100 check-ins occurring around eeee6b71e5643511.

2007-05-15
14:17
Change the documentation to clearly state that the result of sqlite3_column_type() is undefined following a type conversion. (CVS 4007) (check-in: 960be575 user: drh tags: trunk)
14:10
Fix to check-in (4005). A call to sqlite3_column_blob() should not make subsequent calls to sqlite3_column_type() return SQLITE_BLOB. Sqlite3_column_type() returns the initial type. (CVS 4006) (check-in: b5e85deb user: drh tags: trunk)
13:27
Clarification on the best practices for using the _bytes() APIs. Change sqlite3_value_blob() to force the representation to be purely a BLOB and not a dual BLOB/String. Ticket #2360. (CVS 4005) (check-in: cf2dd45b user: drh tags: trunk)
11:55
A new approach for UTF-8 translation. (CVS 4004) (check-in: 6c8ad279 user: drh tags: trunk)
09:00
Do not allow bytes 0x80 through 0xBF to be the first character of an identifer because no valid UTF-8 character can begin with those bytes. If we allowed an identifier to begin with one of those bytes, then the substr() function in ALTER TABLE will not work correctly. (CVS 4003) (check-in: 25281042 user: drh tags: trunk)
07:14
Fix some test script errors in fuzz.test. (CVS 4002) (check-in: 51eeae7b user: danielk1977 tags: trunk)
07:00
A fix for queries that used correlated, compound sub-queries in the HAVING clause. Also update fuzz.test some more. (CVS 4001) (check-in: da0c1ab4 user: danielk1977 tags: trunk)
03:56
Fix problems in ALTER TABLE that occur when column or table names are invalid UTF encodings. (CVS 4000) (check-in: 9ff382f4 user: drh tags: trunk)
02:45
Fix a typo in a comment. Ticket #2359. (CVS 3999) (check-in: 1fbbc108 user: drh tags: trunk)
02:34
Fix a bug in sqlite3_mprintf() which could have caused a buffer overrun if malloc() failed. (CVS 3998) (check-in: 5af49a57 user: drh tags: trunk)
01:13
The built-in substr() function applied to a BLOB counts bytes, not characters. (CVS 3997) (check-in: 75d57308 user: drh tags: trunk)
00:09
Make sure the parser aborts quickly following a syntax error. (CVS 3996) (check-in: d07cdd3c user: drh tags: trunk)
2007-05-14
16:50
Fix a problem with ORDER BY and compound SELECT queries. (CVS 3995) (check-in: af76928f user: danielk1977 tags: trunk)
15:49
Fix a bug in "flattening" optimization. Occured if the parent of the flattened sub-query is also the parent of a sub-query that uses a compound op (i.e. UNION, INTERSECT etc.). (CVS 3994) (check-in: 1c33829c user: danielk1977 tags: trunk)
14:05
Prevent sub-queries with "LIMIT 0" from leaving an extra value on the vdbe stack. Also updates to fuzz.test. (CVS 3993) (check-in: b1d1b16e user: danielk1977 tags: trunk)
12:12
In the windows driver, reacquire the shared lock if an exclusive lock fails. Ticket #2354. (CVS 3992) (check-in: fc489b53 user: drh tags: trunk)
11:34
Remove terms with operator TK_AS from the expression tree. Ticket #2356. (CVS 3991) (check-in: 5627ff74 user: drh tags: trunk)
2007-05-12
15:00
Make REINDEX robust in the face of malloc() errors. (CVS 3990) (check-in: dbe41774 user: drh tags: trunk)
12:08
Make the ANALYZE command robust in the face of malloc() failures. (CVS 3989) (check-in: c08658e1 user: drh tags: trunk)
10:41
Fix another variant of the "IN (...)" b-tree problem. (CVS 3988) (check-in: 260338c4 user: danielk1977 tags: trunk)
09:30
Fix an obscure b-tree bug that applied to transient trees used for IN(...) expressions. (CVS 3987) (check-in: 96c7232f user: danielk1977 tags: trunk)
06:11
Bugfixes for assert() failures found by fuzz.test. (CVS 3986) (check-in: 2e80736d user: danielk1977 tags: trunk)

10:10
Expand the expressions tested by fuzz.test. Fix for (CAST zeroblob() AS text). (CVS 3983) (check-in: 4e1bb41f user: danielk1977 tags: trunk)

Fix a problem with inserting zeroblob() into an indexed column. (CVS 3982) (check-in: ccef5d2d user: danielk1977 tags: trunk)
01:44
Additional parsing bugs fixed. (CVS 3981) (check-in: d12a8924 user: drh tags: trunk)
00:20
Make sure that the REGISTER token generates a valid Expr. REGISTER will cause the tokenizer to abort, but the parser might do several reduce actions prior to that abort and those reduce actions sometimes need a valid Expr. (CVS 3980) (check-in: d146f01a user: drh tags: trunk)
2007-05-10
21:31
Backport the stack-size reduction patch in (3673) to version 3.3.13. (CVS 3979) (Leaf check-in: e91012b6 user: drh tags: branch_3_3_13)

17:23
Add some UTF-8 test infrastructure. Treat NaN as NULL. The printf routines print infinity as "Inf" not as "NaN". Ticket #2345. (CVS 3972) (check-in: ffe615a7 user: drh tags: trunk)
15:37
Add new test file fuzz.test, to test SQLite with fuzzily generated SQL. (CVS 3971) (check-in: 1e9e6fe7 user: danielk1977 tags: trunk)

Fix a C++ism in func.c. (CVS 3970) (check-in: 9c0050a1 user: drh tags: trunk)
11:43

12:37
Do not crash in the internal functions sqlite_rename_table() or sqlite_rename_trigger() if they are somehow passed unexpected input. (CVS 3944) (check-in: c2f90b46 user: danielk1977 tags: trunk)
