Nick Khyl	0f4c9c0ecb	cmd/viewer: import types/views when generating a getter for a map field Fixes #13873 Signed-off-by: Nick Khyl <nickk@tailscale.com>	1 month ago
Nick Khyl	03acab2639	cmd/cloner, cmd/viewer, util/codegen: add support for aliases of cloneable types We have several checked type assertions to types.Named in both cmd/cloner and cmd/viewer. As Go 1.23 updates the go/types package to produce Alias type nodes for type aliases, these type assertions no longer work as expected unless the new behavior is disabled with gotypesalias=0. In this PR, we add codegen.NamedTypeOf(t types.Type), which functions like t.(types.Named) but also unrolls type aliases. We then use it in place of type assertions in the cmd/cloner and cmd/viewer packages where appropriate. We also update type switches to include types.Alias alongside types.Named in relevant cases, remove *types.Struct cases when switching on types.Type.Underlying and update the tests with more cases where type aliases can be used.

Nick Khyl	a9dc6e07ad	util/codegen, cmd/cloner, cmd/viewer: update codegen.LookupMethod to support alias type nodes Go 1.23 updates the go/types package to produce Alias type nodes for type aliases, unless disabled with gotypesalias=0. This new default behavior breaks codegen.LookupMethod, which uses checked type assertions to types.Named and types.Interface, as only named types and interfaces have methods. In this PR, we update codegen.LookupMethod to perform method lookup on the right-hand side of the alias declaration and clearly switch on the supported type nodes types. We also improve support for various edge cases, such as when an alias is used as a type parameter constraint, and add tests for the LookupMethod function. Additionally, we update cmd/viewer/tests to include types with aliases used in type fields and generic type constraints.

Nick Khyl	f8f9f05ffe	cmd/viewer: add support for map-like container types This PR modifies viewTypeForContainerType to use the last type parameter of a container type as the value type, enabling the implementation of map-like container types where the second-to-last (usually first) type parameter serves as the key type. It also adds a MapContainer type to test the code generation. Updates #12736 Signed-off-by: Nick Khyl <nickk@tailscale.com>	3 months ago
Nick Khyl	20562a4fb9	cmd/viewer, types/views, util/codegen: add viewer support for custom container types This adds support for container-like types such as Container[T] that don't explicitly specify a view type for T. Instead, a package implementing a container type should also implement and export a ContainerView[T, V] type and a ContainerViewOf(*Container[T]) ContainerView[T, V] function, which returns a view for the specified container, inferring the element view type V from the element type T.

Nick Khyl	fd0acc4faf	cmd/cloner, cmd/viewer: add _test prefix for files generated with the test build tag Updates #12736 Signed-off-by: Nick Khyl <nickk@tailscale.com>	4 months ago
Nick Khyl	fc28c8e7f3	cmd/cloner, cmd/viewer, util/codegen: add support for generic types and interfaces This adds support for generic types and interfaces to our cloner and viewer codegens. It updates these packages to determine whether to make shallow or deep copies based on the type parameter constraints. Additionally, if a template parameter or an interface type has View() and Clone() methods, we'll use them for getters and the cloner of the owning structure.

Maisem Ali	491483d599	cmd/viewer,type/views: add MapSlice for maps of slices This abstraction provides a nicer way to work with maps of slices without having to write out three long type params. This also allows it to provide an AsMap implementation which copies the map and the slices at least. Updates tailscale/corp#20910 Signed-off-by: Maisem Ali <maisem@tailscale.com>	5 months ago

James Tucker	ab810f1f6d	cmd/cloner: add regression test for slice nil/empty semantics We had a misstep with the semantics when applying an optimization that showed up in the roll into corp. This test ensures that case and related cases must be retained. Updates #9410 Updates #9601 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
James Tucker	324f0d5f80	cmd/cloner,*: revert: optimize nillable slice cloner This reverts commit `ee90cd02fd`. The outcome is not identical for empty slices. Cloner really needs tests! Updates #9601 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
James Tucker	ee90cd02fd	cmd/cloner,*: optimize nillable slice cloner A wild @josharian appears with a good suggestion for a refactor, thanks Josh! Updates #9410 Signed-off-by: James Tucker <james@tailscale.com>	1 year ago
Maisem Ali	19a9d9037f	tailcfg: add NodeCapMap Like PeerCapMap, add a field to `tailcfg.Node` which provides a map of Capability to raw JSON messages which are deferred to be parsed later by the application code which cares about the specific capabilities. This effectively allows us to prototype new behavior without having to commit to a schema in tailcfg, and it also opens up the possibilities to develop custom behavior in tsnet applications w/o having to plumb through application specific data in the MapResponse.

James Tucker	1858ad65c8	cmd/cloner: do not allocate slices when the source is nil tailcfg.Node zero-value clone equality checks failed when I added a []*foo to the structure, as the zero value and it's clone contained a different slice header.

Brad Fitzpatrick	6e57dee7eb	cmd/viewer, types/views, all: un-special case slice of netip.Prefix Make it just a views.Slice[netip.Prefix] instead of its own named type. Having the special case led to circular dependencies in another WIP PR of mine. Updates #8948 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	1 year ago
Brad Fitzpatrick	4f454f4122	util/codegen: support embedded fields I noticed cmd/{cloner,viewer} didn't support structs with embedded fields while working on a change in another repo. This adds support. Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago

Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
