In IntelliJ, using `$MODULE_DIR$` accomplishes this automatically. + +Additionally, the Hive plugin must be configured with location of your Hive metastore Thrift service. Add the following to the list of VM options, replacing `localhost:9083` with the correct host and port (or use the below value if you do not have a Hive metastore): + + -Dhive.metastore.uri=thrift://localhost:9083 + +### Using SOCKS for Hive or HDFS + +If your Hive metastore or HDFS cluster is not directly accessible to your local machine, you can use SSH port forwarding to access it. Setup a dynamic SOCKS proxy with SSH listening on local port 1080: + + ssh -v -N -D 1080 server + +Then add the following to the list of VM options: + + -Dhive.metastore.thrift.client.socks-proxy=localhost:1080 + +### Running the CLI + +Start the CLI to connect to the server and run SQL queries: + + presto-cli/target/presto-cli-*-executable.jar + +Run a query to see the nodes in the cluster: + + SELECT * FROM system.runtime.nodes; + +In the sample configuration, the Hive connector is mounted in the `hive` catalog, so you can run the following queries to show the tables in the Hive database `default`: + + SHOW TABLES FROM hive.default; diff --git a/pom.xml b/pom.xml new file mode 100644 index 00000000..3a0951ec --- /dev/null +++ b/pom.xml

If no +table definition file exists for a table, the ``dummy`` decoder is used. + +The Kafka connector contains the following decoders: + +* ``raw`` - do not convert the row data, use as raw bytes +* ``csv`` - interpret the value as CSV +* ``json`` - convert the value to a JSON object + +The main purpose of the decoders is to select the appropriate field +decoders to interpret the message or key data. + +Presto supports only four physical data types onto which the Presto types +are mapped: boolean, long, double and a sequence of bytes which is treated +as a string. + +``raw`` Decoder +^^^^^^^^^^^^^^^ + +The raw decoder supports reading of raw (byte based) values from a message +or key and converting it into Presto columns. + +For fields, the following attributes are supported: + +* ``type`` - All Presto data types are supported +* ``dataFormat`` - Only ``_default`` supported, can be omitted. +* ``mapping`` - selects the width of the data type converted +* ``formatHint`` - optional, ``[:]``; start and end position of bytes to convert + +The ``mapping`` column selects the number of bytes converted. +If absent, ``BYTE`` is assumed. All values are signed. + +Supported values are: + +* ``BYTE`` - one byte +* ``SHORT`` - two bytes +* ``INT`` - four bytes +* ``LONG`` - eight bytes +* ``FLOAT`` - four bytes (IEEE 754 format) +* ``DOUBLE`` - eight bytes (IEEE 754 format) + +The ``type`` column defines the Presto data type on which the value is mapped. + +* boolean based types require a mapping to ``BYTE``, ``SHORT``, ``INT`` or ``LONG``. + Any other type will throw a conversion error. + A value of ``0`` returns false, everything else true. +* long based types require a mapping to ``BYTE``, ``SHORT``, ``INT`` or ``LONG``. + Any other type will throw a conversion error. +* double based types require a mapping to ``FLOAT`` or ``DOUBLE``. + Any other type will throw a conversion error. +* string based types require a mapping to ``BYTE``. + Any other type will throw a conversion error. + +The ``formatHint`` field specifies the position of the bytes in a key or +message. It can be one or two numbers separated by a colon (``[:]``). +If only a start position is given, the column will use the appropriate +number of bytes for the type (see above). string based types (``VARCHAR``) +will use all bytes to the end of the message. If start and end position is +given, then for fixed with types the size must be at least the size of the +type. For string based types, all bytes between start (inclusive) and end +(exclusive) are used. + +``csv`` Decoder +^^^^^^^^^^^^^^^ + +.. note:: The CSV decoder is of beta quality and should be used with caution. + +The CSV decoder converts the bytes representing a message or key into a +string using UTF-8 encoding and then interprets the result as a CSV +(comma-separated value) line. + +For fields, the following attributes are supported: + +* ``type`` - All Presto data types are supported +* ``dataFormat`` - Only ``_default`` supported, can be omitted +* ``mapping`` - field index used for the column. Must be given +* ``formatHint`` - not supported, ignored + +* boolean based types return ``true`` if the field value is the string "true" (case insensitive), ``false`` otherwise. +* long and double based types parse the field value according to Java long and double parse rules. +* string types use the field as-is (text using UTF-8 encoding) + +``json`` Decoder +^^^^^^^^^^^^^^^^ + +The JSON decoder converts the bytes representing a message or key into a +JSON according to :rfc:`4627`. Note that the message or key *MUST* convert +into a JSON object, not an array or simple type. + +For fields, the following attributes are supported: + +* ``type`` - All Presto data types are supported +* ``dataFormat`` - ``_default``, ``custom-date-time``, ``iso8601``, ``rfc2822``, + ``milliseconds-since-epoch``, ``seconds-since-epoch``. If missing, ``_default`` is used. +* ``mapping`` - slash-separated list of fields names to select a field from the JSON object. +* ``formatHint`` - only for ``custom-date-time``, see below. + +The JSON decoder supports multiple field decoders, with ``_default`` being +used for standard table columns and a number of decoders for date and time +based types. + +``_default`` Field decoder +^^^^^^^^^^^^^^^^^^^^^^^^^^ + +This is the standard field decoder supporting all the Presto physical data +types. A field value will be coerced by JSON conversion rules into +boolean, long, double or string values.

A window has three components: + +* The partition specification, which separates the input rows into different + partitions. This is analogous to how the ``GROUP BY`` clause separates rows + into different groups for aggregate functions. +* The ordering specification, which determines the order in which input rows + will be processed by the window function. +* The window frame, which specifies a sliding window of rows to be processed + by the function for a given row. If the frame is not specified, it defaults + to ``RANGE UNBOUNDED PRECEDING``, which is the same as + ``RANGE BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW``. This frame contains all + rows from the start of the partition up to the last peer of the current row. + +For example, the following query ranks orders for each clerk by price:: + + SELECT orderkey, clerk, totalprice, + rank() OVER (PARTITION BY clerk + ORDER BY totalprice DESC) AS rnk + FROM orders + ORDER BY clerk, rnk + +Aggregate Functions +------------------- + +All :doc:`aggregate` can be used as window functions by adding the ``OVER`` +clause. The aggregate function is computed for each row over the rows within +the current row's window frame. + +For example, the following query produces a rolling sum of order prices +by day for each clerk:: + + SELECT clerk, orderdate, orderkey, totalprice, + sum(totalprice) OVER (PARTITION BY clerk + ORDER BY orderdate) AS rolling_sum + FROM orders + ORDER BY clerk, orderdate, orderkey + +Ranking Functions +----------------- + +.. function:: cume_dist() -> bigint + + Returns the cumulative distribution of a value in a group of values. + The result is the number of rows preceding or peer with the row in the + window ordering of the window partition divided by the total number of + rows in the window partition. Thus, any tie values in the ordering will + evaluate to the same distribution value. + +.. function:: dense_rank() -> bigint + + Returns the rank of a value in a group of values. This is similar to + :func:`rank`, except that tie values do not produce gaps in the sequence. + +.. function:: ntile(n) -> bigint + + Divides the rows for each window partition into ``n`` buckets ranging + from ``1`` to at most ``n``. Bucket values will differ by at most ``1``. + If the number of rows in the partition does not divide evenly into the + number of buckets, then the remainder values are distributed one per + bucket, starting with the first bucket. + + For example, with ``6`` rows and ``4`` buckets, the bucket values would + be as follows: ``1`` ``1`` ``2`` ``2`` ``3`` ``4`` + +.. function:: percent_rank() -> bigint + + Returns the percentage ranking of a value in group of values. The result + is ``(r - 1) / (n - 1)`` where ``r`` is the :func:`rank` of the row and + ``n`` is the total number of rows in the window partition. + +.. function:: rank() -> bigint + + Returns the rank of a value in a group of values. The rank is one plus + the number of rows preceding the row that are not peer with the row. + Thus, tie values in the ordering will produce gaps in the sequence. + The ranking is performed for each window partition. + +.. function:: row_number() -> bigint + + Returns a unique, sequential number for each row, starting with one, + according to the ordering of rows within the window partition. + +Value Functions +--------------- + +.. function:: first_value(x) -> [same as input] + + Returns the first value of the window. + +.. function:: last_value(x) -> [same as input] + + Returns the last value of the window. + +.. function:: nth_value(x, offset) -> [same as input] + + Returns the value at the specified offset from beginning the window. + Offsets start at ``1``. The offset can be any scalar + expression. If the offset is null or greater than the number of values in + the window, null is returned. It is an error for the offset to be zero or + negative. + +.. function:: lead(x[, offset [, default_value]]) -> [same as input] + + Returns the value at ``offset`` rows after the current row in the window. + Offsets start at ``0``, which is the current row. The + offset can be any scalar expression. The default ``offset`` is ``1``. If the + offset is null or larger than the window, the ``default_value`` is returned, + or if it is not specified ``null`` is returned. + +.. function:: lag(x[, offset [, default_value]]) -> [same as input] + + Returns the value at ``offset`` rows before the current row in the window + Offsets start at ``0``, which is the current row.

All Presto nodes in a cluster must + have the same environment name. + +* ``node.id``: + The unique identifier for this installation of Presto. This must be + unique for every node. This identifier should remain consistent across + reboots or upgrades of Presto. If running multiple installations of + Presto on a single machine (i.e. multiple nodes on the same machine), + each installation must have a unique identifier. + +* ``node.data-dir``: + The location (filesystem path) of the data directory. Presto will store + logs and other data here. + +.. _presto_jvm_config: + +JVM Config +^^^^^^^^^^ + +The JVM config file, ``etc/jvm.config``, contains a list of command line +options used for launching the Java Virtual Machine. The format of the file +is a list of options, one per line. These options are not interpreted by +the shell, so options containing spaces or other special characters should +not be quoted (as demonstrated by the ``OnOutOfMemoryError`` option in the +example below). + +The following provides a good starting point for creating ``etc/jvm.config``: + +.. code-block:: none + + -server + -Xmx16G + -XX:+UseConcMarkSweepGC + -XX:+ExplicitGCInvokesConcurrent + -XX:+AggressiveOpts + -XX:+HeapDumpOnOutOfMemoryError + -XX:OnOutOfMemoryError=kill -9 %p + +Because an ``OutOfMemoryError`` will typically leave the JVM in an +inconsistent state, we write a heap dump (for debugging) and forcibly +terminate the process when this occurs. + + +.. _config_properties: + +Config Properties +^^^^^^^^^^^^^^^^^ + +The config properties file, ``etc/config.properties``, contains the +configuration for the Presto server. Every Presto server can function +as both a coordinator and a worker, but dedicating a single machine +to only perform coordination work provides the best performance on +larger clusters. + +The following is a minimal configuration for the coordinator: + +.. code-block:: none + + coordinator=true + node-scheduler.include-coordinator=false + http-server.http.port=8080 + task.max-memory=1GB + discovery-server.enabled=true + discovery.uri=http://example.net:8080 + +And this is a minimal configuration for the workers: + +.. code-block:: none + + coordinator=false + http-server.http.port=8080 + task.max-memory=1GB + discovery.uri=http://example.net:8080 + +Alternatively, if you are setting up a single machine for testing that +will function as both a coordinator and worker, use this configuration: + +.. code-block:: none + + coordinator=true + node-scheduler.include-coordinator=true + http-server.http.port=8080 + task.max-memory=1GB + discovery-server.enabled=true + discovery.uri=http://example.net:8080 + +These properties require some explanation: + +* ``coordinator``: + Allow this Presto instance to function as a coordinator + (accept queries from clients and manage query execution). + +* ``node-scheduler.include-coordinator``: + Allow scheduling work on the coordinator. + For larger clusters, processing work on the coordinator + can impact query performance because the machine's resources are not + available for the critical task of scheduling, managing and monitoring + query execution. + +* ``http-server.http.port``: + Specifies the port for the HTTP server. Presto uses HTTP for all + communication, internal and external. + +* ``task.max-memory=1GB``: + The maximum amount of memory used by a single task + (a fragment of a query plan running on a specific node). + In particular, this limits the number of groups in a ``GROUP BY``, + the size of the right-hand table in a ``JOIN``, the number of rows + in an ``ORDER BY`` or the number of rows processed by a window function. + This value should be tuned based on the number of concurrent queries and + the size and complexity of queries. Setting it too low will limit the + queries that can be run, while setting it too high will cause the JVM + to run out of memory. + +* ``discovery-server.enabled``: + Presto uses the Discovery service to find all the nodes in the cluster. + Every Presto instance will register itself with the Discovery service + on startup. In order to simplify deployment and avoid running an additional + service, the Presto coordinator can run an embedded version of the + Discovery service. It shares the HTTP server with Presto and thus uses + the same port. + +* ``discovery.uri``: + The URI to the Discovery server. Because we have enabled the embedded + version of Discovery in the Presto coordinator, this should be the + URI of the Presto coordinator. Replace ``example.net:8080`` to match + the host and port of the Presto coordinator. This URI must not end + in a slash. + +* ``query.queue-config-file``: + Specifies the file to read the :doc:`/admin/queue` from. + +Log Levels +^^^^^^^^^^ + +The optional log levels file, ``etc/log.properties``, allows setting the +minimum log level for named logger hierarchies. Every logger has a name, +which is typically the fully qualified name of the class that uses the logger. +Loggers have a hierarchy based on the dots in the name (like Java packages). +For example, consider the following log levels file: + +.. code-block:: none + + com.facebook.presto=INFO + +This would set the minimum level to ``INFO`` for both +``com.facebook.presto.server`` and ``com.facebook.presto.hive``. +The default minimum level is ``INFO`` +(thus the above example does not actually change anything). +There are four levels: ``DEBUG``, ``INFO``, ``WARN`` and ``ERROR``. + +Catalog Properties +^^^^^^^^^^^^^^^^^^ + +Presto accesses data via *connectors*, which are mounted in catalogs. +The connector provides all of the schemas and tables inside of the catalog. +For example, the Hive connector maps each Hive database to a schema, +so if the Hive connector is mounted as the ``hive`` catalog, and Hive +contains a table ``clicks`` in database ``web``, that table would be accessed +in Presto as ``hive.web.clicks``. + +Catalogs are registered by creating a catalog properties file +in the ``etc/catalog`` directory. +For example, create ``etc/catalog/jmx.properties`` with the following +contents to mount the ``jmx`` connector as the ``jmx`` catalog: + +.. code-block:: none + + connector.name=jmx + +See :doc:`/connector` for more information about configuring connectors. + +.. _running_presto: + +Running Presto +-------------- + +The installation directory contains the launcher script in ``bin/launcher``. +Presto can be started as a daemon by running running the following: + +.. code-block:: none + + bin/launcher start + +Alternatively, it can be run in the foreground, with the logs and other +output being written to stdout/stderr (both streams should be captured +if using a supervision system like daemontools): + +.. code-block:: none + + bin/launcher run + +Run the launcher with ``--help`` to see the supported commands and +command line options. In particular, the ``--verbose`` option is +very useful for debugging the installation. + +After launching, you can find the log files in ``var/log``: + +* ``launcher.log``: + This log is created by the launcher and is connected to the stdout + and stderr streams of the server. It will contain a few log messages + that occur while the server logging is being initialized and any + errors or diagnostics produced by the JVM. + +* ``server.log``: + This is the main log file used by Presto. It will typically contain + the relevant information if the server fails during initialization. + It is automatically rotated and compressed. + +* ``http-request.log``: + This is the HTTP request log which contains every HTTP request + received by the server. It is automatically rotated and compressed. diff --git a/presto-docs/src/main/sphinx/installation/jdbc.rst b/presto-docs/src/main/sphinx/installation/jdbc.rst new file mode 100644 index 00000000..2e95a564 --- /dev/null +++ b/presto-docs/src/main/sphinx/installation/jdbc.rst @@ -0,0 +1,21 @@ +=========== +JDBC Driver +=========== + +Presto can be accessed from Java using the JDBC driver. +Download :download:`jdbc` and add it to the class path of your Java application. +The following JDBC URL formats are supported: + +.. code-block:: none + + jdbc:presto://host:port + jdbc:presto://host:port/catalog + jdbc:presto://host:port/catalog/schema + +For example, use the following URL to connect to Presto +running on ``example.net`` port ``8080`` with the catalog ``hive`` +and the schema ``sales``: + +.. code-block:: none + + jdbc:presto://example.net:8080/hive/sales diff --git a/presto-docs/src/main/sphinx/installation/verifier.rst b/presto-docs/src/main/sphinx/installation/verifier.rst new file mode 100644 index 00000000..43b4ba65 --- /dev/null +++ b/presto-docs/src/main/sphinx/installation/verifier.rst @@ -0,0 +1,45 @@ +=============== +Presto Verifier +=============== + +The Presto Verifier can be used to test Presto against another database (such as MySQL), +or to test two Presto clusters against each other.

As a +Presto administrator or a Presto contributor you should understand how +Presto's concepts of stages map to tasks and how tasks contain a set +of drivers which process data. + +This section provides a solid definition for the core concepts +referenced throughout Presto, and these sections are sorted from most +general to most specific. + +-------------- +Presto Servers +-------------- + +There are two types of Presto servers: coordinators and workers. The +following section explains the difference between the two. + +^^^^^^^^^^^ +Coordinator +^^^^^^^^^^^ + +The Presto coordinator is a server that is responsible for parsing +statements, planning queries, and managing Presto worker nodes. It is +the "brains" of a Presto installation and is also the node to which a +client connects to submit statements for execution. + +Every Presto installation must have at least one Presto coordinator +alongside zero or more Presto workers. The coordinator keeps track of +the activity on each worker and coordinates the delivery of data to +the components created to execute a query. Coordinators keep track of +a logical model of a query involving a series of stages which is then +translated into a series of connected tasks running on a cluster of +Presto workers. + +Coordinators communicate with both workers and clients using a REST +API. + +^^^^^^ +Worker +^^^^^^ + +A Presto worker is a server in a Presto installation which is +responsible for executing tasks and processing data. Worker nodes +consume data and produce results for either other workers involved in +the same query or a coordinator acting as a go-between for a Presto +client. + +When a Presto worker becomes available, it advertises itself using a +discovery server making itself available to a Presto coordinator for +task execution. + +Workers communicate with both other workers and Presto coordinators +using a REST API. + +--------------------------- +Presto Data Source Concepts +--------------------------- + +Throughout this documentation you'll read terms such as connector, +catalog, schema, and table. These fundamental concepts cover Presto's +model of a particular data source and are described in the following +section. + +^^^^^^^^^ +Connector +^^^^^^^^^ + +A connector adapts Presto to a data source such as Hive or a +relational database. You can think of a connector the same way you +think of a driver for a database. It is an implementation of Presto's +SPI which allows Presto to interact with a resource using a standard +API. + +Presto contains several built-in connectors including a connector for +JMX, a "system" connector which provides access to built-in system +tables, a Hive connector, and a connector designed to serve TPC-H benchmark +data. Many third-party developers have contributed connectors so that +Presto can access data in a variety of data sources. + +Every catalog is associated with a specific connector. If you examine +a catalog configuration file, you will see that each contains a +mandatory property "connector.name" which is used by the Catalog +manager to create a connector for a given catalog. It is possible +to have more than one catalog use the same connector to access two +different instances of a similar database. For example, if you have +two Hive clusters, you can configure two catalogs which use the Hive +connector to query data from either database. + +^^^^^^^ +Catalog +^^^^^^^ + +A Presto catalog contains schemas and references a data source via a +connector. For example, the JMX catalog is a built-in catalog in +Presto which provides access to JMX information via a JMX connector. +When you run a SQL statement in Presto, you are running it against a +catalog. Other examples of catalogs include the Hive catalog to +connect to a Hive data source. + +When addressing a table in Presto, the fully-qualified table name is +always rooted in a catalog. For example, a fully-qualified table name +of "hive.test_data.test" would refer to the test table in the +test_data schema in the hive catalog. + +Catalogs are defined in properties files stored in the Presto +configuration directory. + +^^^^^^ +Schema +^^^^^^ + +A schema is grouping of tables. Think of a traditional relational +database such as Postgresql, MySQL, or Oracle. Each one of those +database products has the concept of a schema and a Presto schema maps +to the same concept. Tables are grouped into schemas to organize +tables into schemas which share a common purpose. + +A Catalog and Schema together define a set of tables that can be +queried. When accessing Hive or a relational database with Presto, a +schema refers to the same concept in the target database. When +accessing a catalog such as JMX, schema simply refers to a set of +tables used to represent JMX information and does not directly +correspond to a similar concept in the underlying technology. + +^^^^^ +Table +^^^^^ + +Presto's concept of a table isn't too different from a table in a +relational database. A table contains rows which have data in a +series of named columns. + +------------------ +Presto Query Model +------------------ + +Presto executes SQL statements and turns these statements into queries +that are executed across a distributed network of coordinators and +workers. + +^^^^^^^^^ +Statement +^^^^^^^^^ + +Presto executes ANSI-compatible SQL statements. When Presto +documentation refers to a statement we are refering to statements as +defined in the ANSI SQL standard which consists of clauses, +expressions, and predicates. + +Some readers might be curious why this section lists seperate concepts +for statements and queries. This is necessary because, in Presto, +statements simply refer to the textual representation of a SQL +statement. When a statement is executed, Presto creates a query along +with a query plan that is then distributed across a series of Presto +workers. + +^^^^^ +Query +^^^^^ + +When Presto parses a statement it converts it into a query and creates +a distributed query plan which is then realized as a series of +interconnected stages running on Presto Workers. When you retrieve +information about a query in Presto, you receive a snapshot of every +component that is involved in producing a result set in response to a +statement. + +The difference between a statement and a query is simple. A statement +can be thought of as the string that is passed to Presto while a query +refers to the configuration and components instantiated to execute +that statement. A query encompasses stages, tasks, splits, catalogs, +and other components and data sources working in concert to produce a +result. + +^^^^^ +Stage +^^^^^ + +When Presto executes a query it does so by breaking up the execution +into a hierarchy of stages. For example, if Presto needs to aggregate +data from one billion rows stored in Hive it does so by creating a +root stage to aggregate the output of several other stages all of +which are designed to implement different sections of a distributed +query plan. + +The hierarchy of stages that comprises a query resembles a tree. +Every query has a "root" stage which is responsible for aggregating +the output from other stages. Stages are what the coordinator uses to +model a distributed query plan, but stages themselves don't run on +Presto workers. + +Note: If you are a Presto end-user, everything beyond Stage in this +section isn't necessary to understand how Presto works from an +end-user perspective. + +^^^^^^^^ +Exchange +^^^^^^^^ + +Stages connect to one another using an exchange. An exchange is +responsible for receiving and transporting data from one stage to +another and for interacting with other stages to retrieve data. A +stage that produces data has an exchange called an output buffer, and +a stage that consumes data has an exchange called an exchange client. + +Note that data is retrieved from the lowest level stage directly +from a connector. This interaction between a stage and a connector +uses an operator called a source operator. For example, if a stage +retrieves data from HDFS, this isn't performed with an exchange +client, the retrieval happens from a source operator running in a +driver. + +^^^^ +Task +^^^^ + +As mentioned in the previous section, stages model a particular +section of a distributed query plan, but stages themselves don't +execute on Presto workers. To understand how a stage is executed, +you'll need to understand that a stage is implemented as a series of +tasks distributed over a network of Presto workers. + +Tasks are the "work horse" in the Presto architecture as a distributed +query plan is deconstructed into a series of stages which are then +translated to tasks which then act upon or process splits. A Presto +task has inputs and outputs, and just as a stage can be executed in +parallel by a series of tasks, a task is executing in parallel with a +series of drivers. + +^^^^^^ +Driver +^^^^^^ + +Tasks contain one or more parallel drivers. Drivers act upon data and +combine operators to produce output that is then aggregated by a task +and then delivered to another task in a another stage. A driver is a +sequence of operator instances, or you can think of a driver as a +physical set of operators in memory. It is the lowest level of +parallelism in the Presto architecture. A driver has one input and +one output. + +^^^^^^^^ +Operator +^^^^^^^^ + +An Operator in Presto encapsulates the functionality of functions and +other operations which take data as input and generate data as output. +Operators execute within a driver as a driver is simply an +assembly of different operators which are then applied to individual +pieces of data within a split. + +^^^^^ +Split +^^^^^ + +Tasks operate on splits, and splits are sections of larger data +set. Stages at the lowest level of a distributed query plan retrieve splits +from connectors, and intermediate stages at a higher level of a +distributed query plan are designed to retrieve data from other +stages. + +When Presto is scheduling a query, the coordinator will query a +connector for a list of all splits that are available for a table. +The coordinator keeps track of which machines are running which tasks +and what splits are being processed by which tasks. + + +..

In this release we have added a fast path for for RCFile when using +the Binary SerDe (``LazyBinaryColumnarSerDe``). In our +micro benchmarks, we see a gain between 2x and 4x in CPU efficiency compared +to the generic (slow) path. Since Hive data decoding accounts for a +significant portion of the CPU time, this should +result in measurable gains for most queries over RC Binary encoded data. +Note that this optimization may not result in a reduction in latency +if your cluster is network or disk I/O bound. + +Hash Distributed Aggregations +----------------------------- + +``GROUP BY`` aggregations are now distributed across a fixed number of machines. +This is controlled by the property ``query.initial-hash-partitions`` set in +``etc/config.properties`` of the coordinator and workers. If the value is +larger than the number of machines available during query scheduling, Presto +will use all available machines. The default value is ``8``. + +The maximum memory size of an aggregation is now +``query.initial-hash-partitions`` times ``task.max-memory``. + +Simple Distinct Aggregations +---------------------------- + +We have added support for the ``DISTINCT`` argument qualifier for aggregation +functions. This is currently limited to queries without a ``GROUP BY`` clause and +where all the aggregation functions have the same input expression. For example:: + + SELECT count(DISTINCT country) + FROM users + +Support for complete ``DISTINCT`` functionality is in our roadmap. + +Range Predicate Pushdown +------------------------ + +We've modified the connector API to support range predicates in addition to simple equality predicates. +This lays the ground work for adding connectors to systems that support range +scans (e.g., HBase, Cassandra, JDBC, etc). + +In addition to receiving range predicates, the connector can also communicate +back the ranges of each partition for use in the query optimizer. This can be a +major performance gain for ``JOIN`` queries where one side of the join has +only a few partitions. For example:: + + SELECT * FROM data_1_year JOIN data_1_week USING (ds) + +If ``data_1_year`` and ``data_1_week`` are both partitioned on ``ds``, the +connector will report back that one table has partitions for 365 days and the +other table has partitions for only 7 days. Then the optimizer will limit +the scan of the ``data_1_year`` table to only the 7 days that could possible +match. These constraints are combined with other predicates in the +query to further limit the data scanned. + +.. note:: + This is a backwards incompatible change with the previous connector SPI, + so if you have written a connector, you will need to update your code + before deploying this release. + +json_array_get Function +----------------------- + +The :func:`json_array_get` function makes it simple to fetch a single element from a +scalar json array. + +Non-reserved Keywords +--------------------- + +The keywords ``DATE``, ``TIME``, ``TIMESTAMP``, and ``INTERVAL`` are no longer +reserved keywords in the grammar. This means that you can access a column +named ``date`` without quoting the identifier. + +CLI source Option +----------------- + +The Presto CLI now has an option to set the query source. The source +value is shown in the UI and is recorded in events. When using the CLI in +shell scripts it is useful to set the ``--source`` option to distinguish shell +scripts from normal users. + +SHOW SCHEMAS FROM +----------------- + +Although the documentation included the syntax ``SHOW SCHEMAS [FROM catalog]``, +it was not implemented. This release now implements this statement correctly. + +Hive Bucketed Table Fixes +------------------------- + +For queries over Hive bucketed tables, Presto will attempt to limit scans to +the buckets that could possible contain rows that match the WHERE clause. +Unfortunately, the algorithm we were using to select the buckets was not +correct, and sometimes we would either select the wrong files or fail to +select any files. We have aligned +the algorithm with Hive and now the optimization works as expected. + +We have also improved the algorithm for detecting tables that are not properly +bucketed. It is common for tables to declare bucketing in the Hive metadata, but +not actually be bucketed in HDFS. When Presto detects this case, it fallback to a full scan of the +partition. Not only does this change make bucketing safer, but it makes it easier +to migrate a table to use bucketing without rewriting all of the data. diff --git a/presto-docs/src/main/sphinx/release/release-0.56.rst b/presto-docs/src/main/sphinx/release/release-0.56.rst new file mode 100644 index 00000000..6c4e5f3f --- /dev/null +++ b/presto-docs/src/main/sphinx/release/release-0.56.rst @@ -0,0 +1,36 @@ +============ +Release 0.56 +============ + +Table Creation +-------------- + +Tables can be created from the result of a query:: + + CREATE TABLE orders_by_date AS + SELECT orderdate, sum(totalprice) AS price + FROM orders + GROUP BY orderdate + +Tables are created in Hive without partitions (unpartitioned) and use +RCFile with the Binary SerDe (``LazyBinaryColumnarSerDe``) as this is +currently the best format for Presto. + +.. note:: + This is a backwards incompatible change to ``ConnectorMetadata`` in the SPI, + so if you have written a connector, you will need to update your code before + deploying this release.

Previously, this was handled by a generic +``getService`` method. + +.. note:: + This is a backwards incompatible change to ``Connector`` in the SPI, + so if you have written a connector, you will need to update your code before + deploying this release. + +Additionally, we have added the ``NodeManager`` interface to the SPI to allow a +plugin to detect all nodes in the Presto cluster. This is important for some +connectors that can divide a table evenly between all nodes as long as the +connector knows how many nodes exist. To access the node manager, simply add +the following to the ``Plugin`` class: + +.. code-block:: java + + @Inject + public void setNodeManager(NodeManager nodeManager) + { + this.nodeManager = nodeManager; + } + +Optimizations +------------- + +DISTINCT LIMIT +~~~~~~~~~~~~~~ + +For queries with the following form:: + + SELECT DISTINCT ... + FROM T + LIMIT N + +We have added an optimization that stops the query as soon as ``N`` distinct +rows are found. + +Range predicates +~~~~~~~~~~~~~~~~ + +When optimizing a join, Presto analyzes the ranges of the partitions on each +side of a join and pushes these ranges to the other side. When tables have a +lot of partitions, this can result in a very large filter with one expression +for each partition. The optimizer now summarizes the predicate ranges to reduce +the complexity of the filters. + +Compound filters +~~~~~~~~~~~~~~~~ + +Complex expressions involving ``AND``, ``OR``, or ``NOT`` are now optimized by +the expression optimizer. + +Window functions +~~~~~~~~~~~~~~~~ + +Window functions with a ``PARTITION BY`` clause are now distributed based on the +partition key. + +Bug fixes +--------- + +* Scheduling + + In the changes to schedule splits in batches, we introduced two bugs that + resulted in an unbalanced workload across nodes which increases query latency. + The first problem was not inspecting the queued split count of the nodes while + scheduling the batch, and the second problem was not counting the splits + awaiting creation in the task executor. + +* JSON conversion of complex Hive types + + Presto converts complex Hive types (array, map, struct and union) into JSON. + Previously, numeric keys in maps were converted to numbers, not strings, + which is invalid as JSON only allows strings for object keys. This prevented + the :doc:`/functions/json` from working. + +* Hive hidden files + + Presto will now ignore files in Hive that start with an underscore ``_`` or + a dot ``.``. This matches the behavior of Hadoop MapReduce / Hive. + +* Failures incorrectly reported as no data + + Certain types of failures would result in the query appearing to succeed and + return an incomplete result (often zero rows). There was a race condition + between the error propagation and query teardown. In some cases, the query + would be torn down before the exception made it to the coordinator. This was a + regression introduced during the query teardown optimization work. There are + now tests to catch this type of bug. + +* Exchange client leak + + When a query finished early (e.g., limit or failure) and the exchange operator + was blocked waiting for data from other nodes, the exchange was not be closed + properly. This resulted in continuous failing HTTP requests which leaked + resources and produced large log files. + +* Hash partitioning + + A query with many ``GROUP BY`` items could fail due to an overflow in the hash + function. + +* Compiled NULL literal + + In some cases queries with a select expression like ``CAST(NULL AS varchar)`` + would fail due to a bug in the output type detection code in expression + compiler. diff --git a/presto-docs/src/main/sphinx/release/release-0.61.rst b/presto-docs/src/main/sphinx/release/release-0.61.rst new file mode 100644 index 00000000..403abcca --- /dev/null +++ b/presto-docs/src/main/sphinx/release/release-0.61.rst @@ -0,0 +1,111 @@ +============ +Release 0.61 +============ + +Add support for Table Value Constructors +---------------------------------------- + +Presto now supports the SQL table value constructor syntax to create inline tables. +The ``VALUES`` clause can be used anywhere a ``SELECT`` statement is allowed. +For example, as a top-level query:: + + VALUES ('a', 1), ('b', 2); + +.. code-block:: none + + _col0 | _col1 + -------+------- + a | 1 + b | 2 + (2 rows) + +Alternatively, in the ``FROM`` clause:: + + SELECT * + FROM ( + VALUES + ('a', 'ape'), + ('b', 'bear') + ) AS animal (letter, animal) + JOIN ( + VALUES + ('a', 'apple'), + ('b', 'banana') + ) AS fruit (letter, fruit) + USING (letter); + +.. code-block:: none + + letter | animal | letter | fruit + --------+--------+--------+--------- + a | ape | a | apple + b | bear | b | banana + (2 rows) + + +Cassandra +--------- + +* Add support for upper-case schema, table, and columns names. + +* Add support for ``DECIMAL`` type. + +Amazon S3 support +----------------- + +* Completely rewritten Hadoop FileSystem implementation for S3 using the Amazon AWS SDK, + with major performance and reliability improvements. + +* Add support for writing data to S3. + +Approximate Aggregation Queries +------------------------------- + +We have added experimental support for aggregate queries that return +approximate results with error bounds.

For example, the new date/time +types include an operator for adding an ``INTERVAL`` to a ``TIMESTAMP``. + +Existing functions have been updated to operate on and return the +newly added types. For example, the ANSI color functions now operate +on a ``COLOR`` type, and the date/time functions operate on standard +SQL date/time types (described below). + +Finally, plugins can now provide custom types and operators in addition +to connectors and functions. This feature is highly experimental, so expect +the interfaces to change over the next few releases. Also, since in SQL +there is only one namespace for types, you should be careful to make names +for custom types unique as we will add other common SQL types to Presto +in the near future. + +Date/Time Types +--------------- + +Presto now supports all standard SQL date/time types: +``DATE``, ``TIME``, ``TIMESTAMP`` and ``INTERVAL``. +All of the date/time functions and language constructs now operate on these +types instead of ``BIGINT`` and perform temporal calculations correctly. +This was previously broken due to, for example, not being able to detect +whether an argument was a ``DATE`` or a ``TIMESTAMP``. +This change comes at the cost of breaking existing queries that perform +arithmetic operations directly on the ``BIGINT`` value returned from +the date/time functions. + +As part of this work, we have also added the :func:`date_trunc` function +which is convenient for grouping data by a time span. For example, you +can perform an aggregation by hour:: + + SELECT date_trunc('hour', timestamp_column), count(*) + FROM ... + GROUP BY 1 + +Time Zones +~~~~~~~~~~ + +This release has full support for time zone rules, which are needed to +perform date/time calculations correctly. Typically, the session time +zone is used for temporal calculations. This is the time zone of the +client computer that submits the query, if available. Otherwise, it is +the time zone of the server running the Presto coordinator. + +Queries that operate with time zones that follow daylight saving can +produce unexpected results. For example, if we run the following query +to add 24 hours using in the ``America/Los Angeles`` time zone:: + + SELECT date_add('hour', 24, TIMESTAMP '2014-03-08 09:00:00'); + => + 2014-03-09 10:00:00.000 + +The timestamp appears to only advance 23 hours. This is because on +March 9th clocks in ``America/Los Angeles`` are turned forward 1 hour, +so March 9th only has 23 hours. To advance the day part of the timestamp, +use the ``day`` unit instead:: + + SELECT date_add('day', 1, TIMESTAMP '2014-03-08 09:00:00'); + => + 2014-03-09 09:00:00.000 + +This works because the :func:`date_add` function treats the timestamp as +list of fields, adds the value to the specified field and then rolls any +overflow into the next higher field. + +Time zones are also necessary for parsing and printing timestamps. +Queries that use this functionality can also produce unexpected results. +For example, on the same machine:: + + SELECT TIMESTAMP '2014-03-09 02:30:00'; + +The above query causes an error because there was no 2:30 AM on March 9th +in ``America/Los_Angeles`` due to a daylight saving time transition. + +In addition to normal ``TIMESTAMP`` values, Presto also supports the +``TIMESTAMP WITH TIME ZONE`` type, where every value has an explicit time zone. +For example, the following query creates a ``TIMESTAMP WITH TIME ZONE``:: + + SELECT TIMESTAMP '2014-03-14 09:30:00 Europe/Berlin'; + => + 2014-03-14 09:30:00.000 Europe/Berlin + +You can also change the time zone of an existing timestamp using the +``AT TIME ZONE`` clause:: + + SELECT TIMESTAMP '2014-03-14 09:30:00 Europe/Berlin' + AT TIME ZONE 'America/Los_Angeles'; + => + 2014-03-14 01:30:00.000 America/Los_Angeles + +Both timestamps represent the same instant in time; +they differ only in the time zone used to print them. + +The time zone of the session can be set on a per-query basis using the +``X-Presto-Time-Zone`` HTTP header, or via the +``PrestoConnection.setTimeZoneId(String)`` method in the JDBC driver. + +Localization +~~~~~~~~~~~~ + +In addition to time zones, the language of the user is important when +parsing and printing date/time types. This release adds localization +support to the Presto engine and functions that require it: +:func:`date_format` and :func:`date_parse`. +For example, if we set the language to Spanish:: + + SELECT date_format(TIMESTAMP '2001-01-09 09:04', '%M'); + => + enero + +If we set the language to Japanese:: + + SELECT date_format(TIMESTAMP '2001-01-09 09:04', '%M'); + => + 1月 + +The language of the session can be set on a per-query basis using the +``X-Presto-Language`` HTTP header, or via the +``PrestoConnection.setLocale(Locale)`` method in the JDBC driver. + +Optimizations +------------- + +* We have upgraded the Hive connector to Hive 0.12 which includes + performance improvements for RCFile. + +* ``GROUP BY`` and ``JOIN`` operators are now compiled to byte code + and are significantly faster. + +* Reduced memory usage of ``GROUP BY`` and ``SELECT DISTINCT``, + which previously required several megabytes of memory + per operator, even when the number of groups was small. + +* The planner now optimizes function call arguments.

Previously, it would stop matching at the first newline. +* Add support for renaming tables using the :doc:`/sql/alter-table` statement. +* Add basic support for inserting data using the :doc:`/sql/insert` statement. + This is currently only supported for the Raptor connector. + +JSON Function Changes +--------------------- + +The :func:`json_extract` and :func:`json_extract_scalar` functions now support +the square bracket syntax:: + + SELECT json_extract(json, '$.store[book]'); + SELECT json_extract(json, '$.store["book name"]'); + +As part of this change, the set of characters allowed in a non-bracketed +path segment has been restricted to alphanumeric, underscores and colons. +Additionally, colons cannot be used in a un-quoted bracketed path segment. +Use the new bracket syntax with quotes to match elements that contain +special characters. + +Scheduler Changes +----------------- + +The scheduler now assigns splits to a node based on the current load on the node across all queries. +Previously, the scheduler load balanced splits across nodes on a per query level. Every node can have +``node-scheduler.max-splits-per-node`` splits scheduled on it. To avoid starvation of small queries, +when the node already has the maximum allowable splits, every task can schedule at most +``node-scheduler.max-pending-splits-per-node-per-task`` splits on the node. + +Row Number Optimizations +------------------------ + +Queries that use the :func:`row_number` function are substantially faster +and can run on larger result sets for two types of queries. + +Performing a partitioned limit that choses ``N`` arbitrary rows per +partition is a streaming operation. The following query selects +five arbitrary rows from ``orders`` for each ``orderstatus``:: + + SELECT * FROM ( + SELECT row_number() OVER (PARTITION BY orderstatus) AS rn, + custkey, orderdate, orderstatus + FROM orders + ) WHERE rn <= 5; + +Performing a partitioned top-N that chooses the maximum or minimum +``N`` rows from each partition now uses significantly less memory. +The following query selects the five oldest rows based on ``orderdate`` +from ``orders`` for each ``orderstatus``:: + + SELECT * FROM ( + SELECT row_number() OVER (PARTITION BY orderstatus ORDER BY orderdate) AS rn, + custkey, orderdate, orderstatus + FROM orders + ) WHERE rn <= 5; + +Use the :doc:`/sql/explain` statement to see if any of these optimizations +have been applied to your query. + +SPI Changes +----------- + +The core Presto engine no longer automatically adds a column for ``count(*)`` +queries. Instead, the ``RecordCursorProvider`` will receive an empty list of +column handles. + +The ``Type`` and ``Block`` APIs have gone through a major refactoring in this +release. The main focus of the refactoring was to consolidate all type specific +encoding logic in the type itself, which makes types much easier to implement. +You should consider ``Type`` and ``Block`` to be a beta API as we expect +further changes in the near future. + +To simplify the API, ``ConnectorOutputHandleResolver`` has been merged into +``ConnectorHandleResolver``. Additionally, ``ConnectorHandleResolver``, +``ConnectorRecordSinkProvider`` and ``ConnectorMetadata`` were modified to +support inserts. + +.. note:: + This is a backwards incompatible change with the previous connector and + type SPI, so if you have written a connector or type, you will need to update + your code before deploying this release. In particular, make sure your + connector can handle an empty column handles list (this can be verified + by running ``SELECT count(*)`` on a table from your connector). diff --git a/presto-docs/src/main/sphinx/release/release-0.76.rst b/presto-docs/src/main/sphinx/release/release-0.76.rst new file mode 100644 index 00000000..c3cba886 --- /dev/null +++ b/presto-docs/src/main/sphinx/release/release-0.76.rst @@ -0,0 +1,74 @@ +============ +Release 0.76 +============ + +Kafka Connector +--------------- + +This release adds a connector that allows querying of `Apache Kafka`_ topic data +from Presto.

In particular, it allows changing the type of a column without +changing the column type of existing partitions.

The Hive +connector now detects this scenario and fails the query after the +partition metadata has been read. + +The property ``hive.storage-format`` is broken and has been disabled.

A ``HAVING`` +clause eliminates groups that do not satisfy the given conditions. +``HAVING`` filters groups after groups and aggregates are computed. + +The following example queries the ``customer`` table and selects groups +with an account balance greater than the specified value:: + + + SELECT count(*), mktsegment, nationkey, + CAST(sum(acctbal) AS bigint) AS totalbal + FROM customer + GROUP BY mktsegment, nationkey + HAVING sum(acctbal) > 5700000 + ORDER BY totalbal DESC; + +.. code-block:: none + + _col0 | mktsegment | nationkey | totalbal + -------+------------+-----------+---------- + 1272 | AUTOMOBILE | 19 | 5856939 + 1253 | FURNITURE | 14 | 5794887 + 1248 | FURNITURE | 9 | 5784628 + 1243 | FURNITURE | 12 | 5757371 + 1231 | HOUSEHOLD | 3 | 5753216 + 1251 | MACHINERY | 2 | 5719140 + 1247 | FURNITURE | 8 | 5701952 + (7 rows) + +UNION Clause +------------ + +The ``UNION`` clause is used to combine the results of more than one +select statement into a single result set: + +.. code-block:: none + + query UNION [ALL | DISTINCT] query + +The argument ``ALL`` or ``DISTINCT`` controls which rows are included in +the final result set. If the argument ``ALL`` is specified all rows are +included even if the rows are identical. If the argument ``DISTINCT`` +is specified only unique rows are included in the combined result set. +If neither is specified, the behavior defaults to ``DISTINCT``. + +The following is an example of one of the simplest possible ``UNION`` +clauses. The following query selects the value ``13`` and combines +this result set with a second query which selects the value ``42``:: + + SELECT 13 + UNION + SELECT 42; + +.. code-block:: none + + _col0 + ------- + 13 + 42 + (2 rows) + +Multiple unions are processed left to right, unless the order is explicitly +specified via parentheses. + +ORDER BY Clause +--------------- + +The ``ORDER BY`` clause is used to sort a result set by one or more +output expressions: + +.. code-block:: none + + ORDER BY expression [ ASC | DESC ] [ NULLS { FIRST | LAST } ] [, ...] + +Each expression may be composed of output columns or it may be an ordinal +number selecting an output column by position (starting at one). The +``ORDER BY`` clause is evaluated as the last step of a query after any +``GROUP BY`` or ``HAVING`` clause. + +LIMIT Clause +------------ + +The ``LIMIT`` clause restricts the number of rows in the result set. +The following example queries a large table, but the limit clause restricts +the output to only have five rows (because the query lacks an ``ORDER BY``, +exactly which rows are returned is arbitrary):: + + SELECT orderdate FROM orders LIMIT 5; + +.. code-block:: none + + o_orderdate + ------------- + 1996-04-14 + 1992-01-15 + 1995-02-01 + 1995-11-12 + 1992-04-26 + (5 rows) + +TABLESAMPLE +----------- + +There are multiple sample methods: + +``BERNOULLI`` + Each row is selected to be in the table sample with a probability of + the sample percentage. When a table is sampled using the Bernoulli + method, all physical blocks of the table are scanned and certain + rows are skipped (based on a comparison between the sample percentage + and a random value calculated at runtime). + + The probability of a row being included in the result is independent + from any other row. This does not reduce the time required to read + the sampled table from disk. It may have an impact on the total + query time if the sampled output is processed further. + +``SYSTEM`` + This sampling method divides the table into logical segments of data + and samples the table at this granularity. This sampling method either + selects all the rows from a particular segment of data or skips it + (based on a comparison between the sample percentage and a random + value calculated at runtime). + + The rows selected in a system sampling will be dependent on which + connector is used. For example, when used with Hive, it is dependent + on how the data is laid out on HDFS. This method does not guarantee + independent sampling probabilities. + +.. note:: Neither of the two methods allow deterministic bounds on the number of rows returned. + +Examples:: + + SELECT * + FROM users TABLESAMPLE BERNOULLI (50); + + SELECT * + FROM users TABLESAMPLE SYSTEM (75); + +Using sampling with joins:: + + SELECT o.*, i.* + FROM orders o TABLESAMPLE SYSTEM (10) + JOIN lineitem i TABLESAMPLE BERNOULLI (40) + ON o.orderkey = i.orderkey; + +.. _unnest: + +UNNEST +------ + +``UNNEST`` can be used to expand an :ref:`array_type` or :ref:`map_type` into a relation. +Arrays are expanded into a single column, and maps are expanded into two columns (key, value). +``UNNEST`` can also be used with multiple arguments, in which case they are expanded into multiple columns, +with as many rows as the highest cardinality argument (the other columns are padded with nulls). +``UNNEST`` can optionally have a ``WITH ORDINALITY`` clause, in which case an additional ordinality column +is added to the end. +``UNNEST`` is normally used with a ``JOIN`` and can reference columns +from relations on the left side of the join. + +Using a single column:: + + SELECT student, score + FROM tests + CROSS JOIN UNNEST(scores) AS t (score); + +Using multiple columns:: + + SELECT numbers, animals, n, a + FROM ( + VALUES + (ARRAY[2, 5], ARRAY['dog', 'cat', 'bird']), + (ARRAY[7, 8, 9], ARRAY['cow', 'pig']) + ) AS x (numbers, animals) + CROSS JOIN UNNEST(numbers, animals) AS t (n, a);

By contrast, the GNU General Public License is intended to +guarantee your freedom to share and change free software--to make sure the +software is free for all its users. This General Public License applies to +most of the Free Software Foundation's software and to any other program whose +authors commit to using it. (Some other Free Software Foundation software is +covered by the GNU Library General Public License instead.) You can apply it to +your programs, too. + +When we speak of free software, we are referring to freedom, not price. Our +General Public Licenses are designed to make sure that you have the freedom to +distribute copies of free software (and charge for this service if you wish), +that you receive source code or can get it if you want it, that you can change +the software or use pieces of it in new free programs; and that you know you +can do these things. + +To protect your rights, we need to make restrictions that forbid anyone to deny +you these rights or to ask you to surrender the rights. These restrictions +translate to certain responsibilities for you if you distribute copies of the +software, or if you modify it. + +For example, if you distribute copies of such a program, whether gratis or for +a fee, you must give the recipients all the rights that you have. You must +make sure that they, too, receive or can get the source code. And you must +show them these terms so they know their rights. + +We protect your rights with two steps: (1) copyright the software, and (2) +offer you this license which gives you legal permission to copy, distribute +and/or modify the software. + +Also, for each author's protection and ours, we want to make certain that +everyone understands that there is no warranty for this free software. If the +software is modified by someone else and passed on, we want its recipients to +know that what they have is not the original, so that any problems introduced +by others will not reflect on the original authors' reputations. + +Finally, any free program is threatened constantly by software patents. We +wish to avoid the danger that redistributors of a free program will +individually obtain patent licenses, in effect making the program proprietary. +To prevent this, we have made it clear that any patent must be licensed for +everyone's free use or not licensed at all. + +The precise terms and conditions for copying, distribution and modification +follow. + +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + +0. This License applies to any program or other work which contains a notice +placed by the copyright holder saying it may be distributed under the terms of +this General Public License. The "Program", below, refers to any such program +or work, and a "work based on the Program" means either the Program or any +derivative work under copyright law: that is to say, a work containing the +Program or a portion of it, either verbatim or with modifications and/or +translated into another language. (Hereinafter, translation is included +without limitation in the term "modification".) Each licensee is addressed as +"you". + +Activities other than copying, distribution and modification are not covered by +this License; they are outside its scope. The act of running the Program is +not restricted, and the output from the Program is covered only if its contents +constitute a work based on the Program (independent of having been made by +running the Program). Whether that is true depends on what the Program does. + +1. You may copy and distribute verbatim copies of the Program's source code as +you receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice and +disclaimer of warranty; keep intact all the notices that refer to this License +and to the absence of any warranty; and give any other recipients of the +Program a copy of this License along with the Program. + +You may charge a fee for the physical act of transferring a copy, and you may +at your option offer warranty protection in exchange for a fee. + +2. You may modify your copy or copies of the Program or any portion of it, thus +forming a work based on the Program, and copy and distribute such modifications +or work under the terms of Section 1 above, provided that you also meet all of +these conditions: + + a) You must cause the modified files to carry prominent notices stating + that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in whole or + in part contains or is derived from the Program or any part thereof, to be + licensed as a whole at no charge to all third parties under the terms of + this License. + + c) If the modified program normally reads commands interactively when run, + you must cause it, when started running for such interactive use in the + most ordinary way, to print or display an announcement including an + appropriate copyright notice and a notice that there is no warranty (or + else, saying that you provide a warranty) and that users may redistribute + the program under these conditions, and telling the user how to view a copy + of this License. (Exception: if the Program itself is interactive but does + not normally print such an announcement, your work based on the Program is + not required to print an announcement.) + +These requirements apply to the modified work as a whole. If identifiable +sections of that work are not derived from the Program, and can be reasonably +considered independent and separate works in themselves, then this License, and +its terms, do not apply to those sections when you distribute them as separate +works. But when you distribute the same sections as part of a whole which is a +work based on the Program, the distribution of the whole must be on the terms +of this License, whose permissions for other licensees extend to the entire +whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest your +rights to work written entirely by you; rather, the intent is to exercise the +right to control the distribution of derivative or collective works based on +the Program. + +In addition, mere aggregation of another work not based on the Program with the +Program (or with a work based on the Program) on a volume of a storage or +distribution medium does not bring the other work under the scope of this +License. + +3. You may copy and distribute the Program (or a work based on it, under +Section 2) in object code or executable form under the terms of Sections 1 and +2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable source + code, which must be distributed under the terms of Sections 1 and 2 above + on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three years, to + give any third party, for a charge no more than your cost of physically + performing source distribution, a complete machine-readable copy of the + corresponding source code, to be distributed under the terms of Sections 1 + and 2 above on a medium customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer to + distribute corresponding source code. (This alternative is allowed only + for noncommercial distribution and only if you received the program in + object code or executable form with such an offer, in accord with + Subsection b above.) + +The source code for a work means the preferred form of the work for making +modifications to it. For an executable work, complete source code means all +the source code for all modules it contains, plus any associated interface +definition files, plus the scripts used to control compilation and installation +of the executable. However, as a special exception, the source code +distributed need not include anything that is normally distributed (in either +source or binary form) with the major components (compiler, kernel, and so on) +of the operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the source +code from the same place counts as distribution of the source code, even though +third parties are not compelled to copy the source along with the object code. + +4. You may not copy, modify, sublicense, or distribute the Program except as +expressly provided under this License. Any attempt otherwise to copy, modify, +sublicense or distribute the Program is void, and will automatically terminate +your rights under this License. However, parties who have received copies, or +rights, from you under this License will not have their licenses terminated so +long as such parties remain in full compliance. + +5. You are not required to accept this License, since you have not signed it. +However, nothing else grants you permission to modify or distribute the Program +or its derivative works. These actions are prohibited by law if you do not +accept this License. Therefore, by modifying or distributing the Program (or +any work based on the Program), you indicate your acceptance of this License to +do so, and all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + +6. Each time you redistribute the Program (or any work based on the Program), +the recipient automatically receives a license from the original licensor to +copy, distribute or modify the Program subject to these terms and conditions. +You may not impose any further restrictions on the recipients' exercise of the +rights granted herein. You are not responsible for enforcing compliance by +third parties to this License. + +7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), conditions +are imposed on you (whether by court order, agreement or otherwise) that +contradict the conditions of this License, they do not excuse you from the +conditions of this License. If you cannot distribute so as to satisfy +simultaneously your obligations under this License and any other pertinent +obligations, then as a consequence you may not distribute the Program at all. +For example, if a patent license would not permit royalty-free redistribution +of the Program by all those who receive copies directly or indirectly through +you, then the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply and +the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any patents or +other property right claims or to contest validity of any such claims; this +section has the sole purpose of protecting the integrity of the free software +distribution system, which is implemented by public license practices. Many +people have made generous contributions to the wide range of software +distributed through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing to +distribute software through any other system and a licensee cannot impose that +choice. + +This section is intended to make thoroughly clear what is believed to be a +consequence of the rest of this License. + +8. If the distribution and/or use of the Program is restricted in certain +countries either by patents or by copyrighted interfaces, the original +copyright holder who places the Program under this License may add an explicit +geographical distribution limitation excluding those countries, so that +distribution is permitted only in or among countries not thus excluded. In +such case, this License incorporates the limitation as if written in the body +of this License. + +9. The Free Software Foundation may publish revised and/or new versions of the +General Public License from time to time. Such new versions will be similar in +spirit to the present version, but may differ in detail to address new problems +or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any later +version", you have the option of following the terms and conditions either of +that version or of any later version published by the Free Software Foundation. +If the Program does not specify a version number of this License, you may +choose any version ever published by the Free Software Foundation. + +10. If you wish to incorporate parts of the Program into other free programs +whose distribution conditions are different, write to the author to ask for +permission. For software which is copyrighted by the Free Software Foundation, +write to the Free Software Foundation; we sometimes make exceptions for this. +Our decision will be guided by the two goals of preserving the free status of +all derivatives of our free software and of promoting the sharing and reuse of +software generally. + +NO WARRANTY + +11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR +THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE +STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE +PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, +INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND +FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND +PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, +YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + +12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL +ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE +PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR +INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA +BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER +OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. + +END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Programs + +If you develop a new program, and you want it to be of the greatest possible +use to the public, the best way to achieve this is to make it free software +which everyone can redistribute and change under these terms. + +To do so, attach the following notices to the program. It is safest to attach +them to the start of each source file to most effectively convey the exclusion +of warranty; and each file should have at least the "copyright" line and a +pointer to where the full notice is found. + + One line to give the program's name and a brief idea of what it does. + + Copyright (C) + + This program is free software; you can redistribute it and/or modify it + under the terms of the GNU General Public License as published by the Free + Software Foundation; either version 2 of the License, or (at your option) + any later version. + + This program is distributed in the hope that it will be useful, but WITHOUT + ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or + FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for + more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., 59 + Temple Place, Suite 330, Boston, MA 02111-1307 USA + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this when it +starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author Gnomovision comes + with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free + software, and you are welcome to redistribute it under certain conditions; + type 'show c' for details. + +The hypothetical commands 'show w' and 'show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may be +called something other than 'show w' and 'show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your school, +if any, to sign a "copyright disclaimer" for the program, if necessary. Here +is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + 'Gnomovision' (which makes passes at compilers) written by James Hacker. + + signature of Ty Coon, 1 April 1989 + + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library.
