// against the open file represented by the [sqlite3_file] object.
|

//
|
|
// If the [sqlite3_vfs.xOpen] method sets the sqlite3_file.pMethods element
|
|
// to a non-NULL pointer, then the sqlite3_io_methods.xClose method
|
|
// may be invoked even if the [sqlite3_vfs.xOpen] reported that it failed. The
|
|
// only way to prevent a call to xClose following a failed [sqlite3_vfs.xOpen]
|
|
// is for the [sqlite3_vfs.xOpen] to set the sqlite3_file.pMethods element
|
|
// to NULL.
|
|
//
|
|
// The flags argument to xSync may be one of [SQLITE_SYNC_NORMAL] or
|
|
// [SQLITE_SYNC_FULL]. The first choice is the normal fsync().
|
|
// The second choice is a Mac OS X style fullsync. The [SQLITE_SYNC_DATAONLY]
|
|
// flag may be ORed in to indicate that only the data of the file
|
|
// and not its inode needs to be synced.
|
|
//
|
|
// The integer values to xLock() and xUnlock() are one of
|
|
// <ul>
|

// <li> [SQLITE_LOCK_NONE],
|
|
// <li> [SQLITE_LOCK_SHARED],

// xLock() upgrades the database file lock. In other words, xLock() moves the
|
|
// database file lock in the direction NONE toward EXCLUSIVE. The argument to
|
|
// xLock() is always on of SHARED, RESERVED, PENDING, or EXCLUSIVE, never
|
|
// SQLITE_LOCK_NONE. If the database file lock is already at or above the
|
|
// requested lock, then the call to xLock() is a no-op.
|
|
// xUnlock() downgrades the database file lock to either SHARED or NONE.

|
//
|
|
// If the lock is already at or below the requested lock state, then the call
|
|
//
|
|
// to xUnlock() is a no-op.
|
|
// The xCheckReservedLock() method checks whether any database connection,
|
|
// either in this process or in some other process, is holding a RESERVED,
|
|
// PENDING, or EXCLUSIVE lock on the file. It returns true

// if such a lock exists and false otherwise.

|
// The xFileControl() method is a generic interface that allows custom
|
|
// VFS implementations to directly control an open file using the
|
|
// [sqlite3_file_control()] interface. The second "op" argument is an
|
|
// integer opcode. The third argument is a generic pointer intended to
|
|
// point to a structure that may contain arguments or space in which to
|
|
// write return values. Potential uses for xFileControl() might be
|
|
// functions to enable blocking locks with timeouts, to change the
|
|
// locking strategy (for example to use dot-file locks), to inquire
|
|
// about the status of a lock, or to break stale locks. The SQLite
|
|
// core reserves all opcodes less than 100 for its own use.
|
|
// A [file control opcodes | list of opcodes] less than 100 is available.
|
|
// Applications that define a custom xFileControl method should use opcodes

// greater than 100 to avoid conflicts. VFS implementations should
|
|
// return [SQLITE_NOTFOUND] for file control opcodes that they do not
|
|
// recognize.

// The xSectorSize() method returns the sector size of the
|
|
// device that underlies the file. The sector size is the
|
|
// minimum write that can be performed without disturbing
|
|
// other bytes in the file. The xDeviceCharacteristics()
|
|
// method returns a bit vector describing behaviors of the

// The VFS interface is sometimes extended by adding new methods onto

|
|
// is incremented. The iVersion value started out as 1 in

// SQLite [version 3.5.0] on [dateof:3.5.0], then increased to 2
|
|
// with SQLite [version 3.7.0] on [dateof:3.7.0], and then increased
|
|
// to 3 with SQLite [version 3.7.6] on [dateof:3.7.6]. Additional fields
|
|
// may be appended to the sqlite3_vfs object and the iVersion value
|
|
// may increase again in future versions of SQLite.
|
|
// Note that due to an oversight, the structure

|
|
// the pNext pointer. The [sqlite3_vfs_register()]
|
|
// and [sqlite3_vfs_unregister()] interfaces manage this list

|
// the open of a journal file a no-op. Writes to this journal would

|
// also be no-ops, and any attempt to read the journal would return
|
|
// SQLITE_IOERR. Or the implementation might recognize that a database

|
// file will be doing page-aligned sector reads and writes in a random
|
|
// order and set up its I/O subsystem accordingly.

|
|
// <li> [SQLITE_OPEN_EXCLUSIVE]

// deleted when it is closed. ^The [SQLITE_OPEN_DELETEONCLOSE]
|
|
// will be set for TEMP databases and their journals, transient
|
|
// databases, and subjournals.
|
|
//
|
|
// ^The [SQLITE_OPEN_EXCLUSIVE] flag is always used in conjunction
|
|
// with the [SQLITE_OPEN_CREATE] flag, which are both directly
|
|
// analogous to the O_EXCL and O_CREAT flags of the POSIX open()
|
|
// API. The SQLITE_OPEN_EXCLUSIVE flag, when paired with the
|
|
// SQLITE_OPEN_CREATE, is used to indicate that file should always
|
|
// be created, and that it is an error if it already exists.
|
|
// It is <i>not</i> used to indicate the file should be opened

|
|
// ^At least szOsFile bytes of memory are allocated by SQLite
|

// to hold the [sqlite3_file] structure passed as the third

// allocate the structure; it should just fill it in. Note that

|
// the xOpen method must set the sqlite3_file.pMethods to either
|
|
// a valid [sqlite3_io_methods] object or to NULL. xOpen must do
|
|
// this even if the open fails. SQLite expects that the sqlite3_file.pMethods

|
|
// test whether a file is readable and writable, or [SQLITE_ACCESS_READ]

|
|
// flag is never actually used and is not implemented in the built-in

// directory. The xAccess method returns [SQLITE_OK] on success or some
|
|
// non-zero error code if there is an I/O error or if the name of
|
|
// the file given in the second argument is illegal. If SQLITE_OK

|
|
// ^SQLite will always allocate at least mxPathname+1 bytes for the

// The xRandomness() function attempts to return nBytes bytes
|
|
// of good-quality randomness into zOut. The return value is
|
|
// the actual number of bytes of randomness obtained.
|
|
// The xSleep() method causes the calling thread to sleep for at
|
|
// least the number of microseconds given. ^The xCurrentTime()
|
|
// method returns a Julian Day Number for the current date and time as
|
|
// a floating point value.
|
|
// ^The xCurrentTimeInt64() method returns, as an integer, the Julian
|
|
// Day Number multiplied by 86400000 (the number of milliseconds in

|
// a 24-hour day).
|
|
// ^SQLite will use the xCurrentTimeInt64() method to get the current

|
// By creating an instance of this object

|
|
// during configuration, an application can specify an alternative

|
// dynamic memory needs.
|
|
//
|
|
// Note that SQLite comes with several [built-in memory allocators]
|
|
// that are perfectly adequate for the overwhelming majority of applications
|
|
// and that this object is only useful to a tiny minority of applications
|
|
// with specialized memory allocation requirements. This object is
|
|
// also used during testing of SQLite in order to specify an alternative
|
|
// memory allocator that simulates memory out-of-memory conditions in
|
|
// order to verify that SQLite recovers gracefully from such
|
|
// conditions.
|
|
//
|
|
// The xMalloc, xRealloc, and xFree methods must work like the
|
|
// malloc(), realloc() and free() functions from the standard C library.
|

// ^SQLite guarantees that the second argument to

// xSize should return the allocated size of a memory allocation
|
|
// previously obtained from xMalloc or xRealloc. The allocated size
|
|
// is always at least as big as the requested size but may be larger.
|
|
//
|
|
// The xRoundup method returns what would be the allocated size of
|
|
// a memory allocation given a particular requested size. Most memory

// of 8. Some allocators round up to a larger multiple or to a power of 2.
|
|
// Every memory allocation request coming in through [sqlite3_malloc()]

|
// changeset recorded (the "local" changeset). Then, a changeset based
|
|
// on S0 is received from another site (the "remote" changeset) and
|
|
// applied to the database. The database is then in state
|
|
// (S1+"remote"), where the exact state depends on any conflict
|
|
// resolution decisions (OMIT or REPLACE) made while applying "remote".
|
|
// Rebasing a changeset is to update it to take those conflict
|
|
// resolution decisions into account, so that the same conflicts
|
|
// do not have to be resolved elsewhere in the network.
|
|
//
|
|
// For example, if both the local and remote changesets contain an

|
// conflict resolution was "OMIT", then the local changeset is modified
|
|
// to instead contain:
|
|
//
|
|
// UPDATE t1 SET b = 'v2' WHERE a=1;
|
|
//
|

//
|
|
// <dl>
|
|
// <dt>Local INSERT<dd>
|
|
//
|

// This may only conflict with a remote INSERT. If the conflict

// changeset. Or, if the conflict resolution was REPLACE, add

// nothing to the rebased changeset.

//
|
|
// <dt>Local DELETE<dd>

|
// This may conflict with a remote UPDATE or DELETE. In both cases the

|
// only possible resolution is OMIT. If the remote operation was a

|
// DELETE, then add no change to the rebased changeset. If the remote

|
// operation was an UPDATE, then the old.* fields of change are updated
|
|
// to reflect the new.* values in the UPDATE.

|
//

// <dt>Local UPDATE<dd>
|
|
//
|

// This may conflict with a remote UPDATE or DELETE. If it conflicts

|
// with a DELETE, and the conflict resolution was OMIT, then the update
|
|
// is changed into an INSERT. Any undefined values in the new.* record
|
|
// from the update change are filled in using the old.* values from

|
// the conflicting DELETE. Or, if the conflict resolution was REPLACE,

|
// the UPDATE change is simply omitted from the rebased changeset.

|
// into the rebased changeset with updates to columns also updated by

|
// the conflicting remote UPDATE removed. If this means no columns would

//
|

// <ul>

|
// it is theoretically possible, though very unlikely,
|
|
// that an inopertune power failure could leave the journal
|
|
// in a state which would cause damage to the database
|
|
// when it is rolled back.
|
|
//
|
|
// FULL The journal is synced twice before writes begin on the
|
|
// database (with some additional information - the nRec field
|
|
// of the journal header - being written in between the two
|
|
// syncs). If we assume that writing a
|
|
// single disk sector is atomic, then this mode provides
|
|
// assurance that the journal will not be corrupted to the
|
|
// point of causing damage to the database during rollback.
|
|
//
|
|
// EXTRA This is like FULL except that is also syncs the directory
|
|
// that contains the rollback journal after the rollback
|
|
// journal is unlinked.
|
|
//
|
|
// The above is for a rollback-journal mode. For WAL mode, OFF continues
|
|
// to mean that no syncs ever occur. NORMAL means that the WAL is synced
|
|
// prior to the start of checkpoint and that the database file is synced
|
|
// at the conclusion of the checkpoint if the entire content of the WAL
|
|
// was written back into the database. But no sync operations occur for
|
|
// an ordinary commit in NORMAL mode with WAL. FULL means that the WAL
|
|
// file is synced following each commit operation, in addition to the
|
|
// syncs associated with NORMAL. There is no difference between FULL
|
|
// and EXTRA for WAL mode.
|
|
//
|
|
// Do not confuse synchronous=FULL with SQLITE_SYNC_FULL. The
|
|
// SQLITE_SYNC_FULL macro means to use the MacOSX-style full-fsync
|
|
// using fcntl(F_FULLFSYNC). SQLITE_SYNC_NORMAL means to do an
|
|
// ordinary fsync() call. There is no difference between SQLITE_SYNC_FULL
|
|
// and SQLITE_SYNC_NORMAL on platforms other than MacOSX. But the

|
// synchronous=FULL versus synchronous=NORMAL setting determines when

// SHARED lock on the database file. Immediately after obtaining
|
|
// the SHARED lock, the file-system is checked for a hot-journal,
|
|
// which is played back if present. Following any hot-journal
|
|
// rollback, the contents of the cache are validated by checking
|
|
// the 'change-counter' field of the database file header and
|
|
// discarded if they are found to be invalid.
|
|
//
|
|
// 2. If the pager is running in exclusive-mode, and there are currently
|
|
// no outstanding references to any pages, and is in the error state,
|
|
// then an attempt is made to clear the error state by discarding
|
|
// the contents of the page cache and rolling back any open journal
|
|
// file.
|
|
//
|
|
// If everything is successful, SQLITE_OK is returned. If an IO error
|
|
// occurs while locking the database, checking for a hot-journal file or
|
|
// rolling back a journal file, the IO error code is returned.

// to sqlite3ThreadJoin() is likely to block. Cases that are likely to

// block provoke debugging output.

// This routine walks an expression tree and resolves references to

|
// table columns and result-set columns. At the same time, do error
|
|
// checking on function usage and set a flag if any aggregate functions
|
|
// are seen.
|
|
//
|
|
// To resolve table columns references we look for nodes (or subtrees) of the
|
|
// form X.Y.Z or Y.Z or just Z where
|
|
//
|
|
// X: The name of a database. Ex: "main" or "temp" or
|
|
// the symbolic name assigned to an ATTACH-ed database.
|
|
//
|
|
// Y: The name of a table in a FROM clause. Or in a trigger
|
|
// one of the special names "old" or "new".
|
|
//
|
|
// Z: The name of a column in table Y.
|
|
//
|
|
// The node at the root of the subtree is modified as follows:
|
|
//
|
|
// Expr.op Changed to TK_COLUMN
|
|
// Expr.pTab Points to the Table object for X.Y
|
|
// Expr.iColumn The column index in X.Y. -1 for the rowid.
|
|
// Expr.iTable The VDBE cursor number for X.Y
|
|
//
|
|
// To resolve result-set references, look for expression nodes of the
|
|
// form Z (with no X and Y prefix) where the Z matches the right-hand
|
|
// size of an AS clause in the result-set of a SELECT. The Z expression
|
|
// is replaced by a copy of the left-hand side of the result-set expression.
|
|
// Table-name and function resolution occurs on the substituted expression
|
|
// tree. For example, in:
|
|
//
|
|
// SELECT a+b AS x, c+d AS y FROM t1 ORDER BY x;
|
|
//
|
|
// The "x" term of the order by is replaced by "a+b" to render:
|
|
//
|
|
// SELECT a+b AS x, c+d AS y FROM t1 ORDER BY a+b;
|
|
//
|
|
// Function calls are checked to make sure that the function is
|
|
// defined and that the correct number of arguments are specified.
|
|
// If the function is an aggregate function, then the NC_HasAgg flag is
|
|
// set and the opcode is changed from TK_FUNCTION to TK_AGG_FUNCTION.
|
|
// If an expression contains aggregate functions then the EP_Agg
|
|
// property on the expression is set.
|
|
//
|
|
// An error message is left in pParse if anything is amiss. The number
|
|
// if errors is returned.

// This function is used by the implementation of the IN (...) operator.

// The pX parameter is the expression on the RHS of the IN operator, which
|
|
// might be either a list of expressions or a subquery.
|
|
//
|
|
// The job of this routine is to find or create a b-tree object that can
|
|
// be used either to test for membership in the RHS set or to iterate through
|
|
// all members of the RHS set, skipping duplicates.
|
|
//
|
|
// A cursor is opened on the b-tree object that is the RHS of the IN operator
|
|
// and the *piTab parameter is set to the index of that cursor.
|
|
//
|
|
// The returned value of this function indicates the b-tree type, as follows:
|
|
//
|
|
// IN_INDEX_ROWID - The cursor was opened on a database table.
|
|
// IN_INDEX_INDEX_ASC - The cursor was opened on an ascending index.
|
|
// IN_INDEX_INDEX_DESC - The cursor was opened on a descending index.
|
|
// IN_INDEX_EPH - The cursor was opened on a specially created and
|
|
// populated epheremal table.
|
|
// IN_INDEX_NOOP - No cursor was allocated. The IN operator must be
|
|
// implemented as a sequence of comparisons.
|
|
//
|
|
// An existing b-tree might be used if the RHS expression pX is a simple
|
|
// subquery such as:
|
|
//
|
|
// SELECT <column1>, <column2>... FROM <table>
|
|
//
|
|
// If the RHS of the IN operator is a list or a more complex subquery, then
|
|
// an ephemeral table might need to be generated from the RHS and then
|
|
// pX->iTable made to point to the ephemeral table instead of an
|
|
// existing table. In this case, the creation and initialization of the
|
|
// ephmeral table might be put inside of a subroutine, the EP_Subrtn flag
|
|
// will be set on pX and the pX->y.sub fields will be set to show where
|
|
// the subroutine is coded.
|
|
//
|
|
// The inFlags parameter must contain, at a minimum, one of the bits
|
|
// IN_INDEX_MEMBERSHIP or IN_INDEX_LOOP but not both. If inFlags contains
|
|
// IN_INDEX_MEMBERSHIP, then the generated table will be used for a fast
|
|
// membership test. When the IN_INDEX_LOOP bit is set, the IN index will
|
|
// be used to loop over all values of the RHS of the IN operator.
|
|
//
|
|
// When IN_INDEX_LOOP is used (and the b-tree will be used to iterate
|
|
// through the set members) then the b-tree must not contain duplicates.
|
|
// An epheremal table will be created unless the selected columns are guaranteed
|
|
// to be unique - either because it is an INTEGER PRIMARY KEY or due to
|
|
// a UNIQUE constraint or index.
|
|
//
|
|
// When IN_INDEX_MEMBERSHIP is used (and the b-tree will be used
|
|
// for fast set membership tests) then an epheremal table must
|
|
// be used unless <columns> is a single INTEGER PRIMARY KEY column or an
|
|
// index can be found with the specified <columns> as its left-most.
|
|
//
|
|
// If the IN_INDEX_NOOP_OK and IN_INDEX_MEMBERSHIP are both set and
|
|
// if the RHS of the IN operator is a list (not a subquery) then this
|
|
// routine might decide that creating an ephemeral b-tree for membership
|
|
// testing is too expensive and return IN_INDEX_NOOP. In that case, the
|
|
// calling routine should implement the IN operator using a sequence
|
|
// of Eq or Ne comparison operations.
|
|
//
|
|
// When the b-tree is being used for membership tests, the calling function
|
|
// might need to know whether or not the RHS side of the IN operator
|
|
// contains a NULL. If prRhsHasNull is not a NULL pointer and
|
|
// if there is any chance that the (...) might contain a NULL value at
|
|
// runtime, then a register is allocated and the register number written
|
|
// to *prRhsHasNull. If there is no chance that the (...) contains a
|
|
// NULL value, then *prRhsHasNull is left unchanged.
|
|
//
|
|
// If a register is allocated and its location stored in *prRhsHasNull, then
|
|
// the value in that register will be NULL if the b-tree contains one or more
|
|
// NULL values, and it will be some non-NULL value if the b-tree contains no
|
|
// NULL values.
|
|
//
|
|
// If the aiMap parameter is not NULL, it must point to an array containing
|
|
// one element for each column returned by the SELECT statement on the RHS
|
|
// of the IN(...) operator. The i'th entry of the array is populated with the
|
|
// offset of the index column that matches the i'th column returned by the
|
|
// SELECT. For example, if the expression and selected index are:
|
|
//
|
|
// (?,?,?) IN (SELECT a, b, c FROM t1)
|
|
// CREATE INDEX i1 ON t1(b, c, a);
|
|
//
|

// then aiMap[] is populated with {2, 0, 1}.

// is omitted.
|

//
|

// For the pSelect parameter holds the values to be inserted for the
|
|
// first two forms shown above. A VALUES clause is really just short-hand
|
|
// for a SELECT statement that omits the FROM clause and everything else
|
|
// that follows. If the pSelect parameter is NULL, that means that the
|
|
// DEFAULT VALUES form of the INSERT statement is intended.
|
|
//
|
|
// The code generated follows one of four templates. For a simple
|
|
// insert with data coming from a single-row VALUES clause, the code executes
|
|
// once straight down through. Pseudo-code follows (we call this
|
|
// the "1st template"):
|
|
//
|
|
// open write cursor to <table> and its indices
|
|
// put VALUES clause expressions into registers
|
|
// write the resulting record into <table>
|
|
// cleanup
|
|
//
|
|
// The three remaining templates assume the statement is of the form
|
|
//
|
|
// INSERT INTO <table> SELECT ...
|
|
//
|
|
// If the SELECT clause is of the restricted form "SELECT * FROM <table2>" -
|
|
// in other words if the SELECT pulls all columns from a single table
|
|
// and there is no WHERE or LIMIT or GROUP BY or ORDER BY clauses, and
|
|
// if <table2> and <table1> are distinct tables but have identical
|
|
// schemas, including all the same indices, then a special optimization
|
|
// is invoked that copies raw records from <table2> over to <table1>.
|
|
// See the xferOptimization() function for the implementation of this
|
|
// template. This is the 2nd template.
|
|
//
|
|
// open a write cursor to <table>
|
|
// open read cursor on <table2>
|
|
// transfer all records in <table2> over to <table>
|
|
// close cursors
|
|
// foreach index on <table>
|
|
// open a write cursor on the <table> index
|
|
// open a read cursor on the corresponding <table2> index
|
|
// transfer all records from the read to the write cursors
|
|
// close cursors
|
|
// end foreach
|
|
//
|
|
// The 3rd template is for when the second template does not apply
|
|
// and the SELECT clause does not read from <table> at any time.
|
|
// The generated code follows this template:
|
|
//
|
|
// X <- A
|
|
// goto B
|
|
// A: setup for the SELECT
|
|
// loop over the rows in the SELECT
|
|
// load values into registers R..R+n
|
|
// yield X
|
|
// end loop
|
|
// cleanup after the SELECT
|
|
// end-coroutine X
|
|
// B: open write cursor to <table> and its indices
|
|
// C: yield X, at EOF goto D
|
|
// insert the select result into <table> from R..R+n
|
|
// goto C
|
|
// D: cleanup
|
|
//
|
|
// The 4th template is used if the insert statement takes its
|
|
// values from a SELECT but the data is being inserted into a table
|
|
// that is also read as part of the SELECT. In the third form,
|
|
// we have to use an intermediate table to store the results of
|
|
// the select. The template is like this:
|
|
//
|
|
// X <- A
|
|
// goto B
|
|
// A: setup for the SELECT
|
|
// loop over the tables in the SELECT
|
|
// load value into register R..R+n
|
|
// yield X
|
|
// end loop
|
|
// cleanup after the SELECT
|
|
// end co-routine R
|
|
// B: open temp table
|
|
// L: yield X, at EOF goto M
|

// Generate code to do constraint checks prior to an INSERT or an UPDATE

|

//
|
|
// The regNewData parameter is the first register in a range that contains
|
|
// the data to be inserted or the data after the update. There will be
|
|
// pTab->nCol+1 registers in this range. The first register (the one
|
|
// that regNewData points to) will contain the new rowid, or NULL in the
|
|
// case of a WITHOUT ROWID table. The second register in the range will
|
|
// contain the content of the first table column. The third register will
|
|
// contain the content of the second table column. And so forth.
|
|
//
|
|
// The regOldData parameter is similar to regNewData except that it contains
|
|
// the data prior to an UPDATE rather than afterwards. regOldData is zero
|
|
// for an INSERT. This routine can distinguish between UPDATE and INSERT by
|
|
// checking regOldData for zero.
|
|
//
|
|
// For an UPDATE, the pkChng boolean is true if the true primary key (the
|
|
// rowid for a normal table or the PRIMARY KEY for a WITHOUT ROWID table)
|
|
// might be modified by the UPDATE. If pkChng is false, then the key of
|
|
// the iDataCur content table is guaranteed to be unchanged by the UPDATE.
|
|
//
|
|
// For an INSERT, the pkChng boolean indicates whether or not the rowid
|
|
// was explicitly specified as part of the INSERT statement. If pkChng
|
|
// is zero, it means that the either rowid is computed automatically or
|
|
// that the table is a WITHOUT ROWID table and has no rowid. On an INSERT,
|
|
// pkChng will only be true if the INSERT statement provides an integer
|
|
// value for either the rowid column or its INTEGER PRIMARY KEY alias.
|
|
//
|
|
// The code generated by this routine will store new index entries into
|
|
// registers identified by aRegIdx[]. No index entry is created for
|
|
// indices where aRegIdx[i]==0. The order of indices in aRegIdx[] is
|
|
// the same as the order of indices on the linked list of indices
|
|
// at pTab->pIndex.
|
|
//
|
|
// (2019-05-07) The generated code also creates a new record for the
|
|
// main table, if pTab is a rowid table, and stores that record in the
|
|
// register identified by aRegIdx[nIdx] - in other words in the first
|
|
// entry of aRegIdx[] past the last index. It is important that the
|
|
// record be generated during constraint checks to avoid affinity changes
|
|
// to the register content that occur after constraint checks but before
|
|
// the new record is inserted.
|
|
//
|
|
// The caller must have already opened writeable cursors on the main
|
|
// table and all applicable indices (that is to say, all indices for which
|
|
// aRegIdx[] is not zero). iDataCur is the cursor for the main table when
|
|
// inserting or updating a rowid table, or the cursor for the PRIMARY KEY
|
|
// index when operating on a WITHOUT ROWID table. iIdxCur is the cursor
|
|
// for the first index in the pTab->pIndex list. Cursors for other indices
|
|
// are at iIdxCur+N for the N-th element of the pTab->pIndex list.
|
|
//
|
|
// This routine also generates code to check constraints. NOT NULL,
|
|
// CHECK, and UNIQUE constraints are all checked. If a constraint fails,
|
|
// then the appropriate action is performed. There are five possible
|
|
// actions: ROLLBACK, ABORT, FAIL, REPLACE, and IGNORE.
|
|
//
|
|
// Constraint type Action What Happens
|
|
// --------------- ---------- ----------------------------------------
|
|
// any ROLLBACK The current transaction is rolled back and
|
|
// sqlite3_step() returns immediately with a
|
|
// return code of SQLITE_CONSTRAINT.
|
|
//
|
|
// any ABORT Back out changes from the current command
|
|
// only (do not do a complete rollback) then
|
|
// cause sqlite3_step() to return immediately
|
|
// with SQLITE_CONSTRAINT.
|
|
//
|
|
// any FAIL Sqlite3_step() returns immediately with a
|
|
// return code of SQLITE_CONSTRAINT. The
|
|
// transaction is not rolled back and any
|
|
// changes to prior rows are retained.
|
|
//
|
|
// any IGNORE The attempt in insert or update the current
|
|
// row is skipped, without throwing an error.
|
|
// Processing continues with the next row.
|
|
// (There is an immediate jump to ignoreDest.)
|
|
//
|
|
// NOT NULL REPLACE The NULL value is replace by the default
|
|
// value for that column. If the default value
|
|
// is NULL, the action is the same as ABORT.
|
|
//
|
|
// UNIQUE REPLACE The other row that conflicts with the row
|
|
// being inserted is removed.
|
|
//
|
|
// CHECK REPLACE Illegal. The results in an exception.
|
|
//
|
|
// Which action to take is determined by the overrideError parameter.
|
|
// Or if overrideError==OE_Default, then the pParse->onError parameter
|
|
// is used. Or if pParse->onError==OE_Default then the onError value
|
|
// for the constraint is used.

// The VACUUM command is used to clean up the database,

// in PostgreSQL. The VACUUM command works as follows:
|
|
//
|
|
// (1) Create a new transient database file
|
|
// (2) Copy all content from the database being vacuumed into
|
|
// the new transient database file
|
|
// (3) Copy content from the transient database back into the
|
|
// original database.
|
|
//
|
|
// The transient database requires temporary disk space approximately
|
|
// equal to the size of the original database. The copy operation of
|
|
// step (3) requires additional temporary disk space approximately equal
|
|
// to the size of the original database for the rollback journal.
|
|
// Hence, temporary disk space that is approximately 2x the size of the
|
|
// original database is required. Every page of the database is written
|
|
// approximately 3 times: Once for step (2) and twice for step (3).
|
|
// Two writes per page are required in step (3) because the original
|
|
// database content must be written into the rollback journal prior to
|
|
// overwriting the database with the vacuumed content.
|
|
//
|
|
// Only 1x temporary space and only 1x writes would be required if
|
|
// the copy of step (3) were replaced by deleting the original database
|
|
// and renaming the transient database as the original. But that will
|
|
// not work if other processes are attached to the original database.
|
|
// And a power loss in between deleting the original and renaming the
|
|
// transient would cause the database file to appear to be deleted
|
|
// following reboot.

// Generate the beginning of the loop used for WHERE clause processing.
|
|
// The return value is a pointer to an opaque structure that contains
|
|
// information needed to terminate the loop. Later, the calling routine
|
|
// should invoke sqlite3WhereEnd() with the return value of this function
|
|
// in order to complete the WHERE clause processing.
|
|
//
|
|
// If an error occurs, this routine returns NULL.
|
|
//
|
|
// The basic idea is to do a nested loop, one loop for each table in
|
|
// the FROM clause of a select. (INSERT and UPDATE statements are the
|
|
// same as a SELECT with only a single table in the FROM clause.) For
|
|
// example, if the SQL is this:
|
|
//
|
|
// SELECT * FROM t1, t2, t3 WHERE ...;
|
|
//
|
|
// Then the code generated is conceptually like the following:
|
|
//
|
|
// foreach row1 in t1 do \ Code generated
|
|
// foreach row2 in t2 do |-- by sqlite3WhereBegin()
|
|
// foreach row3 in t3 do /
|
|
// ...
|
|
// end \ Code generated
|
|
// end |-- by sqlite3WhereEnd()
|
|
// end /
|
|
//
|
|
// Note that the loops might not be nested in the order in which they
|
|
// appear in the FROM clause if a different order is better able to make
|
|
// use of indices. Note also that when the IN operator appears in
|
|
// the WHERE clause, it might result in additional nested loops for
|
|
// scanning through all values on the right-hand side of the IN.
|
|
//
|
|
// There are Btree cursors associated with each table. t1 uses cursor
|
|
// number pTabList->a[0].iCursor. t2 uses the cursor pTabList->a[1].iCursor.
|
|
// And so forth. This routine generates code to open those VDBE cursors
|
|
// and sqlite3WhereEnd() generates the code to close them.
|
|
//
|
|
// The code that sqlite3WhereBegin() generates leaves the cursors named
|
|
// in pTabList pointing at their appropriate entries. The [...] code
|
|
// can use OP_Column and OP_Rowid opcodes on these cursors to extract
|
|
// data from the various tables of the loop.
|
|
//
|
|
// If the WHERE clause is empty, the foreach loops must each scan their
|
|
// entire tables. Thus a three-way join is an O(N^3) operation. But if
|
|
// the tables have indices and there are terms in the WHERE clause that
|
|
// refer to those indices, a complete table scan can be avoided and the
|
|
// code will run much faster. Most of the work of this routine is checking
|
|
// to see if there are indices that can be used to speed up the loop.
|
|
//
|
|
// Terms of the WHERE clause are also used to limit which rows actually
|
|
// make it to the "..." in the middle of the loop. After each "foreach",
|
|
// terms of the WHERE clause that use only terms in that loop and outer
|
|
// loops are evaluated and if false a jump is made around all subsequent
|
|
// inner loops (or around the "..." if the test occurs within the inner-
|
|
// most loop)
|
|
//
|
|
// # OUTER JOINS
|
|
//
|
|
// An outer join of tables t1 and t2 is conceptally coded as follows:
|
|
//
|
|
// foreach row1 in t1 do
|
|
// flag = 0
|
|
// foreach row2 in t2 do
|
|
// start:
|
|
// ...
|
|
// flag = 1
|
|
// end
|
|
// if flag==0 then
|
|
// move the row2 cursor to a null row
|
|
// goto start
|
|
// fi
|
|
// end
|
|
//
|
|
// # ORDER BY CLAUSE PROCESSING
|
|
//
|
|
// pOrderBy is a pointer to the ORDER BY clause (or the GROUP BY clause
|
|
// if the WHERE_GROUPBY flag is set in wctrlFlags) of a SELECT statement
|
|
// if there is one. If there is no ORDER BY clause or if this routine
|
|
// is called from an UPDATE or DELETE statement, then pOrderBy is NULL.
|
|
//
|
|
// The iIdxCur parameter is the cursor number of an index. If
|
|
// WHERE_OR_SUBCLAUSE is set, iIdxCur is the cursor number of an index
|
|
// to use for OR clause processing. The WHERE clause should use this
|
|
// specific cursor. If WHERE_ONEPASS_DESIRED is set, then iIdxCur is
|
|
// the first cursor in an array of cursors for all indices. iIdxCur should
|
|
// be used to compute the appropriate cursor depending on which index is
|
|
// used.

|

|

// To handle this case, the pseudo-code programs depicted above are modified

// slightly to be:
|
|
//
|
|
// ... loop started by sqlite3WhereBegin() ...
|

// delete eph table contents
|

// continue

|
|
// ...
|
|
//
|
|
// The new "continue" statement in the above jumps to the next iteration
|
|
// of the outer loop - the one started by sqlite3WhereBegin().
|
|
//
|
|
// The various GROUPS cases are implemented using the same patterns as
|
|
// ROWS. The VM code is modified slightly so that:
|
|
//
|
|
// 1. The else branch in the main loop is only taken if the row just
|
|
// added to the ephemeral table is the start of a new group. In
|
|
// other words, it becomes:
|
|
//
|
|
// ... loop started by sqlite3WhereBegin() ...
|
|
// if( new partition ){
|
|
// Gosub flush
|
|
// }
|
|
// Insert new row into eph table.
|

// if( first row of partition ){

// Rewind(csrEnd) ; Rewind(csrStart) ; Rewind(csrCurrent)
|
|
// regEnd = <expr2>
|
|
// regStart = <expr1>
|
|
// }else if( new group ){
|
|
// ...
|
|
// }
|
|
// }
|
|
//
|
|
// 2. Instead of processing a single row, each RETURN_ROW, AGGSTEP or
|
|
// AGGINVERSE step processes the current row of the relevant cursor and
|
|
// all subsequent rows belonging to the same group.
|
|
//
|
|
// RANGE window frames are a little different again. As for GROUPS, the
|
|
// main loop runs once per group only. And RETURN_ROW, AGGSTEP and AGGINVERSE
|
|
// deal in groups instead of rows. As for ROWS and GROUPS, there are three
|
|
// basic cases:
|
|
//
|
|
// RANGE BETWEEN <expr1> PRECEDING AND <expr2> FOLLOWING
|
|
//
|
|
// ... loop started by sqlite3WhereBegin() ...

//
|
|
// YYCODETYPE is the data type used to store the integer codes
|
|
// that represent terminal and non-terminal symbols.
|
|
// "unsigned char" is used if there are fewer than
|
|
// 256 symbols. Larger types otherwise.
|
|
// YYNOCODE is a number of type YYCODETYPE that is not used for
|
|
// any terminal or nonterminal symbol.
|
|
// YYFALLBACK If defined, this indicates that one or more tokens
|
|
// (also known as: "terminal symbols") have fall-back
|
|
// values which should be used if the original symbol
|
|
// would not parse. This permits keywords to sometimes
|
|
// be used as identifiers, for example.
|
|
// YYACTIONTYPE is the data type used for "action codes" - numbers
|
|
// that indicate what to do in response to the next
|
|
// token.
|
|
// sqlite3ParserTOKENTYPE is the data type used for minor type for terminal
|
|
// symbols. Background: A "minor type" is a semantic
|
|
// value associated with a terminal or non-terminal
|
|
// symbols. For example, for an "ID" terminal symbol,
|
|
// the minor type might be the name of the identifier.
|
|
// Each non-terminal can have a different minor type.
|
|
// Terminal symbols all have the same minor type, though.
|
|
// This macros defines the minor type for terminal
|
|
// symbols.
|
|
// YYMINORTYPE is the data type used for all minor types.
|
|
// This is typically a union of many types, one of
|
|
// which is sqlite3ParserTOKENTYPE. The entry in the union
|
|
// for terminal symbols is called "yy0".
|
|
// YYSTACKDEPTH is the maximum depth of the parser's stack. If
|
|
// zero the stack is dynamically sized using realloc()
|
|
// sqlite3ParserARG_SDECL A static variable declaration for the %extra_argument
|
|
// sqlite3ParserARG_PDECL A parameter declaration for the %extra_argument
|
|
// sqlite3ParserARG_PARAM Code to pass %extra_argument as a subroutine parameter
|
|
// sqlite3ParserARG_STORE Code to store %extra_argument into yypParser
|
|
// sqlite3ParserARG_FETCH Code to extract %extra_argument from yypParser
|
|
// sqlite3ParserCTX_* As sqlite3ParserARG_ except for %extra_context
|
|
// YYERRORSYMBOL is the code number of the error symbol. If not
|
|
// defined, then do no error processing.
|
|
// YYNSTATE the combined number of states.
|
|
// YYNRULE the number of rules in the grammar
|
|
// YYNTOKEN Number of terminal symbols
|
|
// YY_MAX_SHIFT Maximum value for shift actions
|
|
// YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
|
|
// YY_MAX_SHIFTREDUCE Maximum value for shift-reduce actions
|

// fts5YYCODETYPE is the data type used to store the integer codes
|
|
// that represent terminal and non-terminal symbols.
|
|
// "unsigned char" is used if there are fewer than
|
|
// 256 symbols. Larger types otherwise.
|
|
// fts5YYNOCODE is a number of type fts5YYCODETYPE that is not used for
|
|
// any terminal or nonterminal symbol.
|
|
// fts5YYFALLBACK If defined, this indicates that one or more tokens
|
|
// (also known as: "terminal symbols") have fall-back
|
|
// values which should be used if the original symbol
|
|
// would not parse. This permits keywords to sometimes
|
|
// be used as identifiers, for example.
|

// fts5YYACTIONTYPE is the data type used for "action codes" - numbers

// that indicate what to do in response to the next
|
|
// token.
|
|
// sqlite3Fts5ParserFTS5TOKENTYPE is the data type used for minor type for terminal
|
|
// symbols. Background: A "minor type" is a semantic
|
|
// value associated with a terminal or non-terminal
|
|
// symbols. For example, for an "ID" terminal symbol,
|
|
// the minor type might be the name of the identifier.
|
|
// Each non-terminal can have a different minor type.
|
|
// Terminal symbols all have the same minor type, though.
|

// This macros defines the minor type for terminal

|
// symbols.
|
|
// fts5YYMINORTYPE is the data type used for all minor types.
|
|
// This is typically a union of many types, one of
|
|
// which is sqlite3Fts5ParserFTS5TOKENTYPE. The entry in the union
|
|
// for terminal symbols is called "fts5yy0".
|
|
// fts5YYSTACKDEPTH is the maximum depth of the parser's stack. If
|
|
// zero the stack is dynamically sized using realloc()
|
|
// sqlite3Fts5ParserARG_SDECL A static variable declaration for the %extra_argument
|
|
// sqlite3Fts5ParserARG_PDECL A parameter declaration for the %extra_argument

// sqlite3Fts5ParserARG_PARAM Code to pass %extra_argument as a subroutine parameter
|
|
// sqlite3Fts5ParserARG_STORE Code to store %extra_argument into fts5yypParser
|
|
// sqlite3Fts5ParserARG_FETCH Code to extract %extra_argument from fts5yypParser
|
|
// sqlite3Fts5ParserCTX_* As sqlite3Fts5ParserARG_ except for %extra_context
|
|
// fts5YYERRORSYMBOL is the code number of the error symbol. If not
|
|
// defined, then do no error processing.
|
|
// fts5YYNSTATE the combined number of states.
|
|
// fts5YYNRULE the number of rules in the grammar
|
|
// fts5YYNFTS5TOKEN Number of terminal symbols
|
|
// fts5YY_MAX_SHIFT Maximum value for shift actions
|

// fts5YY_MIN_SHIFTREDUCE Minimum value for shift-reduce actions
|

// NOTES ON TRANSACTIONS:
|
|
//
|
|
// SQLite invokes the following virtual table methods as transactions are
|
|
// opened and closed by the user:
|
|
//
|
|
// xBegin(): Start of a new transaction.
|
|
// xSync(): Initial part of two-phase commit.
|
|
// xCommit(): Final part of two-phase commit.
|
|
// xRollback(): Rollback the transaction.
|
|
//
|
|
// Anything that is required as part of a commit that may fail is performed
|
|
// in the xSync() callback. Current versions of SQLite ignore any errors
|
|
// returned by xCommit().
|
|
//
|
|
// And as sub-transactions are opened/closed:
|
|
//
|
|
// xSavepoint(int S): Open savepoint S.
|
|
// xRelease(int S): Commit and close savepoint S.
|
|
// xRollbackTo(int S): Rollback to start of savepoint S.
|
|
//
|
|
// During a write-transaction the fts5_index.c module may cache some data
|
|
// in-memory. It is flushed to disk whenever xSync(), xRelease() or
|
|
// xSavepoint() is called. And discarded whenever xRollback() or xRollbackTo()
|
|
// is called.
|
|
//
|
|
// Additionally, if SQLITE_DEBUG is defined, an instance of the following
|
|
// structure is used to record the current transaction state. This information
|
|
// is not required, but it is used in the assert() statements executed by
|
