From 8971f626f2e69987bea729307adb93a0be243234 Mon Sep 17 00:00:00 2001 From: Caleb Ristvedt Date: Mon, 1 Jun 2020 22:15:21 -0500 Subject: database: 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. --- .dir-locals.el | 2 ++ 1 file changed, 2 insertions(+) (limited to '.dir-locals.el') diff --git a/.dir-locals.el b/.dir-locals.el index d9c81b2a48..b88ec7a795 100644 --- a/.dir-locals.el +++ b/.dir-locals.el @@ -90,7 +90,9 @@ (eval .
