Calling Flush[Async]() on the writer will NOT flush the stream.
Calling Flush[Async]() in Razor will flush both the writer and the stream.
Our normal flow will be to flush the writer, but not the stream. This
avoids chunking, but allows us to do a WriteAsync on the stream as part of
the call to FlushAsync. This is done to avoid a synchronous write due to
Dispose calling Flush on the writer, which needs to call Write on the
stream.
See issue for extensive background.
- Check MVC services once at startup
- Make action selector sync
We've never really had a scenario for the action selector being async, it
just ended up that way. None of our extensibility here lets you do
anything async without replacing it wholesale, which we don't
recommend.
- SendFileAsync does the proper fallback to stream copy when the feature
isn't available. Take advantage of it in MVC. There are plans to use the
buffer pool as part of the stream copy so MVC will get that benefit for
free.
- Left CopyToAsync in SendFileAsync when the file doesn't have a
physical path
This change avoids a state machine allocation and a dictionary allocation
on the common case (no bound properties). Ugly? You bet. Worth it? Yeah,
seems worthwhile.
This is worth about 200 bytes/request - about 3% of allocated bytes in a
smallish API scenario.
This change adds a base class for controllers to Mvc.Core that can be used
without a dependency on views, json, etc.
Most of the functionality on Controller moves to ControllerBase. I kept
the IActionFilter and IDisposable functionality on Controller since it's
not really a fit with the 'minimal' philosophy.
- Removes IExcludeTypeFilter
- Replaced with a property 'ValidateChildren' on ModelMetadata
- Teach ValidationVisitor to respect 'ValidateChildren' for enumerable
types.
The accessor for ElementMetadata can sometimes return null when
concurrently accessed.
This change solves this issue and simplified a bunch of lazy-computed
properties, by precomputing all type-related facets of ModelMetadata.
This also adds a ElementType property to ModelMetadata to maintain
the current separation of concerns as ModelMetadata is unaware of the
metadata provider.
This change removes the IActionContextAccessor as a dependency of
UrlHelper, and shifts UrlHelper to use a factory pattern. Consumers of
IUrlHelper should create an instance using the factory when needed.
This is the last part of MVC that has a dependency on IActionContext
accessor. As part of this change we no longer register it by default, and
treat it as an optional component.
This change removes the dependency of TempData on the IHttpContextAccessor
by creating an ITempDataDictionaryFactory abstraction. In general, no one
will replace the factory, it's just indirection.
This allows us to drop our dependency on IHttpContextAccessor, and move it
to the functional tests where we specifically depend on it.
The bulk of code churn here is to update tests that use TempData.
This change resolves#3512 and #3636 by removing 'magic' link generation
and adding an extension method to add routes to areas correctly using the new
pattern. This is pretty much exactly the same as how MapWebApiRoute works.
For site authors, we recommend adding area-specific routes in a way that
includes a default AND constraint for the area. Put your most specific
(for link generation) routes FIRST.
Ex:
routes.MapRoute(
"Admin/{controller}/{action}/{id?}",
defaults: new { area = "Admin" },
constraints: new { area = "Admin" });
The bulk of the changes here are to tests that unwittingly relied on the
old behavior.
This change simplifies IFormatFilter's API and removes the dependency on
IActionContext accessor.
The old API for IFormatFilter required computing state based on the
current request as part of the constructor, which in turn implied the use
of a context accessor. This isn't really needed. I didn't preserve caching of
the 'format' as that seems like an early optimization.
This is a companion change to make the RouteValueDictionary type more
promient. Using the concrete type here allows to avoid allocations in a
lot of common scenarios.
- #3428
- the `public` setter was not useful when this class is used as an attribute
- make property `virtual` to support other override patterns
- update existing test to use both override patterns
