| 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
| ||
| 22:33 | 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 | |

| ||
| 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 | |
| 20:55 | Use a fast compiler-provided memory barrier exclusively, if such a memory barrier is available. Leaf check-in: df66fec9 user: drh tags: faster-memory-barrier | |
| 19:30 | Add test cases and fix problems on this branch. check-in: 2b2e9f81 user: dan tags: reuse-schema | |
| 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 | |
| 14:59 | Merge the fix for ticket [4e8e4857d32d401f], so that this branch now contains release 3.27.1 plus the extra patch to preserve ROWID values on VACUUM. check-in: 0cdae60e user: drh tags: apple-osx | |
| 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 | |
| 13:17 | Version 3.27.1 check-in: 0eca3dd3 user: drh tags: release, branch-3.27, version-3.27.1 | |
| 12:46 | Cherrypick the fix for ticket [4e8e4857d32d401f] from trunk. check-in: d5d944d7 user: drh tags: branch-3.27 | |
| 12:44 | Increase the version number to 3.27.1. check-in: b94d5428 user: drh tags: branch-3.27 | |
| 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 | |

| 19:28 | Pull in the change that causes VACUUM to preserve rowid values. check-in: c9af2f71 user: drh tags: apple-osx | |
| 19:07 | Change VACUUM so that it preserves ROWID values. check-in: 49e5d11d user: drh tags: trunk | |
| 18:49 | Merge the offical 3.27.0 release. check-in: 62829164 user: drh tags: apple-osx | |
| 17:02 | Version 3.27.0 check-in: 97744701 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: f264015f 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: f2983287 user: drh tags: trunk | |

| 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 | |
| 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 | Back out check-in [008112bcef561a8], reenabling deprecated PRAGMAs when the SQLITE_OMIT_DEPRECATED compile-time option is used, because way too many TH3 tests depend on those deprecated PRAGMAs. check-in: 9dbf512d user: drh tags: trunk | |

| 19:15 | Fix memory leaks on this branch. check-in: e9c5e189 user: dan tags: reuse-schema | |
| 16:53 | Update the tester.tcl --malloctrace option so that it uses eu-addr2line instead of addr2line. check-in: 79c07387 user: dan tags: trunk | |
| 14:36 | The IS NOT NULL operator does not imply that the operand is never NULL. Fix for ticket [5948e09b8c415bc45da5cf] check-in: d840e9bb user: drh tags: trunk | |
| 12:16 | Keep the temp_store_directory and data_store_directory pragmas even when compiling with SQLITE_OMIT_DEPRECATED. check-in: 93386a7c user: drh tags: trunk | |
| 08:55 | Update test file "resetdb.test" so that it works with the "prepare" permutation. check-in: 95d33812 user: dan tags: trunk | |

| 21:02 | Fix a problem with reloading the schema on this branch. check-in: 5dfbef83 user: dan tags: reuse-schema | |
| 19:52 | Mention the new -memtrace command-line option in the -help output of the CLI. check-in: ada91aef user: drh tags: trunk | |
| 19:50 | Add the -memtrace option to dbfuzz2. check-in: 67fecbc7 user: drh tags: trunk | |
| 19:45 | Enhance dbfuzz2 so that with the -v option it shows the return code and error message for any failing SQL statements. check-in: 3a127ef9 user: drh tags: trunk | |
| 19:12 | Ensure that the sqlite3_exec() callback gets the correct number of columns for a query, even if the schema changes out from under it. check-in: a16ffb5a user: drh tags: trunk | |
| 16:42 | Do not run shmlock.test as part of the inmemory_journal permutation. check-in: d3fea69c user: dan tags: trunk | |

| 07:46 | Fix an assertion failure in fts3 triggered by a corrupt database. check-in: 560ebd42 user: dan tags: trunk | |
|
2019-02-02
| ||
| 21:02 | Try new approach ensuring that each Schema object is only used by one connection/database at any one time. check-in: 9e8e5f52 user: dan tags: reuse-schema | |
| 18:24 | New testcase added to test/fuzzdata8.db. check-in: 2f5c1925 user: drh tags: trunk | |
| 15:59 | Honor key query parameters for SEE on the URI filename for ATTACH and VACUUM INTO. check-in: 2e01096b user: drh tags: trunk | |

| 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 | |
| 18:46 | Performance improvement in the parsing of options to %-formats in the printf implementation. check-in: 40d8f8ae user: drh tags: trunk | |
| 15:06 | Ensure that the Walker.pParse structure is initialized when walking the source tree to gather the WINDOW clauses on a query with window functions. check-in: 4ca9d5d5 user: drh tags: trunk | |

| 14:40 | Fix an assert() in fts5 that could fail if the database is corrupt. check-in: 55f06aa3 user: dan tags: trunk | |
| 13:34 | Fix another corrupt-database-handling problem in fts5. check-in: 9876ae1b user: dan tags: trunk | |

| 16:09 | Remove an incorrect assert() from the deserialize in-memory database VFS. check-in: 80151d7e user: drh tags: trunk | |
| 15:38 | Add the SQLITE_CONFIG_MEMDB_MAXSIZE configuration option for configuring the default maximum size of an in-memory database created using sqlite3_deserialize(). This is necessary to make the interface reasonably testable. check-in: cb72ee04 user: drh tags: trunk | |
| 14:37 | Fix another buffer overrun that could occur when quering a corrupt database using an fts5vocab table. check-in: b80119bd user: dan 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 | Improvements to "PRAGMA parser_trace=ON": Make it a flag pragma, and then use the flag to show the complete SQL text at the beginning of the parse. check-in: 507c4353 user: drh tags: trunk | |

| 19:12 | When parsing the schema, check for duplicate index root page numbers before adding the index to the schema hash table. check-in: 6b360bc0 user: dan tags: trunk | |
| 18:47 | Add test case for the previous commit. check-in: 197edb23 user: dan tags: trunk | |
| 18:33 | Detect if two indexes of the same table share a common rootpage while parsing the schema, and throw an error immediately. check-in: f21c6f13 user: drh tags: trunk | |
| 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 | |
| 15:47 | Add the --progress, --using, and -q options to the index_usage utility program. check-in: a5e6be7c user: drh tags: trunk | |
| 14:01 | Enhancements to the index_usage utility program. check-in: 19c739b4 user: drh tags: trunk | |

| 16:47 | Load all the latest dbsqlfuzz finds into test/fuzzdata8.db. check-in: e744d2dd user: drh tags: trunk | |
| 16:41 | More robust handling of corrupt database file in the rebalance operation of the btree logic. check-in: 97704cb7 user: drh tags: trunk | |
| 16:34 | Avoid an integer overflow in the fts5 snippet() function triggered by a corrupt database record. check-in: 7c862c46 user: dan tags: trunk | |
| 15:30 | Avoid a crash when the fts5 snippet() function (or similar) is used with a special query pattern, like '*id' or '*reads'. check-in: 9d58a157 user: dan tags: trunk | |
| 11:42 | Fix a buffer overrun triggered by a merge operation on a corrupt fts5 database. check-in: 7ee3cd5b user: dan tags: trunk | |
| 02:37 | Set a low limit on the length of strings and blobs in the OSSFuzz module, in an effort to avoid timeouts when the fuzzer does things like "randomblob(1e12)". check-in: 119d1609 user: drh tags: trunk | |
