Patching files via composer using bitbucket pipelines

Christian Biggins

I have a very simple pipelines, I am just trying to get the app to build before I look to adding anything else to it. But, even in its simple state, I can't get composer to successfully patch a file. The entire composer install works flawlessly until this point:

  - Applying patches <span>for</span> drupal/core
    https:<span>//www.drupal.org/files/issues/2021-03-05/3007386-language-negotiator-weight-12.patch (Language negotiation weight)</span>
   Could not apply patch! Skipping. The <span>error</span> was: Cannot apply patch https:<span>//www.drupal.org/files/issues/2021-03-05/3007386-language-negotiator-weight-12.patch</span>
                                                                                                                                                
  [<span>Exception</span>]                                                                                                                                   
  Cannot apply patch Language negotiation weight (https:<span>//www.drupal.org/files/issues/2021-03-05/3007386-language-negotiator-weight-12.patch)!  </span>

After it started failing, I added some debug to the config including trying to cat the file that was to be patched, but it is not there.

+ cat docroot/core/modules/language/src/LanguageNegotiator.php
cat: can<span>'t open '</span>docroot/core/modules/language/src/LanguageNegotiator.php<span>': No such file or directory</span>

This is the composer patch chunk:

  <span>"extra"</span>: {
    <span>"patches"</span>: {
      <span>"drupal/core"</span>: {
        <span>"Language negotiation weight"</span>: <span>"https://www.drupal.org/files/issues/2018-10-17/3007386-language-negotiator-weight-2.patch"</span>
      }
    },

This is the pipeline yml:

<span># Template PHP Build</span>

<span># This template allows you to validate your PHP application.</span>
<span># The workflow allows running tests and code linting on the default branch.</span>

image: php:<span>7.3</span>-alpine

pipelines:
  <span>default</span>:
    - parallel:
        - step:
            name: Prepare environment
            script:
              - /sbin/apk update
              - /sbin/apk add git
              - curl -sS https:<span>//getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer</span>
              - docker-php-ext-install mysqli pdo pdo_mysql
              - /sbin/apk add libpng-dev
              - docker-php-ext-install mbstring
              - docker-php-ext-install gd
              - pwd
              - ls -la
              - cat docroot/core/modules/language/src/LanguageNegotiator.php
              - /usr/local/bin/composer install
            caches:
              - composer

Do I need to change directories or do something similar?

Hi @Christian Biggins

Thank you for reaching out to the community.

Based on the error message, it appears the patch is not being skipped.

To debug it further, would it be possible for you to test your Pipelines build locally in a Docker container?
Ideally, if it works locally, it should also work on Pipelines.

Let me know how it goes.

Regards,
