The Cascadia package implements CSS selectors for use with the parse trees produced by the html package.
To test CSS selectors without writing Go code, check out [cascadia](https://github.com/suntong/cascadia) the command line tool, a thin wrapper around this package.

Contributing
-------------------------
We really appreciate contributions, but they must meet the following requirements:
* A PR should have a brief description of the problem/feature being proposed
* Pull requests should target the `development` branch
* Existing tests should pass and any new code should be covered with it's own test(s) (use [travis-ci](https://travis-ci.org))
* New functions should be [documented](https://blog.golang.org/godoc-documenting-go-code) clearly
* Code should pass `golint`, `go vet` and `go fmt`
We merge PRs into `development`, which is then tested in a sharded, replicated environment in our datacenter for regressions. Once everyone is happy, we merge to master - this is to maintain a bit of quality control past the usual PR process.
**Thanks** for helping!

[![Build Status](https://travis-ci.org/globalsign/mgo.svg?branch=master)](https://travis-ci.org/globalsign/mgo) [![GoDoc](https://godoc.org/github.com/globalsign/mgo?status.svg)](https://godoc.org/github.com/globalsign/mgo)
The MongoDB driver for Go
-------------------------
This fork has had a few improvements by ourselves as well as several PR's merged from the original mgo repo that are currently awaiting review.
Changes are mostly geared towards performance improvements and bug fixes, though a few new features have been added.
Further PR's (with tests) are welcome, but please maintain backwards compatibility.
Detailed documentation of the API is available at
[GoDoc](https://godoc.org/github.com/globalsign/mgo).
A [sub-package](https://godoc.org/github.com/globalsign/mgo/bson) that implements the [BSON](http://bsonspec.org) specification is also included, and may be used independently of the driver.
## Supported Versions
`mgo` is known to work well on (and has integration tests against) MongoDB v3.0, 3.2, 3.4 and 3.6.
MongoDB 4.0 is currently experimental - we would happily accept PRs to help improve support!

An Implementation of BSON for Go
--------------------------------
Package bson is an implementation of the [BSON specification](http://bsonspec.org) for Go.
While the BSON package implements the BSON spec as faithfully as possible, there
is some MongoDB specific behaviour (such as map keys `$in`, `$all`, etc) in the
`bson` package. The priority is for backwards compatibility for the `mgo`
driver, though fixes for obviously buggy behaviour is welcome (and features, etc
behind feature flags).

// Setter interface: a value implementing the bson.Setter interface will receive the BSON

//
// If setting the value works, the method should return nil or alternatively
// bson.ErrSetZero to set the respective field to its zero value (nil for
// pointer types). If SetBSON returns a value of type bson.TypeError, the
// BSON value will be omitted from a map or slice being decoded and the
// unmarshalling will continue. If it returns any other non-nil error, the
// unmarshalling procedure will stop and error out with the provided value.
//
// This interface is generally useful in pointer receivers, since the method
// will want to change the receiver. A type field that implements the Setter
// interface doesn't have to be a pointer, though.
//
// Unlike the usual behavior, unmarshalling onto a value that implements a
// Setter interface will NOT reset the value to its zero state. This allows
// the value to decide by itself how to be unmarshalled.

// }

// Package mgo (pronounced as "mango") offers a rich MongoDB driver for Go.
//
// Detailed documentation of the API is available at GoDoc:
//
// https://godoc.org/github.com/globalsign/mgo
//
// Usage of the driver revolves around the concept of sessions. To
// get started, obtain a session using the Dial function:
//
// session, err := mgo.Dial(url)
//
// This will establish one or more connections with the cluster of
// servers defined by the url parameter. From then on, the cluster
// may be queried with multiple consistency rules (see SetMode) and
// documents retrieved with statements such as:
//
// c := session.DB(database).C(collection)
// err := c.Find(query).One(&result)
//
// New sessions are typically created by calling session.Copy on the
// initial session obtained at dial time. These new sessions will share
// the same cluster information and connection pool, and may be easily
// handed into other methods and functions for organizing logic.
// Every session created must have its Close method called at the end
// of its life time, so its resources may be put back in the pool or
// collected, depending on the case.
//
// There is a sub-package that provides support for BSON, which can be
// used by itself as well:
//
// https://godoc.org/github.com/globalsign/mgo/bson
//
// For more details, see the documentation for the types and methods.

| -------------- | --------------------- | ----------------- | --------------------- |
| LruCache | lcw.NewLruCache | keys=1000 | LRU cache with limits |
| ExpirableCache | lcw.NewExpirableCache | keys=1000, ttl=5m | TTL cache with limits |

| ExpirableCache | lcw.NewExpirableCache | keys=1000, ttl=5m | TTL cache with limits |
| RedisCache | lcw.NewRedisCache | ttl=5m | Redis cache with limits |
| Nop | lcw.NewNopCache | | Do-nothing cache |
Main features:
- LoadingCache (guava style)
- Limit maximum cache size (in bytes)
- Limit maximum key size
- Limit maximum size of a value
- Limit maximum size of a value
- Limit number of keys
- TTL support (`ExpirableCache` only)
- Callback on eviction event
- TTL support (`ExpirableCache` and `RedisCache`)
- Callback on eviction event (not supported in `RedisCache`)
- Functional style invalidation
- Functional options
- Sane defaults

### Cache with URI
Cache can be created with URIs:
- `mem://lru?max_key_size=10&max_val_size=1024&max_keys=50&max_cache_size=64000` - creates LRU cache with given limits
- `mem://expirable?ttl=30s&max_key_size=10&max_val_size=1024&max_keys=50&max_cache_size=64000` - create expirable cache
- `redis://10.0.0.1:1234?db=16&password=qwerty&network=tcp4&dial_timeout=1s&read_timeout=5s&write_timeout=3s` - create redis cache
- `nop://` - create Nop cache
## Details
- All byte-size limits (MaxCacheSize and MaxValSize) only work for values implementing `lcw.Sizer` interface.

# Mongo [![Build Status](https://travis-ci.org/go-pkgz/mongo.svg?branch=master)](https://travis-ci.org/go-pkgz/mongo) [![Go Report Card](https://goreportcard.com/badge/github.com/go-pkgz/mongo)](https://goreportcard.com/report/github.com/go-pkgz/mongo) [![Coverage Status](https://coveralls.io/repos/github/go-pkgz/mongo/badge.svg?branch=master)](https://coveralls.io/github/go-pkgz/mongo?branch=master)
Provides helpers on top of [mgo](https://github.com/globalsign/mgo)
## Install and update
`go get -u github.com/go-pkgz/mongo`
## Usage
- `Server` represents mongo instance and provides session accessor. Application usually creates one server object and uses it for anything needed with this particular mongo host or replica set.
- `Connection` encapsulates session and provides auto-closable wrapper. Each requests runs inside one of With* function makes new mongo session and closes on completion.
- `BufferedWriter` implements buffered writer to mongo. Write method caching internally till it reached buffer size. Flush methods can be called manually at any time.
```golang
m, err := NewServerWithURL("mongodb://127.0.0.1:27017/test?debug=true", 3*time.Second)
if err != nil {
panic("can't make mongo server")
}
type testRecord struct {
Key1 string
Kay2 int
}
err = c.WithCollection(func(coll *mgo.Collection) error { // create session
// insert 100 records
for i := 0; i < 100; i++ {
r := testRecord{
Key1: fmt.Sprintf("key-%02d", i%5),
Key2: i,
}
if e := coll.Insert(r); e != nil {
return e
}
}
return nil
})
```
## Dependencies
- [globalsign/mgo](https://github.com/globalsign/mgo) - mgo mongo driver
- [stretchr/testify/](https://github.com/stretchr/testify) - testing library (test-only dependency)
## Testing
`testing.go` helps to create test for real mongo (not mocks)
- `mongo.MakeTestConnection` creates `mongo.Connection` for url defined in env `MONGO_TEST`. If not defined `mongodb://mongo:27017` used. By default it will use random connection with prefix `test_` in `test` DB.
- `mongo.RemoveTestCollection` - drops collection used by `MakeTestConnection`
- `mongo.RemoveTestCollections` - drops user-defined collections from `test` DB

# Changelog
## v7 WIP
- WrapProcess is replaced with more convenient AddHook that has access to context.Context.
- WithContext now can not be used to create a shallow copy of the client.
- New methods ProcessContext, DoContext, and ExecContext.
- Client respects Context.Deadline when setting net.Conn deadline.
- Client listens on Context.Done while waiting for a connection from the pool and returns an error when context context is cancelled.
- Add PubSub.ChannelWithSubscriptions that sends `*Subscription` in addition to `*Message` to allow detecting reconnections.
- `time.Time` is now marshalled in RFC3339 format. `rdb.Get("foo").Time()` helper is added to parse time.
## v6.15
- Cluster and Ring pipelines process commands for each node in its own goroutine.
## 6.14
- Added Options.MinIdleConns.
- Added Options.MaxConnAge.
- PoolStats.FreeConns is renamed to PoolStats.IdleConns.
- Add Client.Do to simplify creating custom commands.
- Add Cmd.String, Cmd.Int, Cmd.Int64, Cmd.Uint64, Cmd.Float64, and Cmd.Bool helpers.
- Lower memory usage.
## v6.13
- Ring got new options called `HashReplicas` and `Hash`. It is recommended to set `HashReplicas = 1000` for better keys distribution between shards.
- Cluster client was optimized to use much less memory when reloading cluster state.
- PubSub.ReceiveMessage is re-worked to not use ReceiveTimeout so it does not lose data when timeout occurres. In most cases it is recommended to use PubSub.Channel instead.
- Dialer.KeepAlive is set to 5 minutes by default.
## v6.12
- ClusterClient got new option called `ClusterSlots` which allows to build cluster of normal Redis Servers that don't have cluster mode enabled. See https://godoc.org/github.com/go-redis/redis#example-NewClusterClient--ManualSetup
