Just try this:

``` bash
$ file `guix build fbreader --with-latest=fbreader -S`
/gnu/store/rdqkmjpiig9gddzsxj4mdyw8lvn944xg-FBReader: HTML document, UTF-8 Unicode text, with very long lines

```

If a package is a git source package, after use "with-latest" option, it's url
will become to it's source. and build will fail.

This patch just fix this.

But i think this patch not good, maybe need a new patch(use latest version
not latest commit). But i'm not familiar with this part.

I see. However, I am not convinced your example is correct, because
for instance,

Toggle snippet (5 lines)
$ file $(guix build r-soupx -S)
/gnu/store/1z0j6i4a9xwwd8d3955m7vq3f1x4p3aq-r-soupx-0.3.1-1.a3354be-checkout:
directory

What you are seeing is: Git upstream source is modified by Guix (for
instance, patches are applied or files are removed; in the field
'origin') and "guix build -S" returns what Guix actually builds, not
what upstream provides. Therefore, in this case, the modified source
is returned as compressed archive. However, when using the
transformation 'with-latest', in this case, "guix build -S
--with-latest" returns what upstream provides, thus a directory (or
something else as a file).

Maybe I miss something, but from me, the inconsistency comes from the
behavior of "guix build -S", not about the behaviour of 'with-latest'
transformation. And I also miss why the build would fail.


Cheers,
simon

I looked source again, just because of "upstream-source-compiler" don't support
git source package, all will become to use url-fetch.

See (guix upstream) module:

``` scheme
(define-gexp-compiler (upstream-source-compiler (source <upstream-source>)
system target)
"Download SOURCE from its first URL and lower it as a fixed-output
derivation that would fetch it."
(mlet* %store-monad ((url -> (first (upstream-source-urls source)))
(signature
-> (and=> (upstream-source-signature-urls source)
first))
(tarball ((store-lift download-tarball) url signature)))
(unless tarball
(raise (formatted-message (G_ "failed to fetch source from '~a'")
url)))

;; Instead of returning TARBALL, return a fixed-output derivation that
;; would be able to re-download it. In practice, since TARBALL is already
;; in the store, no extra download will happen, but having the derivation
;; in store improves provenance tracking.
(let ((hash (call-with-input-file tarball port-sha256)))
(url-fetch url 'sha256 hash (store-path-package-name tarball)
#:system system))))

```

I'm have no idea how to change it, so i just check if package is
git-source, use "git-checkout" instead of "upstream-source".

I am sorry if I misread you. What are you trying to solve?
