How to solve a broken pipeline in a merge request

In the GitLab Unfiltered video above, two colleagues share their screens and walk through the process detailed below.

If you create a merge request during a period where there is an issue in master causing pipelines to fail, you'll notice that failures will continue to occur even if you retry pipeline within the GitLab Web IDE interface.

Once the issue in master is fixed, you can solve this by using terminal to merge the latest version of master into your branch (which you can find in your merge request).

For those who primarily use Web IDE to interface with GitLab, it can feel foreign to engage locally. Before diving in deeper, be sure to read our GitLab 101 – a primer for the non-technical blog post.

The process is fairly straightforward once you have completed the necessary steps listed in the GitLab Handbook to edit locally.

Once you are properly equipped to edit locally, open a terminal window and execute the following.

Navigate to the appropriate project. If you've cloned the project to your root directory, try cd www-gitlab-com
git checkout master
git pull (This brings in the most recent changes from master to your local machine.)
git checkout MYBRANCH (Replace MYBRANCH with your branch from the merge request. This is easily copied by clicking the Copy Branch Name icon to the right of Request to merge at the top of your merge request page.)
git merge master (This takes the changes from master and merges them into your local MYBRANCH branch.)
:q (Entering :q followed by a Return keystroke quits vim which is the editor your terminal opened when adding the stock commit message to the merge.)
git push (This takes local machine files and pushes to the cloud.)

Once this has been executed, you'll see new commits added to your merge request, and the pipeline will automatically begin to re-run. If completed correctly, the pipeline will pass now that the latest master was merged into your branch.

If you are a GitLab team member and you get stuck, please ask for help in the #mr-buddies Slack channel.

Debugging a failed pipeline in the GitLab handbook

In the GitLab Unfiltered video above, Jean shares a quick overview of how to go about identifying why a pipeline might be failing for a merge request to the GitLab handbook.

Why is my pipeline failing?

If you've made a merge request, only to see that your pipeline has failed, a troubleshooting process begins.

You can learn more about why pipelines fail, what failures mean, and how to resolve conflicts by viewing this explainer video hosted on GitLab Unfiltered.

Where do I report handbook issues and request help?

Important Update

See Content Websites Responsibility for the latest information about the DRI and support processes for the about.gitlab.com site.

Reporting handbook issues and requesting help

For those inside the GitLab organization, you can request help on individual merge requests via Merge Request Buddies in the #mr-buddies Slack channel.

If you suspect a systemic issue, inquire in the #handbook-escalation Slack channel, and check to see if others are reporting similar errors in #is-this-known. For more information refer to the Handbook On-Call page.

The #handbook-escalation Slack channel is used for monitoring and responding to infrastructure and configuration related build issues with the www-gitlab-com project master branch. This is an excellent first stop to see if there is an ongoing issue impacting your pipeline.

The Editor Team is responsible for enhancing the editing experience for static sites inside of GitLab, including the handbook.

General GitLab handbook discussion occurs in the #handbook channel, while an automated feed of merged handbook updates can be found in the #handbook-updates channel.

Resolving linting errors

To the ensure consistency, quality and correctness of the GitLab Handbook we use various linting jobs that run as part of the pipeline. These jobs check that everything is as it should be, and if they detect something is wrong will cause the pipeline to fail.

Handbook Links and Anchors

There is a special linter that validates links and anchors across the handbook. If your change accidentally breaks a link, then the pipeline job will fail with a similar error message.

Link linter error

It is a path to the file where the broken link was detected. (filepath - sites/handbook/source/handbook/total-rewards/benefits/general-and-entity-benefits/pty-benefits-australia/index.html.md, line number: 87)
It is an error message. An anchor expense-reimbursement is defined in the file path from step 1 but does not exist in the file path from step 3.
It is a path where the header Expense Reimbursement needs to be defined. (file path - sites/handbook/source/handbook/spending-company-money/index.html.md)

How to fix the problem

Double-check that header Expense Reimbursement exists in sites/handbook/source/handbook/spending-company-money/index.html.md.

If it was moved or renamed, then update the link with the anchor to point to the correct location.

How to Find and Replace Content

There are times when you need to find every instance of a word, phrase or link and searching in the handbook online search field is too cumbersome or does not return accurate results. With an code editor and your terminal, you can find and replace content easily and quickly.

Terminal

Navigate to the appropriate project. If you've cloned the project to your root directory, try cd www-gitlab-com
git checkout master
git pull or git pull origin master (This brings in the most recent changes from master to your local machine.)
git checkout -b MYBRANCH (Replace MYBRANCH with the name of the branch you will be using for your merge request.)
Keep your Terminal window open, and now open your code editor (in this example, Visual Studio Code).

Visual Studio Code

Go to the Search section (View -> Search).
Type in the word, phrase or link you are searching for.
Type in the word, phrase or link you wish to replace it with in the Replace field, under the Search field.
Press the Replace All symbol at the end of the Replace field (or Option-Command-Enter).
You will get a pop-up asking you to confirm that you indeed with to Replace X occurence(s) accross X files with X ?. If correct, press Replace. Please note that it is possible to click on a search result to see individual changes and replace only a subset of all occurrences by clicking the replace button next to a given search result only.
Return to your Terminal.
