	Previously, the import statement collision detection mechanism aborted go-marshal whenever it detected two imports in any package that has the same local name. Consider this trivial package, defined by the the following two source files: file1.go: package example import ( path/a/to/foo ) ... file2.go: package example import ( another/package/with/final/component/foo ) ... Go-marshal previously couldn't handle generating code for the the above package, even if none of the types marked for marshalling used either of the imported foo packages. This turns out to be too restrictive as we run into this a lot in practice. Examples include "encoding/binary" vs "gvisor/pkg/binary/binary", and "sync" vs "gvisor/pkg/sync/sync". This change allows go-marshal to proceed with marshalling, and only abort if the code generated by go-marshal references any such ambiguous import names. PiperOrigin-RevId: 304131190
2020-03-31	Implement automated marshalling for slices of Marshallable types.	Rahat Mahmood
	PiperOrigin-RevId: 304119255
2020-03-25	Fix go_marshal Example name.	Adin Scannell
	There is a canonical naming convention for Examples, which are checked by analyzers. This must be fixed since adding exceptions for generated code will be more challenging.
2020-02-27	Implement automated marshalling for newtypes on arrays.	Rahat Mahmood
	PiperOrigin-RevId: 297693838
2020-02-20	Implement automated marshalling for newtypes on primitives.	gVisor bot
	PiperOrigin-RevId: 296322954
2020-02-20	Remove bytes read/written from marshal.Marshallable API.	gVisor bot
	Users of the API only care about whether the copy in/out succeeds in their entirety, which is already signalled by the returned error. PiperOrigin-RevId: 296297843
2020-02-19	Handle situations where go-marshal generates an empty test file.	gVisor bot
	This can happen due to conditional compilation, where a subset of the source files contain no marshallable types. go-marshal is still required to write an output file in these cases, since bazel defines the output package before calling go-marshal. PiperOrigin-RevId: 296074321
2020-02-18	go-marshal: Stop complaining about files with no +marshal types.	gVisor bot
	Since we tag entire packages as marshallable, due to conditional compiling for different architectures we can end up with sets of source files that don't contain any marshallable types. It's safe to silently ignore this scenario. PiperOrigin-RevId: 295831871
2020-02-15	Ensure Marshallable.SizeBytes() always works on a typed nil pointer.	gVisor bot
	This lets go-marshal replace various calls to binary.Size() throughout the sentry without requiring concrete objects. PiperOrigin-RevId: 295299965
2020-02-14	Generate implementation of io.WriterTo via go-marshal.	gVisor bot
	PiperOrigin-RevId: 295269654
2020-02-14	Add a minimal binary target for escape analysis on go-marshal.	gVisor bot
	Note that this is not an automated test. PiperOrigin-RevId: 295238672
2020-02-14	Fix various issues related to enabling go-marshal.	gVisor bot
	- Add missing build tags to files in the abi package. - Add the marshal package as a sentry dependency, allowed by deps_test. - Fix an issue with our top-level go_library BUILD rule, which incorrectly shadows the variable containing the input set of source files. This caused the expansion for the go_marshal clause to silently omit input files. - Fix formatting when copying build tags to gomarshal-generated files. - Fix a bug with import statement collision detection in go-marshal. PiperOrigin-RevId: 295112284
2020-02-13	Ensure the marshalled object doesn't escape.	gVisor bot
	Add new Marshallable interface methods CopyIn/CopyOut, which can be directly called on the marshalled object, avoiding an interface indirection. Such indirections are problematic because they always cause the marshalled object to escape. PiperOrigin-RevId: 295028010
2020-02-04	Automatically propagate tags for stateify and marshal.	Adin Scannell
	Note that files will need to be appropriately segmented in order for the mechanism to work, in suffixes implying special tags. This only needs to happen for cases where marshal or state structures are defined, which should be rare and mostly architecture specific. PiperOrigin-RevId: 293231579
2020-01-27	Update package locations.	Adin Scannell
	Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289
2020-01-27	Fix licenses.	Adin Scannell
	The preferred Copyright holder is "The gVisor Authors". PiperOrigin-RevId: 291786657
2020-01-27	Standardize on tools directory.	Adin Scannell
	PiperOrigin-RevId: 291745021
2019-11-21	Import and structure cleanup.	Adin Scannell
	PiperOrigin-RevId: 281795269
2019-09-12	Remove go_test from go_stateify and go_marshal	Michael Pratt
	They are no-ops, so the standard rule works fine. PiperOrigin-RevId: 268776264
2019-09-09	go_marshal: Implement automatic generation of ABI marshalling code.	Rahat Mahmood
	This CL implements go_marshal, a code generation utility for automatically serializing and deserializing ABI structs. The go_marshal tool automatically generates implementations of the new marshal interface. Unlike binary.Marshal/Unmarshal, the generated interface implementations use no runtime reflection, and translates to a single memcpy for most structs. See go_marshal/README.md for details.
