brick_offline_first 3.1.0

A Brick domain that routes data fetching through local providers before remote providers.

Unreleased

3.1.0

• Apply standardized lints
• Respect awaitRemote policy for OfflineFirstRepository#get - fixes a bug where an instance in memory cache would early-return before hitting remote despite the requested await or alwaysHydrate policy

3.0.3

• Support Dart 3

3.0.2

• Permit awaiting remote on first get in OfflineFirstRepository#subscribe. While the default for the policy argument of this method has changed, it was unapplied (.localOnly was used regardless).

3.0.1

• Resolve concurrent modification error when looping through subscriptions

3.0.0

• Remove brick_sqlite_abstract
• Remove brick_offline_first_abstract
• Add OfflineFirstRepository#subscribe. The query provided when invoked is stored on the repository. Whenever data is locally mutated with storeRemoteResults or upsert or delete that matches one of these stored queries, the stream receives the latest data for the query. It is strongly recommended to store the subscription after creating the stream and listening to it; cancelling the stream will close it and remove the stream to prevent memory leaks.
• Add fieldsToOfflineFirstRuntimeDefinition to OfflineFirstAdapter. This exposes @OfflineFirst(where configuration to repositories
• Add applyToRemoteDeserialization to @OfflineFirst. When true (the default and existing behavior), deserializing methods will query based on where configuration

2.1.2

• Set default of 5 seconds for RequestSqliteCacheManager#processingInterval

2.1.1

• Include type argument on _upsertLocal within #upsert

2.1.0

• Loosen dependency restrictions to major versions
• Remove Flutter dependency by upgrading brick_sqlite

2.0.0

• BREAKING CHANGE requireRemote has been removed from get() and getBatched(). Instead, use policy: OfflineFirstGetPolicy.alwaysHydrate
• BREAKING CHANGE hydrateUnexisting has been removed from get(). Instead, use policy: OfflineFirstGetPolicy.awaitRemoteWhenNoneExist (this is the default).
• BREAKING CHANGE alwaysHydrate has been removed from get(). Instead, use policy: OfflineFirstGetPolicy.alwaysHydrate.
• BREAKING CHANGE This package no longer includes the OfflineFirstWithRest domain. Please add brick_offline_first_with_rest: any to your pubspec.yaml and update package imports appropriately.
• Use forked brick_offline_first_with_PROVIDER_abstract packages
• BREAKING CHANGE rest properties have been removed from OfflineFirstException. Use OfflineFirstWithRestException instead from brick_offline_first_with_rest.
• Add GraphqlOfflineRequestQueue to support offline caching within the GraphqlProvider
• Add applyPolicyToQuery to OfflineFirstRepository to add the policy before requests are made to remote providers.
• Add OfflineFirstDeletePolicy, OfflineFirstGetPolicy, and OfflineFirstUpsertPolicy to override default behavior
• delete now supports requiring a successful remote with OfflineFirstDeletePolicy.requireRemote. If the app is offline, normally handled exceptions (ClientException and SocketException) are rethrown. (#182)
• upsert now supports requiring a successful remote with OfflineFirstUpsertPolicy.requireRemote. If the app is offline, normally handled exceptions (ClientException and SocketException) are rethrown.
• Rename RequestSqliteCacheManager to RestRequestSqliteCacheManager
• Rename OfflineQueueHttpClient to RestOfflineQueueClient
• Rename OfflineRequestQueue to RestOfflineRequestQueue

2.0.0-rc.4

• Add applyPolicyToQuery to OfflineFirstRepository to add the policy before requests are made to remote providers.

2.0.0-rc.3

• Add OfflineFirstDeletePolicy, OfflineFirstGetPolicy, and OfflineFirstUpsertPolicy to override default behavior
• delete now supports requiring a successful remote with OfflineFirstDeletePolicy.requireRemote. If the app is offline, normally handled exceptions (ClientException and SocketException) are rethrown. (#182)
• upsert now supports requiring a successful remote with OfflineFirstUpsertPolicy.requireRemote. If the app is offline, normally handled exceptions (ClientException and SocketException) are rethrown.
• BREAKING CHANGE requireRemote has been removed from get() and getBatched(). Instead, use policy: OfflineFirstGetPolicy.alwaysHydrate
• BREAKING CHANGE hydrateUnexisting has been removed from get(). Instead, use policy: OfflineFirstGetPolicy.awaitRemoteWhenNoneExist (this is the default).
• BREAKING CHANGE alwaysHydrate has been removed from get(). Instead, use policy: OfflineFirstGetPolicy.alwaysHydrate.

2.0.0-rc.2

• BREAKING CHANGE This package no longer includes the OfflineFirstWithRest domain. Please add brick_offline_first_with_rest: any to your pubspec.yaml and update package imports appropriately.
• Use forked brick_offline_first_with_PROVIDER_abstract packages
• BREAKING CHANGE rest properties have been removed from OfflineFirstException. Use OfflineFirstWithRestException instead from brick_offline_first_with_rest.

2.0.0-rc.1

• Add GraphqlOfflineRequestQueue to support offline caching within the GraphqlProvider
• Rename RequestSqliteCacheManager to RestRequestSqliteCacheManager
• Rename OfflineQueueHttpClient to RestOfflineQueueClient
• Rename OfflineRequestQueue to RestOfflineRequestQueue

1.1.0

• Carry providerArgs from query when using getBatched (#200)
• Add Flutter Lints

1.0.0

• Null safety
• Priority for the next job to process from the queue - when processing requests in serial - has changed from '$HTTP_JOBS_CREATED_AT_COLUMN ASC, $HTTP_JOBS_ATTEMPTS_COLUMN DESC, $HTTP_JOBS_UPDATED_AT ASC' to '$HTTP_JOBS_CREATED_AT_COLUMN ASC'; this uses the job column introduced in 0.0.7 (26 May 2020) and will not affect any implementations using 0.0.7 or higher.
• RequestSqliteCache no longer queries cached requests based on headers; requests are rediscovered based on their encoding, URL, request method, and body. Rehydrated (reattempted) requests will be hydrated with headers from the original request.
• BREAKING CHANGE Field types in models Set<Future<OfflineFirstModel>>, List<Future<OfflineFirstModel>>, and Future<OfflineFirstModel> are no longer supported. Instead, use Set<OfflineFirstModel>, List<OfflineFirstModel>, and OfflineFirstModel (the adapters will await each).
• BREAKING CHANGE StubOfflineFirstWithRest is functionally changed. SQLiteFFI has satisfied much of the original stubbing required for this class, and http's testing.dart library is sufficient to not require Mockito. Therefore, verify calls will no longer be effective in testing on the client. Instead, pass StubOfflineFirstWithRest.client to your RestProvider#client with the response values. StubOfflineFirstWithRestModel has been removed. Please review Offline First Testing for implementation examples.
• Do not reprocess queue requests during a single attempt. Server response times may be greater than the reattempt timer; in these situations, requests should remain locked.
• Introduce mutex around processing in the OfflineRequestQueue. This will avoid simultaneous DB writes on different isolates* while a previous operation is still performing.

*Or sub routines? Microtasks? It's unclear how Timer moves its work to the background or how to force it to remain in the original "thread."

0.1.2

• Add mixins.dart for non essential but still regularly requested features that depend on a specific format of remote data or are useful variations of existing features. DeleteAllMixin and DestructiveLocalSyncFromRemoteMixin are the first two such mixins.
• Expose RequestSqliteCache#findRequestInDatabase for subclass methods. (#111)

0.1.1

• Gracefully handle SocketException errors when the application is offline
• Call exists in OfflineFirstRepository#get after the memory provider has already been queried. This method can query the SqliteProvider which is an unnecessary database call when the model exists in the memory provider.
• RequestSqliteCacheManager: access SQLite db safely to avoid race conditions
• RequestSqliteCacheManager: refactor database path. This does not change the database's existing path as the use of getDatabasesPath() in the implementation was duplicating default functionality

0.1.0

• BREAKING CHANGE One-to-many and many-to-many SQLite associations are no longer stored as JSON-encoded strings (i.e. [1, 2, 3] in a varchar column). Join tables are now generated by Brick. To convert existing data, please refer to the brick_sqlite CHANGELOG notes. If you do not care about existing migration and have not widely distributed your app, simply delete all existing migrations, delete all existing app installs, and run flutter pub run build_runner build in your project root.
• Fixes undefined method when calling hydrate offline. The remote provider would return null, and SQLite/memory cache would not adequately store results. Instead, when a null response is returned from the remote provider, subsequent provider updates are skipped.
• Adds a configurable option to throw on status codes that are normally swallowed in OfflineFirstWithRest#upsert (such as 404, 50x).

0.0.7

• Add reattemptForStatusCode for OfflineFirstWithRestRepository#upsert requests. When the response matches a reattempt code, an exception is not thrown and the instance is returned instead.
• Add 501 to OfflineQueueHttpClient#reattemptForStatusCode defaults
• Insert a created_at column for the OfflineRequestQueue.
• Fix a bug where an HTTP request would be immediately duplicated. In some race conditions, the interval timer would immediately recreate the request after it was inserted and before the HTTP response was received.
• Bump sqflite to 1.3.0
• BREAKING CHANGE Remove StubSqlite from StubOfflineFirst. SQLite should be migrated by the repository and data upserted as it would be within the app. StubOfflineFirst is now only concerned with REST responses.
• BREAKING CHANGE Remove interval from OfflineRequestQueue in favor of declaring it once on RequestSqliteCacheManager. To migrate, pass a custom RequestSqliteCacheManager with the interval time to the OfflineFirstWithRestRepository constructor.
• BREAKING CHANGE StubOfflineFirstWithRest must be invoked synchronously (in order to run migrations). When setting up stub in testing, call await StubOfflineFirstWithRest(...).initialize() or, in a cleaner syntax, final stub = StubOfflineFirstWithRest(...); await stub.initialize(). initialize will no longer be automatically invoked.

0.0.6

• Remove maximumRequests configuration for the OfflineFirstQueue. One request should be processed at a time in serial
• Optionally ignore Tunnel not found requests (these occur when connectivity exists but the queried endpoint is unreachable) when making repository requests
• Adds argument to repository to reattempt requests based on the status code from the response
• OfflineRequestQueue#process became a protected method
• Added RequestSqliteCacheManager to interact with the queue. This new class receives most static methods from RequestSqliteCache.
• Added OfflineRequestQueue#requestManager to access queue via a RequestSqliteCacheManager instance.
• Renamed RequestSqliteCache.unprocessedRequests to RequestSqliteCacheManager.prepareNextRequestToProcess as the expected query only returns one locked row at a time.
• RequestSqliteCacheManager.prepareNextRequestToProcess locks all unprocessed rows, not just the first one
• Add ability to toggle serialProcessing for OfflineRequestQueue
• Private member OfflineFirstWithRestRepository#offlineRequestQueue is now protected
• Remove isConnected member from OfflineFirstRepository and associated Connectivity code. The connection should not matter to the subclass as it, or a supporting class, should track outbound requests.

0.0.5+1

• Bump dependencies

0.0.5

• Rename Query#params to Query#providerArgs, reflecting the much narrower purpose of the member

0.0.2

• Export REST annotations/classes from OfflineFirstWithRestRepository for convenient access
• Don't require MemoryCacheProvider in OfflineFirstWithRestRepository as it's not required for OfflineFirstRepository
• Fix linter hints
