 John Ericson | at least no cat and mouse with Apple changing stuff on us | 23:32:00 |
| John Ericson | emilytrau: I am waiting for the build to complete (mes...) but I think I got the parallelism PR working now | 23:33:34 |
| John Ericson | It also separates compilers themselves and libs, which is kind of my hobbyhorse :) | 23:33:53 |
| John Ericson | err not mes, mes is fast, tcc built with mes | 23:34:33 |
| John Ericson | that is slow | 23:34:35 |
| John Ericson | I do want to get cross compilation going at some point (hex0 on one platform, hex1 on another, sure, no problem) and the compiler libs split will help with that | 23:34:53 |
| John Ericson | CA derivations will allow for a sort of dynamic programming like thing where whenever two paths converge, on memoizes | 23:35:54 |
| John Ericson | so instead of num_plats^bootstrapp_steps combinations, there are just num_plats * bootstrapp_steps | 23:36:18 |
| John Ericson | (assuming every step can cross compiler) | 23:36:27 |
| John Ericson | * (assuming every step can cross compile) | 23:36:29 |
| John Ericson | OK build finished, https://github.com/NixOS/nixpkgs/pull/231894 undrafted | 23:42:44 |
| John Ericson | I recommmend reviewing with ignoring space changes 😓 | 23:42:56 |
| John Ericson | and probably commit-by-commit too | 23:43:04 |

| John Ericson | Alyssa Ross: do you want to add freebsd to release-cross.nix after all your hard work? | 00:27:43 |

 misuzu | In reply to @raitobezarius:matrix.org
PCIe is something quite minimal we want and is still under review with current patchset kernel doesn't see nvme ssd when it's initialized in u-boot, but if boot partition is on sdcard it works fine. I hope this will be fixed soon | 08:39:15 |
 j-k | emilytrau John Ericson anything else in progress for minimal-bootstrap?
Am I right in thinking we're on sysa/run-after-fiwix.kaem at the moment? | 18:46:25 |
| John Ericson | j-k: I am not working on anything, I did my parallelism bit and am done for the moment | 18:47:12 |
| j-k | yeah I pulled the latest copy & it builds very nicely. I'm playing with adding strictDeps to the derivationWithMeta but I imagine how we add extra bits like that will need some discussion
Since it looks like we're on that file I'm probably going to try add tar & gzip in the same vein as gnumake/gnupatch | 18:49:32 |
| John Ericson | j-k: strictDeps is a stdenv thing, derivationWithMeta already lacks unstrictDeps! | 19:19:27 |
| John Ericson | unless I am missing something | 19:19:35 |
| j-k | ah ok got it, I thought it might be a derivation builtin thing. my bad | 19:20:00 |
| j-k | For gzip and tar I'm going to need some replacement files & makefiles from live-bootstrap
https://github.com/fosslinux/live-bootstrap/tree/1bc4296091c51f53a5598050c8956d16e945b0f5/sysa/gzip-1.2.4/files
https://github.com/fosslinux/live-bootstrap/tree/1bc4296091c51f53a5598050c8956d16e945b0f5/sysa/tar-1.12/files
any thoughts on vendoring them in nixpkgs, vs creating .patch files that are equivalent, vs builtins.toFile them in?
| 19:31:56 |
| John Ericson | j-k: there is some fetchurl in there already? | 19:44:03 |
| John Ericson | the fetchurl boot? | 19:44:07 |
| j-k | no fetchurl of the whole of live-bootstrap or individual files from live-bootstrap if that's what you mean | 19:51:48 |
| John Ericson | j-k: I think you could just fetchurl boot a single file from github? | 20:03:29 |
| John Ericson | no compression or archiving to worry about then | 20:03:42 |
 emilytrau | j-k: this is my "sandbox" branch https://github.com/emilytrau/nixpkgs/tree/trusting-trust-next | 22:13:48 |
| j-k | ah very nice.
i'm working on a shell script where we can hopefully build out the sha256s for all the files such as these ones to make maintenance easier:
https://github.com/NixOS/nixpkgs/blob/d6cee7f2d3ef7b5c55a1b1347dbcad7ff660560d/pkgs/os-specific/linux/minimal-bootstrap/gnutar/default.nix#L16-L37 | 22:16:15 |
| j-k | I tried a bunch of stuff that all felt awful to use but this is what I've ended up with:
# This file is generated by ./gen-sources.sh.
# Do not edit!
{
targetCommit = "1bc4296091c51f53a5598050c8956d16e945b0f5";
files = {
"sysa/gzip-1.2.4/files/stat_override.c" = "1216xn1536mfjyx9j1b6128ynb3mfdmy68h7y0n656sk9p5rpf75";
"sysa/gzip-1.2.4/mk/main.mk" = "06c9xl13ym41i2q7rb370kc7affwxbbm6lyqpgbpj6q83bv4dhkq";
};
}
& a default.nix that mapAttrs that into fetched files to be used like
cp ${live-bootstrap-files."sysa/gzip-1.2.4/mk/main.mk"} Makefile
or
cp ${live-bootstrap-files."sysa/${pname}-${version}/mk/main.mk"} Makefile
I'll clean it up and put it on a branch in the morning but any initial thoughts on the UX?
I considered trimming off the "sysa" part but in theory there could be collisions with stuff "sysc"
