2020-10-19maint: update-guix-package: Prevent accidentally breaking guix pull.Maxim Cournoyer
Fixes <https://issues.guix.gnu.org/43893>. This changes the 'update-guix-package' tool so that it: 1. Always uses a clean checkout to compute the hash of the updated 'guix' package. 2. Ensures the commit used in the updated 'guix' package definition has already been pushed upstream. * build-aux/update-guix-package.scm (%savannah-guix-git-repo-push-url): New variable. (with-input-pipe-to-string, with-temporary-git-worktree): New syntaxes. (find-origin-remote, git-add-worktree): New procedures. (commit-already-pushed?): New predicate. (main): Check the commit used has already been pushed upstream and compute the hash from a clean checkout. * doc/contributing.texi (Updating the Guix Package): Document it. * .dir-locals.el (scheme-mode): Fix indentation of with-temporary-git-worktree.
2020-09-14deduplication: pass store directory to replace-with-link.Caleb Ristvedt
This causes with-writable-file to take into consideration the actual store being used, as passed to 'deduplicate', rather than whatever (%store-directory) may return. * guix/store/deduplication.scm (replace-with-link): new keyword argument 'store'. Pass to with-writable-file. (with-writable-file, call-with-writable-file): new store argument. (deduplicate): pass store to replace-with-link. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
2020-09-14.dir-locals.el: fix call-with-{retrying-}transaction indenting.Caleb Ristvedt
* .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>

2020-06-25deduplication: Use 'dynamic-wind' when changing permissions of the parent.Ludovic Courtès

2020-06-16channels: 'latest-channel-instance' authenticates Git checkouts.Ludovic Courtès

2020-06-10database: separate transaction-handling and retry-handling.Caleb Ristvedt
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.
2020-06-10database: ensure update-or-insert is run within a transactionCaleb Ristvedt
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.
2020-06-10database: rewrite query procedures in terms of with-statement.Caleb Ristvedt
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.
