@DonggeLiu I have big troubles getting the benchmarks working.

locally for me everything compiles fine, e.g. re2_fuzzer:

$ make test-run-aflplusplus_early-re2_fuzzer
docker build \
--tag gcr.io/fuzzbench/builders/benchmark/re2_fuzzer \
--build-arg BUILDKIT_INLINE_CACHE=1 \
--cache-from gcr.io/fuzzbench/builders/benchmark/re2_fuzzer \
--file benchmarks/re2_fuzzer/Dockerfile \
benchmarks/re2_fuzzer
[+] Building 12.2s (12/12) FINISHED                              docker:default

but when building here I get

Step #2 - "aflplusplus_early-re2_fuzzer-builder-intermediate": #7 ERROR: executor failed running [/bin/sh -c apt-get install -y lsb-release software-properties-common gnupg wget]: exit code: 100

ERROR: build step 2 "gcr.io/cloud-builders/docker" failed: step exited with non-zero status: 1
------------------

and that makes no sense because for one fuzzer the same two targets always build on fuzzbench (ossfuzz, openh264), and all other fail. but the other fuzzer instance succeeds in all targets. and the only difference between the two in builder.Dockerfile is:

do you have any idea what is going wrong?
btw. you can kill all afl++ fuzzing instances ...

Could flaky network issues cause this?

In the past, I recall seeing apt-get fail due to a network problem and then work again after a few hours in CI tests.
Maybe re-try it in a few hours and see if it occurs again?

[vanhauser-thc]

I have this issue since Friday. And if it would be a network issue it would affect both fuzzers and random targets

[vanhauser-thc]

And you can see it works in the ci too - it’s green for most

I see. That's strange because I don't recall changing anything related last week.
Unfortunately, I will need more time before I can debug this because I am currently occupied by other tasks.

For now, I can:

1. Cancel all AFL++ experiments, and
2. Re-launch the experiment here, just in case my account makes any difference (which is unexpected).

Meanwhile, I guess two potential ways may help us understand this error better:

1. Split the apt-get command and install one package in each. This helps us see which one caused the failure.
2. Add apt-get update && before the apt-get that caused the error. This should be unnecessary because your first RUN command already did it, but it can at least rule out a possibility.

[vanhauser-thc]

Same in your run. Ci is green for the targets, but for the fuzzing the same fuzzer only one target built successfully :(
And only half of the targets are there. Weird.

the test is important because this is testing a major change for llvm 16+ and we need a release very soon

@DonggeLiu it worked when I switched to llvm 16 (or the issue just dissolved for other reasons). trying llvm 19 now.

[jonathanmetzman]

I'm guessing the differences between this happening in prod vs local are because of caching.
I agree with Dongge that the issue looks like it is caused by not having apt-get update && before apt-get install

@jonathanmetzman this is what I meant with the issues I have on fuzzbench:

Everything built fine for https://www.fuzzbench.com/reports/experimental/2024-05-23-aflpp/index.html

in https://www.fuzzbench.com/reports/experimental/2024-05-24-aflpp/index.html I didn’t change these but added two more. The ones I added are fine but the original two now have one target that didn’t built.

I didn’t check the build logs what exactly went wrong but either way it is something that fuzzbench should detect and retry, wiping a cache beforehand etc or whatever is causing this.
