* net: do not use sendfile on iOSCherry Mui2021-12-011-1/+1
| | | | | | | | | | | | | | | | | Apparently, on the iOS builder sendfile causes a SIGSYS signal (instead of returning ENOSYS). Disabling it for now so we can make progress on iOS. We can revisit if sendfile is actually broken on iOS and whether it is beneficial. Updates #49616.

* all: go fix -fix=buildtag std cmd (except for bootstrap deps, vendor)Russ Cox2021-10-281-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | When these packages are released as part of Go 1.18, Go 1.16 will no longer be supported, so we can remove the +build tags in these files. Ran go fix -fix=buildtag std cmd and then reverted the bootstrapDirs as defined in src/cmd/dist/buildtool.go, which need to continue to build with Go 1.4 for now. Also reverted src/vendor and src/cmd/vendor, which will need to be updated in their own repos first. Manual changes in runtime/pprof/mprof_test.go to adjust line numbers. For #41184.

* net: return poll.SendFile error from sendFileIan Lance Taylor2019-03-011-2/+2
| | | | | | | | | | | | We were accidentally ignoring any error returned by poll.SendFile. Noticed by reading the code. It could only change behavior if the sendfile system call both wrote some bytes and returned an error.

| | | | | | | | | | | | | | Use SyscallConn to avoid calling the Fd method in sendFile on Unix systems, since Fd has the side effect of putting the descriptor into blocking mode.

| | | | | | | | | | | | | | On dragonfly, freebsd and solaris the sendfile syscall does not update the read position of the source fd.
