2022-09-06os: delete unused errClosedAndy Pan
errClosed was introduced by CL 163058 and was supposed to be removed by CL 243906, but somehow it was left out, now we should get it deleted.

2020-04-25os, net: define and use os.ErrDeadlineExceededIan Lance Taylor
If an I/O operation fails because a deadline was exceeded, return os.ErrDeadlineExceeded. We used to return poll.ErrTimeout, an internal error, and told users to check the Timeout method. However, there are other errors with a Timeout method that returns true, notably syscall.ETIMEDOUT which is returned for a keep-alive timeout. Checking errors.Is(err, os.ErrDeadlineExceeded) should permit code to reliably tell why it failed. This change does not affect the handling of net.Dialer.Deadline, nor does it change the handling of net.DialContext when the context deadline is exceeded. Those cases continue to return an error reported as "i/o timeout" for which Timeout is true, but that error is not os.ErrDeadlineExceeded.

2019-08-02os: don't consult Is methods on non-syscall error typesDamien Neil
CL #163058 moves interpretation of platform-specific errors to the syscall package. Package syscall errors implement an Is method which os.IsPermission etc. consult. This results in an unintended semantic change to the os package predicate functions: The following program now prints 'true' where it used to print 'false': package main import "os" type myError struct{ error } func (e myError) Is(target error) bool { return target == os.ErrPermission } func main() { println(os.IsPermission(myError{})) } Change the os package error predicate functions to only examine syscall errors, avoiding this semantic change. This CL does retain one minor semantic change: On Plan9, os.IsPermission used to return true for any error with text containing the string "permission denied". It now only returns true for a syscall.ErrorString containing that text.

2019-08-02all: remove os.ErrTimeoutDamien Neil
It is unclear whether the current definition of os.IsTimeout is desirable or not. Drop ErrTimeout for now so we can consider adding it (or some other error) in a future release with a corrected definition.

2019-08-01all: remove os.ErrTemporaryDamien Neil
As discussed in https://github.com/golang/go/issues/32463#issuecomment-506833421 the classification of deadline-based timeouts as "temporary" errors is a historical accident. I/O timeouts used to be duration-based, so they really were temporary--retrying a timed-out operation could succeed. Now that they're deadline-based, timeouts aren't temporary unless you reset the deadline. Drop ErrTemporary from Go 1.13, since its definition is wrong. We'll consider putting it back in Go 1.14 with a clear definition and deprecate net.OpError.Temporary.

2019-05-04all: add Unwrap and Is methods to various error typesDamien Neil
Add Unwrap methods to types which wrap an underlying error: "encodinc/csv".ParseError "encoding/json".MarshalerError "net/http".transportReadFromServerError "net".OpError "net".DNSConfigError "net/url".Error "os/exec".Error "signal/internal/pty".PtyError "text/template".ExecError Add os.ErrTemporary. A case could be made for putting this error value in package net, since no exported error types in package os include a Temporary method. However, syscall errors returned from the os package do include this method. Add Is methods to error types with a Timeout or Temporary method, making errors.Is(err, os.Err{Timeout,Temporary}) equivalent to testing the corresponding method: "context".DeadlineExceeded "internal/poll".TimeoutError "net".adrinfoErrno "net".OpError "net".DNSError "net/http".httpError "net/http".tlsHandshakeTimeoutError "net/pipe".timeoutError "net/url".Error Updates #30322 Updates #29934 Change-Id: I409fb20c072ea39116ebfb8c7534d493483870dc Reviewed-on: https://go-review.googlesource.com/c/go/+/170037 Run-TryBot: Damien Neil <dneil@google.com> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Marcel van Lohuizen <mpvl@golang.org>

As proposed in Issue #29934, update errors produced by the os package to work with errors.Is sentinel tests. For example, errors.Is(err, os.ErrPermission) is equivalent to os.IsPermission(err) with added unwrapping support. Move the definition for os.ErrPermission and others into the syscall package. Add an Is method to syscall.Errno and others. Add an Unwrap method to os.PathError and others.
