Hi,

Using Guix 55685e4, I get:

It is probably an upstream in-place replacement.

All the best,

Hi,

the checksum was corrected by Tobias Geerinckx-Rice in commit 20771f4043990632b73187b10d1851a1244df4e6 as well as the pkg was updated from 2.10 -> 2.11.

Indeed, when looking forward. :-)

However, in the context of Disarchive and long-term, it is seems
relevant to keep it still open; as example to test “guix time-machine”
and various fallbacks, IMHO.

I'm also curious to know to fill in the archive for old versions. I guess
the first step would be to preserve the tarballs with the original hashes.
Does anyone have them? I notice that this happened again with 2.17:

fossil-src-2.17.tar.gz 6.0MiB 4.0MiB/s 00:02 [##################] 100.0%
sha256 hash mismatch for /gnu/store/i695w5hp8vkgvkx40rs8p647mas0ldah-fossil-src-2.17.tar.gz:
expected hash: 1gvx6xzrw1a8snlq9qmr6099r44ifghg0h0fw4jazqmmyxriqzsw
actual hash: 18q5rc1d9d2zvrvsas5h419dv525ig9lyqswrx7bcl38zbjxics4

Looking forward:

I have asked upstream how we might avoid this problem:

We'll see what they say.

Some other ideas in the meantime:

1) Develop a fossil-fetch that can be used like git-fetch to download from
the source code repository directly.

2) Use git-fetch with the git-mirror. This would allow us to make use of
our current git integration with Software Heritage.

Best,
Jack

I got a substitute for the tarball:

Toggle snippet (12 lines)
$ guix build "/gnu/store/svcwny2aw005mgyz7fsnm8m7v612q9d4-fossil-src-2.17.tar.gz.drv"

1gvx6xzrw1a8snlq9qmr6099r44ifghg0h0fw4jazqmmyxriqzsw

Alternatively, we can get it via the content-addressed endpoint:

Toggle snippet (4 lines)
$ wget -qO- https://ci.guix.gnu.org/file/fossil-src-2.17.tar.gz/sha256/1gvx6xzrw1a8snlq9qmr6099r44ifghg0h0fw4jazqmmyxriqzsw |guix hash -
1gvx6xzrw1a8snlq9qmr6099r44ifghg0h0fw4jazqmmyxriqzsw

Last, Disarchive tarball metadata is available:

Toggle snippet (15 lines)
$ wget -qO- https://disarchive.guix.gnu.org/sha256/$(guix hash -f hex $(guix build "/gnu/store/svcwny2aw005mgyz7fsnm8m7v612q9d4-fossil-src-2.17.tar.gz.drv")) |head

(swhid "swh:1:dir:1d10cd5c9e0afaf7c95fa87cd50d4b6b13e6c6c9"))

… and tarball content is in Software Heritage:


So we’re doing OK: it’s definitely archived and won’t ever vanish! :-)

That's great!

I guess I ran into this because I was using `guix build` with
`--no-substitutes`. Is it expected that we don't fallback to disarchive
and Software Heritage in that case? If so, I guess my problem was an
operator error. Can we close this ticket then, or are we still missing the
tarballs for the older releases?

Best,
Jack

Yes, and that’s actually suboptimal:

We would need to check whether older releases are available. Disarchive
is relatively recent so they’re likely to be missing there, but Timothy
Sample has a Disarchive database that goes several years back, unlike
disarchive.guix.gnu.org. Worth checking!

Anyhow, I think this issue can be closed.

I guess the Timothy’s database starts on 2019-05-05 which is v1.0. The
last coverage is from Jan 2022.
