This change requires Erlang/OTP-21.0 or higher.
The commit also deprecates the following options:
- log_rotate_date
- log_rate_limit
Furthermore, these options have no effect. The logger now fully
relies on log_rotate_size, that cannot be 0 anymore.
The loglevel option now accepts levels in literal formats.
Those are: none, emergency, alert, critical, error, warning, notice, info, debug.
Old integer values (0-5) are still supported and automatically converted
into literal format.
Reasons:
- Riak DB development is almost halted after Basho
- riak-erlang-client is abandoned and doesn't work
correctly with OTP22
- Riak is slow in comparison to other databases
- Missing key ordering makes it impossible to implement range
queries efficiently (e.g. MAM queries)
This option was introduced to fulfill requirement of RFC3920 10.3,
but in practice it was very inconvenient and many admins were
forced to change its value to 's2s' (i.e. to behaviour that
violates the RFC). Also, it seems like in RFC6120 this requirement
no longer presents.
Those admins who used this option to block s2s with their subdomains
can use 's2s_access' option for the same purpose.
Option 'captcha_host' is now deprecated in favor of 'captcha_url'.
However, it's not replaced automatically at startup, i.e. both options
are supported with 'captcha_url' being the preferred one.
