Dmitri Shuralyov ee379d2b08 all: treat all files as binary, but check in .bat with CRLF
This is a followup to CL 96495.

It should be simpler and more robust to achieve .bat files having
CRLF line endings by treating it as a binary file, like all other
files, and checking it in with the desired CRLF line endings.

A test is used to check the entire Go tree, short of directories
starting with "." and named "testdata", for any .bat files that
have anything other than strict CRLF line endings. This will help
catch any accidental modifications to existing .bat files or check
ins of new .bat files.

Importantly, this is compatible with how Gerrit serves .tar.gz files,
making it so that CRLF line endings are preserved.

The Go project is supported on many different environments, some of
which may have limited git implementations available, or none at all.
Relying on fewer git features and special rules makes it easier to
have confidence in the exact content of all files. Additionally, Go
development started in Subversion, moved to Perforce, then Mercurial,
and now uses Git.¹ Reducing its reliance on git-specific features will
help if there will be another transition in the project's future.

There are only 5 .bat files in the entire Go source tree, so a new one
being added is a rare event, and we prefer to do things in Go instead.
We still have the option of improving the experience for developers by
adding a pre-commit converter for .bat files to the git-codereview tool.

Daniel Martí 5c6b2b14db doc/go1.15: document two noteworthy json changes
I had a look at the changes between 1.14 and master, and these are the
only two that seem relevant enough for the changelog.

There was also CL 179337 to reuse values when decoding map elements, but
it got reverted in CL 234559 and is not being included in 1.15.

Updates #37419.

Filippo Valsorda 608cdcaede all: replace usages of whitelist/blacklist and master/slave
There's been plenty of discussion on the usage of these terms in tech.
I'm not trying to have yet another debate. It's clear that there are
people who are hurt by them and who are made to feel unwelcome by their
use due not to technical reasons but to their historical and social
context. That's simply enough reason to replace them.

Anyway, allowlist and blocklist are more self-explanatory than whitelist
and blacklist, so this change has negative cost.

Didn't change vendored, bundled, and minified files. Nearly all changes
are tests or comments, with a couple renames in cmd/link and cmd/oldlink
which are extremely safe. This should be fine to land during the freeze
without even asking for an exception.

Roland Shoemaker 60cbff6f19 crypto/x509: match cgo and Apple behavior in domain fallback of macOS roots
This change makes the direct call darwin loadSystemRoots implementation
match the existing cgo implementation, which in turn _mostly_ matches
the Apple implementation. The main change here is that when
SecTrustSettingsCopyTrustSettings the error is ignored, and can either
cause a fallback to check admin trust settings, or cause the
certificate to be marked kSecTrustSettingsResultUnspecified.

As well as updating the implementation to match the cgo one, this
change also updates the documentation of how the fallbacks work and
how they match the Apple implementations. References are made to the
Apple source where appropriate. This change does not update the
existing comments in the cgo implementation, since the goal is to
delete that code once the direct call implementation is matured.

Cherry Zhang 73dd74a9fe cmd/internal/goobj2: add referenced symbol names to object file
Currently, for symbols defined in other packages and referenced
by index, we don't record its name in the object file, as the
linker doesn't need the name, only the index. As a consequence,
tools like objdump and nm also don't know the referenced symbol
names and cannot dump it properly.

This CL adds referenced symbol names to the object file. So the
object file is self-contained. And tools can retrieve referenced
symbol names properly.

Tools now should work as good for new object files as for old
object files.

This reverts CL 229246.

For new indexed object files, in CL 229246 we added symbol index
to tools (nm, objdump) output. This affects external tools that
parse those outputs. And the added index doesn't look very nice.
In this release we take it out. For future releases we may
introduce a flag to tools (nm, objdump) and optionally dump the
symbol index.

For refererenced (not defined) indexed symbols, currently the
symbol is still referenced only by index, not by name. The next
CL will make the object file self-contained, so tools can dump
the symbol names properly (as before).

For #38875.

Than McIntosh 58f017bcea cmd/{compile,link}: fix problem with DWARF end_sequence ops
During DWARF line table emission in the linker, prior to issuing a
DW_LNE_end_sequence op to mark the end of the line table for a
compilation unit, advance the PC to produce an address beyond the last
text address in the unit (this is required by the DWARF standard).
Because of the way that GDB interprets end-sequence ops, we were
effectively losing the last row in the line table for each unit, which
degraded the debugging experience.

This problem has been around for a while, but has surfaced recently
due to changes in line table generation. Prior to Go 1.14, the DWARF
line table was emitted entirely in the linker, and a single monolithic
line table was created for each Go package (including functions from
assembly). In 1.14 we moved to having the compiler emit line table
fragments for each function, and having the linker stitch together the
fragments. As part of this change we moved to a model in which each
"go tool compile/asm" output has its own DWARF line table instance,
meaning that there are many more "end sequence" ops, which made the
problem more visible.

Fixes #38192.

Ian Lance Taylor 9b90491e4a runtime: steal timers from running P's
Previously we did not steal timers from running P's, because that P
should be responsible for running its own timers. However, if the P
is running a CPU-bound G, this can cause measurable delays in running
ready timers. Also, in CL 214185 we avoided taking the timer lock of a P
with no ready timers, which reduces the chances of timer lock contention.

So, if we can't find any ready timers on sleeping P's, try stealing
them from running P's.

change.

Updated runtime-gdb_test.go to include a slice and a channel printing test.

(The straightforward printing of a slicevar doesn't work because
of compiler DWARF problems describing the slicevar, not gdb problems).
