At least I completely fail to see the advantage of c++ style comments for a machine (rather the opposite, since "dumb" appending to lines can now produce undesired results) Either way, Qt5 supports down to MSVC 2010, Qt4 down to MSVC 2008, so either we - raise the bar in kdelibs/KF5 to require a C99 compliant compiler (as a build dep requires it, "we just need //" isn't true - the requirements are controlled outside - ship only pre-produced and hand-fixed code from flex/yacc - pipe flex/yacc results through c++ rather than the C compiler Cheers, Thomas [1] https://gcc.gnu.org/c99status.html

Again: that's processing. The required file was the png (since svg icons were initially not even supported and even now the Qt svg renderer is completely not up to inkscape features extending vanilla svg) If you used gimp, you should put your multilayer .xcf **mt** - it's not simply "multilayer", that's just an intermediate result. The (hypothetical) icon was forged using several destructive processes to get the pixels colorful in the desired way - which are not documented anywhere. It could even haven been done in the very same layer or layer merging was one of the required process steps. A rastered image really completely rests in itself - no matter what tools were used to forge it. A vector editor is just a process detail; the same result could have been achieved in MS paint (with a lot of time ;-) Cheers, Thomas

I cannot see how this would not hurt development. IMO, we can only enforce DMARC once all of our stakeholders support it or for those that do. We're not living in an isolated environment. We can be very strict and religious about standards and enforcing them, but in the end it's going to hurt us, and I don't think that's worth it at all. We'd simply be wasting energy we're putting into KDE, and that's not reasonable dealing with our resources. I think the lack of objections to this plan stems from almost nobody understanding what these plans actually mean for our development processes. The discussion happening around it is therefore not representative, and I think many who would have objected, haven't, for that reason. I can't say that I fully understand it myself. Please reconsider. Cheers, -- sebas http://www.kde.org | http://vizZzion.org

Could this be rolled out in two phases: one where a big fat warning is added in some way, so that we can inform our mailing list masters about the breakage and then a slow enforcement? Kicking out kde.org from important stakeholders doesn't look right to me. And it's not like we would notice. It might take quite some time till we notice no longer incoming mails in mailing list folders. And not everybody read this thread and understood the implications. I do not know how to verify that a mailing list sends correctly and there are important mailing lists I'm subscribed to with low traffic. So: can we do something to notify non compliant mailing lists? And what if they don't act on it? If for example freedesktop.org is slow on it the solution cannot be to effectively kick out kde from freedesktop.org. I'm not going to subscribe there with my private mail address, because it's important to be there with an @kde.org address.

Otoh, developers will prefer to have flex/yacc in the CI and will require a cmake rule to include *.l & *.y in the source list (so it's regenerated on local changes) but otherwise there's (afaik) no strong reason to not simply ship the pre-translated sources (along the lex sources which are usually not invoked on build) The situation is (afaik) slightly different w/ *.moc since you might run into "the moc that generated this header is too old" issues (latter happens, so we can/should not ship pre-built mocs; but I'm not sure whether such problems can show up with lex as well) Cheers, Thomas, Baseball cap - I've not hats.

We have to have preferred form of modification and the ability to rebuild from that source. It's not 100% required that we rebuild, but how do you know you can, unless you do. I don't mind the additional dependency at all. My preference would be that on Linux, at least, if flex/yacc are detected, the rebuilding is automatic. Scott K

The alternative is doing what Gnome did: declare the KDE Frameworks Linux-only. That would be a clear, honest step to take, and I wouldn't actually oppose it.

Back on topic: do you actually have trouble with invoking flex/yacc* to generate code or do you have a problem with the generated (C99) code (what seems to be a pretty new problem - and is on Linux/any distro because KF5 does --std=c90)?

IIRC the problem here is(was) the version of flex/bison used. There was only a very outdated version of flex/bison available for a long time, and this one produced different results from a more modern version. When I looked last, there was a newer build available for both, which was recent enough and which also produced valid results (in at least some cases). I would recommend thus to test those two first, to see if there is a problem at that point at all (and if needed, then it is possible to decide that on a case by case basis - there shouldn't be to many flex/bison uses in total KDE code). About C99: I am not sure which compiler is currently required with MSVC, but if it is 2013 or below, then only some C99 features are supported. I tried to create a C99-to-C90 compiler with the help of clang, but this failed pretty early. So my advice would be to not make C90 default, but to allow some C99 features, but with improved CI instead. regards, Patrick

MSVC 2013 has good support for C99. MSVC 2012 does not. I should point all that MSVC has supported // comments in C sources since before it was known as Visual. But that's not the problem. The problem is the C99 Library, which MSVC did not support until 2013 and it only did so because C++11 imported it by reference. Microsoft does not care for C. They didn't implement C99 because they didn't want to, not because their compiler team was unable to. So my recommendation: write C++ code. -- Thiago Macieira - thiago (AT) macieira.info - thiago (AT) kde.org Software Architect - Intel Open Source Technology Center PGP/GPG: 0x6EF45358; fingerprint: E067 918B B660 DBD1 105C 966C 33F5 F005 6EF4 5358

You can examine the "Authentication-Results" header from any mail that passes through kde.org mail infrastructure to determine if it is valid. These headers should be added by any system which is performing DKIM validation (even if it takes no action based on it) - Google at least also adds these headers. > > Kicking out kde.org from important stakeholders doesn't look right to me.

I would suggest mailing the list administrator or server administrator's of the mailing lists in question. Nobody else really has the power to fix it. The actual server administrators aren't required to take any action as long as you have the assistance of someone who can administrate the mailing list, at least with Mailman.
