This commit deletes most of the code to service reads from influxdb
and pulls it in from platform instead.
Of note, the models.Tag and models.Tags types are now aliases to the
platform models.Tag and models.Tags types. Additionally, many types
in the tsdb package relating to cursors are also aliases to the same
types in the platform cursors package.
This updates the platform and flux repos to the current master in the
Gopkg.lock.
* the protocol service definition, ReadRequest and ReadResponse is
reused across projects, rather than requiring redefinition.
* the ReadRequest protocol buffer definition removes the concept of a
database and retention policy, replacing it with a field named
ReadSource of type google.protobuf.Any. OSS requests will use the
ReadSource message structure defined in local to this package, which
defines fields to represent a Database and RetentionPolicy. Other
implementations can provide their own data structure allowing the
remainder of the ReadRequest to be reused.
* The RPC service and Store are expected to be redefined to handle their
specific requirements for resolving a ReadSource
* ResultSet and GroupResultSet are interfaces representing non-grouping
and grouping read behavior respectively. Calling NewResultSet or
NewGroupResultSet will construct instances of these types
* The ResponseWriter type is exported to deal with serialization of
the ResultSet and GroupResultSet types
* Update Prometheus remote write to use metric name as measurement name and value as the field name.
* Update Prometheus remote read to use the storage.Read method to bypass the InfluxQL query engine.
This commit adds `debug-pprof-enabled` which will start the default
`net/http/pprof` endpoint and bind against `localhost:6060`. This
will help to debug startup performance issues.
Updated flags, help text, removed documentation for deprecated legacy options. Updated documentation to describe the syntax and options for the newer -portable format. Legacy support remains, but is only referenced in the online documentation.
This code has been duplicated to other projects and its implementations
have grown out of sync. Now the code can live as a package-level
function rather than a method coupled with particular structs.
Remove the `Query` prefix from some structs and interfaces. They were
there so when the query engine was in the same package as influxql,
these would be differentiated. Now that the package name is query, the
extra prefix seems redundant.
For any systems that want to read the log file in the specific format,
the logo being printed on restart may not be good for those parsers
since the log parser would have to be aware of the logos existance or
capable of just ignoring lines it couldn't parse.
This gives an option to disable the printed logo if required.
Like other logging options, this will fail if the configuration file
itself is invalid.
* Live Restore + Enterprise data format compatability
* Extended ImportData to import all DB's if no db name given
* Added a new enterprise data test, and backup command now prints the backup file paths at conclusion
* Added whole-system backup test
* Update to use protobuf in all enterprise data cases
* Update to test to do cross-testing with enterprise version
* incremental enterprise backup format support
The previous sha was taken from a revision on a devel branch that I
thought would continue staying in the tree after it was merged. That
revision was rebased away and the API was changed for the logger.
This updates the usage of the logger and adds a simple package for
constructing the base logger.
The 1.0 version of zap changed the format of the default console logger
so this change moves over to this new logger instead of attempting to
retain backwards compatibility with the old format.
Windows computers may produce a utf16 file from the command line that
contains a byte-order-mark. Along with handling the utf8
byte-order-mark, this also handles the utf16 for better Windows
compatibility.
This change provides a clear separation between the query engine
mechanics and the query language so that the language can be parsed and
dealt with separate from the query engine itself.
The Points channel is nil until after the subscriber service is opened.
If it is append before it's opened, the PointsWriter holds onto the
old reference.
* off by default, enabled by `query-stats-enabled`
* writes to cq_query measurement of configured monitor database
* see CHANGELOG for schema of individual points
They rebased a revision we were previously relying upon that allowed us
to use the vanity name so we are reverting back to an older version with
the old import path.
URL=http://localhost:8086 go test -parallel 1 ./cmd/influxd/run
will run the tests over HTTP against localhost:8086. They currently
need to be run serially since they all write to the same DB.
This commit introduces a new interface type, influxql.Authorizer, that
is passed as part of a statement's execution context and determines
whether the context is permitted to access a given database. In the
future, the Authorizer interface may be expanded to other resources
besides databases. In this commit, the Authorizer interface is
specifically used to determine which databases are returned when
executing SHOW DATABASES.
When HTTP authentication is enabled, the existing meta.UserInfo struct
implements Authorizer, meaning admin users can SHOW every database, and
non-admin users can SHOW only databases for which they have read and/or
write permission.
When HTTP authentication is disabled, all databases are visible through
SHOW DATABASES.
This addresses a long-standing issue where Chronograf or Grafana would
be unable to list databases if the logged-in user did not have admin
privileges.
Fixes#4785.
The following types of queries will panic:
SELECT mean, host FROM (SELECT mean(value) FROM cpu GROUP BY host)
SELECT top(sum, host, 3) FROM (SELECT sum(value) FROM cpu GROUP BY host)
These queries _should_ work, but due to a current limitation with
aggregate functions, the aggregate functions won't return any auxiliary
fields. So even if a tag is not an auxiliary field, it is treated that
way by the query engine and this query will fail.
Fixing this properly will take a longer period of time. This fix just
prevents the panic from killing the server while we fix this for real.
The order of series keys is in ascending alphabetical order, not
descending alphabetical order, when it is ordered by descending time.
This fixes the ordering so points are returned in descending order. The
emitter also had the conditions for choosing which iterator to use in
the wrong direction (which only affects aggregates with `FILL(none)`).
When using `non_negative_derivative()` and `last()` in a math aggregate
with each other, the math would not be matched with each other because
one of those aggregates would emit one fewer point than the others. The
math iterators have been modified so they now track the name and tags of
a point and match based on those.
This isn't necessarily ideal and may come to bite us in the future. We
don't necessarily have a defined structure for all iterators so it can
be difficult to know which of two points is supposed to come first in
the ordering. This uses the common ordering that usually makes sense,
but the query engine is getting complicated enough where I am not 100%
certain that this is correct in all circumstances.
Fixes#7906
In an attempt to reduce the overhead of using regex for exact matches,
the query parser will replace `=~ /^thing$/` with `== 'thing'`, but the
conditions being checked would ignore if any flags were set on the
expression, so `=~ /(?i)^THING$/` was replaced with `== 'THING'`, which
will fail unless the case was already exact. This change ensures that no
flags have been changed from those defaulted by the parser.

With the new shard mapper implementation, regexes were just ignored so
it attempted to look up the field type inside of a measurement with no
name (which cannot possibly exist) so it would think the field didn't
exist and map it as the unknown type.
