Testing instructions:

*) Ensure no tests commented out below or early return in doMain

*) Compile with g++ with all warnings and run the unit test
g++ lodepng.cpp lodepng_util.cpp lodepng_unittest.cpp -Werror -Wall -Wextra -Wsign-conversion -Wshadow -pedantic -ansi -O3 && ./a.out

*) Compile with clang, which may sometimes give different warnings
clang++ lodepng.cpp lodepng_util.cpp lodepng_unittest.cpp -Werror -Wall -Wextra -Wsign-conversion -Wshadow -pedantic -ansi -O3

*) Compile with pure ISO C90 and all warnings:
mv lodepng.cpp lodepng.c ; gcc -I ./ lodepng.c examples/example_decode.c -ansi -pedantic -Werror -Wall -Wextra -O3 ; mv lodepng.c lodepng.cpp

mv lodepng.cpp lodepng.c ; clang -I ./ lodepng.c examples/example_decode.c -ansi -pedantic -Werror -Wall -Wextra -O3 ; mv lodepng.c lodepng.cpp

*) Compile with C with -pedantic but not -ansi flag so it warns about // style comments in C++-only ifdefs
mv lodepng.cpp lodepng.c ; gcc -I ./ lodepng.c examples/example_decode.c -pedantic -Werror -Wall -Wextra -O3 ; mv lodepng.c lodepng.cpp

*) test other compilers

*) try lodepng_benchmark.cpp
g++ lodepng.cpp lodepng_benchmark.cpp -Werror -Wall -Wextra -pedantic -ansi -lSDL2 -O3 && ./a.out testdata/corpus/''*

*) try the fuzzer
clang++ -fsanitize=fuzzer -DLODEPNG_MAX_ALLOC=100000000 lodepng.cpp lodepng_fuzzer.cpp -O3 -o fuzzer && ./fuzzer

clang++ -fsanitize=fuzzer,address,undefined -DLODEPNG_MAX_ALLOC=100000000 lodepng.cpp lodepng_fuzzer.cpp -O3 -o fuzzer && ./fuzzer

*) Check if all C++ examples compile without warnings:
g++ -I ./ lodepng.cpp examples/''*.cpp -Werror -W -Wall -ansi -pedantic -O3 -c

*) Check if all C examples compile without warnings:
mv lodepng.cpp lodepng.c ; gcc -I ./ lodepng.c examples/''*.c -Werror -W -Wall -ansi -pedantic -O3 -c ; mv lodepng.c lodepng.cpp

*) Check pngdetail.cpp:
g++ lodepng.cpp lodepng_util.cpp pngdetail.cpp -Werror -W -Wall -ansi -pedantic -O3 -o pngdetail
./pngdetail testdata/PngSuite/basi0g01.png

rm *.o

*) analyze with clang:
clang++ lodepng.cpp --analyze

More verbose:
clang++ --analyze -Xanalyzer -analyzer-output=text lodepng.cpp

Or html, look under lodepng.plist dir afterwards and find the numbered locations in the pages:
clang++ --analyze -Xanalyzer -analyzer-output=html lodepng.cpp

*) check for memory leaks and vulnerabilities with valgrind
(DISABLE_SLOW disables a few tests that are very slow with valgrind)
g++ -DDISABLE_SLOW lodepng.cpp lodepng_util.cpp lodepng_unittest.cpp -Wall -Wextra -pedantic -ansi -O3 -DLODEPNG_MAX_ALLOC=100000000 && valgrind --leak-check=full --track-origins=yes ./a.out

*) Try with clang++ and address sanitizer (to get line numbers, make sure 'llvm' is also installed to get 'llvm-symbolizer'
clang++ -O3 -fsanitize=address,undefined lodepng.cpp lodepng_util.cpp lodepng_unittest.cpp -Werror -Wall -Wextra -Wshadow -pedantic -ansi && ASAN_OPTIONS=allocator_may_return_null=1 ./a.out

*) remove "#include <iostream>" from lodepng.cpp if it's still in there (some are legit)
cat lodepng.cpp lodepng_util.cpp | grep iostream
cat lodepng.cpp lodepng_util.cpp | grep stdio
cat lodepng.cpp lodepng_util.cpp | grep "#include"

*) try the Makefile
make clean && make -j
rm *.o *.obj

*) check that no plain free, malloc, realloc, strlen, memcpy, memset, ... used, but the lodepng_* versions instead

*) check version dates in copyright message and LODEPNG_VERSION_STRING

*) check year in copyright message at top of all files as well as at bottom of lodepng.h

*) check examples/sdl.cpp with the png test suite images (the "x" ones are expected to show error)
g++ -I ./ lodepng.cpp examples/example_sdl.cpp -Werror -Wall -Wextra -pedantic -ansi -O3 -lSDL2 -o showpng && ./showpng testdata/PngSuite/''*.png

*) strip trailing spaces and ensure consistent newlines

*) test warnings in other compilers

*) check diff of lodepng.cpp and lodepng.h before submitting
git difftool -y
