16 check-ins using file src/test_window.c version add59ee6

2018-07-01
16:05
Quick patch to the Lemon parser template to avoid an array overread reported by OSSFuzz. A proper fix involves enhancements to the table generators in Lemon to make the overread impossible. That fix will take longer to implement. The current check-in is a stop-gap. (check-in: 3f6730be user: drh tags: trunk)

20:26
Avoid a warning in fts5.c due to not using generated routine sqlite3Fts5ParserFallback(). (check-in: 65ff5144 user: dan tags: trunk)
20:15
Merge implementation of SQL window functions from the exp-window-functions into trunk. (check-in: 17198a12 user: dan tags: trunk)
20:00
Fix a minor problem in the code for determining whether or not an SQL statement is SQLITE_TOOBIG. (Closed-Leaf check-in: 763e6c9e user: dan tags: exp-window-functions)
19:12
Merge all changes from the weak-fallback branch except those related to the weak-fallback feature itself. (check-in: aad718fb user: dan tags: exp-window-functions)
18:54
Have the tokenizer handle fallback for tokens "OVER" and "FILTER" in the same way as it does for "WINDOW". (Leaf check-in: 12d819e1 user: dan tags: weak-fallback)
2018-06-29
20:43
Further performance related tweaks for sqlite3RunParser(). (check-in: 5eb47765 user: dan tags: weak-fallback)
20:21
Further tweaks to sqlite3RunParser(). (check-in: eef61ffa user: dan tags: weak-fallback)
19:54
Improve on the previous checkin. Still a bit slow. (check-in: c1fb41aa user: dan tags: weak-fallback)
17:44
Instead of using a lemon %fallback directive, have the tokenizer try to figure out whether an instance of "WINDOW" should be TK_WINDOW or TK_ID. (check-in: 022079cb user: dan tags: weak-fallback)
2018-06-28
20:05
Modifications to parse.y to better support backwards compatibility for the "window" keyword. (check-in: 7c4b879b user: dan tags: weak-fallback)
03:38
Introduce the concept of "weak fallback" in the parser. A weak fallback only occurs if a syntax error would result otherwise. (check-in: c41d7079 user: drh tags: weak-fallback)
2018-06-27
20:24
Add missing VdbeCoverage() and VdbeCoverageNeverTaken() macros to window.c. (check-in: 4383cb68 user: dan tags: exp-window-functions)
19:48
Avoid redundant ORDER BY operations when rewriting SELECT statements that contain window functions. (check-in: 336de43a user: dan tags: exp-window-functions)
2018-06-26
20:19
Merge latest trunk changes. (check-in: d9f814b4 user: dan tags: exp-window-functions)
2018-06-25
20:34
Add documentation comment for sqlite3_create_window_function(). And further tests. (check-in: 3f2705b9 user: dan tags: exp-window-functions)
