* guix/build-system/gnu.scm (inputs-search-paths): New procedure.
(standard-search-paths): Use it.
(expand-inputs): New procedure.
(standard-inputs): Use it.
(standard-cross-packages, standard-cross-inputs,
standard-cross-search-paths, gnu-cross-build): New procedures.
(gnu-build-system): Set `cross-build' field to `gnu-cross-build'.
* gnu/packages/cross-base.scm: Export `cross-gcc', `cross-binutils', and
`cross-libc'.
* guix/build/gnu-cross-build.scm: New file.
* Makefile.am (MODULES): Add it.
* gnu/packages/patches/gcc-cross-environment-variables.patch: Add two
hunks, most notably one that changes GCC to honor LIBRARY_PATH_ENV
when cross-compiling.
* guix/packages.scm (expand-input): New procedure, moved out of...
(package-derivation): ... here. Adjust accordingly.
(package-cross-derivation): Add `cross-system' and `system'
parameters.
* gnu/packages/autotools.scm (autoconf-wrapper): Wrap `configure' files
regardless of the exit code of `autoconf'. Triggered by Automake's
`t/am-prog-cc-stdc.sh'.
(automake): Update to 1.13.2.
* guix/scripts/package.scm (guix-package)[ensure-default-profile]: Check
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.
* guix/scripts/substitute-binary.scm (fetch): Add `buffered?'
parameter. Pass it to `http-fetch'; honor it for `file' URIs.
(guix-substitute-binary): Call `fetch' with #:buffered? #f for port RAW.
* tests/utils.scm ("filtered-port, file"): Open FILE as unbuffered.
* guix/scripts/substitute-binary.scm (%regexp-exec-mutex): New variable.
(string->uri): New procedure.
(fields->alist): Wrap `regexp-exec' call in `with-mutex'.
* guix/ftp-client.scm (ftp-open): Let exceptions through.
* guix/scripts/package.scm (waiting): Wrap EXP in a `dynamic-wind', so
the line is always cleared.
* guix/scripts/hash.scm (guix-hash)[eof->null]: New procedure.
Use it to convert the EOF object to the empty bytevector.
* tests/guix-hash.sh: New file.
* Makefile.am (SH_TESTS): Add it.
* guix/scripts/refresh.scm (%options): Add `--key-server' and `--gpg'.
(show-help): Update accordingly.
(update-package): New procedure, formerly in `guix-refresh'.
(guix-refresh): Use it. Parameterize `%openpgp-key-server' and
`%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.
