// Package redis is a client for the Redis database.
//
// The Redigo FAQ (https://github.com/gomodule/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 bulk 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.Fprint(w, 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}
// psc.Subscribe("example")
// for {
// switch v := psc.Receive().(type) {
// case redis.Message:
// fmt.Printf("%s: message: %s\n", v.Channel, v.Data)
// case redis.Subscription:
// fmt.Printf("%s: %s %d\n", v.Channel, v.Kind, v.Count)
// case error:
// return v
// }
// }
//
// 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.

package codec
/*
A strict Non-validating namespace-aware XML 1.0 parser and (en|de)coder.
We are attempting this due to perceived issues with encoding/xml:
- Complicated. It tried to do too much, and is not as simple to use as json.
- Due to over-engineering, reflection is over-used AND performance suffers:
java is 6X faster:http://fabsk.eu/blog/category/informatique/dev/golang/
even PYTHON performs better: http://outgoing.typepad.com/outgoing/2014/07/exploring-golang.html
codec framework will offer the following benefits
- VASTLY improved performance (when using reflection-mode or codecgen)
- simplicity and consistency: with the rest of the supported formats
- all other benefits of codec framework (streaming, codegeneration, etc)
codec is not a drop-in replacement for encoding/xml.
It is a replacement, based on the simplicity and performance of codec.
Look at it like JAXB for Go.
Challenges:
- Need to output XML preamble, with all namespaces at the right location in the output.
- Each "end" block is dynamic, so we need to maintain a context-aware stack
- How to decide when to use an attribute VS an element
- How to handle chardata, attr, comment EXPLICITLY.
- Should it output fragments?
e.g. encoding a bool should just output true OR false, which is not well-formed XML.
Extend the struct tag. See representative example:
type X struct {
ID uint8 `codec:"http://ugorji.net/x-namespace xid id,omitempty,toarray,attr,cdata"`
// format: [namespace-uri ][namespace-prefix ]local-name, ...
}
Based on this, we encode
- fields as elements, BUT
encode as attributes if struct tag contains ",attr" and is a scalar (bool, number or string)
- text as entity-escaped text, BUT encode as CDATA if struct tag contains ",cdata".
To handle namespaces:
- XMLHandle is denoted as being namespace-aware.
Consequently, we WILL use the ns:name pair to encode and decode if defined, else use the plain name.
- *Encoder and *Decoder know whether the Handle "prefers" namespaces.
- add *Encoder.getEncName(*structFieldInfo).
No one calls *structFieldInfo.indexForEncName directly anymore
- OR better yet: indexForEncName is namespace-aware, and helper.go is all namespace-aware
indexForEncName takes a parameter of the form namespace:local-name OR local-name
- add *Decoder.getStructFieldInfo(encName string) // encName here is either like abc, or h1:nsabc
by being a method on *Decoder, or maybe a method on the Handle itself.
No one accesses .encName anymore
- let encode.go and decode.go use these (for consistency)
- only problem exists for gen.go, where we create a big switch on encName.
Now, we also have to add a switch on strings.endsWith(kName, encNsName)
- gen.go will need to have many more methods, and then double-on the 2 switch loops like:
switch k {
case "abc" : x.abc()
case "def" : x.def()
default {
switch {
case !nsAware: panic(...)
case strings.endsWith(":abc"): x.abc()
case strings.endsWith(":def"): x.def()
default: panic(...)
}
}
}
The structure below accommodates this:
type typeInfo struct {
sfi []*structFieldInfo // sorted by encName
sfins // sorted by namespace
sfia // sorted, to have those with attributes at the top. Needed to write XML appropriately.
sfip // unsorted
}
type structFieldInfo struct {
encName
nsEncName
ns string
attr bool
cdata bool
}
indexForEncName is now an internal helper function that takes a sorted array
(one of ti.sfins or ti.sfi). It is only used by *Encoder.getStructFieldInfo(...)
There will be a separate parser from the builder.
The parser will have a method: next() xmlToken method. It has lookahead support,
so you can pop multiple tokens, make a determination, and push them back in the order popped.
This will be needed to determine whether we are "nakedly" decoding a container or not.
The stack will be implemented using a slice and push/pop happens at the [0] element.
xmlToken has fields:
- type uint8: 0 | ElementStart | ElementEnd | AttrKey | AttrVal | Text
- value string
- ns string
SEE: http://www.xml.com/pub/a/98/10/guide0.html?page=3#ENTDECL
The following are skipped when parsing:
- External Entities (from external file)
- Notation Declaration e.g. <!NOTATION GIF87A SYSTEM "GIF">
- Entity Declarations & References
- XML Declaration (assume UTF-8)
- XML Directive i.e. <! ... >
- Other Declarations: Notation, etc.
- Comment
- Processing Instruction
- schema / DTD for validation:
We are not a VALIDATING parser. Validation is done elsewhere.
However, some parts of the DTD internal subset are used (SEE BELOW).
For Attribute List Declarations e.g.
<!ATTLIST foo:oldjoke name ID #REQUIRED label CDATA #IMPLIED status ( funny | notfunny ) 'funny' >
We considered using the ATTLIST to get "default" value, but not to validate the contents. (VETOED)
The following XML features are supported
- Namespace
- Element
- Attribute
- cdata
- Unicode escape
The following DTD (when as an internal sub-set) features are supported:
- Internal Entities e.g.
<!ELEMENT burns "ugorji is cool" > AND entities for the set: [<>&"']
- Parameter entities e.g.
<!ENTITY % personcontent "ugorji is cool"> <!ELEMENT burns (%personcontent;)*>
At decode time, a structure containing the following is kept
- namespace mapping
- default attribute values
- all internal entities (<>&"' and others written in the document)
When decode starts, it parses XML namespace declarations and creates a map in the
xmlDecDriver. While parsing, that map continuously gets updated.
The only problem happens when a namespace declaration happens on the node that it defines.
e.g. <hn:name xmlns:hn="http://www.ugorji.net" >
To handle this, each Element must be fully parsed at a time,
even if it amounts to multiple tokens which are returned one at a time on request.
xmlns is a special attribute name.
- It is used to define namespaces, including the default
- It is never returned as an AttrKey or AttrVal.
*We may decide later to allow user to use it e.g. you want to parse the xmlns mappings into a field.*
Number, bool, null, mapKey, etc can all be decoded from any xmlToken.
This accommodates map[int]string for example.
It should be possible to create a schema from the types,
or vice versa (generate types from schema with appropriate tags).
This is however out-of-scope from this parsing project.
We should write all namespace information at the first point that it is referenced in the tree,
and use the mapping for all child nodes and attributes. This means that state is maintained
at a point in the tree. This also means that calls to Decode or MustDecode will reset some state.
When decoding, it is important to keep track of entity references and default attribute values.
It seems these can only be stored in the DTD components. We should honor them when decoding.
Configuration for XMLHandle will look like this:
XMLHandle
DefaultNS string
// Encoding:
NS map[string]string // ns URI to key, used for encoding
// Decoding: in case ENTITY declared in external schema or dtd, store info needed here
Entities map[string]string // map of entity rep to character
During encode, if a namespace mapping is not defined for a namespace found on a struct,
then we create a mapping for it using nsN (where N is 1..1000000, and doesn't conflict
with any other namespace mapping).
Note that different fields in a struct can have different namespaces.
However, all fields will default to the namespace on the _struct field (if defined).
An XML document is a name, a map of attributes and a list of children.
Consequently, we cannot "DecodeNaked" into a map[string]interface{} (for example).
We have to "DecodeNaked" into something that resembles XML data.
To support DecodeNaked (decode into nil interface{}), we have to define some "supporting" types:
type Name struct { // Preferred. Less allocations due to conversions.
Local string
Space string
}
type Element struct {
Name Name
Attrs map[Name]string
Children []interface{} // each child is either *Element or string
}
Only two "supporting" types are exposed for XML: Name and Element.
// ------------------
We considered 'type Name string' where Name is like "Space Local" (space-separated).
We decided against it, because each creation of a name would lead to
double allocation (first convert []byte to string, then concatenate them into a string).
The benefit is that it is faster to read Attrs from a map. But given that Element is a value
object, we want to eschew methods and have public exposed variables.
We also considered the following, where xml types were not value objects, and we used
intelligent accessor methods to extract information and for performance.
*** WE DECIDED AGAINST THIS. ***
type Attr struct {
Name Name

// ------------------
Per XML spec and our default handling, white space is always treated as
insignificant between elements, except in a text node. The xml:space='preserve'
attribute is ignored.
**Note: there is no xml: namespace. The xml: attributes were defined before namespaces.**
**So treat them as just "directives" that should be interpreted to mean something**.
On encoding, we support indenting aka prettifying markup in the same way we support it for json.
A document or element can only be encoded/decoded from/to a struct. In this mode:
- struct name maps to element name (or tag-info from _struct field)
- fields are mapped to child elements or attributes
A map is either encoded as attributes on current element, or as a set of child elements.
Maps are encoded as attributes iff their keys and values are primitives (number, bool, string).
A list is encoded as a set of child elements.
Primitives (number, bool, string) are encoded as an element, attribute or text
depending on the context.
Extensions must encode themselves as a text string.
Encoding is tough, specifically when encoding mappings, because we need to encode
as either attribute or element. To do this, we need to default to encoding as attributes,
and then let Encoder inform the Handle when to start encoding as nodes.
i.e. Encoder does something like:
h.EncodeMapStart()
h.Encode(), h.Encode(), ...
h.EncodeMapNotAttrSignal() // this is not a bool, because it's a signal
h.Encode(), h.Encode(), ...
h.EncodeEnd()
Only XMLHandle understands this, and will set itself to start encoding as elements.
This support extends to maps. For example, if a struct field is a map, and it has
the struct tag signifying it should be attr, then all its fields are encoded as attributes.
e.g.
type X struct {
M map[string]int `codec:"m,attr"` // encode keys as attributes named
}
Question:
- if encoding a map, what if map keys have spaces in them???
Then they cannot be attributes or child elements. Error.
Options to consider adding later:
- For attribute values, normalize by trimming beginning and ending white space,
and converting every white space sequence to a single space.
- ATTLIST restrictions are enforced.
e.g. default value of xml:space, skipping xml:XYZ style attributes, etc.
- Consider supporting NON-STRICT mode (e.g. to handle HTML parsing).
Some elements e.g. br, hr, etc need not close and should be auto-closed
... (see http://www.w3.org/TR/html4/loose.dtd)
An expansive set of entities are pre-defined.
- Have easy way to create a HTML parser:
add a HTML() method to XMLHandle, that will set Strict=false, specify AutoClose,
and add HTML Entities to the list.
- Support validating element/attribute XMLName before writing it.
Keep this behind a flag, which is set to false by default (for performance).
type XMLHandle struct {
CheckName bool
}
Misc:
ROADMAP (1 weeks):
- build encoder (1 day)
- build decoder (based off xmlParser) (1 day)
- implement xmlParser (2 days).
Look at encoding/xml for inspiration.
- integrate and TEST (1 days)
- write article and post it (1 day)
// ---------- MORE NOTES FROM 2017-11-30 ------------
when parsing
- parse the attributes first
- then parse the nodes
basically:
- if encoding a field: we use the field name for the wrapper
- if encoding a non-field, then just use the element type name
map[string]string ==> <map><key>abc</key><value>val</value></map>... or
<map key="abc">val</map>... OR
<key1>val1</key1><key2>val2</key2>... <- PREFERED
[]string ==> <string>v1</string><string>v2</string>...
string v1 ==> <string>v1</string>
bool true ==> <bool>true</bool>
float 1.0 ==> <float>1.0</float>
...
F1 map[string]string ==> <F1><key>abc</key><value>val</value></F1>... OR
<F1 key="abc">val</F1>... OR
<F1><abc>val</abc>...</F1> <- PREFERED
F2 []string ==> <F2>v1</F2><F2>v2</F2>...
F3 bool ==> <F3>true</F3>
...
- a scalar is encoded as:
(value) of type T ==> <T><value/></T>
(value) of field F ==> <F><value/></F>
- A kv-pair is encoded as:
(key,value) ==> <map><key><value/></key></map> OR <map key="value">
(key,value) of field F ==> <F><key><value/></key></F> OR <F key="value">
- A map or struct is just a list of kv-pairs
- A list is encoded as sequences of same node e.g.
<F1 key1="value11">
<F1 key2="value12">
<F2>value21</F2>
<F2>value22</F2>
- we may have to singularize the field name, when entering into xml,
and pluralize them when encoding.
- bi-directional encode->decode->encode is not a MUST.
even encoding/xml cannot decode correctly what was encoded:

This program reads a file containing function prototypes
(like syscall_solaris.go) and generates system call bodies.
The prototypes are marked by lines beginning with "//sys"
and read like func declarations if //sys is replaced by func, but:
* The parameter lists must give a name for each argument.
This includes return parameters.
* The parameter lists must give a type for each argument:
the (x, y, z int) shorthand is not allowed.
* If the return parameter is an error number, it must be named err.
* If go func name needs to be different than its libc name,
* or the function is not in libc, name could be specified
* at the end, after "=" sign, like
//sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
