How Can We Make G-Expressions Even More Interactive At The REPL?
Hi Guixers, How can we make g-expressions even more interactive at the REPL? For example, thing to explore is what can we print instead of '(*approximate*)? Just brainstorming/listing. Let me know if there is some previous thread I should be reading. ps WDYT if we had even more convenience meta-commands for interactive development with g-expressions?

The us-east mirror makes a big difference for me. The wget output is below, but anecdotally, last week, when I installed Guix on a new Debian installation, my first `guix pull` failed maybe three times due to substitute timeouts before I enabled the mirror. After enabling the mirror, it succeed on the first attempt. Tangentially, a few months ago I was using a very poorly connected network that had the additional annoying property of disconnecting every 10 minutes or so. I got stuck downloading the beginning of one large nar enough times that eventually I gave up. I found, though, that `wget -c` was able to complete the download (though it took several attempts). Adding some similar resume functionality might at least help to mitigate the impact of slow downloads. > > France:wget > https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 > US:wget > https://bordeaux-us-east-mirror.cbaines.net/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 > Singapore: wget > https://bordeaux-singapore-mirror.cbaines.net/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 > > > So please share the output from wget and if you're comfortable doing so, > the rough real world location of where the computer doing the > downloading is. > Here are results from Florida, US: philip@avalon:/tmp$ wget https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 --2023-05-25 16:27:53-- https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 Resolving bordeaux.guix.gnu.org (bordeaux.guix.gnu.org)... 185.233.100.56, 2a0c:e300::58 Connecting to bordeaux.guix.gnu.org (bordeaux.guix.gnu.org)|185.233.100.56|:443... connected.

How many bytes do we add (closure of guix) when adding one new package?
Hi, The initial discussion was about the closure of Guix and that “guix pull” brings graphical libraries. See #63050 [1]. Here, I would like to open a discussion about how Guix scales, i.e. about its size. I am trying to answer the question I am asking as the subject. ;-) It’s another angle to view Andreas and Ludo discussion: :-) >> Note that I do not care so much about the closure size, but about the >> number of packages that are needed to just build guix (although of course >> the two are related). Or otherwise said, the dependencies for "guix pull". > > Yes, understood. Graphviz is not in the closure anyway, it’s a > build-only dependency. Somehow, the closure is increasing: --8<---cut here---start->8--- $ for i in $(seq 1 4); do guix time-machine --commit=v1.$i.0 -- size guix | grep 'total:' ;done total: 410.9 MiB total: 496.0 MiB total: 564.8 MiB total: 637.2 MiB $ guix size guix | grep 'total:' total: 611.2 MiB --8<---cut here---end--->8--- (Yeah, the package guix is not exactly the same as guix itself, but it appears to me a good enough approximation. And my current revision is 14c0380.) Compare: --8<---cut here---start->8--- $ guix time-machine --commit=v1.1.0 -- size guix --sort=self | wc -l 44 $ guix time-machine --commit=v1.4.0 -- size guix --sort=self | wc -l 72 $ guix size guix --sort=self | wc -l 70 --8<---cut here---end--->8--- which is the Andreas’s concern for “exotic” architectures.

Re: Understanding a Golang importer error
Hi, On mer., 24 mai 2023 at 19:29, Felix Lechner via "Development of GNU Guix and the GNU System distribution." wrote: > I would find it more consistent, however, to pick a nearby version (or > the newest version) and emit that package definition, instead. Well, what does it mean “nearby“? From my understanding, it seems better to display a warning, to be non-blocking and provide a recipe where the integrity checksum is missing. For an example, see: https://issues.guix.gnu.org/issue/63647#0-lineno61 > After all, Guix package variables do not care about versions, and > neither do we. Guix and its contributors assume more or less > throughout that nearby versions work fine. Why not here, too? I do not understand what it means. Guix package cares a lot about fixed-output, i.e. about the integrity checksum. :-) Quoting the manual: Operations such as file downloads and version-control checkouts for which the expected content hash is known in advance are modeled as fixed-output derivations. Unlike regular derivations, the outputs of a fixed-output derivation are independent of its inputs—e.g., a source code download produces the same result regardless of the download method and tools being used. https://guix.gnu.org/manual/devel/en/guix.html#Derivations Therefore, you need a mean to express the map between the Guix content-addressed and the outside world working with URIs and often with version label. > We could also prompt the user of 'guix import' to select a tag. Well, I know nothing about Go. Neither about how Go packaging is working. Currently, these tags does not seems appearing in the goproxy (https://proxy.golang.org) which is the information used to construct the recipe, IIUC. > Do the versions perhaps come from the consuming go.mod files that > spell out the version requirements? Please note that, as Attila pointed, some improvements [1,2] for the Go importer are waiting for review in the patch tracker. Help is welcome. ;-) 1: https://issues.guix.gnu.org/issue/55242 2: https://issues.guix.gnu.org/issue/63631 Cheers, simon

I correct myself. :-)
See v3 of #63647 which rebases #52362 implementing support of tags.

Ok, sitting in Portland, Oregon, USA, with native IPv4 and IPv6 over a wireguard VPN routed via Freemont, California, USA... I tested both IPv4 and IPv6 for those that have IPv6 (US mirror only has IPv4). There is constant internet activity from other machines on the local network, so a lot of uncontrolled variables... The results seem to be all over the place, with the best speed result france (IPv4), the second best singapore(IPv6), the worst singapore (IPv4) and second worst the US mirror (IPv4), somewhat surprisingly. Maybe fetching the same content over IPv4 followed up by IPv6 warmed up the disk cache on the server side... but clearly not consistently. My VPN is hosted somewhere with much better internet connectivity, so maybe wireguard manages to queue packets and send them more efficiently for the IPv6 connections... sometimes? --2023-05-25 07:55:21-- https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 Resolving bordeaux.guix.gnu.org (bordeaux.guix.gnu.org)... 185.233.100.56 Connecting to bordeaux.guix.gnu.org (bordeaux.guix.gnu.org)|185.233.100.56|:443... connected.

I am located in a home connected via a consumer-grade microwave link from Sail Internet and then via fiber to their hub in Hurricane Electric's FMT2 data center, which is about three miles away. My static IP is 208.82.101.137, or sail-ipv4.us-core.com. Typical downlink speeds are 200-300 Mbps. Thanks for operating and maintaining the Bordeaux build farm! Kind regards Felix
Do substitutes download slowly for you? / Speeding up substitute delivery/mirrors
Hey! I was reminded again about substitute download speeds outside of Europe again today. There was some feedback when I sent out a message to guix-devel [1], [2] a while back. I think the rough summary is that there's anecdotal evidence that a US mirror helps. 1: https://lists.gnu.org/archive/html/guix-devel/2022-05/msg00203.html 2: https://lists.gnu.org/archive/html/guix-devel/2022-07/msg00163.html While I did stop running a mirror in Singapore, it's now back and from the discussion on IRC today [3] there was some anecdotal evidence that this helps with fetching substitutes from China. 3: https://logs.guix.gnu.org/guix/2023-05-25.log#142624 Once again it would be good to gather some data on this, so here are some test commands. I'm interested to see how France compares with either the US or Singapore depending on your location. If you think that none of these locations serve you well, then please say that plus give some indication of what download speeds you see for things that download quickly. France:wget https://bordeaux.guix.gnu.org/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 US:wget https://bordeaux-us-east-mirror.cbaines.net/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 Singapore: wget https://bordeaux-singapore-mirror.cbaines.net/nar/lzip/078vr3r8mn3yrwzwxw64hmcyshic9p3q-stellarium-0.21.0 So please share the output from wget and if you're comfortable doing so, the rough real world location of where the computer doing the downloading is.
