* guix/store.scm (open-connection): Remove misleading 'setsockopt' call,
erroneously introduced in df1fab58. This would actually shrink the
receive buffer from 124 KiB to 12 KiB, though it had little impact on
performance.
This allows progress reports emitted by 'substitute-binary' to be
correctly displayed.
* guix/store.scm (%newlines): New variable.
(process-stderr) <%stderr-next>: Flush (current-build-output-port)
when S contains one of %NEWLINES.
* guix/store.scm (topologically-sorted): New procedure.
* tests/store.scm ("topologically-sorted, one item",
"topologically-sorted, several items", "topologically-sorted, more
difficult"): New tests.
* guix/store.scm (add-text-to-store): Make 'references' optional.
* tests/store.scm ("dead-paths", "references"): Use 'add-text-to-store'
with no optional argument.
* doc/guix.texi (The Store): Adjust accordingly.
* guix/store.scm: Remove unneeded (ice-9 rdelim) import. In Guile 2.0.9
that module exports `read-string', which conflicts with that of (guix
serialization).
* 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.
* guix/store.scm (write-contents)[call-with-binary-input-file]: New
procedure.
Use `sendfile' instead of `dump' when available. Add `size'
parameter.
(write-file): Update caller.
* guix/store.scm (&nix-connection-error): New condition type.
(open-connection): Translate `system-error' during the `connect' call
into `&nix-connection-error'.
* guix/ui.scm (call-with-error-handling): Add case for `nix-connection-error?'.
* guix/scripts/package.scm (guix-package): Move `open-connection' call
within `with-error-handling'.
* guix/scripts/pull.scm (guix-pull): Likewise.
* guix/scripts/download.scm (guix-download): Move body within
`with-error-handling'.
* guix/store.scm (%protocol-version): Bump.
(operation-id): Comment out `query-substitutable-path-info'.
Rename `query-valid-paths' to `query-all-valid-paths'. Add
`query-path-from-hash-part', `query-substitutable-path-infos',
`query-valid-paths', and `query-substitutable-paths'.
(set-build-options): Add `binary-caches' keyword parameter. When
using a server >= 1.12, send the list of binary caches.
(query-path-hash): Use the `store-path' type, for clarity.
* guix/store.scm (open-connection): Call `make-hash-table' with 100.
(add-text-to-store): Move TEXT first in ARGS, for better `hash'
results.
(add-to-store): Likewise, move ST first.
* guix/store.scm (add-to-store): Remove the `fixed?' parameter from the
public interface.
* gnu/packages/bootstrap.scm, guix-download.in, guix/derivations.scm,
guix/packages.scm, tests/derivations.scm: Update all callers
accordingly.
* guix/store.scm (operation): New macro.
(define-operation): Define in terms of `operation'.
(add-text-to-store): Define using `operation', and remove now
unnecessary `set!'.
(add-to-store): Likewise.
(add-text-to-store/cached, add-to-store/cached): Remove.
* guix/store.scm (write-string): Optimize to write the length, contents,
and padding all at once. This yields a 2% improvement on the
execution time of "guix-build gdb".
* guix/store.scm (<nix-server>)[atts-cache]: New field.
(add-text-to-store/cached): New procedure. Use it as a wrapper around
`add-text-to-store'.
When running "guix-build gdb", this reduces the number of RPCs from
3048 to 289, and execution time from 4.7s to 2.6s.
* guix/store.scm (<nix-server>)[ats-cache]: New field.
(open-connection): Update accordingly.
(add-to-store/cached): Use (nix-server-add-to-store-cache SERVER)
instead of a weak hash table.
