Use snap driver when chromium is installed via snap package

Open mdesantis opened this issue 3 years ago • 15 comments

Summary

The downloaded chromedriver doesn't work with Chromium installed via snap package (as written here: https://github.com/titusfortner/webdrivers/wiki/Chrome-snap-package-hangs).

The solution pointed in the wiki suggests installing Chromium via apt, but it isn't an easy option as Ubuntu doesn't provide an apt flavour of Chromium and the unofficial alternatives are unreliable (for example, the one linked in the issue related to the wiki page is marked as abandoned: https://launchpad.net/~xalt7x/+archive/ubuntu/chromium-deb-vaapi).

Anyway, The snap flavour of chromedriver works fine together with snap Chromium. So I suggest to detect that Chromium is installed via snap (I guess it is possible to check that the Chromium path starts with /snap/) and, in this case, skip chromedriver installation and use the snap chromedriver (or tell the user to install it). I'm open to work on a pull request, if welcome.

My current workaround is to overwrite the chromedriver path set by webdrivers:

::Selenium::WebDriver::Chrome::Service.driver_path = proc { '/snap/bin/chromium.chromedriver' }

Debug Info

  • Webdrivers version: 4.6.1
  • Ruby version: 3.0.2
  • Operating system / CI Environment: Linux Ubuntu 20.04.2
  • Browser and version:
    • Chromium 93.0.4577.82 snap
    • ChromeDriver 93.0.4577.82 (e3a25d9b9e2d0b728e045ec87c0aa4942aa46e4e-refs/branch-heads/4577@{#1237})

Expected Behavior

I expect Webdrivers to detect that Chromium is installed via snap and to set the related chromedriver accordingly, rather than downloading and hanging during tests running.

Actual Behavior

Well, I guess I can write here the error log when using snap Chromium together with the downloaded driver:

Can you set the desired location of your Chromium binary with: ENV["WD_CHROME_PATH"]

titusfortner avatar Oct 14 '21 23:10 titusfortner

I have the same issue. I tried setting WD_CHROME_PATH to /snap/bin/chromium.chromedriver', '/snap/bin/chromium' and '/snap/bin/' with equally poor results.

Seems that the only way to get it to work was setting the driver_path to the chromium.chromedriver that was installed with snap install chromium.

@entretechno-jeremiah re: #225

Can you set Selenium::WebDriver::Chrome.path = "/snap/chromium/current/usr/lib/chromium-browser/chrome" and see if the driver downloaded by webdrivers works? The problem in the original issue (#168) was that chromium was hanging when webdrivers tried to retrieve its version. I don't have a linux machine at hand to test this, but I think chromedriver itself should work and not be the problem here. It's the wrapper which was problematic and the using the underlying binary worked when I tried.

In any case, I am not keen on merging #225 in its current form because it's adding browser specific logic in Common#update. If the above doesn't work then we're pretty much looking at overriding what webdrivers is at its core and blindly returning whatever driver we find in /snap/bin without performing any compatibility checks, which is oof...

@kapoorlakshya

Can you set Selenium::WebDriver::Chrome.path = "/snap/chromium/current/usr/lib/chromium-browser/chrome" and see if the driver downloaded by webdrivers works?

That works! If I submitted a PR to set Selenium::WebDriver::Chrome.path = ENV['WD_CHROME_PATH'], how would you feel about that? I understand if that's maybe not the concern of this library.

entretechno-jeremiah avatar Jan 21 '22 16:01 entretechno-jeremiah

@entretechno-jeremiah Great! How about you just set WD_CHROME_PATH=/snap/chromium/current/usr/lib/chromium-browser/chrome in your dev/test environment so webdrivers can read the product version from that binary and download a compatible driver. Selenium can continue to use the wrapper/shim from snap and everything should work as expected.

kapoorlakshya avatar Jan 21 '22 22:01 kapoorlakshya

@kapoorlakshya I thought I had tried that and it didn't work; but I tried it again and it does work. Sorry about that! And thanks for all your help!

entretechno-jeremiah avatar Jan 21 '22 22:01 entretechno-jeremiah

@entretechno-jeremiah No problem! Glad we figured it out.

@mdesantis @pgwillia Please give the above a try and confirm if it works for you as well. I'd like to close this ticket and document the workaround in the wiki once we have multiple confirmations. Thanks!

kapoorlakshya avatar Jan 21 '22 22:01 kapoorlakshya

@kapoorlakshya Sorry again; I was right the first time that it didn't work. I had made a change to my local version of this library and forgot about it before I re-ran my tests. So setting WD_CHROME_PATH by itself does not work; it only works if I also set Selenium::WebDriver::Chrome.path. Once again sorry for the back-and-forth.

I've spent a lot of time looking at this over the past few days, and I think this is due to much deeper problems with the Chromium Snap package or Snap itself (as discussed in #168). Until that's fixed (:crossed_fingers:), I'm going to use this hacky workaround:

sudo ln -s /snap/chromium/current/usr/lib/chromium-browser/chrome /usr/local/bin/google-chrome

This works because /usr/local/bin is one of the directories in which chromedriver looks for a binary (gotta love that // TODO: Respect users' PATH variables. :sweat_smile:) and google-chrome is one of the binary names it looks for (this is what Webdrivers::ChromeFinder is based on). I don't have any existing google-chrome binaries in my PATH, which leads me to believe that would only happen if you install Chrome instead of Chromium; so hopefully the only outcome of creating that symlink is tricking chromedriver into using that instead of /snap/bin/chromium. I haven't noticed any problems so far; I'm still able to use Chromium normally.

@kapoorlakshya How would you feel about a PR to set a WEBDRIVERS=1 env var when this launches chromedriver so that I could replace that symlink with a script that conditionally executes the right binary depending on whether it was called via this library or not? That way we hopefully wouldn't have to worry about any side effects of that symlink, and you could document it as an official workaround (pending confirmation from other users). Thanks again for all your work on this!

entretechno-jeremiah avatar Jan 23 '22 02:01 entretechno-jeremiah

@entretechno-jeremiah No worries, happy to keep troubleshooting.

So setting WD_CHROME_PATH by itself does not work;

Did it hang or was there an error?

I like the symlink idea, but I am not sure if setting ENV['WEBDRIVERS'] =1 from webdrivers will make it available to contexts outside of it (i.e. your script). My understanding is that it will only set it for the ruby process that sets is. Can you give it a try and report back if it works? I don't see any harm in setting that env var if it helps resolve this issue.

kapoorlakshya avatar Jan 23 '22 03:01 kapoorlakshya

So... I just set up WSL2 w/ Ubuntu 20.04.3 to reproduce this issue and I am no longer able to. Chromium (installed via snap) returns the version without hanging and chromedriver is successfully downloaded.

It hangs - not when getting the version as originally reported, but when actually running the tests and when attempting to exit the browser. I've created entretechno/webdrivers-217 as a test case for this; here's the output of bin/rails test:system:

entretechno-jeremiah avatar Jan 24 '22 03:01 entretechno-jeremiah

@entretechno-jeremiah Interesting... I think that since webdrivers is able to do its job successfully, solving what you're seeing would fall outside the scope of this gem.

Can you please remind me why we can't just set Selenium::WebDriver::Chrome.path = '/snap/chromium/current/usr/lib/chromium-browser/chrome' in your tests to make them work? webdrivers shouldn't need anything special now that it's able to successfully use /snap/bin/chromium. Right?

kapoorlakshya avatar Feb 03 '22 05:02 kapoorlakshya

If you already know the path to an existing driver that you want to use, you can pass it in to Selenium's Service class and it will ignore webdrivers gem entirely.

Can re-open if an alternate use case is provided.

titusfortner avatar Aug 12 '22 13:08 titusfortner

This gem is generally consistent in approach between different browsers/drivers/platforms. Anything done in the gem to accommodate a custom browser implementation that has a custom driver is going to be a hack.

Whether to support a hack at all mostly comes down to how many people need it, and based on the conversations it appears this is a sufficiently popular request.

If someone wants to make a PR to subclass the #update method for Chrome to check if it's a snap installation and return the full path of the snap driver, I'll merge it.
