netpoll is perhaps one of the most confusing uses of G lists currently since it passes around many lists as bare *g values right now. Switching to gList makes it much clearer what's an individual g and what's a list.

There are two manually managed G dequeues. Abstract these both into a shared gQueue type. This also introduces a gList type, which we'll use to replace several manually-managed G lists in follow-up CLs. This makes the code more readable and maintainable. gcFlushBgCredit in particular becomes much easier to follow. It also makes it easier to introduce more G queues in the future. Finally, the gList type clearly distinguishes between lists of Gs and individual Gs; currently both are represented by a *g, which can easily lead to confusion and bugs.

TMLL, LGDR and LDGR have all been added to the Go assembler previously, so we don't need to encode them using WORD and BYTE directives anymore. This is purely a cosmetic change, it does not change the contents of any object files.

Previously Scanner would allow float literals like "1.5e" and "1e+" that weren't actually valid Go float literals, and also not valid when passed to ParseFloat. This commit fixes that behaviour to match the documentation ("recognizes all literals as defined by the Go language specification"), and Scanner emits an error in these cases.

Avoid using package specific variables when there is a one to one correspondance to cpu feature support exported by internal/cpu. This makes it clearer which cpu feature is referenced. Another advantage is that internal/cpu variables are padded to avoid false sharing and memory and cache usage is shared by multiple packages.

CL 52430 added logic to skip the testZoneAbbr test in locales where the timezone does not have a three-letter name, because the following line Parse(RFC1123, t1.Format(RFC1123)) failed for timezones with only numeric names (like -07). Since Go 1.11, Parse supports the parsing of timezones with numeric names (this was implemented in CL 98157), so we can now run the test unconditionally.

FLD1 pushes +1.0 to the 387 register stack, and FLDZ pushes +0.0 to the 387 regiser stack. They can be used to simplify MOVSSconst/MOVSDconst when the constant is +0.0, -0.0, +1.0, -1.0. The size of the go executable reduces about 62KB and the total size of pkg/linux_386 reduces about 7KB with this optimization.

Issues #10043, #15405, and #22660 appear to have been fixed, and whatever tests I could run locally do succeed, so remove the skips. Issue #7237 was closed in favor of #17906, so update its skip line. Issue #7634 was closed as it had not appeared for over three years. Re-enable it for now. An issue should be open if the test starts being skipped again.

To report the capacity of the underlying buffer. The method mirrors bytes.Buffer.Cap. The method can be useful to know whether or not calling write or grow methods will result in an allocation, or to know how much memory has been allocated so far. Fixes #26269.

This lets us simplify the code considerably. For example, unquoting the tag is no longer necessary, and we can get the field name with a single method call. While at it, fix a typechecking error in testdata/structtag.go, which hadn't been caught since vet still skips past go/types errors in most cases. Using go/types will also let us expand the structtag check more easily if we want to, for example to allow it to check for duplicates in embedded fields. Finally, update one of the test cases to check for regressions when we output invalid tag strings. We also checked that these two changes to testdata/structtag.go didn't fail with the old structtag check. For #25593.

Port CL 120295 from golang.org/x/sys/unix to the syscall package. The ustat syscall has been deprecated on Linux for a long time and the upcoming glibc 2.28 will remove ustat.h and it can no longer be used to to generate the Ustat_t wrapper type. Since Linux still provides the syscall, let's not break this functionality and add a private copy of struct ustat so Ustat_t can still be generated.

Combined appends lead to fewer machine code and faster performance. Some may even say that it makes code more readable.

These are all errors given by module-aware cmd/go, so they must end with a newline. It looks like they were omitted by mistake. Fixes #27081.

It was a bug to find that commit in the Masterminds/semver repo. It's not part of the main repo but only part of an unmerged pull request. The code was updated to try not to look at unmerged pull requests, but the test was not. Worse, whether the code succeeds at not looking at unmerged pull requests apparently depends on the git version. Sigh. Fixes #26754. Fixes #27043.

In GOPATH mode the rule has always been that 'go run x.go' can import whatever the package in x.go's directory would be able to import. Apply the same rule here. The bad import path was triggering other mysterious errors during 'go run' in other circumstances. Setting it correctly fixes those too. Fixes #26046. Fixes #27022.

This is an important security problem so we shouldn't disable the test. The second half was failing on case-sensitive file systems but the first half is still good. Fixes #22983.

If you run go get -u github.com/rsc/foo/bar... then the go get command has always worked hard to make sure that it applies the wildcard after downloading rsc/foo. (If it applied the wildcard only before downloading rsc/foo, it would match nothing if you had an empty GOPATH before, and you'd still have an empty afterward, which is clearly useless.) The goal has always been that if you run the same go get command twice, the second command doesn't find anything new to do. CL 19892 worked around an "internal error" failure but broke the rule about the first command doing everything the second command would. Suppose you had github.com/rsc/foo already, with just github.com/rsc/foo/bar, and you run go get -u github.com/rsc/... The wildcard first matches github.com/rsc/foo/bar, but suppose updating the repo pulls down github.com/rsc/foo/baz, which in turn depends on the non-existent package github.com/rsc/quux. We need to reevaluate the wildcard after the download. The new pattern match refactoring makes this easier and happened to have corrected the behavior, but we missed a long test that expected the old behavior. Fix that long test.

If we're looking for a module for a/b/c/d/e, we check for a module named a/b/c/d/e, then a/b/c/d, then a/b/c, then a/b, then a. If we know the source repo for a/b/c and that fails, we should report that error instead of continuing the loop: a/b and a are useless, and the error from a/b/c contains important information. The errors are now a bit more verbose than I'd like but they will suffice for Go 1.11. $ go get github.com/bradfitz/private/sonos go get github.com/bradfitz/private/sonos: git ls-remote -q origin in /Users/rsc/pkg/mod/cache/vcs/61e3c76780847e514802ec6af8f940f641c6017f711444f05c59cb17ac46d456: exit status 128: remote: Repository not found. fatal: repository 'https://github.com/bradfitz/private/' not found $ go list launchpad.net/gocheck can't load package: package launchpad.net/gocheck: unknown import path "launchpad.net/gocheck": bzr branch --use-existing-dir https://launchpad.net/~niemeyer/gocheck/trunk . in /Users/rsc/pkg/mod/cache/vcs/f46ce2ae80d31f9b0a29099baa203e3b6d269dace4e5357a2cf74bd109e13339: exec: "bzr": executable file not found in $PATH $ Fixes #26885.

"go mod fix" does work already done by nearly every other go command. It was also confusing why we had both "go mod fix" and "go mod tidy". Delete "go mod fix". The main reason we kept "go mod fix" this long was for the discussion of automatic go.mod updates in its documentation, which is now moved into a new "go help go.mod". Fixes #26831.

The proxy protocol was simplified to only send (and only receive) the Path and Version fields in the JSON blob, not Name and Short. (Those make sense when querying a VCS repo directly, but not when talking about extracted modules.) So don't expect them in the test. Fixes #27042.
