* gnu/packages/zip.scm (zip): Eliminate custom configure phase which copied
and patched the Makefile. Instead add "-f" and "prefix" to make-flags, as
well as "MANDIR". Remove "generic_gcc" from the make-flags, so that it will
not be passed during other phases involving 'make'. Instead replace the
'build' phase with one that specifies the "generic_gcc" target.
* guix/scripts/package.scm (search-path-environment-variables)[manifest-entry->package]:
Use 'find-best-packages-by-name' instead of 'find-packages-by-name'.
On a profile with 140 packages, this reduces execution time of this
procedure from 5.8 seconds to 2.9 seconds (50% improvement.)
* guix/scripts/package.scm (maybe-register-gc-root): New procedure.
* tests/guix-package.sh (profile): Grep the output of "guix gc
--list-live" in a couple of places.
* guix/pki.scm (acl-entry-sexp, acl-sexp): Remove.
(public-keys->acl, current-acl): Return a native sexp.
(acl->public-keys, authorized-key?): Expect ACL to be a native sexp.
* guix/scripts/archive.scm (authorize-key): Convert ACL to
canonical-sexp when writing it.
* guix/scripts/substitute-binary.scm (guix-substitute-binary) <--query>:
Cache the result of (current-acl); pass it to 'valid-narinfo?' calls.
This saves 12% wall-clock time for "guix build emacs -n".
* guix/nar.scm (restore-file-set)[assert-valid-signature]: Rewrite in
terms of 'signature-case'.
* guix/scripts/substitute-binary.scm (narinfo-signature->canonical-sexp):
Call 'leave' instead of 'raise' when SIGNATURE is invalid.
(&nar-signature-error, &nar-invalid-hash-error): Remove.
(assert-valid-signature): Add 'narinfo' parameter; remove 'port'.
Rewrite in terms of 'signature-case' and 'leave'. Mention NARINFO's
URI in error messages. Adjust caller.
(narinfo-sha256): New procedure.
(assert-valid-narinfo): Use it.
(valid-narinfo?): Rewrite using 'narinfo-sha256' and
'signature-case'.
* tests/substitute-binary.scm (assert-valid-signature,
test-error-condition): Remove.
("corrupt signature data", "unauthorized public key", "invalid
signature"): Remove.
* doc/guix.texi (Invoking guix-daemon): Add cross-reference to
"Substitutes".
(Features): Remove footnote about unauthenticated substitutes. Link
to "Substitutes".
(Substitutes): New node.
(Invoking guix build): Link to "Substitutes".
(Packaging Guidelines): Likewise.
* tests/substitute-binary.scm (%narinfo): Set 'URL', 'Compression', and
'NarHash'.
(call-with-narinfo): Create 'example.out' and 'example.nar'.
("query narinfo without signature", "substitute, no signature",
"substitute, authorized key"): New tests.
* tests/substitute-binary.scm (signature-body): Change 'str' parameter
to 'bv', and expect it to be a bytevector.
(%signature-body, %wrong-signature, %acl): Remove.
(signature): Rename to...
(signature-field): ... this. Add 'bv-or-str' parameter. Change 'str'
parameter to #:version. Add #:public-key parameter. Call
'signature-body' directly. Change domain part of the signature to
'example.gnu.org'.
("not a number", "wrong version number", "valid
narinfo-signature->canonical-sexp"): Use 'signature-field' instead of
'signature' or %SIGNATURE.
(test-error-condition): Add 'message-rx' parameter and honor it.
("corrupt signature data", "unauthorized public key", "invalid
signature"): Adjust accordingly.
(narinfo, %signed-narinfo): Remove.
("query narinfo with invalid hash"): Use '%narinfo' and
'signature-field' instead of 'narinfo' and '%signature'.
("query narinfo signed with authorized key", "query narinfo signed
with unauthorized key", "substitute, invalid hash", "substitute,
unauthorized key"): Likewise.
* guix/scripts/substitute-binary.scm (narinfo-signature->canonical-sexp):
Catch 'gcry-error' around 'string->canonical-sexp' call, and re-raise
as a SRFI-35 &message and &nar-signature-error.
(narinfo-maker): Handle when SIGNATURE is #f or an invalid canonical
sexp.
(&nar-signature-error, &nar-invalid-hash-error): New variables.
(assert-valid-signature): Use them. Expect 'signature' to be a
canonical sexp.
(read-narinfo): Remove authentication and authorization checks.
(%signature-line-rx): New variable.
(assert-valid-narinfo, valid-narinfo?): New procedures.
(guix-substitute-binary): Wrap body in 'with-error-handling'.
[valid?]: New procedure.
<--query>: Show only store items of narinfos that match
'valid-narinfo?'.
<--substitute>: Call 'assert-valid-narinfo'.
* tests/substitute-binary.scm (test-error*): Use 'test-equal'.
(%keypair): Remove.
(%public-key, %private-key): Load from signing-key.{pub,sec}.
(signature-body): Add #:public-key parameter.
(call-with-narinfo): New procedure.
(with-narinfo): New macro.
("corrupt signature data", "unauthorized public key", "invalid
signature"): Make the first argument to 'assert-valid-signature' a
canonical sexp.
("invalid hash", "valid read-narinfo", "valid write-narinfo"):
Remove.
("query narinfo with invalid hash", "query narinfo signed with
authorized key", "query narinfo signed with unauthorized key",
"substitute, invalid hash", "substitute, unauthorized key"): New
tests.
* guix/scripts/substitute-binary.scm (<narinfo>)[uri-base]: New field.
(narinfo-maker): Pass CACHE-URL as the 'uri-base' value.
(string->narinfo): Add 'cache-uri' parameter.
(lookup-narinfo)[cache-entry]: Switch to version 1. Add 'cache-uri'
field. Adjust body accordingly.
(remove-expired-cached-narinfos): Switch to version 1 by default.
* guix/scripts/substitute-binary.scm (<narinfo>): Add the 'signature'
and 'contents' fields.
(narinfo-signature->canonical-sexp): New function.
(narinfo-maker): Add the 'signature' argument and use it.
(assert-valid-signature): New function.
(read-narinfo): Support the Signature field.
(write-narinfo): Use 'narinfo-contents'.
(%allow-unauthenticated-substitutes?): New variable.
* guix/base64.scm, tests/base64.scm, tests/substitute-binary.scm: New files.
* Makefile.am (SCM_TESTS): Add tests/base64.scm and
tests/substitute-binary.scm.
(MODULES): Add guix/base64.scm.
* test-env.in: Set 'GUIX_ALLOW_UNAUTHENTICATED_SUBSTITUTES'.
* nix/nix-daemon/guix-daemon.cc (main): When --no-substitutes is used,
clear NIX_SUBSTITUTERS. Before that, and after
89faa5c75c, '--no-substitutes' would
lead to attempts to use 'download-using-manifests.pl', which in
practice would gracelessly fail.
* nix/nix-daemon/guix-daemon.cc (parse_opt): Use 'settings.set' instead
of direct field access for 'buildCores', 'maxBuildJobs', and
'useSubstitutes'.
(main): Call 'settings.update' after 'argp_parse'.
* guix/scripts/offload.scm (transfer-and-offload): Use 'upload' lock
instead of 'bandwidth' around 'send-files' calls, and 'download' lock
around 'retrieve-files' call.
* guix/scripts/offload.scm (remote-pipe): Remove '-z' lsh command line
argument. This makes transfers almost an order of magnitude slower.
OpenSSH's ssh(1) man page notes: "Compression is desirable on modem lines
and other slow connections, but will only slow down things on fast
networks." See also
