20:48 | Merge multiple changes from trunk to address concerns with window-function parse-tree rewriting. (check-in: 05418b2a4a user: drh tags: branch-3.32-early-winfunc-rewrite) | |
19:54 | Fix a possible ASAN violation inside of debug-only code following an OOM. (check-in: 0e021887a1 user: drh tags: early-winfunc-rewrite-dev) | |
19:35 | When determining if the subquery inserted by the window-function rewriter is an aggregate query, aggregate functions that are in parameters to another window function do not count. Fix for ticket [1f6f353b684fc708] (check-in: 8583c3483c user: drh tags: early-winfunc-rewrite-dev) | |
18:45 | Clearly distinguish between window functions and scalar functions in the debugging TreeView output. (check-in: 15babdcb91 user: drh tags: early-winfunc-rewrite-dev) | |
18:34 | In the query flattener, defer deleting content until after associated Parse object is destroyed, in case some of the deleted expressions have been collected for use by sAggInfo. (check-in: 03b32be44d user: drh tags: early-winfunc-rewrite-dev) | |
14:58 | Remove an incorrect assert() added earlier today. (check-in: 3926ff1725 user: drh tags: early-winfunc-rewrite-dev) | |
14:44 | When rewriting the parse-tree for window functions, ensure that the inserted subqueries have an accurate SF_Aggregate bit set. This change also coincidentally fixes ticket [0899cf62f597d7e7], even thought that was not the issue we were working on at the time. (check-in: 2cddb24e91 user: drh tags: early-winfunc-rewrite-dev) | |
14:29 | Fix an assert() failure that could occur if an ORDER BY expression attached to a compound query contains a subquery that (a) is itself a compound query, (b) uses window functions and (c) has an ORDER BY clause that includes another sub-query. (check-in: c96914ea02 user: dan tags: early-winfunc-rewrite-dev) | |
13:29 | Avoid no-op calls to sqlite3SelectPrep() when processing sqlite3Select() for subqueries. This simplifies the ".selecttrace" debugging output. (check-in: 3de19ee22a user: drh tags: early-winfunc-rewrite-dev) | |

21:36 | Improved tracing of window function parse tree rewrites. (check-in: 7e8060cf96 user: drh tags: early-winfunc-rewrite-dev) | |
18:17 | Assign a fake name to the ephemeral subquery tables that are created when making parse-tree changes for window functions. (check-in: c4072267dc user: drh tags: early-winfunc-rewrite-dev) | |
15:56 | Do parse-tree transformations required for window functions prior to running aggregate function analysis. Fix for ticket [c8d3b9f0a750a529]. (check-in: 79eff1d038 user: drh tags: branch-3.32-early-winfunc-rewrite) | |
15:40 | New test case for fuzzdata8.db. (check-in: 2870d11720 user: drh tags: early-winfunc-rewrite-dev) | |
15:26 | Do parse-tree transformations required for window functions prior to running aggregate function analysis. Fix for ticket [c8d3b9f0a750a529]. (check-in: 0b42a2277e user: drh tags: early-winfunc-rewrite-dev) | |
14:53 | Ensure that the "push-down" optimization does not push constraints down into compound queries if any of the component queries uses window functions. (Closed-Leaf check-in: 2011e83213 user: dan tags: early-winfunc-rewrite) | |
14:25 | ALWAYS() and NEVER() macros added due to unreachable branches arising from the previous check-in. (check-in: 13ffedab9b user: drh tags: early-winfunc-rewrite) | |
14:10 | Move the parse tree rewrite for window functions earlier in the process, before sqlite3ExprAnalyzeAggregates() has run. Add new assert()s to verify that aggregate analysis always remains valid until the end of SELECT processing. (check-in: fe702aa08c user: drh tags: early-winfunc-rewrite) | |
04:01 | In the debugging treeview output, change the name of "SELECT-expr" expression nodes to be "subquery-expr", so as to not confuse them with actual SELECT nodes. (check-in: c1c8937a30 user: drh tags: trunk) | |
00:54 | Always use ?...? to indicate optional arguments in the output of ".help" in the CLI. Change ".mode column" so that it automatically activates ".headers on" if headers have not been previously turned on or off. (check-in: 2827c0a186 user: drh tags: trunk) | |
2020-06-04
| ||
18:05 | Add support for "box" mode in the CLI: Like "table" except that it uses unicode box-drawing characters instead of ascii-art. (check-in: 6da784c9e1 user: drh tags: trunk) | |
16:54 | Improved display of ".mode table" output for empty result sets. (check-in: 7efabd683b user: drh tags: trunk) | |
16:34 | Use __has_extension(c_atomic) instead of __has_feature(c_atomic) to detect support for atomic load and store operations with clang. (check-in: 362255791f user: dan tags: trunk) | |
16:07 | Use AtomicStore() to set values in the wal-index hash table. (check-in: 1ab30c75f2 user: dan tags: trunk) | |
12:58 | Version 3.32.2 (check-in: ec02243ea6 user: drh tags: release, branch-3.32, version-3.32.2) | |
02:50 | Work around a bug in clang-11.0.0. See forum post 3c2bf8042ec46195 for further info. (check-in: 3c2bf8042e user: drh tags: trunk) | |

22:47 | Version number to 3.32.2 (check-in: 4454b27fc5 user: drh tags: branch-3.32) | |
19:28 | Fix for ticket [810dc8038872e212]. Thank to user "Maxulite" for tracking down the problem! (check-in: 89af93d77f user: drh tags: trunk) | |
15:59 | Simplification to the interrupt handling logic in sqlite3VdbeExec() saves a few bytes of code space. (check-in: 43e0e59bd4 user: drh tags: trunk) | |
03:00 | Improve the query planner so that it is better able to find full index scan plan when there is an INDEXED BY clause. (check-in: d901837fea user: drh tags: trunk) | |
2020-05-30
| ||
15:34 | Draw the dashes below the headers in "explain" mode in the CLI. (check-in: c6b7833ac7 user: drh tags: trunk) | |
00:30 | Improved VDBE comments on the ANALYZE code generator. This change also fixes a harmless use of an uninitialized integer variable as an input to the %d format on a VDBE comment. (check-in: 1cb248a3fc user: drh tags: trunk) | |
2020-05-29
| ||
21:06 | Enhancements to the incremental build support for MSVC. (check-in: 2e25d915bc user: mistachkin tags: trunk) | |
20:16 | Remove a stray "&" character in the CLI, detected by a clang warning. (check-in: 5865d2f2d0 user: drh tags: trunk) | |
19:45 | Add the "shelltest" target to the MSVC makefile as well. (check-in: 9924c0456b user: drh tags: trunk) | |
19:39 | Fix the ".import" command of the CLI to clean up better after errors. Add the new "shelltest" makefile target on unix platforms. (check-in: 50d4ddf133 user: drh tags: trunk) | |
19:17 | Improvements to help text for the CLI. (check-in: 6a01e4c444 user: drh tags: trunk) | |
19:03 | Fix a memory leak in the CLI when an unknown or unrecognized argument is given to the ".dump" command. (check-in: 71bfbbcc1a user: drh tags: trunk) | |
16:15 | Improvements to columnar output in the CLI. Columns automatically expand to contain the largest row. (check-in: 4e1db8e9a9 user: drh tags: trunk) | |
14:38 | Space to hold the ".width" of columns in the CLI is now obtained from malloc() and hence is not limited in the number of columns supported. (check-in: 445ed5dab2 user: drh tags: trunk) | |
12:31 | Incremental improvements to tabular output modes in the CLI. The "markdown" and "table" modes no have headers turned on by default. (check-in: af28bff91a user: drh tags: trunk) | |
11:07 | Expand upon a comment in os_unix.c. No changes to code. (check-in: 77933dc4db user: dan tags: trunk) | |
00:21 | In the json output mode of the CLI, do correct quoting of escape characters. Also, show BLOBs as JSON strings, possibly with embedded \u0000 bytes. (check-in: 0278147a7d user: drh tags: trunk) | |
2020-05-28
| ||
23:49 | Progress toward adding new output modes to the CLI: json, table, and markdown. (check-in: 14f55fafec user: drh tags: trunk) | |
20:37 | Enhance the ".quote" mode in the shell so that it honors .separator. (check-in: b5e33ed537 user: drh tags: trunk) | |
00:45 | When the sqlite_stat1 data is missing for some indexes of a table but is present for the table itself or for other indexes in the same table, then do not let the estimated number of rows in that table get too small, as doing so can deceive the query planner into ignoring a perfectly good index. (check-in: 98d4262018 user: drh tags: trunk) | |
2020-05-27
| ||
12:44 | Small performance improvement and size reduction in the expression code generator. (check-in: eeb53e2195 user: drh tags: trunk) | |
00:02 | Change a datatype from i16 to int to appease Converity and help eliminate a false-positive. (check-in: 5b560ec490 user: drh tags: trunk) | |
