24 check-ins using file src/prepare.c version 1eaeccc1

2017-08-07
14:06
Fix a bug on this branch involving mmap mode and readonly transactions. (check-in: 355c594e user: dan tags: server-process-edition)
2017-08-01
19:53
Split the OP_Last opcode into OP_Last and OP_SeekEnd. Use OP_SeekEnd to position a cursor prior to appending. Ticket [cb91bf4290c211d]. (check-in: 3e02474c user: drh tags: trunk)
14:16
Take advantage of atomic-write capabilities in the F2FS filesystem when the database is stored on such a filesystem. This is a compile-time option activated using SQLITE_ENABLE_BATCH_ATOMIC_WRITE. (check-in: 24190b22 user: drh tags: trunk)
13:54
Merge recent enhancements from trunk. (check-in: aafe1fec user: drh tags: begin-concurrent)
00:20
Allow ATTACH and DETACH inside of a transaction. (check-in: 95e8f316 user: drh tags: trunk)
2017-07-31
19:55
Add documentation file ./README-server-edition.html. (check-in: fbc4f4ad user: dan tags: server-process-edition)
19:39
Recognize 'AMD64' as 'x64' in the TclKit batch tool for MSVC. (check-in: 0c77935c user: mistachkin tags: trunk)
19:26
Sync up the MSVC autoconf makefile. (check-in: b3b89f4f user: mistachkin tags: trunk)
17:51
Fix a windows-compatibility issue in the recently added schema6.test script. (check-in: 14e6c302 user: drh tags: trunk)
17:06
Prevent OSSFuzz from using debugging pragmas that are disabled in default builds and which generate lots of excess output. (check-in: cdc6494c user: drh tags: trunk)
16:42
Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening. This prevents the names from getting mangled by query transformations, and obviates hacks in the query flattener that attempt to work around the name mangling. The resulting code is smaller and faster and gives more consistent output. Fix to ticket [de3403bf5ae5f72ed]. (check-in: ade7ddf1 user: drh tags: trunk)
2017-07-30
19:50
Add the schema6.test module for demonstrating schemas that generate identical and different content. (check-in: ac1da06a user: drh tags: trunk)
18:40
Correctly handle an "INTEGER PRIMARY KEY UNIQUE" column in a WITHOUT ROWID table. This is a fix for ticket [bc115541132dad136], a problem discovered by OSSFuzz. (check-in: 5216bfb7 user: drh tags: trunk)
2017-07-29
17:10
Merge latest trunk changes with this branch. (check-in: b42c8779 user: dan tags: server-process-edition)
17:02
New test cases for column name generation interacting with the query flattener. (Closed-Leaf check-in: 0c38dde4 user: drh tags: early-column-names)
16:01
Move the generation of output column names earlier, to right after name resolution and before query transformations such as flattening. This prevents the names from getting mangled by query transformations, and obviates hacks in the query flattener that attempt to work around the name mangling. The resulting code is smaller and faster and gives more consistent output. This is an alternative fix to ticket [de3403bf5ae5f72ed]. (check-in: 09834279 user: drh tags: early-column-names)
14:56
Use the subquery column name, not the original SQL statement text, as the added AS clause in the query flattener. (Closed-Leaf check-in: 5df7f0e6 user: drh tags: flattener-column-names)
03:33
In the query flattener, only add AS clauses to output columns of the outer query that are copied directly from the inner query. Formerly, all columns of the outer query received an AS clause if they did not have one already. This is a proposed fix for ticket [de3403bf5ae5f72]. (check-in: 439cc5c5 user: drh tags: flattener-column-names)
2017-07-28
22:22
Update Tcl version used by the TclKit batch tool for MSVC. (check-in: bcec155e user: mistachkin tags: trunk)
22:13
Fix harmless compiler warning. (check-in: 3286e1a0 user: mistachkin tags: trunk)
2017-07-27
20:24
Enhance the like optimization so that it works with an ESCAPE clause. (check-in: f5d330f4 user: drh tags: trunk)
19:59
Increase the version number to 3.21.0 in anticipation for changes to go into the next release. (check-in: 0645f25c user: drh tags: trunk)
18:49
Merge the pointer-passing interface changes from the 3.20 branch. (check-in: c63903a4 user: drh tags: trunk)
2017-07-26
19:59
Add the new sqlite3.mDbFlags field. Factor out bits of sqlite3.flags that do not interact with PRAGMA statements into sqlite3.mDbFlags. (check-in: 3808a00f user: drh tags: trunk)
