Constants

const AlreadyExists = 442

Error when something other than a stream already exists

const AmbiguousStream = 418

When create() is called and although the uuid is different, the tags are not unique

const AmbiguousTags = 412

If a set of tags is given to identify a single stream, but fails to do so

const AnnotationTooBig = 422

Annotations cannot exceed 2MB

const AnnotationVersionMismatch = 423

The annotation version did not match

const AwesomenessExceedsThreshold = 410

Just in case

const BadSQLValue = 441

Generic error when bad parameters are passed to metadata db

const BadValue = 425

Returned when you try insert NaN or Inf values

const BlazeIt = 420

Just in case this is required after Prop 64

const CephError = 432

Generic error from ceph

const ClusterDegraded = 419

When a write op on an unmapped UUID is attempted

const ConcurrentModification = 430

Returned if you try delete a stream while its attributes are being modified

const ContextError = 402

Things like user timeout

const EtcdFailure = 428

Returned when the etcd cluster is unhealthy

const FaultInjectionDisabled = 424

Fault injection is disabled (you need $BTRDB_ENABLE_FAULT_INJECTON=YES)

const GenericError = 416

When an error has no code

const InsertFailure = 403

Like tree depth

const InsertTooBig = 414

The insertion is too big (that's what she said)

const InvalidCollection = 407

Collection name is invalid

const InvalidLimit = 411

For commands accepting a limit argument, the passed limit is invalid

const InvalidParameter = 438

You sent the wrong thing to an API endpoint

const InvalidPointWidth = 415

Point widths are [0, 64)

const InvalidTagKey = 408

Tag key is invalid

const InvalidTagValue = 409

Tag value is invalid

const InvalidTimeRange = 413

The start/end times are invalid

const InvalidVersions = 427

Returned when you try do changed ranges with bad versions

const InvariantFailure = 500

Used for assert statements

const JournalError = 434

Generic error returned when journalling

const ManifestDeviceDoesntExist = 439

When you try delete a manifest device that does not exist

const ManifestDeviceDuplicated = 436

Returned when there is a duplicate device

const ManifestError = 435

Errors when manipulating the manifest

const MetadataConnectionError = 440

Metadata database failure (like connection failure)

const MissingParameter = 443

Error when a key in a parameter map is missing

const NoSuchPoint = 401

If you ask for next/prev point but there isn't one

const NoSuchStream = 404

const NodeExisted = 433

Means that a node ID is reused, as of BTrDB 4.8 a node id must be unique

const NotImplemented = 501

Haha lol

const ObjectInUse = 446

Error when you try delete an object but it is still in use

const ObjectNotFound = 445

Error when a non-stream object is not found

const ObliterateDisabled = 431

Returned if you try to obliterate a stream on a node where BTRDB_ENABLE_OBLITERATE is not set to "YES"

const OperationNotAllowed = 447

When you try an operation that is not permitted by the current configuration

const ResourceDepleted = 426

Used when the cluster is extremely overloaded and is shedding load to maintain stability

const ReusedUUID = 429

Returned if you try create a stream with a uuid that is the same as a previously deleted stream

const SameStream = 417

When create() is called and the uuid is the same as an existing stream

const SelectorError = 449

Error when interacting with a selector

const StreamExists = 406

The stream already exists

const TLSError = 448

When there is an error with TLS certificates

const Unauthorized = 437

User does not have the right permissions

const UnrecognizedParameter = 444

Error when there is a key in a parameter map that is unrecognized

const WrongArgs = 421

Generated in drivers when the arguments are the wrong type or length

const WrongEndpoint = 405

We don't have a write lock for this stream

Functions

func Chan

func Chan(e BTE) chan BTE

func ChkContextError

func ChkContextError(ctx context.Context, rve chan BTE) bool

Context errors cascade quite a bit and tend to cause duplicate errors in the return channel. Try not to leak goroutiens by] blocking on them

func NoBlockError

func NoBlockError(e BTE, ch chan BTE)

Types

type BTE

type BTE interface {
	error

func Err

func Err(code int, reason string) BTE

func ErrF
