From 1082aa1e543bffcfc8df6822e5768db96ff3a71e Mon Sep 17 00:00:00 2001 From: Rawk AKani Date: Sat, 27 Sep 2025 17:49:14 +0000 Subject: [PATCH 01/42] Add Rocky Linux setup script and PostgreSQL integration testing - Add setup-rocky-linux.sh: Comprehensive setup script for Rocky Linux VMs - Add docker-compose.test.yml: PostgreSQL test container configuration - Add test-postgres.sh: PostgreSQL integration test script - Add postgres/ directory: PostgreSQL backend implementation - Add ROCKY_LINUX_SETUP.md: Documentation for Rocky Linux setup - Update Cargo.toml files: Add PostgreSQL dependencies - Update various source files: PostgreSQL integration support The setup script installs all necessary dependencies including: - Development tools and PostgreSQL dev libraries - Docker and Docker Compose - Rust toolchain - Clones repository and builds project - Creates test environment for PostgreSQL KV integration --- ROCKY_LINUX_SETUP.md | 85 ++++++ docker-compose.test.yml | 21 ++ postgres/Cargo.toml | 31 ++ postgres/backend.rs | 518 ++++++++++++++++++++++++++++++++++ postgres/config.rs | 59 ++++ postgres/error.rs | 89 ++++++ postgres/lib.rs | 176 ++++++++++++ postgres/message_handle.rs | 56 ++++ postgres/notifier.rs | 82 ++++++ postgres/src/migration.rs | 256 +++++++++++++++++ postgres/tests/integration.rs | 164 +++++++++++ setup-rocky-linux.sh | 259 +++++++++++++++++ test-postgres.sh | 32 +++ 13 files changed, 1828 insertions(+) create mode 100644 ROCKY_LINUX_SETUP.md create mode 100644 docker-compose.test.yml create mode 100644 postgres/Cargo.toml create mode 100644 postgres/backend.rs create mode 100644 postgres/config.rs create mode 100644 postgres/error.rs create mode 100644 postgres/lib.rs create mode 100644 postgres/message_handle.rs create mode 100644 postgres/notifier.rs create mode 100644 postgres/src/migration.rs create mode 100644 postgres/tests/integration.rs create mode 100755 setup-rocky-linux.sh create mode 100755 test-postgres.sh diff --git a/ROCKY_LINUX_SETUP.md b/ROCKY_LINUX_SETUP.md new file mode 100644 index 0000000..00b7019 --- /dev/null +++ b/ROCKY_LINUX_SETUP.md @@ -0,0 +1,85 @@ +# Rocky Linux Setup for DenoKV PostgreSQL Testing + +This document describes how to set up a Rocky Linux environment for testing DenoKV PostgreSQL integration. + +## Prerequisites + +- Rocky Linux 8 or 9 +- Internet connection +- Non-root user with sudo privileges + +## Quick Setup + +Run the setup script: + +```bash +chmod +x setup-rocky-linux.sh +./setup-rocky-linux.sh +``` + +## What the Setup Script Does + +1. **Updates system packages** -

This caused stale locks (e.g. cron leader keys) to persist indefinitely, blocking all workers. Changes: - Filter expired keys in `read_range` queries (WHERE expires_at IS NULL OR expires_at > now) - Treat expired keys as non-existent in `atomic_write` checks - Add `collect_expired()` method + 60s background task to delete expired rows - Add `queue_cleanup()` method + 30s background task to requeue dead messages - Fix `message_handle::finish()` to support backoff schedule and keys_if_undelivered (matching SQLite backend behavior) Co-Authored-By: Claude Opus 4.6 (1M context) --- postgres/backend.rs | 85 ++++++++++++++++++++++++++++++++++--- postgres/lib.rs | 46 +++++++++++++++++++- postgres/message_handle.rs | 87 ++++++++++++++++++++++++++++++++------ 3 files changed, 199 insertions(+), 19 deletions(-) diff --git a/postgres/backend.rs b/postgres/backend.rs index 3b85f7b..c4a45bd 100644 --- a/postgres/backend.rs +++ b/postgres/backend.rs @@ -105,17 +105,19 @@ impl PostgresBackend { Ok(()) } - /// Read a range of keys + /// Read a range of keys, excluding expired entries. pub async fn read_range( &self, conn: &Client, request: &ReadRange, ) -> PostgresResult> { + let now_ms = Utc::now().timestamp_millis(); let query = if request.reverse { r#" SELECT key, value, value_encoding, versionstamp FROM kv_store WHERE key >= $1 AND key < $2 + AND (expires_at IS NULL OR expires_at > $4) ORDER BY key DESC LIMIT $3 "# @@ -124,6 +126,7 @@ impl PostgresBackend { SELECT key, value, value_encoding, versionstamp FROM kv_store WHERE key >= $1 AND key < $2 + AND (expires_at IS NULL OR expires_at > $4) ORDER BY key ASC LIMIT $3 "# @@ -133,6 +136,7 @@ impl PostgresBackend { &request.start, &request.end, &(request.limit.get() as i64), + &now_ms, ]).await?; let mut entries = Vec::new(); @@ -174,15 +178,16 @@ impl PostgresBackend { ) -> PostgresResult> { let tx = conn.transaction().await?; - // Perform checks + // Perform checks โ€” treat expired keys as non-existent + let now_ms = Utc::now().timestamp_millis(); for check in &write.checks { let row = tx.query_opt( - "SELECT versionstamp FROM kv_store WHERE key = $1", - &[&check.key], + "SELECT versionstamp FROM kv_store WHERE key = $1 AND (expires_at IS NULL OR expires_at > $2)", + &[&check.key, &now_ms], ).await?; let current_versionstamp = row.map(|r| r.get::<_, Vec>("versionstamp")); - + if let Some(expected) = &check.versionstamp { if current_versionstamp.as_ref().map(|v| v.as_slice()) != Some(expected.as_slice()) { return Ok(None); // Check failed @@ -503,6 +508,76 @@ impl PostgresBackend { } } + /// Delete all expired keys.

Atomic concurrency: READ COMMITTED isolation allowed two concurrent atomic writes to both pass the same versionstamp check. Fixed by using SERIALIZABLE isolation and catching serialization failures (40001) as check conflicts (returns ok: false instead of 500). 2. Watch hanging: notify_key_update() was defined but never called after mutations, so watchers blocked forever. Added notification of watchers in atomic_write after successful commits. Also adds comprehensive test scripts for all KV operations and postgres-specific features (expiration filtering, concurrency, etc).

charset=UTF-8 Content-Transfer-Encoding: 8bit Replace SERIALIZABLE isolation + serialization error catching with a monotonic version counter in a `data_version` table, matching the SQLite backend design. UPDATE ... RETURNING on the single version row takes an exclusive row lock, serializing all writers under plain READ COMMITTED isolation. Concurrent writers queue up instead of aborting โ€” no 500 errors, no retries needed. The second writer blocks until the first commits, then sees the updated versionstamp and fails the check cleanly. This is the standard pessimistic locking pattern used in fintech for transaction serialization (SELECT FOR UPDATE / UPDATE RETURNING).
