+** File Locking Notes: (Mostly about windows but also some info for Unix)
+**
+** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
+** those functions are not available. 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. Depending on how it is changed, you might not notice
+** the incompatibility right away, even running a full regression test.
+** The default location of PENDING_BYTE is the first byte past the
+** 1GB boundary.

-** File Locking Notes: (Mostly about windows but also some info for Unix)
-**
-** We cannot use LockFileEx() or UnlockFileEx() on Win95/98/ME because
-** those functions are not available. 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. Depending on how it is changed, you might not notice
-** the incompatibility right away, even running a full regression test.
-** The default location of PENDING_BYTE is the first byte past the
-** 1GB boundary.

+**
+** P1 is normally a cursor on a btree for which the row decode cache is

+** The the btree row has fewer than P3 columns, then use P4 as the
+** datatype.
+**
+** If P1 is -1, then P3 is a register number and the datatype is taken
+** from the value in that register.
+**
+** P5 is a bitmask of data types. SQLITE_INTEGER is the least significant
+** (0x01) bit. SQLITE_FLOAT is the 0x02 bit. SQLITE_TEXT is 0x04.
+** SQLITE_BLOB is 0x08. SQLITE_NULL is 0x10.

+** The isOuterJoin column indicates that the replacement will occur into a
+** position in the parent that NULL-able due to an OUTER JOIN. Either the
+** target slot in the parent is the right operand of a LEFT JOIN, or one of
+** the left operands of a RIGHT JOIN. In either case, we need to potentially
+** bypass the substituted expression with OP_IfNullRow.
+**
+** Suppose the original expression is an integer constant. Even though the table
+** has the nullRow flag set, because the expression is an integer constant,
+** it will not be NULLed out. So instead, we insert an OP_IfNullRow opcode
+** that checks to see if the nullRow flag is set on the table. If the nullRow
+** flag is set, then the value in the register is set to NULL and the original
+** expression is bypassed. If the nullRow flag is not set, then the original
+** expression runs to populate the register.
+**
+** Example where this is needed:
+**
+** CREATE TABLE t1(a INTEGER PRIMARY KEY, b INT);
+** CREATE TABLE t2(x INT UNIQUE);
+**
+** SELECT a,b,m,x FROM t1 LEFT JOIN (SELECT 59 AS m,x FROM t2) ON b=x;
+**
+** When the subquery on the right side of the LEFT JOIN is flattened, we
+** have to add OP_IfNullRow in front of the OP_Integer that implements the

**
-** This SQLite extension implements JSON functions. The interface is
-** modeled after MySQL JSON functions:
-**
-** https://dev.mysql.com/doc/refman/5.7/en/json.html
+** SQLite JSON functions.
+**
+** This file began as an extension in ext/misc/json1.c in 2015. That
+** extension proved so useful that it has now been moved into the core.
+**
+** The original design stored all JSON as pure text, canonical RFC-8259.
+** Support for JSON-5 extensions was added with version 3.42.0 (2023-05-16).
+** All generated JSON text still conforms strictly to RFC-8259, but text
+** with JSON-5 extensions is accepted as input.
+**
+** Beginning with version 3.45.0 (circa 2024-01-01), these routines also
+** accept BLOB values that have JSON encoded using a binary representation
+** called "JSONB". The name JSONB comes from PostgreSQL, however the on-disk
+** format SQLite JSONB is completely different and incompatible with
+** PostgreSQL JSONB.
+**
+** Decoding and interpreting JSONB is still O(N) where N is the size of
+** the input, the same as text JSON. However, the constant of proportionality
+** for JSONB is much smaller due to faster parsing. The size of each
+** element in JSONB is encoded in its header, so there is no need to search
+** for delimiters using persnickety syntax rules. JSONB seems to be about
+** 3x faster than text JSON as a result. JSONB is also tends to be slightly
+** smaller than text JSON, by 5% or 10%, but there are corner cases where
+** JSONB can be slightly larger. So you are not far mistaken to say that
+** a JSONB blob is the same size as the equivalent RFC-8259 text.
+**
+**
+** THE JSONB ENCODING:
+**
+** Every JSON element is encoded in JSONB as a header and a payload.
+** The header is between 1 and 9 bytes in size. The payload is zero
+** or more bytes.
+**
+** The lower 4 bits of the first byte of the header determines the
+** element type:
+**
+** 0: NULL
+** 1: TRUE
+** 2: FALSE
+** 3: INT -- RFC-8259 integer literal
+** 4: INT5 -- JSON5 integer literal
+** 5: FLOAT -- RFC-8259 floating point literal
+** 6: FLOAT5 -- JSON5 floating point literal
+** 7: TEXT -- Text literal acceptable to both SQL and JSON
+** 8: TEXTJ -- Text containing RFC-8259 escapes
+** 9: TEXT5 -- Text containing JSON5 and/or RFC-8259 escapes
+** 10: TEXTRAW -- Text containing unescaped syntax characters
+** 11: ARRAY
+** 12: OBJECT
+**
+** The other three possible values (13-15) are reserved for future
+** enhancements.
+**
+** The upper 4 bits of the first byte determine the size of the header
+** and sometimes also the size of the payload. If X is the first byte
+** of the element and if X>>4 is between 0 and 11, then the payload
+** will be that many bytes in size and the header is exactly one byte
+** in size. Other four values for X>>4 (12-15) indicate that the header
+** is more than one byte in size and that the payload size is determined
+** by the remainder of the header, interpreted as a unsigned big-endian
+** integer.
+**
+** Value of X>>4 Size integer Total header size
+** ------------- -------------------- -----------------
+** 12 1 byte (0-255) 2
+** 13 2 byte (0-65535) 3
+** 14 4 byte (0-4294967295) 5
+** 15 8 byte (0-1.8e19) 9
+**
+** The payload size need not be expressed in its minimal form. For example,
+** if the payload size is 10, the size can be expressed in any of 5 different
+** ways: (1) (X>>4)==10, (2) (X>>4)==12 following by on 0x0a byte,
+** (3) (X>>4)==13 followed by 0x00 and 0x0a, (4) (X>>4)==14 followed by
+** 0x00 0x00 0x00 0x0a, or (5) (X>>4)==15 followed by 7 bytes of 0x00 and
+** a single byte of 0x0a. The shorter forms are preferred, of course, but
+** sometimes when generating JSONB, the payload size is not known in advance
+** and it is convenient to reserve sufficient header space to cover the
+** largest possible payload size and then come back later and patch up
+** the size when it becomes known, resulting in a non-minimal encoding.
+**
+** The value (X>>4)==15 is not actually used in the current implementation
+** (as SQLite is currently unable handle BLOBs larger than about 2GB)
+** but is included in the design to allow for future enhancements.
+**
+** The payload follows the header. NULL, TRUE, and FALSE have no payload and
+** their payload size must always be zero. The payload for INT, INT5,
+** FLOAT, FLOAT5, TEXT, TEXTJ, TEXT5, and TEXTROW is text. Note that the
+** "..." or '...' delimiters are omitted from the various text encodings.
+** The payload for ARRAY and OBJECT is a list of additional elements that
+** are the content for the array or object. The payload for an OBJECT
+** must be an even number of elements. The first element of each pair is
+** the label and must be of type TEXT, TEXTJ, TEXT5, or TEXTRAW.
+**
+** A valid JSONB blob consists of a single element, as described above.
+** Usually this will be an ARRAY or OBJECT element which has many more
+** elements as its content. But the overall blob is just a single element.
+**
+** Input validation for JSONB blobs simply checks that the element type
+** code is between 0 and 12 and that the total size of the element
+** (header plus payload) is the same as the size of the BLOB. If those
+** checks are true, the BLOB is assumed to be JSONB and processing continues.
+** Errors are only raised if some other miscoding is discovered during
+** processing.
**
-** For the time being, all JSON is stored as pure text. (We might add
-** a JSONB type in the future which stores a binary encoding of JSON in
-** a BLOB, but there is no support for JSONB in the current implementation.
-** This implementation parses JSON text at 250 MB/s, so it is hard to see
-** how JSONB might improve on that.)
+** Additional information can be found in the doc/jsonb.md file of the
+** canonical SQLite source tree.

** json_valid(JSON)
-**
-** Return 1 if JSON is a well-formed JSON string according to RFC-7159.
-** Return 0 otherwise.
+** json_valid(JSON, FLAGS)
+**
+** Check the JSON argument to see if it is well-formed. The FLAGS argument
+** encodes the various constraints on what is meant by "well-formed":
+**
+** 0x01 Canonical RFC-8259 JSON text
+** 0x02 JSON text with optional JSON-5 extensions
+** 0x04 Superficially appears to be JSONB
+** 0x08 Strictly well-formed JSONB
+**
+** If the FLAGS argument is omitted, it defaults to 1. Useful values for
+** FLAGS include:
+**
+** 1 Strict canonical JSON text
+** 2 JSON text perhaps with JSON-5 extensions
+** 4 Superficially appears to be JSONB
+** 5 Canonical JSON text or superficial JSONB
+** 6 JSON-5 text or superficial JSONB
+** 8 Strict JSONB
+** 9 Canonical JSON text or strict JSONB
+** 10 JSON-5 text or strict JSONB
+**
+** Other flag combinations are redundant. For example, every canonical
+** JSON text is also well-formed JSON-5 text, so FLAG values 2 and 3
+** are the same. Similarly, any input that passes a strict JSONB validation
+** will also pass the superficial validation so 12 through 15 are the same
+** as 8 through 11 respectively.
+**
+** This routine runs in linear time to validate text and when doing strict
+** JSONB validation. Superficial JSONB validation is constant time,
+** assuming the BLOB is already in memory. The performance advantage
+** of superficial JSONB validation is why that option is provided.
+** Application developers can choose to do fast superficial validation or
+** slower strict validation, according to their specific needs.
+**
+** Only the lower four bits of the FLAGS argument are currently used.
+** Higher bits are reserved for future expansion. To facilitate
+** compatibility, the current implementation raises an error if any bit
+** in FLAGS is set other than the lower four bits.
+**
+** The original circa 2015 implementation of the JSON routines in
+** SQLite only supported canonical RFC-8259 JSON text and the json_valid()
+** function only accepted one argument. That is why the default value
+** for the FLAGS argument is 1, since FLAGS=1 causes this routine to only
+** recognize canonical RFC-8259 JSON text as valid. The extra FLAGS
+** argument was added when the JSON routines were extended to support
+** JSON5-like extensions and binary JSONB stored in BLOBs.
+**
+** Return Values:
+**
+** * Raise an error if FLAGS is outside the range of 1 to 15.
+** * Return NULL if the input is NULL
+** * Return 1 if the input is well-formed.
+** * Return 0 if the input is not well-formed.

+** are used to store the tombstone rowids for rows contained in the
+** associated segments.
+**
+** The set of nHashPg tombstone hash pages associated with a single
+** segment together form a single hash table containing tombstone rowids.
+** To find the page of the hash on which a key might be stored:
+**
+** iPg = (rowid % nHashPg)
+**
+** Then, within page iPg, which has nSlot slots:
+**
+** iSlot = (rowid / nHashPg) % nSlot
+**
+** Each tombstone hash page begins with an 8 byte header:
+**
+** 1-byte: Key-size (the size in bytes of each slot). Either 4 or 8.
+** 1-byte: rowid-0-tombstone flag. This flag is only valid on the
+** first tombstone hash page for each segment (iPg=0). If set,
+** the hash table contains rowid 0. If clear, it does not.
+** Rowid 0 is handled specially.
+** 2-bytes: unused.
+** 4-bytes: Big-endian integer containing number of entries on page.
+**
+** Following this are nSlot 4 or 8 byte slots (depending on the key-size
+** in the first byte of the page header). The number of slots may be
+** determined based on the size of the page record and the key-size:
+**
+** nSlot = (nByte - 8) / key-size
