2020-10-20all: update references to symbols moved from io/ioutil to ioRuss Cox
The old ioutil references are still valid, but update our code to reflect best practices and get used to the new locations. Code compiled with the bootstrap toolchain (cmd/asm, cmd/dist, cmd/compile, debug/elf) must remain Go 1.4-compatible and is excluded. Also excluded vendored code. For #41190.

2019-05-21all: remove PEM-encoded private keys from testsRuss Cox
Gerrit is complaining about pushes that affect these files and forcing people to use -o nokeycheck, which defeats the point of the check. Hide the keys from this kind of scan by marking them explicitly as testing keys. This is a little annoying but better than training everyone who ever edits one of these test files to reflexively override the Gerrit check. The only remaining keys explicitly marked as private instead of testing are in examples, and there's not much to do about those. Hopefully they are not edited as much.

encoding/base64 already skips \r and \n when decoding, so this package must only deal with spaces and tabs.

2017-12-06encoding/pem: change Encode, EncodeToMemory not to generate partial PEM blocksRuss Cox
Originally these routines could not fail except by returning errors from the underlying writer. Then we realized that header keys containing colons needed to be rejected, and we started returning an error from Encode. But that only happens after writing a partial PEM block to the underlying writer, which is unfortunate, but at least it was undocumented. CL 77790 then documented this unfortunate behavior. Instead of documenting unfortunate behavior, fix it.

2015-12-08encoding/pem: make TestFuzz testing/quick safeMatt T. Proud
This adapts pem.TestFuzz to sanitize the generated Block fields, because the encoder and wireformat do not differentiate between nil and empty slices and maps, while reflect.DeepEqual rightfully does. In the commit mentioned below, we adapt quick.Value in testing/quick to generate these value states, which had heretofore been impossible with the standard library fuzz test facility. This commit is a piecemeal extraction from ... https://go-review.googlesource.com/#/c/16470 ..., which rsc requested to be separated from the nil slice and map generations.

2015-06-08testing/quick: probabilistically generate nil pointersHåvard Haugen
The documentation for quick.Value says that it "returns an arbitrary value of the given type." In spite of this, nil values for pointers were never generated, which seems more like an oversight than an intentional choice. The lack of nil values meant that testing recursive type like type Node struct { Next *Node } with testing/quick would lead to a stack overflow since the data structure would never terminate. This change may break tests that don't check for nil with pointers returned from quick.Value. Two such instances were found in the standard library, one of which was in the testing/quick package itself. Fixes #8818.

2015-05-31encoding/pem: be more permissive about decoding empty blocks.Adam Langley
As noted in bug #10980, an empty PEM block is encoded as -----BEGIN foo----- -----END foo----- However, Decode failed to process this. RFC 1421 doesn't answer what the encoding of the empty block should be because PEM messages always contain at least one header. However, PEM these days is just the encoding format – nobody uses the rest of PEM any longer. Having the empty block not contain a newline seems most correct because https://tools.ietf.org/html/rfc1421#section-9 clearly says that the optional “pemtext” carries the leading new-line with it. So if omitted, the new-line should be omitted too. None the less, this changes makes encoding/pem permissive, accepting any number of blank lines in an empty PEM block.
