|
2014-12-22
| ||
| 18:41 | [a3d0ae1d] part of check-in [7a97826f] Redefine the way PRAGMA data_version works: It continues to change when any other connection commits, including shared-cache connections, but does not change if the local connection commits. (check-in: [7a97826f] user: drh branch: trunk, size: 30906) | |
|

2014-09-26
| ||
| 02:41 | [1bd79571] part of check-in [83913515] Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. (check-in: [83913515] user: drh branch: trunk, size: 30523) | |

| ||
| 23:40 | [d1784d1e] part of check-in [968fec44] Combine the various boolean fields of the BtCursor object into a single bit-vector. This allows setting or clearing more than one boolean at a time and makes the overflow-pgno-cache branch faster than trunk on speedtest1. (check-in: [968fec44] user: drh branch: overflow-pgno-cache, size: 30422) | |
| 20:33 | [22a8f079] part of check-in [da591985] Enable the b-tree cursor object's overflow page-number cache, which is normally enabled only for incr-blob cursors, for all cursors. (check-in: [da591985] user: dan branch: overflow-pgno-cache, size: 30353) | |
|
2014-02-12
| ||
| 21:31 | [0be66063] part of check-in [56bc5ce8] Remove the "rowid cache" that sought to remember the largest rowid for a table and thereby speed up OP_NewRowid. That cache was ineffective. Removing it results in a performance increase of 0.4%, less memory usage, and a slightly smaller library size. (check-in: [56bc5ce8] user: drh branch: trunk, size: 30202) | |
|
2013-10-01

|
2013-02-23
| ||
| 16:40 | [eecc84f0] part of check-in [b73847f1] If a rollback mode transaction reduces the size of the database file, avoid actually truncating the file until after the transaction has been committed (but before the db has been unlocked). This means pages that are removed from the database by truncating the file need not be journalled. (check-in: [b73847f1] user: dan branch: incr-vacuum-opt, size: 29908) | |
|
2012-08-06
| ||
| 18:50 | [4e5c2bd0] part of check-in [d045f8b2] When reusing pages as part of creating a new index, allocate the leaves from each free-list trunk page in ascending order, instead of trying to maximize localization for each individual allocation. This increases the chance that pages will be written to disk in ascending order by a large CREATE INDEX statement, improving overall performance. (check-in: [d045f8b2] user: dan branch: sorter-coalesce-writes, size: 29848) | |

|
2011-04-04
| ||
| 00:14 | [6714ce2f] part of check-in [d81708f7] Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: [d81708f7] user: drh branch: trunk, size: 29100) | |

2010-08-30
| ||
| 22:15 | [c424f2f1] part of check-in [4fead8e7] Provide hints to the btree layer during the creation of transient tables for when it is possible for those tables to use a hash rather than a binary tree. No use is currently made of those hints, though assert() statement verify their accuracy. (check-in: [4fead8e7] user: drh branch: trunk, size: 29034) | |
