lsof is used to inspect the open file desciptors in exec_test.go. In order to limit the output of lsof to the tested process, the tests use lsof with the -p option, but the version of lsof in android seems to ignore it. This change adds a post-processing step to filter out irrelevant entries. Fixes golang/go#10206.

Package socktest provides utilities for socket testing. This package allows test cases in the net package to simulate complicated network conditions such as that a destination address is resolvable/discoverable but is not routable/reachable at network layer. Those conditions are required for testing functionality of timeout, multiple address families.

Previously the extra m needed for cgo callbacks was created on the first callback. This works for cgo, however the cgocallback mechanism is also borrowed by badsignal which can run before any cgo calls are made. Now we initialize the extra M at runtime startup before any signal handlers are registered, so badsignal cannot be called until the extra M is ready. Updates #10207.

There are calls to stdcall when the GC thinks the world is stopped and stdcall write a *g for the CPU profiler. This produces a write barrier but the GC is not prepared to deal with write barriers when it thinks the world is stopped. Since the g is on allg it does not need a write barrier to keep it alive so eliminate the write barrier.

windows/386 also wants underscore prefix for external names. This CL is in preparation of external linking support. Change-Id: I2d2ea233f976aab3f356f9b508cdd246d5013e2d Signed-off-by:

Shenghou Ma authored
When external linking, we must link to implib provided by mingw, so we must use properly decorated names for stdcalls. Because the feature is only used in the runtime, I've designed a new decoration scheme so that we can use the same decorated name for both 386 and amd64. A stdcall function named FooEx from bar16.dll which takes 3 parameters will be imported like this: //go:cgo_import_dynamic runtime._FooEx FooEx%3 "bar16.dll" Depending on the size of uintptr, the linker will later transform it to _FooEx@12 or _FooEx@24. This is in prepration for the next CL that adds external linking support for windows/386. Change-Id: I2d2ea233f976aab3f356f9b508cdd246d5013e2c Signed-off-by:

The debug/dwarf and encoding/asn1 examples were added in 2009, a few months before Go added implicit semicolons, and never updated. The go/ast node types have always been named just "Expr", "Stmt", and "Decl", so the comments about "ExprNode", "StmtNode", and "DeclNode" were likely just mistaken because the interface tag methods are "exprNode", "stmtNode", and "declNode", respectively.

Instead of reimplementing chained hash tables, just use maps. Use bool instead of uint8 for variables only set to 0 or 1. Fix parsing of `import foo "foo" // indirect` lines. Previously, this was treated as an import of package path `"foo" // indirect`, which could result in the cycle-detection code failing to detect a cycle because it would be treated as a separate package from `"foo"`. Also, since there are theoretically multiple quoted forms for a package path, use strconv.Unquote to normalize them. Side benefit: Unquote will complain if any trailing comments sneak back in. Aside: For most Go archives, Go package data is only present in the __.PKGDEF member, but unless -u is used, ldpkg is only called on the _go_.6 member. Consequently, importcycles is a no-op when -u isn't used as it has no package data to inspect.

The imageutil.DrawYCbCr function lives in an internal package because it is needed by both the image/draw and image/jpeg packages, but it doesn't seem right for one of those two to depend on the other. It could eventually go into the image package, but that would require committing to an API for the rest of Go 1.x.

Previously, running 'go get' with a local path would correctly download the package but fail to install it. This is because a sticky error - resulting from discovering that the package needed to be downloaded - was still around. Theoretically, such sticky errors would be cleared but they weren't because the map tracking these errors were indexed with the correct canonical import path of the package (e.g. "ex.com/x/pkg") whereas the clearing was done with the local path (e.g. "./pkg".) Always use the canonical import path. Fixes #9767 Change-Id: Ia0e8a51ac591d4c833d11285da5b767ef7ed8ad2 Reviewed-on: https://go-review.googlesource.com/6266Reviewed-by:
