* all: remove os.ErrTimeoutDamien Neil2019-08-021-9/+0
| | | | | | | | | | | | | | 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.

* all: remove os.ErrTemporaryDamien Neil2019-08-011-2/+0
| | | | | | | | | | | | | | | | | | | | 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.

* all: add Unwrap and Is methods to various error typesDamien Neil2019-05-041-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* net: set DNSError.IsTemporary from addrinfoErrno errorsMichael Vogt2019-05-011-3/+9
| | | | | | | | | | | | Today it is not possible (AFAICT) to detect if a DNSError if of type EAI_AGAIN, i.e. if it is something temporary that should be retried. This information is available inside addrinfoErrno but when the DNSError is created this information is lost. This PR fixes this so that the addinfoErrno.Temporary information is added to DNSError as well. With that a user who gets a DNSError can check now is its a temporary error (for errors that resulted from a addrinfoErrno this is EAI_AGAIN).

* net: make cgo resolver work more accurately with network parameterEugene Kalinin2018-10-251-16/+21
| | | | | | | | | | | | | | | | | | | Unlike the go resolver, the existing cgo resolver exchanges both DNS A and AAAA RR queries unconditionally and causes unreasonable connection setup latencies to applications using the cgo resolver. This change adds new argument (`network`) in all functions through the series of calls: from Resolver.internetAddrList to cgoLookupIPCNAME. Benefit: no redundant DNS calls if certain IP version is used IPv4/IPv6 (no `AAAA` DNS requests if used tcp4, udp4, ip4 network. And vice versa: no `A` DNS requests if used tcp6, udp6, ip6 network) Fixes #25947 Change-Id: I39edbd726d82d6133fdada4d06cd90d401e7e669 Reviewed-on: https://go-review.googlesource.com/c/120215 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>

* net: make LookupPort and lookupProtocol work on naclBrad Fitzpatrick2016-09-111-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Also, flesh out the baked-in /etc/services table for LookupPort a bit. This services map moves from a unix-specific file to a portable file where nacl can use it. Also, remove the duplicated entries in the protocol map in different cases, and just canonicalize the input before looking in the map. Now it handles any case, including MiXeD cAse. In the process, add a test that service names for LookupPort are case insensitive. They were on Windows, but not cgo. Now there's a test and they're case insensitive in all 3+ paths. Maybe it breaks plan9. We'll see.

* net: force LookupAddr results to be rooted DNS paths when using cgoRuss Cox2015-08-191-0/+5
| | | | | | | | | | | | | | | | | | | | Go 1.4 and before have always returned DNS names with a trailing dot for reverse lookups, as they do for basically all other routines returning DNS names. Go 1.4 and before always implemented LookupAddr using pure Go (not C library calls). Go 1.5 added the ability to make a C library call to implement LookupAddr. Unfortunately the C library call returns a DNS name without a trailing dot (an unrooted name), meaning that if turn off cgo during make.bash then you still get the rooted name but with cgo on you get an unrooted name. The unrooted name is inconsistent with the pure Go implementation and with all previous Go releases, so change it to a rooted name. Fixes #12189.
