bun run build fails to complete

[azliu0]

Description

bun run build fails to complete in gVisor with Next.js version 14.2.20.

There are already some known incompatibilities with Bun and gVisor. For example, Bun implements a workaround for the missing pidfd API in gVisor (#5839). To try to address this incompatibility, I've partially implemented the api here: master...azliu0:gvisor:azliu/pidfd_open. This patch implements pidfd_open, which is the only syscall in the pidfd api used by bun; see here.

Unfortunately, even with this patch, the reproduction script below still fails, which leads me to believe that something else may be going on. I can't be sure that this is only a gVisor issue, so I've also opened oven-sh/bun#16063. The reproduction script works with runc so it seems likely there's still something wrong with gVisor.

Steps to reproduce

Dockerfile:

FROM oven/bun:latest

RUN apt-get update -yqq && \
    apt-get install -yqq git && \
    bun install -g turbo

WORKDIR /march
RUN git clone --depth 1 https://github.com/marchhq/march.git . && \
    git fetch --depth 1 origin c0f0d196c4f7f94e10a66747be9bf96ce0135967 && \
    git checkout -f FETCH_HEAD
RUN bun install
CMD ["bun", "run", "build"]

Then build the image and run with runsc.

Expected behavior: bun run build finishes relatively quickly.
Observed behavior: bun run build hangs at the step Generating static pages (21/21).

On the patched version that implements pidfd_open, I also observe bun run build hanging after a certain point, but the output looks different. A caveat is that the implementation in this patch may be incorrect, but it at least passes the tests in test/syscalls/linux/pidfd.cc.

I observe the expected behavior with runc.

i pulled the pidfd patch and i reproduced the issue. It hangs before it started the build steps to Generating static pages

~/workspace/experiment/bun$ docker run --runtime=bunbun-d --rm buntest

From the debug logs, the runsc seems to be stuck at

The same behavior can also be seen at KVM platform. it is less likely a platform issue

wow, I can actually finish the build w/o the pidfd patch

i would recommend to use a newer version of runsc and give it try again.

what i have done differently is that i used the runsc i built from HEAD

[azliu0]

@milantracy thanks for looking into this! Are you able to finish the build consistently? I'm running the latest version of master locally and still seeing the build hang, although this is non-deterministic.

[milantracy]

I have not seen any inconsistent behavior, I run the bun build 10 times in a row, it works for me,

jing@dev ~/workspace/gvisor (runsc) $ for i in {1..10}; do
  time docker run --runtime=runsc --rm buntest  &> /tmp/buntest.log
done

docker run --runtime=runsc --rm buntest &> /tmp/buntest.log  0.01s user 0.02s system 0% cpu 2:20.35 total
docker run --runtime=runsc --rm buntest &> /tmp/buntest.log  0.01s user 0.02s system 0% cpu 2:20.89 total

docker run --runtime=runsc --rm buntest &> /tmp/buntest.log  0.01s user 0.01s system 0% cpu 2:20.57 total

and my kernel version is

jing@dev ~/workspace/gvisor (runsc) $ uname -a

and runsc version is

    Kubernetes benchmarks: Refactor kubectl context to allow sets of clusters.
    
    Also add sanity check to make sure each cluster works as part of
    initialization, by running a sample pod within.

my runtime config at /etc/docker/daemon.json is

        "runsc": {
            "path": "/tmp/runsc/runsc",
            "runtimeArgs": [
                "--debug-log",
                "/tmp/runsc/logs/runsc.log.%TEST%.%TIMESTAMP%.%COMMAND%",
                "--net-raw"
            ]
        },
        "runsc-d": {
            "path": "/tmp/runsc/runsc",
            "runtimeArgs": [
                "--debug-log",
                "/tmp/runsc/logs/runsc.log.%TEST%.%TIMESTAMP%.%COMMAND%",
                "--net-raw",
                "--debug",
                "--strace",
                "--log-packets"
            ]
        },

[azliu0]

Hm, this is tricky. My local setup looks the same. I've reran these steps from scratch, and unfortunately am still seeing the hang:

• create fresh instance with type m6id on AWS
• install make, docker, and other deps to build and run gvisor
• git clone https://github.com/google/gvisor
• cd gvisor && make dev

My runtime config at /etc/docker/daemon.json after running these steps looks like this:

        "master": {
            "path": "/tmp/master/runsc",
            "runtimeArgs": [
                "--debug-log",
                "/tmp/master/logs/runsc.log.%TEST%.%TIMESTAMP%.%COMMAND%",
                "--net-raw"
            ]
        },
        "master-d": {
            "path": "/tmp/master/runsc",
            "runtimeArgs": [
                "--debug-log",
                "/tmp/master/logs/runsc.log.%TEST%.%TIMESTAMP%.%COMMAND%",
                "--net-raw",
                "--debug",
                "--strace",
                "--log-packets"
            ]
        }

I've rerun these steps from scratch on a fresh instance, and I still reliably observe a hang at the step @march/frontend:build: ✓ Generating static pages (21/21) after re-running docker run --runtime=master --rm buntest a few times.

Could you upload the debug log files generated in /tmp/master/logs/ after one of these runs which hang? Please note that it will continue to accumulate log files from previous runs. So please clear /tmp/master/logs/ before each run and upload all the files generated by the failing run.

Please use the runtime master-d, as it includes more debug output.
