Git commit ac59cc7e007a3ef73a07f3d31d4a9516fd5f56f5 by Martin T. H. Sandsmark.
Committed on 16/07/2018 at 11:46.
Pushed by sandsmark into branch 'master'.
Fix hang on a lot of output from a program
Summary:
There is a bug in the Qt glib event loop leading to timers never being
able to deliver signals.
Work around this by disabling the glib event loop.

Running the following program within konsole:
#include
int
main()
{
for (int i = 0; i < 1; i++)
{
fprintf (stderr, "foo %d\n", i);
}
}
leads to a freeze - not single message is printed - no reaction on
return. Only after a long time (30 seconds) something happens.
If I run the same program in an xterm, the messages are scrolling
through, as I would expect from that kind of output.

I also see this. Using Kubuntu 16.04 here. For example, if GStreamer is installed, when I run this in konsole: GST_DEBUG=2,*src*:9 gst-launch-1.0 fakesrc ! fakesink silent=false then output will eventually no longer be printed. For a while, I can press the return key to manually "advance" the log output (perhaps this flushes something inside konsole?), but eventually, it reaches a point where the tab is completely frozen - I can scroll back, and copy text, but keyboard input no longer does anything, and the output is still. The only thing I can do then is to close that tab. This is highly annoying when debugging code, because sometimes, there can be lots of log output, which in turn sometimes triggers this bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/840708 Title: Konsole only redraws the terminal if the mouse is moving.

In my observation, 'hang/freeze' is not quite accurate. Konsole will
update its display, but not in a smooth and continuous way. Periodicaly,
the display will pause for a few seconds , then it resumes with contents
not continuous with previous one. And konsole will take high percent of
CPU, 80% in my case.
That also applies to stdout.

I see this kind of behaviour too, but then specifically with very long
lines (a sipXproxy.log). The lines span about 5-6 rows of my very wide
konsole window. The same file scrolls very quickly in xterm.
It seems that konsole is taking up the entiry CPU and given the modern
cgroup configuration in ubuntu 12.04, the remaining cpu doesn't get used
for other windows... :-(

[Bug 840708] [NEW] Konsole only redraws the terminal if the mouse is moving.
Public bug reported: Version: 2.7 (using KDE 4.7.0) OS:Linux If you have text constantly scrolling down a terminal window in Konsole, the screen only redraws the scrolling text while there is mouse movement. If you stop moving the mouse, the text stops. On another machine that I tried this on, it is less pronounced, but still happens off and on. On that machine, it will stop if you click outside the window and only start again after moving the mouse over Konsole's window. Reproducible: Always Steps to Reproduce: I have written a small c program that displays integers in sequence in an infinite loop. You can seen the problem if you compile this program and run the a.out in a konsole window. Actual Results: The text freezes and the Konsole window is not redrawn until you move the mouse. Expected Results: Constantly scrolling text with no interuption. OS: Linux (x86_64) release 2.6.38-11-generic Compiler: gcc I'm using Kubuntu 11.04 with KDE 4.7.0 ** Affects: kde-baseapps Importance: Unknown Status: Unknown ** Affects: konsole (Ubuntu) Importance: Undecided Status: New ** Bug watch added: KDE Bug Tracking System #281299 http://bugs.kde.org/show_bug.cgi?id=281299 ** Also affects: kde-baseapps via http://bugs.kde.org/show_bug.cgi?id=281299 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/840708 Title: Konsole only redraws the terminal if the mouse is moving.
