_hashnum. luaconf.h: updated to 5.2.3 version, restored relevant parts from the original 5.1.4 configuration. The COMPAT defines that are no longer available are not included. lundump.c: VERSION macro conflicts with the core Rockbox equivalent. rocklib.c: luaL_reg is no longer available, replaced by luaL_Reg equivalent. Moved checkboolean/optboolean functions to this file and out of core lua files. luaL_getn is no longer available, replaced by luaL_rawlen. luaL_register is deprecated, use the newlib/setfuncs replacements. rli_init has to be called before setting up the newlib to avoid overwriting the rb table. rocklib_aux.pl: use rli_checkboolean from rocklib.c. rocklua.c: new default bits library used, update the library loading code with idiomatic 5.2 code. strcspn.c: no longer needed, but strspn.c is required for strspn in lbaselib.c Change-Id: I0c7945c755f79083afe98ec117e1e8cf13de2651 Reviewed-on: http://gerrit.rockbox.org/774 Tested: Richard Quirk <richard.quirk@gmail.com> Reviewed-by: Marcin Bukat <marcin.bukat@gmail.com>
