09:06 < ghost43> re the macOS release builds; is either the .dmg or the .app inside "notarized" by Apple? or are they only codesigned?
09:09 < ghost43> oh I see there is an open issue about it. https://github.com/bitcoin/bitcoin/issues/15774

15:22 < achow101> luke-jr: does the build fail on just running out of disk space?
15:25 < achow101> if anyone who uses lxc for gitian wants to help me test #22439, that'd be great. I'm able to get it to work by adding "lxc.apparmor.allow_nesting=1" to etc/lxc.3.config.in, but it just hangs at the completion of the script instead of exiting like it's supposed to

18:44 < luke-jr> achow101: failed with: comm: cache_store_files: No such file or directory
18:44 < achow101> luke-jr: pull the latest commit, that was an old version that doesn't work
18:45 < achow101> but if you made it that far, then the build completed and it's just the caching that failed
18:45 < luke-jr> >_<
18:45 < luke-jr> wonder if I can avoid redownloading everything yet again
18:45 < achow101> if the vm is still running, you could ssh into it and pull the cache manually
18:47 < luke-jr> is that the usual gitian cache sync, or something more complex?
18:48 < achow101> there's a guix specific cache file that is created and dumped into the gitian common cache directory
18:48 < luke-jr> don't see any of the guix stuff in the normal cache :/
18:48 < luke-jr> not that I see
18:48 < achow101> it should be in common/guix/guix_store.nar
18:48 < luke-jr> common/guix/ is empty :/
18:48 < achow101> err, rather, not yet because it failed before the cache was made
18:49 < achow101> do these steps: https://github.com/bitcoin/bitcoin/pull/22439/files#diff-f2a08e4146be5a2e10a2555330270f36448892b6e02e745cb49e4e7f7800e3f5R77 and you will make the cache files
18:50 < achow101> ${STORE_FILE} should be /home/ubuntu/common/cache/guix/guix_store.nar and ${KEYFILE} should be /home/ubuntu/cache/guix/signing-key.pub
18:51 < achow101> you might need to start the guix daemon: https://github.com/bitcoin/bitcoin/pull/22439/files#diff-f2a08e4146be5a2e10a2555330270f36448892b6e02e745cb49e4e7f7800e3f5R46
18:51 < luke-jr> KEYFILE doesn't exist?
18:52 < luke-jr> cp: cannot create regular file '/home/ubuntu/cache/guix/signing-key.pub': No such file or directory
18:53 < achow101> oops, mistyed some paths
18:53 < achow101> it's the in the same common/guix directory
18:54 < luke-jr> 56G used fwiw
18:54 < achow101> fun
18:54 < luke-jr> cache/common is 7.3 GB
18:54 < luke-jr> (so far)
18:54 < luke-jr> 8.4 GB now
18:55 < achow101> mine is 9.1 GB
18:55 < achow101> of which 8.6 is the guix store
18:55 < luke-jr> O.o
18:56 < luke-jr> mine was 2.9 GB before this
18:56 < achow101> so the two guix files should be cache/common/guix/guix_store.nar, and cache/common/guix/signing-key.pub
18:57 < achow101> guix_store.nar is basically a tarball containing all of the stuff that guix downloads/builds to setup the build environment. so it's a little big
18:57 < luke-jr> 5.3 GB .nar file
18:57 < luke-jr> it doesn't fit on my host vfat filesystem! /s
18:58 < achow101> but you'll really want that cache so you don't spend ages rebuilding and redownloading the same guix packages
18:58 < luke-jr> achow101: is .nar compressed before or after combining?
18:58 < luke-jr> (should I include it in my backups, or will it change every build?)
18:59 < achow101> I'm not sure
19:00 < achow101> actually, part of it will change every time, as will signing-key.pub
19:00 < achow101> it generates a new signing key and signs the .nar when making the cache, so that signature and the key end up changing after each build
19:00 < luke-jr> right, but is the whole 5 GB going to change, or just a header or something
19:01 < achow101> "Second, the order in which directory entries are stored always follows the order of file names according to the C locale collation order. This makes archive production fully deterministic. " I'm going to go with no
19:01 < achow101> so long as the packages don't change, which they won't unless we update the package manifest
19:01 < luke-jr> every new release probably will add more pkgs tho
19:02 < luke-jr> maybe teh common cache should just be things like the old libc?
19:03 < luke-jr> [1626228086.784]: [ INFO ] Downloading Guix release archive
19:03 < achow101> I think dongcarl has/is going to open an issue upstream to allow `guix archive` to take a manifest file so that we just cache the packages we need instead of the entire store
19:03 < luke-jr>  :/
19:03 < sipa> i believe the nar file is uncompressed
19:03 < achow101> unfortunately I haven't figured out how to not download the guix binary every time
19:04 < luke-jr>    150K ………. ………. ………. ………. ……….  0% 2.22K 15h31m
19:05 < achow101> wait, I'm dumb, it should be really easy to cache that
19:05 < luke-jr> no clue why it's only 2k/s
19:06  * luke-jr restarts gbuild
19:07  * luke-jr ponders making gitian use virtfs instead of copying the entire cache every time
19:08 < luke-jr>  16350K ………. ………. ………. ………. ………. 18% 4.77M 40s
19:08 < luke-jr> somewhat better
19:11 < luke-jr> Updating channel 'guix' from Git repository at 'https://github.com/dongcarl/guix.git'…
19:12 < luke-jr> it still needs dongcarl's personal guix fork?
