Microsoft.Data.Services.Client

Class with utility methods to help with debug only code.

Checks that the method which called this helper method was not called by any code outside of the Microsoft.Data.OData.dll.

The method is only called when in DEBUG builds, since it's quite expensive and we expect all our external callers to run DEBUG builds at least sometimes. The method is also called when compiling for FxCop analysis, as we run our official FxCop pass on RET build and we need to check that all internal methods call this one to check for accessibility even though only in debug builds.

Due to the unexpected behaviors of IAsyncResult.CompletedSynchronously in the System.Net networking stack, we have to make async calls to their APIs using the specific pattern they've prescribed. This method runs in the caller thread and invokes the BeginXXX methods. It then checks IAsyncResult.CompletedSynchronously and if it is true, we invoke the callback in the caller thread.

This is the action that invokes the BeginXXX method. Note we MUST use our special callback from GetDataServiceAsyncCallback() when invoking the async call. async callback to be called when the operation is complete A user-provided object that distinguishes this particular asynchronous request from other requests. Returns the async result from the BeginXXX method. CompletedSynchronously (for System.Net networking stack) means "was the operation completed before the first time that somebody asked if it was completed synchronously"? They do this because some of their asynchronous operations (particularly those in the Socket class) will avoid the cost of capturing and transferring the ExecutionContext to the callback thread by checking CompletedSynchronously, and calling the callback from within BeginXxx instead of on the completion port thread if the native winsock call completes quickly. For other operations however (notably those in HttpWebRequest), they use the same underlying IAsyncResult implementation, but do NOT check CompletedSynchronously before returning from BeginXxx. That means that CompletedSynchronously will be false if and only if you checked it from the thread which called BeginXxx BEFORE the operation completed. It will then continue to be false even after IsCompleted becomes true. Note that CompletedSynchronously == true does not guarantee anything about how much of your callback has executed. The usual pattern for handling synchronous completion is that both the caller and callback should check CompletedSynchronously. If its true, the callback should do nothing and the caller should call EndRead and process the result. This guarantees that the caller and callback are not accessing the stream or buffer concurrently without the need for explicit synchronization between the two.

Set the AsyncWait and invoke the user callback.

If the background thread gets a ThreadAbort, the userCallback will never be invoked. This is why it's generally important to never wait forever, but to have more specific time limit. Also then cancel the operation, to make sure its stopped, to avoid multi-threading if your wait time limit was just too short.

process the batch response

The batch reader to use for reading the batch response. an instance of the DataServiceResponse, containing individual operation responses for this batch request. The message reader for the entire batch response is stored in the this.batchMessageReader. The message reader is disposable, but this method should not dispose it itself. It will be either disposed by the caller (in case of exception) or the ownership will be passed to the returned response object (in case of success). In could also be diposed indirectly by this method when it enumerates through the responses.

1) Performance For performance reasons we use several dictionaries here: - clrMapping contains well known primitive types. Initialized in the static constructor and never changed after initialization. Therefore it is safe to read without locks. Also see comment about Binary type below - derivedPrimitiveTypeMapping - a map for custom primitive types derived from well known primitive types - especially spatial types. New items may be added at runtime so reads and writes must be locked - knownNonPrimitiveTypes - a HashSet of types we have seen and determined they are not primitive. Used to shortcircuit logic for finding derived primitive types for types we know are not primitive. To get a primitive type one *MUST NOT* clrMapping since clrMapping will not contain custom primitive types but call TryGetPrimitiveType method that knows how to handle multiple dictionaries. 2) System.Data.Linq.Binary We want to avoid static dependency on System.Data.Linq.dll. On the other hand System.Data.Linq.Binary is a well known primitive type. For performance reasons and to avoid locking the clrMapping is only initialized in the static ctor when we don't have System.Data.Linq.Binary type handy. Therefore we use the dummy BinaryTypeSub type during initialization. As a result to get a well known primitive type one *MUST NOT* use the clrMapping dictionary directly but call TryGetWellKnownPrimitiveType() method which knows how to handle BinaryType.

Clr Type - Primitive Type mapping for well known primitive types

It is being initialized in the static constructor and must not change later. This way we can avoid locking it.

Clr Type - Primitive Type mapping for custom derived primitive type (e.g. spatial types)

This dictionary contains type mapping for custom derived primitive types (e.g. spatial) that are types discovered at runtime and added as we go. Any access to this dictionary requires locking.

Edm Type - Primitive Type mapping

Analyzes projection expressions to see if supported. To be writable, must follow these rules: 1) Must be known Entity Type 2) Must be a true narrowing of the source type. Subset of properties + no transformations other then casts. To be materializable (read-only), must follow these rules 1) No transient object creation. (Entity and non-Entity types) 2) No referencing of other DataService queries or contexts.

Analyzes a lambda expression to check whether it can be satisfied with $select and client-side materialization.

Lambda expression. Resource expression in scope. Whether member accesses are matched as top-level projections. Context of expression to analyze. true if the lambda is a client-side projection; false otherwise.

Checks whether the specified refers to a sequence method call allowed on entity types.

Path-tracking object.

Type being member-init'ed.

This analyzer iterates through the list of member assignments in the MemberInitExpression and visits each one. This field tracks if the currently visited member assignment is a MemberAccessExpression, used for determining if a TryAs convert should be emitted when visited.

The associated DataServiceContext instance. DevNote(shank): this is used for determining the fully-qualified name of types when TryAs converts are processed (C# "as", VB "TryCast"). Ideally the FQN is only required during URI translation, not during analysis. However, the current code constructs the $select and $expand parts of the URI during analysis. This could be refactored in the future to defer the $select and $expand URI construction until the URI translation phase.

Expression to visit. The same expression. The projection analyzer runs after funcletization, so a member expression rather than a constant expression implies that this is correlated to a parameter, by dotting through the argument in valid cases, and possibly more complex cases in others like new DSC(p.Orders)*.Foo* <- .Foo is invalid.

Enumeration of known extension methods

Represents a reference to a bound resource set in the resource path. The type of the input reference is the element type of the set.

Because the type of the input reference is the element type of the set, it can be used to indicate what a range variable ranges over. For example, in input.Select(b => b.id), 'input' is an IQueryable of T, and 'b' is a parameter of type T. 'b' can be rebound as an input reference to 'input' by the InputBinder, which helps in query analysis and translation.

If we encounter a MethodCallExpression, we never need to lift to lift to null. This capability exists to translate certain patterns in the language. In this case, the user (or compiler) has explicitly asked for a method invocation (at which point, lifting can no longer occur).

Gets a dictionary mapping from LINQ expressions to matched by those expressions. Used to identify composite expression patterns.

Records the generated-to-source rewrites created.

Initializes a new instance.

Dictionary in which to store rewrites.

Applies normalization rewrites to the specified , recording them in the dictionary.

Expression to normalize. Dictionary in which to record rewrites. The normalized expression.

Handle binary patterns: - VB 'Is' operator - Compare patterns

CODE: x ORIGINAL: Convert(x, t) where t is assignable from typeof(x) ORIGINAL: x as t, where t is assignable from typeof(x) ORIGINAL: and typeof(x) or t are not known primitives unless typeof(x) == t ORIGINAL: and x is not a collection of entity types NORMALIZED: x

CODE: x ORIGINAL: Convert(x, typeof(object)) ORIGINAL(Funcletized): Constant(x, typeof(object)) NORMALIZED: x

Returns true if the given expression is a constant '0'.

Handles MethodCall patterns: - Operator overloads - VB operators

Handles MethodCall patterns (without recording rewrites): - Operator overloads - VB operators

Remove extra Converts from the source of Any/All/OfType methods

Identifies and normalizes any predicate argument in the given call expression. If no changes are needed, returns the existing expression. Otherwise, returns a new call expression with a normalized predicate argument.

Determines whether the given call expression has a 'predicate' argument (e.g. Where(source, predicate)) and returns the ordinal for the predicate.

Obviously this method will need to be replaced if we ever encounter a method with multiple predicates.

Determines whether the given expression of the form Lambda(Coalesce(left, Constant(false)), ...), a pattern introduced by the VB compiler for predicate arguments. Returns the 'normalized' version of the expression Lambda((bool)left, ...)

Identifies and normalizes a Select method call expression of the following form: Select(x => Convert(x)) If a match is found, it is translated into a Cast() call. This supports type casting in queries like the following: from DerivedType entity in context.Entities select entity Where DerivedType is derived from the type of context.Entities. The pattern also applies to SelectMany calls with the same structure as above. In C#, the type cast above is represented as a Cast call and the ResourceBinder knows how to handle that. In VB, the same query is translated into Select(x => Convert(x)) instead of Cast, and the ResourceBinder doesn't recognize that pattern. This normalization allows the two queries to be treated the same.

MethodCallExpression to potentially normalize. If the query pattern was found, a Cast call is returned with the same source as the original Select and a cast type that is the same as the original Convert expression. If no normalization is required, the original MethodCallExpression is returned without changes.

Looks for a method call expression of the form Select(entity => Convert(entity, DerivedType)) If found, returns DerivedType.

Expression to check for pattern match. If the match was found, this is the type used in the Convert, otherwise null. True if the expression matches the desired pattern, otherwise false.

Looks for a lambda expression of the form related => Convert(related, DerivedType) Returns DerivedType if a match was found.

Expression to check for pattern match. If the matches the pattern, this is the type of the found Convert call, otherwise null. True if the expression matches the desired pattern, otherwise false.

This method exists solely to support creation of valid relational operator LINQ expressions that are not natively supported by the CLR (e.g. String > String). This method must not be invoked.

Create an operator relating 'left' and 'right' given a relational operator.

Try to create an operator relating 'left' and 'right' using the given operator. If the given operator does not define a known relation, returns false.

CODE(C#): Class.Compare(left, right) ORIGINAL: MethodCallExpression(Compare, left, right) NORMALIZED: Condition(Equal(left, right), 0, Condition(left > right, 1, -1)) Why is this an improvement? We know how to evaluate Condition in the store, but we don't know how to evaluate MethodCallExpression... Where the CompareTo appears within a larger expression, e.g. left.CompareTo(right) > 0, we can further simplify to left > right (we register the "ComparePattern" to make this possible).

Records a rewritten expression as necessary.

Original source expression. Rewritten expression. IMPORTANT: if there are higher-level rewrites such as replacing parameter references, the lower-level rewrites will become un-doable in other contexts; we will have to change normalization/de-normalization strategy, record additional mapping information and/or bubble up the rewrite tracking.

Records the generated-to-source rewrites created.

This class provides a Bind method that analyzes an input and returns a bound tree.

The associated DataServiceContext instance. DevNote(shank): this is used for determining the fully-qualified name of types when TypeAs converts are processed (C# "as", VB "TryCast"). Ideally the FQN is only required during URI translation, not during analysis. However, the current code constructs the $select and $expand parts of the URI during analysis. This could be refactored in the future to defer the $select and $expand URI construction until the URI translation phase.

Convenience property: model.

Use this class to perform pattern-matching over expression trees.

Following these guidelines simplifies usage: - Return true/false for matches, and interesting matched information in out parameters. - If one of the inputs to be matched undergoes "skipping" for unnecesary converts, return the same member as an out parameter. This forces callers to be aware that they should use the more precise representation for computation (without having to rely on a normalization step).

Note that C# and VB.NET have different patterns for accumulating parameters. C# uses a two-member anonymous type with "everything so far" plus the newly introduced range variable. VB.NET uses an n-member anonymous type by pulling range variables from a previous anonymous type (or the first range variable), plus the newly introduced range variable. For additional background, see: Transparent Identifiers - http://blogs.msdn.com/wesdyer/archive/2006/12/22/transparent-identifiers.aspx http://msdn.microsoft.com/en-us/library/bb308966.aspx In particular: - 26.7.1.4 From, let, where, join and orderby clauses - 26.7.1.7 Transparent identifiers is the expression that represents the navigation resulting from the collector selector in the SelectMany() call under analysis.

Collection of entity objects to be added to the . When tracking is enabled, the behavior of Load would be to attach all those entities that are not already tracked by the context associated with the collection. The operation will go deep into the input entities so that all related entities are attached to the context if not already present. All entities in will be tracked after Load is done. Load method checks for duplication. The collection will ignore any duplicated items been loaded. For large amount of items, consider DataServiceContext.LoadProperty instead.

Class which contains all the logic for resolving the type from the wire name.

Dictionary instance to map the edm type name to the client type annotation. In V1/V2, we never used to cache this and call this during materialization. Hence 2 different contexts can resolve the same wire type differently and that would have been fine. Also, someone could have written a logic that might differ based on queries within the same context. For e.g. before executing a projection query, the user can set a flag so that the resolver behaves differently. Hence caching this locally for every request to simulate that behavior.

Resolves the client type that should be used for materialization.

Expected client clr type based on the API called. The name surfaced by the ODataLib reader. If we have a server model, this will be a server type name that needs to be resolved. If not, then this will already be a client type name. The resolved annotation for the client type to materialize into.

Resolves the expected EDM type to give to the ODataLib reader based on a client CLR type.

The client side CLR type. The resolved EDM type to provide to ODataLib.

Determines whether or not the client type should be written for a property that is not defined on the server. DEVNOTE: If there is no server model, the declaring type is complex, or the server type cannot be found then the server type will be assumed to match the client type. This is done this way to prevent getting this wrong if the server property is defined, but we cannot find it for some reason. So if the types do not match, or we aren't able to align them, we will not write the type name, allowing the server to interpret it as the correct type.

It also gives us a place to invoke internal test hook callbacks that can validate the response headers, and also so that we can do debug validation to make sure that the headers have not changed since they were originally configured on the request.

HttpWebRequest instance IAsyncResult for EndGetResponse if this is an async call. If set to true, this method will only re-throw the WebException that was caught if the response in the exception is null. If set to false, this method will always re-throw in case of a WebException. Returns the HttpWebResponse from the wrapped GetSyncronousResponse method.

Occurs when a new has been created.

This event is fired before a request is sent to the server, giving the handler the opportunity to inspect, adjust and/or replace the WebRequest object used to perform the request. When calling BeginSaveChanges and not using SaveChangesOptions.Batch and SaveChangesOptions.BatchWithIndependentOperations, this event may be raised from a different thread.

This event is fired before a request is sent to the server, giving the handler the opportunity to inspect, adjust and/or replace the WebRequest object used to perform the request.

When calling BeginSaveChanges and not using SaveChangesOptions.Batch and SaveChangesOptions.BatchWithIndependentOperations, this event may be raised from a different thread.

This event is fired before a request message object is built, giving the handler the opportunity to inspect, adjust and/or replace some request information before the message is built. This event should be used to modify the outgoing Url of the request or alter request headers. After the request is built, other modifications on the WebRequest object can be made in SendingRequest2.

When calling BeginSaveChanges and not using SaveChangesOptions.Batch and SaveChangesOptions.BatchWithIndependentOperations, this event may be raised from a different thread.

Occurs after entity data has been completely read into the entity object.

This event fires once an entry has been read into a .NET object but before the serializer returns to the caller, giving handlers an opporunity to read further information from the incoming ATOM entry and updating the object. This event should only be raised from the thread that was used to invoke Execute, EndExecute, SaveChanges, EndSaveChanges.

This event fires when a response is received by the client. It fires for both top level responses and each operation or query within a batch response.

On top level requests, the event is fired before any processing is done. For inner batch operations, the event is also fired before any processing is done, with the exception that the content-ID of a changeset operation will be read before the event is fired.

Occurs after an entity has been fully serialized into XML in a request message.

This event fires once an ATOM entry is ready to be written to the network for a request, giving handlers an opportunity to customize the entry with information from the corresponding .NET object or the environment. When calling BeginSaveChanges and not using SaveChangesOptions.Batch and SaveChangesOptions.BatchWithIndependentOperations, this event may be raised from a different thread.

This event fires when SaveChanges or EndSaveChanges is called
