Full Changelog: v0.12.0-rc...v0.12.0-experimental

v0.11.1

⚠️ This release has an issue with allocation profiling on arm64 platforms. This can be disabled by using the cpu_only preset.

ddprof --preset cpu_only /app/my_app

What's Changed

• Enable automatic releasing to GITHub
• JITDump support
  This enables ddprof to profiles new languages.
• Fix crash when using custom stack (example: Fibers)
• Fix tag validation

v0.10.1

Installation changes

We now ship 2 binaries (down from 4). The binaries are compatible with both musl and glibc (including older libc versions).

What's Changed

• Allocation profiling - instrument forks
• Universal binary - remove dependency on libc
  This allows compatibility with older libc (like centos 7)
• Formalize tracepoint grammar
• Add build-id to mapping information
• Switch user if failing to read /proc/<pid>/maps
• Changes in instrumentation mechanisms
  Periodically check for new loaded libraries (avoids missing libraries loaded with dlopen)
  Use GOT override instead of symbol interposition
• Add information on lost events
  When ring buffer is full we flag them as "lost events".
• Use jemalloc as default allocator
  Improves performances of musl builds

v0.9.3

What's Changed

Fix allocation profiling in wrapper mode

Full Changelog: v0.9.2...v0.9.3

Changes since 0.8.1

• Allocation profiling
  Library mode and wrapper mode have an option to instrument allocations with low overhead.
  Limitation: This only works for dynamically linked allocators (example: standard allocator) and does not follow forks. If you are concerned by these limitations, please reach out with your requirements.
• Samples are labeled with PID / TID
• Preset option : adds defined presets to simplify configuration of the profiler (cpu_only, alloc_only)
• Catch kernel activity (when permissions allow it)
• Several improvements to unwinding
• Alpine musl (built on 3.16)

[rc] v0.9.2

Issues

Allocation profiling does not trigger if the library is not found (fixed in 0.9.3)

What's Changed

• Allocation profiling
  Library mode and wrapper mode have an option to instrument allocations with low overhead.
  Limitation: This only works for dynamically linked allocators (example: standard allocator). Please reach out if you are using statically linked allocators and want a solution for allocation profiling.
• Samples are labeled with PID / TID
• Preset option : adds defined presets to simplify configuration of the profiler
• Catch kernel activity (when permissions allow it)
• Several improvements to unwinding
• Alpine musl (built on 3.16)

v0.8.1

What's Changed

New features

• Library mode
  Deliver profiler as static and shared libraries. DDProf is embedded in the library.
  The library daemonizes ddprof. Check out our internal documentation here.
• ARM support

Updates

• Remove usage of libdwfl internals
• Free inconsistent dwfl modules
  We can come into situations where DSOs don't match the dwfl objects.
  In this situation we can free all of the PID objects to ensure we will
  reload all DSOs and all dwfl objects at the next sample
• Minor fixes for global mode
• Multiple updates in build system
  Support ninja, import llvm to a third party directory, compile in c++20,
  setup third parties during configure step.
• Ensure we export the data gathered at the end of the process's lifetime
  This also ensure we export data for short lived processes
• Improved management of signals
  SIGTERM and SIGINT now properly end the application

v0.7.0

Overview

First public release of the Datadog Native Profiler for Linux! This is a low-overhead CPU-time profiler for x86_64-based applications running on Linux. It is most useful for analyzing applications written in compiled languages like C, C++, and Rust, but it may be useful for other languages and even pre-build services.

Please check out our public documentation here.

You can also check out our README for more information.
