2016-03-16substitute: Honor client-provided empty URL list.Ludovic Courtès
Before that, 'guix build --substitute-urls=""' would lead to using the daemon's own URL list instead of the empty list. The 'or*' hack, which is to blame, had become unnecessary since commit fb4bf72be3fbc23bca35ba4b842b7e1517ef0e3a.

Return an open port in addition to a <cache-info>. * guix/scripts/substitute.scm (http-multiple-get): Add #:port parameter and honor it. (fetch-narinfos)[do-fetch]: Add 'port' parameter. Adjust to new 'download-cache-info' and 'do-fetch' signatures.

Use 'open-connection-for-uri' instead of 'open-socket-for-uri'. Call 'setvbuf' only when PORT matches 'file-port?'. (http-multiple-get): Likewise. Change 'base-url' parameter to 'base-uri'. (fetch-narinfos)[do-fetch]: Add 'https' case alongside 'http'. Pass URI instead of URL to 'http-multiple-get'. * doc/guix.texi (Requirements): Move GnuTLS one level higher and mention HTTPS substitutes. (Substitutes): Mention HTTPS and recommend it. Explain why servers are not authenticated. Add "On Trusting Binaries" subsection.
2016-03-09substitute: Error out on unsupported URL schemes.Ludovic Courtès
Reported in <http://bugs.gnu.org/22937> by Chris Marusich <cmmarusich@gmail.com>. * guix/scripts/substitute.scm (fetch): Add 'else' case and call 'leave'.

2015-10-28substitute: 'http-multiple-get' follows 'fold' style.Ludovic Courtès
* guix/scripts/substitute.scm (http-multiple-get): Add 'seed' parameter. Call PROC in 'fold' style. (fetch-narinfos)[handle-narinfo-response]: Adjust accordingly. Update 'http-multiple-get' call accordingly.

2015-09-04publish: Gracefully handle the lack of a deriver.Ludovic Courtès
* guix/scripts/publish.scm (narinfo-string): Catch 'system-error' around 'load-derivation' call; return BASE-INFO upon ENOENT. This allows us to return the narinfo even if DERIVER is missing. Before that, the exception would be uncaught, leading to 500 Internal Error on the client side.

* guix/scripts/substitute.scm (display-narinfo-data, process-query, process-substitution): New procedures. Code moved from... (guix-substitute): ... here. Use them.

This ensures that switching between different substitute servers doesn't lead to a polluted narinfo cache. * guix/scripts/substitute.scm (narinfo-cache-file): Add 'cache-url' parameter.

2015-07-13substitute: Remove unneeded conditionals.Ludovic Courtès
* guix/scripts/substitute.scm (guix-substitute): Remove unneeded (if cache ...) forms since CACHE is always true (it's a promise.)
2015-07-07substitute: Avoid infinite loop when updating the substitute list.Andy Patterson
Reported at <http://lists.gnu.org/archive/html/guix-devel/2015-07/msg00119.html>. * guix/scripts/substitute.scm (http-multiple-get): When RESP has "Connection: close", consume HEAD anyway; always call PROC to read from BODY. Co-authored-by: Ludovic Courtès <ludo@gnu.org>

* guix/scripts/authenticate.scm (%default-port-conversion-strategy): Remove. * guix/scripts/substitute.scm (fetch): Remove 2.0.5 special cases. * guix/serialization.scm (write-file): Remove 'scandir' workaround. * guix/ui.scm (command-files): Likewise.
2015-05-06download: Work around Guile small-receive-buffer bug.Ludovic Courtès
Previously, code using directly (guix build download) was still affected by <http://bugs.gnu.org/15368>. This includes source derivations, the 'guix download' command, and (guix gnu-maintenance). 'guix substitute' was unaffected since it used (guix http-client), which already had the fix. * guix/http-client.scm (open-socket-for-uri): Remove. (http-fetch): Remove #:buffered? argument to 'open-socket-for-uri'; use 'setvbuf' instead. * guix/scripts/substitute.scm (fetch): Likewise. * guix/build/download.scm (open-socket-for-uri): New procedure, taken from guix/http-client.scm, but without the #:buffered? parameter.

2015-03-25substitute: Rename cache directory from "substitute-binary" to "substitute".Ludovic Courtès
