posix

conformance-posix

This command runs an HTTP web server that accepts POST HTTP requests to a /add endpoint. This endpoint takes arbitrary data and adds it to a file-based log.

Using in the hammer

First bring up a new log in one terminal:

export LOG_PRIVATE_KEY="PRIVATE+KEY+example.com/log/testdata+33d7b496+AeymY/SZAX0jZcJ8enZ5FY1Dz+wTML2yWSkK+9DSF3eg"
export LOG_PUBLIC_KEY="example.com/log/testdata+33d7b496+AeHTu4Q3hEIMHNqc6fASMsq3rKNx280NI+oO5xCFkkSx"
export LOG_DIR=/tmp/mylog2

# Initialize a new log
go run ./cmd/conformance/posix \
  --storage_dir=${LOG_DIR} \
  --initialise \
  --listen=:2025 \
  --v=2

In another terminal, run the hammer against the log. In this example, we're running 32 writers against the log to add 128 new leaves within 1 minute.

go run ./internal/hammer \
  --log_public_key=example.com/log/testdata+33d7b496+AeHTu4Q3hEIMHNqc6fASMsq3rKNx280NI+oO5xCFkkSx \
  --log_url=http://localhost:2025 \
  --max_read_ops=0 \
  --num_writers=32 \
  --max_write_ops=64 \
  --max_runtime=1m \
  --leaf_write_goal=128 \
  --show_ui=false

Optionally, inspect the log on the filesystem using the woodpecker tool to see the contents. Note that this reads only from the files on disk, so none of the commands above need to be running for this to work.

go run github.com/mhutchinson/woodpecker@main --custom_log_type=tiles --custom_log_url=file:///${LOG_DIR}/ --custom_log_origin=example.com/log/testdata --custom_log_vkey=${LOG_PUBLIC_KEY}
