Overview of changes in Sysprof 3.31.91 ====================================== * Translation updates Overview of changes in Sysprof 3.31.91 ====================================== * Handle cancellation during profiler startup more gracefully. Overview of changes in Sysprof 3.31.90 ====================================== * A new memory source for basic memory statistics. This is meant for overview only, not precise details. * Fix a small memory leak. * Allow disabling memory/cpu sources from sysprof-cli. * CSS styling updates. * Updated icon for GNOME 3.32 icon initiative. * The line visualizer can auto-discover Y axis range. * Build system improvements. * Updated translations. Overview of changes in Sysprof 3.31.1 ===================================== * Remove app-menu in favor of window-menu, following GNOME design guidelines for 3.32. * Fixes for i18n/l10n. * Build fixes to avoid use of non-portable __WORDSIZE. Translations: * Swedish, Indonesian, Hungarian, Czech, Polish, Brazilian Portuguese Overview of changes in Sysprof 3.30.1 ===================================== * Various compilation fixes for alternative platforms, compilers, and toolchains. * Backport model filter fixes from libdazzle. Translations: * Swedish, Hungarian, Brazilian Portuguese Overview of changes in Sysprof 3.30.0 ===================================== * Fix incorrect free func for GPtrArray * Various build system improvements * ENABLE_POLKIT is now repsected in the kallsyms support * suggested-action fixes for CSS Translations: * Swedish, Spanish, Brazilian Portuguese, Italian, and German Overview of changes in Sysprof 3.29.3 ===================================== * Experimental tracking of various drm events (vblank and CRTC/MSC) * Drawing code now uses double instead of float for additional precision * CLOCK_MONOTONIC is now the preferred clock * A new capture type of "mark" has been added to the capture format. It supports an event name with a duration >= 0. We expect to integrate this with a timechart in a future release. * Various counters are automatically detected and displayed when opening a capture file. * Various cleanups to libsysprof-capture-2.a for re-usability * A new in-tree tool "sysprof-cat" which can join multiple capture files together gracefully. * Fix a number of situations where cpu/pid were crossed. Translations: * Indonesian, German, Italian, Czech, Polish Overview of changes in Sysprof 3.28.0 ===================================== * SpCaptureWriter now pre-initializes the scratch buffer to zero to pacify valgrind. Translations: * Swedish Overview of changes in Sysprof 3.27.92 ====================================== Translations: * Serbian, German, Finnish, Spanish, Hungarian Overview of changes in Sysprof 3.27.91 ====================================== * Sysprof now exclusively uses the meson build system. * Improvements to the process filtering model used in the profiler popover. * More tests for utility helpers. * Some code was relicensed to LGPLv2.1+ to extend it's reusability. * A new libsysprof-capture-2.a static library is installed to allow external tooling to read and write the capture format. We expect tooling such as GJS to use this in the future. * A new kallsyms tokenizer was added. * If we fail to parse kallsyms as the effective user, we now query the sysprofd daemon to access and parse those symbols for us as root. This requires polkit authorization on the DBus connection just like our elevated perf_event_open() helper. * Now that we have to deal with overlapping kernel and user-space memory, Sysprof tries harder to check the current perf context. New API was added to symbol resolvers to facilitate this. Translations: * Czech, German, Polish Overview of changes in Sysprof 3.26.0 ===================================== Sysprof 3.26.0 is identical to 3.25.92 with version numbers updated. Overview of changes in Sysprof 3.25.92 ====================================== Changes since 3.24.0 * Additional help topics * Fix for a potential divide-by-zero when generating callgraphs * Alignment attributes to allow building on armel/armhf/mipsel * About dialog is now modal * Each new Sysprof window gets its own window group Note to packagers: * We will drop autotools after 3.26 and complete our switch to Meson. Translations: * Indonesian, Spanish, Slovak, Friulian, Czech, Polish, Brazilian Portuguese Thanks to all of our contributors Overview of changes in Sysprof 3.24.0 ===================================== Changes since 3.23.92 * Use gtk_show_uri_on_window() to improve help window placement on Wayland.

This should allow some degree of profiling container-based applications and still resolve symbols on the host. Builder does this now when profiling Flatpak-based applications. Translations: * Finnish, Serbian Overview of changes in Sysprof 3.23.90 ====================================== Changes since 3.22.3 * Build system support for Meson. This may become the preferred build system for 3.26 based on feedback from distributions. * Appdata support has been added * Desktop file can be translated Translations: * Brazilian Portuguese, Polish, Czech, Slovak, and Spanish. Overview of changes in Sysprof 3.22.3 ===================================== Changes since 3.22.2 * Fix expansion of function text in callgraph. * Fix jump-to-function in callees list. * Disable record button while generating callgraph profile. * Ensure sysprof icons are available form libsysprof-ui-2. * sysprof-cli requires --force to overwrite previous capture. [Hubert Figuière] * Reduce code duplication in capture frame initialization. [Vito Caputo] Translations: * Brazilian Portuguese and Polish translations were updated. [Enrico Nicoletto, Piotr Drąg] Overview of changes in Sysprof 3.22.2 ===================================== Changes since 3.22.1 * ftruncate() when creating a capture in case we overwrite a previous capture file. This ensures we don't leave junk at the end of the capture. * Handle EAGAIN when writin the opportunistic end-time header. * Capture cursor should short circuit when no read delegate was found. Translations: * Czech and Slovak translations were updated. Overview of changes in Sysprof 3.22.1 ===================================== Changes since 3.22.0 * A new data source called "hostinfo" has been added. It records various CPU datapoints as "counters" in the sysprof capture. * A new visualizers abstraction has been added so that we can start providing new ways to look at profiler data. * A CPU visualizer has been added which renders datapoints recorded from the hostinfo data source. * Selecting ranges of the visualizer will update the callgraph limiting stacktrace samples, to the given time range. * Missing headers are now installed which may be needed by applications using libsysprof-ui. * A keyboard shortcuts dialog has been added. * A theme manager has been added to allow us to provide custom CSS for various themes. Currently, we have additional styling added for Adwaita and Adwaita-dark. Thanks again to all of our translators Overview of changes in Sysprof 3.22.0 ===================================== Sysprof 3.22.0 is here, which contains mostly just translation improvements since 3.21.91. Thanks to our translators! Marek Černocký, Matej Urbančič, Jiri Grönroos Overview of changes in Sysprof 3.21.91 ====================================== Sysprof 3.21.91 is here with a few changes as we stabilize for 3.22. * Allow collapsing the callgraph tree with Left arrow. * Add a full barrier before writing data_tail as suggested by Perf kernel documentation. (Ray Strode) * Support for additional architectures has been enabled by the use of C11 atomics. * Require -std=gnu11 for stdatomic.h * Correct gettext domain for translation files (Kalev Lember) If you have fun and interesting architectures, please give them a try! Overview of changes in Sysprof 3.21.90 ====================================== Sysprof 3.21.90 is our first release while we prepare things for the 3.22.0 release of GNOME. Thanks to everyone who contributed to this release! Build System Improvements * Sysprof now supports an --enable-sysprofd configure option to ensure the systemd/dbus service is installed. (Jussi Kukkonen) * sysprof-ui-2.pc is only installed if the Gtk UI is installed. * Build fixes for polkit integration. Bugs Fixed * Workaround for systems without memfd * Support older Linux/perf implementations * Architecture improvements for ARM * Fix use of U64_TO_POINTER (Jussi Kukkonen) * Hide info bar when starting to record (Tim Bäder) * Expand cursor row on Right in callgraph (Tim Bäder) * Elf symbol resolver now recognizes more GNOME platform libraries. * Sysprofd integration now pings the service before considering it available for use. * Correctness improvements for capture reader and writer. New and Updated Translations * Swedish (Anders Jonsson) * Hungarian (Balázs Meskó, Gabor Kelemen) * German (Christian Kirbach) * Spanish (Daniel Mustieles) * Slovak (Dušan Kazik) * Czech (Marek Černocký) * Polish (Piotr Drąg) * Brazilian Portuguese (Rafael Fontenelle) * Portuguese (Tiago Santos) * Serbian (Мирослав Николић) Overview of changes in Sysprof 3.20.0 ===================================== Sysprof 3.20.0 is a major rewrite of the sysprof internals. * The GTK+ user interface has been ported to GTK+ 3, and includes the use of modern GTK+ patterns, including GtkHeaderBar. * A new library, libsysprof-2 has been created, which contains the internals for implementing a Linux perf-based profiler. * A new library, libsysprof-ui-2 has been created, which can be used by IDEs to provide profiling capabilities. GNOME Builder is expected to take advantage of this. * Sysprof uses a new binary capture format, to allow for collecting more types of data than simply Perf callchain information. * Data collection sources have been abstracted, allowing for new types of data collection to occur. Additionally, it is now possible to port Sysprof to other operating systems if contributors are found to implement those features. As before, Sysprof is currently supported on Linux, where the perf_event_open syscall is available. * The sysprof capture format supports information from JITd languages. Patches to Gjs (GNOME's wrapper around mozjs24) exist that can export JIT information from the JavaScript engine. * Sysprof now supports launching an application as part of the profiling process. * Sysprof can attach to one-or-more existing processes to collect profiling information. This still uses the Linux perf infrastructure, which means sampling is still performed. * The user interface provides a stopwatch for the amount of time that has elapsed since recording started. If you find that the sysprof UI shows up in your capture, we suggest using sysprof-cli to collect samples. * The Sysprof UI provides tags next to common GNOME libraries used in the GNOME stack to allow users to quickly identify libraries that may not have fully-qualified symbol names. * The binutils based demanger has been removed in favor of abi::__cxx_demangle() function. This fixes modern C++ demangling and vastly simplifies the Sysprof codebase. However, it does require a C++ compiler and linker to build Sysprof. Applications using libsysprof-2 and libsysprof-ui-2 do not require a C++ compiler. * Sysprof now provides a D-Bus service, sysprofd, which can perform elevated perf_event_open syscalls on behalf of the user interface after appropriate authorization. Polkit is used to perform the authorization. This service requires sd-bus from systemd 222 and newer. If you choose not to use this service, or do not have systemd on your system, you will have to perform system-wide captures as root, either via the UI, or via sysprof-cli. * sysprof-cli now supports executing a command with the -c option. * A new mimetype for *.syscap is installed to allow opening capture files from Nautilus or other file-managers. * The sysprof artwork has been updated. * Sysprof can now be translated using GNOME's i18n and l10n infrastructure. * Sysprof now comes with a modest help manual which can be viewed with the Yelp documentation browser. * New code in sysprof has been licensed under the GPLv3 or newer. Translations * Brazilian Portuguese by Rafael Fontenelle * German by Mario Blättermann * Polish by Piotr Drąg * Serbian by Мирослав Николић It is worth noting that Sysprof is still a sampling based profiler. However, it should now be possible to extend sysprof to support tracing via callgrind. If you are interested in helping on this effort, please let us know and we can help you get started.
