Find hash of a commit based on the name of its tag about azure-devops-cli-extension HOT 4 CLOSED

Going forward you can file your vsts-python-api issues directly in the vsts-python-api repo:
https://github.com/Microsoft/vsts-python-api/issues

I have forwarded your question to the git api team, and will get back to you.

On a side note, we have a new documentation site for the VSTS APIs with examples. Our python-sdk-api is just a wrapper for the REST apis, so you may find useful information here:

from azure-devops-cli-extension.

You can get all the tags from the /refs/tags endpoints. For example, tag1 below is annotated and tag2 is a lightweight:

{
value: [
{
name: "refs/tags/tag1",
objectId: "b0fa354e399adc227fe013e3a9e1b4947659beee",
},
{
name: "refs/tags/tag2",
objectId: "6d9ae2bf6883412bab2d389a3b5e1447003944eb",
}
],
count: 2
}

In the tag2 case, the objectId is the commit as it is a lightweight tag. In the tag1 case, if we want the commitId we need to crack the annotated tag, which you can do with the annotated tag endpoint (https://docs.microsoft.com/en-us/rest/api/vsts/git/Annotated%20Tags/Get). In my example, if I go to /annotatedtags/b0fa354e399adc227fe013e3a9e1b4947659beee off the repository REST API, I then get the response:

{
name: "refs/tags/tag1",
objectId: "b0fa354e399adc227fe013e3a9e1b4947659beee",
taggedObject: {
objectId: "6d9ae2bf6883412bab2d389a3b5e1447003944eb",
objectType: "commit"
},
message: "hello",
}

In this result we see that the annotated tag b0fa354e399adc227fe013e3a9e1b4947659beee points to the object 6d9ae2bf6883412bab2d389a3b5e1447003944eb which is a commit. Since annottated tags can point to annotated tags, you may have to follow the chain until you get to the taggedObject being of objectType commit.

@WilAtMSFT @tedchamb thanks for the answer.
It would have been handy to not need to fire another request to distinguish between simple and annotated tags, but it's not an additional request that will make a big difference.
