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/scripts/substitute-binary.scm (filtered-port): Move to utils.scm.
(decompressed-port): Upon "none", return '() as the second value.
(guix-substitute-binary): Expect `decompressed-port' to return a list
of PIDs as its second value.
* guix/utils.scm (filtered-port): New procedure. Add case for when
INPUT is not `file-port?'.
* tests/utils.scm ("filtered-port, file", "filtered-port, non-file"):
New tests.
This should fix `substitute-binary --query' on Guile 2.0.5.
* guix/web.scm: New file.
* Makefile.am (MODULES): Add it.
* po/POTFILES.in: Add it.
* guix/gnu-maintenance.scm (http-fetch): Remove.
(%package-list-url): Turn into a URI.
(official-gnu-packages): Add #:text? #t to `http-fetch' call.
* guix/scripts/substitute-binary.scm (fetch): Remove `http' case, and
use `http-fetch' instead.
* guix/scripts/substitute-binary.scm (lookup-narinfo): Force CACHE when
passing it to `fetch-narinfo'.
(guix-substitute-binary): Delay calls to `open-cache'.
* guix/scripts/substitute-binary.scm (%narinfo-cache-directory,
%narinfo-ttl, %narinfo-negative-ttl): New variables.
(with-atomic-file-output, object->fields, read-narinfo,
write-narinfo, narinfo->string, string->narinfo, lookup-narinfo): New
procedures.
(fetch-narinfo): Adjust to use `read-narinfo'.
(guix-substitute-binary): Ensure the existence of
%NARINFO-CACHE-DIRECTORY. Use `lookup-narinfo' instead of
`fetch-narinfo'.
This allows build outputs to be transparently downloaded from
http://hydra.gnu.org, for example.
* config-daemon.ac: Check for `gzip', `bzip2', and `xz'.
* guix/config.scm.in (%gzip, %bzip2, %xz): New variable.
* guix/scripts/substitute-binary.scm (fetch): Return SIZE as a second value.
(<narinfo>): Change `url' to `uri'.
(make-narinfo): Rename to...
(narinfo-maker): ... this. Handle relative URLs.
(fetch-narinfo): Adjust accordingly.
(filtered-port, decompressed-port): New procedures.
(guix-substitute-binary): Implement the `--substitute' case.
* tests/store.scm ("substitute query"): Use (%store-prefix) instead
of (getenv "NIX_STORE_DIR").
("substitute"): New test.
* guix/scripts/substitute-binary.scm (guix-substitute-binary)["--query"]:
Emit blank lines only after the complete list of store paths has been
returned.
* guix/scripts/substitute-binary.scm: New file.
* Makefile.am (MODULES): Add it.
* nix/scripts/substitute-binary.in: New file.
* config-daemon.ac: Produce nix/scripts/substitute-binary.
* daemon.am (nodist_pkglibexec_SCRIPTS): Add
nix/scripts/substitute-binary.
* guix/store.scm (substitutable-path-info): Use the
`query-substitutable-path-infos' RPC.
* nix/nix-daemon/guix-daemon.cc (main): Honor `NIX_SUBSTITUTERS'.
* pre-inst-env.in: Set `NIX_SUBSTITUTERS'.
* test-env.in: Leave `NIX_SUBSTITUTERS' unchanged. Set
`GUIX_BINARY_SUBSTITUTE_URL, and create
$NIX_STATE_DIR/substituter-data.
Run `guix-daemon' within `./pre-inst-env'.
* tests/store.scm ("substitute query"): New test.
