"Automatic ReviewDb only available in request scope" error while executing gApi.changes().id(myId).current().review(input);

[Sharath Gupta]

Hi

I am writing a plugin which needs the following requirement:

Plugin listens to particular event, on that event, create a new thread and from that new thread review a particular change using gApi.changes().id(myId).current().review(input); 

1)

I have a gApi instance in the plugin thread and when I try to pass gApi for the new thread, it receives null.

2)

I got the instance of RevisionApi in plugin thread as RevisionApi rApi = gApi.changes().id(myId).current(); and tried to pass rApi to the new thread. rApi was not null but got the following error when I tried to review using this command rApi.review(input);

com.google.inject.ProvisionException: Unable to provision, see the following errors:

1) Automatic ReviewDb only available in request scope

  at com.google.gerrit.server.util.ThreadLocalRequestContext$1.provideReviewDb(ThreadLocalRequestContext.java:70) (via modules: com.google.gerrit.server.config.GerritGlobalModule -> com.google.gerrit.server.util.ThreadLocalRequestContext$1)

  while locating com.google.gerrit.reviewdb.server.ReviewDb

1 error

at com.google.gerrit.server.change.PostReview.apply(PostReview.java:144)

at com.google.gerrit.server.api.changes.RevisionApiImpl.review(RevisionApiImpl.java:168)

at 

I am able to give the review from the plugin thread itself successfully but not from a new thread. 

PLease let me know how do I resolve this.

Thanks

This code must be executed in a request context.

If you start a background thread you must create this context:

Get OneOffRequestContext injected and then do

try (ManualRequestContext ctx = oneOffRequestContext.open()) {

      // call gApi

} 

PLease let me know how do I resolve this.

Thanks
