* guix/build/download.scm (http-fetch)[post-2.0.7?]: Use
'string->number' and numeric comparison. This fixes version
comparison with "2.0.10" and subsequent 2.0 releases.
Fixes <http://bugs.gnu.org/16703>.
Reported by Raimon Grau <raimonster@gmail.com>.
* guix/build/download.scm (http-fetch)[headers]: New variable.
Pass it as #:headers or #:extra-headers to 'http-get' and
'http-get*'.
* guix/scripts/substitute-binary.scm (decompressed-port): Improve docstring.
(progress-report-port): New procedure.
(guix-substitute-binary)["--substitute"]: Use it to report progress.
* guix/build/download.scm: Export `progress-proc' and `uri-abbreviation'.
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).
* guix/build/download.scm: Autoload (gnutls).
(tls-wrap): New procedure.
(open-connection-for-uri): Add support for `https'. Wrap the socket
with `tls-wrap' in that case.
(url-fetch): Add `https'.
* guix/download.scm (gnutls-derivation): New procedure.
(url-fetch)[need-gnutls?]: New variable.
Call `gnutls-derivation' when NEED-GNUTLS? is true, and add its output
to the `GUILE_LOAD_PATH' env. var. in that case.
* guix/build/download.scm (uri-abbreviation): New procedure.
(ftp-fetch, http-fetch): Use it instead of `uri->string' when calling
`progress-proc'. Reported by Andreas Enge.
* guix/build/download.scm (http-fetch): Rename `bv' to `bv-or-port'.
Use `http-get*' followed by `dump-port' when the former is available,
and pass a progress procedure to `dump-port'.
* guix/build/download.scm (progress-proc): New procedure.
(ftp-fetch): Call `ftp-size' on URI. Use `progress-proc', and pass
the result to `dump-port', along with #:buffer-size.
* guix/build/download.scm (open-connection-for-uri): Delete addrinfos
with the same address. Always open SOCK_STREAM/IPPROTO_IP sockets.
Fix the error handler's condition to determine what to do.
