プロジェクトの歴史

The official repository was created in 2014. The README says uftrace was heavily inspired by the Linux kernel ftrace framework, and that the name combines user and ftrace.

The project began with compiler-supported function tracing but later added dynamic tracing. The README describes that shift explicitly: it initially supported tracing with compiler support, then gained the ability to trace without recompilation by analyzing function prologues and dynamically patching instructions.

Recent releases show the tool continuing to broaden language, architecture, and analysis support. The NEWS file records Python tracing in v0.14, RISC-V support in v0.15, separate debug-file support in v0.16, watchpoints in v0.17, filter-condition work in v0.18, and latency percentile scripting plus Chrome dump timestamp improvements in v0.19.

採用の歴史

uftrace's adoption niche is developers and performance investigators who want call-graph-level tracing from a command-line tool, especially on Linux. Its package-manager footprint in this batch includes Homebrew, Debian, Nix, Ubuntu, and openSUSE, showing cross-distribution demand beyond its upstream GitHub audience.

The project also maintains package-awareness in its README by displaying Repology packaging status, a small signal that upstream expects distribution packages to be a major discovery and installation path.

使われ方

Users can run uftrace live against a program, or record first and replay/report/graph/dump/analyze the saved `uftrace.data` directory. The command set includes `record`, `replay`, `report`, `live`, `info`, `dump`, `recv`, `graph`, `script`, and `tui`.

The tracing modes cover compiler instrumentation such as `-pg`, `-finstrument-functions`, and `-fpatchable-function-entry`, dynamic patching with `-P.`, PLT/library call tracing, Python tracing, kernel tracing through Linux ftrace, Linux event tracing, perf_event scheduling and PMU information, and SystemTap SDT user events.

uftrace also supports filters, function arguments and return values, Chrome trace viewer output, flame graphs, graphviz and mermaid call graphs, source-line information, and scripts through Python/LuaJIT APIs.

パッケージ好きにとっての重要性

For package nerds, uftrace sits in the sweet spot between `strace`, profilers, kernel ftrace, and language-specific tracers. It is a single CLI that exposes a deep stack of optional capabilities, so distribution builds and optional dependencies materially affect what the installed package can do.

It is also notable because it brings kernel-tracing ideas to userspace debugging workflows while remaining scriptable and inspectable from the shell. That makes it attractive in package-manager ecosystems where developers want performance tools available with one install command.
