2020-07-28store: deduplication: Handle fs without d_type support.Mathieu Othacehe
scandir* uses readdir, which means that the file type property can be 'unknown if the underlying file-system does not support d_type. Make sure to fallback to lstat in that case. Fixes: https://issues.guix.gnu.org/issue/42579. * guix/store/deduplication.scm (deduplicate): Handle the case where properties is 'unknown because the underlying file-system does not support d_type.

2020-06-25deduplication: Leave the store permissions unchanged.Ludovic Courtès
Suggested by Caleb Ristvedt <caleb.ristvedt@cune.org>. * guix/store/deduplication.scm (call-with-writable-file): Call THUNK directly when FILE is (%store-directory).
2020-06-25deduplication: Fix default value of #:store in 'deduplicate'.Ludovic Courtès
* guix/store/deduplication.scm (deduplicate): Change #:store default value to (%store-directory).
2020-06-25deduplication: Use 'dynamic-wind' when changing permissions of the parent.Ludovic Courtès
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.
2020-06-22deduplicate: Avoid traversing directories twice.Ludovic Courtès
Until now, we'd call (nar-sha256 file) unconditionally. Thus, if FILE was a directory, we would traverse it for no reason, and then call 'deduplicate' on FILE, which would again traverse it. This change also removes redundant (mkdir-p store) calls from the loop, and avoids 'lstat' calls by using 'scandir*'. * guix/store/deduplication.scm (deduplicate): Add named loop. Move 'mkdir-p' outside the loop. Use 'scandir*' instead of 'scandir'. Do not call 'nar-sha256' when FILE has type 'directory.
2020-06-18database: 'register-items' takes an open database.Ludovic Courtès
* guix/store/database.scm (store-database-directory) (store-database-file): New procedures. (call-with-database): Add call to 'mkdir-p'. (register-items): Add 'db' parameter and remove #:state-directory and #:schema. (register-path): Use 'store-database-file' and 'with-database', and parameterize SQL-SCHEMA. * gnu/build/image.scm (register-closure): Likewise. * gnu/build/vm.scm (register-closure): Likewise. * guix/scripts/pack.scm (store-database)[build]: Likewise.
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.
2020-06-10database: work around guile-sqlite3 bug preventing statement resetCaleb Ristvedt
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).
2020-04-11database: 'reset-timestamps' can optionally preserve permissions.Ludovic Courtès
* guix/store/database.scm (reset-timestamps): Add #:preserve-permissions? and honor it.
2020-02-22deduplication: Use nix-base32 encoding for link names.Ludovic Courtès
Fixes <https://bugs.gnu.org/39725>. * guix/store/deduplication.scm (deduplicate): Use 'bytevector->nix-base32-string' instead of 'bytevector->base16-string'.
2019-09-08daemon: Invoke 'guix gc --list-busy' instead of 'list-runtime-roots'.Ludovic Courtès
* nix/scripts/list-runtime-roots.in: Remove. * guix/store/roots.scm (%proc-directory): New variable. (proc-file-roots, proc-exe-roots, proc-cwd-roots) (proc-fd-roots, proc-maps-roots, proc-environ-roots) (referenced-files, canonicalize-store-item, busy-store-items): New procedures, taken from 'list-runtime-roots.in'. * nix/libstore/globals.hh (Settings)[guixProgram]: New field. * nix/libstore/globals.cc (Settings::processEnvironment): Initialize 'guixProgram'. * nix/libstore/gc.cc (addAdditionalRoots): Drop code related to 'NIX_ROOT_FINDER'.

Set 'GUIX'. * doc/guix.texi (Invoking guix gc): Document '--list-busy'. * guix/scripts/gc.scm (show-help, %options): Add "--list-busy". (guix-gc)[list-busy]: New procedure. Handle the 'list-busy' action.

2018-07-20database: Reset timestamps to one second after the Epoch.Ludovic Courtès
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.
