Open infl-herman opened 1 year ago

infl-herman commented 1 year ago

Describe the bug you encountered:

Getting segmentation fault when running Pyroscope on a Rails app

What did you expect to happen instead?

No Segementatin fault

How did you install pyroscope-rs?

Using a Gemfile

gem 'pyroscope', '~> 0.4.0

pyroscope-rs version and environment Gem version installed: 0.4.0, running on a docker image, here is the docker file on the base image.

FROM ruby:2.5.5

RUN apt update -y && apt install -y \
  dnsutils \
  less \
  tzdata \
  libxml2-dev \
  libxslt1-dev \
  libstdc++-8-dev \
  imagemagick \
  potrace \
  postgresql-client \
  postgresql \
  file \
  libxml2-dev \
  libxslt-dev \
  linux-libc-dev \
  sqlite3 \
  libsqlite3-dev

RUN bundle config build.nokogiri --use-system-libraries

this is the app's docker file

FROM <company docker registry>/docker/ruby:2.5.5

WORKDIR /usr/src/app

RUN apt update -y && apt install -y shared-mime-info musl-dev
RUN ln -s /usr/lib/x86_64-linux-musl/libc.so /lib/libc.musl-x86_64.so.1

ENV BUNDLE_PATH=/opt/bundle \
    BUNDLE_DISABLE_SHARED_GEMS='1' \
    PATH="/opt/bundle/bin:${PATH}"

and here is the segfault info we get when we run our rails app:

The PGconn, PGresult, and PGError constants are deprecated, and will be
removed as of version 1.0.

You should use PG::Connection, PG::Result, and PG::Error instead, respectively.
