11:14 | Update the built-in SQLite to the latest 3.40.0 alpha version that includes all performance enhancements and bug fixes. check-in: 4aa7837505 user: drh tags: trunk | |
11:13 | Update to a still newer version of SQLite 3.40.0 alpha that compiles without warnings on Mac ARM64. Closed-Leaf check-in: 6ff6d49521 user: drh tags: busted-build | |
10:59 | Remove the -D_HAVE_SQLITE_CONFIG_H option from the build of SQLite. We haven't had the config.h file for SQLite, so this should be a harmless change. check-in: 2522366fc7 user: drh tags: busted-build | |
10:47 | Update the built-in SQLite to the latest 3.40.0 alpha version that includes all bug fixes and performance enhancements. check-in: c7dc188478 user: drh tags: busted-build | |

14:40 | Fix a comment typo. check-in: db8b14c57a user: drh tags: trunk | |
2022-10-23
| ||
06:48 | Code maintenance for the `copybtn.js' script: Remove global data, reference DOM elements by function-binding instead of by id (that is possibly reused for the short-lived tooltip), and normalize variable names and string quoting style. check-in: d5f6621527 user: florian tags: trunk | |

So we use only LockFile() and ** UnlockFile(). ** ** LockFile() prevents not just writing but also reading by other processes. ** A SHARED_LOCK is obtained by locking a single randomly-chosen ** byte out of a specific range of bytes. The lock byte is obtained at ** random so two separate readers can probably access the file at the ** same time, unless they are unlucky and choose the same lock byte. ** An EXCLUSIVE_LOCK is obtained by locking all bytes in the range. ** There can only be one writer. A RESERVED_LOCK is obtained by locking ** a single byte of the file that is designated as the reserved lock byte. ** A PENDING_LOCK is obtained by locking a designated byte different from ** the RESERVED_LOCK byte. ** ** On WinNT/2K/XP systems, LockFileEx() and UnlockFileEx() are available, ** which means we can use reader/writer locks. When reader/writer locks ** are used, the lock is placed on the same range of bytes that is used ** for probabilistic locking in Win95/98/ME. Hence, the locking scheme ** will support two or more Win95 readers or two or more WinNT readers. ** But a single Win95 reader will lock out all WinNT readers and a single ** WinNT reader will lock out all other Win95 readers. ** ** The following #defines specify the range of bytes used for locking. ** SHARED_SIZE is the number of bytes available in the pool from which ** a random byte is selected for a shared lock. The pool of bytes for ** shared locks begins at SHARED_FIRST. ** ** The same locking strategy and ** byte ranges are used for Unix. This leaves open the possibility of having ** clients on win95, winNT, and unix all talking to the same shared file ** and all locking correctly. To do so would require that samba (or whatever ** tool is being used for file sharing) implements locks correctly between ** windows and unix. I'm guessing that isn't likely to happen, but by ** using the same locking range we are at least open to the possibility. ** ** Locking in windows is manditory. For this reason, we cannot store ** actual data in the bytes used for locking. The pager never allocates ** the pages involved in locking therefore. SHARED_SIZE is selected so ** that all locks will fit on a single page even at the minimum page size. ** PENDING_BYTE defines the beginning of the locks. By default PENDING_BYTE ** is set high so that we don't have to allocate an unused page except ** for very large databases. But one should test the page skipping logic ** by setting PENDING_BYTE low and running the entire regression suite. ** ** Changing the value of PENDING_BYTE results in a subtly incompatible ** file format.

In the text that follows, the operands of the subsequent ** OP_SeekGE opcode are denoted as SeekOP.P1 through SeekOP.P4. Only ** the P1, P2 and P5 operands of this opcode are also used, and are called ** This.P1, This.P2 and This.P5. ** ** This opcode helps to optimize IN operators on a multi-column index ** where the IN operator is on the later terms of the index by avoiding ** unnecessary seeks on the btree, substituting steps to the next row ** of the b-tree instead. A correct answer is obtained if this opcode ** is omitted or is a no-op. ** ** The SeekGE.P3 and SeekGE.P4 operands identify an unpacked key which ** is the desired entry that we want the cursor SeekGE.P1 to be pointing ** to. Call this SeekGE.P3/P4 row the "target". ** ** If the SeekGE.P1 cursor is not currently pointing to a valid row, ** then this opcode is a no-op and control passes through into the OP_SeekGE. ** ** If the SeekGE.P1 cursor is pointing to a valid row, then that row ** might be the target row, or it might be near and slightly before the ** target row, or it might be after the target row. If the cursor is ** currently before the target row, then this opcode attempts to position ** the cursor on or after the target row by invoking sqlite3BtreeStep() ** on the cursor between 1 and This.P1 times. ** ** The This.P5 parameter is a flag that indicates what to do if the ** cursor ends up pointing at a valid row that is past the target ** row. If This.P5 is false (0) then a jump is made to SeekGE.P2. If ** This.P5 is true (non-zero) then a jump is made to This.P2. The P5==0 ** case occurs when there are no inequality constraints to the right of ** the IN constraing. The jump to SeekGE.P2 ends the loop. The P5!=0 case ** occurs when there are inequality constraints to the right of the IN ** operator. In that case, the This.P2 will point either directly to or ** to setup code prior to the OP_IdxGT or OP_IdxGE opcode that checks for ** loop terminate. ** ** Possible outcomes from this opcode:<ol> ** ** <li> If the cursor is initally not pointed to any valid row, then ** fall through into the subsequent OP_SeekGE opcode. ** ** <li> If the cursor is left pointing to a row that is before the target ** row, even after making as many as This.P1 calls to ** sqlite3BtreeNext(), then also fall through into OP_SeekGE. ** ** <li> If the cursor is left pointing at the target row, either because it ** was at the target row to begin with or because one or more ** sqlite3BtreeNext() calls moved the cursor to the target row, ** then jump to This.P2.., ** ** <li> If the cursor started out before the target row and a call to ** to sqlite3BtreeNext() moved the cursor off the end of the index ** (indicating that the target row definitely does not exist in the ** btree) then jump to SeekGE.P2, ending the loop. ** ** <li> If the cursor ends up on a valid row that is past the target row ** (indicating that the target row does not exist in the btree) then ** jump to SeekOP.P2 if This.P5==0 or to This.P2 if This.P5>0. ** </ol> */ case OP_SeekScan: { VdbeCursor *pC; int res; int nStep; UnpackedRecord r; assert( pOp[1].opcode==OP_SeekGE ); /* If pOp->p5 is clear, then pOp->p2 points to the first instruction past the ** OP_IdxGT that follows the OP_SeekGE.
