34 check-ins using file src/build.c version b47a0320

2017-08-28
17:00
Add the --enable-update-limit option to the ./configure script. check-in: 64a8ae68 user: drh tags: trunk
16:11
Avoid unnecessary mutexes in the pcache1 implementation in the common case where no auxiliary page cache memory is configured. check-in: 1ba051e3 user: drh tags: trunk
15:51
Remove the rarely-used scratch memory allocator. This makes the code smaller, faster, and easier to maintain. In place of the scratch allocator, add the SQLITE_CONFIG_SMALL_MALLOC configuration option that provides a hint to SQLite that large memory allocations should be avoided. check-in: 54b00024 user: drh tags: trunk
14:33
Backport changes to shell.c into shell.c.in. check-in: 2348045f user: drh tags: trunk
11:12
Fix the ".dump", ".schema", and ".fullschema" commands of the command-line shell so that they work even if PRAGMA empty_result_callbacks is enabled. Fix for ticket [02f0f4c54f281]. check-in: cf0d3715 user: drh tags: trunk
2017-08-27
10:55
Instrumentation and changes in an effort to reduce thread contention. Leaf check-in: c93298d5 user: drh tags: reduced-thread-contention
2017-08-25
19:51
Fix a few over-length source code lines. No functional changes. check-in: 1783c54c user: drh tags: trunk
15:43
Size and performance optimization for sqlite3Init(). check-in: 776d9128 user: drh tags: trunk
13:34
Small performance optimization in sqlite3WhereBegin(). check-in: 39f708d1 user: drh tags: trunk
13:02
Convert a branch made unreachable by [59560d07] into an assert(). check-in: 2738b8db user: drh tags: trunk
11:44
Improve the internal mechanism used to keep track of what kind of syncing to do for WAL transaction commits and checkpoint operations. Use the checkpoint-style of syncing to sync the header of a new or restarted WAL file. check-in: e8d23afe user: drh tags: trunk
09:17
Avoid returning duplicate rows in experimental pragmas "pragma_list", "module_list" and "function_list". check-in: b79cc8dc user: dan tags: trunk
01:14
Update the mechanism used to keep track of what kind of syncing to do for WAL transaction commits and checkpoint operations. Use the checkpoint-style of syncing to sync the header of a new or restarted WAL file. Closed-Leaf check-in: bf65dae8 user: drh tags: wal-sync-refactor
2017-08-24
20:54
Fix an incorrect hyperlink in a comment. check-in: 25292b9a user: drh tags: trunk
15:43
Fixes to documentation about SQLITE_OPEN_URI. check-in: 7ec72314 user: drh tags: trunk
13:55
Make sure the sqlite3_result_pointer() interface does not leave a VM register in an inconsistent state. Fix for ticket [7486aa54b968e9b5]. Test cases are in TH3. check-in: d2f9230c user: drh tags: trunk
2017-08-23
23:09
Performance optimization to pageFindSlot() in the b-tree layer. check-in: 59560d07 user: drh tags: trunk
20:36
Size and performance optimization to dropCell() and freeSpace(). check-in: bc1ec123 user: drh tags: trunk
14:45
Smaller and faster implementation of the fillInCell() routine. check-in: 77074990 user: drh tags: trunk
2017-08-22
21:23
Update documentation to make it clear that SQLITE_SOURCE_ID and sqlite3_sourceid() might changes if the source code is edited. check-in: e69c0c87 user: drh tags: trunk
21:07
Less dramatic changes to the source-id following an edit. Modify the way that the amalgamation is constructed to give it the opportunity to detect changes and modify the source-id. check-in: 564c7340 user: drh tags: trunk
19:54
Modify the SQLITE_SOURCE_ID if the source code has changed in any way since the previous check-in. check-in: 515d6a83 user: drh tags: trunk
19:49
Trying again to get out-of-tree builds to work correctly. Closed-Leaf check-in: a1b3337e user: drh tags: mksourceid
19:44
mksourceid still does not work right. Leaf check-in: ca5dcb4a user: drh tags: mistake
19:43
Attempting to fix the source-id generator so that it works for out-of-tree builds. check-in: 5a037ac2 user: drh tags: mksourceid
19:19
Add the "mksourceid" program to the build process. That program changes the SQLITE_SOURCE_ID if the source tree has been modified in any way. check-in: d4c05e04 user: drh tags: mksourceid
15:21
Fix error tests in seldom-used compile-time branches of the unix backend. check-in: 885c2b44 user: drh tags: trunk
2017-08-21
02:20
Remove an unnecessary conditional. check-in: 56d19f9f user: drh tags: trunk
02:05
Minor optimization to sqlite3VdbeMemSetStr(). check-in: 6538ef7b user: drh tags: trunk
2017-08-19
20:38
Space and size optimization to the printf implementation. check-in: d01d2cff user: drh tags: trunk
2017-08-18
22:30
Another size and performance optimization to readDbPage(). This time we eliminate some unnecessary local variables. check-in: 745bc8de user: drh tags: trunk
21:14
Size and performance optimization the readDbPage() routine in the pager. check-in: ca9e1875 user: drh tags: trunk
16:09
For the unix VFS, avoid an unnecessary stat() system call prior to opening any file in the common case where there are no unused file descriptors. check-in: 3075cfa0 user: drh tags: trunk
14:34
Combine the OP_CreateTable and OP_CreateIndex opcodes of the bytecode engine into a single OP_CreateBtree opcode. This simplifies the implementation and makes the bytecode programs clearer. check-in: eb1202b5 user: drh tags: trunk
