23:28
Performance improvements on memory copies inside of btree by moving 2 bytes at a time instead of just 1 byte at a time. (check-in: 897f56a158 user: drh tags: trunk)
21:34
Performance enhancement to the blob-literal tokenizer. (check-in: 61aa2031f1 user: drh tags: trunk)
20:11
Create and use a function especially for adding the ParseSchema opcode. This gives a small reduction in code and a small performance increase. (check-in: 957b2ab67c user: drh tags: trunk)
17:50
Factor an "if" out of a loop in balance_nonroot() for about a 1% performance increase. (check-in: 1bd72d0c61 user: drh tags: trunk)
14:19
Hush some harmless compiler warnings in the URI parsing logic. (check-in: 0206bc6f87 user: drh tags: trunk)
13:28
Include more detailed version information in the command-line shell output. (check-in: 049c3c42fd user: drh tags: trunk)
13:06
Add shell scripts used for testing compiler warnings (tool/warnings.sh), for verifying that the library exports the correct symbols (tool/symbols.sh), and to demonstrate building a full-featured command-line shell (tool/build-shell.sh). (check-in: 3aca9a92c8 user: drh tags: trunk)
13:02
Fix the build when using SQLITE_OMIT_PRAGMA. (check-in: 051f4635bf user: drh tags: trunk)

Add a missing check for out-of-memory in the lemon code generator. (check-in: efb20b9da6 user: drh tags: trunk)
13:04
Merge the read-only shared memory branch into trunk. After this merge, an unprivileged process can open WAL-mode databases owned by another user as long as a database connection with write permission exists on the database file and if the readonly_shm=1 URI query parameter is supplied.

2011-06-01
20:13
Make use of the sqlite3GetBoolean() interface for more robust processing of the readonly_shm query parameter inside of unixShmMap(). (Closed-Leaf check-in: 1f930d7e04 user: drh tags: wal-readonly)
20:01
Simplify the wal-readonly branch so that it does not require changes to anything other than os_unix.c and wal.c and a couple of new error codes. (check-in: d6b4709de4 user: drh tags: wal-readonly)
19:44
Pull the latest trunk changes into the wal-readonly branch. (check-in: 0b63b71357 user: drh tags: wal-readonly)
19:16
Avoid unnecessary duplication of SQL parameter names. (check-in: e704e8690a user: drh tags: trunk)
18:15
Refactor the SQL parameter processing so that parameter names for values that are optimized out of the prepare statement are not forgotten. (check-in: b3aaf715b6 user: drh tags: trunk)
2011-05-31
17:08
Merge the latest trunk changes into the wal-readonly branch. (check-in: 2c6b5a28e3 user: drh tags: wal-readonly)
16:50

11:56
Update the documentation to state that any parameter that is optimized out of a prepared statement becomes an anonymous parameter for which sqlite3_bind_parameter_name() returns NULL. (check-in: 701b8a23e3 user: drh tags: trunk)
2011-05-30
23:42
Minor performance improvements. (check-in: f9950c6af1 user: drh tags: trunk)

2011-05-24
15:36
Do not invoke the xRollbackTo or xRelease methods of a virtual table without having first invoked an appropriate xSavepoint method. Add assert() statements to FTS3/4 to verify that this is happening in all cases. (check-in: 651ef24249 user: drh tags: trunk)

Adjustments to documentation hyperlinks to accommodate the new VFS documentation. (check-in: 139a8f53ae user: drh tags: trunk)

20:36
Add the ability to limit filenames to 8+3 using the SQLITE_ENABLE_8_3_NAMES compile-time option together with a URI parameter of "8_3_names=1". (check-in: 96d6098560 user: drh tags: trunk)
