I've renamed maxmemoryToString to evictPolicyToString since that is
more accurate (and easier to mentally connect with the correct data), as
well as updated the function to user server.maxmemory_policy rather than
server.maxmemory. Now with a default config it is actually returning
the correct policy rather than volatile-lru.
An exposed Redis instance on the internet can be cause of serious
issues. Since Redis, by default, binds to all the interfaces, it is easy
to forget an instance without any protection layer, for error.
Protected mode try to address this feature in a soft way, providing a
layer of protection, but giving clues to Redis users about why the
server is not accepting connections.
When protected mode is enabeld (the default), and if there are no
minumum hints about the fact the server is properly configured (no
"bind" directive is used in order to restrict the server to certain
interfaces, nor a password is set), clients connecting from external
intefaces are refused with an error explaining what to do in order to
fix the issue.
Clients connecting from the IPv4 and IPv6 lookback interfaces are still
accepted normally, similarly Unix domain socket connections are not
restricted in any way.
Not perfect since The Solution IMHO is to have a DSL with a table of
configuration functions with type, limits, and aux functions to handle
the odd ones. However this hacky macro solution is already better and
forces to put limits in the range of numerical fields.
More field types to be refactored in the next commits hopefully.
Adds configuration option 'supervised [no | upstart | systemd | auto]'
Also removed 'bzero' from the previous implementation because it's 2015.
(We could actually statically initialize those structs, but clang
throws an invalid warning when we try, so it looks bad even though it
isn't bad.)
Fixes#2264
This removes:
- list-max-ziplist-entries
- list-max-ziplist-value
This adds:
- list-max-ziplist-size
- list-compress-depth
Also updates config file with new sections and updates
tests to use quicklist settings instead of old list settings.
The original implementation was modified in order to allow to
selectively announce a different IP or port, and to rewrite the two
options in the config file after a rewrite.
