[ Repo auth ] Fails to build a byte code repository on hhvm 4.168+

[lexidor]

Describe the bug When trying to build a byte code repository in docker, hhvm 4.168 fails with a set_mempolicy: Operation not permitted

Standalone code, or other way to reproduce the problem

<<__EntryPoint>>
function main(): void {}

hhvm.repo.authoritative=true
hhvm.repo.path=./hhvm.hhbc
hhvm.server.allow_run_as_root=true

Steps to reproduce the behavior:

1. Create an empty Hack project in an hhvm/hhvm docker container
2. Add an empty hhconfig file.
3. Put an empty entry point, as shown above in src/main.hack
4. Put the INI file shown above in repo-auth.ini
5. Create a repo using hhvm --hphp --input-dir $(pwd) --output-dir .
6. When running under hhvm/hhvm@4.167-latest, observe a successful creation of hhvm.hhbc in the project directory.
7. Run the server using hhvm -m server --no-config -c repo-auth.ini
8. Curl (with option verbose flag) localhost from within the container. Observe an HTTP 200 without content.

Expected behavior

As described in steps to reproduce

Actual behavior

Step 5. fails with the following error:

...
Extern worker error while indexing: Execution of `hphpc-index` failed: exited with status 1
stderr:
set_mempolicy: Operation not permitted
...

Environment

• Operating system

  Host system Ubuntu 22.04.

• Installation method

  hhvm/hhvm on dockerhub

• HHVM Version

  4.168.0, as provided in the docker container

Additional context I did already change the commands to be compatible with the removed cli flags from hhvm 4.167.0.

Is it a docker specific problem? Did you test repo mode without a docker container?

[Atry]

Looks similar to the CI failures in https://github.com/hhvm/hacktest/pull/115/files

[Atry]

This is not a docker specific problem. I can reproduce it without a docker container.

[Atry]

I can also reproduce it with the nix based universal HHVM deb package

[Atry]

I cannot reproduce this issue with a HHVM built from clang.

[Atry]

As a workaround, you can use the HHVM package built from clang to use repo auth.

You can find the instruction to install hhvm_clang packages at https://github.com/hhvm/user-documentation/pull/1295

The nightly version 2022.09.01 is good to use repo mode, while the nightly version 2022.09.02 is not.

The failure seems related with 280e6899b442796a197b5b236d3ddd50d0b62b5f.
