bbf5eb5ba2 exp/template: delete upward evaluation.
It was an ill-advised carryover from the previous template package.
Also clean up function evaluation.
Also add a Name method to Template.

3236097ab0 cgi: don't depend on CGI.pm for tests

d1d466f620 crypto/x509: prevent chain cycles in Verify
It's possible to include a self-signed root certificate as an
intermediate and push Verify into a loop.

I already had a test for this so I thought that it was ok, but it
turns out that the test was void because the Verisign root certificate
doesn't contain the "IsCA" flag and so it wasn't an acceptable
intermediate certificate for that reason.

dd2074c82a sync: improve Mutex to allow successive acquisitions
This implementation allows a goroutine to do successive acquisitions
of a mutex even if there are blocked goroutines.
Moreover, it allows a newcomer goroutine to acquire a mutex ahead of
blocked goroutines (that is, it does not enforce FIFO).
On implementation level it's achieved by separating waiter count and
locked flag.

8ffbc4016a goinstall: Add support for generic hosts using special import form
This change extends goinstall to support "magic" package names of the
form:
        <host>/<repo>.<vcs>/<path>

Where <host> is the hostname, <repo> the path to the repository, <vcs>
the type of vcs (git, hg, bzr or svn), and <path> is the path inside the
repository that contains the source code for the package.

For example: "example.com/pub/foo.hg/src" means download the Mercurial
repository at either pub/foo.hg or pub/foo from example.com and then
build and install the source files from src inside the repository
checkout.

Repositories on the built-in hostings sites (github, bitbucket,
launchpad and googlecode) must still use the old form (i.e.
github.com/xxx/yyy.git/src will be rejected).

25733a94fd reflect: support for struct tag use by multiple packages
Each package using struct field tags assumes that
it is the only package storing data in the tag.
This CL adds support in package reflect for sharing
tags between multiple packages.  In this scheme, the
tags must be of the form

        key:"value" key2:"value2"

(raw strings help when writing that tag in Go source).

reflect.StructField's Tag field now has type StructTag
(a string type), which has method Get(key string) string
that returns the associated value.

Clients of json and xml will need to be updated.
Code that says

        type T struct {
                X int "name"
        }

should become

        type T struct {
                X int `json:"name"`  // or `xml:"name"`
        }

Use govet to identify struct tags that need to be changed
to use the new syntax.

cf143e9dbf ld: fix ELF strip by removing overlap of sections
The gosymtab and gopclntab sections were pointing to the proper
data, but that data was already owned by the rodata section.
Some ELF references explicitly prohibit multiple sections from
owning the same data, and strip behaves accordingly.

The data for these sections was moved to after rodata, and the
gosymtab and gopclntab sections now own their respective ranges.

This change makes strip happy both with and without -s being
provided at link time.  Note that it won't remove these sections
because they are still allocated, and that's by design since
they are necessary at runtime for generating proper backtraces
and similar introspection operations.

Unlike the previous behavior, -s will now maintain zero-sized
gosymtab and gopclntab sections.  This makes the implementation
slightly cleaner.

Fixes #1242.

NOTE: Tested on Linux amd64/386/arm only.

997c00f991 runtime: replace Semacquire/Semrelease implementation
1. The implementation uses distributed hash table of waitlists instead of a centralized one.
  It significantly improves scalability for uncontended semaphores.
2. The implementation provides wait-free fast-path for signalers.
3. The implementation uses less locks (1 lock/unlock instead of 5 for Semacquire).
4. runtime·ready() call is moved out of critical section.
5. Semacquire() does not call semwake().

combined, these can be used to check the
runtime.stdcall functions in the windows port
or in any other port that needs a vararg list of
uintptrs even on a 64-bit platform (where it is
very easy to pass a less-than-uintptr in the ...).

demo:

typedef unsigned int uintptr;

#pragma varargck countpos f 1
#pragma varargck type f uintptr
#pragma varargck type f void*

int f(int count, ...);

void *v;
char *p;

void
main(void)
{
        f(1, v);  // ok
        f(1, main);  // ok
        f(1, p);  // ok
        f(2, v, v);  // ok

        f(2, v);  // found 1 argument after count 2
        f(1, 'a');  // invalid type INT in call to f
        f(1, 0);  // invalid type INT in call to f
}
