qt: Log Qt related info #17826

hebasto · 2019-12-29T16:38:01Z

This PR adds some info to debug.log I found useful for testing (e.g., on Wayland) and debugging issues like #17153:

-host is to confusing in my opinion. I think something like -debuginfo or -sysinfo would be better

Concept ACK, but yes, -host is confusing. I would expect it to do something with P2P.

-host is to confusing in my opinion. I think something like -debuginfo or -sysinfo would be better

yes, or -guiinfo or -qtinfo, to make it clear this is GUI specific

hebasto · 2020-01-03T11:53:30Z

@emilengler @laanwj
Thank you for your reviews. Your comments have been addressed.
-qtinfo is chosen as the shortest string.

The OP and the title have been updated.
Added info about Qt version and link type.

sipa · 2020-01-03T12:33:34Z

Wouldn't it be better to add this information to -version? That's where I would expect it.

EDIT: hmm, maybe not as it's not just Qt version information but also X stuff.

hebasto · 2020-01-03T12:38:17Z

@sipa

Wouldn't it be better to add this information to -version? That's where I would expect it.

-version also contains a huge piece of license info.
-qtinfo is intended to supply some environment info, that seems a bit unappropriated for -version output, no?

cvengler · 2020-01-03T19:02:59Z

@sipa

Wouldn't it be better to add this information to -version? That's where I would expect it.

I think help2man would have issues with it and it would be weird on the GNU userland if it would contain information that is not the version and license stuff.

hebasto · 2020-01-03T20:41:59Z

I think help2man would have issues with it...

help2man relies on gen-manpages.sh wrapper which in turn relies on bitcoind -version.

sipa · 2020-01-04T08:38:54Z

@hebasto You're right, the environment information does not belong in -version.

hebasto · 2020-01-04T09:51:40Z

@sipa

@hebasto You're right, the environment information does not belong in -version.

Does it mean "Concept ACK"? 😄

Concept ACK

laanwj · 2020-01-04T11:35:29Z

Wouldn't it be better to add this information to -version? That's where I would expect it.

I personally prefer -version to be a short message that just states the version. And some license info. I think it's currently fine. I wouldn't expect all kind of window system information there.

Thinking of it, this is for troubleshooting right? Let's just always log this in a message to the debug log instead of adding another step?

Now it detects all the screens associated with the windowing system the application is connected to.
Please test.

Are these concerns relevant https://stackoverflow.com/questions/35811053/using-c11-range-based-for-loop-correctly-in-qt ?

It's fine here, these are pointers.
