go.mod file exists in a subdirectory for that version
Previous versions of the 'go' command would reject a pseudo-version
passed to 'go get' if that pseudo-version had a mismatched major
version and lacked a "+incompatible" suffix. However, they would
erroneously accept a version *with* a "+incompatible" suffix even if
the repo contained a vN/go.mod file for the same major version, and
would generate a "+incompatible" pseudo-version or version if the user
requested a tag, branch, or commit hash.
This change uniformly rejects "vN.…" without "+incompatible", and also
avoids resolving to "vN.…+incompatible", when vN/go.mod exists.
To maintain compatibility with existing go.mod files, it still accepts
"vN.…+incompatible" if the version is requested explicitly as such
and the repo root lacks a go.mod file.

canonical versions
Since at least CL 121857, the conversion logic in
(*modfetch).codeRepo.Stat has had a short-circuit to use the version
requested by the caller if it successfully resolves and is already
canonical.
However, we should not use that version if it refers to a branch
instead of a tag, because branches (unlike tags) usually do not refer
to a single, stable release: a branch named "v1.0.0" may be for the
development of the v1.0.0 release, or for the development of patches
based on v1.0.0, but only one commit (perhaps at the end of that
branch — but possibly not even written yet!) can be that specific
version.
We already have some logic to prefer tags that are semver-equivalent
to the version requested by the caller. That more general case
suffices for exact equality too — so we can eliminate the
special-case, fixing the bug and (happily!) also somewhat simplifying
the code.

When a module author retracts a version, the go command should act as
if it doesn't exist unless it's specifically requested.
When converting a revision to a version, we should ignore tags for
retracted versions. For example, if the tag v1.0.0 is retracted, and
branch B points to the same revision, we should convert B to a
pseudo-version, not v1.0.0. Similarly, if B points to a commit after
v1.0.0, we should not use v1.0.0 as the base; we can use an earlier
non-retracted tag or no base.

We know of at least one module (github.com/stripe/stripe-go) that has
a run of +incompatible versions, followed by a run of versions with
go.mod files, followed by another run of +incompatible versions.
We want the heuristics for showing +incompatible versions to reflect
the authors' current intent, and it seems clear that the current
intent of the authors of that module is for users of the unversioned
import path to still be on +incompatible versions.
To respect that intent, we need to keep checking for +incompatible
versions even after we have seen a lower major version with an
explicit go.mod file.
However, we still don't want to download every single version of the
module to check it. A given major version should have a consistent,
canonical import path, so the path (as inferred by the presence or
absence of a go.mod file) should be the same for every release across
that major version.
To avoid unnecessary overhead — and to allow module authors to correct
accidental changes to a major version's import path — we check only
the most recent release of each major version. If a release
accidentally changes the import path in either direction (by deleting
or adding a go.mod file), it can be corrected by issuing a single
subsequent release of that major version to restore the correct path.
I manually verified that, with this change,
github.com/stripe/stripe-go@latest reverts to v68.7.0+incompatible
as it was in Go 1.13.
The other regression tests for #34165 continue to pass.

The 'go' command normally requires the 'go.mod' files for replacement
modules to have a major version compatible with the module they are
replacing.
However, prior to CL 206761, the 'go' command erroneously allowed
unversioned paths (which imply major version 0 or 1) to replace
'gopkg.in' paths with any major-version suffix.
An analysis of proxy.golang.org suggests that these replacements,
while uncommon, are not unheard-of. Rather than breaking the modules
that rely on them, we will continue to allow the erroneous replacement
paths for this particular pairing.

codeRepo.Versions previously checked every possible +incompatible
version for a 'go.mod' file. That is wasteful and counterproductive.
It is wasteful because typically, a project will adopt modules at some
major version, after which they will (be required to) use semantic
import paths for future major versions.
It is counterproductive because it causes an accidental
'+incompatible' tag to exist, and no compatible tag can have higher
semantic precedence.
This change prunes out some of the +incompatible versions in
codeRepo.Versions, eliminating the “wasteful” part but not all of the
“counterproductive” part: the extraneous versions can still be fetched
explicitly, and proxies may include them in the @v/list endpoint.

This change integrates changes made to x/mod packages into our internal
copies of those packages.
This is the first step of a bidirectional synchronization. A follow-up
change will copy changes made to the internal packages after x/mod was
forked. After that, we can vendor x/mod, update imports, and delete
the internal copies.
The following packages are affected:
* internal/module
* internal/semver (no change)
* internal/sumweb (renamed to internal/sumdb)
* internal/dirhash
* internal/note
* internal/tlog
Several integrated changes affect other packages:
* cmd/go/internal/module.MatchPathMajor now wraps a new function,
CheckPathMajor, which returns error. MatchPathMajor returns
bool. This will avoid an incompatible change in the next step.
* module.EncodePath renamed to EscapePath, EncodeVersion to
EscapeVersion, DecodePath to UnescapePath, DecodeVersion to
UnescapeVersion.
* cmd/go/internal/sumweb moved to cmd/go/internal/sumdb and package
renamed to sumdb.
* sumdb.Client renamed to ClientOps, Conn to Client, Server to
ServerOps, Paths to ServerPaths.
* sumdb/encode.go and encode_test.go are not present in x/mod since
they are redundant with functionality in module. Both files are
deleted.
* sumdb.TestServer doesn't implement sumdb.ServerOps after changes
were were made to golang.org/x/mod/sumdb.ServerOps during the fork.
Local changes made so tests will pass. These will be copied to x/mod
in the next step.

version control
If the module path declared in the go.mod file does not match the path
we are trying to resolve, a build using that module is doomed to fail.
Since we know that the module path does not match in the underlying
repo, we also know that the requested module does not exist at the
requested version.
Therefore, we should reject that version in Stat with a “not exist”
error — sooner rather than later — so that modload.Query will continue
to check other candidate paths (for example, with a major-version
suffix added or removed).

Previously, most operations involving pseudo-versions allowed any
arbitrary combination of version string and date, and would resolve to
the underlying revision (typically a Git commit hash) as long as that
revision existed.
There are a number of problems with that approach:
• The pseudo-version participates in minimal version selection. If its
version prefix is inaccurate, the pseudo-version may appear to have
higher precedence that the releases that follow it, effectively
“pinning” the module to that commit. For release tags, module
authors are the ones who make the decision about release tagging;
they should also have control over the pseudo-version precedence
within their module.
• The commit date within the pseudo-version provides a total order
among pseudo-versions. If it is not accurate, the pseudo-version
will sort into the wrong place relative to other commits with the
same version prefix.
To address those problems, this change restricts the pseudo-versions
that the 'go' command accepts, rendering some previously
accepted-but-not-canonical versions invalid. A pseudo-version is now
valid only if all of:
1. The tag from which the pseudo-version derives points to the named
revision or one of its ancestors as reported by the underlying VCS
tool, or the pseudo-version is not derived from any tag (that is,
has a "vX.0.0-" prefix before the date string and uses the lowest
major version appropriate to the module path).
2. The date string within the pseudo-version matches the UTC timestamp
of the revision as reported by the underlying VCS tool.
3. The short name of the revision within the pseudo-version (such as a
Git hash prefix) is the same as the short name reported by the
underlying cmd/go/internal/modfetch/codehost.Repo. Specifically, if
the short name is a SHA-1 prefix, it must use the same number of
hex digits (12) as codehost.ShortenSHA1.
4. The pseudo-version includes a '+incompatible' suffix only if it is
needed for the corresponding major version, and only if the
underlying module does not have a go.mod file.
We believe that all releases of the 'go' tool have generated
pseudo-versions that meet these constraints. However, a few
pseudo-versions edited by hand or generated by third-party tools do
not. If we discover invalid-but-benign pseudo-versions in widely-used
existing dependencies, we may choose to add a whitelist for those
specific path/version combinations.
―
To work around invalid dependencies in leaf modules, users may add a
'replace' directive from the invalid version to its valid equivalent.
Note that the go command's go.mod parser automatically resolves commit
hashes found in 'replace' directives to the appropriate
pseudo-versions, so in most cases one can write something like:
replace github.com/docker/docker v1.14.0-0.20190319215453-e7b5f7dbe98c => github.com/docker/docker e7b5f7dbe98c
and then run any 'go' command (such as 'go list' or 'go mod tidy') to
resolve it to an appropriate pseudo-version. Note that the invalid
version will still be used in minimal version selection, so this use
of 'replace' directives is an incomplete workaround.
―
One of the common use cases for higher-than-tagged pseudo-versions is
for projects that do parallel development on release branches. For
example, if a project cuts a 'v1.2' release branch at v1.2.0, they may
want future commits on the main branch to show up as pre-releases for
v1.3.0 rather than for v1.2.1 — especially if v1.2.1 is already tagged
on the release branch. (On the other hand, a backport of a patch to
the v1.2 branch should not show up as a pre-release for v1.3.0.)
To address this use-case, module authors can make use of our existing
support for pseudo-versions derived from pre-release tags: if the
author adds an explicit pre-release tag (such as 'v1.3.0-devel') to
the first commit after the branch, then the pseudo-versions for that
commit and its descendents will be derived from that tag and will sort
appropriately in version selection.

Tested manually.
Before:
$ go mod init golang.org/issue/scratch
go: creating new go.mod: module golang.org/issue/scratch
$ go1.11.2 mod download github.com/rogpeppe/test2@latest
go: finding github.com/rogpeppe/test2 v0.0.11
$ find $GOPATH -name goodbye
/tmp/tmp.Y8a8UzX3zD/_gopath/pkg/mod/github.com/rogpeppe/test2@v0.0.11/tests/goodbye
$ cat $(find $GOPATH -name goodbye)
hello
After:
$ go mod init golang.org/issue/scratch
go: creating new go.mod: module golang.org/issue/scratch
$ go mod download github.com/rogpeppe/test2@latest
go: finding github.com/rogpeppe/test2 v0.0.11
$ find $GOPATH -name goodbye
$ find $GOPATH -name hello
/tmp/tmp.Zo0jhfLaRs/_gopath/pkg/mod/github.com/rogpeppe/test2@v0.0.11/tests/hello
A proper regression test would require one of:
• a new entry in the vcs-test server (feasible but tedious, and not easily updated by open-source contributors), or
• a way to set up an HTTPS proxy in a script_test, or
• a way to explicitly populate the module cache from the contents of a local repository (#28835).

temporary file
This will be used to eliminate a redundant copy in CL 145178.
(It also decouples two design points that were previously coupled: the
destination of the zip output and the program logic to write that
output.)

When we added v2.0.0+incompatible we generalized the API
enough to make it easy to also accepting these gopkg-specific
v2-unstable suffixes. Do that.
Fixes #23989.

The original pseudo-version design used versions of the form
v0.0.0-yyyymmddhhmmss-abcdef123456
These were intentionally chosen to be valid semantic versions
that sort below any explicitly-chosen semantic version (even v0.0.0),
so that they could be used before anything was tagged but after
that would essentially only be useful in replace statements
(because the max operation during MVS would always prefer
a tagged version).
Then we changed the go command to accept hashes on the
command line, so that you can say
go get github.com/my/proj@abcdef
and it will download and use v0.0.0-yyyymmddhhmmss-abcdef123456.
If you were using v1.10.1 before and this commit is just little bit
newer than that commit, calling it v0.0.0-xxx is confusing but
also harmful: the go command sees the change from v1.10.1 to
the v0.0.0 pseudoversion as a downgrade, and it downgrades other
modules in the build. In particular if some other module has
a requirement of github.com/my/proj v1.9.0 (or later), the
pseudo-version appears to be before that, so go get would
downgrade that module too. It might even remove it entirely,
if every available version needs a post-v0.0.0 version of my/proj.
This CL introduces new pseudo-version forms that can be used
to slot in after the most recent explicit tag before the commit.
If the most recent tagged commit before abcdef is v1.10.1,
then now we will use
v1.10.2-0.yyyymmddhhmmss-abcdef123456
This has the right properties for downgrades and the like,
since it is after v1.10.1 but before almost any possible
successor, such as v1.10.2, v1.10.2-1, or v1.10.2-pre.
This CL also uses those pseudo-version forms as appropriate
when mapping a hash to a pseudo-version. This fixes the
downgrade problem.
Overall, this CL reflects our growing recognition of pseudo-versions
as being like "untagged prereleases".
Issue #26150 was about documenting best practices for how
to work around this kind of accidental downgrade problem
with additional steps. Now there are no additional steps:
the problem is avoided by default.
Fixes #26150.

Repos written before the introduction of semantic import versioning
introduced tags like v2.0.0, v3.0.0, and so on, expecting that
(1) the import path would remain unchanged, and perhaps also
(2) there would be at most one copy of the package in a build.
We've always accommodated these by mapping them into the
v0/v1 version range, so that if you ran
go get k8s.io/client-go@v8.0.0
it would not complain about v8.x.x being a non-v1 version and
instead would map that version to a pseudo-version in go.mod:
require k8s.io/client-go v0.0.0-20180628043050-7d04d0e2a0a1
The pseudo-version fails to capture two important facts: first,
that this really is the v8.0.0 tag, and second, that it should be
preferred over any earlier v1 tags.
A related problem is that running "go get k8s.io/client-go"
with no version will choose the latest v1 tag (v1.5.1), which
is obsolete.
This CL introduces a new version suffix +incompatible that
indicates that the tag should be considered an (incompatible)
extension of the v1 version sequence instead of part of its
own major version with its own versioned module path.
The requirement above can now be written:
require k8s.io/client-go v8.0.0+incompatible
(The +metadata suffix is a standard part of semantic versioning,
and that suffix is ignored when comparing two versions for
precedence or equality. As part of canonicalizing versions
recorded in go.mod, the go command has always stripped all
such suffixes. It still strips nearly all: only +incompatible is
preserved now.)
In addition to recognizing the +incompatible, the code that
maps a commit hash to a version will use that form when
appropriate, so that
go get k8s.io/client-go@7d04d0
will choose k8s.io/client-go@v8.0.0+incompatible.
Also, the code that computes the list of available versions from
a given source code repository also maps old tags to +incompatible
versions, for any tagged commit in which a go.mod file does not exist.
Therefore
go list -m -versions k8s.io/client-go@latest
will show
k8s.io/client-go v1.4.0 v1.5.0 v1.5.1 v2.0.0-alpha.0+incompatible ... v8.0.0+incompatible
and similarly
go get k8s.io/client-go
will now choose v8.0.0+incompatible as the meaning of "latest tagged version".
The extraction of +incompatible versions from source code repos
depends on a codehost.Repo method ReadFileRevs, to do a bulk read
of multiple revisions of a file. That method is only implemented for git in this CL.
Future CLs will need to add support for that method to the other repository
implementations.
Documentation for this change is in CL 124515.
Fixes #26238.

This CL corresponds to CL 123361, the final manual CL in that repo,
making this the final manual sync.
All future commits will happen in this repo (the main Go repo),
and we'll update x/vgo automatically with a fixed patch+script.

This CL corresponds to golang.org/cl/118096 (7fbc8df48a7)
in the vgo repo.
It copies the bulk of the code from vgo back into the main repo,
but completely disabled - vgo.Init is a no-op and vgo.Enabled
returns false unconditionally.
The point of this CL is to make the two trees easier to diff and
to make future syncs smaller.
