39 check-ins using file ext/fts3/fts3_write.c version f33df167

2019-01-22
02:34
Ensure that a key comparison does not read a collating sequence past the end of the KeyInfo, even if the key field of an index is corrupted by having a string in the last column instead of the ROWID. (check-in: 058a8006 user: drh tags: trunk)
2019-01-21
23:18
Enhance the btree search routine so that it does early detection of impossibly large keys and thereby avoids a large malloc() call. (check-in: 3ecaaee6 user: drh tags: trunk)
17:57

16:12
Remove a faulty assert() from fts3. (check-in: 6c33a303 user: dan tags: trunk)
16:01
Make sure the extra bytes allocated for the saved cursor position by check-in [160b1e31c0f27257] are initialized to zero. (check-in: 27375649 user: drh tags: trunk)
14:55

Minor fix the fallocate.test module change from [7cd56cad5efead5] (check-in: 94fb7a47 user: drh tags: trunk)
13:47
Add the --max-data and --max-as options to dbfuzz2. Also cause dbfuzz2 to show its maximum RSS size upon exit in standalone mode with the -v option. (check-in: 7ce93e82 user: drh tags: trunk)
2019-01-20
00:03
Add the --max-stack option to dbfuzz2. (check-in: c11ae4fe user: drh tags: trunk)
2019-01-19
15:55
Avoid a division-by-zero error in fts5 caused by a corrupt database. (check-in: 928e6221 user: dan tags: trunk)
15:27
Remove a broken assert() triggered by a "PRAGMA max_page_count = N" invocation, where N is larger than the number of pages in the database image, but smaller than the number of pages in the database file. (check-in: 7cd56cad user: dan tags: trunk)
14:07
Fix a problem with using ALTER TABLE to rename a table or column when the database schema contains a trigger or view that itself contains an expression "<column> AND 0". (check-in: 908ff7ff user: dan tags: trunk)
2019-01-18
21:17
Fix a memory leak introduced by [55c5d72a]. (check-in: fbd681dc user: dan tags: trunk)
21:12
Fix a crash in the fts5vocab module caused by including a "term < NULL" term in a WHERE clause. (check-in: 9e717c43 user: dan tags: trunk)
21:03
Fix an infinite loop caused by a corrupt database in fts3. Also an undefined left-shift in fts5. (check-in: 55c5d72a user: dan tags: trunk)
20:15
Avoid passing a NULL pointer to memcpy in fts5, even if the database is corrupt. (check-in: acccc980 user: dan tags: trunk)
19:33
Typecasts added to the GeoPoly extension to avoid harmless UBSAN warnings. (check-in: a1f6a093 user: drh tags: trunk)
19:26
Fix problems causing undefined left-shift operations in the fts3 snippet() function. (check-in: b90dbaed user: dan tags: trunk)
18:52
Avoid integer overflow when computing the array of a bounding box with the rtree_i32 virtual table. (check-in: b352f159 user: drh tags: trunk)
17:53
Handle oversize floating point values carefully when converting to integers for the '%' binary operator. (check-in: 048add13 user: drh tags: trunk)
16:06
Fix a fairly obscure problem allowing an "ALTER TABLE RENAME col TO ..." statement to modify the schema in such a way as to break a reference within a trigger program. (check-in: 64bec9e6 user: dan tags: trunk)
14:53
Use the full 64-bit integer value in the argument to randomblob(). (check-in: 05df5f7a user: drh tags: trunk)
2019-01-17
20:19
Disable the xfer-optimization if the two tables have the same root page due to schema corruption. (check-in: f31b3bd2 user: drh tags: trunk)
20:06
Fix another corruption related crash in fts5. (check-in: 4538d9af user: dan tags: trunk)
19:33
Add the SQLITE_ENABLE_EARLY_CURSOR_CLOSE compile-time option which causes read cursors to be closed after their usefulness ends during a two-pass UPDATE. (check-in: 7def6c8e user: drh tags: trunk)
19:11
Fix a buffer overwrite that could occur when running an fts5 prefix query against a corrupt database. (check-in: 3910b563 user: dan tags: trunk)
17:39
Fix problems with joining two or more fts5_vocab tables that access the same underlying fts5 table. (check-in: 49956395 user: dan tags: trunk)
15:47
Sync up with the latest enhancements on trunk. (check-in: 475a179a user: drh tags: apple-osx)
15:40
Revamp the SrcList allocator routines to be methods of Parse instead of being methods of the "sqlite3" object, so that they can leave better error messages when the SrcList object grows too large. (check-in: df08d472 user: drh tags: trunk)
14:34
Limit the size of SrcList objects to 200 entries (compile-time configurable using -DSQLITE_MAX_SRCLIST=n). The maximum number of tables in a join has always been 64, so this is not a real constraint on capability. Limiting the size of a SrcList prevents DOS attacks (discovered by OSSFuzz) using crazy nexted CTE joins. (check-in: 7cac614d user: drh tags: trunk)
04:40
Fix a corner-case for the logic that cause an insert of a NULL into an INTEGER PRIMARY KEY column to be converted into a valid integer key, when the NULL results from a CASE expression that lacks an ELSE clause. (check-in: 9a425051 user: drh tags: trunk)
03:43
Ensure that the variable-length integer decoder in FTS3 never tries to left-shift a negative number. (check-in: 10ffc1fe user: drh tags: trunk)
01:06
Fix a failure in sqlite3ExprCompare() (check-in: 835e2cc5 user: drh tags: trunk)
2019-01-16
20:48
Fix a problem with fix [b4b57413]. (check-in: ca7b7aae user: dan tags: trunk)
19:44
Fix a problem in the fts3 matchinfo() function with corrupt database handling. (check-in: 24ed5fb6 user: dan tags: trunk)
19:26
Fix a problem in the code generator for sorting results with SRT_EphemTab and a LIMIT clause. (check-in: 49fcde2f user: drh tags: trunk)
14:58
Fix a problem with renaming a column that is used as part of an ORDER BY on a compound SELECT within a database view or trigger. (check-in: b4b57413 user: dan tags: trunk)
12:05
Avoid a dangling pointer comparison when renaming a table that has a trigger that itself contains a window function with an (illegal) column reference in a FOLLOWING expression. (check-in: d45bee36 user: dan tags: trunk)
11:38
Fix a memory leak that could occur in fts3 when handling a corrupt database. (check-in: 65cebb06 user: dan tags: trunk)
