26 check-ins using file src/sqliteInt.h version 525c061a

2017-01-25
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
21:12
Experimental changes to permit a VFS to directly override the initial page size. (Leaf check-in: 64131724 user: mistachkin tags: pagePerSector)
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)
00:11
Fix an initialized variable in kvtest. (check-in: ed62c5a6 user: drh tags: trunk)
2017-01-21
21:47
A better implementation of the moveto-neighbor optimization that checks for nearby rows on adjacent pages. (Closed-Leaf check-in: 2c4ecb85 user: drh tags: btree-moveto-neighbor)
16:54
B-tree optimization: When seeking on a rowid table that has already been positioned, check to see if the new row happens to be the next row on the same leaf page. That is a reasonably common case, and if it is true it avoids a full binary search. (check-in: 8e5cfb20 user: drh tags: btree-moveto-neighbor)
16:27
Change sqlite3_blob_reopen() to call sqlite3VdbeExec() directly rather than going through sqlite3_step(). Performance enhancement. (check-in: 347df3c1 user: drh tags: trunk)
16:21
Fix problems in the previous commit. (Leaf check-in: 74ad80eb user: dan tags: trigger-trace)
15:58
Add extra (somewhat inefficient) trace callbacks for triggers if SQLITE_TRACE_TRIGGER is defined. (check-in: ffda1d1e user: dan tags: trigger-trace)
15:55
In the kvtest.c test utility, reuse the buffer into which blobs are read, rather than reallocating it for each row. This is a closer match to how other test programs work, and thus provides a better comparison. (check-in: 0d1ad13a user: drh tags: trunk)
15:30
A proof-of-concept for running sqlite3_blob_open() without using OP_Column when operating on a pure key/value table. This demo does not include any corrupt database checking. Uses about 3% fewer CPU cycles on a key/value performance test. (Leaf check-in: 4cda3b30 user: drh tags: kv-access-opt-demo)
14:11
Remove an unnecessary sqlite3_bind_int64() call from sqlite3_blob_open(). Also other minor refactoring of the sqlite3_blob implementation. (check-in: 9d197a53 user: drh tags: trunk)
2017-01-20
20:43
Minor performance optimization and size reduction to the accessPayload() routine in btree.c. (check-in: 264e5c10 user: drh tags: trunk)
16:47
Fix a typo in the help message for kvtest. (check-in: 8971d98f user: dan tags: trunk)
16:46
Add option "--stats" to test program kvtest. Specifying --stats causes kvtest to output information similar to the shell tool option of the same name. (check-in: 90291327 user: dan tags: trunk)
16:09
Get the "--testset rtree" option working on speedtest1. Add the --rtree, --lookaside, and --clang options to the speed-check.sh script. (check-in: 87b640c8 user: drh tags: trunk)
00:40
Minor performance optimizations to sqlite3_blob_open() and sqlite3_blob_reopen(). (check-in: 52a61967 user: drh tags: trunk)
2017-01-19
21:20
If compiled with SQLITE_INLINE_MEMCPY, all memcpy() calls are replaced with in-line code. With that change, cachegrind shows which memcpy() calls are taking the most time. This is a performance-measurement hack only and is not for production use. (check-in: 9ed38521 user: drh tags: trunk)
