-# redistore
-
-[![Build Status](https://drone.io/github.com/boj/redistore/status.png)](https://drone.io/github.com/boj/redistore/latest)
-
-A session store backend for [gorilla/sessions](http://www.gorillatoolkit.org/pkg/sessions) - [src](https://github.com/gorilla/sessions).
-
-## Requirements
-
-Depends on the [Redigo](https://github.com/garyburd/redigo) Redis library.
-
-## Installation
-
- go get gopkg.in/boj/redistore.v1
-
-## Documentation
-
-Available on [godoc.org](http://www.godoc.org/gopkg.in/boj/redistore.v1).
-
-See http://www.gorillatoolkit.org/pkg/sessions for full documentation on underlying interface.
-
-### Example
-
- // Fetch new store.
- store, err := NewRediStore(10, "tcp", ":6379", "", []byte("secret-key"))
- if err != nil {
- panic(err)
- }
- defer store.Close()
-
- // Get a session.
- session, err = store.Get(req, "session-key")
- if err != nil {
- log.Error(err.Error())
- }
-
- // Add a value.
- session.Values["foo"] = "bar"
-
- // Save.
- if err = sessions.Save(req, rsp); err != nil {
- t.Fatalf("Error saving session: %v", err)
- }
-
- // Delete session.
- session.Options.MaxAge = -1
- if err = sessions.Save(req, rsp); err != nil {
- t.Fatalf("Error saving session: %v", err)
- }
-
- // Change session storage configuration for MaxAge = 10 days.
- store.SetMaxAge(10*24*3600)

-Bolt [![Coverage Status](https://coveralls.io/repos/boltdb/bolt/badge.svg?branch=master)](https://coveralls.io/r/boltdb/bolt?branch=master) [![GoDoc](https://godoc.org/github.com/boltdb/bolt?status.svg)](https://godoc.org/github.com/boltdb/bolt) ![Version](https://img.shields.io/badge/version-1.2.1-green.svg)
-====
-
-Bolt is a pure Go key/value store inspired by [Howard Chu's][hyc_symas]
-[LMDB project][lmdb]. The goal of the project is to provide a simple,
-fast, and reliable database for projects that don't require a full database
-server such as Postgres or MySQL.
-
-Since Bolt is meant to be used as such a low-level piece of functionality,
-simplicity is key. The API will be small and only focus on getting values
-and setting values. That's it.
-
-[hyc_symas]: https://twitter.com/hyc_symas
-[lmdb]: http://symas.com/mdb/
-
-## Project Status
-
-Bolt is stable, the API is fixed, and the file format is fixed. Full unit
-test coverage and randomized black box testing are used to ensure database
-consistency and thread safety. Bolt is currently used in high-load production
-environments serving databases as large as 1TB. Many companies such as
-Shopify and Heroku use Bolt-backed services every day.

-
-## Getting Started
-
-### Installing
-
-To start using Bolt, install Go and run `go get`:
-
-```sh
-$ go get github.com/boltdb/bolt/...
-```
-
-This will retrieve the library and install the `bolt` command line utility into
-your `$GOBIN` path.
-
-
-### Opening a database
-
-The top-level object in Bolt is a `DB`. It is represented as a single file on
-your disk and represents a consistent snapshot of your data.
-
-To open your database, simply use the `bolt.Open()` function:
-
-```go
-package main
-
-import (
- "log"
-
- "github.com/boltdb/bolt"
-)
-
-func main() {
- // Open the my.db data file in your current directory.
- // It will be created if it doesn't exist.
- db, err := bolt.Open("my.db", 0600, nil)
- if err != nil {
- log.Fatal(err)
- }
- defer db.Close()
-
- ...
-}
-```
-
-Please note that Bolt obtains a file lock on the data file so multiple processes
-cannot open the same database at the same time. Opening an already open Bolt
-database will cause it to hang until the other process closes it. To prevent
-an indefinite wait you can pass a timeout option to the `Open()` function:
-
-```go
-db, err := bolt.Open("my.db", 0600, &bolt.Options{Timeout: 1 * time.Second})
-```
-
-
-### Transactions
-
-Bolt allows only one read-write transaction at a time but allows as many
-read-only transactions as you want at a time. Each transaction has a consistent
-view of the data as it existed when the transaction started.
-
-Individual transactions and all objects created from them (e.g. buckets, keys)
-are not thread safe. To work with data in multiple goroutines you must start
-a transaction for each one or use locking to ensure only one goroutine accesses
-a transaction at a time. Creating transaction from the `DB` is thread safe.
-
-Read-only transactions and read-write transactions should not depend on one
-another and generally shouldn't be opened simultaneously in the same goroutine.
-This can cause a deadlock as the read-write transaction needs to periodically
-re-map the data file but it cannot do so while a read-only transaction is open.
-
-
-#### Read-write transactions
-
-To start a read-write transaction, you can use the `DB.Update()` function:
-
-```go
-err := db.Update(func(tx *bolt.Tx) error {
- ...
- return nil
-})
-```
-
-Inside the closure, you have a consistent view of the database. You commit the
-transaction by returning `nil` at the end. You can also rollback the transaction
-at any point by returning an error. All database operations are allowed inside
-a read-write transaction.
-
-Always check the return error as it will report any disk failures that can cause
-your transaction to not complete. If you return an error within your closure
-it will be passed through.
-
-
-#### Read-only transactions
-
-To start a read-only transaction, you can use the `DB.View()` function:
-
-```go
-err := db.View(func(tx *bolt.Tx) error {
- ...
- return nil
-})
-```
-
-You also get a consistent view of the database within this closure, however,
-no mutating operations are allowed within a read-only transaction. You can only
-retrieve buckets, retrieve values, and copy the database within a read-only
-transaction.
-
-
-#### Batch read-write transactions
-
-Each `DB.Update()` waits for disk to commit the writes. This overhead
-can be minimized by combining multiple updates with the `DB.Batch()`
-function:
-
-```go
-err := db.Batch(func(tx *bolt.Tx) error {
- ...
- return nil
-})
-```
-
-Concurrent Batch calls are opportunistically combined into larger
-transactions. Batch is only useful when there are multiple goroutines
-calling it.
-
-The trade-off is that `Batch` can call the given
-function multiple times, if parts of the transaction fail. The
-function must be idempotent and side effects must take effect only
-after a successful return from `DB.Batch()`.
-
-For example: don't display messages from inside the function, instead
-set variables in the enclosing scope:
-
-```go
-var id uint64
-err := db.Batch(func(tx *bolt.Tx) error {
- // Find last key in bucket, decode as bigendian uint64, increment
- // by one, encode back to []byte, and add new key.
- ...
- id = newValue
- return nil
-})
-if err != nil {
- return ...
-}
-fmt.Println("Allocated ID %d", id)
-```
-
-
-#### Managing transactions manually
-
-The `DB.View()` and `DB.Update()` functions are wrappers around the `DB.Begin()`
-function. These helper functions will start the transaction, execute a function,
-and then safely close your transaction if an error is returned. This is the
-recommended way to use Bolt transactions.
-
-However, sometimes you may want to manually start and end your transactions.
-You can use the `DB.Begin()` function directly but **please** be sure to close
-the transaction.
-
-```go
-// Start a writable transaction.
-tx, err := db.Begin(true)
-if err != nil {
- return err
-}
-defer tx.Rollback()
-
-// Use the transaction...
-_, err := tx.CreateBucket([]byte("MyBucket"))
-if err != nil {
- return err
-}
-
-// Commit the transaction and check for error.
-if err := tx.Commit(); err != nil {
- return err
-}
-```
-
-The first argument to `DB.Begin()` is a boolean stating if the transaction
-should be writable.
-
-
-### Using buckets
-
-Buckets are collections of key/value pairs within the database. All keys in a
-bucket must be unique. You can create a bucket using the `DB.CreateBucket()`
-function:
-
-```go
-db.Update(func(tx *bolt.Tx) error {
- b, err := tx.CreateBucket([]byte("MyBucket"))
- if err != nil {
- return fmt.Errorf("create bucket: %s", err)
- }
- return nil
-})
-```
-
-You can also create a bucket only if it doesn't exist by using the
-`Tx.CreateBucketIfNotExists()` function. It's a common pattern to call this
-function for all your top-level buckets after you open your database so you can
-guarantee that they exist for future transactions.
-
-To delete a bucket, simply call the `Tx.DeleteBucket()` function.
-
-
-### Using key/value pairs
-
-To save a key/value pair to a bucket, use the `Bucket.Put()` function:
-
-```go
-db.Update(func(tx *bolt.Tx) error {
- b := tx.Bucket([]byte("MyBucket"))
- err := b.Put([]byte("answer"), []byte("42"))
- return err
-})
-```
-
-This will set the value of the `"answer"` key to `"42"` in the `MyBucket`
-bucket. To retrieve this value, we can use the `Bucket.Get()` function:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- b := tx.Bucket([]byte("MyBucket"))
- v := b.Get([]byte("answer"))
- fmt.Printf("The answer is: %s\n", v)
- return nil
-})
-```
-
-The `Get()` function does not return an error because its operation is
-guaranteed to work (unless there is some kind of system failure). If the key
-exists then it will return its byte slice value. If it doesn't exist then it
-will return `nil`. It's important to note that you can have a zero-length value
-set to a key which is different than the key not existing.
-
-Use the `Bucket.Delete()` function to delete a key from the bucket.
-
-Please note that values returned from `Get()` are only valid while the
-transaction is open. If you need to use a value outside of the transaction
-then you must use `copy()` to copy it to another byte slice.
-
-
-### Autoincrementing integer for the bucket
-By using the `NextSequence()` function, you can let Bolt determine a sequence
-which can be used as the unique identifier for your key/value pairs. See the
-example below.
-
-```go
-// CreateUser saves u to the store. The new user ID is set on u once the data is persisted.
-func (s *Store) CreateUser(u *User) error {
- return s.db.Update(func(tx *bolt.Tx) error {
- // Retrieve the users bucket.
- // This should be created when the DB is first opened.
- b := tx.Bucket([]byte("users"))
-
- // Generate ID for the user.
- // This returns an error only if the Tx is closed or not writeable.
- // That can't happen in an Update() call so I ignore the error check.
- id, _ := b.NextSequence()
- u.ID = int(id)
-
- // Marshal user data into bytes.
- buf, err := json.Marshal(u)
- if err != nil {
- return err
- }
-
- // Persist bytes to users bucket.
- return b.Put(itob(u.ID), buf)
- })
-}
-
-// itob returns an 8-byte big endian representation of v.
-func itob(v int) []byte {
- b := make([]byte, 8)
- binary.BigEndian.PutUint64(b, uint64(v))
- return b
-}
-
-type User struct {
- ID int
- ...
-}
-```
-
-### Iterating over keys
-
-Bolt stores its keys in byte-sorted order within a bucket. This makes sequential
-iteration over these keys extremely fast. To iterate over keys we'll use a
-`Cursor`:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume bucket exists and has keys
- b := tx.Bucket([]byte("MyBucket"))
-
- c := b.Cursor()
-
- for k, v := c.First(); k != nil; k, v = c.Next() {
- fmt.Printf("key=%s, value=%s\n", k, v)
- }
-
- return nil
-})
-```
-
-The cursor allows you to move to a specific point in the list of keys and move
-forward or backward through the keys one at a time.
-
-The following functions are available on the cursor:
-
-```
-First() Move to the first key.
-Last() Move to the last key.
-Seek() Move to a specific key.
-Next() Move to the next key.
-Prev() Move to the previous key.
-```
-
-Each of those functions has a return signature of `(key []byte, value []byte)`.
-When you have iterated to the end of the cursor then `Next()` will return a
-`nil` key. You must seek to a position using `First()`, `Last()`, or `Seek()`
-before calling `Next()` or `Prev()`. If you do not seek to a position then
-these functions will return a `nil` key.
-
-During iteration, if the key is non-`nil` but the value is `nil`, that means
-the key refers to a bucket rather than a value. Use `Bucket.Bucket()` to
-access the sub-bucket.
-
-
-#### Prefix scans
-
-To iterate over a key prefix, you can combine `Seek()` and `bytes.HasPrefix()`:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume bucket exists and has keys
- c := tx.Bucket([]byte("MyBucket")).Cursor()
-
- prefix := []byte("1234")
- for k, v := c.Seek(prefix); k != nil && bytes.HasPrefix(k, prefix); k, v = c.Next() {
- fmt.Printf("key=%s, value=%s\n", k, v)
- }
-
- return nil
-})
-```
-
-#### Range scans
-
-Another common use case is scanning over a range such as a time range. If you
-use a sortable time encoding such as RFC3339 then you can query a specific
-date range like this:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume our events bucket exists and has RFC3339 encoded time keys.
- c := tx.Bucket([]byte("Events")).Cursor()
-
- // Our time range spans the 90's decade.
- min := []byte("1990-01-01T00:00:00Z")
- max := []byte("2000-01-01T00:00:00Z")
-
- // Iterate over the 90's.
- for k, v := c.Seek(min); k != nil && bytes.Compare(k, max) <= 0; k, v = c.Next() {
- fmt.Printf("%s: %s\n", k, v)
- }
-
- return nil
-})
-```
-
-Note that, while RFC3339 is sortable, the Golang implementation of RFC3339Nano does not use a fixed number of digits after the decimal point and is therefore not sortable.
-
-
-#### ForEach()
-
-You can also use the function `ForEach()` if you know you'll be iterating over
-all the keys in a bucket:
-
-```go
-db.View(func(tx *bolt.Tx) error {
- // Assume bucket exists and has keys
- b := tx.Bucket([]byte("MyBucket"))
-
- b.ForEach(func(k, v []byte) error {
- fmt.Printf("key=%s, value=%s\n", k, v)
- return nil
- })
- return nil
-})
-```
-
-Please note that keys and values in `ForEach()` are only valid while
-the transaction is open. If you need to use a key or value outside of
-the transaction, you must use `copy()` to copy it to another byte
-slice.
-
-### Nested buckets
-
-You can also store a bucket in a key to create nested buckets. The API is the
-same as the bucket management API on the `DB` object:
-
-```go
-func (*Bucket) CreateBucket(key []byte) (*Bucket, error)
-func (*Bucket) CreateBucketIfNotExists(key []byte) (*Bucket, error)
-func (*Bucket) DeleteBucket(key []byte) error
-```
-
-Say you had a multi-tenant application where the root level bucket was the account bucket. Inside of this bucket was a sequence of accounts which themselves are buckets. And inside the sequence bucket you could have many buckets pertaining to the Account itself (Users, Notes, etc) isolating the information into logical groupings.
-
-```go
-
-// createUser creates a new user in the given account.
-func createUser(accountID int, u *User) error {
- // Start the transaction.
- tx, err := db.Begin(true)
- if err != nil {
- return err
- }
- defer tx.Rollback()
-
- // Retrieve the root bucket for the account.
- // Assume this has already been created when the account was set up.
- root := tx.Bucket([]byte(strconv.FormatUint(accountID, 10)))
-
- // Setup the users bucket.
- bkt, err := root.CreateBucketIfNotExists([]byte("USERS"))
- if err != nil {
- return err
- }
-
- // Generate an ID for the new user.
- userID, err := bkt.NextSequence()
- if err != nil {
- return err
- }
- u.ID = userID
-
- // Marshal and save the encoded user.
- if buf, err := json.Marshal(u); err != nil {
- return err
- } else if err := bkt.Put([]byte(strconv.FormatUint(u.ID, 10)), buf); err != nil {
- return err
- }
-
- // Commit the transaction.
- if err := tx.Commit(); err != nil {
- return err
- }
-
- return nil
-}
-
-```
-
-
-
-
-### Database backups
-
-Bolt is a single file so it's easy to backup. You can use the `Tx.WriteTo()`
-function to write a consistent view of the database to a writer. If you call
-this from a read-only transaction, it will perform a hot backup and not block
-your other database reads and writes.
-
-By default, it will use a regular file handle which will utilize the operating
-system's page cache. See the [`Tx`](https://godoc.org/github.com/boltdb/bolt#Tx)
-documentation for information about optimizing for larger-than-RAM datasets.
-
-One common use case is to backup over HTTP so you can use tools like `cURL` to
-do database backups:
-
-```go
-func BackupHandleFunc(w http.ResponseWriter, req *http.Request) {
- err := db.View(func(tx *bolt.Tx) error {
- w.Header().Set("Content-Type", "application/octet-stream")
- w.Header().Set("Content-Disposition", `attachment; filename="my.db"`)
- w.Header().Set("Content-Length", strconv.Itoa(int(tx.Size())))
- _, err := tx.WriteTo(w)
- return err
- })
- if err != nil {
- http.Error(w, err.Error(), http.StatusInternalServerError)
- }
-}
-```
-
-Then you can backup using this command:
-
-```sh
-$ curl http://localhost/backup > my.db
-```
-
-Or you can open your browser to `http://localhost/backup` and it will download
-automatically.
-
-If you want to backup to another file you can use the `Tx.CopyFile()` helper
-function.
-
-
-### Statistics
-
-The database keeps a running count of many of the internal operations it
-performs so you can better understand what's going on. By grabbing a snapshot
-of these stats at two points in time we can see what operations were performed
-in that time range.
-
-For example, we could start a goroutine to log stats every 10 seconds:
-
-```go
-go func() {
- // Grab the initial stats.
- prev := db.Stats()
-
- for {
- // Wait for 10s.
- time.Sleep(10 * time.Second)
-
- // Grab the current stats and diff them.
- stats := db.Stats()
- diff := stats.Sub(&prev)
-
- // Encode stats to JSON and print to STDERR.
- json.NewEncoder(os.Stderr).Encode(diff)
-
- // Save stats for the next loop.
- prev = stats
- }
-}()
-```
-
-It's also useful to pipe these stats to a service such as statsd for monitoring
-or to provide an HTTP endpoint that will perform a fixed-length sample.
-
-
-### Read-Only Mode
-
-Sometimes it is useful to create a shared, read-only Bolt database. To this,
-set the `Options.ReadOnly` flag when opening your database. Read-only mode
-uses a shared lock to allow multiple processes to read from the database but
-it will block any processes from opening the database in read-write mode.
-
-```go
-db, err := bolt.Open("my.db", 0666, &bolt.Options{ReadOnly: true})
-if err != nil {
- log.Fatal(err)
-}
-```
-
-### Mobile Use (iOS/Android)
-
-Bolt is able to run on mobile devices by leveraging the binding feature of the
-[gomobile](https://github.com/golang/mobile) tool. Create a struct that will
-contain your database logic and a reference to a `*bolt.DB` with a initializing
-constructor that takes in a filepath where the database file will be stored.
-Neither Android nor iOS require extra permissions or cleanup from using this method.
-
-```go
-func NewBoltDB(filepath string) *BoltDB {
- db, err := bolt.Open(filepath+"/demo.db", 0600, nil)
- if err != nil {
- log.Fatal(err)
- }
-
- return &BoltDB{db}
-}
-
-type BoltDB struct {
- db *bolt.DB
- ...
-}
-
-func (b *BoltDB) Path() string {
- return b.db.Path()

-
-## Comparison with other databases
-
-### Postgres, MySQL, & other relational databases
-
-Relational databases structure data into rows and are only accessible through
-the use of SQL. This approach provides flexibility in how you store and query
-your data but also incurs overhead in parsing and planning SQL statements. Bolt
-accesses all data by a byte slice key. This makes Bolt fast to read and write
-data by key but provides no built-in support for joining values together.
-
-Most relational databases (with the exception of SQLite) are standalone servers
-that run separately from your application. This gives your systems
-flexibility to connect multiple application servers to a single database
-server but also adds overhead in serializing and transporting data over the
-network. Bolt runs as a library included in your application so all data access
-has to go through your application's process. This brings data closer to your
-application but limits multi-process access to the data.
-
-
-### LevelDB, RocksDB
-
-LevelDB and its derivatives (RocksDB, HyperLevelDB) are similar to Bolt in that
-they are libraries bundled into the application, however, their underlying
-structure is a log-structured merge-tree (LSM tree). An LSM tree optimizes
-random writes by using a write ahead log and multi-tiered, sorted files called
-SSTables. Bolt uses a B+tree internally and only a single file. Both approaches
-have trade-offs.
-
-If you require a high random write throughput (>10,000 w/sec) or you need to use
-spinning disks then LevelDB could be a good choice. If your application is
-read-heavy or does a lot of range scans then Bolt could be a good choice.
-
-One other important consideration is that LevelDB does not have transactions.
-It supports batch writing of key/values pairs and it supports read snapshots
-but it will not give you the ability to do a compare-and-swap operation safely.
-Bolt supports fully serializable ACID transactions.
-
-
-### LMDB
-
-Bolt was originally a port of LMDB so it is architecturally similar. Both use
-a B+tree, have ACID semantics with fully serializable transactions, and support
-lock-free MVCC using a single writer and multiple readers.
-
-The two projects have somewhat diverged. LMDB heavily focuses on raw performance
-while Bolt has focused on simplicity and ease of use. For example, LMDB allows
-several unsafe actions such as direct writes for the sake of performance. Bolt
-opts to disallow actions which can leave the database in a corrupted state. The
-only exception to this in Bolt is `DB.NoSync`.
-
-There are also a few differences in API. LMDB requires a maximum mmap size when
-opening an `mdb_env` whereas Bolt will handle incremental mmap resizing
-automatically. LMDB overloads the getter and setter functions with multiple
-flags whereas Bolt splits these specialized cases into their own functions.
-
-
-## Caveats & Limitations
-
-It's important to pick the right tool for the job and Bolt is no exception.
-Here are a few things to note when evaluating and using Bolt:
-
-* Bolt is good for read intensive workloads. Sequential write performance is
- also fast but random writes can be slow. You can use `DB.Batch()` or add a
- write-ahead log to help mitigate this issue.
-
-* Bolt uses a B+tree internally so there can be a lot of random page access.
- SSDs provide a significant performance boost over spinning disks.
-
-* Try to avoid long running read transactions. Bolt uses copy-on-write so
- old pages cannot be reclaimed while an old transaction is using them.
-
-* Byte slices returned from Bolt are only valid during a transaction. Once the
- transaction has been committed or rolled back then the memory they point to
- can be reused by a new page or can be unmapped from virtual memory and you'll
- see an `unexpected fault address` panic when accessing it.
-
-* Bolt uses an exclusive write lock on the database file so it cannot be
- shared by multiple processes.
-
-* Be careful when using `Bucket.FillPercent`. Setting a high fill percent for
- buckets that have random inserts will cause your database to have very poor
- page utilization.
-
-* Use larger buckets in general. Smaller buckets causes poor page utilization
- once they become larger than the page size (typically 4KB).
-
-* Bulk loading a lot of random writes into a new bucket can be slow as the
- page will not split until the transaction is committed. Randomly inserting
- more than 100,000 key/value pairs into a single new bucket in a single
- transaction is not advised.
-
-* Bolt uses a memory-mapped file so the underlying operating system handles the
- caching of the data. Typically, the OS will cache as much of the file as it
- can in memory and will release memory as needed to other processes. This means
- that Bolt can show very high memory usage when working with large databases.
- However, this is expected and the OS will release memory as needed. Bolt can
- handle databases much larger than the available physical RAM, provided its
- memory-map fits in the process virtual address space. It may be problematic
- on 32-bits systems.
-
-* The data structures in the Bolt database are memory mapped so the data file
- will be endian specific. This means that you cannot copy a Bolt file from a
- little endian machine to a big endian machine and have it work. For most
- users this is not a concern since most modern CPUs are little endian.
-
-* Because of the way pages are laid out on disk, Bolt cannot truncate data files
- and return free pages back to the disk. Instead, Bolt maintains a free list
- of unused pages within its data file. These free pages can be reused by later
- transactions. This works well for many use cases as databases generally tend
- to grow. However, it's important to note that deleting large chunks of data
- will not allow you to reclaim that space on disk.

-## Reading the Source
-
-Bolt is a relatively small code base (<3KLOC) for an embedded, serializable,
-transactional key/value database so it can be a good starting point for people
-interested in how databases work.
-
-The best places to start are the main entry points into Bolt:
-
-- `Open()` - Initializes the reference to the database. It's responsible for
- creating the database if it doesn't exist, obtaining an exclusive lock on the
- file, reading the meta pages, & memory-mapping the file.
-
-- `DB.Begin()` - Starts a read-only or read-write transaction depending on the
- value of the `writable` argument. This requires briefly obtaining the "meta"
- lock to keep track of open transactions. Only one read-write transaction can
- exist at a time so the "rwlock" is acquired during the life of a read-write
- transaction.
-
-- `Bucket.Put()` - Writes a key/value pair into a bucket. After validating the
- arguments, a cursor is used to traverse the B+tree to the page and position
- where they key & value will be written. Once the position is found, the bucket
- materializes the underlying page and the page's parent pages into memory as
- "nodes". These nodes are where mutations occur during read-write transactions.
- These changes get flushed to disk during commit.
-
-- `Bucket.Get()` - Retrieves a key/value pair from a bucket. This uses a cursor
- to move to the page & position of a key/value pair. During a read-only
- transaction, the key and value data is returned as a direct reference to the
- underlying mmap file so there's no allocation overhead. For read-write
- transactions, this data may reference the mmap file or one of the in-memory
- node values.
-
-- `Cursor` - This object is simply for traversing the B+tree of on-disk pages
- or in-memory nodes. It can seek to a specific key, move to the first or last
- value, or it can move forward or backward. The cursor handles the movement up
- and down the B+tree transparently to the end user.
-
-- `Tx.Commit()` - Converts the in-memory dirty nodes and the list of free pages
- into pages to be written to disk. Writing to disk then occurs in two phases.
- First, the dirty pages are written to disk and an `fsync()` occurs. Second, a
- new meta page with an incremented transaction ID is written and another
- `fsync()` occurs. This two phase write ensures that partially written data
- pages are ignored in the event of a crash since the meta page pointing to them
- is never written. Partially written meta pages are invalidated because they
- are written with a checksum.

-/*
-Package bolt implements a low-level key/value store in pure Go. It supports
-fully serializable transactions, ACID semantics, and lock-free MVCC with
-multiple readers and a single writer. Bolt can be used for projects that
-want a simple data store without the need to add large dependencies such as
-Postgres or MySQL.
-
-Bolt is a single-level, zero-copy, B+tree data store. This means that Bolt is
-optimized for fast read access and does not require recovery in the event of a
-system crash. Transactions which have not finished committing will simply be
-rolled back in the event of a crash.
-
-The design of Bolt is based on Howard Chu's LMDB database project.
-
-Bolt currently works on Windows, Mac OS X, and Linux.
-
-
-Basics
-
-There are only a few types in Bolt: DB, Bucket, Tx, and Cursor. The DB is
-a collection of buckets and is represented by a single file on disk. A bucket is
-a collection of unique keys that are associated with values.
-
-Transactions provide either read-only or read-write access to the database.
-Read-only transactions can retrieve key/value pairs and can use Cursors to
-iterate over the dataset sequentially. Read-write transactions can create and
-delete buckets and can insert and remove keys. Only one read-write transaction
-is allowed at a time.
-
-
-Caveats
-
-The database uses a read-only, memory-mapped data file to ensure that
-applications cannot corrupt the database, however, this means that keys and
-values returned from Bolt cannot be changed. Writing to a read-only byte slice
-will cause Go to panic.
-
-Keys and values retrieved from the database are only valid for the life of
-the transaction. When used outside the transaction, these byte slices can
-point to different data or can point to invalid memory which will cause a panic.
-

-
-// Package redis is a client for the Redis database.
-//
-// The Redigo FAQ (https://github.com/garyburd/redigo/wiki/FAQ) contains more
-// documentation about this package.
-//
-// Connections
-//
-// The Conn interface is the primary interface for working with Redis.
-// Applications create connections by calling the Dial, DialWithTimeout or
-// NewConn functions. In the future, functions will be added for creating
-// sharded and other types of connections.
-//
-// The application must call the connection Close method when the application
-// is done with the connection.
-//
-// Executing Commands
-//
-// The Conn interface has a generic method for executing Redis commands:
-//
-// Do(commandName string, args ...interface{}) (reply interface{}, err error)
-//
-// The Redis command reference (http://redis.io/commands) lists the available
-// commands. An example of using the Redis APPEND command is:
-//
-// n, err := conn.Do("APPEND", "key", "value")
-//
-// The Do method converts command arguments to binary strings for transmission
-// to the server as follows:
-//
-// Go Type Conversion
-// []byte Sent as is
-// string Sent as is
-// int, int64 strconv.FormatInt(v)
-// float64 strconv.FormatFloat(v, 'g', -1, 64)
-// bool true -> "1", false -> "0"
-// nil ""
-// all other types fmt.Print(v)
-//
-// Redis command reply types are represented using the following Go types:
-//
-// Redis type Go type
-// error redis.Error
-// integer int64
-// simple string string
-// bulk string []byte or nil if value not present.
-// array []interface{} or nil if value not present.
-//
-// Use type assertions or the reply helper functions to convert from
-// interface{} to the specific Go type for the command result.
-//
-// Pipelining
-//
-// Connections support pipelining using the Send, Flush and Receive methods.
-//
-// Send(commandName string, args ...interface{}) error
-// Flush() error
-// Receive() (reply interface{}, err error)
-//
-// Send writes the command to the connection's output buffer. Flush flushes the
-// connection's output buffer to the server. Receive reads a single reply from
-// the server. The following example shows a simple pipeline.
-//
-// c.Send("SET", "foo", "bar")
-// c.Send("GET", "foo")
-// c.Flush()
-// c.Receive() // reply from SET
-// v, err = c.Receive() // reply from GET
-//
-// The Do method combines the functionality of the Send, Flush and Receive
-// methods. The Do method starts by writing the command and flushing the output
-// buffer. Next, the Do method receives all pending replies including the reply
-// for the command just sent by Do. If any of the received replies is an error,
-// then Do returns the error. If there are no errors, then Do returns the last
-// reply. If the command argument to the Do method is "", then the Do method
-// will flush the output buffer and receive pending replies without sending a
-// command.
-//
-// Use the Send and Do methods to implement pipelined transactions.
-//
-// c.Send("MULTI")
-// c.Send("INCR", "foo")
-// c.Send("INCR", "bar")
-// r, err := c.Do("EXEC")
-// fmt.Println(r) // prints [1, 1]
-//
-// Concurrency
-//
-// Connections support one concurrent caller to the Receive method and one
-// concurrent caller to the Send and Flush methods. No other concurrency is
-// supported including concurrent calls to the Do method.
-//
-// For full concurrent access to Redis, use the thread-safe Pool to get, use
-// and release a connection from within a goroutine. Connections returned from
-// a Pool have the concurrency restrictions described in the previous
-// paragraph.
-//
-// Publish and Subscribe
-//
-// Use the Send, Flush and Receive methods to implement Pub/Sub subscribers.
-//
-// c.Send("SUBSCRIBE", "example")
-// c.Flush()
-// for {
-// reply, err := c.Receive()
-// if err != nil {
-// return err
-// }
-// // process pushed message
-// }
-//
-// The PubSubConn type wraps a Conn with convenience methods for implementing
-// subscribers. The Subscribe, PSubscribe, Unsubscribe and PUnsubscribe methods
-// send and flush a subscription management command. The receive method
-// converts a pushed message to convenient types for use in a type switch.
-//
-// psc := redis.PubSubConn{Conn: c}

-// Reply Helpers
-//
-// The Bool, Int, Bytes, String, Strings and Values functions convert a reply
-// to a value of a specific type. To allow convenient wrapping of calls to the
-// connection Do and Receive methods, the functions take a second argument of
-// type error. If the error is non-nil, then the helper function returns the
-// error. If the error is nil, the function converts the reply to the specified
-// type:
-//
-// exists, err := redis.Bool(c.Do("EXISTS", "foo"))
-// if err != nil {
-// // handle error return from c.Do or type conversion error.
-// }
-//
-// The Scan function converts elements of a array reply to Go types:
-//
-// var value1 int
-// var value2 string
-// reply, err := redis.Values(c.Do("MGET", "key1", "key2"))
-// if err != nil {
-// // handle error
-// }
-// if _, err := redis.Scan(reply, &value1, &value2); err != nil {
-// // handle error
-// }
-//
-// Errors
-//
-// Connection methods return error replies from the server as type redis.Error.
-//
-// Call the connection Err() method to determine if the connection encountered
-// non-recoverable error such as a network error or protocol parsing error. If
-// Err() returns a non-nil value, then the connection is not usable and should
-// be closed.

-## API Examples
-
-### Using GET, POST, PUT, PATCH, DELETE and OPTIONS
-
-```go
-func main() {
- // Disable Console Color
- // gin.DisableConsoleColor()
-
- // Creates a gin router with default middleware:
- // logger and recovery (crash-free) middleware
- router := gin.Default()
-
- router.GET("/someGet", getting)
- router.POST("/somePost", posting)
- router.PUT("/somePut", putting)
- router.DELETE("/someDelete", deleting)
- router.PATCH("/somePatch", patching)
- router.HEAD("/someHead", head)
- router.OPTIONS("/someOptions", options)
-
- // By default it serves on :8080 unless a
- // PORT environment variable was defined.
- router.Run()
- // router.Run(":3000") for a hard coded port
-}
-```
-
-### Parameters in path
-
-```go
-func main() {
- router := gin.Default()
-
- // This handler will match /user/john but will not match neither /user/ or /user
- router.GET("/user/:name", func(c *gin.Context) {
- name := c.Param("name")
- c.String(http.StatusOK, "Hello %s", name)
- })
-
- // However, this one will match /user/john/ and also /user/john/send
- // If no other routers match /user/john, it will redirect to /user/john/
- router.GET("/user/:name/*action", func(c *gin.Context) {
- name := c.Param("name")
- action := c.Param("action")
- message := name + " is " + action
- c.String(http.StatusOK, message)
- })
-
- router.Run(":8080")
-}
-```
-
-### Querystring parameters
-```go
-func main() {
- router := gin.Default()
-
- // Query string parameters are parsed using the existing underlying request object.
- // The request responds to a url matching: /welcome?firstname=Jane&lastname=Doe
- router.GET("/welcome", func(c *gin.Context) {
- firstname := c.DefaultQuery("firstname", "Guest")
- lastname := c.Query("lastname") // shortcut for c.Request.URL.Query().Get("lastname")
-
- c.String(http.StatusOK, "Hello %s %s", firstname, lastname)
- })
- router.Run(":8080")
-}
-```
-
-### Multipart/Urlencoded Form
-

-
- router.POST("/form_post", func(c *gin.Context) {
- message := c.PostForm("message")
- nick := c.DefaultPostForm("nick", "anonymous")
-
- c.JSON(200, gin.H{
- "status": "posted",
- "message": message,
- "nick": nick,
- })
- })
- router.Run(":8080")
-}
-```
-
-### Another example: query + post form
-
-```
-POST /post?id=1234&page=1 HTTP/1.1
-Content-Type: application/x-www-form-urlencoded
-
-name=manu&message=this_is_great
-```
-
-```go
-func main() {

-
- id := c.Query("id")
- page := c.DefaultQuery("page", "0")
- name := c.PostForm("name")
- message := c.PostForm("message")
-
- fmt.Printf("id: %s; page: %s; name: %s; message: %s", id, page, name, message)
- })
- router.Run(":8080")
-}
-```
-
-```
-id: 1234; page: 1; name: manu; message: this_is_great
-```
-
-### Upload files
-
-#### Single file
-
-References issue [#774](https://github.com/gin-gonic/gin/issues/774) and detail [example code](examples/upload-file/single).
-
-```go
-func main() {
- router := gin.Default()
- router.POST("/upload", func(c *gin.Context) {
- // single file
- file, _ := c.FormFile("file")
- log.Println(file.Filename)
-
- c.String(http.StatusOK, fmt.Printf("'%s' uploaded!", file.Filename))
- })
- router.Run(":8080")
-}
-```
-
-How to `curl`:
-
-```bash
-curl -X POST http://localhost:8080/upload \
- -F "file=@/Users/appleboy/test.zip" \
- -H "Content-Type: multipart/form-data"
-```
-
-#### Multiple files
-
-See the detail [example code](examples/upload-file/multiple).
-
-```go
-func main() {
- router := gin.Default()
- router.POST("/upload", func(c *gin.Context) {
- // Multipart form
- form, _ := c.MultipartForm()
- files := form.File["upload[]"]
-
- for _, file := range files {
- log.Println(file.Filename)
- }
- c.String(http.StatusOK, fmt.Printf("%d files uploaded!", len(files)))
- })
- router.Run(":8080")
-}
-```
-
-How to `curl`:
-
-```bash
-curl -X POST http://localhost:8080/upload \
- -F "upload[]=@/Users/appleboy/test1.zip" \
- -F "upload[]=@/Users/appleboy/test2.zip" \
- -H "Content-Type: multipart/form-data"
-```
-
-### Grouping routes
-
-```go
-func main() {
- router := gin.Default()
-
- // Simple group: v1
- v1 := router.Group("/v1")
- {
- v1.POST("/login", loginEndpoint)
- v1.POST("/submit", submitEndpoint)
- v1.POST("/read", readEndpoint)
- }
-
- // Simple group: v2
- v2 := router.Group("/v2")
- {
- v2.POST("/login", loginEndpoint)
- v2.POST("/submit", submitEndpoint)
- v2.POST("/read", readEndpoint)
- }
-
- router.Run(":8080")
-}
-```
-
-
-### Blank Gin without middleware by default
-
-Use
-
-```go
-r := gin.New()
-```
-instead of
-
-```go
-r := gin.Default()
-```
-
-
-### Using middleware
-```go
-func main() {
- // Creates a router without any middleware by default
- r := gin.New()
-
- // Global middleware
- r.Use(gin.Logger())
- r.Use(gin.Recovery())
-
- // Per route middleware, you can add as many as you desire.
- r.GET("/benchmark", MyBenchLogger(), benchEndpoint)
-
- // Authorization group
- // authorized := r.Group("/", AuthRequired())
- // exactly the same as:
- authorized := r.Group("/")
- // per group middleware! in this case we use the custom created
- // AuthRequired() middleware just in the "authorized" group.
- authorized.Use(AuthRequired())
- {
- authorized.POST("/login", loginEndpoint)
- authorized.POST("/submit", submitEndpoint)
- authorized.POST("/read", readEndpoint)
-
- // nested group
- testing := authorized.Group("testing")
- testing.GET("/analytics", analyticsEndpoint)
- }
-
- // Listen and serve on 0.0.0.0:8080
- r.Run(":8080")
-}
-```
-
-### Model binding and validation
-
-To bind a request body into a type, use model binding. We currently support binding of JSON, XML and standard form values (foo=bar&boo=baz).
-
-Note that you need to set the corresponding binding tag on all fields you want to bind. For example, when binding from JSON, set `json:"fieldname"`.
-
-When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use BindWith.
-
-You can also specify that specific fields are required. If a field is decorated with `binding:"required"` and has a empty value when binding, the current request will fail with an error.
-
-```go
-// Binding from JSON
-type Login struct {
- User string `form:"user" json:"user" binding:"required"`
- Password string `form:"password" json:"password" binding:"required"`
-}
-
-func main() {
- router := gin.Default()
-
- // Example for binding JSON ({"user": "manu", "password": "123"})
- router.POST("/loginJSON", func(c *gin.Context) {
- var json Login
- if c.BindJSON(&json) == nil {
- if json.User == "manu" && json.Password == "123" {
- c.JSON(http.StatusOK, gin.H{"status": "you are logged in"})
- } else {
- c.JSON(http.StatusUnauthorized, gin.H{"status": "unauthorized"})
- }
- }
- })
-
- // Example for binding a HTML form (user=manu&password=123)
- router.POST("/loginForm", func(c *gin.Context) {
- var form Login
- // This will infer what binder to use depending on the content-type header.
- if c.Bind(&form) == nil {
- if form.User == "manu" && form.Password == "123" {
- c.JSON(http.StatusOK, gin.H{"status": "you are logged in"})
- } else {
- c.JSON(http.StatusUnauthorized, gin.H{"status": "unauthorized"})
- }
- }
- })
-
- // Listen and serve on 0.0.0.0:8080
- router.Run(":8080")
-}
-```
-
-### Bind Query String
-
-See the [detail information](https://github.com/gin-gonic/gin/issues/742#issuecomment-264681292).
-
-```go
-package main
-
-import "log"
-import "github.com/gin-gonic/gin"
-
-type Person struct {
- Name string `form:"name"`
- Address string `form:"address"`
-}
-
-func main() {
- route := gin.Default()
- route.GET("/testing", startPage)
- route.Run(":8085")
-}
-
-func startPage(c *gin.Context) {
- var person Person
- // If `GET`, only `Form` binding engine (`query`) used.
- // If `POST`, first checks the `content-type` for `JSON` or `XML`, then uses `Form` (`form-data`).
- // See more at https://github.com/gin-gonic/gin/blob/develop/binding/binding.go#L45
- if c.Bind(&person) == nil {
- log.Println(person.Name)
- log.Println(person.Address)
- }
-
- c.String(200, "Success")
-}
-```
-
-
-### Multipart/Urlencoded binding
-
-```go
-package main
-
-import (
- "gopkg.in/gin-gonic/gin.v1"
-)
-
-type LoginForm struct {
- User string `form:"user" binding:"required"`
- Password string `form:"password" binding:"required"`
-}
-
-func main() {
- router := gin.Default()
- router.POST("/login", func(c *gin.Context) {
- // you can bind multipart form with explicit binding declaration:
- // c.BindWith(&form, binding.Form)
- // or you can simply use autobinding with Bind method:
- var form LoginForm
- // in this case proper binding will be automatically selected
- if c.Bind(&form) == nil {
- if form.User == "user" && form.Password == "password" {
- c.JSON(200, gin.H{"status": "you are logged in"})
- } else {
- c.JSON(401, gin.H{"status": "unauthorized"})
- }
- }
- })
- router.Run(":8080")
-}
-```
-
-Test it with:
-```sh
-$ curl -v --form user=user --form password=password http://localhost:8080/login
-```
-
-
-### XML, JSON and YAML rendering
-
-```go
-func main() {
- r := gin.Default()
-
- // gin.H is a shortcut for map[string]interface{}
- r.GET("/someJSON", func(c *gin.Context) {
- c.JSON(http.StatusOK, gin.H{"message": "hey", "status": http.StatusOK})
- })
-
- r.GET("/moreJSON", func(c *gin.Context) {
- // You also can use a struct
- var msg struct {
- Name string `json:"user"`
- Message string
- Number int
- }
- msg.Name = "Lena"
- msg.Message = "hey"
- msg.Number = 123
- // Note that msg.Name becomes "user" in the JSON
- // Will output : {"user": "Lena", "Message": "hey", "Number": 123}
- c.JSON(http.StatusOK, msg)
- })
-
- r.GET("/someXML", func(c *gin.Context) {
- c.XML(http.StatusOK, gin.H{"message": "hey", "status": http.StatusOK})
- })
-
- r.GET("/someYAML", func(c *gin.Context) {
- c.YAML(http.StatusOK, gin.H{"message": "hey", "status": http.StatusOK})
- })
-
- // Listen and serve on 0.0.0.0:8080
- r.Run(":8080")
-}
-```
-
-### Serving static files
-
-```go
-func main() {
- router := gin.Default()
- router.Static("/assets", "./assets")
- router.StaticFS("/more_static", http.Dir("my_file_system"))
- router.StaticFile("/favicon.ico", "./resources/favicon.ico")
-
- // Listen and serve on 0.0.0.0:8080
- router.Run(":8080")
-}
-```
-
-### HTML rendering
-
-Using LoadHTMLGlob() or LoadHTMLFiles()
-
-```go
-func main() {
- router := gin.Default()
- router.LoadHTMLGlob("templates/*")
- //router.LoadHTMLFiles("templates/template1.html", "templates/template2.html")
- router.GET("/index", func(c *gin.Context) {
- c.HTML(http.StatusOK, "index.tmpl", gin.H{
- "title": "Main website",
- })
- })
- router.Run(":8080")
-}
-```
-templates/index.tmpl
-```html
-
-
-
-{{ end }}
-```
-
-You can also use your own html template render
-
-```go
-import "html/template"
-
-func main() {
- router := gin.Default()
- html := template.Must(template.ParseFiles("file1", "file2"))
- router.SetHTMLTemplate(html)
- router.Run(":8080")
-}
-```
-
-### Multitemplate
-
-Gin allow by default use only one html.Template. Check [a multitemplate render](https://github.com/gin-contrib/multitemplate) for using features like go 1.6 `block template`.
-
-### Redirects
-
-Issuing a HTTP redirect is easy:
-
-```go
-r.GET("/test", func(c *gin.Context) {
- c.Redirect(http.StatusMovedPermanently, "http://www.google.com/")
-})
-```
-Both internal and external locations are supported.
-
-
-### Custom Middleware
-
-```go
-func Logger() gin.HandlerFunc {
- return func(c *gin.Context) {
- t := time.Now()
-
- // Set example variable
- c.Set("example", "12345")
-
- // before request
-
- c.Next()
-
- // after request
- latency := time.Since(t)
- log.Print(latency)
-
- // access the status we are sending
- status := c.Writer.Status()
- log.Println(status)
- }
-}
-
-func main() {
- r := gin.New()
- r.Use(Logger())
-
- r.GET("/test", func(c *gin.Context) {
- example := c.MustGet("example").(string)
-
- // it would print: "12345"
- log.Println(example)
- })
-
- // Listen and serve on 0.0.0.0:8080
- r.Run(":8080")
-}
-```
-
-### Using BasicAuth() middleware
-```go
-// simulate some private data
-var secrets = gin.H{
- "foo": gin.H{"email": "foo@bar.com", "phone": "123433"},
- "austin": gin.H{"email": "austin@example.com", "phone": "666"},
- "lena": gin.H{"email": "lena@guapa.com", "phone": "523443"},
-}
-
-func main() {
- r := gin.Default()
-
- // Group using gin.BasicAuth() middleware
- // gin.Accounts is a shortcut for map[string]string
- authorized := r.Group("/admin", gin.BasicAuth(gin.Accounts{
- "foo": "bar",
- "austin": "1234",
- "lena": "hello2",
- "manu": "4321",
- }))
-
- // /admin/secrets endpoint
- // hit "localhost:8080/admin/secrets
- authorized.GET("/secrets", func(c *gin.Context) {
- // get user, it was set by the BasicAuth middleware
- user := c.MustGet(gin.AuthUserKey).(string)
- if secret, ok := secrets[user]; ok {
- c.JSON(http.StatusOK, gin.H{"user": user, "secret": secret})
- } else {
- c.JSON(http.StatusOK, gin.H{"user": user, "secret": "NO SECRET :("})
- }
- })
-
- // Listen and serve on 0.0.0.0:8080
- r.Run(":8080")
-}
-```
-
-
-### Goroutines inside a middleware
-When starting inside a middleware or handler, you **SHOULD NOT** use the original context inside it, you have to use a read-only copy.
-
-```go
-func main() {
- r := gin.Default()
-
- r.GET("/long_async", func(c *gin.Context) {
- // create copy to be used inside the goroutine
- cCp := c.Copy()
- go func() {
- // simulate a long task with time.Sleep(). 5 seconds
- time.Sleep(5 * time.Second)
-
- // note that you are using the copied context "cCp", IMPORTANT
- log.Println("Done! in path " + cCp.Request.URL.Path)
- }()
- })
-
- r.GET("/long_sync", func(c *gin.Context) {
- // simulate a long task with time.Sleep(). 5 seconds
- time.Sleep(5 * time.Second)
-
- // since we are NOT using a goroutine, we do not have to copy the context
- log.Println("Done! in path " + c.Request.URL.Path)
- })
-
- // Listen and serve on 0.0.0.0:8080
- r.Run(":8080")
-}
-```
-
-### Custom HTTP configuration
-
-Use `http.ListenAndServe()` directly, like this:
-
-```go
-func main() {
- router := gin.Default()
- http.ListenAndServe(":8080", router)
-}
-```
-or
-
-```go
-func main() {
- router := gin.Default()
-
- s := &http.Server{
- Addr: ":8080",
- Handler: router,
- ReadTimeout: 10 * time.Second,
- WriteTimeout: 10 * time.Second,
- MaxHeaderBytes: 1 << 20,
- }
- s.ListenAndServe()
-}
-```
-
-### Graceful restart or stop
-
-Do you want to graceful restart or stop your web server?
-There are some ways this can be done.
-
-We can use [fvbock/endless](https://github.com/fvbock/endless) to replace the default `ListenAndServe`. Refer issue [#296](https://github.com/gin-gonic/gin/issues/296) for more details.
-
-```go
-router := gin.Default()
-router.GET("/", handler)
-// [...]
-endless.ListenAndServe(":4242", router)
-```
-
-An alternative to endless:
-
-* [manners](https://github.com/braintree/manners): A polite Go HTTP server that shuts down gracefully.

-Equal returns true iff protocol buffers a and b are equal.
-The arguments must both be pointers to protocol buffer structs.
-
-Equality is defined in this way:
- - Two messages are equal iff they are the same type,
- corresponding fields are equal, unknown field sets
- are equal, and extensions sets are equal.
- - Two set scalar fields are equal iff their values are equal.
- If the fields are of a floating-point type, remember that
- NaN != x for all x, including NaN. If the message is defined
- in a proto3 .proto file, fields are not "set"; specifically,
- zero length proto3 "bytes" fields are equal (nil == {}).
- - Two repeated fields are equal iff their lengths are the same,
- and their corresponding elements are equal. Note a "bytes" field,
- although represented by []byte, is not a repeated field and the
- rule for the scalar fields described above applies.
- - Two unset fields are equal.
- - Two unknown field sets are equal if their current
- encoded state is equal.
- - Two extension sets are equal iff they have corresponding
- elements that are pairwise equal.
- - Two map fields are equal iff their lengths are the same,
- and they contain the same set of elements. Zero-length map
- fields are equal.
- - Every other combination of things are not equal.

-Package proto converts data structures to and from the wire format of
-protocol buffers. It works in concert with the Go source code generated
-for .proto files by the protocol compiler.
-
-A summary of the properties of the protocol buffer interface
-for a protocol buffer variable v:
-
- - Names are turned from camel_case to CamelCase for export.
- - There are no methods on v to set fields; just treat
- them as structure fields.
- - There are getters that return a field's value if set,
- and return the field's default value if unset.
- The getters work even if the receiver is a nil message.
- - The zero value for a struct is its correct initialization state.
- All desired fields must be set before marshaling.
- - A Reset() method will restore a protobuf struct to its zero state.
- - Non-repeated fields are pointers to the values; nil means unset.
- That is, optional or required field int32 f becomes F *int32.
- - Repeated fields are slices.
- - Helper functions are available to aid the setting of fields.
- msg.Foo = proto.String("hello") // set field
- - Constants are defined to hold the default values of all fields that
- have them. They have the form Default_StructName_FieldName.
- Because the getter methods handle defaulted values,
- direct use of these constants should be rare.
- - Enums are given type names and maps from names to values.
- Enum values are prefixed by the enclosing message's name, or by the
- enum's type name if it is a top-level enum. Enum types have a String
- method, and a Enum method to assist in message construction.
- - Nested messages, groups and enums have type names prefixed with the name of
- the surrounding message type.
- - Extensions are given descriptor names that start with E_,
- followed by an underscore-delimited list of the nested messages
- that contain it (if any) followed by the CamelCased name of the
- extension field itself. HasExtension, ClearExtension, GetExtension
- and SetExtension are functions for manipulating extensions.
- - Oneof field sets are given a single field in their message,
- with distinguished wrapper types for each possible field value.
- - Marshal and Unmarshal are functions to encode and decode the wire format.
-
-When the .proto file specifies `syntax="proto3"`, there are some differences:
-
- - Non-repeated fields of non-message type are values instead of pointers.
- - Getters are only generated for message and oneof fields.
- - Enum types do not get an Enum method.
-
-The simplest way to describe this is to see an example.
-Given file test.proto, containing
-
- package example;
-
- enum FOO { X = 17; }
-
- message Test {
- required string label = 1;
- optional int32 type = 2 [default=77];
- repeated int64 reps = 3;
- optional group OptionalGroup = 4 {
- required string RequiredField = 5;
- }
- oneof union {
- int32 number = 6;
- string name = 7;

-Package context stores values shared during a request lifetime.
-
-Note: gorilla/context, having been born well before `context.Context` existed,
-does not play well > with the shallow copying of the request that
-[`http.Request.WithContext`](https://golang.org/pkg/net/http/#Request.WithContext)
-(added to net/http Go 1.7 onwards) performs. You should either use *just*
-gorilla/context, or moving forward, the new `http.Request.Context()`.
-
-For example, a router can set variables extracted from the URL and later
-application handlers can access those values, or it can be used to store
-sessions values to be saved at the end of a request. There are several
-others common uses.
-
-The idea was posted by Brad Fitzpatrick to the go-nuts mailing list:
-
- http://groups.google.com/group/golang-nuts/msg/e2d679d303aa5d53
-
-Here's the basic usage: first define the keys that you will need. The key
-type is interface{} so a key can be of any type that supports equality.
-Here we define a key using a custom int type to avoid name collisions:
-
- package foo
-
- import (
- "github.com/gorilla/context"
- )
-
- type key int
-
- const MyKey key = 0
-
-Then set a variable. Variables are bound to an http.Request object, so you
-need a request instance to set a value:
-
- context.Set(r, MyKey, "bar")
-
-The application can later access the variable using the same key you provided:
-
- func MyHandler(w http.ResponseWriter, r *http.Request) {
- // val is "bar".
- val := context.Get(r, foo.MyKey)
-
- // returns ("bar", true)
- val, ok := context.GetOk(r, foo.MyKey)
- // ...
- }
-
-And that's all about the basic usage. We discuss some other ideas below.
-
-Any type can be stored in the context. To enforce a given type, make the key
-private and wrap Get() and Set() to accept and return values of a specific
-type:
-
- type key int
-
- const mykey key = 0
-
- // GetMyKey returns a value for this package from the request values.
- func GetMyKey(r *http.Request) SomeType {
- if rv := context.Get(r, mykey); rv != nil {
- return rv.(SomeType)
- }
- return nil
- }
-
- // SetMyKey sets a value for this package in the request values.
- func SetMyKey(r *http.Request, val SomeType) {
- context.Set(r, mykey, val)
- }
-
-Variables must be cleared at the end of a request, to remove all values
-that were stored. This can be done in an http.Handler, after a request was
-served. Just call Clear() passing the request:
-
- context.Clear(r)
-
-...or use ClearHandler(), which conveniently wraps an http.Handler to clear
-variables at the end of a request lifetime.
-
-The Routers from the packages gorilla/mux and gorilla/pat call Clear()
-so if you are using either of them you don't need to clear the context manually.

-============
-[![GoDoc](https://godoc.org/github.com/gorilla/securecookie?status.svg)](https://godoc.org/github.com/gorilla/securecookie) [![Build Status](https://travis-ci.org/gorilla/securecookie.png?branch=master)](https://travis-ci.org/gorilla/securecookie)
-
-securecookie encodes and decodes authenticated and optionally encrypted
-cookie values.
-
-Secure cookies can't be forged, because their values are validated using HMAC.
-When encrypted, the content is also inaccessible to malicious eyes. It is still
-recommended that sensitive data not be stored in cookies, and that HTTPS be used
-to prevent cookie [replay attacks](https://en.wikipedia.org/wiki/Replay_attack).
-
-## Examples
-
-To use it, first create a new SecureCookie instance:
-
-```go
-// Hash keys should be at least 32 bytes long
-var hashKey = []byte("very-secret")
-// Block keys should be 16 bytes (AES-128) or 32 bytes (AES-256) long.
-// Shorter keys may weaken the encryption used.
-var blockKey = []byte("a-lot-secret")
-var s = securecookie.New(hashKey, blockKey)
-```
-
-The hashKey is required, used to authenticate the cookie value using HMAC.
-It is recommended to use a key with 32 or 64 bytes.
-
-The blockKey is optional, used to encrypt the cookie value -- set it to nil
-to not use encryption. If set, the length must correspond to the block size
-of the encryption algorithm. For AES, used by default, valid lengths are
-16, 24, or 32 bytes to select AES-128, AES-192, or AES-256.
-
-Strong keys can be created using the convenience function GenerateRandomKey().
-
-Once a SecureCookie instance is set, use it to encode a cookie value:
-
-```go
-func SetCookieHandler(w http.ResponseWriter, r *http.Request) {
- value := map[string]string{
- "foo": "bar",
- }
- if encoded, err := s.Encode("cookie-name", value); err == nil {
- cookie := &http.Cookie{
- Name: "cookie-name",
- Value: encoded,
- Path: "/",
- Secure: true,
- HttpOnly: true,
- }
- http.SetCookie(w, cookie)
- }
-}
-```
-
-Later, use the same SecureCookie instance to decode and validate a cookie
-value:
-
-```go
-func ReadCookieHandler(w http.ResponseWriter, r *http.Request) {
- if cookie, err := r.Cookie("cookie-name"); err == nil {
- value := make(map[string]string)
- if err = s2.Decode("cookie-name", cookie.Value, &value); err == nil {
- fmt.Fprintf(w, "The value of foo is %q", value["foo"])
- }
- }
-}
-```
-
-We stored a map[string]string, but secure cookies can hold any value that
-can be encoded using `encoding/gob`. To store custom types, they must be
-registered first using gob.Register(). For basic types this is not needed;
-it works out of the box. An optional JSON encoder that uses `encoding/json` is
-available for types compatible with JSON.

-Once a SecureCookie instance is set, use it to encode a cookie value:
-
- func SetCookieHandler(w http.ResponseWriter, r *http.Request) {
- value := map[string]string{
- "foo": "bar",
- }
- if encoded, err := s.Encode("cookie-name", value); err == nil {
- cookie := &http.Cookie{
- Name: "cookie-name",
- Value: encoded,
- Path: "/",
- }
- http.SetCookie(w, cookie)
- }
- }
-
-Later, use the same SecureCookie instance to decode and validate a cookie
-value:
-
- func ReadCookieHandler(w http.ResponseWriter, r *http.Request) {
- if cookie, err := r.Cookie("cookie-name"); err == nil {
- value := make(map[string]string)
- if err = s2.Decode("cookie-name", cookie.Value, &value); err == nil {
- fmt.Fprintf(w, "The value of foo is %q", value["foo"])
- }
- }
- }
-
-We stored a map[string]string, but secure cookies can hold any value that
-can be encoded using encoding/gob. To store custom types, they must be
-registered first using gob.Register(). For basic types this is not needed;
-it works out of the box.

-[![GoDoc](https://godoc.org/github.com/gorilla/sessions?status.svg)](https://godoc.org/github.com/gorilla/sessions) [![Build Status](https://travis-ci.org/gorilla/sessions.png?branch=master)](https://travis-ci.org/gorilla/sessions)
-
-gorilla/sessions provides cookie and filesystem sessions and infrastructure for
-custom session backends.
-
-The key features are:
-
-* Simple API: use it as an easy way to set signed (and optionally
- encrypted) cookies.
-* Built-in backends to store sessions in cookies or the filesystem.
-* Flash messages: session values that last until read.
-* Convenient way to switch session persistency (aka "remember me") and set
- other attributes.
-* Mechanism to rotate authentication and encryption keys.
-* Multiple sessions per request, even using different backends.
-* Interfaces and infrastructure for custom session backends: sessions from
- different stores can be retrieved and batch-saved using a common API.
-
-Let's start with an example that shows the sessions API in a nutshell:
-
-```go
- import (
- "net/http"
- "github.com/gorilla/sessions"
- )
-
- var store = sessions.NewCookieStore([]byte("something-very-secret"))
-
- func MyHandler(w http.ResponseWriter, r *http.Request) {
- // Get a session. We're ignoring the error resulted from decoding an
- // existing session: Get() always returns a session, even if empty.
- session, _ := store.Get(r, "session-name")
- // Set some session values.
- session.Values["foo"] = "bar"
- session.Values[42] = 43
- // Save it before we write to the response/return from the handler.
- session.Save(r, w)
- }
-```
-
-First we initialize a session store calling `NewCookieStore()` and passing a
-secret key used to authenticate the session. Inside the handler, we call
-`store.Get()` to retrieve an existing session or a new one. Then we set some
-session values in session.Values, which is a `map[interface{}]interface{}`.
-And finally we call `session.Save()` to save the session in the response.
-
-Important Note: If you aren't using gorilla/mux, you need to wrap your handlers
-with
-[`context.ClearHandler`](http://www.gorillatoolkit.org/pkg/context#ClearHandler)
-as or else you will leak memory! An easy way to do this is to wrap the top-level
-mux when calling http.ListenAndServe:
-
-More examples are available [on the Gorilla
-website](http://www.gorillatoolkit.org/pkg/sessions).

-Package sessions provides cookie and filesystem sessions and
-infrastructure for custom session backends.
-
-The key features are:

- encrypted) cookies.
- * Built-in backends to store sessions in cookies or the filesystem.
- * Flash messages: session values that last until read.

-
-Let's start with an example that shows the sessions API in a nutshell:
-
- import (
- "net/http"
- "github.com/gorilla/sessions"
- )
-
- var store = sessions.NewCookieStore([]byte("something-very-secret"))
-
- func MyHandler(w http.ResponseWriter, r *http.Request) {
- // Get a session. We're ignoring the error resulted from decoding an
- // existing session: Get() always returns a session, even if empty.
- session, err := store.Get(r, "session-name")
- if err != nil {
- http.Error(w, err.Error(), http.StatusInternalServerError)
- return
- }
-
- // Set some session values.
- session.Values["foo"] = "bar"
- session.Values[42] = 43
- // Save it before we write to the response/return from the handler.
- session.Save(r, w)
- }
-
-First we initialize a session store calling NewCookieStore() and passing a
-secret key used to authenticate the session. Inside the handler, we call
-store.Get() to retrieve an existing session or a new one. Then we set some
-session values in session.Values, which is a map[interface{}]interface{}.
-And finally we call session.Save() to save the session in the response.
-
-Note that in production code, we should check for errors when calling
-session.Save(r, w), and either display an error message or otherwise handle it.
-
-Save must be called before writing to the response, otherwise the session
-cookie will not be sent to the client.
-
-Important Note: If you aren't using gorilla/mux, you need to wrap your handlers
-with context.ClearHandler as or else you will leak memory! An easy way to do this
-is to wrap the top-level mux when calling http.ListenAndServe:
-
- http.ListenAndServe(":8080", context.ClearHandler(http.DefaultServeMux))
-
-The ClearHandler function is provided by the gorilla/context package.
-
-That's all you need to know for the basic usage. Let's take a look at other
-options, starting with flash messages.
-
-Flash messages are session values that last until read. The term appeared with
-Ruby On Rails a few years back. When we request a flash message, it is removed
-from the session. To add a flash, call session.AddFlash(), and to get all
-flashes, call session.Flashes(). Here is an example:
-
- func MyHandler(w http.ResponseWriter, r *http.Request) {
- // Get a session.
- session, err := store.Get(r, "session-name")
- if err != nil {
- http.Error(w, err.Error(), http.StatusInternalServerError)
- return
- }
-
- // Get the previously flashes, if any.
- if flashes := session.Flashes(); len(flashes) > 0 {
- // Use the flash values.
- } else {
- // Set a new flash.
- session.AddFlash("Hello, flash messages world!")
- }
- session.Save(r, w)
- }
-
-Flash messages are useful to set information to be read after a redirection,
-like after form submissions.
-
-There may also be cases where you want to store a complex datatype within a
-session, such as a struct. Sessions are serialised using the encoding/gob package,
-so it is easy to register new datatypes for storage in sessions:
-
- import(
- "encoding/gob"
- "github.com/gorilla/sessions"
- )
-
- type Person struct {
- FirstName string
- LastName string
- Email string
- Age int
- }
-
- type M map[string]interface{}
-
- func init() {
-
- gob.Register(&Person{})
- gob.Register(&M{})
- }
-
-As it's not possible to pass a raw type as a parameter to a function, gob.Register()
-relies on us passing it a value of the desired type. In the example above we've passed
-it a pointer to a struct and a pointer to a custom type representing a
-map[string]interface. (We could have passed non-pointer values if we wished.) This will
-then allow us to serialise/deserialise values of those types to and from our sessions.
-
-Note that because session values are stored in a map[string]interface{}, there's
-a need to type-assert data when retrieving it. We'll use the Person struct we registered above:
-
- func MyHandler(w http.ResponseWriter, r *http.Request) {
- session, err := store.Get(r, "session-name")
- if err != nil {
- http.Error(w, err.Error(), http.StatusInternalServerError)
- return
- }
-
- // Retrieve our struct and type-assert it
- val := session.Values["person"]
- var person = &Person{}
- if person, ok := val.(*Person); !ok {
- // Handle the case that it's not an expected type
- }
-
- // Now we can use our person object
- }
-
-By default, session cookies last for a month. This is probably too long for
-some cases, but it is easy to change this and other attributes during
-runtime. Sessions can be configured individually or the store can be
-configured and then all sessions saved using it will use that configuration.
-We access session.Options or store.Options to set a new configuration. The
-fields are basically a subset of http.Cookie fields. Let's change the
-maximum age of a session to one week:
-
- session.Options = &sessions.Options{
- Path: "/",
- MaxAge: 86400 * 7,
- HttpOnly: true,
- }
-
-Sometimes we may want to change authentication and/or encryption keys without
-breaking existing sessions. The CookieStore supports key rotation, and to use
-it you just need to set multiple authentication and encryption keys, in pairs,
-to be tested in order:
-
- var store = sessions.NewCookieStore(
- []byte("new-authentication-key"),
- []byte("new-encryption-key"),
- []byte("old-authentication-key"),
- []byte("old-encryption-key"),
- )
-
-New sessions will be saved using the first pair. Old sessions can still be
-read because the first pair will fail, and the second will be tested. This
-makes it easy to "rotate" secret keys and still be able to validate existing
-sessions. Note: for all pairs the encryption key is optional; set it to nil
-or omit it and and encryption won't be used.
-
-Multiple sessions can be used in the same request, even with different
-session backends. When this happens, calling Save() on each session
-individually would be cumbersome, so we have a way to save all sessions
-at once: it's sessions.Save(). Here's an example:
-
- var store = sessions.NewCookieStore([]byte("something-very-secret"))
-
- func MyHandler(w http.ResponseWriter, r *http.Request) {
- // Get a session and set a value.
- session1, _ := store.Get(r, "session-one")
- session1.Values["foo"] = "bar"
- // Get another session and set another value.
- session2, _ := store.Get(r, "session-two")
- session2.Values[42] = 43
- // Save all sessions.
- sessions.Save(r, w)
- }
-
-This is possible because when we call Get() from a session store, it adds the
-session to a common registry. Save() uses it to save all registered sessions.

-# Gorilla WebSocket
-
-Gorilla WebSocket is a [Go](http://golang.org/) implementation of the
-[WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol.
-
-[![Build Status](https://travis-ci.org/gorilla/websocket.svg?branch=master)](https://travis-ci.org/gorilla/websocket)
-[![GoDoc](https://godoc.org/github.com/gorilla/websocket?status.svg)](https://godoc.org/github.com/gorilla/websocket)
-
-### Documentation
-
-* [API Reference](http://godoc.org/github.com/gorilla/websocket)
-* [Chat example](https://github.com/gorilla/websocket/tree/master/examples/chat)
-* [Command example](https://github.com/gorilla/websocket/tree/master/examples/command)
-* [Client and server example](https://github.com/gorilla/websocket/tree/master/examples/echo)
-* [File watch example](https://github.com/gorilla/websocket/tree/master/examples/filewatch)
-
-### Status
-
-The Gorilla WebSocket package provides a complete and tested implementation of
-the [WebSocket](http://www.rfc-editor.org/rfc/rfc6455.txt) protocol. The
-package API is stable.
-
-### Installation
-
- go get github.com/gorilla/websocket
-
-### Protocol Compliance
-
-The Gorilla WebSocket package passes the server tests in the [Autobahn Test
-Suite](http://autobahn.ws/testsuite) using the application in the [examples/autobahn
-subdirectory](https://github.com/gorilla/websocket/tree/master/examples/autobahn).
-
-### Gorilla WebSocket compared with other packages
-
-
-
-Notes:
-
-1. Large messages are fragmented in [Chrome's new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html).
-2. The application can get the type of a received data message by implementing
- a [Codec marshal](http://godoc.org/golang.org/x/net/websocket#Codec.Marshal)
- function.
-3. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries.
- Read returns when the input buffer is full or a frame boundary is
- encountered. Each call to Write sends a single frame message. The Gorilla
- io.Reader and io.WriteCloser operate on a single WebSocket message.

-// Package websocket implements the WebSocket protocol defined in RFC 6455.
-//
-// Overview
-//
-// The Conn type represents a WebSocket connection. A server application uses
-// the Upgrade function from an Upgrader object with a HTTP request handler
-// to get a pointer to a Conn:
-//
-// var upgrader = websocket.Upgrader{
-// ReadBufferSize: 1024,
-// WriteBufferSize: 1024,
-// }
-//
-// func handler(w http.ResponseWriter, r *http.Request) {
-// conn, err := upgrader.Upgrade(w, r, nil)
-// if err != nil {
-// log.Println(err)
-// return
-// }
-// ... Use conn to send and receive messages.
-// }
-//
-// Call the connection's WriteMessage and ReadMessage methods to send and
-// receive messages as a slice of bytes. This snippet of code shows how to echo
-// messages using these methods:
-//
-// for {
-// messageType, p, err := conn.ReadMessage()
-// if err != nil {
-// return
-// }
-// if err = conn.WriteMessage(messageType, p); err != nil {
-// return err
-// }
-// }
-//
-// In above snippet of code, p is a []byte and messageType is an int with value
-// websocket.BinaryMessage or websocket.TextMessage.
-//
-// An application can also send and receive messages using the io.WriteCloser
-// and io.Reader interfaces. To send a message, call the connection NextWriter
-// method to get an io.WriteCloser, write the message to the writer and close
-// the writer when done. To receive a message, call the connection NextReader
-// method to get an io.Reader and read until io.EOF is returned. This snippet
-// shows how to echo messages using the NextWriter and NextReader methods:
-//
-// for {
-// messageType, r, err := conn.NextReader()
-// if err != nil {
-// return
-// }
-// w, err := conn.NextWriter(messageType)
-// if err != nil {
-// return err
-// }
-// if _, err := io.Copy(w, r); err != nil {
-// return err
-// }
-// if err := w.Close(); err != nil {
-// return err
-// }
-// }
-//
-// Data Messages
-//
-// The WebSocket protocol distinguishes between text and binary data messages.
-// Text messages are interpreted as UTF-8 encoded text. The interpretation of
-// binary messages is left to the application.
-//
-// This package uses the TextMessage and BinaryMessage integer constants to
-// identify the two data message types. The ReadMessage and NextReader methods
-// return the type of the received message. The messageType argument to the
-// WriteMessage and NextWriter methods specifies the type of a sent message.
-//
-// It is the application's responsibility to ensure that text messages are
-// valid UTF-8 encoded text.
-//
-// Control Messages
-//
-// The WebSocket protocol defines three types of control messages: close, ping
-// and pong. Call the connection WriteControl, WriteMessage or NextWriter
-// methods to send a control message to the peer.
-//
-// Connections handle received close messages by sending a close message to the
-// peer and returning a *CloseError from the the NextReader, ReadMessage or the
-// message Read method.
-//
-// Connections handle received ping and pong messages by invoking callback
-// functions set with SetPingHandler and SetPongHandler methods. The callback
-// functions are called from the NextReader, ReadMessage and the message Read
-// methods.
-//
-// The default ping handler sends a pong to the peer. The application's reading
-// goroutine can block for a short time while the handler writes the pong data
-// to the connection.
-//
-// The application must read the connection to process ping, pong and close
-// messages sent from the peer. If the application is not otherwise interested
-// in messages from the peer, then the application should start a goroutine to
-// read and discard messages from the peer. A simple example is:
-//
-// func readLoop(c *websocket.Conn) {
-// for {
-// if _, _, err := c.NextReader(); err != nil {
-// c.Close()
-// break
-// }
-// }
-// }
-//
-// Concurrency
-//
-// Connections support one concurrent reader and one concurrent writer.
-//
-// Applications are responsible for ensuring that no more than one goroutine
-// calls the write methods (NextWriter, SetWriteDeadline, WriteMessage,
-// WriteJSON) concurrently and that no more than one goroutine calls the read
-// methods (NextReader, SetReadDeadline, ReadMessage, ReadJSON, SetPongHandler,
-// SetPingHandler) concurrently.
-//
-// The Close and WriteControl methods can be called concurrently with all other
-// methods.
-//
-// Origin Considerations
-//
-// Web browsers allow Javascript applications to open a WebSocket connection to
-// any host. It's up to the server to enforce an origin policy using the Origin
-// request header sent by the browser.
-//
-// The Upgrader calls the function specified in the CheckOrigin field to check
-// the origin. If the CheckOrigin function returns false, then the Upgrade
-// method fails the WebSocket handshake with HTTP status 403.
-//
-// If the CheckOrigin field is nil, then the Upgrader uses a safe default: fail
-// the handshake if the Origin request header is present and not equal to the
-// Host request header.
-//
-// An application can allow connections from any origin by specifying a
-// function that always returns true:
-//
-// var upgrader = websocket.Upgrader{
-// CheckOrigin: func(r *http.Request) bool { return true },
-// }
-//
-// The deprecated Upgrade function does not enforce an origin policy. It's the
-// application's responsibility to check the Origin header before calling
-// Upgrade.
-//
-// Compression
-//
-// Per message compression extensions (RFC 7692) are experimentally supported
-// by this package in a limited capacity. Setting the EnableCompression option
-// to true in Dialer or Upgrader will attempt to negotiate per message deflate
-// support. If compression was successfully negotiated with the connection's
-// peer, any message received in compressed form will be automatically
-// decompressed. All Read methods will return uncompressed bytes.
-//
-// Per message compression of messages written to a connection can be enabled
-// or disabled by calling the corresponding Conn method:
-//
-// conn.EnableWriteCompression(true)
-//
-// Currently this package does not support compression with "context takeover".
-// This means that messages must be compressed and decompressed in isolation,
-// without retaining sliding window or dictionary state across messages. For
-// more details refer to RFC 7692.
-//
-// Use of compression is experimental and may result in decreased performance.

-lumber
-======
-
-A simple logger for Go.
-
-Provides console and file loggers that support 6 log levels. The file logger supports log backup and
-rotation.
-
-### Usage: ###
-Log to the default (console) logger
-
-```go
-lumber.Error("An error message")
-```
-
-Create a new console logger that only logs messages of level WARN or higher
-
-```go
-log := lumber.NewConsoleLogger(lumber.WARN)
-```
-
-Change the log level for a logger
-
-```go
-log.Level(lumber.INFO)
-```
-
-Create a new file logger that rotates at 5000 lines (up to 9 backups) with a 100 message buffer
-
-```go
-log := lumber.NewFileLogger("filename.log", lumber.INFO, lumber.ROTATE, 5000, 9, 100)
-// or
-log := lumber.NewRotateLogger("filename.log", 5000, 9)
-```
-
-Send messages to the log
-
-```go
-// the log methods use fmt.Printf() syntax
-log.Trace("the %s log level", "lowest")
-log.Debug("")
-log.Info("the default log level")
-log.Warn("")
-log.Error("")
-log.Fatal("the %s log level", "highest")
-```
-
-Add a prefix to label different logs
-
-```go
-log.Prefix("MYAPP")
-```
-
-Use a MultiLogger
-
-```go
-mlog := NewMultiLogger()
-mlog.AddLoggers(log1, log2)
-mlog.Warn("This message goes to multiple loggers")
-mlog.Close() // closes all loggers
-```
-
-### Modes: ###
-
-APPEND: Append if the file exists, otherwise create a new file
-
-TRUNC: Open and truncate the file, regardless of whether it already exists
-
-BACKUP: Rotate the log every time a new logger is created
-
-ROTATE: Append if the file exists, when the log reaches maxLines rotate files

-# Contributing to bluemonday
-
-Third-party patches are essential for keeping bluemonday secure and offering the features developers want. However there are a few guidelines that we need contributors to follow so that we can maintain the quality of work that developers who use bluemonday expect.
-
-## Getting Started
-
-* Make sure you have a [Github account](https://github.com/signup/free)
-
-## Submitting an Issue
-
-* Submit a ticket for your issue, assuming one does not already exist
-* Clearly describe the issue including the steps to reproduce (with sample input and output) if it is a bug
-
-If you are reporting a security flaw, you may expect that we will provide the code to fix it for you. Otherwise you may want to submit a pull request to ensure the resolution is applied sooner rather than later:
-
-* Fork the repository on Github
-* Issue a pull request containing code to resolve the issue
-
-## Submitting a Pull Request
-
-* Submit a ticket for your issue, assuming one does not already exist
-* Describe the reason for the pull request and if applicable show some example inputs and outputs to demonstrate what the patch does
-* Fork the repository on Github
-* Before submitting the pull request you should
- 1. Include tests for your patch, 1 test should encapsulate the entire patch and should refer to the Github issue
- 1. If you have added new exposed/public functionality, you should ensure it is documented appropriately
- 1. If you have added new exposed/public functionality, you should consider demonstrating how to use it within one of the helpers or shipped policies if appropriate or within a test if modifying a helper or policy is not appropriate
- 1. Run all of the tests `go test -v ./...` or `make test` and ensure all tests pass
- 1. Run gofmt `gofmt -w ./$*` or `make fmt`
- 1. Run vet `go tool vet *.go` or `make vet` and resolve any issues
- 1. Install golint using `go get -u github.com/golang/lint/golint` and run vet `golint *.go` or `make lint` and resolve every warning
-* When submitting the pull request you should
- 1. Note the issue(s) it resolves, i.e. `Closes #6` in the pull request comment to close issue #6 when the pull request is accepted
-
-Once you have submitted a pull request, we *may* merge it without changes. If we have any comments or feedback, or need you to make changes to your pull request we will update the Github pull request or the associated issue. We expect responses from you within two weeks, and we may close the pull request is there is no activity.
-
-### Contributor Licence Agreement
-
-We haven't gone for the formal "Sign a Contributor Licence Agreement" thing that projects like [puppet](https://cla.puppetlabs.com/), [Mojito](https://developer.yahoo.com/cocktails/mojito/cla/) and companies like [Google](http://code.google.com/legal/individual-cla-v1.0.html) are using.
-
-But we do need to know that we can accept and merge your contributions, so for now the act of contributing a pull request should be considered equivalent to agreeing to a contributor licence agreement, specifically:
-
-You accept that the act of submitting code to the bluemonday project is to grant a copyright licence to the project that is perpetual, worldwide, non-exclusive, no-charge, royalty free and irrevocable.
-
-You accept that all who comply with the licence of the project (BSD 3-clause) are permitted to use your contributions to the project.
-
-You accept, and by submitting code do declare, that you have the legal right to grant such a licence to the project and that each of the contributions is your own original creation.

-# bluemonday [![Build Status](https://travis-ci.org/microcosm-cc/bluemonday.svg?branch=master)](https://travis-ci.org/microcosm-cc/bluemonday) [![GoDoc](https://godoc.org/github.com/microcosm-cc/bluemonday?status.png)](https://godoc.org/github.com/microcosm-cc/bluemonday)
-
-bluemonday is a HTML sanitizer implemented in Go. It is fast and highly configurable.
-
-bluemonday takes untrusted user generated content as an input, and will return HTML that has been sanitised against a whitelist of approved HTML elements and attributes so that you can safely include the content in your web page.
-
-If you accept user generated content, and your server uses Go, you **need** bluemonday.
-
-The default policy for user generated content (`bluemonday.UGCPolicy().Sanitize()`) turns this:
-```html
-Hello World
-```
-
-Into a harmless:
-```html
-Hello World
-```
-
-And it turns this:
-```html
-XSS
-```
-
-Into this:
-```html
-XSS
-```
-
-Whilst still allowing this:
-```html
-
-
-
-```
-
-To pass through mostly unaltered (it gained a rel="nofollow" which is a good thing for user generated content):
-```html
-
-
-
-```
-
-It protects sites from [XSS](http://en.wikipedia.org/wiki/Cross-site_scripting) attacks. There are many [vectors for an XSS attack](https://www.owasp.org/index.php/XSS_Filter_Evasion_Cheat_Sheet) and the best way to mitigate the risk is to sanitize user input against a known safe list of HTML elements and attributes.
-
-You should **always** run bluemonday **after** any other processing.
-
-If you use [blackfriday](https://github.com/russross/blackfriday) or [Pandoc](http://johnmacfarlane.net/pandoc/) then bluemonday should be run after these steps. This ensures that no insecure HTML is introduced later in your process.
-
-bluemonday is heavily inspired by both the [OWASP Java HTML Sanitizer](https://code.google.com/p/owasp-java-html-sanitizer/) and the [HTML Purifier](http://htmlpurifier.org/).
-
-## Technical Summary
-
-Whitelist based, you need to either build a policy describing the HTML elements and attributes to permit (and the `regexp` patterns of attributes), or use one of the supplied policies representing good defaults.
-
-The policy containing the whitelist is applied using a fast non-validating, forward only, token-based parser implemented in the [Go net/html library](https://godoc.org/golang.org/x/net/html) by the core Go team.
-
-We expect to be supplied with well-formatted HTML (closing elements for every applicable open element, nested correctly) and so we do not focus on repairing badly nested or incomplete HTML. We focus on simply ensuring that whatever elements do exist are described in the policy whitelist and that attributes and links are safe for use on your web page. [GIGO](http://en.wikipedia.org/wiki/Garbage_in,_garbage_out) does apply and if you feed it bad HTML bluemonday is not tasked with figuring out how to make it good again.
-
-### Supported Go Versions
-
-bluemonday is regularly tested against Go 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7 and tip.
-
-We do not support Go 1.0 as we depend on `golang.org/x/net/html` which includes a reference to `io.ErrNoProgress` which did not exist in Go 1.0.
-
-## Is it production ready?
-
-*Yes*
-
-We are using bluemonday in production having migrated from the widely used and heavily field tested OWASP Java HTML Sanitizer.
-
-We are passing our extensive test suite (including AntiSamy tests as well as tests for any issues raised). Check for any [unresolved issues](https://github.com/microcosm-cc/bluemonday/issues?page=1&state=open) to see whether anything may be a blocker for you.
-
-We invite pull requests and issues to help us ensure we are offering comprehensive protection against various attacks via user generated content.
-
-## Usage
-
-Install in your `${GOPATH}` using `go get -u github.com/microcosm-cc/bluemonday`
-
-Then call it:
-```go
-package main
-
-import (
- "fmt"
-
- "github.com/microcosm-cc/bluemonday"
-)
-
-func main() {
- p := bluemonday.UGCPolicy()
- html := p.Sanitize(
- `Google`,
- )
-
- // Output:
- // Google
- fmt.Println(html)
-}
-```
-
-We offer three ways to call Sanitize:
-```go
-p.Sanitize(string) string
-p.SanitizeBytes([]byte) []byte
-p.SanitizeReader(io.Reader) bytes.Buffer
-```
-
-If you are obsessed about performance, `p.SanitizeReader(r).Bytes()` will return a `[]byte` without performing any unnecessary casting of the inputs or outputs. Though the difference is so negligible you should never need to care.
-
-You can build your own policies:
-```go
-package main
-
-import (
- "fmt"
-
- "github.com/microcosm-cc/bluemonday"
-)
-
-func main() {
- p := bluemonday.NewPolicy()
-
- // Require URLs to be parseable by net/url.Parse and either:
- // mailto: http:// or https://
- p.AllowStandardURLs()
-
- // We only allow
and
- p.AllowAttrs("href").OnElements("a")
- p.AllowElements("p")
-
- html := p.Sanitize(
- `Google`,
- )
-
- // Output:
- // Google
- fmt.Println(html)
-}
-```
-
-We ship two default policies:
-
-1. `bluemonday.StrictPolicy()` which can be thought of as equivalent to stripping all HTML elements and their attributes as it has nothing on it's whitelist. An example usage scenario would be blog post titles where HTML tags are not expected at all and if they are then the elements *and* the content of the elements should be stripped. This is a *very* strict policy.
-2. `bluemonday.UGCPolicy()` which allows a broad selection of HTML elements and attributes that are safe for user generated content. Note that this policy does *not* whitelist iframes, object, embed, styles, script, etc. An example usage scenario would be blog post bodies where a variety of formatting is expected along with the potential for TABLEs and IMGs.
-
-## Policy Building
-
-The essence of building a policy is to determine which HTML elements and attributes are considered safe for your scenario. OWASP provide an [XSS prevention cheat sheet](https://www.owasp.org/index.php/XSS_(Cross_Site_Scripting)_Prevention_Cheat_Sheet) to help explain the risks, but essentially:
-
-1. Avoid anything other than the standard HTML elements
-1. Avoid `script`, `style`, `iframe`, `object`, `embed`, `base` elements that allow code to be executed by the client or third party content to be included that can execute code
-1. Avoid anything other than plain HTML attributes with values matched to a regexp
-
-Basically, you should be able to describe what HTML is fine for your scenario. If you do not have confidence that you can describe your policy please consider using one of the shipped policies such as `bluemonday.UGCPolicy()`.
-
-To create a new policy:
-```go
-p := bluemonday.NewPolicy()
-```
-
-To add elements to a policy either add just the elements:
-```go
-p.AllowElements("b", "strong")
-```
-
-Or add elements as a virtue of adding an attribute:
-```go
-// Not the recommended pattern, see the recommendation on using .Matching() below
-p.AllowAttrs("nowrap").OnElements("td", "th")
-```
-
-Attributes can either be added to all elements:
-```go
-p.AllowAttrs("dir").Matching(regexp.MustCompile("(?i)rtl|ltr")).Globally()
-```
-
-Or attributes can be added to specific elements:
-```go
-// Not the recommended pattern, see the recommendation on using .Matching() below
-p.AllowAttrs("value").OnElements("li")
-```
-
-It is **always** recommended that an attribute be made to match a pattern. XSS in HTML attributes is very easy otherwise:
-```go
-// \p{L} matches unicode letters, \p{N} matches unicode numbers
-p.AllowAttrs("title").Matching(regexp.MustCompile(`[\p{L}\p{N}\s\-_',:\[\]!\./\\\(\)&]*`)).Globally()
-```
-
-You can stop at any time and call .Sanitize():
-```go
-// string htmlIn passed in from a HTTP POST
-htmlOut := p.Sanitize(htmlIn)
-```
-
-And you can take any existing policy and extend it:
-```go
-p := bluemonday.UGCPolicy()
-p.AllowElements("fieldset", "select", "option")
-```
-
-### Links
-
-Links are difficult beasts to sanitise safely and also one of the biggest attack vectors for malicious content.
-
-It is possible to do this:
-```go
-p.AllowAttrs("href").Matching(regexp.MustCompile(`(?i)mailto|https?`)).OnElements("a")
-```
-
-But that will not protect you as the regular expression is insufficient in this case to have prevented a malformed value doing something unexpected.
-
-We provide some additional global options for safely working with links.
-
-`RequireParseableURLs` will ensure that URLs are parseable by Go's `net/url` package:
-```go
-p.RequireParseableURLs(true)
-```
-
-If you have enabled parseable URLs then the following option will `AllowRelativeURLs`. By default this is disabled (bluemonday is a whitelist tool... you need to explicitly tell us to permit things) and when disabled it will prevent all local and scheme relative URLs (i.e. `href="localpage.html"`, `href="../home.html"` and even `href="//www.google.com"` are relative):
-```go
-p.AllowRelativeURLs(true)
-```
-
-If you have enabled parseable URLs then you can whitelist the schemes (commonly called protocol when thinking of `http` and `https`) that are permitted. Bear in mind that allowing relative URLs in the above option will allow for a blank scheme:
-```go
-p.AllowURLSchemes("mailto", "http", "https")
-```
-
-Regardless of whether you have enabled parseable URLs, you can force all URLs to have a rel="nofollow" attribute. This will be added if it does not exist, but only when the `href` is valid:
-```go
-// This applies to "a" "area" "link" elements that have a "href" attribute
-p.RequireNoFollowOnLinks(true)
-```
-
-We provide a convenience method that applies all of the above, but you will still need to whitelist the linkable elements for the URL rules to be applied to:
-```go
-p.AllowStandardURLs()
-p.AllowAttrs("cite").OnElements("blockquote", "q")
-p.AllowAttrs("href").OnElements("a", "area")
-p.AllowAttrs("src").OnElements("img")
-```
-
-An additional complexity regarding links is the data URI as defined in [RFC2397](http://tools.ietf.org/html/rfc2397). The data URI allows for images to be served inline using this format:
-
-```html
-
-```
-
-We have provided a helper to verify the mimetype followed by base64 content of data URIs links:
-
-```go
-p.AllowDataURIImages()
-```
-
-That helper will enable GIF, JPEG, PNG and WEBP images.
-
-It should be noted that there is a potential [security](http://palizine.plynt.com/issues/2010Oct/bypass-xss-filters/) [risk](https://capec.mitre.org/data/definitions/244.html) with the use of data URI links. You should only enable data URI links if you already trust the content.
-
-We also have some features to help deal with user generated content:
-```go
-p.AddTargetBlankToFullyQualifiedLinks(true)
-```
-
-This will ensure that anchor `` links that are fully qualified (the href destination includes a host name) will get `target="_blank"` added to them.
-
-Additionally any link that has `target="_blank"` after the policy has been applied will also have the `rel` attribute adjusted to add `noopener`. This means a link may start like `` and will end up as ``. It is important to note that the addition of `noopener` is a security feature and not an issue. There is an unfortunate feature to browsers that a browser window opened as a result of `target="_blank"` can still control the opener (your web page) and this protects against that. The background to this can be found here: [https://dev.to/ben/the-targetblank-vulnerability-by-example](https://dev.to/ben/the-targetblank-vulnerability-by-example)
-
-### Policy Building Helpers
-
-We also bundle some helpers to simplify policy building:
-```go
-
-// Permits the "dir", "id", "lang", "title" attributes globally
-p.AllowStandardAttributes()
-
-// Permits the "img" element and it's standard attributes
-p.AllowImages()
-
-// Permits ordered and unordered lists, and also definition lists
-p.AllowLists()
-
-// Permits HTML tables and all applicable elements and non-styling attributes
-p.AllowTables()
-```
-
-### Invalid Instructions
-
-The following are invalid:
-```go
-// This does not say where the attributes are allowed, you need to add
-// .Globally() or .OnElements(...)
-// This will be ignored without error.
-p.AllowAttrs("value")
-
-// This does not say where the attributes are allowed, you need to add
-// .Globally() or .OnElements(...)
-// This will be ignored without error.
-p.AllowAttrs(
- "type",
-).Matching(
- regexp.MustCompile("(?i)^(circle|disc|square|a|A|i|I|1)$"),
-)
-```
-
-Both examples exhibit the same issue, they declare attributes but do not then specify whether they are whitelisted globally or only on specific elements (and which elements). Attributes belong to one or more elements, and the policy needs to declare this.
-
-## Limitations
-
-We are not yet including any tools to help whitelist and sanitize CSS. Which means that unless you wish to do the heavy lifting in a single regular expression (inadvisable), **you should not allow the "style" attribute anywhere**.
-
-It is not the job of bluemonday to fix your bad HTML, it is merely the job of bluemonday to prevent malicious HTML getting through. If you have mismatched HTML elements, or non-conforming nesting of elements, those will remain. But if you have well-structured HTML bluemonday will not break it.
-
-## TODO
-
-* Add support for CSS sanitisation to allow some CSS properties based on a whitelist, possibly using the [Gorilla CSS3 scanner](http://www.gorillatoolkit.org/pkg/css/scanner)
-* Investigate whether devs want to blacklist elements and attributes. This would allow devs to take an existing policy (such as the `bluemonday.UGCPolicy()` ) that encapsulates 90% of what they're looking for but does more than they need, and to remove the extra things they do not want to make it 100% what they want
-* Investigate whether devs want a validating HTML mode, in which the HTML elements are not just transformed into a balanced tree (every start tag has a closing tag at the correct depth) but also that elements and character data appear only in their allowed context (i.e. that a `table` element isn't a descendent of a `caption`, that `colgroup`, `thead`, `tbody`, `tfoot` and `tr` are permitted, and that character data is not permitted)
-
-## Development
-
-If you have cloned this repo you will probably need the dependency:
-
-`go get golang.org/x/net/html`
-
-Gophers can use their familiar tools:
-
-`go build`
-
-`go test`
-
-I personally use a Makefile as it spares typing the same args over and over whilst providing consistency for those of us who jump from language to language and enjoy just typing `make` in a project directory and watch magic happen.
-
-`make` will build, vet, test and install the library.
-
-`make clean` will remove the library from a *single* `${GOPATH}/pkg` directory tree
-
-`make test` will run the tests
-
-`make cover` will run the tests and *open a browser window* with the coverage report
-
-`make lint` will run golint (install via `go get github.com/golang/lint/golint`)
-
-## Long term goals
-
-1. Open the code to adversarial peer review similar to the [Attack Review Ground Rules](https://code.google.com/p/owasp-java-html-sanitizer/wiki/AttackReviewGroundRules)
-1. Raise funds and pay for an external security review

-/*
-Package bluemonday provides a way of describing a whitelist of HTML elements
-and attributes as a policy, and for that policy to be applied to untrusted
-strings from users that may contain markup. All elements and attributes not on
-the whitelist will be stripped.
-
-The default bluemonday.UGCPolicy().Sanitize() turns this:
-
- Hello World
-
-Into the more harmless:
-
- Hello World
-
-And it turns this:
-
- XSS
-
-Into this:
-
- XSS
-
-Whilst still allowing this:
-
-
-
-
-
-To pass through mostly unaltered (it gained a rel="nofollow"):
-
-
-
-
-
-The primary purpose of bluemonday is to take potentially unsafe user generated
-content (from things like Markdown, HTML WYSIWYG tools, etc) and make it safe
-for you to put on your website.
-
-It protects sites against XSS (http://en.wikipedia.org/wiki/Cross-site_scripting)
-and other malicious content that a user interface may deliver. There are many
-vectors for an XSS attack (https://www.owasp.org/index.php/XSS_Filter_Evasion_Cheat_Sheet)
-and the safest thing to do is to sanitize user input against a known safe list
-of HTML elements and attributes.
-
-Note: You should always run bluemonday after any other processing.
-
-If you use blackfriday (https://github.com/russross/blackfriday) or
-Pandoc (http://johnmacfarlane.net/pandoc/) then bluemonday should be run after
-these steps. This ensures that no insecure HTML is introduced later in your
-process.
-
-bluemonday is heavily inspired by both the OWASP Java HTML Sanitizer
-(https://code.google.com/p/owasp-java-html-sanitizer/) and the HTML Purifier
-(http://htmlpurifier.org/).
-
-We ship two default policies, one is bluemonday.StrictPolicy() and can be
-thought of as equivalent to stripping all HTML elements and their attributes as
-it has nothing on it's whitelist.
-
-The other is bluemonday.UGCPolicy() and allows a broad selection of HTML
-elements and attributes that are safe for user generated content. Note that
-this policy does not whitelist iframes, object, embed, styles, script, etc.
-
-The essence of building a policy is to determine which HTML elements and
-attributes are considered safe for your scenario. OWASP provide an XSS
-prevention cheat sheet ( https://www.google.com/search?q=xss+prevention+cheat+sheet )
-to help explain the risks, but essentially:
-
- 1. Avoid whitelisting anything other than plain HTML elements
- 2. Avoid whitelisting `script`, `style`, `iframe`, `object`, `embed`, `base`
- elements
- 3. Avoid whitelisting anything other than plain HTML elements with simple
- values that you can match to a regexp
