v0.1.8

What's New

Append Mode (--append / -a)

• Continue recording to the most recent profile for a process instead of creating a new file
• When appending, TUI shows historical data immediately
• Chart can pan back to see data from previous recording sessions
• Timestamps continue seamlessly from where the previous recording ended

Usage

# First recording
rsprof -p <PID>

# Continue recording to the same file later
rsprof -p <PID> --append

# Or specify a specific file
rsprof -p <PID> -o profile.db --append

v0.1.7

What's Changed

• Switch to aggregated callsite stats model for CPU/heap profiling
• Add shorten_function_name() to display Type::method or just function
• Strip hash suffix before shortening for cleaner display
• Add CPU test patterns: sawtooth, square wave, varying depths
• Add heap test patterns: sawtooth, square wave, varying depths

Full Changelog: v0.1.6...v0.1.7

rsprof v0.1.6

Highlights:\n- Remove self-profile support to keep publishable dependencies clean.

rsprof v0.1.5

Highlights:\n- Remove eBPF heap backend; heap profiling now relies on rsprof-trace shared memory.\n- Simplify heap sampler paths and dependencies.

v0.1.3

• Fix fmt/clippy warnings\n- Remove stale example entry\n- TUI table sorting and selection stability\n- Version bump to 0.1.3

v0.1.2

• Add README screenshots\n- TUI table sorting with clickable headers and stable selection\n- Reduce live TUI DB polling and refresh heap chart cache\n- Bump version to 0.1.2

v0.1.1

What's Changed

Bug Fixes

• Fixed heap sample over-counting: Heap stats were being recorded on every loop iteration (every 10ms) with cumulative values, causing massive inflation. Now recorded once per checkpoint.
• Fixed rsprof_trace filtering: The TUI had a duplicate SKIP_FUNCTION_PATTERNS that was missing rsprof_trace::, causing profiler internals to appear in results.
• Fixed ASLR offset calculation: Changed from using executable segment to first segment for correct symbol resolution.

Improvements

• Better function name formatting: Trait impls like <Type as Trait>::method now display as module::Type::method
• Utility function attribution: clone, fmt, to_string, etc. now attribute allocations to their callers instead of showing struct field lines
• Sort heap by live bytes: Heap query now sorts by live DESC to surface memory leaks first
• Frame pointers for all crates: Added .cargo/config.toml to ensure frame pointers are enabled for accurate stack traces
