Draft Diff List Resource¶

Added in 2.0

Provides information on pending draft diffs for a review request.

This list will only ever contain a maximum of one diff in current versions. This is to preserve compatibility with the public Diff Resource.

POSTing to this resource will create or update a review request draft with the provided diff. This also mirrors the public diff resource.

HTTP GET¶

Returns the list of draft diffs on the review request.

Each diff has the target revision and list of per-file diffs associated with it.

Errors¶

100 - Does Not ExistHTTP 404 - Not Found	Object does not exist
101 - Permission DeniedHTTP 403 - Forbidden	You don’t have permission for this
103 - Not Logged InHTTP 401 - Unauthorized	You are not logged in

HTTP POST¶

Creates a new diff by parsing an uploaded diff file.

This will implicitly create the new Review Request draft, which can be updated separately and then published.

This accepts a unified diff file, validates it, and stores it along with the draft of a review request. The new diff will have a revision of 0.

A parent diff can be uploaded along with the main diff. A parent diff is a diff based on an existing commit in the repository, which will be applied before the main diff. The parent diff will not be included in the diff viewer. It’s useful when developing a change based on a branch that is not yet committed. In this case, a parent diff of the parent branch would be provided along with the diff of the new commit, and only the new commit will be shown.

It is expected that the client will send the data as part of a multipart/form-data mimetype. The main diff’s name and content would be stored in the path field. If a parent diff is provided, its name and content would be stored in the parent_diff_path field.

An example of this would be:

– SoMe BoUnDaRy
Content-Disposition: form-data; name=path; filename=”foo.diff”

<Unified Diff Content Here>
– SoMe BoUnDaRy –

Extra data can be stored on the diff for later lookup by passing extra_data.key_name=value. The key_name and value can be any valid strings. Passing a blank value will remove the key. The extra_data. prefix is required.

Request Parameters¶

pathUploaded File	Required The main diff to upload.
base_commit_idString	The ID/revision this change is built upon. If using a parent diff, then this is the base for that diff. This may not be provided for all diffs or repository types, depending on how the diff was uploaded. Added in 1.7.13
basedirString	The base directory that will prepended to all paths in the diff. This is needed for some types of repositories. The directory must be between the root of the repository and the top directory referenced in the diff paths.
parent_diff_pathUploaded File	The optional parent diff to upload.
