Guru Mediaton Error if readonly cache enabled and table element doesn't exists #43

Closed jolivepetrus closed 7 years ago

jolivepetrus commented 7 years ago

If "Use cache for readonly tables access (experimental)" is enabled in Kconfig, if a table's key doesn't exists a Guru Mediaton Error is raided. Examles:

Seeing the PC here reminds me of two scripts I created recently. On my PC I have put both into ../xtensa-esp32-elf/bin/

backtrace.sh

!/bin/bash

if [ -z $1 ] ; then echo -n "backtrace: " read backtrace else backtrace=$* fi

BASE=$(dirname $0) for address in $backtrace; do $BASE/getline.sh $address; done

getline.sh

!/bin/bash

if [ -z $1 ] ; then echo -n "address: " read address else address=$1 fi

xtensa-esp32-elf-addr2line -aipsfC -e ./build/lua_rtos.elf $address

So I just need to call

~/esp32/Lua-RTOS-ESP32$ backtrace.sh 0x40001d53:0x3ffcbad0 0x401152c8:0x3ffcbaf0 0x40132702:0x3ffcbb10 0x4010479d:0x3ffcbb30 0x40115673:0x3ffcbb50 0x4011580d:0x3ffcbb70 0x40115834:0x3ffcbb90 0x40115c8c:0x3ffcbbb0 0x401152d6:0x3ffcbbd0 0x4011598d:0x3ffcbc50 0x40116925:0x3ffcbc80 0x400fbd7e:0x3ffcbcb0 0x4010fdb4:0x3ffcbe70 0x4010ff06:0x3ffcbff0 0x40110125:0x3ffcc010 0x40110199:0x3ffcc030 0x40115673:0x3ffcc050 0x4011580d:0x3ffcc070 0x40115834:0x3ffcc090 0x40115c8c:0x3ffcc0b0 0x401152d6:0x3ffcc0d0 0x4011598d:0x3ffcc150 0x40116925:0x3ffcc180 0x401101d3:0x3ffcc1b0 0x401447b6:0x3ffcc1d0 0x400fb79d:0x3ffcc1f0

Where all the numbers are just copy/paste out of the gtkterm window.

Try with https://github.com/whitecatboard/Lua-RTOS-ESP32/commit/204a01fed97ef8afc522c56b9e1cda56edc0da8a.

That fixes it, and works with CONFIG_LUA_RTOS_LUA_USE_ROTABLE_CACHE both set and unset.
