The order in which the changes related to +** a single table are stored is undefined. +** +** Following a successful call to this function, it is the responsibility of +** the caller to eventually free the buffer that *ppChangeset points to using +** [sqlite3_free()]. +** +**

Changeset Generation

+** +** Once a table has been attached to a session object, the session object +** records the primary key values of all new rows inserted into the table. +** It also records the original primary key and other column values of any +** deleted or updated rows. For each unique primary key value, data is only +** recorded once - the first time a row with said primary key is inserted, +** updated or deleted in the lifetime of the session. +** +** There is one exception to the previous paragraph: when a row is inserted, +** updated or deleted, if one or more of its primary key columns contain a +** NULL value, no record of the change is made. +** +** The session object therefore accumulates two types of records - those +** that consist of primary key values only (created when the user inserts +** a new record) and those that consist of the primary key values and the +** original values of other table columns (created when the users deletes +** or updates a record). +** +** When this function is called, the requested changeset is created using +** both the accumulated records and the current contents of the database +** file. Specifically: +** +** +** +** This means, amongst other things, that if a row is inserted and then later +** deleted while a session object is active, neither the insert nor the delete +** will be present in the changeset. Or if a row is deleted and then later a +** row with the same primary key values inserted while a session object is +** active, the resulting changeset will contain an UPDATE change instead of +** a DELETE and an INSERT. +** +** When a session object is disabled (see the [sqlite3session_enable()] API), +** it does not accumulate records when rows are inserted, updated or deleted. +** This may appear to have some counter-intuitive effects if a single row +** is written to more than once during a session. For example, if a row +** is inserted while a session object is enabled, then later deleted while +** the same session object is disabled, no INSERT record will appear in the +** changeset, even though the delete took place while the session was disabled. +** Or, if one field of a row is updated while a session is disabled, and +** another field of the same row is updated while the session is enabled, the +** resulting changeset will contain an UPDATE change that updates both fields. +*/ +int sqlite3session_changeset( + sqlite3_session *pSession, /* Session object */ + int *pnChangeset, /* OUT: Size of buffer at *ppChangeset */ + void **ppChangeset /* OUT: Buffer containing changeset */ +); + +/* +** CAPI3REF: Load The Difference Between Tables Into A Session +** +** If it is not already attached to the session object passed as the first +** argument, this function attaches table zTbl in the same manner as the +** [sqlite3session_attach()] function.

UPDATE Changes
+** For each UPDATE change, this function checks if the target database +** contains a row with the same primary key value (or values) as the +** original row values stored in the changeset. If it does, and the values +** stored in all non-primary key columns also match the values stored in +** the changeset the row is updated within the target database. +** +** If a row with matching primary key values is found, but one or more of +** the non-primary key fields contains a value different from an original +** row value stored in the changeset, the conflict-handler function is +** invoked with [SQLITE_CHANGESET_DATA] as the second argument. Since +** UPDATE changes only contain values for non-primary key fields that are +** to be modified, only those fields need to match the original values to +** avoid the SQLITE_CHANGESET_DATA conflict-handler callback. +** +** If no row with matching primary key values is found in the database, +** the conflict-handler function is invoked with [SQLITE_CHANGESET_NOTFOUND] +** passed as the second argument. +** +** If the UPDATE operation is attempted, but SQLite returns +** SQLITE_CONSTRAINT, the conflict-handler function is invoked with +** [SQLITE_CHANGESET_CONSTRAINT] passed as the second argument. +** This includes the case where the UPDATE operation is attempted after +** an earlier call to the conflict handler function returned +** [SQLITE_CHANGESET_REPLACE]. +**

+** +** Non-streaming functions that accept changesets (or patchsets) as input +** require that the entire changeset be stored in a single buffer in memory. +** Similarly, those that return a changeset or patchset do so by returning +** a pointer to a single large buffer allocated using sqlite3_malloc(). +** Normally this is convenient. However, if an application running in a +** low-memory environment is required to handle very large changesets, the +** large contiguous memory allocations required can become onerous. +** +** In order to avoid this problem, instead of a single large buffer, input +** is passed to a streaming API functions by way of a callback function that +** the sessions module invokes to incrementally request input data as it is +** required. In all cases, a pair of API function parameters such as +** +**

+**        void *pIn,
+**
+** +** Each time the xInput callback is invoked by the sessions module, the first +** argument passed is a copy of the supplied pIn context pointer. The second +** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no +** error occurs the xInput method should copy up to (*pnData) bytes of data +** into the buffer and set (*pnData) to the actual number of bytes copied +** before returning SQLITE_OK. If the input is completely exhausted, (*pnData) +** should be set to zero to indicate this. Or, if an error occurs, an SQLite +** error code should be returned. In all cases, if an xInput callback returns +** an error, all processing is abandoned and the streaming API function +** returns a copy of the error code to the caller. +** +** In the case of sqlite3changeset_start_strm(), the xInput callback may be +** invoked by the sessions module at any point during the lifetime of the +** iterator. If such an xInput callback returns an error, the iterator enters +** an error state, whereby all subsequent calls to iterator functions +** immediately fail with the same error code as returned by xInput. +** +** Similarly, streaming API functions that return changesets (or patchsets) +** return them in chunks by way of a callback function instead of via a +** pointer to a single large buffer.

For undefined and NULL values, the field consists +** only of the single type byte. For other types of values, the type byte +** is followed by: +** +** Text values: +** A varint containing the number of bytes in the value (encoded using +** UTF-8). Followed by a buffer containing the UTF-8 representation +** of the text value. There is no nul terminator. +** +** Blob values: +** A varint containing the number of bytes in the value, followed by +** a buffer containing the value itself. +** +** Integer values: +** An 8-byte big-endian integer value. +** +** Real values: +** An 8-byte big-endian IEEE 754-2008 real value. +** +** Varint values are encoded in the same way as varints in the SQLite +** record format. +** +** CHANGESET FORMAT: +** +** A changeset is a collection of DELETE, UPDATE and INSERT operations on +** one or more tables. Operations on a single table are grouped together, +** but may occur in any order (i.e. deletes, updates and inserts are all +** mixed together). +** +** Each group of changes begins with a table header: +** +** 1 byte: Constant 0x54 (capital 'T') +** Varint: Number of columns in the table. +** nCol bytes: 0x01 for PK columns, 0x00 otherwise. +** N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated. +** +** Followed by one or more changes to the table. +** +** 1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09). +** 1 byte: The "indirect-change" flag. +** old.* record: (delete and update only) +** new.* record: (insert and update only) +** +** The "old.*" and "new.*" records, if present, are N field records in the +** format described above under "RECORD FORMAT", where N is the number of +** columns in the table. The i'th field of each record is associated with +** the i'th column of the table, counting from left to right in the order +** in which columns were declared in the CREATE TABLE statement. +** +** The new.* record that is part of each INSERT change contains the values +** that make up the new row. Similarly, the old.* record that is part of each +** DELETE change contains the values that made up the row that was deleted +** from the database. In the changeset format, the records that are part +** of INSERT or DELETE changes never contain any undefined (type byte 0x00) +** fields. +** +** Within the old.* record associated with an UPDATE change, all fields +** associated with table columns that are not PRIMARY KEY columns and are +** not modified by the UPDATE change are set to "undefined". Other fields +** are set to the values that made up the row before the UPDATE that the +** change records took place. Within the new.* record, fields associated +** with table columns modified by the UPDATE change contain the new +** values. Fields associated with table columns that are not modified +** are set to "undefined". +** +** PATCHSET FORMAT: +** +** A patchset is also a collection of changes. It is similar to a changeset, +** but leaves undefined those fields that are not useful if no conflict +** resolution is required when applying the changeset. +** +** Each group of changes begins with a table header: +** +** 1 byte: Constant 0x50 (capital 'P') +** Varint: Number of columns in the table. +** nCol bytes: 0x01 for PK columns, 0x00 otherwise. +** N bytes: Unqualified table name (encoded using UTF-8). Nul-terminated. +** +** Followed by one or more changes to the table. +** +** 1 byte: Either SQLITE_INSERT (0x12), UPDATE (0x17) or DELETE (0x09). +** 1 byte: The "indirect-change" flag. +** single record: (PK fields for DELETE, PK and modified fields for UPDATE, +** full record for INSERT). +** +** As in the changeset format, each field of the single record that is part +** of a patchset change is associated with the correspondingly positioned +** table column, counting from left to right within the CREATE TABLE +** statement. +** +** For a DELETE change, all fields within the record except those associated +** with PRIMARY KEY columns are set to "undefined". The PRIMARY KEY fields +** contain the values identifying the row to delete. +** +** For an UPDATE change, all fields except those associated with PRIMARY KEY +** columns and columns that are modified by the UPDATE are set to "undefined". +** PRIMARY KEY fields contain the values identifying the table row to update, +** and fields associated with modified columns contain the new column values. +** +** The records associated with INSERT changes are in the same format as for +** changesets.

Changeset Generation

+** +** Once a table has been attached to a session object, the session object +** records the primary key values of all new rows inserted into the table. +** It also records the original primary key and other column values of any +** deleted or updated rows. For each unique primary key value, data is only +** recorded once - the first time a row with said primary key is inserted, +** updated or deleted in the lifetime of the session. +** +** There is one exception to the previous paragraph: when a row is inserted, +** updated or deleted, if one or more of its primary key columns contain a +** NULL value, no record of the change is made. +** +** The session object therefore accumulates two types of records - those +** that consist of primary key values only (created when the user inserts +** a new record) and those that consist of the primary key values and the +** original values of other table columns (created when the users deletes +** or updates a record). +** +** When this function is called, the requested changeset is created using +** both the accumulated records and the current contents of the database +** file. Specifically: +** +**
    +**
  • For each record generated by an insert, the database is queried +** for a row with a matching primary key. If one is found, an INSERT +** change is added to the changeset. If no such row is found, no change +** is added to the changeset. +** +**
  • For each record generated by an update or delete, the database is +** queried for a row with a matching primary key. If such a row is +** found and one or more of the non-primary key fields have been +** modified from their original values, an UPDATE change is added to +** the changeset. Or, if no such row is found in the table, a DELETE +** change is added to the changeset. If there is a row with a matching +** primary key in the database, but all fields contain their original +** values, no change is added to the changeset. +**
+** +** This means, amongst other things, that if a row is inserted and then later +** deleted while a session object is active, neither the insert nor the delete +** will be present in the changeset. Or if a row is deleted and then later a +** row with the same primary key values inserted while a session object is +** active, the resulting changeset will contain an UPDATE change instead of +** a DELETE and an INSERT. +** +** When a session object is disabled (see the [sqlite3session_enable()] API), +** it does not accumulate records when rows are inserted, updated or deleted. +** This may appear to have some counter-intuitive effects if a single row +** is written to more than once during a session. For example, if a row +** is inserted while a session object is enabled, then later deleted while +** the same session object is disabled, no INSERT record will appear in the +** changeset, even though the delete took place while the session was disabled. +** Or, if one field of a row is updated while a session is disabled, and +** another field of the same row is updated while the session is enabled, the +** resulting changeset will contain an UPDATE change that updates both fields. +*/ +int sqlite3session_changeset( + sqlite3_session *pSession, /* Session object */ + int *pnChangeset, /* OUT: Size of buffer at *ppChangeset */ + void **ppChangeset /* OUT: Buffer containing changeset */ +); + +/* +** CAPI3REF: Load The Difference Between Tables Into A Session +** +** If it is not already attached to the session object passed as the first +** argument, this function attaches table zTbl in the same manner as the +** [sqlite3session_attach()] function.

    +**
  • Has the same name, +**

INSERT Changes
+** For each INSERT change, an attempt is made to insert the new row into +** the database. +** +** If the attempt to insert the row fails because the database already +** contains a row with the same primary key values, the conflict handler +** function is invoked with the second argument set to +** [SQLITE_CHANGESET_CONFLICT]. +** +** If the attempt to insert the row fails because of some other constraint +** violation (e.g. NOT NULL or UNIQUE), the conflict handler function is +** invoked with the second argument set to [SQLITE_CHANGESET_CONSTRAINT]. +** This includes the case where the INSERT operation is re-attempted because +** an earlier call to the conflict handler function returned +** [SQLITE_CHANGESET_REPLACE]. +** +**

+** +** Non-streaming functions that accept changesets (or patchsets) as input +** require that the entire changeset be stored in a single buffer in memory. +** Similarly, those that return a changeset or patchset do so by returning +** a pointer to a single large buffer allocated using sqlite3_malloc(). +** Normally this is convenient. However, if an application running in a +** low-memory environment is required to handle very large changesets, the +** large contiguous memory allocations required can become onerous. +** +** In order to avoid this problem, instead of a single large buffer, input +** is passed to a streaming API functions by way of a callback function that +** the sessions module invokes to incrementally request input data as it is +** required. In all cases, a pair of API function parameters such as +** +** 
+**        int nChangeset,
+**        void *pChangeset,
+**
+** +** Is replaced by: +** +** 
+**        int (*xInput)(void *pIn, void *pData, int *pnData),
+**        void *pIn,
+**
+** +** Each time the xInput callback is invoked by the sessions module, the first +** argument passed is a copy of the supplied pIn context pointer. The second +** argument, pData, points to a buffer (*pnData) bytes in size. Assuming no +** error occurs the xInput method should copy up to (*pnData) bytes of data +** into the buffer and set (*pnData) to the actual number of bytes copied +** before returning SQLITE_OK. If the input is completely exhausted, (*pnData) +** should be set to zero to indicate this. Or, if an error occurs, an SQLite +** error code should be returned. In all cases, if an xInput callback returns +** an error, all processing is abandoned and the streaming API function +** returns a copy of the error code to the caller. +** +** In the case of sqlite3changeset_start_strm(), the xInput callback may be +** invoked by the sessions module at any point during the lifetime of the +** iterator. If such an xInput callback returns an error, the iterator enters +** an error state, whereby all subsequent calls to iterator functions +** immediately fail with the same error code as returned by xInput. +** +** Similarly, streaming API functions that return changesets (or patchsets) +** return them in chunks by way of a callback function instead of via a +** pointer to a single large buffer. In this case, a pair of parameters such +** as: +** +** 
+**        int *pnChangeset,
+**        void **ppChangeset,
+**
+** +** Is replaced by: +** +** 
+**        int (*xOutput)(void *pOut, const void *pData, int nData),
+**        void *pOut
+**
+** +** The xOutput callback is invoked zero or more times to return data to +** the application. The first parameter passed to each call is a copy of the +** pOut pointer supplied by the application. The second parameter, pData, +** points to a buffer nData bytes in size containing the chunk of output +** data being returned. If the xOutput callback successfully processes the +** supplied data, it should return SQLITE_OK to indicate success. Otherwise, +** it should return some other SQLite error code. In this case processing +** is immediately abandoned and the streaming API function returns a copy +** of the xOutput error code to the application. +** +** The sessions module never invokes an xOutput callback with the third +** parameter set to a value less than or equal to zero. Other than this, +** no guarantees are made as to the size of the chunks of data returned. +*/ +int sqlite3changeset_apply_strm( + sqlite3 *db, /* Apply change to "main" db of this handle */ + int (*xInput)(void *pIn, void *pData, int *pnData), /* Input function */ + void *pIn, /* First arg for xInput */ + int(*xFilter)( + void *pCtx, /* Copy of sixth arg to _apply() */ + const char *zTab /* Table name */ + ), + int(*xConflict)( + void *pCtx, /* Copy of sixth arg to _apply() */ + int eConflict, /* DATA, MISSING, CONFLICT, CONSTRAINT */ + sqlite3_changeset_iter *p /* Handle describing change and conflict */ + ), + void *pCtx /* First argument passed to xConflict */ +); +int sqlite3changeset_concat_strm( + int (*xInputA)(void *pIn, void *pData, int *pnData), + void *pInA, + int (*xInputB)(void *pIn, void *pData, int *pnData), + void *pInB, + int (*xOutput)(void *pOut, const void *pData, int nData), + void *pOut +); +int sqlite3changeset_invert_strm( + int (*xInput)(void *pIn, void *pData, int *pnData), + void *pIn, + int (*xOutput)(void *pOut, const void *pData, int nData), + void *pOut +); +int sqlite3changeset_start_strm( + sqlite3_changeset_iter **pp, + int (*xInput)(void *pIn, void *pData, int *pnData), + void *pIn +); +int sqlite3session_changeset_strm( + sqlite3_session *pSession, + int (*xOutput)(void *pOut, const void *pData, int nData), + void *pOut +); +int sqlite3session_patchset_strm( + sqlite3_session *pSession, + int (*xOutput)(void *pOut, const void *pData, int nData), + void *pOut +); +int sqlite3changegroup_add_strm(sqlite3_changegroup*, + int (*xInput)(void *pIn, void *pData, int *pnData), + void *pIn +); +int sqlite3changegroup_output_strm(sqlite3_changegroup*, + int (*xOutput)(void *pOut, const void *pData, int nData), + void *pOut +); + + +/* +** Make sure we can call this stuff from C++. +*/ +#ifdef __cplusplus +} +#endif + +#endif /* !defined(__SQLITESESSION_H_) && defined(SQLITE_ENABLE_SESSION) */ + +/******** End of sqlite3session.h *********/ +/******** Begin file fts5.h *********/ /* ** 2014 May 31 ** @@ -8252,11 +9749,13 @@ struct Fts5PhraseIter { ** ...
