| 19:04 | Change the description of how sqlite3_progress_handler() works so that the N parameter is "approximate". This aligns with the current implementation. This is a documentation change only. No changes to code. check-in: 7d829bde user: drh tags: trunk | |
| 15:31 | Merge recent trunk changes (such as the query_only PRAGMA, the defer_foreign_keys PRAGMA, and the SQLITE_DBSTATUS_DEFERRED_FKS parameter to sqlite3_db_status()) into the sessions branch. check-in: 8dfc0b78 user: drh tags: sessions | |
| 15:22 | Add the experimental "query_only" pragma. check-in: 6557c407 user: drh tags: trunk | |
| 15:03 | Add the "defer_foreign_keys" pragma and the SQLITE_DBSTATUS_DEFERRED_FKS value for sqlite3_db_status(). This is a cherry-pick of a sequence of five checkins in the sessions branch between [1d44e5d3c2] and [d39e65fe70]. check-in: 527121ac user: drh tags: trunk | |
| 13:49 | Remove the undocumented sqlite3_foreign_key_check() API and replace it with sqlite3_db_status(db, SQLITE_DBSTATUS_DEFERRED_FKS, ...). Add test cases for the new functionality. check-in: d39e65fe user: drh tags: sessions | |
| 12:19 | Rename the SQLITE_DeferForeignKeys macro to shorter SQLITE_DeferFKs. Move the "defer_foreign_keys" pragma into the flagPragma() routine. check-in: 3a2ab74c user: drh tags: sessions | |
| 03:09 | Environment variable names in nmake must be in all uppercase. check-in: 0328e873 user: mistachkin tags: vsix2013 | |

| 03:05 | Run progress callback checks less frequently in the main VDBE evaluation loop. This makes up for the extra CPU cycles used to increment the cycle counter for SQLITE_STMTSTATUS_VM_STEP. check-in: 3e8b0201 user: drh tags: trunk | |
|

| 17:57 | Drop any existing mapping of the database file when exiting the pager "error state", as it may at this point be too large for the database file. Do not invoke file-control MMAP_SIZE if the database file handle does not support xFetch and xUnfetch (on the grounds that xUnfetch(0) calls to invalidate the mapping cannot be made). check-in: 0ae7e75b user: dan tags: trunk | |
|
2013-07-05
| ||
| 19:16 | Fix two test script problems revealed by permutations.test. check-in: 60cf7e44 user: dan tags: trunk | |

|
2013-07-03
| ||
| 19:53 | Experimental change to the handling of foreign key constraint violations when applying a changeset: all foreign keys, immediate and deferred, are deferred until the end of the transaction (or sub-transaction) opened by the sqlite3changeset_apply(). A single call to the conflict-handler (if any) is made if any FK constraint violations are still present in the database at this point. The conflict-handler may choose to rollback the changeset or to apply it, constraint violations and all. check-in: 1d44e5d3 user: dan tags: sessions | |
|
2013-07-02

| 17:27 | Add a missing test that prevented double LEFT JOINs with transitive constraints from working correctly. Fix for ticket [868145d012]. check-in: 72919ec3 user: drh tags: trunk | |
| 11:05 | Further minor comment corrections and enhancements in where.c. check-in: 0d68d4d0 user: drh tags: trunk | |

|
2013-06-29
| ||
| 15:40 | Fix the build of the command-line shell on windows. Windows uses "_pclose" rather than "pclose" as the pointer to the function that closes a popen pipe. check-in: b003b2b2 user: drh tags: trunk | |
|
2013-06-28
| ||
| 23:55 | Issue the new SQLITE_WARNING_AUTOINDEX warning on the SQLite log whenever an automatic index is created. check-in: 338826ef user: drh tags: trunk | |
| 21:12 | Add the SQLITE_DEFAULT_AUTOMATIC_INDEX compile-time option, which if set to zero turns automatic indices off by default. Increase the estimated cost of an automatic index. Additional minor refactoring of the automatic index code. check-in: 459b3179 user: drh tags: trunk | |
| 19:41 | Allow read transactions to be freely opened and closed by SQL statements run from within the implementation of user-functions if the user-function is called by a SELECT statement that does not access any database tables (e.g. "SELECT user_function();"). check-in: f308c485 user: dan tags: trunk | |
| 17:29 | Add a bit to the SQLITE_TESTCTRL_OPTIMIZATIONS option for sqlite3_file_control() that will disable the use of SQLITE_STAT3 information in the query planner. check-in: 60c19b86 user: drh tags: trunk | |
| 13:43 | Fix an issue with the OmitNoopJoin optimization and add test cases that are specifically for that optimization. check-in: 5480d124 user: drh tags: trunk | |
| 01:24 | Refactor the Vdbe.noIO field as Vdbe.bIsReader. The meaning is inverted. check-in: 59f98c5c user: drh tags: trunk | |
|
2013-06-27
| ||
| 23:54 | Refactor names of fields in the sqlite3 object: "activeVdbeCnt" becomes "nVdbeActive". Related fields becomes "nVdbeRead", "nVdbeWrite", and "nVdbeExec". check-in: 14f79696 user: drh tags: trunk | |

| 17:40 | Make sure that sqlite3_stmt_readonly reports false for PRAGMA journal_mode and PRAGMA wal_checkpoint. Ticket [a589ec069e3]. Also keep track of whether a prepared statement does no reading or writing. check-in: 1937fd8e user: drh tags: trunk | |
| 14:24 | Add a test to ensure that if BEGIN IMMEDIATE fails with SQLITE_BUSY, it does not leave the user with an open read transaction (unless one was already open). check-in: 22bced36 user: dan tags: trunk | |
| 14:07 | If the filename argument to the ".import" command in the command-line shell begins with '|' then treat it as an input pipe rather than a file. check-in: 4c02b344 user: drh tags: trunk | |
| 13:26 | Improved handling of backslash escapes on double-quoted arguments to dot-commands in the command-line shell. check-in: 656a1fe5 user: drh tags: trunk | |
| 13:01 | The undocumented and unsupported ".selftest" command in the command-line shell utility is now only available if compiled with SQLITE_DEBUG. Also fix a windows compiler warning in that command. check-in: e88fd5b2 user: drh tags: trunk | |
| 11:46 | Add extended error code SQLITE_BUSY_SNAPSHOT - returned in WAL mode when a read-transaction cannot be upgraded to a write-transaction because it is reading from a snapshot other than the most recently committed. check-in: 361c2296 user: dan tags: trunk | |
|
2013-06-26
| ||
| 22:46 | Update the ".import" command of the command-line shell so that it can accept field values that span multiple lines and so that it issues error messages if the input text does not strictly conform to RFC4180. check-in: 93f63215 user: drh tags: trunk | |
| 18:04 | Add the "vtshim" extension, implementing a wrapper around the virtual table interface to make it Disposable for the CLR. No changes to the core. check-in: 6c3839ef user: drh tags: trunk | |
| 16:30 | Update the boundary3.tcl script so that it can be run with tcl 8.5 or 8.6 to regenerate boundary3.test. check-in: ebac5afa user: dan tags: trunk | |
| 13:31 | Bring the sessions branch up-to-date with all the latest trunk changes. check-in: 086a1272 user: drh tags: sessions | |
| 13:22 | Add the SQLITE_STMTSTATUS_VM_STEPS option for sqlite3_stmt_status(). check-in: bd4267f1 user: drh tags: trunk | |

| 11:43 | Cut over the next generation query planner. Increase the version number to 3.8.0. check-in: 0fe31f60 user: drh tags: trunk | |
| 00:34 | Fix an uninitialized variable detected by valgrind. Unclear whether or not this should apply to trunk. Closed-Leaf check-in: 19ab4811 user: drh tags: nextgen-query-plan-exp | |
|
2013-06-25
| ||
| 22:01 | Add a new (experimental) sqlite3_stmt_status() verb that returns the number of VM steps. Closed-Leaf check-in: f1366bab user: drh tags: status-vm-step | |

| 19:39 | Enhance error message handling for the vtshim module. Closed-Leaf check-in: b4a0d532 user: mistachkin tags: disposable-vtable | |
| 19:29 | Merge in the latest changes from trunk. Simplify the implementation of the tointeger() and toreal() functions. Fix test cases and put unambiguous labels on all testcase names. check-in: 9b837b05 user: drh tags: toTypeFuncs | |
| 18:36 | Remove an unused function declaration from the FTS3 source code. check-in: 096ae1d8 user: drh tags: trunk | |
| 18:32 | Merge updates from trunk. check-in: fa2a91e6 user: mistachkin tags: toTypeFuncs | |

| 07:54 | Update comments and package flavor error message. check-in: 9d1b9618 user: mistachkin tags: vsix2013 | |
| 02:15 | Only eliminate inner loops of a JOIN if they are the RHS of a LEFT JOIN and if they give no more than a single result. This appears to give correct answers in all cases. check-in: d7a25cc7 user: drh tags: omit-join-table-opt | |
| 02:05 | Attempt to disable inner loops of a join that do not generate output. This does not work, since the inner loops might run zero times and thus inhibit all output. Needs to be enhanced to work only for LEFT JOINs or when we know that the inner loop will always run at least once. check-in: ca839723 user: drh tags: omit-join-table-opt | |
| 00:35 | Modify the query planner interface so that it always passes in the result set. This is the first step toward adding an optimization that will omit tables from a join that do not contribute to the result. check-in: 2c2577e6 user: drh tags: omit-join-table-opt | |
|
2013-06-20

|
2013-06-19
| ||
| 23:48 | Merge in trunk changes to os_unix.c that allow the code to build on unix platforms that lack posix_fallocate(). check-in: bf576406 user: drh tags: nextgen-query-plan-exp | |
| 20:13 | Add the languageid_bits= option to fts. Still some problems to work out. check-in: d36d7e68 user: dan tags: fts-languageid-bits | |
| 18:01 | Add in the cost of doing a table lookup on OR searches. Make test case changes to deal with difference in STAT3 behavior. check-in: d97898e8 user: drh tags: nextgen-query-plan-exp | |
| 14:49 | Only default HAVE_POSIX_FALLOCATE on for linux, and then only if it is not previously defined. check-in: 2b2ade92 user: drh tags: trunk | |
