2017-03-21encoding/gob: document the extra byte after a singletonRob Pike
This paragraph has been added, as the notion was missing from the documentation. If a value is passed to Encode and the type is not a struct (or pointer to struct, etc.), for simplicity of processing it is represented as a struct of one field. The only visible effect of this is to encode a zero byte after the value, just as after the last field of an encoded struct, so that the decode algorithm knows when the top-level value is complete.

2017-03-13encoding/gob: add Encode-Decode Int slices testsAlberto Donizetti
Tinkering with the gob package shows that is currently possible to *completely destroy* Int slices encoding without triggering a single test failure. The various encInt{8,16,32,64}Slice methods are only called during the execution of the GobMapInterfaceEncode test, which only encodes a few slices of length exactly 1 and then just checks that the error returned by Encode is nil (without trying to Decode back the data). This patch adds a few tests for signed integer slices encoding.

2017-02-14encoding/xml: fix incorrect indirect code in chardata, comment, innerxml fieldsRuss Cox
The new tests in this CL have been checked against Go 1.7 as well and all pass in Go 1.7, with the one exception noted in a comment (an intentional change to omitempty already present before this CL). CL 15684 made the intentional change to omitempty. This CL fixes bugs introduced along the way. Most of these are corner cases that are arguably not that important, but they've always worked all the way back to Go 1, and someone cared enough to file #19063. The most significant problem found while adding tests is that in the case of a nil *string field with `xml:",chardata"`, the existing code silently stops processing not just that field but the entire remainder of the struct. Even if #19063 were not worth fixing, this chardata bug would be. Fixes #19063.

Even for direct PutUint16 benchmark the looping adds overhead and lowers visible benefit. For code-generated encoders / decoders actual effect is more than 20% ) Adding Uint32 and Uint64 raw benchmarks too for completeness. NOTE I had to adjust load-combining rule for bswap case to match first 2 bytes loads as result of "2-bytes load+shift" -> "loadw + rorw 8" rewrite. Reason is: for loads+shift, even e.g. into uint16 var var b []byte var v uin16 v = uint16(b[1]) | uint16(b[0])<<8 the compiler eventually generates L(ong) shift - SHLLconst [8], probably because it is more straightforward / other reasons to work on the whole register. This way 2 bytes rewriting rule is using SHLLconst (not SHLWconst) in its pattern, and then it always gets matched first, even if 2-byte rule comes syntactically after 4-byte rule in AMD64.rules because 4-bytes rule seemingly needs more applyRewrite() cycles to trigger. If 2-bytes rule gets matched for inner half of var b []byte var v uin32 v = uint32(b[3]) | uint32(b[2])<<8 | uint32(b[1])<<16 | uint32(b[0])<<24 and we keep 4-byte load rule unchanged, the result will be MOVW + RORW $8 and then series of byte loads and shifts - not one MOVL + BSWAPL. There is no such problem for stores: there compiler, since it probably knows store destination is 2 bytes wide, uses SHRWconst 8 (not SHRLconst 8) and thus 2-byte store rule is not a subset of rule for 4-byte stores.

Specifically, an Unmarshaler will be given the literal null and can decide what to do (because otherwise json.RawMessage is impossible to implement), and a TextUnmarshaler will be skipped over (because there is no text to unmarshal), like most other inappropriate types. Document this in Unmarshal, with a reminder in UnmarshalJSON about handling null. 2. Test all this. 3. Fix the TextUnmarshaler case, which was returning an unmarshalling error, to match the definition. 4. Fix the error that had been used for the TextUnmarshaler, since it was claiming that there was a JSON string when in fact the problem was NOT having a string. 5. Adjust time.Time and big.Int's UnmarshalJSON to ignore null, as is conventional. Fixes #9037.

There was an inconsistency between the (json encoding + documentation) and the xml encoding implementation. Pointer to an empty value was not being serialized (i.e simply ignored).

2016-10-05encoding/json: use standard ES6 formatting for numbers during marshalRuss Cox
Change float32/float64 formatting to use non-exponential form for a slightly wider range, to more closely match ES6 JSON.stringify and other JSON generators. Most notably: 1e20 now formats as 100000000000000000000 (previously 1e+20) 1e-6 now formats as 0.000001 (previously 1e-06) 1e-7 now formats as 1e-7 (previously 1e-07) This also brings the int64 and float64 formatting in line with each other, for all shared representable values. For example both int64(1234567) and float64(1234567) now format as "1234567", where before the float64 formatted as "1.234567e+06". The only variation now compared to ES6 JSON.stringify is that Go continues to encode negative zero as "-0", not "0", so that the value continues to be preserved during JSON round trips. Fixes #6384. Fixes #14135. Change-Id: Ib0e0e009cd9181d75edc0424a28fe776bcc5bbf8 Reviewed-on: https://go-review.googlesource.com/30371 Reviewed-by: Brad Fitzpatrick <bradfitz@golang.org>
