the AST walker currently provides no way to find out how the
...
nodes in the tree are nested with respect to one another.
a simple change to the Visitor interface makes it possible
to do this (for example to maintain a current node-depth, or a
knowledge of the name of the current function).
Visit(nil) is called at the end of a node's children;
this make possible the channel-based interface below,
amongst other possibilities.
It is still just as simple to get the original behaviour - just
return the same Visitor from Visit.
Here are a couple of possible Visitor types.
// closure-based
type FVisitor func(n interface{}) FVisitor
func (f FVisitor) Visit(n interface{}) Visitor {
return f(n);
}
// channel-based
type CVisitor chan Visit;
type Visit struct {
node interface{};
reply chan CVisitor;
};
func (v CVisitor) Visit(n interface{}) Visitor
{
if n == nil {
close(v);
} else {
reply := make(chan CVisitor);
v <- Visit{n, reply};
r := <-reply;
if r == nil {
return nil;
}
return r;
}
return nil;

Make printing faster by avoiding mallocs and some other advances.
...
Roughly 33% faster for simple cases, probably more for complex ones.
Before:
mallocs per Sprintf(""): 4
mallocs per Sprintf("xxx"): 6
mallocs per Sprintf("%x"): 10
mallocs per Sprintf("%x %x"): 12
Now:
mallocs per Sprintf(""): 2
mallocs per Sprintf("xxx"): 3
mallocs per Sprintf("%x"): 5
mallocs per Sprintf("%x %x"): 7
Speed improves because of avoiding mallocs and also by sharing a bytes.Buffer
between print.go and format.go rather than copying the data back after each
printed item.
Before:
fmt_test.BenchmarkSprintfEmpty 1000000 1346 ns/op
fmt_test.BenchmarkSprintfString 500000 3461 ns/op
fmt_test.BenchmarkSprintfInt 500000 3671 ns/op
Now:
fmt_test.BenchmarkSprintfEmpty 2000000 995 ns/op
fmt_test.BenchmarkSprintfString 1000000 2745 ns/op
fmt_test.BenchmarkSprintfInt 1000000 2391 ns/op
fmt_test.BenchmarkSprintfIntInt 500000 3751 ns/op
I believe there is more to get but this is a good milestone.

Add flag -tabindent to gofmt: forces use of
...
tabs for indentation even if -spaces is set.
Changes to gofmt:
- added -tabindent flag
- don't recompute parser and printer mode repeatedly
Changes to go/printer:
- provide new printing mode TabIndent
Changes to tabwriter:
- implement new mode TabIndent to use tabs independent
of the actual padding character for leading empty columns
- distinguish between minimal cell width and tab width
(tabwidth is only used if the output contains tabs,
minwidth and padding are always considered)
- fixed and added more comments
- some additional factoring
By default, -tabindent is disabled and the default gofmt
behavior is unchanged. By setting -spaces and -tabindent,
gofmt will use tabs for indentation but do any other
alignment with spaces. This permits a user to change the
visible indentation by simply changing the editor's tab
width and the code will remain properly aligned without
the need to rerun gofmt.

Map support for template.Execute().
...
Allows the developer to pass a map either by itself for
evaluation, or inside a struct. Access to data inside
maps is identical to the current system for structs, ie.
-Psuedocode-
mp map[string]string = {
"header" : "A fantastic header!",
"footer" : "A not-so-fantastic footer!",
}
template.Execute(mp)
...can be accessed using {header} and {footer} in
the template. Similarly, for maps inside structs:
type s struct {
mp map[string]string,
}
s1 = new s
s1.mp["header"] = "A fantastic header!";
template.Execute(s1)
...is accessed using {mp.header}. Multi-maps, ie.
map[string](map[string]string) and maps of structs
containing more maps are unsupported, but then, I'm
not even sure if that's supported by the language.
Map elements can be of any type that can be written
by the formatters. Keys should really only be strings.

net: remove race condition on Close.
...
Previously a netFd could be queued for reading/writing in the channel,
but close(2)'ed before pollServer got to it. In this case, the kernel
would consider the descriptor closed and the attempt to add it to the
epoll set would fail and panic.
This patch makes Close a roundtrip to the pollServer, although the
actual close(2) still occurs elsewhere to avoid blocking the
pollServer.

Make non-errored RPC calls return 'nil' error to caller.
...
Error information is carried from RPC server to client in the string
'Error' field of rpc.Response. An empty string is sent in the success
case. This empty string was being returned to the caller (of Client.Call
or Client.Go), resulting in a non-nil error response.
This change detects an empty-string Response.Error at the client, and
translates it into a nil value in Call.Error.
Tests updated to check error return in success cases.

crypto/rsa: handle the case of non-coprime blinds.
...
We are dealing with the multiplicative group ℤ/pqℤ. Multiples of
either p or q are not members of the group since they cannot have an
inverse. (Such numbers are 0 in the subgroup ℤ/pℤ.)
With p and q of typical size (> 512 bits), the probability of a random
blind [1..pq-1] being a multiple of p or q is negligible. However, in
the unit tests, much smaller sizes are used and the event could occur.
This change checks the result of the ext GCD and deals with this case.
It also increases the size of p and q in the unit test as a large
number of the keys selected were p, q = 227,169.
