* gnu/build/vm.scm (estimated-partition-size): New procedure.
* gnu/system/vm.scm (expression->derivation-in-linux-vm):
Change #:disk-image-size default to 'guess.
[builder]: When DISK-IMAGE-SIZE is 'guess, use
'estimated-partition-size' and compute and estimate of the image size.
(qemu-image): Likewise.
* guix/build/store-copy.scm (file-size, closure-size): New procedures.
* guix/scripts/system.scm (%default-options): Change 'image-size' to
'guess.

Fixes <http://bugs.gnu.org/27262>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/scripts/package.scm (transaction-upgrade-entry): Check if ENTRY
matches 'manifest-transaction-removal-candidate?' and return TRANSACTION
if it does.
(process-actions): Move 'options->removable' from step 2 to step 1.
* guix/profiles.scm (manifest-transaction-removal-candidate?): New
procedure.
* tests/profiles.scm ("manifest-transaction-removal-candidate?"): New
test.
Fixes <http://bugs.gnu.org/27261>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/scripts/package.scm (transaction-upgrade-entry): Add call to
'warning' when NAME cannot be found in the package set.
* guix/scripts/refresh.scm (check-for-package-update): Use
'version-compare' instead of 'version>?'. When WARN? is true, print
something for the '=' and '<' cases.
* guix/store.scm (%default-guix-port): New variable.
(connect-to-daemon)[connect]: Use it when (uri-port uri) is #f.
* doc/guix.texi (The Store): Mention the default port number.
Reported by Efraim Flashner.
This is a followup to a654dc4bcf.
* guix/profiles.scm (profile-derivation): Add #:allow-collisions? and
honor it.
* guix/scripts/environment.scm (inputs->profile-derivation): Pass
#:allow-collisions? #f to 'profile-derivation'.
* tests/guix-environment.sh: Test "guix environment guix".
* guix/profiles.scm (<manifest-entry>)[parent]: New field.
(package->manifest-entry): Add #:parent parameter. Fill out the
'parent' field of <manifest-entry>; pass #:parent in recursive calls.
* guix/profiles.scm (sexp->manifest)[sexp->manifest-entry]: New
procedure. Use it for version 3.

("read-manifest")[entry->sexp]: Add 'manifest-entry-parent' to the
result.

(manifest-inputs)[entry->gexp]: New procedure.
Adjust to 'dependencies' being a list of <manifest-entry>.
* tests/profiles.scm ("packages->manifest, propagated inputs")
("read-manifest"): New fields.
For a command like:
guix build python2-numpy -n
this reduces the number of 'write' syscalls from 9.5K to 2.0K.
* guix/store.scm (<nix-server>)[buffer, flush]: New fields.
(open-connection): Adjust accordingly. Call 'buffering-output-port' to
compute the two new fields.
(write-buffered-output, buffering-output-port): New procedures.
(operation): Write to (nix-server-output-port server). Call
'write-buffered-output'.
Fixes a regression introduced in
d27cc3bfaa.
Reported by Ricardo Wurmus <rekado@elephly.net>.
* guix/discovery.scm (scheme-files): Catch 'scandir*' system errors.
Return '() and optionally raise a warning upon 'system-error'.

(show-rpc-profile, record-operation): New procedures.
(operation): Add call to 'record-operation'.
* guix/ui.scm (run-guix-command): Wrap COMMAND-MAIN in 'dynamic-wind'.
Run EXIT-HOOK.
On a command like:
guix environment --ad-hoc coreutils -- true
this reduces the number of 'stat' calls from 14.1K to 9.7K on my
setup (previously each getdents(2) call would be followed by one stat(2)
call per entry).
* guix/discovery.scm (scheme-files): Rewrite using 'scandir*'.
* guix/scripts/package.scm (find-packages-by-description): Rewrite to
compute a score based on the number of regexps matched and the number of
matches for each regexp. Sort according to this score and return it as
a second value.
(process-query) <'search>: Capture the two return values of
'find-packages-by-description'. Pass #:extra-fields to
'package->recutils'.
* doc/guix.texi (Invoking guix package): Mention relevance, give an
example.
This avoids the open/fstat/close syscalls upon a cache hit that we had
with the previous idiom:
(call-with-input-file file read-derivation)
where caching happened in 'read-derivation' itself.
* guix/derivations.scm (%read-derivation): Rename to...
(read-derivation): ... this.
(read-derivation-from-file): New procedure.
(derivation-prerequisites, substitution-oracle)
(derivation-prerequisites-to-build):

'read-derivation-from-file' instead of (call-with-input-file …
read-derivation).

* guix/scripts/build.scm (log-url, options->things-to-build): Likewise.
* guix/scripts/graph.scm (file->derivation): Remove.

* guix/scripts/publish.scm (load-derivation): Remove.
(narinfo-string): Use 'read-derivation-from-file'.
The `install' phase of the emacs-build-system contained default arguments
duplicated from the host side `emacs-build' procedure. This change factorizes
them so that:
1. They are not duplicated.
2. They can be reused and extended easily when defining emacs packages.
* guix/build/emacs-build-system.scm (%default-include, %default-exclude): New
variables.
(install): Use %default-include and %default-exclude as default arguments.
* guix/build-system/emacs.scm: Use and re-export %default-include,
%default-exclude from (guix build emacs-build-system).
(emacs-build): Use %default-include and %default-exclude as default arguments.

Fixes <http://bugs.gnu.org/26972>.
* guix/ssh.scm (store-import-channel)[import]: Add 'consume-input'
procedure. Wrap body in 'catch' and 'guard'. Use 'open-remote-pipe'
with OPEN_BOTH instead of 'open-remote-output-pipe'.
(send-files): After the 'channel-send-eof' call, do (read port).
Interpret the result sexp and raise an error condition if needed.
* guix/derivations.scm (derivation-prerequisites-to-build): Rename
#:substitutable? to #:substitutable-info.
[derivation-substitutable?]: Rename to...
[derivation-substitutable-info]: ... this. Return a list of <substitutable>.
Second return value is now a list of <substitutable> instead of a list
of strings.
* guix/ui.scm (show-what-to-build)[substitutable?]: Rename to...
[substitutable-info]: ... this.
Adjust to new 'derivation-prerequisites-to-build' return value type.
* tests/derivations.scm ("derivation-prerequisites-to-build and
substitutes"): Adjust.
("derivation-prerequisites-to-build and substitutes, local build"):
Likewise.
* guix/derivations.scm (substitution-oracle): Use
'substitution-path-info' instead of 'substitution-paths'. Turn SUBST
into a vhash from path to <substitutable>. Change the returned
procedure to provide a <substitutable> instead of a Boolean.
* tests/derivations.scm ("substitution-oracle and #:substitute? #f"):
Mock 'substitutable-path-info' instead of 'substitutable-paths'.
