2024-05-23all: change from sort functions to slices functions where feasibleIan Lance Taylor
Doing this because the slices functions are slightly faster and slightly easier to use. It also removes one dependency layer. This CL does not change packages that are used during bootstrap, as the bootstrap compiler does not have the required slices functions. It does not change the go/scanner package because the ErrorList Len, Swap, and Less methods are part of the Go 1 API.

2022-10-04encoding/gob: prevent a decoder state overflowDaniel Martí
When decoding a struct, if a positive delta is large enough to overflow when added to fieldnum, we would panic due to the resulting negative index. Instead, catch this problem and produce an error like we do with negative delta integers. If fieldnum ends up being negative or smaller than state.fieldnum, the addition overflowed. While here, remove an unnecessary break after an error call, since those error functions cause a panic. Fixes #55337.

2021-12-13all: gofmt -w -r 'interface{} -> any' srcRuss Cox
And then revert the bootstrap cmd directories and certain testdata. And adjust tests as needed. Not reverting the changes in std that are bootstrapped, because some of those changes would appear in API docs, and we want to use any consistently. Instead, rewrite 'any' to 'interface{}' in cmd/dist for those directories when preparing the bootstrap copy. A few files changed as a result of running gofmt -w not because of interface{} -> any but because they hadn't been updated for the new //go:build lines. Fixes #49884.

2021-10-11encoding/gob: follow documented io.EOF semanticsDaniel Martí
The docs say: If the input is at EOF, Decode returns io.EOF and does not modify e. However, the added test fails: --- FAIL: TestDecodePartial (0.00s) encoder_test.go:1263: 31/81: expected io.ErrUnexpectedEOF: EOF encoder_test.go:1263: 51/81: expected io.ErrUnexpectedEOF: EOF In particular, the decoder would return io.EOF after reading a valid message for a type specification, and then hit EOF before reading a data item message. Fix that by only allowing a Decode call to return io.EOF if the reader hits EOF immediately, without successfully reading any message. Otherwise, hitting EOF is an ErrUnexpectedEOF, like in other cases. Also fix a net/rpc test that, coincidentally, expected an io.EOF as an error when feeding bad non-zero data to a gob decoder. An io.ErrUnexpectedEOF is clearly better in that scenario. Fixes #48905.

The general policy for the current state of js/wasm is that it only has to support tests that are also supported by nacl. The test nilptr3.go makes assumptions about which nil checks can be removed. Since WebAssembly does not signal on reading a null pointer, all nil checks have to be explicit.

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.

2016-08-19encoding/gob: error out instead of panicking on nil dereferenceEmmanuel Odeke
Do not panic when we encounter nil interface values which are invalid values for gob. Previously this wasn't caught yet we were calling reflect.*.Type() on reflect.Invalid values thereby causing panic: `panic: reflect: call of reflect.Value.Type on zero Value.` which is a panic not enforced by encoding/gob itself. We can catch this and send back an error to the caller.
