Merge in all the trunk enhancements of the previous 7 months. The LIKE optimization has stopped working when there is an ESCAPE - that problem will be addressed in a subsequent check-in. (Leaf check-in: 8d2a1cca61 user: drh tags: est_count_pragma)
16:23
Use the updated Win32 VFS semantics for winOpen from check-in [5d03c738e9] for WinRT, et al, as well. (check-in: 2c03d8b8f0 user: mistachkin tags: trunk)
12:52
Partial backout of check-in [e0af9a904076]. It turns out we do need some extra space at the end of the record blob as an overrun area to use when decoding a maliciously malformed record. (check-in: 403b88a894 user: drh tags: trunk)
11:09
Cherrypick [ec37ad6d08] into this branch. With this patch, if SQLITE_SHARED_MAPPING is defined at build-time SQLite will use a single memory mapping for multiple connections to the same database file within a single process. (check-in: c7a5880d6d user: dan tags: begin-concurrent)
10:49
Merge latest trunk changes into this branch. (check-in: 307b802e86 user: dan tags: begin-concurrent)
00:24
Update the configure script so that it looks for tclsh8.7 ahead of tclsh8.6. (check-in: 0a12915b37 user: drh tags: trunk)

21:37
Fix a potential null-pointer dereference and crash in the case where one thread is calling sqlite3_column_text() and another thread is calling sqlite3_step() on the same prepared statement at the same instant. (check-in: ee1382a363 user: drh tags: trunk)
18:53
Remove the internal sqlite3CodeOnce() interface, replacing it with a direct call to sqlite3VdbeAddOp0(v,OP_Once). Slightly smaller and faster. (check-in: c3774c6a5f user: drh tags: trunk)
18:46
Makefile changes to support building winsqlite3.dll using STDCALL rather than CDECL. (check-in: 5e892d6093 user: mistachkin tags: trunk)

18:51
Add the --export-sql and --export-db options to the fuzzcheck utility program. (check-in: 760af44551 user: drh tags: trunk)
17:46
Fix a typo in the --help screen of the fuzzcheck utility. (check-in: b6ae61fe3b user: drh tags: trunk)
01:15
Futher simplifications to json1.c. Also an obscure bug-fix in the initial output of json_tree() when using a path to an object contained within an array. (check-in: fcb1e327a6 user: drh tags: trunk)
00:21
Fix json_set() so that it can overwrite a value that was previously overwritten during the same call. (check-in: 0f16041647 user: drh tags: trunk)

20:38
Fix to payload size overflow detection in the cellSizePtr() change of the previous check-in. (check-in: 7609744014 user: drh tags: trunk)
19:51
Size reduction and substantial performance increase for cellSizePtr(). (check-in: bc8bbf3207 user: drh tags: trunk)
14:30
Tune the query planner to be more aggressive about using automatic indexes on views and subqueries for which there is not opportunity to declare a persistent schema index. (check-in: 41de1643bf user: drh tags: trunk)
03:22
Disable shared memory operations using the unix-nolock VFS. (check-in: 10a6e51049 user: drh tags: trunk)

2008-09-22
17:54
Get rid of all of the compiler magic associated with SQLITE_EXPERIMENTAL and SQLITE_DEPRECATED. It was causing more problems than it was solving. Ticket #3395 et al. (CVS 5732) (check-in: bc040073c7 user: drh tags: trunk)
17:22
Fix a memory leak that can follow a malloc failure in sqlite3_initialize. (CVS 5731) (check-in: 118dc0ba08 user: danielk1977 tags: trunk)
11:46
Add instrumentation to os_unix.c to test that a return value of SQLITE_FULL from an xSync() callback is handled correctly. (CVS 5730) (check-in: 7bd2da93c6 user: danielk1977 tags: trunk)
10:44
Version 3.6.3 (CVS 5729) (check-in: 1634fd223d user: drh tags: trunk, release)
06:13
Remove unused macro Release() from vdbe.c. (CVS 5728) (check-in: 915679431a user: danielk1977 tags: trunk)
