Capybara Webkit QT is just bullshit

06 Mar 2020 10:35

Capybara Webkit QT and annoyance.

An error occurred while installing capybara-webkit (1.8.0), and Bundler cannot continue.
Make sure that `gem install capybara-webkit -v '1.8.0' --source 'http://rubygems.org/'` succeeds before bundling.

In Gemfile:
  capybara-webkit

Bundle complete! 67 Gemfile dependencies, 216 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
Post-install message from sitemap_generator:
NOTE: SitemapGenerator 4.x uses a new file naming scheme which is more standards-compliant.
If you're upgrading from 3.x, please see the release note in the README:

https://github.com/kjvarga/sitemap_generator#important-changes-in-version-4

The simple answer is that your index file is now called sitemap.xml.gz
and not sitemap_index.xml.gz, but please take a look and see what else has changed.

npm start hangs on React Native boilerplate Expo app.

26 Nov 2019 06:06

Followed all the documentation to get this booted

Looking for JS files in
   /Users/cex/repos/GamingVideos 

Loading dependency graph, done.

It just hangs… This is apparently no that uncommon https://github.com/facebook/react-native/issues/25650 One suggestion is that node >= 12.5 has memory issues and that downgrading can help. I’m one of those people that tries to push the latest version of everthing and if you’ve ever dealt with huge amounts of legacy dependencies in Rails apps with lots of gem you’d probably agree this is mostly sane.

Not sure how you downgrade using Brew https://medium.com/@georgeenathomas/3-step-process-to-downgrade-node-version-using-homebrew-bc0b0a72ae27

New-MacBook-Pro:GamingVideos cex$ brew search node

==> Casks
nodebox                    nodeclipse                 soundnode

If you meant "node" specifically:
true

Seems like I have version 12 installed.

New-MacBook-Pro:GamingVideos cex$ brew unlink node
Unlinking /usr/local/Cellar/node/13.1.0... 7 symlinks removed
New-MacBook-Pro:GamingVideos cex$ brew link node@12

Well perhaps not…

######################################################################## 100.0%
==> Pouring node@12-12.13.1.mojave.bottle.tar.gz
==> Caveats
node@12 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.

If you need to have node@12 first in your PATH run:
  echo 'export PATH="/usr/local/opt/node@12/bin:$PATH"' >> ~/.bash_profile

For compilers to find node@12 you may need to set:
  export LDFLAGS="-L/usr/local/opt/node@12/lib"
  export CPPFLAGS="-I/usr/local/opt/node@12/include"

==> Summary
  /usr/local/Cellar/node@12/12.13.1: 4,225 files, 52.8MB

Now to relink it

New-MacBook-Pro:GamingVideos cex$ brew link node@12
Warning: node@12 is keg-only and must be linked with --force

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/usr/local/opt/node@12/bin:$PATH"' >> ~/.bash_profile
New-MacBook-Pro:GamingVideos cex$ brew link node@12 --force
Linking /usr/local/Cellar/node@12/12.13.1... 
Error: Could not symlink bin/npm
Target /usr/local/bin/npm
already exists. You may want to remove it:
  rm '/usr/local/bin/npm'

To force the link and overwrite all conflicting files:
  brew link --overwrite node@12

To list all files that would be deleted:
  brew link --overwrite --dry-run node@12

I’ve got to wing it here because I don’t know what is going to happen.

New-MacBook-Pro:GamingVideos cex$ brew link --overwrite node@12 --force
Linking /usr/local/Cellar/node@12/12.13.1... 3744 symlinks created

If you need to have this software first in your PATH instead consider running:
  echo 'export PATH="/usr/local/opt/node@12/bin:$PATH"' >> ~/.bash_profile
New-MacBook-Pro:GamingVideos cex$ node -v
v12.13.1

Looks like it’s done something right…. ok same damn thing. I am now going to nuke the project re-install everything and hopefully this time…

npm install -g expo-cli
expo init GamingVideos
cd GamingVideos
yarn android

Yeah….um…no.

Ok, followed that, now getting a error to do with missing licences. I couldn’t see a way on forcing licences to install. and checking in Android Studio I can see that Android 10.0 (Q) was installed. I selected Android 9.0 (Pie) just to see if it forced me to click yes on a licence agreement.

It didn’t but now yarn android on my project is doing something more.

Ok, so let’s start again on a different machine…and this is not making me happy. Documentation also says you can use npm start or expo start

Ok, so it was hanging because it needed permissions. Works. There was other wise nothing wrong at all. I love technology, it makes me happy.

Deploying application that includes Fog

I’ve deployed this app so many times and this time we’re missing libxml2

Deploying now…

I'm not angry but...

I spent much of yesterday trying to Paperclip working with some S3 extensions that I’ve used in countless projects and it just didn’t work. If you’re interested, well, here’s a slice of it.

module Paperclip
  module Storage
    S3.prepend(Module.new do
      def url(style_name = default_style, options = {})
        with_environment { super }
      end

      def expiring_url(time = 3600, style_name = default_style)
        with_environment { super }
      end
    end)
  end

  module Storage
    module S3
      def download_url(time = 3600, style_name = default_style)
        with_content_disposition("attachment; filename=#{instance_read(:file_name).without_extended_characters}") do
          expiring_url(time, style_name)
        end
      end

      def inline_url(time = 3600, style_name = default_style)
        with_content_disposition('inline') do
          expiring_url(time, style_name)
        end
      end

      private def with_content_disposition(disposition)
        @options[:s3_url_options] ||= {}
        @options[:s3_url_options][:response_content_disposition] = "attachment; filename=#{instance_read(:file_name).without_extended_characters}"
        yield
      ensure
        @options[:s3_url_options].delete(:response_content_disposition)
        @options.delete(:s3_url_options) if @options[:s3_url_options].empty?
      end

      # overrides s3 credentials to serve production assets when in
      # staging or development
      private def with_environment
        # only override if dev or staging
        return yield unless Rails.env.development? || Rails.env.staging?
        # only override if updated in the last day
        return yield if (instance_read(:updated_at) || 2.days.ago) > 1.day.ago

        begin

      end
    end
  end
end

With Settings to extract settings and cope with overriding different environments. Say, to display production images in development using the above. I’ve found it very useful.

module Settings
  def self.get(name, environment = Rails.env.to_s)
    fetch("#{name}.yml")[environment]
  end

  def self.fetch(config)
    yaml = paths(config).inject([]) do |yamls, path|
      yamls << IO.read(path)
    rescue Errno::ENOENT
      yamls
    end.reject(&:blank?).join("\n")

    if Rails.env.production? && yaml.include?('&defaults') && !yaml.include?("production:\n")
      yaml += "\nproduction:\n  <<: *defaults"
    end

    YAML.load(ERB.new(yaml).result)
  end

  def self.paths(config)
    [
      Rails.root.join('config', 'settings', config), # repo
      File.join(ENV['HOME'], application, 'shared', 'settings', config), # server
      File.join(ENV['HOME'], '.settings', application, config) # local
    ]
  end

  def self.application
    Rails.application.class.name.split('::')[0].underscore
  end
end

Except for yesterday when I forgot or didn’t realise that the storage option in Paperclip needs to be a symbol. If it’s a string it gets ignored.

def self.get(name, environment = Rails.env.to_s)
    fetch("#{name}.yml")[environment].deep_symbolize_keys # <---- hours wasted
  end

And finally the methods that extend Attachment::Storage::S3 don’t appear because it defaults to :filesystem unless you supply :s3 as a symbol. Ok, finally I am there… No.

AWS::S3::Errors::AccessDenied Access Denied

But I’ve added the Bucket Policy to use my IAM user, and set the correct permissions. I know this because I compared it to another policy I set up a week prior.

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::1234567890:user/username"
            },
            "Action": [
                "s3:ListBucket",
                "s3:GetBucketPolicy",
                "s3:PutBucketPolicy"
            ],
            "Resource": "arn:aws:s3:::bucketname"
        },
        {
            "Effect": "Allow",
            "Principal": {
                "AWS": "arn:aws:iam::1234567890:user/username"
            },
            "Action": [
                "s3:PutObject",
                "s3:GetObject",
                "s3:DeleteObject",
                "s3:PutObjectAcl"
            ],
            "Resource": "arn:aws:s3:::bucketname/*"
        }
    ]
}

Files didn’t upload at all. S3 credentials are correct. But still the same error. As then as it turns out, S3 buckets can be on this occasion was set to Bucket and Objects not public. So eventually I realise that the Paperclip upload default is :public and if I am trying to do that then I get AWS::S3::Errors::AccessDenied Access Denied sigh

defaults: &defaults
  storage: :s3
  bucket: bucket
  s3_protocol: :https
  s3_permissions: :private
  s3_credentials:
    access_key_id: accesskey
    secret_access_key: secretaccesskey
    s3_region: us-east-1

development:
  <<: *defaults

production:
  <<: *defaults
  bucket: bucket

So finally…at 2am. This is where we are. I enjoy the chase, I also enjoy sleep.

We need a name for our new board game

Ruby 1.8.7 and Rails 1.2

02 Oct 2019 09:12

We have recently been looking at hiring so I created a stupid question just to get a developer talking. When I first started working with Rails we were building Euro-reg.com with Ruby 1.8.6 and Rails 1.2.3 as far as I can recall. So the question ended up being…

Suppose we hired you and on day one said we have this Rails 1.2 Application on Ruby 1.8.7, using SQLite in production that is mission critical. How would you approach bringing it up to date?

Some feedback we got was “…Rails v1.0—2.1 are incompatible with Ruby v1.8.7…” which made me question my stupid question. Actually it’s been so long I can’t even remember. So 10 minutes later.

The flow was

install 1.8.7 under rvm
this installs Rubygems 2.0, so you need to revert that to 1.8
edit config/boot.rb and replace require_gem with gem

That was nicely quick, I guess it could have been horrible.

Want to find files with exactly the right size

01 Aug 2019 01:44

Have you ever come across some files in your application that just appear to be generated by err…..a generator and actually do nothing. Well I find a couple of javascript files with the same content (and therefore the same size) and wondered if there were any more.

# Place all the behaviors and hooks related to the matching controller here.
# All this logic will automatically be available in application.js.
# You can use CoffeeScript in this file: http://jashkenas.github.com/coffee-script/

Well fortunately you can use find with a specific option

Robs-MBP:blah rl$ find app/assets/ -size 229c
app/assets//javascripts/some.js.coffee

Excellent, I can ditch that file too then.

HAML whitespace

17 Mar 2019 19:28

I came across a weird HAML syntax in a client codebase that I was just confused about.

Haml::Engine.new(%q{
- title = '1'
.title== #{title}<br/>
}).to_html
=> <div class='title'>1<br/></div>

I found an alternative syntax, I am not sure I like it but it’s certainly better than the above.

Haml::Engine.new(%q{
- title = '1'
.title<
 #{title}
 %br>
}).to_html
=> <div class='title'>1<br></div>

Basically you can kill whitespace with < >

Bundle deprecations

If you want to search your bundle for anything in particular, in this case the deprecated Digest::Digest syntax
