In sqlite_stat1, revert the number of rows to the average, not adjusted for the maximum. Instead add "uneven=NNN" where NNN is a multiplier to apply to the average to get the maximum. "uneven" is only reported if NNN is 10 or more. Also add the "slow" argument is the maximum number of rows reported by a full equality match is so large that a table scan seems likely to be faster. (check-in: 41773fa7 user: drh tags: enhanced-stat1)

Enhance console_io to permit emits limited in various ways, such as valid UTF-8, upto control chars, or with counted limits, all getting away from 0-termination as the sole limit. In CLI, use this capability to avoid certain emit-chars-singly procedures that were breaking up UTF-8 characters. This fixes broken json mode output (on Windows) and (maybe) C-literal-like emits.

Fix malf with redirected input due to bad assumption that stdin is a console in the fgets() replacement. (check-in: 79d1f2c1 user: larrybr tags: console-io-lib)
06:20
Pervasive changes to console_io.{c,h} in support of simplifying ubiquitous emit ops in shell, and to get better control of console streams that might be opened only via .read or .output commands. Changes to shell to use {s,o,e}put{f,z}(...) calls for initial testing, but this check-in has few such conversions so that most will be in a separate check-in. Many renames to better follow recent coding convention. This code seems to be working, but has not been tested on difficult platforms or with multiple console hosts yet. So it is a WIP.

Add the SQLITE_RESULT_SUBTYPE flag for application-defined functions. Add the -DSQLITE_STRICT_SUBTYPE=1 compile-time option that raises an error if any function invokes sqlite3_result_subtype() without the SQLITE_RESULT_SUBTYPE flag.

Properly close a handle. Use a putatively effective runtime test for UTF-8 console I/O capability. (This makes the version test useful mainly for avoiding a warning that UTF-8 console I/O could not be setup.) (check-in: dc91eb91 user: larrybr tags: win-utf8-io-split)
00:24
Condition default UTF-8 console I/O for Windows builds on OS version 10 or more. This is to accomodate an IsValidCodePage() API which may happily report CP_UTF8 as a valid code page when the stock console cannot, in fact, do UTF-8 I/O. (check-in: 6b9b2a88 user: larrybr tags: win-utf8-io-split)

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.

09:53
An initial attempt at protecting the JNI global state via mutexes at the C level instead of relying on Java's synchronized keyword. It seems to work but increases the run time of the single-threaded SQLTester batch by roughly 3 times. (Correction: it was just run on a slower machine. Cursory testing suggests that runtime performance hit might be, but likely isn't, as high as 10%.) (check-in: c64e6a52 user: stephan tags: jni-threading)

11:12
Up until version 3.42.0, there was a bug in json_valid() such that it would return False (0) for a NULL input. That bug is fixed in 3.42.0.

Document that auto-extensions registered via JNI will fail if they open a db (to avoid triggering an endless loop in the auto-extensions). Discover the hard way that JDKv19 creates different mangled JNI names for some functions than JDKv8. Start reformatting much of the JNI API decls in prep for making them even longer.

Move the test command body's trim() back into the TestScript class (to simplify Command-level code) but do it after double-verbose has had the chance to emit it as-is (so that debug output is not mangled by the trim). (check-in: f15ecb68 user: stephan tags: jni)
16:56
Tweak the SQLTester --verbose and double-verbose output a bit for legibility. (check-in: 46b79afa user: stephan tags: jni)
16:29
Strip --oom commands from SQLTester input since (A) we can't currently do anything with them and (B) they can appear as body content of --testcase commands and the current parser cannot deal with that. If --verbose is provided once, emit the name and args of each command as it's run. If --verbose is used twice or more, also emit the command's body text, if any. (check-in: 0770e846 user: stephan tags: jni)
16:03
Update the definition of "special characters" for the SQLTester and correct the code to match it. (check-in: 217f6e0c user: stephan tags: jni)
15:46
Extend TestScript to be able to report why it should be skipped. Expand the test-skipping rules to account for the current spec doc. Add the {} empty-string case to the spec doc. (check-in: 4fcc8cb0 user: stephan tags: jni)
14:47
Add a test for the --null command. (check-in: 83ac815d user: stephan tags: jni)
14:43
Extend SQLTester glob support with '#'. (check-in: 756ef83f user: stephan tags: jni)
14:24
Implement the SQLTester's result escaping rules. (check-in: 61bb9508 user: stephan tags: jni)
13:51
Add --json and --json-block SQLTester commands. (check-in: 478129d9 user: stephan tags: jni)
13:16
Add SQLTester --tableresult command. (check-in: 8c5b6d89 user: stephan tags: jni)
12:05
Clean up the SQLTester output a bit by using the module name, instead of filename, where appropriate. (check-in: 5323e4fd user: stephan tags: jni)
11:10
Document SQLTester's --print command and add some argument validation to it. (check-in: ab9c945b user: stephan tags: jni)
11:05
Rework how SQLTester's Command objects are dispatched and how TestScript stores its command entries. (check-in: f929f1f7 user: stephan tags: jni)
09:56
Some minor tweaks in SQLTester in prep for larger refactoring. (check-in: 1d93f93a user: stephan tags: jni)
2023-08-08
22:10
Remove the current-statement tracking from the JNI internals because it will break down in the face of client-side mixed-mode native/java code, e.g. in cases like SQLTester. This makes tracing of sqlite3_stmt a micron slower but also reliably correct. (check-in: 4c0ec89d user: stephan tags: jni)
21:22
Adapt JNI build to be buildable with or without SQLTester. (check-in: adae7d78 user: stephan tags: jni)
21:05
Add SQLTester dup() and dup_count() UDFs. Correct arg handling of the --run command. (check-in: 0dba3073 user: stephan tags: jni)
20:41
Correct --result arg count check and add infrastructure to let us add custom C-side behavior to SQLTester via an auto extension. (check-in: bb832170 user: stephan tags: jni)
20:15
If SQLTester now treats a no-args --result as comparing against an empty string. (check-in: 49005ca5 user: stephan tags: jni)
20:02
Add glob/notglob commands to SQLTester and complete the interrupted-midway impls of the strglob() and strlike() JNI bindings. (check-in: 4ba98ec0 user: stephan tags: jni)
19:20
When SQLTester hits an unknown command, emit a warning and skip the rest of that script instead of aborting the whole run, per /chat discussion. Reduce verbosity a bit. (check-in: 3e78d22d user: stephan tags: jni)
17:36
Minor cleanups in sqlite3Int.h. By reordering some fields in the Parse object, it packs more tightly and uses less memory and less CPU to initialize. (check-in: aa6de539 user: drh tags: trunk)
16:53
Fix an issue in the amalgamation generator in which it was not correctly expanding the SQLite version in the header comment. (check-in: 293f6191 user: drh tags: trunk)
14:58
Correct the spacing output of multi-select SQL blocks for SQLTester --result. (check-in: 8d98645a user: stephan tags: jni)
14:49
Updates to the test script interpreter spec: Rather than failing immediately upon encountering an incompatibility, simply abandon the rest of that particular input file. (check-in: d2c99b96 user: drh tags: jni)
14:40
A number of baby steps for SQLTester.java. It can now handle basic --result cases. (check-in: 0404f688 user: stephan tags: jni)
14:25
Add a few words of clarification on how the SQLite Test Script Interpreter should be initialized to start each test script. (check-in: 3aa2b5a5 user: drh tags: jni)
13:05
Correct JNI sqlite3_prepare() to emit a null stmt handle when the C counterpart succeeds but results in a NULL pointer. (check-in: 94628f88 user: stephan tags: jni)
11:46
Implement the new/open/close SQLTester commands. (check-in: dc823bf0 user: stephan tags: jni)
11:46
Add a JNI-layer sqlite3.toString() for debugging. (check-in: 45669164 user: stephan tags: jni)
10:58
Bind sqlite3_strlike/strglob() to JNI. (check-in: eb5440f7 user: stephan tags: jni)
09:45
SQLTester: add print command and improve argument error reporting infrastructure. (check-in: 1b6e84f6 user: stephan tags: jni)
00:59
Add missing license header. Minor cleanups in SQLTester. (check-in: 5be50fd5 user: stephan tags: jni)
00:37
Rework SQLTester dispatching and add stub impls for several commmands. (check-in: 9e61af75 user: stephan tags: jni)
2023-08-07
23:59
Add command dispatcher to SQLTester. (check-in: e0a06931 user: stephan tags: jni)
23:04
SQLTester now ignores tests which contain constructs specified in the spec doc. (check-in: ecaeee65 user: stephan tags: jni)
22:32
SQLTester can now split a test script into a series of individual commands. (check-in: d3d1accc user: stephan tags: jni)
22:02
SQLTester can now read a script and strip it of all noise content. (check-in: 59bd3928 user: stephan tags: jni)
21:04
Initial skeleton for adding an SQL-driven test script interpreter for the JNI bindings. (check-in: 2aa8f0ed user: stephan tags: jni)
17:09
Enhance sqlite3_vtab_nochange() so that it works with "UPDATE ... FROM ..." statements. Use this to allow some updates on fts5 contentless-delete tables. (check-in: 27ff86e4 user: dan tags: trunk)
16:15
Changes so that sqlite3_vtab_nochange() works with "UPDATE ... FROM...". Use this to allow UPDATE on a contentless fts5 table if new values are supplied for all indexed columns. (Closed-Leaf check-in: 16cd2161 user: dan tags: fts5-contentless-delete)
11:18
When converting a Java exception to a db error message, use Throwable.toString() instead of getMessage() so that the exception type's name is included. More internal API renaming for consistency. (check-in: 2d44720d user: stephan tags: jni)
10:59
Lots of JNI internal API renaming, for consistency, and moving-around of utility functions. Make it safe for more callback types to throw. (check-in: 9a494394 user: stephan tags: jni)
10:01
JNI API renaming to better match the C API. (check-in: 6e0bd03d user: stephan tags: jni)
09:44
Rename fts5_api pContext parameters to pUserData, per /chat discussion. This is a cosmetic change made to reduce confusion between those parameters and the two other context-type parameters in that API. (check-in: 2ca064d8 user: stephan tags: trunk)
01:06
Make sqlite3_stmt() Java ctor private - it's only constructed from JNI code. (check-in: ce82c42f user: stephan tags: jni)
00:29
Minor internal cleanups and additional test metrics. (check-in: fa0a6b6e user: stephan tags: jni)
00:06
Bind the auto-extension APIs to JNI. (check-in: 746a5fa0 user: stephan tags: jni)
2023-08-06
22:09
Rework the sqlite3_open(_v2)() order of operations so that pending auto-extension support can get ahold of the open-time Java state despite the Java/C (sqlite3*) binding not having yet been established. (check-in: 34da294a user: stephan tags: jni)
21:29
Completely rework how the JNI sqlite3_open(_v2) and sqlite3_prepare(_vN)() bindings deal with output pointers to give the JNI side full control over the origin of db and stmt handles (necessary for solving chicken/egg situations in auto-extensions and prepare-time trace). Lots of adjacent internal API renaming. (check-in: 644999ca user: stephan tags: jni)
20:01
Start adding JNI-side support for auto extensions, but hit a brick wall which requires slightly awkward semantics changes in the JNI bindings for sqlite3_open(_v2)() to resolve, so stash this #if'd out for the time being. (check-in: 77a32d23 user: stephan tags: jni)
15:01
Doc cleanups. (check-in: 5f56b007 user: stephan tags: jni)
14:19
Bind sqlite3_config() to JNI for call variants taking (int,int*) and (int,const char *) variadic arguments. (check-in: 6119289d user: stephan tags: jni)
13:02
JNI-internal cleanups and API renaming. Add a C-side java-string-to-utf8 conversion. (check-in: 672d8579 user: stephan tags: jni)
11:05
Remove doc outdated warning about sqlite3_trace_v2() JNI binding being incompatible with MUTF-8. Use new to-string capability to simplify Fts5ExtensionApi::xColumnText() JNI binding. (check-in: ebcfc237 user: stephan tags: jni)
10:49
Add a way to convert from standard UTF-8 to a Java string (JNI lacks this capability). (check-in: 07dd082c user: stephan tags: jni)
10:14
Bind sqlite3_db_filename() and (closely related) (A) add many more docs about the UTF-8/MUTF-8 discrepancy (B) start adding internals to enable us to perform the standard-UTF-8-to-Java conversion from C. (check-in: 586720fa user: stephan tags: jni)
2023-08-05
22:41
Bind sqlite3_set_authorizer() to JNI. (check-in: e0fa0313 user: stephan tags: jni)
21:35
Refactor the per-JNIEnv cache from a fixed-size static array to a linked list of dynamically-allocated entries. Uncache all per-db state (which is necessarily JNIEnv-specific) when the corresponding JNIEnv is uncached. (check-in: 9dd8b784 user: stephan tags: jni)
20:19
Add SQLite3Jni.uncacheJniEnv(), a way for Java threads to clear their thread-specific cached state from the JNI bindings when they're about to terminate (or are otherwise done using the library). (check-in: 7468f876 user: stephan tags: jni)
19:20
In the JNI docs, note that the sizeof SQLITE_TRANSIENT and SQLITE_STATIC should ideally be the same as the platform's pointer size. (check-in: 7d4ac44e user: stephan tags: jni)
19:15
Tiny doc typo fixes from forum post 31eb707250. No code changes. (check-in: 8ede5008 user: stephan tags: trunk)
12:48
JNI internal refactoring and cleanups. (check-in: 7397973a user: stephan tags: jni)
11:16
Bind Fts5ExtensionApi::xUserData() to JNI and extend xCreateFunction() to accept that argument. In test code, use assert() instead of exceptions if assert() is enabled so that test failures (exceptions) thrown via callbacks do not get suppressed (which they otherwise necessarily are to avoid crashing the host app). (check-in: e4383737 user: stephan tags: jni)
04:30
Add missing Fts5PhraseIter.java to the build. (check-in: 96281ad0 user: stephan tags: jni)
04:23
Bind fts5_api::xCreateFunction() to JNI and demonstrate it with a test. (check-in: c653bf16 user: stephan tags: jni)
01:28
Start adding fts5_api to JNI. (check-in: 14d18fe9 user: stephan tags: jni)
00:40
Bind the remaining Fts5ExtensionApi methods to JNI, noting that all are completely untested because the higher-level bits needed to do so are still missing. (check-in: 23383c1d user: stephan tags: jni)
2023-08-04
16:01
In the opfs-sahpool VFS's importDb() and exportFile() methods, throw if the actually-wrote/read amounts differ from the expected-to-write/read amounts, per feedback in forum post a4122e986f. (check-in: a617ebf4 user: stephan tags: trunk)
15:38
More work on the JNI binding of fts5 customization (still a long ways to go). (check-in: 1a246fd2 user: stephan tags: jni)
13:29
Merge the json_remove() bug fix from trunk into the bedrock branch. (check-in: a8872aa5 user: drh tags: bedrock)
13:27
Eliminate code duplication in the two JNI tester classes. (check-in: 63e7bbe3 user: stephan tags: jni)
13:24
Merge the json_remove() bug fix from trunk into the wal2 branch. (check-in: e6c066ca user: drh tags: wal2)
13:19
Fix a bug in the jsonLookup() routine used to search JSON. Bug was introduced by the recent (unreleased) JSON caching enhancements check-in [a4c1af616e672a0d] merged into trunk at [df099ad713011b67]. (check-in: ba7a66db user: drh tags: trunk)
13:03
FTS-related JNI refactoring. Move FTS-specific tests into their own class and dynamically load it, if possible, from the main test app. (check-in: b7a8428f user: stephan tags: jni)
12:44
More work towards binding FTS5 customization to JNI. Add Fts*.java files missing from previous checkin. (check-in: 91263178 user: stephan tags: jni)
11:10
Change comment on Fts5ExtensionApi.iVersion from "always set to 3" to "always set to 2". (check-in: b7de399c user: dan tags: trunk)
11:08
Start including fts5 customization bits into JNI, but it's far from functional. (check-in: abaf5edd user: stephan tags: jni)
09:53
Improve internal error handling in the JNI create_function() impl. (check-in: 2c88390f user: stephan tags: jni)
08:45
Resolve the timing/ordering issue of a JS-to-WASM-converted xDestroy() function being uninstalled from WASM right before the underlying native call tries to call it. This has been a long-unnoticed bug which appears only when removing such functions or replacing them. (check-in: 031c9a76 user: stephan tags: trunk)
08:41
Part 2 of the fix from [a0f808363318c00fd1db78b]. (check-in: 5c310422 user: stephan tags: trunk)
08:39
More work towards fts5 customzation in JS. (Leaf check-in: ce2a65d8 user: stephan tags: wasm-fts5)
2023-08-03
23:26
Merge the latest trunk enhancements into the bedrock branch. (check-in: 877ffece user: drh tags: bedrock)
23:22
Merge the latest trunk enhancements into the wal2 branch. (check-in: 6fa71e11 user: drh tags: wal2)
22:43
Minor internal cleanups in the JS-side fts5 cleanup steps. (check-in: 2666f52e user: stephan tags: wasm-fts5)
21:14
Retain all xDestroy method WASM proxies created for fts5_api::xCreateFunction() until the db is closed, then free them all at once. (check-in: f4b9743a user: stephan tags: wasm-fts5)
20:45
Rework the fts5 db-close cleanup to avoid that fts5 internally calls a just-unbound-from-wasm xDestroy() method. There is still work to do here to cover the case of fts5 functions being replaced (in which all xDestroy methods have to be retained until the db is closed). (check-in: 795f2242 user: stephan tags: wasm-fts5)
20:02
Part 2 of the fix from [a0f808363318c00fd1db78b]. (check-in: ce0674b1 user: stephan tags: wasm-fts5)
18:46
Resolve the timing/ordering issue of a JS-to-WASM-converted xDestroy() function being uninstalled from WASM right before the underlying native call tries to call it. This has been a long-unnoticed bug which appears only when removing such functions or replacing then. (check-in: a0f80836 user: stephan tags: wasm-fts5)
18:14
Fix harmless scan-build warnings. (check-in: 65a8716d user: drh tags: trunk)
16:22
Fix a discrepancy between sqlite3_values_to_js() and its API docs/intended behavior. (check-in: 7b85c68f user: stephan tags: trunk)
16:21
More infrastructure towards binding FTS5 customization support to WASM. (check-in: 163e3e44 user: stephan tags: wasm-fts5)
16:02
Fix a discrepancy between sqlite3_values_to_js() and its API docs/intended behavior. (check-in: 16658b3c user: stephan tags: wasm-fts5)
13:30
Fix build problems associated with SQLITE_OMIT_WSD and SQLITE_OMIT_TRIGGER. (check-in: de031a5e user: drh tags: trunk)
13:07
Fix a test case whose value changes under the no_optimization permutation due to the recent change to add the ability for SQLITE_TESTCTRL_OPTIMIZATION to disable one-pass. (check-in: 976e39c6 user: drh tags: trunk)
12:41
Unix builds now assume the presence of nanosleep() in the standard library. The -DHAVE_NANOSLEEP=0 compile-time option can be used to build on systems (if any still exist) where this is not the case. (check-in: 779d5dc8 user: drh tags: trunk)
07:20
Initial work on exposing the FTS5 APIs to wasm, per request in the forum. This builds and loads the structs into JS but is completely untested. (check-in: 52c8b73a user: stephan tags: wasm-fts5)
2023-08-02
18:20
If a query has an ORDER BY clause that only refers to result columns of the left-most table and the left most table is a MATERIALIZED common table expresion, then attempt to push the ORDER BY clause down into the subquery. (Leaf check-in: 8e7a70b2 user: drh tags: order-by-push-down)
17:29
More JNI-internal docs. Correct handling of a Java exception if a trace callback throws. (check-in: 306b269a user: stephan tags: jni)
17:20
Internal doc additions in the JNI bits. (check-in: b5664364 user: stephan tags: jni)
16:06
Performance optimization for JSON rendering logic. (check-in: ea0b9aec user: drh tags: trunk)
13:45
Remove an unreachable branch in the ascii-to-floating-point conversion that was added by [e989a37ff9d5b52e]. (check-in: c4347e44 user: drh tags: trunk)
13:38
Stricter enforcement of the idea that a MATERIALIZED common table expression is an optimization fence. (check-in: 354425f8 user: drh tags: trunk)
13:29
Remove a condition from query flattening that is now taken care of by the caller. Factor out the reverse_unordered_selects processing from the main loop of sqlite3WhereBegin() for performance. (Closed-Leaf check-in: f068f105 user: drh tags: materialize-order-by)
12:39
Simplify the select.c logic that enforces the optimization fence around a MATERIALIZED common table expression. Do not allow the reverse_unordered_selects setting to affect a fenced CTE that itself has an ORDER BY clause. (check-in: 165b9bda user: drh tags: materialize-order-by)
11:06
Never flatten a CTE that is labeled MATERIALIZED. This is really something of a bug fix because the documentation says that a MATERIALIZED CTE is an optimization barrier. (check-in: b7ef9796 user: drh tags: materialize-order-by)
00:09
When a query is inside an AS MATERIALIZED CTE, do not attempt the omit-ORDER-BY optimization. If the developer specifies MATERIALIZED, that means he wants the sort to actually happen. (check-in: aa769ee7 user: drh tags: materialize-order-by)
2023-08-01
19:10
Avoid ASAN warnings when converting over-sized long double values into double. (check-in: e989a37f user: drh tags: trunk)
16:41
Filter the wasmfs-specific JS module result type check out of non-wasmfs builds. (check-in: ef7c1210 user: stephan tags: trunk)
16:38
Fix part 2 of 2 for /fiddle: a make deps problem which caused fiddle to load but fail to run when sqlite3.c was missing. (check-in: 6011bc26 user: stephan tags: trunk)
16:17
Fix part 1 of 2 for /fiddle not running: build flags which were renamed during refactoring. (check-in: 214ffeef user: stephan tags: trunk)
11:03
Fix an assert() in fts5_index.c that might fail when dealing with corrupt records. (check-in: aa55c83f user: dan tags: trunk)
10:19
More docs for the Java side of the JNI bindings. (check-in: d8e9bcee user: stephan tags: jni)
09:44
Internal exception-handling cleanups in the JNI bindings. (check-in: 057b1d4f user: stephan tags: jni)
08:48
Minor JNI-related doc tweaks and code re-ordering. (check-in: b663b27e user: stephan tags: jni)
01:07
Remove redundant comparison operator. (check-in: 01898432 user: drh tags: trunk)
00:34
Restore part of the UPDATE one-pass optimization that was removed by check-in [2c56b984a0bd3be5]: only disable one-pass if the WHERE clause contains a subquery. Allow subqueries in the SET expressions. Fix for performance problem reported by forum post 8ab195fd44e75ed0. (check-in: 42916af9 user: drh tags: trunk)
2023-07-31
22:03
Restrict the new column cache to table-btree, which is the common case anyhow. That way, writes to indexes do not need to clear the column cache. (check-in: 659284ab user: drh tags: trunk)
20:02
The original column-cache implementation from check-in [ab1edcc7fedcf279] (merged to trunk at [771fe35074b50b8d]) is unsound. This check-in fixes the issue. Had to give back a little performance, the optimization is still a overall win. (check-in: ec95e970 user: drh tags: trunk)
17:39
Add bit to sqlite3_test_control(SQLITE_TESTCTRL_OPTIMIZATIONS) that will disable the one-pass optimizating in DELETE and UPDATE. (check-in: 22f6dd5c user: drh tags: trunk)
17:20
Improved debug tracking of the Parse.nQueryLoop value. (check-in: 4a8a1749 user: drh tags: trunk)
13:52
Experimentally change the JNI sqlite3_trace_v2() callback type to have more convenient access to the current Java-side sqlite3_stmt at the cost of some uncomfortably fiddly current-statement tracking in the JNI layer. Subject to change. (check-in: 459db332 user: stephan tags: jni)
12:10
Add some JNI-internal metrics, accessible via passing -v when running Tester1.java. Document an OpenJDK bug which leads to incorrect -Xlint:jni warnings. (check-in: a5d68a6b user: stephan tags: jni)
10:55
Correct a mis-cast in the JNI wrapper which just happened to accidentally work. Update JNI binding of sqlite3_context_db_handle() to return the bound-at-open() db instance instead of a new/temp proxy object. (check-in: 9faca5d9 user: stephan tags: jni)
10:42
Add another test for JNI-bound scalar UDFs. (check-in: 8b322d92 user: stephan tags: jni)
10:22
Update some internal docs for the past two checkins. Add a way to dump out some debug info about the current JNI environment. (check-in: ac9b8bb1 user: stephan tags: jni)
10:08
Refactor the busy-handler-specific JNI hook type to use the generic hook type. (check-in: d9efdc6d user: stephan tags: jni)
09:45
Refactor the collation-specific JNI hook type to use the generic hook type. (check-in: 02c1d3b6 user: stephan tags: jni)
09:28
Internal JNI doc tweaks. (check-in: f4aa2c82 user: stephan tags: jni)
07:15
Consolidate triplicated xDestroy()-calling code. Remove some unnecessary casts. (check-in: 24c0763d user: stephan tags: jni)
2023-07-30
18:41
Internal JNI API renaming. (check-in: fcfc0706 user: stephan tags: jni)
17:24
Internal JNI refactoring towards consolidating support for callbacks with and without finalizers. (check-in: 120983a5 user: stephan tags: jni)
13:47

CLI enhancements to facilitate SQLite core testing: (1) Add built-in functions strtod() and dtostr() that convert text to floating point and back using C-library routines. (2) Do not disable all of ".testctrl" without --unsafe-testing, but only those subcommands of .testctrl that are actually dangerous. (check-in: 669996a8 user: drh tags: trunk)

This is a failed attempt to optimize the usage of the page cache in sqlite3BtreeIndexMoveto() by deferring calls to sqlite3PagerUnref() for child pages of the btree until we are sure those pages will not be reused. The code does not work in two senses: (1) Many tests still fail. (2) The performance gain is less than 2 million cycles and does not seem worth the extra risk and complication.
