How to enable case sensitivity for a repository in Azure Repos?

The Windows and macOS file systems are case-insensitive (but case-preserving) by default. Most Linux filesystems are case-sensitive. Git was built originally to be the Linux kernel’s version control system, so unsurprisingly, it’s case-sensitive. While many of the issues with a case-insensitive OS have been addressed in Git for Windows, a few quirks remain.

File and folder names

On Linux, checking out a Git repo which contains both “File.txt” and “file.txt” is no problem. Those are distinct filenames. On Windows and macOS, checking out both files will result in the second one overwriting the first one. If two folders differ only by case, their contents will end up mixed together on case-insensitive filesystems.

Branch and tag names:

You can create two branches or tags (known as ‘refs’) that differ only in casing. Git’s internals, as well as Azure DevOps Services/TFS, will treat them as two separate refs. On a user’s machine, Git uses the filesystem to store refs. Fetches and other operations begin to fail because of the ambiguity. Each ref is represented by a small file, and if a ref name contains / characters, the parts before the final / are represented by folders.

Step 1: Login to your Azure DevOps account.

https://dev.azure.com/your_new_organization_name

Step 2: Navigate to Your Azure DevOps Organization => Your Azure DevOps Project => Project Settings => Repository => Select the repository => Policies, and enable “Case enforcement”.

How to enable case sensitivity for a repository in Azure Repos?

Now if you try to create a file/dir/branch/tag with same name but different case, you will get below errors.

  • The path ‘/some/path/somefile’ only differs from an existing file by case.
  • Name conflicts with refs/heads/somebranch
  • Name conflicts with refs/heads/sometag

Step 1: Login to your Azure DevOps account.

https://dev.azure.com/your_new_organization_name

Step 2: Navigate to Your Azure DevOps Organization => Your Azure DevOps Project => Project Settings => Repository => Select the repository => Policies, and enable “Reserved names”.

How to enable usage of reserved named for a repository in Azure Repos?

Now if you try to create a file or directory or path with reserved names, you will get an error “The push was rejected because COM9 starts with ‘COM9’, which is a reserved file or directory name.”

How to enable maximum path length for a repository in Azure Repos?

Now if you try to create a path with more than 10 characters long, you will get an error “The push was rejected because one or more commits contain path ‘/thisisalongpath/test.txt’, which exceeds the maximum path length of 10 characters.”

How to set maximum file size that can be pushed in Azure Repos?

Now if you try to push a file with more than 1 MB of size in your Azure repo, you will get an error “The object will increase this repository size by 4461218 bytes (the limit is 1048576 bytes)”.

How to make approval mandatory for pull requests in Azure Repos?

Step 1: Login to your Azure DevOps account.

https://dev.azure.com/your_new_organization_name

Step 2: Navigate to Your Azure DevOps Organization => Your Azure DevOps Project => Repos => Your Azure Repository => Branches => Your Azure Repository Branch Options => Branch Policies

How to make approval mandatory for pull requests in Azure Repos?

Enable “Require a minimum number of reviewers” and provide the minimum number of reviewers you want to add for approval of the pull request. In addition, you can also enable below options –

  • If Allow requestors to approve their own changes is selected, the creator of the pull request may vote on its approval. If not, they can still vote Approve on their pull request, but their vote won’t count toward the Minimum number of reviewers.
  • By default, anyone with push permissions on the source branch may both add commits and vote on the pull request’s approval. By enabling Prohibit the most recent pusher from approving their own changes, you can enforce segregation of duties – having the most recent push automatically makes the pusher’s vote not count.
  • If any reviewer rejects the changes, the pull request can’t finish unless you select Allow completion even if some reviewers vote to wait or reject.
  • You can reset code reviewer votes when new changes are pushed to the source branch. Select Reset code reviewer votes when there are new changes.

How to configure merge types for a repository in Azure Repos?

Azure Repos has multiple merge strategies, and by default, all of them are allowed. Select Limit merge types to pick which ones you’ll allow in your repo.

  • Basic merge (no fast-forward) – creates a merge commit in the target whose parents are the target and source branches.
  • Squash merge – creates a linear history with a single commit in the target branch with the changes from the source branch.
  • Rebase and fast-forward – creates a linear history by replaying source commits onto the target branch with no merge commit.
  • Rebase with merge commit – replays the source commits onto the target and still creates a merge commit.

Step 1: Login to your Azure DevOps account.

https://dev.azure.com/your_new_organization_name

Step 2: Navigate to Your Azure DevOps Organization => Your Azure DevOps Project => Repos => Your Azure Repository => Branches => Your Azure Repository Branch Options => Branch Policies => Enable “Limit merge types” and select the merge requests types as per your requirements.
