Issues fixed: * Could not handle quantity of seconds greater than 1<<31 on 32bit machines since strconv.ParseInt did not treat integers as 64b. * Did not handle negative timestamps properly if nanoseconds were used. Note that "-123.456" should result in a call to time.Unix(-123, -456000000). * Incorrectly allowed a '-' right after the '.' (e.g., -123.-456) * Did not detect invalid input after the truncation point (e.g., 123.123456789badbadbad). Note that negative timestamps are allowed by PAX, but are not guaranteed to be portable. See the relevant specification: <<< If pax encounters a file with a negative timestamp in copy or write mode, it can reject the file, substitute a non-negative timestamp, or generate a non-portable timestamp with a leading '-'. >>> Since the previous behavior already partially supported negative timestamps, we are bound by Go's compatibility rules to keep support for them. However, we should at least make sure we handle them properly.

oneNewExtraM creates a spare M and G for use with cgo callbacks. The G doesn't run right away, but goes directly into syscall status. For the garbage collector, it's marked as "scan valid" and not on the rescan list, but I forgot to also mark it as "scan done". As a result, gcMarkRootCheck thinks that the goroutine hasn't been scanned and panics. This only affects GODEBUG=gccheckmark=1 mode, since we otherwise skip the gcMarkRootCheck. Fixes #17473.

Updating the heap profile stats is one of the most expensive parts of mark termination other than stack rescanning, but there's really no need to do this with the world stopped. Move it to right after we've started the world back up. This creates a *very* small window where allocations from the next cycle can slip into the profile, but the exact point where mark termination happens is so non-deterministic already that a slight reordering here is unimportant.

The only reason these flushes are still necessary at all is that gcmarknewobject doesn't flush its gcWork stats like it's supposed to. By changing gcmarknewobject to follow the standard protocol, the flushes become completely unnecessary because mark 2 ensures caches are flushed (and stay flushed) before we ever enter mark termination. In the garbage benchmark, this takes roughly 50 µs, which is surprisingly long for doing nothing. We still double-check after draining that they are in fact empty.

The pointer checking code needs to know the exact type of the parameter expected by the C function, so that it can use a type assertion to convert the empty interface returned by cgoCheckPointer to the correct type. Previously this was done by using a type conversion, but that meant that the code accepted arguments that were convertible to the parameter type, rather than arguments that were assignable as in a normal function call. In other words, some code that should not have passed type checking was accepted. This CL changes cgo to always use a function literal for pointer checking. Now the argument is passed to the function literal, which has the correct argument type, so type checking is performed just as for a function call as it should be. Since we now always use a function literal, simplify the checking code to run as a statement by itself. It now no longer needs to return a value, and we no longer need a type assertion. This does have the cost of introducing another function call into any call to a C function that requires pointer checking, but the cost of the additional call should be minimal compared to the cost of pointer checking. Fixes #16591.

Instead, use runtime.throw, which will crash the program directly. In general throw is reserved for when the runtime detects truly serious, unrecoverable problems. This problem is certainly serious, and, without a significant performance hit, is unrecoverable. Fixes #13879.

This CL makes NewRequest set Body nil for known-zero bodies, and makes the http1 Transport not peek-Read a byte to determine whether there's a body. Background: Many fields of the Request struct have different meanings for whether they're outgoing (via the Transport) or incoming (via the Server). For outgoing requests, ContentLength and Body are documented as: // Body is the request's body. // // For client requests a nil body means the request has no // body, such as a GET request. The HTTP Client's Transport // is responsible for calling the Close method. Body io.ReadCloser // ContentLength records the length of the associated content. // The value -1 indicates that the length is unknown. // Values >= 0 indicate that the given number of bytes may // be read from Body. // For client requests, a value of 0 with a non-nil Body is // also treated as unknown. ContentLength int64 Because of the ambiguity of what ContentLength==0 means, the http1 and http2 Transports previously Read the first byte of a non-nil Body when the ContentLength was 0 to determine whether there was an actual body (with a non-zero length) and ContentLength just wasn't populated, or it was actually empty. That byte-sniff has been problematic and gross (see #17480, #17071) and was removed for http2 in a previous commit. That means, however, that users doing: req, _ := http.NewRequest("POST", url, strings.NewReader("")) ... would not send a Content-Length header in their http2 request, because the size of the reader (even though it was known, being one of the three common recognized types from NewRequest) was zero, and so the HTTP Transport thought it was simply unset. To signal explicitly-zero vs unset-zero, this CL changes NewRequest to signal explicitly-zero by setting the Body to nil, instead of the strings.NewReader("") or other zero-byte reader. This CL also removes the byte sniff from the http1 Transport, like https://golang.org/cl/31326 did for http2.

Many users quote literals in regular expressions just in case. No need to allocate then.

Implements Float.Scan which satisfies fmt.Scanner interface. Also enforces docs' interface implementation claims with compile time type assertions, that is: + Float always implements fmt.Formatter and fmt.Scanner + Int always implements fmt.Formatter and fmt.Scanner + Rat always implements fmt.Formatter which will ensure that the API claims are strictly matched. Also note that Float.Scan doesn't handle ±Inf. Fixes #17391 Change-Id: I3d3dfbe7f602066975c7a7794fe25b4c645440ce Reviewed-on: https://go-review.googlesource.com/30723Reviewed-by:

For example, testing the current directory: $ go test -run XXX testing: warning: no tests to run PASS ok testing 0.013s $ And in a summary: $ go test -run XXX testing ok testing 0.013s [no tests to run] $ These make it easy to spot when the -run regexp hasn't matched anything or there are no tests. Previously the message was printed in the "current directory" case when there were no tests at all, but not for no matches, and either way was not surfaced in the directory list summary form. Fixes #15211. Change-Id: I1c82a423d6bd429fb991c9ca964c9d26c96fd3c5 Reviewed-on: https://go-review.googlesource.com/22341Reviewed-by:
