contains (use-modules ...) clauses, and can be achieved differently
anyway.
* guix/build/utils.scm (set-path-environment-variable): When VALUE is

the owner of %PROFILE-DIRECTORY. Report an error when the owner is
not the current user. Add `rtfm' procedure.
* doc/guix.texi (Invoking guix package): Mention the ownership test.
This fixes a bug whereby `read-response' would read more than just the
response, with the extra data going into the port's buffer; the
"bzip2 -dc" process spawned by `filtered-port' would not see the those
buffered data, which are definitely lost, and would bail out with
"bzip2: (stdin) is not a bzip2 file."
* guix/utils.scm (filtered-port): Document that INPUT must be
unbuffered.
* guix/web.scm (http-fetch): Add `buffered?' parameter. Call
`open-socket-for-uri' explicitly, and call `setvbuf' when BUFFERED? is
false. Pass the port to `http-get'. Close it upon 301/302.

parameter. Pass it to `http-fetch'; honor it for `file' URIs.

`%gpg-command'.
* guix/gnupg.scm (%gpg-command): Turn into a SRFI-39 parameter.
(%openpgp-key-server): Likewise. Default to pgp.mit.edu, as
keys.gnupg.net is unreliable.
Update users.
* guix/ui.scm (show-guix-usage): Mention `guix --help'.
Suggested by Mark H. Weaver.
(run-guix-command): Invoke it when a command is not found.
(guix-main): Adjust accordingly.
* guix/scripts/package.scm (guix-package)[process-actions](package->tuple):
Put the output path in the tuple, not the derivation path.
* tests/guix-package.sh: Add test.
Before this, something like "guix package -i glibc" could fail because
glibc lists linux-libre-headers as a propagated input (which would be
added as a dependency in the manifest) but the linux-libre-headers
output could be unavailable, leading to an error like this:
path `/nix/store/4v2bk8sx5cm166gks3fi3q7d9zchibnk-linux-libre-headers-3.3.8' is not valid
This patch adds such dependencies as inputs of the profile derivation.
* guix/scripts/package.scm (profile-derivation): Accept package objects
in the `deps' field of an element of PACKAGES. Convert them to their
output path for BUILDER, and add them to the inputs of the
`build-expression->derivation' call.
(input->name+path): When INPUT doesn't contain a package object,
return it as is.
(guix-package)[process-actions](canonicalize-deps): Expect DEPS to
contain package objects, and leave them as is.
* guix/scripts/refresh.scm (guix-refresh): When updating a source file,
gracefully handle the case where TARBALL is #f.
Reported by Nikita Karetnikov <nikita@karetnikov.org>.
* guix/ui.scm (run-guix-command): Can `resolve-interface' errors and
report them with `leave'. Parameterize `program-name' from here.
(guix-main): Remove parameterization of `program-name'.
This would manifest when downloading a large file such as the Bazaar
tarball, leading to an "Error in the pull function" GnuTLS exception.
* guix/build/download.scm (add-weak-reference): New procedure.
(tls-wrap): Add (add-weak-reference record port).
