| 20:28 | Simplifications and performance optimizations for the RTree extension. (check-in: 04a333f5fa user: drh tags: trunk) | |
| 20:04 | Drop support for the view-scan optimization as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: 796a65fa61 user: drh tags: branch-3.28) | |
| 19:51 | Drop support for the view-scan optimization (check-in [609fbb94b8f01d67]) as it was causing multiple performance regressions. In its place, reduce the estimated row count for DISTINCT subsqueries by a factor of 8. (check-in: f911f1c497 user: drh tags: trunk) | |
| 19:27 | Minor simplification to the DISTINCT output row count change. (Closed-Leaf check-in: 0738386d7c user: drh tags: rethink-viewscan) | |
| 19:00 | Do not reduce subquery output row count estimates due to DISTINCT until after the decision of whether or not to use an index for ORDER BY has been made. (check-in: 27390051e8 user: drh tags: rethink-viewscan) | |
| 18:36 | Allow expressions like "<tbl>.rowid" to refer to implicit rowid columns of tables in nested FROM clauses. (check-in: 59a1bbc69f user: dan tags: nested-from-rowid-expansion) | |
| 16:15 | Experimental: Assume that a DISTINCT clause on a subquery reduces the number of rows returned by that subquery by a factor of 8. (check-in: 5a940e47d5 user: drh tags: rethink-viewscan) | |
| 14:06 | The view-scan optimization was added to enhance the performance of one specific query, but it causes performance regressions on a host of others. Disable it (at least temporarily) in order to try to find an alternative way of fixing the one specific query that it was created to fix - an alternative way that does not cause performance problems for other unrelated queries. (check-in: d9625a9eaf user: drh tags: rethink-viewscan) | |
| 10:27 | Do not try to convert a double into an unsigned 64-bit integer, as that does not work on all platforms. A double can only be converted into a signed 64-bit integer. (check-in: 4ce5a03e74 user: drh tags: branch-3.43) | |
| 10:24 | Do not try to convert a double into an unsigned 64-bit integer, as that does not work on all platforms. A double can only be converted into a signed 64-bit integer. This is a fix for the problem reported in forum post 9f6db917e1c05d40. (check-in: ce33904641 user: drh tags: trunk) | |

| 20:56 | Tests for java versions of Fts5ExtensionApi.xSetAuxdata() and xGetAuxdata(). (check-in: 858fa236f8 user: dan tags: trunk) | |
| 20:02 | JNI: move XTokenizeCallback interface out of the Fts5 object - that level of indirection is a holdover from when those classes were in the core package. (check-in: 385ec08570 user: stephan tags: trunk) | |
| 20:01 | Add a few more tests for Fts5ExtensionApi methods. (check-in: 4ce2a7e8ed user: dan tags: trunk) | |
| 17:42 | Add a test for the java version of Fts5ExtensionApi.xRowid(). (check-in: 227facf879 user: dan tags: trunk) | |
| 16:45 | According to forum post 9f6db917e1, older MSVC compilers are unable to convert a double directly into an unsigned long long int, but must first go through a signed long long int. Work around this by restricting the range of doubles that are converted into long long integers so that only the lower 63 bits are used. (Closed-Leaf check-in: 0ab05871ba user: drh tags: legacy-msvc-workaround) | |
| 16:02 | Document the use of OPFLAG_ISNOOP as the P2 argument on OP_Delete. No functional code changes. (check-in: d88f41b2cf user: drh tags: trunk) | |
| 14:05 | Avoid a segfault in test program showdb.c that could occur when analyzing a corrupt db. (check-in: 6bf3e90687 user: dan tags: trunk) | |
| 13:10 | Improve the sqlite3IntFloatCompare() routine so that it is testable. (check-in: bb221381fa user: drh tags: trunk) | |
| 10:46 | Do not set the global bUseLongDouble flag based purely on sizeof(long double) being more than 8. That is a necessary but not sufficient condition to use the long double routines. Instead, do a run-time test to verify that long double really does provide extra precision. (check-in: aa999d490b user: drh tags: trunk) | |
| 01:46 | Reduce the number of calls to sqlite3_mprintf() made by RTree. (Closed-Leaf check-in: f158b7d491 user: drh tags: rtree-performance) | |
|

| 21:32 | JNI: enable the fts5-customization bits by default but elide them from the docs until it's clearer where they're headed. Unrelated minor doc tweaks. (check-in: 21adb1aef2 user: stephan tags: trunk) | |
| 20:35 | Improved comments on the hasHighPrecisionDouble() routine. No changes to the underlying code. (Closed-Leaf check-in: 810c635ce0 user: drh tags: runtime-longdouble-test) | |
| 20:06 | Determine at start time whether or not the underlying hardware supports high-precision long double computations. (check-in: 9a854b9196 user: drh tags: runtime-longdouble-test) | |
| 17:30 | Omit the Reinsert algorithm from RTree. This causes most benchmarks to run faster, at the expense of having a slightly less dense and hence larger index (example: 33 entries/node versus 34 entries/node). (check-in: b3049a1d3d user: drh tags: rtree-performance) | |
| 17:16 | Doc corrections for the previous checkin. (check-in: 9ea0a9f39d user: stephan tags: trunk) | |
| 17:11 | Add JNI sqlite3_prepare_multi(), based on feedback. (check-in: fa1c153472 user: stephan tags: trunk) | |
| 14:07 | Performance optimization to cellContains() in RTREE. (check-in: 43cde22bf3 user: drh tags: rtree-performance) | |
| 13:12 | In the ChooseLeaf algorithm of RTREE, do an initial pass through the cells of a node looking for solutions that involve no cell enlargement. Only look for the minimum cell enlargement if the enlargement is non-zero for all cells. This results in a performance improvement by reducing the number of calls to cellUnion(). (check-in: 59f0e239d1 user: drh tags: rtree-performance) | |
| 12:06 | Reduce the number of calls to cellArea() in the ChooseLeaf() algorithm of rtree. (check-in: c633fe6be0 user: drh tags: rtree-performance) | |
| 11:36 | Remove unused variable from the ChooseLeaf algorithm in r-tree. (check-in: fb2e4a8067 user: drh tags: rtree-performance) | |
| 11:24 | Replace an if() condition in fts5 that is always true with an assert(). (check-in: 2170312c8d user: dan tags: trunk) | |

| 23:21 | CLI .import to accept EOF in lieu of record terminator on last field of CSV (with multiple field records), per RFC 4180. forum post 5b21c25bdfa (check-in: 6f7842f577 user: larrybr tags: trunk) | |
| 23:11 | Fix a use-after-free error in fts5 that could occur when querying the "rank" column immediately after another connection changes its definition. (check-in: dfc42411e6 user: drh tags: branch-3.43) | |
| 18:36 | Fix a use-after-free error in fts5 that could occur when querying the "rank" column immediately after another connection changes its definition. forum post a2dd636330. (check-in: cb54c2da52 user: dan tags: trunk) | |
| 17:49 | Clarify some metrics output in Tester1.java. (check-in: 4ae7199a82 user: stephan tags: trunk) | |
| 17:06 | Re-add the fts5 decls to sqlite3-jni.h, removed in a rebuild without fts5 enabled. Need a better solution for this problem. (check-in: 6f269790a0 user: stephan tags: trunk) | |
| 17:03 | Rename JNI sqlite3_errmsg() to sqlite3_errmsg16() for overall constency with the text()/text16() family of functions. (check-in: c4a8d8a571 user: stephan tags: trunk) | |
| 16:33 | JNI readme fix. (check-in: 7dde000efc user: stephan tags: trunk) | |
| 14:36 | 64-bit builds on Windows default to using UTF-8 output (as if the -utf8 command-line option had been specified.) 32-bit builds continue to use Windows code pages. There is also a new -no-utf8 command-line option to force the use of legacy code pages. (check-in: d8c7560e88 user: drh tags: trunk) | |
| 14:09 | Show the "(utf8)" tag on the CLI banner in Windows if in UTF8 mode. (Closed-Leaf check-in: 822699a4d9 user: drh tags: cli-utf8) | |
|
2023-09-11

| 10:56 | Roll back [84e38341aeab] because a direct pointer comparison is ill-advised when the client-data string is dynamically allocated. (Closed-Leaf check-in: 7b884832b7 user: stephan tags: db-client-data) | |

| 11:20 | In the JNI build, emit a reminder to not check in the javac-generated sqlite3-jni.h when FTS5 is disabled because changes in that feature flag result in unnecessary and large diffs in checked-in generated code. (Closed-Leaf check-in: caceb52fb5 user: stephan tags: jni-client-data) | |
| 07:52 | Disable FTS5 in the JNI build by default until it can be thoroughly tested. This is mainly so that the public-facing javadoc does not include it. (check-in: 6f25f02b70 user: stephan tags: jni-client-data) | |
