From 2231dc5df833a60945caeb0b681eb37ab3100185 Mon Sep 17 00:00:00 2001 From: Taewoon Kim Date: Mon, 3 Nov 2025 11:39:05 +0100 Subject: [PATCH 001/113] feat: Add Python bindings for ArcadeDB embedded database Introduce comprehensive Python bindings that enable embedded ArcadeDB usage directly from Python applications, leveraging JPype for seamless JVM integration. Core Features: - Embedded database operations with full CRUD support - Document, vertex, and edge models for graph databases - Transaction management (read, write, batch operations) - Server mode with HTTP API support - Vector search capabilities for AI/ML applications - Data import from CSV/JSONL with automatic type inference - Export to GraphML, GraphSON, JSONL, and CSV formats - Gremlin query language support - Async execution and batch processing utilities Development Infrastructure: - Multi-platform build system (Linux, macOS, Windows on x64/ARM64) - Native build scripts with JRE bundling - Docker-based build environment - Comprehensive test suite with 100+ tests covering: * Core database operations * Concurrency and transactions * Import/export functionality * Server patterns and API * Type conversions and result handling - CI/CD workflows for automated testing across all platforms - Testing for examples 01-03 (verified working) Examples: - Simple document store with CRUD operations - Social network graph modeling and traversal - Vector similarity search - CSV import with MovieLens dataset (examples 04-05 included but not CI-tested yet) Build System: - Platform-specific wheel generation - JAR exclusion filtering for minimal distributions - Version extraction from parent pom.xml - Setup utilities for streamlined installation This implementation provides a Pythonic interface to ArcadeDB while maintaining compatibility with the Java API and supporting all major platforms. --- .github/workflows/test-python-bindings.yml | 348 ++

Since records are interleaved by @rid (e.g., Question, Answer, +Question, Answer...), scanning 1000 RIDs might only match 50 Answers. This +causes progressive data loss as pagination continues through sparse regions. + +The nested query pattern ensures: +1. Inner query gets N records efficiently via RID pagination (O(1) access) +2. Outer query filters those N records completely (no data loss) +3. All matching records are eventually found across all batches + +Performance Optimization: Index-Based Vertex Lookups +----------------------------------------------------- +For Phase 2 graph creation, vertex caching uses O(1) index lookups instead of +SQL IN queries for dramatically better performance: + +FAST (O(1) per vertex - lookup_by_key): + for vid in vertex_ids: + vertex = graph_db.lookup_by_key("VertexType", ["Id"], [vid]) + if vertex: + cache[vid] = vertex + +SLOW (O(n) - SQL IN operator): + ids_str = ",".join(str(id) for id in vertex_ids) + query = f"SELECT FROM VertexType WHERE Id IN [{ids_str}]" + for result in graph_db.query("sql", query): + cache[result.get("Id")] = result + +Why: SQL IN queries with large ID lists are slow even with indexes.

Updated `pyproject.toml` to clarify the requirement for `py7zr`. - Added `build_graph_now` parameter to `create_vector_index` method in `Database` class to control immediate graph building. - Modified `DatabaseFactory` and `create_database` functions to accept optional JVM arguments for better configuration. - Enhanced `Importer` class to support JVM arguments, improving memory management during data import. - Refined JVM startup logic in `jvm.py` to allow for more flexible configuration and deduplication of heap size arguments. - Introduced tests for OLTP mixed workload scenarios and CSV import handling of complex data types, null values, and performance. - Updated vector index creation tests to verify eager graph building behavior. - Improved documentation and comments throughout the code for clarity and maintainability. * fix(python): correct gremlin labels and robust JVM arg parsing --- .github/workflows/test-python-bindings.yml | 35 +- .github/workflows/test-python-examples.yml | 56 +- .gitignore | 3 + Dockerfile.build | 5 +- README.md | 21 +- build.sh | 13 +- examples/02_social_network_graph.py | 164 + examples/04_csv_import_documents.py | 30 +- examples/06_vector_search_recommendations.py | 40 +- examples/07_stackoverflow_multimodel.py | 6549 ------------------ examples/08_server_mode_rest_api.py | 316 -

Replace that with a new ServerPlugin.isAutoDiscovered(ContextConfiguration) SPI method, default false, that each plugin implements to own its own activation rule. RaftHAPlugin now overrides isAutoDiscovered() with the HA_ENABLED / isHAImplicitlyEnabled() check that used to live in PluginManager's isHAEnabled(), which is now removed along with the RaftHAPlugin name-matching special case. The discovery log line drops the Raft-specific "(auto-discovered for Raft HA)" suffix in favor of a plugin-agnostic "(auto-discovered)" one. This is groundwork for extracting the MCP server into its own module: a later MCPPlugin will override isAutoDiscovered() to activate on classpath presence the same way RaftHAPlugin does today. * refactor(server): extract schema and server-info JSON producers out of MCP Studio's AI assistant (ToolDispatcher, AiChatHandler, AiAnalyzeProfilerHandler) imported MCP types (MCPConfiguration, GetSchemaTool, ServerStatusTool) solely to reach the JSON they render. That import stops compiling once MCP moves into its own module with arcadedb-server at provided scope, so this task moves the two JSON producers the AI code actually needs down into the server module, ahead of that move: - com.arcadedb.server.info.SchemaInfo: renders a database schema as JSON. The body of toJSON is GetSchemaTool.buildSchema moved verbatim; GetSchemaTool and MCPResources now delegate to it. forUser resolves a database for an authenticated user and binds the principal for the duration of the read. - com.arcadedb.server.info.ServerInfo: renders server-level info (version, name, languages, visible databases, optional HA block) behind a caller-supplied visibility predicate; ServerStatusTool now delegates to it. - com.arcadedb.server.security.DatabaseUserContext: extracts the thread-local principal binding out of MCPToolUtils.bindCurrentUser (GHSA-6x73-v3rc-f57c) into a reusable bind()/runAs() pair. MCPToolUtils.bindCurrentUser now delegates to bind(). The AI handlers previously called bindCurrentUser (transitively, via GetSchemaTool.execute/ServerStatusTool.execute) without ever clearing it, because AiChatHandler and AiAnalyzeProfilerHandler extend AbstractServerHttpHandler rather than DatabaseAbstractHandler, which is the only handler that clears the thread-local. SchemaInfo.forUser now binds via DatabaseUserContext.runAs, which restores the previous binding on every exit path including a thrown exception, so the AI path can no longer leak a principal onto a pooled worker thread. SchemaInfo.forUser's unknown-database message is deliberately narrower than MCPToolUtils.resolveDatabase's: it omits the MCP-specific "call list_databases" hint, since the AI path has no such tool. Tests: SchemaInfoTest, ServerInfoTest, DatabaseUserContextTest (new, 7 tests) plus the existing MCPResourcesTest, MCPServerPluginTest, MCPTransportConformanceTest, MCPToolUtilsTest, MCPDatabaseScopingTest, ToolDispatcherTest, AiChatHandlerStreamingTest all pass unchanged. * test(server): pin the array-payload contract against a test-only handler HttpJsonArrayPayloadTest, the regression test for issue ArcadeData/arcadedb#5415, borrowed the MCP endpoint for four of its seven tests purely because MCP happened to be the only in-tree handler opting in to a top-level JSON array body. With MCP moving to its own module, that dependency has to go: relocating the whole file to the MCP module would move a server-pipeline guard out of the module it guards. Add ArrayPayloadTestPlugin, a test-only ServerPlugin/handler pair that opts in via acceptsArrayPayload() and registers /api/v1/test/array. The plugin is not auto-discovered (relies on ServerPlugin.isAutoDiscovered's default false) and only activates when a test names it in SERVER_PLUGINS, requiring a test-scope ServiceLoader registration under META-INF/services so PluginManager's discoverPluginsOnMainClassLoader can find it. Rewrote the four MCP-dependent tests against the new route, exercising the pipeline mechanism directly. The fourth deleted test asserted a JSON-RPC -32700 parse error, which is MCP protocol behavior, not server pipeline behavior. MCPTransportConformanceTest had batch coverage but no parse-error coverage for a malformed top-level array over HTTP, so that assertion was ported there instead of dropped. * refactor(mcp): extract the MCP server into the arcadedb-mcp module Create the arcadedb-mcp Maven module and move the whole MCP implementation into it. 29 main classes move from com.arcadedb.server.mcp to com.arcadedb.mcp and 14 test classes follow them; the package rename is a pure text rewrite, no class body changed except MCPStdioServer.main. A new MCPPlugin owns what ArcadeDBServer used to own: it builds and loads the MCPConfiguration in configure() and registers /api/v1/mcp and /api/v1/mcp/config in registerAPI(). It runs at BEFORE_HTTP_ON, so the configuration is loaded before HttpServer.startService() assembles the routes. It is auto-discovered via META-INF/services and ServerPlugin.isAutoDiscovered, so an upgraded distribution keeps answering on /api/v1/mcp with no SERVER_PLUGINS entry; building a distribution without the module is what removes MCP. ArcadeDBServer loses the MCPConfiguration import, field, initialization block and getMCPConfiguration() accessor. HttpServer loses the two handler imports and the two route registrations. The server module no longer references com.arcadedb.mcp anywhere and compiles with arcadedb-mcp absent from its classpath, so the dependency now runs one way only. MCPStdioServer and the moved tests read the configuration through MCPPlugin.of(server).getConfiguration(). MCPAuthorizationBindingIT moves into the new module but keeps its com.arcadedb.server.security package, because its fixture uses the protected ServerSecurity.getDatabaseGroupsConfiguration. The module declares no third-party dependencies: arcadedb-server at provided scope and its test-jar at test scope, nothing else, and no shade plugin. * test(mcp): pin MCP auto-discovery on classpath presence Adds MCPPluginDiscoveryTest, the one regression test that pins the design decision that nothing else in the suite covers: MCP must activate on classpath presence alone, with no SERVER_PLUGINS entry. This is what an existing installation looks like after upgrading to a distribution where MCP is a separate module, so the /api/v1/mcp endpoint must survive that upgrade unchanged. Every other MCP test reaches its configuration through MCPPlugin.of(...) after the server has already started however it started, so they would all pass just as well if the plugin required explicit configuration. Verified by temporarily flipping MCPPlugin.isAutoDiscovered to return false: all three tests fail (two on a null plugin, one on a 404), then pass again once reverted. * build(mcp): ship arcadedb-mcp in the distribution and expose it to the builder Wire the extracted arcadedb-mcp module into packaging so the standard distribution ships MCP again and the modular builder can select or exclude it. - package/pom.xml: add arcadedb-mcp as a plain (non-shaded) dependency of the standard distribution, after the arcadedb-bolt block. - coverage/pom.xml: add arcadedb-mcp to coverage aggregation. - package/arcadedb-builder.sh: add mcp to REGULAR_MODULES, its description, the --modules= options list, and the OPTIONAL MODULES help block. - package/README-BUILDER.md: document the mcp module as optional. - package/src/main/scripts/mcp-stdio.sh: point the stdio launcher at the new main class com.arcadedb.mcp.MCPStdioServer. * docs(mcp): note the MCPPlugin precondition on the MCP OpenAPI operations * fix(mcp): preserve the join space between MCP operation descriptions and the plugin precondition Java text blocks strip trailing incidental whitespace from every line, including the closing line up to """, so the bare trailing space before the delimiter was silently dropped and the two sentences ran together with no space. Use the \s escape to keep it. * fix(studio): explain an absent MCP module instead of raising an error toast * build(mcp): keep arcadedb-mcp out of the Python wheel and in the native image The Python package is embedded-only: it already drops arcadedb-server, Undertow and Micrometer. arcadedb-mcp matched no exclusion pattern, so extracting MCP out of the server jar would have shipped it into the wheel, where every one of its classes references com.arcadedb.server.* that is not present. The native image lost /api/v1/mcp for the mirror-image reason: it lists every wire-protocol module explicitly, and MCP used to arrive for free inside arcadedb-server. Add the dependency, plus the reflection entry PluginManager's ServiceLoader lookup needs, matching the ten other ServerPlugin implementations already registered there. The META-INF/services resource is already covered by the existing path glob. * fix(mcp): publish the plugin fields safely and repair the tool Javadoc MCPPlugin.of() is public API now. PluginManager publishes the plugin instance into its map during discovery and only calls configure() later, so getPlugins()' synchronized(plugins) gives a reader no happens-before edge with the field writes that follow the insertion. Mark both fields volatile, following the convention ArcadeDBServer documents on security/httpServer/haServer. MCPToolUtils.bindCurrentUser's Javadoc still linked DatabaseContext after the import was dropped in the module extraction, so both links dangled; qualify them like the MCPDispatcher link beside them. Also drop two em dashes the rename carried over. * test(mcp): make the extraction's tests assert what their names claim PluginAutoDiscoveryTest restated the SPI: reverting PluginManager to the hardcoded class-name match left it green. Narrow it to the one claim that carries weight, that the isAutoDiscovered default answers false so a plugin stays gated behind SERVER_PLUGINS, and rename it to say so. Registering a genuinely auto-discovered plugin in the server's own META-INF/services would start it in every server test and in every module consuming the server test-jar, so the end-to-end route stays covered by MCPPluginDiscoveryTest where a real one ships. SchemaInfoTest now asserts the calling thread carries no bound principal once forUser returns. Swapping runAs for bind in SchemaInfo makes it fail with "but was: root"; before this, that swap left the whole suite green even though it leaks a principal onto a pooled request thread. MCPAuthorizationBindingIT declared com.arcadedb.server.security purely to reach one protected method, which would have been the repository's first package split across two artifacts, held together only while both jars share a class loader. Put the accessor in the server's own test tree, where ServerSecurity already documents such setup helpers, and move the IT to com.arcadedb.mcp. The call resolves the same live wildcard groups object, so the fixture plants its group exactly where it did. Return the issue ArcadeData/arcadedb#5415 malformed-array case to the server module. The pipeline swallows the parse failure and invokes the handler with a null payload and a null array; the JSON-RPC -32700 is MCP's own recovery layered on top, so the server-side test asserts the pipeline behavior instead. --- scripts/jar_exclusions.txt | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/scripts/jar_exclusions.txt b/scripts/jar_exclusions.txt index b34022bc..5e5f5ea4 100644 --- a/scripts/jar_exclusions.txt +++ b/scripts/jar_exclusions.txt @@ -23,7 +23,10 @@ arcadedb-tracing-*.jar jline-*.jar # Server mode removed 2026-07-05 (embedded-only package; use the official # ArcadeDB server distribution/Docker image for client-server deployments). -# micrometer was only kept for server startup, so it goes with the stack: +# micrometer was only kept for server startup, so it goes with the stack. +# arcadedb-mcp is a server plugin: every class in it references com.arcadedb.server.*, so it is dead +# weight (and unloadable) once the server jar is gone. +arcadedb-mcp-*.jar arcadedb-server-*.jar arcadedb-studio-*.jar undertow-*.jar From 2d68dd22a0a55a13e18cc0373e60c086cce43609 Mon Sep 17 00:00:00 2001 From: Taewoon Kim Date: Tue, 4 Aug 2026 13:57:17 +0200 Subject: [PATCH 059/113] Update Python bindings for 26.8.1: server mode restored, ResultSet.to_arrow(), wire-protocol tests (ArcadeData/arcadedb#5807) --- .github/workflows/test-python-bindings.yml | 33 +- .github/workflows/test-python-examples.yml | 63 +- README.md | 31 +- examples/.gitignore | 7 + examples/02_social_network_graph.py | 26 +- examples/03_vector_search.py | 3 +- examples/12_vector_search.py | 24 + examples/22_numpy_bulk_io.py | 207 +++++ examples/23_server_mode_http_access.py | 423 ++++++++++ examples/README.md | 93 ++- examples/download_data.py | 21 +- pyproject.toml | 38 + scripts/arrow_transport_probe.py | 147 ++++ scripts/build.sh | 36 +- scripts/jar_exclusions.txt | 17 +- src/arcadedb_embedded/__init__.py | 37 +- src/arcadedb_embedded/async_executor.py | 209 ++++- src/arcadedb_embedded/citation.py | 77 +- src/arcadedb_embedded/core.py | 116 ++- src/arcadedb_embedded/graph.py | 2 +- src/arcadedb_embedded/graph_batch.py | 11 +- src/arcadedb_embedded/jvm.py | 183 ++++- src/arcadedb_embedded/results.py | 183 ++++- src/arcadedb_embedded/schema.py | 28 +- src/arcadedb_embedded/server.py | 259 ++++++ src/arcadedb_embedded/type_conversion.py | 17 +- src/arcadedb_embedded/vector.py | 54 +- .../com/arcadedb/python/ColumnBatcher.java | 57 +- .../com/arcadedb/python/DocumentBatcher.java | 81 ++ .../arcadedb/python/TimeSeriesBatcher.java | 64 ++ tests/README.md | 45 +- tests/conftest.py | 51 ++ tests/test_bulk_insert.py | 268 ++++++ tests/test_citation.py | 66 ++ tests/test_core.py | 2 +- tests/test_docs_examples.py | 36 + tests/test_import_database.py | 34 +- tests/test_jar_provenance.py | 148 ++++ tests/test_jvm.py | 83 ++ tests/test_resultset_arrow.py | 138 ++++ tests/test_server.py | 135 ++++ tests/test_server_packaging.py | 143 ++++ tests/test_server_patterns.py | 763 ++++++++++++++++++ tests/test_server_wire_protocols.py | 185 +++++ tests/test_type_conversion.py | 39 + tests/test_vector.py | 135 +++- tests/test_vector_params_verification.py | 14 +- tests/test_vector_sql.py | 19 +- tests/test_wheel_platform_tag.py | 21 + 49 files changed, 4641 insertions(+), 231 deletions(-) create mode 100644 examples/22_numpy_bulk_io.py create mode 100644 examples/23_server_mode_http_access.py create mode 100644 scripts/arrow_transport_probe.py create mode 100644 src/arcadedb_embedded/server.py create mode 100644 src/java/com/arcadedb/python/DocumentBatcher.java create mode 100644 src/java/com/arcadedb/python/TimeSeriesBatcher.java create mode 100644 tests/test_bulk_insert.py create mode 100644 tests/test_citation.py create mode 100644 tests/test_jar_provenance.py create mode 100644 tests/test_jvm.py create mode 100644 tests/test_resultset_arrow.py create mode 100644 tests/test_server.py create mode 100644 tests/test_server_packaging.py create mode 100644 tests/test_server_patterns.py create mode 100644 tests/test_server_wire_protocols.py diff --git a/.github/workflows/test-python-bindings.yml b/.github/workflows/test-python-bindings.yml index 9de313c2..3fa5b94f 100644 --- a/.github/workflows/test-python-bindings.yml +++ b/.github/workflows/test-python-bindings.yml @@ -122,7 +122,7 @@ jobs: for v in $versions; do echo "::group::Resolve floors for Python $v" uv pip compile pyproject.toml \ - --extra test --extra vector --extra examples \ + --extra test --extra vector --extra examples --extra arrow --extra pandas \ --resolution lowest-direct \ --python-version "$v" \ -o "$RUNNER_TEMP/floors-$v.txt" @@ -327,7 +327,12 @@ jobs: shell: bash run: | cd bindings/python - uv pip install --system test-install/*.whl pytest pytest-cov requests numpy + # This list is hand-maintained and mirrors the `test` extra.

ArcadeData/arcadedb#6758 The Python bindings' ColumnBatcher built its JSON header by concatenating raw column names, so an alias carrying a quote produced invalid JSON and broke the decode of the whole batch; a semicolon additionally split one name into two bogus columns through the ';'-joined column spec. The header now goes through JSONObject/JSONArray like its sibling RowBatcher, and the column spec is a JSON array (the legacy form is still accepted). ArcadeData/arcadedb#6759 Polyglot script parameters were bound to the shared context and never removed, so a value one command passed stayed readable by every later command on that database, from any caller. Parameters are now scoped to one evaluation, snapshotting and restoring whatever they displaced so a parameter may still shadow an engine binding for the duration of its own command. A timed-out script is additionally cancelled through GraalVM's supported Context.interrupt rather than only Thread.interrupt, which is what actually releases the shared context; the engine field is volatile and guarded by a stable lock, and unregisterFunctions no longer leaks the context it replaces. ArcadeData/arcadedb#6760 A snapshot install that gave up on a database (3 consecutive failures) still recorded the snapshot index as applied for EVERY database, cleared the read floor and the diverged marks, and returned the installed TermIndex to Ratis. The node re-entered the ready set advertising itself fully caught up while one database was still stale, so LINEARIZABLE and read-your-writes reads of it were served from the old copy. The reconciler now reports the databases it gave up on, and the install leaves each of them diverged, at its own honest persisted position, and behind a per-database read floor that only clamps reads of that database. The HealthMonitor backstop treats such a floor as an unfilled gap, so the resync keeps being retried. ArcadeData/arcadedb#6761 The network layer never enabled TCP keepalive while the Postgres and Redis executors deliberately set an infinite socket read timeout after authentication, so a half-open connection pinned a thread and a file descriptor forever with no application heartbeat to notice. Keepalive is now on by default with configurable probe timings. Also in the same file: close() shut the input side (and with it the socket) before the output side, silently dropping buffered bytes, and ChannelBinaryClient's cleanup catch handled only RuntimeException while every connect failure path throws a checked one. ArcadeData/arcadedb#6762 Grouped robustness batch: PluginManager now stops a plugin whose startService() threw, so what it acquired before failing is released instead of leaking; a WebSocket watcher stops accepting events while the per-database lock still excludes a concurrent subscribe, closing a duplicate-delivery race; change-stream authorization is re-checked on delivery rather than only at SUBSCRIBE; a slow subscriber is evicted past a configurable outstanding-bytes cap instead of accruing an unbounded send backlog; a failed vector-index materialisation advances the id allocator over whatever was read, so the next insert cannot supersede a live vector; RemoteGrpcServer's channel is volatile and read once per decision; and profiler_start, query and execute_command re-validate their numeric inputs server-side like their sibling tools. --- src/arcadedb_embedded/results.py | 7 ++- .../com/arcadedb/python/ColumnBatcher.java | 52 +++++++++++++++---- tests/test_core.py | 26 ++++++++++ 3 files changed, 73 insertions(+), 12 deletions(-) diff --git a/src/arcadedb_embedded/results.py b/src/arcadedb_embedded/results.py index 0775870b..459e869c 100644 --- a/src/arcadedb_embedded/results.py +++ b/src/arcadedb_embedded/results.py @@ -330,7 +330,9 @@ def decode_batch(buf): break total += count if first_names is not None and not joined: - joined = ";".join(first_names) # keep column set stable + # JSON, not ";".join: a projection alias may legally contain a semicolon, a quote or a + # backslash, and the legacy separator split such a name into two bogus columns. + joined = json.dumps(first_names) # keep column set stable if total == 0: return {} @@ -470,7 +472,8 @@ def decode_batch(buf): break total += count if first_names is not None and not joined: - joined = ";".join(first_names) + # See to_columns: the column spec is JSON so odd-but-legal aliases survive the round trip. + joined = json.dumps(first_names) if total == 0 or not first_names: return pa.table({}) diff --git a/src/java/com/arcadedb/python/ColumnBatcher.java b/src/java/com/arcadedb/python/ColumnBatcher.java index 49edbc52..cca4ee60 100644 --- a/src/java/com/arcadedb/python/ColumnBatcher.java +++ b/src/java/com/arcadedb/python/ColumnBatcher.java @@ -13,6 +13,8 @@ import com.arcadedb.query.sql.executor.Result; import com.arcadedb.query.sql.executor.ResultSet; +import com.arcadedb.serializer.json.JSONArray; +import com.arcadedb.serializer.json.JSONObject; import java.io.ByteArrayOutputStream; import java.nio.ByteBuffer; @@ -47,8 +49,8 @@ private static long toEpochMillis(final Object v) { } public static byte[] nextColumnBatch(final ResultSet rs, final int max, final String joinedColumns) { - // empty joinedColumns: derive the column set from the first row - String[] columns = joinedColumns.isEmpty() ? null : joinedColumns.split(";"); + // empty column spec: derive the column set from the first row + String[] columns = parseColumnSpec(joinedColumns); final List results = new ArrayList<>(Math.min(max, 1 << 16)); while (results.size() < max && rs.hasNext()) results.add(rs.next()); @@ -68,7 +70,11 @@ public static byte[] nextColumnBatch(final ResultSet rs, final int max, final St } final int count = rows.size(); - final StringBuilder header = new StringBuilder("{\"count\":" + count + ",\"cols\":["); + // The header goes through JSONObject/JSONArray rather than string concatenation: a column name is an + // arbitrary query projection alias, so a name carrying a quote, a backslash or a control character used to + // emit invalid JSON and break the decode of the WHOLE batch on the Python side.

The waiter saw the raw Ratis index, which already equals snapshotIndex, so a LINEARIZABLE or read-your-writes read of a database the install did NOT refresh passed its wait and was served from the stale copy - exactly the outcome ArcadeData/arcadedb#6760 exists to prevent, reopened in a narrower window by the ordering. The notify now runs last, after every floor and diverged mark is final. The new test captures the floor at the instant of the notify, so it is deterministic rather than racing threads, and it fails against the old order. WebSocket (ArcadeData/arcadedb#6762): the backlog is charged in UTF-8 BYTES rather than characters - the cap is expressed in bytes and what sits in the send buffer is what sendText encodes, up to 3 bytes per CJK char and 4 per emoji, so counting chars let a non-ASCII change stream hold several times the configured budget. Computed in one pass instead of getBytes(UTF_8).length, which would copy the whole payload per event. releasePending() is also floored at zero: a client that unsubscribes and re-subscribes mid-flight lands its completion callback on the replacement subscription, and letting that go negative would have given the replacement a negative baseline that silently raised its cap. Flooring it keeps the shared per-event callback, which is there to avoid an allocation per subscriber per event. Polyglot (ArcadeData/arcadedb#6759): the timeout path now interrupts only the context the timed-out task actually entered, recorded when it enters the synchronized block. Re-reading the shared field could cancel a script belonging to ANOTHER caller when our own task was still queued and never ran, and could interrupt a context unregisterFunctions() had replaced in the meantime. gRPC (ArcadeData/arcadedb#6762): a `closing` flag is set as close() begins, so channel() refuses from that point instead of handing out a terminating channel - and, once close() nulled the field, silently building a brand-new channel for a server the caller had explicitly closed. An explicit start() still clears it, so a deliberate restart works. Python bindings (ArcadeData/arcadedb#6758): the alias test now runs with batch_size=2 so its three rows span more than one non-empty batch. The column spec is only sent back to Java from the second batch onwards, so a single-batch result never exercised the round trip the ';'-joined form used to break. --- tests/test_core.py | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/tests/test_core.py b/tests/test_core.py index 83944e97..940eee9d 100644 --- a/tests/test_core.py +++ b/tests/test_core.py @@ -1129,10 +1129,13 @@ def test_to_columns_survives_json_metacharacters_in_aliases(temp_db_path): for i in range(3): db.command("sql", "INSERT INTO T SET n = ?, s = ?", i, f"v{i}") + # batch_size=2 so the three rows span MORE THAN ONE non-empty batch: the column spec is only sent back + # to Java from the second batch onwards, so a single-batch result would never exercise the round trip + # that the ';'-joined form used to break. cols = db.query( "sql", "SELECT s AS `{}`, n AS `{}` FROM T ORDER BY n".format(weird, semi), - ).to_columns() + ).to_columns(batch_size=2) assert cols is not None assert sorted(cols.keys()) == sorted([weird, semi]) assert list(cols[weird]) == ["v0", "v1", "v2"] From f65a1ac739c00bbf90d7ff7a7ac80369923a0aa1 Mon Sep 17 00:00:00 2001 From: Taewoon Kim Date: Sat, 29 Aug 2026 17:16:09 +0900 Subject: [PATCH 065/113] Update Python bindings: GraphBatch retry/cache knobs, importer on_row_error, RESTORE and wire-protocol tests (ArcadeData/arcadedb#6790) --- src/arcadedb_embedded/core.py | 36 ++++ src/arcadedb_embedded/graph_batch.py | 19 +++ src/arcadedb_embedded/importer.py | 26 +++ tests/test_core.py | 10 +- tests/test_graph_batch.py | 94 ++++++++++ tests/test_importer_api.py | 79 +++++++++ tests/test_restore_sql.py | 246 +++++++++++++++++++++++++++ tests/test_server_wire_protocols.py | 42 ++--- 8 files changed, 526 insertions(+), 26 deletions(-) create mode 100644 tests/test_restore_sql.py diff --git a/src/arcadedb_embedded/core.py b/src/arcadedb_embedded/core.py index 5f29379f..85fa2f96 100644 --- a/src/arcadedb_embedded/core.py +++ b/src/arcadedb_embedded/core.py @@ -834,6 +834,10 @@ def graph_batch( wal_flush: Optional[str] = None, pre_allocate_edge_chunks: Optional[bool] = None, parallel_flush: Optional[bool] = None, + commit_retries: Optional[int] = None, + commit_retry_delay_ms: Optional[int] = None, + chunk_cache_capacity: Optional[int] = None, + max_deferred_incoming_edges: Optional[int] = None, ) -> GraphBatch: """ Create a GraphBatch helper for high-throughput graph ingestion. @@ -853,6 +857,24 @@ def graph_batch( wal_flush: WAL flush mode: `"no"`, `"yes_nometadata"`, `"yes_full"`. pre_allocate_edge_chunks: Pre-allocate edge chunks during `create_vertex()`. parallel_flush: Parallelize flush/close connectivity work across buckets. + commit_retries: Times a vertex-creation commit is retried on a transient + `NeedRetryException` (for example a Raft `QuorumNotReachedException` + during a leader re-election).
