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	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.

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.

Maisem Ali	1ecc16da5f	tailcfg,ipn/ipnlocal,wgengine: add values to PeerCapabilities Define PeerCapabilty and PeerCapMap as the new way of sending down inter-peer capability information. Previously, this was unstructured and you could only send down strings which got too limiting for certain usecases. Instead add the ability to send down raw JSON messages that are opaque to Tailscale but provide the applications to define them however they wish. Also update accessors to use the new values.

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

Joe Tsai	9af27ba829	cmd/cloner: mangle "go:generate" in cloner.go The "go generate" command blindly looks for "//go:generate" anywhere in the file regardless of whether it is truly a comment.

julianknodt	0f18801716	cmd/cloner: support maps with clone ptrs In order to clone DERPMaps, it was necessary to extend the cloner so that it supports nested pointers inside of maps which are also cloneable.

Josh Bleecher Snyder	2352690bde	cmd/cloner: ensure cloner gets re-run when structs change If you change a struct and don't re-run cloner, your Cloner method might be inaccurate, leading to bad things. To prevent this, write out the struct as it is at the moment that cloner is caller, and attempt a conversion from that type. If the struct gets changed in any way, this conversion will fail. This will yield false positives: If you change a non-pointer field, you will be forced to re-run cloner, even though the actual generated code won't change. I think this is an acceptable cost: It is a minor annoyance, which will prevent real bugs. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
