same here, as long as you include storage and content, you need to depend on it

[Łukasz Anforowicz, 2015/06/26 22:37:23]

Makes sense for both storage and content.  I've made the change.

In the long-term we probably want to get rid of both dependencies.

content/browser/power_save_blocker:
- Weaning off power_save_blocker would ideally be done by
  componentizing power_save_blocker, but this is difficult
  (mostly because of current dependencies of
   content/browser/power_save_blocker_android.cc)
- So for now, we hoped to keep the include of power_save_blocker.h
  in components/drive, but when including components/drive outside
  of the browser binary we would provide a no-op implementation
  of PowerSaveBlocker::Create ("outside of the browser binary"
  = i.e. in the somewhat experimental Dokan-over-Drive4CrOS binary
  that is not related to Chrome in any way)
- I am not sure anymore that our idea is okay.  OTOH, this shouldn't
  block componentization of Drive4CrOS, which should be fine after
  taking the change suggestion from your feedback.
- One way out would to be provide an abstraction specific to
  components/drive (instead of PowerSaveBlocker).  This can
  be generic (i.e. callbacks when uploads start and end) or
  very similar to PowerSaveBlocker.
At any rate, I have to think more about it... :-/

storage/browser/fileapi/file_stream_reader.h:
- AFAIR hashimoto was saying that this can be moved out
  of components/drive.
