The first entry in the log is a dummy which is used for matchTerm
but may not have an actual payload. This change permits Storage
implementations to treat this term value specially instead of
storing it as a dummy Entry.
Storage.FirstIndex() no longer includes the term-only entry.
This reverses a recent decision to create entry zero as initially
unstable; Storage implementations are now required to make
Term(0) == 0 and the first unstable entry is now index 1.
stableTo(0) is no longer allowed.
Fixes all updates since bcwaldon sketched the original, with cleanup and
into an acutal working state. The commit log follows:
fix pb reference and remove unused file post rebase
unbreak the migrate folder
correctly detect node IDs
fix snapshotting
Fix previous broken snapshot
Add raft log entries to the translation; fix test for all timezones. (Still in progress, but passing)
Fix etcd:join and etcd:remove
print more data when dumping the log
Cleanup based on yichengq's comments
more comments
Fix the commited index based on the snapshot, if one exists
detect nodeIDs from snapshot
add initial tool documentation and match the semantics in the build script and main
formalize migration doc
rename function and clarify docs
fix nil pointer
fix the record conversion test
add migration to test suite and fix govet
We start etcd server in this test without the cluster. Sometimes it panics when
accessing the cluster. Most of the time it does not panic, since we can stop the
server fast enough before applying the first configuration change entry.
Stop should be idempotent. It should simply send a stop signal to the server.
It is the server's responsibility to stop the go-routines and related components.
* coreos/master:
etcdserver: add sender tests
raft: Only call stableTo when we have ready entries or a snapshot.
etcdserver: add ID() function to the Server interface.
sender: use RoundTripper instead of Client in sender

*: support updating advertise-peer-url Users might want to update the peerurl of the etcd member in several cases. For example, if the IP address of the physical machine etcd running on is changed, user need to update the adversite-pee-rurl accordingly. This commit makes etcd support updating the advertise-peer-url of its members.
transport: create a tls listener only if the tlsInfo is not empty and the scheme is HTTPS
etcdserver: use member pointer for all tests

This entry is now persisted through the normal flow instead of appearing
in the stored log at creation time. This is how things worked before
the Storage interface was introduced. (see coreos/etcd#1689)
This adds a check to setupCluster to ensure that the list of URLs
specified in `initial-advertise-peer-urls` matches those configured in
`initial-cluster` for this node. Also updates the documentation to
clarify this and address some changes in wording.
Users might want to update the peerurl of the etcd member in several cases.
For example, if the IP address of the physical machine etcd running on is
changed, user need to update the adversite-pee-rurl accordingly.
This commit makes etcd support updating the advertise-peer-url of its members.
This change splits the raftLog.entries array into an in-memory
"unstable" list and a pluggable interface for retrieving entries that
have been persisted to disk. An in-memory implementation of this
interface is provided which behaves the same as the old version;
in a future commit etcdserver could replace the MemoryStorage with
one backed by the WAL.
