2019-08-08
15:47
Fix spurious "no such table: x1" errors in shared-schema mode that could occur when a query that is a join across two or more databases needs to call the xConnect() methods of a virtual table. (check-in: edf45cd7 user: dan tags: reuse-schema)

Fix an obsolete comment in the CLI. No code changes. (check-in: fade103c user: drh tags: trunk)
21:56
In the CLI, code the "sqlite_parameters" name directly rather than using a macro, for clarity of presentation for users who are reading the code for the purpose of seeing how the CLI implements parameter binding. (check-in: e775ef00 user: drh tags: trunk)

19:50
Earlier detection of corruption while added to the freelist. (check-in: 8c80b004 user: drh tags: trunk)

Improvements to the help text in the CLI. (check-in: 919fec91 user: drh tags: trunk)
15:06
Fix the writefile() SQL function implemented by ext/misc/fileio.c such that any directories created have standard umask permissions, not permissions of the file that is to be written. (check-in: f11c8959 user: drh tags: trunk)
14:24
For the ".archive --update" command in the CLI, only update files if their mtime or mode has changed. To force an update, use the new --insert instead. (check-in: 191a023a user: drh tags: trunk)
2019-03-22
13:53
We learn that readdir_r() is deprecated in favor of plain old readdir(), which is now suppose to be threadsafe using thread-local storage. So remove the use of readdir_r() from the test code. (SQLite itself never calls readdir() or readdir_r()). (check-in: 7a0a26ed user: drh tags: trunk)
11:38
Add the --limit N option to dbfuzz2. Set the default callback limit to 250K. (check-in: b99f8512 user: drh tags: trunk)

Use the IsReuseSchema() macro more consistently. Also, rename it to IsSharedSchema(). (check-in: c1be211c user: dan tags: reuse-schema)
19:17
Fix an error message. (check-in: a70fdaa3 user: dan tags: reuse-schema)
18:22
In the CLI, give better error messages if something goes wrong with the ".dbinfo" command. (check-in: 3649a77b user: drh tags: trunk)
16:58
Fix a potential dangling pointer deference in an ALTER TABLE run on a schema that contains constructs of the form "PRIMARY KEY(column COLLATE collation)". (check-in: b9e2393c user: dan tags: trunk)
16:03
Merge latest trunk changes into this branch. (check-in: 4cd20ca6 user: dan tags: reuse-schema)

Fix harmless compiler warnings from MSVC. (check-in: f0f02d46 user: drh tags: trunk)
11:16
Enhance the rtreenode() function of rtree (used for testing) so that it uses the newer sqlite3_str object for better performance and improved error reporting. Test cases added to TH3. (check-in: 90acdbfc user: drh tags: trunk)
05:45
Fix various harmless compiler warnings seen with MSVC. (Closed-Leaf check-in: 1c0fe5b5 user: mistachkin tags: noWarnings)
2019-03-19

Enhance the VACUUM INTO command so that it works on read-only databases. (check-in: 55be6d0a user: drh tags: trunk)
20:13
Fix a compiler warning in FTS5. (check-in: d5acf3af user: drh tags: trunk)
15:36
When computing the amount of scratch memory needed during a rebalance operation, assume the worst case for the number of cells per page, rather than relying on the BtPage.nCell value, which might be incorrect for a corrupt database. (check-in: a420ebd0 user: drh tags: trunk)
11:35
Tweak the tool/cg_anno.tcl script so that it can run on systems without /usr/bin/tclsh. (check-in: a026189a user: dan tags: trunk)
09:57
Add a LICENSE.md, containing the text of the blessing. (check-in: cbb7e602 user: drh tags: trunk)
2019-03-18
15:49
Fix a buffer overread that could occur when running fts5 prefix queries inside a transaction. (check-in: b3fa58dd user: dan tags: trunk)

2019-03-05
23:49

14:39
If the initial byte of a record is a large value, then always used the generalized record comparison routine sqlite3VdbeRecordCompare() rather than one of the specialized versions that are optimized for shorter records. (check-in: c1ac0070 user: drh tags: trunk)
2019-03-04
07:25
Merge latest trunk changes into this branch. (check-in: 97a9604d user: dan tags: reuse-schema)
07:15

Improved comments on the fossildelta.c extension. (check-in: d7d23f04 user: drh tags: trunk)
15:25
Fix the SQLITE_DIRECT_OVERFLOW_READ compile-time option so that it works with SQLITE_HAS_CODEC. (check-in: fd085e92 user: drh tags: trunk)
12:17
Remove a redundant parameter extraction call from the percentile.c extension. (check-in: d49c32e6 user: drh tags: trunk)
2019-03-01
21:33
The fts3_tokenizer() function returns NULL if the SQLITE_DBCONFIG_ENABLE_FTS_TOKENIZER setting is disabled, which is is by default. (check-in: f5732f4c user: drh tags: trunk)
21:12
Fix a minor comment typo. No code changes. (check-in: 9a0a93c8 user: drh tags: trunk)
18:07
In a query that uses a partial index, the expression that is the WHERE clause of the partial index must always be true. Use this fact to avoid evaluating identical terms in the WHERE clause of the query. (check-in: 9b287962 user: drh tags: trunk)

Add new test file reuse5.test. For testing the shell tool ".shared-schema" command. (check-in: fa6008d5 user: dan tags: reuse-schema)
16:11
Fix a harmless compiler warning that only comes up during debug builds. (check-in: 848869ce user: drh tags: trunk)
15:43
Add the ".shared-schema check|fix DB1 DB2..." command to the shell tool. For checking if a database is eligible to share an in-memory with the main database, and for fixing small problems that prevent it from being so. (check-in: 7d8e8a95 user: dan tags: reuse-schema)
12:29
Update the configure-generated makekfile to generate a portable pkgIndex.tcl. (check-in: 35cbee7f user: drh tags: trunk)

20:48
Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. (check-in: 84162af5 user: dan tags: trunk)
00:21
Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and also a fix to make it right. Then add an alternative fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. (check-in: d3915230 user: drh tags: trunk)
00:08
Remove a testcase() macro which is now unreachable due to the contraction of the use of IN_INDEX_ROWID. (Closed-Leaf check-in: 90c5a17c user: drh tags: tkt-df46dfb631)
2019-02-22
23:29
Make all ephemeral tables built to hold the RHS of an IN operator be index-btrees, never table-btrees, regardless of whether or not they are used as IN_INDEX_LOOP or IN_INDEX_MEMBERSHIP. That way, the same ephmerial table can be reused for both cases. (check-in: c2d50df8 user: drh tags: tkt-df46dfb631)
21:33
Check-in [fa792714ae62fa980] is not a valid fix for ticket [df46dfb631f75694], as the new test case in this check-in demonstrates. The fix here causes test cases for the [df46dfb631f75694] bug to fail again, so this check-in is on a branch. A new fix is needed for [df46dfb631f75694]. (check-in: 0d456456 user: drh tags: tkt-df46dfb631)
19:24
Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. Fix for [4feb3159c6]. (check-in: 579b66ea user: dan tags: trunk)
17:44
Merge latest trunk changes into this branch. (check-in: 001771af user: dan tags: reuse-schema)
16:18
In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. (check-in: 73056b31 user: drh tags: trunk)
15:42
Modify sqlite3_str_finish() and sqlite3VMPrintf() so that they always return NULL on any OOM or SQLITE_LIMIT_LENGTH error. (check-in: e7144ffd user: drh tags: trunk)
2019-02-21
16:41
Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. (check-in: c13d5639 user: drh tags: trunk)
2019-02-20
19:20
Changes to the unix VFS that allegedly enable it to build of Fuchsia. We have no way of testing this. (check-in: be21a641 user: drh tags: trunk)
19:06
Disable unix-specific features of dbfuzz2 when compiling on windows. (check-in: af84774d user: drh tags: trunk)
18:44
Further test cases and fixes for SQLITE_OPEN_SHARED_SCHEMA. (check-in: ba0ab042 user: dan tags: reuse-schema)
