Written by marcelpetrick on October 17, 2019

Challenge was to reconfigure a device, which has a Linux running on a TQ-board. Some files had to be adjusted.

Connect to the device:

ssh <usernam>:<ip>

(Then enter password.)

List amount of free space:

df -K .

Visual Studio testrunner still running … and stopping you from accessing DLLs for linking

Written by marcelpetrick on October 8, 2019

~~Problem~~ Challenge:
Several instances of vstest.executionengine.clr20.exe are still running, despite closing that nice Visual Studio 2015 and therefore the access to compile and link several DLLs with QtCreator is blocked.
Closing them one by one with the taskmanager is annoying.

Solution:
* CMD as admin
* $ taskkill /IM vstest.executionengine.clr20.exe /T /F
* or: $ wmic process where name=’vstest.executionengine.clr20.exe’ delete

QTest: increase the timeout duration for a test-case

Written by marcelpetrick on October 7, 2019

Set via environment variable QTEST_FUNCTION_TIMEOUT a higher timeout duration.
qputenv sets them temporary for the run of the single test case (put this at the beginning of the test case).

std::string duration("1200000"); // 1200 seconds -> 20 min
QByteArray timeoutDuration(duration.c_str(), static_cast<int>(duration.length()));
qputenv("QTEST_FUNCTION_TIMEOUT", timeoutDuration);
{ // just for checking ..
    auto result = qgetenv("QTEST_FUNCTION_TIMEOUT");
    qDebug() << "timeout set to:" << result << "ms";
}

QByteArray timeoutDuration(duration.c_str(), static_cast<int>(duration.length()));

qputenv("QTEST_FUNCTION_TIMEOUT", timeoutDuration);

{ // just for checking ..

auto result = qgetenv("QTEST_FUNCTION_TIMEOUT");

qDebug() << "timeout set to:" << result << "ms";

}

nota bene: This block has to be put before qExec is ran, so put it into the constructor of the test-suite!

Qt: libpng warning (exception) about wrong color profile (sRGB)

Written by marcelpetrick on October 1, 2019

Problem: libpng warning: iCCP: known incorrect sRGB profile

When debugging Qt applications which load some PNG as icons at startup, it could be annoying to continue with the debugger for each thrown exception.
So, let us fix them.

Invoking $ mogrify *.png in the icon directory will fix them.

How to get mogrify? Install imagemagick.
Either manually or on macOS via homebrew: $ brew install imagemagick
