It's hard to pick a good approach here. A few arguments:
1) There are many exposed instances on the internet.
2) Changing the default when "bind" is not given is very dangerous,
after an upgrade the server changes a fundamental behavior.
3) Usually Redis, when used in a proper way, will be protected *and*
accessed often from other computers, so this new default is likely
not what most people want.
4) However if users end with this default, they are using the example
redis.conf: likely they are reading what is inside, and they'll see
the warning.
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.
- Remove trailing newlines from redis.conf
- Fix comment misspelling
- Clarifies zipEncodeLength usage and a C API mention (#1243, #1242)
- Fix cluster typos (inspired by @papanikge #1507)
- Fix rewite -> rewrite in a few places (inspired by #682)
Closes#1243, #1242, #1507
According to unix manuals, "Connecting to the socket object requires
read/write permission." -- mode 755 is useless for anybody
other than the owner.
Fixes#1696
Because of output buffer limits Redis internals had this idea of type of
clients: normal, pubsub, slave. It is possible to set different output
buffer limits for the three kinds of clients.
However all the macros and API were named after output buffer limit
classes, while the idea of a client type is a generic one that can be
reused.
This commit does two things:
1) Rename the API and defines with more general names.
2) Change the class of clients executing the MONITOR command from "slave"
to "normal".
"2" is a good idea because you want to have very special settings for
slaves, that are not a good idea for MONITOR clients that are instead
normal clients even if they are conceptually slave-alike (since it is a
push protocol).
The backward-compatibility breakage resulting from "2" is considered to
be minimal to care, since MONITOR is a debugging command, and because
anyway this change is not going to break the format or the behavior, but
just when a connection is closed on big output buffer issues.
This is safer as by default maxmemory should just set a memory limit
without any key to be deleted, unless the policy is set to something
more relaxed.
In high RPS environments, the default listen backlog is not sufficient, so
giving users the power to configure it is the right approach, especially
since it requires only minor modifications to the code.
IPv6 support is not going to use IPv6 specific options, just it will be
possible to specify all the ipv4 / ipv6 addresses of the interfaces to
bind, otherwise connections will be accepted from all the interfaces in
both IPv4 and IPv6 addresses.
This reverts commit 93570e179e.
This feature allows the user to specify the minimum number of
connected replicas having a lag less or equal than the specified
amount of seconds for writes to be accepted.
Also the logfile option was modified to always have an explicit value
and to log to stdout when an empty string is used as log file.
Previously there was special handling of the string "stdout" that set
the logfile to NULL, this always required some special handling.
