Because private fields would automatically add a bunch of fields to
the user's request (in order to do their own post-treatment), unlike
normal behavior `read([])` would be completed to `read(['privacy',
'user_id'])` and would fail to trigger the "select all the fields"
behavior of `BaseModel.read`.
Move the privacy management to a `_read` override instead. Also update
the code to be more linear and straightforward, without a bunch of
intermediate helper function.
This is also a small performance optimisation, although apparently
much more minor for 14 (best case of about 5%) than on 15.0 (where it
seemed to reach 30). The gain is mostly for private events being read
for non-participants: because the non-public fields get neutered
before computation (rather than after), fields are computed on a
neutered basis and thus largely do nothing. This is especially salient
with computations relying on relations (in this case
`attendee_status`), as from an empty starting point they essentially
do not do anything.
This leads to the effort (and cost) of private events being read by
non-participants to be about the same as the cost of public events,
whereas before the change there is a visible overhead. The signal is
quite noisy though.
NOTE: backported the addition of `privacy` to the public fields from
2f4a91c0ce as that is better
behavior and makes the tests more logical (and easier to forward
port probably)
