Seer Change Log

[2.5beta] - 2024-XX-XX

  • Starting the 2.5 development cycle.

[2.4] - 2024-03-18

  • Changed main icon to a more license friendly one. All icons are now GPLv3, CC3.0, or CC4.0
  • Fixed string compares for breakpoint conditions (#184)
  • Added '--bs' command line option to specify a breakpoint at a source.cpp:lineno
  • Fixed long tooltips text by restricting them to 100 characters. (#189) The text in the various viewing dialogs is still the full length. The 100 limit probably needs to be configurable.
  • Added register profiles to show only interesting/relevant registers.
  • Added UTF-8,16,32 support in the Memory Visualizer.
  • Added an internal "dark" and "light" theme via the View->Style menu.
  • Added option to open the current source file in an external editor.
  • Fixed saving of RR parameters in config dialog.
  • Sped up some visualization views.

[2.3] - 2023-11-19

  • In the margins of the source windows, allow CTRL+DoubleClick to do a quick RunToLine or RunToAddress.
  • Add --gdb-program and --gdb-arguments to command line to override settings from Seer's config.
  • Fixed a rare bug with blank lines from gdb causing a segv in GdbMonitor.
  • Fixed bug specifying path to "rr" debugger.
  • Add option to reload source file if it changes.
  • Tighten up the layout by removing some needless whitespace.
  • Move gdb messages to a tab in the breakpoints window.
    • Options to raise on every message, never, or important messages.
  • Add C++ level (11 or 17) depending on qt5 or qt6 compile.
  • Fixed up column resizing for the Variable logger (#173)
  • Use monspace font, where it makes sense (#175)
  • Allow copy to clipboard (#176)
  • Fixed hovering a variable name and value (#179)
  • Add nested struct viewing in "locals", "arguments", "logger", and "tracker" tabs. (#180)

[2.2] - 2023-09-07

  • Fixed infinite loop when starting with RR mode.
  • Reworked RR mode to directly run 'rr replay'. No need to start a 'rr server' and connect to it. https://github.com/epasveer/seer/wiki/RR-and-Seer
  • Fixed Source handling in source browser. Qt5 mode was broken. Qt6 works. Directory paths need a tailing "/*"

[2.1] - 2023-08-23

  • Add Execution dialog to record breakpoint events. This solves the problem of too many break/error dialogs to "swat away" as the program is debugged.
  • Add a method to add/change gdb commands to execute when a breakpoint (breakpoint, watchpoint, catchpoint) is reached.
  • Add a method to add/change a breakpoint's condition command.
  • Add a method to add/change a breakpoint's ignore count.
  • Add a method to add/change a breakpoint's command list.
  • Debug dialog for "attach" mode now detects executable name and path from /proc//exe.
  • Commandline for "attach" mode now detects executable name and path from /proc//exe.

[2.0] - 2023-03-06

[1.17] - 2023-04-23

[1.16] - 2023-04-07

  • Add pid to main window and console title bars.
  • The Pending flag is automatically supplied to the breakpoint function in the Debug dialog for the Run mode. Some apps use deferred loading of code with dlopen().
  • Fixed bug when restoring from project file with 'start' mode.
  • ADA: Improve visualizers for Ada arrays. "(system.address) 0x7fffffffcf10"
  • ADA: Add Ada task browser.
  • ADA: Add Ada specific catchpoints.
  • ADA: Add Ada exception brower.

[1.15] - 2023-03-04

  • Revamp Debug dialog. Move debug modes into "tabs".
  • Add "help" icon to each debug mode in Debug dialog.
  • Add 'pre' and 'post' gdb commands that can be executed just before and just after the program is loaded into gdb.

    • Function. The view shows all assembly in the function the $PC is in.
    • Length. The view shows N bytes of assembly after the $PC. Used for code that is pure assembly or has no debug information.
  • Minor fixes when debugging corefiles.
  • Fixed breakpoints with conditional statements.
  • Fixed up icons and Debian "copyright" file for Debian Intent-To-Package.
  • Double-clicking on a breakpoint in the source window will delete it. Previously it would disable it.

  • Hide certains buttons (Run, Start, ...) depending on Debug mode (run, attach, connect, etc...)
  • Save state of tabs (tab order and current tab). So next session will get them.
