研究方向

從 v3.apps 迭代以及報告中顯示的 app.space() 和 space.organization() 呼叫開始,然後追蹤 InvalidStatusCode 回應的處理方式。完成的標準是:對某個 app 或 space 的 NOT_FOUND 可以略過,同時長時間執行的遍歷繼續進行,並且為其餘資源定義行為。

描述

Hi - We are using cf-python-client as part of a task which downloads each app-blob in turn. As we have tens of thousands of containers, this job takes 8-10 hours to complete.

The job is theoretically quite straightforward...

for app in cfClient.v3.apps:
    space_name=app.space()['name']
    org_name=app.space().organization()['name']
    ...

More often than not, during the running of this task, we'll encounter an error along the lines of...

cloudfoundry_client.errors.InvalidStatusCode: NOT_FOUND = {"errors": [{"detail": "Space not found", "title": "CF-ResourceNotFound", "code": 10010}]}

or

cloudfoundry_client.errors.InvalidStatusCode: NOT_FOUND = {"errors": [{"detail": "App not found", "title": "CF-ResourceNotFound", "code": 10010}]} 

Given the number of orgs/spaces/apps we have in service, it is not too surprising that an app or space which was present at the start of the task is no longer around 6-8 hours later.

When we encounter an error like this we have no options but to restart the 8-10 hour task from the beginning again and hope that it manages to make it through without an error.

I was just wondering if there are any options to allow for more graceful continuation when objects are no longer found? This doesn't seem to be something that I can handle with a try: except: - Are there any options to make errors like this non-fatal?

Cheers!!
