TestOnlyWriteTimeout assumes wrongly that: - the Accept method of trackLastConnListener is called only once - the shared variable conn never becomes nil and crashes on some circumstances.

The only new Types that the backend introduces are pointers to Types generated by the frontend. Usually, when we generate a *T, we cache the resulting Type in T, to avoid recreating it later. However, that caching is not concurrency safe. Rather than add mutexes, this CL disables that caching before starting the backend. The backend generates few enough new *Ts that the performance impact of this is small, particularly if we pre-create some commonly used *Ts.

I broke FreeBSD 9 in https://golang.org/cl/38426 by using Pipe2. We still want to support FreeBSD 9 for one last release (Go 1.9 will be the last), and FreeBSD 9 doesn't have Pipe2. So this still uses Pipe2, but falls back to Pipe on error.

During AllocFrame, we drop unused variables from Curfn.Func.Dcl, but there might still be OpVarFoo instructions that reference those variables. This wasn't a problem though because gvardefx used to emit ANOP for unused variables instead of AVARFOO. As an easy fix, if we see OpVarFoo (or OpKeepAlive) referencing an unused variable, we can ignore it. Fixes #19632.

The chanrecv funcs don't use it at all. The chansend ones do, but the element type is now part of the hchan struct, which is already a parameter. hchan can be nil in chansend when sending to a nil channel, so when instrumenting we must copy to the stack to be able to read the channel type. name old time/op new time/op delta ChanUncontended 6.42µs ± 1% 6.22µs ± 0% -3.06% (p=0.000 n=19+18) Initially found by github.com/mvdan/unparam.

The old implementation of Jar made the assumption that the host names in the URLs given to SetCookies() and Cookies() methods are well-formed. This is not an unreasonable assumption as malformed host names do not trigger calls to SetCookies or Cookies (at least not from net/http) as the HTTP request themselves are not executed. But there can be other invocations of these methods and at least on Linux it was possible to make DNS lookup to domain names with two trailing dots (see issue #7122). This is an old bug and this CL revives an old change (see https://codereview.appspot.com/52100043) to fix the issue. The discussion around 52100043 focused on the interplay between the jar and the public suffix list and who is responsible for which type if domain name canonicalization. The new bug report in issue #19384 used a nil public suffix list which demonstrates that the package cookiejar alone exhibits this problem and any solution cannot be fully delegated to the implementation of the used PublicSuffixList: Package cookiejar itself needs to protect against host names of the form ".." which triggered an out-of-bounds error. This CL does not address the issue of host name canonicalization and the question who is responsible for it. This CL just prevents the out-of-bounds error: It is a very conservative change, i.e. one might still set and retrieve cookies for host names like "weird.stuf...". Several more test cases document how the current code works. Fixes #19384.

Prior to this CL, the function's position was used. The dottype Node's position is clearly better. I'm not thrilled about introducing a reference to lineno in the middle of SSA construction; I will have to remove it later. My immediate goal is stability and correctness of positions, though, since that aids refactoring, so this is an improvement. An example from package io: func (t *multiWriter) WriteString(s string) (n int, err error) { var p []byte // lazily initialized if/when needed for _, w := range t.writers { if sw, ok := w.(stringWriter); ok { n, err = sw.WriteString(s) The w.(stringWriter) type assertion includes loading the address of static type data for stringWriter: LEAQ type."".stringWriter(SB), R10 Prior to this CL, this instruction was given the line number of the function declaration. After this CL, this instruction is given the line number of the type assertion itself.

This paragraph has been added, as the notion was missing from the documentation. If a value is passed to Encode and the type is not a struct (or pointer to struct, etc.), for simplicity of processing it is represented as a struct of one field. The only visible effect of this is to encode a zero byte after the value, just as after the last field of an encoded struct, so that the decode algorithm knows when the top-level value is complete.

Previously, we handled recursive interfaces by deferring typechecking of interface methods, while eagerly expanding interface embeddings.
