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.

This fixes a regression where only CRLF was folded into LF at EOF.
Now, we also truncate trailing CR at EOF to preserve the old behavior.
Every one of the test cases added exactly matches the behavior
of Go1.9, even if the results are somewhat unexpected.

This reverts commit 08f19bbde1b01227fdc2fa2d326e4029bb74dd96.
Reason for revert:
The changed transformation takes effect on a larger set
of code snippets than expected.
For example, this:
func foo() {
// Comment
bar()
}
becomes:
func foo() {
// Comment
bar()
}
This is an unintended consequence.

CL 52810 changed Reader to interpret a quoted \r\n as a raw \r\n
when reading fields. This seems likely to break existing users, and
discussion on both #21201 (the original issue that triggered the change)
and #22746 (discussing whether to revert the change) failed to identify
a single motivating example for this change. To avoid breaking existing
users for no clear reason, revert the change.
The Reader has been rewritten in the interim so this is not a git revert
but instead and adjustment (and slight simplification) of the new Reader.
Fixes #22746.

and errors
CL 70210 added Decoder for #21590, and in doing so it changed
the existing func Decode to return partial results for decoding errors.
That seems like a good change to make to Decode, but it was
untested (except as used by Decoder), inconsistent with DecodeString
in all error cases, and inconsistent with Decoder in not returning
partial results for odd-length input strings.
This CL makes Decode, DecodeString, and Decoder all agree about
the handling of partial results (they are returned) and error
precedence (the error earliest in the input is reported),
and it documents and tests this.

CL 58210 introduced this constant for reasons I don't understand.
It should not be in the exported const block, which will pollute
godoc output with a "... unexported" notice.
Also since we already have a constant named xmlnsPrefix for "xmlns",
it is very confusing to also have xmlNamespacePrefix for "xml".
If we must have the constant at all, rename it to xmlPrefix.

in a tag and in the types XMLName field that an error will occur. This

The go repository contains a mix of github.com/golang/go/issues/xxxxx
and golang.org/issues/xxxxx URLs for references to issues in the issue
tracker. We should use one for consistency, and golang.org is preferred
in case the project moves the issue tracker in the future.
This reasoning is taken from a comment Sam Whited left on a CL I
recently opened: https://go-review.googlesource.com/c/go/+/73890.
In that CL I referenced an issue using its github.com URL, because other
tests in the file I was changing contained references to issues using
their github.com URL. Sam Whited left a comment on the CL stating I
should change it to the golang.org URL.
If new code is intended to reference issues via golang.org and not
github.com, existing code should be updated so that precedence exists
for contributors who are looking at the existing code as a guide for the
code they should write.

This adds new rules to recognize consecutive byte loads and
stores and lowers them to loads and stores such as lhz, lwz, ld,
sth, stw, std. This change only covers the little endian cases
on little endian machines, such as is found in encoding/binary
UintXX or PutUintXX for little endian. Big endian will be done
later.
Updates were also made to binary_test.go to allow the benchmark
for Uint and PutUint to actually use those functions because
the way they were written, those functions were being
optimized out.

CL 72150 fixes #22352 by reverting the problematic parts of that CL
where the line number and column number were inconsistent with each other.
This CL adds back functionality to address the issue that CL 72150
was trying to solve in the first place. That is, it reports the starting
line of the record, so that users have a frame of reference to start with
when debugging what went wrong.
In the event of gnarly CSV files with multiline quoted strings, a parse
failure likely occurs somewhere between the start of the record and
the point where the parser finally detected an error.
Since ParserError.{Line,Column} reports where the *error* occurs, we
add a RecordLine field to report where the record starts.
Also take this time to cleanup and modernize TestRead.

The Reader implementation is slow because it operates on a rune-by-rune
basis via bufio.Reader.ReadRune. We speed this up by operating on entire
lines that we read from bufio.Reader.ReadSlice.
In order to ensure that we read the full line, we augment ReadSlice
in our Reader.readLine method to automatically expand the slice if
bufio.ErrBufferFull is every hit.
This change happens to fix #19410 because it no longer relies on
rune-by-rune parsing and only searches for the relevant delimiter rune.
In order to keep column accounting simple and consistent, this change
reverts parts of CL 52830.
This CL is an alternative to CL 36270 and builds on some of the ideas
from that change by Diogo Pinela.

In #10909, it was decided that "Deprecated:" is a magic string for
tools (e.g., #17056 for godoc) to detect deprecated identifiers.
Use those convention instead of custom written prose.

The '*' character is not allowed in ASN.1 PrintableString. However, due
to wide-spread use, we permit it so that we can parse many certificates
with wildcards. However, that also meant that generic strings with
asterisks in would be encoded as PrintableString.
This change makes the default for such strings to be UTF8String. Thus,
while the code PrintableStrings containing '*', it will not generate
them unless the string type was specified in the struct field tag.

Optimize base64 decoding speed by adding 32-bits and 64-bits specialized
methods that don't perform any error checking and fall back to the more
complex decodeQuantum method when a non-base64 character is present.

Previously, any “explicit” and/or “tag” decorations on a RawValue would
be ignored when unmarshaling. The RawValue would swallow whatever
element was encountered.
This change causes these decorations to be respected. Thus a field like:
Foo asn1.RawValue `asn1:"explicit,tag:1,optional"`
will only match if an explicit tag with value one is encountered.
Otherwise the RawValue will get the default value and parsing will move
onto the next element.
Thanks to Martin Kreichgauer for reporting the issue.

bytes.IndexByte can be used wherever the second argument to
strings.Index is exactly one byte long, so we do that with this change.
This avoids generating unnecessary string symbols/converison and saves
a few calls to bytes.Index.

CL 60410 fixes the compiler such that reflect.StructField.PkgPath
is non-empty if and only if the field is unexported.
Given that property, we can cleanup the logic in the json encoder
to avoid parsing the field name to detect export properties.

Found with mvdan.cc/unindent. It skipped the cases where parentheses
would need to be added, where comments would have to be moved elsewhere,
or where actions and simple logic would mix.
One of them was of the form "err != nil && err == io.EOF", so the first
part was removed.

Most of these are return values that were part of a receiving parameter,
so they're still accessible.
A few others are not, but those have never had a use.
Found with github.com/mvdan/unparam, after Kevin Burke's suggestion that
the tool should also warn about unused result parameters.
