13:54
Virtual table modules with a null xCreate method act as eponymous-only modules - they cannot be used in a CREATE VIRTUAL TABLE statement. Add the series.c extension that implements a postgres-like generate_series virtual table to demonstrate this capability. (check-in: c58426db user: drh tags: table-valued-functions)
12:52

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)

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)

11:50
Fix the bm25() function so that it multiplies scores by -1 before returning them. This means better matches have a lower numerical score, so "ORDER BY rank" (not "ORDER BY rank DESC") does what you want. (check-in: 3ee7b5a9 user: dan tags: fts5)

Prevent partial indexes on the table on the left hand side of a LEFT JOIN from being incorrectly qualified by a constraint in the ON clause of the join. This relaxes the rule introduced by the previous commit (as the partial indexes on the table on the rhs of the LEFT JOIN may now be qualified by terms within the ON clause).

Make sure partial indexes are not qualified incorrectly by a constraint that is inside the ON clause of a LEFT JOIN. Fix for ticket [2326c258d02ead33]. (check-in: 491cfe9b user: drh tags: trunk)

13:17
Fix a (almost always harmless) read past the end of a memory allocation that comes about because the Expr.pTab field is checked on an EXPR_REDUCEDSIZE Expr object before checking the Expr.op field to know that the Expr.pTab field is meaningless. (check-in: e098de69 user: drh tags: trunk)
2015-01-25
20:19
The va_list argument cannot take on a NULL value and cannot be compared with NULL on some platforms (ex: ARM). So do not attempt to do so. (check-in: 1964e656 user: drh tags: trunk)
2015-01-24
19:57
Have fts5 store rowids in ascending order. Query speed is virtually the same regardless of rowid order, and ascending order makes some insert optimizations easier. (check-in: 5206ca60 user: dan tags: fts5)
12:12
In the command-line shell, make sure stderr is unbuffered so that it automatically flushes. This has always been the case already for unix and on Windows when the output is a console, but apparently was not the case on Windows when the output was a pipe. (check-in: 2a9ea9b4 user: drh tags: trunk)

02:50
Fix another instance of an incorrect value for KeyInfo.nXField on a sorting index. More changes for ticket [f97c4637102a3ae72b79]. (check-in: dc711db4 user: drh tags: branch-3.8.8)
2015-01-19
21:36
Ensure that the KeyInfo.nXField value for ephemeral tables used to implement ORDER BY or GROUP BY clauses is set correctly, so that the sqlite3VdbeFindCompare() routine can choose the correct comparison function. Add assert() statements to the high-speed comparison functions to detect cases where they are inappropriately chosen. Fix for ticket [f97c4637102a3ae72b7911].

21:10
There are asserts in place now that will prevent a recurrence of ticket [f97c4637102a3ae7]. Nevertheless, it is good to add some test cases as well. (Closed-Leaf check-in: e02959b9 user: drh tags: tkt-f97c4637)
20:59
Make sure that the KeyInfo.nXField value of ephermeral tables used for ORDER BY and GROUP BY is set correctly, so that the correct comparison function can be choosen by sqlite3VdbeFindCompare(). (check-in: c16bae5e user: drh tags: tkt-f97c4637)

19:48
An alternative way of implementing the assert() that verifies the relative values of KeyInfo.nField+KeyInfo.nXField and the number of columns in a record. This version of the assert() only fires when the high-speed comparison routines are used - which is to say it only fires when the constraint actually matters. (check-in: bf744b49 user: drh tags: tkt-f97c4637)
15:05
Enhance the command-line shell with the ability to set the SQLITE_TESTCTRL_NEVER_CORRUPT flag using: ".testctrl never_corrupt 1". (check-in: 824328f9 user: drh tags: trunk)

15:47
Makefile enhancements: (1) Rename autoconf/tea/configure.in to autoconf/tea/configure.ac so that it works with the latest versions of autoconf. (2) Add the "amalgamation-tarball" targets to Makefile.in and main.mk (renamed from "dist" in the latter case). (3) Update the README.first file in autoconf/ (4) The TOP macro in Makefile.in is now an absolute rather than a relative path. (check-in: 3bafeec9 user: drh tags: trunk)
2015-01-13
21:26
Simplify some code in rtree, to avoid confusing the optimizer in GCC on some macs: gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00). Prior to these changes, compiling with -O3 would cause incorrect code to be generated. The change to the nodeGetCell() routine is key. The other changes are merely cosmetic details discovered while bug hunting. (check-in: 882181ff user: drh tags: trunk)
17:25
Fix prefix indexes so that they work in characters, not bytes. (check-in: af8d43a4 user: dan tags: fts5)

Make use of the fdatasync() interface if the HAVE_FDATASYNC macro is true. (check-in: 694228e4 user: drh tags: trunk)
16:49
Improvements to compile-time-option hygiene. Use "#if OPTION" instead of "#ifdef OPTION" in cases where that makes sense, so that -DOPTION=0 will work. Add the "Have-Not" configuration in releasetest.tcl which disables all of the "HAVE_component" compile-time options. (check-in: 9e92a5ed user: drh tags: trunk)

2015-01-08
22:08
Omit modules from the "valgrind" permutation that fork off separate processes. Also omit selectG.test because it is timing sensitive and valgrind is too slow to get the right answer. (check-in: 662932a6 user: drh tags: trunk)
16:47
Try to fix up the "valgrindtest" target in Makefile.in so that it avoids misuse testing that can trigger false errors. (check-in: 50b5a8af user: drh tags: trunk)

01:05
In releasetest.tcl: add options --veryquick and pass-through compiler optimization settings (ex: -O0). Collect the SQLite version number from the main.test output and show it during the summary report at the end. (check-in: e7e7bc1d user: drh tags: trunk)
2015-01-07
19:38
In releasetest.tcl, always use --disable-shared together with --disable-amalgamation because mingw generates a binary that crashes and cannot be debugged using gdb if you don't. (check-in: 19982439 user: drh tags: trunk)
19:33
Add the fts5 'optimize' command. (check-in: e749be56 user: dan tags: fts5)

20:41
Tests and fixes for fts5 external content tables. (check-in: 047aaf83 user: dan tags: fts5)
20:13
Enhance "INSERT INTO ... VALUES" so that the number of rows in the VALUES clause is not limited by SQLITE_LIMIT_COMPOUND_SELECT, and so that the stack depth is constant regardless of the number of rows in VALUES. (check-in: e1c4a359 user: drh tags: trunk)
20:04
Avoid O(N*N) behavior with very long lists of VALUES. (Closed-Leaf check-in: ee30fb35 user: drh tags: many-VALUEs)
19:16
Handle compound-select statements originating from VALUES clauses as a special case that does not use recursion. (check-in: 9ce9e43a user: drh tags: many-VALUEs)
16:27
Towards getting INSERT statements to except many VALUE terms (more than the limit imposed by SQLITE_LIMIT_COMPOUND_SELECT). This check-in segfaults on a stack overflow. And it is slow. (check-in: c9d65f73 user: drh tags: many-VALUEs)
15:48
Remove some needless recursion from compound SELECT processing. (check-in: fe677d13 user: drh tags: trunk)

2015-01-01
23:02

19:53
Add the ability to specify an alternative compiler (clang instead of gcc) on the default Makefile. Use this in releasetest.tcl to implement an -fsanitize=undefined test. (check-in: c55c05fe user: drh tags: trunk)
19:11
Enhance the "lemon" executable so that it ignores -f, -W, -O, and -I command-line options. This permits most of the same options that are passed to the compiler to also be harmlessly passed to lemon, and thus simplifies makefiles. (check-in: da408d12 user: drh tags: trunk)
18:54
Fix an error in the computation of the number of hours of runtime for individual test runs in the releasetest.tcl script. (check-in: e2b0ebe2 user: drh tags: trunk)

14:06
Fix the fkey-7.1 test so that it sorts its answer and hence always gives the same answer. (check-in: 5830c557 user: drh tags: trunk)
2014-12-31
20:35
Fix to releasetest.tcl: When doing the secondary _debug runs, convert "fulltest" to just "test". (check-in: ec264bde user: drh tags: trunk)

Ensure that when a file is extended using FCNTL_SIZE_HINT the last page is allocated on disk, even if the file will only use part of it. (check-in: c7f84717 user: dan tags: trunk)
19:26
Update the threadtest3 test program so that its output summary is compatible with releasetest.tcl. In threadtest3, do not record errors that contain the string "no such table" as being fatal errors, since they happen sometimes in a race condition in stress1. (check-in: 98cb56e2 user: drh tags: trunk)
18:07
Fix problems with the "inmemory_journal" permutation. (check-in: 79693f04 user: dan tags: trunk)
14:40
If the sorter uses mmap'd temp files, ensure all pages of the temp file have been allocated before it is accessed. Otherwise, a disk-full condition might result in a SIGBUS exception. (check-in: 77664841 user: dan tags: trunk)
13:04
Make SQLITE_CONFIG_PCACHE_HDRSZ accurate (not an over-estimate) on 32-bit systems. (check-in: 340b3477 user: drh tags: trunk)
12:03
Change notify2.test to check that sqlite3_blocking_step() uses CPU more efficiently than sqlite3_step(), not that it results in greater overall throughput for any specific number of threads. (check-in: d904d293 user: dan tags: trunk)
00:57

Omit the --makefile option and replace it with --srcdir with the default computed relative to the releasetest.tcl script itself. (check-in: 7c85e831 user: drh tags: releasetest-refactor)
19:18
Fix the fts5 bm25() function so that it matches the documentation. (check-in: 1ac7a8d0 user: dan tags: fts5)

Fix the e_walauto.test script so that it works on windows. (check-in: 7d092ebb user: drh tags: trunk)
00:20
Enhanced "stress2" testing in the threadtest3.c test program. (check-in: ae43539e user: drh tags: trunk)
00:08
Make sure the sqlite3BtreeCount() routine does not leave index cursors in an inconsistent state, as doing so might result in an assertion fault inside of sqlite3BtreeKey() called from saveAllCursors() if content is deleted out from under the statement that issued the sqlite3BtreeCount() call. (check-in: 5b1b6970 user: drh tags: trunk)
2014-12-15
20:49
Changes to threadtest3 so that "stress2" is more similar to the SDS stress test. (Closed-Leaf check-in: 5648af96 user: dan tags: threadtest3)

00:52
Remove the KeyInfo cache (for now - perhaps we will add it back in later - or maybe not since it provides negligible benefit but adds a lot of complexity and thread-safety risk). Add a mutex to ATTACH to deal with a data race. (check-in: 03c443ea user: drh tags: trunk)
00:40
Make sure the Btree mutex is held when setting the locking mode and the secure delete flag when attaching a shared-cache database. (Closed-Leaf check-in: 6bef7ede user: drh tags: threadtest4)

Merge the cell overflow page number cache thread race fix from trunk. (check-in: cefad47e user: drh tags: threadtest4)
00:20
Fix a bug in the threadtest4.c program. Remove the keyinfo cache as it provides minimal performance improvements, and then only at SQL preparation time, not at runtime, and it has problems with data races in shared-cache mode. We might later add the keyinfo cache back but only enable it when shared-cache mode is off. (check-in: b7489f94 user: drh tags: threadtest4)

22:24
Fix the sqlite3_table_column_metadata() routine so that it gives the correct answer for the "rowid" column in a WITHOUT ROWID table. Enhance it so that it can be used to check for the existence of a table by setting the column name parameter to NULL. The routine is now included in the build by default, even without the SQLITE_ENABLE_COLUMN_METADATA compile-time option. (check-in: cf9be419 user: drh tags: trunk)

19:07
Make the sqlite3_table_column_metadata() interface available by default and without requiring the SQLITE_ENABLE_COLUMN_METADATA compile-time option. Other sqlite3_column_* interfaces that have a run-time penalty even if they are unused still require the SQLITE_ENABLE_COLUMN_METADATA option at compile-time. (check-in: 4f7549ff user: drh tags: trunk)
15:12
Add the SQLITE_REVERSE_UNORDERED_SELECTS compile-time option that causes the "PRAGMA reverse_unordered_selects" setting to be on by default. (check-in: 75a803e6 user: drh tags: trunk)

Remove the ill-designed "-end" option from the command-line shell. Instead, allow multiple SQL or dot-commands as command-line arguments. Any -cmd commands are processed first, followed by other command-line arguments, for backwards compatibility. (check-in: 24fa2e98 user: drh tags: trunk)
11:54
Add the -end option to the command-line shell, which forces it to exit after reading prior command-line options (presumably including one or more -cmd options) and without reading standard input. (check-in: b59397b1 user: drh tags: trunk)

13:13
Enhance whereLoopCheaperProperSubset(X,Y) so that it does not report true if X uses skip-scan less than Y, since in that case X might deserve to be cheaper even if it is a proper subset. (check-in: c106b755 user: drh tags: trunk)
09:07
Add the ".scanstats on" command to the shell tool. Executing this command causes the shell tool to print values from sqlite3_stmt_scanstatus() after each query is run. (check-in: 7974c0ed user: dan tags: trunk)

14:46
Use exponential buffer size growth in StrAccum, as long as the size does not grow to large, to avoid excess memory allocation resize operations. Also, document the fact that setting scratch memory causes SQLite to try to avoid large memory allocations. (check-in: a518bc33 user: drh tags: trunk)
13:24
When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to record the entire size of the allocation, not just the requested size. (check-in: 3dda3c93 user: drh tags: trunk)

01:13
In the OP_Column opcode, when extracting a field that is past the end of a short record (because the row was originally inserted prior to ALTER TABLE ADD COLUMN) then make sure the output register is fully NULL and does not contain leftover flags (such as MEM_Ephem) from its previous use. Fix for ticket [43107840f1c02]. This is a cherrypick of check-in [24780f8ddc1683fc]. (check-in: 304ea6ba user: drh tags: branch-3.8.7)
01:07
Call fsync() right after ftruncate() when in journal_mode=TRUNCATE and when synchronous=FULL in order to ensure that transactions are durable across a power loss that happens moments after the commit.

01:05
If a skip-scan is a proper subset of some other scan, then adjust the cost of the skip-scan upward so that it is more costly than the other scan. Such a cost imbalance can arise under STAT4 because of difficulties in getting an accurate estimate for skip-scans. (check-in: f4b22a26 user: drh tags: trunk)

Optimize a database corruption test inside of the OP_Column opcode. (check-in: 005e5b38 user: drh tags: trunk)
20:12
Use the padding word in the Mem object as temporary storage for serial_type value in OP_Record, and thus avoid a redundant computation of the serial_type for each column. (check-in: 4b3b65ee user: drh tags: trunk)
18:09

16:02
Reduce the CPU load imposed by sqlit3VdbeCursorMoveto() by factoring out some of its functions and by avoiding unnecessary calls. (check-in: c2799aec user: drh tags: trunk)
13:00
Remove the OPFLAG_CLEARCACHE flag from OP_Column. In its place, change the P3 parameter of OP_SorterData to be the index of the pseudo-table cursor whose record header cache is to be cleared. This gives a small size reduction and performance increase. (check-in: 20062f49 user: drh tags: trunk)
2014-10-12
22:37
Remove the VdbeCursor.lastRowid cache of the current rowid, since maintaining the correct cache value uses more CPU cycles than just recomputing the rowid on the occasions when it is actually needed. Replace it with the VdbeCursor.aOffset field which used to be computed from VdbeCursor.aType when needed. Saves 100 bytes of code space and runs 0.2% faster. (check-in: 91384a7d user: drh tags: trunk)

23:31
Performance optimization and very slight size reduction for OP_Column. (check-in: 869c30e4 user: drh tags: trunk)

Attempt to further reduce memcpy() in balance_nonroot(). (check-in: fec849dc user: dan tags: defrag-opt)
17:22
Simplification to the insertCell() routine in btree.c, resulting in a performance boost and a very small size decrease. It turns out that the extra work involved in sometimes avoiding an memcpy() of the first four bytes of a record takes more time than just unconditionally copying those four bytes. (check-in: 66de1558 user: drh tags: trunk)

00:07
Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside. (check-in: efd87ba1 user: drh tags: stat4-avgeq)

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 tags: trunk)

Add the sqlite3_msize() interface. Internal memory allocation routines now use 64-bit unsigned length parameters for safety. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 7e4978c0 user: drh tags: trunk)
17:27
Add the SQLITE_USER_AUTHENTICATION extension to the trunk. This extension is disabled by default. Special compilation procedures are need to enable it. (check-in: 65884d4f user: drh tags: trunk)

18:41
Add new interfaces to the loadable extension mechanism. (check-in: 18d80cbc user: drh tags: 64-bit-lengths)
17:27
Add new APIs that take 64-bit length parameters: sqlite3_malloc64(), sqlite3_realloc64(), sqlite3_bind_blob64(), sqlite3_bind_texte64(), sqlite3_result_blob64(), and sqlite3_result_texte64(). Internal memory allocation routines also now use 64-bit unsigned length parameters for safety. Also add the sqlite3_msize() interface. Fix the sqlite3_get_table() to use sqlite3_realloc64() to avoid a integer overflow problem. (check-in: 94954850 user: drh tags: 64-bit-lengths)

03:16
Add the sqlite3_memdebug_title_count global variable, used during debugging to count the number of invocations of test_memdebug_settitle. By examining this variable in the debugger after a segfault, one can then set a breakpoint on test_memdebug_settitle that will fire just before the problem. (check-in: 27e3ca3e user: drh tags: trunk)
02:00

14:14
In the sqlite3_context object, keep a pointer to the result value rather than storing the result value in the sqlite3_context object and using memcpy() to move the value back into its register after the function returns.

Performance enhancement in sqlite3VdbeMemNulTerminate(). (check-in: f94cacc3 user: drh tags: trunk)
2014-08-26
15:06
Change the page cache so that a new sqlite3_pcache object is allocated as soon as the page cache is opened, not delayed until the first fetch request. This give a noticable performance boost. The interface between pager and the page cache has changed slightly, which might break ZIPVFS. (check-in: f1f94a97 user: drh tags: trunk)
2014-08-25
23:44
Remove the SQLITE_CONFIG_WORKER_THREADS configuration parameter. The number of worker threads in the sorter is now determined only by the PRAGMA threads=N setting. (check-in: e3305d4b user: drh tags: threads)

20:11
Allow CAST expressions and unary "+" operators to be used in the DEFAULT argument of an ALTER TABLE ADD COLUMN and to be understand on the RHS of range constraints interpreted by STAT3/4. This involves a rewrite of the implementation of the CAST operator. (check-in: 91d8a8d0 user: drh tags: trunk)
19:58
Add documentation for tokenizer api to fts5.h. Also add a script to extract extension API docs and format them as html. (check-in: e240d467 user: dan tags: fts5)
18:29
In cases where stat4 data is available but cannot be used because the rhs of a range constraint is too complex a expression, fall back to using the default estimates for number of rows scanned. (check-in: e06dc6f0 user: dan tags: trunk)
15:13
Query or change the maximum number of worker threads allowed on each database connection separately using the "PRAGMA threads" command. (check-in: 29c5e8a7 user: drh tags: threads)

Merge the recent performance enhancements implemented on trunk into the threads branch. (check-in: dfdc900f user: drh tags: threads)
11:33
Remove the pager_lookup() function since it is redundant with sqlite3PagerLookup(). (check-in: 54164ce4 user: drh tags: trunk)
11:20
Change the name of the VdbeMemRelease() macro to VdbeMemReleaseExtern() to more accurately reflect what it does. Performance enhancement to the sqlite3VdbeMemRelease() function. (check-in: 3ca5846d user: drh tags: trunk)

2014-08-22
23:33
Another performance tweak: Split the sqlite3BtreeCursorHasMoved() routine into two with the second routine named sqlite3BtreeCursorRestore(). The first now only reports whether or not the cursor has moved and the second tries to restore the cursor. This allows the sqlite3VdbeCursorMoveto() routine to be refactored to avoid stack pointer movements, for a noticable performance gain. (check-in: ce123b5c user: drh tags: trunk)
22:26

Improvements to the way the query planner handles sorting costs, so that very large sorting costs do not overwhelm the loop costs. (check-in: bdaa6947 user: drh tags: trunk)
17:25
Fix a buffer overrun in the previous commit. (Closed-Leaf check-in: 43c59c85 user: dan tags: query-planner-fix)
16:52
Because SQLite internally calculates query plan costs using a logarithmic scale, very large estimated sorting costs can cause all other estimated costs to be rounded down to zero. In these cases break ties between plans with the same total cost by comparing the costs with sorting excluded. This is an alternative fix for the problem addressed by [2af630c572]. (check-in: 299b9570 user: dan tags: query-planner-fix)
15:38
The SQLITE_IOERR_BLOCKED extended error code is not longer used, so remove assert() statements and documentation for that error code. Also make other documentation improvements. (check-in: 36b7c5ce user: drh tags: trunk)

Remove the extraneous debugging printf() from the previous check-in. (check-in: 8f04d2c0 user: drh tags: query-planner-fix)
18:47
Add "segment promotion" to fts5. This prevents the FTS index from growing indefinitely as data is added and deleted. (check-in: ba359d78 user: dan tags: fts5)
16:50
Oops! This check-in was on trunk. But it contains a debugging printf(). Original comment: When the estimated cost to do a sort overwhelms the estimated cost to do individual table lookups, make sure that the table lookup costs are still taken into consideration when selecting the lookup algorithm. (check-in: ec5d84ba user: drh tags: query-planner-fix)

00:29
A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. (check-in: 0ad1ed8e user: drh tags: trunk)
2014-08-05
21:31
Ensure that aggregate functions are not used when evaluating a default value for a table column. Candidate fix for ticket [3a88d85f36704eebe134f7]. (check-in: 29ba8128 user: drh tags: trunk)

Use doclist indexes for AND queries as well as phrases. (check-in: 5d38e6ed user: dan tags: fts5)
19:16
Add the ability to evaluate IN operators as a sequence of comparisons as an alternative to the long-standing algorithm of building a lookup table. Use the new implementation in circumstances where it is likely to be faster, such as when the RHS of the IN changes between successive evaluations. (check-in: 95286821 user: drh tags: trunk)

2014-08-02
21:03
Enhancements to the code generator for the IN operator that result in much faster queries in some cases, for example when the RHS of the IN operator changes for each row of a large table scan. (check-in: 436e8842 user: drh tags: IN-operator-improvements)
20:49
Start changing things to use doclist indexes as required. code is not activated yet. (check-in: b8864da9 user: dan tags: fts5)

19:27
Have the fts5 integrity-check verify that doclist indexes match the contents of the leaf pages that they index. (check-in: 37a7d303 user: dan tags: fts5)
18:00
Remove an unnecessary OP_Null in the IN-operator logic. Attempt to clarify comments explaining the IN-operator code, though it is not clear that the comments are correct even yet - more work to be done. (check-in: c11e55fa user: drh tags: trunk)
15:51
Clean up the IN operator code generation logic to make it easier to reason about. In the process, improve code generation to omit some unused OP_Null operations. (check-in: 7c6fbcfe user: drh tags: trunk)
15:34
The idea of coding IN operator with a short list on the RHS as an OR expression turns out to be helpful. If the list is of length 1 or 2, the OR expression is very slightly faster, but the ephemeral table approach is clearly better for all list lengths greater than 2. Better to keep the code simple. (Closed-Leaf check-in: e13175d3 user: drh tags: IN-operator-improvements)
14:46
Begin making changes to the IN operator in an attempt to make it run faster and to make the code easier to understand. (check-in: ee0fd6aa user: drh tags: IN-operator-improvements)
11:16
Add "doclist index" records to the database. These are to make navigating within very large doclists faster. They are not yet used by queries. (check-in: 89377421 user: dan tags: fts5)

Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. (check-in: 729ece40 user: drh tags: trunk)
19:37
Ugh. Consecutive UNIQUE index entries are only distinct if the index is on NOT NULL columns. So the previous version was not quite right. This check-in fixes the problem. (check-in: 30033f96 user: drh tags: faster-analyze)
19:31
Add a snippet() function to fts5. (check-in: bdc58fd2 user: dan tags: fts5)

Remove a surplus function prototype. #ifdef code that is not used when hex integers are omitted at compile time. (check-in: a5b383e0 user: drh tags: hex-literal)
13:40
Change the hex literal processing so that only the SQL parser understands hex literals. Casting and coercing string literals into numeric values does not understand hexadecimal integers. This preserves backwards compatibility. Also: Throw an error on any hex literal that is too big to fit into 64 bits. (check-in: 6c6f0de5 user: drh tags: hex-literal)
02:07
Casting hex literals directly from string to float always results in a positive number. (check-in: 4b86ccdf user: drh tags: hex-literal)

12:03
In the command-line shell, if three or more interrupt signals (control-c) are received in a row without a response from sqlite3_interrupt() then call exit(1) immediately. This allows control-C to interrupt the shell even if it is stuck in a computation or loop that does not involve the VDBE. (check-in: b5cde571 user: drh tags: trunk)

Fixes to prevent an FTS index from growing indefinitely as the corresponding table is updated. Change the FTS 'automerge' option to allow the user to specify the number of segments that should be merged simultaneously by auto-merges. (check-in: a75f1800 user: dan tags: trunk)
15:48
Add extra test to backcompat.test to ensure that old and new versions of FTS may work together on the same incremental merge operation. (Closed-Leaf check-in: 3997d47b user: dan tags: fts4-experimental)

18:21
Ensure that the sqlite3StrAccumAppend() routine is never called with a NULL second argument. Doing so is harmless when N==0, but it causes an assert() to fail that was placed to quiet static analyzers. (Closed-Leaf check-in: f03fbf37 user: drh tags: tkt-55746f9e)
