16:52
In the test_vfs.c VFS, if a Tcl xWrite script returns "SQLITE_OMIT", silently omit the write() call. (check-in: 8b5a621e user: dan tags: trunk)
16:38
Add the ability to override the new corruption detection logic of the previous checkin, in order to exercise downstream corruption detection during testing. (check-in: e859d318 user: drh tags: trunk)
15:44
In the xfer-optimization, do early detection of when the source and destination index share the same btree, to avoid a long delay prior to reporting the database corruption. (check-in: af1e5873 user: drh tags: trunk)

18:20
Minor fixes to requirements marks. (check-in: 02ebc60b user: drh tags: trunk)
17:58
Add test cases to improve coverage of VDBE branches. Still some to go. (check-in: 4cef609d user: dan tags: trunk)

Correctly initialize the loadable extension thunk. (check-in: 4fca46de user: drh tags: trunk)
15:25
Simplification of the recent VACUUM changes that make the code more like what it was before the change. Also, make the VACUUM command a no-inline procedure to work around a performance regression. (check-in: 9cac5ac1 user: drh tags: trunk)
14:36
Fix an incorrect comment on a test case for rowid renumbering in VACUUM. (check-in: 0d293fb4 user: drh tags: trunk)

Use a separate bit on db->dbOptFlags to disable the xInverse optimization on window functions, rather than reusing the query-flattener disable bit. (check-in: bc0fb1c3 user: drh tags: trunk)
17:45
Including the phrase EXCLUDE NO OTHERS in the frame-spec of a window function (which is the default setting for EXCLUDE) silently disables the xInverse optimization.

16:23
Frame range comparisons can never be NULL because the values will have been checked for NULL prior to the test. (check-in: fa37cf9a user: drh tags: trunk)

The defragmentPage() routine detects corruption in the first-free-slot fields at offset 1 in the header and throws an error, rather than asserting. (check-in: fb125bd3 user: drh tags: trunk)
17:30
Add the blobio.c extension module implementing readblob() and writeblob(). Experimental. (check-in: e3fde56d user: drh tags: trunk)

11:48
Fix typos in the comments of the sessions extension, one of which affects the generated documentation. No code changes. (check-in: 040d5d51 user: drh tags: trunk)

The two-argument version of fts3_tokenizer() works regardless of the value of SQLITE_DBCONFIG_ENABLE_FT3_TOKENIZER as long as the second argument is a bind parameter. (check-in: ab76e3a9 user: drh tags: value_frombind)

Initial implementation of the sqlite3_value_frombind() interface. (check-in: 98da62df user: drh tags: value_frombind)

13:53
Show the pointer address for Window objects in the TreeView display. (check-in: 1ae70ad2 user: drh tags: trunk)
13:35
More improvements to TreeView output for Window objects: (1) Show when the frame-spec is implied rather than explicit. (2) Move the FILTER clause out from within the OVER clause, making it a sibling of the OVER clause, to match syntax. (check-in: d6a07433 user: drh tags: trunk)
13:03
Improved TreeView display of Window objects. Change the Window.eType field to Window.eFrmType to avoid confusion with other "eType" values. (check-in: ec2f207d user: drh tags: trunk)
04:03
If the string formatter in sqlite3NestedParse() fails due to an over-length string, make sure this error is recorded by the parser so that it knows to fail. (check-in: 85e53ff1 user: drh tags: trunk)

21:04
Enhancement the progress callback mechanism so that the progress callback is always invoked at least once at the end of a prepared statement if the opcode count has been exceeded. This makes the progress callback more effective at limiting run times. This check-in also includes and unrelated performance enhancement to OP_Column. (check-in: 68cce272 user: drh tags: trunk)
16:58
Further performance improvements to btreeInitPage(). (check-in: 93ae382e user: drh tags: trunk)

2019-02-11
22:50
Do not invoke btreeComputeFreeSpace() when not necessary. (check-in: f11b0ed4 user: drh tags: deferred-free-space)

11:04
Avoid using a "return void_function();" statement in void function sqlite3WalSnapshotUnlock(). It provokes a warning from some compilers. (check-in: 4a4952d3 user: dan tags: trunk)
01:58
Add an assert() in an attempt to repro an ASAN warning from OSSFuzz. (check-in: 7b412224 user: drh tags: trunk)

Fix a page-cache reference leak in the btree balancer when there is a corrupt database. (check-in: 92858991 user: drh tags: deferred-free-space)
21:06
Defer computing the MemPage.nFree value of an in-memory btree page until it is actually needed, since for many pages it is never needed. This checkin works sufficiently to prove the concept, but still has issues with exception handling. (check-in: 1d43ee40 user: drh tags: deferred-free-space)
19:23
Change a few assert() statements in fts3 that might fail if the database is corrupt. (check-in: db74a56a user: dan tags: trunk)

17:28
Further simplifications to sqlite3VdbeMemSetStr(). (check-in: 1d212957 user: drh tags: trunk)
15:59
Change the sqlite3VdbeMemGrow() routine so that it no longer guarantees a minimum size of 32 bytes. That minimum is no longer required, and without the extra check for the minimum size, the routine runs faster. (check-in: 5c499da8 user: drh tags: trunk)
14:55
Give the sqlite3 object a pointer to the current Parse so that if an OOM occurs, it can automatically set the Parse.rc value to SQLITE_NOMEM. This avoids a frequent extra test of db.mallocFailed in the innermost parser loop. (check-in: 5c663804 user: drh tags: trunk)
04:15
Do not do the optimization that attempts to pull expression values from an index on that expression when processing a multi-index OR (see check-in [a47efb7c8520a0111]) because the expression transformations that are applied become invalid when the processing moves off of the current index and on to the next index. Fix for ticket [4e8e4857d32d401f]. (check-in: 440a7cda user: drh tags: trunk)
2019-02-07
19:07

2019-02-06
20:49
Ensure all bytes of the PgHdr1 structure are initialized. This avoids a valgrind error when running corruptI.test. (check-in: a505e34d user: dan tags: trunk)
20:12
Update an assert() in test_journal.c to take the new "VACUUM INTO" functionality into account. (check-in: 0e6249cb user: dan tags: trunk)

13:41
Fix a problem preventing testfixture from being built with SQLITE_OMIT_VIRTUALTABLE. (check-in: d2cca36a user: dan tags: trunk)
01:18
When extending the size of SrcList objects, do not attempt to use extra space on the end of the allocation, as that provides scarcely any performance benefit but does greatly complicate cross-platform testing. (check-in: 3087a0c3 user: drh tags: trunk)
00:55
If the query flattener detects an error, cause the SELECT code generator to abort immediately. (check-in: 3d3b142f user: drh tags: trunk)
00:11

21:08
Slight adjustment to the printf formatter large memory allocation detector so that it does not overestimate the amount of space needed for oversize %d conversions. (check-in: 1aee70d6 user: drh tags: trunk)
20:29
Prevent the printf formatter from doing large memory allocations - larger than either the size of the static buffer for interfaces like sqlite3_snprintf(), or larger than SQLITE_LIMIT_LENGTH for interfaces that are associated with a database connection. This helps to prevent DOS attacks on products that let hostile sources inject arbitrary SQL. It also helps fuzzers run faster and more effectively. (check-in: 179e5d46 user: drh tags: trunk)

02:42
If the amalgamation file "sqlite3.c" is generated using the SQLITE_ENABLE_UPDATE_DELETE_LIMIT option, but then subsequently (mis-)compiled without that option, and then a particular syntax error could cause a memory leak, but for this fix. (check-in: 1bb17c86 user: drh tags: trunk)
01:39

16:58
Fix an off-by-one error when parsing the names of indexes that do not have arguments in the index_usage utility. (check-in: dc794d8f user: drh tags: trunk)
