Greetings once more. Recently I've been doing some testing of the new cmake-based configure on Linux. (It would be awesome if someone can do the same for other platforms.)
Perhaps naively, I started out by running configure with each command-line flag listed by the old version of "configure -help", expecting the new configure to be a drop-in replacement. Naturally for something so new, I found a few regressions (many thanks to the build system guys for responding to these issues so quickly) and a couple of features of the old configure that were already broken (perhaps evidence that those features are unused and could be retired). A couple of the bugs I filed were about configure features that went away after being supported for more than ten years. Another relates to PostgreSQL support on OpenSuSE, which worked fine for Qt4 and Qt5 but is broken for Qt6, apparently due to a long-standing bug in cmake (or a bug in OpenSuSE depending on your point of view). For the C++ bits of Qt, we have long-established and well-understood policies for source- and binary-compatibility and for deprecating features in a way that telegraphs our intentions well in advance of functionality disappearing. I can't find any equivalent policies for the other parts of Qt. So, what I want to know is: 1. Are our customers entitled to expect that features of non-C++ parts of Qt won't disappear without first being flagged as deprecated, and documented as deprecated, for a reasonable period, in line with the policy for the Qt libraries? 2. If long-standing Qt functionality is broken by external vendors who can't agree on who should fix it, how hard am I entitled to push for our developers to try to work around the problem to keep the functionality working for our customers, versus giving up and just documenting the breakage in the Qt5 to Qt6 porting docs?
