The list of the indexes in your account. The app uses it to know whether this phone's index exists, and to offer the indexes of your other phones when a new phone signs in.
01 · The call
POST https://opensolr.com/solr_manager/api/get_index_listA form with email and api_key.
When the app calls it:
- at setup, to find this phone's index or to ask Re-use one of these indexes from your Opensolr account?;
- at the start of a sync, only when photos_sync_info could not answer.
02 · The answer
A JSON list, one entry per index. The app reads index_name, and for photo indexes device_name, device_id, num_docs, last_index and created: the phone each index was made for, how many photos it holds and when it last synced, which is what the re-use question shows.
The rule that prevents stray indexes
The app creates an index only after this list was read successfully and did not contain it. A network error, a server error or a refused key never leads to a create.
