libvips-segfault-repro's Introduction

SEGFAULT Reproduction

This issue only arises after the addition of FFI::shutdown() in index.php however if you don't call the shutdown function the memory used by the container accumulates - usually until it is killed.

docker build -t libvips-segfault-repro .

docker run -it --rm -p 8000:80 libvips-segfault-repro

Run apachebench to make some volume of requests or just keep hitting refresh in a browser ab -n 100 -c 5 http://localhost:8000/

Watch the output from the container and observe the SEGFAULTS

If you want to run the container with the local volume mounted run composer install and mount the current working dir to /var/www

docker run -it --rm -v $PWD:/var/www -p 8000:80 libvips-segfault-repro

libvips-segfault-repro's Issues

mr-depp can't solve composer dependencies

composer reported the following solving error when mr-depp tried to update your dependencies:

Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Root composer.json requires jcupitt/vips ^2.1 -> satisfiable by jcupitt/vips[v2.1.0].
    - jcupitt/vips v2.1.0 requires ext-ffi * -> it is missing from your system. Install or enable PHP's ffi extension.

To enable extensions, verify that they are enabled in your .ini files:
    - /usr/local/etc/php/php-cli.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-bz2.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-zip.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-ffi` to temporarily ignore these required extensions.

Some suggestions:

  • Do you use private repositories? Make sure they're configured - along with any credentials - in your composer.json
  • mr-depp uses an emulated php environment : have you specified the right php version and any extensions required in your platform config?

Use composer show --platform to see the php version and extensions installed in your project's runtime environment,
and composer check-platform-reqs to see the constraints that are actually required.
