13:28
Remove the use of htonl() in the previous check-in due to linkage issues. Add the get2byteAligned() macro and use it for access to the cell offsets on btree pages for about a 1% performance gain. (check-in: 79ff36b717 user: drh tags: bswap-functions)
12:47
Make use of htonl() and __builtin_bswap32() for faster implementations of sqlite3Get4byte() and sqlite3Put4byte(). (check-in: bc27ebd7f7 user: drh tags: bswap-functions)
11:07

03:57
Optimization to the sqlite3PcacheFetch() logic. (check-in: d9a0481ce0 user: drh tags: trunk)
03:34

03:18
Implement sqlite3Strlen30() using strlen() from the C library. (check-in: 8001aa52bd user: drh tags: trunk)
03:13
Change sqlite3ApiExit() so that its first argument is never NULL. (check-in: 791b706ec6 user: drh tags: trunk)
02:47
Put BtCursor objects on a singly-linked list instead of a doubly-linked list. Add the BTCF_Multiple flag. Only invoke saveAllCursors() when using a cursor that has BTCF_Multiple set. (check-in: 429ccef2b3 user: drh tags: trunk)
01:25
Convert several 5-year-old and older NEVER() macros into assert(). (check-in: ed54c14ea8 user: drh tags: trunk)
2015-06-29
23:01
From sqlite3BtreeInsert(), bypass the btreeMoveto() routine for table inserts and go directly to sqlite3BtreeMovetoUnpacked(). (check-in: 53fe685d56 user: drh tags: trunk)
20:53
Add a bypass path in sqlite3PagerWrite() for pages with the PGHDR_WRITEABLE bit set, for about a 1% performance increase. (check-in: ba425a6abb user: drh tags: trunk)

Simplifications and performance improvement in pager_write(). (check-in: ab7aeeead3 user: drh tags: trunk)
04:21
Add the new PGHDR_CLEAN bit to PgHdr.flags in pcache.c. This bit is always the opposite of PGHDR_DIRTY. Use the extra bit to avoid a comparison for a small performance boost. (check-in: 8619fc346d user: drh tags: trunk)
03:28
Very small size reduction and performance increase in sqlite3BitvecTest(). (check-in: 9b3a7281bd user: drh tags: trunk)

19:45
Performance improvements in moveToChild() by shifting some work over to getAndInitPage(). Net improvement is about 800K cycles at cost of 30 bytes. (check-in: 1956a4ce8e user: drh tags: trunk)
15:51
Manually inline the call from getAndInitPage() to btreeGetPage() for a savings of 2.5 million cycles at a cost of less than 100 bytes. (check-in: 7f65b96b40 user: drh tags: trunk)
14:59

Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine.

15:10
Disallow the use of "rowid" in CTEs - it has never worked correctly and it makes no sense, so we might as well make it an explicit error. Also: add the PRAGMA cell_size_check=ON command. (check-in: 19e2cebc12 user: drh tags: trunk)
14:21
A different approach to preventing buffer overreads when comparing a vector of values with a corrupt index record that spans at least one overflow page. (Closed-Leaf check-in: 7e9e1b6123 user: dan tags: avoid-buffer-overread)
13:06
CTEs have never had working rowids. So disallow the use of the "rowid" column within CTEs. (Closed-Leaf check-in: 0055df0445 user: drh tags: no-rowid-in-cte)
03:46
Add the "PRAGMA cell_size_check=ON" command. (Closed-Leaf check-in: 2ead43f074 user: drh tags: cell-size-check-pragma)
2015-05-26
20:31
