2015-10-16
17:31
Version 3.9.1 (check-in: 767c1727fe user: drh tags: release, branch-3.9, version-3.9.1)
15:56
Cherrypick the json form-feed fix, and other #ifdef and build script changes to address minor issues that came to light after the 3.9.0 release. Update the version number to 3.9.1. No logic changes except for the form-feed bug-fix in json1 (ticket [57eec374ae1d0a1d4a]). (check-in: 746fcd2fd4 user: drh tags: branch-3.9)
15:42
Fix the fuzzershell utility program so that it compiles with the amalgamation that includes JSON1 support. (check-in: d6fc616e4c user: drh tags: trunk)
15:35
Fix the JSON1 extension so that it does not depend on isdigit() and strtod() from the standard library when compiled into SQLite as part of the amalgamation. (check-in: bc9a9a60c3 user: drh tags: trunk)
15:16
Form-feed is not valid whitespace for json. Fix for ticket [57eec374ae1d0a1d] (check-in: 28957d6359 user: drh tags: trunk)
14:54
Have the sqlite3VdbeSerialType() function go ahead and compute the serial length as well, since it is always needed. This avoids unnecessary calls to sqlite3VdbeSerialTypeLen(). (check-in: 2ad72be124 user: drh tags: trunk)
14:23
Use a lookup table to compute the content length for serial types less than 128, for a 1.2% performance improvement. (check-in: 3395724814 user: drh tags: trunk)
13:50
Simplify the OP_Column logic slightly. One very small performance improvement added. (check-in: 0114b45dc2 user: drh tags: trunk)
12:53
OP_Column optimization: Do not check for an oversize row header unless the row header size is larger than the content available on the local page. (check-in: 8125b74cb4 user: drh tags: trunk)
12:39
Improved header comment on the tool/vdbe_profile.tcl script. No changes to code. (check-in: b17ad8fc04 user: drh tags: trunk)
03:34
Whenever two or more OP_Column opcodes on the same cursor occur in succession, try to reordering them so that the one that extracts the right-most column is first, so that it will warm up the row cache for all those that follow. This gives a small performance boost. (Leaf check-in: 08e8f04d12 user: drh tags: reorder-column-opcodes)
2015-10-15
21:30
Performance optimization for the OP_Column opcode. (check-in: 076be5474d user: drh tags: trunk)
21:13
Merge updates from trunk. (Leaf check-in: 4049368008 user: mistachkin tags: mutexInitIsInitReCheck)
21:12
Merge updates from trunk. (Leaf check-in: a447cf90dd user: mistachkin tags: mutexInitSimpleCmpSwap)
20:17
Experiments with an OP_Unpack opcode that extracts multiple columns from a record without caching. (Leaf check-in: 39ae92f5c6 user: drh tags: unpack-opcode)
19:21
Enhance the use of the column cache for UPDATE statements, making them more efficient for the case where a column is modified to be an expression of other unmodified columns. (check-in: 871e091df6 user: drh tags: trunk)
18:04
Add the OP_IntCopy opcode - an optimized version of OP_SCopy that only works for integer values. (check-in: 3a2f73a492 user: drh tags: trunk)
17:31
Optimization to the out2Prerelease() helper routine in the VDBE engine. (check-in: 79298fe8c4 user: drh tags: trunk)
17:21
Remove a superfluous conditional from the memory allocation initialization. (check-in: 9ccf8f8d35 user: drh tags: trunk)
16:20
Performance optimizations to the sqlite3MallocSize() by requiring the argument to always be non-NULL. (check-in: cb65989b07 user: drh tags: trunk)
15:28
Change sqlite3StatusSet() into sqlite3StatusHighwater() so that only the highwater mark is recorded. This gives a small size reduction and performance improvement. (check-in: 6422d223dd user: drh tags: trunk)
12:06
Make sure sqlite.h is not #included by itself. (check-in: a61880c223 user: drh tags: trunk)
07:44
Merge in the 3.9.0 changes from trunk. (check-in: 5c3a2a6ed6 user: drh tags: begin-concurrent)
2015-10-14
23:04
In the MSVC makefile, add LIBTCLPATH variable to make it easier to run tests when the Tcl library is not already present in the PATH. (check-in: 54127602b9 user: mistachkin tags: trunk)
22:46
In the MSVC makefile, make sure LDFLAGS is used for the tool executables as well. (check-in: 0a17ee49c6 user: mistachkin tags: trunk)
21:08
Tests and minor fixes to improve coverage of FTS5 code. (check-in: f4de6d450e user: dan tags: trunk)
20:34
Fix harmless compiler warnings. (check-in: 1c46c194a2 user: mistachkin tags: trunk)
20:09
Merge in all the 3.9.0 updates from trunk. (check-in: 2944414934 user: drh tags: cursor-hints)
20:03
Update makefiles to remove all uses of "awk" - to make building SQLite easier on Windows systems. The only requirements now are tclsh, a C compiler, and common file utilities. (check-in: 4bd0d43db7 user: drh tags: trunk)
20:01
Enable cross-compiling the various tool EXEs with MSVC. (check-in: 7d77233389 user: mistachkin tags: trunk)
19:52
Fixes to the JSON1 extension and its use by fuzzcheck to avoid problems when building DLLs. (check-in: 01d3ee7bbe user: drh tags: trunk)
19:44
Fix fuzzcheck.c so that it assumes that JSON1 is already compiled in and does not need to be initialized further. (Closed-Leaf check-in: ec00395835 user: drh tags: dll-build-fix)
18:45
Avoid exporting sqlite3_json_init() from amalgamation builds. (check-in: 8463f7e790 user: dan tags: dll-build-fix)
12:29
Version 3.9.0 (check-in: a721fc0d89 user: drh tags: trunk, release, version-3.9.0)

2015-10-13
20:42

22:20
Fix a couple harmless compiler warnings. (check-in: 7f896a971c user: mistachkin tags: trunk)
19:12
Further tweaks to improve fts5 prefix query performance. (check-in: 1c20c1c28b user: dan tags: trunk)
04:56
Change all references to 3.8.12 into 3.9.0. Comment changes only - no changes to code. (check-in: 6f2858f681 user: drh tags: trunk)
03:56
Remove AWK requirement from the MSVC batch build tool. (Closed-Leaf check-in: 6d9cdb931c user: mistachkin tags: omit-awk)
03:44
The TclKit batch tool should not download the TclKit SDK when the TCLKIT_NOSDK environment variable is set. (check-in: 7c5d583bac user: mistachkin tags: omit-awk)
2015-10-11
20:39
Detect and report circularly defined views even if the views have the columns defined in the CREATE VIEW statement. (check-in: 9ab9c8c6d7 user: drh tags: trunk)
20:08
Remove an unreachable branch in the query flattener substitution logic. (check-in: 46ee3453a3 user: drh tags: trunk)
19:46
Improved substitution logic in the query flattener. Saves code space, and (more importantly) works correctly with table-valued functions. (check-in: 3d0bd95e97 user: drh tags: trunk)
2015-10-10
23:39
Enhance TclKit batch tool (and MSVC makefile) to support targets that require the Tcl stub library. (check-in: bc6223b1d6 user: mistachkin tags: omit-awk)
