This patch adds a new ‘generic-git’ updater which can check for new tags
for package hosted on Git repos. However, it cannot download Git repos
and update the package definitions, i.e. ‘guix refresh -u’. There is a
pending patch that would add this feature though[1].
‘guix refresh -L’ now reports
Available updaters:
[…]
94.5% of the packages are covered by these updaters.
We are getting close to 100% :-)
See it in action!

Hello,
Thanks for the patch! Glad to see this idea becoming more polished.

FWIW, harmonist and a few other packages fail to work because they use
an old git protocol which is not supported by libgit2.

I do like the selection of (prefix, suffix, delimiter), though I think
there are only one or two packages which use a different delimiter.

(string-split* "1:2.3" ":.") -> ("1" "2" "3")
(string-split* "1a2b3" "ab") -> ("1" "2" "3")
Is this what you intended? The documentation above makes it sound like
the whole string serves as the delimiter.
> +

PACKAGE is not used by this procedure.
> + (define delim* (if delim delim "."))
> + (define prefix-regexp "^[^0-9]*")
> + (define suffix-regexp (string-append "[^0-9" (regexp-quote delim*) "]*$"))
With a delimiter of '.', this would say the suffix of '1.2.3.prerelease'
is 'prerelease', not '.prerelease'. Is this correct? (I would be
tempted to just remove delim* from this.)
> + (define delim-regexp (string-append "^[0-9]+" (regexp-quote delim*) "[0-9]+"))
This fails to account for versions which use non-numerics, such as (all
taken from the package-version field of packages using git-fetch and
which use this version as the tag):
1.0.0-beta.0
0.0.9.4f
4.4-git.1
5.2.0-alpha
0.2.0-alpha-199-g3e7a475
20200701.154658.b0d6223
12-068oasis4
4.0.0.dev8
0.32-14-gcdfe14e
2.8-fix-2
There are about 50-60 packages like this.
I'm not sure how much effort should be spent including them, and for
some of them I'm not sure what our ideal behavior *is*. Even if we
could reliably detect them, should "alpha" or "dev" packages be returned
by the updater?
Upon investigation, there is a deeper problem: version-compare thinks
"5.2.0" is a lower version than "5.2.0-alpha", and that "4.0.0" is lower
than "4.0.0.dev8".
scheme@(guile-user)> (version-compare "5.1.9" "5.2.0")
$5 = <
scheme@(guile-user)> (version-compare "5.2.0" "5.2.0-alpha")
$6 = <
scheme@(guile-user)> (version-compare "4.0.0" "4.0.0.dev8")

This throws an error if the version doesn't have any delimiter.
Actually, it throws an error in a lot of other cases too, often saying
the 'tag-version-delimiter is wrong when it's something else. Consider
the tags from the "openjpeg" package, sorted by 'sort-tags':
arelease
opj0-97
start
v2.1.1
v2.1.2
v2.2.0
v2.3.0
v2.3.1
v2.4.0
version.1.0
version.1.1
version.1.2
version.1.3
version.1.4
version.1.5
version.1.5.1
version.1.5.2
version.2.0
version.2.0.1
version.2.1
wg1n6848
At first, 'get-version' throws an error because "wg1n6848" doesn't have
a delimiter. But even disregarding that, it would return "version.2.1"
-> "2.1" as the latest version.
Probably we should process all tags with 'get-version' (simply skipping
any that don't parse) and use that to sort the tags. If none parse with
'get-version' we could use the "no tags" error or have a separate error
for "there were tags but we couldn't process them".
And this lets us just do something like (untested):
(define* (get-version tag #:key prefix suffix delim)
(define delim-rx (regexp-quote (or delim ".")))
(define prefix-rx (or prefix "[^[:digit:]]*"))
(define suffix-rx (or suffix ".*"))
(define version-char-rx
(string-append "[^" delim-rx "[:punct:]]"))
(define tag-rx
(string-append "^" prefix "(" version-char-rx "+("
delim-rx version-char-rx ")*)" suffix-rx "$"))
(and=> (string-match tag-rx tag)
(cut match-substring <> 1)))
Though at this point, 'tag-rx' should probably be constructed and
compiled outside the loop.

We surely don't want 'update-cached-checkout' since that fetches the
whole repo history! I've attached a patch below (based on top of this
one) which brings the total time-per-package to under 1s. I moved it to
(guix git) to make use of 'with-libgit2' which ensures we use system
certificates.
Apologies for such a long reply. I hope it was helpful :)

It’s not what I wanted, indeed. I will try to fix it.

Good catch, it was some leftover I forgot to remove.

Good point, I think removing ‘delim*’ would be a good idea.

I don’t think we usually include alpha or rc releases, so updater
probably shouldn’t return them either. Not sure how we would try to
detect alpha/beta/rc releases, though, besides running something like
(string-match? "(alpha|beta|rc|dev)" TAG)
On each tag.

Maybe we should filter the tags before comparing them; that should
get rid of these pre-release tags.

Setting the ‘tag-version-delimiter’ prefix to an empty string would
solve this, right? Or, maybe we should just get rid of the delimiter
thing since only a few packages use a different delimiter.

Ah, yes, that would be a good idea.

This wouldn’t match anything if the version is just a plain number,
e.g., 1 or 09.

With this, something like “1.4.0rc1-450-g2725ef99d” will result in
“1.4.0” being returned, which is incorrect. Changing (cut
match:substring <> 1) to just ‘match:substring’ would solve the issue,
but then pre-release tags, which we usually don’t want, would also get
matched. Not sure what the best option would be in this case.

For some reason it seems to include refs that do and don’t end with

It does, but I had many errors in the definition. Again, apologies. I
shouldn't send emails that late, haha. This method should read:
--8<---------------cut here---------------start------------->8---
(define* (get-version tag #:key prefix suffix delim)
(define delim-rx (regexp-quote (or delim ".")))
(define prefix-rx (or prefix "[^[:digit:]]*"))
(define suffix-rx (or suffix ".*"))
(define version-char-rx
(string-append "[^" delim-rx "[:punct:]]"))
(define tag-rx
(string-append "^" prefix-rx "(" version-char-rx "+("
delim-rx version-char-rx "+)*)" suffix-rx "$"))
(and=> (string-match tag-rx tag)
(cut match:substring <> 1)))
--8<---------------cut here---------------end--------------->8---

With the fixed method above:
scheme@(emacs-guix)> (get-version "8")
$16 = "8"
scheme@(emacs-guix)> (get-version "1.4.0rc1-450-g2725ef99d")
$17 = "1.4.0rc1"
But, we still get:
scheme@(emacs-guix)> (get-version "1.4.0-rc1")
$18 = "1.4.0"
which leads us to what you talked about in your other message.

Sorry, another typo I missed. See above.

That heuristic is pretty good. (It might miss a few, but I'd rather
accidentally include some alpha/beta/rc releases than risk excluding
real ones.)
We could then safely sort tags with just the prefix removed -- this takes care
of "1.1f" coming after "1.1", and so on.
Actually, it looks like there's only a few packages with a suffix;
instead, we can probably just only use a suffix if they provide
'tag-suffix. This is all of them (and the "dev" ones probably shouldn't
be suffixes, just part of the version):
(commit (string-append "v" version "-stable"))))
(commit (string-append version "-stable"))))
(commit (string-append version "-Leia"))))
(commit (string-append "haddock-" version "-release"))))
(commit (string-append "v" version "-8.13"))))
(commit (string-append "v" version "-oss"))))
(commit (string-append "v" version "-stable"))))
(commit (string-append "ddskk-" version "_" code-name))))
(commit (string-append version "-freebsdport"))))
(commit (string-append version "-dev"))))
(commit (string-append version "-release-20210531143054"))))
(commit (string-append version "-release-20210412001032"))))
(commit (string-append "v" version "-debian"))))
(commit (string-append version "dev"))))
(commit (string-append version "_Linux"))
(commit (string-append version "R"))))
(commit (string-append "jdk-" version "-ga"))))
(commit (string-append "jdk-" version "-ga"))))
(commit (string-append "jdk-" version "-ga"))))
(commit (string-append "jdk-" version "-ga"))))
(commit (string-append version "-opt"))))
(commit (string-append "1.1-" version "-RELEASE"))))
Additionally, these are all the weird version strings I could find that
are actually used as the commit:

Yep, it looks like the above would work for the majority of these.
That's probably Good Enough^tm.

IMO, just get rid of the delimiter. If we wanted to be *that* flexible,
we could make it so they provide a tag->version proc instead of (prefix,
suffix, delimiter).

Yeah, I think that sounds like a reasonable thing to do.

a ‘tag->version’ procedure would probably make things a bit too
complicated for the people writing package definitions. For example,
having a delimiter would make it easy to match a tag like
“2021-01-01-release”
Delimiter is “.” (sorry if this hurts your eyes ;-))
scheme@(guile-user)> (match:substring (string-match "^[^0-9]*([^\\.[:punct:]]+(\\.[^\\.[:punct:]]+)*).*$" "2021-01-01-release") 1)
$28 = "2021"
Delimiter is “-”
scheme@(guile-user)> (match:substring (string-match "^[^0-9]*([^-[:punct:]]+(-[^-[:punct:]]+)*).*$" "2021-01-01-release") 1)
$29 = "2021-01-01-release"
And then, setting the suffix to “-release” would match just the version
part.

Hmm, maybe we could check that if (string-append "1.4.0" suffix) is a
suffix on of the tag, or is this too much overhead? This would only
work if we set the suffix to the empty string by default.
Since (string-match "1.4.0$" "1.4.0-rc1") returns #f, this tag would get
filtered out. But then a suffix would have to be specified to match
"1.4.0rc1-450-g2725ef99d".
Not sure what the best option is here.

This monstrosity:
rg -U -B4 --pcre2 '(?!\(let.*(\n.*){0,1})\(version "([^\n"]*[^0-9\.][^"\n]*)".*(\n.*){0,10}commit.*version' gnu/packages
and to show just the versions:

Right. I missed that.
In that vein, should we keep the dashes in "2021-01-01" or convert them
to periods? What about when a tag has underscores?
What if a repo has tags in both formats? Then "3.0.1" would be
considered older than "2011-01-01".
Maybe we should just add an extra bit to detect a date format and only
consider it when there's no "proper versions"?
Aaaand I fell down a rabbit hole after that :) I've attached a patch
with what I've done. It still has lots of issues--it requires the tag
to contain at least one version delimiter, it requires the first
character of the version to be a number... it might not even be better
than before I touched it, and even so the added complexity might not be
worth it. But if you'd like to take it for a spin, I've attached it (it
applies straight on master).

Having periods would be more consistent, then could have a
‘date->version’ procedure that replaces the hyphens with dots and have
(git-reference
(url "https://git.example.org")
(commit (date->version version)))
> What about when a tag has underscores?
Hmm, not sure about that, below is a list of packages I could find which had
underscores as delimiters
gnu/packages/graphics.scm
239: (commit "DIRECTFB_1_7_7")))
gnu/packages/gstreamer.scm
326: (commit "ESOUND_0_2_41")))
gnu/packages/java.scm
13925: (commit "jboss-transaction-api_1.2_spec-1.1.1.Final")))
They all seem to use periods in the ‘version’ field, though, so I would
say that the underscroes, should also be converted to periods.

That’s tricky, there isn’t really a way to know how old “3.0.1” is,
without looking at the metadata of the tag. Maybe this is one of those
corner cases which can’t really automatically determine the latest
release. Should we have a ‘no-refresh?’ property to tell the refresh to
not try to update the package?

That could be a good idea!

Great! I will try it out and see how it compares to my current WIP
version.
Not having characters in the first version number probably isn’t such a
big deal, most version that contain characters end with a character.
E.g., “1.2.3a” is not to uncommon, but “a1.2.3” is rarely seen.

These numbers seem rather arbitrary, how did you arrive at them?
Also, AFAICS, versions without delimiters won’t be matched.

This would only match lower-case characters, but sometimes upper-case
characters are used.

I made some changes, to the patch and ran ‘guix refresh -t generic-git |
grep "^gnu/packages.*no valid’; I also modified the ‘github’ updater so
that it wouldn’t be used.
(define %github-updater
(upstream-updater
(name 'github)
(description "Updater for GitHub packages")
(pred (const #f)) ;this right here
(latest latest-release)))
Attached is a file with all the packages that didn’t have any valid
tags, and with a short description of perharps why no valid tags were
found.
Something I noticed was the a lot of Julia package use a version scheme
like this:
(version "1.2.3+0")
The "+0" is included in the version field and acts like a “revision”; I
am not familiar with the Julia ecosystem, and I am not sure how we
should handle this situation.
The updated patch is also attached.

Very nice. Perhaps s/tag-/release-tag-/ for clarity?

To remain consistent with existing naming conventions, I’d call it
‘remote-refs’.

Too bad we need to create an empty repo; hopefully it costs next to
nothing though.

Use ‘filter-map’.

Please add a docstring and remove ‘get-’ from the name. :-)

Leftover? (Also display + format.)
Please spell out ‘delimiter’ (info "(guix) Formatting Code").

That’s a fancy heuristic. :-)

It’s perhaps clearer written like this:
(stable-sort (filter-map (lambda (tag)
(let ((version (get-version tag)))
(and version (cons version tag))))
tags)
entry<?)
> +(define* (get-latest-tag url #:key prefix suffix delim pre-releases?)

Maybe “the tag corresponding to the latest version”.
s/get-latest-tag/latest-tag/
> + (define (pre-release? tag)
> + (any (lambda (rx) (regexp-exec (make-regexp rx regexp/icase) tag))

Better call ‘make-regexp’ only once; so you could change
‘%pre-release-words’ to be a list of regexp objects instead of a list of
strings.

Maybe s/refresh-pre-releases?/accept-pre-preleases?/
Since this procedure takes a package, it probably doesn’t need the other
arguments: it can extract them from the package properties, rather than
doing it at the call site.

Simply: (and new-version (upstream-source …)).
It would have been nice to have tests. I think testing
‘latest-git-release’ should be feasible without too much hassle using
the (guix tests git) infrastructure, as is done in tests/git.scm, with a
package referring to a locally-created repo using a git-reference with a
file:// URL.
Could you send an updated patch?
Thanks,
Ludo’.

Changes since v1:
* Add ‘remote-refs’ procedure to (guix git) (written by Sarah
Morgensen). Add tests for it too.
* Make the updater try to guess the delimiter if none was provided (also
written by Sarah).
* Honor the ‘accept-pre-releases?’ property to include pre-releases when
looking for tags.
* Various regexp improvements.
* Add tests for the updater.
* Some fixes to (guix tests git).
Xinglu Chen (3):
tests: git: Don't read from the users global Git config file.
tests: git: Make 'tag' directive non-interactive.
import: Add 'generic-git' updater.

Without this, Git would try to sign the commits when running
tests/git.scm, this was beacuse I had set ‘gpgSign = true’ in
~/.config/git/config. Setting the environment variable would remove
this impurity.

When running 'git tag TAGNAME', Git will open up the user's default text
editor to make them write a message. This is not desirable when running
tests.
* guix/tests/git.scm (populate-git-repository): Make the 'tag' directive take
an additional argument, and pass it to the '-m' flag.

LGTM, but you need to update at least tests/channels.scm accordingly.

I think that for each of these tests that uses the ‘git’ command under
the hood, you’ll need something like what ‘tests/git.scm’ does:
(unless (which (git-command)) (test-skip 1))
(test-equal …)
It’d admittedly annoying to have this boilerplate, but I can’t think of
a better solution.
Could you send an updated version? Then we’ll be all set!
Thank you,
Ludo’.

Overall this is looking good. Thank you for adding tests (for remote-refs as well!), much appreciated. It looks like you've done some good polishing. I see a few nits, which I'll point out in a separate email when I'm not on mobile. I'll also give it a good test.
But... I've been thinking about the overall approach for a couple days, because I'm not very happy with the complexity of my heuristic.
There can be a lot of weird tags in a repository--look at the one for xf86-video-intel for example. My heuristic attempts to capture the assumption that repostories tend to move from using "_" or "-" to "." but it does fail to account for moving to or from dates (because dates don't compare with normal versions).
I also realized that we are not using a very useful piece of information--the previous version/tag combo. I expect that in the vast majority of cases, the version delimiter for the newest version will be the same as the version delimiter for the last known version. (Perhaps the prefix as well?) Can we use this information to make our guesses better? What do you think?
Despite saying all that, it's probably better to not try to get it perfect on the first go--we can always adjust the internals later. We just want to avoid showing bogus updates.
(Later, I think I'll put together a dataset of tags and current versions to see if I can test how well a particular algorithm works.)

But if a repo moved from using versions to tags, or vice-versa, we still
wouldn’t know if say “3.0.1” is newer than “2021.03.02”. We would have
to know when the “3.0.1” tag was created.
Maybe we could have a ‘release-tag-date-scheme?’ property, that way we
could just try to match dates?

That sounds like a good idea. What should happen if the delimiter from
the previous version/tag combo is different from the one that the
‘guess-delimiter’ procedure returns? Should the one from the previous
version/tag combo take precedence.

Yeah, we can always improve things later.

Cool, looking forward to that. :-)

I discovered that this can segfault unless 'remote-disconnect' and
possibly 'repository-close!' are called *after* copying the data out.
I've attached a diff for this.

One issue with returning a different delimiter than the package
currently uses is that the automatic updater won't really work as-is.
Hmmm. When things are modified so the updater gets both the version and
the git-reference, it should be able to reverse-engineer things well
enough there.
I imagine this is really only going to be an issue with dates currently
written as "2017-01-01", anyway. I'll put my comments on that in reply
to the other email.

This returns two values (in preparation for the above-mentioned switch),
so maybe something like "Return the latest version and corresponding tag
available from..."

Should be "cute" so string-length is only evaluated once -- though it's
probably optimized like that anyway.

I tested this updater on all packages in .scm files starting with f
through z, and I found the following packages with possibly bogus
updates:
--8<---------------cut here---------------start------------->8---
javaxom
luakit
ocproxy
pitivi
eid-mw
libhomfly
gnuradio
welle-io
racket-minimal
milkytracker
cl-portal
kodi-cli
openjdk
java-bouncycastle
hurd
opencsg
povray
gpsbabel
go
stepmania
ocaml-mcl
many minetest packages (minetest will have its own updater, though)
ocaml4.07-core-kernel, ocamlbuild and many other ocaml packages
(they seem to be covered by the github updater)
--8<---------------cut here---------------end--------------->8---
The following packages suggest a version -> date update, which may or
may not be bogus:
--8<---------------cut here---------------start------------->8---
cataclysm-dda
autotrace
lbalgtk
nheko
libqalculate
cl-antik
cl-antik-base
cl-hu.dwim.stefil

You're right; I thought of that afterwards.

That seems like it might be the only way to handle it in some cases (if
they have both versions and dates with a "." delimiter). (Though, we
are actually interested in the *lack* of a date scheme. If they use a
date scheme now, other versions will be disregarded, so we're fine; but
if they use versions now and used a date scheme before, the versions
will be discarded.)

Consider:
prefix := 'tag-prefix or guess-prefix-from-current-version+tag or default
delim := 'tag-delim or guess-delim-from-current-version+tag or guess-delimiter
suffix := 'tag-suffix or default
This should cover:
1. Format stayed the same (including date formats)
2. Format changed from (git-version ...) to proper version
This does not otherwise cover a complete change in format, such as "_"
-> ".", date(-) -> version, or version -> date(.), for which I could
argue requiring a manual update is reasonable. It also does not cover
when the tags have both versions and dates with the same delimiter.
Though it would be nice to see when such updates are available, is it
worth some bogus results? Are false positives better or false negatives
better?
Unless you/we want to pursue one or both of the above changes now, the
latest patch LGTM (modulo my nits).
Thanks for your work,

It doesn’t have to be “.” delimiter though; if they both have the same
delimiter it would be difficult to distinguish a version from a date,
e.g., “1-2-3” vs “2021-03-23”.

I am not sure what you are trying to say, could you elaborate?

Yeah, it’s not really possible to automatically detect those kind of
changes.

Hmm, good question! If in the future we have some kind of bot that
automatically runs ‘guix refresh -u’, builds the updated package, and
send a patch to the mailing list, not having false positives might be
more important. We could also have a ‘disable-tag-updater?’ property to
disable the updater for packages which gives false positive, or maybe
that will result in to many properties.

I would prefer to wait a bit with the improvements mentioned above. The
current patch has been in the works a week or two already, so it’s
probably a good idea to get it merged, and try to solve the less
important issues later. :-)

You are welcome! And thanks for taking the time to test and review the

That’s probably a good idea, since it is related to how the tag will be

That does look cleaner, thanks for the suggestion!

I assume you meant ‘java-xom’ :-)
That’s a weird scheme; setting the delimiter to “.” doesn’t help since
it thinks that “127” is greater than “1.3.7”.

‘pitivi’ has a pretty weird version string to begin with; it may be
better to change it to the date: “0.999.0-2021-05.0” -> “2021-05.0”.

Hmm, ‘guix refresh’ says that ‘ocamlbuild’ is already the latest
version. But you are right, many of the packages are already taken care
of by the ‘github’ updater.

Sure, but I haven't seen the former :)

Just that the important case is disallowing dates when
'release-tag-date-scheme? is #f.
If the tags of a repo are:
12.1
12.2
13.0
13.4
2018.01.01
2018.05.05
and we do nothing, the 2018.05.05 tag will be selected. This is correct
if we do want dates, but incorrect if we don't (in which case we would
set 'tag-version-date-scheme? to #f to get the correct result).

For these packages, it would probably easier to just use the existing
tag- properties. In fact, instead of this or the date-scheme above,
a 'tag-version-regex' would cover both cases.
In fact, we could replace 'tag-version-delimiter' with
'tag-version-regex' and instead provide convencience functions such as
(untested):
(define (version-regex delim)
(let ((delim-rx (regexp-quote delim)))
(string-append "([[:digit:]][^" delim-rx "[:punct:]]*"
"(" delim-rx "[^[:punct:]" delim-rx "]+)"
(if (string=? delim-rx "") "*" "+"))))
(define* (version-date-regex (delim "."))
(let ((delim-rx (regexp-quote delim)))
(string-append "([0-9]{4}" delim-rx "(0[1-9]|11|12)"
delim-rx "(0[1-9]|[1-2][0-9])")))
WDYT?

Sorry, yes, that's what I meant, or "Return true if the origin..."; I
was just suggesting making it a full sentence.

'tag-version-regex would allow fixing this ;)

I'm glad to see that these are easily fixed with the properties, though!
That's some good validation.
Now I just have to give the (guix upstream) some attention...

Changes since v2:
* Address the feedback by Ludovic and Sarah.
One problem I noticed was that when ‘accept-pre-releases?’ is #t, a tag
like “1-2-3-alpha” would turn into “1.2.3.alpha”, but I think the
correct version string would be “1.2.3-alpha”.
I solved the problem by making the pre-release part a separate regexp
group, and then appending the pre-release part after extracting the
version from the tag. That way, the “-” in “-alpha” would not be
interpreted as a version delimiter. I also added a new test for testing
this.
One of the tests in tests/channels.scm is failing; I am not sure why.
Before the first and second patches were applied, 6 of them were failing
for me, so I guess it’s an improvement. However, on IRC, Ludovic said
that all of them were passing (prior to apply my patches). It would
be great if people could run the tests before and after applying
patches, and see if they pass.

When running 'git tag TAGNAME', Git will open up the user's default text
editor to make them write a message. This is not desirable when running
tests.
* guix/tests/git.scm (populate-git-repository): Make the 'tag' directive take
an additional argument, and pass it to the '-m' flag.
* tests/channels.scm ("channel-news, one entry"): Adjust accordingly.

+;;; Commentary:
+;;;
+;;; This module provides a generic package updater for packages hosted on Git
+;;; repositories.
+;;;
+;;; It tries to be smart about tag names, but if it is not automatically able
+;;; to parse the tag names correctly, users can set the `release-tag-prefix',
+;;; `release-tag-suffix' and `release-tag-version-delimiter' properties of the
+;;; package to make the updater parse the Git tag name correctly.
+;;;
+;;; Possible improvements:
+;;;
+;;; * More robust method for trying to guess the delimiter. Maybe look at the
+;;; previous version/tag combo to determine the delimiter.
+;;;
+;;; * Differentiate between "normal" versions, e.g., 1.2.3, and dates, e.g.,
+;;; 2021.12.31. Honor a `release-tag-date-scheme?' property?

I think that’s fine; this is all guesswork anyway, and there are always
cases where we’ll get it wrong. What’s useful though is tests to guard
against regressions in the heuristics.

Turns out that the failure in tests/channels.scm was a real bug:
‘channel-news-entry-commit’ was not resolving annotated tags correctly
(it would return the ID of the tag instead of the ID of the commit
pointed to by the tag). Fixed in
778c1fb4eabbb48c05f6c7555c89466d5249ebce.

Applied! I changed the second patch to preserve support for
non-annotated tags and to leave tests/channels.scm unchanged.
BTW, “git tag xyz” is not interactive AFAICS.
Thanks Sarah & Xinglu for this work! Let’s update our packages! :-)
