2019-02-21
18:11
Fix OOM handling in sqlite3NestedParse(). Leaf check-in: e6e9dd5c17 user: dan tags: nested-parse-oom
16:41
Detect oversized strings in the OP_String opcode even if the P4 argument is originally UTF8 and has to be converted to UTF16 to match the database file and that conversion causes the string to become shorter and cross below SQLITE_LIMIT_LENGTH threshold. This might fix an OSSFuzz problem that we have been so far unable to reproduce. check-in: c13d563925 user: drh tags: trunk
2019-02-20
19:20
Changes to the unix VFS that allegedly enable it to build of Fuchsia. We have no way of testing this. check-in: be21a6416d user: drh tags: trunk
19:06
Disable unix-specific features of dbfuzz2 when compiling on windows. check-in: af84774d1e user: drh tags: trunk
18:13
Avoid the use of function pointers in columnName(), as function pointers appear to be a source of consternation to LLVM. check-in: c48f6f39c5 user: drh tags: trunk
13:55
Progress handler improvements: (1) Invoke the callback after OP_Program opcodes (2) Invoke the callback multiple times in a row to catch up after a long run of no progress checks. check-in: 0c5db18d79 user: drh tags: trunk
12:52
When an IN operator drives a query loop, mark it as "CODED" so that it will not be used afterwards for a (pointless) membership test. This is a better fix for ticket [df46dfb631f75694] than the previous fix that is now on a branch as it preserves the full optimization of check-in [e130319317e76119]. check-in: fa792714ae user: drh tags: trunk
2019-02-19
20:29
Enhance the xBestIndex method on delta_parse() to return SQLITE_CONSTRAINT if no delta argument is supplied. check-in: f16d127c3b user: drh tags: trunk
20:19
Add the delta_parse(DELTA) table-valued function to the fossildelta extension. check-in: d91fcc267b user: drh tags: trunk
18:39
Add the fossildelta.c extension in ext/misc with implementations of the Fossil delta functions. check-in: b80cafa6f8 user: drh tags: trunk
17:45
Fix a potential memory leak in RBU if the rbu_fossil_delta() SQL function is misused. Misuse never happens in a working RBU system, so this is not a particularly important fix. check-in: 12517d1b15 user: drh tags: trunk
16:42
Fix an assert() that might not be true if the database file is corrupt. check-in: f2d400db4d user: drh tags: trunk
13:51
New assert() to verify the TF_HasprimaryKey flag. check-in: 0abace8a7a user: drh tags: trunk
13:08
Always use the symbolic name SQLITE_IDXTYPE_PRIMARYKEY rather than a hard-coded magic number 2. check-in: 55d43adc89 user: drh tags: trunk
2019-02-18
12:16
Fix an assert() that might not be true if the %_segdir table of FTS3 contains corrupt entries. check-in: a6509ca3dc user: drh tags: trunk
2019-02-16
22:45
Fix an assert() that might be false for a corrupt database. check-in: 0cfb888723 user: drh tags: trunk
2019-02-14
15:27
Improved oversized cell detection when updating ptrmap pages in balance_nonroot(). check-in: aa61435a4c user: drh tags: trunk
2019-02-12
22:58
Ensure that the nProgressLimit variable is always initialized in sqlite3VdbeExec(), even if the routine jumps to its exit processing early. check-in: 167b91df77 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: 68cce272e7 user: drh tags: trunk
16:58
Further performance improvements to btreeInitPage(). check-in: 93ae382e97 user: drh tags: trunk
15:51
Increase the version number to 3.28.0 for the next release cycle. check-in: 6eb38c59a8 user: drh tags: trunk
12:25
Register the "vfsstat" virtual table immediately when loading the vfsstat.c extension. check-in: 9bd92afd0c user: drh tags: trunk
01:28
New test cases in test/fuzzdata8.db. check-in: ab2356f580 user: drh tags: trunk
01:04
Defer computing the number of bytes of free space on a btree page until that value is actually needed. check-in: 177f5f40ea user: drh tags: trunk
00:58
Change an assert() into a NEVER(), since the condition is difficult to prove with certainty. Improved comment on the MemPage.nFree field. Closed-Leaf check-in: fec071b89d user: drh tags: deferred-free-space
2019-02-11
22:50
Do not invoke btreeComputeFreeSpace() when not necessary. check-in: f11b0ed474 user: drh tags: deferred-free-space
19:27
Improvements to comments. No changes to code. check-in: 16eb0fc8f8 user: drh tags: deferred-free-space
17:22
Fix test cases. Avoid unnecessary tests for MemPage.nFree less than zero. check-in: 480a5090be user: drh tags: deferred-free-space
16:12
Fix another segfault that could occur in fts5 with a corrupted database. check-in: 09e337386b user: dan tags: trunk
13:25
Fix typos in comments in fts5.h. No changes to code. check-in: c19e97bc92 user: dan tags: trunk
12:51
Updates to a comment to keep it in alignment to the changes on this branch. check-in: 7499f74351 user: drh tags: deferred-free-space
11:34
Build and test fixes for SQLITE_OMIT_WINDOWFUNC builds. check-in: 8824115a97 user: dan tags: trunk
11:04
Avoid using a "return void_function();" statement in void function sqlite3WalSnapshotUnlock(). It provokes a warning from some compilers. check-in: 4a4952d38e user: dan tags: trunk
01:58
Add an assert() in an attempt to repro an ASAN warning from OSSFuzz. check-in: 7b41222428 user: drh tags: trunk
2019-02-09
22:33
Fix a page-cache reference leak in the btree balancer when there is a corrupt database. check-in: 9285899120 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: 1d43ee4000 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: db74a56af7 user: dan tags: trunk
2019-02-08
22:34
Small performance improvement and size reduction for pageFindSlot() - the routine in btree.c that locates a free slot for a cell on a btree page. check-in: 1969372ac7 user: drh tags: trunk
17:28
Further simplifications to sqlite3VdbeMemSetStr(). check-in: 1d21295707 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: 5c499da8a4 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: 5c6638040b 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: 440a7cda00 user: drh tags: trunk
2019-02-07
19:07
Change VACUUM so that it preserves ROWID values. check-in: 49e5d11d46 user: drh tags: trunk
17:02
Version 3.27.0 check-in: 97744701c3 user: drh tags: trunk, release, version-3.27.0
15:09
Experimental change to VACUUM so that it preserves existing ROWID values. Closed-Leaf check-in: f264015f84 user: drh tags: vacuum-preserves-rowid
00:17
In the fuzzcheck test program, make sure the isspace() and related routines are not given values outside the range of -1 to 255. check-in: f298328771 user: drh tags: trunk
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: a505e34d4e user: dan tags: trunk
20:12
Update an assert() in test_journal.c to take the new "VACUUM INTO" functionality into account. check-in: 0e6249cb95 user: dan tags: trunk
19:42
Avoid attempting to delete a file while it is still open in walfault2.test. check-in: 9d54a63d6e user: dan tags: trunk
18:08
Update test file dbfuzz001.test so that it works with SQLITE_ENABLE_OVERSIZE_CELL_CHECK builds. check-in: 4371a0c46e user: dan tags: trunk
15:23
Add -DSQLITE_ENABLE_DESERIALIZE to the default testing configuration in test/releasetest.tcl. check-in: 433d6ef637 user: dan tags: trunk
