The initial plan is integration into [glide](https://github.com/Masterminds/glide), but `vsolver` could be used by any tool interested in [fully solving](www.mancoosi.org/edos/manager/) [the package management problem](https://medium.com/@sdboyer/so-you-want-to-write-a-package-manager-4ae9c17d9527). + +**NOTE - `vsolver` is super-extra-much not functional yet :)** + +The current implementation is based heavily on the solver used in Dart's [pub](https://github.com/dart-lang/pub/tree/master/lib/src/solver) package management tool.

We love the idea of Go packages as standalone, self-describing code. Unfortunately, though, that idea goes off the rails as soon as versioning and cross-project/repository dependencies happen, because [universe alignment is hard](https://medium.com/@sdboyer/so-you-want-to-write-a-package-manager-4ae9c17d9527). + +Disliking solvers because *"It seems complicated, idiomatic Go things are simple!"* or *"(Tool X) uses a solver and I don't like it"* is just shooting the messenger.

For example, + + raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",} + vs := make([]*semver.Version, len(raw)) + for i, r := range raw { + v, err := semver.NewVersion(r) + if err != nil { + t.Errorf("Error parsing version: %s", err) + } + + vs[i] = v + } + + sort.Sort(semver.Collection(vs)) + +## Checking Version Constraints + +Checking a version against version constraints is one of the most featureful +parts of the package. + + c, err := semver.NewConstraint(">= 1.2.3") + if err != nil { + // Handle constraint not being parseable. + } + + v, _ := semver.NewVersion("1.3") + if err != nil { + // Handle version not being parseable. + } + // Check if the version meets the constraints. The a variable will be true. + a := c.Check(v) + +## Basic Comparisons + +There are two elements to the comparisons. First, a comparison string is a list +of comma separated and comparisons. These are then separated by || separated or +comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a +comparison that's greater than or equal to 1.2 and less than 3.0.0 or is +greater than or equal to 4.2.3. + +The basic comparisons are: + +* `=`: equal (aliased to no operator) +* `!=`: not equal +* `>`: greater than +* `<`: less than +* `>=`: greater than or equal to +* `<=`: less than or equal to + +## Hyphen Range Comparisons + +There are multiple methods to handle ranges and the first is hyphens ranges. +These look like: + +* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5` +* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5` + +## Wildcards In Comparisons + +The `x`, `X`, and `*` characters can be used as a wildcard character. This works +for all comparison operators. When used on the `=` operator it falls +back to the pack level comparison (see tilde below). For example, + +* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` +* `>= 1.2.x` is equivalent to `>= 1.2.0` +* `<= 2.x` is equivalent to `<= 3` +* `*` is equivalent to `>= 0.0.0` + +## Tilde Range Comparisons (Patch) + +The tilde (`~`) comparison operator is for patch level ranges when a minor +version is specified and major level changes when the minor number is missing. +For example, + +* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0` +* `~1` is equivalent to `>= 1, < 2` +* `~2.3` is equivalent to `>= 2.3, < 2.4` +* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` +* `~1.x` is equivalent to `>= 1, < 2` + +## Caret Range Comparisons (Major) + +The caret (`^`) comparison operator is for major level changes. This is useful +when comparisons of API versions as a major change is API breaking. For example, + +* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` +* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` +* `^2.3` is equivalent to `>= 2.3, < 3` +* `^2.x` is equivalent to `>= 2.0.0, < 3` + +# Validation + +In addition to testing a version against a constraint, a version can be validated +against a constraint. When validation fails a slice of errors containing why a +version didn't meet the constraint is returned. For example, + + c, err := semver.NewConstraint("<= 1.2.3, >= 1.4") + if err != nil { + // Handle constraint not being parseable. + } + + v, _ := semver.NewVersion("1.3") + if err != nil { + // Handle version not being parseable. + } + + // Validate a version against a constraint. + a, msgs := c.Validate(v) + // a is false + for _, m := range msgs { + fmt.Println(m) + + // Loops over the errors which would read + // "1.3 is greater than 1.2.3" + // "1.3 is less than 1.4" + } + +# Contribute + +If you find an issue or want to contribute please file an [issue](https://github.com/Masterminds/semver/issues) +or [create a pull request](https://github.com/Masterminds/semver/pulls). diff --git a/vendor/github.com/Masterminds/semver/appveyor.yml b/vendor/github.com/Masterminds/semver/appveyor.yml new file mode 100644 index 0000000000..cf7801b8a6 --- /dev/null +++ b/vendor/github.com/Masterminds/semver/appveyor.yml @@ -0,0 +1,22 @@ +version: build-{build}.{branch} + +clone_folder: C:\gopath\src\github.com\Masterminds\semver +shallow_clone: true + +environment: + GOPATH: C:\gopath + +platform: + - x64 + +install: + - go version + - go env + +build_script: + - go install -v ./... + +test_script: + - go test -v + +deploy: off diff --git a/vendor/github.com/Masterminds/semver/collection.go b/vendor/github.com/Masterminds/semver/collection.go new file mode 100644 index 0000000000..a78235895f --- /dev/null +++ b/vendor/github.com/Masterminds/semver/collection.go @@ -0,0 +1,24 @@ +package semver + +// Collection is a collection of Version instances and implements the sort +// interface.

ability to: + + * Parse semantic versions + * Sort semantic versions + * Check if a semantic version fits within a set of constraints + * Optionally work with a `v` prefix + +Parsing Semantic Versions + +To parse a semantic version use the `NewVersion` function. For example, + + v, err := semver.NewVersion("1.2.3-beta.1+build345") + +If there is an error the version wasn't parseable. The version object has methods +to get the parts of the version, compare it to other versions, convert the +version back into a string, and get the original string. For more details +please see the documentation at https://godoc.org/github.com/Masterminds/semver. + +Sorting Semantic Versions + +A set of versions can be sorted using the `sort` package from the standard library. +For example, + + raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",} + vs := make([]*semver.Version, len(raw)) + for i, r := range raw { + v, err := semver.NewVersion(r) + if err != nil { + t.Errorf("Error parsing version: %s", err) + } + + vs[i] = v + } + + sort.Sort(semver.Collection(vs)) + +Checking Version Constraints + +Checking a version against version constraints is one of the most featureful +parts of the package. + + c, err := semver.NewConstraint(">= 1.2.3") + if err != nil { + // Handle constraint not being parseable. + } + + v, _ := semver.NewVersion("1.3") + if err != nil { + // Handle version not being parseable. + } + // Check if the version meets the constraints. The a variable will be true. + a := c.Check(v) + +Basic Comparisons + +There are two elements to the comparisons. First, a comparison string is a list +of comma separated and comparisons. These are then separated by || separated or +comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a +comparison that's greater than or equal to 1.2 and less than 3.0.0 or is +greater than or equal to 4.2.3. + +The basic comparisons are: + + * `=`: equal (aliased to no operator) + * `!=`: not equal + * `>`: greater than + * `<`: less than + * `>=`: greater than or equal to + * `<=`: less than or equal to + +Hyphen Range Comparisons + +There are multiple methods to handle ranges and the first is hyphens ranges. +These look like: + + * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5` + * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5` + +Wildcards In Comparisons + +The `x`, `X`, and `*` characters can be used as a wildcard character. This works +for all comparison operators. When used on the `=` operator it falls +back to the pack level comparison (see tilde below). For example, + + * `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` + * `>= 1.2.x` is equivalent to `>= 1.2.0` + * `<= 2.x` is equivalent to `<= 3` + * `*` is equivalent to `>= 0.0.0` + +Tilde Range Comparisons (Patch) + +The tilde (`~`) comparison operator is for patch level ranges when a minor +version is specified and major level changes when the minor number is missing. +For example, + + * `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0` + * `~1` is equivalent to `>= 1, < 2` + * `~2.3` is equivalent to `>= 2.3, < 2.4` + * `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` + * `~1.x` is equivalent to `>= 1, < 2` + +Caret Range Comparisons (Major) + +The caret (`^`) comparison operator is for major level changes. This is useful +when comparisons of API versions as a major change is API breaking. For example, + + * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` + * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` + * `^2.3` is equivalent to `>= 2.3, < 3` + * `^2.x` is equivalent to `>= 2.0.0, < 3` +*/ +package semver diff --git a/vendor/github.com/Masterminds/semver/version.go b/vendor/github.com/Masterminds/semver/version.go new file mode 100644 index 0000000000..75dbbc097d --- /dev/null +++ b/vendor/github.com/Masterminds/semver/version.go @@ -0,0 +1,271 @@ +package semver + +import ( + "bytes" + "errors" + "fmt" + "regexp" + "strconv" + "strings" +) + +// The compiled version of the regex created at init() is cached here so it +// only needs to be created once. +var versionRegex *regexp.Regexp + +var ( + // ErrInvalidSemVer is returned a version is found to be invalid when + // being parsed. + ErrInvalidSemVer = errors.New("Invalid Semantic Version") +) + +// SemVerRegex id the regular expression used to parse a semantic version. +const SemVerRegex string = `v?([0-9]+)(\.[0-9]+)?(\.[0-9]+)?` + + `(-([0-9A-Za-z\-]+(\.[0-9A-Za-z\-]+)*))?` + + `(\+([0-9A-Za-z\-]+(\.[0-9A-Za-z\-]+)*))?` + +// Version represents a single semantic version. +type Version struct { + major, minor, patch int64 + pre string + metadata string + original string +} + +func init() { + versionRegex = regexp.MustCompile("^" + SemVerRegex + "$") +} + +// NewVersion parses a given version and returns an instance of Version or +// an error if unable to parse the version. +func NewVersion(v string) (*Version, error) { + m := versionRegex.FindStringSubmatch(v) + if m == nil { + return nil, ErrInvalidSemVer + } + + sv := &Version{ + metadata: m[8], + pre: m[5], + original: v, + } + + var temp int64 + temp, err := strconv.ParseInt(m[1], 10, 32) + if err != nil { + return nil, fmt.Errorf("Error parsing version segment: %s", err) + } + sv.major = temp + + if m[2] != "" { + temp, err = strconv.ParseInt(strings.TrimPrefix(m[2], "."), 10, 32) + if err != nil { + return nil, fmt.Errorf("Error parsing version segment: %s", err) + } + sv.minor = temp + } else { + sv.minor = 0 + } + + if m[3] != "" { + temp, err = strconv.ParseInt(strings.TrimPrefix(m[3], "."), 10, 32) + if err != nil { + return nil, fmt.Errorf("Error parsing version segment: %s", err) + } + sv.patch = temp + } else { + sv.patch = 0 + } + + return sv, nil +} + +// String converts a Version object to a string. +// Note, if the original version contained a leading v this version will not. +// See the Original() method to retrieve the original value.

The version object has methods -to get the parts of the version, compare it to other versions, convert the -version back into a string, and get the original string.

The a variable will be true. - a := c.Check(v) - -## Basic Comparisons - -There are two elements to the comparisons. First, a comparison string is a list -of comma separated and comparisons. These are then separated by || separated or -comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a -comparison that's greater than or equal to 1.2 and less than 3.0.0 or is -greater than or equal to 4.2.3. - -The basic comparisons are: - -* `=`: equal (aliased to no operator) -* `!=`: not equal -* `>`: greater than -* `<`: less than -* `>=`: greater than or equal to -* `<=`: less than or equal to - -## Hyphen Range Comparisons - -There are multiple methods to handle ranges and the first is hyphens ranges. -These look like: - -* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5` -* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5` - -## Wildcards In Comparisons - -The `x`, `X`, and `*` characters can be used as a wildcard character. This works -for all comparison operators. When used on the `=` operator it falls -back to the pack level comparison (see tilde below). For example, - -* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` -* `>= 1.2.x` is equivalent to `>= 1.2.0` -* `<= 2.x` is equivalent to `<= 3` -* `*` is equivalent to `>= 0.0.0` - -## Tilde Range Comparisons (Patch) - -The tilde (`~`) comparison operator is for patch level ranges when a minor -version is specified and major level changes when the minor number is missing. -For example, - -* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0` -* `~1` is equivalent to `>= 1, < 2` -* `~2.3` is equivalent to `>= 2.3, < 2.4` -* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` -* `~1.x` is equivalent to `>= 1, < 2` - -## Caret Range Comparisons (Major) - -The caret (`^`) comparison operator is for major level changes. This is useful -when comparisons of API versions as a major change is API breaking. For example, - -* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` -* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` -* `^2.3` is equivalent to `>= 2.3, < 3` -* `^2.x` is equivalent to `>= 2.0.0, < 3` - -# Validation - -In addition to testing a version against a constraint, a version can be validated -against a constraint.

-Specifically it provides the ability to: - - * Parse semantic versions - * Sort semantic versions - * Check if a semantic version fits within a set of constraints - * Optionally work with a `v` prefix - -Parsing Semantic Versions - -To parse a semantic version use the `NewVersion` function. For example, - - v, err := semver.NewVersion("1.2.3-beta.1+build345") - -If there is an error the version wasn't parseable. The version object has methods -to get the parts of the version, compare it to other versions, convert the -version back into a string, and get the original string. For more details -please see the documentation at https://godoc.org/github.com/Masterminds/semver. - -Sorting Semantic Versions - -A set of versions can be sorted using the `sort` package from the standard library. -For example, - - raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",} - vs := make([]*semver.Version, len(raw)) - for i, r := range raw { - v, err := semver.NewVersion(r) - if err != nil { - t.Errorf("Error parsing version: %s", err) - } - - vs[i] = v - } - - sort.Sort(semver.Collection(vs)) - -Checking Version Constraints - -Checking a version against version constraints is one of the most featureful -parts of the package. - - c, err := semver.NewConstraint(">= 1.2.3") - if err != nil { - // Handle constraint not being parseable. - } - - v, _ := semver.NewVersion("1.3") - if err != nil { - // Handle version not being parseable. - } - // Check if the version meets the constraints. The a variable will be true. - a := c.Check(v) - -Basic Comparisons - -There are two elements to the comparisons. First, a comparison string is a list -of comma separated and comparisons. These are then separated by || separated or -comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a -comparison that's greater than or equal to 1.2 and less than 3.0.0 or is -greater than or equal to 4.2.3. - -The basic comparisons are: - - * `=`: equal (aliased to no operator) - * `!=`: not equal - * `>`: greater than - * `<`: less than - * `>=`: greater than or equal to - * `<=`: less than or equal to - -Hyphen Range Comparisons - -There are multiple methods to handle ranges and the first is hyphens ranges. -These look like: - - * `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5` - * `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5` - -Wildcards In Comparisons - -The `x`, `X`, and `*` characters can be used as a wildcard character. This works -for all comparison operators. When used on the `=` operator it falls -back to the pack level comparison (see tilde below). For example, - - * `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` - * `>= 1.2.x` is equivalent to `>= 1.2.0` - * `<= 2.x` is equivalent to `<= 3` - * `*` is equivalent to `>= 0.0.0` - -Tilde Range Comparisons (Patch) - -The tilde (`~`) comparison operator is for patch level ranges when a minor -version is specified and major level changes when the minor number is missing. -For example, - - * `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0` - * `~1` is equivalent to `>= 1, < 2` - * `~2.3` is equivalent to `>= 2.3, < 2.4` - * `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0` - * `~1.x` is equivalent to `>= 1, < 2` - -Caret Range Comparisons (Major) - -The caret (`^`) comparison operator is for major level changes. This is useful -when comparisons of API versions as a major change is API breaking. For example, - - * `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0` - * `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0` - * `^2.3` is equivalent to `>= 2.3, < 3` - * `^2.x` is equivalent to `>= 2.0.0, < 3` -*/ -package semver diff --git a/vendor/github.com/Masterminds/semver/version.go b/vendor/github.com/Masterminds/semver/version.go deleted file mode 100644 index d6b6773a68..0000000000 --- a/vendor/github.com/Masterminds/semver/version.go +++ /dev/null @@ -1,347 +0,0 @@ -package semver - -import ( - "bytes" - "errors" - "fmt" - "regexp" - "strconv" - "strings" -) - -// The compiled version of the regex created at init() is cached here so it -// only needs to be created once. -var versionRegex *regexp.Regexp - -var ( - // ErrInvalidSemVer is returned a version is found to be invalid when - // being parsed. - ErrInvalidSemVer = errors.New("Invalid Semantic Version") -) - -// Controls whether or not parsed constraints are cached -var cacheVersions = true -var versionCache = make(map[string]*Version) - -// SemVerRegex id the regular expression used to parse a semantic version. -const SemVerRegex string = `v?([0-9]+)(\.[0-9]+)?(\.[0-9]+)?` + - `(-([0-9A-Za-z\-]+(\.[0-9A-Za-z\-]+)*))?` + - `(\+([0-9A-Za-z\-]+(\.[0-9A-Za-z\-]+)*))?` - -// Version represents a single semantic version. -type Version struct { - major, minor, patch int64 - pre string - metadata string - original string -} - -func init() { - versionRegex = regexp.MustCompile("^" + SemVerRegex + "$") -} - -// NewVersion parses a given version and returns an instance of Version or -// an error if unable to parse the version. -func NewVersion(v string) (*Version, error) { - if cacheVersions { - if sv, exists := versionCache[v]; exists { - return sv, nil - } - } - - m := versionRegex.FindStringSubmatch(v) - if m == nil { - return nil, ErrInvalidSemVer - } - - sv := &Version{ - metadata: m[8], - pre: m[5], - original: v, - } - - var temp int64 - temp, err := strconv.ParseInt(m[1], 10, 32) - if err != nil { - return nil, fmt.Errorf("Error parsing version segment: %s", err) - } - sv.major = temp - - if m[2] != "" { - temp, err = strconv.ParseInt(strings.TrimPrefix(m[2], "."), 10, 32) - if err != nil { - return nil, fmt.Errorf("Error parsing version segment: %s", err) - } - sv.minor = temp - } else { - sv.minor = 0 - } - - if m[3] != "" { - temp, err = strconv.ParseInt(strings.TrimPrefix(m[3], "."), 10, 32) - if err != nil { - return nil, fmt.Errorf("Error parsing version segment: %s", err) - } - sv.patch = temp - } else { - sv.patch = 0 - } - - if cacheVersions { - versionCache[v] = sv - } - - return sv, nil -} - -// String converts a Version object to a string. -// Note, if the original version contained a leading v this version will not. -// See the Original() method to retrieve the original value.

450/916] Don't return futures from pathDeducers This is good architecture in general - the pathDeducers don't need to return futures themselves, as long as they return futurizable results - but it's particularly important for testing, as there are no facilities by which we can inspect and validate the results of pathDeducers' work when that state is held in future closures. --- remote.go | 200

If we're likely to need it, though, then to avoid complexity growth owing to doing a ton of background work (which entails synchronization), we do async prefetching only if we have a strong reason to believe it will result in parallelism. --- bridge.go | 9 ++++++++- solver.go | 37 +++++++++++++++++++++++++++++++++++-- 2 files changed, 43 insertions(+), 3 deletions(-) diff --git a/bridge.go b/bridge.go index 00fc30a083..298b0232f6 100644 --- a/bridge.go +++ b/bridge.go @@ -439,7 +439,14 @@ func (b *bridge) breakLock() { // // TODO(sdboyer) use this as an opportunity to detect // inconsistencies between upstream and the lock (e.g., moved tags)? - go b.sm.ListPackages(lp.pi, lp.Version()) + pi, v := lp.pi, lp.Version() + go func() { + // Sync first + b.sm.SyncSourceFor(pi) + // Preload the package info for the locked version, too, as + // we're more likely to need that + b.sm.ListPackages(pi, v) + }() } } } diff --git a/solver.go b/solver.go index d82a40c07c..34a8c3c923 100644 --- a/solver.go +++ b/solver.go @@ -474,6 +474,13 @@ func (s *solver) selectRoot() error { } for _, dep := range deps { + // If we have no lock, or if this dep isn't in the lock, then prefetch + // it.

The first is when populating the atomWithPackages representing the root package. PackageTree.Packages was ranged over and the keys used to construct a []string, which was then saved as package list on the awp. This probably wasn't causing non-determinism, but it was an easy fix, and a one-time (root-only) sort, so no reason not to fix it. The other case was walking a map of needed external packages in getImportsAndConstraintsOf(), which ultimately determined the order in which an atom's dependencies were checked against the satisfiability conditions.

Those packages that are only imported by other internal packages are missed. --- analysis.go | 139 +++++++++++++++++++++++++++++------------- analysis_test.go | 34 ++++++----- solve_bimodal_test.go | 2 +- 3 files changed, 115 insertions(+), 60 deletions(-) diff --git a/analysis.go b/analysis.go index bbae13d955..b3581b2c23 100644 --- a/analysis.go +++ b/analysis.go @@ -48,9 +48,6 @@ func doIsStdLib(path string) bool { // ListPackages reports Go package information about all directories in the tree // at or below the provided fileRoot. // -// Directories without any valid Go files are excluded.

It was trying to do a "bit" of the search work before the real algorithm; however, the final else statement was causing some internal imports to be dropped if the referent had already been visited. The bug was intermittent, as it depended on map iteration order. This also solves the secondary problem of inaccurate backpropagation/poisoning in wmToReach itself, as the internal linkage data it's operating on is now reliable. --- analysis.go | 19 +++------ analysis_test.go | 103 +++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 109 insertions(+), 13 deletions(-) diff --git a/analysis.go b/analysis.go index 0afe95fdc1..f81d8f349f 100644 --- a/analysis.go +++ b/analysis.go @@ -462,9 +462,10 @@ func (t PackageTree) ToReachMaps(main, tests bool, ignore map[string]bool) (ex R } imps = imps[:0] - imps = p.Imports if tests { - imps = dedupeStrings(imps, p.TestImports) + imps = dedupeStrings(p.Imports, p.TestImports) + } else { + imps = p.Imports } w := wm{ @@ -472,8 +473,9 @@ func (t PackageTree) ToReachMaps(main, tests bool, ignore map[string]bool) (ex R in: make(map[string]bool), } + // For each import, decide whether it should be ignored, or if it + // belongs in the external or internal imports list. for _, imp := range imps { - // Skip ignored imports if ignore[imp] { continue } @@ -481,16 +483,7 @@ func (t PackageTree) ToReachMaps(main, tests bool, ignore map[string]bool) (ex R if !eqOrSlashedPrefix(imp, t.ImportRoot) { w.ex[imp] = true } else { - if w2, seen := workmap[imp];

Using the Google BigQuery public github dataset, I've checked the usernames of all public commits against the currently defined regex in deduce.go. From these results I've concluded that usernames with multiple consecutive hyphens and usernames that end with a hyphen were allowed in the past and do exist. Fortunately these are the only exceptions I've found, there were no usernames that started with a hyphen or contained any other special characters.

Simply asking clarifying questions on these issues is helpful! -* **Identifying missed use cases:** the loose `gps` rule of thumb is, "if you can do - it in Go, we support it in `gps`." Posting issues about cases we've missed - helps us reach that goal. -* **Writing tests:** in the same vein, `gps` has a [large suite](https://github.com/golang/dep/gps/blob/master/CODE_OF_CONDUCT.md) of solving tests, but - they still only scratch the surface. Writing tests is not only helpful, but is - also a great way to get a feel for how `gps` works. -* **Suggesting enhancements:** `gps` has plenty of missing chunks. Help fill them in! -* **Reporting bugs**: `gps` being a library means this isn't always the easiest. - However, you could always compile the [example](https://github.com/golang/dep/gps/blob/master/example.go), run that against some of - your projects, and report problems you encounter. -* **Building experimental tools with `gps`:** probably the best and fastest ways to - kick the tires! - -`gps` is still beta-ish software. There are plenty of bugs to squash! APIs are -stabilizing, but are still subject to change. - -## Issues and Pull Requests - -Pull requests are the preferred way to submit changes to 'gps'.

- ---- - -`gps` is the Go Packaging Solver. It is an engine for tackling dependency -management problems in Go. It is trivial - [about 35 lines of -code](https://github.com/golang/dep/gps/blob/master/example.go) - to replicate the -fetching bits of `go get` using `gps`. - -`gps` is _not_ Yet Another Go Package Management Tool. Rather, it's a library -that package management (and adjacent) tools can use to solve the -[hard](https://en.wikipedia.org/wiki/Boolean_satisfiability_problem) parts of -the problem in a consistent, -[holistic](https://medium.com/@sdboyer/so-you-want-to-write-a-package-manager-4ae9c17d9527) -way. It is a distillation of the ideas behind language package managers like -[bundler](http://bundler.io), [npm](https://www.npmjs.com/), -[elm-package](https://github.com/elm-lang/elm-package), -[cargo](https://crates.io/) (and others) into a library, artisanally -handcrafted with ❤️ for Go's specific requirements. - -`gps` was [on track](https://github.com/Masterminds/glide/issues/565) to become -the engine behind [glide](https://glide.sh); however, those efforts have been -discontinued in favor of gps powering the [experimental, eventually-official -Go tooling](https://github.com/golang/dep). - -The wiki has a [general introduction to the `gps` -approach](https://github.com/golang/dep/gps/wiki/Introduction-to-gps), as well -as guides for folks [implementing -tools](https://github.com/golang/dep/gps/wiki/gps-for-Implementors) or [looking -to contribute](https://github.com/golang/dep/gps/wiki/gps-for-Contributors). - -## Wait...a package management _library_?! - -Yup. See [the rationale](https://github.com/golang/dep/gps/wiki/Rationale). - -## Features - -A feature list for a package management library is a bit different than one for -a package management tool. Instead of listing the things an end-user can do, -we list the choices a tool *can* make and offer, in some form, to its users, as -well as the non-choices/assumptions/constraints that `gps` imposes on a tool. - -### Non-Choices - -We'd love for `gps`'s non-choices to be noncontroversial. But that's not always -the case. - -Nevertheless, these non-choices remain because, taken as a whole, they make -experiments and discussion around Go package management coherent and -productive. - -* Go >=1.6, or 1.5 with `GO15VENDOREXPERIMENT = 1` set -* Everything under `vendor/` is volatile and controlled solely by the tool -* A central cache of repositories is used (cannot be `GOPATH`) -* A [**project**](https://godoc.org/github.com/golang/dep/gps#ProjectRoot) concept: - a tree of packages, all covered by one `vendor` directory -* A [**manifest** and - **lock**](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#manifests-and-locks) - approach to tracking version and constraint information -* Upstream sources are one of `git`, `bzr`, `hg` or `svn` repositories -* What the available versions are for a given project/repository (all branches, tags, or revs are eligible) - * In general, semver tags are preferred to branches, are preferred to plain tags -* The actual packages that must be present (determined through import graph static analysis) - * How the import graph is statically analyzed - similar to `go/build`, but with a combinatorial view of build tags ([not yet implemented](https://github.com/golang/dep/gps/issues/99)) -* All packages from the same source (repository) must be the same version -* Package import cycles are not allowed ([not yet implemented](https://github.com/golang/dep/gps/issues/66)) - -There are also some current non-choices that we would like to push into the realm of choice: - -* Importable projects that are not bound to the repository root -* Source inference around different import path patterns (e.g., how `github.com/*` or `my_company/*` are handled) - -### Choices - -These choices represent many of the ways that `gps`-based tools could -substantively differ from each other. - -Some of these are choices designed to encompass all options for topics on which -reasonable people have disagreed. Others are simply important controls that no -general library could know _a priori_. - -* How to store manifest and lock information (file(s)? a db?) -* Which of the other package managers to interoperate with -* Which types of version constraints to allow the user to specify (e.g., allowing [semver ranges](https://docs.npmjs.com/misc/semver) or not) -* Whether or not to strip nested `vendor` directories -* Which packages in the import graph to [ignore](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#ignoring-packages) (if any) -* What constraint [overrides](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#overrides) to apply (if any) -* What [informational output](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#trace-and-tracelogger) to show the end user -* What dependency version constraints are declared by the [root project](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#manifest-data) -* What dependency version constraints are declared by [all dependencies](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#the-projectanalyzer) -* Given a [previous solution](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#lock-data), [which versions to let change, and how](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#tochange-changeall-and-downgrade) - * In the absence of a previous solution, whether or not to use [preferred versions](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#preferred-versions) -* Allowing, or not, the user to [swap in different source locations](https://github.com/golang/dep/gps/wiki/gps-for-Implementors#projectidentifier) for import paths (e.g. forks) -* Specifying additional input/source packages not reachable from the root import graph - -This list may not be exhaustive - see the -[implementor's guide](https://github.com/golang/dep/gps/wiki/gps-for-Implementors) -for a proper treatment. - -## Contributing - -Yay, contributing!

It is a distillation of the ideas behind language package managers like -[bundler](http://bundler.io), [npm](https://www.npmjs.com/), -[elm-package](https://github.com/elm-lang/elm-package), -[cargo](https://crates.io/) (and others) into a library, artisanally -handcrafted with ❤️ for Go's specific requirements. - -`gps` was [on track](https://github.com/Masterminds/glide/issues/565) to become -the engine behind [glide](https://glide.sh); however, those efforts have been -discontinued in favor of gps powering the [experimental, eventually-official -Go tooling](https://github.com/golang/dep). - -The wiki has a [general introduction to the `gps` -approach](https://github.com/golang/dep/gps/wiki/Introduction-to-gps), as well -as guides for folks [implementing -tools](https://github.com/golang/dep/gps/wiki/gps-for-Implementors) or [looking -to contribute](https://github.com/golang/dep/gps/wiki/gps-for-Contributors). - -## Wait...a package management _library_?! - -Yup.
