      Derek Shockey authored 
      Looks like this was intended to match a literal period to restrict
this to `.go` files, but in POSIX grep, the unescaped period matches
any character.

      cmd/go: better error for test functions with wrong signature · c2d3e112
      Caio Marcelo de Oliveira Filho authored 
      Check the function types before compiling the tests. Extend the same
approach taken by the type check used for TestMain function.

To keep existing behavior, wrong arguments for TestMain are ignored
instead of causing an error.

Fixes #14226.

      sync/atomic: reduce test in short mode · e1035c5e
      Dmitry Vyukov authored 
      In normal mode the test runs for 9+ seconds on my machine (48 cores).
But the real problem is race mode, in race mode it hits 10m test timeout.
Reduce test size in short mode. Now it runs for 100ms without race.

      net/url: support query string without values · 9f26170a
      Rick Arnold authored 
      Previously, RawQuery was used to indicate the presence of a query
string in url.URL. However, this approach was not able to differentiate
between URLs that have no query string at all (http://foo.bar/) and
those that have a query with no values (http://foo.bar/?).

Add a ForceQuery field to indicate the latter form of URL and use it
in URL.String to create a matching URL with a trailing '?'.

Fixes #13488

      runtime: unwire g/m in dropg always · bdc14698
      Dmitry Vyukov authored 
      Currently dropg does not unwire locked g/m.
This is unnecessary distiction between locked and non-locked g/m.
We always restart goroutines with execute which re-wires g/m.

First, this produces false sense that this distinction is necessary.
Second, it can confuse some sanity and cross checks. For example,
if we check that g/m are unwired before we wire them in execute,
the check will fail for locked g/m. I've hit this while doing some
race detector changes, When we deschedule a goroutine and run
scheduler code, m.curg is generally nil, but not for locked ms.

Remove the distinction.

      runtime: remove workbuf logging · 3b3d58e1
      Austin Clements authored 
      Early in Go 1.5 we had bugs with ownership of workbufs, so we added a
system for tracing their ownership to help debug these issues.
However, this system has both CPU and space overhead even when
disabled, it clutters up the workbuf API, the higher level gcWork
abstraction makes it very difficult to mess up the ownership of
workbufs in practice, and the tracing hasn't been enabled or needed
since 5b66e5d0 nine months ago. Hence, remove it.

Benchmarks show the usual noise from changes at this level, but little
overall movement.

      cmd/compile: simplify error sorting · a5b7a8d6
      Matthew Dempsky authored 
      Errors have unique seq values (their index within the errors slice),
so errcmp never needs to fallback to sorting by message text.
Moreover, comparing by original index is exactly the purpose of using
a stable sort algorithm (and sort.Stable was added in Go 1.2), so we
really only need to compare by lineno.

      cmd/compile: rationalize (lex)?lineno handling · e0fa809f
      Matthew Dempsky authored 
      Previously, many error messages inconsistantly used either lexlineno
and lineno.  In general this works out okay because they're almost
always the same.  The only exceptional case is after lexing a
multi-line raw string literal, where lineno will be the line number of
the opening quote and lexlineno is the line number of the closing
quote.

This CL makes the compiler's error message more consistent:

- Lexer error messages related to invalid byte sequences (i.e., NUL
bytes, bad UTF-8 sequences, and non-initial BOMs) are emitted at
lexlineno (i.e., the source line that contains the invalid byte
sequence).

- All other error messages (notably the parser's "syntax errors") now
use lineno.  The minor change from this is that bogus input like:

    package `
    bogus`

will emit "syntax error: unexpected string literal, expecting name"
error at line 1, instead of line 2.

- Instead of maintaining prevlineno all the time, just record it
when/where actually needed and not already available elsewhere (which
turns out to be just one function).

- Lastly, we remove the legacy "syntax error near ..." fallback in
Yerror, now that the parser always emits more detailed syntax error
messages.
