00:03 erlehmann sfan5 what do you think of https://danluu.com/everything-is-broken/ ? (the part after “WAT”)
00:12 rubenwardy https://github.com/minetest/minetest/releases/tag/5.4.2-android
00:12 rubenwardy I've set roll out to 6%. If the crash rate is stable, will increase in a few days
00:13 tekakutli joined #minetest-dev
00:22 erlehmann rubenwardy could you explain what is a good crash rate for minetest and where to see it as a third party?
00:23 rubenwardy it's private
00:23 rubenwardy I don't think there's anyway to make the Play Store dashboard public
00:23 rubenwardy and "good" in this context is "not significantly more than the last release"
00:23 rubenwardy Minetest's Android crash rate is terrible
00:24 rubenwardy such that you have red text and  /!\  on the dashboard
00:24 rubenwardy I'm trying to attach native debug symbols so I can get proper tracebacks for NDK/c++ crashes, but Android Studio doesn't seem to want to produce it
00:25 erlehmann rubenwardy so how high is it?
00:26 rubenwardy 92.4% daily sessions without crashes
00:26 erlehmann i have never done mobile dev, only advised them on security (spoiler: they only ever take advice on TLS usage and OAuth2, they never take advice on checking inputs)
00:26 rubenwardy 81.6% daily sessions without freezes
00:27 rubenwardy and: https://i.rubenwardy.com/oLi4u.png
00:27 erlehmann oh that sounds horrible, but how long is such a session? (median)
00:27 rubenwardy no idea
00:27 rubenwardy I think a session is one opening of the app
00:27 rubenwardy but I'm not sure
00:28 rubenwardy there were 19k sessions between 23 Sep and 23 Opt
00:28 calcul0n_ joined #minetest-dev
00:28 erlehmann yeah i mean i can probably get minetest to crash if i play for a few hours
00:28 rubenwardy it is terrible
00:28 erlehmann it happens
00:28 erlehmann how do you get stuck in a wakelock though?
00:30 rubenwardy don't know
00:30 rubenwardy https://i.rubenwardy.com/ytcO5.png
00:31 rubenwardy you get crash reports like this
00:31 rubenwardy the NDK crashes have no tracebacks
00:31 rubenwardy well they do but they're fairly meaningless
00:33 erlehmann rubenwardy this looks horrible for debugging :(
00:34 rubenwardy it would be okay if it wasn't so slow, and if they actually had tracebacks
00:34 rubenwardy the latter is a matter of us working out how to export them
00:34 rubenwardy s/them/debug symbols/

00:35 erlehmann rubenwardy if you want more crashes, try to compile it with the minimal ubsan runtime (the one that has little overhead)

10:34 MTDiscord <luatic> IrrlichtMt bug report on ContentDB: https://content.minetest.net/threads/1395/
11:01 sfan5 rubenwardy: good job
11:01 sfan5 for debug symbols uploading the .so files from the obj/local/$abi/ folder should work
11:02 sfan5 (those should not be already stripped)
11:25 sfan5 @luatic could be in IrrlichtMt of course but I don't see a direct connection
11:25 sfan5 should be filed on minetest/minetest first
11:27 proller joined #minetest-dev
12:16 MTDiscord <josiah_wi> Interesting update, some assertions checking matrix rotation in Irrlicht fail on OpenBSD. Maybe not too important, but kind of a fun progress update. I intend to open an issue once I have more debugging information.
12:17 MTDiscord <josiah_wi> I'll also PR the fix for this if I'm able to fix it. I don't know yet how difficult it will be to figure out.
