* 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.
* guix/store.scm (add-to-store/cached): New variable.
Use it as the new `add-to-store'.
This reduces the number of RPCs when doing "guix-build gdb" from 5009
to 3053, and the execution time from 7s to 3.9s.
* guix/store.scm (gc-action): New enumerate type.
(read-long-long, read-string-list, write-store-path,
write-store-path-list, read-store-path-list): New procedures.
(write-arg): Add support for `store-path' and `store-path-list'.
(read-arg): Add support for `store-path-list'.
(define-operation): Add support for multiple-value returns.
(run-gc, live-paths, dead-paths, collect-garbage, delete-paths): New
procedures.
(%long-long-max): New macro.
* tests/store.scm: New file.
* Makefile.am (TESTS): Add it.
* configure.ac: Compute and substitute `guix_localstatedir'.
* m4/guix.m4: Substitute `guix_system'.
* guix/config.scm.in (%store-directory, %store-directory, %system): New
variables.
* guix/store.scm (%nix-state-dir): Remove.
(%default-socket-path): Use %STATE-DIRECTORY as the default.
(%store-prefix): Use %STORE-DIRECTORY as the default.
* guix/utils.scm (%current-system): Default to %SYSTEM.
* guix/store.scm (add-indirect-root): New operation.
* guix-build.in (show-help): Document `--root'.
(%options): Add `--root'.
(guix-build)[register-root]: New procedure. Call it when `--root' is
passed.
* distro/packages/base.scm (%guile-static, %guile-static-stripped): New
variables.
* distro/patches/guile-relocatable.patch: New file.
* Makefile.am (dist_patch_DATA): Add it.
We were already relying on the new version in `set-build-options', so
this patch fixes that.
* guix/store.scm (%protocol-version): Increase.
(open-connection)[reserve-space?]: New argument. Pass it to the
server when it's recent enough.
* guix/store.scm (valid-path?): New procedure.
* tests/builders.scm ("http-fetch", "gnu-build"): Use it.
* tests/derivations.scm ("add-to-store, flat", "add-to-store,
recursive", "derivation with no inputs", "build derivation with 1
source", "build derivation with coreutils",
"build-expression->derivation with expression returning #f"):
Likewise.
* guix/store.scm (set-build-options)[build-cores, use-substitutes?]: New
keyword parameters.
[send]: Change to expect a type, and use `write-arg'.
Send settings for BUILD-CORES and USE-SUBSTITUTES? when the server
supports it.
* guix/store.scm (current-build-output-port): New variable.
(process-stderr): Add docstring. Always return #f, except upon
%STDERR-LAST. Upon %STDERR-NEXT, write to
`current-build-output-port', not `current-error-port'.
(set-build-options): Loop until `process-stderr' returns true.
(define-operation): Likewise.
(build-derivations): Update docstring to mention that it's
synchronous.
* guix/store.scm (%store-prefix): New parameter.
(store-path?, derivation-path?): New procedures.
* guix/derivations.scm (write-derivation): Pass SOURCES through
`object->string'.
(compressed-hash, store-path, output-path, derivation): New
procedures.
* tests/derivations.scm (%store): New global variable.
("derivation with no inputs"): New test.
* guix/store.scm (&nix-error, &nix-protocol-error): New SRFI-35
condition types.
(process-stderr): Raise an error condition upon protocol errors
instead of returning to the caller. This allows the connection to be
reused for further interactions.
