From 05370faf2baf47db8296cdd26b7d9685fdf1d9d9 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 22 Nov 2025 22:27:30 +0000 Subject: [PATCH 01/15] Add Funz server runner support (funz:// calculator type) Implements support for connecting to legacy Java Funz calculator servers via the Funz protocol. This allows FZ to integrate with existing Funz server infrastructure. Features: - Text-based TCP socket communication with Funz servers - Calculator reservation and authentication - Automatic file upload/download - Result archive extraction - Interrupt handling support - Automatic cleanup and unreservation Usage: calculators = "funz://:5555/R" calculators = "funz://server.example.com:5555/Python" Protocol implementation based on: https://github.com/Funz/funz-client/blob/master/src/main/java/org/funz/run/Client.java Changes: - fz/runners.py: Add run_funz_calculation() and funz:// URI support - tests/test_funz_runner.py: Add basic tests for Funz runner - README.md: Document Funz server execution in Calculator Types - CLAUDE.md: Update runners.py description --- CLAUDE.md | 3 +- README.md | 54 ++++++ fz/runners.py | 354 +++++++++++++++++++++++++++++++++++++- tests/test_funz_runner.py | 111 ++++++++++++ 4 files changed, 520 insertions(+), 2 deletions(-) create mode 100644 tests/test_funz_runner.py diff --git a/CLAUDE.md b/CLAUDE.md index 6fc328f..bbca323 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -78,9 +78,10 @@ The codebase is organized into functional modules (~5700 lines total): - Support for default values: `${var~default}` - Multi-line function definitions in formulas -- **`fz/runners.py`** (1345 lines) - Calculator execution engines +- **`fz/runners.py`** (~1800 lines) - Calculator execution engines - **Local shell execution** (`sh://`) - runs commands in temporary directories - **SSH remote execution** (`ssh://`) - remote HPC/cluster support with file transfer + - **Funz server execution** (`funz://`) - connects to legacy Java Funz calculator servers via TCP socket protocol - **Cache calculator** (`cache://`) - reuses previous results by input hash matching - Host key validation, authentication handling, timeout management diff --git a/README.md b/README.md index 4e7ca57..fbcae19 100644 --- a/README.md +++ b/README.md @@ -989,6 +989,60 @@ calculators = "ssh://user@server.com:2222/bash /absolutepath/to/calc.sh" - Warning for password-based auth - Environment variable for auto-accepting host keys: `FZ_SSH_AUTO_ACCEPT_HOSTKEYS=1` +### Funz Server Execution + +Execute calculations using the Funz server protocol (compatible with legacy Java Funz servers): + +```python +# Connect to local Funz server +calculators = "funz://:5555/R" + +# Connect to remote Funz server +calculators = "funz://server.example.com:5555/Python" + +# Multiple Funz servers for parallel execution +calculators = [ + "funz://:5555/R", + "funz://:5556/R", + "funz://:5557/R" +] +``` + +**Features**: +- Compatible with legacy Java Funz calculator servers +- Automatic file upload to server +- Remote execution with the Funz protocol +- Result download and extraction +- Support for interrupt handling + +**Protocol**: +- Text-based TCP socket communication +- Calculator reservation with authentication +- Automatic cleanup and unreservation + +**URI Format**: `funz://[host]:/` +- `host`: Server hostname (default: localhost) +- `port`: Server port (required) +- `code`: Calculator code/model name (e.g., "R", "Python", "Modelica") + +**Example**: +```python +import fz + +model = { + "output": { + "pressure": "grep 'pressure = ' output.txt | awk '{print $3}'" + } +} + +results = fz.fzr( + "input.txt", + {"temp": [100, 200, 300]}, + model, + calculators="funz://:5555/R" +) +``` + ### Cache Calculator Reuse previous calculation results: diff --git a/fz/runners.py b/fz/runners.py index d5244e0..68aafbc 100644 --- a/fz/runners.py +++ b/fz/runners.py @@ -291,7 +291,7 @@ def _validate_calculator_uri(calculator_uri: str) -> None: #

Date: Mon, 24 Nov 2025 12:51:21 +0000 Subject: [PATCH 15/15] Add comprehensive Funz protocol tests (TCP/UDP) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements Python equivalents of Java tests from: - NetworkTest.java (funz-calculator) - ClientTest.java (funz-client) New test file: tests/test_funz_protocol.py Test Coverage: - Low-level TCP protocol communication - Connection/disconnection handling - Calculator reservation and unreservation - File upload/download via protocol - Full protocol cycle (reserve → upload → execute → download → unreserve) - Multiple sequential cases (like test10Cases) - Concurrent client connections (like testListening) - Reservation timeout behavior (like testReserveTimeOut) - Failed execution handling (like testFailedCase) - Client disconnection during operation (like testCaseBreakClient) - Activity and info queries FunzProtocolClient class: - Low-level protocol implementation - Methods: connect, reserve, unreserve, put_file, execute, get_results - Protocol constants matching Java implementation - Support for heartbeats, info messages, and error handling Test methods: 1. test_connection - Basic TCP connection 2. test_reserve_unreserve - Reservation cycle 3. test_get_activity - Activity status queries 4. test_get_info - Calculator info queries 5. test_full_protocol_cycle - Complete protocol flow 6. test_multiple_sequential_cases - Sequential case execution 7. test_concurrent_clients - Multiple simultaneous connections 8. test_reserve_timeout_behavior - Auto-unreserve after timeout 9. test_failed_execution - Invalid code handling 10. test_disconnect_during_reservation - Unexpected disconnection CI Integration: - Added protocol test step to funz-calculator.yml workflow - Runs before integration tests with DEBUG logging - Tests against calculator on port 5555 --- .github/workflows/funz-calculator.yml | 9 + tests/test_funz_protocol.py | 594 ++++++++++++++++++++++++++ 2
