Subject: [PATCH 02/95] Fix RendererSyncContext.Post() (#10451)

* Fix RendererSyncContext.Post()

Fixes: #9683 - SignalR connection breaks on large DOM

The root cause here is a misbehaving sync context. It's not legal for a
Post() implementation to run a callback synchronously. We want that
behavior for most of the functionality Blazor calls directly, but Post()
should always go async or else various threading primitives are broken.

* Fix incorrect tests

These tests have the assumption that setting the result of a TCS will
execution continuations synchronously. This was a bug in our
SyncContext, and these tests needed updating to be more resiliant.

* Remove a delegate allocation

Subject: [PATCH 26/95] Integrate authorization into Blazor router (#10491)

* Split AuthorizeView in two, so "Core" part can be reused from routing

* Rename LayoutDisplay to PageDisplay

* Integrate authorization with Router/PageDisplay

* CR: Replace AuthorizeViewCore.razor with AuthorizeViewCore.cs

* Update tests

* Update ref assemblies

* Add E2E tests

* Update ref assembly exclusions

* More manual ref assembly updating

* Oh these ref assemblies

Subject: [PATCH 31/95] Add runtime support for Blazor attribute splatting
 (#10357)

* Add basic tests for duplicate attributes

* Add AddMultipleAttributes improve RTB

- Adds AddMultipleAttributes
- Fix RTB to de-dupe attributes

- Add lots of tests for new RTB behaviour and EventCallback

* Harden EventCallback test

* Add new setting on ParameterAttribute

Adds the option to mark a parameter as an *extra* parameter. Why is this
on ParameterAttribute and not a new type? It makes sense to make it a
modifier on Parameter so you can use it both ways (explicitly set it, or
allow it to collect *extras*).

Added unit tests and validations for interacting with the new setting.

* Add renderer tests for 'extra' parameters

* Refactor Diagnostics for more analyzers

* Simplify analyzer and fix CascadingParameter

This is the *easy way* to write an analyzer that looks at declarations.
The information that's avaialable from symbols is much more high level
than syntax. Much of what's in this code today is needed to reverse
engineer what the compiler does already. If you use symbols you get to
benefit from all of that.

Also added validation for cascading parameters to the analyzer that I
think was just missing due to oversight.

The overall design pattern here is what I've been converging on for the
ASP.NET Core analyzers as a whole, and it seems to scale really well.

* Add analyzer for types

* Add analyzer for uniqueness

This involved a refactor to run the analyzer per-type instead of
per-property.

* Fix project file

* Adjust name

* PR feedback on PCE and more renames

* Remove unused parameter

* Fix #10398

* Add E2E test

* Pranavs cool feedback

* Optimize silent frame removal

* code check

* pr feedback

 ## Contributing code and content
 
+We accept fixes and features! Here are some resources to help you get started on how to contribute code or new content.
+
+* Look at the [Contributor documentation](/docs/) to get started on building the source code on your own.
+* ["Help wanted" issues](https://github.com/aspnet/AspNetCore/labels/help%20wanted) - these issues are up for grabs. Comment on an issue if you want to create a fix.
+* ["Good first issue" issues](https://github.com/aspnet/AspNetCore/labels/good%20first%20issue) - we think these are a good for newcomers.

 ### Identifying the scale
 
 If you would like to contribute to one of our repositories, first identify the scale of what you would like to contribute. If it is small (grammar/spelling or a bug fix) feel free to start working on a fix. If you are submitting a feature or substantial code contribution, please discuss it with the team and ensure it follows the product roadmap. You might also read these two blogs posts on contributing code: [Open Source Contribution Etiquette](http://tirania.org/blog/archive/2010/Dec-31.html) by Miguel de Icaza and [Don't "Push" Your Pull Requests](https://www.igvita.com/2011/12/19/dont-push-your-pull-requests/) by Ilya Grigorik. All code submissions will be rigorously reviewed and tested by the ASP.NET and Entity Framework teams, and only those that meet an extremely high bar for both quality and design/roadmap appropriateness will be merged into the source.

Subject: [PATCH 49/95] EndpointMiddleware does not invoke endpoint (#10650)

* EndpointMiddleware does not invoke endpoint

Fixes: #10649

The bug is that the endpoint delegate is not invoked when
SuppressCheckForUnhandledSecurityMetadata is set to true. This option is
provided so that can you suppress the security checks done by routing,
but right now what it does is suppress the entire middleware.

We had tests for the supression cases, but they didn't actually validate
that the middleware did any work, just that we don't throw. Fixed that.

* harden tests

Subject: [PATCH 52/95] Update Identity tests for EF breaking changes

Specifically:
* Removal of Relational()
* Query changes

There is some kind of flakiness still impacting these tests. It may be a race condition in EF query generation, or it may be an issue with the test infrastructure

Also, one database error page test is currently disabled.

Subject: [PATCH 53/95] Implement new bedrock listener abstraction and re-plat
 Kestrel on top (#10321)

This is a massive set of changes to Kestrel to remove the existing pubternal transport layer and implement a public facing API for listeners and clients, see the details here #10308.

This change only has the server side pieces of the story as I don't want to add the client APIs without having ported SignalR to use them. Here are the highlights:

- Transport.Abstractions is empty (will be removed in a separate PR as it requires removing it from a ton of places)
- TransportConnection has been moved to Connection.Abstractions (we can decide if we need to consolidate with DefaultConnectionContext in a later PR)
- Added FileHandleEndPoint which allows binding to a file handle (could be a pipe or tcp handle)
ListenOptions has been gutted for most pubternal API and returns various types of binding information . The source of truth is the EndPoint instance.
- Cleaned up a bunch of libuv tests decoupling them from Kestrel.Core

## Breaking changes

- Removing pubternal API is itself a breaking change but one that we already planned to do.
- We've removed the ability to set the scheduling mode on Kestrel
- DisposeAsync was added to ConnectionContext
- NoDelay was removed from ListenOptions. This has been moved to each of the transports. One major difference though is that it's no longer localized per endpoint but is global. We'd need a derived EndPoint type (or maybe extend IPEndPoint) to store both the socket options and the binding information.

Subject: [PATCH 71/95] Remove Razor versioning number from DotNetWatch.targets

Application restarts on changes to Razor files

* .cshtml and .razor files cause dotnet-watch to reload by default
* .cshtml files do not cause VS or dotnet-watch to reload when using RuntimeCompilation

Fixes https://github.com/aspnet/AspNetCore/issues/9644

+# Microsoft.AspNetCore.Authentication.Certificate
+ 
+This project sort of contains an implementation of [Certificate Authentication](https://tools.ietf.org/html/rfc5246#section-7.4.4) for ASP.NET Core. 
+Certificate authentication happens at the TLS level, long before it ever gets to ASP.NET Core, so, more accurately this is an authentication handler
+that validates the certificate and then gives you an event where you can resolve that certificate to a ClaimsPrincipal. 
+
+You **must** [configure your host](#hostConfiguration) for certificate authentication, be it IIS, Kestrel, Azure Web Applications or whatever else you're using.
+
+## Getting started
+
+First acquire an HTTPS certificate, apply it and then [configure your host](#hostConfiguration) to require certificates.
+
+In your web application add a reference to the package, then in the `ConfigureServices` method in `startup.cs` call
+`app.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme).UseCertificateAuthentication(...);` with your options, 
+providing a delegate for `OnValidateCertificate` to validate the client certificate sent with requests and turn that information 
+into an `ClaimsPrincipal`, set it on the `context.Principal` property and call `context.Success()`.
+
+If you change your scheme name in the options for the authentication handler you need to change the scheme name in 
+`AddAuthentication()` to ensure it's used on every request which ends in an endpoint that requires authorization.
+
+If authentication fails this handler will return a `403 (Forbidden)` response rather a `401 (Unauthorized)` as you
+might expect - this is because the authentication should happen during the initial TLS connection - by the time it 
+reaches the handler it's too late, and there's no way to actually upgrade the connection from an anonymous connection 
+to one with a certificate.
+
+You must also add `app.UseAuthentication();` in the `Configure` method, otherwise nothing will ever get called.
+
+For example;
+
+```c#
+public void ConfigureServices(IServiceCollection services)
+{
+    services.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)
+            .AddCertificate();
+    // All the other service configuration.
+}
+
+public void Configure(IApplicationBuilder app, IHostingEnvironment env)
+{
+    app.UseAuthentication();
+
+    // All the other app configuration.
+}
+```
+
+In the sample above you can see the default way to add certificate authentication. The handler will construct a user principal using the common certificate properties for you.
+
+## Configuring Certificate Validation
+
+The `CertificateAuthenticationOptions` handler has some built in validations that are the minimium validations you should perform on 
+a certificate. Each of these settings are turned on by default.
+
+### ValidateCertificateChain
+
+This check validates that the issuer for the certificate is trusted by the application host OS. If 
+you are going to accept self-signed certificates you must disable this check.
+
+### ValidateCertificateUse
+
+This check validates that the certificate presented by the client has the Client Authentication 
+extended key use, or no EKUs at all (as the specifications say if no EKU is specified then all EKUs 
+are valid). 
+
+### ValidateValidityPeriod
+
+This check validates that the certificate is within its validity period. As the handler runs on every 
+request this ensures that a certificate that was valid when it was presented has not expired during
+its current session.
+
+### RevocationFlag
+
+A flag which specifies which certificates in the chain are checked for revocation.
+
+Revocation checks are only performed when the certificate is chained to a root certificate.
+
+### RevocationMode 
+
+A flag which specifies how revocation checks are performed.
+Specifying an on-line check can result in a long delay while the certificate authority is contacted.
+
+Revocation checks are only performed when the certificate is chained to a root certificate.
+
+### Can I configure my application to require a certificate only on certain paths?
+
+Not possible, remember the certificate exchange is done that the start of the HTTPS conversation, 
+it's done by the host, not the application. Kestrel, IIS, Azure Web Apps don't have any configuration for
+this sort of thing.
+
+# Handler events
+
+The handler has two events, `OnAuthenticationFailed()`, which is called if an exception happens during authentication and allows you to react, and `OnValidateCertificate()` which is 
+called after certificate has been validated, passed validation, abut before the default principal has been created. This allows you to perform your own validation, for example 
+checking if the certificate is one your services knows about, and to construct your own principal. For example,
+
+```c#
+services.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)
+        .AddCertificate(options =>
+        {
+            options.Events = new CertificateAuthenticationEvents
+            {
+                OnValidateCertificate = context =>
+                {
+                    var claims = new[]
+                    {
+                        new Claim(ClaimTypes.NameIdentifier, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer),
+                        new Claim(ClaimTypes.Name, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer)
+                    };
+
+                    context.Principal = new ClaimsPrincipal(new ClaimsIdentity(claims, context.Scheme.Name));
+                    context.Success();
+
+                    return Task.CompletedTask;
+                }
+            };
+        });
+```
+
+If you find the inbound certificate doesn't meet your extra validation call `context.Fail("failure Reason")` with a failure reason.
+
+For real functionality you will probably want to call a service registered in DI which talks to a database or other type of 
+user store. You can grab your service by using the context passed into your delegates, like so
+
+```c#
+services.AddAuthentication(CertificateAuthenticationDefaults.AuthenticationScheme)
+        .AddCertificate(options =>
+        {
+            options.Events = new CertificateAuthenticationEvents
+            {
+                OnCertificateValidated = context =>
+                {
+                    var validationService =
+                        context.HttpContext.RequestServices.GetService<ICertificateValidationService>();
+                    
+                    if (validationService.ValidateCertificate(context.ClientCertificate))
+                    {
+                        var claims = new[]
+                        {
+                            new Claim(ClaimTypes.NameIdentifier, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer),
+                            new Claim(ClaimTypes.Name, context.ClientCertificate.Subject, ClaimValueTypes.String, context.Options.ClaimsIssuer)
+                        };
+
+                        context.Principal = new ClaimsPrincipal(new ClaimsIdentity(claims, context.Scheme.Name));
+                        context.Success();
+                    }                     
+
+                    return Task.CompletedTask;
+                }
+            };
+        });
+```
+Note that conceptually the validation of the certification is an authorization concern, and putting a check on, for example, an issuer or thumbprint in an authorization policy rather 
+than inside OnCertificateValidated() is perfectly acceptable.
+
+## <a name="hostConfiguration"></a>Configuring your host to require certificates
+
+### Kestrel
+
+In program.cs configure `UseKestrel()` as follows.
+
+```c#
+public static IWebHost BuildWebHost(string[] args)
+    => WebHost.CreateDefaultBuilder(args)
+    .UseStartup<Startup>()
+    .ConfigureKestrel(options =>
+    {
+        options.ConfigureHttpsDefaults(opt =>
+        {
+            opt.ClientCertificateMode = ClientCertificateMode.RequireCertificate;
+        });
+    })
+    .Build();
+```
+You must set the `ClientCertificateValidation` delegate to `CertificateValidator.DisableChannelValidation` in order to stop Kestrel using the default OS certificate validation routine and, 
+instead, letting the authentication handler perform the validation.
+
+### IIS
+
+In the IIS Manager 
+
+1. Select your Site in the Connections tab.
+2. Double click the SSL Settings in the Features View window.
+3. Check the `Require SSL` Check Box and select the `Require` radio button under Client Certificates.
+
+![Client Certificate Settings in IIS](README-IISConfig.png "Client Certificate Settings in IIS")
+
+### Azure
+
+See the [Azure documentation](https://docs.microsoft.com/en-us/azure/app-service/app-service-web-configure-tls-mutual-auth) 
+to configure Azure Web Apps then add the following to your application startup method, `Configure(IApplicationBuilder app)` add the 
+following line before the call to `app.UseAuthentication();`
+
+```c#
+app.UseCertificateHeaderForwarding();
+```
+
+### Random custom web proxies
+
+If you're using a proxy which isn't IIS or Azure's Web Apps Application Request Routing you will need to configure your proxy
+to forward the certificate it received in an HTTP header. 
+In your application startup method, `Configure(IApplicationBuilder app)`, add the 
+following line before the call to `app.UseAuthentication();`
+
+```c#
+app.UseCertificateForwarding();
+```
+
+You will also need to configure the Certificate Forwarding middleware to specify the header name.
+In your service configuration method, `ConfigureServices(IServiceCollection services)` add 
+the following code to configure the header the forwarding middleware will build a certificate from;
+
+```c#
+services.AddCertificateForwarding(options =>
+{
+    options.CertificateHeader = "YOUR_CUSTOM_HEADER_NAME";
+});
+```
+
+Finally, if your proxy is doing something weird to pass the header on, rather than base 64 encoding it 
+(looking at you nginx (╯°□°）╯︵ ┻━┻) you can override the converter option to be a func that will
+perform the optional conversion, for example 
+
+```c#
+services.AddCertificateForwarding(options =>
+{
+    options.CertificateHeader = "YOUR_CUSTOM_HEADER_NAME";
+    options.HeaderConverter = (headerValue) => 
+    {
+        var clientCertificate = 
+           /* some weird conversion logic to create an X509Certificate2 */
+        return clientCertificate;
+    }
+});
+```

Subject: [PATCH 80/95] Add analyzer to detect TagHelpers in code blocks.

- We detect `__tagHelperRunner.RunAsync` method calls in lambdas, anonymous methods, local functions, and method declarations. Upon detection we verify that the methods are `async Task` returning and if not log an error.
- Added analyzer tests to verify all the scenarios TagHelpers in code blocks can occur in.

Subject: [PATCH 83/95] Noop on the request body stream in TestServer (#10738)

* Noop on the request body stream in TestServer
- Disposable should not be observable on the client side if the server disposes the body. This is similar to how Kestrel noops on dispose to avoid common usages like StreamReader disposing the underlying stream.

Subject: [PATCH 84/95] Adds inferred [Required] for non-null ref types (#9978)

* Adds inferred [Required] for non-null ref types

Follow up from #9194

This change adds the automatic inference of [Required] for non-nullable
properties and parameters. This means that if you opt into nullable
context in C#8, we'll start treating those types as-if you put
[Required] on them.

This provides a nice invariant to rely on, namely that MVC will honor
your declared nullability contract OR report a validation error. This
reinforces the guidance already published by the C# team for using
POCOs/DTOs with nullability. See
https://github.com/aspnet/specs/blob/master/notes/3_0/nullable.md for my
analysis on the topic.

* preemptively fix PR feedback xD

* PR feedback and functional test

* more

* Fix test failures

* fix

* more

* Do a barrel roll

Subject: [PATCH 85/95] Rewrite dotnet-getdocument and GetDocument.Insider to
 retrieve all documents in one go (#10667)

- #8242 1 of 2
- save a cache file listing all retrieved documents
- remove .NET Core App 2.0 support
- remove ServiceProjectReferenceMetadata.targets, related `Project` class, and searches for a project
  - tools will run within a project and get needed information from project on command line
- roll framework forward in both tools to expand their applicability when using .NET Core
- use Microsoft.Extensions.HostFactoryResolver.Sources (part of #4923)
  - remove Microsoft.AspNetCore.Hosting.Abstractions dependency

nits:
- refactor methods in `GetDocumentCommandWorker`
- reorder option addition for consistency and to place `--help` at the top of help output
- consolidate information about method signatures at top of `GetDocumentCommandWorker`
- consolidate `try` / `catch` blocks in `GetDocumentCommandWorker`
- shorten the lifespan of a `Task`
- ensure GetDocument.Insider exit codes are unique
- make a few more `string`s `const`
- fold a few expressions over fewer lines

From 25672336f92accfa8d24823d11d0bb5528c9ad4d Mon Sep 17 00:00:00 2001
From: Doug Bunting <6431421+dougbu@users.noreply.github.com>
Date: Sun, 2 Jun 2019 22:09:42 -0700
Subject: [PATCH 86/95] Add more properties controlling service reference code
 generation (#10641)

- `$(OpenApiGenerateCodeOnBuild)` controls if targets run before compile targets
  - #4924
  - also correct multiple invocations when project has multiple target frameworks
- `$(OpenApiBuildReferencedProjects)` controls whether `@(OpenApiProjectReference)` items build automatically
  - #6582
- rename a few other properties and targets

also:
- add symbols for Microsoft.Extensions.ApiDescription.Client task assembly
  - #10508
- unconditionally run `OpenApiGetDocuments` target in referenced projects
  - corrects compilation in design-time builds
  - no longer uses `@(ProjectReferenceWithConfiguration)`; referenced project chooses all property values

nits:
- consolidate into a single `$(GenerateOpenApiCodeDependsOn)` property
- rename task assembly and namespaces in Microsoft.Extensions.ApiDesription.Client to match the project
- allow `OpenApiGetDocuments` targets to run in parallel if `$(BuildInParallel)` is enabled
- remove `$(OpenApiCodeDirectory)` normalization; never concatenated with anything else

+
+// a transform stream is a readable/writable stream where you do
+// something with the data.  Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored.  (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation.  For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes.  When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up.  When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer.  When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks.  If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk.  However,
+// a pathological inflate type of transform can cause excessive buffering
+// here.  For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output.  In this case, you could write a very small
+// amount of input, and end up with a very large amount of output.  In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform.  A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

-
-// a transform stream is a readable/writable stream where you do
-// something with the data.  Sometimes it's called a "filter",
-// but that's not a great name for it, since that implies a thing where
-// some bits pass through, and others are simply ignored.  (That would
-// be a valid example of a transform, of course.)
-//
-// While the output is causally related to the input, it's not a
-// necessarily symmetric or synchronous transformation.  For example,
-// a zlib stream might take multiple plain-text writes(), and then
-// emit a single compressed chunk some time in the future.
-//
-// Here's how this works:
-//
-// The Transform stream has all the aspects of the readable and writable
-// stream classes.  When you write(chunk), that calls _write(chunk,cb)
-// internally, and returns false if there's a lot of pending writes
-// buffered up.  When you call read(), that calls _read(n) until
-// there's enough pending readable data buffered up.
-//
-// In a transform stream, the written data is placed in a buffer.  When
-// _read(n) is called, it transforms the queued up data, calling the
-// buffered _write cb's as it consumes chunks.  If consuming a single
-// written chunk would result in multiple output chunks, then the first
-// outputted bit calls the readcb, and subsequent chunks just go into
-// the read buffer, and will cause it to emit 'readable' if necessary.
-//
-// This way, back-pressure is actually determined by the reading side,
-// since _read has to be called to start processing a new chunk.  However,
-// a pathological inflate type of transform can cause excessive buffering
-// here.  For example, imagine a stream where every byte of input is
-// interpreted as an integer from 0-255, and then results in that many
-// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
-// 1kb of data being output.  In this case, you could write a very small
-// amount of input, and end up with a very large amount of output.  In
-// such a pathological inflating mechanism, there'd be no way to tell
-// the system to stop doing the transform.  A single 4MB write could
-// cause the system to run out of memory.
-//
-// However, even in such a pathological case, only a single written chunk
-// would be consumed, and then the rest would wait (un-transformed) until
-// the results of the previous transformed chunk were consumed.

Subject: [PATCH 89/95] Make JSON case-insensitive (#10727)

* Make JSON case-insensitive

Fixes: #10724

The rationale for this change is that existing .NET client code for the
most part uses JSON.NET with its default settings (preserve property
casing). This includes the WebAPI client - which we're encouraging
everyone to use. It's not really reasonable for us to break everyone
using webapi client.

* Make separate options and add extension method

* fixit

* fix build

* fix text
