phorm_sqlite 1.10.2

The SQLite driver and connection manager implementation for the PHORM.

Changelog

1.10.2

• Fix Unsupported operation: Platform._operatingSystem on Flutter Web. DB touched dart:io (Platform in getDatabasesPath, File in downgrade/reset/version checks) on every open; on web those are stubs that throw at runtime. All filesystem/platform code is now guarded with kIsWeb: the database name is passed straight to the IndexedDB-backed store, and file cleanup steps are skipped on web.
• Fix SqliteException(14) on desktop first launch. The default database location (.../Application Support/<app>/databases/) was never created; SQLite does not create intermediate directories, so opening the database failed on a fresh install (macOS/Windows/Linux). The parent directory is now created before opening.

1.10.1

• Fix Flutter Web builds. database_adapter.dart imported package:sqlite3/sqlite3.dart (the FFI entry point) for SqliteException, which pulled dart:ffi into web compilations and failed them. It now imports the web-safe package:sqlite3/common.dart.

1.10.0

• Database and Transaction implement the new ColumnarQueryExecutor capability from phorm ^1.9.0: SELECT results cross the isolate boundary in columnar form end-to-end, enabling the core's faster model-read path. The DatabaseIsolate backend interface gains queryColumnar (native returns the isolate's packed result directly; web adapts its map-based results).

1.9.0

• Bulk operation performance (5k-row insert: ~41ms → ~7ms on an Apple M3):
  • batches of same-shape inserts are coalesced into a columnar BatchInsertMany — column names cross the isolate boundary once and the isolate reuses a single prepared statement for all rows;
  • table-change notifications from the SQLite update hook are buffered during batches/transactions and flushed once per distinct table after COMMIT, instead of one cross-isolate message per affected row;
  • SELECT results use a columnar transfer (column names once + value lists) instead of one map per row, with maps rebuilt caller-side sharing key instances.
• Reactive watch*/changeStream semantics are unchanged: listeners still receive one event per modified table after commit.

1.8.0

• Batch operations are ~11× faster. Batch.commit() now sends plain insert/update/delete batches to the database isolate as a single message executed there in one transaction, instead of one isolate round-trip per operation (5000 inserts: ~457ms → ~41ms on an Apple M3). Falls back to the previous per-operation path when results are requested (noResult: false), continueOnError is set, raw SQL is batched, a non-REPLACE conflict algorithm is used, or an outer transaction is active.
• DB(onQuery: ...) query observer — a callback invoked for every database operation, independently of logQueries: successful, slow (per slowQueryThreshold) and failed ones (with error and stack trace). Feed it to metrics, tracing or crash reporting. Requires phorm ^1.8.0.

1.7.0

• Nested transactions via SQLite savepoints. transaction() can now be called inside another transaction: the outermost call issues BEGIN/COMMIT as before, inner calls create a SAVEPOINT that is released on success or rolled back on failure. A failed inner transaction undoes only its own writes and does not poison the outer one; an outer rollback still reverts everything. Previously a nested call failed with "cannot start a transaction within a transaction".

1.6.1

• Bumped bundled phorm core to ^1.5.0, bringing typed condition composition with the & / | operators (age.gt(18) & (city.eq('Sofia') | city.eq('Plovdiv'))).
• phorm_generator stays pinned <1.4.0: generator 1.4.x needs analyzer ^13 (meta ^1.18.3), which conflicts with the meta version pinned by flutter_test on the current Flutter stable.

1.6.0

• New: automatic additive migrations — DB(autoMigrate: true) (also on DB.autoVersion). On every open, each registered table's live schema is compared with its generated CREATE TABLE schema; missing tables, columns, indexes and triggers are created automatically — no version bump needed for additive model changes. Destructive or ambiguous changes (dropped/renamed columns, type changes, NOT NULL without a DEFAULT, UNIQUE/ PRIMARY KEY additions) are never applied: they are logged with a suggestion to write an explicit TableMigration. Off by default; explicit migrations keep working alongside and remain the tool for data transforms.
• Re-enabled most very_good_analysis lints for lib/ (generated *.g.dart files are excluded from analysis). Internal cleanups with no behavior changes: on Object catch clauses, removed unnecessary awaits, single changeStream tear-off subscription.

1.5.1

• Bundled phorm core bumped to ^1.4.1: WhereBuilder now escapes columns structurally via the dialect instead of regex replacement over the generated SQL, fixing mis-escaping when a column name coincided with a word inside the SQL template (e.g. a column named LOWER or DATE) and properly escaping SqlFunctionColumn inner columns.

1.5.0

• BREAKING: bundled phorm core bumped to ^1.4.0 — automatic timestamps (created_at, updated_at, deleted_at) are now written in UTC instead of local time. New records sort consistently across devices/timezones; rows written by earlier versions keep their local-time values.
• Migration applied_at timestamps are now written in UTC as well.

1.4.1

• Raise the default DB.isolateThreshold from 50 to 2000. Result-set parsing only moves to a background isolate once inline parsing would risk a dropped frame; below that the isolate spawn + row copy was pure overhead. See benchmark/parse_benchmark.dart in the phorm package for the measurements.
• Document the isolateThreshold tuning knob in the README.

1.4.0

• Upgrade to sqlite3 ^3.3.4, sqlite3_flutter_libs ^0.6.0 and sqlite3_web ^0.9.2. Migrate the isolate backends off the deprecated dispose() in favor of close(). Raises the Dart SDK floor to >=3.10.0 (required by sqlite3_web 0.9).
• Add topics to pubspec.yaml for pub.dev discoverability.
• Note: the phorm_generator dev-dependency is temporarily pinned to <1.4.0, as generator 1.4.0 pulls analyzer 13 (meta ^1.18.3) which conflicts with the meta version pinned by the current Flutter SDK.

1.3.0

• Auto-generated pivot tables (from @ManyToMany(createPivot: true)) are now created on database upgrade as well, not only on first creation: any IF NOT EXISTS-guarded statement in a table's schema is re-applied when the owning table already exists.
• Added an informational log line when a pivot table is created alongside its model table (e.g. Also creating pivot table: user_roles).

1.2.0

• Bumped phorm dependency to ^1.2.0 (and phorm_generator dev dependency to ^1.2.0), exposing the new @Schema(generateFullService: ...) option.
• Bumped sqlite3_web to ^0.4.1.

1.1.0

• Bumped phorm dependency to ^1.1.0 and phorm_generator (dev) to ^1.1.0.
• Version bump to keep all PHORM packages in sync.

1.0.3

• Version bump to keep all PHORM packages in sync.

1.0.2

• Updated SDK environment constraint to >=3.7.0 <4.0.0

• Removed commented workspace resolution configuration

1.0.0

• First stable release of the PHORM SQLite Driver.
• Implements phorm runtime database execution layer on top of sqlite3.
• Dedicated multi-thread background isolate executor ensuring synchronous SQLite operations never block the main/UI thread.
• Out-of-the-box Flutter Web support via WebAssembly (sqlite3_web) and persistent IndexedDB file system.
• Transparent database versioning and smart idempotent migration lifecycle tracking via the __phorm_migrations table.
• High-performance slow query tracer and console loggers.
• Built-in SQLCipher encryption support for Native (iOS, Android, Desktop) platforms.
• Native Dart SqlFunction registration (including regexp support).
