Build seems to be stuck on Netlify

[thbar]

Hello!

Thanks for your gem. I was trying to use the latest version (0.3.0) on netlify, but apparently the build never returns.

If I remove the gem completely (from both Gemfile and Jekyll config), the build works fine.

I wonder if this is related to the changes in v0.3.0 (tcp server) which may be forbidden there.

I will investigate further (and will try older version), but wanted to report that.

Thanks for the bug report!

I think the tcp server should be fine, but I’ll give it a look. I haven’t deployed my blog yet with this update, so maybe that’s why it slipped through.

[thbar]

Thanks for the quick reply! Reverting to previous version seems to work, if I'm not mistaken and fwiw!

[mhanberg]

Do you mind sharing

• the tail of the log where it’s blocked
• ruby version
• node version
• jekyll version
• build command

Thanks! @thbar

The tail of the log looks like this:

6:31:04 PM: Verify run directory
6:31:04 PM: Executing user command: bundle exec jekyll build
6:31:04 PM: Configuration file: /opt/build/repo/_config.yml
6:34:31 PM: Canceling deploy

(Canceling is triggered by me). This must be compared to this when a full build works (with previous version:

6:50:19 PM: Verify run directory
6:50:19 PM: Executing user command: bundle exec jekyll build
6:50:20 PM: Configuration file: /opt/build/repo/_config.yml
6:50:20 PM:             Source: /opt/build/repo/src
6:50:20 PM:        Destination: /opt/build/repo/_site
6:50:20 PM:  Incremental build: disabled. Enable with --incremental
6:50:20 PM:       Generating...
6:50:26 PM:                     done in 5.996 seconds.
6:50:26 PM:  Auto-regeneration: disabled. Use --watch to enable.

Ruby version: 2.6.2 (to accelerate build on Netlify, where it is apparently the default, but 2.6.6 will achieve the same result)

Node version: v12.16.1

Jekyll: 4.0.1

Build: bundle exec jekyll build

Hope this helps!

Thanks, I've confirmed this with my own blog.

My hypotheses are there is some path shenanigans going on, or some Node.js sandboxing of which I am unaware.

I've opened a topic on the Netlify discourse: https://community.netlify.com/t/deploy-is-hanging/14822

[thbar]

I would be surprised if Netlify doesn't block TCP socket opening, or at least restrict it:

v0.2.2...v0.3.0#diff-b7eb3592a63ae055d731d361a948afbfR17-R24

I would probably add a log in that silent rescue ;-)

Good luck chasing that, I'll comment back if I find something!

Link correction:

jekyll-postcss/lib/jekyll-postcss/socket.rb

Lines 16 to 23 in 5cf6d99

	@postcss = nil
	while @postcss.nil?
	begin
	@postcss = TCPSocket.open("localhost", 8124)
	rescue StandardError
	nil # Suppressing exceptions
	end
	end

If I add a log there, it will print out about 5000 lines haha.

The server is misty a dev convenience. In production it might be easier to just run it directly.

[thbar]

Ahh! I see, indeed. Maybe add a little delay, and a limit to the loop? An explanation could be that the code never leaves that loop!

[thbar]

In all cases, thanks for your gems & also starter kits, because I migrated my little website (at https://www.kiba-etl.org) from raw pages with tailwind to Jekyll, and it was helpful!

[mhanberg]

The fixed has been released with v0.3.1!

[thbar]

@mhanberg thanks for the quick turn-around. I've tested and indeed it works for me. Many thanks!

I think this needs to be more stressed. I figured the reason you mentioned it is that you're using the env variable in the postcss config on your demo repo only. I didn't realize it would hang in netlify and y local docker env.

[mhanberg]

@steveoh I will update the README to further highlight the requirement to set the JEKYLL_ENV on your build server, but I will note that it currently states that your build might fail if you don't set it.

[steveoh]

failing and hanging are a little different. I thought it might be taking a while to process since we have 500 pages. but you are right, you did mention that.
