Repositories API

DETAILS: Tier: Free, Premium, Ultimate Offering: GitLab.com, GitLab Self-Managed, GitLab Dedicated

List repository tree

Iterating pages of results with a number (?page=2) deprecated in GitLab 14.3.

Get a list of repository files and directories in a project. This endpoint can be accessed without authentication if the repository is publicly accessible.

This command provides essentially the same features as the git ls-tree command. For more information, refer to the section Tree Objects in the Git internals documentation.

WARNING: This endpoint changed to keyset-based pagination in GitLab 15.0. Iterating pages of results with a number (?page=2) is unsupported.

GET /projects/:id/repository/tree

Supported attributes:

Attribute	Type	Required	Description
`id`	integer or string	yes	The ID or URL-encoded path of the project.
`page_token`	string	no	The tree record ID at which to fetch the next page. Used only with keyset pagination.
`pagination`	string	no	If `keyset`, use the keyset-based pagination method.
`path`	string	no	The path inside the repository. Used to get content of subdirectories.
`per_page`	integer	no	Number of results to show per page. If not specified, defaults to `20`. For more information, see Pagination.
`recursive`	boolean	no	Boolean value used to get a recursive tree. Default is `false`.
`ref`	string	no	The name of a repository branch or tag or, if not given, the default branch.

## Add changelog data to a changelog file

> - Commit range limits [introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/89032) in GitLab 15.1 [with a flag](../administration/feature_flags.md) named `changelog_commits_limitation`. Disabled by default.
> - [Enabled on GitLab.com and by default on self-managed](https://gitlab.com/gitlab-org/gitlab/-/issues/33893) in GitLab 15.3.
> - [Generally available](https://gitlab.com/gitlab-org/gitlab/-/issues/364101) in GitLab 17.3. Feature flag `changelog_commits_limitation` removed.

Generate changelog data based on commits in a repository.

Given a [semantic version](https://semver.org/) and a range
of commits, GitLab generates a changelog for all commits that use a particular
[Git trailer](https://git-scm.com/docs/git-interpret-trailers). GitLab adds
a new Markdown-formatted section to a changelog file in the Git repository of
the project. The output format can be customized.

For performance and security reasons, parsing the changelog configuration is limited to `2` seconds.
This limitation helps prevent potential DoS attacks from malformed changelog templates.
If the request times out, consider reducing the size of your `changelog_config.yml` file.

For user-facing documentation, see [Changelogs](../user/project/changelogs.md).

| `trailer` | string   | no | The Git trailer to use for including commits. Defaults to `Changelog`. Case-sensitive: `Example` does not match `example` or `eXaMpLE`. |

### Requirements for `from` attribute

If the `from` attribute is unspecified, GitLab uses the Git tag of the last
stable version that came before the version specified in the `version`
attribute. For GitLab to extract version numbers from tag names, Git tag names
must follow a specific format. By default, GitLab considers tags using these formats:

- `vX.Y.Z`
- `X.Y.Z`

Where `X.Y.Z` is a version that follows [semantic versioning](https://semver.org/).
For example, consider a project with the following tags:

- `v1.0.0-pre1`
- `v1.0.0`
- `v1.1.0`
- `v2.0.0`

If the `version` attribute is `2.1.0`, GitLab uses tag `v2.0.0`. And when the
version is `1.1.1`, or `1.2.0`, GitLab uses tag `v1.1.0`. The tag `v1.0.0-pre1` is
never used, because pre-release tags are ignored.

The `version` attribute can start with `v`. For example: `v1.0.0`.
The response is the same as for `version` value `1.0.0`. [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/437616) in GitLab 17.0.

If `from` is unspecified and no tag to use is found, the API produces an error.
To solve such an error, you must explicitly specify a value for the `from`
attribute.

### Migrating from a manually-managed changelog file to Git trailers

When you migrate from an existing manually-managed changelog file to one that uses Git trailers,
make sure that the changelog file matches [the expected format](../user/project/changelogs.md).
Otherwise, new changelog entries added by the API might be inserted in an unexpected position.
For example, if the version values in the manually-managed changelog file are specified as `vX.Y.Z`
instead of `X.Y.Z`, then new changelog entries added using Git trailers are appended to the end of
the changelog file.

[Issue 444183](https://gitlab.com/gitlab-org/gitlab/-/issues/444183) proposes customizing the version header format in changelog files.
However, until that issue has been completed, the expected version header format in changelog files is `X.Y.Z`.

### Examples

These examples use [cURL](https://curl.se/) to perform HTTP requests.
The example commands use these values:

- **Project ID**: 42
- **Location**: hosted on GitLab.com
- **Example API token**: `token`

This command generates a changelog for version `1.0.0`.

The commit range:

- Starts with the tag of the last release.
- Ends with the last commit on the target branch. The default target branch is
  the project's default branch.

If the last tag is `v0.9.0` and the default branch is `main`, the range of commits
included in this example is `v0.9.0..main`:

To generate the data on a different branch, specify the `branch` parameter. This
command generates data from the `foo` branch:

```json

## Generate changelog data

> - [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/172842) authentiation through [CI/CD job token](../ci/jobs/ci_job_token.md) in GitLab 17.7.

Generate changelog data based on commits in a repository, without committing
them to a changelog file.

Works exactly like `POST /projects/:id/repository/changelog`, except the changelog
data isn't committed to any changelog file.

```plaintext
GET /projects/:id/repository/blobs/:sha
```0

Supported attributes:

| Attribute | Type     | Required   | Description |
| :-------- | :------- | :--------- | :---------- |
| `version` | string   | yes | The version to generate the changelog for. The format must follow [semantic versioning](https://semver.org/). |
| `config_file` | string   | no | The path of changelog configuration file in the project's Git repository. Defaults to `.gitlab/changelog_config.yml`. |
| `date`    | datetime | no | The date and time of the release. Uses ISO 8601 format. Example: `2016-03-11T03:45:40Z`. Defaults to the current time. |
| `from`    | string   | no | The start of the range of commits (as a SHA) to use for generating the changelog. This commit itself isn't included in the list. |
| `to`      | string   | no | The end of the range of commits (as a SHA) to use for the changelog. This commit _is_ included in the list. Defaults to the HEAD of the default project branch. |
| `trailer` | string   | no | The Git trailer to use for including commits. Defaults to `Changelog`. |
