guix.git/guix/store/database.scm, branch master

database: Make 'register-items' transactional.

2019-03-06T23:00:18Z

* 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. Signed-off-by: Ludovic Courtès

database: Use "write-ahead log" mode and set a long "busy timeout".

2018-12-21T22:50:13Z

This should avoid "database is locked" errors when there's a lot of concurrency, for instance when offloading simultaneously a lot of builds. * guix/store/database.scm (call-with-database): Add two 'sqlite-exec' calls to set 'journal_mode' and 'busy_timeout'.

Update Guile-SQLite3 URL everywhere.

2018-11-23T14:42:00Z

* README: Update Guile-SQLite3 URL. * doc/guix.texi (Requirements): Likewise. * guix/store/database.scm (sqlite-exec): Likewise. * m4/guix.m4 (GUIX_CHECK_GUILE_SQLITE3): Likewise.

nar: Access the database instead of connecting to the daemon.

2018-11-13T13:59:45Z

* guix/store/database.scm (%default-database-file): New variable. (path-id): Export. * guix/nar.scm (finalize-store-file): Use 'with-database' instead of 'with-store', and use 'path-id' instead of 'valid-path?'.

database: Register each store item only once.

2018-09-23T21:34:17Z

Fixes . Reported by Leo Famulari. * guix/store/database.scm (register-items): Check whether TO-REGISTER is in DB by calling 'path-id', and skip the reset-timestamps, registration, and deduplication phases when it is.

database: 'register-items' shows a progress bar.

2018-09-23T21:34:16Z

* guix/store/database.scm (register-items): Add #:log-port. Use 'progress-reporter/bar' to show a progress report. (register-path): Pass #:log-port to 'register-items'.

database: Reset timestamps to one second after the Epoch.

2018-07-20T13:01:33Z

Previously, store items registered in the database by this code (for instance, store items retrieved by 'guix offload' and passed to 'restore-file-set') would have an mtime of 0 instead of 1. This would cause problems for things like .go files: Guile would consider them to be older than the corresponding .scm file, and consequently it would ignore them and possibly use another (incorrect) .go file. Reported by Ricardo Wurmus. * guix/store/database.scm (reset-timestamps): Pass 1, not 0, to 'utime'. * tests/store-database.scm ("register-path"): Check the mtime of FILE and REF.

database: 'reset-timestamps' now correctly handles symlinks.

2018-07-03T15:50:04Z

* guix/store/database.scm (reset-timestamps): Use 'utime' with AT_SYMLINK_NOFOLLOW for symlinks.

database: Allow for deterministic database construction.

2018-06-14T09:17:00Z

Fixes . * guix/store/database.scm (sqlite-register): Add #:time. (%epoch): New variable. (register-items): Add #:registration-time. Pass #:time to 'sqlite-register'. * gnu/build/install.scm (register-closure): Pass #:registration-time.

install: Use 'reset-timestamps' from (guix store database).

2018-06-14T09:17:00Z

* gnu/build/install.scm (reset-timestamps): Remove. * gnu/build/vm.scm: Use 'reset-timestamps' from (guix store database).
