Dear,

Currently, the URI scheme (see 'bioconductor-uri' in
guix/build-system/r.scm) is:

 https://bioconductor.org/packages/release/data/<type-url-part>/src/contrib/<upstream-name>-<version>.tar.gz

which leads to 2 issues:

 1. when Bioconductor updates their release, some package versions are
updated too, and so, the upstream return 404.
 2. for this reason 1., the "guix time-machine" is broken for all the
Bioconductor packages, at least if Berlin or SWH does not have a
substitute; which is not expected for 'annotation' packages.

However, the Bioconductor archive still serves the old release, i.e.,

https://bioconductor.org/packages/3.x/data/<type-url-part>/src/contrib/<upstream-name>-<version>.tar.gz


The ways to fix the both issues are:

 a) Add the Bioconductor release (known at packaging time) to all the
packages; provide as argument to 'bioconductor-uri'.
 b) Add more URLs to fallback.

As discussed on IRC, Tobias seems more inclined with the option a) and
I am more in favour of option b.

Attached, a quick patch showing the option b).


Please also consider #36805 which was never merged or closed.

All the best,
simon

I think option a) is more explicit, which is probably what we generally
want to future-proof the time-machine.  Fallbacks are okay in the case
of the CRAN URL where it’s not necessarily clear when a package tarball
moves from the release location to the archive.

In the case of Bioconductor URLs it seems that we can afford to be a bit
more accurate.

We are going for option a) which means rename all the URLs, right?

Because it is a lot, I suggest to first address the bug#36805, i.e.,
provide as an argument the BioConductor version to 'bioconductor-uri'
and applies this policy to all the new packages or any update of them.

Moreover, I have suggested to reorganise bioconductor.scm,
bioinformatics.scm, cran.scm, etc. and I have not dedicated enough
time to this boring task.  But because I am working remotely
(semi-lockdown), I plan to work on it next week and so this change of
URLs could be part of the big reorganisation.

What do you think?

Dear,

The time-machine is broken for some BioConductor packages..  For an
example, consider the package "r-genomegraphs" which has been removed
from the BioConductor in 3.11 release.

(Well, now the issue is mitigated because ci.guix.gnu.org serves a lot
of upstream substitutes but ci.guix.gnu.org could be down.  Other
said, we should use the upstream resources where they are available.)


Concretely, there are 2 issues:

 a) What to do for the removed packages?  For 3.11, the list is there
[1].  Do we keep them in gnu/packages/bioconductor.scm but then
'bioconductor-uri' needs some tweaks?  Or do we transfer them to the
channel guix-past (for example)?

 b) The fallback URI in guix/build-system/r.scm(bioconductor-uri)
added by commit c586f427b4831b9b492e5b900b2226e898b8fcfa is not
correct, if I do not misread:

--8<---------------cut here---------------start------------->8---
"https://bioconductor.org/packages/3.10/bioc/src/contrib/Archive/GenomeGraphs_1.46.0.tar.gz"
404 "Not Found"
--8<---------------cut here---------------end--------------->8---

The correct seems to be (without Archive):

https://bioconductor.org/packages/3.10/bioc/src/contrib/GenomeGraphs_1.46.0.tar.gz


All the best,
simon

About the url, for sure, see attached.

But it does not address the root of the problem.  Well, I will try to

Hi,

Some explanations of the issue are provided here:

    <http://issues.guix.gnu.org/issue/39885>

Since we are currently updating to 3.12, maybe it is the occasion to fix
the issue.  See option a) below.

An example of this issue is for example:

--8<---------------cut here---------------start------------->8---
$ guix time-machine --commit=aee183e -- import cran -a bioconductor CATALYST -r

--8<---------------cut here---------------end--------------->8---

Aside the ugly backtrace which is tracked by #44115, the main issue is
because Bioconductor updated to 3.12 and Guix is still at 3.11.

Concretely, the issue is that ’release’ in the URL:

<https://bioconductor.org/packages/release/bioc/src/contrib/CATALYST_1.12.2.tar.gz>

now refers to 3.12 (because Bioconductor update) and Guix still think it
is 3.11 (because Guix has not yet updated; work-in-progress).  And
CATALYST in 3.12 is at version 1.14.0 against 1.12.2 for 3.11.
Therefore, the conflict and the error.

It means that while:

    (define %bioconductor-version "3.11")

is not updated to 3.12, all the Bioconductor packages are broken; in the
meaning not buildable from source.

Then each time we update Bioconductor, we add an URL to the list.

Tobias and Ricardo are in favor for a) (see this thread).  Which means a
lot of work IMHO, i.e., add 3.11 as arguments and then 3.12 to all the
Bioconductor packages and fix the importer, IIUC; while b) means do
nothing except merge the proposed patch (possibly re-worked).

Just to note that only the task to group in bioconductor.scm all the
Bioconductor packages scattered here and there is still not done, I
think option a) is not doable by hand – I do not volunteer! :-) Else,
any suggestion to script the task instead?

Since I am more in favor of b), I am less motivated to fix the a). ;-)
But I am motivated to fix the issue at hand. :-)


Other option c) is to switch all the Bioconductor to git-fetch instead
of url-fetch.  I have not checked yet how could be the transition.


> Please also consider #36805 which was never merged or closed.

This patch could help for option a).


WDYT?

It is still the case and for concrete breakage, see [1].  I will not
detail but each time Guix lags behind Bioconductor new release, it is
broken.  For sure, Guix upgrades more or less quickly.  Each time
Bioconductor remove a package, it is broken.  Well, because a lot
of care about R packages, the forward breakages happen barely. :-)  But
backward breakages are not negligible, IMHO.


Well, this URL choice is not The Right Thing and somehow broken by design.

We are now 1.5 years after.  And we did nothing; well we did other
things instead. ;-).  Now, I have an strong opinion that option a) is
not doable: I speak using my janitor moves of Bioconductor packages.

Instead, something along the proposed patch below half-fixes the issue
now.  We just have to append the releases and let the fallback mechanism
takes care.  It reduces the maintenance burden, IMHO.

For sure, it is not perfect but it appears to me a pragmatical fix
waiting something better.


This better is unknown (at least from me :-)).  On one hand Disarchive
would improve the situation for tarballs… but some work remains (check
that SWH ingestion and rebuild is bullet-proof).  On the other hand,
Bioconductor uses Git, for instance:

    git clone https://git.bioconductor.org/packages/CATALYST

<https://bioconductor.org/packages/release/bioc/html/CATALYST.html>

And Bioconductor uses ’origin/RELEASE_3.14’ as Git tag.  Based on this,
it would avoid the eternal inplace-change fixes.

For instance, the package tximeta [2], recently updated by Ricardo.
Well, from their Bioconductor Git repo,

    git clone https://git.bioconductor.org/packages/tximeta

it is not clear that the current version is at 1.12.3.  And it is not
clear either if they tagged origin/RELEASE_3_14 at 1.12.0 and did
something ugly to then get 1.12.3.  Anyway, switch from url-fetch to
git-fetch is an option.  However, it is as option a) and I am not
convinced it is doable with the resource at hand.

What could a plan to have a bullet-proof “guix time-machine” for
Bioconductor?


Cheers,
simon
