This is equivalent to a diff from 5df40564 to efa20f8e
2015-05-19
| ||
16:50 | Merge the ota-update branch with trunk. (check-in: 08e2864e user: dan tags: trunk) | |
16:26 | Add a comment for SQLITE_FCNTL_OTA to sqlite.h.in. (Closed-Leaf check-in: efa20f8e user: dan tags: ota-update) | |
16:22 | Allow OTA update state data to be stored in a database separate from the OTA update database. (check-in: 5af8db56 user: dan tags: ota-update) | |
14:14 | Merge latest trunk changes with this branch. (check-in: 6055a672 user: dan tags: ota-update) | |
2015-05-18
| ||
12:28 | Transitive constraints should only work if operands have compatible affinities and collating sequences. (check-in: 5df40564 user: drh tags: trunk) | |
12:18 | Use an ALWAY() on conditionals in the transitive constraint logic that are always true as far as we know. (Closed-Leaf check-in: 204e567f user: drh tags: transitive-constraints) | |
04:24 | Make a hard copy of the results of a subquery lest the result of the subquery be referenced after a change to the table that generated the subquery result. (check-in: 9c0d8090 user: drh tags: trunk) | |

The tables it expects to find are described in ** sqlite3ota.h. Essentially, for each table xyz in the target database ** that the user wishes to write to, a corresponding data_xyz table is ** created in the OTA database and populated with one row for each row to ** update, insert or delete from the target table. ** ** The update proceeds in three stages: ** ** 1) The database is updated. The modified database pages are written ** to a *-oal file. A *-oal file is just like a *-wal file, except ** that it is named "<database>-oal" instead of "<database>-wal". ** Because regular SQLite clients do not look for file named ** "<database>-oal", they go on using the original database in ** rollback mode while the *-oal file is being generated. ** ** During this stage OTA does not update the database by writing ** directly to the target tables. Instead it creates "imposter" ** tables using the SQLITE_TESTCTRL_IMPOSTER interface that it uses ** to update each b-tree individually. All updates required by each ** b-tree are completed before moving on to the next, and all ** updates are done in sorted key order. ** ** 2) The "<database>-oal" file is moved to the equivalent "<database>-wal" ** location using a call to rename(2). Before doing this the OTA ** module takes an EXCLUSIVE lock on the database file, ensuring ** that there are no other active readers. ** ** Once the EXCLUSIVE lock is released, any other database readers ** detect the new *-wal file and read the database in wal mode. At ** this point they see the new version of the database - including ** the updates made as part of the OTA update. ** ** 3) The new *-wal file is checkpointed. This proceeds in the same way ** as a regular database checkpoint, except that a single frame is ** checkpointed each time sqlite3ota_step() is called. If the OTA ** handle is closed before the entire *-wal file is checkpointed, ** the checkpoint progress is saved in the OTA database and the ** checkpoint can be resumed by another OTA client at some point in ** the future. ** ** POTENTIAL PROBLEMS ** ** The rename() call might not be portable. And OTA is not currently ** syncing the directory after renaming the file. ** ** When state is saved, any commit to the *-oal file and the commit to ** the OTA update database are not atomic. So if the power fails at the ** wrong moment they might get out of sync. As the main database will be ** committed before the OTA update database this will likely either just ** pass unnoticed, or result in SQLITE_CONSTRAINT errors (due to UNIQUE ** constraint violations). ** ** If some client does modify the target database mid OTA update, or some ** other error occurs, the OTA extension will keep throwing errors. It's ** not really clear how to get out of this state. The system could just ** by delete the OTA update database and *-oal file and have the device ** download the update again and start over. ** ** At present, for an UPDATE, both the new.* and old.* records are ** collected in the ota_xyz table. And for both UPDATEs and DELETEs all ** fields are collected. This means we're probably writing a lot more ** data to disk when saving the state of an ongoing update to the OTA ** update database than is strictly necessary. ** */ #include <assert.h> #include <string.h> #include <stdio.h> #include <unistd.h> #include "sqlite3.h" #if !defined(SQLITE_CORE) || defined(SQLITE_ENABLE_OTA) #include "sqlite3ota.h" /* Maximum number of prepared UPDATE statements held by this module */ #define SQLITE_OTA_UPDATE_CACHESIZE 16 /* ** Swap two objects of type TYPE. */ #if !defined(SQLITE_AMALGAMATION) # define SWAP(TYPE,A,B) {TYPE t=A; A=B; B=t;} #endif /* ** The ota_state table is used to save the state of a partially applied ** update so that it can be resumed later.

The VFS shim modifies the behaviour ** of a standard VFS in the following ways: ** ** 1. Whenever the first page of a main database file is read or ** written, the value of the change-counter cookie is stored in ** ota_file.iCookie. Similarly, the value of the "write-version" ** database header field is stored in ota_file.iWriteVer. This ensures ** that the values are always trustworthy within an open transaction. ** ** 2. Whenever an SQLITE_OPEN_WAL file is opened, the (ota_file.pWalFd) ** member variable of the associated database file descriptor is set ** to point to the new file. A mutex protected linked list of all main ** db fds opened using a particular OTA VFS is maintained at ** ota_vfs.pMain to facilitate this. ** ** 3. Using a new file-control "SQLITE_FCNTL_OTA", a main db ota_file ** object can be marked as the target database of an OTA update. This ** turns on the following extra special behaviour: ** ** 3a. If xAccess() is called to check if there exists a *-wal file ** associated with an OTA target database currently in OTA_STAGE_OAL ** stage (preparing the *-oal file), the following special handling ** applies: ** ** * if the *-wal file does exist, return SQLITE_CANTOPEN. An OTA ** target database may not be in wal mode already. ** ** * if the *-wal file does not exist, set the output parameter to ** non-zero (to tell SQLite that it does exist) anyway. ** ** Then, when xOpen() is called to open the *-wal file associated with ** the OTA target in OTA_STAGE_OAL stage, instead of opening the *-wal ** file, the ota vfs opens the corresponding *-oal file instead. ** ** 3b. The *-shm pages returned by xShmMap() for a target db file in ** OTA_STAGE_OAL mode are actually stored in heap memory. This is to ** avoid creating a *-shm file on disk. Additionally, xShmLock() calls ** are no-ops on target database files in OTA_STAGE_OAL mode. This is ** because assert() statements in some VFS implementations fail if ** xShmLock() is called before xShmMap(). ** ** 3c. If an EXCLUSIVE lock is attempted on a target database file in any ** mode except OTA_STAGE_DONE (all work completed and checkpointed), it ** fails with an SQLITE_BUSY error. This is to stop OTA connections ** from automatically checkpointing a *-wal (or *-oal) file from within ** sqlite3_close(). ** ** 3d. In OTA_STAGE_CAPTURE mode, all xRead() calls on the wal file, and ** all xWrite() calls on the target database file perform no IO. ** Instead the frame and page numbers that would be read and written ** are recorded. Additionally, successful attempts to obtain exclusive ** xShmLock() WRITER, CHECKPOINTER and READ0 locks on the target ** database file are recorded. xShmLock() calls to unlock the same ** locks are no-ops (so that once obtained, these locks are never ** relinquished).

If the ** working set of leaves is larger than the available cache memory, then a ** single leaf that is modified more than once as part of the transaction ** may be loaded from or written to the persistent media multiple times. ** Additionally, because the index updates are likely to be applied in ** random order, access to pages within the database is also likely to be in ** random order, which is itself quite inefficient. ** ** One way to improve the situation is to sort the operations on each index ** by index key before applying them to the b-tree. This leads to an IO ** pattern that resembles a single linear scan through the index b-tree, ** and all but guarantees each modified leaf page is loaded and stored ** exactly once. SQLite uses this trick to improve the performance of ** CREATE INDEX commands. This extension allows it to be used to improve ** the performance of large transactions on existing databases. ** ** Additionally, this extension allows the work involved in writing the ** large transaction to be broken down into sub-transactions performed ** sequentially by separate processes. This is useful if the system cannot ** guarantee that a single update process will run for long enough to apply ** the entire update, for example because the update is being applied on a ** mobile device that is frequently rebooted. Even after the writer process ** has committed one or more sub-transactions, other database clients continue ** to read from the original database snapshot. In other words, partially ** applied transactions are not visible to other clients. ** ** "OTA" stands for "Over The Air" update. As in a large database update ** transmitted via a wireless network to a mobile device. A transaction ** applied using this extension is hence refered to as an "OTA update". ** ** ** LIMITATIONS ** ** An "OTA update" transaction is subject to the following limitations: ** ** * The transaction must consist of INSERT, UPDATE and DELETE operations ** only. ** ** * INSERT statements may not use any default values. ** ** * UPDATE and DELETE statements must identify their target rows by ** non-NULL PRIMARY KEY values. Rows with NULL values stored in PRIMARY ** KEY fields may not be updated or deleted. If the table being written ** has no PRIMARY KEY, affected rows must be identified by rowid. ** ** * UPDATE statements may not modify PRIMARY KEY columns. ** ** * No triggers will be fired. ** ** * No foreign key violations are detected or reported. ** ** * CHECK constraints are not enforced. ** ** * No constraint handling mode except for "OR ROLLBACK" is supported. ** ** ** PREPARATION ** ** An "OTA update" is stored as a separate SQLite database. A database ** containing an OTA update is an "OTA database". For each table in the ** target database to be updated, the OTA database should contain a table ** named "data_<target name>" containing the same set of columns as the ** target table, and one more - "ota_control". The data_% table should ** have no PRIMARY KEY or UNIQUE constraints, but each column should have ** the same type as the corresponding column in the target database. ** The "ota_control" column should have no type at all. For example, if ** the target database contains: ** ** CREATE TABLE t1(a INTEGER PRIMARY KEY, b TEXT, c UNIQUE); ** ** Then the OTA database should contain: ** ** CREATE TABLE data_t1(a INTEGER, b TEXT, c, ota_control); ** ** The order of the columns in the data_% table does not matter. ** ** If the target database table is a virtual table or a table that has no ** PRIMARY KEY declaration, the data_% table must also contain a column ** named "ota_rowid". This column is mapped to the tables implicit primary ** key column - "rowid". Virtual tables for which the "rowid" column does ** not function like a primary key value cannot be updated using OTA. For ** example, if the target db contains either of the following: ** ** CREATE VIRTUAL TABLE x1 USING fts3(a, b); ** CREATE TABLE x1(a, b) ** ** then the OTA database should contain: ** ** CREATE TABLE data_x1(a, b, ota_rowid, ota_control); ** ** All non-hidden columns (i.e. all columns matched by "SELECT *") of the ** target table must be present in the input table. For virtual tables, ** hidden columns are optional - they are updated by OTA if present in ** the input table, or not otherwise. For example, to write to an fts4 ** table with a hidden languageid column such as: ** ** CREATE VIRTUAL TABLE ft1 USING fts4(a, b, languageid='langid'); ** ** Either of the following input table schemas may be used: ** ** CREATE TABLE data_ft1(a, b, langid, ota_rowid, ota_control); ** CREATE TABLE data_ft1(a, b, ota_rowid, ota_control); ** ** For each row to INSERT into the target database as part of the OTA ** update, the corresponding data_% table should contain a single record ** with the "ota_control" column set to contain integer value 0. The ** other columns should be set to the values that make up the new record ** to insert. ** ** If the target database table has an INTEGER PRIMARY KEY, it is not ** possible to insert a NULL value into the IPK column. Attempting to ** do so results in an SQLITE_MISMATCH error. ** ** For each row to DELETE from the target database as part of the OTA ** update, the corresponding data_% table should contain a single record ** with the "ota_control" column set to contain integer value 1. The ** real primary key values of the row to delete should be stored in the ** corresponding columns of the data_% table. The values stored in the ** other columns are not used. ** ** For each row to UPDATE from the target database as part of the OTA ** update, the corresponding data_% table should contain a single record ** with the "ota_control" column set to contain a value of type text. ** The real primary key values identifying the row to update should be ** stored in the corresponding columns of the data_% table row, as should ** the new values of all columns being update. The text value in the ** "ota_control" column must contain the same number of characters as ** there are columns in the target database table, and must consist entirely ** of 'x' and '.' characters (or in some special cases 'd' - see below). For ** each column that is being updated, the corresponding character is set to ** 'x'. For those that remain as they are, the corresponding character of the ** ota_control value should be set to '.'. For example, given the tables ** above, the update statement: ** ** UPDATE t1 SET c = 'usa' WHERE a = 4; ** ** is represented by the data_t1 row created by: ** ** INSERT INTO data_t1(a, b, c, ota_control) VALUES(4, NULL, 'usa', '..x'); ** ** Instead of an 'x' character, characters of the ota_control value specified ** for UPDATEs may also be set to 'd'. In this case, instead of updating the ** target table with the value stored in the corresponding data_% column, the ** user-defined SQL function "ota_delta()" is invoked and the result stored in ** the target table column. ota_delta() is invoked with two arguments - the ** original value currently stored in the target table column and the ** value specified in the data_xxx table. ** ** For example, this row: ** ** INSERT INTO data_t1(a, b, c, ota_control) VALUES(4, NULL, 'usa', '..d'); ** ** is similar to an UPDATE statement such as: ** ** UPDATE t1 SET c = ota_delta(c, 'usa') WHERE a = 4; ** ** If the target database table is a virtual table or a table with no PRIMARY ** KEY, the ota_control value should not include a character corresponding ** to the ota_rowid value. For example, this: ** ** INSERT INTO data_ft1(a, b, ota_rowid, ota_control) ** VALUES(NULL, 'usa', 12, '.x'); ** ** causes a result similar to: ** ** UPDATE ft1 SET b = 'usa' WHERE rowid = 12; ** ** The data_xxx tables themselves should have no PRIMARY KEY declarations. ** However, OTA is more efficient if reading the rows in from each data_xxx ** table in "rowid" order is roughly the same as reading them sorted by ** the PRIMARY KEY of the corresponding target database table. In other ** words, rows should be sorted using the destination table PRIMARY KEY ** fields before they are inserted into the data_xxx tables. ** ** USAGE ** ** The API declared below allows an application to apply an OTA update ** stored on disk to an existing target database. Essentially, the ** application: ** ** 1) Opens an OTA handle using the sqlite3ota_open() function. ** ** 2) Registers any required virtual table modules with the database ** handle returned by sqlite3ota_db(). Also, if required, register ** the ota_delta() implementation. ** ** 3) Calls the sqlite3ota_step() function one or more times on ** the new handle. Each call to sqlite3ota_step() performs a single ** b-tree operation, so thousands of calls may be required to apply ** a complete update. ** ** 4) Calls sqlite3ota_close() to close the OTA update handle. If ** sqlite3ota_step() has been called enough times to completely ** apply the update to the target database, then the OTA database ** is marked as fully applied. Otherwise, the state of the OTA ** update application is saved in the OTA database for later ** resumption. ** ** See comments below for more detail on APIs. ** ** If an update is only partially applied to the target database by the ** time sqlite3ota_close() is called, various state information is saved ** within the OTA database. This allows subsequent processes to automatically ** resume the OTA update from where it left off. ** ** To remove all OTA extension state information, returning an OTA database ** to its original contents, it is sufficient to drop all tables that begin ** with the prefix "ota_" ** ** DATABASE LOCKING ** ** An OTA update may not be applied to a database in WAL mode. Attempting ** to do so is an error (SQLITE_ERROR). ** ** While an OTA handle is open, a SHARED lock may be held on the target ** database file. This means it is possible for other clients to read the ** database, but not to write it. ** ** If an OTA update is started and then suspended before it is completed, ** then an external client writes to the database, then attempting to resume ** the suspended OTA update is also an error (SQLITE_BUSY). */ #ifndef _SQLITE3OTA_H #define _SQLITE3OTA_H #include "sqlite3.h" /* Required for error code definitions */ typedef struct sqlite3ota sqlite3ota; /* ** Open an OTA handle. ** ** Argument zTarget is the path to the target database.
