Bug 651682 – x11-misc/qt5ct: suppress debug messages

• Status: RESOLVED CANTFIX
• Product: Gentoo Linux

[Description Dmitriy Dyomin 2018-03-27 10:00:28 UTC]

Currently, using x11-misc/qt5ct produces the following output:

qt5ct: using qt5ct plugin

It happens from qCDebug() calls in the package. Qt allows customization of log messages via environment variable QT_LOGGING_RULES.


Reproducible: Always

Steps to Reproduce:
1. install x11-misc/qt5ct
2. reload profile (source /etc/profile)
3. start any qt5 application
Actual Results:  
unwanted message "qt5ct: using qt5ct plugin" is printed to console

Expected Results:  
no output

qt5ct-0.35-r1.ebuild adds appropriate QT_LOGGING_RULES to /etc/env.d/98qt5ct

Please attach a unified diff (diff -u) of the changes you did to the ebuild.

OK, will review and fix this tomorrow.

Unfortunately the fix for this bug isn't possible atm.
System-wide QT_LOGGING_RULES doesn't stack across multiple files.
Also system-wide QT_LOGGING_RULES can be mistakenly deactivated
if a user defines this variable himself.

Current QT_LOGGING_RULES mechanism is too unreliable.
