A FileSystem Abstraction System for Go
[![Build Status](https://travis-ci.org/spf13/afero.svg)](https://travis-ci.org/spf13/afero) [![Build status](https://ci.appveyor.com/api/projects/status/github/spf13/afero?branch=master&svg=true)](https://ci.appveyor.com/project/spf13/afero) [![GoDoc](https://godoc.org/github.com/spf13/afero?status.svg)](https://godoc.org/github.com/spf13/afero) [![Join the chat at https://gitter.im/spf13/afero](https://badges.gitter.im/Dev%20Chat.svg)](https://gitter.im/spf13/afero?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
# Overview
Afero is a filesystem framework providing a simple, uniform and universal API
interacting with any filesystem, as an abstraction layer providing interfaces,
types and methods. Afero has an exceptionally clean interface and simple design
without needless constructors or initialization methods.
Afero is also a library providing a base set of interoperable backend
filesystems that make it easy to work with afero while retaining all the power
and benefit of the os and ioutil packages.
Afero provides significant improvements over using the os package alone, most
notably the ability to create mock and testing filesystems without relying on the disk.
It is suitable for use in any situation where you would consider using the OS
package as it provides an additional abstraction that makes it easy to use a
memory backed file system during testing. It also adds support for the http
filesystem for full interoperability.
## Afero Features
* A single consistent API for accessing a variety of filesystems
* Interoperation between a variety of file system types
* A set of interfaces to encourage and enforce interoperability between backends
* An atomic cross platform memory backed file system
* Support for compositional (union) file systems by combining multiple file systems acting as one
* Specialized backends which modify existing filesystems (Read Only, Regexp filtered)
* A set of utility functions ported from io, ioutil & hugo to be afero aware
* Wrapper for go 1.16 filesystem abstraction `io/fs.FS`
# Using Afero
Afero is easy to use and easier to adopt.
A few different ways you could use Afero:
* Use the interfaces alone to define your own file system.
* Wrapper for the OS packages.
* Define different filesystems for different parts of your application.
* Use Afero for mock filesystems while testing
## Step 1: Install Afero
First use go get to install the latest version of the library.
$ go get github.com/spf13/afero
Next include Afero in your application.
```go
import "github.com/spf13/afero"
```
## Step 2: Declare a backend
First define a package variable and set it to a pointer to a filesystem.
```go
var AppFs = afero.NewMemMapFs()
or
var AppFs = afero.NewOsFs()
```
It is important to note that if you repeat the composite literal you
will be using a completely new and isolated filesystem. In the case of
OsFs it will still use the same underlying filesystem but will reduce
the ability to drop in other filesystems as desired.
## Step 3: Use it like you would the OS package
Throughout your application use any function and method like you normally
would.
So if my application before had:
```go
os.Open("/tmp/foo")
```
We would replace it with:
```go
AppFs.Open("/tmp/foo")
```
`AppFs` being the variable we defined above.
## List of all available functions

In some applications it may make sense to define a new package that
simply exports the file system variable for easy access from anywhere.
## Using Afero's utility functions
Afero provides a set of functions to make it easier to use the underlying file systems.
These functions have been primarily ported from io & ioutil with some developed for Hugo.
The afero utilities support all afero compatible backends.
The list of utilities includes:
```go
DirExists(path string) (bool, error)
Exists(path string) (bool, error)
FileContainsBytes(filename string, subslice []byte) (bool, error)
GetTempDir(subPath string) string
IsDir(path string) (bool, error)
IsEmpty(path string) (bool, error)
ReadDir(dirname string) ([]os.FileInfo, error)
ReadFile(filename string) ([]byte, error)
SafeWriteReader(path string, r io.Reader) (err error)
TempDir(dir, prefix string) (name string, err error)
TempFile(dir, prefix string) (f File, err error)
Walk(root string, walkFn filepath.WalkFunc) error
WriteFile(filename string, data []byte, perm os.FileMode) error
WriteReader(path string, r io.Reader) (err error)
```
For a complete list see [Afero's GoDoc](https://godoc.org/github.com/spf13/afero)
They are available under two different approaches to use. You can either call
them directly where the first parameter of each function will be the file
system, or you can declare a new `Afero`, a custom type used to bind these
functions as methods to a given filesystem.
### Calling utilities directly
```go
fs := new(afero.MemMapFs)
f, err := afero.TempFile(fs,"", "ioutil-test")
```
### Calling via Afero
```go
fs := afero.NewMemMapFs()
afs := &afero.Afero{Fs: fs}
f, err := afs.TempFile("", "ioutil-test")
```
## Using Afero for Testing
There is a large benefit to using a mock filesystem for testing. It has a
completely blank state every time it is initialized and can be easily
reproducible regardless of OS. You could create files to your heart’s content
and the file access would be fast while also saving you from all the annoying
issues with deleting temporary files, Windows file locking, etc. The MemMapFs
backend is perfect for testing.
* Much faster than performing I/O operations on disk
* Avoid security issues and permissions
* Far more control. 'rm -rf /' with confidence
* Test setup is far more easier to do
* No test cleanup needed
One way to accomplish this is to define a variable as mentioned above.
In your application this will be set to afero.NewOsFs() during testing you
can set it to afero.NewMemMapFs().
It wouldn't be uncommon to have each test initialize a blank slate memory
backend. To do this I would define my `appFS = afero.NewOsFs()` somewhere
appropriate in my application code. This approach ensures that Tests are order
independent, with no test relying on the state left by an earlier test.
Then in my tests I would initialize a new MemMapFs for each test:
```go
func TestExist(t *testing.T) {
appFS := afero.NewMemMapFs()
// create test files and directories
appFS.MkdirAll("src/a", 0755)
afero.WriteFile(appFS, "src/a/b", []byte("file b"), 0644)
afero.WriteFile(appFS, "src/c", []byte("file c"), 0644)
name := "src/c"
_, err := appFS.Stat(name)
if os.IsNotExist(err) {
t.Errorf("file \"%s\" does not exist.\n", name)
}
}
```
# Available Backends
## Operating System Native
### OsFs
The first is simply a wrapper around the native OS calls. This makes it
very easy to use as all of the calls are the same as the existing OS
calls. It also makes it trivial to have your code use the OS during
operation and a mock filesystem during testing or as needed.
```go
appfs := afero.NewOsFs()
appfs.MkdirAll("src/a", 0755)
```
## Memory Backed Storage
### MemMapFs
Afero also provides a fully atomic memory backed filesystem perfect for use in
mocking and to speed up unnecessary disk io when persistence isn’t
necessary. It is fully concurrent and will work within go routines
safely.
```go
mm := afero.NewMemMapFs()
mm.MkdirAll("src/a", 0755)
```
#### InMemoryFile
As part of MemMapFs, Afero also provides an atomic, fully concurrent memory
backed file implementation. This can be used in other memory backed file
systems with ease. Plans are to add a radix tree memory stored file
system using InMemoryFile.
## Network Interfaces
### SftpFs
Afero has experimental support for secure file transfer protocol (sftp). Which can
be used to perform file operations over a encrypted channel.
### GCSFs
Afero has experimental support for Google Cloud Storage (GCS). You can either set the
`GOOGLE_APPLICATION_CREDENTIALS_JSON` env variable to your JSON credentials or use `opts` in
`NewGcsFS` to configure access to your GCS bucket.
Some known limitations of the existing implementation:
* No Chmod support - The GCS ACL could probably be mapped to *nix style permissions but that would add another level of complexity and is ignored in this version.
* No Chtimes support - Could be simulated with attributes (gcs a/m-times are set implicitly) but that's is left for another version.
* Not thread safe - Also assumes all file operations are done through the same instance of the GcsFs. File operations between different GcsFs instances are not guaranteed to be consistent.
## Filtering Backends
### BasePathFs
The BasePathFs restricts all operations to a given path within an Fs.
The given file name to the operations on this Fs will be prepended with
the base path before calling the source Fs.
```go
bp := afero.NewBasePathFs(afero.NewOsFs(), "/base/path")
```
### ReadOnlyFs
A thin wrapper around the source Fs providing a read only view.
```go
fs := afero.NewReadOnlyFs(afero.NewOsFs())
_, err := fs.Create("/file.txt")
// err = syscall.EPERM
```
# RegexpFs
A filtered view on file names, any file NOT matching
the passed regexp will be treated as non-existing.
Files not matching the regexp provided will not be created.
Directories are not filtered.
```go
fs := afero.NewRegexpFs(afero.NewMemMapFs(), regexp.MustCompile(`\.txt$`))
_, err := fs.Create("/file.html")
// err = syscall.ENOENT
```
### HttpFs
Afero provides an http compatible backend which can wrap any of the existing
backends.
The Http package requires a slightly specific version of Open which
returns an http.File type.
Afero provides an httpFs file system which satisfies this requirement.
Any Afero FileSystem can be used as an httpFs.
```go
httpFs := afero.NewHttpFs(<ExistingFS>)
fileserver := http.FileServer(httpFs.Dir(<PATH>))
http.Handle("/", fileserver)
```
## Composite Backends
Afero provides the ability have two filesystems (or more) act as a single
file system.
### CacheOnReadFs
The CacheOnReadFs will lazily make copies of any accessed files from the base
layer into the overlay. Subsequent reads will be pulled from the overlay
directly permitting the request is within the cache duration of when it was
created in the overlay.
If the base filesystem is writeable, any changes to files will be
done first to the base, then to the overlay layer. Write calls to open file
handles like `Write()` or `Truncate()` to the overlay first.
To writing files to the overlay only, you can use the overlay Fs directly (not
via the union Fs).
Cache files in the layer for the given time.Duration, a cache duration of 0
means "forever" meaning the file will not be re-requested from the base ever.
A read-only base will make the overlay also read-only but still copy files
from the base to the overlay when they're not present (or outdated) in the
caching layer.
```go
base := afero.NewOsFs()
layer := afero.NewMemMapFs()
ufs := afero.NewCacheOnReadFs(base, layer, 100 * time.Second)
```
### CopyOnWriteFs()
The CopyOnWriteFs is a read only base file system with a potentially
writeable layer on top.
Read operations will first look in the overlay and if not found there, will
serve the file from the base.
Changes to the file system will only be made in the overlay.
Any attempt to modify a file found only in the base will copy the file to the
overlay layer before modification (including opening a file with a writable
handle).
Removing and Renaming files present only in the base layer is not currently
permitted. If a file is present in the base layer and the overlay, only the
overlay will be removed/renamed.
```go
base := afero.NewOsFs()
roBase := afero.NewReadOnlyFs(base)
ufs := afero.NewCopyOnWriteFs(roBase, afero.NewMemMapFs())
fh, _ = ufs.Create("/home/test/file2.txt")
fh.WriteString("This is a test")
fh.Close()
```
In this example all write operations will only occur in memory (MemMapFs)
leaving the base filesystem (OsFs) untouched.
## Desired/possible backends
The following is a short list of possible backends we hope someone will
implement:
* SSH
* S3
# About the project
## What's in the name
Afero comes from the latin roots Ad-Facere.
**"Ad"** is a prefix meaning "to".
**"Facere"** is a form of the root "faciō" making "make or do".
The literal meaning of afero is "to make" or "to do" which seems very fitting
for a library that allows one to make files and directories and do things with them.
The English word that shares the same roots as Afero is "affair". Affair shares
the same concept but as a noun it means "something that is made or done" or "an
object of a particular type".
It's also nice that unlike some of my other libraries (hugo, cobra, viper) it
Googles very well.

// This file contains Form-specific logic and wrappers for data in tables.go.
// Rune info is stored in a separate trie per composing form. A composing form
// and its corresponding decomposing form share the same trie. Each trie maps
// a rune to a uint16. The values take two forms. For v >= 0x8000:
// bits
// 15: 1 (inverse of NFD_QC bit of qcInfo)
// 13..7: qcInfo (see below). isYesD is always true (no decompostion).
// 6..0: ccc (compressed CCC value).
// For v < 0x8000, the respective rune has a decomposition and v is an index
// into a byte array of UTF-8 decomposition sequences and additional info and
// has the form:
// <header> <decomp_byte>* [<tccc> [<lccc>]]
// The header contains the number of bytes in the decomposition (excluding this
// length byte). The two most significant bits of this length byte correspond
// to bit 5 and 4 of qcInfo (see below). The byte sequence itself starts at v+1.
// The byte sequence is followed by a trailing and leading CCC if the values
// for these are not zero. The value of v determines which ccc are appended
// to the sequences. For v < firstCCC, there are none, for v >= firstCCC,
// the sequence is followed by a trailing ccc, and for v >= firstLeadingCC
// there is an additional leading ccc. The value of tccc itself is the
// trailing CCC shifted left 2 bits. The two least-significant bits of tccc

//
// The Timestamp message represents a timestamp,
// an instant in time since the Unix epoch (January 1st, 1970).
//
//
// Conversion to a Go Time
//
// The AsTime method can be used to convert a Timestamp message to a
// standard Go time.Time value in UTC:
//
// t := ts.AsTime()
// ... // make use of t as a time.Time
//
// Converting to a time.Time is a common operation so that the extensive
// set of time-based operations provided by the time package can be leveraged.
// See https://golang.org/pkg/time for more information.
//
// The AsTime method performs the conversion on a best-effort basis. Timestamps
// with denormal values (e.g., nanoseconds beyond 0 and 99999999, inclusive)
// are normalized during the conversion to a time.Time. To manually check for
// invalid Timestamps per the documented limitations in timestamp.proto,
// additionally call the CheckValid method:
//
// if err := ts.CheckValid(); err != nil {
// ... // handle error
// }
//
//
// Conversion from a Go Time
//
// The timestamppb.New function can be used to construct a Timestamp message
// from a standard Go time.Time value:
//
// ts := timestamppb.New(t)
// ... // make use of ts as a *timestamppb.Timestamp
//
// In order to construct a Timestamp representing the current time, use Now:
//
// ts := timestamppb.Now()
// ... // make use of ts as a *timestamppb.Timestamp
//

// A Timestamp represents a point in time independent of any time zone or local
// calendar, encoded as a count of seconds and fractions of seconds at
// nanosecond resolution. The count is relative to an epoch at UTC midnight on
// January 1, 1970, in the proleptic Gregorian calendar which extends the
// Gregorian calendar backwards to year one.
//
// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
// second table is needed for interpretation, using a [24-hour linear
// smear](https://developers.google.com/time/smear).
//
// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
// restricting to that range, we ensure that we can convert to and from [RFC
// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
//
// # Examples
//
// Example 1: Compute Timestamp from POSIX `time()`.
//
// Timestamp timestamp;
// timestamp.set_seconds(time(NULL));
// timestamp.set_nanos(0);
//
// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
//
// struct timeval tv;
// gettimeofday(&tv, NULL);
//
// Timestamp timestamp;
// timestamp.set_seconds(tv.tv_sec);
// timestamp.set_nanos(tv.tv_usec * 1000);
//
// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
//
// FILETIME ft;
// GetSystemTimeAsFileTime(&ft);
// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
//
// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
// Timestamp timestamp;
// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
//
// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
//
// long millis = System.currentTimeMillis();
//
// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
// .setNanos((int) ((millis % 1000) * 1000000)).build();
//
//
// Example 5: Compute Timestamp from Java `Instant.now()`.
//
// Instant now = Instant.now();
//
// Timestamp timestamp =
// Timestamp.newBuilder().setSeconds(now.getEpochSecond())
// .setNanos(now.getNano()).build();
//
//
// Example 6: Compute Timestamp from current time in Python.
//
// timestamp = Timestamp()
// timestamp.GetCurrentTime()
//
// # JSON Mapping
//
// In JSON format, the Timestamp type is encoded as a string in the
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
// where {year} is always expressed using four digits while {month}, {day},
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
// is required. A proto3 JSON serializer should always use UTC (as indicated by
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
// able to accept both UTC and other timezones (as indicated by an offset).
//
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
// 01:30 UTC on January 15, 2017.
//
// In JavaScript, one can convert a Date object to this format using the
// standard
// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
// method. In Python, a standard `datetime.datetime` object can be converted
// to this format using
// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
// the Joda Time's [`ISODateTimeFormat.dateTime()`](
// http://www.joda.org/joda-time/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime%2D%2D
// ) to obtain a formatter capable of generating timestamps in this format.
