This fixes several issues related to the bind address and hostname:
* Allows bind addresses where a hostname or IP is not specified to
work correct and bind to all interfaces by default.
* Fixes the top-level "hostname" config option to allow overridding
all bind address hostnames. This allows a node to advertise a different
hostname than what is defined in the bind address setting.
* Adds the -hostname command-line option back to allow specifing
both -join and -hostname as command-line flags.
* Enforces a configuration precedence and overriding ability defined
as config file is overridden by env vars which are overriden by command-line
flags.
Fixes#5670#5671
The name of the column will be every measurement located inside of the
math expression in the order they are encountered in within the
expression.
Also handle `*influxql.ParenExpr` in the function
`(*influxql.Field).Name()`
Fixes#5730.
Previously, meta.Client would drop the default retention policy when
trying to create a database with a retention policy. The RPC has now
been modified to include the desired retention policy in the
CreateDatabase command and have it use that retention policy information
instead of the default configuration when provided.
This also lowers the number of RPC calls for
CreateDatabaseWithRetentionPolicy to only a single RPC call instead of
two.
Protections have also been included so creating a retention policy with
different parameters will return an error similar to if you tried to
modify the retention policy separately.
Fixes#5696.
A case (#5606) was found where a lot of data unexpectedly disappeared from a database
following a TSM conversion.
The proximate cause was an inconsistency between the root Bolt DB bucket list
and the meta data in the "series" bucket of the same shard. There were apparently valid
series in Bolt DB buckets that were no longer referenced by the meta data
in the "series" bucket - so-called orphaned series; since the conversion
process only iterated across the series found in the meta data, the conversion process
caused the orphaned series to be removed from the converted shards. This resulted in the
unexpected removal of data from the TSM shards that had previously been accessible
(despite the meta data inconsistency) in the b1 shards.
The root cause of the meta data inconsistency in the case above was a failure, in versions prior
to v0.9.3 (actually 3348dab) to update the "series" bucket with series that had been created in
previous shards during the life of the same influxd process instance.
This fix is required to avoid data loss during TSM conversions for shards that were created with
versions of influx that did not include 3348dab (e.g. prior to v0.9.3).

This removes the MetaServers property from node.json to eliminate one
of the four places those addresses are stored on disk. We always use
the values that come through the config (via file, env var or -join arg).
top() and bottom() point ordering was incorrect and using an inefficient
method of sorting. It has now been updated to use a heap and ordering is
being done by value first and time second (with earlier times always
taking priority).
Removed unit tests that test using `time` inside of the query to get the
real time instead of the interval time and only allowing the default
behavior. We will have another mechanism to get the real time during an
interval, but the current method is deprecated.
The top() and bottom() methods now have integer support.
It had the time values for the selectors being returned equal the actual
points time. We have decided to have the time always be the interval
time and adding another feature later that can return the selected
point's time in the future.
