Previously 'process-stderr' would always pass a bytevector of MAX-LEN to
then daemon in the %stderr-read case (i.e., 'import-paths'), instead of
LEN (where LEN <= MAX-LEN).
In practice the extra bytes didn't cause a protocol violation or
anything because they happen at the end of the stream, which typically
contains the canonical sexp of the signature, and the extra zeros were
just ignored.
* guix/serialization.scm (write-bytevector): Add optional 'l' parameter
and honor it.
* guix/store.scm (process-stderr): Pass LEN to 'write-bytevector'.
When current-processor-count is used without (ice-9 threads) being used, Guile
complains with the following warning:
Import (ice-9 threads) to have access to `current-processor-count'.
* guix/store.scm: Use (ice-9 threads).
Until now the cache was always empty because 'for-each' was passed ITEMS
as its second argument, and ITEMS was the empty list at that point.
* guix/store.scm (references/substitutes): Add 'requested' variable.
Use it as second argument of 'for-each' in base case.
* 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.
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'.
* guix/store.scm (%rpc-calls): New variable.
(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.
* guix/monads.scm (%templates, %template-instances): New variables.
(register-template!, register-template-instance!): New procedures.
(template-directory, define-template): New macro.
(foldm, sequence, anym): Define using 'define-template'. Avoid replace
ellipses with dots.
(mapm): Likewise, but do not use 'foldm'.
* guix/store.scm: Add 'template-directory' invocation.
This allows 'guix' commands to talk to a remote store over SSH.
* guix/store.scm (connect-to-daemon)[connect]: Call 'resolve-interface'
for unknown URI schemes.
* guix/store/ssh.scm: New file.
* Makefile.am (MODULES): Add it.
* doc/guix.texi (The Store): Document it. Mark remote access as
experimental.
* guix/serialization.scm (write-bytevector): New procedure.
(write-string): Rewrite in terms of 'write-bytevector'.
* guix/store.scm (write-arg): Add 'bytevector' case.
(add-data-to-store): New procedure, from former 'add-text-to-store'.
(add-text-to-store): Rewrite in terms of 'add-data-to-store'.
* tests/store.scm ("add-data-to-store"): New test.
Fixes <http://bugs.gnu.org/20217>.
* nix/libstore/worker-protocol.hh (PROTOCOL_VERSION): Bump to 0x161.
* nix/nix-daemon/nix-daemon.cc (performOp): "build-max-jobs",
"build-max-silent-time", and "build-cores" are no longer read upfront;
instead, read them from the key/value list at the end.
* nix/nix-daemon/guix-daemon.cc (main): Explicitly set
'settings.maxBuildJobs'.
* guix/store.scm (%protocol-version): Bump to #x161.
(set-build-options): #:max-build-jobs, #:max-silent-time, and
#:build-cores now default to #f. Adjust handshake to new protocol.
* tests/store.scm ("build-cores"): New test.
* tests/guix-daemon.sh: Add test for default "build-cores" value.
* guix/store.scm (open-connection): Guard body against 'nar-error?' and
re-raise as '&nix-connection-error'.
* tests/store.scm ("connection handshake error"): New test.
* guix/store.scm (write-arg): Remove 'file' case.
(true): New procedure.
(add-to-store): Add #:select? parameter and honor it. Use hand-coded
stub instead of 'operation'.
(interned-file): Add #:select? parameter and honor it.
* doc/guix.texi (The Store Monad): Adjust 'interned-file' documentation
accordingly.
* guix/store.scm (set-build-options): Add #:terminal-columns parameter
and honor it.
* guix/scripts/substitute.scm (client-terminal-columns): New procedure.
(guix-substitute): Use it to parameterize 'current-terminal-columns'.
This allows GuixSD to default to the right list of URLs, with
mirror.hydra.gnu.org coming first.
Reported by Chris Marusich <cmmarusich@gmail.com>.
* guix/store.scm (%default-substitute-urls): Prepend
"mirror.hydra.gnu.org."
Before that, 'references/substitutes' would assume that
'substitutable-path-info' would return things in the same order as its
arguments, which is not the case. Thus, it would sometimes provide
incorrect reference information, occasionally leading to infinite
loop (because dependency information would denote cycles.)
Fixes <http://bugs.gnu.org/22914>.
Reported by Eric Bavier <ericbavier@openmailbox.org>.
* guix/store.scm (references/substitutes): Make ITEMS the first argument
of the loop; match on it. Use 'any' to find a matching substitute.
(substitutable-path-info): Clarify docstring about ordering.
