50 most recent check-ins related to "trunk"

2024-05-04
21:10
Add new sessions API sqlite3changegroup_add_change(). (Leaf check-in: 73647db1dd user: dan tags: changegroup-add-change)
16:50
Add test cases to test/in7.test. No code changes. (Leaf check-in: 8c3086f9fe user: dan tags: trunk)
15:10
Assume that an SQL function is able to return a subtype if any of its arguments are SQL functions that are able to return subtypes. This closes a corner-case hole in the patch at [ba789a7804ab96d8]. (check-in: b36d499e4c user: drh tags: trunk)
15:04
Assume that a function is able to return a subtype if either (1) it is itself marked with SQLITE_RESULT_SUBTYPE, or (2) one of its arguments is a function that is able to return a subtype. This check-in backs out the code changes from the previous two on this same branch, but keeps the test cases from the previous two. (Closed-Leaf check-in: f16b200f25 user: drh tags: func-rw-subtype)
2024-05-03
19:35
The coalesce(), ifnull(), and iif() functions pass through subtype values from their arguments, and hence need to have the SQLITE_RESULT_SUBTYPE flag set. (check-in: cdd1610c44 user: drh tags: func-rw-subtype)
2024-05-02
19:22
Fix a problem with queries that use "IN(...) ORDER BY ... NULLS LAST" or similar introduced by [d7648e21605a0b38]. (check-in: 26b2d9390f user: dan tags: trunk)
18:16
Avoid an assert failure accessible only when internal testing features are enabled. dbsqlfuzz crash-66abacda6bca6bd531e25595e8c8068e2c710326.txt. (check-in: fbc446daac user: dan tags: trunk)
17:46
Fix a case where the recovery extension might write uninitialized data to the recovered database. (check-in: 8519b4d039 user: dan tags: trunk)
14:48
Avoid an OP_Next in cases where an IN(...) query against a UNIQUE index may return at most 1 row. (check-in: d7648e2160 user: dan tags: trunk)
12:14
Fix the CREATE TABLE performance issue described by [forum:/forumpost/4cf69794d9dfff7c|forum thread 4cf69794d9dfff7c] in two different ways: (1) Omit the call to PRAGMA integrity_check('X') that was being done after CREATE TABLE "X" because the result was being ignored and the integrity_check was not doing anything other than burning CPU cycles. (2) Do not interpret the argument to PRAGMA integrity_check as a number if it is in fact a string that looks like a number. (check-in: 71f08b9122 user: drh tags: trunk)
12:00
Add a test case to the fix to PRAGMA integrity_check in the previous check-in. (Closed-Leaf check-in: 39a57b596d user: drh tags: faster-create)
11:51
Omit the OP_SqlExec to "PRAGMA integrity_check" added by [348fa7aaf7958b3f] because it is a no-op. Even if the integrity_check failes, the CREATE TABLE is stull successful. The OP_SqlExec just burns CPU cycles for no reason. (check-in: 532795acd1 user: drh tags: faster-create)
2024-05-01
19:48
Avoid an OP_Next in cases where an IN(...) query against a UNIQUE index may return at most 1 row. (Closed-Leaf check-in: 560f64157d user: dan tags: unique-in-opt)
16:25
Fix another problem in the recovery extension where a corrupt sqlite_schema table could lead to excessive memory consumption. (check-in: 1c7e33a8aa user: dan tags: trunk)
14:42
Fix a problem causing the recovery extension to use excessive memory and CPU time in some cases. (check-in: 8de85170d5 user: dan tags: trunk)
2024-04-30
19:34
Avoid 32-bit overflow when calculating ncycle for ".scanstats vm". (check-in: 2858efa06d user: dan tags: trunk)
2024-04-26
19:10
Fix issues in [/info/1e227ad9f413227f|LIMIT/OFFSET support for virtual tables]. The first problem was reported by [forum:/forumpost/c243b8f856|forum post c243b8f856]. That report prompted an enhancement to the generate_series() (also included in this merge) which in turn identified other similar issues. (check-in: 5f6c079d84 user: drh tags: trunk)
18:42
Internal JS doc touchups. No functional changes. (check-in: 626b997b4e user: stephan tags: trunk)
18:24
Additional internal docs in the wasm utilities. (check-in: 5a2245a9eb user: stephan tags: trunk)
18:13
Allow virtual table implementations to handle OFFSET but not LIMIT, but not LIMIT but not OFFSET. (Closed-Leaf check-in: 90e5c8226a user: dan tags: vtab-limit-fix)
12:01
Add test demonstrating the problem at [forum:/forumpost/c243b8f856|forum post c243b8f856]. No fix yet. (check-in: 1685495c0a user: dan tags: vtab-limit-fix)
11:32
Fix the TreeView display of a LIMIT clause on a compound query. Debugging code only - not part of production builds. (check-in: 38f1e5ce4e user: drh tags: trunk)
2024-04-25
23:26
Improvement to the way that affinity is determined for columns of a compound subquery. The affinity is the affinity of the left-most arm of the compound subquery that has an affinity other than NONE, adjusted to accommodate the data types coming out of the other arms. (check-in: e6df846f36 user: drh tags: trunk)
17:52
Further improvements to the computation of affinity for compound subqueries: make sure that the selected affinity is compatible with a literal values in arms to the left of the arm that is used to determine affinity. (Closed-Leaf check-in: bbdf22e3d9 user: drh tags: compound-subquery-affinity)
06:52
wasm: add a makefile comment about the static sqlite3.h/c version info injected into the JS files possibly differing from the runtime-emited version info when a user provides their own sqlite3.c. (check-in: d99a01a0f6 user: stephan tags: trunk)
2024-04-24
19:49
An experimental minor tweak to the way affinities are computed for compound subqueries, when the actual affinity is ambiguous. (check-in: 779723ad79 user: drh tags: compound-subquery-affinity)
16:36
If a RETURNING clause contains a subquery that references the table that is being updated in the statement that includes the RETURNING clause, then mark the subquery as correlated so that it is recomputed for each result and not just computed once and reused. See [forum:/forumpost/2c83569ce8945d39|forum post 2c83569ce8945d39]. (check-in: 9ea6bcc8fd user: drh tags: trunk)
14:18
Fix a case where a corrupt stat4 record could go unrecognized due to integer overflow. (check-in: 240a4a48b2 user: dan tags: trunk)
11:51
Add comments linking the assert() added in [cef4d9e3ba586735] to the places where the precondition that the assert() tests are actually required. (check-in: 6f0e7e1952 user: drh tags: trunk)
11:40
Avoid slowdown when exprNodeIsConstant() is called on deeply nested SQL functions. (check-in: 1c0b034545 user: dan tags: trunk)
11:21
Ensure that temporary SrcItem objects created by trigger processing have either SrcItem.zName or SrcItem.pSelect defined. Every SrcItem should have one or the other. (check-in: cef4d9e3ba user: drh tags: trunk)
06:43
Remove an undocumented feature from the JS Worker1.open API because it relies on broken behavior which has no VFS-agnostic workaround. (check-in: 3a640038c7 user: stephan tags: trunk)
2024-04-23
12:02
Fix a problem with vector IN operators used with an index where the affinities and collations for the various vector terms are different. (check-in: 86e8c782e7 user: drh tags: trunk)
11:56
Fix an uninitialized variable problem in the new code on this branch. (Closed-Leaf check-in: 85625b3871 user: dan tags: vector-in-fix)
06:49
Remove some dead WASM-side code. (check-in: 0a07ee27bd user: stephan tags: trunk)
06:36
Minor touchups in JS docs and exception messages. (check-in: 9e7fc9370d user: stephan tags: trunk)
05:38
When running the 'dist' target in ext/wasm for an SEE-capable build, ensure that the resulting zip file and directory name include '-see'. (check-in: 04c552b12e user: stephan tags: trunk)
2024-04-22
20:09
Add extra tests for aborting conflicts in the sessions module. (check-in: b4a6d32662 user: dan tags: trunk)
17:03
Minor cleanups to [8fbda563d2f5]. (check-in: 5ee2594b65 user: stephan tags: trunk)
16:46
Extend the JS/WASM SEE build support by (A) filtering SEE-related bits out of the JS when not building with SEE and (B) accepting an optional key/textkey/hexkey option to the sqlite3.oo1.DB and subclass constructors to create/open SEE-encrypted databases with. Demonstrate SEE in the test app using the kvvfs. This obviates the changes made in [5c505ee8a7]. (check-in: 8fbda563d2 user: stephan tags: trunk)
13:31
Extra robustness in the code that causes cursors to return NULL when they are participating in an OUTER JOIN. (check-in: 672c2869ef user: drh tags: trunk)
11:48
For sqlite3.oo1.DB JavaScript classes, bypass execution of any on-open() SQL in SEE-capable builds because it would necessarily run before the client has an opportunity to provide their decryption key, which would leave the db handle in an unusable state and cause the ctor to throw. This currently affects only the OPFS VFSes. We may want to consider extending the ctor options object to optionally accept an SEE key and apply it when opening the db. (check-in: 5c505ee8a7 user: stephan tags: trunk)
00:42
Continuation of the fix at [8c0f69e0e4ae0a44]: If a viaCoroutine FROM clause term is participating in a RIGHT or FULL JOIN, we have to create an always-NULL pseudo-cursor for that term when processing the RIGHT join. dbsqlfuzz 6fd1ff3a64bef4a6c092e8d757548e95698b0df5. (check-in: e1040e51eb user: drh tags: trunk)
2024-04-21
23:35
Fix an indentation problem in debugging routine sqlite3ShowSrcList(). No changes to production code. (check-in: 5560df2726 user: drh tags: trunk)
2024-04-20
15:14
Fix a problem where an expression like (a, b) IN (SELECT ...) might not use an index on (a, b) if the affinities and collation sequences of "a" and "b" are not identical. (check-in: 4d870fd8b5 user: dan tags: vector-in-fix)
2024-04-18
16:11
Correct handling of OUTER JOIN when on or the other operand is a subquery implemented using the VALUES-as-coroutine optimization. dbsqlfuzz bde3bf80aedf25afa56e2997a0545a314765d3f8. (check-in: 8c0f69e0e4 user: drh tags: trunk)
2024-04-15
20:43
The first assert() added in [0ebc65481f4a3e79] is not necessarily true in a corrupt database file. So add a term to make it true. (check-in: 6b21cccdee user: drh tags: trunk)
20:24
Add experimental way to specify an alternative tokenizer when writing to or querying an fts5 table. (check-in: 6c51c9c6a8 user: dan tags: fts5-tokenize-blob)
14:39
Merge the latest trunk enhancements into the wal2 branch. (Leaf check-in: 4a72acbc4b user: drh tags: wal2)
14:36
Merge the latest trunk enhancements into the begin-concurrent branch. (Leaf check-in: eedf6bed2a user: drh tags: begin-concurrent)
