Custom channel is making guix pull fail

Custom channel is making guix pull fail

Hi,

Could you help me find out what I'm doing wrong here, please? :)

I have a custom channel 
(https://codeberg.org/luis-felipe/guix-channel-x) that had been working 
fine for a very long time, but now running "guix pull" fails with the 
following error:

#+begin_quote

guix pull: error: build of 
`/gnu/store/99w71gp2rxzb7g1ij62qag769bryxwzi-profile.drv' failed
#+end_quote

And the referenced build log reads as follows:

#+begin_quote
(repl-version 0 1 1)
guix repl: warning: '%gnu-build-system-modules' is deprecated,

WARNING: (guix build guile-easy-build-system):

(exception match-error (value "match") (value "no matching pattern") 
(value ()))
#+end_quote

My "channels.scm" configuration looks like this:

#+begin_src scheme
;;; Guix channels definitions.
;;; Location: ~/.config/guix/channels.scm

(use-modules (guix ci))

(list
  (channel
   (name 'luflac-x)
   (url "https://codeberg.org/luis-felipe/guix-channel-x.git")
   (branch "trunk")
   (introduction
    (make-channel-introduction
     "53e5e8864d04efb8d7315719575718665c68c792"
     (openpgp-fingerprint
      "0910 827A 2E06 1E61 6C06  AC3D 0AB0 D067 012F 08C3"))))

  (channel-with-substitutes-available
   %default-guix-channel
"https://ci.guix.gnu.org"))
#+end_src

Wanting to debug the problem using a local copy of my channel, I changed 
my channel's record in "channels.scm" as follows:

#+begin_src scheme
(use-modules (guix ci))

(list
  #;
  (channel
   (name 'luflac-x)
   (url "https://codeberg.org/luis-felipe/guix-channel-x.git")
   (branch "trunk")
   (introduction
    (make-channel-introduction
     "53e5e8864d04efb8d7315719575718665c68c792"
     (openpgp-fingerprint
      "0910 827A 2E06 1E61 6C06  AC3D 0AB0 D067 012F 08C3"))))
  ;; NOTE: Use the following definition to debug the channel locally.
  (channel
   (name 'luflac-x)
   (url (string-append (getenv "HOME") "/guix-channel-x"))
   (branch "debug")
   (introduction
    (make-channel-introduction
     "53e5e8864d04efb8d7315719575718665c68c792"
     (openpgp-fingerprint
      "0910 827A 2E06 1E61 6C06  AC3D 0AB0 D067 012F 08C3"))))

  (channel-with-substitutes-available
   %default-guix-channel
   "https://ci.guix.gnu.org"))
#+end_src

But then "guix pull" fails with the following error:

#+begin_quote
Updating channel 'luflac-x' from Git repository at 
'/home/yo/guix-channel-x'...
guix pull: error: Git error: cannot locate remote-tracking branch 
'origin/debug'
#+end_quote

I don't understand why git is looking for a remote-tracking branch in 
"origin". The "debug" branch is available locally only. And even if I 
push it to origin, I get the same error when running "guix pull" again.

Also, if I change the branch to "trunk", I get the following error:

#+begin_quote
Updating channel 'luflac-x' from Git repository at 
'/home/yo/guix-channel-x'...
guix pull: error: Git error: cannot locate remote-tracking branch 
'origin/keyring'
#+end_quote

Even though the "keyring" branch exists both locally and remotely (in 
"origin")...

Finally, and for what it's worth, I can import all modules in the 
channel from a Guile REPL without errors.

Thanks in advance,

Hola Luis,

Regarding the issue I can't help but to use a local channel it has to start with file:// so:

(url (string-append "file://" (getenv "HOME") "/guix-channel-x"))

should do it

Before anything else, did you change anything in your private channel
before the breakage occurred?

Alternatively, you could see how =guix pull= reacts to the = --commit =
option.  It is possible that something got broken in master branch, yet
again.

Actually, I had already tried that, but I got the same error. And I just 
tried again to be sure, and yeah:

#+begin_quote
guix pull
Updating channel 'luflac-x' from Git repository at 
'file:///home/yo/guix-channel-x'...
guix pull: error: Git error: cannot locate remote-tracking branch 
'origin/debug'
#+end_quote

Thanks for checking, Moisés.

Maybe something was renamed in master that broke the package definition
of luflac-x in your channel?

Sorry I cannot be more helpful.

Kind regards

Yeah, thanks, that seems to be the case. Actually, "luflac-x" is the 
name of the channel, and its derivation fails to build. Apparently, the 
problem is in a custom guile build system I defined in the channel. If I 
remove the build system and the packages that depend on it, the channel 
builds again. So I have to inspect that.

Unfortunately, though, the errors related to using a local URI as the 
URL of the channel still remain, even if I remove the custom build 
system and the packages that depend on it.

> Sorry I cannot be more helpful.

No problem, thanks for taking a look :)

Problem solved. And for the sake of closure:

Since I couldn't find the exact problem using guix c6ff1d6, I decided to 
exclude my channel and upgrade my system (now guix 0feeac3). This time, 
importing my build system module in a guix repl consistently reported a 
similar problem to the one displayed when performing "guix pull" in my 
initial message:

#+begin_src shell
❯ guix repl -L .
scheme@(guix-user)> (use-modules (guix build guile-easy-build-system))
While compiling expression:
Throw to key `match-error' with args `("match" "no matching pattern" ())'.
#+end_src

Great, because that way I could start debugging that module locally.

The problem was in the definition of the standard phases of my 
"guile-easy" build system:

#+begin_src scheme
(define %standard-phases
   (modify-phases gbs:%standard-phases
     (delete 'install-documentation)
     (delete 'compress-documentation)
     (delete 'delete-info-dir-file)
     (delete 'validate-documentation-location)

     (add-after 'set-paths 'add-output-to-guile-load-paths
       add-output-to-guile-load-paths)
     (add-after 'build 'check check)
     ;; These two below were responsible for the "match-error":
     (add-after 'install 'install-scripts install-scripts)
     (add-after 'install 'install-info-manual install-info-manual)))
#+end_src

The last two phases, "install-scripts" and "install-info-manual", were 
added after the "install" phase, but there is no such phase: The phases 
of my "guile-easy" build system inherit from "guile"'s build system 
phases (referred to as "gbs:%standard-phases" in the previous code), 
which in turn inherit from the "gnu"'s build system phases, but the 
guile build system explicitly deletes the "install" phase (among other 
phases).

Apparently, in this version of Guix referring to non-existing phases 
breaks the code. This wasn't the case in Guix c81ed09, for example, 
where I can build packages that use the guile-easy build system just fine.

So, the solution was to change the standard phases definition so that 
the faulty phases refer to phases that actually exist:

#+begin_src scheme
(define %standard-phases
   (modify-phases gbs:%standard-phases
     (delete 'install-documentation)
     (delete 'compress-documentation)
     (delete 'delete-info-dir-file)
     (delete 'validate-documentation-location)

     (add-after 'set-paths 'add-output-to-guile-load-paths
       add-output-to-guile-load-paths)
     (add-after 'build 'check check)
     (add-after 'check 'install-scripts install-scripts)
     (add-after 'check 'install-info-manual install-info-manual)))
#+end_src

On a side note, building a package that uses my faulty build system in 
my new Guix, a useful backtrace is printed, but it seems to me that 
there might be a defect in the Guix code there:

#+begin_src shell
❯ guix build -L . guile-documenta
guix build: warning: failed to load '(guix build guile-easy-build-system)':

It seems to me that "guix/ui.scm" tries to report more useful 
information about the problem loading "guile-easy-build-system" but then 
"display-error" complains about not getting the right number of 
arguments (?).

Anyways, my channel is working again, problem solved (or so it seems :)).
