| 16:46 | Do not cast an unsigned int into an int for comparison. (CVS 6720) (check-in: 302ab855e6 user: drh tags: trunk) | |
| 14:17 | Take care that a corrupt variable-length integer does not cause 32-bit integer overflow when parsing a record format, nor cause excessively large memory allocations. (CVS 6719) (check-in: 38b20327a8 user: drh tags: trunk) | |

| 19:06 | Earlier detection of freelist corruption in the page allocation routines. (CVS 6718) (check-in: e557c8e584 user: drh tags: trunk) | |
| 17:02 | Fix an assertion fault in balance_quick() that occurs when an interior btree node has zero cells due to database corruption. Also update the corrupt7.test result vectors for a couple of cases where the error report on database corruption changed due to earlier detection. (CVS 6717) (check-in: 1335e4440f user: drh tags: trunk) | |
| 16:14 | If the root page of a btree is empty and is also not a leaf page and the page is not page 1, then report database corruption. (CVS 6716) (check-in: 52b02ca5f3 user: drh tags: trunk) | |
| 14:46 | Reduce the stack usage of balance_quick(). (CVS 6715) (check-in: e7ad68e93b user: danielk1977 tags: trunk) | |
| 02:47 | Minor updates to comments in test scripts. (CVS 6714) (check-in: 453ff88f73 user: shane tags: trunk) | |
| 02:46 | Minor tweak to test script to ensure every byte in file touched at least once. (CVS 6713) (check-in: bc6c2d894b user: shane tags: trunk) | |
| 00:11 | Fix two instances where a malformed header in a database file (in other words a corrupt database file) can lead to an assertion fault. (CVS 6712) (check-in: 4e92c7f20a user: drh tags: trunk) | |
|

| 21:04 | Change the pcache1.c implementation so that the "header" occurs at the end of page buffer, not at the beginning. This insures that the 20 bytes immediately following the page buffer are mapped if a read of the page buffer overruns due to a malformed cell. (CVS 6711) (check-in: c54de1f540 user: drh tags: trunk) | |
| 17:26 | Add corruptD.test, a container for testing the "cell overflow" problem. Also shuffle a small amount of code in BtreeInitPage() to check that the page header pointer to the start of the cell offset array is set to a sane value. (CVS 6710) (check-in: 7fa5d3cb0f user: danielk1977 tags: trunk) | |
| 11:25 | Define a set of constants to use as the "index" argument to sqlite3BtreeGetMeta and UpdateMeta. This makes some parts of the code easier to follow. (CVS 6709) (check-in: 6dbf4eca00 user: danielk1977 tags: trunk) | |
| 01:24 | Additional changes to reduce stack usage. The SQLITE_SMALL_STACK compile-time option is now available. (CVS 6708) (check-in: baea79fd0c user: drh tags: trunk) | |

| 21:31 | Further reductions in the amount of stack space required. (CVS 6707) (check-in: 04bad9eb6d user: drh tags: trunk) | |

| 15:47 | Add a test case for ticket #3893 and ticket #3894. (CVS 6705) (check-in: 2472f6db95 user: drh tags: trunk) | |
| 15:21 | Add the vdbe-compress.tcl script which automatically refactors the sqlite3VdbeExec() routine to use less stack space. Use this script when constructing the amalgamation. (CVS 6704) (check-in: 7f43391831 user: drh tags: trunk) | |
|
2009-06-01
| ||
| 19:53 | Avoid allocating large objects on the stack in the incremental BLOB I/O interface. (CVS 6703) (check-in: ea7dfde700 user: drh tags: trunk) | |
| 18:18 | Malloc for space to hold the Parse object in sqlite3_prepare() and friends. Or, if compiled with SQLITE_USE_ALLOCA, obtain space for the object from alloca(). (CVS 6702) (check-in: c7c0c58e47 user: drh tags: trunk) | |
| 17:10 | Added assert to verify winMutex system is inited before "static" mutexes are used. (CVS 6701) (check-in: b126013b5a user: shane tags: trunk) | |
| 17:06 | Ensure that "static" mutexes are deleted on shutdown so that they are not leaked across restarts. (CVS 6700) (check-in: 4e75897ee1 user: shane tags: trunk) | |
| 16:53 | Fix compiler warnings with MSVC build. (CVS 6699) (check-in: 0791588520 user: shane tags: trunk) | |
| 16:42 | Fix a couple of Windows only issues with test scripts. (CVS 6698) (check-in: 0f6bc5e1ba user: shane tags: trunk) | |

| 17:16 | Fix the ".genfkey" command of the CLI so that it does not leak memory if sqlite3_realloc() fails. Ticket #3891. (CVS 6696) (check-in: a028d69c70 user: drh tags: trunk) | |
|
2009-05-30

| 14:16 | Fix for ticket #3887. Other unrelated bits of code cleanup in the expr.c source module. (CVS 6693) (check-in: 00e7250f11 user: drh tags: trunk) | |
| 10:46 | In vacuum.c use "PagerIsMemdb(X)" instead of "PagerFile(X)->pMethods==0". (CVS 6692) (check-in: 874295ce71 user: danielk1977 tags: trunk) | |
|
2009-05-29
| ||
| 19:00 | Enhance the sqlite3VdbeGetOp() routine so that it always returns a pointer to VdbeOp, even following an OOM fault. This simplifies error handling in callers. Cleanup to the column cache logic and the expr.c source module. (CVS 6691) (check-in: ede06dacdf user: drh tags: trunk) | |
| 14:39 | Refinements in expression handling logic that have resulted from recent structural testing. (CVS 6690) (check-in: bd89f2c29b user: drh tags: trunk) | |
| 11:57 | Still more refinements to the hasHotJournal() fix of ticket #3883. (CVS 6689) (check-in: 726b425e43 user: drh tags: trunk) | |
| 10:55 | The hasHotJournal() fix of check-in (6687) causes some minor problems in various alternative operating modes, such as locking_mode=EXCLUSIVE. This additional patch attempts to fix those concerns. Ticket #3883. (CVS 6688) (check-in: a2ba61d927 user: drh tags: trunk) | |
| 00:30 | Modify the hasHotJournal() routine to return a false-positive if it is unable to open the journal file to check its header due to a race condition. Processing downstream of hasHotJournal() already knows how to deal with false-positives. Ticket #3883. (CVS 6687) (check-in: d6b5d8e1ab user: drh tags: trunk) | |
|
2009-05-28

| 14:34 | Fix a NULL pointer dereference following an OOM error in the column name resolver. (CVS 6685) (check-in: 3b46142532 user: drh tags: trunk) | |
| 12:49 | Make sure the column name resolver does not try to duplicate Expr.u.zToken when the Expr.u.iValue union member is the element being used. (CVS 6684) (check-in: 376ecf0d87 user: drh tags: trunk) | |
| 11:05 | Workaround the need for internal API sqlite3BtreeCursorDb(). It was only being used for an assert() statement, which can be done differently. (CVS 6683) (check-in: 5904af6e6d user: danielk1977 tags: trunk) | |
| 01:00 | Additional refinements to Expr handling. Restore compression of trigger expressions. Change Expr.zToken to Expr.u.zToken and added Expr.u.iValue. Remove an unnecessary ExprDup from CHECK constraint processing. And so forth. (CVS 6682) (check-in: 4ac2bdfbb4 user: drh tags: trunk) | |
|
2009-05-27
| ||
| 10:31 | Simplifications to the Expr object: Remove Expr.span completely and convert Expr.token into a char* Expr.zToken. Also simplify the Token object by removing the Token.dyn and Token.quoted fields. (CVS 6681) (check-in: 7cb1c3ba07 user: drh tags: trunk) | |

| 14:17 | Fix the rtree test module so that it works even if the ext/ subfolder is omitted from the tree. (CVS 6679) (check-in: 086206e1f5 user: drh tags: trunk) | |
| 12:40 | Update the configure script for version 3.6.14.2. (CVS 6678) (check-in: 58373119b7 user: drh tags: branch_3_6_14) | |

| 11:46 | When pinning a temp register after it is reused by the column cache, make sure all instances of that register in the cache are pinned so that the register is never reused for a different purpose. Ticket #3879. (CVS 6676) (check-in: 5f358e6371 user: drh tags: trunk) | |
| 11:46 | Add a test case for ticket #3879. (CVS 6675) (check-in: 5b9b66f47b user: danielk1977 tags: trunk) | |

| 21:59 | Additional clarification of the 3rd parameter to sqlite3_create_function(). Documentation change only; no changes to code. Ticket #3875. (CVS 6674) (check-in: dd75e376e8 user: drh tags: trunk) | |
| 11:08 | In the previous, the upper bound on the number of function arguments is 127, not 255. Ticket #3876 (CVS 6673) (check-in: 4fe4c5fac5 user: drh tags: trunk) | |
| 11:07 | Correct and clarify the documentation on the third parameter to sqlite3_create_function(). (CVS 6672) (check-in: 6b7929ed36 user: drh tags: trunk) | |
