RepoEdit via API fails with "repo is not a mirror, can not change mirror interval"

[PulsarFX]

Description

When editing a repo with the GiteaAPI we get this error:

GiteaAPI.Client.ApiException
  HResult=0x80131500
  Message=Error calling RepoEdit: {"message":"repo is not a mirror, can not change mirror interval","url":"http://...:3000/api/swagger"}

  Source=GiteaAPI
  StackTrace:
   at GiteaAPI.Api.RepositoryApi.<RepoEditWithHttpInfoAsync>d__240.MoveNext()
   at GiteaAPI.Api.RepositoryApi.<RepoEditAsync>d__239.MoveNext()
   

when calling RepoEditAsync with some options and EditRepoOption { MirrorInterval=null } which should do nothing to the mirror interval, as stated in RepoEditAsync summary: "Edit a repository's properties. Only fields that are set will be changed"

This happens in 1.22-RC.1 and also 1.21.11 , but not in 1.21.1 (that's the versions we tested)

Gitea Version

1.22-RC.1

Can you reproduce the bug on the Gitea demo site?

Have you set EnablePrune? It seems that EnablePrune is also for mirror only.

If neither MirrorInterval nor EnablePrune is set, then I guess API won't report the error?

I have to dig some more. Hand crafted request via swagger Gui runs fine:

curl -X 'PATCH' \
  'http://localhost:3000/api/v1/repos/testdb/testdb' \
  -H 'accept: application/json' \
  -H 'authorization: Basic b.....z' \
  -H 'Content-Type: application/json' \
  -d '{
  "archived": false,
  "description": "repo description",
  "has_issues": false,
  "has_packages": true,
  "has_projects": false,
  "mirror_interval": null,
  "template": false
}'

Existing C# code, which is calling gitea via openApi generated c# client fails:

await _repositoryApi.RepoEditAsync(organizationName, organizationName, 
                 new EditRepoOption() { HasPullRequests = false });

This is the payload for this issue test:

[PulsarFX]

quick check: openApi did not generate different code for class EditRepoOption between 1.21.3 and 1.21.11:

        /// <summary>
        /// set to a string like &#x60;8h30m0s&#x60; to set the mirror interval time
        /// </summary>
        /// <value>set to a string like &#x60;8h30m0s&#x60; to set the mirror interval time</value>
        [DataMember(Name = "mirror_interval", EmitDefaultValue = false)]
        public string MirrorInterval { get; set; }

Executing method RepositoryApi RepoEditWithHttpInfoAsync didn't change neither.

Hmm yes, the problem is that EnablePrune = false makes the backend runs the "update mirror" logic ......

Maybe it could be fixed by fine-tuning the logic again.

[PulsarFX]

maybe make EnablePrune nullable, like public bool? EnablePrune {get; set;} ?
Both states are valid for calling the api. So, to not use it, a third state is required. In swagger, the property can simply be left out, but not in EditRepoOption as it is just of type bool.

[wxiaoguang]

Actually, the EnablePrune has the same definition as MirrorInterval. Ideally the SDKs should know that EnablePrune is optional and shouldn't send it to server, no idea why the SDK still sends it.

	// set to a string like `8h30m0s` to set the mirror interval time
	MirrorInterval *string `json:"mirror_interval,omitempty"`
	// enable prune - remove obsolete remote-tracking references when mirroring
	EnablePrune *bool `json:"enable_prune,omitempty"`

I think we can do this on Gitea side: " Simplify mirror repository API logic #30963 " and have simpler code.

1.22 nightly is ready, could you try it? https://dl.gitea.com/gitea/1.22/ or by docker "1.22-nightly"
