From: Vladimir Davydov <vdavydov.dev@gmail.com> To: kostja@tarantool.org Cc: tarantool-patches@freelists.org Subject: [PATCH 05/25] vinyl: fold vy_delete_impl Date: Fri, 27 Jul 2018 14:29:45 +0300 [thread overview] Message-ID: <b368902d5ab1b29e5c436cd7649d95f789a0475c.1532689066.git.vdavydov.dev@gmail.com> (raw) In-Reply-To: <cover.1532689065.git.vdavydov.dev@gmail.com> In-Reply-To: <cover.1532689065.git.vdavydov.dev@gmail.com> vy_delete_impl helper is only used once in vy_delete and it is rather small so inlining it definitely won't hurt. On the contrary, it will consolidate DELETE logic in one place, making the code easier to follow. --- src/box/vinyl.c | 68 ++++++++++++++++----------------------------------------- 1 file changed, 19 insertions(+), 49 deletions(-) diff --git a/src/box/vinyl.c b/src/box/vinyl.c index 89ca1e78..8c0afd28 100644 --- a/src/box/vinyl.c +++ b/src/box/vinyl.c @@ -1563,47 +1563,6 @@ vy_unique_key_validate(struct vy_lsm *lsm, const char *key, } /** - * Delete the tuple from all LSM trees of the vinyl space. - * @param env Vinyl environment. - * @param tx Current transaction. - * @param space Vinyl space. - * @param tuple Tuple to delete. - * - * @retval 0 Success - * @retval -1 Memory error or the index is not found. - */ -static inline int -vy_delete_impl(struct vy_env *env, struct vy_tx *tx, struct space *space, - const struct tuple *tuple) -{ - struct vy_lsm *pk = vy_lsm_find(space, 0); - if (pk == NULL) - return -1; - /* Primary key is dumped last. */ - assert(!vy_is_committed_one(env, pk)); - struct tuple *delete = - vy_stmt_new_surrogate_delete(pk->mem_format, tuple); - if (delete == NULL) - return -1; - if (vy_tx_set(tx, pk, delete) != 0) - goto error; - - /* At second, delete from seconary indexes. */ - for (uint32_t i = 1; i < space->index_count; ++i) { - struct vy_lsm *lsm = vy_lsm(space->index[i]); - if (vy_is_committed_one(env, lsm)) - continue; - if (vy_tx_set(tx, lsm, delete) != 0) - goto error; - } - tuple_unref(delete); - return 0; -error: - tuple_unref(delete); - return -1; -} - -/** * Execute DELETE in a vinyl space. * @param env Vinyl environment. * @param tx Current transaction. @@ -1650,21 +1609,32 @@ vy_delete(struct vy_env *env, struct vy_tx *tx, struct txn_stmt *stmt, if (stmt->old_tuple == NULL) return 0; } + int rc = 0; + struct tuple *delete; if (has_secondary) { assert(stmt->old_tuple != NULL); - return vy_delete_impl(env, tx, space, stmt->old_tuple); + delete = vy_stmt_new_surrogate_delete(pk->mem_format, + stmt->old_tuple); + if (delete == NULL) + return -1; + for (uint32_t i = 0; i < space->index_count; i++) { + struct vy_lsm *lsm = vy_lsm(space->index[i]); + if (vy_is_committed_one(env, lsm)) + continue; + rc = vy_tx_set(tx, lsm, delete); + if (rc != 0) + break; + } } else { /* Primary is the single index in the space. */ assert(lsm->index_id == 0); - struct tuple *delete = - vy_stmt_new_surrogate_delete_from_key(request->key, - pk->key_def, - pk->mem_format); + delete = vy_stmt_new_surrogate_delete_from_key(request->key, + pk->key_def, pk->mem_format); if (delete == NULL) return -1; - int rc = vy_tx_set(tx, pk, delete); - tuple_unref(delete); - return rc; + rc = vy_tx_set(tx, pk, delete); } + tuple_unref(delete); + return rc; } /** -- 2.11.0
