19:27
Fix some duplicated test names. (check-in: 1797158db2 user: mistachkin tags: trunk)
19:12
Ensure that "PRAGMA wal_checkpoint = TRUNCATE|FULL|RESTART" block on other connections and truncate the wal file as required even if the entire wal file has already been checkpointed. (check-in: 53429689d4 user: dan tags: trunk)
18:38
Split up the SRC variable in Makefile.msc to avoid over-long cmd.exe commands when TOP is set to a long pathname. (check-in: 7d70ac65c1 user: drh tags: trunk)
17:54
Add the INITMODE test-control. (check-in: 5940af8e78 user: drh tags: initmode-testctrl)
15:53
Improvements to the DELETE code generator for the one-pass case. Avoid some OP_Goto instructions. Read content from the index cursor if the index cursor is valid and was used to locate the row that is to be deleted. (Closed-Leaf check-in: 58cc257aeb user: drh tags: one-writable-btree)
14:48
Avoid overlength command lines in Makefile.msc when using TOP= with a large directory name. (check-in: 0cdd59bf36 user: drh tags: one-writable-btree)
11:52
Optimize range constraints on the rowid column of fts3/4 tables even if there is no MATCH clause in the query. (check-in: 85dc12625d user: dan tags: trunk)
02:26
Experimental sqlite_db_config() setting to disable writing to all btrees except for one btree with a particular root page. (check-in: 2305411097 user: drh tags: one-writable-btree)
2015-01-28
20:37
Add missing VdbeCoverage() macros to the sqlite3_index_writer() implementation. (check-in: 6f8cda26e9 user: drh tags: ota-update)
15:30
When a "full", "restart" or "truncate" checkpoint is attempted, return SQLITE_BUSY if a reader prevents the checkpointer from copying any frames at all into the database file. (check-in: f270004016 user: dan tags: ota-update)
12:27
Correctly detect errors returned by walCheckpointStart() due to OOM. (check-in: 8e878c2023 user: drh tags: ota-update)
12:00
Merge in all changes from trunk. (check-in: 17c69be805 user: drh tags: ota-update)
2015-01-27
21:24
Fix harmless compiler warnings. (check-in: e7d2ec048c user: mistachkin tags: trunk)
20:41
Fix a problem with fts5 doclist-indexes that occured if the first rowid of the first non-term page of a doclist is zero. (check-in: f704bc059e user: dan tags: fts5)
19:01
Fix a bug in the fts3 snippet() function causing it to omit leading separator characters from snippets that begin with the first token in a column. (check-in: adc9283dd9 user: dan tags: trunk)
18:43
Improve the performance of fts3/4 queries that use the OR operator and at least one auxiliary fts function. (check-in: 245e873045 user: dan 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: e098de6910 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: 1964e656b4 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: 5206ca6005 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: 2a9ea9b4a7 user: drh tags: trunk)
2015-01-23
17:43
Fix compression of keys stored on internal segment b-tree nodes by fts5. (check-in: 51444f67c0 user: dan tags: fts5)
06:50
Remove some redundant code from fts5. (check-in: 939b7a5de2 user: dan tags: fts5)
2015-01-22
19:13
Add further tests and fixes for fts5. (check-in: 5b29589715 user: dan tags: fts5)
12:00
Make sure errors in the FROM clause of a SELECT cause analysis to abort and unwind the stack before those errors have a chance to mischief in the "*" column-name wildcard expander. Fix for ticket [32b63d542433ca67]. (check-in: 9e6eae660a user: drh tags: trunk)
11:29
Change the undocumented ".selecttrace" command in the shell to accept an integer bitmask rather than a boolean. (check-in: bd63bf882c user: drh tags: trunk)
2015-01-21
20:30
Further tests and fixes for fts5. (check-in: c020a291ed user: dan tags: fts5)
18:23

17:20
Merge trunk changes with this branch. (check-in: f8699a1a3b user: dan tags: fts5)
17:00
Fix an assert() that may fail following an OOM error. (check-in: 5f592359d6 user: dan tags: trunk)
16:10
Add further tests for fts5 backend. (check-in: 09dabb3b9e user: dan tags: fts5)
06:36
Merge latest trunk changes with this branch. (check-in: b3348b1e07 user: dan tags: fts5)
00:51
Fix harmless compiler warning seen with MSVC. (check-in: 78c2e62bb4 user: mistachkin tags: trunk)
00:48
Enhancements to entropy generation for the Win32 VFS. (check-in: 26190b3c63 user: mistachkin tags: trunk)
2015-01-20
16:51
Version 3.8.8.1 (check-in: f73337e3e2 user: drh tags: release, version-3.8.8.1, branch-3.8.8)
03:04
Fix another instance of an incorrect value for KeyInfo.nXField on a sorting index. Ticket [f97c4637102a3ae72b79]. (check-in: 0077f64510 user: drh tags: trunk)
02:51
Change the version number to 3.8.8.1 (check-in: c75555a354 user: drh tags: branch-3.8.8)
02:50
Fix another instance of an incorrect value for KeyInfo.nXField on a sorting index. More changes for ticket [f97c4637102a3ae72b79]. (check-in: dc711db44e user: drh tags: branch-3.8.8)
2015-01-19
21:38
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]. (check-in: 59e592f67f user: drh tags: branch-3.8.8)
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]. (check-in: f7201bb0cd user: drh tags: trunk)
21:27
Improve precision of the new test case by removing a superfluous carriage-return from the shell command input. (check-in: 913c41b2cd user: mistachkin tags: expShell)
21:11
Add comments and improve the new test case. (check-in: 4ec2aeadf9 user: mistachkin tags: expShell)
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: e02959b9a0 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: c16bae5e69 user: drh tags: tkt-f97c4637)
20:57
Fix the assert() of the previous check-in so that it works even when compiled without SQLITE_DEBUG. (check-in: 38868f845e user: drh tags: tkt-f97c4637)
20:22
Remove a shell function that is now superfluous. (check-in: d8564f70e6 user: mistachkin tags: expShell)
20:19
Merge updates from trunk. (check-in: d9f4035b38 user: mistachkin tags: expShell)
20:05
Fix compilation on Cygwin when SQLITE_MAX_WORKER_THREADS is greater than zero. (check-in: 2037442c58 user: mistachkin tags: trunk)
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: bf744b4908 user: drh tags: tkt-f97c4637)
19:21
An alternative way of fixing the key comparison bug of ticket [f97c4637102a3ae72b]. (Closed-Leaf check-in: e41376cf08 user: drh tags: alt1-tkt-f97c4637)
18:18
Strengthen the KeyInfo number-of-columns assert() added by the previous check-in. (Closed-Leaf check-in: d0971b7913 user: drh tags: tkt-f97c4637)
17:28
Add an assert() to verify that the nField+nXField values of a KeyInfo object are never less then the number of columns in a row for a non-corrupt database. This assert() currently fails, which is the root of the problem with ticket [f97c4637102a3ae72b]. (check-in: 083f523d2f 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: 824328f983 user: drh tags: trunk)
07:42
Merge updates from trunk. (check-in: c7167f88ec user: mistachkin tags: expShell)

2015-01-18
20:30
Set binary mode for output on Windows when writing a quoted string that might contain newline characters. (check-in: 7096e6c06d user: drh tags: trunk)

Modify the new shell test case to work on non-Windows platforms as well. (check-in: f362c5d9d1 user: mistachkin tags: expShell)
05:35
Some experimental command line shell input/output enhancements. (check-in: 25e99f3fe5 user: mistachkin tags: expShell)
01:50
Set the command-line shell stdin to binary mode on windows. (check-in: 80541e8b94 user: drh tags: trunk)
2015-01-17
15:26
Fix a harmless compiler warning the VFS for Windows. (check-in: ceac571f53 user: drh tags: trunk)
2015-01-16
19:35
Fix harmless compiler warning. (Closed-Leaf check-in: cab46fb737 user: mistachkin tags: msvcWarn)
12:44
Merge all 3.8.8 changes into the sessions branch. (check-in: bebd131a35 user: drh tags: sessions)
12:24
Merge the 3.8.8 release changes from trunk. (check-in: 518621f8dc user: drh tags: apple-osx)
12:08
Version 3.8.8 (check-in: 7d68a42fac user: drh tags: trunk, release, version-3.8.8)
2015-01-15
17:38
Fix the spelling of "malloc_usable_size" in configure and configure.ac. (check-in: 8f45217cba 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: 3bafeec934 user: drh tags: trunk)
2015-01-14
17:16
Merge trunk 3.8.8 beta changes into the sessions branch (check-in: 0ba124540b user: drh tags: sessions)
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: 882181ff9d user: drh tags: trunk)
01:12
Fix the e_walauto.test test module so that it works on both little-endian and big-ending machines. (check-in: 5682db7b87 user: drh tags: trunk)

Add an assert() in order to calm a scan-build warning. (check-in: 11e81ac2a7 user: drh tags: trunk)
2015-01-10
18:22
Add detection of the isnan() library function to the configure script. Make the code responsive to the HAVE_ISNAN configuration option. (check-in: 46f3aba269 user: drh tags: trunk)
18:02
Make use of the fdatasync() interface if the HAVE_FDATASYNC macro is true. (check-in: 694228e463 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: 9e92a5ed5a user: drh tags: trunk)
15:21
Add the ability to put comments in the Config and Platform setup sections of the releasetest.tcl script. (check-in: d6f8c899d8 user: drh tags: trunk)
14:27
Autoconf configure script updates: (1) remove the long-obsolete --enable-cross-thread-connections option. (2) remove the --with-hints= options. (3) Extension loading is enabled by default. (4) Check for strchrnull() (5) Update the --help text. (check-in: 5004063ce4 user: drh tags: trunk)
2015-01-09
21:54
Change the testfixture binary so that it explicitly enabled core files on a crash (on unix). Add a test case to verify that this works. (check-in: 90f422ed81 user: drh tags: trunk)
20:00
Add SQLITE_ENABLE_STMT_SCANSTATUS to the Update-Delete-Limit configuration in the releasetest.tcl script. (check-in: c70d5edaf6 user: drh tags: trunk)

22:51
Correct help text and make consistent use of snprintf. (check-in: 9c424a5c50 user: mistachkin tags: asciiMode)
22:33
Update a shell test case. (check-in: b84008cb96 user: mistachkin tags: asciiMode)

Merge updates from trunk. (check-in: 8dc0cdf652 user: mistachkin tags: asciiMode)
12:39
Add the readfile(FILENAME) and writefile(FILENAME,CONTENT) SQL functions to the command-line shell. (check-in: fb1048cb2b user: drh tags: trunk)
12:19
Add support for hexadecimal integer literals in the parser. (check-in: f8f79f2878 user: drh tags: trunk)
12:09
In the command-line shell, in CSV output mode, terminate rows with CRNL but do not expand NL characters in data into CRNL. Provide the extra -newline command-line option and the extra argument to .separator to designate an alternative newline character sequence for CSV output. (check-in: 16c8ce10e1 user: drh tags: trunk)
2014-07-23
23:57
Add experimental "costmult" logic. Only enabled when compiled with -DSQLITE_ENABLE_COSTMULT. (check-in: 729ece4088 user: drh tags: trunk)
19:04
Enhancements to the hex literal tests. (Closed-Leaf check-in: a3cc027fa7 user: mistachkin tags: hex-literal)
15:51
Updated documentation on sqlite3_temp_directory. No changes to code. (check-in: e6225a7bf7 user: drh tags: trunk)
14:52
Remove a surplus function prototype. #ifdef code that is not used when hex integers are omitted at compile time. (check-in: a5b383e077 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: 6c6f0de59b user: drh tags: hex-literal)
02:07
Casting hex literals directly from string to float always results in a positive number. (check-in: 4b86ccdf4f user: drh tags: hex-literal)
01:59
Reformatting a few test cases for clarity. (check-in: 7e1bbacb11 user: drh tags: hex-literal)
01:56
Test cases for hex literals. (check-in: 19054339c4 user: drh tags: hex-literal)
01:26
Add support for parsing C-style hexadecimal literals. (check-in: 34a1f38b7a user: drh tags: hex-literal)
2014-07-22
22:46
When running ANALYZE, it is not necessary to check the right-most key column for changes since that column will always change if none of the previous columns have. (check-in: 48f40861db user: drh tags: trunk)
20:02
Add the OP_ReopenIdx opcode that works like OP_OpenRead except that it becomes a no-op if the cursor is already open on the same index. Update the OR-optimization logic to make use of OP_ReopenIdx in order to avoid unnecessary cursor open requests sent to the B-Tree layer. (check-in: 77f412caf0 user: drh tags: trunk)
19:14
The optimization of check-in [b67a6e33f2] does not work (it generates incorrect VDBE code) if an OR term is AND-ed with a constant expression. So back that optimization out and add a test case to make sure it does not get added back in. (check-in: eed754fe93 user: drh tags: trunk)
16:00
Fix the index name for the shadow tables in the spellfix1 extension so that multiple instances of the spellfix1 virtual table can each have their own index. (check-in: 438c348a40 user: drh tags: trunk)
15:33
Correction: The maximum SQLITE_MAX_ATTACHED value to avoid overflowing a signed 8-bit integer is 125, not 127. (check-in: 48e3780295 user: drh tags: trunk)
14:58
Enhance the sqlite_stat1.stat parsing to allow additional text parameters at the end. Unrecognized parameters are silently ignored. (check-in: ca2a5a2c77 user: drh tags: trunk)
14:42
Expire prepared statements after running ANALYZE. (check-in: b083a961f8 user: drh tags: trunk)
12:05
Enhance the comment on whereLoopAddBtree(). No changes to code. (check-in: b22dd165da user: drh tags: trunk)
00:40
For the OR-optimization, avoid generating OP_OpenRead opcodes that reopen exactly the same index. (check-in: b67a6e33f2 user: drh tags: trunk)
2014-07-21
20:07
Limit the maximum SQLITE_MAX_ATTACHED to 127, since a signed character is sometimes used to store the database index. (check-in: f1c76c7c4c user: drh tags: trunk)
15:44
Allow the SQLITE_MAX_ATTACHED compile-time option to be larger than 62. The default limit on the number of attached databases remains 10. (check-in: 1a817ae2f3 user: drh tags: trunk)
2014-07-19
20:15
