Description Elliott Sales de Andrade 2011-06-27 01:48:03 UTC

Description of problem:
If you interrupt doxygen while it's creating the PNG call graphs, then you get the PNG output to the console in binary form.

Not only is it a bunch of gibberish, it sometimes messes with the console settings for fonts and colours and such. Additionally, since they're not immediate children of the shell, you can't interrupt them with another Ctrl+C.

It seems like the main doxygen process closes, but doesn't cancel any of the graph processes, which spew to console, since their parent is gone.

Version-Release number of selected component (if applicable):
doxygen-1.7.4-1.fc14.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Start a Doxyfile with call graphs enabled.
2. Run doxygen.
3. Hit Ctrl+C when it gets to the graph creation step.

Actual results:
The binary PNG data is printed on the console.

Expected results:
doxygen should exit without any extraneous output.

Comment 1 Fedora End Of Life 2012-08-16 16:28:56 UTC

This message is a notice that Fedora 14 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 14. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained.  At this time, all open bugs with a Fedora 'version'
of '14' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this 
occurring, but we forgot to do that. A thousand apologies.)

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, feel free to reopen 
this bug and simply change the 'version' to a later Fedora version.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we were unable to fix it before Fedora 14 reached end of life. If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora, you are encouraged to click on 
"Clone This Bug" (top right of this page) and open it against that 
version of Fedora.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Comment 2 Elliott Sales de Andrade 2012-08-16 22:28:04 UTC

Can still reproduce on Fedora 17 with doxygen-1.8.1.1-3.fc17.x86_64.
