. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Caleb Ristvedt 2020-09-14.dir-locals.el: fix call-with-{retrying-}transaction indenting....* .dir-locals.el (call-with-transaction, call-with-retrying-transaction): change scheme-indent-function property from 2 to 1. Signed-off-by: Ludovic Courtès <ludo@gnu.org> Caleb Ristvedt 2020-08-26.dir-locals.el: Add indentation rule for 'package/inherit'....* .dir-locals.el (scheme-mode): Add 'package/inherit'. Ludovic Courtès 2020-06-25deduplication: Use 'dynamic-wind' when changing permissions of the parent....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. Ludovic Courtès 2020-06-16channels: 'latest-channel-instance' authenticates Git checkouts....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. Ludovic Courtès 2020-06-10database: separate transaction-handling and retry-handling....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. Caleb Ristvedt 2020-06-10database: ensure update-or-insert is run within a transaction...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. Caleb Ristvedt 2020-06-10database: rewrite query procedures in terms of with-statement....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. Caleb Ristvedt 2020-06-06ui: 'display-search-results' automatically invokes the pager....* 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. Ludovic Courtès 2020-06-05git-authenticate: Add tests....* guix/tests/git.scm (call-with-environment-variables) (with-environment-variables): Remove. * guix/tests/git.scm (populate-git-repository): Add clauses for signed commits and signed merges. * guix/tests/gnupg.scm: New file. * tests/git-authenticate.scm: New file. * tests/ed25519bis.key, tests/ed25519bis.sec: New files. * Makefile.am (dist_noinst_DATA): Add 'guix/tests/gnupg.scm'. (SCM_TESTS): Add 'tests/git-authenticate.scm'. (EXTRA_DIST): Add tests/ed25519bis.{key,sec}. Ludovic Courtès 2020-05-16gexp: Add 'let-system'....* 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.

Ludovic Courtès 2019-11-29ui: Factorize 'with-profile-lock'....* guix/ui.scm (profile-lock-handler, profile-lock-file): New procedures. (with-profile-lock): New macro. * guix/scripts/package.scm (process-actions): Use 'with-profile-lock' instead of 'with-file-lock/no-wait'. * guix/scripts/pull.scm (guix-pull): Likewise. Ludovic Courtès 2019-11-19pull: Acquire a lock for the target profile....This is a followup to b1fb663404894268b5ee92c040f12c52c0bee425. * guix/scripts/pull.scm (guix-pull): Wrap 'run-with-store' call in 'with-file-lock/no-wait'.

(bake-narinfo+nar): Add lzip. (nar-response-port): Likewise. (string->compression-type): New procedure. (make-request-handler): Generalize /nar/gzip handler to handle /nar/lzip as well. * tests/publish.scm ("/nar/lzip/*"): New test. ("/*.narinfo with lzip compression"): New test. * doc/guix.texi (Invoking guix publish): Document it. (Requirements): Mention lzlib.
