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. +** +** Additional information can be found in the doc/jsonb.md file of the +** canonical SQLite source tree. */ #ifndef SQLITE_OMIT_JSON /* #include "sqliteInt.h" */ +/* JSONB element types +*/ +#define JSONB_NULL 0 /* "null" */ +#define JSONB_TRUE 1 /* "true" */ +#define JSONB_FALSE 2 /* "false" */ +#define JSONB_INT 3 /* integer acceptable to JSON and SQL */ +#define JSONB_INT5 4 /* integer in 0x000 notation */ +#define JSONB_FLOAT 5 /* float acceptable to JSON and SQL */ +#define JSONB_FLOAT5 6 /* float with JSON5 extensions */ +#define JSONB_TEXT 7 /* Text compatible with both JSON and SQL */ +#define JSONB_TEXTJ 8 /* Text with JSON escapes */ +#define JSONB_TEXT5 9 /* Text with JSON-5 escape */ +#define JSONB_TEXTRAW 10 /* SQL text that needs escaping for JSON */ +#define JSONB_ARRAY 11 /* An array */ +#define JSONB_OBJECT 12 /* An object */ + +/* Human-readable names for the JSONB values.

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. */ static void jsonValidFunc( sqlite3_context *ctx, @@ -202276,73 +207698,128 @@ static void jsonValidFunc( sqlite3_value **argv ){ JsonParse *p; /* The parse */ - UNUSED_PARAMETER(argc); - if( sqlite3_value_type(argv[0])==SQLITE_NULL ) return; - p = jsonParseCached(ctx, argv, 0); - if( p==0 || p->oom ){ - sqlite3_result_error_nomem(ctx); - sqlite3_free(p); - }else{ - sqlite3_result_int(ctx, p->nErr==0 && p->hasNonstd==0); - if( p->nErr ) jsonParseFree(p); + u8 flags = 1; + u8 res = 0; + if( argc==2 ){ + i64 f = sqlite3_value_int64(argv[1]); + if( f<1 || f>15 ){ + sqlite3_result_error(ctx, "FLAGS parameter to json_valid() must be" + " between 1 and 15", -1); + return; + } + flags = f & 0x0f; } + switch( sqlite3_value_type(argv[0]) ){ + case SQLITE_NULL: { +#ifdef SQLITE_LEGACY_JSON_VALID + /* Incorrect legacy behavior was to return FALSE for a NULL input */ + sqlite3_result_int(ctx, 0); +#endif + return; + } + case SQLITE_BLOB: { + if( jsonFuncArgMightBeBinary(argv[0]) ){ + if( flags & 0x04 ){ + /* Superficial checking only - accomplished by the + ** jsonFuncArgMightBeBinary() call above. */ + res = 1; + }else if( flags & 0x08 ){ + /* Strict checking.
