Remove the `fuzzing_engines` attribute from `project.yaml`s if redundant (i.e., all default engines are included in that YAML file). 3. Temporarily disable `centipede` on `c`/`c++` projects that previously use all `DEFAULT_ENGINES` (200 projects did not specify `fuzzing_engines` in `project.yaml`) so that we can gradually enable centipede later them later.	2023-04-21 09:48:45 +10:00

Make `Centipede` a default fuzzing engine (#10109 )

1. Add `centipede` to `DEFAULT_ENGINES`.
2. Remove the `fuzzing_engines` attribute from `project.yaml`s if
redundant (i.e., all default engines are included in that YAML file).
3. Temporarily disable `centipede` on `c`/`c++` projects that previously
use all `DEFAULT_ENGINES` (200 projects did not specify
`fuzzing_engines` in `project.yaml`) so that we can gradually enable
centipede later them later.

cgif: enable memory sanitizer (#9582 )

Enable memory sanitizer for [cgif](https://github.com/dloebl/cgif). I
already found one small issue testing it locally (timeout crash reported
by oss-fuzz):

```
$ ./build/fuzz/cgif_fuzzer_standalone clusterfuzz-testcase-cgif_fuzzer-6560939899224064

[cgif] Initial integration (#7321 )

Add initial [cgif](https://github.com/dloebl/cgif) integration.
[cgif](https://github.com/dloebl/cgif) is a GIF encoding library written
in C. It is used as the GIF encoding layer of
[libvips](https://github.com/libvips/libvips).
Right now, it is only fuzzed indirectly via
[libvips](https://github.com/libvips/libvips):
https://github.com/google/oss-fuzz/pull/6241
Fuzzing [cgif](https://github.com/dloebl/cgif) directly would allow
covering the complete API.

I would be happy to update this PR with the `Dockerfile` and `build.sh`
once I have the OK from your side.
