Draft Diff 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.

draft_commits	GET	Draft Diff Commit List Resource
draft_files	GET	Draft File Diff List Resource
self	GET	Draft Diff Resource

HTTP GET¶

Returns the information or contents on a particular diff.

The output varies by mimetype.

If application/json or application/xml is used, then the fields for the diff are returned, like with any other resource.

If text/x-patch is used, then the actual diff file itself is returned. This diff should be as it was when uploaded originally, with potentially some extra SCM-specific headers stripped. The contents will contain that of all per-file diffs that make up this diff.
