Changelog

DittoSwift Version 4.8.1-rc.1

Released: Wed Aug 28th 2024, 3:34 pm

Release Notes:

  • Fixed: A rare scenario where attachments may not be transferred between two peers. (#14158)
  • Other: When failing to load document replication metadata, Ditto now attempts to clear and regenerate the metadata instead of failing to start. This primarily serves to prevent problems after SDK version downgrades. (#13111)
  • Fixed: On-disk logs are now more robust to unclean Ditto shutdown. (#13723)
  • Added: The presence_use_multihop system parameter can be used to disable replicating presence information to other peers in the mesh, reducing network overhead. (#14128)
  • Fixed: iOS devices may fail to sync on LAN when the app is backgrounded then foregrounded. (#14150)
  • Fixed: AWDL may sometimes create spurious advertisements when app is backgrounded and foregrounded, affecting mesh connectivity (#14151)

  • Changed: TransportConfig and its associated types can be serialized/deserialized into/from JSON and CBOR. (#9585)
  • Changed: Sets a minimum session refresh period. The small peer will always try to start refreshing its session after 3 days no matter how long the session period issue. Previously the small peer would start to refresh after half of the session length had elapsed. (#9594, #9645)
  • Improved: Initial replication time by reducing one roundtrip of messages before peers can sync. (#9404)
  • Improved: Attachment fetch time in several edge case scenarios. (#9501)

DittoSwift Version 4.3.0

Released: Wed Jul 19th 2023, 5:02 am

Release Notes:

⚠️ Warning: This SDK version will migrate some data formats on disk. Once upgraded to 4.3.0, an SDK can only be downgraded back to 4.2.2 and 4.2.1 but no earlier. Downgrading to versions earlier than 4.2.1 will require uninstalling and re-installing to clear out the new data formats. (#8946)

  • Added: Optional customAuthURL parameter to the DittoIdentity.onlinePlayground enum case. (#9131)
  • Added: An internal ability to measure & report the level of redundancy in replication updates to calculate the percentage of updates that are arriving from multiple peers. This will be used for future self-balancing mesh actions which are not yet enabled. (#8937)
  • Changed: new serialization format improves efficiency of replication, particularly in the Big Peer. (#8946)
  • Changed: Better logging for diagnosing auth failures. (#8984)
  • Changed: Improved replication performance by introducing a small internal caching layer for commonly computed values. (#8777)
  • Fixed: The replication engine can now recover from certain filesystem corruption issues during sync instead of panicking. (#8965)

DittoSwift Version 4.1.0

Released: Fri Apr 28th 2023, 6:52 pm

Release Notes:

  • Added: Disabled replication state. When the Big Peer receives a query that is too big to be satisfied, it will explicitly disable replication with the remote peer, and send a message informing the remote peer that replication is disabled. This is in contrast to the previous behavior, where the Big Peer simply did not respond to the query.
  • Changed: now including NSNetServicesErrorCode and Domain in AWDL connect log messages
  • Changed: Ditto instances cannot be closed/deallocated from within a live query callback closure otherwise this can lead to a deadlock.
  • Changed: (Experimental) Query Overlap Groups, Bus: a breaking protocol change for upcoming improvements. Peers using older versions will not be able to connect with newer peers until they upgrade.
  • Fixed: A replication issue where certain cases that should have reset the replication session with a remote peer would instead temporarily terminate the connection while not resetting the session.
  • Fixed: A replication issue that could cause failed convergence on small number of documents if updates are being received during a local eviction.
  • Security: Enforce immediate disconnection of any connected peers whose certificate expires during a sync session.

  • Changed: If a problem occurs with an app's authentication webhook, the Small Peer that is trying to authenticate will log more detailed information for the developer.
  • Changed: old multi-hop connections are now automatically disconnected when direct connections are established with peers, freeing up unneeded resources faster.
  • Changed: reduced severity level for some routine log statements which were previously emitted at a WARN level.
  • Fixed: some threads spawned by the SDK no longer wait up to 30 seconds before being stopped.
  • Fixed: an issue which could cause Ditto to hang if more than 500 peers were encountered.
  • Fixed: replication hanging under some circumstances, especially WebSocket connections to Big Peer
  • Fixed: a possible crash if Ditto is configured with an invalid App ID. An error message is emitted instead.
  • Fixed: an issue preventing clean Ditto shutdown.
  • Fixed: cancelling subscriptions for queries with args would not work, the subscription would remain active indefinitely.
  • Fixed: some memory leaks.

DittoSwift Version 4.0.0-alpha2

Released: Mon Jan 16th 2023, 10:16 pm

Release Notes:

  • Added: disableSyncWithV3 functionality to Ditto. Calling this will permanently remove the ability for the device that it is called on to sync with devices running v3 of the SDK. It also means that the device will then start performing AddWins removes when calling remove(). Any other device running v4 of the SDK that syncs with a device that has called disableSyncWithV3 (or has themselves synced with another device that has called disableSyncWithV3, etc - if any chain of syncing exists that involves a device that has called disableSyncWithV3) will also no longer be able to sync with v3 peers and will perform AddWins removes when calling remove().

  • Deprecated: methods observePeers() and observePeersV2() of Ditto, please use observe() of DittoPresence instead (accessible via newly introduced presence property of Ditto).
  • Deprecated: DITRemotePeer, replaced by DITPeer.
  • Deprecated: DITPeersObserver, replaced by DITObserver protocol.
  • Deprecated: DITPeersObserverV2, replaced by DITObserver protocol.

  • Removed: all persistenceDirectory arguments from all of the identity type constructors.
  • Changed: performance improvements.
  • Added: disableSyncWithV2 method to Ditto. This allows you to explicitly opt-in to disabling the ability to sync with Ditto peers running any version of the SDK in the v2 series of releases. Assuming this succeeds then this peer will only be able to sync with other peers using SDKs in the v3 series of releases. Note that this disabling of sync spreads to peers that sync with a peer that has disabled, or has (transitively) had disabled, syncing with v2 SDK peers.
  • Improved: reliability if app crashes occur while persisting authentication data.
  • Added: statusPublisher() method to DittoAuthenticator.
  • Added: DittoAuthenticator.StatusPublisher, a Combine publisher for DittoAuthenticationStatus change events.
  • Improved: log increased detail to help debug blocked write transactions.

DittoSwift Version 2.0.0

Released: Wed Aug 3rd 2022, 2:54 pm

Release Notes:

  • Note: peers running 2.0.0 are able to sync with peers running at least version 1.1.8 of the SDK.
  • Added: support for explicitly typing values as registers. This is via 2 new types: DittoRegister and DittoMutableRegister, and new registerValue value accessors added to DittoDocumentPath and DittoMutableDocumentPath.
  • Added: DittoCounter and DittoMutableCounter types resembling the CRDT type underneath, which replace the old counter mechanics. A new counter value accessor has been added to DittoDocumentPath and DittoMutableDocumentPath, which returns a DittoCounter or a DittoMutableCounter respectively, if one is present at the document path specified.
  • Added: support for accessing and creating RGAs (Replicated Growable Arrays), which was the default CRDT type for arrays in Ditto v1. There are 2 new types: DittoRGA and DittoMutableRGA in v2, and new rga value accessors added to DittoDocumentPath and DittoMutableDocumentPath. Note that these are deprecated though and arrays should instead be used in registers (which is now the default).
  • Changed: arrays now default to being Register arrays. This means that when you want to update a property in a document that's an array you need to set the whole value as the new array. You can't perform mutating operations on an array in a document other than to fully replace it.
  • Added: value accessor properties have been added to DittoDocumentID: value, string{Value}, bool{Value}, int{Value}, uint{Value}, float{Value}, double{Value}, array{Value}, dictionary{Value}.
  • Changed: the keys DittoAccessLicense and DittoLicenseToken in Info.plist will now fail with a fatal error instead of logging a deprecation warning. Please use the key DittoOfflineOnlyLicenseToken instead.
  • Changed: renamed identity onlinePlaygroundV2 to just onlinePlayground, which replaces the previously deprecated onlinePlayground.
  • Changed: renamed Ditto method tryStartSync() to just startSync(), which replaces the previously deprecated startSync().
  • Removed: deprecated DittoRemotePeerV2 property meshRole, please queryOverlapGroup instead.
  • Removed: deprecated type DittoPeersObserver, please use DittoObserver instead.
  • Removed: deprecated DittoDocumentID method toNative(), please use property value instead.
  • Removed: deprecated DittoScopedWriteTransaction method find(query:), please use find() instead.
  • Removed: deprecated DittoScopedWriteTransaction methods insert() and insertWithStrategy(), please use upsert() and upsertWithStrategy() instead.
  • Removed: deprecated DittoCollection methods insert() and insertWithStrategy(), please use upsert() and upsertWithStrategy() instead.
  • Removed: deprecated identities development and online, please use the available ones instead.
  • Removed: deprecated Ditto methods setAccessLicense() and setLicenseToken(), please use setOfflineOnlyLicenseToken() instead.
  • Removed: deprecated Ditto method setTransportConfig(), please set the transportConfig property directly.
  • Removed: deprecated DittoAuthenticator method isAuthenticated() and property userID, please use status instead.
  • Removed: DittoWriteStrategy.overwrite.

DittoSwift Version 1.0.18-alpha1

Released: Wed Dec 8th 2021, 5:25 pm

Release Notes:

  • Fixed an issue where document IDs that were specified inside the document's value as opposed to being specified explicitly (as a separate argument to insert) weren't being processed correctly, potentially leading to bugs with merge and overwrite behaviors.
  • macOS (including Apple Silicon) and iOS simulator (on an Apple Silicon device) support has been added.

DittoSwift Version 1.0.16

Released: Fri Nov 19th 2021, 10:39 pm

Release Notes:

  • Fix an issue with live queries that involved a limit, no offset, at least one document being deleted, and some other conditions being met. Live queries that met these conditions could report incorrect sets of matching documents.
  • Fix an issue that could potentially lead to an infinite loop in the replication system, meaning no sync progress would be made.

Installation: 

pod 'DittoSwift', '=1.0.16'
API Reference URL

DittoSwift Version 1.0.15

Released: Fri Nov 5th 2021, 10:03 pm

Release Notes:

  • Ensure that when performing a sort that if a document that matches the filter specified via the accompanying find call doesn't have the key specified in the sort expression then it won't lead to an error. Now, if you're sorting in a descending order then the documents without the key specified in the sort will appear at the end of the set of results, after all of the documents that do have the key present. If you're sorting in an ascending order then the documents without the sort key will appear first in the set of documents, before all of the documents that do contain the sort key.
  • Fixed handling of large integers in documents. Integers larger than Int.max were still trying to be handled as Ints, leading to crashes. We now correctly handle them as UInts when appropriate.
  • Add the ability to directly set values inside the closure passed to an update call with assignments done via = sets, e.g. collection.findByID("123").update { $0!["color"] = "white" }
  • Fix a bug where some transports related calls were not being run on the correct thread and so could lead to a crash.

Installation: 

pod 'DittoSwift', '=1.0.15'

DittoSwift Version 1.0.15-alpha1

Released: Wed Oct 27th 2021, 10:33 am

  • Fixed AWDL peers never re-connecting after transport is toggled.
  • Fixed mDNS transport crash.
  • Fixed sporadic hangs and crashes when using Online identity.
  • Added isAuthenticated() method and userID property to DittoAuthenticator.
  • Fixed Codable support for non-string IDs and Float and Double types.

Released: Fri Sep 10th 2021, 4:21 pm

Release Notes:

  • Fix to stop a change in site ID from leading to an unnecessary error.
  • Improve handling of persisted authentication data. Note that this might lead to a one-off change to a peer's site ID if you weren't and continue to not be specifying an explicit site ID when creating your identity.

Installation: 

pod 'DittoSwift', '=1.0.10'
API Reference URL

DittoSwift Version 1.0.9

Released: Fri Sep 3rd 2021, 10:38 pm

Release Notes:

  • Added support for getting information about all of the collections that the device is aware of. This is achieved by accessing collections() through the store object and then using the same sort of API used when getting documents in collections, i.e. exec/observe/etc.
  • Added multicast as a transport option to the LAN config part of TransportConfig.
  • Added new identity types: Online and OnlinePlayground. An Online identity should be used when running Ditto in secure production mode, logging on to Ditto Cloud, or using an on-premises authentication server. User permissions are centrally managed. Sync will not work until a successful login has occurred. An OnlinePlayground identity should be used when you want to test a Ditto Cloud app without authentication ("Playground mode"). This mode offers no security and must only be used for development.
  • The Production identity has been renamed to Manual.
  • Added a DittoAuthenticator type, accessible via the Ditto object, which allows you to perform login operations when you're using an Online identity.
  • Similarly, added an DittoAuthenticationDelegate type that needs to be used when using an Online identity.
  • Report an error if more than one Ditto instance is started using the same working directory.

Installation: 

pod 'DittoSwift', '=1.0.6'
API Reference URL

DittoSwift Version 1.0.5

Released: Fri Jun 25th 2021, 10:36 pm

Release Notes:

  • Added a new find function that accepts a query containing placeholders in the form of $args.my_arg along with a map of query arguments in the form of { "my_arg": "some value" }. The placeholders in the query will be replaced by a query-appropriate representation of the relevant value from the map of query arguments.

    For example, a query of color == $args.color with a query arguments map of { "color": "red" } would internally be treated as a query of: color == "red".

  • Added the ability to get a hash and/or a mnemonic (string) representation of the matching documents from a live query event. This means you can do something like this:

    let liveQuery = collection.findAll().observe() { docs, event in
    event.hash(docs); // e.g. `1950015808188223905`
    event.hashMnemonic(docs); // e.g. `locate-quality-tina--helena-remote-cat`
    // ...
}

  • Fix for using floats in queries.

  • Accessing the store property of a Ditto instance will no longer throw an error if you have not yet activated your Ditto instance with a valid license token.

  • Deprecated setAccessLicense and added a new function, setLicenseToken, which will throw an appropriate error if your provided license token is expired or invalid somehow.

  • Deprecated startSync and added a new function, tryStartSync, which will throw an error if your Ditto instance hasn't yet been activated via a successful call to setLicenseToken.

DittoSwift Version 1.0.0

Released: Thu Apr 22nd 2021, 12:29 am

Release Notes:

  • This release is not compatible with any previous SDK releases. There are a number of breaking changes both in terms of the SDK API and in terms of the internal systems used by the SDK to perform operations such as synchronization. If you have previously made use of the Ditto SDK and wish to update to this version then note that you will need to delete all existing Ditto data otherwise you will run into errors. If you have existing data that you need to keep then please contact us and we can advise you as to how you can migrate your data.
  • The most notable API breaking changes are:
    • Document IDs are no longer restricted to just strings. You can now create a document ID that is a string, integer, boolean, array, map, or null. This means that when making findByID or insert calls you now need to provide a DittoDocumentID object rather than a string. Similarly, when you access a document's ID it will now return a DittoDocumentID object instead of a string.
    • The start() and stop() functions on the Ditto object have been renamed to startSync() and stopSync() respectively. They now also don't accept any arguments. If you wish to specify which transports you would like the Ditto SDK to make use of (along with any configuration that they might require) you now need to use the setTransportConfig function on the Ditto object, and pass to that a transport config object. The default transports that will be enabled are still the same as they were in previous releases of the SDK though, so if you have no custom requirements then you can simply change your start() call to startSync().
  • Lots of performance improvements and bug fixes.
