Add API Endpoint for Branch Creation #11607

tle-huu · 2020-05-24T16:59:28Z

This commit introduces an API endpoint for branch creation.
The added route is POST /repos/{owner}/{repo}/branches.

A JSON with the name of the new branch and the name of the "old" branch is required as parameters.

Thanks for PR :) It looks like you have modified the vendors/modules.txt file, this is likely due to working with an older version of Go. Could you revert your changes from that specific file?

since you dont use RepoRefByType you have to:

check if ctx.Repo.Repository.IsEmpty { first

and since repo_module.CreateNewBranch return no specific error if the OldBranch not exist,
at the moment it will cause a 500 errror
Either:

create a custom error and extend the function CreateNewBranch here:

gitea/modules/repository/branch.go

Lines 73 to 75 in 3aedc79

    
           if !git.IsBranchExist(repo.RepoPath(), oldBranchName) { 
        
           	return fmt.Errorf("OldBranch: %s does not exist. Cannot create new branch from this", oldBranchName) 
        
           }

a 404 responce is expected (has to be added to the swagger docs too)

Or:

check via !ctx.Repo.GitRepo.IsBranchExist(opt.OldBranchName) bevore this function is called
a 404 responce is expected (has to be added to the swagger docs too)

After this Only some Tests are missing :)

and a format question why do you created a second function (CreateRepoBranch) if you can just put the code into CreateBranch.

It would make sence if you like to re-use CreateRepoBranch but it is only used once

6543 · 2020-05-28T14:02:08Z

@tle-huu thanks for the pull, after the points above are resolved I think its good to go ;)

6543 · 2020-05-28T15:26:39Z

OK, one thing left Tests

tle-huu · 2020-05-28T16:43:55Z

OK, one thing left Tests

I have trouble running the tests locally, getting an internal error related to pushing / pre-receive hooks (when I run make test-pgsql):

CreateRepoBranch: PushRejected Error: exit status 1: remote: Gitea: Internal Server Error
        	remote: Unable to contact gitea: Post "http://localhost:3002/api/internal/hook/pre-receive/user2/repo1": dial tcp [::1]:3002: connect: connection refused

EDIT: Ok looks like it is not just locally..

6543 · 2020-05-28T18:37:43Z

the test itself looks good, so there is an issue with the CreateBranch implementation

tle-huu · 2020-05-28T20:05:03Z

Looks like it comes from an internal pre-receive hook (when I overwrite the hook in the gitea-repositories-meta repos it works), triggered because CreateNewBranch creates the new branch and then push it.

Zeripaths Idear of creating a temporary repo sound a good solution for this ...

Have you checked every call to CreateNewBranch and made sure they handle your new error correctly?

The other place where CreateNewBranch is used is in routers/repo/branch.go CreateBranch function and uses the ctx.Repo.BranchName as the "OldBranchName".

It does not "models.isErr" it but treats it as a ServerErr. Should we add a check there as well ? If so, should we do it in this PR or in another CL ?

Sorry, I accidentally "merged" master into this branch.

I rebased on master (but this is equivalent to 5df39561490e79cb3237d541cf906c09eab8cfed)

6543 · 2020-05-29T11:24:20Z

merging master int this (or hit the "update" button) is the normal way to let pulls be up-to-date
@tle-huu so dont worry
