[Qt-creator] QtCreator 4.6 - constant, high CPU usage

[Jakub Narolewski]

Thank you for the link to the Jira task, Alessandro.

I now believe I can reproduce this 100% of the time.
I have added a comment in the Jira.

Hi Jakub,

there were reports about Qt Creator occupying one CPU core for no obvious 
reason.

Here is the Jira task:
https://bugreports.qt.io/browse/QTCREATORBUG-19458
It would be great to gather more information about it.

Thank You,
Alessandro

Betreff: [Qt-creator] QtCreator 4.6 - constant, high CPU usage 
 

Hello :]

I'm having a weird problem with newest Creator update.
QtC seems to spin some heavy-duty thread on one of CPU cores on all my machines.
On my six cored AMD CPU I see it taking 16% of total processing power [as 
reported by Windows' Task Manager].
I notice it every time due to my not-so-quiet fans :P

This starts at seemingly random times; sometimes during cpp/QML code editing, 
sometimes when QtC is minimized.
When it starts there is 50/50 chance it won't stop on its own and only closing 
the application helps.

I remember seeing something very similar in versions 4.5.x when I had clang 
refactoring plugin enabled in Plugins menu.
In version 4.6 I can't seem to find this plugin in the list.

This happens in QtCreator installed with MaintenanceTool.
It reports itself as:

Based on Qt 5.10.1 (MSVC 2015, 32 bit)
Built on Mar 27 2018 15:05:08
>From revision 3ac2aa7bb5

I have this problem on up-to-date versions of Windows 7 x64 and Windows 10 x64 
on two different workstations.
Have someone seen something like this lately? Maybe it has an already opened 
issue?

[Qt-creator] Lightbulb everywhere

[Jason H]

I'm trying out the new clazy and fixit support in 4.6.

I have a few observations, I'm hoping people can suggest how to fix them. (No 
pun intended).
Most of these are not QtCreator's fault, but some are. The question for those 
are how does QtC help manage them?

1. Header guards are not detected, and when I fit-insert them, they hardcode 
the FULL path.
2. I have lightbulbs everywhere that don't do anything when I click on them. 
(see attached, 2 pics)
3. move semantics vs const ref. If I apply the fix-it to use copy/std::move, 
the then immediately get another one to apply const-ref. Which one is right?
4. Move constructor definition to .h (for constructors) is this "a thing"?
5. Not sure what it takes, but a fixit for "warning: {class} has virtual 
functions but non-virtual destructor" should have minimally a fix as 
"~{class}() override = default;"
6. I find it confusing to have the triangle warning: off to the right but the 
lightbulb at the the end of the text. (Also attached) It would be cool if the 
lightbulb could be the triangle (or vise-versa) and clicking on it would fix it.
7. Double-clicking on fix gets me every time. I click, wait, oh, double-click.
8. "error: static_cast from {derivedclass*} to {baseclass*}, which are not 
related by inheritance..." and variations of the above... It seems that 
whatever is claiming this is flat out wrong because deriveddclass is actually 
derived from baseclass.

Re: [Qt-creator] Multiple Android APK support?

[Nikos Chantziaras]

When uploading the x86 build, the site replaces the previous build 
unless you select "Retain" for it. Once you do that, it does seem to 
work and both APKs seem to be active. You get a warning though about 
"Differentiating APK details", but it's not a hard-error.


But it seems the site considers the highest version number as the "real" 
version. Pre-launch data for example isn't available for the ARM build, 
unless you reverse the version numbers, in which case you get data for 
the ARM build, but not the x86 one.


So it seems to work, but seems to be kinda glitchy. I assume the 
"correct" way would be to add architecture information to the manifest 
and gradle files, but Creator doesn't seem to offer a way to generate these.

Re: [Qt-creator] Memory usage of Qt Creator

[Carel Combrink]

Hi,

I work on a quite large application and my clangbackend crashes often due
to running out of memory.
I am using Qt Creator 4.6.0 [Qt 5.10.1 (MSVC 2015, 32 bit)]
Thus if the clangbackend reaches about 1.4GB of RAM it crashes, then starts
growing again, rinse and repeat... Switching to 64 but will not solve the
issue, since I only have about 2 GB RAM free, thus crashing the
clangbackend is better compared to crashing everything. (Sometimes the
compiler crash due to running out of memory).

My current numbers as I am typing this:
Image Name | Memory (Private Working Set )
-|--
clangbackend.exe *32 | 751 976K
qtcreator *32 | 592 004K

Regards,
Carel

[Qt-creator] Memory usage of Qt Creator

[timur . kristof]

Hi,

Just noticed that with the latest version of Qt Creator the memory
usage numbers went up.

Currently I get ~400MiB for qtcreator and ~450MiB for clangbackend.
This seems to slowly go down after I close some source files, though it
takes time (guess it keeps them in cache for a while).

Are these figures normal / expected?

Best regards,
Timur

Another one that some people use for Qt Creator code is here: 
http://code.qt.io/cgit/qt-creator/qt-creator.git/tree/dist/clangformat/.clang-format

(no idea where they differ)

There is one at

I'm working on a project which uses the Qt coding style.
Does you guys have a .clang-format config file for this style which I

Re: [Qt-creator] Multiple Android APK support?

[Ivan Donchevskii]

As far as I know store expects both in the same apk.
So as I understand you suggest having two different versions in store for 
different platforms?
That may work. Thanks for one more workaround :)

Ivan
