This has been done by exposing the anetSockName() function anet.c
to be used when the sentinel is publishing its existence to the masters.
This implementation is very unintelligent as it will likely break if used
with IPv6 as the nested colons will break any parsing of the PUBLISH string
by the master.
Replace inet_ntoa(3) calls with the more future proof inet_ntop(3)
function which is capable of handling additional address families.
API Change: anetTcpAccept() & anetPeerToString() additional argument
additional argument required to specify the length of the character
buffer the IP address is written to in order to comply with
inet_ntop(3) function semantics.
Change anetResolve() function to use getaddrinfo(3) to resolve hostnames.
Resolved hostnames are limited to those reachable by the AF_INET address
family.
API Change: anetResolve requires additional argument.
additional argument required to specify the length of the character
buffer the IP address is written to in order to comply with
inet_ntop(3) function semantics. inet_ntop(3) replaces inet_ntoa(3)
as it has been designed to be compatible with more address families.
Bind() can't be called multiple times against the same socket, multiple
sockets are required to bind multiple interfaces, silly me.
This reverts commit bd234d62bbfe9feb735fd6d1cdb8f5ce811f54b4.
Further details from @antirez:
It was reported by @StopForumSpam on Twitter that the Redis replication
link was strangely using multiple TCP packets for multiple commands.
This wastes a lot of bandwidth and is due to the TCP_NODELAY option we
enable on the socket after accepting a new connection.
However the master -> slave channel is a one-way channel since Redis
replication is asynchronous, so there is no point in trying to reduce
the latency, we should aim to reduce the bandwidth. For this reason this
commit introduces the ability to disable the nagle algorithm on the
socket after a successful SYNC.
This feature is off by default because the delay can be up to 40
milliseconds with normally configured Linux kernels.
Added a configuration directive to allow a user to specify the
permissions to be granted to the Unix socket file. I followed
the format Pieter and Salvatore discusses in issue #85 (
https://github.com/antirez/redis/issues/85).
networking related stuff moved into networking.c
moved more code
more work on layout of source code
SDS instantaneuos memory saving. By Pieter and Salvatore at VMware ;)
cleanly compiling again after the first split, now splitting it in more C files
moving more things around... work in progress
split replication code
splitting more
Sets split
Hash split
replication split
even more splitting
more splitting
minor change
