ahasenackstarting my +1 maintenance shift week11:59
ahasenackhit me11:59
ginggsahasenack: ignore all r-bioc-*, they're in transition in Debian12:13
ahasenackphew12:13
ahasenack$ ./find-proposed-cluster -s mantic12:13
ahasenackr-bioc-biocgenerics 16012:13
ahasenack(...)12:13
ginggsi retried all build failures in mantic-proposed12:14
ahasenacklooking at haskell then12:17
ahasenackhttps://launchpad.net/ubuntu/+source/haskell-gi-gio/2.0.30-1build3 might be what will unblock it, armhf build ongoing13:38
ahasenack5h building, and counting, ouch13:38
ahasenackhm, previous build took just 1h18min13:43
ahasenackwonder if it's stuck13:43
ahasenackLocutusOfBorg: I wonder if https://launchpad.net/ubuntu/+source/haskell-gi-gio/2.0.30-1build3/+build/26482467 should be cancelled, and retried13:48
ahasenackit feels stuck13:48
* ahasenack hovers over the cancel button13:51
ahasenackrestarted the build14:04
* ginggs looks at libmedia-convert-perl vs ffmpeg, which might unblock bctoolbox14:06
ahasenackthis will take a bit, so next. rust-phf14:17
LocutusOfBorgahasenack, thanks, I'm monitoring them, haskell and ocaml should go in 2-3 days14:28
LocutusOfBorg(ocaml today I guess)14:28
LocutusOfBorgffmpeg/vim are the worst painful ones14:28
LocutusOfBorgthey block *lots*14:28
ahasenackthat armhf builder is slow14:28
ahasenackI'm doing a build in another arm machine, started both at the same time, and mine is at [240 of 300]14:28
ahasenackwhile the lp one is at [15 of 300]14:29
ahasenackbut at least it's not stuck14:29
LocutusOfBorgfor some reason armhf for ghc regressed a lot14:29
LocutusOfBorgand we never found why14:29
ahasenackyou mean in terms of speed?14:29
LocutusOfBorgyes, ghc became SO SLOW in building14:29
ahasenack:/14:29
LocutusOfBorgeven ghc in building itself14:29
LocutusOfBorgand I remember vorlon debugging it some bits14:29
ahasenackone thing I noticed is that it's not using parallel jobs14:30
LocutusOfBorgI had to switch to unregisterised build for armhf, that worked better, and then use that ghc to build the registerised one14:30
ahasenackeven though I passed --jobs=8014:30
ahasenackso 79 cores are idling now in this machine14:30
LocutusOfBorgahasenack, I don't remember, let me chec14:43
LocutusOfBorg*check14:43
ahasenackhm, anyone familiar with rust-pallete here? It has a versioned build-dep: https://salsa.debian.org/debian/rust-palette/-/blob/debian/latest/debian/control#L1514:44
ahasenackon librust-phf-0.10, and we now have 0.1114:44
ahasenacksounds like a simple bump, and it builds fine with the new one14:44
* ahasenack wonders how that migrated in debian14:44
ahasenackwell, should be simple to prove now that -palette is an ftbfs in debian14:45
LocutusOfBorg    Fix "support for DEB_BUILD_OPTIONS=parallel=n broken" dh_haskell_build: Remove support for parallel=n. (Closes: #536589)14:46
ahasenackit's even uninstallable in debian now, and salsa doesn't take merges for it14:46
LocutusOfBorgwow, 200914:46
ahasenackLocutusOfBorg: maybe it's fixed now? :)14:47
ginggslibmedia-convert-perl passed on ppc64el and s390x, holding thumbs for arm6414:47
ginggs(seems the new ffmpeg pushed into OOM, I suspect that because it passed on armhf and amd64)14:48
LocutusOfBorgahasenack, https://github.com/ghc-proposals/ghc-proposals/pull/54014:50
-ubottu:#ubuntu-devel- Pull 540 in ghc-proposals/ghc-proposals "jsem: parallelism semaphores" [Merged]14:50
LocutusOfBorgmaybe cabal will support them *soon*14:50
LocutusOfBorghttps://github.com/haskell/cabal/issues/97614:51

LocutusOfBorghttps://well-typed.com/blog/2023/08/reducing-haskell-parallel-build-times/14:51
LocutusOfBorgsomething from this month, after 14 years it got implemented :D14:51
LocutusOfBorgso, somebody has to put a note on calendar to enable again parallel building?14:51
ahasenackthat pr was merged last year,14:53
LocutusOfBorgyeah14:54
ahasenack976 still open14:54

ahasenackarmhf userspace, I wonder if that was it (32bit: does armhf have something similar to PAE?)15:28
ahasenackbut the kernel is arm64 (it's the trick of running armhf lxd on arm64 host)15:28
ahasenackLocutusOfBorg: that was my "local" build of haskell-gi-gio in armhf15:29
* ahasenack -> lunch15:30
LocutusOfBorgmeh, the kernel arm64 and chroot armhf is what was probably the culprit15:30
ahasenackok, rust-palette 0.7.2+dfsg-3 will help/fix the rust-phf migration16:24
ahasenackit's building in debian16:24
ginggsooh, looks like bctoolbox and ffmpeg and friends are migrating \o/17:06
ginggswith that, I will EOD!17:07

tewardddstreet: mapreri: I want to reject #2030675 from backports.  No developer backing the request, and FTBFS as is.  "It's possible the source package is too new, and would need modification" - not our job, and with no developer backing the request, I think this is a prime case for a rejection.  Thoughts before I pull the "reject" button out?21:22
