| 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) | |

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

|
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

| 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
| ||

| 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

| 11:10 | Changes to sqlite3SelectNew() to work around a false-positive warning from GCC-10. The code is very slightly larger and slower as a result. (check-in: 04e1edd8e5 user: drh tags: trunk) | |
| 10:54 | Innocuous changes to help Coverity avoid false-positives. (check-in: 4ec8a5a203 user: drh tags: trunk) | |
