* deduplication: Detect holes and create sparse files.Ludovic Courtès2024-05-25
| | | | | | | | | | | | | | | | | This reduces disk usage of sparse files that are substituted such as Guile object files (ELF files). As of Guile 3.0.9, .go files are sparse due to ELF sections being aligned on 64 KiB boundaries. This reduces disk usage reported by “du -sh” by 9% for the ‘guix’ package, by 23% for ‘guile’, and by 35% for ‘guile-git’. * guix/store/deduplication.scm (hole-size, find-holes): New procedures. (tee)[seekable?]: New variable. [read!]: Add case when SEEKABLE? is true. * tests/store-deduplication.scm (cartesian-product): New procedure. ("copy-file/deduplicate, sparse files (holes: ~a/~a/~a)"): New test set. Change-Id: Iad2ab7830dcb1220e2026f4a127a6c718afa8964

* store: database: Refactor sqlite-register.Christopher Baines2024-04-03

* store: database: Stop finalizing prepared statements.Christopher Baines2024-04-03
| | | | | | | | | | | | | | | | Especially since we're asking for these to be cached. Management of prepared statements isn't trivial, since you don't want to keep them forever as this can lead to poor query performance, but I don't think that finalizing them immediately is the right solution. Change-Id: I61706b4d09d771835bb8f074b8f6a6ee871f5e2d * guix/store/database.scm (sqlite-step-and-reset): New procedure.

* store: database: Inline SQL to where it's used.Christopher Baines2024-04-03

(path-id, update-or-insert, add-references): Include SQL. Change-Id: I53b4ab973be8d0cd10a0f35ba25972f1c9680353
* store: database: Remove with-statement and associated code.Christopher Baines2024-04-03
| | | | | | | | | | | | | | | | | | I think using dynamic-wind to finalize all statements is the wrong approach. Firstly it would be good to allow reseting statements rather than finalizing them. Then for the problem of handling errors, the approach I've settled on in the build coordinator is to close the database connection, since that'll trigger guile-sqlite3 to finalize all the cached statements. This reverts commit 5d6e2255286e591def122ec2f4a3cbda497fea21. * .dir-locals.el (scheme-mode): Remove with-statement. * guix/store/database.scm (call-with-statement): Remove procedure. (with-statement): Remove syntax rule. (call-with-transaction, last-insert-row-id, path-id, update-or-insert, add-references): Don't use with-statement.

* store: database: Remove call-with-savepoint and associated code.Christopher Baines2024-04-03
| | | | | | | | | | | | | | | | | | While care does need to be taken with making updates or inserts to the ValidPaths table, I think that trying to ensure this within update-or-insert is the wrong approach. Instead, when working with the store database, only one connection should be used to make changes to the database and those changes should happen in transactions that ideally begin immediately. This reverts commit 37545de4a3bf59611c184b31506fe9a16abe4c8b. * .dir-locals.el (scheme-mode): Remove entries for call-with-savepoint and call-with-retrying-savepoint. * guix/store/database.scm (call-with-savepoint, call-with-retrying-savepoint): Remove procedures. (update-or-insert): Remove use of call-with-savepoint. Change-Id: I2f986e8623d8235a90c40d5f219c1292c1ab157b

| * daemon: Do not deduplicate files smaller than 8 KiB.Ludovic Courtès2021-11-16

* database: register-items: reduce transaction scope.Christopher Baines2020-09-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | It was made transactional in a4678c6ba18d8dbd79d931f80426eebf61be7ebe, with the reasoning to prevent broken intermediate states from being visible. I think this means something like an entry being in ValidPaths, but the Refs not being inserted. Using a transaction for this makes sense, but I think using one single transaction for the whole register-items call is unnecessary to avoid broken states from being visible, and could block other writes to the store database while register-items is running. Because the deduplication and resetting timestamps happens within the transaction as well, even though these things don't involve the database, writes to the database will still be blocked while this is happening. To reduce the potential for register-items to block other writers to the database for extended periods, this commit moves the transaction to just wrap the call to sqlite-register. This is the one place where writes occur, so that should prevent the broken intermediate states issue above. The one difference this will make is some of the registered items will be visible to other connections while others may be still being added. I think this is OK, as it's equivalent to just registering different items. * guix/store/database.scm (register-items): Reduce transaction scope. Signed-off-by: Ludovic Courtès <ludo@gnu.org>

| | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | 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.

* database: work around guile-sqlite3 bug preventing statement resetCaleb Ristvedt2020-06-10
| | | | | | | | | | | | | guile-sqlite3 provides statement caching, making it unnecessary for sqlite to keep re-preparing statements that are frequently used. Unfortunately it doesn't quite emulate the semantics of sqlite_finalize properly, because it doesn't cause a commit if the statement being finalized is the last "active" statement (see https://notabug.org/guile-sqlite3/guile-sqlite3/issues/12). We work around this by wrapping sqlite-finalize with our own version that ensures sqlite-reset is called, which does The Right Thing™. * guix/store/database.scm (sqlite-finalize): new procedure that shadows the sqlite-finalize from (sqlite3).
