28 check-ins using file src/sqliteInt.h version 12aa1f62

2017-09-28
01:09
Indexes on expressions with a COLLATE clause are able to satisfy an ORDER BY with the same COLLATE clause. (check-in: 04130018 user: drh tags: trunk)
00:01
In two places, change the magic number -1 to its proper symbol XN_ROWID. (check-in: 80277d2f user: drh tags: trunk)
2017-09-27
16:51
Disable tests for the LIKE optimization when ICU is enabled, since the LIKE optimization only works for the built-in LIKE operator and ICU overrides the built-in. (check-in: f5ef2e1b user: drh tags: trunk)
2017-09-25
09:37
Add an extra snapshot related test case. (check-in: 24a95e14 user: dan tags: trunk)
2017-09-23
07:46
Experimental change so that snapshot transactions always lock the wal file - preventing writers or truncate-checkpointers from wrapping it. (Closed-Leaf check-in: d71eeaab user: dan tags: snapshots-lock-wal)
2017-09-22
16:23
Use the updated Win32 VFS semantics for winOpen from check-in [5d03c738e9] for WinRT, et al, as well. (check-in: 2c03d8b8 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: 403b88a8 user: drh tags: trunk)
00:24
Update the configure script so that it looks for tclsh8.7 ahead of tclsh8.6. (check-in: 0a12915b user: drh tags: trunk)
2017-09-21
20:43
In the Windows VFS, when trying to open a database file read/write, if it fails check to see if the file exists and is read-only and immediately fall back to a read-only open attempt, rather than running the AV retry loop. (check-in: 5d03c738 user: drh tags: trunk)
20:03
In the Windows VFS, do not emit an SQLITE_CANTOPEN error log message when falling back from SQLITE_OPEN_READWRITE to SQLITE_OPEN_READONLY. Wait until the open fails completely. (check-in: fa3f5bcc user: drh tags: trunk)
19:08
Fix harmless UB in the ICU extension. (check-in: 68e9a840 user: drh tags: trunk)
14:03
The sqlite3_snapshot_describe() interface useful for debugging snapshot logic. (Leaf check-in: 3fbfa9a8 user: drh tags: sqlite3_snapshot_describe)
13:11
Fix a potential use of an uninitialized pointer in RTree following an OOM error. (check-in: fd4ec0cd user: drh tags: trunk)
10:24
Fix a bug in tool/mksourceid.c: The mksourceid.c program was incorrectly including the "# Remove this line" line of the Fossil-generated "manifest" file in the SHA3 hash. That means that all SQLITE_SOURCE_IDs for trunk versions going back to check-in [30966d56] (2017-08-22) are incorrect. (check-in: 65765222 user: drh tags: trunk)
01:04
Revert one performance improvement changes from check-in [3b3e32d4cd07] as it was causing a reference to an uninitialized value. (check-in: f8b1c64d user: drh tags: trunk)
00:49
Fix the rendering of the P4_INTARRAY argument to the OP_IntegrityCk opcode in the output of EXPLAIN. (check-in: adc12c83 user: drh tags: trunk)
2017-09-20
18:47
Size and performance optimization on sqlite3VdbeMemGrow(). (check-in: 4b3f7eac user: drh tags: trunk)
18:07
The BLOB returned by sqlite3VdbeMemFromBtree() does not need to be zero-terminated. (check-in: e0af9a90 user: drh tags: trunk)
17:49
Small size and performance optimization in the bytecode engine. (check-in: 3b3e32d4 user: drh tags: trunk)
10:47
Improved resolution of large integer values in "CAST(x AS NUMERIC)". (check-in: 7f2bd4ff user: drh tags: trunk)
09:09
Updates to the "lemon.html" document received from Andy Goth. (check-in: 5b2002f3 user: drh tags: trunk)
2017-09-18
18:17
Add the sqlite3_mmap_warm() function as an extension in the ext/misc/mmapwarm.c source file. (check-in: 1b2de414 user: drh tags: trunk)
18:08
Fix a typo in the MSVC makefile. (Closed-Leaf check-in: 3235835b user: drh tags: mmap-warm)
16:28
Add extension "mmapwarm.c". Provides function sqlite3_mmap_warm(), used to "warm up" the memory mapping used by SQLite in mmap mode to access db file content. (check-in: d4a30b91 user: dan tags: mmap-warm)
13:16
Minor simplification of error message generation during compound query code generation. (check-in: a9447193 user: drh tags: trunk)
09:40
The out-of-bounds read on recovery fix of check-in [378afa16381a222a] caused problems for some corner-case error conditions. This alternative fix appears to work better. (check-in: 74f399d8 user: drh tags: trunk)
00:18
Fix the CSV virtual table extension so that it works when the default character is unsigned. (check-in: 42f07775 user: drh tags: trunk)
2017-09-17
19:45
Do not make the assumption (as check-in [4da49a95c0f07] incorrectly did) that the ExprList returned by sqlite3ExprListDup() would never be passed into sqlite3ExprListAppend(). Include a new test case that shows this sometimes does happen. (check-in: 29227d00 user: drh tags: trunk)
