We were seing segfaults in Roaring bitmaps sometimes, under very
high load with networked drives. This may reduce risk of segfault by
forcing marshalling to copy the data.
refactor(influxdb): Refactor trace code for clarity and reliability
* Make startProfile a method of Server. startProfile() is only used one
place. We bother to copy the Server.CPUProfile and Server.MemProfile
values out of our Server struct into it's parameters. It makes more
sense to make startProfile() a method of Server and have it access
those members directory via its receiver value.
* Have startProfile() return an error instead of log.Fatal()ing. We can
simply propagate the error up the stack and let the caller handle the
error -- we shouldn't be exiting deep in the bowels of a non-main
package.
* Capture and return errors from pprof.StartCPUProfile(). Currently
there is only one possible error it can return but if it returns an
error, we should handle it.
* add CPUProfileWriteCloser and MemProfileWriteCloser to Server struct.
* make stopProfile() a method of Server
* remove prof variable
* fix captialization of log messages.
This PR lazily initializes Flux built-in functions when Flux is used.
It significantly reduces the startup time of the `influxd` and `influx`
binaries.

This integrates the influxdb 1.x series to the latest version of Flux
and updates the code to use it. It also removes the dependency on
platform and copies the necessary code from storage into the 1.x series
so the dependency is unneeded.
The flux functions specific to 1.x have been moved to the same structure
that flux changed to with having a `stdlib` directory instead of a
`functions` directory. It also adds a `databases()` function that
returns the databases from the meta client.
* Add AuthorizeDatabase API to QueryAuthorizer to verify a user has
appropriate access to the specified database
* Update serverFluxQuery handler to require a meta.User when auth is
enabled
* update Flux createFromSource and createBucketsSource dependencies to
require Authorizer when auth is enabled in configuration
* update createFromSource to verify read permissions for each bucket
specified in a Flux query
* update BucketsDecoder, which implements the buckets() Flux function,
to return buckets that the user has read or write permissions to
* add unit tests to verify authentication is required for Flux HTTP
requests when auth is enabled in configuration
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.
