32 check-ins using file src/sqlite.h.in version 1971ab97

2017-01-27
19:27
Add the sha1.c loadable extension that implements the sha1() and sha1_query() SQL functions. check-in: 24e77c1c user: drh tags: trunk
17:02
Fix a problem causing the pre-update hook to be invoked by DROP TABLE statements. check-in: fbb6bf1b user: dan tags: trunk
16:24
Merge all recent enhancements from trunk. check-in: fe86ff54 user: drh tags: est_count_pragma
13:14
Alternative ICU fix (compare to check-in [50e60cb4]) that avoids casting integers to pointers. check-in: d9752c8f user: drh tags: trunk
01:52
In the command-line shell, enhance the ".mode" command so that it restores the default column and row separators for modes "line", "list", "column", and "tcl". check-in: 58f02e6e user: drh tags: trunk
01:25
Another micro-optimization in accessPayload(). Slightly smaller and faster. check-in: c012619b user: drh tags: trunk
01:13
Performance optimization in accessPayload(). check-in: ebb1fd98 user: drh tags: trunk
00:31
Simplify the accessPayload() routine so that it always populates the overflow page cache. In the one case where populating the page cache can lead to problems, simply invalidate the cache as soon as accessPayload() returns. This simplification reduces code size and helps accessPayload() to run a little faster. This backs out the eOp==2 mode of accessPayload() added by check-in [da59198505]. check-in: 68e7a8c6 user: drh tags: trunk
2017-01-26
21:30
Remove an unreachable branch in the error handling logic for sqlite3BtreePayloadChecked(). check-in: 293bf3ed user: drh tags: trunk
18:00
Improvement to the OP_Permutation opcode to prevent it from using CPU cycles for initialization in prepared statements that do not use that opcode. check-in: b4a98f65 user: drh tags: trunk
17:26
Remove the obsolete lastRowid cache from the sqlite3VdbeExec() for a size reduction and performance improvement. check-in: b4803184 user: drh tags: trunk
17:11
Performance optimization in sqlite3VdbeCloseStatement(). check-in: 1e96e5ec user: drh tags: trunk
16:54
Performance optimization to sqlite3_blob_read(). check-in: 7459f4b7 user: drh tags: trunk
16:27
Minor simplification and performance optimization for Direct Overflow Read. check-in: 3e96d6ef user: drh tags: trunk
02:26
Make SQLITE_DIRECT_OVERFLOW_READ work for in WAL mode as long as the page being read is not in the the -wal file. check-in: 9879be18 user: drh tags: trunk
01:54
Enhancements to the kvtest utility program. Add the --jmode option. Improved output formatting. check-in: 62a4851c user: drh tags: trunk
00:58
Modify the ICU extension to use a static initializer, as VC++ complains about a dynamic initialization. Maybe the dynamic structure initialization is a GCC extension. This fixes a problem identified on the SQLite mailing list by Ziemowit Laski. check-in: 50e60cb4 user: drh tags: trunk
2017-01-25
20:55
Trim NULL values off the end of records when the SQLITE_ENABLE_NULL_TRIM compile-time option is used. Increase the size of the P5 operand to 16 bits. Fix a problem with short records in the sessions extension. check-in: 4801bd59 user: drh tags: trunk
18:53
Fix another pre-update hook issue, this time in sqlite3preupdate_old(). Closed-Leaf check-in: c7651d21 user: dan tags: trim-nulls
18:12
Fix a test script problem in exclusive2.test causing it to fail on this branch. check-in: f66614dc user: dan tags: trim-nulls
17:44
Fix a problem with the pre-update hook on this branch. check-in: 6fc4fbfa user: dan tags: trim-nulls
14:58
Experimental enhancement to automatically trim NULL values from the end of records, for a reduced disk footprint. This change also involves increasing the P5 operand from 8 to 16 bits. check-in: 118ded40 user: drh tags: trim-nulls
14:38
Ensure that sqlite3_blob_reopen() correctly handles short rows. Fix for ticket [e6e962d6b0f06f46e]. check-in: 8cd1a445 user: drh tags: trunk
13:54
Fix SQLITEINT_H macro usage in two extensions. check-in: 0803390c user: drh tags: trunk
04:41
Ensure that sqlite3_blob_reopen() correctly handles short rows. Proposed fix for ticket [e6e962d6b0f06f46e]. Further testing needed. Closed-Leaf check-in: 57d8dad3 user: drh tags: blob_reopen-fix
2017-01-23
19:11
Document the --mmap option in the --help screen for kvtest. Enhance kvtest so that numeric arguments can have suffixes like "K" or "M". Add kvtest to the unix makefiles. check-in: 175bda87 user: drh tags: trunk
18:40
Add the --mmap option to the kvtest utility program. check-in: 4948f7e6 user: drh tags: trunk
16:56
Optimization: Try to avoid unnecessary btree searching when repositioning a cursor to the next row. check-in: ee793d30 user: drh tags: trunk
15:58
Add the missing SQLITE_API symbol to test_delete.c (it is not added automatically as this file is not part of the amalgamation). check-in: 7a4f512d user: dan tags: trunk
07:06
Fix a problem preventing FTS5 from correctly passing the FTS5_TOKENIZE_PREFIX flag to custom tokenizer implementations. check-in: 03c60134 user: dan tags: trunk
2017-01-22
16:34
Fix an uninitialized variable in the command-line shell. check-in: 06b8001a user: drh tags: trunk
02:04
Fixes to documentation comments in the public header file. check-in: 772dcb08 user: mistachkin tags: trunk
