Dave Cheney authored Dec 12, 2012

Fixes #4079.

Some example output:

can't load package: package foo/bar: cannot find package "foo/bar" in any of:
        /home/dfc/go/src/pkg/foo/bar (from $GOROOT)
        /home/dfc/src/foo/bar (from $GOPATH)
        /home/dfc/src2/src/foo/bar

% GOPATH= go install foo/bar
can't load package: package foo/bar: cannot find package "foo/bar" in any of:
	/home/dfc/go/src/pkg/foo/bar (from $GOROOT)
	($GOPATH not set)

cmd/6g, cmd/8g: simplify integer division code. · a617d062

Rémy Oudompheng authored Dec 12, 2012

Change suggested by iant. The compiler generates
special code for a/b when a is -0x80...0 and b = -1.
A single instruction can cover the case where b is -1,
so only one comparison is needed.

Fixes #3551.

net/http, net/url: permit Request-URI "*" · a6701f26

Also, implement a global OPTIONS * handler, like Apache.

Permit sending "*" requests to handlers, but not path-based
(ServeMux) handlers.  That means people can go out of their
way to support SSDP or SIP or whatever, but most users will be
unaffected.

spec: consistently use "indices" (rather than "indexes") · 9c9e811b

Robert Griesemer authored Dec 10, 2012

We have been using all three terms "indices", "indexes",
and "index expressions" indiscriminatly for index values.
With this change, "index" refers to an index value,
"indices" is the plural of "index", and "index expression"
refers to an array, slice, or map indexed by an index: a[x].

time: add Round and Truncate · 00cd6a3b

Russ Cox authored Dec 09, 2012

New in Go 1 will be nanosecond precision in the result of time.Now on Linux.
This will break code that stores time in external formats at microsecond
precision, reads it back, and expects to get exactly the same time.

Code like that can be fixed by using time.Now().Round(time.Microsecond)
instead of time.Now() in those contexts.
