This is surely something simple I'm overlooking. In the Azure DevOps web interface (not integrated as part of an IDE), I see how to compare any commit to its parent, but I can't figure out how to compare it to an arbitrary commit.

这肯定是我忽略的一件简单的事情。在Azure DevOps web界面（未作为IDE的一部分集成）中，我看到了如何将任何提交与其父级进行比较，但我不知道如何将其与任意提交进行比较。

ie, I'm looking for the equivalent of GitHub's compare/hash1..hash2 functionality.

即，我正在寻找相当于GitHub的compare/hash1..hash2功能。

The appeal is that the web UI is a view/tool common to everyone, and presumably I could get a link to the specific diff I'm interested in and share it with colleagues.

吸引人的是，web UI是每个人都通用的视图/工具，据推测，我可以获得我感兴趣的特定差异的链接，并与同事共享。

The web UI suggests it might be possible because when viewing the changes for a particular commit it has text Diff to Parent 1 - <my commit hash> but I haven't figured out how to change Parent 1.

web UI表明这可能是可能的，因为在查看特定提交的更改时，它有文本Diff to Parent 1-＜my commit hash＞，但我还没有弄清楚如何更改Parent 1。

If you go to the list of branches for a repository, you can click on ... (More Actions) on one of the branches and choose Compare branches

如果转到存储库的分支列表，可以单击。。。（更多操作），然后选择“比较分支”

This will take you to a URL in the form:
https://dev.azure.com/{organisation}/{project}/_git/{repository}/branches?baseVersion=GB{baseBranch}&targetVersion=GB{targetBranch}&_a=files

这会将您带到以下格式的URL：https://dev.azure.com/{organization}/{project}/_git/{repository}/分支机构？baseVersion=GB｛baseBranch｝targetVersion=GB{targetBranch}_a=文件

You can then change the baseVersion and targetVersion parameters in the query string. These can take the following forms, and can be mixed and matched:

然后，您可以更改查询字符串中的baseVersion和targetVersion参数。这些可以采取以下形式，并且可以混合和匹配：

• GB{branchName}


• GC{commitHash}


• GT{tagName}

Just in case that link gets broken, clicking "View Merge Changes" on a pull request takes you to the same page but with a slightly different URL https://dev.azure.com/{organisation}/{project}/_git/{repository}/branchCompare?baseVersion=GC{baseCommit}&targetVersion=GC{targetCommit}&_a=files

为了防止链接断开，在拉取请求上单击“查看合并更改”会将您带到同一页面，但URL略有不同https://dev.azure.com/｛organization｝/｛project｝/_git/｛repository｝/branchCompare？baseVersion=GC｛baseCommit｝targetVersion=GC{targetCommit｝_a=文件

I'm not sure if there's a nicer way of comparing commits from the UI, as it only shows branches and tags, but if you do it this way you don't have to temporarily tag commits or create temporary branches just to get a diff that shows all of the changed files.

我不确定是否有更好的方法来比较来自UI的提交，因为它只显示分支和标记，但如果你这样做，你不必临时标记提交或创建临时分支，只需获得一个显示所有更改文件的diff。

If you want to compare two arbitrary commits for one file, navigate to the file in the repo, select the compare tab, and apply the appropriate commit range.

如果要比较一个文件的两个任意提交，请导航到repo中的文件，选择“比较”选项卡，然后应用适当的提交范围。

If you want to compare two arbitrary commits for all files , you can create tags at commits , then compare them. This will give you a list of commits between them and allow you to show the diffs.

如果要比较所有文件的两个任意提交，可以在提交时创建标记，然后进行比较。这将为您提供它们之间的提交列表，并允许您显示差异。

For details, you can refer to this case.

有关详细信息，您可以参考本案例。

The Devops UI does now allow a comparison of the commits between branches as well as files. The URL is very similar to the one detailed in George Heylar's answer, you just change the end of the URL from 'files' to 'commits':

Devops UI现在允许比较分支和文件之间的提交。URL与George Heylar的回答中详细描述的非常相似，您只需将URL的末尾从“files”更改为“commits”：

https://dev.azure.com/{organisation}/{project}/_git/{repository}/branches?baseVersion=GB{baseBranch}&targetVersion=GB{targetBranch}&_a=commits

https://dev.azure.com/{organization}/{project}/_git/{repository}/分支机构？baseVersion=GB｛baseBranch｝targetVersion=GB{targetBranch}_a=提交

The short way to do that via the UI if 'Compare Branches' is not disabled

1. Open the Branch list for your project:

2. Click the vertical ellipsis button against the first branch you want to compare:

3. Select 'Compare branches' to open the screen below. If the 'Compare branches' option is disabled see the longer approach below.

4. Select the branch to compare to in the second combo and then you will see a list of the commit differences between the two branches:

5. If you want to see the file differences just choose the 'Files' option in the not terribly obvious tab control:

The long way to achieve that via the UI if 'Compare Branches' is disabled

1. Open the Branch list for your project:

2. Click the vertical ellipsis button against the first branch you want to compare:

3. Select 'Set as default branch'

   
   



4. Repeat the same process for the second branch you want to compare to:

   
   

5. This time select Select 'Set as compare branch'

   
   



6. Finally open the ellipsis menu again for the branch you set as the default branch (i.e. the one you picked in step 3 above)

   
   

7. Select the 'Compare branches' menu item and that will open the 'Branch Compare' page:

The "Diff to Parent 1" feature is described in "Commit details / What are the changes included in the commit?"

“提交详细信息/提交中包含哪些更改？”中介绍了“与父级1的差异”功能

Diff to parent - Click on Diff on parent1 in the Source Explorer pane to view the difference between the current commit and its parent commit.

One can see what Parent1 references in the diff view itself:

可以在diff视图中看到Parent1引用了什么：

But I don't see any web URL which could help reference that diff. Hence my initial Azure DevOps Git API that I proposed before.

但我没有看到任何web URL可以帮助引用这种差异。因此，我之前提出了我最初的Azure DevOps Git API。

If you would like to compare two commits of a branch...

如果您想比较一个分支的两次提交。。。

1. Go To branches.


2. Create a new branch from branch where you want to do comparison.


3. Create branch with the specific commit.
   enter image description here


4. Compare newly created branch with original branch.
