Infrastructure for an extension C-library to implement sqlite3_db_dump() and a corresponding "dbdump" command-line utility - both of which do the same work as the ".dump" command of the CLI. (check-in: 74c5ace4 user: drh tags: dbdump)
18:31
Merge all recent changes from trunk. (check-in: 3d04b2cd user: drh tags: apple-osx)
18:24
In the output of the ".dump" command in the CLI, quote newline and carriage-return characters using the char() function, so that they do not get eaten by end-of-line processing logic in the OS or in other command-line utilities and/or libraries. (check-in: 68f6dc7a user: drh tags: trunk)
17:37
Fix the sqlite3TreeViewSelect() routine so that it works with a null pointer to the Select object. (check-in: 9034cf7e user: drh tags: trunk)

13:45
In the OSSFuzz test module, invoke the progress handler much more frequently so that timeouts are detected punctually even if the test script is running opcodes that individually take a long time (for example, an OP_Function opcode that invokes "randomblob(1.5e6)"). (check-in: f3b6959c user: drh tags: trunk)
2017-03-12

01:56
The output of the ".dump" command in the CLI quotes newline and carriage-return characters using "char(10)" and "char(13)". (Closed-Leaf check-in: 8b2954dd user: drh tags: string-quoting-dump)

2017-03-09
22:00
Remove the test/dbselftest.c program. In its place, add the ".selftest" command to the CLI. The new CLI version is .selftest is slightly different in that it uses SHA3 hashing instead of SHA1, so the new is subtly incompatible with the old. (check-in: f4fcd46f user: drh tags: trunk)
18:13
Fix the ".dump" command to correctly extract tail data from corrupt WITHOUT ROWID tables. (check-in: 6c627e50 user: drh tags: trunk)
16:32
Add the --recovery-mode option to the CLI ".dump" command. This involves enhancing the "PRAGMA reverse_unordered_selects" command to accept a "TOGGLE" option. Recovery mode used to be always on. Now it is opt-in. Not sure this is the correct approach. Also not sure if TOGGLE is a good feature to have on boolean PRAGMA statements. (Closed-Leaf check-in: 5dc82a15 user: drh tags: dump-recovery)
13:50
Begin moving separate boolean variables in the ShellState object of the CLI into the shellFlgs bitmask. (check-in: 50eec5d9 user: drh tags: trunk)

In the ".sha3sum" command, if there is a LIKE pattern, show the hashes for each table separately. Without a LIKE pattern, show a single hash over the entire database. (check-in: 30f87883 user: drh tags: trunk)
16:10
Add the ".sha3sum" command to the CLI - used to compute a cryptographic hash of the content of a database file or of individual tables with in that file. (check-in: fc663799 user: drh tags: trunk)

A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85 user: drh tags: btree-moveto-neighbor)
16:54
B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page.

16:57
Fix a problem causing SQLite to return false "foreign key violation" errors when there is a partial (i.e. WHERE constrained) UNIQUE index on the parent key columns.

17:18
Within a backup operation, ensure that a read-transaction is opened on the source database before its page size is read. This ensures the page-size used to write to the backup database is the same as its actual page-size, which is important for ZipVFS databases. (check-in: 7908fc60 user: dan tags: trunk)
2016-09-01
14:03
Have "sqldiff --rbu" ignore rows with NULL values in primary key fields. RBU can't handle such rows and the documentation already says sqldiff ignores them. Because the code now uses "=" instead of "IS" to filter on primary key columns, diffs on virtual tables are faster now too. (check-in: f4ba894a user: dan tags: trunk)
09:35
If SQLITE_ENABLE_ZIPVFS is defined, journal_mode=off is configured and a savepoint or statement rollback is attempted, move the pager into the error state to prevent the transaction from being committed.

Fix the extra comments (added with -DSQLITE_ENABLE_EXPLAIN_COMMENTS) so that the sense of <, <=, >, and >= tests is correct and so that the SQLITE_STOREP2 version is shown correctly.

17:02
Add a new method to sessions - sqlite3sessions_fullchangeset() - to return a changeset that always contains values for all old.* fields. Update changebatch to use these values to more reliably detect multi-column UNIQUE constraint violations. (check-in: efa761b2 user: dan tags: changebatch)
14:42
Fix the SQLITE_USER_AUTHENTICATION login check so that the SQLITE_AUTH_USER error code correctly propagates and is not overwritten by SQLITE_ERROR. (check-in: c640489d user: drh tags: trunk)

Fix the vector BETWEEN operator so that it only evaluates the left-most vector expression once. Add support for vector comparisons in the CASE operator. (check-in: 07e69f43 user: drh tags: rowvalue)
00:48
Reinstate the mechanism in BETWEEN that avoids evaluating the first expression more than once, but fix the affinity extractor so that it works with this mechanism. The de-duplication of the first expression still does not work for vector expressions, though. (check-in: 2f39987f user: drh tags: rowvalue)

The docs promise the in "x BETWEEN y AND z" the x expression is only evaluated once. That is no longer true, and so some tests are failing. This needs to be fixed before merging to trunk. (check-in: e50d264f user: drh tags: rowvalue)

(3) The sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() routines are combined into a single sqlite3BtreePayloadFetch() routine. The result of these changes is a smaller binary and fewer CPU cycles needed to run queries. (check-in: 2d831074 user: drh tags: trunk)

20:37
Change the sqlite3BtreeKeySize() interface into sqlite3BtreeIntegerKey() and make it only work for table btrees. Change sqlite3BtreeDataSize() into sqlite3BtreePayloadSize() and make it work for all btrees. Combine sqlite3BtreeDataFetch() and sqlite3BtreeKeyFetch() into a single sqlite3BtreePayloadFetch() routine. These changes seem to make the b-tree interface more rational and they reduce both binary size and CPU usage. (check-in: bef35e18 user: drh tags: btree-refactor)

21:18
An experimental branch with code that allows virtual tables to be declared as WITHOUT ROWID tables. This might be useful for virtual tables that model external data sources that do not have a convenient way of computing a unique rowid. The current check-in almost works, but there are still serious issues. (check-in: 49638f18 user: drh tags: without-rowid-vtab)

Update the amalgamation-tarball configure script so that it can use header file "readline/readline.h" with library file "libedit". (check-in: cbf72b04 user: dan tags: trunk)
15:03
Enhance the sqlite3_load_extension() API so that the first parameter (the "db" parameter) can be NULL. An extension that is not associated with any database connection remains loaded for the life of the process. (Closed-Leaf check-in: 3a461043 user: drh tags: persistent-extensions)
14:53
Add the vfsstat.c loadable extension - a VFS shim that measures the amount of I/O, and an eponymous virtual table that is used to extract and view the measurements. (check-in: 0987487d user: drh tags: trunk)

Minor change to the walcrash4.test module so that it works when SQLITE_DEFAULT_WAL_SYNCHRONOUS is set to something other than 2. (check-in: 61e239bc user: drh tags: trunk)
16:20
Fix an obscure problem with transactions written in "PRAGMA synchronous=full" mode on systems that do not support POWERSAFE_OVERWRITE causing an xSync() call to be omitted if the last frame written by a transaction is aligned to a sector boundary. This means that if a power failure or OS crash occurs very soon after such a transaction is committed, it may be lost following system recovery. (check-in: 37de3eab user: dan tags: trunk)
00:40
Improvements to the initialization of the push-down automoton for the Lemon-generated parser. Smaller and faster. (check-in: 3b28b68e user: drh tags: trunk)

14:11
For queries with both ORDER BY and LIMIT, if the rows of the inner loop are emitted in ORDER BY order and the LIMIT has been reached, then optimize by exiting the inner loop and continuing with the next cycle of the first outer loop. (check-in: 559733b0 user: drh tags: trunk)
13:44
Set the NULLEQ flag on the sequence counter comparison in the ORDER BY LIMIT optimization, to avoid coverage complaints about not testing the NULL case. (Closed-Leaf check-in: ed1b30dc user: drh tags: orderby-limit)

Corrections to comments on the whereScanInit() interface. (check-in: ab7ab415 user: drh tags: trunk)
16:49
For DELETE operations, make sure that seeks on the main table are not deferred, since if they are and none of the indexes reference columns of the table, the seek might never occur until the OP_Delete opcode, which is too late.

Add the sqlite3rbu_vacuum() API, to create an RBU handle that can be used to rebuild a database in the same way as the VACUUM command. (check-in: bd4a6f83 user: dan tags: trunk)
16:44
If a call to sqlite3rbu_close() on an rbu handle opened by sqlite3rbu_vacuum() returns other than SQLITE_OK, delete the contents of the rbu_state table. This ensures that if an RBU vacuum operation either completes successfully or encounters an error, the next call to sqlite3rbu_vacuum() with the same parameters starts a new RBU vacuum operation.

In this way, applications can enable extension loading for the C interface without having to expose that capability to the SQL. (check-in: edb454e4 user: drh tags: load-ext-security)
2016-04-19
19:27
Updates to ensure the values of PRAGMA settings like "page_size", "auto_vacuum", "user_version" and "application_id" are not lost when a database is RBU vacuumed. (check-in: 74ffea76 user: dan tags: rbu-vacuum)
17:11
When an RBU vacuum is started on a db identified using a URI filename, pass the same URI parameters when creating the new version of the db. This ensures that RBU vacuum works with password protected databases. (check-in: ca021ba8 user: dan tags: rbu-vacuum)
16:20
Detect attempts to use rbu vacuum on a wal mode database (not allowed). And attempts to write to a database in the middle of an rbu vacuum (which prevents the vacuum from resuming). (check-in: 00b2f4b0 user: dan tags: rbu-vacuum)

The top of an index equality loop normally starts with OP_SeekGE and OP_IdxGT. This check-in adds a flag to OP_SeekGE such that it fails immediately if the key is not equal, then jumps over the OP_IdxGT, saving a call to the key comparison functions. Consider this check-in a proof-of-concept. It needs improvement before going on trunk. Some tests fail, but only because they new use fewer key comparisons than expected (which is a good thing!).

Add an initial implementation for json_remove(). (check-in: 2a826720 user: drh tags: json)

Merge in all the trunk changes from the previous year. This breaks the cursor-hint mechanism, but provides a baseline for trouble-shooting. (check-in: 82a7a61b user: drh tags: cursor-hints)
18:26
Add the sqlite3rbu_savestate() function to the rbu extension. To force rbu to save its state to disk without closing the sqlite3rbu* handle. (check-in: 851a875a user: dan tags: trunk)

Improve the usage comment on sqlite3_analyzer: show the available switches. (check-in: 783f78e3 user: drh tags: trunk)
15:29
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS. Also, the URI syntax may be used on the command line to specify the name of the database file to examine, so an alternative VFS may be requested using a URI parameter. (check-in: e3c6d4b6 user: dan tags: trunk)
15:23
Update the [showdb] program so that the database file is read directly (bypassing the SQLite VFS) only if the --raw option is specified. Otherwise, it is read using the default VFS.

2015-08-03
17:03
Add the "--uri" option to utility program "showdb". This option causes showdb to use sqlite with the SQLITE_OPEN_URI option to open the database file, instead of opening it directly using the OS open() function. (check-in: 90e34d51 user: dan tags: showdb-uri-option)
13:44
Allow a VIEW to reference undefined tables and functions when initially created. The error report is deferred until the VIEW is used. This allows views to be created before subviews and tables that the view references. (check-in: 70b57daf user: drh tags: trunk)

17:48
Remove a duplicate "typedef struct Fts5Global Fts5Global;" from fts5_main.c (duplicate is in fts5Int.h). (check-in: 54a771fe user: dan tags: trunk)

14:10
The "PRAGMA cache_size" reads the database schema, as it has done in all prior versions of SQLite. This side-effect of cache_size is undocumented, but apparently it does get used and its absence from 3.8.11 was causing problems. (check-in: 4489722a user: drh tags: branch-3.8.11)

Only allow UNLOCKED transactions to commit if none of the pages read by the transaction have been modified since it was opened. (check-in: 0b971842 user: dan tags: begin-concurrent)

New makefile target "fastfuzztest" runs the same tests as "fuzztest" but with a 100M memory size limit. This more than doubles the speed. The original unlimited "fuzztest" is still run on a "fulltest". (check-in: cfeb1b1c user: drh tags: trunk)

Code refactoring to try to shift FROM-clause subquery manifesting until after the query planner runs. Except this does not currently work because the query planner needs an estimated of the number of rows in the manifested table. Work in progress. (check-in: cabf2187 user: drh tags: view-optimization)
19:15
Add the valgrindfuzz target to unix makefile. (check-in: e62aed01 user: drh tags: trunk)

2015-06-06
20:12
Split out the bulk of the actual VDBE code generation logic from where.c into a new file, leaving behind the analysis logic. This makes the original where.c smaller and hopefully easier to edit. (check-in: faa0e420 user: drh tags: view-optimization)
19:23
Fix a comment in fts5.h. (check-in: e964b587 user: dan tags: fts5)

For FROM-clause subqueries that cannot be flattened, try to push relevant WHERE clause terms of the outer query down into the subquery in order to help the subquery run faster and/or use less memory. Call this the "WHERE-clause push-down optimization". Do not confuse this with the completely different MySQL push-down optimization. (check-in: 6df18e94 user: drh tags: trunk)
18:07
Merge latest trunk changes with this branch. (check-in: c9ffda4a user: dan tags: fts5)
