00:14 | Remove the BtreeMutexArray object - use the Vdbe.btreeMask field to accomplish the same result. Add a generation counter to btree mutexes in order to assert that mutexes are never temporarily dropped over a range of instructions in order to do deadlock avoidance in some subroutine. Lock all btrees in any Vdbe program that uses OP_ParseSchema. (check-in: d81708f7 user: drh tags: trunk) | |

18:19 | Make sure that the constant 1 is cast to yDbType before shifting to create an attached database mask. This check-in is a follow-up and fix to the [7aaf8772274422] change that increases the maximum number of attached databases from 30 to 62. (check-in: e2a09ea7 user: drh tags: trunk) | |

17:53 | Change analyze7.test so that it works without SQLITE_ENABLE_STAT2 defined. (check-in: 9415201c user: dan tags: trunk) | |
16:50 | When simulating an error in the close() system call, close the file descriptor anyway. Otherwise long running tests leak too many file-descriptors and crash. (check-in: 81ddbf43 user: dan tags: trunk) | |

2011-03-30
| ||
21:03 | Updates to multiplex.test script; misc. bug fixes; (check-in: c41ff235 user: shaneh tags: multiplex-enhancements) | |

18:28 | Add tests to syscall.test and sysfault.test. (check-in: 3d2de011 user: dan tags: trunk) | |
18:21 | The first simple test-case appears to be working now. (check-in: dd41155b user: drh tags: word-fuzzer) | |
15:40 | Fix a problem whereby following an IO error in CommitPhaseTwo() of a multi-file transaction the b-tree layer could be left in TRANS_WRITE state, causing problems later on. (check-in: dbe569a0 user: dan tags: trunk) | |
14:08 | Further improvements to the fuzzer. It still is not quite working. Pausing to work on other things.... (check-in: 5f2f2fce user: drh tags: word-fuzzer) | |
10:04 | Fix a problem in the unix VFS implementation of xNextSystemCall(). Also some typos that prevent compilation when HAVE_POSIX_FALLOCATE is defined. (check-in: bc6cce81 user: dan tags: trunk) | |
05:06 | In-progress changes - do not use; Removed prefix support; Added file control interface to enable/disable and adjust chunk size; added app-def function for same; (check-in: bc02d0c1 user: shaneh tags: multiplex-enhancements) | |

2011-03-28
| ||

15:05 | Skeleton code for the word-fuzzer virtual table. (check-in: ea3a4ee1 user: drh tags: word-fuzzer) | |
2011-03-24
| ||
17:43 | Minor change to sqlite3Utf8Read() to make consistent with READ_UTF8() usage and avoid implementation defined usages of <<. Added some additional UTF-8 test cases. (check-in: 7173b392 user: shaneh tags: trunk) | |
17:37 | Fix problem with tableapi.test on Windows. (check-in: 69fe0c87 user: shaneh tags: trunk) | |
01:34 | The changes to fix [f7b4edece25c9948] mean that the schema is always loaded whenever a prepared statement is running. This means that a couple of branches can be eliminated and one operand of OP_ParseSchema can be removed. (check-in: b6e268fc user: drh tags: trunk) | |
2011-03-23
| ||
22:54 | Fix a signed/unsigned comparison compiler warning. (check-in: c81da6f9 user: drh tags: trunk) | |

2011-03-17
| ||
16:45 | Update the implementation of ".testctrl" in the command-line shell to use a look-up table rather than a long sequence of if-elses. Shorten source code lines of shell.c to 80 characters or less. (check-in: 54bacb95 user: drh tags: trunk) | |
01:58 | Comment enhancement to better explain the logic in the "x IS NULL" optimization. (check-in: 869f8947 user: drh tags: trunk) | |
01:34 | Enhances to the query planner such that "x IS NULL" constraints take the STAT2 statistics into account, just like "x=VALUE" constraints. (check-in: 23531768 user: drh tags: trunk) | |
2011-03-16
| ||
18:54 | Additional interpretation of flags and constants in the VFS trace output. (check-in: 3e984195 user: drh tags: trunk) | |

2011-03-12
| ||
18:10 | In the "unix-excl" VFS, use the heap for shared memory, since only a single process is able to read or write the database. (Closed-Leaf check-in: a05a6d40 user: drh tags: unix-excl) | |
17:02 | Add the new optional "unix-excl" VFS. This VFS grabs an exclusive lock on the database preventing other processes from accessing it, but continues to allow other database connections from the same process. (check-in: 00051c32 user: drh tags: unix-excl) | |
04:58 | More tests for SQLITE_OMIT_UNIQUE_ENFORCEMENT and minor change to implementation. (check-in: b8699943 user: shaneh tags: trunk) | |

21:13 | Skip unique constraint enforcement if compiled with SQLITE_OMIT_UNIQUE_ENFORCEMENT. (check-in: ba85bf8c user: shaneh tags: trunk) | |
03:54 | Minor clean-up of previous mem5 allocator fix. (check-in: 36438423 user: shaneh tags: trunk) | |
2011-03-09
| ||
21:36 | Fix issue with mem5 allocator when min request size is larger thatn 2^30. (check-in: d7dae06f user: shaneh tags: trunk) | |
21:02 | Omit unnecessary OP_Next and OP_Prev operators when uniqueness constraints guarantee that the code will only make one pass through the loop. (check-in: f000c9b2 user: drh tags: trunk) | |
11:04 | Updates to the OS/2 implementation from Rich Walsh. (check-in: dc46156a user: drh tags: trunk) | |
2011-03-08
| ||
16:39 | Merge the syscall-override changes into trunk. (check-in: 36d79e6f user: drh tags: trunk) | |
14:05 | Unix errno integer can vary from one system to the next. So do not depend on specific errno values in test cases. (check-in: ddb747d3 user: drh tags: trunk) | |
13:06 | Fix two compiler warnings. No functional code changes. (check-in: c829868a user: drh tags: trunk) | |

2011-03-05
| ||
21:41 | Simplifications to the overflow-free multiplier. Also remove some commented-out code that was left in that subroutine by mistake on the previous check-in. (check-in: 55fc25fd user: drh tags: trunk) | |
20:59 | Fix all known instances of signed-integer overflow. Within SQL expressions, integer overflow now forces coercion to floating point. The shift operators work with any integer right-hand operand with negative values reversing the direction of the shift. (check-in: abf21394 user: drh tags: trunk) | |
13:54 | Fix an instance of signed arithmetic overflow and an one bit-shift overflow. Mark six other signed arithmetic overflow locations that need fixing. (check-in: 04abab71 user: drh tags: trunk) | |
2011-03-04
| ||
15:43 | Handle EINTR errors from open(). (Closed-Leaf check-in: a7d176b2 user: drh tags: syscall-override) | |
00:56 | Do a better job of choosing the join table order when the tables having very different numbers of rows. (check-in: 952f5e8c user: drh tags: trunk) | |

22:07 | Fix quoting of the result in rtreeB.test. (check-in: c6532b35 user: drh tags: trunk) | |
19:06 | Add additional VFS methods to retrieve system call pointers and to get a list of all changeable system calls. (check-in: 38558363 user: drh tags: syscall-override) | |
18:01 | Add more system calls to the set that can be overridden in os_unix.c. Also merge in recent fixes from trunk. (check-in: 80fac2a6 user: drh tags: syscall-override) | |
17:54 | Fix bugs in [7b6e30e6a7] that only show up on Mac. (check-in: ec55e8c6 user: drh tags: trunk) | |
15:44 | Make sure the rtreenode() testing and analysis routine in the RTREE extension can handle 64-bit rowids. This fix is in response to a message on the mailing list. (check-in: 24602557 user: drh tags: trunk) | |
15:09 | Proof-of-concept prototype for the proposed xSetSystemCall extension method on the VFS. (check-in: 92b5a76a user: drh tags: syscall-override) | |
02:08 | Log all error from close() in os_unix.c to sqlite3_log() but do not attempt to report errors back up to the application. Update the unix error logging to put the most important information earlier in the message. (check-in: 7b6e30e6 user: drh tags: trunk) | |
2011-02-25
| ||
03:25 | Comment out some code in os_unix.c that only runs on MacOSX with SQLITE_ENABLE_LOCKING_STYLE. (check-in: 4e50b036 user: drh tags: trunk) | |

| ||
21:10 | Fix a typo in a comment. No changes to code. (check-in: af475618 user: drh tags: trunk) | |
2011-02-23
| ||
22:39 | Reserve a range of bits in the SQLITE_OPEN_xxxx bit vector for future expansion. (check-in: 9b904654 user: drh tags: trunk) | |
