Plasma Team meeting, 21-08-2017
Present: mgraesslin, fvogt, notmart, bshah, Sho_, d_ed
mgraesslin:
* I'm working on what I call the "XFree KWin" project
** trying to get KWin/Wayland to work without XWayland
** thus moving lots of code into the x11 standalone platform
** once we get KWin work without XWayland I hope to also be able to handle XWayland crashing
** related to all of that, refactored events.cpp to get more dedicated event handlers
** and started moving the compositors into plugins
* oh and on the general Wayland stuff: ShellClient's caption is now feature complete with X11 Client's caption
fvogt:
* Tried to fix annoying warning on Qt startup about QQC1 style "org.kde.desktop" not being found. First attempt broke weirdly due to bugs in Qt's style selection method, hacked around it with QT_QUICK_CONTROLS_1_STYLE="non/existent/dir/Desktop"
* Noticed with notmart that while qqc2-style was supposed to be released as part of Plasma 5.10, it was not. Nobody noticed apparently
* (Not really plasma) Did an experiment to get QColumnView into the KIO file dialog, QColumnView is extremely buggy and needs a *lot* of work
notmart:
* finalized kirigami layers
* national holiday on 15th
* ported koko to it as a proof of concept
* kirigami icon sizes in desktop style
* wayland: foreign protocol,
** refactoring in a single class server side
** more testing on fail cases, when surfaces or pieces of wrapper get deleted
** https://phabricator.kde.org/D7369
** got completely frustrated by random crashes, weird memory corruptions and useless backtraces
** proposed an api change on wayland-devel list
bshah:
* [Neon] WIP still to add the armhf in mobile CI
** Mostly tooling fixes where things just assumed that there is only one architecture
* [Misc] Got a chance to test touch screen stuff on my new laptop, have some ideas (some inspired from the windows though :p), for example:
** Converge kickoff/kicker to appdash when keyboard is folded away?
** Provide ability to hide mouse? Windows provides this "Tablet mode" toggle which does this
** Some more not-so-concrete ideas, can discuss them post meeting in breakout
** This also means I can test screen rotation stuff from sebas :)
* mostly time was spent doing non plasma/mobile or halium work (neon)
Sho_:
* [Desktop] Fixed 5.10 regressions causing desktop widget position loss at shell restart due to size hints vs. position code ping-pong, ate lots of time last week for ultimately somewhat unsatisfying timer delay solution
** I have a suicidal impulse to rewrite the desktop containment widgets layer now, trying to resist
* [Kicker] Fixed search field losing focus after first typed character when searching while hovering top-level category item
* [Other] Submitted an entry into the KDE community Goals process that impacts Plasma heavily: https://mail.kde.org/pipermail/kde-community/2017q3/003913.html
* [Other] Some QtWS'17 coordination (help leinir with showing off Plasma!): https://mail.kde.org/pipermail/kde-community/2017q3/003916.html
* [Other] Started Qt Quick/Kirigami version of Konversation on the side, http://i.imgur.com/RPFDPoN.png
d_ed:
* I modded the baloo runner to work out of process.
** which is a good test of my DBus runners
* made kwin tell wayland windows which output they're on
** which Qt now also has a patch for
* oh, and I redid the kscreen scaling dialogs to have the per-screen support.
Full log:
[19:01] <Sho_> meeting time! mgraesslin, bshah, d_ed, sebas, notmart, Riddell, kbroulik, fvogt, others: who be here
[19:01] * mgraesslin is here
[19:01] * fvogt is here as well
[19:01] * notmart here
[19:01] * Sho_ has a feeling bshah is also here
[19:01] * bshah is here
[19:02] <Sho_> ah there we go :P
[19:02] <Sho_> seems a bit light today, where are the others? humm
[19:02] <Sho_> anyhow, mgraesslin starts, fvogt next
[19:02] <mgraesslin> hello, first time around in a long time :-)
[19:02] <mgraesslin> I'm working on what I call the "XFree KWin" project
[19:03] <mgraesslin> trying to get KWin/Wayland to work without XWayland
[19:03] <mgraesslin> thus moving lots of code into the x11 standalone platform
[19:03] <Sho_> neat :)
[19:03] <heliocastro> mgraesslin: Just congrats for your wedding ( sorry for interrupt )
[19:03] <bshah> yay lovely
[19:03] <mgraesslin> general idea: code which isn't compiled in, cannot create issues
[19:03] <mgraesslin> heliocastro: thanks
[19:03] <mgraesslin> once we get KWin work without XWayland I hope to also be able to handle XWayland crashing
[19:04] <mgraesslin> related to all of that, refactored events.cpp to get more dedicated event handlers
[19:04] <mgraesslin> and started moving the compositors into plugins
[19:04] <Sho_> seems the event handlers/filter concept is really working out in general
[19:04] <mgraesslin> mostly yes
[19:05] <mgraesslin> a general problem is that we have an ordering in the event handlers currently
[19:05] <mgraesslin> and that ordering is partially important
[19:05] <mgraesslin> so these things need to stay unfortunately
[19:05] --> Delta-One (~zero at 2001:2002:51e2:7ba1:6391:acc7:b55f:c617) has joined this channel.
[19:06] <mgraesslin> oh and on the general Wayland stuff: ShellClient's caption is now feature complete with X11 Client's caption
[19:06] <mgraesslin> next()
[19:06] <bshah> mgraesslin: a question
[19:06] <mgraesslin> yes?
[19:06] <bshah> mgraesslin: are the tasks which needs to be done for XFree Kwin, listed somewhere?
[19:07] <mgraesslin> no
[19:07] <mgraesslin> I don't know the tasks myself
[19:07] <mgraesslin> I mostly read code, find an area and fix it
[19:07] <bshah> okay, fair enough
[19:07] <mgraesslin> code coverage helps
[19:07] <mgraesslin> files which have bad coverage are good candidates ;-)
[19:07] <bshah> hehe
[19:07] <Sho_> i'd say we have enough wayland tasks that /are/ listed though, so while martin does that stuff if others want to do wayland bits it's not hard to find todos ;)
[19:08] <Sho_> fvogt is next btw, after that is notmart
[19:08] <bshah> Sho_: well I am actually quite interested in Xfree kwin thing.. (plasma mobile perspective)
[19:08] <Sho_> bshah: oh right, makes sense
[19:08] <bshah> but yeah, fvogt, go ahead
[19:08] <-- cotko (~ahmed at 89-212-138-82.static.t-2.net) has left this server (Ping timeout: 246 seconds).
[19:08] <fvogt> - Tried to fix annoying warning on Qt startup about QQC1 style "org.kde.desktop" not being found. First attempt broke weirdly due to bugs in Qt's style selection method, hacked around it with QT_QUICK_CONTROLS_1_STYLE="non/existent/dir/Desktop"
[19:08] <fvogt> - Noticed with notmart that while qqc2-style was supposed to be released as part of Plasma 5.10, it was not. Nobody noticed apparently
[19:09] --> cotko (~ahmed at 89-212-138-82.static.t-2.net) has joined this channel.
[19:09] <Sho_> /o\
[19:09] <Sho_> how can we fix the "nobody noticed" problem next time?
[19:09] <fvogt> - (Not really plasma) Did an experiment to get QColumnView into the KIO file dialog, QColumnView is extremely buggy and needs a *lot* of work
[19:09] <Sho_> can't we generate "what needs to be released" from the dep data?
[19:10] <fvogt> It's not a dep of anything
[19:10] <notmart> i tought that whatever was in w0rkspace/ must be in next release
[19:10] <fvogt> Only plasma-workspace references it by setting the QQC2 style to org.kde.desktop
[19:10] <Sho_> i thought maybe the dep data had a "this is plasma" item
[19:10] <-- starbuck-office (~netrunner at p4FD07690.dip0.t-ipconnect.de) has left this server (Quit: Konversation terminated!).
[19:11] <notmart> which i tought was the location in the repo, apparently not
[19:11] <Sho_> but maybe makes sense to discuss this next week with Riddell there?
[19:11] <notmart> sure
[19:11] <Sho_> alright, let's try not to forget :)
[19:11] <Sho_> notmart is next
[19:11] <fvogt> notmart: BTW, I installed it and it works fine here :-)
[19:11] <notmart> yay :)

[19:12] <notmart> * finalized kirigami layers
[19:12] <notmart> * national holiday on 15th
[19:12] <notmart> * ported koko to it as a proof of concept
[19:12] <notmart> * kirigami icon sizes in desktop style

[19:12] <notmart> ** got completely frustrated by random crashes, weird memory corruptions and useless backtraces
[19:12] <notmart> ** proposed an api change on wayland-devel list
[19:13] <notmart> that's pretty much my part
[19:13] <Sho_> what's kigirami layers?
[19:13] <notmart> but a lot of the time was spent into staring at valgrind or gdb to no avail :p
[19:13] * Sho_ appreciates enduring the frustration gauntlet :)
[19:13] <notmart> Sho_: is a stack view that now wrap arounds to the columns view
[19:13] <Sho_> what's it for?
[19:14] <notmart> so if the application needs to have a layer that covers all the columns, temporarly disabling the horizontal navigation it can
[19:14] <Sho_> ah
[19:14] <notmart> mostly for things that are a viewer of something, like koko or peruse
[19:14] <Sho_> cool
[19:14] <notmart> where when you are in the mode of viewing the thing you are completely outside of the navigation mode
[19:15] <Sho_> right
[19:15] <Sho_> "breakout mode" :P
[19:15] <Sho_> alrighty, bshah is up
[19:15] <bshah> okay
[19:15] <bshah> - [Neon] WIP still to add the armhf in mobile CI
[19:15] <bshah> - Mostly tooling fixes where things just assumed that there is only one architecture
[19:15] <bshah> - [Misc] Got a chance to test touch screen stuff on my new laptop, have some ideas (some inspired from the windows though :p), for example:

[19:16] <bshah> mostly time was spent doing non plasma/mobile or halium work (neon)
[19:16] <bshah> questions? or next
[19:17] <Sho_> bshah: i also had a long-standing goal to add soem system toggles to dashboard (wifi, bluetooth, etc.) in hybrid/touch mode
[19:17] <Sho_> somewhat thwarted by the difficulty of actually making my touchscreen work on my laptop
[19:18] <bshah> for me it just worked :p
[19:18] <Sho_> alright, i'll post my notes:
[19:18] <Sho_> * [Desktop] Fixed 5.10 regressions causing desktop widget position loss at shell restart due to size hints vs. position code ping-pong, ate lots of time last week for ultimately somewhat unsatisfying timer delay solution
[19:18] <Sho_> ** I have a suicidal impulse to rewrite the desktop containment widgets layer now, trying to resist
[19:18] <Sho_> * [Kicker] Fixed search field losing focus after first typed character when searching while hovering top-level category item
[19:18] <Sho_> * [Other] Submitted an entry into the KDE community Goals process that impacts Plasma heavily: https://mail.kde.org/pipermail/kde-community/2017q3/003913.html
[19:18] <Sho_> * [Other] Some QtWS'17 coordination (help leinir with showing off Plasma!): https://mail.kde.org/pipermail/kde-community/2017q3/003916.html
[19:18] <Sho_> * [Other] Started Qt Quick/Kirigami version of Konversation on the side, http://i.imgur.com/RPFDPoN.png
[19:18] <mgraesslin> bshah: anything new on the failing kwin on the one device?
[19:20] <d_ed> notmart: I didn't have a chance to look at your xdg-foreign issue
[19:20] <d_ed> I hope to do so this afternoon
[19:20] <notmart> no problem :)
[19:20] <Sho_> d_ed, wanna take a turn too?
[19:20] <d_ed> sure
[19:20] <Sho_> go go go
[19:20] <d_ed> I modded the baloo runner to work out of process.
[19:20] <d_ed> which is a good test of my DBus runners
[19:21] <mgraesslin> an awesome idea btw.
[19:21] <d_ed> Sho_: if you can test the kicker stuff is the same, that'd be really good
[19:21] <notmart> yay for baloo runner out of preocess \o/
[19:21] <Sho_> d_ed: is it merged or testing the phabs?
[19:21] <d_ed> Sho_: will merge in a sec
[19:21] <Sho_> k
[19:21] <d_ed> made kwin tell wayland windows which output they're on
[19:22] <d_ed> which Qt now also has a patch for
[19:22] <d_ed> (what's nice is the Qt guy added me as a reviewer for his patch, and also subscribed to the kwin patch..so hopefully that's a sign of some better collab
[19:22] <d_ed> (
[19:22] <mgraesslin> is Qt also able to adjust the scale automagically?
[19:22] <d_ed> it doesn't yet
[19:22] <d_ed> nor does it adjust it when the output itself changes
[19:23] <d_ed> but that's obviously the next step
[19:23] <mgraesslin> what about GTK? Does it work for them?
[19:24] <d_ed> I tried doing that in Qt, it worked, but the frame looks weird for a while even though I retriggerered an expose event
[19:24] <d_ed> so I'll wait for the Qt guy to do it :D
[19:24] <bshah> mgraesslin: they managed to run kwin in framebuffer mode on qemu with their setup (consolekit + musl libc on alpine) https://www.reddit.com/r/postmarketOS/comments/6uoxlr/postmarketosdemos_running_on_kwin but AFAIK not tested on real device yet
[19:24] <d_ed> mgraesslin: I don't actually know. I'll test and let you know
[19:25] <mgraesslin> d_ed: from my understandig GTK should just work
[19:25] <mgraesslin> bshah: though honestly fbdev is pretty much pointless up to the point that I started considering to delete it
[19:26] <bshah> mgraesslin: kinda right... yeah
[19:26] <fvogt> Some HW doesn't have proper DRM though :-/
[19:26] <mgraesslin> that's the point why it's still there
[19:27] <d_ed> oh, and I redid the kscreen scaling dialogs to have the per-screen support.
[19:27] <Sho_> nifty
[19:27] <Sho_> alrighty
[19:27] <Sho_> i'll close the meeting now and get to notes, feel free to discuss more :)
[19:28] <mgraesslin> my normal "KDE times" got a problem currently: https://www.bo.de/sites/default/files/styles/artikeldetail/public/field/image/img_6254.jpg?itok=XnJAiX2y
[19:28] <bshah> Sho_: thanks for hosting
[19:28] <mgraesslin> due to that I have to commute by car
[19:28] <notmart> what happened?
[19:28] <mgraesslin> which of course makes it impossible to hack on KDE
[19:28] * Sho_ commutes by bike lately
[19:28] <d_ed> that tape will definitely stop a train
[19:29] <mgraesslin> notmart: German railway tried to build a tunnel on sand five meters below that railway track
[19:29] <bshah> d_ed: 100% sure? :P
[19:29] <mgraesslin> and well it collapsed
[19:29] <notmart> lol
