#8007: [app_server] fully unresponsive when resizing window of big textfile ----------------------------------+---------------------------- Reporter: ttcoder | Owner: axeld Type: bug | Status: new Priority: normal | Milestone: R1 Component: Servers/app_server | Version: R1/Development Resolution: | Keywords: Blocked By: | Blocking: Has a Patch: 0 | Platform: All ----------------------------------+---------------------------- Comment (by bonefish): Replying to [comment:3 Pete]: > Is it possible the scheduler isn't time-slicing properly? I would rather suspect a locking related issue. There are debugging tools to analyze such a situation. The `scheduling_recorder` command line tool records scheduling data while it runs (only parameter in this case would be the output file into which it writes the data). It should be started immediately before running the test (i.e. the resizing itself) and stopped (Ctrl-C) when done. The resulting file is then passed as command line argument to `DebugAnalyzer`, a GUI app that allows to analyze various aspects of scheduling and locking behavior. I haven't really used the tools for a long time. I quickly tested them while working in my signals branch, since I reworked some related kernel code and they seemed to work fine. Neither tool is in the default image. -- Ticket URL: <http://dev.haiku-os.org/ticket/8007#comment:5> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
