client: regenerate sources for etcd/client with new codec version
Major updates to ugorji/go changed the signature of some methods, resulting in the build failing for etcd/client with default installation of the codec. We regenerate the sources using codecgen with the new version to reflect on the new changes. Fixes #8573 Signed-off-by: Alexandre Beslic <abeslic@abronan.com>

To install:

go get github.com/ugorji/go/codec
|
||||
|
||||
This package understands the 'unsafe' tag, to allow using unsafe semantics:
|
||||
|
||||
- When decoding into a struct, you need to read the field name as a string
|
||||
so you can find the struct field it is mapped to.
|
||||
Using `unsafe` will bypass the allocation and copying overhead of []byte->string conversion.
|
||||
|
||||
To install using unsafe, pass the 'unsafe' tag:
|
||||
|
||||
go get -tags=unsafe github.com/ugorji/go/codec
|
||||
This package will carefully use 'unsafe' for performance reasons in specific places.
|
||||
You can build without unsafe use by passing the safe or appengine tag
|
||||
i.e. 'go install -tags=safe ...'. Note that unsafe is only supported for the last 3
|
||||
go sdk versions e.g. current go release is go 1.9, so we support unsafe use only from
|
||||
go 1.7+ . This is because supporting unsafe requires knowledge of implementation details.
|
||||
|
||||

/*
|
||||
|
||||
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:"xid|http://ugorji.net/x-namespace id,omitempty,toarray,attr,cdata"
|
||||
}
|
||||
|
||||
Based on this, we encode
|
||||
- fields as elements, BUT encode as attributes if struct tag contains ",attr".
|
||||
- text as entity-escaped text, BUT encode as CDATA if struct tag contains ",cdata".
|
||||
|
||||
In this mode, we only encode as attribute if ",attr" is found, and only encode as CDATA
|
||||
if ",cdata" is found in the struct tag.
|
||||
|
||||
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
|
||||
- add *Decoder.getStructFieldInfo(encName string) // encName here is either like abc, or h1:nsabc
|
||||
No one accesses .encName anymore except in
|
||||
- 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("nsabc"): x.abc()
|
||||
default: panic(...)
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
The structure below accomodates 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.
|
||||
|
||||
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 continously 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 accomodates 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 { // Prefered. 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
|
||||
Value string
|
||||
}
|
||||
// Element is a ValueObject: There are no accessor methods.
|
||||
// Make element self-contained.
|
||||
type Element struct {
|
||||
Name Name
|
||||
attrsMap map[string]string // where key is "Space Local"
|
||||
attrs []Attr
|
||||
childrenT []string
|
||||
childrenE []Element
|
||||
childrenI []int // each child is a index into T or E.
|
||||
}
|
||||
func (x *Element) child(i) interface{} // returns string or *Element
|
||||
|
||||
Per XML spec and our default handling, white space is insignificant between elements,
|
||||
specifically between parent-child or siblings. White space occuring alone between start
|
||||
and end element IS significant. However, if xml:space='preserve', then we 'preserve'
|
||||
all whitespace. This is more critical when doing a DecodeNaked, but MAY not be as critical
|
||||
when decoding into a typed value.
|
||||
|
||||
**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 don't add any prettifying markup (indenting, etc).
|
||||
|
||||
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 as attributes
|
||||
}
|
||||
|
||||
Question:
|
||||
- if encoding a map, what if map keys have spaces in them???
|
||||
Then they cannot be attributes or child elements. Error.
|
||||
|
||||
Misc:
|
||||
|
||||
- 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).
