This adds a minifier fuzzer. There is also an utf-8 fuzzer, but it is disabled until #1187 is fixed.
Run all fuzzers bug the utf-8 one in the github CI fuzz.
This adds a fuzzer for at_pointer() which recently had a bug.
The #1142 bug had been found with this fuzzer
Also, it polishes the github action job:
cross pollinate the fuzzer corpora (lets fuzzers reuse results from other fuzzers)
use github action syntax instead of bash checks
only run on push if on master
This adds a fuzzer which parses the same input using all the available implementations (haswell, westmere, fallback on x64).
This should get the otherwise uncovered sourcefiles (mostly fallback) to show up in the fuzz coverage.
For instance, the fallback directory has only one line covered.
As of the 20200909 report, 1866 lines are covered out of 4478.
Also, it will detect if the implementations behave differently:
by making sure they all succeed, or all error
turning the parsed data into text again, should produce equal results
While at it, I corrected some minor things:
clean up building too many variants, run with forced implementation (closes#815 )
always store crashes as artefacts, good in case the fuzzer finds something
return value of the fuzzer function should always be 0
reduce log spam
introduce max size for the seed corpus and the CI fuzzer
This enables the minify fuzzer, which has been disabled because it did not pass the oss-fuzz instrumentation test. Now it does, after changes in simdjson (https://github.com/lemire/simdjson/issues/186).
* get minify running (api change)
* disable benchmarks when compiling fuzzers
* catch exceptions from the minify fuzzer
* enable repeated corpus creation without recursive inclusion of zip
* remove leftover comment
* add basic fuzzing using libFuzzer
* let cmake respect cflags, otherwise the fuzzer flags go unnoticed
also, integrates badly with oss-fuzz
* add new fuzzer for minification, simplify the old one
* add fuzzer for the dump example
* clang format
