Recently we introduced the ability to load truncated AOFs, but
unfortuantely the support was broken since the server, after loading the
truncated AOF, continues appending to the file that is corrupted at the
end. The problem is fixed only in the next AOF rewrite.
This commit fixes the issue by truncating the AOF to the last valid
opcode, and aborting if it is not possible to truncate the file
correctly.
The code to check the number of voters was never updated to follow the new
Sentinel specification, so the number of voters was computed using only
the set of Sentinels that provided a vote.
This means that there is a changing majority on partitions, even if
usually the issue is not triggered because of the configured quorum
check (what was broken was the other implicit check that requires anyway
half of the known sentinels to agree in order to start a failover).
Because of the new ability to start with a truncated AOF, we need
to correctly release all the memory on EOF error. Otherwise there is a
small leak, that is not really a problem, but causes a false positive in
the tests that detect memory leaks.
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.
Previously, GETRANGE of a key containing nothing ("")
would allocate a large (size_t)-1 return value causing
crashes on 32bit builds when it tried to allocate the
4 GB return string.
32 bit builds don't have a big enough long to capture
the same range as a 64 bit build. If we use "long long"
we get proper size limits everywhere.
Also updates size of unsigned comparison to fit new size of `end`.
Fixes#1981
This allows to support datasets with more than 2 billion of keys
(possible in very large memory instances, this bug was actually
reported).
Closes issue #1814.
This just deletes old code that didn't get removed when
logic changed. We were setting offsets that never
got read anywhere.
Since clients are now just cloned, we don't need to track
per-client buffer offsets anywhere because they are all
the same from the original client.
This commit adds a size check after initial config
line parsing to make sure we have *at least* 8 arguments
per line.
Also, instead of asserting for cluster->myself, we just test
and error out normally (since the error does a hard exit anyway).
Closes#1597
For some Solaris flavours, the inet_aton in in resolv library.
Not linking this library will introduce link error.
Improves compatability with older Solaris and still
works on new Solaris.
Closes#1092
The funciton was also modified in order to be more standalone and
produce an output without trailing spaces, making the reuse simpler.
The global variable was renamed in cammel case as most other Redis
globals, except the main ones we refer too many times, like 'server'.
