Description:
This issue is an initial version for limited invalidation. It has not
been finished yet. I will send another code review when it's ready.
Here're what I did in this patch:
1. I added AuthenticationMode, InvalidateService,
DefaultInvalidateService and InvalidateHandler
2. I added AuthType, SecurityToken and invalidation string to
RemoteContentRequest. Those will be used for checking invalidation.
3. I added AuthenticationMode to SecurityToken
TODO items:
1. Currently entry point for invalidation is:
GET /api/rest/invalidate?invalidationKey=xxx
The final format should be:
POST /api/rest/invalidate
Content-Type application/json
{
invalidationKeys: {xxx}
}
How can I generate such a request with oauth signed?
2. There is a pitfall about DefaultInvalidationService.
PHP cache is different from Java. CacheStorageFile will cache http
request to hard disk. So DefaultInvalidationService::$marker should be
stored to hard disk too. I will fix it in next patch.
3. unittests
