Failed to print using chromium=128.0.6613.84-1~deb12u1 #326

Hey there!!

I see nice improvements in the library! Thanks a lot!

I was releasing a new version of my app today (with Chromic 1.17) and saw that all PDF rendering started to crash.. After trying to rollback Chromic's version and seeing that it wasn't the problem, I looked at the difference between both docker images.. the chromium package's version!

I also build locally and for 128.0.6613.84-1~deb12u1, all my renders fail with the following error:

[0826/154642.416085:ERROR:file_io_posix.cc(145)] open /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq: No such file or directory (2)

Chrome has responded with the above error error while you were trying to print a PDF.

15:46:42.426 [error] ChromicPDF received an 'Inspector.targetCrashed' message.

This means an active Chrome tab has died and your current operation is going to time out.

Known causes:

1) External URLs in <link> tags in the header/footer templates cause Chrome to crash.
2) Shared memory exhaustion can cause Chrome to crash. Depending on your environment, the
   available shared memory at /dev/shm may be too small for your use-case. This may
   especially affect you if you run ChromicPDF in a container, as, for instance, the
   Docker runtime provides only 64 MB to containers by default.

   Pass --disable-dev-shm-usage as a Chrome flag to use /tmp for this purpose instead
   (via the chrome_args option), or increase the amount of shared memory available to
   the container (see --shm-size for Docker).

Not sure if the error message helps here a lot.. Any idea why this could be happening??

Thanks in advance!!

For what it's worth, starting at least a week ago, my Phoenix app with chromic_pdf and headless chrome embedded won't event start up. Somehow the buildpack I am using on Gigalixir grabbed the same version of Chrome as the OP; 128.0.6613.84, and now my app won't start properly. In some cases it refuses connections on port 4000. In other cases it just restarts over and over.

My logs are different than the OP, however. There's a lot of this:

ERROR:zygote_host_impl_linux.cc(99)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180

If this happens at startup and you are running inside a Docker container with a Linux-based
If this happened while you were printing a PDF, this may be a problem with Chrome itelf.
Either way, to see Chrome's error output, configure ChromicPDF with the option
discard_stderr: false
** (ChromicPDF.Connection.ConnectionLostError) Chrome has stopped or was terminated by an external program.

I tried removing the warm_up code. I also tried setting no_sandbox to both true and false, but nothing works.

It seems pretty clear that this is a change in Chrome and not in ChromicPDF, but maybe you can find a workaround.

petelacey commented 2 weeks ago

As a follow up. I changed the application.ex file to start up ChromicPDF as follows:

      {ChromicPDF,
        [
          no_sandbox: true,
          discard_stderr: false,
          offline: true,
          session_pool: [init_timeout: 10_000, size: 5],
          disable_scripts: true,
          chrome_args: [
            append: "--headless=new",
            remove: ["--headless"]
          ]
        ]
      },

Again, this is in the Gigalixir PaaS. It's running Heroku's buildpack heroku-20 (Ubuntu 20). I also upgraded to ChromicPDF 1.17.0. And I changed to this Chrome buildpack: https://github.com/heroku/heroku-buildpack-chrome-for-testing

I don't know if any of that helps, but if you have any thoughts, I'm all ears. Thanks!!!

A few more bits of information, if you don't mind. It appears that after I (reluctantly) turned no-sandbox on, the app does indeed startup and I can generate PDFs as before. It's just that all that :point_up: crazy stuff gets dumped into my logs first.

Incidentally, I put back the call to warm_up which I had previously removed, but that changed nothing. And I tried headless=old too, but that didn't change anything either. And finally I upgraded from Ubuntu 20 to 24, but again, nothing.

Something changed in Chrome between versions 127 and 128 that just made everything go sideways, and I don't see any way to pin the Chrome buildpack I'm using to a certain chrome version, it's always going to pick the current stable release. :disappointed:

Hey @petelacey. I ran into the same issue. For me, it seemed to be large images being displayed as base64 data. 127 was fine, and 128 crashed intermittently.

I forked the "old" chrome buildpack and added the ability for it to read a GOOGLE_CHROME_MAJOR_VERSION environment variable. I've got mine set at 127 for now and it seems to be working. Feel free to use / fork (at your own risk) of course 😅

petelacey commented 2 weeks ago

Thanks, @metabren!!! You, sir, are a marvel. I didn't even think this was a possible. For now, I've temporarily pivoted over to a wkhtmltopdf solution (my PDF needs are modest), but I will definitely try this out next week.

maltoe commented 1 week ago

Hello both,

thank you for the information. Unfortunately, I don't have much time to look into it further. But considering there are possibly related active issues in other repositories, this may as well be a Chromium bug and we only need to give upstream some time.

@andreasknoepfle Confirmed this is an issue for Alpine-3.20 based images, see https://gist.github.com/maltoe/dcc697f17b92bb1911b74a44d534b5b9 (124 works, 128 crashes)

metabren commented 1 week ago

Apologies @maltoe, I should have said. I definitely would consider this a Chromium bug. Hope they sort it out soon.

petelacey commented 1 week ago

Thanks, @maltoe. I was able to get past this with @metabren's buildpack. I'll make a point of trying upcoming releases of chrome. I'll leave a note when it starts working again.
