Provides start/stop/status/restart/clean commands to manage a local
ToastyFS cluster. Nodes listen on 127.0.0.1:8001-8003 with the HTTP
proxy on 127.0.0.1:3000. Each node gets its own chunk storage directory
under cluster-data/. Logs and PID files are stored there as well.

Introduce a Makefile that builds libtoastyfs.a and libtoastyfs.so from the
client-side sources (client, tcp, byte_queue, message, basic) so external
programs can link against the ToastyFS client API in include/toastyfs.h.
Add cluster.sh, a convenience script that manages a local 3-node cluster
by spawning toastyfs server processes on ports 8081-8083. Sub-commands:
up, down, status, logs, and "run <source.c>" which builds the library,
compiles the source against it, starts the cluster, runs the binary, and
tears everything down.
Add examples/example.c demonstrating synchronous PUT, GET, DELETE, and a
NOT_FOUND verification.
Fix a stack overflow in the MAIN_SERVER entry point: ServerState is ~40 MB
(MetaStore holds 4096 ObjectMeta entries) and was declared on the stack.
Heap-allocate it instead.

Add a Dockerfile and docker-compose.yml that spin up a 3-node ToastyFS
server cluster on a private bridge network with ports 8081-8083 exposed
on the host. Include cluster.sh as a convenience wrapper (up/down/status/
logs/run) — the "run" sub-command builds the library, compiles a user-
supplied C source against it, starts the cluster, and executes the binary.
Add examples/example.c demonstrating synchronous PUT, GET, DELETE, and a
NOT_FOUND verification.

Adds build_coverage.sh script that:
- Builds the simulation with GCC branch coverage instrumentation
- Supports --report flag to run simulation and generate lcov HTML report
- Uses 60 second timeout with SIGINT for graceful shutdown
Also adds SIGINT handler to simulation to exit cleanly and flush coverage data.
This script provides a convenient way to spawn and manage a ToastyFS cluster
for demo and testing purposes. Features include:
- Start a cluster with configurable number of chunk servers
- Automatic building if binary is not present
- Process management with PID tracking
- Status checking for all cluster nodes
- Easy cleanup of all cluster processes
- Separate log files for each server component
- Colorized output for better readability
Usage:
./scripts/cluster_demo.sh start [num_servers] - Start cluster
./scripts/cluster_demo.sh stop - Stop cluster
./scripts/cluster_demo.sh status - Show status
./scripts/cluster_demo.sh clean - Clean data/logs
Enhance the branch coverage measurement tool with HTML report generation
that shows exactly which branches were taken during simulation execution.
Changes:
- Add generate_coverage_html.sh script to create interactive HTML reports
- Update measure_coverage.sh with --html flag to generate reports
- Add *.gcov, *.gcda, *.gcno to .gitignore
- HTML reports show:
- Overall coverage summary with visual progress bars
- Per-file coverage breakdown with clickable links
- Source code view with color-coded branch coverage
- Green highlight: branches taken
- Red highlight: branches not taken
- Branch execution counts and percentages
Usage:
./measure_coverage.sh [duration] --html
The HTML report is generated in coverage_report/index.html and can be
viewed in any web browser. Each source file links to a detailed view
showing which specific branches were executed.
- Add CLIENT_CFILES and CLIENT_OFILES variables to Makefile
- Add rules to build object files and create static library
- Include libmousefs_client.a in the 'all' target
- Update clean target to remove library and object files
- Update .gitignore to ignore *.o and *.a build artifacts
The library includes: client.c, basic.c, tcp.c, message.c
