Re: #$(this-package-input "subversion") in git introduces a cycle
Hi Maxim, I am late to the party and maybe it is already solved.

Would someone have an idea? No idea. On a side note, on the top of cd46757c1a0f886848fbb6828c028dd2a2532767, I get this error: --8<---cut here---start->8--- phase `build' succeeded after 17.4 seconds starting phase `build-subtree' error: in phase 'build-subtree': uncaught exception: unbound-variable #f "Unbound variable: ~S" (native-inputs) #f phase `build-subtree' failed after 0.0 seconds Backtrace: In srfi/srfi-1.scm: 634:9 19 (for-each # …) In ice-9/boot-9.scm: 1752:10 18 (with-exception-handler _ _ #:unwind? _ # _) In guix/build/gnu-build-system.scm: 929:23 17 (_) In ice-9/boot-9.scm: 142:2 16 (dynamic-wind # …) In ice-9/eval.scm: 619:8 15 (_ #(#(# (# # … In ice-9/boot-9.scm: 1752:10 14 (with-exception-handler _ _ #:unwind? _ # _) In ice-9/ports.scm: 433:17 13 (call-with-input-file _ _ #:binary _ #:encoding _ # _) In guix/build/utils.scm: 899:26 12 (_ #) 959:29 11 (loop "\t$(XMLTO) -m $(MANPAGE_XSL) $(XMLTO_EXTRA) man …") In srfi/srfi-1.scm: 460:18 10 (fold # …) In ice-9/eval.scm: 202:51 9 (_ #(#(#(#(#(#(# …)) …) …) …) …)) 163:9 8 (_ #(#(#(#(#(#(# …)) …) …) …) …)) 163:9 7 (_ #(#(#(#(#(#(# …)) …) …) …) …)) 159:9 6 (_ #(#(#(#(#(#(# …)) …) …) …) …)) 293:34 5 (_ #(#(#(#(#(#(# …)) …) …) …) …)) 223:20 4 (proc #(#(#(#(#(#(# …)) …) …) …) …)) In unknown file: 3 (%resolve-variable (7 . native-inputs) #) In ice-9/boot-9.scm: 1685:16 2 (raise-exception _ #:continuable? _) 1685:16 1 (raise-exception _ #:continuable? _) 1685:16 0 (raise-exception _ #:continuable? _) ice-9/boot-9.scm:1685:16: In procedure raise-exception: Unbound variable: native-inputs --8<---cut here---end--->8--- And it probably comes from: (search-input-directory (or native-inputs inputs) (string-append "xml/xsl/docbook-xsl-" #$(package-version docbook-xsl))) Maybe it is related to the error you observed later. Hum, I do not know… I have not investigated further. :-) Cheers, simon

Last time I checked, zstd with max compression (zstd --ultra -22) was a little slower and had a little lower compression ratio than lzip with max compression (lzip -9). Zstd is however much faster for decompression. Another thing that could be useful to consider is that lzip was designed for long term storage, so it has some redundancy allowing fixing/recovering a corrupt archive (e.g. using lziprecover) if there has been some bit rot in the hardware storing the file. Whereas as far as I know zstd will just tell you "error: bad checksum" and will have no way to fix the archive. signature.asc Description: PGP signature
RISC-V builds and substitutes
Hey, I have a RISC-V board that is hooked up to the bordeaux build farm, and there is another board connected, although there's some issues with the connection/agent. 1 to 2 boards though isn't enough to get good substitute availability and build packages for patches and branches though. There's now HiFive Unmatched Rev B boards available [1], so is there interest in buying additional boards for the project so that we can improve substitute availability and get QA doing RISC-V things? 1: https://www.sifive.com/blog/unlock-the-possibilities-with-hifive-unmatched-risc-v Chris signature.asc Description: PGP signature

For me, the priority list looks like: I'd like to have a single archive type as well in the future, but I'd settle on Zstd, not lzip, because it's faster to compress and decompress, and its compression ratio is not that different when using its highest level (19). > 1.

That'd be nice, but not presently doable as we can't fine tune retention for a particular 'derivation' and its inputs in the Cuirass configuration, unless I've missed it. -- Thanks, Maxim

Guile's syntax features make the code more > symbolic and less approachable to newcomers. just FTR, i don't think that the guix codebase is too bad in this regard. here i just wanted to remind people to the not so obvious cost of syntactic abstractions that should be accounted for when making decisions. introducing macros that generate macros is rarely justified. in general, it's *very* valuable when stuff can be grep'ped -- and not only for newcomers. after enough time has passed i can feel like a newcomer to my own codebase... :) modulo the protocols that i keep while writing code. e.g. define.*whatever is a grep that i regularly employ. the pattern here is that although there are countless ways to define countless different stuff, there's a convention to stick to the define.*[name] pattern. intuitive, unique (i.e. grep'pable) names are also key to facilitate code approachability, especially for abstractions that are scattered around in many source files. in some situations i even copy-paste names of abstractions into comments for any future grep'ping to pick it up. a negative example for this in the guix codebase is the use of 'service' to describe two rather different abstractions: a component of an OS vs. a deamon process run by shepherd. for a while it caused me quite some confusion. -- • attila lendvai • PGP: 963F 5D5F 45C7 DFCD 0A39 -- “The State is that organization in society which attempts to maintain a monopoly of the use of force and violence in a given territorial area; in particular, it is the only organization in society that obtains its revenue not by voluntary contribution or payment for services rendered but by coercion.” — Murray N.
