The tags passed into Statistics() calls are not supposed to be modified.
The balanceWriter in subscribers tried to modify them triggering a panic
because they can be nil.
The vet checks for some files did not pass for go 1.7. As part of a
preliminary start to making go 1.7 work with this software, go vet
should pass.
Also updated the gogo/protobuf dependency which fixed the code generator
to work with go 1.7 too. Ran `go generate` on the entire repository to
ensure every file was up to date.
There were three different outputs that could be output with columns
that were rather strange depending on if there was a name and if there
were tags with the response.
Normalized output now has the dashes always under the column names and
no dashes anywhere else for consistency.
- Single commit, PR follows conventions laid out by @Gouthamve in #5822
* main.go: struct field CpuFile should be CPUFile
* influx_inspect: loop equivalent to `for key := range...`
* adds comments to exported fields and consts
* fixes typo in `CHANGELOG.md`: text for #4702 now matches number
It is now possible to use a mixed duration unit like `1h30m`. The
duration units can be in whatever order as long as they are connected to
each other.
There is a change to the scanner. A token such as `10x` will be scanned
as a duration literal, but will then fail to parse as an invalid
duration. This should not be a breaking change as there is no situation
where `10m10` was a valid order of tokens for the parser.
Fixes#3634.
Instead of having the parser set the defaults, the command will set the
defaults so that the constants for that are actually used. This way we
can also identify which things the user provided and which ones we are
filling with default values.
This allows the meta client to be able to make smarter decisions when
determining if the user requested a conflict or if the requested
capabilities match with what is currently available. If you just say
`CREATE DATABASE WITH NAME myrp`, the user doesn't really care what the
duration of the retention policy is and just wants to use the default.
Now, we can use that information to determine if an existing retention
policy would conflict with what the user requested rather than returning
an error if a default value ever gets changed since the meta client
command can communicate intent more easily.
This commit fixes the `MaxSelectSeriesN` limit which was broken by
the implementation of lazy iterators. The setting previously limited
the total number of series but the new implementation limits the
concurrent number of series being processed.
Updating the help formatting for all of the commands for consistency.
Removed tabs from the output in favor of using spaces so it is more
clear how the output is intended to look.
Truncate the time interval output of the monitor service to be on even
time intervals rather than on every minute based on the start time. This
normalizes the output from the monitor service.
Removing the data only build tag because it is no longer used. It was
previously used for building a data only node from the open source build
that could be used in clustering, but all of the RPC code was removed
since the separation was too much of a hindrance on development whenever
we found a bug.
Since the original purpose of this is now useless, there's no point in
having a confusing build tag around.
Previously, a non-admin could not call "use" in the influx cli since the
`SHOW DATABASES` command requires admin permissions to run. The correct
solution to this is likely to allow non-admins to call `SHOW DATABASES`,
but only see the databases they should be capable of seeing.
Since we don't have this kind of fine-grained authorization yet and
plans for it are still in the works, we do need someway to not
arbitrarily cripple non-admins attempting to use the cli program. This
is a temporary solution that will ignore any authorization errors from
`SHOW DATABASES` if authorization has been set. A warning message will
be printed and the database will be switched. This should be enough to
ensure that there is some warning that you may not have switched to a
valid database while not crippling non-admin users.
A temporary solution for #6397.
Normalize the output for the various help options so they all follow the
same format and display all relevant options.
Removing some of the unused config options from the configuration file
and updating the help documentation. Removing some remaining references
to clustering within the open source version.
Removes the old implementation of `dumptsm`. It was for an older version
of the tsm1 files that is no longer used and now just panics when used
on a tsm1 file. dumptsmdev has been renamed to `dumptsm`, but the old
`dumptsmdev` command still works for compatibility.
Updated `influx_inspect` to use the `FieldDimensions` method instead
(more reliable anyway). The `influx_tsm` program used its own vendored
copy of `FieldCodec` so it is not affected by this change. `FieldCodec`
was only used for the `b1` and `bz1` engines which were removed in 0.12,
but the code that created the field codec was never removed. This
limited the maximum number of fields to 255 even though that restriction
was removed with the `tsm1` engine.
Fixes#6869.
This adds support for using regex expressions in SHOW TAG VALUES when
selecting the key. Also supporting the `!=` operation for the
comparison. Now you can do any of the following:
SHOW TAG VALUES WITH KEY != "region"
SHOW TAG VALUES WITH KEY =~ /region/
SHOW TAG VALUES WITH KEY !~ /region/
It also adds a new SetLiteral AST node that will potentially be used in
the future to allow set operations for other comparisons in the future.
Fixes#4532.
The task manager now acts as its own statement executor so that a custom
statement executor can perform custom actions for KillQueryStatement and
ShowQueriesStatement.
Previously, the goroutine would block for 24 hours and would only check
every 24 hours if the server was closed. Since this never happened, the
goroutine would just be abruptly killed when the main process ended
(since nobody waited for this goroutine to end).
Updating the code to exit when the server is closed immediately and
switching the timer to a ticker instance that can be stopped.
This switch the backup shard call to use the shard Snapshot that
internally creates a snapshot by hardlinking all of the TSM and
tombstone files instead. This reduces the time that the FileStore
is locked and will allow for larger shards to be backup more easily.
If all points in a series are timestamped in the future, the SHOW
queries will not return anything from these series.
This commit changes the to time used when querying shards for the SHOW
queries to the maximum time, in order to ensure future points are
considered in the results for these queries.
Fixes#6599.
The default retention policy name is changed to "autogen" instead of
"default" since it ends up being ambiguous when we tell a user to check
the default retention policy, it is uncertain if we are referring to the
default retention policy (which can be changed) or the retention policy
with the name "default".
Now the automatically generated retention policy name is "autogen".
The default retention policy is now also configurable through the
configuration file so an administrator can customize what they think
should be the default.
Fixes#3733.
If you use a statement like this:
SELECT value FROM one..cpu, two..cpu
It will access both the `one` and `two` databases as if you had selected
the `cpu` measurement twice for both of them. Updated the `tsdb.Shard`
create iterator function to filter out any sources that do not apply to
that shard so this duplication doesn't happen.
Fixes#6701.
Casting syntax is done with the PostgreSQL syntax `field1::float` to
specify which type should be used when selecting a field. You can also
do `field1::field` or `tag1::tag` to specify that a field or tag should
be selected.
This makes it possible to select a tag when a field key and a tag key
conflict with each other in a measurement. It also means it's possible
to choose a field with a specific type if multiple shards disagree. If
no types are given, the same ordering for how a type is chosen is used
to determine which type to return.
The FieldDimensions method has been updated to return the data type for
the fields that get returned. The SeriesKeys function has also been
removed since it is no longer needed. SeriesKeys was originally used for
the fill iterator, but then expanded to be used by auxiliary iterators
for determining the channel iterator types. The fill iterator doesn't
need it anymore and the auxiliary types are better served by
FieldDimensions implementing that functionality, so SeriesKeys is no
longer needed.
Fixes#6519.
Accidentally used `FromToml()` when trying to read from a file path
rather than `FromTomlFile()` which will read the file and then call
`FromToml()`.
Fixes#6578.
This commit changes the `SeriesIterator` to process one measurement
at a time and uses a `floatFastDedupeIterator` to avoid point
encoding during deduplication.
An offset of `time(1m, now())` will anchor the offset to the current
time of the query. The default offset is `0s` which is the current
default anyway.
This fixes#2074 by making time zone offset support unnecessary. Time
comparisons can use timezones inside of the time clause and the offset
needed for non-hour timezone differences can be used as part of the
offset argument.
The time of the point will be returned with a selector when there is no
group by interval and when there is only one selector. Any other
conditions will return the start time of the interval.
Fixes#5890.
In order to follow REST a bit more carefully, all write operations
should go through a POST in the future. We still allow read operations
through either GET or POST (similar to the Graphite /render endpoint),
but write operations will trigger a returned warning as part of the JSON
response and will eventually return an error.
Also updates the Golang client libraries to always use POST instead of
GET.
Fixes#6290.
This also removes the dependency on `os/user` and uses the `HOME`
environment variable which is more common on Linux and Mac OS X for
customizing the history file location.
Removing this import also lets the `influx` binary be cross-compiled as
`os/user` relies on cgo.
There are two TSMIndex implementations, the directIndex and the
indirectIndex. Originally, we only had the directIndex and later
added the indirectIndex and NewTSMReaderWithOptions in order to
allow both indexes to be used in tests and code. This has created
a problem since we really only use the directIndex for writing and
always use the indirectIndex for reading.
This changes removes the NewTSMReaderWithOptions func so that it is
no longer possible to create a TSMReader with a directIndex. This
will allow a lot of the block reading code used by the directIndex
to be removed and simplify maintainence. It also gives better test
coverage of the code that is actually used by the TSM engine now.
