I wished I had seen the level of energy y’all are putting right now
into this email thread over the last two years when we discussed
where to go with Qt 6, and when the work actually happened.
IIRC, I complained plenty about QList at the time. I wouldn't be
surprised if I complained about QHash also.
One of the reasons I don't try to contribute more than I do is because,
when I *have* contributed patches, it hasn't accomplished anything.
So far, all I've seen is "C++ also deprecates stuff". You haven't
shown that the deprecations are actually *harmful* to the C++
community. >
Personally, I’m siding with those folks in the committee that
believe that not changing things (ref ABI discussion) is more harmful
than if we’d be able to fix now and again what is objectively
broken.
Likewise.
I've even said before that it might be beneficial if C++ could more
aggressively deprecate bad stuff, even mentioning Qt as an example to
follow.
Not all deprecations are bad. However, I still maintain that *some* of
the Qt 6 changes are problematic. Also, TBH, I think the real issue is
less that Qt 6 made changes, and more that Qt 5 support got pulled well
before Qt 6 is viable for most folks. That didn't happen with Qt 4 → 5.
I also don't recall Qt 4.8 suddenly deprecating a bunch of stuff that
was immediately removed in Qt 5.0, although I may be wrong about that.
I personally wonder why people that never want to change what they
built last year want to develop software development. Isn’t that
what makes building stuff out of bits and ideas so much more
interesting than building stuff out of sticks and stones?
Is this really so surprising? People want to spend their time making
*their* software better, not chasing an ever-shifting foundation on
which their software is *built*.
Time spent adapting to library changes, especially changes seen as
unnecessary or actively harmful, is time *not* spent developing new and
exciting features, or even squashing existing bugs.
