2019-02-26
| ||

|
2019-02-23
| ||
| 20:48 | Fix a couple of assert() statements in fts3 that can be false if the database is corrupt. check-in: 84162af5 user: dan tags: trunk | |
| 00:21 | Check-in [fa792714ae62fa98] is incorrect. Add a test case to refute it and also a fix to make it right. Then add an alternative fix to ticket [df46dfb631f75694] in which all ephemeral tables used as the RHS of an IN operator be index btrees and never table btrees so that they can always be reused. check-in: d3915230 user: drh tags: trunk | |
|
2019-02-22
| ||
| 19:24 | Internally, remove all references to a Window object that belongs to an expression in an ORDER BY clause if that expression is converted to an alias of a result-set expression. Fix for [4feb3159c6]. check-in: 579b66ea user: dan tags: trunk | |
| 16:18 | In sqlite3NestedParse() be sure to detect all SQLITE_NOMEM and SQLITE_TOOBIG errors and to distinguish between them. check-in: 73056b31 user: drh tags: trunk | |
| 15:42 | Modify sqlite3_str_finish() and sqlite3VMPrintf() so that they always return NULL on any OOM or SQLITE_LIMIT_LENGTH error. check-in: e7144ffd user: drh tags: trunk | |
|
2019-02-21
| ||
| 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: c13d5639 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: be21a641 user: drh tags: trunk | |
| 19:06 | Disable unix-specific features of dbfuzz2 when compiling on windows. check-in: af84774d 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: c48f6f39 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: 0c5db18d 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: fa792714 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: f16d127c user: drh tags: trunk | |
| 20:19 | Add the delta_parse(DELTA) table-valued function to the fossildelta extension. check-in: d91fcc26 user: drh tags: trunk | |
| 18:39 | Add the fossildelta.c extension in ext/misc with implementations of the Fossil delta functions. check-in: b80cafa6 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: 12517d1b user: drh tags: trunk | |
| 16:42 | Fix an assert() that might not be true if the database file is corrupt. check-in: f2d400db user: drh tags: trunk | |
| 13:51 | New assert() to verify the TF_HasprimaryKey flag. check-in: 0abace8a user: drh tags: trunk | |
| 13:08 | Always use the symbolic name SQLITE_IDXTYPE_PRIMARYKEY rather than a hard-coded magic number 2. check-in: 55d43adc 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: a6509ca3 user: drh tags: trunk | |
|
2019-02-16
| ||
| 22:45 | Fix an assert() that might be false for a corrupt database. check-in: 0cfb8887 user: drh tags: trunk | |
|
2019-02-14
| ||
| 15:27 | Improved oversized cell detection when updating ptrmap pages in balance_nonroot(). check-in: aa61435a 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: 167b91df 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 | |
| 15:51 | Increase the version number to 3.28.0 for the next release cycle. check-in: 6eb38c59 user: drh tags: trunk | |
| 12:25 | Register the "vfsstat" virtual table immediately when loading the vfsstat.c extension. check-in: 9bd92afd user: drh tags: trunk | |
| 01:28 | New test cases in test/fuzzdata8.db. check-in: ab2356f5 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: 177f5f40 user: drh tags: trunk | |
|
2019-02-11
| ||
| 16:12 | Fix another segfault that could occur in fts5 with a corrupted database. check-in: 09e33738 user: dan tags: trunk | |
| 13:25 | Fix typos in comments in fts5.h. No changes to code. check-in: c19e97bc user: dan tags: trunk | |
| 11:34 | Build and test fixes for SQLITE_OMIT_WINDOWFUNC builds. check-in: 8824115a 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: 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 | |
|
2019-02-09
| ||
| 19:23 | Change a few assert() statements in fts3 that might fail if the database is corrupt. check-in: db74a56a 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: 1969372a user: drh 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 | Change VACUUM so that it preserves ROWID values. check-in: 49e5d11d user: drh tags: trunk | |
| 17:02 | Version 3.27.0 check-in: 97744701 user: drh tags: trunk, release, version-3.27.0 | |
| 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: f2983287 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: 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 | |
| 19:42 | Avoid attempting to delete a file while it is still open in walfault2.test. check-in: 9d54a63d user: dan tags: trunk | |
| 18:08 | Update test file dbfuzz001.test so that it works with SQLITE_ENABLE_OVERSIZE_CELL_CHECK builds. check-in: 4371a0c4 user: dan tags: trunk | |
| 15:23 | Add -DSQLITE_ENABLE_DESERIALIZE to the default testing configuration in test/releasetest.tcl. check-in: 433d6ef6 user: dan tags: trunk | |
| 13:48 | Do not attempt to test the shell ".trace" command in SQLITE_OMIT_TRACE builds. check-in: 3839e909 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 | |
