guix refresh to a specific version?

guix refresh to a specific version?

[Hartmut Goebel]

Hi,

I wonder whether this is a way to refresh to a specific version, like 
one can import a specific version:

works:

     guix import pypi trytond@6.2.0

does not work:

     guix refresh -u trytond@6.2.0
     […]
     guix refresh: error: trytond: package not found for version 6.2.0

My use-case is to update 170 trytond modules from 6.0.x to the 6.2.x, 
while 6.4 is current. (I have a list of exact versions, thus being able 
to specify a discrete version is fine.)

It’s currently not possible, but pretty much all the machinery is there,
in importers.  It’s a low-hanging fruit that I think we should pick!

I gave it a try and discovered that we need to discuss the interface and 
design:

One can already specify a version, which defines the package to be 
updated. The respective place the code has the comment

Take either the specified version or the latest one.

and this was added by you (Ludo) in 
4b9b3cbbc45afa3e374889847d4ab8673b8b2db2 (April 2015):

refresh: Allow users to refer to specific package versions.

* guix/scripts/refresh.scm (guix-refresh): Use 'specification->package'
   instead of 'find-packages-by-name'.  This allows users to specify
   things like "qt-4.8.6".


Beside this, I'm unconfident about the implementation: Currently refresh 
passes around package objects and passes this to the updater. When 
updating to a specific version, we need to pass around both the package 
and the desired version, which implies case-handling at many places. Any 
idea how to solve this elegantly?

Like you write, this commit is the “wrong end”: it’s about selecting the
package you’re willing to update.

Most entry points in (guix import …) already take a #:version parameter,
which allows you to ask for a specific version when running ‘guix
import’, as in:

  guix import pypi itsdangerous@1.1.0

The goal here is to expose that in the <upstream-updater> API and to use
it in ‘guix refresh’.

FYI: I'm working on this. Given the number of importers and updaters is 
just takes some time.

Excellent.  If you want, you can ping me for early comments on the
<updater> API for this.

Thanks for offering this, I appreciate.

I pushed my current working state to wip-import-version. The branch also 
contains some patches from bug56295 (Add some Chicken eggs and fix egg 
importer) and bug56318 (Fix github updater).

Basic ideas

  * Add a keyword argument „version“ to all “latest-X-release” functions
    and eventually pass it on to called functions.
  * Minimal changes

Here is a list of updaters and packages to test the import-specific-version:

+crate: rust-sequoia-openpgp@1.7.0
+egg: testing requires new packages (see bug56295),
       changing version of “chicken-args” to 1.6.0 in chicken.scm and
       test updating to chicken-args@1.6.1
+generic-git (import/git): remmina@1.4.25
+generic-html (gnu-maintenance): xclock@1.1.0
+github: libwacom@1.12
+gnome: gtk@4.6.2
+gnu (gnu-maintenance): help2man@1.49.1
+gnu-ftp (gnu-maintenance): libgpg-error@1.43
+hexpm: testing requires changing version in erlang.scm
        erlang-relx to 4.5.0 and test updating to erlang-relx@4.6.0
+kde: plasma-framework@5.93.0
+kernel.org (gnu-maintenance) = html: iw@5.3
+launchpad: testing requires changing version in terminals.scm
            sakura to 3.8.0 and testing upate to sakura@3.8.3
+pypi: trytond-party@6.2.0
+savannah (gnu-maintenance) = html: libpipeline@1.5.4
+xorg (gnu-maintenance) = ftp : libxi@1.7.99.2


These updaters report an error that they can't update to a specific 
version, if a version is given:

?bioconductor (cran.scm) -- repo supports latest version only
?cran -- repo supports latest version only
           old version available in
https://cran.r-project.org/src/contrib/Archive/PACKAGENAME
-cpan  --- no version, not recursive
-elm  -- no updater
-elpa  --- no version
-gem  --- no version
-hackage  --- no version
-minetest  --- no version
-opam  --- no version
-sourceforge (gnu-maintenance) -- to complicated
-json  -- n/a
-texlive  --- no version, not recursive, no updater

Not yet implemented — unclear how to handle:

# stackage  --- LTS version

Still missing:

  * Finishing commit messages
  * Documentation?
  * For the final commit, I'll squash the commits.

Hi,

Thanks for working on this.

It is indeed a limitation of the Bioconductor importer and the issue is
discussed here:

    http://issues.guix.gnu.org/issue/39885
    http://issues.guix.gnu.org/issue/54787

For me, doing s/http/https/ on above, then
--8<---------------cut here---------------start------------->8---
    firefox-esr 'https://issues.guix.gnu.org/issue/39885' &
--8<---------------cut here---------------end--------------->8---
seems to connect ok.

Just wondering if you are posting these as "http" links for some
hidden reason :)

They should even redirect from http: to https:, and here they do.

Because my Emacs helper [1] still uses 'http'.

Neat!

For clarity I would rename the ‘latest’ field of <upstream-updater> to
‘import’ (say), likewise for the ‘latest-*-release’ procedure.

I suspect most of them could be change to fetch a specific version, but
that can come later.

I’ll be monitoring guix-patches for the final version.  :-)

Thanks!

It took some time, and here it is: https://issues.guix.gnu.org/57460

FWIW, this works for the 'crate' importer.
