## Contribution guidelines.
So you wish to contribute to this project? Fantastic!
Here are a few guidelines to help you do this in a
streamlined fashion.
## Bug reports
When supplying a bug report, please consider the following guidelines.
These serve to make it easier for us to address the issue and find a solution.
Most of these are pretty self-evident, but sometimes it is still necessary
to reiterate them.
* Be clear in the way you express the problem. Use simple language and
just enough of it to clearly define the issue. Not everyone is a native
English speaker. And while most can handle themselves pretty well,
it helps to stay away from more esoteric vocabulary.
Be patient with non-native English speakers. If their bug reports
or comments are hard to understand, just ask for clarification.
Do not start guessing at their meaning, as this may just lead to
more confusion and misunderstandings.
* Clearly define any information which is relevant to the problem.
This includes library versions, operating system and any other
external dependencies which may be needed.
* Where applicable, provide a step-by-step listing of the way to
reproduce the problem. Make sure this is the simplest possible
way to do so. Omit any and all unneccesary steps, because they may
just complicate our understanding of the real problem.
If need be, create a whole new code project on your local machine,
which specifically tries to create the problem you are running into;
nothing more, nothing less.
Include this program in the bug report. It often suffices to paste
the code in a [Gist](https://gist.github.com) or on the
[Go playground](http://play.golang.org).
* If possible, provide us with a listing of the steps you have already
undertaken to solve the problem. This can save us a great deal of
wasted time, trying out solutions you have already covered.
## Pull requests
Bug reports are great. Supplying fixes to bugs is even better.
When submitting a pull request, the following guidelines are
good to keep in mind:
* `go fmt`: **Always** run your code through `go fmt`, before
committing it. Code has to be readable by many different
people. And the only way this will be as painless as possible,
is if we all stick to the same code style.
Some of our projects may have automated build-servers hooked up
to commit hooks. These will vet any submitted code and determine
if it meets a set of properties. One of which is code formatting.
These servers will outright deny a submission which has not been
run through `go fmt`, even if the code itself is correct.
We try to maintain a zero-tolerance policy on this matter,
because consistently formatted code makes life a great deal
easier for everyone involved.
* Commit log messages: When committing changes, do so often and
clearly -- Even if you have changed only 1 character in a code
comment. This means that commit log messages should clearly state
exactly what the change does and why. If it fixes a known issue,
then mention the issue number in the commit log. E.g.:
> Fixes return value for `foo/boo.Baz()` to be consistent with
> the rest of the API. This addresses issue #32
Do not pile a lot of unrelated changes into a single commit.
Pick and choose only those changes for a single commit, which are
directly related. We would much rather see a hundred commits
saying nothing but `"Runs go fmt"` in between any real fixes
than have these style changes embedded in those real fixes.
It creates a lot of noise when trying to review code.

## bindata
[![Build Status](https://cloud.drone.io/api/badges/go-bindata/go-bindata/status.svg)](https://cloud.drone.io/go-bindata/go-bindata)
[![Go Report Card](https://goreportcard.com/badge/github.com/go-bindata/bindata)](https://goreportcard.com/report/github.com/go-bindata/bindata)
This package converts any file into managable Go source code. Useful for
embedding binary data into a go program. The file data is optionally gzip
compressed before being converted to a raw byte slice.
It comes with a command line tool in the `go-bindata` sub directory.
This tool offers a set of command line options, used to customize the
output being generated.
### Installation
To install the library and command line program, use the following:
go get -u github.com/go-bindata/go-bindata/...
### Usage
Conversion is done on one or more sets of files. They are all embedded in a new
Go source file, along with a table of contents and an `Asset` function,
which allows quick access to the asset, based on its name.
The simplest invocation generates a `bindata.go` file in the current
working directory. It includes all assets from the `data` directory.
$ go-bindata data/
To include all input sub-directories recursively, use the elipsis postfix
as defined for Go import paths. Otherwise it will only consider assets in the
input directory itself.
$ go-bindata data/...
To specify the name of the output file being generated, we use the following:
$ go-bindata -o myfile.go data/
Multiple input directories can be specified if necessary.
$ go-bindata dir1/... /path/to/dir2/... dir3
The following paragraphs detail some of the command line options which can be
supplied to `go-bindata`. Refer to the `testdata/out` directory for various
output examples from the assets in `testdata/in`. Each example uses different
command line options.
To ignore files, pass in regexes using -ignore, for example:
$ go-bindata -ignore=\\.gitignore data/...
### Accessing an asset
To access asset data, we use the `Asset(string) ([]byte, error)` function which
is included in the generated output.
```go
data, err := Asset("pub/style/foo.css")
if err != nil {
// Asset was not found.
}
// use asset data
```
### Debug vs Release builds
When invoking the program with the `-debug` flag, the generated code does
not actually include the asset data. Instead, it generates function stubs
which load the data from the original file on disk. The asset API remains
identical between debug and release builds, so your code will not have to
change.
This is useful during development when you expect the assets to change often.
The host application using these assets uses the same API in both cases and
will not have to care where the actual data comes from.
An example is a Go webserver with some embedded, static web content like
HTML, JS and CSS files. While developing it, you do not want to rebuild the
whole server and restart it every time you make a change to a bit of
javascript. You just want to build and launch the server once. Then just press
refresh in the browser to see those changes. Embedding the assets with the
`debug` flag allows you to do just that. When you are finished developing and
ready for deployment, just re-invoke `go-bindata` without the `-debug` flag.
It will now embed the latest version of the assets.
### Lower memory footprint
Using the `-nomemcopy` flag, will alter the way the output file is generated.
It will employ a hack that allows us to read the file data directly from
the compiled program's `.rodata` section. This ensures that when we
call our generated function, we omit unnecessary memcopies.
The downside of this, is that it requires dependencies on the `reflect` and
`unsafe` packages. These may be restricted on platforms like AppEngine and
thus prevent you from using this mode.
Another disadvantage is that the byte slice we create, is strictly read-only.
For most use-cases this is not a problem, but if you ever try to alter the
returned byte slice, a runtime panic is thrown. Use this mode only on target
platforms where memory constraints are an issue.
The default behaviour is to use the old code generation method. This
prevents the two previously mentioned issues, but will employ at least one
extra memcopy and thus increase memory requirements.
For instance, consider the following two examples:
This would be the default mode, using an extra memcopy but gives a safe
implementation without dependencies on `reflect` and `unsafe`:
```go
func myfile() []byte {
return []byte{0x89, 0x50, 0x4e, 0x47, 0x0d, 0x0a, 0x1a}
}
```
Here is the same functionality, but uses the `.rodata` hack.
The byte slice returned from this example can not be written to without
generating a runtime error.
```go
var _myfile = "\x89\x50\x4e\x47\x0d\x0a\x1a"
func myfile() []byte {
var empty [0]byte
sx := (*reflect.StringHeader)(unsafe.Pointer(&_myfile))
b := empty[:]
bx := (*reflect.SliceHeader)(unsafe.Pointer(&b))
bx.Data = sx.Data
bx.Len = len(_myfile)
bx.Cap = bx.Len
return b
}
```
### Optional compression
When the `-nocompress` flag is given, the supplied resource is *not* GZIP
compressed before being turned into Go code. The data should still be accessed
through a function call, so nothing changes in the usage of the generated file.
This feature is useful if you do not care for compression, or the supplied
resource is already compressed. Doing it again would not add any value and may
even increase the size of the data.
The default behaviour of the program is to use compression.
### Path prefix stripping
The keys used in the `_bindata` map, are the same as the input file name
passed to `go-bindata`. This includes the path. In most cases, this is not
desireable, as it puts potentially sensitive information in your code base.
For this purpose, the tool supplies another command line flag `-prefix`.
This accepts a portion of a path name, which should be stripped off from
the map keys and function names.
For example, running without the `-prefix` flag, we get:
$ go-bindata /path/to/templates/
_bindata["/path/to/templates/foo.html"] = path_to_templates_foo_html
Running with the `-prefix` flag, we get:
$ go-bindata -prefix "/path/to/" /path/to/templates/
_bindata["templates/foo.html"] = templates_foo_html
### Build tags
With the optional `-tags` flag, you can specify any go build tags that
must be fulfilled for the output file to be included in a build. This
is useful when including binary data in multiple formats, where the desired
format is specified at build time with the appropriate tags.
The tags are appended to a `// +build` line in the beginning of the output file
and must follow the build tags syntax specified by the go tool.
### Serve assets with `net/http`
With the `-fs` flag, `go-bindata` will add an `AssetFile()` method returning an `http.FileSystem` interface:
$ go-bindata -fs -prefix "static/" static/
Use `-prefix` flag to strip first level dir, then in your `net/http` router, you can use `AssetFile()` with `http.FileServer()` like:
```go
mux := http.NewServeMux()
mux.Handle("/static", http.FileServer(AssetFile()))
http.ListenAndServe(":8080", mux)
```

/*
bindata converts any file into manageable Go source code. Useful for
embedding binary data into a go program. The file data is optionally gzip
compressed before being converted to a raw byte slice.
The following paragraphs cover some of the customization options
which can be specified in the Config struct, which must be passed into
the Translate() call.
Debug vs Release builds
When used with the `Debug` option, the generated code does not actually include
the asset data. Instead, it generates function stubs which load the data from
the original file on disk. The asset API remains identical between debug and
release builds, so your code will not have to change.
This is useful during development when you expect the assets to change often.
The host application using these assets uses the same API in both cases and
will not have to care where the actual data comes from.
An example is a Go webserver with some embedded, static web content like
HTML, JS and CSS files. While developing it, you do not want to rebuild the
whole server and restart it every time you make a change to a bit of
javascript. You just want to build and launch the server once. Then just press
refresh in the browser to see those changes. Embedding the assets with the
`debug` flag allows you to do just that. When you are finished developing and
ready for deployment, just re-invoke `go-bindata` without the `-debug` flag.
It will now embed the latest version of the assets.
Lower memory footprint
The `NoMemCopy` option will alter the way the output file is generated.
It will employ a hack that allows us to read the file data directly from
the compiled program's `.rodata` section. This ensures that when we call
call our generated function, we omit unnecessary memcopies.
The downside of this, is that it requires dependencies on the `reflect` and
`unsafe` packages. These may be restricted on platforms like AppEngine and
thus prevent you from using this mode.
Another disadvantage is that the byte slice we create, is strictly read-only.
For most use-cases this is not a problem, but if you ever try to alter the
returned byte slice, a runtime panic is thrown. Use this mode only on target
platforms where memory constraints are an issue.
The default behaviour is to use the old code generation method. This
prevents the two previously mentioned issues, but will employ at least one
extra memcopy and thus increase memory requirements.
For instance, consider the following two examples:
This would be the default mode, using an extra memcopy but gives a safe
implementation without dependencies on `reflect` and `unsafe`:
func myfile() []byte {
return []byte{0x89, 0x50, 0x4e, 0x47, 0x0d, 0x0a, 0x1a}
}
Here is the same functionality, but uses the `.rodata` hack.
The byte slice returned from this example can not be written to without
generating a runtime error.
var _myfile = "\x89\x50\x4e\x47\x0d\x0a\x1a"
func myfile() []byte {
var empty [0]byte
sx := (*reflect.StringHeader)(unsafe.Pointer(&_myfile))
b := empty[:]
bx := (*reflect.SliceHeader)(unsafe.Pointer(&b))
bx.Data = sx.Data
bx.Len = len(_myfile)
bx.Cap = bx.Len
return b
}
Optional compression
The NoCompress option indicates that the supplied assets are *not* GZIP
compressed before being turned into Go code. The data should still be accessed
through a function call, so nothing changes in the API.
This feature is useful if you do not care for compression, or the supplied
resource is already compressed. Doing it again would not add any value and may
even increase the size of the data.
The default behaviour of the program is to use compression.
Path prefix stripping
The keys used in the `_bindata` map are the same as the input file name
passed to `go-bindata`. This includes the path. In most cases, this is not
desirable, as it puts potentially sensitive information in your code base.
For this purpose, the tool supplies another command line flag `-prefix`.
This accepts a portion of a path name, which should be stripped off from
the map keys and function names.
For example, running without the `-prefix` flag, we get:
$ go-bindata /path/to/templates/
_bindata["/path/to/templates/foo.html"] = path_to_templates_foo_html
Running with the `-prefix` flag, we get:
$ go-bindata -prefix "/path/to/" /path/to/templates/
_bindata["templates/foo.html"] = templates_foo_html
Build tags
With the optional Tags field, you can specify any go build tags that
must be fulfilled for the output file to be included in a build. This
is useful when including binary data in multiple formats, where the desired
format is specified at build time with the appropriate tags.
The tags are appended to a `// +build` line in the beginning of the output file
and must follow the build tags syntax specified by the go tool.

# errcheck
errcheck is a program for checking for unchecked errors in go programs.
![errcheck](https://github.com/kisielk/errcheck/workflows/errcheck/badge.svg)
## Install
go get -u github.com/kisielk/errcheck
errcheck requires Go 1.12 or newer, and depends on the package go/packages from the golang.org/x/tools repository.
## Use
For basic usage, just give the package path of interest as the first argument:
errcheck github.com/kisielk/errcheck/testdata
To check all packages beneath the current directory:
errcheck ./...
Or check all packages in your $GOPATH and $GOROOT:
errcheck all
errcheck also recognizes the following command-line options:
The `-tags` flag takes a space-separated list of build tags, just like `go
build`. If you are using any custom build tags in your code base, you may need
to specify the relevant tags here.
The `-asserts` flag enables checking for ignored type assertion results. It
takes no arguments.
The `-blank` flag enables checking for assignments of errors to the
blank identifier. It takes no arguments.
## Excluding functions
Use the `-exclude` flag to specify a path to a file containing a list of functions to
be excluded.
errcheck -exclude errcheck_excludes.txt path/to/package
The file should contain one function signature per line. The format for function signatures is
`package.FunctionName` while for methods it's `(package.Receiver).MethodName` for value receivers
and `(*package.Receiver).MethodName` for pointer receivers. If the function name is followed by string of form `(TYPE)`, then
the the function call is excluded only if the type of the first argument is `TYPE`. It also accepts a special suffix
`(os.Stdout)` and `(os.Stderr)`, which excludes the function only when the first argument is a literal `os.Stdout` or `os.Stderr`.
An example of an exclude file is:
io/ioutil.ReadFile
io.Copy(*bytes.Buffer)
io.Copy(os.Stdout)
// Sometimes we don't care if a HTTP request fails.
(*net/http.Client).Do
By default, the exclude list is combined with an internal list for functions in
the Go standard library that have an error return type but are documented to never
return an error. To disable the built-in exclude list, pass the `-excludeonly` flag.
Run errcheck in `-verbose` mode to see the resulting list of added excludes.
When using vendored dependencies, specify the full import path. For example:
* Your project's import path is `example.com/yourpkg`
* You've vendored `example.net/fmt2` as `vendor/example.net/fmt2`
* You want to exclude `fmt2.Println` from error checking
In this case, add this line to your exclude file:
```
example.com/yourpkg/vendor/example.net/fmt2.Println
```
Empty lines and lines starting with `//` are ignored.
### The deprecated method
The `-ignore` flag takes a comma-separated list of pairs of the form package:regex.
For each package, the regex describes which functions to ignore within that package.
The package may be omitted to have the regex apply to all packages.
For example, you may wish to ignore common operations like Read and Write:
errcheck -ignore '[rR]ead|[wW]rite' path/to/package
or you may wish to ignore common functions like the `print` variants in `fmt`:
errcheck -ignore 'fmt:[FS]?[Pp]rint*' path/to/package
The `-ignorepkg` flag takes a comma-separated list of package import paths
to ignore:
errcheck -ignorepkg 'fmt,encoding/binary' path/to/package
Note that this is equivalent to:
errcheck -ignore 'fmt:.*,encoding/binary:.*' path/to/package
If a regex is provided for a package `pkg` via `-ignore`, and `pkg` also appears
in the list of packages passed to `-ignorepkg`, the latter takes precedence;
that is, all functions within `pkg` will be ignored.
Note that by default the `fmt` package is ignored entirely, unless a regex is
specified for it. To disable this, specify a regex that matches nothing:
errcheck -ignore 'fmt:a^' path/to/package
The `-ignoretests` flag disables checking of `_test.go` files. It takes
no arguments.
## Exit Codes
errcheck returns 1 if any problems were found in the checked files.
It returns 2 if there were any other failures.
# Editor Integration
## Emacs
[go-errcheck.el](https://github.com/dominikh/go-errcheck.el)
integrates errcheck with Emacs by providing a `go-errcheck` command
and customizable variables to automatically pass flags to errcheck.
## Vim
[vim-go](https://github.com/fatih/vim-go) can run errcheck via both its `:GoErrCheck`
and `:GoMetaLinter` commands.

Golint is a linter for Go source code.
[![Go Reference](https://pkg.go.dev/badge/golang.org/x/lint.svg)](https://pkg.go.dev/golang.org/x/lint)
[![Build Status](https://travis-ci.org/golang/lint.svg?branch=master)](https://travis-ci.org/golang/lint)
## Installation
Golint requires a
[supported release of Go](https://golang.org/doc/devel/release.html#policy).
go get -u golang.org/x/lint/golint
To find out where `golint` was installed you can run `go list -f {{.Target}} golang.org/x/lint/golint`. For `golint` to be used globally add that directory to the `$PATH` environment setting.
## Usage
Invoke `golint` with one or more filenames, directories, or packages named
by its import path. Golint uses the same
[import path syntax](https://golang.org/cmd/go/#hdr-Import_path_syntax) as
the `go` command and therefore
also supports relative import paths like `./...`. Additionally the `...`
wildcard can be used as suffix on relative and absolute file paths to recurse
into them.
The output of this tool is a list of suggestions in Vim quickfix format,
which is accepted by lots of different editors.
## Purpose
Golint differs from gofmt. Gofmt reformats Go source code, whereas
golint prints out style mistakes.
Golint differs from govet. Govet is concerned with correctness, whereas
golint is concerned with coding style. Golint is in use at Google, and it
seeks to match the accepted style of the open source Go project.
The suggestions made by golint are exactly that: suggestions.
Golint is not perfect, and has both false positives and false negatives.
Do not treat its output as a gold standard. We will not be adding pragmas
or other knobs to suppress specific warnings, so do not expect or require
code to be completely "lint-free".
In short, this tool is not, and will never be, trustworthy enough for its
suggestions to be enforced automatically, for example as part of a build process.
Golint makes suggestions for many of the mechanically checkable items listed in
[Effective Go](https://golang.org/doc/effective_go.html) and the
[CodeReviewComments wiki page](https://golang.org/wiki/CodeReviewComments).
## Scope
Golint is meant to carry out the stylistic conventions put forth in
[Effective Go](https://golang.org/doc/effective_go.html) and
[CodeReviewComments](https://golang.org/wiki/CodeReviewComments).
Changes that are not aligned with those documents will not be considered.
## Contributions
Contributions to this project are welcome provided they are [in scope](#scope),
though please send mail before starting work on anything major.
Contributors retain their copyright, so we need you to fill out
[a short form](https://developers.google.com/open-source/cla/individual)
before we can accept your contribution.
## Vim
Add this to your ~/.vimrc:
set rtp+=$GOPATH/src/golang.org/x/lint/misc/vim
If you have multiple entries in your GOPATH, replace `$GOPATH` with the right value.
Running `:Lint` will run golint on the current file and populate the quickfix list.
Optionally, add this to your `~/.vimrc` to automatically run `golint` on `:w`
autocmd BufWritePost,FileWritePost *.go execute 'Lint' | cwindow
## Emacs
Add this to your `.emacs` file:
(add-to-list 'load-path (concat (getenv "GOPATH") "/src/golang.org/x/lint/misc/emacs/"))
(require 'golint)
If you have multiple entries in your GOPATH, replace `$GOPATH` with the right value.
Running M-x golint will run golint on the current file.
For more usage, see [Compilation-Mode](http://www.gnu.org/software/emacs/manual/html_node/emacs/Compilation-Mode.html).

// Package gcexportdata provides functions for locating, reading, and
// writing export data files containing type information produced by the
// gc compiler. This package supports go1.7 export data format and all
// later versions.
//
// Although it might seem convenient for this package to live alongside
// go/types in the standard library, this would cause version skew
// problems for developer tools that use it, since they must be able to
// consume the outputs of the gc compiler both before and after a Go
// update such as from Go 1.7 to Go 1.8. Because this package lives in
// golang.org/x/tools, sites can update their version of this repo some
// time before the Go 1.8 release and rebuild and redeploy their
// developer tools, which will then be able to consume both Go 1.7 and
// Go 1.8 export data files, so they will work before and after the
// Go update. (See discussion at https://golang.org/issue/15651.)

Package packages loads Go packages for inspection and analysis.
The Load function takes as input a list of patterns and return a list of Package
structs describing individual packages matched by those patterns.
The LoadMode controls the amount of detail in the loaded packages.
Load passes most patterns directly to the underlying build tool,
but all patterns with the prefix "query=", where query is a
non-empty string of letters from [a-z], are reserved and may be
interpreted as query operators.
Two query operators are currently supported: "file" and "pattern".
The query "file=path/to/file.go" matches the package or packages enclosing
the Go source file path/to/file.go. For example "file=~/go/src/fmt/print.go"
might return the packages "fmt" and "fmt [fmt.test]".
The query "pattern=string" causes "string" to be passed directly to
the underlying build tool. In most cases this is unnecessary,
but an application can use Load("pattern=" + x) as an escaping mechanism
to ensure that x is not interpreted as a query operator if it contains '='.
All other query operators are reserved for future use and currently
cause Load to report an error.
The Package struct provides basic information about the package, including
- ID, a unique identifier for the package in the returned set;
- GoFiles, the names of the package's Go source files;
- Imports, a map from source import strings to the Packages they name;
- Types, the type information for the package's exported symbols;
- Syntax, the parsed syntax trees for the package's source code; and
- TypeInfo, the result of a complete type-check of the package syntax trees.
(See the documentation for type Package for the complete list of fields
and more detailed descriptions.)
For example,
Load(nil, "bytes", "unicode...")
returns four Package structs describing the standard library packages
bytes, unicode, unicode/utf16, and unicode/utf8. Note that one pattern
can match multiple packages and that a package might be matched by
multiple patterns: in general it is not possible to determine which
packages correspond to which patterns.
Note that the list returned by Load contains only the packages matched
by the patterns. Their dependencies can be found by walking the import
graph using the Imports fields.
The Load function can be configured by passing a pointer to a Config as
the first argument. A nil Config is equivalent to the zero Config, which
causes Load to run in LoadFiles mode, collecting minimal information.
See the documentation for type Config for details.
As noted earlier, the Config.Mode controls the amount of detail
reported about the loaded packages. See the documentation for type LoadMode
for details.
Most tools should pass their command-line arguments (after any flags)
uninterpreted to the loader, so that the loader can interpret them
according to the conventions of the underlying build system.
See the Example function for typical usage.

/*
Motivation and design considerations
The new package's design solves problems addressed by two existing
packages: go/build, which locates and describes packages, and
golang.org/x/tools/go/loader, which loads, parses and type-checks them.
The go/build.Package structure encodes too much of the 'go build' way
of organizing projects, leaving us in need of a data type that describes a
package of Go source code independent of the underlying build system.
We wanted something that works equally well with go build and vgo, and
also other build systems such as Bazel and Blaze, making it possible to
construct analysis tools that work in all these environments.
Tools such as errcheck and staticcheck were essentially unavailable to
the Go community at Google, and some of Google's internal tools for Go
are unavailable externally.
This new package provides a uniform way to obtain package metadata by
querying each of these build systems, optionally supporting their
preferred command-line notations for packages, so that tools integrate
neatly with users' build environments. The Metadata query function
executes an external query tool appropriate to the current workspace.
Loading packages always returns the complete import graph "all the way down",
even if all you want is information about a single package, because the query
mechanisms of all the build systems we currently support ({go,vgo} list, and
blaze/bazel aspect-based query) cannot provide detailed information
about one package without visiting all its dependencies too, so there is
no additional asymptotic cost to providing transitive information.
(This property might not be true of a hypothetical 5th build system.)
In calls to TypeCheck, all initial packages, and any package that
transitively depends on one of them, must be loaded from source.
Consider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from
source; D may be loaded from export data, and E may not be loaded at all
(though it's possible that D's export data mentions it, so a
types.Package may be created for it and exposed.)
The old loader had a feature to suppress type-checking of function
bodies on a per-package basis, primarily intended to reduce the work of
obtaining type information for imported packages. Now that imports are
satisfied by export data, the optimization no longer seems necessary.
Despite some early attempts, the old loader did not exploit export data,
instead always using the equivalent of WholeProgram mode. This was due
to the complexity of mixing source and export data packages (now
resolved by the upward traversal mentioned above), and because export data
files were nearly always missing or stale. Now that 'go build' supports
caching, all the underlying build systems can guarantee to produce
export data in a reasonable (amortized) time.
Test "main" packages synthesized by the build system are now reported as
first-class packages, avoiding the need for clients (such as go/ssa) to
reinvent this generation logic.
One way in which go/packages is simpler than the old loader is in its
treatment of in-package tests. In-package tests are packages that
consist of all the files of the library under test, plus the test files.
The old loader constructed in-package tests by a two-phase process of
mutation called "augmentation": first it would construct and type check
all the ordinary library packages and type-check the packages that
depend on them; then it would add more (test) files to the package and
type-check again. This two-phase approach had four major problems:
1) in processing the tests, the loader modified the library package,
leaving no way for a client application to see both the test
package and the library package; one would mutate into the other.
2) because test files can declare additional methods on types defined in
the library portion of the package, the dispatch of method calls in
the library portion was affected by the presence of the test files.
This should have been a clue that the packages were logically
different.
3) this model of "augmentation" assumed at most one in-package test
per library package, which is true of projects using 'go build',
but not other build systems.
4) because of the two-phase nature of test processing, all packages that
import the library package had to be processed before augmentation,
forcing a "one-shot" API and preventing the client from calling Load
in several times in sequence as is now possible in WholeProgram mode.
(TypeCheck mode has a similar one-shot restriction for a different reason.)
Early drafts of this package supported "multi-shot" operation.
Although it allowed clients to make a sequence of calls (or concurrent
calls) to Load, building up the graph of Packages incrementally,
it was of marginal value: it complicated the API
(since it allowed some options to vary across calls but not others),
it complicated the implementation,
it cannot be made to work in Types mode, as explained above,
and it was less efficient than making one combined call (when this is possible).
Among the clients we have inspected, none made multiple calls to load
but could not be easily and satisfactorily modified to make only a single call.
However, applications changes may be required.
For example, the ssadump command loads the user-specified packages
and in addition the runtime package. It is tempting to simply append
"runtime" to the user-provided list, but that does not work if the user
specified an ad-hoc package such as [a.go b.go].
Instead, ssadump no longer requests the runtime package,
but seeks it among the dependencies of the user-specified packages,
and emits an error if it is not found.
Overlays: The Overlay field in the Config allows providing alternate contents
for Go source files, by providing a mapping from file path to contents.
go/packages will pull in new imports added in overlay files when go/packages
is run in LoadImports mode or greater.
Overlay support for the go list driver isn't complete yet: if the file doesn't
exist on disk, it will only be recognized in an overlay if it is a non-test file
and the package would be reported even without the overlay.
Questions & Tasks
- Add GOARCH/GOOS?
They are not portable concepts, but could be made portable.
Our goal has been to allow users to express themselves using the conventions
of the underlying build system: if the build system honors GOARCH
during a build and during a metadata query, then so should
applications built atop that query mechanism.
Conversely, if the target architecture of the build is determined by
command-line flags, the application can pass the relevant
flags through to the build system using a command such as:
myapp -query_flag="--cpu=amd64" -query_flag="--os=darwin"
However, this approach is low-level, unwieldy, and non-portable.
GOOS and GOARCH seem important enough to warrant a dedicated option.
- How should we handle partial failures such as a mixture of good and
malformed patterns, existing and non-existent packages, successful and
failed builds, import failures, import cycles, and so on, in a call to
Load?
- Support bazel, blaze, and go1.10 list, not just go1.11 list.
- Handle (and test) various partial success cases, e.g.
a mixture of good packages and:
invalid patterns
nonexistent packages
empty packages
packages with malformed package or import declarations
unreadable files
import cycles
other parse errors
type errors
Make sure we record errors at the correct place in the graph.
- Missing packages among initial arguments are not reported.
Return bogus packages for them, like golist does.
- "undeclared name" errors (for example) are reported out of source file
order. I suspect this is due to the breadth-first resolution now used
by go/types. Is that a bug? Discuss with gri.

// ./vendor or ./mycode/vendor, but ./vendor/... and ./mycode/vendor/... do.
