It seems hard to find a common pattern of checking types in `Expression`. Sometimes we know what input types we need(like `And`, we know we need two booleans), sometimes we just have some rules(like `Add`, we need 2 numeric types which are equal). So I defined a general interface `checkInputDataTypes` in `Expression` which returns a `TypeCheckResult`. `TypeCheckResult` can tell whether this expression passes the type checking or what the type mismatch is.
This PR mainly works on apply input types checking for arithmetic and predicate expressions.
TODO: apply type checking interface to more expressions.

a2211ca [Reynold Xin] [SPARK-7976] Enable NoFinalizeChecker.
Spark's `ExternalSorter` writes shuffle output files during sort-based shuffle. Sort-shuffle contains a configuration, `spark.shuffle.sort.bypassMergeThreshold`, which causes ExternalSorter to skip sorting and merging and simply write separate files per partition, which are then concatenated together to form the final map output file.
The code paths used during this bypass are almost completely separate from ExternalSorter's other code paths, so refactoring them into a separate file can significantly simplify the code.
In addition to re-arranging code, this patch deletes a bunch of dead code. The main entry point into ExternalSorter is `insertAll()` and in SPARK-4479 / #3422 this method was modified to completely bypass in-memory buffering of records when `bypassMergeSort` takes effect. As a result, some of the spilling and merging code paths will no longer be called when `bypassMergeSort` is used, so we should be able to safely remove that code.
There's an open JIRA ([SPARK-6026](https://issues.apache.org/jira/browse/SPARK-6026)) for removing the `bypassMergeThreshold` parameter and code paths; I have not done that here, but the changes in this patch will make removing that parameter significantly easier if we ever decide to do that.
This patch also makes several improvements to shuffle-related tests and adds more defensive checks to certain shuffle classes:
- DiskBlockObjectWriter now throws an exception if `fileSegment()` is called before `commitAndClose()` has been called.
- DiskBlockObjectWriter's close methods are now idempotent, so calling any of the close methods twice in a row will no longer result in incorrect shuffle write metrics changes. Calling `revertPartialWritesAndClose()` on a closed DiskBlockObjectWriter now has no effect (before, it might mess up the metrics).
- The end-to-end shuffle record count metrics tests have been moved from InputOutputMetricsSuite to ShuffleSuite. This means that these tests will now be run against all shuffle implementations rather than just the default shuffle configuration.
- The end-to-end metrics tests now include a test of a job which performs aggregation in the shuffle.
- Our tests now check that `shuffleBytesWritten == totalShuffleBytesRead`.
- FileSegment now throws IllegalArgumentException if it is constructed with a negative length or offset.

* As spark now supports long running service by updating tokens for namenode, but only accept parameters passed with "--k=v" format which is not very convinient. This patch add spark.* configs in properties file and system property.
* --principal and --keytabl options are passed to client but when we started thrift server or spark-shell these two are also passed into the Main class (org.apache.spark.sql.hive.thriftserver.HiveThriftServer2 and org.apache.spark.repl.Main).
In these two main class, arguments passed in will be processed with some 3rd libraries, which will lead to some error: "Invalid option: --principal" or "Unrecgnised option: --principal".
We should pass these command args in different forms, say system properties.

Shutdown hook for temp directories had priority 100 while SparkContext was 50. So the local root directory was deleted before SparkContext was shutdown. This leads to scary errors on running jobs, at the time of shutdown. This is especially a problem when running streaming examples, where Ctrl-C is the only way to shutdown.
The fix in this PR is to make the temp directory shutdown priority lower than SparkContext, so that the temp dirs are the last thing to get deleted, after the SparkContext has been shut down. Also, the DiskBlockManager shutdown priority is change from default 100 to temp_dir_prio + 1, so that it gets invoked just before all temp dirs are cleared.

The existing code rounds down to the nearest percent when computing the proportion
of a task's time that was spent on each phase of execution, and then computes
the scheduler delay proportion as 100 - sum(all other proportions). As a result,
a few extra percent can end up in the scheduler delay. This commit eliminates
the rounding so that the time visualizations correspond properly to the real times.

reason to round here that I missed.

This is a somewhat obscure bug, but I think that it will seriously impact KryoSerializer users who use custom registrators which disabled auto-reset. When auto-reset is disabled, then this breaks things in some of our shuffle paths which actually end up creating multiple OutputStreams from the same shared SerializerInstance (which is unsafe).
This was introduced by a patch (SPARK-3386) which enables serializer re-use in some of the shuffle paths, since constructing new serializer instances is actually pretty costly for KryoSerializer. We had already fixed another corner-case (SPARK-7766) bug related to this, but missed this one.
I think that the root problem here is that KryoSerializerInstance can be used in a way which is unsafe even within a single thread, e.g. by creating multiple open OutputStreams from the same instance or by interleaving deserialize and deserializeStream calls. I considered a smaller patch which adds assertions to guard against this type of "misuse" but abandoned that approach after I realized how convoluted the Scaladoc became.
This patch fixes this bug by making it legal to create multiple streams from the same KryoSerializerInstance. Internally, KryoSerializerInstance now implements a `borrowKryo()` / `releaseKryo()` API that's backed by a "pool" of capacity 1. Each call to a KryoSerializerInstance method will borrow the Kryo, do its work, then release the serializer instance back to the pool. If the pool is empty and we need an instance, it will allocate a new Kryo on-demand. This makes it safe for multiple OutputStreams to be opened from the same serializer. If we try to release a Kryo back to the pool but the pool already contains a Kryo, then we'll just discard the new Kryo. I don't think there's a clear benefit to having a larger pool since our usages tend to fall into two cases, a) where we only create a single OutputStream and b) where we create a huge number of OutputStreams with the same lifecycle, then destroy the KryoSerializerInstance (this is what's happening in the bypassMergeSort code path that my regression test hits).

**Reproduction.** Run a long-running job, go to the job page, expand the DAG visualization, and click into a stage. Your stage is now killed. Why? This is because the visualization code just reaches into the stage table and grabs the first link it finds. In our case, this first link happens to be the kill link instead of the one to the stage page.
**Fix.** Use proper CSS selectors to avoid ambiguity.

My experiments with scheduling very short tasks in standalone cluster mode indicated that a significant amount of time was being spent in scheduling the tasks (>500ms for 256 tasks). I found that most of the time was being spent in creating a new instance of serializer for each task. Changing this to just one serializer brought down the scheduling time to 8ms.

The previous PR for SPARK-7224 (#5790) broke JDK 6, because it used java.nio.Path, which was in jdk 7, and not in 6. This PR uses Guava's `Files` to handle directory creation, and etc...
The description from the previous PR:
> This patch contains an `IvyTestUtils` file, which dynamically generates jars and pom files to test the `--packages` feature without having to rely on the internet, and Maven Central.
cc pwendell
I also rand the flaky test about 20 times locally, it didn't fail a single time, but I think it may fail like once every 100 builds? I still haven't figured the cause yet, but the test before it, `--jars` was also failing after we turned off the `--packages` test in `SparkSubmitSuite`. It may be related to the launch of SparkSubmit.

When initializing `executionHive`, we only masks
`javax.jdo.option.ConnectionURL` to override metastore location. However,
other properties that relates to the actual Hive metastore data source are not
masked. For example, when using Spark SQL with a PostgreSQL backed Hive
metastore, `executionHive` actually tries to use settings read from
`hive-site.xml`, which talks about PostgreSQL, to connect to the temporary
Derby metastore, thus causes error.
To fix this, we need to mask all metastore data source properties.
Specifically, according to the code of [Hive `ObjectStore.getDataSourceProps()`
method] [1], all properties whose name mentions "jdo" and "datanucleus" must be
included.
[1]: https://github.com/apache/hive/blob/release-0.13.1/metastore/src/java/org/apache/hadoop/hive/metastore/ObjectStore.java#L288
Have tested using postgre sql as metastore, it worked fine.

SPARK-3386 / #5606 modified the shuffle write path to re-use serializer instances across multiple calls to DiskBlockObjectWriter. It turns out that this introduced a very rare bug when using `KryoSerializer`: if auto-reset is disabled and reference-tracking is enabled, then we'll end up re-using the same serializer instance to write multiple output streams without calling `reset()` between write calls, which can lead to cases where objects in one file may contain references to objects that are in previous files, causing errors during deserialization.
This patch fixes this bug by calling `reset()` at the start of `serialize()` and `serializeStream()`. I also added a regression test which demonstrates that this problem only occurs when auto-reset is disabled and reference-tracking is enabled.

Two main changes:
Add two functions in ExternalBlockManager, which are putValues and getValues
because the implementation may not rely on the putBytes and getBytes
improve Tachyon integration.
Currently, when putting data into Tachyon, Spark first serialize all data in one partition into a ByteBuffer, and then write into Tachyon, this will uses much memory and increase GC overhead
when get data from Tachyon, getValues depends on getBytes, which also read all data into On heap byte arry, and result in much memory usage.
This PR changes the approach of the two functions, make them read / write data by stream to reduce memory usage.
In our testing, when data size is huge, this patch reduces about 30% GC time and 70% full GC time, and total execution time reduces about 10%

This patch fixes two things:
**SPARK-7627.** Cached RDDs no longer light up on the job page. This is a simple fix.
**SPARK-7472.** Display skipped stages differently from normal stages.
The latter is a major UX issue. Because we link the job viz to the stage viz even for skipped stages, the user may inadvertently click into the stage page of a skipped stage, which is empty.

Learnt a lesson from SPARK-7655: Spark should avoid to use `scala.concurrent.ExecutionContext.Implicits.global` because the user may submit blocking actions to `scala.concurrent.ExecutionContext.Implicits.global` and exhaust all threads in it. This could crash Spark. So Spark should always use its own thread pools for safety.
This PR removes all usages of `scala.concurrent.ExecutionContext.Implicits.global` and uses proper thread pools to replace them.

We can remove this workaround if we upgrade to a snappy-java version that contains my fix for this bug, but in the meantime this patch offers a backportable Spark fix.

Because both `AkkaRpcEndpointRef.ask` and `BroadcastHashJoin` uses `scala.concurrent.ExecutionContext.Implicits.global`. However, because the tasks in `BroadcastHashJoin` are usually long-running tasks, which will occupy all threads in `global`. Then `ask` cannot get a chance to process the replies.
For `ask`, actually the tasks are very simple, so we can use `MoreExecutors.sameThreadExecutor()`. For `BroadcastHashJoin`, it's better to use `ThreadUtils.newDaemonCachedThreadPool`.

This commit cleans up some unnecessary code, eliminates the feature where when you mouse-over a box in the timeline, the corresponding task is highlighted in the table (because that feature is only useful in the rare case when you have a very small number of tasks, in which case it's easy to figure out the mapping anyway), and fixes a bug where nothing shows up if you try to visualize a stage with only 1 task.

27329d9 [Tim Ellison] [CORE] Protect additional test vars from early GC
<h3>Description</h3>
Detect REPL mode once per JVM lifespan.
Previous behavior was to check presence of interpreter mode every time a job was submitted. In the case of execution of multiple short-living jobs this was causing massive mutual blocks between submission threads.
For more details please refer to https://issues.apache.org/jira/browse/SPARK-7233.
<h3>Notes</h3>
* I inverted the return value in case of catching an exception from `true` to `false`. It seems more logical to assume that if the REPL class is not found, we aren't in the interpreter mode.
* I'd personally would call `classForName` with just a Spark classloader (`org.apache.spark.util.Utils#getSparkClassLoader`) but `org.apache.spark.util.Utils#getContextOrSparkClassLoader` is said to be preferable.
* I struggled to come up with a concise, readable and clear unit test. Suggestions are welcome if you feel necessary.

This patch introduces a new shuffle manager that enhances the existing sort-based shuffle with a new cache-friendly sort algorithm that operates directly on binary data. The goals of this patch are to lower memory usage and Java object overheads during shuffle and to speed up sorting. It also lays groundwork for follow-up patches that will enable end-to-end processing of serialized records.
The new shuffle manager, `UnsafeShuffleManager`, can be enabled by setting `spark.shuffle.manager=tungsten-sort` in SparkConf.
The new shuffle manager uses directly-managed memory to implement several performance optimizations for certain types of shuffles. In cases where the new performance optimizations cannot be applied, the new shuffle manager delegates to SortShuffleManager to handle those shuffles.
UnsafeShuffleManager's optimizations will apply when _all_ of the following conditions hold:
- The shuffle dependency specifies no aggregation or output ordering.
- The shuffle serializer supports relocation of serialized values (this is currently supported
by KryoSerializer and Spark SQL's custom serializers).
- The shuffle produces fewer than 16777216 output partitions.
- No individual record is larger than 128 MB when serialized.
In addition, extra spill-merging optimizations are automatically applied when the shuffle compression codec supports concatenation of serialized streams. This is currently supported by Spark's LZF serializer.
At a high-level, UnsafeShuffleManager's design is similar to Spark's existing SortShuffleManager. In sort-based shuffle, incoming records are sorted according to their target partition ids, then written to a single map output file. Reducers fetch contiguous regions of this file in order to read their portion of the map output. In cases where the map output data is too large to fit in memory, sorted subsets of the output can are spilled to disk and those on-disk files are merged to produce the final output file.
UnsafeShuffleManager optimizes this process in several ways:
- Its sort operates on serialized binary data rather than Java objects, which reduces memory consumption and GC overheads. This optimization requires the record serializer to have certain properties to allow serialized records to be re-ordered without requiring deserialization. See SPARK-4550, where this optimization was first proposed and implemented, for more details.
- It uses a specialized cache-efficient sorter (UnsafeShuffleExternalSorter) that sorts arrays of compressed record pointers and partition ids. By using only 8 bytes of space per record in the sorting array, this fits more of the array into cache.
- The spill merging procedure operates on blocks of serialized records that belong to the same partition and does not need to deserialize records during the merge.
- When the spill compression codec supports concatenation of compressed data, the spill merge simply concatenates the serialized and compressed spill partitions to produce the final output partition. This allows efficient data copying methods, like NIO's `transferTo`, to be used and avoids the need to allocate decompression or copying buffers during the merge.
The shuffle read path is unchanged.
This patch is similar to [SPARK-4550](http://issues.apache.org/jira/browse/SPARK-4550) / #4450 but uses a slightly different implementation. The `unsafe`-based implementation featured in this patch lays the groundwork for followup patches that will enable sorting to operate on serialized data pages that will be prepared by Spark SQL's new `unsafe` operators (such as the new aggregation operator introduced in #5725).
### Future work
There are several tasks that build upon this patch, which will be left to future work:
- [SPARK-7271](https://issues.apache.org/jira/browse/SPARK-7271) Redesign / extend the shuffle interfaces to accept binary data as input. The goal here is to let us bypass serialization steps in cases where the sort input is produced by an operator that operates directly on binary data.
- Extension / redesign of the `Serializer` API. We can add new methods which allow serializers to determine the size requirements for serializing objects and for serializing objects directly to a specified memory address (similar to how `UnsafeRowConverter` works in Spark SQL).

This fixes the label bleeding issue described in the JIRA and pictured in the screenshots below. I also took the opportunity to move some code to the places that they belong more to. In particular:
(1) Drawing cluster labels is now implemented in my branch of dagre-d3 instead of in Spark
(2) All graph styling is now moved from Scala to JS
Note that these changes are related because our existing mechanism of "tacking on cluster labels" afterwards isn't flexible enough for us to fix issues like this one easily. For the other half of the changes, visit http://github.com/andrewor14/dagre-d3.

This PR adds partitioning support for the external data sources API. It aims to simplify development of file system based data sources, and provide first class partitioning support for both read path and write path. Existing data sources like JSON and Parquet can be simplified with this work.
## New features provided
1. Hive compatible partition discovery
This actually generalizes the partition discovery strategy used in Parquet data source in Spark 1.3.0.
1. Generalized partition pruning optimization
Now partition pruning is handled during physical planning phase. Specific data sources don't need to worry about this harness anymore.
(This also implies that we can remove `CatalystScan` after migrating the Parquet data source, since now we don't need to pass Catalyst expressions to data source implementations.)
1. Insertion with dynamic partitions
When inserting data to a `FSBasedRelation`, data can be partitioned dynamically by specified partition columns.
## New structures provided
### Developer API
1. `FSBasedRelation`
Base abstract class for file system based data sources.
1. `OutputWriter`
Base abstract class for output row writers, responsible for writing a single row object.
1. `FSBasedRelationProvider`
A new relation provider for `FSBasedRelation` subclasses. Note that data sources extending `FSBasedRelation` don't need to extend `RelationProvider` and `SchemaRelationProvider`.
### User API
New overloaded versions of
1. `DataFrame.save()`
1. `DataFrame.saveAsTable()`
1. `SQLContext.load()`
are provided to allow users to save/load DataFrames with user defined dynamic partition columns.
### Spark SQL query planning
1. `InsertIntoFSBasedRelation`
Used to implement write path for `FSBasedRelation`s.
1. New rules for `FSBasedRelation` in `DataSourceStrategy`
These are added to hook `FSBasedRelation` into physical query plan in read path, and perform partition pruning.
## TODO
- [ ] Use scratch directories when overwriting a table with data selected from itself.
Currently, this is not supported, because the table been overwritten is always deleted before writing any data to it.
- [ ] When inserting with dynamic partition columns, use external sorter to group the data first.
This ensures that we only need to open a single `OutputWriter` at a time. For data sources like Parquet, `OutputWriter`s can be quite memory consuming. One issue is that, this approach breaks the row distribution in the original DataFrame. However, we did't promise to preserve data distribution when writing a DataFrame.
- [x] More tests. Specifically, test cases for
- [x] Self-join
- [x] Loading partitioned relations with a subset of partition columns stored in data files.
- [x] `SQLContext.load()` with user defined dynamic partition columns.
## Parquet data source migration
Parquet data source migration is covered in PR https://github.com/liancheng/spark/pull/6, which is against this PR branch and for preview only. A formal PR need to be made after this one is merged.

Patch for SPARK-7508
This logs warn then generates a response which include the message body and stack trace as text/plain, no-cache. The exit code is 500.
In practise (in some tests in SPARK-1537 to be precise), jetty is getting in between this servlet and the web response the user sees —the body of the response is lost for any error response (500, even 404 and bad request). The standard Jetty handlers must be getting in the way.
This patch doesn't address that, it ensures that
1. if the jetty handlers were put to one side the users would see the errors
2. at least the exceptions appear in the server-side logs.
This is better to users saying "I saw a 500 error" and you not having anything in the logs to see what went wrong.

When we use Spark on YARN and have AllJobPage via ResourceManager's proxy, the link URL in objects which represent each job on timeline view is wrong.
In timeline-view.js, the link is generated as follows.
```
window.location.href = "job/?id=" + getJobId(this);
```
This assumes the URL displayed on the web browser ends with "jobs/" but when we access AllJobPage via the proxy, the url displayed does not end with "jobs/"
The proxy doesn't return status code 301 or 302 so the url displayed still indicates the base url, not "/jobs" even though displaying AllJobPages.

The DAG visualization currently displays only low-level Spark primitives (e.g. `map`, `reduceByKey`, `filter` etc.). For SQL, these aren't particularly useful. Instead, we should display higher level physical operators (e.g. `Filter`, `Exchange`, `ShuffleHashJoin`). cc marmbrus

The code was treating deep links as if they were attempt IDs, so
for example if you tried to load "/history/app1/jobs" directly,
that would fail because the code would treat "jobs" as an attempt id.
This change modifies the code to try both cases - first without an
attempt id, then with it, so that deep links are handled correctly.
This assumes that the links in the Spark UI do not clash with the
attempt id namespace, though, which is the case for YARN at least,
which is the only backend that currently publishes attempt IDs.

This patch extends the `Serializer` interface with a new `Private` API which allows serializers to indicate whether they support relocation of serialized objects in serializer stream output.
This relocatibilty property is described in more detail in `Serializer.scala`, but in a nutshell a serializer supports relocation if reordering the bytes of serialized objects in serialization stream output is equivalent to having re-ordered those elements prior to serializing them. The optimized shuffle path introduced in #4450 and #5868 both rely on serializers having this property; this patch just centralizes the logic for determining whether a serializer has this property. I also added tests and comments clarifying when this works for KryoSerializer.
This change allows the optimizations in #4450 to be applied for shuffles that use `SqlSerializer2`.

Exposes data available in the UI as json over http. Key points:
* new endpoints, handled independently of existing XyzPage classes. Root entrypoint is `JsonRootResource`
* Uses jersey + jackson for routing & converting POJOs into json
* tests against known results in `HistoryServerSuite`
* also fixes some minor issues w/ the UI -- synchronizing on access to `StorageListener` & `StorageStatusListener`, and fixing some inconsistencies w/ the way we handle retained jobs & stages.

"The best way to size the amount of memory consumption your dataset will require is to create an RDD, put it into cache, and look at the SparkContext logs on your driver program. The logs will tell you how much memory each partition is consuming, which you can aggregate to get the total size of the RDD."

This is a pain. It would be much nicer to expose simply functionality for understanding the memory footprint of a Java object.

This patch adds the functionality to display the RDD DAG on the SparkUI.
This DAG describes the relationships between
- an RDD and its dependencies,
- an RDD and its operation scopes, and
- an RDD's operation scopes and the stage / job hierarchy
An operation scope here refers to the existing public APIs that created the RDDs (e.g. `textFile`, `treeAggregate`). In the future, we can expand this to include higher level operations like SQL queries.
*Note: This blatantly stole a few lines of HTML and JavaScript from #5547 (thanks shroffpradyumn!)*
Here's what the job page looks like:

This PR adds initial support for loading multiple versions of Hive in a single JVM and provides a common interface for extracting metadata from the `HiveMetastoreClient` for a given version. This is accomplished by creating an isolated `ClassLoader` that operates according to the following rules:
- __Shared Classes__: Java, Scala, logging, and Spark classes are delegated to `baseClassLoader`
allowing the results of calls to the `ClientInterface` to be visible externally.
- __Hive Classes__: new instances are loaded from `execJars`. These classes are not
accessible externally due to their custom loading.
- __Barrier Classes__: Classes such as `ClientWrapper` are defined in Spark but must link to a specific version of Hive. As a result, the bytecode is acquired from the Spark `ClassLoader` but a new copy is created for each instance of `IsolatedClientLoader`.
This new instance is able to see a specific version of hive without using reflection where ever hive is consistent across versions. Since
this is a unique instance, it is not visible externally other than as a generic
`ClientInterface`, unless `isolationOn` is set to `false`.
In addition to the unit tests, I have also tested this locally against mysql instances of the Hive Metastore. I've also successfully ported Spark SQL to run with this client, but due to the size of the changes, that will come in a follow-up PR.
By default, Hive jars are currently downloaded from Maven automatically for a given version to ease packaging and testing. However, there is also support for specifying their location manually for deployments without internet.

3f80640 [Ye Xianjin] The size of Integer class changes from 24 to 16 on a 64-bit JVM with -UseCompressedOops flag on after the fix. I don't how 100000 was originally calculated, It looks like 100000 is the magic number which makes sure spilling. Because of the size change, It fails because there is no spilling at all. Change the number to a slightly larger number fixes that.
e849d2d [Ye Xianjin] Merge two shellSize assignments into one. Add some explanation to alignSizeUp method.
85a0b51 [Ye Xianjin] Fix typos and update wording in comments. Using alignSizeUp to compute alignSize.
d27eb77 [Ye Xianjin] Add some detailed comments in the code. Add some test cases. It's very difficult to design test cases as the final object alignment will hide a lot of filed layout details if we just considering the whole size.
842aed1 [Ye Xianjin] primitiveSize(cls) can just return Int. Use a simplified class field layout method to calculate class instance size. Will add more documents and test cases. Add a new alignSizeUp function which uses bitwise operators to speedup.
62e8ab4 [Ye Xianjin] Don't alignSize for objects' shellSize, alignSize when added to state.size. Add some primitive wrapper objects size tests.

Closes#5862 from mridulm/optimize_aggregator and squashes the following commits:
61cf43a [Mridul Muralidharan] Use insertAll instead of insert - much more expensive to do it per tuple
Note: ~600 lines of this is test code, and ~100 lines documentation.
**[SPARK-7121]** ClosureCleaner does not handle nested closures properly. For instance, in SparkContext, I tried to do the following:
```
def scope[T](body: => T): T = body // no-op
def myCoolMethod(path: String): RDD[String] = scope {
parallelize(1 to 10).map { _ => path }
}
```
and I got an exception complaining that SparkContext is not serializable. The issue here is that the inner closure is getting its path from the outer closure (the scope), but the outer closure references the SparkContext object itself to get the `parallelize` method.
Note, however, that the inner closure doesn't actually need the SparkContext; it just needs a field from the outer closure. If we modify ClosureCleaner to clean the outer closure recursively using only the fields accessed by the inner closure, then we can serialize the inner closure.
**[SPARK-7120]** Also, the other thing is that this file is one of the least understood, partly because it is very low level and is written a long time ago. This patch attempts to change that by adding the missing documentation.
This is blocking my effort on a separate task #5729.
