Suggested by Caleb Ristvedt <caleb.ristvedt@cune.org>.
* guix/store/deduplication.scm (call-with-writable-file): New procedure.
(with-writable-file): New macro.
(replace-with-link): Use it.
Fixes <https://bugs.gnu.org/22883>.
* guix/channels.scm (<channel>)[introduction]: New field.
(<channel-introduction>): New record type.
(%guix-channel-introduction): New variable.
(%default-channels): Use it.
(<channel-metadata>)[keyring-reference]: New field.
(%default-keyring-reference): New variable.
(read-channel-metadata, read-channel-metadata-from-source): Initialize
the 'keyring-reference' field.
(commit-short-id, verify-introductory-commit)
(authenticate-channel): New procedures.
(latest-channel-instance): Call 'authenticate-channel' when CHANNEL has
an introduction.
* tests/channels.scm (gpg+git-available?, commit-id-string): New
procedures.
("authenticate-channel, wrong first commit signer"):
("authenticate-channel, .guix-authorizations"): New tests.
* doc/guix.texi (Invoking guix pull): Mention authentication.
Previously call-with-transaction would both retry when SQLITE_BUSY errors were
thrown and do what its name suggested (start and rollback/commit a
transaction). This changes it to do only what its name implies, which
simplifies its implementation. Retrying is provided by the new
call-with-SQLITE_BUSY-retrying procedure.
* guix/store/database.scm (call-with-transaction): no longer restarts, new
#:restartable? argument controls whether "begin" or "begin immediate" is
used.
(call-with-SQLITE_BUSY-retrying, call-with-retrying-transaction,
call-with-retrying-savepoint): new procedures.
(register-items): use call-with-retrying-transaction to preserve old
behavior.
* .dir-locals.el (call-with-retrying-transaction,
call-with-retrying-savepoint): add indentation information.
update-or-insert can break if an insert occurs between when it decides whether
to update or insert and when it actually performs that operation. Putting the
check and the update/insert operation in the same transaction ensures that the
update/insert will only succeed if no other write has occurred in the middle.
* guix/store/database.scm (call-with-savepoint): new procedure.
(update-or-insert): use call-with-savepoint to ensure the read and the
insert/update occur within the same transaction.
Most of our queries would fail to finalize their statements properly if sqlite
returned an error during their execution. This resolves that, and also makes
them somewhat more concise as a side-effect.
This also makes some small changes to improve certain queries where behavior
was strange or overly verbose.
* guix/store/database.scm (call-with-statement): new procedure.
(with-statement): new macro.
(last-insert-row-id, path-id, update-or-insert, add-references): rewrite to
use with-statement.
(update-or-insert): factor last-insert-row-id out of the end of both
branches.
(add-references): remove pointless last-insert-row-id call.
* .dir-locals.el (with-statement): add indenting information.
* guix/ui.scm (call-with-paginated-output-port): New procedure.
(with-paginated-output-port): New macro.
(display-search-results): Use it instead of displaying a hint.
* guix/gexp.scm (<system-binding>): New record type.
(let-system): New macro.
(system-binding-compiler): New procedure.
(default-expander): Add 'self-quoting?' case.
(self-quoting?): New procedure.
(lower-inputs): Add 'filterm'. Pass the result of
'mapm/accumulate-builds' through FILTERM.
(gexp->sexp)[self-quoting?]: Remove.
* tests/gexp.scm ("let-system", "let-system, target")
("let-system, ungexp-native, target")
("let-system, nested"): New tests.
* doc/guix.texi (G-Expressions): Document it.
* guix/store.scm (current-build-prompt): New variable.
(call-with-build-handler, invoke-build-handler): New procedures.
(with-build-handler): New macro.
* tests/store.scm ("with-build-handler"): New test.
* guix/gexp.scm (<parameterized>): New record type.
(with-parameters): New macro.
(compile-parameterized): New gexp compiler.
* tests/gexp.scm ("with-parameters for %current-system")
("with-parameters for %current-target-system")
("with-parameters + file-append"): New tests.
* doc/guix.texi (G-Expressions): Document it.
* guix/store/database.scm (SQLITE_BUSY, register-output-sql): New variables.
(add-references): Don't try finalizing after each use, only after all the
uses (otherwise a finalized statement would be used if #:cache? was #f).
(call-with-transaction): New procedure.
(register-items): Use call-with-transaction to prevent broken intermediate
states from being visible.
* .dir-locals.el (call-with-transaction): indent it.

("self-contained-tarball"): Wrap in 'with-external-store'.
* tests/guix-pack.sh: Connect to the external store, if possible, by
setting NIX_STORE_DIR and GUIX_DAEMON_SOCKET. Remove most uses of
'--bootstrap'.
Fixes <http://bugs.gnu.org/26949>.

* guix/build/union.scm (file-is-directory?): Return #f when FILE does
not exist or is a dangling symlink.
(file=?): Pass #f as a second argument to 'stat'; return #f when both
ST1 or ST2 is #f.
* tests/profiles.scm (test-equalm): New macro.
("union vs. dangling symlink"): New test.
Users using a non-English environment may have set this to `nil´, which
leads to fill-paragraph removing the second space.
* .dir-locals.el: Set sentence-end-double-space to true.
