      spec: clarify the difference between &T{} and new(T) · eebb9db0
      Robert Griesemer authored 
      Add a small paragraph and example pointing out
the difference for the case where T is a slice
or map. This is a common error for Go novices.

Fixes #29425.

      spec: clarify language on package-level variable initialization · 451cf3e2
      Robert Griesemer authored 
      The very first paragraph on "Package initialization" stated that
"variables are initialized in declaration order, but after any
variables they might depend on". This phrasing was easily
misread as "declaration order is the first sorting criteria"
and then contradicted what the subsequent paragraphs spelled
out in precise detail.

Instead, variable initialization proceeds by repeatedly determining
a set of ready to initialize variables, and then selecting from that
set the variable declared earliest. That is, declaration order is the
second sorting criteria.

Also, for the purpose of variable initialization, declarations
introducing blank (_) variables are considered like any other
variables (their initialization expressions may have side-effects
and affect initialization order), even though blank identifiers
are not "declared".

This CL adds clarifying language regarding these two issues
and the supporting example.

Both gccgo and go/types implement this behavior. cmd/compile
has a long-standing issue (#22326).

The spec also did not state in which order multiple variables
initialized by a single (multi-value) initialization expression are
handled. This CL adds a clarifying paragraph: If any such variable
is initialized, all that declaration's variables are initialized at
the same time.

This behavior matches user expectation: We are not expecting to
observe partially initialized sets of variables in declarations
such as "var a, b, c = f()".

It also matches existing cmd/compile and go/types (but not gccgo)
behavior.

Finally, cmd/compile, gccgo, and go/types produce different
initialization orders in (esoteric) cases where hidden (not
detected with existing rules) dependencies exist. Added a
sentence and example clarifying how much leeway compilers have
in those situations. The goal is to preserve the ability to
use static initialization while at the same time maintain
the relative initialization order of variables with detected
dependencies.

Fixes   #31292.
Updates #22326.

      cmd/go: make 'go get' match patterns against packages, not modules · 71be83e8
      Jay Conrod authored 
      This is a follow-up to CL 174099, fixing an important TODO.
The 'go help modget' documentation will be clarified in anotehr CL,
pending further discussion.

When invoked without -m, 'go get' will no longer match arguments
containing "..." against module paths. If a module's path matches a
pattern but no packages within the module match the pattern, the
module should not be upgraded. For example, if
golang.org/x/tools/playground and golang.org/x/tools are separate
modules, and only golang.org/x/tools is in the build list,
'go get golang.org/x/tools/playground/...' should add
golang.org/x/tools/playground to the build list and leave
golang.org/x/tools alone.

      index/suffixarray: index 3-10X faster in half the memory · 6ca324f2
      Russ Cox authored 
      This CL changes the index/suffixarray construction algorithm from QSufSort to SAIS.

For an N-byte input, QSufSort runs in O(N log N) time and requires
an N-int temporary work space in addition to the N-int output.

In contrast, SAIS runs in O(N) time and, for essentially all real inputs,
is able to use the N-int output buffer as its temporary work space.
(In pathological cases, SAIS must allocate a temporary work space of
at most N/2 ints. There exist more complex variants that guarantee
to avoid the work space in all cases, but they hardly seem worth the cost
given how rare these pathological cases are.)

The SAIS code therefore uses 50% of the memory across the board.
It also runs 3-10X faster on real input text.

This CL also adds more extensive algorithmic tests, including an
exhaustive test over small inputs to catch corner case problems.

      cmd/go/internal/modfetch: fix GOSUMDB test failures · 5f320f96
      Bryan C. Mills authored 
      Use cfg.GOSUMDB consistently instead of re-resolving it from the environment.

Set cfg.GOSUMDB to 'off' explicitly in coderepo_test, since it may
include modules that cannot be fetched using a released version of the
'go' command.

      mime: update .mjs MIME type from text/ to application/javascript · db2bf154
      Brad Fitzpatrick authored 
      .mjs should be the same MIME type as .js, and RFC 4329 says that
text/javascript is obsolete, even back in 2006:

    https://tools.ietf.org/html/rfc4329#section-7.1

I didn't notice this when I recently reviewed CL 169502.

Also, re-sort it.

      Previous section of documentation said that if GOPATH is not set then
it will be default to "$HOME/go", not "$HOME/work".

This change fix the path in example code to "$HOME/go", and while at it
fix the output of git command after commit.
