14:40
Revise the layout of filenames in the Pager object so that it is unchanged from prior versions. It turns out that some important 3rd-party software does questionable pointer manipulations on those filenames that depend on that legacy layout. Technically, this is a misuse of SQLite by the 3rd-party software, but we want to avoid unnecessary breakage. (check-in: 34ab7606 user: drh tags: trunk)
2020-01-23

21:34
Allow non-deterministic function in CHECK constraints. It turns out that PostgreSQL, MySQL, and SQLServer all allow this. We should be the the exception. Ticket [830277d9db6c3ba1] (check-in: 8c8ce526 user: drh tags: trunk)
19:58
Fix a couple of test case issues on this branch. (check-in: 9830a44b user: dan tags: reuse-schema)
19:46

2020-01-17
23:27
Fix a typo in a comment. No code changes. (check-in: 4363f69c user: drh tags: trunk)
21:12
The compress() function should not be deterministic since the same input can have multiple possible compressed outputs. The uncompress() function, on the other hand, is deterministic. (check-in: 84f31490 user: drh tags: trunk)
19:14
Fix #ifdefs so it compiles cleanly with all SQLITE_OMIT compile-time options. Update compile-time option testing. (check-in: 7584e4b6 user: drh tags: trunk)
16:47
Improved rounding in the 'unixepoch' feature of the date and time functions. (check-in: c9abf1bd user: drh tags: trunk)
15:45
Update test script instrfault.test to account for the fact that bound blob values cast to text values are now intepreted using the text encoding of the database, instead of always as utf-8. (check-in: 4d6cb288 user: dan tags: trunk)

Do not allow shadow tables to be dropped in defensive mode. (check-in: ad1f760f user: drh tags: branch-3.28)
14:30
Import the 3.31.0-beta FTS3/4 code directly into the 3.28 branch, thus providing 3.28 with all the latest 3.31 fixes. FTS3 has not been enhanced to use any core functionality that was not already available in 3.23, so no modifications were made to FTS3 sources for this import. (check-in: be4269c6 user: drh tags: branch-3.28)
14:18
Import all FTS3/4 enhancements and fixes that exist on the latest trunk (3.31.0-beta) that do not require extensive change to the SQLite core into the 3.22 branch. Basically, the 3.31.0 FTS3 sources are copied into 3.22.0, with minor changes to work around core enhancements that are not available in 3.22.0. (Leaf check-in: cbcbb1e5 user: drh tags: branch-3.22)
11:18
Fix a case in "fuzz.test" that could fail, as non-deterministic functions may no longer appear in CHECK constraints. (check-in: a370871e user: dan tags: trunk)
2020-01-16
17:53
New testcase() macros in select.c, for coverage of the change from two check-ins ago. (check-in: 52206488 user: drh tags: trunk)

13:02
Very small performance improvement by ensuring that the argument to sqlite3VdbeFreeCursor() is non-NULL. Hold for the next sprint. (Leaf check-in: f8801ffd user: drh tags: close-cursor-faster)

16:20
Do not allow the "PRAGMA encoding" statement to change the database encoding if TEMP content exists, or content in any other attached database. Formerly, encoding changes were allowed if just the main database file was empty. Ticket [a08879a4a476eea9]. (check-in: 03b003c9 user: drh tags: trunk)
14:26
Merge all recent enhancements and fixes from trunk. (check-in: f7839178 user: drh tags: reuse-schema)

13:33
Documentation updates. No changes to code. (check-in: cc0e0aa3 user: drh tags: trunk)
2020-01-12
22:38
Better than removing the incorrect assert() is to change it into a testcase() together with a comment indicating where an appropriate test case can be found, and the ticket that provoked the change. Ticket [614b25314c766238] (check-in: 3e3c60d8 user: drh tags: trunk)
22:25
Change the zipfile virtual table so that the xBestIndex method gives a reasonable cost estimate even if no filename is specified. The missing filename error continues to be raised in the xFilter method. Meanwhile, the more reasonable cost estimate avoids unnecessary wierdness in the query planner. (check-in: 0e468aa6 user: drh tags: trunk)
22:20
Remove an incorrect assert(). Fix for ticket [614b25314c766238] (check-in: 6a999c5a user: drh tags: trunk)
2020-01-11
21:08
New apis: sqlite3_filename_database(), sqlite3_filename_journal(), and sqlite3_filename_wal(). Also sqlite3_uri_key(). And the other sqlite3_uri functions now work using the journal or wal filename in addition to the database file. And the sqlite3_db_filename() result is guaranteed to work as an argument to the sqlite3_uri functions. (check-in: fd7bcc53 user: drh tags: trunk)
20:27
Minor changes for consistency between sqlite3_filename_wal() and sqlite3_filename_journal(). (Closed-Leaf check-in: 9a70ff43 user: drh tags: enhanced-uri)
16:08
Redesign for better legacy compatibility. Add the sqlite3_uri_key() interface. (check-in: bcb43d11 user: drh tags: enhanced-uri)
2020-01-10
18:05
Rearchitect the way in which filenames are stored in the Pager object so that the sqlite3_uri_parameter() interface will work from journal and WAL filenames too. This check-in implements the central idea, and compile and runs somewhat, but crashes on an extended test. (check-in: 2ae77bd2 user: drh tags: enhanced-uri)
01:05
Fix to the register validity tracking logic in debug builds. No impact on release builds. (check-in: 0a500da6 user: drh tags: trunk)
00:20
Begin making changes to turn off trusted schema in command-line tools that open SQLite databases. There are a lot of these, and a lot of places to change, which makes me wonder if trusted schema should be off by default. (Leaf check-in: 3d23a275 user: drh tags: default-untrusted-schema)
00:00
Documentation updates on newer APIs. No changes to code. (check-in: 8845a8c2 user: drh tags: trunk)

20:48
In the typeof() optimization in OP_Column, expand the size of the bogus buffer provided for data so that it is big enough to cover the increased number of bytes displayed during register tracing from check-in [54553bf16fabd72d]. This is the correct fix for ticket [bbd55a97e66ff50d], though the earlier one does not hurt and is useful to retain. (check-in: e1154c39 user: drh tags: trunk)

Rewrite the (debugging use only) sqlite3VdbeMemPrettyPrint() function to use the safer StrAccum interface rather than writing directly into a static string buffer. Perhaps this will address ticket [bbd55a97e66ff50d], which we are unable to reproduce. (check-in: 69f6a7e4 user: drh tags: trunk)
18:59
Backout change [4d0b9109f7a5312d4e1] because the conditional it added is no longer reachable due to check-in [1409758f72c0206c]. (check-in: b3f26967 user: drh tags: trunk)

17:42
New test cases in test/in4.test require rtree, so disable those tests on builds that lack the rtree extension. (check-in: b5900914 user: drh tags: trunk)
16:55
Fix a problem where the loop for the RHS of a LEFT JOIN uses values from an IN() clause as the second or subsequent field of an index. (check-in: 95ef6896 user: dan tags: trunk)
15:37
Merge the latest fixes from trunk. (check-in: 26ef709a user: drh tags: new-security-options)

14:57
Improve a testcase in test/fuzzdata8.db to make it more resilient. (check-in: 139aefe6 user: drh tags: trunk)
14:50
Back out another NEVER added by check-in [7b62555e285f32d3] - the test case was already in test/fuzzdata3.db, but it only occurs if compiled without SQLITE_ENABLE_PREUPDATE_HOOK. (check-in: 61f873b1 user: drh tags: trunk)
14:00
Omit the omit flag from eq constraints on column "aggregate" of dbstat virtual tables. Fix for [727074e2]. (check-in: 74ef6f2b user: dan tags: trunk)
12:34
Restore a NEVER and an assert in btree that was removed by check-in [7b62555e285f32d3]. Dbsqlfuzz found test cases. (check-in: 04a05c83 user: drh tags: trunk)
01:43
Enhance PRAGMA function_list so that it shows all instances of each FuncDef, the number of arguments, the encoding, the type, and the flags. Use this capability to locate and fix incorrect function flags in the standard build. (check-in: 9ca906d2 user: drh tags: new-security-options)
2020-01-03
21:57
Invert the SQLITE_FUNC_SAFE bit to be SQLITE_FUNC_UNSAFE. The external bit is still SQLITE_INNOCUOUS. It gets inverted as the appdef function is registered. (check-in: 1c266cb3 user: drh tags: new-security-options)

14:16
Fix the OP_Copy-coalesce optimization so that if the previous row happens to end with OP_Copy but is not a candidate for the optimization due to jumps, then the optimization is correctly bypassed. (check-in: b36126c1 user: drh tags: trunk)
13:55
Ensure that when a Select object is reset a new, empty, SrcList is allocated. (check-in: 4889cbf8 user: dan tags: trunk)
02:20
When generating the name of a view (or common table expression) because the SQL does not specify a name, avoid the names "true" and "false" which might be confused for the boolean literals of the same name, leading to an inconsistent abstract syntax tree. (check-in: ff9492d3 user: drh tags: trunk)
00:28
Fix a problem in sqlite3TreeViewBareExprList() in which the routine was not interpreting the new ExprList format correctly. (check-in: cd56872a user: drh tags: trunk)

23:50
Merge enhancements from trunk. (check-in: 091403a6 user: drh tags: new-security-options)
