v1.6.0 (Jan 2024)

MySQL: Changes to Subtree Revisions

Support for skipping subtree revisions to increase read performance and reduce disk usage: added in #3201

TL;DR: existing trees will continue to be stored and queried as they were before, but new trees created with the MySQL storage layer will be stored and queried in a way that uses less space and allows for simpler and faster queries. No schema changes are required by log operators.

The Trillian MySQL implementation stores the internal state of the log as Subtrees in the database. These are essentially tiles as described by tlog: Tiling a log. Trees created with previous versions of Trillian stored a different revision of each Subtree when the tree was updated. This is somewhat redundant for append-only logs because an earlier version of a Subtree can always be derived from a later one by simply removing entries from the right of the Subtree. PR #3201 removes this Subtree revision history, and updates Subtrees in place when they are updated.

Measurements from @n-canter show that revisionless storage saves around 75% storage costs for the Subtree table, and queries over this table are more than 15% faster.

The same schema is used for both revisioned and unrevisioned subtrees. The difference is that we always write a revision of 0 in the unrevisioned case, which still means that there will only be a single entry per subtree.

Support is maintained for the old way of revisioning Subtrees in order to avoid breaking changes to existing trees. There is no simple code change that would safely allow a previously revisioned tree to start becoming a revisionless tree. This new revisionless Subtree feature is only available for trees created with new versions of Trillian.

Users with legacy revisioned trees that wish to take advantage of smaller storage costs and faster queries of the new revisionless storage should come speak to us on transparency-dev Slack. The safest option we have available is to use migrillian to create a new copy of trees, but this will be quite a manual process and will only work for CT logs. Other migration options are conceivable and we're eager to work with the community to develop and test tools for upgrading trees in place.

Notable Changes

CI now runs with MySQL 8.2 instead of MySQL 5.7
Bump golangci-lint from 1.51.1 to 1.55.1 (developers should update to this version)

- This is the version used by the cloudbuild presubmits. Using a different version can lead to presubmits failing due to unexpected diffs.

Storage

CloudSpanner

Removed use of the --cloudspanner_write_sessions flag. This was related to preparing some fraction of CloudSpanner sessionpool entries with Read/Write transactions, however this functionality is no longer supported by the client library.

v.1.5.0

Storage

Ephemeral nodes are no-longer written for any tree by default (and have not been read since the v1.4.0 release), the corresponding --tree_ids_with_no_ephemeral_nodes flag is now deprecated (and will be removed in a future release).

Cleanup

Dependency updates

Updated golangci-lint to v1.46.1 (developers should update to this version)
Removed dependency on certificate-transparency-go

Developer updates

#2765 copies the required protos from googleapis into third_party in this repository. This simplifies the preconditions in order to compile the proto definitions, and removes a big dependency on $GOPATH/src which was archaic; $GOPATH/src/github.com/googleapis/googleapis is no longer required.

v1.4.1

countFromInformationSchema function to add support for MySQL 8.

Removals

#2710: Unused storage/tools/dumplib was removed. The useful storage format regression test moved to integration/format.
#2711: Unused storage/tools/hasher removed.
#2715: Packages under merkle are deprecated and to be removed. Use https://github.com/transparency-dev/merkle instead.

Dependency updates

#2731: Update protoc from v3.12.4 to v3.20.1

v1.4.0

Recommended go version for development: 1.17
- This is the version used by the cloudbuild presubmits. Using a different version can lead to presubmits failing due to unexpected diffs.
GCP terraform script updated. GKE 1.19 and updated CPU type to E2

Dependency updates

Many dep updates, including:

Upgraded to etcd v3 in order to allow grpc to be upgraded (#2195)
- etcd was v0.5.0-alpha.5, now v3.5.0

MySQL driver from 1.5.0 to 1.6.0

Cleanup

Removed signatures from LogRoot and EntryTimestamps returned by RPCs (reflecting that there should not be a trust boundary between Trillian and the personality.)
Removed the deprecated crypto.NewSHA256Signer function.
Finish removing the LogMetadata.GetUnsequencedCounts() method.
Removed the following APIs:
- TrillianLog.GetLeavesByHash
- TrillianLog.GetLeavesByIndex
- TrillianLog.QueueLeaves
Removed the incomplete Postgres storage backend (#1298).
Deprecated LogRootV1.Revision field.
Moved rfc6962 hasher one directory up to eliminate empty leftover package.
Removed unused log_client tool.
Various tidyups and improvements to merke & proof generation code.
Remove some remnants of experimental map.

Storage refactoring

NodeReader.GetMerkleNodes does not accept revisions anymore. The implementations must use the transaction's ReadRevision instead.
TreeStorage migrated to using compact.NodeID type suitable for logs.
Removed the tree storage ReadRevision and WriteRevision methods. Revisions are now an implementation detail of the current storages. The change allows log implementations which don't need revisions.
Removed Rollback methods from storage interfaces, as Close is enough to cover the use-case.
Removed the unused IsOpen and IsClosed methods from transaction interfaces.
Removed the ReadOnlyLogTX interface, and put its only used GetActiveLogIDs method to LogStorage.
Inlined the LogMetadata interface to ReadOnlyLogStorage.
Inlined the TreeStorage interfaces to LogStorage.
Removed the need for the storage layer to return ephemeral node hashes. The application layer always requests for complete subtree nodes comprising the compact ranges corresponding to the requests.
Removed the single-tile callback from SubtreeCache, it uses only GetSubtreesFunc now.
Removed SetSubtreesFunc callback from SubtreeCache. The tiles should be written by the caller now, i.e. the caller must invoke the callback.

v1.3.13

Published 2021-02-16

Cleanup

Removed the experimental map API.

v1.3.12

Published 2021-02-16

Misc improvements

Removed unused PeekTokens method from the quota.Manager interface.
Ensure goroutines never block in the subtree cache (#2272).
Breaking unnecessary dependencies for Trillian clients:
- Moved verifiers from merkle into merkle/{log,map}verifiersub-pacakges, reducing the amount of extra baggage inadvertently pulled in by clients.
Concrete hashers have been moved into subpackages, separating them from their registration code, allowing clients to directly pull just the hasher they're interested in and avoid the Trillian/hasher registry+protobuf deps.
Moved some packages intended for internal-only use into internal packages:
- InMemoryMerkleTree (indended to only be used by Trillian tests)
Removed wrapper for etcd client (#2288).
Moved --quota_system and --storage_system flags to main.go so that they are initialised properly. It might break depending builds relying on these flags. Suggested fix: add the flags to main.go.
Made signer tolerate mastership election failures [#1150].
testdb no longer accepts the --test_mysql_uri flag, and instead honours the TEST_MYSQL_URI ENV var. This makes it easier to blanket configure tests to use a specific test DB instance.
Removed experimental Skylog folder (#2297).
Fixed a race condition in the operation manager that should only affect tests (#2302).
Run gofumpt formatter on the whole repository (#2315).
Refactor signer operation loop (#2294).

v1.3.11

Published 2020-10-06

Documentation

Added docs which describe the Claimant Model of transparency, a useful framework for reasoning about the design and architecture of transparent systems.

Misc improvements

Fixed int to string conversion warnings for golang 1.15
Metric improvements for fetched leaf counts

stackdriver from 0.13.2 to 0.13.4 (#2220, #2223)
Google api from 0.28.0 to 0.29.0 (#2193)

v1.3.10

Published 2020-07-02

Storage

The StorageProvider type and helpers have been moved from the server package to storage. Aliases for the old types/functions are created for backward compatibility, but the new code should not use them as we will remove them with the next major version bump. The individual storage providers have been moved to the corresponding packages, and are now required to be imported explicitly by the main file in order to be registered. We are including only MySQL and cloudspanner providers by default, since these are the ones that we support.

The cloudspanner storage is supported for logs only, while the Map storage API is being polished and decoupled from the log storage API. We may return the support when the new API is tested.

Support for storage of Ed25519 signatures has been added to the mysql and postgres storage drivers (only applicable in new installations) and bugs preventing correct usage of that algorithm have been fixed.

Storage TX Interfaces

QueueLeaves has been removed from the LogTreeTX interface because QueueLeaves is not transactional. All callers use the QueueLeaves function in the LogStorage interface.
AddSequencedLeaves has been removed from the LogTreeTX.

Log Changes

Monitoring & Metrics

The queued_leaves metric is removed, and replaced by added_leaves which covers both QueueLeaves and AddSequencedLeaves, and is labeled by log ID.

MySQL Dequeueing Change #2159

mysql will now remove leaves from the queue inside of UpdateLeaves rather than directly inside of Dequeue. This change brings the behavior of the mysql storage implementation into line with the spanner implementation and makes consistent testing possible.

Map Changes

The verifiable map is still experimental. APIs, such as SetLeaves, have been deprecated and will be deleted in the near future. The semantics of WriteLeaves have become stricter: now it always requires the caller to specify the write revision. These changes will not affect the Trillian module semantic version due to the experimental status of the Map.

Map API has been extended with Layout, GetTiles and SetTiles calls which allow for more direct processing of sparse Merkle tree tiles in the application layer. Map storage implementations are simpler, and no longer use the SubtreeCache.

The map client has been updated so that GetAndVerifyMapLeaves and GetAndVerifyMapLeavesByRevision return the MapRoot for the revision at which the leaves were fetched. Without this callers of GetAndVerifyMapLeaves in particular were unable to reason about which map revision they were seeing. The SetAndVerifyMapLeaves method was deleted.

v1.3.9

Published 2020-06-22

Selected Dependency Updates

etcd from v3.3.18 to 3.4.7 (#2090)
etcd-operator from v0.9.1 to v0.9.4
upgraded protoc version to latest (#2088)
github.com/golang/protobuf to v1.4.1 (#2111)
google.golang.org/grpc from v1.26 to 1.29.1 (#2108)

v1.3.8

Published 2020-05-12

HTTP APIs

The HTTP/JSON APIs have been removed in favor of a pure gRPC intereface. grpcurl is the recommended way of interacting with the gRPC API from the commandline.

v1.3.7

Published 2020-05-12

Server Binaries

The trillian_log_server, trillian_log_signer and trillian_map_server binaries have moved from github.com/google/trillian/server/ to github.com/google/trillian/cmd. A subset of the server package has also moved and has been split into cmd/internal/serverutil, quota/etcd and quota/mysqlqm packages.

v1.3.6

Published 2020-05-12

Deployments

The Kubernetes configs will now provision 5 nodes for Trillian's Etcd cluster, instead of 3 nodes. This makes the Etcd cluster more resilient to nodes becoming temporarily unavailable, such as during updates (it can now tolerate 2 nodes being unavailable, instead of just 1).

Monitoring & Metrics

A count of the total number of individual leaves the logserver attempts to fetch via the GetEntries.* API methods has been added.

v1.3.5

Published 2020-05-12

Log Changes

Potential sequencer hang fixed

A potential deadlock condition in the log sequencer when the process is attempting to exit has been addressed.

Quota

New Features

An experimental Redis-based quota.Manager implementation has been added.

Behaviour Changes

Quota used to be refunded for all failed requests. For uses of quota that were to protect against abuse or fair utilization, this could allow infinite QPS in situations that really should have the requests throttled. Refunds are now only performed for tokens in Global buckets, which prevents tokens being leaked if duplicate leaves are queued.

Tools

The licenses tool has been moved from "scripts/licenses" to a dedicated repository.

Bazel Changes

Python support is disabled unless we hear that the community cares about this being re-enabled. This was broken by a downstream change and without a signal from the Trillian community to say this is needed, the pragmatic action is to not spend time investigating this issue.

v1.3.4 - Invalid release, do not use.

Published 2020-05-12

v1.3.3 - Module fixes

Published 2019-10-31 17:30:00 +0000 UTC

Patch release to address Go Module issue. Removes replace directives in our go.mod file now that our dependencies have fixed their invalid pseudo-version issues.

v1.3.2 - Module fixes

Published 2019-09-05 17:30:00 +0000 UTC

Patch release to address Go Module issue. Some dependencies use invalid pseudo- versions in their go.mod files that Go 1.13 rejects. We've added replace directives to our go.mod file to fix these invalid pseudo-versions.

v1.3.1 - Module and Bazel fixes

Published 2019-08-16 15:00:00 +0000 UTC

Patch release primarily to address Go Module issue. v1.3.0 declared a dependency on github.com/russross/blackfriday/v2 v2.0.1+incompatible which made downstream dependencies suffer.

v1.3.0

Published 2019-07-17 15:00:00 +0000 UTC

Storage APIs GetSignedLogRoot / SetSignedLogRoot now take pointers

This at the storage layer and does not affect the log server API. This is part of work to fix proto buffer usages where they are passed by value or compared by generic code like reflect.DeepEquals(). Passing them by value creates shallow copies that can share internal state. As the generated structs contain additional exported XXX_ fields generic comparisons using all fields can produce incorrect results.

Storage Commit takes context.Context

To support passing a context down to NodeStorage.SetLeaves, and remove various context.TODO()s, the following functions have been modified to accept a context.Context parameter:

storage/cache.NodeStorage.SetLeaves
storage/cache.SetSubtreesFunc
storage/cache.SubtreeCache.Flush
storage.ReadonlyLogTX.Commit

Go Module Support

Go Module support has been enabled. Please use GO111MODULE=on to build Trillian. Updating dependencies no longer requires updating the vendor directory.

TrillianMapWrite API

New API service for writing to the Trillian Map. This allows APIs such as GetLeavesByRevisionNoProof to be removed from the read API, and these methods to be tuned & provisioned differently for read vs write performance.

GetLeavesByRevisionNoProof API

Allow map clients to forgo fetching inclusion proofs. This dramatically speeds things up for clients that don't need verifiability. This situation occurs in some situation where a Trillian personality is interacting directly with the Trillian Map.

GetMapLeafByRevision API

New GetMapLeafByRevision API for fetching a single map leaf. This allows there to be a separate API end point for fetching a single leaf vs. the batch GetMapLeavesByRevision API which is much slower when many leaves are requested. This supports separate monitoring and alerting for different traffic patterns.

Add Profiling Flags to Binaries

The trillian_log_server, trillian_log_signer and trillian_map_server binaries now have CPU and heap profiling flags. Profiling is off by default. For more details see the Go Blog.

Map performance tweaks

The map mode has had some performance tweaks added:

A workaround for locking issues which affect the map when it's used in single-transaction mode.

Introduce BatchInclusionProof function

Added a batch version of the Merkle Tree InclusionProof function.

Updated the map RPC for getLeaves to use the new batch function to improve efficiency.

Google Cloud Spanner support

Google Cloud Spanner is now a supported storage backend for maps.

The admin API calls to list trees backed by Cloud Spanner trees are fixed.

RPC Server Transaction Leaks Fixed

There were some cases where the Log RPC server could leak storage transactions in error situations. These have now been fixed. If you have a custom storage implementation review the fixes made to the MySQL Log storage to see if they need to be applied to your code (storage/mysql/log_storage.go). The Map server had similar issues but these were fixed without requiring changes to storage code.

GetLatestSignedLogRoot With Consistency Proof

GetLatestSignedLogRoot in the LogServer will return a consistency proof if first_tree_size > 0. This reduces the number of RPC calls from logClient from 2 to 1 in client.getAndVerifyLatestRoot.

Testing

Support has been added for testing against a locally running mysql docker image, in addition to a locally running mysql instance.

Deprecated Fields Removed From SignedLogRoot Proto

Important Note: For use in Certificate Transparency this version of the logserver binary won't work properly with an older CTFE. Make sure to update the CTFE servers to a current version (built from a git checkout after March 20th 2019) before deploying logservers that include this change or deploy them together with this release. Failure to do this can result in 5XX errors being returned to clients when the old handler code tries to access fields in responses that no longer exist.

All the fields marked as deprecated in this proto have been removed. All the same fields are available via the TLS marshalled log root in the proto. Updating affected code is straightforward.

Normally, clients will want to verify that the signed root is correctly signed. This is the preferred way to interact with the root data.

There is a utility function provided that will verify the signature and unpack the TLS data. It works well in conjunction with a LogVerifier. The public key of the server is required.

verifier := client.NewLogVerifier(rfc6962.DefaultHasher, pk, crypto.SHA256)
root, err := crypto.VerifySignedLogRoot(verifier.PubKey, verifier.SigHash, resp.SignedLogRoot)
if err != nil {
  // Signature verified and unmarshalled correctly. The struct may now
  // be used.
  if root.TreeSize > 0 {
    // Non empty tree.
  }
}

MySQL changes

Configurable number of connections for MySQL

Two new flags have been added that limit connections to MySQL database servers:

--mysql_max_conns - limits the total number of database connections
--mysql_max_idle_conns - limits the number of idle database connections

By default, there is no maximum number of database connections. However, the database server will likely impose limits on the number of connections. The default limit on idle connections is controlled by Go's sql package.

Enfored no concurrent use of MySQL tx

Concurrently using a single MySQL transaction can cause the driver to error out, so we now attempt to prevent this from happening.

Removal of length limits for a tree's `display_name` and `description`

Previously, these were restricted to 20 bytes and 200 bytes respectively. These limits have been removed. However, the underlying storage implementation may still impose its own limitations.

Server validation of leaf hashes

The log server now checks that leaf hashes are the correct length and returns an InvalidArgument error if they are not. Previously, GetLeavesByHash would simply not return any matching leaves for invalid hashes, and GetInclusionProofByHash would return a NotFound error.

Map client

A MapClient has been added to simplify interacting with the map server.

Database Schema

This version includes a change to the MySQL and Postgres database schemas to add an index on the SequencedLeafData table. This improves performance for inclusion proof queries.

Deployments

The Trillian Docker images now accept GOFLAGS and GO111MODULE arguments and set them as environment variables inside the Docker container.

The db_server Docker image is now based on the MySQL 5.7 image from the Google Cloud Marketplace, rather than the official MySQL 5.7 image. This Dockerfile supercedes Dockerfile.db, which has been removed.

There is now a mysql.cnf file alongside the Dockerfile that makes it easy to build the image with a custom configuration, e.g. to allow MySQL to use more memory.

The trillian-log-service and trillian-log-signer Kubernetes services will now have load balancers configured for them that expose those services outside of the Kubernetes cluster. This makes it easier to access their APIs. When deployed on Google Cloud, these will be Internal Load Balancers. Note that this change cannot be applied to an existing deployment; delete the existing Kubernetes services and redeploy them, otherwise you'll see an error similar to The Service "trillian-log-service" is invalid: spec.clusterIP: Invalid value: "": field is immutable.

A working Docker Compose configuration is now available and can be used to bring up a local Trillian deployment for testing and experimental purposes:

docker-compose -f examples/deployment/docker-compose.yml up

Docker Compose v3.1 or higher is required.

The Terraform, Kubernetes and Docker configuration files, as well as various scripts, all now use the same, consistently-named environment variables for MySQL-related data (e.g. MYSQL_DATABASE). The variable names are based on those for the MySQL Docker image.

Docker images have been upgraded from Go 1.9 to 1.11. They now use "Distroless" base images.

Dropped metrics

Quota metrics with specs of the form users/<user>/read and users/<user>/write are no longer exported by the Trillian binaries (as they lead to excessive storage requirements for Trillian metrics).

Resilience improvements in `log_signer`

Add timeout to sequencing loop

Added a timeout to the context in the sequencing loop, with a default of 60s.

Fix Operation Loop Hang

Resolved a bug that would hide errors and cause the OperationLoop to hang until process exit if any error occurred.

Linting toolchain migration

gometalinter has been replaced with golangci-lint for improved performance and Go module support.

Compact Merkle tree data structures

CompactMerkleTree has been removed from github.com/google/trillian/merkle, and a new package github.com/google/trillian/merkle/compact was introduced. A new powerful data structure named "compact range" has been added to that package, and is now used throughout the repository instead of the compact tree. It is a generalization of the previous structure, as it allows manipulating arbitrary sub-ranges of leaves rather than only prefixes.

Storage API changes

The internal storage API is modified so that the ReadOnlyTreeTX.ReadRevision and TreeWriter.WriteRevision entrypoints take a context.Context parameter and return an optional error.

The SubtreeCache.GetNodeHash() method is no longer exported.

The memory storage provider has been refactored to make it more consistent with the other storage providers.

The LogMetadata.GetUnsequencedCounts() method has been removed.

NodeReader.GetMerkleNodes now must return Node objects in the same order as node IDs requested. Storage implementations known to us already adhere to this requirement.

Maphammer improvements

The maphammer test tool for the experimental Trillian Map has been enhanced.

Default values changed for some signer flags

The following flags for the signer have new default values:

--sequencer_interval: changed from 10 seconds to 100 milliseconds
--batch_size: changed from 50 to 1000

These changes improve the signer's throughput and latency under typical conditions.

Master election refactoring

The --resign_odds flag in logsigner is removed, in favor of a more generic --master_hold_jitter flag. Operators using this flag are advised to set the jitter to master_check_interval * resign_odds * 2 to achieve similar behavior.

The --master_check_interval flag is removed from logsigner.

logsigner switched to using a new master election interface contained in util/election2 package. The interfaces in util/election are removed.

`CONIKS_SHA256` hash strategy added

Support has been added for a CONIKS sparse tree hasher with SHA256 as the hash algorithm. Set a tree's hash_strategy to CONIKS_SHA256 to use it.

Performance

The performance of SetLeaves requests on the Map has been slightly improved. The performance of GetConsistencyProof requests has been improved when using MySQL.

Logging

Some warning-level logging has been removed from the sequencer in favour of returning the same information via the returned error. The caller may still choose to log this information. This allows storage implementations that retry transactions to suppress warnings when a transaction initially fails but a retry succeeds.

Some incorrectly-formatted log messages have been fixed.

Documentation

API documentation in Markdown format is now available.

Other

The TimeSource type (and other time utils) moved to a separate util/clock package, extended with a new Timer interface that allows mocking time.Timer.

The Sequencer.SignRoot() method has been removed.

v1.2.1 - Map race fixed. TLS client support. LogClient improvements

Published 2018-08-20 10:31:00 +0000 UTC

Servers

A race condition was fixed that affected sparse Merkle trees as served by the map server.

Utilities / Binaries

The maphammer uses a consistent empty check, fixing spurious failures in some tests.

The createtree etc. set of utilities now support TLS via the -tls-cert-file flag. This support is also available as a client module.

Log Client

GetAndVerifyInclusionAtIndex no longer updates the clients root on every access as this was an unexpected side effect. Clients now have explicit control of when the root is updated by calling UpdateRoot.

A root parameter is now required when log clients are constructed.

The client will now only retry requests that fail with the following errors:

Aborted
DeadlineExceeded
ResourceExhausted
Unavailable

There is one exception - it will also retry InitLog/InitMap requests that fail due to a FailedPrecondition error.

Other

The Travis build script has been updated for newer versions of MySQL (5.7 through MySQL 8) and will no longer work with 5.6.

v1.2.0 - Signer / Quota fixes. Error mapping fix. K8 improvements

Published 2018-06-25 10:42:52 +0000 UTC

The Log Signer now tries to avoid creating roots older than ones that already exist. This issue has been seen occurring on a test system. Important note: If running this code in production allowing clocks to drift out of sync between nodes can cause other problems including for clustering and database replication.

The Log Signer now publishes metrics for the logs that it is actively signing. In a clustered environment responsibility can be expected to move around between signer instances over time.

The Log API now allows personalities to explicitly list a vector of identifiers which should be charged for User quota. This allows a more nuanced application of request rate limiting across multiple dimensions. Some fixes have also been made to quota handling e.g. batch requests were not reserving the appropriate quota. Consult the corresponding PRs for more details.

For the log RPC server APIs GetLeavesByIndex and GetLeavesByRange MySQL storage has been modified to return status codes that match CloudSpanner. Previously some requests with out of range parameters were receiving 5xx error status rather than 4xx when errors were mapped to the HTTP space by CTFE.

The Kubernetes deployment scripts continue to evolve and improve.

v1.1.1 - CloudSpanner / Tracing / Health Checks

Published 2018-05-08 12:55:34 +0000 UTC

More improvements have been made to the CloudSpanner storage code. CloudSpanner storage has now been tested up to ~3.1 billion log entries.

Explicit health checks have been added to the gRPC Log and Map servers (and the log signer). The HTTP endpoint must be enabled and the checks will serve on /healthz where a non 200 response means the server is unhealthy. The example Kubernetes deployment configuration has been updated to include them. Other improvements have been made to the Kubernetes deployment scripts and docs.

The gRPC Log and Map servers have been instrumented for tracing with OpenCensus. For GCP it just requires the --tracing flag to be added and results will be available in the GCP console under StackDriver -> Trace.

v1.1.0 - CloudSpanner Improvements & Log Root structure changes etc.

Published 2018-04-17 08:02:50 +0000 UTC

Changes are in progress (e.g. see #1037) to rework the internal signed root format used by the log RPC server to be more useful / interoperable. Currently they are mostly internal API changes to the log and map servers. However, the signature and log_id fields in SignedLogRoot have been deleted and users must unpack the serialized structure to access these now. This change is not backwards compatible.

Changes have been made to log server APIs and CT frontends for when a request hits a server that has an earlier version of the tree than is needed to satisfy the request. In these cases the log server used to return an error but now returns an empty proof along with the current STH it has available. This allows clients to detect these cases and handle them appropriately.

The CloudSpanner schema has changed. If you have a database instance you'll need to recreate it with the new schema. Performance has been noticeably improved since the previous release and we have tested it to approx one billion log entries. Note: This code is still being developed and further changes are possible.

Support for sqlite in unit tests has been removed because of ongoing issues with flaky tests. These were caused by concurrent accesses to the same database, which it doesn't support. The use of sqlite in production has never been supported and it should not be used for this.

v1.0.8 - Docker Updates / Freezing Logs / CloudSpanner Options

Published 2018-03-08 13:42:11 +0000 UTC

The Docker image files have been updated and the database has been changed to MariaDB 10.1.

A ReadOnlyStaleness option has been added to the experimental CloudSpanner storage. This allows for tuning that might increase performance in some scenarios by issuing read transactions with the exact_staleness option set rather than strong_read. For more details see the CloudSpanner TransactionOptions documentation.

The LogVerifier interface has been removed from the log client, though the functionality is still available. It is unlikely that there were implementations by third-parties.

A new TreeState DRAINING has been added for trees with TreeType LOG. This is to support logs being cleanly frozen. A log tree in this state will not accept new entries via QueueLeaves but will continue to integrate any that were previously queued. When the queue of pending entries has been emptied the tree can be set to the FROZEN state safely. For MySQL storage this requires a schema update to add 'DRAINING' to the enum of valid states.

A command line utility updatetree has been added to allow tree states to be changed. This is also to support cleanly freezing logs.

A 'howto' document has been added that explains how to freeze a log tree using the features added in this release.

v1.0.7 - Storage API Changes, Schema Tweaks

Published 2018-03-01 11:16:32 +0000 UTC

Note: A large number of storage related API changes have been made in this release. These will probably only affect developers writing their own storage implementations.

A new tree type ORDERED_LOG has been added for upcoming mirror support. This requires a schema change before it can be used. This change can be made when convenient and can be deferred until the functionality is available and needed. The definition of the TreeType column enum should be changed to ENUM('LOG', 'MAP', 'PREORDERED_LOG') NOT NULL

Some storage interfaces were removed in #977 as they only had one implementation. We think this won't cause any impact on third parties and are willing to reconsider this change if it does.

The gRPC Log and Map server APIs have new methods InitLog and InitMap which prepare newly created trees for use. Attempting to use trees that have not been initialized will return the FAILED_PRECONDITION error storage.ErrTreeNeedsInit.

The gRPC Log server API has new methods AddSequencedLeaf and AddSequencedLeaves. These are intended to support mirroring applications and are not yet implemented.

Storage APIs have been added such as ReadWriteTransaction which allows the underlying storage to manage the transaction and optionally retry until success or timeout. This is a more natural fit for some types of storage API such as CloudSpanner and possibly other environments with managed transactions.

The older BeginXXX methods were removed from the APIs. It should be fairly easy to convert a custom storage implementation to the new API format as can be seen from the changes made to the MySQL storage.

The GetOpts options are no longer used by storage. This fixed the strange situation of storage code having to pass manufactured dummy instances to GetTree, which was being called in all the layers involved in request processing. Various internal APIs were modified to take a *trillian.Tree instead of an int64.

A new storage implementation has been added for CloudSpanner. This is currently experimental and does not yet support Map trees. We have also added Docker examples for running Trillian in Google Cloud with CloudSpanner.

The maximum size of a VARBINARY column in MySQL is too small to properly support Map storage. The type has been changed in the schema to MEDIUMBLOB. This can be done in place with an ALTER TABLE command but this could very be slow for large databases as it is a change to the physical row layout. Note: There is no need to make this change to the database if you are only using it for Log storage e.g. for Certificate Transparency servers.

The obsolete programs queue_leaves and fetch_leaves have been deleted.

v1.0.6 - GetLeavesByRange. 403 Permission Errors. Signer Metrics.

Published 2018-02-05 16:00:26 +0000 UTC

A new log server RPC API has been added to get leaves in a range. This is a more natural fit for CT type applications as it more closely follows the CT HTTP API.

The server now returns 403 for permission denied where it used to return 500 errors. This follows the behaviour of the C++ implementation.

The log signer binary now reports metrics for the number it has signed and the number of errors that have occurred. This is intended to give more insight into the state of the queue and integration processing.

v1.0.5 - TLS, Merge Delay Metrics, Easier Admin Tests

Published 2018-02-07 09:41:08 +0000 UTC

The API protos have been rebuilt with gRPC 1.3.

Timestamps have been added to the log leaves in the MySQL database. Before upgrading to this version you must make the following schema changes:

Add the following column to the LeafData table. If you have existing data in the queue you might have to remove the NOT NULL clause: QueueTimestampNanos BIGINT NOT NULL
Add the following column to the SequencedLeafData table: IntegrateTimestampNanos BIGINT NOT NULL

The above timestamps are used to export metrics via monitoring that give the merge delay for each tree that is in use. This is a good metric to use for alerting on.

The Log and Map RPC servers now support TLS.

AdminServer tests have been improved.

v1.0.4 - Fix election issue. Large vendor updates.

Published 2018-02-05 15:42:25 +0000 UTC

An issue has been fixed where the master for a log could resign from the election while it was in the process of integrating a batch of leaves. We do not believe this could cause any issues with data integrity because of the versioned tree storage.

This release includes a large number of vendor commits merged to catch up with etcd 3.2.10 and gRPC v1.3.

v1.0.3 - Auth API. Interceptor fixes. Request validation + More

Published 2018-02-05 15:33:08 +0000 UTC

An authorization API has been added to the interceptors. This is intended for future development and integration.

Issues where the interceptor would not time out on PutTokens have been fixed. This should make the quota system more robust.

A bug has been fixed where the interceptor did not pass the context deadline through to other requests it made. This would cause some failing requests to do so after longer than the deadline with a misleading reason in the log. It did not cause request failures if they would otherwise succeed.

Metalinter has been added and the code has been cleaned up where appropriate.

Docker and Kubernetes scripts have been available and images are now built with Go 1.9.

Sqlite has been introduced for unit tests where possible. Note that it is not multi threaded and cannot support all our testing scenarios. We still require MySQL for integration tests. Please note that Sqlite must not be used for production deployments as RPC servers are multi threaded database clients.

The Log RPC server now applies tighter validation to request parameters than before. It's possible that some requests will be rejected. This should not affect valid requests.

The admin server will only create trees for the log type it is hosted in. For example the admin server running in the Log server will not create Map trees. This may be reviewed in future as applications can legitimately use both tree types.

v1.0.2 - TreeGC, Go 1.9, Update Private Keys.

Published 2018-02-05 15:18:40 +0000 UTC

Go 1.9 is required.

It is now possible to update private keys via the admin API and this was added to the available field masks. The key storage format has not changed so we believe this change is transparent.

Deleted trees are now garbage collected after an interval. This hard deletes them and they cannot be recovered. Be aware of this before upgrading if you have any that are in a soft deleted state.

The Admin RPC API has been extended to allow trees to be undeleted - up to the point where they are hard deleted as set out above.

v1.0.1 - Batched Queue Option Added

Published 2018-02-05 14:49:33 +0000 UTC

Apart from fixes this release includes the option for a batched queue. This has been reported to allow faster sequencing but is not enabled by default.

If you want to switch to this you must build the code with the --tags batched_queue option. You must then also apply a schema change if you are running with a previous version of the database. Add the following column to the Unsequenced table:

QueueID VARBINARY(32) DEFAULT NULL

If you don't plan to switch to the batched_queue mode then you don't need to make the above change.

v1.0 - First Log version we believe was ready for use. To support CT.

Published 2018-02-05 13:51:55 +0000 UTC

Quota metrics published. Quota admin api + server implemented. Improvements to local / AWS deployment. Map fixes and further development. ECDSA key handling improvements. Key factory improvements. Code coverage added. Quota integration test added. Etcd quota support in log and map connected up. Incompatibility with C++ code fixed where consistency proof requests for first == second == 0 were rejected.
