Overview of changes in Sysprof 3.46.0 ===================================== * sysprof-cli is now statically linked * sysprof-agent now has a --decode option to decode symbols at the end of a capture, similar to what sysprof-cli can do. * A crash in the Elf symbol resolver has been fixed. * Translation updates Overview of changes in Sysprof 3.45.1 ===================================== This release of Sysprof is a development release and is not intended for end users. * Addition of sysprof-agent to aid in cross-container profiling and instrumentation. (Use -Dagent=(true|false) to control * Additional porting to libadwaita * Remove unused settings schemas * Nightly Flatpak builds now use org.gnome.Sysprof.Devel as the application-id * The application now uses org.gnome.Sysprof as the application-id instead of org.gnome.Sysprof3. * Icon updates * Translation updates Overview of changes in Sysprof 3.45.0 ===================================== This release of Sysprof is a development release and is not intended for end users. * Initial port to GTK 4 * A number of build configuration options where simplified and will need changing by distributions to match the new, more consistent, naming. * Libadwaita has been added as a dependency * The profiler assistant has received styling changes * libsysprof-ui had it's ABI bumped to libsysprof-ui-5 which targets GTK 4. Overview of changes in Sysprof 3.44.0 ===================================== * Translation updates Overview of changes in Sysprof 3.43.90 ====================================== * Require libunwind unless disabled manually to help ensure distributions are doing the right thing. * Add allocation leaks section to memprof. * Fix preloading of speedtrack * Fix capture of mapped path names with spaces * Translation updates Overview of changes in Sysprof 3.42.1 ===================================== * Build fixes for close()/lseek() usage * Show recording time in local time instead of UTC * Improve resolving of symbols in presence of toolbox, flatpak, and btrfs * Fix checking of paranoid state in Linux kernel * Updated translations Overview of changes in Sysprof 3.42.0 ===================================== * Much work has been done to improve path resolution of maps found within containers such as podman, toolbox, and flatpak. Overview of changes in Sysprof 3.40.1 ===================================== * Fix build system issue which caused symbols from libsysprof-capture.a to leak into the ABI of libraries consuming it. This was due to inheritance of GNU default symbol visibility. A recompilation of those libraries is necessary. Overview of changes in Sysprof 3.40.0 ===================================== * Improve symbol resolving on OSTree-based systems * Translation updates Overview of changes in Sysprof 3.39.94 ====================================== * Fix some licenses in headers. * Add API to sysprofd/libsysprof to tweak. /proc/sys/kernel/perf_event_paranoid to improve capture quality. Tooling will now always try to change this value while profiling the system and ignore upon failure. * ftruncate() before overwriting proc files. * GTK aid has been removed as it is always enabled through the use of control-fd now. * Add a new Overlay capture frame type for mapping overlays between the host and the process filesystem namespace. * Use overlays to map podman containers to overlay directories * Use overlays to map flatpak containers to overlay directories for both /app and /usr.

This allowed Sysprof to be used form GLib without circular dependencies * Various UI tweaks * Support for use as a subproject Overview of changes in Sysprof 3.36.0 ===================================== * Preload library has been moved to $libdir from $libexecdir * Build system improvements * Fix whole-system capture setting when using "Record Again" feature * New SysprofCollector interfaces for samples, marks, and logs to sit alongside allocations * Translation updates Overview of changes in Sysprof 3.35.92 ====================================== * A new profiler for tracking memory allocations within processes that are spawned by Sysprof. Select "Track Allocations" to use an LD_PRELOAD module which monitors allocations within the target process. A callgraph is provided with allocations and their stack traces. This brings the main features of the venerable "Memprof" into Sysprof. * Port Sysprof to work on RHEL 7 * Improvements to marks and counters displays * A new data frame in libsysprof-capture for memory allocations with stack traces. * sysprof-cli --merge can now be used to merge multiple syscap files together. * sysprof can now be used to open Sysprof directly to a program to execute. * Sysprof now builds with additional security protections and optimization flags such as -Bsymbolic, -Wl,-z,defs, -Wl,-z,now, and -Wl,-z,relro. * Fixes for macOS * The ELF symbol resolver is faster * sysprof-cli now properly adds supplemental information to the capture file such as decoded symbols. This makes sharing syscap files across machines easier and more reliable. * A new mmap()'d ring buffer can be shared between processes for faster data transfer to sysprof. We expect more features around this SysprofCollector interface in future releases. * A new set if icons has been provided for the collectors * Translation updates Overview of changes in Sysprof 3.35.2 ===================================== * Build and test fixes * Track changes to gdbus-codegen * Include additional pkg-config variable for access to D-Bus data * Translation updates Overview of changes in Sysprof 3.34.1 ===================================== * Process search fixes Overview of changes in Sysprof 3.34.0 ===================================== * Help fixes * Build and test fixes * Translation updates Overview of changes in Sysprof 3.33.92 ====================================== • Check for GLib 2.61.3 or newer for features used when removing deprecated API usage from GLib. • Require meson 0.50 • Translation updates Overview of changes in Sysprof 3.33.90 ====================================== • Tweak CSS styling a bit • Hide RAPL rows if no counters were discovered • Fix --no-battery in sysprof-cli • Improve parsing of /proc/mounts and /proc/pid/mountinfo • Improve support for using libsysprof from Flatpak • Symbol directories are removed from public ABI and consumers should now add directories to SysprofElfSymbolResolver directly Overview of changes in Sysprof 3.33.4 ===================================== • Build system fixes and improved backports • New network, disk, battery, and energy sources • Additional options for sysprof-cli including "syprof-cli -- command" support. • i18n is now properly initialized at startup • Improved styling • A new "duplex" graph type for read/write type visuals Overview of changes in Sysprof 3.33.3 ===================================== This release of Sysprof contains the largest amount of work since we revived the project a few years ago. We have revamped and minimized the ABI of libsysprof-ui considerably. As port of the ABI update, symbols have been changed from Sp to Sysprof to reduce chances of collisions. With these changes comes a soname bump and upgrade of the D-Bus API provided by the package. Some work has been taken to implement older versions of the sysprofd API so that older clients may continue to work. • Various build system improvements • A new libsysprof-capture-3.a capture library has been provided to allow application developers to capture data and merge into the profiler stream. • The recording and viewing API has been redesigned and improved. • Sysprof has been backported to support GTK 3.22 and GLib 2.50. • Support for passing file-descriptors has been added to allow profiling integration with GNOME Shell, GJS, and GTK profilers. • New API to allow integration with external tooling that spawns applications is provided so that environment and arguments may be modified. • A new re-record feature has been added. • The capture format can now store log messages, metadata, and file content. • A new org.gnome.Sysprof3 daemon has been added, which is written using GDBus instead of libsystemd. This may improve portability to some distributions. • The portability of Sysprof to non-Linux systems has been improved, however many recording features are still not available on non-Linux platforms. • A new org.gnome.Sysprof3.Profiler XML D-Bus interface is provided for tooling that wants to export Sysprof content via D-Bus. • Various new capture sources have been provided. • sysprofd also implements a compat org.gnome.Sysprof2 D-Bus end-point for older clients. • Translation updates Happy Profiling, -- Christian
