RPJaMa: I feel bad for having projects I don't get to, rusty or otherwise!08:06
LetoThe2ndRP: isn't that just generic IT people?08:12
RPLetoThe2nd: probably but I have been making an effort to try and sort some of them as it was getting bad08:15
JaMaRP: I know, I have the same "disease"08:29
JaMaI partially envy people who can completely forget about the projects they were excited about just 2 weeks ago08:30
*** florian_kc <florian_kc!~florian@port-217-146-132-69.static.as20676.net> has joined #oe08:34
LetoThe2ndIn my case, usually a "side project" means "3-5 open browser tabs". They accumulate, and whenever I can't read the titles anymore, I need to "forget" about a few.08:42
JaMasince chrome introduced tab groups, I have grown my side tabs 10 times (with 1 letter group names) - before I dump them as bookmarks "for future"08:45
JaMaand using 4K 48" oled as a monitor helps with vertical space08:47
LetoThe2ndTechnically correct, but I switch around quite a bit, so whatever is uncomfortable on a 14" laptop is not suitable for me.08:48
* JaMa understands, but I'm uncomfortable with any laptop08:49
JaMaso when I have to travel I take external keyboard, mouse and a TV :)08:49
LetoThe2ndhehe08:50
LetoThe2ndit depends (TM)08:50
JaMaI might be clumsy, but I hate when my thumb touches the touchpad while typing on keyboard, so I either have to disable touchpad (and use mouse) or use external keyboard+mouse (which I prefer, because of keylayout anyway)08:51
LetoThe2ndyeah same here, I usually have an Atreus keyboard. But still I often do stuff in cafes/restaurants/trains/on sofas quite a bit, so it has to at least "work" well enough with only the laptop.08:53

* RP has hundreds of browser tabs, another bad habit :/09:49
paulgslowly take out your RAM one stick at a time.  Habit solved.09:51
RPpaulg: I ended up buying a laptop with crazy memory :)10:03
paulg<oldguy> It makes me sad that now an old turd with 4GB can barely run a web browser. </oldguy>10:10
paulgin some long distant pre-git past, I'd made some kind of change to gnu diff to speed up "diff -u kernel-A kernel-B"10:15
paulgLinus was boasting on how he had 1GB RAM and so both kernel trees lived in RAM and hence he didn't suffer the I/O storm that mere mortals did...10:16
paulgA whole 1GB.10:16
paulgPublic e-mail, but a lot of that 1990s stuff has "evaporated".  In theory I still have it in a backup somewhere.10:18
RPpaulg: it would have been very easy to lose matchbox and a load of other 2000s stuff too. It makes me sad things are relatively inefficient with memory but I ended up deciding usability of my day to day work was more helpful that the cost of some RAM :/10:23
paulgyeah, I know fighting against bloat is largely hopeless.10:29
paulgBut I'm still not happy about how rust/llvm/clang native in our builds now causes my older builders to OOM.10:30

marexRP: sakoman: hi, this cpio fix https://lists.gnu.org/archive/html/bug-cpio/2017-07/msg00004.html has been shipping as part of meta-swupdate for like 5 years now, I tried pinging the CPIO upstream about it for a while and it seems the CPIO upstream is effectively dead ... would you be opposed to taking that fix into oe core and backport it to kirkstone/dunfell so everyone can benefit from it ?20:05
marexI am starting to run out of options what to do about that change, sigh20:06

JPEWmarex: Any ideas on how to handle files larger than 4GB?21:16
sakomanmarex: you should submit it for the master branch, and if accepted I can backport21:16
marexsakoman: I mean, sure ... I would ideally get it into cpio proper, but that upstream seems to be dead21:18
marexsakoman: which, I said above, so I guess if you are OK with this kind of change and backporting it, all righty, I will opt for that21:18
sakomanmarex: right, I meant oe-core master branch!21:18
marexJPEW: I am inclined to say, dont use CPIO ;/21:18
marexsakoman: yes, I know21:19
marexJPEW: but then, if your update bundle is over 4 GiB in size ... what are you doing there ?!21:20
*** Xagen <Xagen!~Xagen@99-135-179-142.lightspeed.austtx.sbcglobal.net> has joined #oe21:20
JPEWmarex: You'd be suprised21:20
JPEWmarex: Does swupdate support anything other than cpio?21:21
marexJPEW: try me21:21
JPEWmarex: Well, maybe not suprised per-se, but we will likely encounter the 4GB at some point21:21
JPEW4GB limit21:21
JPEWDebug builds in particular are quite large21:22
JPEWdebug symbols that is21:22
marexJPEW: looking into swupdate, no, I dont think it does support anything but CPIO21:22
marexJPEW: but then, I am also not overly involved with that part21:22
marexJPEW: re debug builds, yeah, good point ... but then, those are likely not shipping as update bundle, and if they are, can you debug with debugfs+gdbserver ?21:23
JPEWmarex: Not yet21:23
JPEWSorry, yes we can do that21:23
marexJPEW: I can also imagine someone can try and include massive container as part of the swu bundle in some streak of evil21:23
JPEWI thought you meant debuginfod21:23
JPEWThe general problem we have with debug symbols is almost entirely a distribution probelm21:24
JPEWe.g. how do we find the symbols that correspond to some image21:24
marexsec, I need to read TFM on debuginfod21:25
marexJPEW: my solution to that is to always store both the image tarball and debugfs tarball, ship the image, and if debugging extract both the image+debugfs into the same dir and point gdb-multiarch into it21:25
marexwith gdbserver running on target21:25
JPEWmarex: Ya, for our public releases that's fine because those are a single point in time that gets archived in the salt mines (with debug symbols). It's the 100's - 100021:26
JPEW's of other builds in the mean time :)21:26
JPEWDaily builds and such21:26
marexJPEW: hum, but those arent shipped via swupdate, so you probably dont have that problem ?21:28
marexJPEW: keep in mind, I am not too deep in swupdate21:29
RPmarex: I guess that should be ok....21:43
marexsakoman: patch is out21:43
marexRP: I am concerned, very much so, since it is patching such a core part of OE which has been basically unchanged for...forever21:43
marexRP: on the other hand, the change has been tested in meta-swupdate, so it should be OKish21:44
RPmarex: as long as cpio doesn't have any interesting ideas about what negative size means...21:44
marexRP: I think by now, CPIO has no ideas anymore ... it is just ... stale21:44
marexCVEs go unfixed, releases do not appear since 2019 ... sigh21:45
RPmarex: it is old school technology21:45
RPmarex: finding people to maintain things is hard :(21:45
marexRP: and that, is only part of the problem ... finding GOOD maintainers is like trying to find unicorns21:46
marexsigh21:47
