+# xxhash
+
+[](https://godoc.org/github.com/cespare/xxhash)
+[](https://travis-ci.org/cespare/xxhash)
+
+xxhash is a Go implementation of the 64-bit
+[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
+high-quality hashing algorithm that is much faster than anything in the Go
+standard library.
+
+This package provides a straightforward API:
+
+```
+func Sum64(b []byte) uint64
+func Sum64String(s string) uint64
+type Digest struct{ ... }
+ func New() *Digest
+```
+
+The `Digest` type implements hash.Hash64. Its key methods are:
+
+```
+func (*Digest) Write([]byte) (int, error)
+func (*Digest) WriteString(string) (int, error)
+func (*Digest) Sum64() uint64
+```
+
+This implementation provides a fast pure-Go implementation and an even faster
+assembly implementation for amd64.
+
+## Compatibility
+
+This package is in a module and the latest code is in version 2 of the module.
+You need a version of Go with at least "minimal module compatibility" to use
+github.com/cespare/xxhash/v2:
+
+* 1.9.7+ for Go 1.9
+* 1.10.3+ for Go 1.10
+* Go 1.11 or later
+
+I recommend using the latest release of Go.
+
+## Benchmarks
+
+Here are some quick benchmarks comparing the pure-Go and assembly
+implementations of Sum64.
+
+| input size | purego | asm |
+| --- | --- | --- |
+| 5 B | 979.66 MB/s | 1291.17 MB/s |
+| 100 B | 7475.26 MB/s | 7973.40 MB/s |
+| 4 KB | 17573.46 MB/s | 17602.65 MB/s |
+| 10 MB | 17131.46 MB/s | 17142.16 MB/s |
+
+These numbers were generated on Ubuntu 18.04 with an Intel i7-8700K CPU using
+the following commands under Go 1.11.2:
+
+```
+$ go test -tags purego -benchtime 10s -bench '/xxhash,direct,bytes'
+$ go test -benchtime 10s -bench '/xxhash,direct,bytes'
+```

+// 1. A list of tests called guard. Each test in guard checks a single entry in the database. It may check
+// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
+// may apply to the same or different entries in the database. All tests in the guard are applied and
+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed
+// if guard evaluates to
+// true.
+// 3. A list of database operations called f op. Like t op, but executed if guard evaluates to false.

+// for the absence or presence of a value, or compare with a given value. Two different tests in the guard
+// may apply to the same or different entries in the database. All tests in the guard are applied and
+// MultiOp returns the results. If all tests are true, MultiOp executes t op (see item 2 below), otherwise
+// it executes f op (see item 3 below).
+// 2. A list of database operations called t op. Each operation in the list is either an insert, delete, or
+// lookup operation, and applies to a single database entry. Two different operations in the list may apply
+// to the same or different entries in the database. These operations are executed

+# Raft library
+
+Raft is a protocol with which a cluster of nodes can maintain a replicated state machine.
+The state machine is kept in sync through the use of a replicated log.
+For more details on Raft, see "In Search of an Understandable Consensus Algorithm"
+(https://ramcloud.stanford.edu/raft.pdf) by Diego Ongaro and John Ousterhout.
+
+This Raft library is stable and feature complete. As of 2016, it is **the most widely used** Raft library in production, serving tens of thousands clusters each day. It powers distributed systems such as etcd, Kubernetes, Docker Swarm, Cloud Foundry Diego, CockroachDB, TiDB, Project Calico, Flannel, and more.
+
+Most Raft implementations have a monolithic design, including storage handling, messaging serialization, and network transport. This library instead follows a minimalistic design philosophy by only implementing the core raft algorithm. This minimalism buys flexibility, determinism, and performance.
+
+To keep the codebase small as well as provide flexibility, the library only implements the Raft algorithm; both network and disk IO are left to the user. Library users must implement their own transportation layer for message passing between Raft peers over the wire. Similarly, users must implement their own storage layer to persist the Raft log and state.
+
+In order to easily test the Raft library, its behavior should be deterministic. To achieve this determinism, the library models Raft as a state machine. The state machine takes a `Message` as input. A message can either be a local timer update or a network message sent from a remote peer. The state machine's output is a 3-tuple `{[]Messages, []LogEntries, NextState}` consisting of an array of `Messages`, `log entries`, and `Raft state changes`. For state machines with the same state, the same state machine input should always generate the same state machine output.
+
+A simple example application, _raftexample_, is also available to help illustrate how to use this package in practice: https://github.com/coreos/etcd/tree/master/contrib/raftexample
+
+# Features
+
+This raft implementation is a full feature implementation of Raft protocol. Features includes:
+
+- Leader election
+- Log replication
+- Log compaction
+- Membership changes
+- Leadership transfer extension
+- Efficient linearizable read-only queries served by both the leader and followers
+ - leader checks with quorum and bypasses Raft log before processing read-only queries
+ - followers asks leader to get a safe read index before processing read-only queries
+- More efficient lease-based linearizable read-only queries served by both the leader and followers
+ - leader bypasses Raft log and processing read-only queries locally
+ - followers asks leader to get a safe read index before processing read-only queries
+ - this approach relies on the clock of the all the machines in raft group
+
+This raft implementation also includes a few optional enhancements:
+
+- Optimistic pipelining to reduce log replication latency
+- Flow control for log replication
+- Batching Raft messages to reduce synchronized network I/O calls
+- Batching log entries to reduce disk synchronized I/O
+- Writing to leader's disk in parallel
+- Internal proposal redirection from followers to leader
+- Automatic stepping down when the leader loses quorum

+
+## Usage
+
+The primary object in raft is a Node. Either start a Node from scratch using raft.StartNode or start a Node from some initial state using raft.RestartNode.
+
+To start a three-node cluster
+```go
+ storage := raft.NewMemoryStorage()
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+ // Set peer list to the other nodes in the cluster.
+ // Note that they need to be started separately as well.
+ n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
+```
+
+Start a single node cluster, like so:
+```go
+ // Create storage and config as shown above.
+ // Set peer list to itself, so this node can become the leader of this single-node cluster.
+ peers := []raft.Peer{{ID: 0x01}}
+ n := raft.StartNode(c, peers)
+```
+
+To allow a new node to join this cluster, do not pass in any peers. First, add the node to the existing cluster by calling `ProposeConfChange` on any existing node inside the cluster. Then, start the node with an empty peer list, like so:
+```go
+ // Create storage and config as shown above.
+ n := raft.StartNode(c, nil)
+```
+
+To restart a node from previous state:
+```go
+ storage := raft.NewMemoryStorage()
+
+ // Recover the in-memory storage from persistent snapshot, state and entries.
+ storage.ApplySnapshot(snapshot)
+ storage.SetHardState(state)
+ storage.Append(entries)
+
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+
+ // Restart raft without peer information.
+ // Peer information is already included in the storage.
+ n := raft.RestartNode(c)
+```
+
+After creating a Node, the user has a few responsibilities:
+
+First, read from the Node.Ready() channel and process the updates it contains. These steps may be performed in parallel, except as noted in step 2.
+
+1. Write Entries, HardState and Snapshot to persistent storage in order, i.e. Entries first, then HardState and Snapshot if they are not empty. If persistent storage supports atomic writes then all of them can be written together. Note that when writing an Entry with Index i, any previously-persisted entries with Index >= i must be discarded.
+
+2. Send all Messages to the nodes named in the To field. It is important that no messages be sent until the latest HardState has been persisted to disk, and all Entries written by any previous Ready batch (Messages may be sent while entries from the same batch are being persisted). To reduce the I/O latency, an optimization can be applied to make leader write to disk in parallel with its followers (as explained at section 10.2.1 in Raft thesis). If any Message has type MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be large). Note: Marshalling messages is not thread-safe; it is important to make sure that no new entries are persisted while marshalling. The easiest way to achieve this is to serialise the messages directly inside the main raft loop.
+
+3. Apply Snapshot (if any) and CommittedEntries to the state machine. If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange() to apply it to the node. The configuration change may be cancelled at this point by setting the NodeID field to zero before calling ApplyConfChange (but ApplyConfChange must be called one way or the other, and the decision to cancel must be based solely on the state machine and not external information such as the observed health of the node).
+
+4. Call Node.Advance() to signal readiness for the next batch of updates. This may be done at any time after step 1, although all updates must be processed in the order they were returned by Ready.
+
+Second, all persisted log entries must be made available via an implementation of the Storage interface. The provided MemoryStorage type can be used for this (if repopulating its state upon a restart), or a custom disk-backed implementation can be supplied.
+
+Third, after receiving a message from another node, pass it to Node.Step:
+
+```go
+ func recvRaftRPC(ctx context.Context, m raftpb.Message) {
+ n.Step(ctx, m)
+ }
+```
+
+Finally, call `Node.Tick()` at regular intervals (probably via a `time.Ticker`). Raft has two important timeouts: heartbeat and the election timeout. However, internally to the raft package time is represented by an abstract "tick".
+
+The total state machine handling loop will look something like this:
+
+```go
+ for {
+ select {
+ case <-s.Ticker:
+ n.Tick()
+ case rd := <-s.Node.Ready():
+ saveToStorage(rd.State, rd.Entries, rd.Snapshot)
+ send(rd.Messages)
+ if !raft.IsEmptySnap(rd.Snapshot) {
+ processSnapshot(rd.Snapshot)
+ }
+ for _, entry := range rd.CommittedEntries {
+ process(entry)
+ if entry.Type == raftpb.EntryConfChange {
+ var cc raftpb.ConfChange
+ cc.Unmarshal(entry.Data)
+ s.Node.ApplyConfChange(cc)
+ }
+ }
+ s.Node.Advance()
+ case <-s.done:
+ return
+ }
+ }
+```
+
+To propose changes to the state machine from the node to take application data, serialize it into a byte slice and call:
+
+```go
+ n.Propose(ctx, data)
+```
+
+If the proposal is committed, data will appear in committed entries with type raftpb.EntryNormal. There is no guarantee that a proposed command will be committed; the command may have to be reproposed after a timeout.
+
+To add or remove node in a cluster, build ConfChange struct 'cc' and call:
+
+```go
+ n.ProposeConfChange(ctx, cc)
+```
+
+After config change is committed, some committed entry with type raftpb.EntryConfChange will be returned. This must be applied to node through:
+
+```go
+ var cc raftpb.ConfChange
+ cc.Unmarshal(data)
+ n.ApplyConfChange(cc)
+```
+
+Note: An ID represents a unique node in a cluster for all time. A
+given ID MUST be used only once even if the old node has been removed.
+This means that for example IP addresses make poor node IDs since they
+may be reused. Node IDs must be non-zero.
+
+## Implementation notes
+
+This implementation is up to date with the final Raft thesis (https://ramcloud.stanford.edu/~ongaro/thesis.pdf), although this implementation of the membership change protocol differs somewhat from that described in chapter 4. The key invariant that membership changes happen one node at a time is preserved, but in our implementation the membership change takes effect when its entry is applied, not when it is added to the log (so the entry is committed under the old membership instead of the new). This is equivalent in terms of safety, since the old and new configurations are guaranteed to overlap.
+
+To ensure there is no attempt to commit two membership changes at once by matching log positions (which would be unsafe since they should have different quorum requirements), any proposed membership change is simply disallowed while any uncommitted change appears in the leader's log.
+
+This approach introduces a problem when removing a member from a two-member cluster: If one of the members dies before the other one receives the commit of the confchange entry, then the member cannot be removed any more since the cluster cannot make progress. For this reason it is highly recommended to use three or more nodes in every cluster.

+## Progress
+
+Progress represents a follower’s progress in the view of the leader. Leader maintains progresses of all followers, and sends `replication message` to the follower based on its progress.
+
+`replication message` is a `msgApp` with log entries.
+
+A progress has two attribute: `match` and `next`. `match` is the index of the highest known matched entry. If leader knows nothing about follower’s replication status, `match` is set to zero. `next` is the index of the first entry that will be replicated to the follower. Leader puts entries from `next` to its latest one in next `replication message`.
+
+A progress is in one of the three state: `probe`, `replicate`, `snapshot`.
+
+```
+ +--------------------------------------------------------+
+ | send snapshot |
+ | |
+ +---------+----------+ +----------v---------+
+ +---> probe | | snapshot |
+ | | max inflight = 1 <----------------------------------+ max inflight = 0 |
+ | +---------+----------+ +--------------------+
+ | | 1. snapshot success
+ | | (next=snapshot.index + 1)
+ | | 2. snapshot failure
+ | | (no change)
+ | | 3. receives msgAppResp(rej=false&&index>lastsnap.index)
+ | | (match=m.index,next=match+1)
+receives msgAppResp(rej=true)
+(next=match+1)| |
+ | |
+ | |
+ | | receives msgAppResp(rej=false&&index>match)
+ | | (match=m.index,next=match+1)
+ | |
+ | |
+ | |
+ | +---------v----------+
+ | | replicate |
+ +---+ max inflight = n |
+ +--------------------+
+```
+
+When the progress of a follower is in `probe` state, leader sends at most one `replication message` per heartbeat interval. The leader sends `replication message` slowly and probing the actual progress of the follower. A `msgHeartbeatResp` or a `msgAppResp` with reject might trigger the sending of the next `replication message`.
+
+When the progress of a follower is in `replicate` state, leader sends `replication message`, then optimistically increases `next` to the latest entry sent. This is an optimized state for fast replicating log entries to the follower.
+
+When the progress of a follower is in `snapshot` state, leader stops sending any `replication message`.
+
+A newly elected leader sets the progresses of all the followers to `probe` state with `match` = 0 and `next` = last index. The leader slowly (at most once per heartbeat) sends `replication message` to the follower and probes its progress.
+
+A progress changes to `replicate` when the follower replies with a non-rejection `msgAppResp`, which implies that it has matched the index sent. At this point, leader starts to stream log entries to the follower fast. The progress will fall back to `probe` when the follower replies a rejection `msgAppResp` or the link layer reports the follower is unreachable. We aggressively reset `next` to `match`+1 since if we receive any `msgAppResp` soon, both `match` and `next` will increase directly to the `index` in `msgAppResp`. (We might end up with sending some duplicate entries when aggressively reset `next` too low. see open question)
+
+A progress changes from `probe` to `snapshot` when the follower falls very far behind and requires a snapshot. After sending `msgSnap`, the leader waits until the success, failure or abortion of the previous snapshot sent. The progress will go back to `probe` after the sending result is applied.
+
+### Flow Control
+
+1. limit the max size of message sent per message. Max should be configurable.
+Lower the cost at probing state as we limit the size per message; lower the penalty when aggressively decreased to a too low `next`
+
+2. limit the # of in flight messages < N when in `replicate` state. N should be configurable. Most implementation will have a sending buffer on top of its actual network transport layer (not blocking raft node). We want to make sure raft does not overflow that buffer, which can cause message dropping and triggering a bunch of unnecessary resending repeatedly.

+
+Usage
+
+The primary object in raft is a Node. You either start a Node from scratch
+using raft.StartNode or start a Node from some initial state using raft.RestartNode.
+
+To start a node from scratch:
+
+ storage := raft.NewMemoryStorage()
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+ n := raft.StartNode(c, []raft.Peer{{ID: 0x02}, {ID: 0x03}})
+
+To restart a node from previous state:
+
+ storage := raft.NewMemoryStorage()
+
+ // recover the in-memory storage from persistent
+ // snapshot, state and entries.
+ storage.ApplySnapshot(snapshot)
+ storage.SetHardState(state)
+ storage.Append(entries)
+
+ c := &Config{
+ ID: 0x01,
+ ElectionTick: 10,
+ HeartbeatTick: 1,
+ Storage: storage,
+ MaxSizePerMsg: 4096,
+ MaxInflightMsgs: 256,
+ }
+
+ // restart raft without peer information.
+ // peer information is already included in the storage.
+ n := raft.RestartNode(c)
+
+Now that you are holding onto a Node you have a few responsibilities:
+
+First, you must read from the Node.Ready() channel and process the updates
+it contains. These steps may be performed in parallel, except as noted in step
+2.
+
+1. Write HardState, Entries, and Snapshot to persistent storage if they are
+not empty. Note that when writing an Entry with Index i, any
+previously-persisted entries with Index >= i must be discarded.
+
+2. Send all Messages to the nodes named in the To field. It is important that
+no messages be sent until the latest HardState has been persisted to disk,
+and all Entries written by any previous Ready batch (Messages may be sent while
+entries from the same batch are being persisted). To reduce the I/O latency, an
+optimization can be applied to make leader write to disk in parallel with its
+followers (as explained at section 10.2.1 in Raft thesis). If any Message has type
+MsgSnap, call Node.ReportSnapshot() after it has been sent (these messages may be
+large).
+
+Note: Marshalling messages is not thread-safe; it is important that you
+make sure that no new entries are persisted while marshalling.
+The easiest way to achieve this is to serialise the messages directly inside
+your main raft loop.
+
+3. Apply Snapshot (if any) and CommittedEntries to the state machine.
+If any committed Entry has Type EntryConfChange, call Node.ApplyConfChange()
+to apply it to the node. The configuration change may be cancelled at this point
+by setting the NodeID field to zero before calling ApplyConfChange
+(but ApplyConfChange must be called one way or the other, and the decision to cancel
+must be based solely on the state machine and not external information such as
+the observed health of the node).
+
+4. Call Node.Advance() to signal readiness for the next batch of updates.
+This may be done at any time after step 1, although all updates must be processed
+in the order they were returned by Ready.
+
+Second, all persisted log entries must be made available via an
+implementation of the Storage interface. The provided MemoryStorage
+type can be used for this (if you repopulate its state upon a
+restart), or you can supply your own disk-backed implementation.
+
+Third, when you receive a message from another node, pass it to Node.Step:
+
+ func recvRaftRPC(ctx context.Context, m raftpb.Message) {
+ n.Step(ctx, m)
+ }
+
+Finally, you need to call Node.Tick() at regular intervals (probably
+via a time.Ticker). Raft has two important timeouts: heartbeat and the
+election timeout. However, internally to the raft package time is
+represented by an abstract "tick".
+
+The total state machine handling loop will look something like this:
+
+ for {
+ select {
+ case <-s.Ticker:
+ n.Tick()
+ case rd := <-s.Node.Ready():
+ saveToStorage(rd.State, rd.Entries, rd.Snapshot)
+ send(rd.Messages)
+ if !raft.IsEmptySnap(rd.Snapshot) {
+ processSnapshot(rd.Snapshot)
+ }
+ for _, entry := range rd.CommittedEntries {
+ process(entry)
+ if entry.Type == raftpb.EntryConfChange {
+ var cc raftpb.ConfChange
+ cc.Unmarshal(entry.Data)
+ s.Node.ApplyConfChange(cc)
+ }
+ }
+ s.Node.Advance()
+ case <-s.done:
+ return
+ }
+ }
+
+To propose changes to the state machine from your node take your application
+data, serialize it into a byte slice and call:
+
+ n.Propose(ctx, data)
+
+If the proposal is committed, data will appear in committed entries with type
+raftpb.EntryNormal. There is no guarantee that a proposed command will be
+committed; you may have to re-propose after a timeout.
+
+To add or remove node in a cluster, build ConfChange struct 'cc' and call:
+
+ n.ProposeConfChange(ctx, cc)
+
+After config change is committed, some committed entry with type
+raftpb.EntryConfChange will be returned. You must apply it to node through:
+
+ var cc raftpb.ConfChange
+ cc.Unmarshal(data)
+ n.ApplyConfChange(cc)
+
+Note: An ID represents a unique node in a cluster for all time. A
+given ID MUST be used only once even if the old node has been removed.
+This means that for example IP addresses make poor node IDs since they
+may be reused. Node IDs must be non-zero.
+
+Implementation notes

+This implementation is up to date with the final Raft thesis

+This approach introduces a problem when you try to remove a member
+from a two-member cluster: If one of the members dies before the
+other one receives the commit of the confchange entry, then the member
+cannot be removed any more since the cluster cannot make progress.
+For this reason it is highly recommended to use three or more nodes in
+every cluster.
+
+MessageType
+
+Package raft sends and receives message in Protocol Buffer format (defined
+in raftpb package). Each state (follower, candidate, leader) implements its
+own 'step' method ('stepFollower', 'stepCandidate', 'stepLeader') when
+advancing with the given raftpb.Message. Each step is determined by its
+raftpb.MessageType. Note that every step is checked by one common method
+'Step' that safety-checks the terms of node and incoming message to prevent
+stale log entries:
+
+ 'MsgHup' is used for election. If a node is a follower or candidate, the
+ 'tick' function in 'raft' struct is set as 'tickElection'. If a follower or
+ candidate has not received any heartbeat before the election timeout, it
+ passes 'MsgHup' to its Step method and becomes (or remains) a candidate to
+ start a new election.
+
+ 'MsgBeat' is an internal type that signals the leader to send a heartbeat of
+ the 'MsgHeartbeat' type. If a node is a leader, the 'tick' function in
+ the 'raft' struct is set as 'tickHeartbeat', and triggers the leader to
+ send periodic 'MsgHeartbeat' messages to its followers.
+
+ 'MsgProp' proposes to append data to its log entries. This is a special
+ type to redirect proposals to leader. Therefore, send method overwrites
+ raftpb.Message's term with its HardState's term to avoid attaching its
+ local term to 'MsgProp'. When 'MsgProp' is passed to the leader's 'Step'
+ method, the leader first calls the 'appendEntry' method to append entries
+ to its log, and then calls 'bcastAppend' method to send those entries to
+ its peers. When passed to candidate, 'MsgProp' is dropped. When passed to
+ follower, 'MsgProp' is stored in follower's mailbox(msgs) by the send
+ method. It is stored with sender's ID and later forwarded to leader by
+ rafthttp package.
+
+ 'MsgApp' contains log entries to replicate. A leader calls bcastAppend,
+ which calls sendAppend, which sends soon-to-be-replicated logs in 'MsgApp'
+ type. When 'MsgApp' is passed to candidate's Step method, candidate reverts
+ back to follower, because it indicates that there is a valid leader sending
+ 'MsgApp' messages. Candidate and follower respond to this message in
+ 'MsgAppResp' type.
+
+ 'MsgAppResp' is response to log replication request('MsgApp'). When
+ 'MsgApp' is passed to candidate or follower's Step method, it responds by
+ calling 'handleAppendEntries' method, which sends 'MsgAppResp' to raft
+ mailbox.
+
+ 'MsgVote' requests votes for election. When a node is a follower or
+ candidate and 'MsgHup' is passed to its Step method, then the node calls
+ 'campaign' method to campaign itself to become a leader. Once 'campaign'
+ method is called, the node becomes candidate and sends 'MsgVote' to peers
+ in cluster to request votes. When passed to leader or candidate's Step
+ method and the message's Term is lower than leader's or candidate's,
+ 'MsgVote' will be rejected ('MsgVoteResp' is returned with Reject true).
+ If leader or candidate receives 'MsgVote' with higher term, it will revert
+ back to follower. When 'MsgVote' is passed to follower, it votes for the
+ sender only when sender's last term is greater than MsgVote's term or
+ sender's last term is equal to MsgVote's term but sender's last committed
+ index is greater than or equal to follower's.
+
+ 'MsgVoteResp' contains responses from voting request. When 'MsgVoteResp' is
+ passed to candidate, the candidate calculates how many votes it has won. If
+ it's more than majority (quorum), it becomes leader and calls 'bcastAppend'.
+ If candidate receives majority of votes of denials, it reverts back to
+ follower.
+
+ 'MsgPreVote' and 'MsgPreVoteResp' are used in an optional two-phase election
+ protocol. When Config.PreVote is true, a pre-election is carried out first
+ (using the same rules as a regular election), and no node increases its term
+ number unless the pre-election indicates that the campaigining node would win.
+ This minimizes disruption when a partitioned node rejoins the cluster.
+
+ 'MsgSnap' requests to install a snapshot message. When a node has just
+ become a leader or the leader receives 'MsgProp' message, it calls
+ 'bcastAppend' method, which then calls 'sendAppend' method to each
+ follower. In 'sendAppend', if a leader fails to get term or entries,
+ the leader requests snapshot by sending 'MsgSnap' type message.
+
+ 'MsgSnapStatus' tells the result of snapshot install message. When a
+ follower rejected 'MsgSnap', it indicates the snapshot request with
+ 'MsgSnap' had failed from network issues which causes the network layer
+ to fail to send out snapshots to its followers. Then leader considers
+ follower's progress as probe. When 'MsgSnap' were not rejected, it
+ indicates that the snapshot succeeded and the leader sets follower's
+ progress to probe and resumes its log replication.
+
+ 'MsgHeartbeat' sends heartbeat from leader. When 'MsgHeartbeat' is passed
+ to candidate and message's term is higher than candidate's, the candidate
+ reverts back to follower and updates its committed index from the one in
+ this heartbeat. And it sends the message to its mailbox. When
+ 'MsgHeartbeat' is passed to follower's Step method and message's term is
+ higher than follower's, the follower updates its leaderID with the ID
+ from the message.
+
+ 'MsgHeartbeatResp' is a response to 'MsgHeartbeat'. When 'MsgHeartbeatResp'
+ is passed to leader's Step method, the leader knows which follower
+ responded. And only when the leader's last committed index is greater than
+ follower's Match index, the leader runs 'sendAppend` method.
+
+ 'MsgUnreachable' tells that request(message) wasn't delivered. When
+ 'MsgUnreachable' is passed to leader's Step method, the leader discovers
+ that the follower that sent this 'MsgUnreachable' is not reachable, often
+ indicating 'MsgApp' is lost. When follower's progress state is replicate,
+ the leader sets it back to probe.

+# capnslog, the CoreOS logging package
+
+There are far too many logging packages out there, with varying degrees of licenses, far too many features (colorization, all sorts of log frameworks) or are just a pain to use (lack of `Fatalln()`?).
+capnslog provides a simple but consistent logging interface suitable for all kinds of projects.
+
+### Design Principles
+
+##### `package main` is the place where logging gets turned on and routed
+
+A library should not touch log options, only generate log entries. Libraries are silent until main lets them speak.
+
+##### All log options are runtime-configurable.
+
+Still the job of `main` to expose these configurations. `main` may delegate this to, say, a configuration webhook, but does so explicitly.
+
+##### There is one log object per package. It is registered under its repository and package name.
+
+`main` activates logging for its repository and any dependency repositories it would also like to have output in its logstream. `main` also dictates at which level each subpackage logs.
+
+##### There is *one* output stream, and it is an `io.Writer` composed with a formatter.
+
+Splitting streams is probably not the job of your program, but rather, your log aggregation framework. If you must split output streams, again, `main` configures this and you can write a very simple two-output struct that satisfies io.Writer.
+
+Fancy colorful formatting and JSON output are beyond the scope of a basic logging framework -- they're application/log-collector dependent. These are, at best, provided as options, but more likely, provided by your application.
+
+##### Log objects are an interface
+
+An object knows best how to print itself. Log objects can collect more interesting metadata if they wish, however, because text isn't going away anytime soon, they must all be marshalable to text. The simplest log object is a string, which returns itself. If you wish to do more fancy tricks for printing your log objects, see also JSON output -- introspect and write a formatter which can handle your advanced log interface. Making strings is the only thing guaranteed.
+
+##### Log levels have specific meanings:
+
+ * Critical: Unrecoverable. Must fail.
+ * Error: Data has been lost, a request has failed for a bad reason, or a required resource has been lost
+ * Warning: (Hopefully) Temporary conditions that may cause errors, but may work fine. A replica disappearing (that may reconnect) is a warning.
+ * Notice: Normal, but important (uncommon) log information.
+ * Info: Normal, working log information, everything is fine, but helpful notices for auditing or common operations.
+ * Debug: Everything is still fine, but even common operations may be logged, and less helpful but more quantity of notices.
+ * Trace: Anything goes, from logging every function call as part of a common operation, to tracing execution of a query.

+
+## Installation
+
+go-redis supports 2 last Go versions and requires a Go version with
+[modules](https://github.com/golang/go/wiki/Modules) support. So make sure to initialize a Go
+module:
+
+```shell
+go mod init github.com/my/repo
+```
+
+And then install go-redis (note _v8_ in the import; omitting it is a popular mistake):
+
+```shell
+go get github.com/go-redis/redis/v8
+```
+
+## Quickstart
+
+```go
+import (
+ "context"
+ "github.com/go-redis/redis/v8"
+)
+
+var ctx = context.Background()
+
+func ExampleClient() {
+ rdb := redis.NewClient(&redis.Options{
+ Addr: "localhost:6379",
+ Password: "", // no password set
+ DB: 0, // use default DB
+ })
+
+ err := rdb.Set(ctx, "key", "value", 0).Err()
+ if err != nil {
+ panic(err)
+ }
+
+ val, err := rdb.Get(ctx, "key").Result()
+ if err != nil {
+ panic(err)
+ }
+ fmt.Println("key", val)
+
+ val2, err := rdb.Get(ctx, "key2").Result()
+ if err == redis.Nil {
+ fmt.Println("key2 does not exist")
+ } else if err != nil {
+ panic(err)
+ } else {
+ fmt.Println("key2", val2)
+ }
+ // Output: key value
+ // key2 does not exist
+}
+```
+
+## Look and feel
+
+Some corner cases:
+
+```go
+// SET key value EX 10 NX
+set, err := rdb.SetNX(ctx, "key", "value", 10*time.Second).Result()
+
+// SET key value keepttl NX
+set, err := rdb.SetNX(ctx, "key", "value", redis.KeepTTL).Result()
+
+// SORT list LIMIT 0 2 ASC
+vals, err := rdb.Sort(ctx, "list", &redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
+
+// ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
+vals, err := rdb.ZRangeByScoreWithScores(ctx, "zset", &redis.ZRangeBy{
+ Min: "-inf",
+ Max: "+inf",
+ Offset: 0,
+ Count: 2,
+}).Result()
+
+// ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
+vals, err := rdb.ZInterStore(ctx, "out", &redis.ZStore{
+ Keys: []string{"zset1", "zset2"},
+ Weights: []int64{2, 3}
+}).Result()
+
+// EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
+vals, err := rdb.Eval(ctx, "return {KEYS[1],ARGV[1]}", []string{"key"}, "hello").Result()
+
+// custom command
+res, err := rdb.Do(ctx, "set", "key", "value").Result()
+```

+Package gogoproto provides extensions for protocol buffers to achieve:
+
+ - fast marshalling and unmarshalling.
+ - peace of mind by optionally generating test and benchmark code.
+ - more canonical Go structures.
+ - less typing by optionally generating extra helper code.
+ - goprotobuf compatibility
+
+More Canonical Go Structures
+
+A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
+You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
+Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
+
+ - nullable, if false, a field is generated without a pointer (see warning below).
+ - embed, if true, the field is generated as an embedded field.
+ - customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
+ - customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
+ - casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums.
+ - castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
+ - castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
+
+Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
+
+Let us look at:
+
+ github.com/gogo/protobuf/test/example/example.proto
+
+for a quicker overview.
+
+The following message:
+
+ package test;
+
+ import "github.com/gogo/protobuf/gogoproto/gogo.proto";
+
+ message A {
+ optional string Description = 1 [(gogoproto.nullable) = false];
+ optional int64 Number = 2 [(gogoproto.nullable) = false];
+ optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
+ }
+
+Will generate a go struct which looks a lot like this:
+
+ type A struct {
+ Description string
+ Number int64
+ Id github_com_gogo_protobuf_test_custom.Uuid
+ }
+
+You will see there are no pointers, since all fields are non-nullable.
+You will also see a custom type which marshals to a string.
+Be warned it is your responsibility to test your custom types thoroughly.
+You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
+
+Next we will embed the message A in message B.
+
+ message B {
+ optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
+ repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
+ }
+
+See below that A is embedded in B.
+
+ type B struct {
+ A
+ G []github_com_gogo_protobuf_test_custom.Uint128
+ }
+
+Also see the repeated custom type.
+
+ type Uint128 [2]uint64
+
+Next we will create a custom name for one of our fields.
+
+ message C {
+ optional int64 size = 1 [(gogoproto.customname) = "MySize"];
+ }
+
+See below that the field's name is MySize and not Size.
+
+ type C struct {
+ MySize *int64
+ }
+
+The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
+As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
+Using customname you can fix this error without changing the field name.
+This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
+
+Gogoprotobuf also has some more subtle changes, these could be changed back:
+
+ - the generated package name for imports do not have the extra /filename.pb,
+ but are actually the imports specified in the .proto file.
+
+Gogoprotobuf also has lost some features which should be brought back with time:
+
+ - Marshalling and unmarshalling with reflect and without the unsafe package,
+ this requires work in pointer_reflect.go
+
+Why does nullable break protocol buffer specifications:
+
+The protocol buffer specification states, somewhere, that you should be able to tell whether a
+field is set or unset. With the option nullable=false this feature is lost,
+since your non-nullable fields will always be set. It can be seen as a layer on top of
+protocol buffers, where before and after marshalling all non-nullable fields are set
+and they cannot be unset.
+
+Goprotobuf Compatibility:
+
+Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
+Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
+The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
+
+ - gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
+ - goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
+ - goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
+ - goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
+ - goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
+ - goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
+ - goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
+ - goproto_registration (beta), if true, the generated files will register all messages and types against both gogo/protobuf and golang/protobuf. This is necessary when using third-party packages which read registrations from golang/protobuf (such as the grpc-gateway).
+
+Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
+
+ - github.com/gogo/protobuf/plugin/<extension_name>
+
+If you do not use any of these extension the code that is generated
+will be the same as if goprotobuf has generated it.
+
+The most complete way to see examples is to look at
+
+ github.com/gogo/protobuf/test/thetest.proto
+
+Gogoprototest is a seperate project,
+because we want to keep gogoprotobuf independent of goprotobuf,
+but we still want to test it thoroughly.

+ and their corresponding elements are equal. Note a "bytes" field,
+ although represented by []byte, is not a repeated field and the
+ rule for the scalar fields described above applies.
+ - Two unset fields are equal.
+ - Two unknown field sets are equal if their current
+ encoded state is equal.
+ - Two extension sets are equal iff they have corresponding
+ elements that are pairwise equal.

+Package proto converts data structures to and from the wire format of
+protocol buffers. It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+ - Names are turned from camel_case to CamelCase for export.
+ - There are no methods on v to set fields; just treat
+ them as structure fields.
+ - There are getters that return a field's value if set,
+ and return the field's default value if unset.
+ The getters work even if the receiver is a nil message.
+ - The zero value for a struct is its correct initialization state.
+ All desired fields must be set before marshaling.
+ - A Reset() method will restore a protobuf struct to its zero state.
+ - Non-repeated fields are pointers to the values; nil means unset.
+ That is, optional or required field int32 f becomes F *int32.
+ - Repeated fields are slices.
+ - Helper functions are available to aid the setting of fields.
+ msg.Foo = proto.String("hello") // set field
+ - Constants are defined to hold the default values of all fields that
+ have them. They have the form Default_StructName_FieldName.
+ Because the getter methods handle defaulted values,
+ direct use of these constants should be rare.
+ - Enums are given type names and maps from names to values.
+ Enum values are prefixed by the enclosing message's name, or by the
+ enum's type name if it is a top-level enum. Enum types have a String
+ method, and a Enum method to assist in message construction.
+ - Nested messages, groups and enums have type names prefixed with the name of
+ the surrounding message type.
+ - Extensions are given descriptor names that start with E_,
+ followed by an underscore-delimited list of the nested messages
+ that contain it (if any) followed by the CamelCased name of the
+ extension field itself. HasExtension, ClearExtension, GetExtension
+ and SetExtension are functions for manipulating extensions.
+ - Oneof field sets are given a single field in their message,
+ with distinguished wrapper types for each possible field value.
+ - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+ - Non-repeated fields of non-message type are values instead of pointers.
+ - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+ package example;
+
+ enum FOO { X = 17; }
+
+ message Test {
+ required string label = 1;

+ // A Location identifies a piece of source code in a .proto file which
+ // corresponds to a particular definition. This information is intended
+ // to be useful to IDEs, code indexers, documentation generators, and similar
+ // tools.
+ //
+ // For example, say we have a file like:
+ // message Foo {
+ // optional string foo = 1;
+ // }
+ // Let's look at just the field definition:
+ // optional string foo = 1;
+ // ^ ^^ ^^ ^ ^^^
+ // a bc de f ghi
+ // We have the following locations:
+ // span path represents
+ // [a,i) [ 4, 0, 2, 0 ] The whole field definition.
+ // [a,b) [ 4, 0, 2, 0, 4 ] The label (optional).
+ // [c,d) [ 4, 0, 2, 0, 5 ] The type (string).
+ // [e,f) [ 4, 0, 2, 0, 1 ] The name (foo).
+ // [g,h) [ 4, 0, 2, 0, 3 ] The number (1).
+ //
+ // Notes:
+ // - A location may refer to a repeated field itself (i.e. not to any
+ // particular index within it). This is used whenever a set of elements are
+ // logically enclosed in a single code segment. For example, an entire
+ // extend block (possibly containing multiple extension definitions) will
+ // have an outer location whose path refers to the "extensions" repeated
+ // field without an index.
+ // - Multiple locations may have the same path. This happens when a single
+ // logical declaration is spread out across multiple places. The most
+ // obvious example is the "extend" block again -- there may be multiple
+ // extend blocks in the same scope, each of which will have the same path.
+ // - A location's span is not always a subset of its parent's span. For
+ // example, the "extendee" of an extension declaration appears at the
+ // beginning of the "extend" block and is shared by all extensions within
+ // the block.
+ // - Just because a location's span is a subset of some other location's span
+ // does not mean that it is a descendant. For example, a "group" defines
+ // both a type and a field in a single declaration. Thus, the locations
+ // corresponding to the type and field and their components will overlap.
+ // - Code which tries to interpret locations should probably be designed to
+ // ignore those that it doesn't understand, as more types of locations could
+ // be recorded in the future.

+# uuid 
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services.
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid). It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice. One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).
+
+###### Install
+`go get github.com/google/uuid`
+
+###### Documentation
+[](http://godoc.org/github.com/google/uuid)
+
+Full `go doc` style documentation for the package can be viewed online without
+installing this package by using the GoDoc site here:
+http://pkg.go.dev/github.com/google/uuid

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
+
+This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [0.13.0] - 2020-10-08
+
+### Added
+
+- OTLP Metric exporter supports Histogram aggregation. (#1209)
+- The `Code` struct from the `go.opentelemetry.io/otel/codes` package now supports JSON marshaling and unmarshaling as well as implements the `Stringer` interface. (#1214)
+- A Baggage API to implement the OpenTelemetry specification. (#1217)
+
+### Changed
+
+- Set default propagator to no-op propagator. (#1184)
+- The `HTTPSupplier`, `HTTPExtractor`, `HTTPInjector`, and `HTTPPropagator` from the `go.opentelemetry.io/otel/api/propagation` package were replaced with unified `TextMapCarrier` and `TextMapPropagator` in the `go.opentelemetry.io/otel` package. (#1212)
+- The `New` function from the `go.opentelemetry.io/otel/api/propagation` package was replaced with `NewCompositeTextMapPropagator` in the `go.opentelemetry.io/otel` package. (#1212)
+- The status codes of the `go.opentelemetry.io/otel/codes` package have been updated to match the latest OpenTelemetry specification.
+ They now are `Unset`, `Error`, and `Ok`.
+ They no longer track the gRPC codes. (#1214)
+- The `StatusCode` field of the `SpanData` struct in the `go.opentelemetry.io/otel/sdk/export/trace` package now uses the codes package from this package instead of the gRPC project. (#1214)
+- Move the `go.opentelemetry.io/otel/api/baggage` package into `go.opentelemetry.io/otel/propagators`. (#1217)
+
+### Fixed
+
+- Copies of data from arrays and slices passed to `go.opentelemetry.io/otel/label.ArrayValue()` are now used in the returned `Value` instead of using the mutable data itself. (#1226)
+
+### Removed
+
+- The `ExtractHTTP` and `InjectHTTP` functions from the `go.opentelemetry.io/otel/api/propagation` package were removed. (#1212)
+- The `Propagators` interface from the `go.opentelemetry.io/otel/api/propagation` package was removed to conform to the OpenTelemetry specification.
+ The explicit `TextMapPropagator` type can be used in its place as this is the `Propagator` type the specification defines. (#1212)
+- The `SetAttribute` method of the `Span` from the `go.opentelemetry.io/otel/api/trace` package was removed given its redundancy with the `SetAttributes` method. (#1216)
+- The internal implementation of Baggage storage is removed in favor of using the new Baggage API functionality. (#1217)
+- Remove duplicate hostname key `HostHostNameKey` in Resource semantic conventions. (#1219)
+- Nested array/slice support has been removed. (#1226)
+
+## [0.12.0] - 2020-09-24
+
+### Added
+
+- A `SpanConfigure` function in `go.opentelemetry.io/otel/api/trace` to create a new `SpanConfig` from `SpanOption`s. (#1108)
+- In the `go.opentelemetry.io/otel/api/trace` package, `NewTracerConfig` was added to construct new `TracerConfig`s.
+ This addition was made to conform with our project option conventions. (#1155)
+- Instrumentation library information was added to the Zipkin exporter. (#1119)
+- The `SpanProcessor` interface now has a `ForceFlush()` method. (#1166)
+- More semantic conventions for k8s as resource attributes. (#1167)
+
+### Changed
+
+- Add reconnecting udp connection type to Jaeger exporter.
+ This change adds a new optional implementation of the udp conn interface used to detect changes to an agent's host dns record.
+ It then adopts the new destination address to ensure the exporter doesn't get stuck. This change was ported from jaegertracing/jaeger-client-go#520. (#1063)
+- Replace `StartOption` and `EndOption` in `go.opentelemetry.io/otel/api/trace` with `SpanOption`.
+ This change is matched by replacing the `StartConfig` and `EndConfig` with a unified `SpanConfig`. (#1108)
+- Replace the `LinkedTo` span option in `go.opentelemetry.io/otel/api/trace` with `WithLinks`.
+ This is be more consistent with our other option patterns, i.e. passing the item to be configured directly instead of its component parts, and provides a cleaner function signature. (#1108)
+- The `go.opentelemetry.io/otel/api/trace` `TracerOption` was changed to an interface to conform to project option conventions. (#1109)
+- Move the `B3` and `TraceContext` from within the `go.opentelemetry.io/otel/api/trace` package to their own `go.opentelemetry.io/otel/propagators` package.
+ This removal of the propagators is reflective of the OpenTelemetry specification for these propagators as well as cleans up the `go.opentelemetry.io/otel/api/trace` API. (#1118)
+- Rename Jaeger tags used for instrumentation library information to reflect changes in OpenTelemetry specification. (#1119)
+- Rename `ProbabilitySampler` to `TraceIDRatioBased` and change semantics to ignore parent span sampling status. (#1115)
+- Move `tools` package under `internal`. (#1141)
+- Move `go.opentelemetry.io/otel/api/correlation` package to `go.opentelemetry.io/otel/api/baggage`. (#1142)
+ The `correlation.CorrelationContext` propagator has been renamed `baggage.Baggage`. Other exported functions and types are unchanged.
+- Rename `ParentOrElse` sampler to `ParentBased` and allow setting samplers depending on parent span. (#1153)
+- In the `go.opentelemetry.io/otel/api/trace` package, `SpanConfigure` was renamed to `NewSpanConfig`. (#1155)
+- Change `dependabot.yml` to add a `Skip Changelog` label to dependabot-sourced PRs. (#1161)
+- The [configuration style guide](https://github.com/open-telemetry/opentelemetry-go/blob/master/CONTRIBUTING.md#config) has been updated to
+ recommend the use of `newConfig()` instead of `configure()`. (#1163)
+- The `otlp.Config` type has been unexported and changed to `otlp.config`, along with its initializer. (#1163)
+- Ensure exported interface types include parameter names and update the
+ Style Guide to reflect this styling rule. (#1172)
+- Don't consider unset environment variable for resource detection to be an error. (#1170)
+- Rename `go.opentelemetry.io/otel/api/metric.ConfigureInstrument` to `NewInstrumentConfig` and
+ `go.opentelemetry.io/otel/api/metric.ConfigureMeter` to `NewMeterConfig`.
+- ValueObserver instruments use LastValue aggregator by default. (#1165)
+- OTLP Metric exporter supports LastValue aggregation. (#1165)
+- Move the `go.opentelemetry.io/otel/api/unit` package to `go.opentelemetry.io/otel/unit`. (#1185)
+- Rename `Provider` to `MeterProvider` in the `go.opentelemetry.io/otel/api/metric` package. (#1190)
+- Rename `NoopProvider` to `NoopMeterProvider` in the `go.opentelemetry.io/otel/api/metric` package. (#1190)
+- Rename `NewProvider` to `NewMeterProvider` in the `go.opentelemetry.io/otel/api/metric/metrictest` package. (#1190)
+- Rename `Provider` to `MeterProvider` in the `go.opentelemetry.io/otel/api/metric/registry` package. (#1190)
+- Rename `NewProvider` to `NewMeterProvider` in the `go.opentelemetry.io/otel/api/metri/registryc` package. (#1190)
+- Rename `Provider` to `TracerProvider` in the `go.opentelemetry.io/otel/api/trace` package. (#1190)
+- Rename `NoopProvider` to `NoopTracerProvider` in the `go.opentelemetry.io/otel/api/trace` package. (#1190)
+- Rename `Provider` to `TracerProvider` in the `go.opentelemetry.io/otel/api/trace/tracetest` package. (#1190)
+- Rename `NewProvider` to `NewTracerProvider` in the `go.opentelemetry.io/otel/api/trace/tracetest` package. (#1190)
+- Rename `WrapperProvider` to `WrapperTracerProvider` in the `go.opentelemetry.io/otel/bridge/opentracing` package. (#1190)
+- Rename `NewWrapperProvider` to `NewWrapperTracerProvider` in the `go.opentelemetry.io/otel/bridge/opentracing` package. (#1190)
+- Rename `Provider` method of the pull controller to `MeterProvider` in the `go.opentelemetry.io/otel/sdk/metric/controller/pull` package. (#1190)
+- Rename `Provider` method of the push controller to `MeterProvider` in the `go.opentelemetry.io/otel/sdk/metric/controller/push` package. (#1190)

+- Integration tests for more OTel Collector Attribute types. (#1062)
+- A new `WithSpanProcessor` `ProviderOption` is added to the `go.opentelemetry.io/otel/sdk/trace` package to create a `Provider` and automatically register the `SpanProcessor`. (#1078)
+
+### Changed
+
+- Rename `sdk/metric/processor/test` to `sdk/metric/processor/processortest`. (#1049)
+- Rename `sdk/metric/controller/test` to `sdk/metric/controller/controllertest`. (#1049)
+- Rename `api/testharness` to `api/apitest`. (#1049)
+- Rename `api/trace/testtrace` to `api/trace/tracetest`. (#1049)
+- Change Metric Processor to merge multiple observations. (#1024)
+- The `go.opentelemetry.io/otel/bridge/opentracing` bridge package has been made into its own module.
+ This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038)
+- Renamed `go.opentelemetry.io/otel/api/standard` package to `go.opentelemetry.io/otel/semconv` to avoid the ambiguous and generic name `standard` and better describe the package as containing OpenTelemetry semantic conventions. (#1016)

+- Unify Callback Function Naming.
+ Rename `*Callback` with `*Func`. (#1061)
+- CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064)
+- The `go.opentelemetry.io/otel/sdk/export/trace` interfaces `SpanSyncer` and `SpanBatcher` have been replaced with a specification compliant `Exporter` interface.
+ This interface still supports the export of `SpanData`, but only as a slice.
+ Implementation are also required now to return any error from `ExportSpans` if one occurs as well as implement a `Shutdown` method for exporter clean-up. (#1078)
+- The `go.opentelemetry.io/otel/sdk/trace` `NewBatchSpanProcessor` function no longer returns an error.
+ If a `nil` exporter is passed as an argument to this function, instead of it returning an error, it now returns a `BatchSpanProcessor` that handles the export of `SpanData` by not taking any action. (#1078)
+- The `go.opentelemetry.io/otel/sdk/trace` `NewProvider` function to create a `Provider` no longer returns an error, instead only a `*Provider`.
+ This change is related to `NewBatchSpanProcessor` not returning an error which was the only error this function would return. (#1078)
+
+### Removed
+
+- Duplicate, unused API sampler interface. (#999)
+ Use the [`Sampler` interface](https://github.com/open-telemetry/opentelemetry-go/blob/v0.11.0/sdk/trace/sampling.go) provided by the SDK instead.
+- The `grpctrace` instrumentation was moved to the `go.opentelemetry.io/contrib` repository and out of this repository.
+ This move includes moving the `grpc` example to the `go.opentelemetry.io/contrib` as well. (#1027)
+- The `WithSpan` method of the `Tracer` interface.
+ The functionality this method provided was limited compared to what a user can provide themselves.
+ It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043)
+- The `RegisterSpanProcessor` and `UnregisterSpanProcessor` functions.
+ These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077)
+- The `oterror` package. (#1026)
+- The `othttp` and `httptrace` instrumentations were moved to `go.opentelemetry.io/contrib`. (#1032)
+
+### Fixed
+
+- The `semconv.HTTPServerMetricAttributesFromHTTPRequest()` function no longer generates the high-cardinality `http.request.content.length` label. (#1031)
+- Correct instrumentation version tag in Jaeger exporter. (#1037)
+- The SDK span will now set an error event if the `End` method is called during a panic (i.e. it was deferred). (#1043)
+- Move internally generated protobuf code from the `go.opentelemetry.io/otel` to the OTLP exporter to reduce dependency overhead. (#1050)
+- The `otel-collector` example referenced outdated collector processors. (#1006)
+
+## [0.10.0] - 2020-07-29
+
+This release migrates the default OpenTelemetry SDK into its own Go module, decoupling the SDK from the API and reducing dependencies for instrumentation packages.
+
+### Added
+
+- The Zipkin exporter now has `NewExportPipeline` and `InstallNewPipeline` constructor functions to match the common pattern.
+ These function build a new exporter with default SDK options and register the exporter with the `global` package respectively. (#944)
+- Add propagator option for gRPC instrumentation. (#986)
+- The `testtrace` package now tracks the `trace.SpanKind` for each span. (#987)
+
+### Changed
+
+- Replace the `RegisterGlobal` `Option` in the Jaeger exporter with an `InstallNewPipeline` constructor function.
+ This matches the other exporter constructor patterns and will register a new exporter after building it with default configuration. (#944)
+- The trace (`go.opentelemetry.io/otel/exporters/trace/stdout`) and metric (`go.opentelemetry.io/otel/exporters/metric/stdout`) `stdout` exporters are now merged into a single exporter at `go.opentelemetry.io/otel/exporters/stdout`.
+ This new exporter was made into its own Go module to follow the pattern of all exporters and decouple it from the `go.opentelemetry.io/otel` module. (#956, #963)
+- Move the `go.opentelemetry.io/otel/exporters/test` test package to `go.opentelemetry.io/otel/sdk/export/metric/metrictest`. (#962)
+- The `go.opentelemetry.io/otel/api/kv/value` package was merged into the parent `go.opentelemetry.io/otel/api/kv` package. (#968)
+ - `value.Bool` was replaced with `kv.BoolValue`.
+ - `value.Int64` was replaced with `kv.Int64Value`.
+ - `value.Uint64` was replaced with `kv.Uint64Value`.
+ - `value.Float64` was replaced with `kv.Float64Value`.
+ - `value.Int32` was replaced with `kv.Int32Value`.
+ - `value.Uint32` was replaced with `kv.Uint32Value`.
+ - `value.Float32` was replaced with `kv.Float32Value`.
+ - `value.String` was replaced with `kv.StringValue`.
+ - `value.Int` was replaced with `kv.IntValue`.
+ - `value.Uint` was replaced with `kv.UintValue`.
+ - `value.Array` was replaced with `kv.ArrayValue`.
+- Rename `Infer` to `Any` in the `go.opentelemetry.io/otel/api/kv` package. (#972)
+- Change `othttp` to use the `httpsnoop` package to wrap the `ResponseWriter` so that optional interfaces (`http.Hijacker`, `http.Flusher`, etc.) that are implemented by the original `ResponseWriter`are also implemented by the wrapped `ResponseWriter`. (#979)
+- Rename `go.opentelemetry.io/otel/sdk/metric/aggregator/test` package to `go.opentelemetry.io/otel/sdk/metric/aggregator/aggregatortest`. (#980)
+- Make the SDK into its own Go module called `go.opentelemetry.io/otel/sdk`. (#985)
+- Changed the default trace `Sampler` from `AlwaysOn` to `ParentOrElse(AlwaysOn)`. (#989)
+
+### Removed
+
+- The `IndexedAttribute` function from the `go.opentelemetry.io/otel/api/label` package was removed in favor of `IndexedLabel` which it was synonymous with. (#970)
+
+### Fixed
+
+- Bump github.com/golangci/golangci-lint from 1.28.3 to 1.29.0 in /tools. (#953)
+- Bump github.com/google/go-cmp from 0.5.0 to 0.5.1. (#957)
+- Use `global.Handle` for span export errors in the OTLP exporter. (#946)
+- Correct Go language formatting in the README documentation. (#961)
+- Remove default SDK dependencies from the `go.opentelemetry.io/otel/api` package. (#977)
+- Remove default SDK dependencies from the `go.opentelemetry.io/otel/instrumentation` package. (#983)
+- Move documented examples for `go.opentelemetry.io/otel/instrumentation/grpctrace` interceptors into Go example tests. (#984)
+
+## [0.9.0] - 2020-07-20
+
+### Added
+
+- A new Resource Detector interface is included to allow resources to be automatically detected and included. (#939)
+- A Detector to automatically detect resources from an environment variable. (#939)
+- Github action to generate protobuf Go bindings locally in `internal/opentelemetry-proto-gen`. (#938)
+- OTLP .proto files from `open-telemetry/opentelemetry-proto` imported as a git submodule under `internal/opentelemetry-proto`.
+ References to `github.com/open-telemetry/opentelemetry-proto` changed to `go.opentelemetry.io/otel/internal/opentelemetry-proto-gen`. (#942)
+
+### Changed
+
+- Non-nil value `struct`s for key-value pairs will be marshalled using JSON rather than `Sprintf`. (#948)
+
+### Removed
+
+- Removed dependency on `github.com/open-telemetry/opentelemetry-collector`. (#943)
+
+## [0.8.0] - 2020-07-09
+
+### Added
+
+- The `B3Encoding` type to represent the B3 encoding(s) the B3 propagator can inject.
+ A value for HTTP supported encodings (Multiple Header: `MultipleHeader`, Single Header: `SingleHeader`) are included. (#882)
+- The `FlagsDeferred` trace flag to indicate if the trace sampling decision has been deferred. (#882)
+- The `FlagsDebug` trace flag to indicate if the trace is a debug trace. (#882)
+- Add `peer.service` semantic attribute. (#898)
+- Add database-specific semantic attributes. (#899)
+- Add semantic convention for `faas.coldstart` and `container.id`. (#909)
+- Add http content size semantic conventions. (#905)
+- Include `http.request_content_length` in HTTP request basic attributes. (#905)
+- Add semantic conventions for operating system process resource attribute keys. (#919)
+- The Jaeger exporter now has a `WithBatchMaxCount` option to specify the maximum number of spans sent in a batch. (#931)
+
+### Changed
+
+- Update `CONTRIBUTING.md` to ask for updates to `CHANGELOG.md` with each pull request. (#879)
+- Use lowercase header names for B3 Multiple Headers. (#881)
+- The B3 propagator `SingleHeader` field has been replaced with `InjectEncoding`.
+ This new field can be set to combinations of the `B3Encoding` bitmasks and will inject trace information in these encodings.
+ If no encoding is set, the propagator will default to `MultipleHeader` encoding. (#882)
+- The B3 propagator now extracts from either HTTP encoding of B3 (Single Header or Multiple Header) based on what is contained in the header.
+ Preference is given to Single Header encoding with Multiple Header being the fallback if Single Header is not found or is invalid.
+ This behavior change is made to dynamically support all correctly encoded traces received instead of having to guess the expected encoding prior to receiving. (#882)
+- Extend semantic conventions for RPC. (#900)
+- To match constant naming conventions in the `api/standard` package, the `FaaS*` key names are appended with a suffix of `Key`. (#920)
+ - `"api/standard".FaaSName` -> `FaaSNameKey`
+ - `"api/standard".FaaSID` -> `FaaSIDKey`
+ - `"api/standard".FaaSVersion` -> `FaaSVersionKey`
+ - `"api/standard".FaaSInstance` -> `FaaSInstanceKey`
+
+### Removed
+
+- The `FlagsUnused` trace flag is removed.
+ The purpose of this flag was to act as the inverse of `FlagsSampled`, the inverse of `FlagsSampled` is used instead. (#882)
+- The B3 header constants (`B3SingleHeader`, `B3DebugFlagHeader`, `B3TraceIDHeader`, `B3SpanIDHeader`, `B3SampledHeader`, `B3ParentSpanIDHeader`) are removed.
+ If B3 header keys are needed [the authoritative OpenZipkin package constants](https://pkg.go.dev/github.com/openzipkin/zipkin-go@v0.2.2/propagation/b3?tab=doc#pkg-constants) should be used instead. (#882)
+
+### Fixed
+
+- The B3 Single Header name is now correctly `b3` instead of the previous `X-B3`. (#881)
+- The B3 propagator now correctly supports sampling only values (`b3: 0`, `b3: 1`, or `b3: d`) for a Single B3 Header. (#882)
+- The B3 propagator now propagates the debug flag.
+ This removes the behavior of changing the debug flag into a set sampling bit.
+ Instead, this now follow the B3 specification and omits the `X-B3-Sampling` header. (#882)
+- The B3 propagator now tracks "unset" sampling state (meaning "defer the decision") and does not set the `X-B3-Sampling` header when injecting. (#882)
+- Bump github.com/itchyny/gojq from 0.10.3 to 0.10.4 in /tools. (#883)
+- Bump github.com/opentracing/opentracing-go from v1.1.1-0.20190913142402-a7454ce5950e to v1.2.0. (#885)
+- The tracing time conversion for OTLP spans is now correctly set to `UnixNano`. (#896)
+- Ensure span status is not set to `Unknown` when no HTTP status code is provided as it is assumed to be `200 OK`. (#908)
+- Ensure `httptrace.clientTracer` closes `http.headers` span. (#912)
+- Prometheus exporter will not apply stale updates or forget inactive metrics. (#903)
+- Add test for api.standard `HTTPClientAttributesFromHTTPRequest`. (#905)
+- Bump github.com/golangci/golangci-lint from 1.27.0 to 1.28.1 in /tools. (#901, #913)
+- Update otel-colector example to use the v0.5.0 collector. (#915)
+- The `grpctrace` instrumentation uses a span name conforming to the OpenTelemetry semantic conventions (does not contain a leading slash (`/`)). (#922)
+- The `grpctrace` instrumentation includes an `rpc.method` attribute now set to the gRPC method name. (#900, #922)
+- The `grpctrace` instrumentation `rpc.service` attribute now contains the package name if one exists.
+ This is in accordance with OpenTelemetry semantic conventions. (#922)
+- Correlation Context extractor will no longer insert an empty map into the returned context when no valid values are extracted. (#923)
+- Bump google.golang.org/api from 0.28.0 to 0.29.0 in /exporters/trace/jaeger. (#925)
+- Bump github.com/itchyny/gojq from 0.10.4 to 0.11.0 in /tools. (#926)
+- Bump github.com/golangci/golangci-lint from 1.28.1 to 1.28.2 in /tools. (#930)
+
+## [0.7.0] - 2020-06-26
+
+This release implements the v0.5.0 version of the OpenTelemetry specification.
+
+### Added
+
+- The othttp instrumentation now includes default metrics. (#861)
+- This CHANGELOG file to track all changes in the project going forward.
+- Support for array type attributes. (#798)
+- Apply transitive dependabot go.mod dependency updates as part of a new automatic Github workflow. (#844)
+- Timestamps are now passed to exporters for each export. (#835)
+- Add new `Accumulation` type to metric SDK to transport telemetry from `Accumulator`s to `Processor`s.
+ This replaces the prior `Record` `struct` use for this purpose. (#835)
+- New dependabot integration to automate package upgrades. (#814)
+- `Meter` and `Tracer` implementations accept instrumentation version version as an optional argument.
+ This instrumentation version is passed on to exporters. (#811) (#805) (#802)
+- The OTLP exporter includes the instrumentation version in telemetry it exports. (#811)
+- Environment variables for Jaeger exporter are supported. (#796)
+- New `aggregation.Kind` in the export metric API. (#808)
+- New example that uses OTLP and the collector. (#790)
+- Handle errors in the span `SetName` during span initialization. (#791)
+- Default service config to enable retries for retry-able failed requests in the OTLP exporter and an option to override this default. (#777)
+- New `go.opentelemetry.io/otel/api/oterror` package to uniformly support error handling and definitions for the project. (#778)
+- New `global` default implementation of the `go.opentelemetry.io/otel/api/oterror.Handler` interface to be used to handle errors prior to an user defined `Handler`.
+ There is also functionality for the user to register their `Handler` as well as a convenience function `Handle` to handle an error with this global `Handler`(#778)
+- Options to specify propagators for httptrace and grpctrace instrumentation. (#784)
+- The required `application/json` header for the Zipkin exporter is included in all exports. (#774)

+- Rename `simple` integrator to `basic` integrator. (#857)
+- Merge otlp collector examples. (#841)
+- Change the metric SDK to support cumulative, delta, and pass-through exporters directly.
+ With these changes, cumulative and delta specific exporters are able to request the correct kind of aggregation from the SDK. (#840)
+- The `Aggregator.Checkpoint` API is renamed to `SynchronizedCopy` and adds an argument, a different `Aggregator` into which the copy is stored. (#812)
+- The `export.Aggregator` contract is that `Update()` and `SynchronizedCopy()` are synchronized with each other.
+ All the aggregation interfaces (`Sum`, `LastValue`, ...) are not meant to be synchronized, as the caller is expected to synchronize aggregators at a higher level after the `Accumulator`.
+ Some of the `Aggregators` used unnecessary locking and that has been cleaned up. (#812)
+- Use of `metric.Number` was replaced by `int64` now that we use `sync.Mutex` in the `MinMaxSumCount` and `Histogram` `Aggregators`. (#812)
+- Replace `AlwaysParentSample` with `ParentSample(fallback)` to match the OpenTelemetry v0.5.0 specification. (#810)
+- Rename `sdk/export/metric/aggregator` to `sdk/export/metric/aggregation`. #808
+- Send configured headers with every request in the OTLP exporter, instead of just on connection creation. (#806)
+- Update error handling for any one off error handlers, replacing, instead, with the `global.Handle` function. (#791)
+- Rename `plugin` directory to `instrumentation` to match the OpenTelemetry specification. (#779)
+- Makes the argument order to Histogram and DDSketch `New()` consistent. (#781)
+
+### Removed

+- The default port the OTLP exporter uses to connect to the OpenTelemetry collector is updated to match the one the collector listens on by default. (#611)
+
+
+## [0.4.2] - 2020-03-31
+
+### Fixed
+
+- Fix `pre_release.sh` to update version in `sdk/opentelemetry.go`. (#607)

+
+## [0.4.0] - 2020-03-30
+
+### Added
+
+- New API package `api/metric/registry` that exposes a `MeterImpl` wrapper for use by SDKs to generate unique instruments. (#580)

+
+### Removed
+

+There is still a possibility of breaking changes.
+
+### Added
+
+- Add `Observer` metric instrument. (#474)
+- Add global `Propagators` functionality to enable deferred initialization for propagators registered before the first Meter SDK is installed. (#494)
+- Simplified export setup pipeline for the jaeger exporter to match other exporters. (#459)
+- The zipkin trace exporter. (#495)

+- The `StatusMessage` field was add to the trace `Span`. (#524)
+- Context propagation in OpenTracing bridge in terms of OpenTelemetry context propagation. (#525)
+- The `Resource` type was added to the SDK. (#528)
+- The global API now supports a `Tracer` and `Meter` function as shortcuts to getting a global `*Provider` and calling these methods directly. (#538)
+- The metric API now defines a generic `MeterImpl` interface to support general purpose `Meter` construction.
+ Additionally, `SyncImpl` and `AsyncImpl` are added to support general purpose instrument construction. (#560)
+- A metric `Kind` is added to represent the `MeasureKind`, `ObserverKind`, and `CounterKind`. (#560)
+- Scripts to better automate the release process. (#576)
+
+### Changed
+
+- Default to to use `AlwaysSampler` instead of `ProbabilitySampler` to match OpenTelemetry specification. (#506)
+- Renamed `AlwaysSampleSampler` to `AlwaysOnSampler` in the trace API. (#511)
+- Renamed `NeverSampleSampler` to `AlwaysOffSampler` in the trace API. (#511)
+- The `Status` field of the `Span` was changed to `StatusCode` to disambiguate with the added `StatusMessage`. (#524)
+- Updated the trace `Sampler` interface conform to the OpenTelemetry specification. (#531)
+- Rename metric API `Options` to `Config`. (#541)
+- Rename metric `Counter` aggregator to be `Sum`. (#541)
+- Unify metric options into `Option` from instrument specific options. (#541)
+- The trace API's `TraceProvider` now support `Resource`s. (#545)
+- Correct error in zipkin module name. (#548)
+- The jaeger trace exporter now supports `Resource`s. (#551)
+- Metric SDK now supports `Resource`s.
+ The `WithResource` option was added to configure a `Resource` on creation and the `Resource` method was added to the metric `Descriptor` to return the associated `Resource`. (#552)
+- Replace `ErrNoLastValue` and `ErrEmptyDataSet` by `ErrNoData` in the metric SDK. (#557)
+- The stdout trace exporter now supports `Resource`s. (#558)
+- The metric `Descriptor` is now included at the API instead of the SDK. (#560)
+- Replace `Ordered` with an iterator in `export.Labels`. (#567)
+
+### Removed
+
+- The vendor specific Stackdriver. It is now hosted on 3rd party vendor infrastructure. (#452)
+- The `Unregister` method for metric observers as it is not in the OpenTelemetry specification. (#560)
+- `GetDescriptor` from the metric SDK. (#575)
+- The `Gauge` instrument from the metric API. (#537)
+
+### Fixed
+
+- Make histogram aggregator checkpoint consistent. (#438)
+- Update README with import instructions and how to build and test. (#505)
+- The default label encoding was updated to be unique. (#508)
+- Use `NewRoot` in the othttp plugin for public endpoints. (#513)
+- Fix data race in `BatchedSpanProcessor`. (#518)
+- Skip test-386 for Mac OS 10.15.x (Catalina and upwards). #521
+- Use a variable-size array to represent ordered labels in maps. (#523)

+- Add filters to the othttp plugin. (#556)
+- Provide an implementation of the `Header*` filters that do not depend on Go 1.14. (#565)
+- Encode labels once during checkpoint.
+ The checkpoint function is executed in a single thread so we can do the encoding lazily before passing the encoded version of labels to the exporter.
+ This is a cheap and quick way to avoid encoding the labels on every collection interval. (#572)
+- Run coverage over all packages in `COVERAGE_MOD_DIR`. (#573)
+
+## [0.2.3] - 2020-03-04
+
+### Added
+
+- `RecordError` method on `Span`s in the trace API to Simplify adding error events to spans. (#473)
+- Configurable push frequency for exporters setup pipeline. (#504)
+
+### Changed
+
+- Rename the `exporter` directory to `exporters`.
+ The `go.opentelemetry.io/otel/exporter/trace/jaeger` package was mistakenly released with a `v1.0.0` tag instead of `v0.1.0`.
+ This resulted in all subsequent releases not becoming the default latest.
+ A consequence of this was that all `go get`s pulled in the incompatible `v0.1.0` release of that package when pulling in more recent packages from other otel packages.
+ Renaming the `exporter` directory to `exporters` fixes this issue by renaming the package and therefore clearing any existing dependency tags.
+ Consequentially, this action also renames *all* exporter packages. (#502)
+
+### Removed
+
+- The `CorrelationContextHeader` constant in the `correlation` package is no longer exported. (#503)
+
+## [0.2.2] - 2020-02-27
+
+### Added
+
+- `HTTPSupplier` interface in the propagation API to specify methods to retrieve and store a single value for a key to be associated with a carrier. (#467)

+- `Config` and configuring `Option` to the propagator API. (#467)
+- `Propagators` interface in the propagation API to contain the set of injectors and extractors for all supported carrier formats. (#467)
+- `HTTPPropagator` interface in the propagation API to inject and extract from an `HTTPSupplier.` (#467)
+- `WithInjectors` and `WithExtractors` functions to the propagator API to configure injectors and extractors to use. (#467)

+- Renamed the `export` package to `metric` to match directory structure. (#432)
+- Rename the `api/distributedcontext` package to `api/correlation`. (#444)
+- Rename the `api/propagators` package to `api/propagation`. (#444)
+- Move the propagators from the `propagators` package into the `trace` API package. (#444)
+- Update `Float64Gauge`, `Int64Gauge`, `Float64Counter`, `Int64Counter`, `Float64Measure`, and `Int64Measure` metric methods to use value receivers instead of pointers. (#462)
+- Moved all dependencies of tools package to a tools directory. (#466)
+
+### Removed
+
+- Binary propagators. (#467)
+- NOOP propagator. (#467)

+- Reword function documentation in gRPC plugin. (#446)
+- Send the `span.kind` tag to Jaeger from the jaeger exporter. (#441)

+# Contributing to opentelemetry-go
+
+The Go special interest group (SIG) meets regularly. See the
+OpenTelemetry
+[community](https://github.com/open-telemetry/community#golang-sdk)
+repo for information on this and other language SIGs.
+
+See the [public meeting
+notes](https://docs.google.com/document/d/1A63zSWX0x2CyCK_LoNhmQC4rqhLpYXJzXbEPDUQ2n6w/edit#heading=h.9tngw7jdwd6b)
+for a summary description of past meetings. To request edit access,
+join the meeting or get in touch on
+[Gitter](https://gitter.im/open-telemetry/opentelemetry-go).
+
+## Development
+
+You can view and edit the source code by cloning this repository:
+
+```bash
+git clone https://github.com/open-telemetry/opentelemetry-go.git
+```
+
+Run `make test` to run the tests instead of `go test`.
+
+There are some generated files checked into the repo. To make sure
+that the generated files are up-to-date, run `make` (or `make
+precommit` - the `precommit` target is the default).
+
+The `precommit` target also fixes the formatting of the code and
+checks the status of the go module files.
+
+If after running `make precommit` the output of `git status` contains
+`nothing to commit, working tree clean` then it means that everything
+is up-to-date and properly formatted.
+

+(This may print some warning about "build constraints exclude all Go
+files", just ignore it.)
+
+This will put the project in `${GOPATH}/src/go.opentelemetry.io/otel`. You
+can alternatively use `git` directly with:
+
+```sh
+$ git clone https://github.com/open-telemetry/opentelemetry-go
+```
+
+(Note that `git clone` is *not* using the `go.opentelemetry.io/otel` name -
+that name is a kind of a redirector to GitHub that `go get` can
+understand, but `git` does not.)
+
+This would put the project in the `opentelemetry-go` directory in
+current working directory.
+
+Enter the newly created directory and add your fork as a new remote:
+
+```sh
+$ git remote add <YOUR_FORK> git@github.com:<YOUR_GITHUB_USERNAME>/opentelemetry-go
+```
+
+Check out a new branch, make modifications, run linters and tests, update
+`CHANGELOG.md`, and push the branch to your fork:
+
+```sh
+$ git checkout -b <YOUR_BRANCH_NAME>
+# edit files
+# update changelog
+$ make precommit
+$ git add -p
+$ git commit
+$ git push <YOUR_FORK> <YOUR_BRANCH_NAME>
+```
+
+Open a pull request against the main `opentelemetry-go` repo. Be sure to add the pull
+request ID to the entry you added to `CHANGELOG.md`.
+
+### How to Receive Comments
+
+* If the PR is not ready for review, please put `[WIP]` in the title,
+ tag it as `work-in-progress`, or mark it as
+ [`draft`](https://github.blog/2019-02-14-introducing-draft-pull-requests/).
+* Make sure CLA is signed and CI is clear.
+
+### How to Get PRs Merged
+
+A PR is considered to be **ready to merge** when:
+
+* It has received two approvals from Collaborators/Maintainers (at
+ different companies). This is not enforced through technical means
+ and a PR may be **ready to merge** with a single approval if the change
+ and its approach have been discussed and consensus reached.
+* Major feedbacks are resolved.
+* It has been open for review for at least one working day. This gives
+ people reasonable time to review.
+* Trivial changes (typo, cosmetic, doc, etc.) do not have to wait for
+ one day and may be merged with a single Maintainer's approval.
+* `CHANGELOG.md` has been updated to reflect what has been
+ added, changed, removed, or fixed.
+* Urgent fix can take exception as long as it has been actively
+ communicated.
+
+Any Maintainer can merge the PR once it is **ready to merge**.
+
+## Design Choices
+
+As with other OpenTelemetry clients, opentelemetry-go follows the
+[opentelemetry-specification](https://github.com/open-telemetry/opentelemetry-specification).
+
+It's especially valuable to read through the [library
+guidelines](https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/library-guidelines.md).
+
+### Focus on Capabilities, Not Structure Compliance
+
+OpenTelemetry is an evolving specification, one where the desires and
+use cases are clear, but the method to satisfy those uses cases are
+not.
+
+As such, Contributions should provide functionality and behavior that
+conforms to the specification, but the interface and structure is
+flexible.
+
+It is preferable to have contributions follow the idioms of the
+language rather than conform to specific API names or argument
+patterns in the spec.
+
+For a deeper discussion, see:
+https://github.com/open-telemetry/opentelemetry-specification/issues/165
+
+## Style Guide
+
+One of the primary goals of this project is that it is actually used by
+developers. With this goal in mind the project strives to build
+user-friendly and idiomatic Go code adhering to the Go community's best
+practices.
+
+For a non-comprehensive but foundational overview of these best practices
+the [Effective Go](https://golang.org/doc/effective_go.html) documentation
+is an excellent starting place.
+
+As a convenience for developers building this project the `make precommit`
+will format, lint, validate, and in some cases fix the changes you plan to
+submit. This check will need to pass for your changes to be able to be
+merged.
+
+In addition to idiomatic Go, the project has adopted certain standards for
+implementations of common patterns. These standards should be followed as a
+default, and if they are not followed documentation needs to be included as
+to the reasons why.
+
+### Configuration
+
+When creating an instantiation function for a complex `struct` it is useful
+to allow variable number of options to be applied. However, the strong type
+system of Go restricts the function design options. There are a few ways to
+solve this problem, but we have landed on the following design.
+
+#### `config`
+
+Configuration should be held in a `struct` named `config`, or prefixed with
+specific type name this Configuration applies to if there are multiple
+`config` in the package. This `struct` must contain configuration options.
+
+```go
+// config contains configuration options for a thing.
+type config struct {
+ // options ...
+}
+```
+
+In general the `config` `struct` will not need to be used externally to the
+package and should be unexported. If, however, it is expected that the user
+will likely want to build custom options for the configuration, the `config`
+should be exported. Please, include in the documentation for the `config`
+how the user can extend the configuration.
+
+It is important that `config` are not shared across package boundaries.
+Meaning a `config` from one package should not be directly used by another.
+
+Optionally, it is common to include a `newConfig` function (with the same
+naming scheme). This function wraps any defaults setting and looping over
+all options to create a configured `config`.
+
+```go
+// newConfig returns an appropriately configured config.
+func newConfig([]Option) config {
+ // Set default values for config.
+ config := config{/* […] */}
+ for _, option := range options {
+ option.Apply(&config)
+ }
+ // Preform any validation here.
+ return config
+}
+```
+
+If validation of the `config` options is also preformed this can return an
+error as well that is expected to be handled by the instantiation function
+or propagated to the user.
+
+Given the design goal of not having the user need to work with the `config`,
+the `newConfig` function should also be unexported.
+
+#### `Option`
+
+To set the value of the options a `config` contains, a corresponding
+`Option` interface type should be used.
+
+```go
+type Option interface {
+ Apply(*config)
+}
+```
+
+The name of the interface should be prefixed in the same way the
+corresponding `config` is (if at all).
+
+#### Options
+
+All user configurable options for a `config` must have a related unexported
+implementation of the `Option` interface and an exported configuration
+function that wraps this implementation.
+
+The wrapping function name should be prefixed with `With*` (or in the
+special case of a boolean options `Without*`) and should have the following
+function signature.
+
+```go
+func With*(…) Option { … }
+```
+
+##### `bool` Options
+
+```go
+type defaultFalseOption bool
+
+func (o defaultFalseOption) Apply(c *config) {
+ c.Bool = bool(o)
+}
+
+// WithOption sets a T* to have an option included.
+func WithOption() Option {
+ return defaultFalseOption(true)
+}
+```
+
+```go
+type defaultTrueOption bool
+
+func (o defaultTrueOption) Apply(c *config) {
+ c.Bool = bool(o)
+}
+
+// WithoutOption sets a T* to have Bool option excluded.
+func WithoutOption() Option {
+ return defaultTrueOption(false)
+}
+````
+
+##### Declared Type Options
+
+```go
+type myTypeOption struct {
+ MyType MyType
+}
+
+func (o myTypeOption) Apply(c *config) {
+ c.MyType = o.MyType
+}
+
+// WithMyType sets T* to have include MyType.
+func WithMyType(t MyType) Option {
+ return myTypeOption{t}
+}
+```
+
+#### Instantiation
+
+Using this configuration pattern to configure instantiation with a `New*`
+function.
+
+```go
+func NewT*(options ...Option) T* {…}
+```
+
+Any required parameters can be declared before the variadic `options`.
+
+#### Dealing with Overlap
+
+Sometimes there are multiple complex `struct` that share common
+configuration and also have distinct configuration. To avoid repeated
+portions of `config`s, a common `config` can be used with the union of
+options being handled with the `Option` interface.
+
+For example.
+
+```go
+// config holds options for all animals.
+type config struct {
+ Weight float64
+ Color string
+ MaxAltitude float64
+}
+
+// DogOption apply Dog specific options.
+type DogOption interface {
+ ApplyDog(*config)
+}
+
+// BirdOption apply Bird specific options.
+type BirdOption interface {
+ ApplyBird(*config)
+}
+
+// Option apply options for all animals.
+type Option interface {
+ BirdOption
+ DogOption
+}
+
+type weightOption float64
+func (o weightOption) ApplyDog(c *config) { c.Weight = float64(o) }
+func (o weightOption) ApplyBird(c *config) { c.Weight = float64(o) }
+func WithWeight(w float64) Option { return weightOption(w) }
+
+type furColorOption string
+func (o furColorOption) ApplyDog(c *config) { c.Color = string(o) }
+func WithFurColor(c string) DogOption { return furColorOption(c) }
+
+type maxAltitudeOption float64
+func (o maxAltitudeOption) ApplyBird(c *config) { c.MaxAltitude = float64(o) }
+func WithMaxAltitude(a float64) BirdOption { return maxAltitudeOption(a) }
+
+func NewDog(name string, o ...DogOption) Dog {…}
+func NewBird(name string, o ...BirdOption) Bird {…}
+```
+
+### Interface Type
+
+To allow other developers to better comprehend the code, it is important
+to ensure it is sufficiently documented. One simple measure that contributes
+to this aim is self-documenting by naming method parameters. Therefore,
+where appropriate, methods of every exported interface type should have
+their parameters appropriately named.

+
+The Go [OpenTelemetry](https://opentelemetry.io/) implementation.
+
+## Getting Started
+
+OpenTelemetry's goal is to provide a single set of APIs to capture distributed
+traces and metrics from your application and send them to an observability
+platform. This project allows you to do just that for applications written in
+Go. There are two steps to this process: instrument your application, and
+configure an exporter.
+
+### Instrumentation
+
+To start capturing distributed traces and metric events from your application
+it first needs to be instrumented. The easiest way to do this is by using an
+instrumentation library for your code. Be sure to check out [the officially
+supported instrumentation
+libraries](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/master/instrumentation).
+
+If you need to extend the telemetry an instrumentation library provides or want
+to build your own instrumentation for your application directly you will need
+to use the
+[go.opentelemetry.io/otel/api](https://pkg.go.dev/go.opentelemetry.io/otel/api)
+package. The included [examples](./example/) are a good way to see some
+practical uses of this process.
+
+### Export
+
+Now that your application is instrumented to collect telemetry, it needs an
+export pipeline to send that telemetry to an observability platform.
+
+You can find officially supported exporters [here](./exporters/) and in the
+companion [contrib
+repository](https://github.com/open-telemetry/opentelemetry-go-contrib/tree/master/exporters/metric).
+Additionally, there are many vendor specific or 3rd party exporters for
+OpenTelemetry. These exporters are broken down by
+[trace](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/trace?tab=importedby)
+and
+[metric](https://pkg.go.dev/go.opentelemetry.io/otel/sdk/export/metric?tab=importedby)
+support.
+
+## Project Status
+
+[Project boards](https://github.com/open-telemetry/opentelemetry-go/projects)
+and [milestones](https://github.com/open-telemetry/opentelemetry-go/milestones)
+can be found at the respective links. We try to keep these accurate and should
+be the best place to go for answers on project status.

+# Release Process
+
+## Pre-Release
+
+Update go.mod for submodules to depend on the new release which will happen in the next step.
+
+1. Run the pre-release script. It creates a branch `pre_release_<new tag>` that will contain all release changes.
+
+ ```
+ ./pre_release.sh -t <new tag>
+ ```
+
+2. Verify the changes.
+
+ ```
+ git diff master
+ ```
+
+ This should have changed the version for all modules to be `<new tag>`.
+
+3. Update the [Changelog](./CHANGELOG.md).
+ - Make sure all relevant changes for this release are included and are in language that non-contributors to the project can understand.
+ To verify this, you can look directly at the commits since the `<last tag>`.
+
+ ```
+ git --no-pager log --pretty=oneline "<last tag>..HEAD"
+ ```
+
+ - Move all the `Unreleased` changes into a new section following the title scheme (`[<new tag>] - <date of release>`).
+ - Update all the appropriate links at the bottom.
+
+4. Push the changes to upstream and create a Pull Request on GitHub.
+ Be sure to include the curated changes from the [Changelog](./CHANGELOG.md) in the description.
+
+
+## Tag
+
+Once the Pull Request with all the version changes has been approved and merged it is time to tag the merged commit.
+
+***IMPORTANT***: It is critical you use the same tag that you used in the Pre-Release step!
+Failure to do so will leave things in a broken state.
+
+***IMPORTANT***: [There is currently no way to remove an incorrectly tagged version of a Go module](https://github.com/golang/go/issues/34189).
+It is critical you make sure the version you push upstream is correct.
+[Failure to do so will lead to minor emergencies and tough to work around](https://github.com/open-telemetry/opentelemetry-go/issues/331).
+
+1. Run the tag.sh script using the `<commit-hash>` of the commit on the master branch for the merged Pull Request.
+
+ ```
+ ./tag.sh <new tag> <commit-hash>
+ ```
+
+2. Push tags to the upstream remote (not your fork: `github.com/open-telemetry/opentelemetry-go.git`).
+ Make sure you push all sub-modules as well.
+
+ ```
+ git push upstream <new tag>
+ git push upstream <submodules-path/new tag>
+ ...
+ ```
+
+## Release
+
+Finally create a Release for the new `<new tag>` on GitHub.
+The release body should include all the release notes from the Changelog for this release.
+Additionally, the `tag.sh` script generates commit logs since last release which can be used to supplement the release notes.
+
+## Verify Examples
+
+After releasing verify that examples build outside of the repository.
+
+```
+./verify_examples.sh
+```
+
+The script copies examples into a different directory removes any `replace` declarations in `go.mod` and builds them.
+This ensures they build with the published release, not the local copy.
+
+## Contrib Repository
+
+Once verified be sure to [make a release for the `contrib` repository](https://github.com/open-telemetry/opentelemetry-go-contrib/blob/master/RELEASING.md) that uses this release.
