- Add web server integration to cluster_demo.sh script - Configure web server port (8090) - Update build_if_needed() to check for toastyfs_web binary - Add get_web_binary() function - Start web server after chunk servers - Update status display to show web server - Update help text to show HTTP interface - Fix bug in web/main.c where --local-port incorrectly set upstream_port instead of local_port The cluster demo now starts a full cluster with: - Metadata server on port 8080 (ToastyFS protocol) - N chunk servers starting from port 8081 - Web server on port 8090 (HTTP interface)
Scripts
This directory contains utility scripts for ToastyFS development and testing.
Cluster Demo Script
The cluster_demo.sh script allows you to easily spawn and manage a ToastyFS cluster for demo and testing purposes.
Usage
# Start a cluster with 3 chunk servers (default)
./scripts/cluster_demo.sh start
# Start a cluster with a custom number of chunk servers
./scripts/cluster_demo.sh start 5
# Check cluster status
./scripts/cluster_demo.sh status
# Stop the cluster
./scripts/cluster_demo.sh stop
# Clean all cluster data and logs
./scripts/cluster_demo.sh clean
What it does
The script:
- Builds ToastyFS if needed
- Starts one metadata server (leader) on port 8080
- Starts the specified number of chunk servers on ports 8081, 8082, etc.
- Stores all process IDs for easy management
- Captures logs to
cluster_logs/directory - Stores data in
cluster_data/directory
All servers run in the background, making it easy to test the cluster with client applications.
Branch Coverage Measurement
Prerequisites
The HTML report generation requires lcov:
sudo apt-get install lcov
Usage
Quick text summary (5 second simulation)
make coverage-report
HTML report with branch details (5 second simulation)
make coverage-html
Custom duration
./scripts/measure_coverage.sh 10 # 10 second run, text output
./scripts/measure_coverage.sh 10 --html # 10 second run, HTML output
What gets measured
The coverage tool:
- Builds the test binary with coverage instrumentation (
--coverageflag) - Runs the random simulation for the specified duration
- Generates reports showing which branches were executed
Output
Text report: Shows per-file and total branch coverage percentages
HTML report: Interactive report generated by lcov/genhtml showing:
- Overall coverage summary
- Per-file coverage breakdown
- Source code with execution counts
- Branch coverage details
The HTML report is generated in coverage_report/index.html
