Previously, before replying to a /nar/* request, 'guix publish' would first
build up the whole nar into memory (as a consequence of
<http://bugs.gnu.org/21093>), which obviously doesn't scale.
* guix/scripts/publish.scm (render-nar): Return STORE-PATH instead of a
procedure that calls 'write-file'.
(sans-content-length): New procedure.
(http-write): For 'x-nix-archive', don't call '%http-write'. Instead, call
'write-file' right from here, using BODY as the file name.
* guix/scripts/publish.scm (%http-write): New variable.
(http-write): New procedure.
(concurrent-http-server): New variable.
(run-publish-server): Use it.
* guix/build/syscalls.scm (read-types): Add RETURN and VALUES parameters.
(define-c-struct): Add WRAP-FIELDS parameter and pass it to 'read-types'.
(sockaddr-in, sockaddr-in6): Add first argument that uses
'make-socket-address'.
(read-socket-address): Remove 'match' on the result of 'read-sockaddr-in'
and 'read-sockaddr-in6'.
* gnu/system.scm (<operating-system>)[kernel-arguments]: New field.
(operating-system-grub.cfg): Honor it.
(operating-system-parameters-file): Add 'kernel-arguments' to the parameters
file.
* guix/scripts/system.scm (previous-grub-entries)[system->grub-entry]: Read
the 'kernel-arguments' field of the parameters file, when available.
* gnu/system/vm.scm (system-qemu-image/shared-store-script):
Use (operating-system-kernel-arguments os) in '-append'.
* doc/guix.texi (operating-system Reference): Document it.
* guix/build-system/gnu.scm (gnu-build, gnu-cross-build): Accept #:build
keyword argument. Pass it to 'gnu-build' on the build side.
* guix/build/gnu-build-system.scm (configure): Accept #:build keyword
argument. Unless it is false, pass --build to configure.
* guix/scripts/substitute.scm (display-narinfo-data,
process-query, process-substitution): New procedures. Code moved from...
(guix-substitute): ... here. Use them.
* guix/scripts/substitute.scm (or*): New macro.
(%cache-url): Honor "untrusted-substitute-urls".
* guix/tests.scm (%test-substitute-urls): New variable.
(open-connection-for-tests): Use it.
* tests/derivations.scm ("derivation-prerequisites-to-build and substitutes",
"derivation-prerequisites-to-build and substitutes, non-substitutable
build", "derivation-prerequisites-to-build and substitutes, local build"):
Pass it to 'set-build-options'.
* tests/guix-daemon.sh: Likewise.
* tests/store.scm ("substitute query, alternating URLs"): New test.
("substitute query", "substitute", "substitute + build-things with output
path", "substitute, corrupt output hash", "substitute --fallback"): Pass
#:substitute-urls to 'set-build-options'.
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. Add the base32 of CACHE-URL as a sub-directory under
%NARINFO-CACHE-DIRECTORY. Update callers.
(cached-narinfo): Likewise. Call 'mkdir-p' on the dirname of the cache
file. Update callers.
(remove-expired-cached-narinfos): Add 'directory' parameter and use it
instead of %NARINFO-CACHE-DIRECTORY.
(narinfo-cache-directories): New procedure.
(maybe-remove-expired-cached-narinfo): Call 'remove-expired-cached-narinfos'
for each item returned by 'narinfo-cache-directories'.
* guix/scripts/substitute.scm (<cache>): Rename to...
(<cache-info>): ... this.
(open-cache): Rename to...
(download-cache-info): ... this. Return a <cache-info> or #f.
(open-cache*): Remove.
(cache-narinfo!): Take a URL instead of a <cache> as the first parameter.
(fetch-narinfos): Likewise. Call 'download-cache-info'. Remove use of
'force'.
(guix-substitute): Replace calls to 'open-cache*' with %CACHE-URL.
* guix/scripts/lint.scm (guix): Remove duplicated lines for using
'srfi-34' and 'srfi-35' modules. These lines were introduced twice by
commits b210b35 and 002c57c.
There were two issues:
1. Use of 'delete-duplicates', which is quadratic, was a serious problem for
closures with lots of propagated inputs, such as that of the 'hydra'
package (several minutes for 'guix build hydra -n'!).
2. The 'delete-duplicates' call essentially had no effect since duplicate
inputs typically had a different label and were thus kept. For
instance, (bag-transitive-inputs (package->bag inkscape)) would return
216 items whereas (delete-duplicates (map cdr THAT)) contains only 67
items.
The new implementation returns 67 items in this case. For 'hydra', we're
down from 42211 items to 361, and roughly 13s for 'guix build hydra'.
* guix/packages.scm (transitive-inputs): Rewrite as a breadth-first
traversal. Remove duplicate propagated inputs.
* tests/packages.scm ("package-transitive-inputs", "package->bag, propagated
inputs"): Adjust to use simple labels for propagated inputs, without "/".
("package-transitive-inputs, no duplicates"): New test.

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.

This fixes two problems:
1. Load errors would print an ugly backtrace.
2. When FILE was an absolute name, 'load' was passed an incorrect file
name.
* guix/scripts/environment.scm (options/resolve-packages): Use 'load*' instead
of 'load'.
* guix/scripts/environment.scm (package+propagated-inputs): Add 'output'
parameter. Use it in return value.
(options/resolve-packages): Use 'append-map' instead of 'map'. For 'load'
and 'expression', return all the outputs of the resulting package. For
'package', use 'specification->package+output' instead of
'specification->package'.
(guix-environment): Adjust uses of PACKAGES accordingly.
* doc/guix.texi (Invoking guix environment): Document it.
* tests/guix-environment.sh: Add test for --ad-hoc guile-bootstrap:out.
Before that, 'guix environment guile' (for instance) would define environment
variables that would refer to the "include" output of Bash, the "debug" output
of libgc, etc., even though these are not listed as inputs in the recipe of
'guile'.
* guix/gexp.scm (lower-inputs): Export.
* guix/scripts/environment.scm (evaluate-input-search-paths): Remove
'derivations' parameter; add 'search-paths'. Expect 'inputs' to be
a list of tuples. Adjust callers.
(create-environment): Remove 'derivations' parameter; add 'search-paths'.
(show-search-paths): Likewise.
(package+propagated-inputs): New procedure.
(packages->transitive-inputs, packages+propagated-inputs): Remove.
(build-inputs): Expect INPUTS to be a list of derivation tuples.
(guix-environment): Compute INPUTS using 'package+propagated-inputs',
'package->bag', and 'bag-transitive-inputs'. Move 'run-with-store' higher.
* tests/guix-environment.sh: Add test with FINDUTILS-BOOT0.
* guix/import/pypi.scm (python->package-name, maybe-inputs, compute-inputs,
guess-requirements): New procedures.
* guix/import/pypi.scm (guix-hash-url): Now takes a filename instead of an
URL as input.
* guix/import/pypi.scm (make-pypi-sexp): Now tries to generate the inputs
automagically.
* tests/pypi.scm: Update the test.
